ThP4.7 - The outcome of a single stage Laparoendoscopic rendezvous ERCP and laparoscopic cholecystectomy for cholecystocholedocholithiasis in a DGH

Abstract Cholecystocholedocholithiasis is managed surgically by laparoscopic cholecystectomy (LC) and simultaneous common bile duct (CBD) exploration or by preoperative Endoscopic Retrograde Cholangiopancreatography (ERCP) followed by LC. Rendezvous ERCP (RERCP) is an innovative laparoendoscopic technique combining LCs and ERCPs. As a single staged procedure, a LC is performed and selective canulisation of the CBD is aided by laparoscopic transcystic placement of a guide-wire into the duodenum. We present a case series of RERCPs within a DGH. This case series collected retrospective data (2014-2023) involving 33 patients, of which 21 underwent RERCP. Preoperative variables included age, indication, gender, ASA grade, Charlson comorbidity index (CCI), frailty score and indication. Postoperative variables analysed were operating time, complications, 30-day re-admission rates and length of stay in hospital (LOSH). Of the 21 patients who underwent a RERCP, 76% (n=16) were female. The average age was 60±17years and 59% (n=13) of all procedures were elective. The ASA range was I to III, average CCI and frailty score were 2.4±1.9 and 0.1±0.4 respectively. 52% (n=11) of patients had a previous failed ERCP. The average operating time was 152±39mins. The average LOSH was 3.5±2.8days and 2.5±2.1days following the RERCP. Biliary (including pancreatitis) and non-biliary complications were 9.5% (n=2) and 9.5% (n=2) respectively. The 30-day readmission rate was 9.5% (n=2). There was no significant difference in the operating time (p=0.16), LOSH (p=0.19) complication (p=0.13) and readmission rates (p=0.50) between emergencies and elective procedures. RERCP remains a valuable option when managing cholecystocholedocholithiasis in emergency and elective settings.

Artificial urinary sphincter for neurogenic urinary incontinence: a narrative review.

The artificial urinary sphincter (AUS) is most known for its use in the treatment of moderate to severe post-prostatectomy stress urinary incontinence. However, another lesser-known indication includes stress incontinence related to intrinsic sphincter deficiency (ISD) in the neurogenic bladder population. The purpose of this review is to discuss specific technical considerations related to device implantation in this population, efficacy, durability, and complications. We performed a non-systematic literature review using the PubMed Database to identify articles specifically related to treatment of neurogenic urinary incontinence using an artificial urinary sphincter. More proximal placement of the cuff at the bladder neck is preferred in the neurogenic population due to higher rates of erosion and complications related to frequent clean intermittent catheterization or cystoscopic procedures when placed along the bulbar urethra. Robotic-assisted laparoscopic cuff placement has emerged as a safe and effective alternative to open surgery in select patients. Although continence rates are highly variable due the subjectivity of the term, functional continence (≤1 pad, ± nighttime incontinence) is reported to be between 75-90%. The need for secondary surgery for explanation with or without revision/replacement is higher in neurogenic patients compared to non-neurogenic patients. Neurogenic urinary incontinence is a complex condition due to the interplay of urethral resistance and bladder function/compliance. While there are a variety of strategies to treat neurogenic incontinence, high quality data from direct comparisons are lacking. Although AUS comes with a high revision rate, functional outcomes for continence with bladder neck placement are promising in this population.

Robotic assisted common bile duct exploration for management of complex gallstone disease.

