Effect of Anesthesia Type on Pain and Hemodynamic Parameters in Cesarean Section Surgery: Randomized Controlled Trial

Background: General and spinal anesthesia are commonly used for cesarean sections, each with implications for both the mother and the fetus. The choice of anesthesia technique depends on various factors. While spinal anesthesia is often preferred for cesarean surgeries due to its well-known benefits, general anesthesia may be chosen in emergency situations. The decision is ultimately based on the safety profile and benefits for both the mother and the fetus. Methods: This clinical trial was conducted at Fatemieh Hospital in Hamadan and involved 60 patients undergoing elective cesarean section. The patients were randomly divided into two groups of 30: One group received spinal anesthesia, and the other group received general anesthesia. Variables such as intraoperative bleeding, the Apgar score of the newborn, postoperative pain, and postoperative systolic and diastolic blood pressure were analyzed and compared between the two groups using SPSS software version 16. Results: The mean age of participants in the spinal and general anesthesia groups was 32 ± 3.5 years and 34 ± 3.4 years, respectively. The results showed that the amount of intraoperative bleeding in the general anesthesia group was higher than in the spinal anesthesia group, but this difference was not statistically significant (P = 0.85, P < 0.05). The Apgar scores at the first and fifth minutes in the spinal anesthesia group were higher than those in the general anesthesia group, but this difference was also not statistically significant (P = 0.32, P < 0.05). Postoperative pain in the spinal anesthesia group was significantly lower than in the general anesthesia group (P = 0.001, P < 0.05). Regarding hemodynamic parameters, systolic blood pressure after the operation was higher in the spinal anesthesia group compared to the general anesthesia group (P < 0.05). Conversely, diastolic blood pressure in the general anesthesia group was higher than in the spinal anesthesia group at all measurement stages, though not statistically significant in some measurements (P > 0.05). Conclusions: The results of our study indicate that spinal anesthesia is a preferable and safer method compared to general anesthesia, based on the parameters examined, particularly in emergency cesarean sections.

Analysis of risk factors for intraoperative bleeding in patients with Siewert type II esophagogastric junction adenocarcinoma treated by two minimally invasive surgeries and its influence on prognosis: a retrospective study.

The present study aimed to analyze the independent risk factors for intraoperative bleeding in Siewert II adenocarcinoma of the esophagogastric junction (AEG) using two minimally invasive surgical approaches, namely, the laparoscopy-assisted abdominal trans-hiatal (LTH) method and transthoracic-laparoscopic esophagectomy (TLE). The clinical data of 100 patients with SiewertII AEG admitted to our hospital from October 2017 to October 2020 were retrospectively analyzed. According to the type of surgery, the patients were divided into LTH approach group and TLE approach group. The differences between the clinical characteristics of the patients in different groups and the differences in the intraoperative bleeding and prognosis between different surgical procedures were analyzed and compared using the t-test and chi-squared test. Multiple linear regression was used to identify the independent risk factors affecting the amount of intraoperative bleeding in patients. The results of this study showed that patients in the LTH group had significantly less intraoperative bleeding and operative time and significantly better postoperative recovery than the TLE group. The results of multivariate linear regression showed that the combined trans-thoracic-abdominal approach (P=0.000), advanced age (P=0.014), larger BMI (P=0.000), and larger tumor diameter (P=0.001) were the independent risk factors influencing the increase in intraoperative bleeding. In addition to the conventional factors that affect intraoperative bleeding, such as the patient's general condition, operation time, and tumor size, LTH surgery is another way to avoid intraoperative bleeding for Siewert type II AEG patients and can significantly improve postoperative recovery.

The effects of prophylactic administration of tranexamic acid on the operative time and the amount of blood transfused during open fixation of pelvis and acetabulum fractures

