Mirizzi Syndrome-The Past, Present, and Future.

Mirizzi syndrome is a complication of gallstone disease caused by an impacted gallstone in the infundibulum of the gallbladder or within the cystic duct, causing chronic inflammation and extrinsic compression of the common hepatic duct or common bile duct. Eventually, mucosal ulceration occurs and progresses to cholecystobiliary fistulation. Numerous systems exist to classify Mirizzi syndrome, with the Csendes classification widely adopted. It describes five types of Mirizzi syndrome according to the presence of a cholecystobiliary fistula and its corresponding severity, and whether a cholecystoenteric fistula is present. The clinical presentation of Mirizzi syndrome is non-specific, and patients typically have a longstanding history of gallstones. It commonly presents with obstructive jaundice, and can mimic gallbladder, biliary, or pancreatic malignancy. Achieving a preoperative diagnosis guides surgical planning and improves treatment outcomes. However, a significant proportion of cases of Mirizzi syndrome are diagnosed intraoperatively, and the presence of dense adhesions and distorted anatomy at Calot's triangle increases the risk of bile duct injury. Cholecystectomy remains the mainstay of treatment for Mirizzi syndrome, and laparoscopic cholecystectomy is increasingly becoming a viable option, especially for less severe stages of cholecystobiliary fistula. Subtotal cholecystectomy is feasible if total cholecystectomy cannot be performed safely. Additional procedures may be required, such as common bile duct exploration, choledochoplasty, and bilioenteric anastomosis. Conclusions: There is currently no consensus for the management of Mirizzi syndrome, as the management options depend on the extent of surgical pathology and availability of surgical expertise. Multidisciplinary collaboration is important to achieve diagnostic accuracy and guide treatment planning to ensure good clinical outcomes.

Parenchyma Sparing Anatomic Liver Resections (Bi- and Uni-Segmentectomies) for Liver Tumours in Children-A Single-Centre Experience.

This study included 23 patients that underwent (bi)segmentectomy. There were 15 malignant tumours (hepatoblastoma-13 patients), 7 benign tumours, and 1 calcifying nested stromal epithelial tumour. The median tumour diameter was 52 mm (range 15-170 mm). Bisegmentectomy 2-3 was most frequently performed (seven patients), followed by bisegmentectomy 5-6 (four patients). The median operative time was 225 min (range 95-643 min). Intraoperative complications occurred in two patients-small bowel perforation in one and an injury of the small peripheral bile duct resulting in biloma in the other. The median resection margin in patients with hepatoblastoma was 3 mm (range 1-15 mm). Microscopically negative margin status was achieved in 12 out of 13 patients. There were two recurrences. After a median follow-up time of 38 months (range 12-144 months), all 13 patients with HB were alive with no evidence of disease. Two relapsed patients were alive with no evidence of disease. From the available literature and data presented here, we propose that (bi)segmentectomy can become a viable surgical option in carefully selected paediatric patients and is sufficient to achieve a cure. Further studies evaluating the impact of parenchymal preservation surgery on surgical and oncological outcome should be conducted with a larger dataset.

Elevated serum IL-34 is correlated with disease severity in patients with biliary atresia following Kasai portoenterostomy

