Does the addition of perineal block enhance pain control after a haemorrhoidectomy? A prospective randomized, double-blind placebo-controlled study.

Haemorrhoidectomy is associated with severe postoperative pain, a long rehabilitation, and QoL worsening for months. Most patients experience mild-to-moderate postoperative pain. We aimed to evaluate the intraoperative perineal block role for patients undergoing haemorrhoidectomy. In this prospective randomized, double-blind, placebo-controlled study, eligible patients with III-IV stage haemorrhoids were randomized to the experimental group (EG) with intraoperative perineal block and spinal anaesthesia and the control one (CG) only with spinal anaesthesia. During the postoperative period, the opioid consumption rate was evaluated as a primary endpoint, and the postoperative pain level according to VAS, systemic analgesics consumption, readmission, and complication rate, the timing of returning to work, patients' QoL, and overall satisfaction according to SF-36 were evaluated as secondary endpoints. One hundred patients completed the study (48 in EG and 52 in CG). Patients of the EG had less postoperative pain intensity (P < 0.0001), required less opioid analgesia (P = 0.03), and had longer pain-free postoperative periods (P = 0.0002). 90% of patients in the CG required additional NSAID injections for adequate analgesia compared with only 58% in the EG. The average hospital stays, complication rate, and average operation duration didn't reach clinical significance. General health evaluation according to the SF-36 score and the median satisfaction rate was better in the EG (P < 0.001 and P = 0.012, respectively). The administration of the perianal block is safe and effective and should be administered to appropriate patients undergoing anorectal surgery.

Comparative Analysis of Efficacy of Endoscopic versus Open Carpal Tunnel Release

Objectives: To compare the efficacy between endoscopic and open carpal tunnel release procedures for carpal tunnel syndrome patients. Design and setting: Randomised control study in a single neurosurgery department Participants: 30 patients aged 35-69 years with clinically diagnosed carpal tunnel syndrome Main outcome measures: Primarily - operative duration, bleeding, pain score on day one, requirement of non-steroidal anti-inflammatory drugs (NSAIDs), time spent in hospital and days taken to return to work. Other outcomes include infection, wound status/cosmesis, injury to median nerve, chronic regional pain syndrome and patient satisfaction. Results: 15 patients were allocated to open surgery, and the other 15 for endoscopic. The average operative duration for open surgery was 9.9 minutes compared to 52 minutes spent for the endoscopic procedure. Cauterization had to be performed 4:1 times in endoscopic compared to open. Pain scores rated 3x higher after open surgery and resulted in increased NSAIDs use. Time spent in hospital after open surgery was 0.7 hours compared to 2.2 in endoscopic, however patients were able to return to work an average of 10.6 days earlier after endoscopic surgery. Conclusions: In carpal tunnel syndrome, endoscopic surgery allowed patients to experience less post-operative pain and return to work several days sooner than in open surgery.

Comparison of intraoperative hemodynamics in classical and single-port adrenalectomy

BACKGROUND: Pheochromocytoma (PCC) is a tumor from the chromaffin tissue of the adrenal medulla, capable of hyperproduction of catecholamines. An important feature of pheochromocytoma, due to its hormonal activity, is the threat of sudden changes in hemodynamic parameters during surgical treatment. Retroperitoneoscopic access is currently becoming increasingly popular in the surgical treatment of chromaffin tumors of the adrenal glands. In clinical practice, two variants of the mentioned access are used: classic (three-port) and single-port. In this study, the influence of these options of retroperitoneoscopic access on intraoperative hemodynamic control was evaluated.AIM: Comparison of treatment results and intraoperative hemodynamic parameters of patients with adrenal pheochromocytomas operated with single-port and three-port retroperitonescopic access options.MATERIALS AND METHODS: A retrospective single-center cohort study was conducted on a sample of patients initially operated for pheochromocytoma at the Pirogov St. Petersburg State University High Medical Technology Clinic from October 2015 to February 2020 with intraoperative invasive hemodynamic control using PiCCO+ systems.RESULTS: 47 patients were examined, 24 of whom underwent single–port adrenalectomy (included in the first group), 23 — three-port (second group). The average tumor size in the second group was larger (40.12±9.3 and 56.7±21.5, p&lt;0.05), presumably, in this regard, the average duration of surgery was statistically significantly higher (73±21.5 and 111.7±36.1, p&lt;0.05). The body mass index (BMI) of patients in the two groups did not differ statistically significantly. Intraoperatively measured values of maximum and minimum mean systolic and diastolic blood pressure, the number of episodes of increased diastolic blood pressure above 120 mmHg and their duration did not differ statistically in both groups (p&gt;0.05). Episodes of increased systolic blood pressure above 180 mm Hg were more frequent in the second group (p=0.03), but their total duration in the two groups was without significant differences (p&gt;0.05). Intraoperative consumption of antihypertensive drugs during the release of the adrenal gland and vasopressor drugs after compression of the central vein of the adrenal gland were similar. Blood pressure after compression of the central vein in the first and second groups did not differ significantly (p&gt;0.05). No deaths and postoperative complications were registered in both groups.CONCLUSION: Single-port modification of retroperitoneoscopic access with sufficient experience of the anesthesiological team and the operating surgeon does not lead to deterioration of hemodynamic control and operation results, being safe and effective in the surgical treatment of pheochromocytoma.

