Is there a place for endoscopic management in postcholecystectomy iatrogenic bile duct injuries?

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.

Post-cholecystectomy iatrogenic bile duct injuries:Emerging role for endoscopic management

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.

Iatrogenic extrahepatic bile duct injury in 182 patients: causes and management

Objective: To describe the causes and treatment ofiatrogenic bile duct injury caused by cholecystecto-my.Methods: 182 patients with iatrogenic extrahepaticbile duct injury from 4 university hospitals of Chinawere reviewed. Details of primary cholecystectomy,biliary reconstruction as well as postoperative ma-nagement were recorded. All patients were followedup for at least 6 months (6 months to 9 years, medi-an 3.5 years). The adequacy of repair was assessedby regular evaluation of the patients clinical statusand liver function variables. Hepatobiliary B-ultra-sonography was used routinely in the follow up of pa-tients, and magnetic resonance cholangiopancreatog-raphy was applied in the patients suggestive of abnor-mality.Results: In 152 patients, bile duct injury happenedduring open cholecystectomy, and in 30 patients dur-ing laparoscopic cholecystectomy. All the injuries de-veloped during anterograde cholecystectomy (at theCalot’s triangle). All the patients with these injuriesunderwent choledochocholedochostomy or Roux-en-Ycholedochojejunostomy with good results (161 pa-tients), recurrent stricture (11), and death (10).Conclusions: During cholecystectomy, the Calot’s tri-angle should be identified anatomically, but retro-grade cholecystectomy is the optimal choice. Bileduct injury should be discovered as soon as possibleand be managed timely. Different operative methodsare optional according to the degree of injury and thepostoperative period.

Pattern of Presentation of Iatrogenic Biliary Injury Following Laparoscopic Cholecystectomy

Background: Cholecystectomy is one of the most now common abdominal surgeries performed every day. The incidence of bile duct injury (BDI) following open cholecystectomy is only 0.1% - 0.2%. After the introduction of laparoscopic cholecystectomy, the incidence has gone up to 0.4% - 0.7%. The present study is a prospective analysis of all patients with bile duct injury who were admitted to Dhaka Medical College Hospital during or at a variable period following cholecystectomy. Methods: To determine the pattern of presentation of iatrogenic biliary injury following cholecystectomy in the department of surgery of Dhaka Medical College Hospital, a total of 30 patients were purposively selected from May 2018 to November 2018. Patient particulars, records of physical and clinical evaluation, and operative details were collected by individual researchers. Data analysis was done by SPSS for windows version 21. Results: BDI was found very common among the age group 21 - 30 yrs (36%) and female dominant (60%). Majority of the patients presented with abdominal pain (96%), intra-abdominal collection (88%), biliary peritonitis (68%), cholangitis (60%), and obstructive jaundice (40%), and biliary fistula (40%). Laparoscopic cholecystectomy (84%) was the principal cause of biliary injury in our study. 48% of patients experienced clinical features within 7 days post-cholecystectomy. Per-operative diagnosis was done in only 12% of cases. 44% of patients in this study were recognized as Bismuth grade-3, followed by 36%, grade-2 patients. Management outcomes included wound infection (41.66%), minor bile leak (25%), peritonitis (8.33%), and renal impairment (8.33%). Conclusion: The effect of BDI is an extremely distressful clinical condition for the patients and their family members, hence proper care and management protocol should be followed.

Iatrogenic bile duct injuries:Etiology,diagnosis and management

Iatrogenic bile duct injuries (IBDI) remain an important problem in gastrointestinal surgery. They are most frequently caused by laparoscopic cholecystectomy which is one of the commonest surgical procedures in the world. The early and proper diagnosis of IBDI is very important for surgeons and gastroenterologists, because unrecognized IBDI lead to serious complications such as biliary cirrhosis, hepatic failure and death. Laboratory and radiological investigations play an important role in the diagnosis of biliary injuries. There are many classifications of IBDI. The most popular and simple classification of IBDI is the Bismuth scale. Endoscopic techniques are recommended for initial treatment of IBDI. When endoscopic treatment is not effective, surgical management is considered. Different surgical reconstructions are performed in patients with IBDI. According to the literature, Roux- en-Y hepaticojejunostomy is the most frequent surgical reconstruction and recommended by most authors. In the opinion of some authors, a more physiological and equally effective type of reconstruction is end- to-end ductal anastomosis. Long term results are the most important in the assessment of the effectiveness of IBDI treatment. There are a few classifications for the long term results in patients treated for IBDI; the Terblanche scale, based on clinical biliary symptoms, is regarded as the most useful classification. Proper diagnosis and treatment of IBDI may avoid many serious complications and improve quality of life.

