Surgical Options for Retained Gallstones After Cholecystectomy.

Retained gallstones are the most common cause of postcholecystectomy pain. They may be in a long remnant cystic duct (CD), the common bile duct (CBD), or within a remnant gallbladder (GB) post subtotal cholecystectomy. Although endoscopic management is often attempted, occasionally surgical clearance is required. Rates of preoperative surgery to remove stones in a remnant GB are rising due to the increased practice of subtotal cholecystectomy during a problematic laparoscopic cholecystectomy. This study aims to review the surgical management of symptomatic retained stones at a tertiary hepatobiliary referral center in Sydney, Australia. This retrospective analysis of prospectively collected data was performed on patients who underwent an operation for retained stones after a previous cholecystectomy over 18 years (2004-2022). All of the patients with residual CBD stones had failed endoscopic retrograde cholangiopancreatogram (ERCP) attempts or could not have an ERCP because of prior foregut surgery. All patients underwent a systematic preoperative workup confirming the biliary anatomy and pathology. Fourteen patients had surgical intervention for retained stones. All cases were attempted laparoscopically and were successful in 11/14 patients (78%). Retained stones were found within a remnant GB (29%, n=4), a remnant CD (36%, n=5), or the CBD (36%, n=5). Conversion to an open procedure in 3 patients was for dense fibrosis associated with a long low-insertion of the CD, necessitating a hepatico-jejunostomy, failure to delineate the biliary anatomy, and inability to clear CBD stones, respectively. One patient developed a minor postoperative complication (superficial wound infection), and all patients were free of symptoms at a median follow-up of 33.5 months. This study demonstrates favorable outcomes in patients undergoing laparoscopic intervention for retained gallstones. A systematic approach to the workup and surgical management of patients with retained stones is essential.

A Prospective Randomized Controlled Study of Stratafix versus Standard-of-Care for Deep Tissue Closure in Orthopedic Surgery.

Orthopedic deep surgical incisions require the approximation of 1 or multiple tissue layers. This prospective randomized controlled study aimed to assess the usefulness and effectiveness of a barbed suture technique (Stratafix symmetric PDS plus) versus the conventional interrupted knotted suture technique for deep tissue closure in orthopedic surgery by comparing deep fascia suture time, relative cost, and wound-related complications. A total of 254 patients with deep surgical incisions who underwent orthopedic surgery between October 1, 2020, and June 30, 2021, were recruited. Their general characteristics (age, sex, weight, height, body mass index, American Society of Anesthesiologists physical status score, total operation time, and length of deep incision) and factors related to deep incision wounds (suture type and number, wound closure time, and operation site outcomes) were collected. The general characteristics did not differ between the Stratafix and conventional groups. There were no between-group differences observed in total operation time or total anesthesia time. The wound suture times differed significantly. In the conventional group, the suture time per unit length was lower in the group with the length of deep incision under 20 cm but did not differ significantly for each wound size. In the Stratafix group, the suture time per unit length was lower in the group under 15 cm, with the shortest time observed for 10-14.9 cm, followed by 5.0-9.9 cm and the group under 5 cm. The conventional group developed 4 cases of superficial wound infection or surgical wound necrosis. One case of protruded suture tap occurred in the Stratafix group. The average suture time per unit length increased for lengths under 5 cm as barbed sutures required more time from the start of the first suture to finish of the last suture. There was no significant benefit for very short suture length. One barbed suture material allows a suture of approximately 10-12 cm; sutures beyond that require more time because the surgeon has to start again. The Stratafix group used less suture material than the conventional group.

TROCAR SITE CLOSURE WITH OMENTAL PLUG INSERTION IN LAPAROSCOPIC BARIATRIC OPERATIONS: EFFICACY, SAFETY, AND OUTCOMES

Introduction:Trocar site herniation (TSH) remains a significant complication following laparoscopic bariatric surgery. Conventional closure techniques often prove challenging and may lead to inadequate closure, increasing the risk of TSH. This study aimed to evaluate the effectiveness and safety of a novel omental plug technique for closing trocar sites in laparoscopic bariatric surgery. Methodology:A retrospective study included 256 patients who underwent laparoscopic bariatric surgery (LSG, OAGB, or RYGB) between 2019 and 2023 at Armed Forces Hospital, Taif, Saudi Arabia. We used an innovative omental plug technique to close trocar sites ≥10mm. The primary outcome was the incidence of TSH within 12 months postoperatively, assessed clinically and with an ultrasonography examination. Secondary outcomes included wound infections, seroma formation, and reoperation for trocar site complications. Results:We observed no cases of TSH, indicating significant efficacy in preventing this complication. Other postoperative complications were minimal, with only one case (0.4%) of a superficial wound infection. Conclusion:In laparoscopic bariatric surgery, the omental plug technique demonstrated promising results in preventing TSH and reducing postoperative complications. Its ease of use, safety profile, and potential biological advantages suggest it may be a valuable alternative to traditional fascial closure methods. We warrant future larger, multicentric studies with longer follow-up to confirm these findings.