BackgroundBiliary atresia (BA) is a severe congenital disorder with progressive obstructive cholangiopathy in young children. The inflammatory process has been recognized as one of the pathological mechanisms driving bile duct injury. Since interleukin-34 (IL-34) has been reportedly linked to several pathological liver disorders, including inflammation, the current study aimed to analyze circulating IL-34 and the association of circulating IL-34 with hepatic deterioration and clinical outcomes in post-Kasai BA children. MethodsCirculating IL-34 levels were analyzed in 89 post-Kasai BA subjects and 45 healthy individuals using an ELISA. Liver stiffness (hardness) was measured by ultrasound elastography. ResultsCirculating IL-34 was substantially higher in BA children than in control individuals, particularly those with unfavorable outcomes including hepatic dysfunction, jaundice, and portal hypertension. In BA group, circulating IL-34 was positively correlated with liver stiffness (r = 0.515, p < 0.001), AST (r = 0.403, p < 0.001), ALT (r = 0.279, p = 0.008), total bilirubin (r = 0.224, p = 0.03), ALP (r = 0.255, p = 0.016), and serum IL-6 (r = 0.590, p < 0.001) but inversely correlated with albumin (r = -0.417, p < 0.001). Kaplan-Meier survival analysis showed that higher circulating IL-34 levels were significantly associated with reduced survival rates in BA subjects (p = 0.002). ConclusionHigher circulating IL-34 values were directly associated with hepatic impairment and the BA severity, implicating thatserum IL-34 could be applied as a noninvasive marker for the monitoring of the severity in BA subjects following Kasai portoenterostomy and therapeutic efficacy.

Laparoscopic Cholecystectomy in Jos: Prospects and Perspectives.

Laparoscopic cholecystectomy is now done in a lot more private and public hospital settings presently in low-income countries, particularly sub-Saharan Africa. Though it is not routinely done in these centres, the percentage of cholecystectomies done laparoscopically has increased over the years. Laparoscopic surgery services were introduced at our hospital in 2011 and this retrospective study reviews our outcomes with the procedure over a 6-year period. A total of 87 cholecystectomies were done in the period under review. Forty-eight (55.2%) were laparoscopic cholecystectomies, 30 (44.8%) were open cholecystectomies, and 9 (10.3%) were mini-laparotomy cholecystectomies. There were 32 (66.7%) women and 16 (33.3%) men who had laparoscopic cholecystectomy giving a male-to-female ratio of 1:2. The mean age of the patients was 41.0 years (SD = 14.3 years). The most common indication for laparoscopic cholecystectomy was calculous cholecystitis. The most common co-morbidity was hypertension in 23 (47.9%) patients, followed by sickle cell anaemia in 10 (20.8%) patients. The operating time ranged from 70 min to 120 min with a mean of 86.6 (SD = 14.5). There were three conversions and two intra-operative complications. Twenty-five patients (52.1%) were discharged within 24 h, 16 (33.3%) within 48 h and the rest (14.6%) were discharged later. The duration of surgery had a significant association with duration of hospital stay. There was 1 mortality in our study. Laparoscopic cholecystectomy offers unique advantages over open such as decreased length of hospital stay and reduced wound complications. Most of the cholecystectomies in our setting are now performed laparoscopically with a low conversion rate and low incidence of bile duct injuries. Patients with sickle cell disease constitute a significant percentage of patients requiring this procedure.

The robotic-assisted laparoscopic approach to biliary tract resection and reconstruction for benign indications: A single-center experience.

Benign biliary disease (BBD) is a prevalent condition involving patients who require extrahepatic bile duct resections and reconstructions due to nonmalignant causes. This study followed all patients who underwent biliary resections for BBD between 2015 and 2023. We excluded those with malignant conditions and patients who had an 'open' operation. Based on the patient's anatomy, the procedures employed were either robotic Roux-en-Y hepaticojejunostomy (RYHJ) or robotic choledochoduodenostomy (CDD). From the 33 patients studied, 23 were female, and 10 were male. Anesthesiology (ASA) class was 3±0.5; the MELD score was 9±4.1; the Child-Pugh score was 6±1.7. The primary indications for undergoing the operation included iatrogenic bile duct injuries, biliary strictures, and type 1 choledochal cysts. The average surgical duration was about 272min, and the average blood loss amounted to 79mL. Postoperatively, three patients experienced major complications, all attributed to anastomotic leaks. The average hospital stay was 4days, with a readmission rate of 15% within 30days. During an average follow-up period of 33months, one patient had to undergo a revision at 18months due to stricture. This necessitated further duct resection and reanastomosis. Notably, there were no reported hepatectomies, no conversion to the 'open' method, no intraoperative complications, and no mortalities. Robotic extrahepatic bile duct resection and reconstruction with Roux-en-Y hepaticojejunostomy or choledochoduodenostomy is safe with an acceptable postoperative morbidity, short hospital length of stay, and low postoperative stricture rate at intermediate duration follow-up.