Iatrogenic bile duct injuries from biliary tract surgery

BACKGROUND:Cholecystectomy is the most commonly performed procedure in general surgery.However,bile duct injury is a rare but still one of the most common complications.These injuries sometimes present variably after primary surgery.Timely detection and appropriate management decrease the morbidity and mortality of the operation. METHODS:Five cases of iatrogenic bile duct injury(IBDI) were managed at the Department of Surgery,First Affiliated Hospital,Xi’an Jiaotong University.All the cases who underwent both open and laparoscopic cholecystectomy had persistent injury to the biliary tract and were treated accordingly. RESULTS:Recovery of the patients was uneventful.All patients were followed-up at the surgical outpatient department for six months to three years.So far the patients have shown good recovery. CONCLUSIONS:In cases of IBDI it is necessary to perform the operation under the supervision of an experienced surgeon who is specialized in the repair of bile duct injuries,and it is also necessary to detect and treat the injury as soon as possible to obtain a satisfactory outcome.

Initial management of suspected biliary injury after laparoscopic cholecystectomy

Although rare,iatrogenic bile duct injury(BDI)after laparoscopic cholecystectomy may be devastating to the patient.The cornerstones for the initial management of BDI are early recognition,followed by modern imaging and evaluation of injury severity.Tertiary hepato-biliary centre care with a multidisciplinary approach is crucial.The diagnostics of BDI commences with a multiphase abdominal computed tomography scan,and when the biloma is drained or a surgical drain is put in place,the diagnosis is set with the help of bile drain output.To visualize the leak site and biliary anatomy,the diagnostics is supplemented with contrast enhanced magnetic resonance imaging.The location and severity of the bile duct lesion and concomitant injuries to the hepatic vascular system are evaluated.Most often,a combination of percutaneous and endoscopic methods is used for control of contamination and bile leak.Generally,the next step is endoscopic retrograde cholangiography(ERC)for downstream control of the bile leak.ERC with insertion of a stent is the treatment of choice in most mild bile leaks.The surgical option of re-operation and its timing should be discussed in cases where an endoscopic and percutaneous approach is not sufficient.The patient's failure to recover properly in the first days after laparoscopic cholecystectomy should immediately raise suspicion of BDI and this merits immediate investigation.Early consultation and referral to a dedicated hepatobiliary unit are essential for the best outcome.

Iatrogenic Bile Duct Injuries after Cholecystectomy, Is the Laparoscopic Approach a Good Idea?

Objective: The treatment of iatrogenic bile duct injuries is still a challenge for hepatobiliary and general surgeons. Roux-en-Y hepaticojejunostomy, one of the most appropriate techniques for the treatment of circumferential lesions, either occurring less than 2 cm from the bifurcation or in the bifurcation of the common hepatic duct, requires experience in advanced laparoscopy and hepatobiliary surgery. This study aims to present the results of laparoscopic hepaticojejunostomy (LHJ) for the treatment of iatrogenic bile duct injuries (IBDI). Methods: A retrospective study analyzing the medical records of patients diagnosed with IBDI and treated using LHJ of patients at the Hospital S?o José do Avaí (HSJA). Sex, age, previous cholecystectomy technique, signs and symptoms, postoperative complications, length of stay, injury classification, and time elapsed from injury to diagnosis were analyzed. Magnetic resonance cholangiography (MRC), endoscopic retrograde cholangiopancreatography (ERCP) or intraoperative cholangiography. Results: From March 2006 to December 2018, six patients underwent LHJ. In five cases (83.33%), the primary operation was a laparoscopic cholecystectomy (LC) and in one patient (13.66%) open cholecystectomy. The most frequent clinical sign was jaundice. The mean surgical time was 153.2 minutes (range: 115 to 206 minutes), and the hospital stay was 3 to 7 days (mean: 4.16 days). One patient had infection of the umbilical trocar incision and one patient presented with stenosis of the hepaticojejunal anastomosis and was treated with radioscopic pneumatic dilatation. Conclusion: LHJ for circumferential and total IBDI either diagnosed early (during surgery) or late, may be a safe and effective option, with similar results to the conventional technique, a low complication rate and all the known advantages of minimally invasive surgery.
