Study of Operative Events and Time Requirement of Hepaticoduodenostomy for the Treatment of Type I Choledochal Cyst- the Experience at BSMMU Hospital.

Of all varieties, Type I Choledochal cyst causing saccular or fusiform dilatation of the extra-hepatic biliary ductal system is the commonest (90.0 - 95.0%). Its presentations vary. To restore the continuity of the extra-hepatic biliary tract after excision of type I Choledochal cyst, surgeons have few alternatives to use, with their advantages and disadvantages. Roux en-Y Hepatico-jejunostomy (RYHJ) has been very popular and long studied standard surgical treatment for type I Choledochal cyst. But now Hepatico-duodenostomy (HD) is also being practiced and studied in different centers all over the world for the treatment of the same disease. For the last five years, we, at Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh, have been using Hepatico-duodenostomy as preferred anastomotic option in treating type I Choledochal cyst. Here, we are presenting our experience at BSMMU Hospital, regarding operative events and time requirement of Hepaticoduodenostomy for the treatment of type I Choledochal cyst and, to show whether this procedure can be safely practiced, producing acceptable results. It is a retrospective document study, from January 2013 to December 2017, at BSMMU Hospital, on forty two, MRCP confirmed type I Choledochal cyst patients of pediatric age. Patients' particulars, history, physical examination, investigations (including MRCP confirmation), assessment, surgical plan were collected from relevant medical records and documented in duly coded individual data collection sheet maintaining standard privacy protocol. Information regarding presentations, operative findings and procedural events including per-operative mortality, injury to the vital structures during operation, conversion to RYHJ, operative time (minutes), blood loss and transfusion requirements (ml) of Heaticoduodenostomy for type I Choledochal cyst, were specially searched for. There was no operative mortality. None of these patients required per-operative blood transfusion. Nor there was any inadvertent injury to the adjacent structures. The mean operative time required for Hepaticoduodenostomy was 88 minutes with a range of 75 to 125 minutes. Through this study, at BSMMU Hospital, operative events and time requirement of Hepatico-duodenostomy for treating type I Choledochal cyst, was found to be yielding acceptable results, for safe practice.
