Hepatico-jejuno-duodenal access loop – a modified biliary reconstruction technique for facilitated endoscopic access to biliary tree following surgery for hepatolithiasis


 Aims: Management of hepatolithiasis is complicated by residual and recurrent disease, and endoscopic access to biliary tree in such patients enables therapeutic interventions thereby avoiding the morbidity associated with relaparotomy. In this study we assess a modified biliary reconstruction in the form of hepaticojejuno- duodenal access loop (HJDA) with regard to the feasibility of endoscopic access to intrahepatic ducts with follow-up.

 Methods: From August 2011 till December 2016, all patients treated for hepatolithiasis with bilateral disease, nondilated extrahepatic biliary system or extensive intrahepatic strictures underwent HJDA. After completion of hepaticojejunostomy (HJ), the free end of the Roux loop was anastomosed to the first part of duodenum in a side to side fashion. In the fourth week postoperatively, endoscopy with conventional forward viewing endoscope was performed to explore the possibility of accessing the biliary system.

 Results: Endoscopic access to the intrahepatic bile ducts through the HJDA was possible in all the patients and mean time taken to access the HJ was 3.5 minutes (2-7 minutes). There were no complications pertinent to construction of the HJDA. One patient had bile leak from HJ, which settled with conservative management and surgical site infection was seen in four. We did not have any mortality in our series. During the follow up, three of our patients (30%) subsequently presented with cholangitis at a mean period of 22 months and were successfully managed with endoscopic procedures alone. One patient required balloon dilatation of the HJ stricture, while the other two were managed by endoscopic removal of calculi. Overall, five endoscopic procedures were required in three patients with recurrent cholangitis in the follow up period with rate of 1.67 procedures per patient.

 Conclusion: HJDA is a modified biliary reconstruction technique which facilitates endoscopic access to the biliary system for removal of recurrent/residual intrahepatic stones. It is therefore recommended in patients with complicated hepatolithiasis like bilateral disease, recurrence, multiple intrahepatic strictures and for those in whom future endoscopic access to biliary tree is deemed necessary.