Minimally invasive cholecystectomy and common bile duct exploration offers single- stage management for complex gallstone disease (cholelithiasis and choledocholithiasis). Robotic platform presents benefits in improving operative precision, which has not been extensively evaluated in the acute setting of managing complex gallstone disease, as well as in performing transcholedochal or post cholecystectomy common bile duct exploration. We report an early series of emergent and expedited robotic assisted cholecystectomy with common bile duct exploration (RC-CBDE) or robotic common bile duct exploration (R-CBDE) alone. Retrospective analysis from a specialist unit in the United Kingdom was undertaken from April 2022-September 2023 inclusive. All patients that underwent RC-CBDE or R-CBDE were included. Data was collated on patient demographics, perioperative investigations, intraoperative approach, and postoperative outcomes. Twenty-three consecutive patients were identified. Median (IQR) age was 51 (33-66) years. Median (IQR) Charlson Co-morbidity Index (CCI) was 1 (0-4). Five patients underwent operative intervention as an emergency and 18 on an expedited basis. Two patients underwent post cholecystectomy R-CBDE. Fourteen (61%) were transcholedochal and nine were transcystic (31%) CBDE. Median (IQR) bilirubin was 51 (34-253). Median (IQR) operative time was 176 (124-222) minutes. Median (IQR) post-operative length of stay was 2 (0-4) days. There were no bile leaks requiring intervention. The clearance rate of CBDS was 100%. No patients developed postoperative pancreatitis. One patient required intervention for port site hernia following RC-CBDE. One patient developed subhepatic collection post-operatively and required laparoscopic washout and placement of drains. No patients had retained stones after 3-month follow-up. Early experience confirms that RC-CBDE and R-CBDE in feasible, safe, and effective treatment for complex gallstone disease. Integrated adjuncts (intraoperative robotic ultrasound - IORUS and Firefly® - fluorescence guided surgery - FGS) and superior ergonomics of the robotic platform may assist in reducing the learning curve and increase wider uptake of this complex procedure.

Suture passer combined with two-hole laparoscopic peritoneal dialysis catheterization in patients undergoing peritoneal dialysis

Background Laparoscopic techniques are being widely applied for peritoneal dialysis (PD) catheter (PDC) placement. The suture passer is a novel fixation tool that aims to reduce catheter migration. We compared the clinical value of the suture passer combined with two-hole laparoscopic PDC placement to open surgical placement by evaluating preoperative and postoperative conditions, as well as the onset of complications in both groups. Methods A retrospective study was conducted including 169 patients who underwent PDC placement surgery from January 2021 to May 2023. Based on the method employed, patients were divided into two groups: the suture passer combined with a two-hole laparoscopy group (SLG) and the open surgical group (SG). Comprehensive patient information, including general data, preoperative and postoperative indicators, peritoneal function after surgery, and the incidence rate of complications, were collected and analyzed. Results The SLG showed a statistically significant decrease in operative time, intraoperative blood loss, and 6-month postoperative drift rate compared to the SG (p < 0.05). No statistically significant differences were observed between the two groups in terms of sex, age, primary disease, hospitalization time, hospitalization costs, preoperative and postoperative examination indicators, peritonitis, and omental wrapping. Conclusions Suture passer combined with two-hole laparoscopic PDC placement, characterized by simplicity and facilitating secure catheter fixation, was deemed safe and effective for patients undergoing PD. It reduces the catheter migration rate and improved surgical comfort. Overall, this technique demonstrates favorable outcomes in clinical practice.

Laparoscopic peritoneal dialysis catheter insertion with omentopexy-sparing the omentum in children.

Continuous ambulatory peritoneal dialysis is an important modality of renal replacement therapy in children. Catheter dysfunction (commonly obstruction) is a major cause of morbidity and is a significant concern that hampers renal replacement therapy. As omentum is a significant cause of obstruction, some recommend routine omentectomy during insertion of the peritoneal dialysis catheter. Omentopexy rather than omentectomy has been described in adults to spare the omentum as it may be needed as a spare part in many conditions. Laparoscopic approach is commonly preferred as it provides global evaluation of the peritoneal space, proper location of the catheteral end in the pelvis and lesser morbidity due to inherent minimally invasive nature. The aim of this study is to present the technique of laparoscopic peritoneal dialysis catheter placement in children with concurrent omentopexy. We retrospectively evaluated our patients who underwent laparoscopic placement of peritoneal dialysis catheter with concomitant omentopexy or omentectomy. A total of 30 patients were enrolled who received either omentectomy (n = 18) or omentopexy (n = 12). Four catheters were lost in the omentopexy group (33%) and 3 in the omentectomy group (17%), but none were related to omental obstruction. Three out of 4 patients in the omentopexy group and 2 out of 3 patients in the omentectomy group had a previous abdominal operation as a potential cause of catheter loss. Previous history of abdominal surgery was present in 6 patients (50%) in the omentopexy group and 3 patients (17%) in the omentectomy group. As omentum was associated with catheter failure, omentectomy is commonly recommended. Alternatively, omentopexy can be preferred in children to spare an organ that may potentially be necessary for many surgical reconstructive procedures in the future. Laparoscopic peritoneal dialysis catheter placement with concomitant omentopexy appears as a feasable and reproducible technique. Although the catheter loss seems to be higher in the omentopexy group, none was related with the omentopexy procedure and may be related to the higher rate of history of previous abdominal operations in this group.