Endoscopic Membranectomy's Role in the Treatment of Nonhomogeneous Chronic Subdural Hematoma (EMiT-CSDH): Prospective Single-arm Interventional Pilot Study

Chronic subdural hematoma (CSDH) is a prevalent neurosurgical condition characterized by blood accumulation within the border cell layer. Despite various treatment options-medical, endovascular, and surgical-recurrence rates remain high. Our pilot study investigates the safety and efficacy of endoscopic membranectomy (EM) in reducing recurrence in nonhomogenous CSDH. This was a prospective single-arm interventional pilot study from March to June 2023. It included patients of all ages who presented with symptomatic nonhomogenous CSDH requiring surgical intervention. A total of 19 patients were enrolled in this study. The average age was 60.4 ± 10.4 years. The male:female ratio was 5.3:1. In this group, 73.7% (n= 14) of patients had a history of trauma. All patients presented with a history of altered sensorium and contralateral limb weakness. The most common type of CSDH was trabecular (42.1%), followed by gradient (21%), separated (15.8%), and laminar (15.8%). The average duration of surgery was 43.42 ± 10 minutes. CSDH may be thin or thick based on its tractability and has significance in EM technique. All patients started recovering within 24 hours. All patients were asymptomatic, without any neurologic deficit, at 2 weeks, and remained so at the 6-month review. In 17 patients, the 6-month follow-up computed tomography did not show any bleeding/recurrence. There were no postoperative seizures, wound-healing issues, or infections. There are multiple treatment options for CSDH at present. EM is a potentially safe and effective treatment for CSDH, with lower recurrence and faster recovery. Large-scale controlled studies on EM are required.

The value of computer reconstruction in the treatment of intra-articular fractures of the distal part of the humerus

The aim of the work was to study the role of computer reconstruction and additive technologies in the planning of surgical treatment of intra-articular fractures of the distal part of the humerus in the early post-traumatic period. Materials and methods: the results of treatment of 44 patients with fractures of the distal part of the humerus aged from 22 to 65 years were studied. All patients underwent MSCT in the preoperative period. In 45.5 % (20) cases, in order to increase the effectiveness of preoperative planning, simulation osteosynthesis was performed on an individual printed model of the damaged bone. After completion of preoperative planning, all patients underwent osseous metallo-osteosynthesis in the first week after receiving the injury. In order to assess the effectiveness of the application of visualization techniques, a survey of the operating team was carried out regarding the informativeness of the conducted instrumental studies. Results. The average duration of surgical intervention among patients in the clinical group with standard preoperative planning was 105.9 ± 9.15 minutes. The average results of the survey of the surgical team after the surgical interventions in the specified clinical group were 21.2 ± 2.8 points. The average duration of surgery among patients of the second clinical group, whose preoperative planning included not only the assessment of MSCT results of the damaged segment, but also simulated osteosynthesis with the selection and application of optimal metal fixators, was 54.6 ± 7.14 minutes. The average results of the survey of the surgical team were 31.2 ± 1.7 points. Conclusions. The use of a combination of visualization technologies and 3D printing allows to reduce the time the patient spends in the operating room and increase the effectiveness of preoperative planning. Performing simulated osteosynthesis in the preoperative period allows you to develop an individual technique of repositioning bone fragments and use the optimal standard size of the cortical metal fixator with the distribution of the most favourable compression points of bone fragments

