Project description:BackgroundBile duct injuries (BDI) can occur after a cholecystectomy procedure performed by any surgeons. These ensured a poor experience for patients and surgeons and marred the minimally invasive surgery approach, which should have promised rapid recovery. This study aimed to evaluate the management of BDI following cholecystectomy procedure in Cipto Mangunkusumo Hospital, Jakarta, as a tertiary hospital.MethodDescriptive retrospective cross-sectional design was used on open and laparoscopic cholecystectomy performed between January 2008 and December 2018. This study is reported in line with STROCSS 2019 Criteria.ResultA total of 24 patients with BDI were included, with female preponderance (62,5%) with a median age 45 (21-58) years. Sixteen post-laparoscopy cases were classified according to Strasberg classification; 6 cases were type E3, 2 cases each of type E1 and E2, and one case each of Strasberg C and D. The remaining 4 were Strasberg A. Eight post-open cases were classified based on Bismuth criteria: 4 cases of Bismuth I, 1 case of Bismuth II, and 3 cases of Bismuth III. Five cases were presented with massive biloma, 7 with jaundice, and 10 cases with biliary-pancreatic fluid production through the surgical drain. The average time of problem recognition to patient's admission was 19 (7-152) days and admission to surgery was 14 days. Roux-en-Y hepaticojejunostomy was performed in 18 cases, choledocho-duodenostomy in 2 cases, and primary ligation cystic duct in 4 cases. Post-operative follow-up showed 2 patients had recurrent cholangitis, 2 superficial surgical site infection, and 2 relaparotomy due to bile anastomosis leakage and burst abdomen. The median length of hospital stay was 38 (14-53) days with zero hospital mortality. No stricture detected in long term follow-up.ConclusionCommon bile duct was the most frequent site of BDI, and Roux-en-Y hepaticojejunostomy reconstruction performed by HPB surgeons on high volume center results in a good outcome.

Project description:Introduction Embryonal Rhabdomyosarcoma (ERMS) is a malignant soft tissue musculoskeletal tumor which constitutes about 0.06% of all malignancies affecting children. Biliary tract ERMS is still rare, though it is considered the most common cause of malignant obstructive jaundice in children. Case presentation A report of a 2-year-old boy, who was presented with recurrent episodes of scleral icterus of three months duration, is added to the related literature. His labs went with obstructive jaundice and the radiological investigations were consistent with a diagnosis of choledochal cyst. The found mass was suspected to be an ERMS of common bile duct and turned out to be so by the histopathology. He was managed totally by laparoscope, both excision and hepaticojejunostomy reconstruction, which is an extremely uncommon entity. Conclusion Common Bile Duct Rhabdomyosarcoma is rare and diagnosis at this anatomical site is difficult. Our case highlights the feasibility of laparoscopic resection and hepaticojejunostomy reconstruction with very good results at 16-month follow up and parents' gratitude as well. Highlights • Rhabdomyosarcoma (RMS) is a rare malignant tumor affecting children.• RMS is worth considering when dealing with a choledochal cyst.• Surgical approaches reported for biliary RMS were laparotomies.• Laparoscopic management is feasible for biliary RMS.• Our case is the least invasive surgical approach reported up to date.

Project description:Background and study aimsBile stones represent a highly prevalent condition and abnormalities of the biliary tree predispose to stone recurrence due to development of biliary stasis. In our study, we assessed the importance of an altered bile duct course for stone formation.Patients and methods1,307 patients with choledocholithiasis in the absence of any associated hepatobiliary disease who underwent endoscopic retrograde cholangiopancreatography (ERCP) between 2002 and 2009 were analysed. The angle enclosed between the horizontal portion of the common bile duct (CBD) and the horizontal plane was measured (angle ?). Oblique common bile duct (OCBD) was defined as a CBD with angle ? < 45°.Results103 patients (7.9%) were found to harbour OCBD and these were compared to 104 randomly selected control subjects. Compared to controls, OCBD patients were (i) significantly older (72 ± 13 vs. 67 ± 13, p<0.00001); (ii) more frequently underwent a cholecystectomy (p = 0.02) and biliary surgery (p = 0.003) prior to the diagnosis and (iii) more often developed chronic pancreatitis (p = 0.04) as well as biliary fistulae (p = 0.03). Prior to and after ERCP, OCBD subjects displayed significantly elevated cholestatic parameters and angle ? negatively correlated with common bile duct diameter (r = -0.29, p = 0.003). OCBD subjects more often required multiple back-to-back ERCP sessions to remove bile stones (p = 0.005) as well as more ERCPs later on due to recurrent stone formation (p<0.05).ConclusionOCBD defines a novel variant of the biliary tree, which is associated with chronic cholestasis, hampers an efficient stone removal and predisposes to recurrence of bile duct stones.

