Bile duct injury continues to occur at an unacceptable rate in laparoscopic cholecystectomy despite efforts to promote safe surgery.
A 73-year-old male underwent attempted laparoscopic cholecystectomy that led to an E1 biliary injury. An immediate intraoperative cholangiogram was performed, confirming the injury. Consultation with a hepatobiliary surgeon advised to stop further resective surgery and transfer the patient a hepatobiliary center. The patient underwent definitive repair within 24 hours and was found to have an E1 injury as well as aberrant anatomy, where the right posterior section duct inserted low on the common bile duct just above the biliary injury. Leaving the gallbladder in situ not only avoided further injury to the common hepatic duct, but prevented injury or damage to the aberrant duct, which could have resulted in greater morbidity and mortality. Repair was performed with a Hepp-Couinaud Roux-en-Y hepaticojejunostomy and the patient had no short- or long-term (5.2 year follow-up) complications. The patient was very satisfied with their care and no medical-legal action was pursued.
General surgeons performing laparoscopic cholecystectomy should initiate a pause as soon as a biliary injury is suspected. Avoiding any further harm, including worsening a possible existing injury, should be standard practice and the goal of any surgeon.
Bile duct injury, laparoscopic cholecystectomy, biliary reconstruction, patient safety
We present the case of a 73-year-old male undergoing an attempted laparoscopic cholecystectomy that led to an E1 biliary injury. The surgeon at an outside hospital reported encountering dense adhesions and inflammation at the base of the gallbladder. He dissected, clipped, and cut what he believed to be the cystic duct and continued his dissection. He unfortunately encountered bile and a new lumen. A cholangiogram was obtained, demonstrating he had likely transected the common bile duct. Suspecting this biliary injury, the resective surgery was stopped and our facility was called for an intraoperative consultation with a hepatobiliary surgeon. Our team advised the surgeon to leave the gallbladder in situ, place a drain, and transfer the patient to our facility immediately. The surgeon agreed to this plan and we received the patient rapidly.
On arrival, the patient was hemodynamically stable. Past medical history was significant for hypertension, hyperlipidemia, obesity, type II diabetes, and gastroesophageal reflux disease. He had no prior surgeries. We obtained labs, which revealed a mild leukocytosis, normal hematocrit, normal liver function tests and total bilirubin. He was consented and taken to the operating room. We opened the abdomen via a right subcostal incision with midline extension. The patient was found to have a Strasberg type E1 biliary injury. This injury follows the known classic bile duct injury pathway (Figure 1), where the distal common bile duct is thought to be the cystic duct and is transected. Then, dissection is carried along the left and posterior side of the common hepatic duct and the duct is encountered again more superiorly and transected, resulting in a loss of biliary tissue spanning that segment. This classic pattern is often associated with vasculobiliary injury, most commonly injury to the right hepatic artery, and, thus, ceasing further surgery may be preventive.1 In this case, however, the surgery stopped prior to causing a secondary injury to the common hepatic duct or associated vascular injury.
Figure 1. This classic bile duct injury occurs when the distal common bile duct is mistaken as the cystic duct and transected. 2. The left side of the common duct is believed to be the underside of the gallbladder and dissected further. 3. Then as the surgeon carries the dissection from the patient’s left to right, the common hepatic duct is transected and a biliary injury is then suspected.
Intraoperatively, we found the gallbladder remained in situ with multiple gallstones and obliteration of the cystohepatic window (Mirizzi syndrome) to the side of the common bile duct due to associated inflammation. A cholangiogram was obtained confirming a transected common bile duct just above the cystic duct (Figure 2).

We also identified aberrant anatomy with the right posterior section duct of segment 6 draining directly into the common hepatic duct just above the biliary injury (Figure 3).

Stopping the surgery not only allowed for preserving the common hepatic duct, but also saved the patient potential injury to the low inserting right posterior section duct. If dissection continued in an attempt to remove the gallbladder, the injury may have extended to an E3 or E4 injury with transection or resection of the right posterior section duct. This would have significantly complicated the repair and the patient may have required ligation of the resected aberrant right sectional duct, resulting in higher risk for long-term stricturing (Figure 4).