LIMBERG FLAP VERSUS BASCOM CLEFT LIFT TECHNIQUES FOR SACROCOCCYGEAL PILONIDAL SINUS

Objective: The study aims to evaluate and compare the outcomes of two surgical techniques, the limberg flap and Bascom cleft lift, used in the treatment of sacrococcygeal pilonidal sinus. Key metrics for comparison include postoperative complications, hospital stay duration, and surgery duration. Methods: This was a prospective study conducted at ESIC Hospital, Jaipur, involving 100 patients diagnosed with sacrococcygeal pilonidal sinus requiring surgical intervention. Patients were divided into two groups: Group I underwent the Bascom cleft lift procedure (n=40), and Group II underwent the limberg flap technique (n=60). Both groups were evaluated over a period of one and a half years with preoperative assessments and postoperative follow-ups for complications, duration of surgery, and length of hospital stay. Results: The study included 40 patients in the Bascom group (42.5% male, 57.5% female) and 60 in the limberg group (55% male, 45% female). The average surgery duration was significantly shorter for the Bascom procedure (36.73±6.52 min) compared to the limberg flap (74.58±10.10 min). Postoperative complications were higher in the limberg flap group. The Bascom cleft lift patients experienced shorter hospital stays and fewer postoperative issues, including lower rates of discharge and infection. Conclusion: The Bascom cleft lift procedure appears to be superior to the limberg flap in terms of shorter operative time, fewer complications, and quicker recovery. These findings suggest that the Bascom cleft lift could be a more efficient and safer option for the surgical treatment of pilonidal sinus, promoting faster patient recovery with fewer postoperative complications.

OVERVIEW OF ANEMIA AFTER SCOLIOSIS SURGERY IN THE INTENSIVE CARE UNIT (ICU) SOEHARSO ORTHOPEDIC HOSPITALINDONESIA

Anemia is a condition where the hemoglobin concentration is lower than normal. This condition reflects the lack of the normal number of erythrocytes in the body's circulation and consequently the amount of oxygen delivered to the body's tissues is also reduced. Miller &amp; Thompson (2019) scoliosis comes from the Greek word "scoliosis" which means crooked. Scoliosis is a complex three-dimensional deformity of the spine characterized by a lateral deviation of at least 10 degrees with spinal rotation and is usually associated with a reduction in the normal kyphotic curvature of the spine / hypokyphosis. The cause of bleeding in spinal surgery usually occurs more in cases of rigid scoliosis, pedicle subtraction osteotomy and vertebral column resection often referred to as triple column osteotomy and is considered a procedure with a high risk of complications with massive blood loss, reaching more than 10 liters (Jun. 2019). Based on its classification, this type of research is retrospective descriptive research. studies that discuss one or more variables separately, one-by-one, but do not examine the relationship between these variables, using the observation method with the subject being observed by looking at past conditions (Harlan &amp;Sutjiati, 2022). Using total sampling technique in sampling, the population is the medical records of patients admitted to the ICU, postoperative diagnosis of scoliosis with anemia, the sample size is 58 patient medical records. The variables observed were: indications for ICU admission and postoperative scoliosis, the inclusion criteria were medical record data for postoperative scoliosis patients with anemia admitted to the ICU for the period January 1 - December 31, 2022 and patients with the first scoliosis surgery. Based on this study, the following results were obtained: Most respondents were female (81%), the average age of respondents was 17 years. The most common type of scoliosis is adolescence idiopathic scoliosis (89.7%). The most Lenke classification is Lenke 3 (44.8%), the most types of surgery are stabilization, fusion, discectomy, laminectomy and osteotomy (56.9%). The duration of surgery was mostly 180-240 minutes (46.6%) with an average duration of surgery of 257 minutes, the average amount of bleeding was 884.5 ml, the average preoperative Hb was 13.3g/dL, the average postoperative Hb was 8.8 g/dL. The average postoperative Hemoglobin decrease was 5.3 g/dL, patients who were given blood transfusions (87.9%) with an average of 2.9 bags per patient, the most common type of transfused blood was PRC (90.2%).

Frequency of Early Complications of Laparoscopic Sleeve Gastrectomy Using Four Ports.

Background Laparoscopic sleeve gastrectomy (LSG) has become a widely accepted bariatric procedure for treating morbid obesity and associated comorbidities due to its relatively straightforward technique and positive outcomes in terms of weight loss and metabolic improvement. Objective To investigate the frequency and types of early complications followingLSGusing four ports. Methods This prospective observational study was conducted at Al Hadi International Hospital, Swabi, Pakistan, from January 2022 to December 2022. A total of 369 patients aged 25-65 years with a BMI of 35-55 kg/m2 were included. Data on demographic characteristics, surgery duration, intraoperative blood loss, and hospital stay were collected. Early complications within 30 days post-surgery, including bleeding, infection, and leakage, were documented. Statistical analyses were performed using IBM SPSS Statistics for Windows, Version 26 (Released 2019; IBM Corp., Armonk, New York, United States). Results The mean age of patients was 43.6 years (SD = 11.8) and the mean BMI was 42.3 kg/m2 (SD = 6.5). The average surgery duration was 92 minutes (SD = 22) and the mean intraoperative blood loss was 100 mL (SD = 50). Early complications occurred in 18% of patients with bleeding, infection, and leakage each accounting for 5%, 4%, and 3%, respectively. Reoperation was required in 5% of patients due to these complications. Higher BMI (45.2 vs. 41.8 kg/m2, p = 0.04) and longer surgery duration (105 vs. 88 minutes, p = 0.03) were significantly associated with increased complication rates. Comorbidities were present in 60% of patients with complications compared to 34% without complications (p = 0.03). Conclusion The four-port technique in LSG is associated with an 18% early complication rate with significant risk factors being higher BMI and longer surgery duration. Careful patient selection, standardized surgical techniques, and robust postoperative care are essential to minimize complications and improve outcomes in LSG.