Evaluation of risk factors associated with the peritoneal flap hernioplasty for complex incisional hernia repair - a retrospective review of 327 cases

BackgroundRepair of large incisional hernias is challenging, and the risks of postoperative complications have been associated with obesity, smoking, and diabetes. The present study was conducted to determine the impact of these risk factors on short and long-term outcomes following the repair with the peritoneal flap hernioplasty (PFH).MethodsThree hundred twenty-seven patients undergoing PFH for incisional hernia repair were identified. Patient demographics and clinical data were recorded. Patients presenting signs of complications were assessed during a visit to the outpatient clinic. A multivariable regression analysis was performed to evaluate the association between BMI, smoking and diabetes, and postoperative complications.ResultsThe study included 157 males (48.0%) and 170 females (52.0%). Median BMI was 30.9 kg/m2. Diabetes was present in 13.8% of patients. 23.2% were active smokers. The recurrence rate was 2.4%. The odds ratios for postoperative complications were increased by 9% per BMI unit (P < 0.01), due predominantly to a rise in superficial wound infections (P < 0.01) and seroma production (P = 0.07). The adjusted odds ratio increased fourfold in patients with BMI > 40 kg/m2 (P = 0.06).ConclusionIncisional hernia repair with the PFH technique is associated with a low risk of short and long-term complications. The risk is associated with obesity and significantly increased in patients with a BMI exceeding 40 kg/m2, where a fourfold increase was observed predominantly due to seroma and superficial wound infections. The recurrence rate was 2.4% and was unaltered across BMI categories. No association was established between smoking, diabetes, and the risk of all-cause complications.

Simplified arthroscopic anterior talofibular ligament repair with inferior extensor retinaculum reinforcement: technical notes and preliminary results

PurposeCompared with open surgery, arthroscopic anterior talofibular ligament (ATFL) repair has many advantages and good clinical outcome. Inferior extensor retinaculum (IER) reinforcement is a supplement procedure that increase the strength of the ATFL. There is still no gold standard for arthroscopic ATFL repair. The purposes of this study were to describe a simplified technique for arthroscopic ATFL repair with IER reinforcement and to analyze its preliminary clinical results.MethodsTwenty-seven patients with chronic lateral ankle instability (CLAI) who underwent this simplified surgery were analyzed in this retrospective study. The patients’ characteristics and operative times were evaluated. Intraoperative photos, radiographs from the anterior drawer test and talar tilt test and postoperative MR images were recorded. The American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score and visual analog scale (VAS) score were also recorded. With the assistance of a needle, we performed ATFL repair and IER reinforcement with one Pushlock anchor and nonabsorbable sutures.ResultsNo complications namely skin necrosis, superficial fibular nerve injury or wound infection, were reported. The AOFAS score and VAS score improved from 64.74 ± 9.47 and 6.00 ± 1.56 to 90.74 ± 6.46 and 1.07 ± 1.09, respectively. The talar advancement and talar tilt angle were improved after surgery. One year after the operation, the ATFL appeared to be continuous on MR images.ConclusionIn this study, we proposed a simple and effective arthroscopic ATFL repair with IER reinforcement technique. The short-term follow-up examination revealed satisfactory clinical outcomes. Our technique might be a new surgical option for the treatment of CLAI.

Different surgical interventions for unstable intertrochanteric fracture of the femur: Network meta-analysis.