Single-port plus one in pediatric robotic-assisted Lich-Gregoir ureteral reimplantation for vesicoureteral reflux, a comparative analysis with short-term outcomes

ObjectiveTo observe the safety and short-term outcomes of a new way of laparoscopic trocar placement in pediatric robotic-assisted Lich-Gregoir ureteral reimplantation for vesicoureteral reflux.MethodsThe retrospective study included 32 patients under 14 years diagnosed with primary vesicoureteral reflux (VUR). All these patients underwent robotic-assisted Lich-Gregoir ureteral reimplantation in our department from December 2020 to August 2022. These patients were divided into the following groups according to the different ways of trocar placement: 13 patients in group single-port plus one (SR) and 19 patients in group multiple-port (MR). Patients’ characteristics as well as their perioperative and follow-up data were collected and evaluated.ResultsThere was no significant difference in the data regarding patients’ characteristics and preoperative data. These data included the grade of vesicoureteral reflux according to the voiding cystourethrogram (VCUG), and the differential degree of renal function (DRF) at the following time points: preoperative, postoperative, and comparison of preoperative and postoperative. There was no difference between the two groups. During surgery, the time of artificial pneumoperitoneum establishment, ureteral reimplantation time, and total operative time in the SR group were longer than those in the MR group. Yet only the time of artificial pneumoperitoneum establishment shows a statistical difference (P < 0.0001). Also, the peri-operative data, including the volume of blood loss, fasting time, hospitalization, and length of time that a ureteral catheter remained in place, and the number of postoperative complications demonstrate no difference. In addition, the SFU grade and VCUG grade at the following time point also show no difference between the two groups.ConclusionThe study demonstrates that SR in robotic-assisted Lich-Gregoir ureteral reimplantation has reached the same surgical effects as MR. In addition, the single-port plus one trocar placement receives a higher cosmetic satisfaction score from parents and did not increase the surgical time and complexity.

Gallbladder sinistroposition (left-sided) finding in laparoscopic cholecystectomy, a case report

A left-sided gallbladder (LSGB), also known as sinistropostition, is a rare anatomical variant with a reported incidence of 0.2-1.1%. It is defined as a gallbladder located on the left side of the falciform ligament, embedded in the third hepatic lobe, without situs inversus viscerum. A 37-year-old Latino man with a history of bilateral inguinal repair underwent a scheduled laparoscopic cholecystectomy due to multiple gallbladder polyps. Preoperative ultrasound reported a gallbladder of 60x20 mm, wall thickness of 1 mm, with polyps of up to 10 mm. Standard laparoscopic cholecystectomy trocar placement was used. Upon revision of the right hepatic lobe, there was an absence of the GB in the visceral side of segments IV, V, or VI. It was identified to the left of the falciform ligament with adhesions to the anterior and superior portions of the pylorus and lesser curvature. The subxiphoid trocar was adjusted to the left of the falciform ligament, and Calot’s triangle dissection was performed to obtain a critical view of safety. No other anatomical variants were identified. The procedure was performed safely with a satisfactory view of critical cholecystectomy steps and anatomy identification. After the procedure, the surgeon complained of right-hand pain and numbness due to a medial position of the subxiphoid trocar for dissection. The surgical approach of a LSGB in laparoscopic surgery should be individualized for each patient. A minimally invasive approach may be realized successfully when critical thinking by the surgeon is applied and always prioritizing the safety of the patient.

Laparoscopic polyglycolic acid spacer placement for locally recurrent rectal cancer.

Carbon ion radiotherapy (CIRT) has received attention for the treatment of locally recurrent rectal cancer. When the surrounding primary organs are close to the irradiation site, a spacer is required to ensure safe irradiation. This work describes a novel technique using a bioabsorbable polyglycolic acid spacer placed laparoscopically and presents a technical report with five case studies. The short-term surgical outcomes were as follows: mean operating time 235 min with blood loss of 38 mL. CIRT was planned, and the patients underwent irradiation within 2 months of surgery. No pelvic infections occurred, and all procedures were performed safely. Herein, were present a technical report with reference to a video of the surgical procedure.