Arthroscopic Bankart Repair Using 1 Anterior Portal Has a Shorter Surgical Time and Comparable Clinical Results With the Standard 2-Portal Technique

PurposeTo assess the modified one anteriorportal Bankart repair and compare it to the two-portal Bankart repair in terms of surgical time, functional scores, and recurrent dislocation. Material and MethodsPatients who underwent Bankart repair from 2014 to 2021 were identified and separated into two groups: a modified one anterior portal group and a two anterior portal group. The inclusion criteria were being >18 years old, having a recurrent anterior shoulder dislocation with a Bankart lesion, and having a minimum of 2 years of follow-up. Patients were evaluated for their clinical results using the American Shoulder and Elbow Surgeons (ASES) score, the Western Ontario Shoulder Instability (WOSI) Index, and the Oxford Shoulder Instability Score (OSIS) pre- and post-operatively. The duration of surgery and recurrent instability were recorded. To prevent suture tangling in the modified one-portal group, two techniques were performed: "cannula in canulla” and "cannula in and out." ResultsA total of 42 subjects were included in this study, with 20 in the modified one portal group and 22 in the two-portal group. There were no statistically significant differences between the two groups in clinical scores obtained after two years of surgery (ASES score p =0.5, WOSI index p =0.22, and OSIS score p =0.32). The average surgical duration in the modified one-portal group (65.7±15.8) was significantly shorter than the average surgery duration in the two-portal group (81.1±27.2). (p=0.03). There was no statistically significant difference between the two groups for recurrent instability. (p=1.0) ConclusionBankart repair performed through a modified one anterior portal technique has a shorter surgical time and similar clinical outcomes as the two-portal technique.

Understanding Techniques, Risks, and Recovery for Enhanced Patient Care of Laparoscopic Appendectomy

Introduction: Because laparoscopic appendectomy is a less intrusive procedure with good results, it has become the accepted surgical treatment for acute appendicitis. In order to improve patient care, this study sought to thoroughly examine the methods, related hazards, and recuperation times of laparoscopic appendectomy. Methodology: A retrospective cohort study comprising 87 patients who had laparoscopic appendectomy between June 2023 and May 2024 was carried out at District Headquarters (DHQ) Hospital Kohat. Patient demographics, surgery specifics, problems, and recovery results were all recorded. To assess the data, statistical analysis such as t-tests and chi-square tests were carried out. Results: The study population's mean age was 34.5 years, and its male to female ratio was slightly greater (57.5%). The average operating duration was 65.2 minutes, and in 13.8% and 39.1% of cases, respectively, differences in surgical technique—such as the use of SILS and advanced energy devices—were noted. The incidence of complications was minimal, with 2.3% of patients experiencing intraoperative injuries, 8.0% experiencing postoperative infections, and 4.6% developing abscesses. There were no discernible variations between male and female patients' recovery results or complication rates. Conclusion: This study demonstrates that laparoscopic appendectomy is safe, effective, and has a low risk of complications and good recovery results when treating acute appendicitis. The results validate laparoscopic procedures as the gold standard surgical method. To improve surgical methods and postoperative care guidelines and eventually improve patient outcomes, further research is necessary.

Therapeutic Options in Hydatid Hepatic Cyst Surgery: A Retrospective Analysis of Three Surgical Approaches.