Although a large body of evidence has reported on surgical approaches for the treatment of unstable intertrochanteric femoral fractures, studies that comprehensively evaluate treatment outcomes are limited. The purpose of this study was to compare the effectiveness of extramedullary fixation (i.e., dynamic hip screw [DHS]), intramedullary fixation (i.e., the proximal femoral nailing [PFN]), and hemiarthroplasty (HA) for the treatment of unstable intertrochanteric femoral fractures using network meta-analysis. This study meets the preferred reporting items for systematic reviews and meta-analyses criteria. The Patient, Intervention, Comparison and Outcome search protocol framework was used to search the Google Scholar, PubMed, Embase, and Cochrane Library databases were searched from inception until June 2023. A total of 15 randomized controlled trials, including 1282 patients were analyzed. The Harris hip score (HHS) after DHS fixation was the lowest compared with that of PFN fixation and HA. DHS fixation had a significantly longer operation time than that of PFN fixation. Compared with HA, a lower incidence of superficial wound infection was observed with PFN and DHS fixations. PFN was significantly more likely to be implant cut out compared with HA. Compared with DHS, PFN and HA showed a lower incidence of fracture healing malunion. HA and PFN have good efficacy in improving the HHS and preventing joint deformities. However, HA showed a higher incidence of superficial infection than that observed with PFN, whereas a higher risk of screw cutout is observed with PFN than with HA.

ThP4.10 - Outcomes of Transcystic Laparoscopic Common Bile Duct Exploration at the time of Laparoscopic Cholecystectomy in patients with small common bile duct diameter

Abstract Aim Laparoscopic Cholecystectomy with Laparoscopic Common Bile Duct Exploration (LC+LCBDE) is a single stage therapeutic option for management of choledocholithiasis. There have been limited publications regarding the feasibility of transcystic LCBDE in patients with small (≤8mm) common bile ducts (CBD). This study seeks to examine the outcomes for patients with small ducts who underwent LC+LCBDE via a transcystic approach in a district general hospital over a two-year period. Methods Prospectively collected data regarding all patients who underwent LC+LCBDE over a period from January 2022 to December 2023 was retrospectively reviewed. Data concerning indication for surgery, CBD diameter, length of stay, complication rate, and readmission rate were determined from Electronic Care Records. Data were analysed using Microsoft Excel. Results 50 patients were identified. CBD diameter (as measured at pre-operative Magnetic Resonance Cholangiopancreatography [MRCP]) ranged from 3.5mm to 8mm (average 6.25mm). One patient required conversion to open surgery due to difficulties with the LC element of the operation. Median postoperative length of stay was 1 day (range 0-8 days) and readmission rate was 6%. One patient experienced a complication beyond Clavien-Dindo Grade 2, this caused by a superficial wound infection requiring washout under general anaesthetic. One patient required subsequent Endoscopic Retrograde Cholangiopancreatography (ERCP) for management of retained CBD stones. Conclusions LC+LCBDE is a safe and effective management option for patients in the setting of choledocholithiasis with small common bile duct diameter. Small CBD should not necessarily be a deterrent to consideration of LCBDE as a therapeutic option in appropriately selected patients.

Perforated Peptic Ulcer in Lagos. Risk Factors and Management Outcome

Abstract Background: Complications of peptic ulcers, such as bleeding, gastric outlet obstruction, and perforation, can be life-threatening and may require surgical intervention. Perforated peptic ulcer (PPU) presents mostly as a surgical emergency and is one of the leading causes of secondary peritonitis with significant morbidity and mortality. The clinical outcome of surgical treatment of peptic ulcers varies due to the varying patterns of presentations and interventions between countries. There are few documented series on PPU in Nigeria. This paper reviews the management outcome of PPU in our institution. Materials and Methods: A retrospective review of the available medical records of patients managed for PPU between February 2008 and February 2023 was conducted. All patients had a single anterior peptic ulcer perforation managed by a modified Graham’s patch. Data analysis was performed using IBM SPSS for Windows, Version 23 (IBM Corp., Armonk, NY, USA). Results: There were 107 PPU patients comprising 93 males and 14 females. The mean age of all patients was 41 years. The peak prevalence of PPU was found among patients aged 30–39 years. Delayed presentation was recorded in about half of the patients. Ingestion of non-steroidal anti-inflammatory drugs (NSAIDs) was the most common risk factor for PPU. Among the 93 documented cases, perforated gastric ulcers (71 cases) were found in a much higher proportion than duodenal ulcers (22 cases). Large ulcer (10–30 mm) was the main perforation size category found in 47 out of 83 recorded PPU cases. PPU size was not associated with the incidence of complications or mortality. The median duration of hospital stays was 13 (1–19) days. Surgical site infection was the most common complication after surgery. Conclusion: PPU is present in our predominantly male patients in their fourth decade of life. Ingestion of NSAIDs is a major risk factor. Duodenal ulcers were the predominant type seen in our patients. Documented perforated ulcer sizes in our patients are predominantly in the large category. Surgical site infection, systemic sepsis, and superficial wound infection were major complications in our patients.

