Abstract
In this editorial we comment on the article by Emara et al published in the recent issue of the World Journal of Gastrointestinal Surgery. Previously, surgery was the primary treatment for bile duct injuries (BDI). The treatment of BDI has advanced due to technological breakthroughs and minimally invasive procedures. Endoscopic and percutaneous treatments have largely supplanted surgery as the primary treatment for most instances in recent years. Patient management, including the specific technique, is typically impacted by local knowledge and the kind and severity of the injury. Endoscopic therapy is a highly successful treatment for postoperative benign bile duct stenosis and offers superior long-term outcomes compared to surgical correction. Based on the damage features of BDI, therapeutic options include endoscopic duodenal papillary sphincterotomy, endoscopic nasobiliary drainage, and endoscopic biliary stent implantation.

World J Gastrointest Surg 2023; 15:2709-2718. [PMID: 38222007 PMCID: PMC10784825 DOI: 10.4240/wjgs.v15.i12.2709] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/20/2023] [Revised: 10/26/2023] [Accepted: 11/24/2023] [Indexed: 12/27/2023] Open
Abstract
Post-cholecystectomy iatrogenic bile duct injuries (IBDIs), are not uncommon and although the frequency of IBDIs vary across the literature, the rates following the procedure of laparoscopic cholecystectomy are much higher than open cholecystectomy. These injuries caries a great burden on the patients, physicians and the health care systems and sometime are life-threatening. IBDIs are associated with different manifestations that are not limited to abdominal pain, bile leaks from the surgical drains, peritonitis with fever and sometimes jaundice. Such injuries if not witnessed during the surgery, can be diagnosed by combining clinical manifestations, biochemical tests and imaging techniques. Among such techniques abdominal US is usually the first choice while Magnetic Resonance Cholangio-Pancreatography seems the most appropriate. Surgical approach was the ideal approach for such cases, however the introduction of Endoscopic Retrograde Cholangio-Pancreatography (ERCP) was a paradigm shift in the management of such injuries due to accepted success rates, lower cost and lower rates of associated morbidity and mortality. However, the literature lacks consensus for the optimal timing of ERCP intervention in the management of IBDIs. ERCP management of IBDIs can be tailored according to the nature of the underlying injury. For the subgroup of patients with complete bile duct ligation and lost ductal continuity, transfer to surgery is indicated without delay. Those patients will not benefit from endoscopy and hence should not do unnecessary ERCP. For low-flow leaks e.g. gallbladder bed leaks, conservative management for 1-2 wk prior to ERCP is advised, in contrary to high-flow leaks e.g. cystic duct leaks and stricture lesions in whom early ERCP is encouraged. Sphincterotomy plus stenting is the ideal management line for cases of IBDIs. Interventional radiologic techniques are promising options especially for cases of failed endoscopic repair and also for cases with altered anatomy. Future studies will solve many unsolved issues in the management of IBDIs.

[PMID: 37886633 PMCID: PMC10598674 DOI: 10.3389/fsurg.2023.1280383] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2023] [Accepted: 09/27/2023] [Indexed: 10/28/2023] Open
Abstract
Objectives To evaluate the clinical presentation, management, and outcomes of bile duct injuries (BDIs) after laparoscopic cholecystectomy (LC). Methods This is a case series of 28 patients with BDIs after LC treated at a tertiary hospital in Vietnam during the 2006-2021 period. The BDI's clinical presentations, Strasberg classification types, management methods, and outcomes were reported. Results BDIs were diagnosed intraoperatively in 3 (10.7%) patients and postoperatively in 25 (89.3%). The BDI types included Strasberg A (13, 46.4%), D (1, 3.6%), E1 (1, 3.6%), E2 (4, 14.3%), E3 (5, 17.9%), D + E2 (2, 7.1%), and nonclassified (2, 7.1%). Of the postoperative BDIs, the injury manifested as biliary obstruction (18, 72.0%), bile leak (5, 20.0%), and mixed scenarios (2, 8.0%). Regarding diagnostic methods, endoscopic retrograde cholangiopancreatography (ERCP) was more useful in bile leak scenarios, while multislice computed tomography, magnetic resonance cholangiopancreatography, and percutaneous transhepatic cholangiography were more useful in biliary obstruction scenarios. All 28 BDIs were successfully treated. ERCP with stenting was very effective in the majority of Strasberg A BDIs. For more complex BDI types, hepaticocutaneous jejunostomy was a safe and effective approach. The in-hospital morbidities included postoperative pneumonia (2, 10.7%) and biliary-enteric anastomosis leakage (1, 5.4%). There was no cholangitis or anastomotic stenosis during the follow-up after discharge (median 18 months). Conclusions The majority of BDIs are type A and diagnosed postoperatively. ERCP is effective for the majority of Strasberg A BDIs. For major and complex BDIs, hepaticocutaneous jejunostomy is a safe and effective approach.

Abstract
Endoscopic methods are nowadays a priceless tool for the treatment of postoperative complications after hepatobiliary, pancreatic and thoracic surgery. Endoscopic decompression of the biliary tract is the treatment of choice for biliary duct leakage after cholecystectomy, hepatic resection or liver transplantation. Postoperative biliary duct stenosis can also be successfully treated by endoscopic balloon dilatation and implantation of various endoprostheses in most of the patients. In the case of pancreatic fistulas, especially those occurring after central or distal pancreatic resections, endoscopic decompression of the pancreatic duct can significantly contribute to rapid healing. Additionally, interventional endosonography provides a valuable treatment option for transgastric drainage of postoperative fluid collections, which often accompany a pancreatic fistula. Various treatment alternatives have been described for the bronchoscopic treatment of bronchopleural and tracheoesophageal fistulas, which often lead to the rapid alleviation of symptoms and often to the definitive closure of the fistula.

