Abstract

Background: Bile duct injury in cholecystectomy is a known complication with 0.1% incidence. There are many classifications system available for the same in literature. Case Report: The injury that we found and managed was out of any classification available. The entire biliary hilum with right and left hepatic ducts was in the specimen. We managed the patient with a two-stage approach. First, with drainage and second with reconstruction hepaticojejunostomy after 2.5 months. The patient is doing well at 8 years follow up. Conclusion: Intraoperatively detected complex bile duct injury carries a better outcome as compared to post-operatively detected bile duct injury.

Introduction

Bile duct injury in any variety of cholecystectomy is a known complication. Most of the time it arises out of misinterpretation of anatomy rather than a genuine variant of anatomy. Higher the injury at the level of hilum most difficult it is to treat. In literature search, we could not encounter any case with complete hilar injury extending up to second order biliary ducts and the whole biliary hilum was resected along with gall bladder specimen.

Case Report

A middle-aged male patient presented with acute cholecystitis, he was investigated and posted for laparoscopic cholecystectomy by a surgeon. During surgery, the surgeon encountered bile duct injury. He noticed the free flow of bile from the hilar area of the liver. He converted to open with right paramedian incision and intra-operatively telephone call was received. Upon examination, it was revealed that bile was coming from multiple areas within the hilum. The bile duct was not visible and along with that right hepatic artery was also not visible but the entire length of the portal vein was visible. Multiple clips were found on the lower end of CBD (common bile duct) and one clip on the right hepatic artery. The proximal end of CHD (common hepatic duct) was not appreciated hence decision to dissect the specimen was made.  In the specimen, we found gall bladder, CBD, the entire length of CHD, the confluence of the right and left duct up 2.5 cm on either side [Fig.1,2]




This injury of the bile duct cannot be classified with any of the available, existing classification systems. The injury was extending upto second order biliary ducts within the liver. We managed the patient with the multiple infant feeding tubes inserted in every sectoral duct: right anterior sectoral, right posterior sectoral, segment 4 duct, segment 2 duct and  segment 3 duct; and multiple drains in Morrison’s pouch [Fig.3]. The right hepatic artery was repaired with 8.0 prolene interrupted sutures. Post-operatively patient recovered with a controlled biliary fistula.  After 2.5 months, MRI with MRCP was done [Fig.4]. A wide hepaticojejunostomy (right and left separate) was done after 2.5 months of index surgery [Fig.5]. At 8 years follow up patient is doing well without any further issues. 








Discussion

Bile duct injuries along with hepatic artery injury should be managed in two stages [2]. Cannulation of sectoral ducts at the time of injury makes the second surgery a little easier especially of this variety. Bile duct injury when recognized intra-operatively carries a better outcome [3]. Misinterpretation of anatomy is more common than an anomaly in a biliary tree for bile duct injury [4]. Whenever, such a higher Strasberg injury is encountered, either an expert should be called or if the facility of such is not available then the patient should be either referred to a higher centre after placement of good wide bore, maybe multiple drains [5]. The patients with type E injuries are more difficult to manage as there is total loss of continuity, it takes long time to localize the fistula along with that it is associated with significant nutritional compromise, electrolyte imbalance, and long-term morbidity to carry the drains. The feeding jejunostomy for such patients is key factor for prevention of post-operative morbidity, especially in presence of complete biliary fistula [6]. Feeding tube avoids nutritional imbalances and enhances faster recovery of the patient. It maintains gut biliary flora barrier and hence digestion and absorption of fatty foods and fat soluble vitamins. Stenting prevents excessive peri bile duct inflammation, hence the stricture as well as its progression. It also makes the reconstruction during second surgery easier. Surgical treatment should be performed only when the patient is stabilized, and the BDI has been properly classified because the success of the operating procedure depends on the proper and accurate identification of the BDI [6].

Conclusion 

Intraoperatively detected complex bile duct injury carries a better outcome in comparison to post-operatively detected bile duct injury. Creation of controlled biliary fistula in emergency situation is a key to success in management of complex bile duct injury.