Is bicortical femoral pin insertion safe for Image-based Robotic Knee Arthroplasty Surgery ? A comparative complications analysis in 970 Consecutive Cases

ObjectivesLimited data exists on complications associated with robotic image-based system in knee arthroplasty. This study aims to document complications in robotic arm-assisted knee arthroplasties, and evaluate the system’s safety by comparing two femoral pin insertion methods: bicortical diaphyseal with additional stab wounds, and unicortical metaphyseal placement through the main incision. MethodsAll patients undergoing primary knee arthroplasty with the image-based robotic system (Mako, Stryker, Mako Surgical Corp., Fort Lauderdale, FL, USA) from 1st March 2021 to 31st January 2024 with a minimum follow-up of 2 months were included. Demographics, system and non-system-related complications, as well as outcomes were recorded. Complications were categorized as either major (requiring a second surgical intervention) or minor. ResultsA total of 970 consecutive cases (median age 69.3 years) were analyzed. The unicortical group comprised 651 cases, while the bicortical group 319. The incidence of non-system-related complications was 2.37%, with the most common being joint stiffness (10 cases; 1.03%), followed by lateral femoral condyle fracture (4;0.41%). The overall incidence of system-specific complications was 1.03%. Pin-related femoral fractures occurred in 0.2% of cases, all postoperatively and in the unicortical group. There was no statistically significant difference between the femoral pin insertion-related complication rates among the two groups (0.3% in the unicortical, compared to 0% in the bicortical group; p-value= 0.3). Complications included tibia fracture (0.1%), delayed wound healing (0.2%), superficial wound infection (0.1%), tibia osteomyelitis (0.1%), and “exostosis” (0.2%). The major complications rate was 0.3% and minor 0.7%. ConclusionsMinimal system-specific overall complications indicate that robotic arm-assisted surgery is safe. The bicortical diaphyseal femoral pin insertion method does not increase the complication rates compared to the unicortical metaphyseal method. Level of evidenceIII

Mitral valve surgery in octogenarians: long-term and hemodynamic results.

Octogenarians are often denied mitral valve (MV) surgery secondary to concerns over increased perioperative morbidity and mortality. The objective of this study was to examine the outcomes of octogenarians undergoing mitral valve repair (MVr) and replacement (MVR). The outcomes of 139 patients between the ages of 80-90 who underwent MVR/MVr between 2004-2018 at the Mazankowski Alberta Heart Institute (Edmonton, AB, Canada) were retrospectively analyzed. Follow-up was extended to a maximum of 15.8 years. Following MVR, all-cause mortality at 30 days, 1 year, 5 years, 10 years, and the longest follow-up was 7%, 14%, 36.3%, 61.8%, and 67.7%, respectively. Post-MVr, all-cause mortality at the same time points was 1.9%, 7.6%, 22.5%, 55.5%, and 100%, respectively. During the Hospitalization Index, rates of new-onset atrial fibrillation, sepsis, acute kidney injury, superficial sternal wound infection, deep sternal wound infection, mediastinal bleeding, and permanent pacemaker insertion ranged from 22.1-34.0%, 3.8-11.0%, 7.6-22.0%, 1.9-2.4%, 0-1.2%, 0%, and 0-6.1%, respectively. Rates of overall rehospitalization, as well as readmission for heart failure, stroke, myocardial infarction, and MV reoperation ranged from 71.0-85.5%, 52.2-63.3%, 10.9-22.8%, 1.9-6.0%, and 0% during the follow-up period. There were significant reductions in peak MV gradient (P=0.042) and left ventricular internal diameter in diastole (LVIDd; P=0.008) post-MVR, as well as LVIDd (P<0.001) and Left Atrial (LA) Volume Index (P=0.019) post-MVr. Octogenarians exhibit positive left atrial and left ventricular remodeling following MVR. Perioperative morbidity is low, late survival is reasonable, and long-term morbidity is considerable. Overall, these results add to the growing literature that MV surgery is relatively safe and effective in octogenarians.

Olecranon fractures: An old fixation device for a new surgical technique.