Differentiated approach in providing care to patients with fresh bile duct injuries

Aim. To demonstrate the efficacy of minimally invasive surgery for bile duct injuries.Materials and methods. The results of combined minimally invasive treatment of 52 patients with fresh bile duct injuries from 2006 to 2023 were analyzed. Bile duct injuries diagnosed within 1–10 days after the operation were referred to as “fresh”. Intraoperative detection of bile duct injury was the criterion of exclusion from the analysis. In 80.8% of observations, combined minimally invasive interventions were performed in the form of percutaneous operations under ultrasound and radiography control. In 19.2% of observations, antegrade percutaneous and retrograde endoscopic access was used.Results. The algorithm for conducting minimally invasive procedures for bile duct injuries and strictures should be selected depending on the terms of injury and the character of injury and complications. In the majority of fresh bile duct injuries, a two-stage algorithm of duct patency restoration was applied. This prevented additional complications and allowed the patient to be prepared for stent biliary drainage after analyzing the primary data of fistula cholangiography. In all observations, minimally invasive procedures of bile duct patency restoration were completed with stent biliary drainage. Complications were noted in eight patients (15.4%).Conclusion. In fresh bile duct injuries, combined minimally invasive methods are an effective alternative to conventional reconstructive surgeries.

Audit of Emergency Laparoscopic Cholecystectomy in a District General Hospital.

Introduction Acute gallstone diseases are common surgical emergencies, accounting for approximately one-third of emergency surgical admissions. Laparoscopic cholecystectomy is thestandard choice of treatment for gallstone diseases and is currently one of the most commonly performed surgical procedures in the United Kingdom.Majority of these procedures are carried out as elective cases. National Institute of Clinical Excellence (NICE) guidelines and other upper gastrointestinal surgery specialty bodies encourage early emergency surgery inacute symptomatic gallstone disease. Weassessed emergency laparoscopic cholecystectomiesperformed at Birmingham Heartlands Hospital, United Kingdom andcompared the practice against NICE and British Benign Upper Gastrointestinal Surgery Society (BBUGSS) recommendations. Methods This is a snapshot retrospective audit, assessing emergency laparoscopic cholecystectomy practice over a nine-month periodfrom November 2022 to July 2023.Variables assessed were demographics, duration of symptoms prior to surgery, imaging modality, indications, C-reactive protein (CRP) levels, operative difficulty, intraoperative and postoperative complications, length of hospital stay and readmission rates. These variables were compared against both NICE and BBUGSS standards.We aimed to establish baseline data to encourage emergency laparoscopic cholecystectomies in our hospital and reduce repeated hospital visits for patients with acute gallbladder disease. Results Forty-eight patients had emergency laparoscopic cholecystectomy in the period reviewed, mean age was 44.3 years and females accounted for approximately 71% (n=34) of the group. 66.7% (n=32) of patients had their surgery within seven days of diagnosiswith acute gallstone disease; 50% (n=24)of patients had no adverse intraoperative event.No patient had biliary tract injury despite a high number of difficult cases. Overall there was no correlation between duration before surgery and intraoperative difficulty or readmission rates.

Laparoscopic Cholecystectomy in Pregnancy: A Seven-Year Retrospective Study From an Australian Tertiary Center.