Patient-Reported Outcomes for Robot-Assisted Laparoscopic Extravascular Renal Vein Stent Placements for Nutcracker Syndrome.

Introduction: Nutcracker phenomenon is the compression of the left renal vein between the superior mesenteric artery (SMA) and the abdominal aorta. Nutcracker syndrome refers to the presence of nutcracker phenomenon with symptoms. Between 2016 and 2022, we performed 18 robot-assisted laparoscopic extravascular renal vein stent (RALERVS) placements. We sought to assess patient-reported outcomes of RALERVS placement by a single institution. Methods: We performed a single-center retrospective review of 18 patients with a minimum of 3 months follow-up. Symptoms were assessed utilizing a questionnaire conducted with a 5-point Likert scale at a minimum of 3 months postoperatively. Five on the Likert scale was severe while 1 was none. Primary study outcomes compared pre- and postoperative patient-reported symptom scores. Results: Twelve out of 18 patients responded to the survey. The average length of time from date of operation to completion of survey was 2.6 years. Average age of the cohort was 36 years with a mean BMI of 19.4 kg/m2. There was only one man. Mean operative time was 137 minutes and mean estimated blood loss was 12 mL. Mean preoperative SMA angle was 19° and mean postoperative SMA angle was 36°. Patients reported that flank pain, abdominal pain, nausea, headaches, back pain, pelvic pain, and early satiety improved (p < 0.05). Ten of 12 respondents would recommend RALERVS for nutcracker syndrome. Conclusion: RALERVS demonstrates an effective treatment for nutcracker syndrome. Patients reported improved symptoms at 3 months postoperatively across multiple domains. Further studies need to be conducted to assess long-term durability of the extravascular renal vein graft.

Favorable surgical and obstetrical outcomes in pre- and postconceptional laparoscopic abdominal cerclage: a large multicenter cohort study

BackgroundCervical incompetence is an important cause of extreme preterm delivery. Without specialized treatment, cervical incompetence has a 30% chance of recurrence in a subsequent pregnancy. Recently the first randomized controlled trial showed significant superiority of the abdominal cerclage compared to both a high and low vaginal cerclage in preventing preterm delivery <32 weeks of gestational age and fetal loss in patients with a prior failed vaginal cerclage. Objective(s)To assess surgical and obstetric outcomes in patients with pre- and postconceptional laparoscopic abdominal cerclage placement. Furthermore, to perform subgroup analysis based on the indication for cerclage placement in order to identify patients that benefit the most from an abdominal cerclage. Study designA retrospective multicenter cohort study with consecutive inclusion of all eligible patients from 1997 onwards in the Dutch cohort (104 patients) and from 2007 onwards in the Boston cohort (169 patients) was conducted. Eligible patients suffered from at least one second- or third-trimester fetal loss because of cervical incompetence and/or a short or absent cervix after cervical surgery. This includes loop electrosurgical excision procedure (LEEP), conization or trachelectomy. Patients were divided into subgroups based on the indication for cerclage placement: 1) prior failed vaginal cerclage 2) prior cervical surgery 3) other indications. This third group consisted of patients with a history of multiple second- or early third-trimester fetal losses based on cervical incompetence (without a failed vaginal cerclage) and/or multiple dilation and curettage procedures. The primary outcome measure was delivery at ≥34 weeks of gestation with neonatal survival at hospital discharge. Secondary outcome measures included surgical and obstetric outcomes, such as pregnancy rates after preconceptional surgery, obstetric complications and fetal survival rates. ResultsA total of 273 patients were included; 250 patients in the preconceptional cohort and 23 patients in the postconceptional cohort. Surgical outcomes of 273 patients were favorable with six minor complications (2.2%). In the postconceptional cohort we had one patient (0.4%) with hemorrhage of 650 ml, resulting in conversion to laparotomy. After preconceptional laparoscopic abdominal cerclage (n=250) the pregnancy rate was 74.1% (n=137) with a minimal follow-up of 12 months. Delivery at ≥ 34 weeks of gestation occurred in 90.5% of all ongoing pregnancies. Four patients (3.3%) suffered from a second-trimester fetal loss. The indication for the cerclage in all four patients was a prior failed vaginal cerclage. The other subgroups showed fetal survival rates of 100% in ongoing pregnancies with a total fetal survival rate of 96%. After postconceptional placement, 94.1% of all patients with an ongoing pregnancy delivered at ≥ 34 weeks of gestation with a total fetal survival rate of 100%. Thus second-trimester fetal losses did not occur in this group. Conclusion(s)Pre- and postconceptional laparoscopic abdominal cerclage is a safe procedure with favorable obstetric outcomes in patients with an increased risk of cervical incompetence. All subgroups show high fetal survival rates. Second-trimester fetal loss only occurred in the group of patients with a cerclage placed for the indication prior failed vaginal cerclage, but also in this group the chance was low.

