Introduction: Any surgical procedure which would restore the bilio-enteric continuity after excision of the choledochal cyst with minimal complications would be a feasible alternative to Hepaticojejunostomy using a Roux loop of jejunum. To determine the outcomes of Hepaticoduodenostomy done over T-Tube against Roux-en-Y Hepaticojejunostomy for bilio-enteric reconstruction after excision of choledochal cyst.
Materials and Methods: This study was retrospectively done on all patients of choledochal cysts (Types 1 and 4) operated between January, 2014 and December, 2019. The clinical details, intra-operative and post-operative results of patients who underwent Roux-en-Y Hepatico-Jejunostomy (Group-1) and Hepatico-duodenostomy over T-Tube (Group -2) for establishing bilio-enteric continuity after excision of choledochal cyst were compared and analyzed statistically.
Results: 78 patients of choledochal cysts were operated during this period with 31 patients in Group-1 and 47 in Group-2; there was no difference in the mean age or size of the cysts in the two groups; Type 1 cysts were the most common with female preponderance in both groups. Group-2 patients had lesser intra-operative time andfewer numbers of sutures were used during surgery. There was no difference in the incidence of anastomotic leaks, strictures, cholangitis or adhesive obstruction and reoperation rates between the two groups. Group 2 showed increased nasogastric bilious aspirates in 19.15% of cases which improved on conservative management.
Conclusion: Bilio-enteric reconstruction using Hepaticoduodenostomy over T-Tube is a simpler, lower pressure and less time taking anastomotic technique with comparable complication rates when compared to Roux-en-Y Hepaticojejunostomy in the management of choledochal cysts.