Background Cholecystectomy is the second most common non-obstetric indication for surgery during pregnancy; however, there is little recent literature specifically exploring perioperative care approaches, and a paucity of Australian data exists. This study investigates the incidence of laparoscopic cholecystectomy (LC) during pregnancy, peri-operative management, and post-operative outcomes in a single Australian tertiary center. Methods A retrospective analysis of LCs performed on pregnant patients between the ages of 16 and 50 years at a tertiary hospital between 2016 and 2023 was completed. Results Twenty-three patients underwent LC. The median gestational age was 17+4weeks (4+3-30+6). Cases were performed in all three trimesters, with the majority in the second trimester (n=12, 52.2%). Surgery indications were recurrent biliary colic (n=11, 47.8%), acute cholecystitis (n=8, 34.8%), and gallstone pancreatitis (n=4, 17.4%). Obstetrics and Gynecology (O&G) consultations occurred in 56.5% (n=13) of cases. Fetal heart rate (FHR) was recorded perioperatively in 82.6% (n=19) of cases. Preoperative steroids were given to 40% of eligible patients. An intraoperative cholangiogram was performed in 12 (52.2%) cases, of which eight (66.7%) utilized abdominal shielding. There was no perioperative maternal mortality nor fetal loss. Surgical morbidities were pancreatitis (n=1), bile leak (n=1), and intraoperatively recognized bile duct injury (n=1). Two threatened preterm labors and five (26.3%) preterm deliveries occurred. Conclusion Performing LC in pregnancy does carry a risk of major morbidity; however, there was no mortality or fetal loss across all trimesters. The decision to perform abdominal shielding during an intraoperative cholangiogram should be approached sensitively in a case-by-case manner, given recent paradigm shifts in radiology. A multidisciplinary approach with standardized local perioperative care policies regarding procedures such as O&G consultation, perioperative steroid use, and FHR monitoring is strongly recommended.

Regulation of CD47 expression on CD14+ monocytes by interferon-α in PBC patients.

Primary biliary cholangitis (PBC) is a chronic intrahepatic cholestatic autoimmune liver disease characterized by inflammatory injury of small and medium-sized bile ducts in the liver. The pathogenesis of PBC has yet to be entirely understood. CD47/signal-regulatory protein alpha (SIRPα) is closely related to developing autoimmune diseases by promoting inflammatory response. However, the effect of CD47/SIRPα on inflammatory response in PBC patients is still unclear. We investigated the expression of CD47/SIRPα and the effect of inflammatory cytokines on the CD47 expression, analyzed potential autoantibodies against CD47 and the effect of anti-CD47 antibody on the inflammatory response in PBC, provided laboratory basis for the study of the pathogenesis and targets for non-invasive diagnosis and treatment on PBC. The expression levels of CD47 and SIRPα on peripheral blood mononuclear cells (PBMC) were measured in 14 patients with PBC (the PBC group) and 13 healthy subjects (the Control group) by flow cytometry (FCM). The PBMC derived from healthy subjects were stimulated with healthy subjects' serum, PBC patients' serum, IFN-α or TNF-α, and the CD47 expression level on CD14+ monocytes was detected by FCM. The level of serum anti-CD47 antibody or IFN-α in PBC patients and healthy subjects was analyzed by ELISA. FCM was used to examine the TNF-α expression level in CD14+ monocytes of healthy subjects stimulated with isotype control antibody, anti-CD47 antibody, LPS or LPS combined with CD47 antibody. The CD47 expression level on the CD14+ monocytes in PBC patients was statistically higher than that in the Control group (P<0.01). Compared with the Control group (PBMC+healthy serum), the CD47 expression on CD14+ monocyte stimulated with the PBC patients' serum (PBMC+PBC patients' serum) was increased (P<0.001); the CD47 expression on CD14+ monocyte stimulated with IFN-α (PBMC + IFN-α) increased gradually with the increased concentration of IFN-α (P<0.05). However, there was no similar trend on CD14+ monocyte stimulated with the TNF-α (PBMC+TNF-α) (P>0.05). The levels of serum anti-CD47 antibody and IFN-α in the PBC patients were higher than those in healthy subjects (P<0.05). The TNF-α expression level in CD14+ monocyte stimulated with the LPS (PBMC+LPS) or anti-CD47 antibody+LPS group (PBMC+LPS+anti-CD47 antibody) was significantly increased than that in the Control group (PBMC+isotype control antibody) (P<0.01 and P<0.001, respectively). The TNF-α expression level in CD14+ monocyte stimulated with the anti-CD47 antibody + LPS was higher than that with the LPS (P< 0.05). The CD47 may be related to the pathogenesis of PBC by inflammatory response. The CD47/SIRPα signal were imbalanced in PBC patients. The presence of serum anti-CD47 antibodies in PBC patients provides a laboratory basis for clinical diagnosis and treatment.