Hydatid disease is endemic in certain geographical areas where animal breeding is common, frequently challenging the medical services in these regions. Hydatid cysts most often affect the liver, with damage to other organs accounting for around one-third of the total cases. The alternative to interventional or pharmacological approaches is surgical treatment, available in variants such as laparoscopy, laparoscopy with special instruments for hydatid disease, or open surgery. This article aims to analyze the outcomes of these three types of surgical approaches, considering preoperative indications, operative techniques and efficiency, and immediate and long-term postoperative results. A total of 149 patients from two different surgical units were analyzed over a period of seven years. It was observed that males were more affected by this pathology (53.02%), with the majority of patients coming from rural areas (62.42%). The distribution by surgical procedure type showed that 50.34% were operated on using open surgery, 33.56% by means of a laparoscopic approach with the usual instruments, and 16.11% by means of a laparoscopic approach with special instruments. The laparoscopic procedure with special instruments presented a lower rate of conversion to open surgery compared to the usual laparoscopic approach (p = 0.014). The analysis of the average operative duration revealed statistically significant differences between the three types of surgical techniques (p < 0.05), noting that interventions with specialized instruments had the shortest duration, while open surgery had the longest operative time (72.5 ± 27.23 min vs. 154 ± 52.04 min). In terms of intraoperative complications, they were documented in 8.34% of cases for the group operated on with special instruments, in 12.24% of cases for the standard laparoscopy group, and in 16% of cases for the open surgery group. Maximal cystectomy was the preferred method for resolving these cysts using minimally invasive surgery (p < 0.001), while Lagrot pericystectomy was preferred in the open approach (p < 0.001). The most frequent postoperative complication was biliary fistula (24.16%), encountered in varying percentages across each technique but without significant statistical difference (p > 0.05). Open surgery was associated with a longer length of hospitalization compared to minimally invasive procedures (p < 0.05), a higher number of late postoperative complications (p = 0.002), and a significantly higher number of recurrences (p < 0.001) compared to the other two techniques. The present study highlights the effectiveness of minimally invasive surgery for hydatid cysts as a safe alternative with fewer complications and superior results compared to open surgery. Additionally, it provides a comparative analysis of these surgical approaches (special instruments, standard laparoscopy, and open surgery) to hydatid disease for the first time. Under the circumstances where pharmacological treatment is recommended as a supportive measure before and after procedures, and using medication alone as the primary treatment option shows only modest efficacy, there is a necessity to consider invasive treatment methods. Percutaneous procedures represent the least invasive form of treatment, yielding results comparable to surgery in terms of efficacy. However, their effectiveness is influenced by factors such as the cyst's stage of development, its location, and the challenges in achieving complete intra-procedural isolation. Laparoscopy, particularly when using specialized instruments tailored to the tactical and technical demands of managing hydatid disease, serves to address the limitations of percutaneous methods. Open surgery's role is increasingly restricted, primarily serving as a fallback option in laparoscopic procedures or in cases complicated by hydatid disease. In conclusion, despite the rising popularity of percutaneous methods, surgery remains a viable therapeutic option for treating hydatid disease. Minimally invasive surgical interventions are increasingly versatile and yield comparable outcomes, further solidifying the role of surgery in its management.

Срединная кольпорафия как способ коррекции пролапса гениталий у пациенток пожилого и старческого возраста.

Introduction. The problem of genital prolapse (PG) remains relevant due to its high prevalence, reaching its maximum frequency in elderly women. When choosing surgical treatment of PG in the elderly and senile, it is necessary to take into account the presence of extragenital pathology and the somatic status of the patient. One of the methods of PG correction is median colporaphy, which has a high safety profile and a low recurrence rate. The aim of the study was to evaluate the results of median colporaphy in elderly and senile patients with genital prolapse. Materials and methods. The study included 40 women aged 65 years and older with symptomatic PG III-IV degree (POP-Q), who did not have sexual intercourse and did not seek it in the future, who underwent median colporaphy using the Lefor-Neugebauer technique in combination with colpoperineolevatoroplasty. The results of surgical treatment were evaluated according to the following criteria: duration of surgery, intra- and post- operative complications, assessment of the degree of PG before and after surgery, functional and anatomical results of surgery, duration of hospital stay, assessment of symptoms of PG before and after treatment. The follow-up period for patients is from 1 to 5 years after surgery. Results. The average duration of surgery is 41.5±9.6 minutes. The average volume of intraoperative blood loss was 55.5±20.1 ml. One intraoperative complication was registered – damage to the bladder wall. The average length of hospital stay is 5.6±1.0 days. No recurrence of PG was noted. Ac- cording to The Overactive Blade Questionnaire (OAB-q), there was an improvement in the average score from 9.9+6.0 to 7.3+2.7, which indicated a decrease in the severity of PG symptoms. The frequency of dysuric phenomena after surgery decreased by 2.2 times. Urinary disorders after surgery were detected in 15 (37.5%) patients; stress urinary incontinence – in 9 (22.5%) patients, in 6 (15.0%) – de novo, imperative urinary incontinence de novo – in 1 (2.5%) case. According to the Pelvic Floor Distress Inventory questionnaire (PFDI-20), there was a decrease in symptoms and func- tional disorders of the bladder and intestines in patients: a decrease in the number of points on the POPDI-6 scale from 62.1+18.9 to 1.4+3.7; CRAD-8 – from 18.0+14.8 points to 0.7+2.1; UDI-6 – from 29.9+23 to 7.1+10.2. According to an oral survey, all 40 (100%) patients would agree to undergo this operation again and not a single patient regretted the loss of sexual function. Conclusions. Median colporaphy is a safe and effective way to correct genital prolapse in elderly and senile women, including those with a burdened somatic status, who agree to give up vaginal intercourse. It is necessary to carefully inform patients about the irreversibility of vaginal obliteration and about the possible occurrence of dysuric phenomena after surgery.