BackgroundOrthopedic surgeons face challenges regarding perioperative bleeding during the operations of pelvic and acetabular fracture cases. Although the recently popular tranexamic acid (TXA) has proven to be a useful tool, this study primarily aimed to conduct a retrospective comparative analysis of the results of the prophylactic administration of tranexamic acid during open fixation of pelvis and acetabulum fractures, especially regarding operative time and the amount of blood transfused; and in addition, share the results related to other findings including the management of the erythrocyte suspension use and overall cost as secondary aims and thus providing a comprehensive point of view.MethodsThe files of patients with pelvis or acetabulum fractures admitted to the Emergency Clinic of the Adana City Training and Research Hospital between January 1, 2020, and December 31, 2023, were analyzed retrospectively. The inclusion criteria were as follows: patients aged 18 years or older who had undergone open reduction for pelvis or acetabulum fractures.ResultsThere were 78 files identified for analysis. Among the fractures, 27 were located at the pelvis (34.61%) and 51 at the acetabulum (65.38%). The pelvic fracture cases’ age and preoperative hemoglobulin levels were significantly lower (p = 0.019 and p = 0.006, respectively). When all cases were dichotomized into two groups, ones requiring ICU monitoring and the remaining, there were statistically significant differences in terms of the preoperative hemoglobin levels (p = 0.0446), intraoperative bleeding (p = 0.0134), units of erythrocyte suspension used (p = 0.0066), drain output (p = 0.0301), hospitalization duration (p = 0.0008), and the overall cost (p = 0.0002). The comparison regarding TXA use showed that the use of blood products was significantly higher in the pelvic fractures not treated with TXA (6.44 ± 4.42 units, p = 0.0029). The duration of surgery was shorter for pelvic fractures treated with TXA (98.33 ± 21.76 min, p = 0.047).ConclusionAmong the variables, the amount of intraoperative bleeding emerged as the most correlated element, which strongly suggests that in managing open reduction internal fixation surgeries performed for pelvis and acetabulum fractures, intraoperative bleeding should be considered as the crucial factor. Therefore, the administration of TXA, by effectively reducing the amount of intraoperative bleeding, should be considered as an essential tool for orthopedic surgeons.

Intravenous Tranexamic Acid for Control of Bleeding during External Dacryocystorhinostomy under General Anesthesia: A Randomized Clinical Trial.

To investigate the effect of intravenous tranexamic acid administered prior to external dacryocystorhinostomy (DCR) surgery to decrease intraoperative bleeding under general anesthesia. This was a double-blinded randomized placebo-controlled trial. A total of 70 patients (35 intervention and 35 control) with nasolacrimal duct obstruction (NLDO) who were selected for DCR surgery between September 2021 and September 2022 were included. After clinical examinations and laboratory tests, patients were randomly classified into intervention and control groups. The intervention group received 10 mg/kg intravenous tranexamic acid to a maximum dose of 1 gr 30 minutes before the surgery. Controls received normal saline solution as a placebo. The amount of intraoperative bleeding and surgical time were compared between the two groups. The intervention group included 21 men (60%) and 14 women (40%), while the control group included 19 men (54.3%) and 16 women (45.7%). The mean ages of the participants were 55.46 10.8 years and 58.06 11.28 years in the intervention and control groups, respectively. A significant difference was observed between the two groups in the surgical time analysis (control group: 37.74 9.52 minutes vs intervention: 26.03 10.5 minutes; P 0.001). Additionally, there was a significant difference in the bleeding volume between the intervention (70.66 48.19 ml) and control (47.74 60 ml) groups (P 0.001). Intravenous tranexamic acid administration before the DCR procedure can successfully control bleeding during the surgery.

To introduce a new method of resection of carotid body tumor with preservation of the internal carotid artery ----microscopic coagulation method

Objective:To introduce the surgical experience of carotid body tumor（CBT） resection with preservation of internal carotid artery. Methods:The clinical data of 109 patients with CBT were retrospectively analyzed. The key points of surgical techniques were summarized, the imaging and pathological results were comprehensively analyzed, and the postoperative complications were observed. Results:Of the 109 patients, 28 were Shamblin Ⅰ, 46 were Shamblin Ⅱ, and 35 were Shamblin Ⅲ. Synaptophysin（SYN） and soluble protein-100（S-100） were positive in all cases. There was a positive correlation between the average expression area percentage of S-100 and SYN in pathological tissue of 17 patients（r=0.48）, and the difference was statistically significant（P<0.05）. The average operation time was（148.4±46.2） minutes, the average intraoperative blood loss was（64.7±22.8） mL, and the average hospital stay was（15.2±2.6） days. Three patients underwent tumor resection combined with external carotid artery ligation, 1 patient underwent tumor resection combined with internal carotid artery ligation, and the remaining patients underwent tumor resection alone. The overall rate of intraoperative vascular ligation was 3.7% and the rate of nerve injury was 6.4%. According to preoperative CTA, intraoperative situation and postoperative pathological results, a new classification of CBT was proposed, which could intuitively reflect the gap between the tumor and the carotid artery and the nature of the tumor. Conclusion:Surgical resection of CBT is recommended after diagnosis. The potential gap between the tumor and the blood vessels was found under the microscope. Low energy bipolar electrocoagulation was used to coagulate and cut off the fibrous connective tissue between the tumor and gradually separated along the adventitia of the artery. The carotid artery could be preserved in most cases while the tumor was completely removed, and the amount of intraoperative bleeding and the incidence of complications were reduced. It is particularly important to identify the difficult cases before operation.