Abstract
BACKGROUND AND STUDY AIM Bile duct injuries are not infrequently seen during hepatobiliary surgery, particularly after liver transplantation and cholecystectomy. The current study aims to figure out the frequency of postcholecystectomy biliary injuries (PCBI) and the role of early versus late endoscopic retrograde cholangiopancreatography (ERCP) in their management. PATIENTS AND METHODS Totally 960 cases operated by both laparoscopic and open cholecystectomy were evaluated in the current study. In total, 942 cases were operated in our institutes, by both laparoscopic (n = 925) and open (n = 17) cholecystectomy, and the frequency of PCBI among patients operated in our institutes was (9/942) 0.95%. Additional 18 cases of PCBI referred to our centers were included in the study. One patient was treated by repair during the surgery, in the remaining 26 patients, ERCP management was attempted. The full details of the 26 patients regarding ERCP management were discussed. RESULTS The overall success rate of ERCP management was 88.46% (23/26), whereas 11.54% of cases were treated surgically by choledochal-jejunal anastomosis due to complete common bile duct ligation. There were no differences between patients treated by early (first week) versus late (after the first week) ERCP regarding the needed interventions, type of PCBI, type and diameter of the inserted stents, and the overall success. There were no adverse events associated with ERCP management. CONCLUSIONS ERCP was valuable in the treatment of 88.46% of injured cases. There were no differences between early and late ERCP in the treatment of PCBI. Furthermore, ERCP management was not associated with adverse events.

Abstract
Abstract Performed on either an elective or urgent basis, cholecystectomy currently represents the most common abdominal operation due to the widespread use of laparoscopy and the progressively expanded indications. Compared to traditional open surgery, laparoscopic cholecystectomy minimised the duration of hospitalisation and perioperative mortality. Albeit generally considered safe, cholecystectomy may result in adverse outcomes with non-negligible morbidity. Furthermore, the incidence of worrisome haemorrhages and biliary complications has not been influenced by the technique shift. Due to the growing medico-legal concerns and the vast number of cholecystectomies, radiologists are increasingly requested to investigate recently operated patients. Aiming to increase familiarity with post-cholecystectomy cross-sectional imaging, this paper provides a brief overview of indications and surgical techniques and illustrates the expected early postoperative imaging findings. Afterwards, most iatrogenic complications following open, converted, laparoscopic and laparo-endoscopic rendezvous cholecystectomy are reviewed with examples, including infections, haematoma and active bleeding, residual choledocholithiasis, pancreatitis, biliary obstruction and leakage. Multidetector computed tomography (CT) represents the “workhorse” modality to rapidly investigate the postoperative abdomen in order to provide a reliable basis for an appropriate choice between conservative, interventional or surgical treatment. Emphasis is placed on the role of early magnetic resonance cholangiopancreatography (MRCP) and additional gadoxetic acid-enhanced MRCP to provide a non-invasive anatomic and functional assessment of the operated biliary tract. Teaching Points • Having minimised perioperative mortality and hospital stay, laparoscopy has now become the first-line approach to performing cholecystectomy, even in patients with acute cholecystitis. • Laparoscopic, laparo-endoscopic rendezvous, converted and open cholecystectomy remain associated with non-negligible morbidity, including surgical site infections, haemorrhage, residual lithiasis, pancreatitis, biliary obstruction and leakage. • Contrast-enhanced multidetector computed tomography (CT) is increasingly requested early after cholecystectomy and represents the “workhorse” modality that rapidly provides a comprehensive assessment of the operated biliary tract and abdomen. • Magnetic resonance cholangiopancreatography (MRCP) is the best modality to provide anatomic visualisation of the operated biliary tract and is indicated when biliary complications are suspected. • Additional gadoxetic acid (Gd-EOB-DTPA)-enhanced MRCP non-invasively provides functional biliary assessment, in order to confirm and visualise bile leakage.

Abstract
BACKGROUND AND STUDY AIMS A study was undertaken to describe the management of post-cholecystectomy biliary fistula according to the type of cholecystectomy. PATIENTS AND METHODS A retrospective analysis of 111 patients was undertaken. They were divided into open cholecystectomy (OC) and laparoscopic cholecystectomy (LC) groups. RESULTS Of the 111 patients, 38 (34.2 %) underwent LC and 73 (65.8 %) underwent OC. Endoscopic retrograde cholangiopancreatography (ERCP) diagnosed major bile duct injury (BDI) in 27 patients (38.6 %) in the OC group and in 3 patients (7.9 %) in the LC group (P = 0.001). Endoscopic management was not feasible in 15 patients (13.5 %) because of failed cannulation (n = 3) or complete ligation of the common bile duct (n = 12). Endoscopic therapy stopped leakage in 35 patients (92.1 %) and 58 patients (82.9 %) following LC and OC, respectively, after the exclusion of 3 patients in whom cannulation failed (P = 0 0.150). Major BDI was more commonly detected after OC (P < 0.001). Leakage was controlled endoscopically in 77 patients (98.7 %) with minor BDI and in 16 patients (53.3 %) with major BDI (P < 0.001). CONCLUSIONS Major BDI is more common in patients presenting with bile leakage after OC. ERCP is the first-choice treatment for minor BDI. Surgery plays an important role in major BDI. Magnetic resonance cholangiopancreatogrphy (MRCP) should be used before ERCP in patients with bile leakage following OC or converted LC.