The Lateral Para-Patellar Approach for Intramedullary Tibia Nailing in Distal Tibia Extra-articular Fractures: A Prospective Cohort Study.

The treatment of extra-articular distal tibiafractures is still a subject of debate and frequently necessitates surgical treatment, and intramedullary nailing (IMN) offers a minimally invasive approach with excellent results. Important factors in these procedures are positioning, operative duration, and radiation exposure. This study details the semi-extended lateral para-patellar approach for IMN of distal tibia extra-articular fractures and documents our findings regarding operative time, intra-operative radiation exposure, residual anterior knee pain, knee functional and radiological outcomes at six months follow-up. We reviewed the cases of 60 patients who underwent IMNfor distal tibia extra-articular fractures from May 2022 to March 2024, employing an extra-articular lateral para-patellar approach in the semi-extended position. Patients were evaluated clinically and radio-graphically for a minimum follow-up period of six months. Data collected included duration of surgery, intraoperative radiation exposure, and knee functional scorefor all patients. Assessment of fracture healing, residual deformities, residual anterior knee pain, and range of motion of the treated knee compared to the contralateral knee was done at a six-monthfollow-up. The average surgery duration was 54 ± 5 minutes, with intraoperative imaging averaging 48 exposures. The average time to union was 16 ± 3 weeks. Six months post-surgery, the mean Knee Society Score was 86.4 ± 3.5 (out of 100). At the six months follow-up, all patients exhibited clinical and radiographic healing, with only two cases showing mal-alignment (angular deformity <10 degrees).All patients regained a comparable range of motion in their knees. The semi-extended lateral para-patellar approachfor nailing of distal tibiaextra-articular fracturesenhances reduction, simplifies nail insertion,reduces both fluoroscopy and operative time, minimizes anterior knee pain and improves knee functional outcomes at six months follow-up.

Do All Postoperative Vancouver B2 Fractures Require Revision Arthroplasty With Cementless Stems?

BackgroundManagement of periprosthetic fractures has been guided by the Vancouver classification, which recommends revision for fractures around a loose femoral implant (B2). New studies have challenged this approach, demonstrating acceptable outcomes with internal fixation. This study evaluates our experience with Vancouver B2 fractures, comparing internal fixation to femoral revision. We hypothesized that in select cases with cementless stems, internal fixation would provide acceptable results with reduced morbidity. MethodsA retrospective review was performed of periprosthetic hip fractures treated at our institution between 1 January 2012 and 4 November 2022. We excluded patients who did not have prior radiographs and evidence of stem subsidence, suggestive of a Vancouver B2 fracture. Thirteen patients were included in the analysis. ResultsFour patients (31%) underwent revision of the femoral component, 4 patients (31%) underwent plating, and 5 patients (38%) underwent internal fixation with cerclage cabling. The average operative duration was 158 minutes, 203 minutes, and 62 minutes for the revision, plating, and cabling cohorts, respectively (P = .009). Blood loss was 463 cc, 510 cc, and 90 cc for the revision, plating, and cabling cohorts, respectively (P = .036). Three patients in both the revision and plating cohorts each received a transfusion (75%), whereas no patients in the cabling cohort required a transfusion (P = .033). All patients demonstrated fracture healing on the postoperative radiographs. No patients required additional surgery during the follow-up period. ConclusionsWe have demonstrated that Vancouver B2 periprosthetic fractures with intact lateral cortices may be treated with internal fixation with cerclage cabling with excellent results.

Anatomic and Surgical Aspects of Total Pancreatectomy in Swine

IntroductionThe swine is valuable model for preclinical research and surgical technique training. From the induction of Diabetes through total pancreatectomy, these animals can be used in many research studies, such as islet transplantation. In view of the lack of elucidation in literature, the purpose of this work is to describe anatomical aspects, surgical technique of total pancreatectomy, intra- and postoperative complications and autopsy results Material and MethodFive male pigs, hybrids (Large White/Landrace), 20-35 kg, submitted to total pancreatectomy with duodenum, bile duct and spleen preservation. Postoperatively, daily clinical assessment and capillary blood glucose collection were performed. At the end of the 30-day limit or in the occurrence of serious clinical complications, euthanasia and autopsy were performed ResultsThe average duration of surgery was 128 minutes, without intraoperative deaths or anesthesia induction failures. Median survival was 6.6 days. Postoperative complications were weight loss (3), emesis (2), constipation (2), abdominal distension (2), diarrhea (1) and loss of appetite (1). All animals were euthanized due to serious complications. Two animals presented surgical complications (duodenal necrosis with gastroparesis and internal hernia with intestinal necrosis). The other three animals presented serious clinical complications related to exocrine pancreatic insufficiency due to deficiency of pancreatic enzymes. Glycemic values above 200 mg/dL were found on the first postoperative day and above 300 mg/dL on the seventh day in all animals Discussion and ConclusionsIn this experiment, a model of total pancreatectomy with duodenum, spleen and bile duct preservation in pigs was established. All animals had diabetes, however animals without postoperative complications were euthanized due to serious complications related to pancreas exocrine insufficiency.