Effects of intraoperative different fluid therapy protocols on postoperative renal functions

PurposePlanning intraoperative fluid therapy in patients undergoing major abdominal surgery is important. It was aimed to define the difference between fluid therapy protocols for renal function, bleeding and postoperative service follow-ups.Materials and methodsThis is an observational case-controlled prospective study. Sixty patients aged 18–65 years who had undergone pancreatic surgery between December 2023– February 2023 were included in the study. Liberal (Group 1; n = 30) and targeted fluid therapies (Group 2; n = 30) were administered to the patients. Liberal fluid therapy was planned with 8–10 ml/kg/h crystalloid infusion. The targeted fluid therapy (TFT) group (Group 2; n = 30) began with a 2 ml/kg/h crystalloid infusion at the baseline. Additional fluid boluses were given in 250 ml of colloid infused over 10 min if PVI was > 13% for at least five minutes. The patients were staged using the KDIGO (Kidney Disease: Improving Global Outcomes) criteria. The amount of bleeding during surgery was recorded for both groups.ResultsNo significant difference was observed in postoperative renal function. A significant difference was observed in the amount of intraoperative bleeding. The amount of bleeding was greater in patients managed with liberal fluid therapy. No significant difference was observed between the groups in the oral intake (hour), drain withdrawal (hour) mobilization (hour) and discharge (day) times and there isn’t any statistically significant differance between groups in cost effectivity (p>0.05).ConclusionKidney function was preserved during individualized targeted fluid therapy using non-invasive haemodynamic monitoring parameters.

A Comparative Study of Trochanteric Fractures Treated with Hip Hemiarthroplasty or Proximal Femoral Nail — A Secondary Publication

Objective: The aim of this study was to compare the clinical and functional outcomes of patients treated with partial hip prosthesis (PHP) or double lag screw proximal femoral nailing (PFN) for unstable femoral intertrochanteric region fractures. Material and method: In this study, the data of 101 patients who developed grade 3-4-5 femoral intertrochanteric fractures according to the Evans-Jensen classification between 2019–2020 and were treated with cemented PHP or double screw PFN were evaluated retrospectively. The patients were evaluated in terms of postoperative follow-up time, age, gender, trauma side, American Anesthesia Society Anesthesia Risk Scale (ASA), number of comorbid diseases, total hospitalization time, amount of intraoperative bleeding, duration of surgery, and postoperative complications. Results: 101 patients evaluated within the scope of the study were divided into groups of 51 patients who underwent PHP (Group 1) and 50 patients who underwent PFN (Group 2). When the results were compared in terms of mean length of hospital stay, duration of surgery, amount of intraoperative bleeding, and postoperative 1-year mortality, the results were found to be statistically significant. Conclusion: Our study results showed that the PFN method has clinical advantages over PHP. The PFN technique is a method that can be applied quickly and safely.

Factors associated to hemoglobin decrease after percutaneous nephrolithotomy: a retrospective study.

This study aims to determine the preoperative and perioperative risk parameters associated with a decrease in hemoglobin (Hb) in patients undergoing percutaneous nephrolithotomy (PCNL). We collected prospective data of consecutive patients who underwent PCNL from January 2018 to December 2022. The median decrease in post-operative hemoglobin levels compared to pre-operative was found to be 1.5 g/dl. This value was the cut-off value that divided the sample into two groups. Group 1 has a decrease in Hb levels that is higher or equal to the cutoff, group 2 has a decrease in Hb levels that is lower than the cut-off. All preoperative, stone characteristics and perioperative factors were recorded. A total of 273 patients were included in the study, 141 in Group 1 and 132 in Group 2. The mean age of Group 1 was significantly higher (55.48 ± 8.73 vs 45.9 ± 10.75 years, p < 0.05). The mean bleeding of Group 1 was significantly higher (285.85 ± 113.68 vs 135 ± 77.54 ml, p < 0.05). There was a significant difference in mean operation time between groups (86.35 ± 32.05 vs 64.89 ± 27.83 min, p < 0.05). Multivariate analysis showed that the variables age, comorbid diabetes mellitus, intraoperative bleeding amount, and operation time had a significant relationship with Hb reduction in patients undergoing PCNL (p < 0.05). Older age, comorbid diabetes mellitus, large amounts of intraoperative bleeding, and longer operating time are factors associated with PCNL-related postoperative hemoglobin decrease.