Internal fixation in not-comminuted oblique and transverse olecranon fractures is commonly performed with tension band wiring. However, despite its high healing rate, this technique is associated with a high rate of complications, often requiring the removal of fixation devices in up to 80 % of cases. The aim of our study was to describe a surgical technique using eyelet pins that maintains the effectiveness of the classic tension band wiring while reducing intolerance or displacement of the fixation devices. Fifteen patients with surgically treated Mayo type II A or II B olecranon fractures, meeting the inclusion criteria, were enrolled. Clinical and functional assessments were conducted using MEPS and DASH scores at the 12 month follow-up. Additionally, complications and the duration of the operation were documented. Fifteen patients were enrolled, with eight having type II A and seven having type II B olecranon fractures. The mean patient age was 46.8 years, including ten males and five females. Nine cases involved the right side, while six involved the left. At the 12-month follow-up, the mean MEPS score was 98/100, and the DASH score was 9. Two patients (13.3 %) experienced superficial wound infections, and two (13.3 %) had persistent pain at the triceps tendon insertion site. No cases required removal of fixation devices. The eyelet pin system was found to be a safe and effective method for reducing and fixing olecranon fractures. Based on a limited series, this new technique exhibits the same reliability and reproducibility as tension band wiring but with a lower rate of complications.

Retrospective Study on Anterolateral Mini-Thoracotomy in Emergency Surgical Drainage for Massive Pericardial Effusion Including Sternotomy Case

Background: The conventional method for managing the surgical drainage of an acute massive pericardial effusion typically involves a median sternotomy. Nevertheless, advancements in surgical optics and tools have enabled the utilization of progressively smaller incisions, such as a left anterolateral thoracotomy, for the same purpose. Aim of the Study: This study aimed to assess the surgical outcomes of left anterolateral mini-thoracotomy compared to median sternotomy for draining acute massive pericardial effusion. Methods: This research took place in the Cardiac Surgery Department at Ibrahim Cardiac and Research Institute, following approval from the local ethics committee, from June 2021 to June 2023. Fourteen patients with acute massive pericardial effusion necessitating emergency surgical drainage were included. The investigation concentrated on evaluating operative and short-term postoperative results to gauge the influence of two surgical drainage methods on patients' quality of life. Result: Both groups exhibited similar age, preoperative comorbidities, and ejection fraction. The sternotomy group required more operation time than the left anterolateral mini-thoracotomy group. Furthermore, the sternotomy group had a prolonged stay in the intensive care unit and hospital compared to the left anterolateral mini-thoracotomy group. Similar rates were observed for blood transfusion and chest tube drainage. However, two cases of superficial wound infection occurred in the sternotomy group. In the anterolateral thoracotomy group, no patients required conversion to full sternotomy, and all patients were alive at the one-month follow-up after hospital discharge. Conclusion: Employing a left anterolateral mini-thoracotomy for draining acute massive pericardial effusion was deemed a secure and reliable alternative to the traditional median sternotomy incision. Despite its limited operating field, requiring proficiency, this approach preserved sternal integrity, offered a more aesthetically pleasing incision, reduced the risk of wound infection, and decreased the need for analgesia. Additionally, it was associated with a faster recovery process and a shorter stay in the intensive care unit (ICU). (Bangladesh Heart Journal 2024; 39(2): 161-167

Prognostic value of 24-hour cultivation of peritoneal fluid to distinguish complicated from uncomplicated acute appendicitis: a prospective cohort study

BackgroundThe distinction between complicated and uncomplicated acute appendicitis (AA) is important as it guides postoperative antibiotic treatment. A diagnosis based on intraoperative findings is imprecise and standard cultivation of peritoneal fluid is generally time-consuming with little clinical benefit. The aim of this study was to examine if cultivation of peritoneal fluid in acute appendicitis could reliably detect bacteria within 24 h.MethodsPatients older than 18 years undergoing laparoscopic appendectomy were prospectively enrolled at two surgical departments after informed consent was obtained. Periappendicular fluid was collected prior to appendectomy and sent for cultivation. Sensitivity, specificity and positive and negative predictive values were calculated with 95% confidence intervals (CIs) using 72-hour cultivation results as the gold standard. Patients with complicated AA as determined by the surgeon, received a three-day course of oral antibiotics. Postoperative infectious complications within 30 days after surgery were registered.ResultsFrom July 2020 to January 2021, 101 patients were included. The intraoperative diagnosis was complicated AA in 34 cases. Of these patients, six (17.6%) had bacteria cultured within 24 h after surgery, leading to a sensitivity of 60% and a specificity of 100%. The positive and negative predictive values were 1.00 and 0.96, respectively. Seven patients developed a postoperative infection (five superficial wound infections and two intra-abdominal abscess). In all cases with a positive cultivation result, the intraoperative diagnosis was complicated appendicitis and a postoperative course of antibiotics prescribed.ConclusionTwenty-four-hour cultivation of the peritoneal fluid in acute appendicitis is a valid indicator for peritoneal bacterial contamination. Randomized studies are necessary to determine if this approach is suitable for targeting postoperative antibiotic treatment as a means to prevent overtreatment without increasing the risk of infectious complications.