A Comparative Study of 2 Techniques to Avoid Bone Cement Loosening and Displacement After Percutaneous Vertebroplasty Treating Unstable Kummell Disease.

Percutaneous vertebroplasty (PVP) is currently the most common surgical procedure for unstable Kummell disease (KD), but cement loosening or displacement often occurs after PVP. We had been using percutaneous pediculoplasty (PPP) or a self-developed bone cement bridging screw system to avoid this severe complication. This study intends to compare these novel surgical procedures through a 2-year follow-up evaluation. From May 2017 to May 2021, 77 patients with single-level unstable KD were included in the PPP group, and 42 patients received the PVP-bone cement bridging screw system were included in the screw group. The changes in the vertebral body index (VBI), bisegmental Cobb angle, visual analogue scale (VAS) and Oswestry Disability Index (ODI) and the cement loosening rate and displacement rate at different follow-up time points were used to evaluate the clinical efficacy. There was no significant difference in VBI or bisegmental Cobb angle between the 2 groups (p > 0.05) before operation, immediately after operation and at 6-month followup, while at 1-year and 2-year postoperative evaluations, the screw group had higher VBI and bisegmental Cobb angle than the PPP group (p < 0.05). Before operation, immediately after operation, at 6-month and 1-year follow-up, there was no significant difference in VAS or ODI score between the 2 groups (p > 0.05), while at 2-year follow-up, the screw group still had higher VAS and ODI scores than the PPP group (p < 0.05). No bone cement displacement occurred in both groups, but the rate of bone cement loosening was 14.29% in group PPP, and 0 in screw group (p < 0.05). This 2-year follow-up study shows that the PVP-bone cement bridging screw system combined therapy had better midterm treatment efficacy than the PVP-PPP combined therapy in patients with unstable KD, and the bone cement bridging screw system is a preferred therapy with better anti cement loosening ability.

Comparative analysis of robot-assisted and laparoscopic operations in oncogynecology

Aim. To determine the advantages and disadvantages of laparoscopic (LS) and robot-assisted (RA) surgery in oncogynecological operations.Materials and methods. 282 clinical cases were retrospectively analyzed. The patients were treated in oncogynecological department No. 70 of the CS.P. Botkin City Clinical Hospital, Moscow Healthcare Department for endometrial cancer of stages IA–II, cervical cancer in situ and IA1 stages or atypical endometrial hyperplasia in the period from February 2020 to September 2022, among them 74 patients were operated with Da Vinci robotic units (models Si and Xi) and 208 using laparoscopy. The standard volumes of surgical treatment, depending on the clinical diagnosis, were: hysterectomy, hysterectomy with pelvic lymphadenectomy, hysterectomy with pelvic and retroperitoneal lumbar lymphadenectomy. To compare the technical characteristics of minimally invasive operations and the condition of patients in the intra- and postoperative periods in each group, data on the duration of operations, body mass index, age, intra- and postoperative complications, as well as the number of postoperative hospital bed-days were analyzed.Results. When comparing the average duration of operations by time, a statistically significant difference was obtained. Thus, LS hysterectomy was performed 43 minutes faster on average than RA (74.2 minutes versus 117 minutes) (p &lt;0.001). When performing pelvic lymphadenectomy, the average duration of RA operations was 28 minutes longer than LS operations (142 minutes versus 170 minutes), and when adding the retroperitoneal lymphadenectomy stage, the average duration of RA operations was 128 minutes longer than LS operations.Conclusion. At this stage of technology development in surgery, LS operations have a number of advantages over RA ones in numerous ways. LS operations demonstrate statistically significantly shorter execution time, fewer perioperative complications, as well as a more controlled environment in the operating field. In the long term, RA surgery has serious potential and is currently at an early stage of its development. A real and sober assessment of its characteristics will determine the right direction for the development of this technology in the future.

The management of goal-directed fluid therapy during cytoreductive surgery and hyperthermic intraperitoneal chemotherapy.