Distal Locking of Proximal Femoral Nails in Intertrochanteric Fractures: A Comparison of Taloned and Static Locking Systems

Background: The necessity of distal locking in proximal femoral nails (PFNs) used in intertrochanteric fracture surgery is still controversial. However, the newly designed talon distalfix PFN differs from other PFN systems with its taloned distal locking (TDL) mechanism. Aim: To compare the radiologic and functional results of this newly designed TDL system and the static distal locking (SDL) system. Methods: Between January 2018 and December 2021, 142 patients over the age of 65 who underwent PFN surgery for intertrochanteric fractures in our department and underwent SDL or TDL as the distal locking mechanism were analyzed. The patients were divided into two groups as SDL and TDL according to the type of distal locking applied. Demographic variables and intraoperative data (operative time, intraoperative bleeding amount, and fluoroscopy time) were recorded. Harris hip score and Visual Analog Scale (VAS) score results were recorded to evaluate postoperative functional outcomes. Union time and all postoperative complications were recorded. Results: Of a total of 142 patients with a mean age of 77.51 ± 11.67 years, 79 underwent SDL and 63 underwent TDL. Operative time, intraoperative bleeding amount, and fluoroscopy time were significantly reduced in patients who underwent TDL compared to those who underwent SDL. The union times were found to be significantly shorter in TDL patients. There was no significant difference between the groups in terms of postoperative Harris hip score and VAS score results and complications. Conclusions: This clinical study confirms that TDL is as effective and safe as SDL. In addition, TDL has been shown to have advantages over SDL with shorter operative time, less bleeding amount, and less fluoroscopy time.

The role of using the submucosal conchoplasty technique for the management of concha bullosa in decreasing post-operative middle meatus synechia formation after functional endoscopic sinus surgery: a randomised controlled trial.

The study aimed to compare the applicability of classic lateral lamellectomy versus submucosal conchoplasty techniques in managing concha bullosa during and after functional endoscopic sinus surgery. The study randomly divided 56 patients with bilateral concha bullosa into two groups. One group of patients underwent the submucosal conchoplasty technique and the other group underwent the lateral lamellectomy technique. The study compared the intra-operative findings, including the time required for each technique, the amount of intra-operative bleeding and the post-operative endoscopic outcome of the middle meatus and middle turbinate stability. Submucosal conchoplasty was significantly more time-consuming than the lateral lamellectomy technique (p = 0.001*). The difference in the intra-operative amount of bleeding was (p = 0.086*). The lateral lamellectomy group showed a higher rate of synechia formation in the middle meatus (p = 0.012*). Submucosal conchoplasty is a valid technique for managing concha bullosa with better post-operative endoscopic outcomes.

Comparison of classical, coblation, and combined adenoidectomy techniques in paediatric patients: a single-blind, prospective study

Background and objectivesAdenoidectomy is one of the most commonly performed surgeries in pediatric otolaryngological practice. This prospective study compared three different adenoidectomy techniques' intra-operative and postoperative outcomes in pediatric patients. The techniques evaluated were classical (blind curettage), coblation, and a combined approach.Materials and methodsNinety pediatric patients undergoing adenoidectomy were enrolled in the study. The patients were divided into three groups based on the technique used: Group A, classical adenoidectomy (blind curettage); Group B, coblation adenoidectomy and Group C, combined (blind curettage + coblation) adenoidectomy. The intra-operative time, degree of bleeding, and complications during and after the operations were recorded.ResultsGroup A had a significantly shorter operative time than the other groups. However, there was no significant difference in the mean operative time between Groups B and C. The mean amount of intra-operative bleeding differed significantly among the groups. Group B had significantly less bleeding than Group A or Group C. The amount of bleeding also differed significantly between Groups A and C. The postoperative pain scores did not differ significantly among the groups. While complications were infrequent in all groups, Group C did not exhibit a higher complication rate than Groups A and B. The absence of residual or recurrent adenoid tissue in any of the groups during long-term follow-up examinations highlights the effectiveness of all three adenoidectomy techniques in preventing adenoid regrowth.ConclusionsThe combined approach, which was one of the techniques studied, demonstrated an intermediate profile in terms of operative time and intra-operative bleeding compared to the classical and coblation techniques. These findings suggest that this combined approach may be a feasible option for adenoidectomy in pediatric patients, considering its similar low incidence of postoperative complications.