Desarrollo de una Unidad de Cirugía Hepatobiliar Compleja y Trasplante Hepático en un hospital público: a una década de su formación

Background: Centralizing hepatobiliary disease in specialized centers can reduce morbidity and mortality rates and improve long-term outcomes. Objective: The aim of the present study was to describe the clinical and pathological features and surgical outcomes of a series of patients operated on in the Hepatobiliary Surgery and Liver Transplantation Unit of Hospital El Cruce during its first 10 years, as well as the scientific and educational activity of its members. Material and methods: We conducted a descriptive and retrospective study. The information was retrieved from a prospective database. The procedures were classified according to their complexity. An analysis was conducted on liver transplantations (LTs), liver resections and complex biliary procedures, performed from 2013 to 2022. Results: Of 1449 surgical procedures, 832 were high-complexity interventions (58%). A total of 452 LTs were performed, 14 (3%) were combined liver and kidney transplantations; overall transplant survival was 83%, 77% and 75% at 1, 3 and 5 years, respectively. Primary graft dysfunction was observed in 5 cases (1.1%). There were 254 liver resections; 58 cases (23%) were related to benign liver diseases, 155 (61%) to malignancies, and 41 (16%) were associated with living donor transplants. Overall morbidity was 27% and in-hospital mortality was 2%. A total of 106 bilio-digestive bypass procedures were carried out, 53 in patients with bile duct injury. Thirty-day morbidity was 42%, and most cases were minor complications (28%). Other procedures included 17 cephalic pancreaticoduodenectomies and 3 splenectomies and distal pancreatectomies. We have published numerous papers, delivered presentations and courses, and implemented a fellowship program in the specialty since 2015. Conclusion: Centralizing hepatobiliary diseases at a high-complexity center led to comparable outcomes with those reported in international series.

Resección hepática como tratamiento de lesión de vía biliar compleja

Bile duct injury represents a serious health problem, with its incidence doubling since the advent of laparoscopic cholecystectomy. In cases of complex lesions affecting the hepatic confluence, association with vascular injuries, hepatic atrophy, cholangitis or failed repair, treatment is often challenging. We report the case of a female patient with a complex bile duct injury due to vascular involvement of the right hepatic pedicle who developed right liver atrophy. In the presence of septic complications, hepatectomy was necessary, along with a definitive repair of the biliary tract, resulting in positive outcomes.

Beta Thalassemia Presenting with Neonatal Cholestasis and Extensive Hemosiderosis: A Case Report

Neonatal cholestasis is caused by various forms of liver injury and has a complex etiological background. Among these, cases of severe cholestasis due to primary hemolytic disease are rare. Herein, we report a case in which thalassemia-induced severe hemolysis caused bile duct injury by hemosiderosis, with cholestasis occurring shortly after birth and lasting for &gt;4 months. In addition, complete recovery of liver pathology was observed both biochemically and histologically. Hence, clinicians should consider hemolytic disease as a rare cause of neonatal cholestasis in the differential diagnosis of neonates as well as the advisability of conservative treatment based on case progression.