After removing the gallbladder and clearing all stones, we performed a Hepp-Couinaud Roux-en-Y hepaticojejunostomy to the common bile duct at the level of the right posterior duct insertion. The lumen measured approximately 2.5cm. The transected distal common bile duct was clipped by the transferring surgeon and we left this alone. Two drains were placed to monitor for bile leak post operatively. The final pathology demonstrated chronic cholecystitis with wall thickening and congestion in addition to cholelithiasis.
The patient recovered well with no evidence of bile leak and his drains were discontinued prior to discharge home on postoperative day five. At his four-week follow-up visit, he had returned to normal activities, tolerated a normal diet, and had only a mildly elevated alkaline phosphatase with normal liver function tests otherwise. He has had no evidence of biliary obstruction, stricture, or complications at 5.2-year follow-up. It is important to note that the patient was very satisfied with his care by his original surgeon. He even chose to have his follow-up with the first surgeon in order to avoid travel and time away from home.
Bile duct injuries continue to occur in laparoscopic cholecystectomy even after more than two decades have passed since the procedure was introduced. A number of proposed methods of safety have been employed with various approaches to confirming and/or documenting biliary anatomy.2-6 The critical view of safety approach is indeed protective but has variable understanding and use by practicing surgeons.7-10 In addition, evidence supports that the critical view of safety approach is not the only safe method and that attempting to complete a critical view of safety can lead to biliary injury in densely inflamed tissue or in the case of aberrant anatomy.11,12 We also know that converting to an open cholecystectomy may lead to more complex injury in unskilled hands or those less familiar with complicated laparoscopic cholecystectomy.13 Proposed surgeon competencies and algorithms for safe cholecystectomy have attempted to create a framework to avoid bile duct injuries.14,15 Despite these efforts, it is still common for hepatobiliary surgeons to accept high-level bile duct injuries, for operative management and reconstruction.
To our knowledge, a case of bile duct injury in which the surgeon stopped resective surgery and the gallbladder was left in situ has not been reported in the literature. Because this phenomenon cannot be easily studied, we demonstrate that the patient in this case was likely spared significant morbidity because the transferring surgeon wisely stopped and reassessed the situation when injury was suspected rather than completing the cholecystectomy. From our experience, this is usually not the case and patients with biliary injury most often arrive without their gallbladder and higher levels of injury, thus requiring more complex operative repair. A review of biliary injury in 112 patients found that 71.6% of biliary injuries were E2–E5 and not one patient with an E1 injury had long-term complications.16 Personal communication with Strasberg, the primary author, reported that not one of the biliary injuries referred to their facility arrived with a gallbladder in situ. This is likely why high-level injuries occur.
E1 injuries have the best long-term outcomes, least risk of stricture, and least risk of concomitant vasculobiliary injury. It is indeed our current advice and teaching to all surgeons that perform laparoscopic cholecystectomy that when a bile duct injury is suspected, a pause should be initiated. Importantly, if an injury is identified and a qualified colleague is available, immediate intraoperative consultation should be initiated to assist with collaborative decision-making and reconstruction, if appropriate. What happens after that pause depends on the surgeon’s ability and resources, as well as adhering to the foundation of medicine to do no harm or, in some cases, do no further harm.
This case suggests that avoiding further resective surgery likely results in less severe biliary injury, better long-term outcomes, and more satisfied patients. It is time to change the culture of safe cholecystectomy to include stopping surgery when one suspects a bile duct injury and, thus, avoiding a secondary injury to the biliary system.17,18
Biliary injury is a highly morbid event in laparoscopic cholecystectomy. Leaving the gallbladder in situ and abandoning the perceived need to complete the laparoscopic cholecystectomy may prevent higher grades of biliary injury and reduce harm to patients.