Effectiveness Of Platelet Markers In Estimating The Amount Of Intraoperative Bleeding In Vertebra Surgery

AIMS: One of the most important steps in perioperative bleeding management is the predetermination of the patient at risk. Even if there is no hemostatic abnormality in vertebral surgery, which is a major surgery, severe bleeding can be encountered and many perioperative blood transfusions might be required. To date, there are no studies in the literature examining platelet markers in terms of predictivity in intraoperative bleeding during vertebral surgeries. In this study; we investigated the effectiveness of preoperative mean platelet volume (MPV), platelet distribution width (PDW), plateletcrit (PCT), mean platelet volume lymphocyte count ratio (MPVLR), and platelet count to lymphocyte count ratio (PLR) values in predicting the amount of intraoperative bleeding in patients who will undergo vertebral surgery. &#x0D; METHODS: After the approval from the ethics committee, patients who were planned for vertebral surgery by the neurosurgeon were identified. Patient demographic data such as gender, age, ASA score and body mass index (BMI), MPV, PDW, PCT, MPVLR, and PLR values were recorded. Total surgery time, the number of vertebral transpedicular screwing, and laminectomy levels performed as surgical procedures were recorded. The amount of intraoperative bleeding was determined by calculating the amount of blood accumulated in the aspirator and the amount of blood collected by the sponge during surgery. &#x0D; RESULTS: Of the 63 patients included in the study, 60.3% (n=38) were female and 39.7% (n=25) were male. The mean age of the patients was 54.7 ± 11 years and the mean BMI was 29.6 ± 4.6. No correlation was found between the amount of bleeding and gender, age, MPV, PDW, PCT, MPVLR, or PLR values. A significantly high correlation was found between amount of bleeding and BMI, duration of surgery, and the number of transpedicular screwing segments. &#x0D; CONCLUSION: Platelet markers do not appear to have an effect on the amount of bleeding. However, as the BMI increases, the duration of surgery prolongs and the number of transpedicular screw segments increases for which the amount of bleeding increases.

The "quadrant-sandwich" method in clockwise modular D2 lymph node dissection in laparoscopic total gastrectomy: a retrospective cohort study.

For patients who need laparoscopic radical gastrectomy, lymph node dissection (LND) and optimization of surgical procedures are particularly important. This study introduces the "quadrant-sandwich" method in clockwise modular D2 LND and evaluates the advantages and safety of this method. The clinical data of 108 laparoscopic total gastrectomy patients admitted to the Affiliated Cancer Hospital of Zhengzhou University from January 2019 to January 2022 were retrospectively analyzed. Based on the different LND processes, 55 patients were allocated to the observation group, which underwent clockwise modular LND using the "quadrant-sandwich method", and 53 patients were allocated to the control group, which underwent traditional LND. The effectiveness and safety of the approach in terms of operation time, blood loss, lymph node yield, postoperative recovery and postoperative complications were observed in the two groups. There was no statistical difference between the baseline data of the two groups. In relation to the surgery, the observation group had an operation time of 227.0±48.5 minutes, and intraoperative bleeding of 100.0 mL [inter-quartile range (IQR), 30.0-200.0 mL], while the control group had an operation time of 247±41.5 minutes, and intraoperative bleeding of 180.0 mL (IQR, 130.0-245.0 mL). There were statistically significant differences between the two groups in terms of the operation time and intraoperative bleeding (P=0.001, P=0.020). In relation to the LND, there were no statistically significant differences between the two groups in terms of the total number of lymph nodes in each division, and the number of positive lymph nodes. In relation to the post-operative results, there were no statistically significant differences between the two groups in terms of the post-operative pathological stage, first postoperative oral feeding, post-operative hospitalization time, and post-operative complications. Clockwise modular D2 LND using the "quadrant-sandwich method" is potentially safe and feasible in laparoscopic total gastrectomy. It not only ensures the thoroughness of the LND, but also ensures and efficient and fast surgical process, shortens the operation time, and reduces the amount of intraoperative bleeding.

Clinical efficacy of modified Kamikawa anastomosis in patients with laparoscopic proximal gastrectomy.

With the increasing incidence of proximal gastric cancer, laparoscopic proximal gastrectomy has been applied. However, reflux esophagitis often occurs after traditional esophagogastric anastomosis. In order to solve this problem, several methods of digestive tract reconstruction have emerged, but the most satisfying method remains to be discussed. Therefore, we modified traditional Kamikawa anastomosis to investigate the appropriate digestive tract reconstruction in laparoscopic proximal gastrectomy. To discuss the clinical efficacy of modified Kamikawa anastomosis in laparoscopic proximal gastrectomy. A retrospective case series was adopted. Clinicopathological data were collected from 26 patients who underwent laparoscopic proximal gastrectomy and modified Kamikawa anastomosis at our hospital from January 2020 to September 2022. The operation conditions, postoperative recovery, postoperative complications, and follow-up data were collected and analyzed. All the patients were successfully operated on without conversion to laparotomy. The duration of operation and digestive tract reconstruction were 203.500 (150-224) min and 87.500 (73-111) min, respectively. The intraoperative amount of bleeding was 20.500 mL ± 0.696 mL. The time of postoperative first flatus, the first postoperative fluid intake, and the postoperative length of stay were 2 (1-3) d, 4 (3-5) d, and 9 (8-10) d, respectively. All the patients were followed up for 12-23 months. The body mass index at 6 and 12 months after surgery were 22.577 kg/m2 ± 3.098 kg/m2 and 22.594 kg/m2 ± 3.207 kg/m2, respectively. The nutrition risk screening 2002 score, the patient-generated subjective global assessment score, and the gastroesophageal reflux disease scale score were good at 6 and 12 months after surgery. Reflux esophagitis and anastomotic stenosis were not observed in any of the patients during their 12-month postoperative gastroscopy or upper gastrointestinal tract visits. All the patients exhibited no tumor recurrence or metastasis. The modified Kamikawa anastomosis is safe and feasible for laparoscopic proximal gastrectomy and has good antireflux effects and nutritional status.