Cytoreductive surgery is a surgical treatment approach that has been applied over the last 3 decades in patients with peritoneal metastases originating from intraabdominal organs. Goal-directed fluid therapy (GDFT) is an approach in which a patient fluid therapy during a medical procedure or surgery is carefully managed based on a specific goal. In this study, we aimed to present the results of GDFT in patients who underwent cytoreductive surgery for peritoneal carcinomatosis (PC) during the perioperative period. This retrospective study included 398 patients patient who underwent cytoreductive surgery + hyperthermic intraperitoneal chemotherapy (CRS + HIPEC) due to PC originating from intraabdominal malignancies. Of the cases, 233 (58.6%) were female, and 165 (41.4%) were male patients. The mean age was 58.9. Perioperative findings revealed an average PC score of 12 (3-24), average lactate levels of 3 (2-7) mmol/L, Pao2/fio2 of 3.3 (2.4-4.1) mm Hg, mean arterial pressure (MAP) of 60 (55-70), average surgery duration of 6.5 hours (3-14), and average blood loss of 400 (200-4000) cc. The mean intraoperative fluid rate was 6.4 mL/kg/h (IQR 5.8-7.1). Sixteen (16.3%) patients experienced Clavien-Dindo Grade 3-4 adverse events. Within 30 days, 25 patients (6.3%) died. CRS + HIPEC procedures utilizing perioperative GDFT along with advanced anesthesia monitoring devices have shown successful application, offering an alternative to traditional and restrictive fluid management approaches.

Retrospective evaluation of radiological and clinical outcomes after surgical treatment of proximal femoral fractures utilizing PFNA and PFNA augmented

IntroductionThe primary aim of this study was to evaluate the clinical and radiological outcomes after surgical treatment of proximal femoral fractures utilizing the Proximal Femoral Nail Antirotation (PFNA), with the main focus on complications and reoperations. The secondary aim was to compare the outcomes of patients with and without cement augmentation of the cephalomedullary nails.Materials and methodsAll patients with an acute proximal femoral fracture consequently treated with a PFNA between January 2011 and Dezember 2018 were evaluated. Clinical and radiological data were assessed for intra- and postoperative complications, including treatment failure. In addition, intra- and postoperative radiographs were used to determine the position of the implant, and any migration, via Tip-Apex-Distance (TAD) and the caput-collum-diaphyseal angle (CCD). The accuracy of the fracture reduction was rated according to Baumgaertners criteria.ResultsTwo hundred sixty-four consecutive patients (mean age 78.8 ± 12.0; 73.1% female) were included. The predominant OTA/AO fracture classification was 31A1 (153 cases, 58.0%). The average duration of surgery was 63.1 ± 28.0 min and showed no significant differences between PFNA and PFNA with augmentation. The implant positioning was rated as good in 222 cases (84.1%). Two hundred sixty-three patients (99.6%) showed evidence of healing within the time frame of three months postoperatively, one case of delayed union healed after secondary dynamization. During the observational period, 18 patients (6.8%) required a total of 23 additional surgeries. Overall, a lower reoperation rate was observed following the use of the augmentation option (2/86 patients (2.3%) vs. 16/178 patients (9.0%), p = 0.04). In particular, there were no cases of cut-out or cut-through among patients who underwent augmentation as part of osteosynthesis.ConclusionsOverall reoperation rate after surgical treatment of proximal femoral fractures utilizing the Proximal Femoral Nail Antirotation (PFNA) was 6.8%, with 23 additional surgeries performed in 18 patients. The usage of the PFNA with augmentation showed equally good implant positioning, excellent healing rates and fewer postoperative complications compared to the PFNA implant alone with a similar overall duration of surgery.

The learning curve of a novel seven-axis robot-assisted total hip arthroplasty system: a randomized controlled trial

BacgroundThe aim of this study was to assess the learning curve of a novel seven-axis robot-assisted total hip arthroplasty (RaTHA) system.MethodsA total of 59 patients who underwent unilateral total hip arthroplasty at our institution from June 2022 to September 2022 were prospectively included in the study. In this randomized controlled clinical trial, robot-assisted THA (RaTHA) and Conventional THA (CoTHA) were performed using cumulative sum (CUSUM) analysis to evaluate the learning curve of the RaTHA system. The demographic data, preopera1tive clinical data, duration of operation, postoperative Harris Hip Score (HHS), postoperative Western Ontario and McMaster Universities Arthritis Index (WOMAC) score, and duration of operation between the learning stage and the proficiency stage of the RaTHA group were compared between the two groups.ResultsThe average duration of operation of the RaTHA group was increased by 34.73 min compared with the CoTHA group (104.26 ± 19.33 vs. 69.53 ± 18.38 min, p < 0.01). The learning curve of the RaTHA system can be divided into learning stage and proficiency stage, and the former consists of the first 13 cases by CUSUM analysis. In the RaTHA group, the duration of operation decreased by 29.75 min in the proficiency stage compared to the learning stage (121.12 ± 12.84 vs.91.37 ± 12.92, p < 0.01).ConclusionsThis study demonstrated that the surgical team required a learning curve of 13 cases to become proficient using the RaTHA system. The duration of operation, total blood loss, and drainage gradually shortened (decreased) with the learning curve stage, and the differences were statistically significant.Trial registrationNumber: ChiCTR2200061630, Date: 29/06/2022.
