Biliary-enteric reconstruction with hepaticoduodenostomy following laparoscopic excision of choledochal cyst is associated with better postoperative outcomes: a single-centre experience

With the advent of laparoscopic surgery, more choledochal cysts are excised laparoscopically. In this study, we compared the outcomes from laparoscopic hepaticojejunostomy (HJ) and hepaticoduodenostomy (HD) for biliary-enteric reconstruction.

A retrospective analysis of patients who had undergone laparoscopic choledochal cyst excision between February 2005 and January 2014 in a tertiary referral centre was performed. Demographics data, operative techniques and surgical outcomes were analysed according to the way of biliary-enteric reconstruction.

A total of 31 patients were identified, 20 of whom underwent HJ and 11 underwent HD. There were no significant differences in terms of demographics. Median operative time was significantly shorter in HD group (211.0 ± 96.4 vs. 386.0 ± 90.4 min, p = 0.001). Although postoperative enteral feeding was initiated later in HD group (5.0 ± 0.8 vs. 4.0 ± 3.6 days, p = 0.036), postoperative stay in intensive care unit (ICU) (0.7 ± 1.0 vs. 2.4 ± 1.7 days, p = 0.007) and overall hospital stay (9.1 ± 1.0 vs. 14.4 ± 12.2 days, p = 0.157) favoured HD group. There was no perioperative mortality. Median follow-up duration was 24.0 (±11.0) months in HD group and 67.5 (±23.7) months in HJ group. One patient in HJ group had postoperative cholangitis related to anastomotic stricture whereas no cholangitis noted in HD group. In total, five patients in HJ group required second operation for complications and residual diseases whereas none in HD group required reoperation.

Laparoscopic excision of choledochal cyst with hepaticoduodenostomy reconstruction is safe and feasible with shorter operative time, ICU stay and overall hospital stay. It is not inferior to HJ in terms of short-term postoperative outcomes.