Predicting intraoperative hemorrhage during curettage treatment of cesarean scar pregnancy using free-breathing GRASP DCE-MRI

ObjectiveTo explore the feasibility of the golden-angle radial sparse parallel (GRASP) dynamic magnetic resonance imaging (MRI) technique in predicting the intraoperative bleeding risk of scar pregnancy.MethodsA total of 49 patients with cesarean scar pregnancy (CSP) who underwent curettage and GRASP-MRI imaging were retrospectively selected between January 2021 and July 2022. The pharmacokinetic parameters, including Wash-in, Wash-out, time to peck (TTP), initial area under the curve (iAUC), the transfer rate constant (Ktrans), constant flow rate (Kep), and volume of extracellular space (Ve), were calculated. The amount of intraoperative bleeding was recorded by a gynecologist who performed surgery, after which patients were divided into non-hemorrhage (blood loss ≤ 200 mL) and hemorrhage (blood loss > 200 mL) groups. The measured pharmacokinetic parameters were statistically compared using the t-test or Mann–Whitney U test with a significant level set to be p < 0.05. The receiver operating characteristic (ROC) curve was constructed, and the area under the curve (AUC) was calculated to evaluate each parameter’s capability in intraoperative hemorrhage subgroup classification.ResultsTwenty patients had intraoperative hemorrhage (blood loss > 200 mL) during curettage. The hemorrhage group had larger Wash-in, iAUC, Ktrans, Ve, and shorter TTP than the non-hemorrhage group (all P > 0.05). Wash-in had the highest AUC value (0.90), while Ktrans had the lowest value (0.67). Wash-out and Kep were not significantly different between the two groups.ConclusionGRASP DCE-MRI has the potential to forecast intraoperative hemorrhage during curettage treatment of CSP, with Wash-in exhibiting the highest predictive performance. This data holds promise for advancing personalized treatment. However, further study is required to compare its effectiveness with other risk factors identified through anatomical MRI and ultrasound.

Effectiveness of one-stage posterior eggshell osteotomy and long-segment pedicle screw fixation for ankylosing spondylitis kyphosis combined with acute thoracolumbar vertebral fracture

To explore the safety and effectiveness of one-stage posterior eggshell osteotomy and long-segment pedicle screw fixation in the treatment of ankylosing spondylitis kyphosis combined with acute thoracolumbar vertebral fracture. A clinical data of 20 patients with ankylosing spondylitis kyphosis combined with acute thoracolumbar spine fracture, who were treated with one-stage posterior eggshell osteotomy and long-segment pedicle screw fixation between April 2016 and January 2022, was retrospectively analyzed. Among them, 16 cases were male and 4 cases were female; their ages ranged from 32 to 68 years, with an average of 45.9 years. The causes of injury included 10 cases of sprain, 8 cases of fall, and 2 cases of falling from height. The time from injury to operation ranged from 1 to 12 days, with an average of 7.1 days. The injured segment was T 11 in 2 cases, T 12 in 2 cases, L 1 in 6 cases, and L 2 in 10 cases. X-ray film and CT showed that the patients had characteristic imaging manifestations of ankylosing spondylitis, and the fracture lines were involved in the anterior, middle, and posterior columns and accompanied by different degrees of kyphosis and vertebral compression; and MRI showed that 12 patients had different degrees of nerve injuries. The operation time, intraoperative bleeding, intra- and post-operative complications were recorded. The visual analogue scale (VAS) score and Oswestry disability index (ODI) were used to evaluate the low back pain and quality of life, and the American spinal cord injury association (ASIA) classification was used to evaluate the neurological function. X-ray films were taken, and local Cobb angle (LCA) and sagittal vertical axis (SVA) were measured to evaluate the correction of the kyphosis. All operations were successfully completed and the operation time ranged from 127 to 254 minutes (mean, 176.3 minutes). The amount of intraoperative bleeding ranged from 400 to 950 mL (mean, 722.5 mL). One case of dural sac tear occurred during operation, and no cerebrospinal fluid leakage occurred after repair, and the rest of the patients did not suffer from neurological and vascular injuries, cerebrospinal fluid leakage, and other related complications during operation. All incisions healed by first intention without infection or fat liquefaction. All patients were followed up 8-16 months (mean, 12.5 months). The VAS score, ODI, LCA, and SVA at 3 days after operation and last follow-up significantly improved when compared with those before operation ( P<0.05), and the difference between 3 days after operation and last follow-up was not significant ( P>0.05). The ASIA grading of neurological function at last follow-up also significantly improved when compared with that before operation ( P<0.05), including 17 cases of grade E and 3 cases of grade D. At last follow-up, all bone grafts achieved bone fusion, and no complications such as loosening, breaking of internal fixation, and pseudoarthrosis occurred. One-stage posterior eggshell osteotomy and long-segment pedicle screw fixation is an effective surgical procedure for ankylosing spondylitis kyphosis combined with acute thoracolumbar vertebral fracture. It can significantly relieve patients' clinical symptoms and to some extent, alleviate the local kyphotic deformity.