A retrospective study of laparoscopic, robotic-assisted, and open emergent/urgent cholecystectomy based on the PINC AI Healthcare Database 2017–2020

BackgroundRobotic-assisted cholecystectomy (RAC) is becoming increasingly common, but the outcomes of emergent/urgent robotic-assisted cholecystectomies compared to emergent laparoscopic (LC) and open cholecystectomies (OC) remain understudied.MethodsThe PINC AI Healthcare Database was queried to identify adults who underwent emergent or urgent (Em-Ur) cholecystectomy between January 1, 2017, and December 31, 2020. Immediate postoperative and 30-day outcomes were identified including intraoperative complications, transfusion, conversion, postoperative complication, and hospital length of stay. Propensity score matching was done to compare outcomes between Em-Ur robotic-assisted, laparoscopic, and open cholecystectomies Subgroup analyses were performed comparing RAC done with and without fluorescent imaging as well as comparing RAC and LC performed for patients with class 3 obesity (BMI ≥ 40 kg/m2).ResultsRAC Em-Ur cholecystectomies are being performed with increasing frequency and is the most utilized modality for patients with class 3 obesity. There was no difference in intraoperative complications (0.3%), bile duct injury (0.2%), or postoperative outcomes between RAC and LC. LC had significantly shorter operating room times (96 min (75,128)) compared to RAC (120 min (90,150)). There was a significant lower rate of conversion to open in RAC (1.9%) relative to LC (3.2%) in both the overall population and the class 3 obesity sub-analysis (RAC-2.6% vs. LC-4.4%). There was no difference in outcomes in robotic-assisted cholecystectomies done with and without fluorescent imaging.ConclusionsA comparison of propensity score-matched cohorts of emergent/urgent robotic-assisted and laparoscopic cholecystectomy indicates that robotic-assisted cholecystectomy is a safe alternative to laparoscopic cholecystectomy, and that both have superior outcomes to open cholecystectomies.

Selpercatinib-induced hepatotoxicity: A rare case report

Abstract Introduction/Objective Selpercatinib (Retevmo) is a highly selective rearranged during transfection (RET) kinase inhibitor indicated for treatment of solid tumors with RET gene mutation or fusion, such as medullary thyroid carcinoma or non-small cell lung carcinoma. Among selpercatinib’s side effects, severe hepatotoxicity was only seen in 3% of the patients. Here we report a case of selpercatinib-induced hepatotoxicity, which has not been well characterized before. Methods/Case Report The patient was a 56-year-old female who had medullary thyroid carcinoma with RET M918T mutation (pT3aN1b) status post total thyroidectomy. Recurrence occurred and selpercatinib treatment was initiated. Then the patient complained of mouth sores, tongue sensitivity, and lower extremity cramping. The dosage was reduced to half. The magnetic resonance imaging on day 67 of selpercatinib treatment showed heterogeneous enhancement in the right hepatic lobe, compatible with parenchymal liver disease/hepatitis, trace perihepatic ascites, and mild splenomegaly. On day 71, liver function abnormalities were detected (ALK 315 IU/L, ALT 745 IU/L, AST 899 IU/L, total bilirubin 7.7 mg/dL). Workups including autoimmune hepatitis serology, viral hepatitis, or other infections were all negative. She had no history of other drug use. On day 72, a liver biopsy was performed that demonstrated mild to moderate portal lymphocyte-predominant mixed inflammation with interface activity. The lobules showed marked inflammation with hepatocyte disorganization, acidophil bodies, hepatocyte dropout, and rare lipogranulomas. Bile duct injury and patchy canalicular cholestasis were also noted. Trichrome stain showed focal bridging fibrosis. Overall, the histologic findings were acute and chronic hepatitis pattern injury, favor selpercatinib-induced hepatotoxicity. Selpercatinib was discontinued. All liver enzymes gradually returned to normal levels on day 169. Results (if a Case Study enter NA) NA Conclusion Our study suggests that screening patients for abnormal liver function tests prior to and monitoring periodically during selpercatinib treatment is necessary. Based on the severity of hepatotoxicity, withholding, reducing the dose, or permanently discontinuing selpercatinib is recommended.

An interesting case report of delayed presentation of post-cholecystectomy benign biliary stricture

Background The most common cause of benign biliary stricture is bile duct injury after cholecystectomy. Benign biliary strictures are associated with a broad spectrum of signs and symptoms, ranging from subclinical disease with mild elevation of liver enzymes to complete obstruction with jaundice, pruritis, and cholangitis ultimately leading to biliary cirrhosis. The average duration for stricture development after cholecystectomy is around 7 months. This is a case report of a benign biliary stricture presenting 14 years after laparoscopic conversion to open cholecystectomy without the development of recurrent cholangitis and secondary biliary cirrhosis.