Advanced Image-Guided Percutaneous Technique Versus Advanced Laparoscopic Surgical Technique for Peritoneal Dialysis Catheter Placement

Timely placement of a functional peritoneal dialysis (PD) catheter is crucial to long-term PD success. Advanced image-guided percutaneous and advanced laparoscopic techniques both represent best practice catheter placement options. Advanced image-guided percutaneous is a minimally invasive procedure that does not require general anesthesia. Retrospective cohort study comparing time from referral to procedure, complication rate, and 1-year catheter survival between placement techniques. Patients who had advanced laparoscopic or advanced image-guided percutaneous PD catheter placement from January 1, 2011 to December 31, 2013 in an integrated Northern California health care delivery system. PD catheter placement using advanced laparoscopic or advanced image-guided percutaneous techniques. One-year PD catheter survival; major, minor, and infectious complications; time from referral to PD catheter placement; and procedure time. Wilcoxon rank sum tests to compare referral and procedure times; χ2/Fisher exact tests to compare complications; and modified least-squares regression to compare adjusted 1-year catheter survival between PD placement techniques. We identified 191 and 238 PD catheters placed through advanced image-guided percutaneous and advanced laparoscopic techniques, respectively. Adjusted 1-year PD catheter survival was 80% (95% CI, 74%-87%) using advanced image-guided percutaneous technique vs 91% (87%-96%) using advanced laparoscopic technique (P=0.01). Major complications were<1% in both groups. Minor and infectious complications were 45.6% and 38.7% in advanced image-guided percutaneous and advanced laparoscopic techniques, respectively (P=0.01). Median days from referral to procedure were 12 and 33 for patients undergoing advanced image-guided percutaneous and advanced laparoscopic techniques, respectively (P<0.001). Median procedure time was 30 and 44.5 minutes for patients undergoing advanced image-guided percutaneous and advanced laparoscopic techniques, respectively (P<0.001). Retrospective study with practice preference influenced by timing, local expertise, and resources. Both advanced image-guided percutaneous and advanced laparoscopic techniques reported rare major complications and demonstrated excellent (advanced laparoscopic) and acceptable (advanced image-guided percutaneous) 1-year PD catheter survival. For patients referred for PD catheter placement at centers where advanced laparoscopic resources or expertise remain limited, the advanced image-guided percutaneous technique can provide a complementary and timely option to support the utilization of PD. Peritoneal dialysis is a preferred dialysis modality for many patients. However, the lack of available skilled surgeons can limit the placement of the peritoneal dialysis catheter in a timely manner. In the past decade, interventional radiology has developed expertise in placing peritoneal dialysis catheters. Using data from an integrated health care system, we compared the outcome of peritoneal dialysis catheters placed using laparoscopic surgery and interventional radiology techniques. Our results showed excellent 1-year patency of peritoneal dialysis catheters placed using laparoscopic surgery, whereas interventional radiology placement of catheters had lower but acceptable1-year patency survival, based on best practice guideline criteria. Hence, interventional radiology placement of peritoneal dialysis catheters may be a viable alternative when laparoscopic surgery is not available or feasible.

Laparoscopic Inguinal Hernia Repair and Synchronous Peritoneal Dialysis Catheter Placement: A Single-Center Experience.