Clinical case of delivery of a pregnant woman with large uterine leiomyoma and rehabilitation in the postoperative period

Abstract. Uterine leiomyoma is a benign neoplasm of the smooth muscles of the uterus, which is one of the causes of infertility and miscarriage in women in the modern world. Delivery of pregnant women with large uterine leiomyoma is a current problem, since there is no single and clear opinion regarding the tactics of managing such patients. In the past, most specialists were inclined to perform hysterectomy after cesarean section, as they considered it the safest method of therapy, since myomectomy during cesarean section raised many questions related to complications during surgery and in the postoperative period. This article examines the modern view of specialists and the experience of the authors on organ-preserving tactics for the treatment of large uterine leiomyomas in women during pregnancy and delivery and analyzes rehabilitation in the postpartum period. The aim of the study. The aim of the study was to analyze scientific literature data on the advisability of performing myomectomy during cesarean section and combining the experience of other specialists with our own experience of delivery of pregnant woman with large uterine leiomyoma using a complex of intraoperative preventive measures. Materials and methods. A clinical case of delivery of a pregnant woman with large uterine leiomyoma and rehabilitation in the postoperative period is described. A systematic online study of articles on the topic of myomectomy during cesarean section was conducted. Results and discussion. Data from a significant number of works by other specialists indicate that preliminary substantiation of factors that may complicate surgical intervention (uterine contractility, anatomical localization, number and diameter of fibroids, as well as the presence of large vascular structures), the use of a set of preventive intraoperative measures and modern suture materials can reduce the amount of blood loss and prevent unfavorable postoperative results. Our proposed algorithm of action, including the administration of tranexamic acid before opening the anterior abdominal wall, a long-acting oxytocin agonist and the hemostatic sponge «Surgicel», allows us to minimize the amount of intraoperative bleeding and the risks of uncontrolled bleeding. It should also be noted that the addition of a cesarean section with myomectomy does not affect the course of rehabilitation in the postoperative period. Conclusions. Based on a study of literary sources over the past 10 years and our own research, we can conclude that myomectomy during cesarean section is advisable in the absence of contraindications. A combination of postoperative rehabilitation measures, tactics and techniques of surgical intervention, and prevention of intraoperative blood loss make it possible to ensure high-quality recovery for patients.

1470 nm laser is better for prostate hyperplasia treatment with different volume size via transurethral enucleation

IntroductionThe large amount of intraoperative bleeding and the high incidence of postoperative hematuria are still common factors affecting the prostate surgery treatment effect. Our research aimed to observe the effect of prostatic enucleation using 1,470 nm semiconductor laser on the amount of bleeding in patients with different sizes of prostate hyperplasia.MethodsAccording to the size of the prostate, forty eligible patients with benign prostatic hyperplasia (BPH) were enrolled and divided into low and high volume group in this study. Hemoglobin decline, urinating condition, complications and erectile function were collected and compared before and after surgery.ResultsOur data showed that hemoglobin decline was (10.0 ± 6.2) g/L and (12.1 ± 7.8) g/L, respectively for two group after surgery (P = 0.363). Urination was significantly improved following surgery in both groups of patients (P < 0.05), and no permanent urinary incontinence and sexual dysfunction and so no serious complications occurred.ConclusionThe above results suggested that prostatic enucleation using 1,470 nm semiconductor laser can be safe and effective for prostatic hyperplasia, and this surgery produced no significant effect on the amount of bleeding in whatever size of the prostate.