Comparing Bile Duct Injuries: Open Versus Laparoscopic Cholecystectomy

Bile duct injuries in the context of cholecystectomy present a multifaceted challenge for healthcare professionals. This review article delves into the epidemiology, theoretical framework, and comparative analysis of bile duct injuries, emphasizing open versus laparoscopic cholecystectomy. With a slightly higher risk associated with laparoscopy, understanding the risk factors, early detection, and management strategies is crucial. Long-term surveillance, comprehensive follow-up care, and individualized surgical approaches play a pivotal role in perfecting patient outcomes. The ability of the surgical team and prudent patient selection significantly influence the risk of injuries. This review underscores the complexity of bile duct injuries, advocating for ongoing research and advancements to minimize their incidence and improve patient care.

HPB P58 Laparoscopic cholecystectomy as a training case in the post-Covid world

Abstract Background Laparoscopic cholecystectomy is an index procedure for all higher surgical trainees, regardless of sub-specialty. Minimum numbers and evidenced ‘Level 4’ competency are necessary for successful completion of training. The Covid-19 pandemic led to falls in training opportunities, during the acute phase itself and in the current drive to reduce elective waiting lists. More cases are outsourced and those cases that are being performed in the NHS may be more complex due to longer waiting times. These twin pressures have led to concerns that training opportunities for laparoscopic cholecystectomy are being limited. This study evaluated the training opportunities for laparoscopic cholecystectomy. Methods All patients who had laparoscopic cholecystectomy over a four-month period, from January 2023 to April 2023 were identified from a prospectively maintained database of operations. Electronic patient records were interrogated to gather pre-operative data (symptomology, co-morbidities, acuity of presentation, pre-operative investigations), intra-operative findings and progress (grade of primary surgeon, nature of operation) and post-operative outcomes and complications. Factors which were associated with the case being performed by a trainee were assessed, as well as differences in outcomes between consultant and registrar procedures. Results There were 150 laparoscopic cholecystectomies performed during the study period. 79 (53%) of these cases were performed acutely ('hot' gallbladders). Registrars performed 36 elective laparoscopic cholecystectomies (51%) and 42 acute cases (53%). Operating time was comparable between registrars and consultants (median operating time [registrar vs. consultant], 72 vs. 78 minutes). There were no particular pre-operative factors that predicted a case being performed by a trainee. There were no differences in post-operative outcome or complication between grade of primary surgeon; there were no bile duct injuries. There were three patients who had a return-to-theatre (2 registrar, 1 consultant case). Conclusions The current case mix in our hospital has meant that just over half the laparoscopic cholecystectomies performed were completed by a trainee. Not a single case was performed by an 'SHO' level surgeon, suggesting that this operation is now the preserve of higher surgical trainees. Without a high-functioning acute gallbladder service, training opportunities for this operation would be severely limited. It is safe to train laparoscopic cholecystectomy, even in the acute setting, and more should be done to identify factors which could improve training opportunities.

HPB P55 An audit of the quality standards for Laparoscopic Cholecystectomy. Compliance with the AUGIS standards (AUGIS: Association of Upper Gastrointestinal Surgery of Great Britain and Ireland)