Project description:The reconstruction of high-level bile duct injury is challenging because exposure of the hilar area is limited and sometimes inaccessible by the Hepp-Couinaud approach. We describe a maneuver for total hilar exposure to perform complex bile duct injury reconstruction. After adhesions surrounding the liver are divided, intraoperative ultrasonography is used to delineate the hilar and intrahepatic biliary anatomy. Surgical exposure of the biliary system is achieved by our maneuver, which consists of four steps: (1) identification of landmark structures, such as the base of the umbilical fissure, the inferior edge of segment 4b, the cystic-hilar plate junction, and the right anterior portal pedicle; (2) lowering of the hilar plate; (3) hepatotomy along the right anterior pedicle; and (4) connection of the hepatotomy to the base of segment 4b. This maneuver allows the liver to be flipped upward, which facilitates clear exposure of the hilar duct and preserves the liver parenchyma. The anterior parts of the right and left hepatic duct are then opened, a wide-hepaticojejunostomy anastomosis is achieved for biliary reconstruction, and a jejunal subcutaneous limb is created. We used this maneuver for treating complex bile duct injury in six cases; none of the patients has died, and two had Clavien-Dindo grade III complications, including surgical site infection and intra-abdominal collection. The total hilar exposure maneuver is thus feasible and safe. It provides excellent exposure of both hepatic ducts and is a good surgical alternative to the Hepp-Couinaud approach in cases of high-level injury.

Project description:The biliary tree is an essential component of transplantable human liver tissue. Despite recent advances in liver tissue engineering, attempts at re-creating the intrahepatic biliary tree have not progressed significantly. The finer branches of the biliary tree are structurally and functionally complex and heterogeneous and require harnessing innate developmental processes for their regrowth. Here we demonstrate the ability of decellularized liver extracellular matrix (dECM) hydrogels to induce the in vitro formation of complex biliary networks using encapsulated immortalized mouse small biliary epithelial cells (cholangiocytes). This phenomenon is not observed using immortalized mouse large cholangiocytes, or with purified collagen 1 gels or Matrigel. We also show phenotypic stability via immunostaining for specific cholangiocyte markers. Moreover, tight junction formation and maturation was observed to occur between cholangiocytes, exhibiting polarization and transporter activity. To better define the mechanism of duct formation, we utilized three fluorescently labeled, but otherwise identical populations of cholangiocytes. The cells, in a proximity dependent manner, either branch out clonally, radiating from a single nucleation point, or assemble into multi-colored structures arising from separate populations. These findings present liver dECM as a promising biomaterial for intrahepatic bile duct tissue engineering and as a tool to study duct remodeling in vitro.

Project description:BackgroundCommon bile duct (CBD) stones can be managed by either endoscopic retrograde cholangiopancreatography (ERCP) or laparoscopic common bile duct exploration (LCBDE). The aim of this survey was to document the management of CBD stones by European-African HPB Association (E-AHPBA) members.MethodsAll 331 members of the E-AHPBA were invited by personal email to participate to an online survey.ResultsNinety-three (28%) surgeons replied within 2 months. Responding surgeons were attending surgeons (84%), working as HPB surgeons (75%) in academic hospitals (73%). In patients with clinically suspected CBD stones, MRCP was the preferred diagnostic test for 61% of respondents. LCBDE was the preferred therapeutic strategy for 11 (12%) respondents only. Previous gastric surgery was an absolute contraindication to ERCP for 47% of respondents. Absence of CBD dilation was considered an absolute contraindication for LCBDE in 24% of respondents. Yearly caseload exceeded 10 patients for only 30% of 56 centers performing LCBDE. The transcystic approach was preferred by 39% of surgeons performing LCBDE. There was considerable variation amongst respondents with regard to type and duration of drainage, bile duct closure technique and follow-up after LCBDE.ConclusionIndications for single-stage LCBDE are not standardized and do not appear well established across E-AHPBA members.

Project description:ObjectivesLaparoscopic cholecystectomy - associated bile duct injury is a clinical problem with bad outcome. The study aimed to analyze the outcome of surgical management of these injuries.Patients and methodsWe retrospectively analyzed 69 patients underwent surgical management of laparoscopic cholecystectomy related major bile duct injuries in the period from the beginning of 2013 to the beginning of 2018.ResultsRegarding injury type; the Leaking, Obstructing, leaking + obstructing, leaking + vascular, and obstructing + vascular injuries were 43.5%, 27.5%, 18.8%, 2.9%, and 7.2% respectively. However, the Strasberg classification of injury was as follow E1 = 25, E2 = 32, E3 = 8, and E4 = 4. The definitive procedures were as follow: end to end biliary anastomosis with stenting, hepaticojejunostomy (HJ) with or without stenting, and RT hepatectomy plus biliary reconstruction with stenting in 4.3%, 87%, and 8.7% of patients respectively. According to the time of definitive procedure from injury; the immediate (before 72 h), intermediate (between 72 h and 1.5months), and late (after1.5 months) management were 13%, 14.5%, and 72.5% respectively. The hospital and/or 1month (early) morbidity after definitive treatment was 21.7%, while, the late biliary morbidity was 17.4% and the overall mortality was 2.9%, on the other hand, the late biliary morbidity-free survival was 79.7%. On univariate analysis, the following factors were significant predictors of early morbidity; Sepsis at referral, higher Strasberg grade, associated vascular injury, right hepatectomy with biliary reconstruction as a definitive procedure, intra-operative bleeding with blood transfusion, liver cirrhosis, and longer operative times and hospital stays. However, the following factors were significantly associated with late biliary morbidity: Sepsis at referral, end to end anastomosis with stenting, reconstruction without stenting, liver cirrhosis, operative bleeding, and early morbidity.ConclusionSepsis at referral, liver cirrhosis, and operative bleeding were significantly associated with both early and late morbidities after definitive management of laparoscopic cholecystectomy related major bile duct injuries, so it is crucial to avoid these catastrophes when doing those major procedures.