Safety and efficacy of high tracheostomy with inferior retraction of the thyroid isthmus

ObjectiveIn typical surgical tracheostomy, the thyroid isthmus is divided or retracted superiorly and preserved. However, at our institution, the thyroid isthmus is retracted inferiorly and preserved. Thereafter, a tracheal incision is made above the thyroid isthmus. This method, hereinafter defined as high tracheostomy, has the advantage of facilitating immediate access to the trachea in a superficial position; moreover, it can be quickly replaced with cricothyrotomy in emergency situations. However, tracheotomies placed too high can potentially damage the cricoid cartilage, thereby causing subglottic granulation and tracheal stenosis. We aimed to validate the safety and efficacy of high tracheostomy with inferior retraction of the thyroid isthmus. MethodsThis was a retrospective cohort analysis. We analyzed the operative method and other relevant characteristics of 90 patients who underwent surgical tracheostomy between April 2016 and June 2022. For those who underwent high tracheostomies, we analyzed the duration of surgery, amount of intraoperative bleeding, occurrence of complications, problems with stoma closure, and perioperative mortality. ResultsHigh tracheostomy was performed in 73 patients. Subglottic granulation occurred in one patient, and the granulation tissue spontaneously shrank. Subcutaneous emphysema occurred in two patients. No patient developed wound infection or tracheoinnominate artery fistula. Moreover, no patient experienced false route tracheotomy tube insertion because the thyroid glands were located under the stoma. ConclusionThe frequency of complications was comparable to that reported in other studies on tracheostomy. Additionally, no patient developed tracheal stenosis secondary to tracheostomy above the thyroid isthmus. Therefore, high tracheostomy with inferior retraction and preservation of the thyroid isthmus is safe and advantageous.

Three-dimensional-printed hemi-pelvic prosthesis for revision of aseptic loosening or screw fracture of modular hemi-pelvic prosthesis

To investigate the effectiveness of three-dimensional (3D)-printed hemi-pelvic prosthesis for revision of aseptic loosening or screw fracture of modular hemi-pelvic prosthesis. Between February 2017 and January 2020, 11 patients with aseptic loosening or screw fracture of modular hemi-pelvic prosthesis were revised using 3D-printed hemi-pelvic prostheses. There were 7 males and 4 females with an average age of 44 years (range, 25-60 years). In the first operation, all patients underwent total tumor resection, modular hemi-pelvic prosthesis reconstruction, and autologous femoral head transplantation. According to the Enneking pelvic partition system, 8 cases were resected in zones Ⅰ+Ⅱ and 3 cases in zones Ⅰ+Ⅱ+Ⅲ. The interval from the initial operation to this revision ranged from 14.3-66.2 months, with an average of 35.8 months. The operation time, the amount of intraoperative bleeding, and the occurrence of complications were recorded. At 6 months after the first operation, before revision, and at last follow-up, the American Musculoskeletal Tumor Society (MSTS) score and Harris score were used to evaluate the recovery of lower limb function. The pain-free walking distance of patients without brace assistance was recorded at last follow-up. X-ray films were taken at 1 month after the first operation, before revision, and at 1 month after revision, the acetabulum position was assessed by the differences in weight arm and cup height between bilateral hip joints. At last follow-up, the digital X-ray tomography was taken to evaluate the prosthesis-bone integration and the occurrence of aseptic loosening. The operation time was 182.6-238.0 minutes (mean, 197.4 minutes). The amount of intraoperative bleeding was 400-860 mL (mean, 550.0 mL). All incisions healed by first intention with no infection, hip dislocation, nerve damage, or vascular-related adverse events. The MSTS score and Harris score at last follow-up were significantly higher than those at 6 months after the first operation and before revision ( P<0.05), while the score before revision was significantly lower than that at 6 months after the first operation ( P<0.05). At last follow-up, the patients were able to walk more than 1 000 meters painlessly without brace assistance. Imaging review showed that the difference of cup height at 1 month after revision was significantly lower than that at 1 month after the first operation and before revision, and at 1 month after the first operation than before revision operation, and the differences were significant ( P<0.05). There was no significant difference in the difference of weight arm among three time points ( P>0.05). All prostheses were well integrated, and no aseptic loosening of the prosthesis or screw fracture occurred. Revision with 3D-printed hemi-pelvic prostheses benefited in reconstructing stable pelvic ring and natural bodyweight transmission for patients encountering the aseptic loosening or screw fracture of modular hemi-pelvic prosthesis. Early postoperative rehabilitation training can maximize the recovery of patient limb function, reduce pain during walking, and reduce the incidence of complications.