Functional and Radiological Outcome after Internal Fixation of Intra-articular Calcaneal Fractures.

Calcaneal fractures are rare injuries constituting 2% of all fractures. Fractures of calcaneum correspond to nearly 60-75% of the tarsal bone fractures. The calcaneum is the most commonly fractured tarsal bone 90% occur in males between 21 and 45 years of age. The calcaneal fracture may be extra-articular (sparing the subtalar joint) and intra-articular involving the subtalar joint. Intra-articular fractures account for approximately 75% of calcaneal fractures and have been associated with poor functional outcomes. In this study, we aim to assess the functional outcome of internal fixation in displaced intra-articular calcaneal fractures. A prospective interventional study was conducted on patients with only intra-articular calcaneal fractures admitted to Chettinad Hospital and Research Institute, Kelambakkam during the period from May 1, 2022, to February 29, 2024, and a total of 32 patients were considered. The functional outcome was assessed by the American Orthopaedic Foot and Ankle Society (AOFAS) Ankle Hindfoot Scoring System. The average age of the patients in our study was 39 years of which all were male. Fall from height is the most common mode of injury. The right calcaneum is more commonly involved than the left. The mean duration of hospital stay was around 10 days. The fracture classification was based on the sanders and Essex-Lopresti classification of which 17 patients were sanders type 3 and 13 patients were sanders type 2 and 1 patient was sanders type 4. The mean time for radiological union is 12 weeks. The Bohler's angle and Gissane's angle preoperatively 16.16 ± 8.87 and 121.48 ± 7.47 restored to near normal values after fixation 27.77 ± 6.02 and 113.485 ± 44, respectively. Heel height and heel width restored to near normal values of (pre-operative heel height - 24.74 ± 3.71 and heel width - 39.97 ± 4.11 and post-operative heel height - 31.55 ± 3.38 and heel width - 34.0 ± 3.1), respectively. The most common complications were wound-related complications (superficial wound infection - 9.7%, deep wound infection - 3.2%, and wound margin necrosis and wound dehiscence 6.4%) and the most common late complications were complex regional pain syndrome - 9.7% and subfibular lateral impingement with peroneal tendinitis - 6.5%. AOFAS grading of functional outcome had shown good to excellent results in 83.8% (26 patients) of the cases. The mean AOFAS score was 83.39 in our study. The present study shows that open reduction and internal fixation give superior radiographic results as shown by the restoration of Bohler's and Gissane's angle and height and width of the calcaneus to near normal values, indicating anatomical restoration of calcaneal shape. The functional outcome by AOFAS score showed good to excellent results in most of the patients with minimal wound complications.

Initial experience of SSI Mantra robot-assisted Transabdominal pre-peritoneal repair of primary ventral hernias.

Small and medium sized primary midline ventral hernias are best treated by pre-peritoneal mesh placement. This helps in prevention of complications related to intra-peritoneal mesh placement. The challenges we face while performing laparoscopic transabdominal pre-peritoneal (TAPP) procedure can be overcome by robot-assisted TAPP (rTAPP), and we present our initial experience with the same. We describe the surgical technique used in rTAPP using the relatively new SSI Mantra platform for primary midline ventral hernia repair and evaluate its feasibility and present the outcomes. we performed rTAPP for primary midline ventral hernia repair in 10 patients from July 2023 to September 2023. Demographic patient data, hernia characteristics and peri-operative outcomes were measured. A total of 10 patients underwent elective rTAPP for primary midline ventral hernia, of which 7 were male and 3 were female. The average defect size was 3.2 cm. The average operative time was 113 min. All the patients were discharged within 24-36 h after the procedure. There were no deaths. No post-operative complications such as haematoma, clinically significant seroma, deep or superficial wound infection or recurrence were noted within 30 days. rTAPP is a technically feasible procedure for the repair of small- and medium-sized midline ventral hernias with defect sizes up to 5 cm. SSI Mantra robotic platform provides the same benefit that other conventional robotic platforms provide at a much lesser cost. Further studies looking at the cost-benefit ratio are required to substantiate the above.

Is asymptomatic bacteriuria a noticeable risk factor for periprosthetic joint infection following total joint arthroplasty? A systematic review and meta-analysis.