Abstract Background Laparoscopic cholecystectomy, which is a minimally invasive operation, is one of the most common surgical procedures in the UK and worldwide. Indications for LC include acute or chronic cholecystitis, symptomatic cholelithiasis, biliary dyskinesia, acalculous cholecystitis, gallstone pancreatitis, and gallbladder masses or polyps. The purpose of this audit was to assess and compare the outcomes after LC with the standards published by the association of upper GI surgeons (AUGIS) and to formulate measures to improve services at Royal Albert Edward Infirmary. Methods A data of 56 patients who underwent cholecystectomy was analysed retrospectively by two different auditors. All patients who underwent both open and laparoscopic cholecystectomies were included in this study. Results Our results showed that the majority of the patients (40/56) were females. Only 3 patients had open cholecystectomy while the rest of the 53 patients had LC. 67% (38/56) were done as a day case and discharged home the same day after surgery. None of the patients had an emergency and thus timely management of the disease in terms of surgery within the first 7 days of presentation. 7/56 patients were readmitted with different complications. No bile duct injuries were recorded. Conclusions Our hospital was found out to be compliant with only ⅙ criteria assessed. This study concludes that there is a need to improve outcomes in all domains especially the easily reversible factors such as day case rates and readmission due to complications.

OGBN P10 Fenestrating versus reconstituting subtotal cholecystectomy for difficult gallbladder: A systematic review and meta-analysis

Abstract Background To evaluate comparative outcomes of fenestrating and reconstituting subtotal cholecystectomy (STC) in patients with difficult gallbladder. Methods A systematic search of electronic data sources and bibliographic reference lists were conducted. All comparative studies reporting outcomes of laparoscopic fenestrating and reconstituting STC were included and their risk of bias were assessed using ROBINS-I tool. Results Seven comparative studies were included enrolling 590 patients undergoing laparoscopic STC using either fenestrating (n=353) or reconstituting (n=237) approaches. Although fenestrating STC was associated with a significantly higher rate of bile leak (OR:2.47, p=0.007) compared to reconstituting STC, both approaches were comparable in terms of resolution of bile leak without (RD:-0.02, p=0.86) or with (OR:1.84, p=0.40) postoperative ERCP. Moreover, there was no significant difference in development of bile duct injury (RD:-0.02, p=0.16), need for postoperative ERCP (OR:1.36, p=0.49), wound infection (RD:0.03, p=0.27), re-operation (OR:0.95, p=0.95), gallbladder remnant cholecystitis (OR:0.21, p=0.09) or need for completion cholecystectomy (RD:0.01, p=0.59) between two groups. Conclusions Although fenestrating STC increases risk of bile leak compared with the reconstituting approach, this can be managed successfully with postoperative ERCP if not resolved spontaneously. We encourage low threshold for fenestrating approach in difficult situations, considering its relatively benign postoperative course and long-term outcomes.

Real-time fluorescence imaging with indocyanine green during laparoscopic duodenum-preserving pancreatic head resection

BackgroundLaparoscopic duodenum-preserving pancreatic head resection (LDPPHR) is a surgical method used to treat benign and low-grade malignant pancreatic head tumors. This study aimed to determine the protective effect of common bile duct in LDPPHR using indocyanine green (ICG) fluorescence imaging. MethodsA retrospective analysis of 30 patients treated with LDPPHR at the Second Affiliated Hospital of Nanchang University between January 2015 and November 2022 was performed. Patients were divided into two groups based on ICG use: ICG and non-ICG. ResultsThirty patients received LDPPHR, 11 males and 19 females, and the age was 50.50 (M (IQR)) years (range: 19–76 years). LDPPHR was successfully performed in 27 (90 %) patients, LPD was performed in 1 (3 %) patient, and laparotomy conversion was performed in 2 (7 %) patients. One patient (3 %) died 21 days after surgery. The incidence of intraoperative bile duct injury in the ICG group was lower than that in the non-ICG group (10 % vs 60 %, P = 0.009), and the operation time in the ICG group was shorter than that in the non-ICG group (311.9 ± 14.97 vs 338.05 ± 18.75 min, P < 0.05). Postoperative pancreatic fistula occurred in 16 patients (53 %), including 10 with biochemical leakage (62.5 %), four with grade B (25 %), and two with grade C (12.5 %). Postoperative bile leakage occurred in four patients (13 %). ConclusionsThe ICG fluorescence imaging technology in LDPPHR helps protect the integrity of the common bile duct and reduce the occurrence of intraoperative bile duct injury, postoperative bile leakage, and bile duct stenosis.