Project description:BackgroundLiver metabolites are used to diagnose disease and examine drugs in clinical pharmacokinetics. Therefore, development of an in vitro assay system that reproduces liver metabolite recovery would provide important benefits to pharmaceutical research. However, liver models have proven challenging to develop because of the lack of an appropriate bile duct structure for the accumulation and transport of metabolites from the liver parenchyma. Currently available bile duct models, such as the bile duct cyst-embedded extracellular matrix (ECM), lack any morphological resemblance to the tubular morphology of the living bile duct. Moreover, these systems cannot overcome metabolite recovery issues because they are established in isolated culture systems. Here, we successfully established a non-continuous tubular bile duct structure model in an open-culture system, which closely resembled an in vivo structure. This system was utilized to effectively collect liver metabolites separately from liver parenchymal cells.ResultsTriple-cell co-culture of primary rat hepatoblasts, rat biliary epithelial cells, and mouse embryonic fibroblasts was grown to mimic the morphogenesis of the bile duct during liver development. Overlaying the cells with ECM containing a Matrigel and collagen type I gel mixture promoted the development of a tubular bile duct structure. In this culture system, the expression of specific markers and signaling molecules related to biliary epithelial cell differentiation was highly upregulated during the ductal formation process. This bile duct structure also enabled the separate accumulation of metabolite analogs from liver parenchymal cells.ConclusionsA morphogenesis-based culture system effectively establishes an advanced bile duct structure and improves the plasticity of liver models feasible for autologous in vitro metabolite-bile collection, which may enhance the performance of high-throughput liver models in cell-based assays.

Project description:Bile duct injury (BDI) is a dangerous complication of cholecystectomy, with significant postoperative sequelae for the patient in terms of morbidity, mortality, and long-term quality of life. BDIs have an estimated incidence of 0.4-1.5%, but considering the number of cholecystectomies performed worldwide, mostly by laparoscopy, surgeons must be prepared to manage this surgical challenge. Most BDIs are recognized either during the procedure or in the immediate postoperative period. However, some BDIs may be discovered later during the postoperative period, and this may translate to delayed or inappropriate treatments. Providing a specific diagnosis and a precise description of the BDI will expedite the decision-making process and increase the chance of treatment success. Subsequently, the choice and timing of the appropriate reconstructive strategy have a critical role in long-term prognosis. Currently, a wide spectrum of multidisciplinary interventions with different degrees of invasiveness is indicated for BDI management. These World Society of Emergency Surgery (WSES) guidelines have been produced following an exhaustive review of the current literature and an international expert panel discussion with the aim of providing evidence-based recommendations to facilitate and standardize the detection and management of BDIs during cholecystectomy. In particular, the 2020 WSES guidelines cover the following key aspects: (1) strategies to minimize the risk of BDI during cholecystectomy; (2) BDI rates in general surgery units and review of surgical practice; (3) how to classify, stage, and report BDI once detected; (4) how to manage an intraoperatively detected BDI; (5) indications for antibiotic treatment; (6) indications for clinical, biochemical, and imaging investigations for suspected BDI; and (7) how to manage a postoperatively detected BDI.

Project description:BACKGROUND: It is controversial whether selective endoscopic sphincterotomy or routine laparoscopic bile duct exploration is the optimal treatment for choledocholithiasis. Magnetic resonance cholangio-pancreatography (MRCP) is a safe and accurate imaging modality; this study evaluated its use in a clinical algorithm for the management of suspected choledocholithiasis. PATIENTS AND METHODS: Consecutive patients presenting with suspected common bile duct (CBD) stones were managed according to an algorithm involving the selective use of MRCP to identify patients who required endoscopic sphincterotomy and bile duct clearance. Following radiological demonstration of a clear CBD, all patients were considered for cholecystectomy. RESULTS: From 157 consecutive patients, 68 proceeded straight to endoscopic sphincterotomy, which was therapeutic in 59. Of 89 who underwent MRCP, choledocholithiasis was demonstrated in 29; subsequent endoscopic sphincterotomy was therapeutic in 22. MRCP demonstrated a clear CBD in the remaining 60 patients. Seventy-four patients subsequently underwent cholecystectomy, with a conversion rate of 9% and a median postoperative stay of 1 day. There were no instances of post-sphincterotomy pancreatitis or haemorrhage requiring transfusion. CONCLUSION: An algorithm involving selective MRCP with endoscopic sphincterotomy is a safe, effective means of managing suspected choledocholithiasis, particularly where the expertise, equipment or theatre time for laparoscopic bile duct exploration is not routinely available.