Total joint arthroplasty (TJA) is a common procedure that improves the quality of life for severe arthritis patients. The rising demand for TJA places enormous financial strain on the world's healthcare systems, which is exacerbated by postoperative readmissions for complications such as periprosthetic joint infections (PJIs). We conducted a systematic review and meta-analysis to determine if asymptomatic bacteriuria (ASB) increases infection risk. We conducted searches in three databases: PubMed, Scopus, and Web of Science. Screening steps have been carried out according to PRISMA guidelines. The study focused on patients who had undergone TJA and exhibited ASB. Two reviewers independently screened, assessed quality, and extracted data. Meta-analysis used Mantel-Haenszel method. Following full-text screening, 12 studies were deemed eligible for inclusion in the systematic review, encompassing a total of 42,592 patients. A heightened occurrence of PJI was observed among TJA patients with ASB in comparison to controls (OR [95%CI] = 3.47 [1.42-8.44]). However, microorganisms responsible for the PJIs differed from those identified in the urine cultures of ASB. Additionally, analyses indicate that preoperative antibiotic treatment for ASB does not significantly affect the subsequent risk of PJI (OR [95% CI] = 1.00 [0.42-2.39]). Unlike surgical site infection (SSI), which did not show a difference in the rate of occurrence between the two groups, TJA patients with ASB were more likely to experience superficial wound infection (OR [95%CI] = 3.81 [2.02-7.21]). This review and meta-analysis confirm that ASB correlate with heightened risks of PJI and superficial infection in TJA patients. However, no relationship was found between ASB and PJI microorganisms which raise doubts about the role of ASB microorganisms as the direct cause of infection following TJA.

Dual Mobility Cup in Total Hip Arthroplasty

Abstract Background Proximal femoral fractures are considered a common problem in the elderly. Osteoporosis and the risk of fall especially in old age add to the complexity of management of these types of fractures. These fractures can be managed with different types of implants e.g. Dynamic hip screw, proximal femoral nail, proximal femoral plate, etc.. Aim of the Work Prospective clinical trial study to assess the role of dual mobility unconstrained acetabular components in preventing and treating instability. Patients and Methods In the period between December 2014 to April 2017 a prospective study was conducted involving 25 patients with high risk of dislocation underwent total hip replacement using dual mobility cup either as primary hip arthroplasty or revision hip arthroplasty. All cases were operated upon in Ain Shams University Hospitals and the follow up of the cases was 1 year. Results There were no cases of prosthesis dislocation or loosening. There were only two cases of superficial wound infections who improved with wound debridement. Studies showed that the dual mobility cup did a great success in reduction in the risk of dislocation in specific conditions as patients with polio and other neuromuscular disorders and other risk factors for head dislocation. Conclusion Conversion of a failed implant to a total hip implant is a good and safe option in treatment of such cases. Dual mobility cups decreased the risk of dislocation in such cases with increased longevity of the prosthesis and a considerably accepted range of motion of the hip joint.

Poster 349: Tobramycin-Soaked Grafts for the Prevention of Infection Following Anterior Cruciate Ligament Reconstruction: A Retrospective Review of Infection Rate

Objectives: Infection can be a devastating complication of anterior cruciate ligament (ACL) reconstruction. Soaking or wrapping grafts in vancomycin solution has been adopted by many surgeons to prevent infection following ACL reconstruction. Recent meta-analysis demonstrated a significant reduction in the incidence of deep infection in vancomycin-soaked grafts to be 0.09% compared to 0.74% for nontreated grafts.1 Tobramycin may provide an alternative for patients with vancomycin allergies or if vancomycin is not available. The purpose of this study is to evaluate the incidence of deep and superficial infection following ACL reconstruction in young patients with tobramycin-soaked grafts as well as characterize potential risk factors for infection. We hypothesize that tobramycin-soaked grafts result in a low deep infection rate, comparable to that of vancomycin-soaked grafts published in the literature. Methods: A total of 812 consecutive patients under age 20 who underwent ACL reconstruction at an academic medical center between 2010 and 2020 with tobramycin-soaked grafts were identified. Retrospective chart review was performed to identify postsurgical superficial and deep wound infections, as well as other pertinent surgical characteristics. The incidence of infection in this tobramycin wrap cohort was compared to the incidence of infection of vancomycin wraps as published in the literature. Results: Superficial wound infections occurred in 24 patients (2.96%) and 0 deep joint infections were identified in the tobramycin wrap cohort. The incidence of infection was 3.16% in 728 patients who received prophylactic perioperative intravenous Cefazolin and 1.23% infection incidence in 81 patients who received prophylactic perioperative Clindamycin (p = 0.30). In addition, no significant difference in incidence of superficial infection was found with patient age, sex, body mass index, or graft type. Conclusions: Tobramycin-soaked ACL grafts demonstrate a low infection risk comparable to that of vancomycin-soaked ACL grafts. The type of prophylactic IV antibiotic used in this young cohort did not impact the incidence of superficial wound infection. Further work with larger and older cohorts is needed to better characterize risk factors for postoperative infection following ACL reconstruction for all ages and comorbidities.