Background: Peritoneal dialysis (PD) is a common method for treating end-stage renal disease (ESRD). Occurrence of inguinal hernia before and during PD is considered to be the main cause of treatment discontinuation, failure, and conversion to hemodialysis. In this study, we present a single-center experience about laparoscopic inguinal hernia repair and synchronous PD catheter placement and evaluated the feasibility and outcomes. Methods: During May 2018 to May 2022, a total of 216 consecutive patients with ESRD underwent laparoscopic PD catheter placement. Among them, 41 patients (27.7%) with coexistent inguinal hernia were included in this study. Individual information, complications, recurrent and new-onset hernias, and catheter survival were retrospectively analyzed. Results: Forty-one patients underwent laparoscopic inguinal hernia repair and synchronous PD catheter placement, 9 patients had bilateral inguinal hernia, and another 32 patients had unilateral inguinal hernia. The mean age was 46.49 years (range, 28-72 years), including 39 males and 2 females. There was no recurrent hernia and only 1 patient (2.4%) developed incisional hernia (trocar site hernia) which required hernia repair and discontinuation of PD. No postoperative complications were observed, such as bleeding, infection, and dialysate leakage. After a median follow-up of 37 months (20-58 months), there were no deaths and 97.6% (40/41) catheters were still working. Conclusions: Laparoscopic hernia repair and synchronous PD catheter placement is an effective and safe treatment for ESRD patients with coexisting inguinal hernia in virtue of low postoperative complications and high catheter survival.

Modified Single Port Laparoscopic Peritoneal Dialysis Catheter Insertion - Initial Experience and Outcome from a Tertiary Care Centre

Background: Chronic kidney disease (CKD) and end-stage renal disease (ESRD) are emerging as a major health related issues in developing countries. The increasing numbers require rapid adaptation of existing health-care policies. The number of patients requiring renal care is only bound to increase in coming years with the increasing incidence and prevalence of diabetes. Continuous ambulatory peritoneal dialysis (CAPD) catheter placement is performed on end-stage renal disease (ESRD) patients. There is abundant literature regarding post-operative outcomes and re-operative rates following CAPD. We report our initial experience of modified single port laparoscopic technique of placing CAPD catheters using a single port through the Palmer’s point and discuss our surgical outcomes. Methods: This was a retrospective review (2019-2020) of patients undergoing CAPD catheter placement at SMVD Narayana Superspecialty Hospital. Outcome analysis focused on patient related outcomes, including early (&lt; 30 days) versus late (≥ 30 days) complication and re-operation rates. Results: A total of 30 patients with ESRD, (mean ASA score = 3.3) were included in the study who underwent modified single port laparoscopic (n = 30) CAPD catheter placement (mean follow-up = 180 days). The total complication rate with the procedure was 43%, with re-operation rate of 20%. CAPD catheter non-function occurred in 06 patients (20% of total). CAPD catheter migrations occurred in 03 patients (10% of total). CAPD catheter related infections occurred in 05 patients (16% of total), and 02 required re-operation; 03 patients were treated successfully with culture directed antibiotics. There were 2 deaths during the study period, one due to peritonitis and other due to underlying cardiac disease. There was no surgical mortality in the study group. Conclusion: Although CAPD catheter placement in patients with ESRD are technically un-complicated to accomplish, long term results suggest as many as one in three patients will struggle with some form of catheter malfunction or infection. Our modified technique and the results have led to changes in our CAPD catheter placement technique, as well as the post-operative patient care algorithm.

How Many Operative Performance Ratings Does a Pediatric Surgery Fellow Need to Be Deemed Practice Ready?