Paper 14: Evaluation of Outcomes at Mean 2.75 years after Repair of Lateral Meniscus Oblique Radial Tears during ACL Reconstruction

Objectives: Lateral meniscus oblique radial tears (LMORTs) commonly occur in the setting of anterior cruciate ligament (ACL) rupture. Despite publications pertaining to the prevalence, biomechanics, and surgical repair techniques of LMORTs, studies reporting outcomes following LMORT repair are lacking. The purpose of this study was to examine clinical and patient-reported outcomes following the surgical repair of LMORTs during ACL reconstruction. Methods: A retrospective chart review was conducted on 845 patients that underwent a meniscus repair at a single institution between 2017 and 2019. Operative reports, procedure notes, and operative images were manually reviewed to identify LMORTs. Subsequent knee surgery, meniscus repair failure, and postoperative complications were also extracted during the chart review. Postoperative complications were defined as reinjury, pain, stiffness, recurrent swelling, weakness, instability, or superficial wound infections. Patients were contacted postoperatively for evaluation of patient reported outcomes including the Knee Injury and Osteoarthritis Outcome Score (KOOS), Marx Activity Rating Scale (MARS), and Visual Analog Scale (VAS). Results: Twenty-five patients (68% male) were identified who underwent repair of an LMORT in the same setting as an ACL reconstruction during the study period. Mean age was 21.1 ± 4.6 years old, and the mean body mass index was 26.9 ± 5.1 kg/m2. Mean follow-up was 33.1 ± 25.7 months. There were no reported failures of the LMORT repair. Postoperative complications were reported in 9 patients (36%). Seven of these patients underwent repeat arthroscopy of the index knee for stiffness, pain, and/or repeat injury. However, of the patients who had repeat arthroscopy at the same institution (6 patients), all demonstrated complete healing of the LMORT repair site during arthroscopic evaluation. For patients completing patient-reported outcome measures, there was a minimum follow-up period of 43 months from the initial date of surgery. The mean KOOS, MARS, and VAS were 86.3 ± 8.1, 6.7 ± 4.2, and 2.0 ± 1.3, respectively. Conclusions: Surgical repair of LMORTs results in low failure risk, low complication rates, and favorable patient-reported outcome measures. Further work is needed to evaluate for differences in outcomes between meniscus repair versus partial meniscectomy versus observation of these LMORT lesions.

The Functional Outcome of Proximal Femoral Nail Antirotation-2 (PFNA-2) in Peritrochanteric Fractures of the Femur.

Introduction Peritrochanteric fractures are defined as extra-articular fractures involving the trochanter and frequent extension into the subtrochanteric region. These fractures exhibit a bimodal distribution in terms of age. These fractures commonly happen in young individuals who experience high-energy trauma, often in combination with other injuries. In contrast, elderly individuals with osteopenia are more prone to fractures caused by low-energy trauma. Methods This study is a prospective investigation that was carried out over 30 months. The study focused on peritrochanteric fractures that were treated using proximal femoral nail antirotation-2 (PFNA-2) as a fixation device. A range of criteria were examined and documented, encompassing the mean duration of surgical procedures, blood loss, the duration of hospitalization, mobility, and any potential post-operative problems. Subsequent assessments were conducted at fixed intervals of two weeks, six weeks, three months, six months, and two years. The functional outcome analysis for all patients involved the utilization of the modified Harris hip score (HHS). Results The study involved 60 cases of peritrochanteric fractures. The average age was 56 years.The most common mode of trauma was trivial fall/slip (46.66%), followed by road traffic accidents (RTA) (31.66%) and falls from height (21.66%). The average operating time was 53.03±5.66 minutes. The average modified Harris hip score was 84.78 with 26.66% excellent,70% good, and 3.33% fair results. Complications included superficial wound infection (5%), knee stiffness (11.66%), hip pain (8.33%), and shortening (1.66%). Conclusion PFNA-2 is a safe and easy implant option for treating peritrochanteric fractures as it preserves periosteal covering, minimizes blood loss, has a short operative time, and helps in early mobilization. PFNA-2 provides excellent outcomes in patients with peritrochanteric fractures with minimum complication rates compared to all other open methods and is highly recommendable.