PurposeIdentifying the number of cases required for a fellow to achieve competence has been challenging. Workplace-based assessment (WBA) systems make collecting performance data practical and create the opportunity to translate WBA ratings into probabilistic statements about a fellow's likelihood of performing to a given standard on a subsequent assessment opportunity. MethodsWe compared data from two pediatric surgery training programs that used the performance rating scale from the Society for Improving Medical Professional Learning (SIMPL). We used a Bayesian generalized linear mixed effects model to examine the relationship past and future performance for three procedures: Laparoscopic Inguinal Hernia Repair, Laparoscopic Gastrostomy Tube Placement, and Pyloromyotomy. ResultsFor site one, 26 faculty assessed 9 fellows on 16 procedures yielding 1094 ratings, of which 778 (71%) earned practice-ready ratings. For site two, 25 faculty rated 3 fellows on 4 unique procedures yielding 234 ratings of which 151 (65%) were deemed practice-ready. We identified similar model-based future performance expectations, with prior practice-ready ratings having a similar average effect across both sites (Site one, B = 0.25; Site two, B = 0.25). Similar prior practice-ready ratings were needed for Laparoscopic G-Tube Placement (Site one = 13; Site two = 14), while greater differences were observed for Laparoscopic Inguinal Hernia Repair (Site one = 10; Site two = 15) and Pyloromyotomy (Site one = 10; Site two = 15). ConclusionOur approach to modeling operative performance data is effective at determining future practice readiness of pediatric surgery fellows across multiple faculty and fellow groups. This method could be used to establish minimum case number requirements. Type of StudyOriginal manuscript, Study of Diagnostic Test. Level of EvidenceII.

#6297 LAPAROSCOPIC VERSUS OPEN-SURGERY CATHETER PLACEMENT IN PERITONEAL DIALYSIS PATIENTS: A META-ANALYSIS OF OUTCOMES

Abstract Background and Aims The peritoneal dialysis catheter (PDC) can be placed either through the laparoscopic technique, percutaneous technique or surgical procedures. The utilization of these PDC placement procedures is based on successful placement and reduced risk of development of complications. The main objective of this study was to compare the complications associated with laparoscopic vs. open-surgery PDC placement procedure. Method Literature for this review was obtained from all databases. to studies published in the period between 1998 and 2019 using Stata Version 12. Results The results showed significant difference in catheter malfunction between the laparoscopic and open-surgery group (relative risk [RR] = 0.58; 95% CI: 0.42–0.8; P = 0.031). Furthermore, there was no significant statistical difference in dialysate leakage (RR = 0.77; 95% CI: 0.51–1.17, P = 0.116) peritonitis (RR = 0.8; 95% CI: 0.6–1.06, P = 0.349) and exit-site infection (RR = 0.84; 95% CI: 0.65–1.09, P = 0.834) between the laparoscopic and open-surgery PDC placement groups. Conclusion The laparoscopic PDC placement procedure was superior to open surgery in regards to catheter malfunction. Additionally, the choice of treatment procedure should put in consideration factors such as cost and comfortability of the patient.

MRI enhances the understanding of critical anatomy during primary laparoscopic port placement.

Despite the majority of laparoscopic visceral injuries occurring with primary entry, high-fidelity training models are lacking. Three healthy volunteers underwent non-contrast 3T MRI at Edinburgh Imaging. A direct entry 12mm trocar was filled with water to improve MR visibility, placed on the skin at entry points, then images were acquired in the supine position. Composite images were created, and distances from the trocar tip to the viscera were measured, demonstrating anatomical relationships during laparoscopic entry. With a BMI of 21 kg/m2, gentle downward pressure during skin incision or trocar entry reduced the distance to the aorta to less than the length of a No. 11 Scalpel blade (22mm). The need for counter-traction and stabilisation of the abdominal wall during incision and entry is demonstrated. With a BMI of 38 kg/m2, deviating from the vertical angle for trocar insertion can result in the entire trocar shaft being placed within the abdominal wall without entering the peritoneum, creating a 'failed entry.' At Palmer's point distance between the skin and bowel is only 20mm. Ensuring the stomach is not distended will minimise gastric injury risk. The use of MRI to provide visualisation of the critical anatomy during primary port entry allows the surgeon to gain better understanding of textually described best practice techniques.

Peritoneal Dialysis Catheter Placement in Children: Initial Experience with a "2+1"-Port Laparoscopic-Assisted Technique.

We assessed a cohort of five children who underwent laparoscopic-assisted PDC placement between 2018 and 2022. This procedure is a simple, relatively quick, and safe technique for PDC placement. Furthermore, in our experience, concomitant omentectomy is necessary to reduce the risk of catheter obstruction and migration due to omental wrapping. The laparoscopic approach allows for improved visualization and more accurate placement of a catheter inside the abdominal cavity. Concomitant omental excision is necessary to prevent PDC malfunction and migration.
