Factors affecting the operating time for complete cyst excision and Roux-en-Y hepaticojejunostomy in paediatric cases of congenital choledochal malformation: a retrospective case study in Southeast China.

Objective: The aim of this study was to evaluate factors affecting the operating time for complete cyst excision and Roux-en-Y hepaticojejunostomy in paediatric cases of congenital choledochal malformation (CCM).

Design: A 3-year retrospective study was undertaken between January 2013 and December 2015 in four centres in China.

Setting: This involved a retrospective chart review of paediatric patients with CCM in four large hospitals in Southeast China.

Participants: Sixty-five paediatric patients with CCM were included in this study. We derived all available information on patient demographics, clinical characteristics, preoperative complications and surgical methods from the charts of all these patients.

Interventions: Univariate and multivariate logistic regression analyses were used to evaluate factors significantly affecting the operating time for complete cyst excision and Roux-en-Y hepaticojejunostomy in paediatric cases of CCM.

Results: Twenty-three of the 65 case surgeries were performed using laparoscopic technique, and 42 surgeries were performed by conventional open surgery. The median operating time was 215 min (range 120-430 min). The morphological subtype of CCM and the presence of cholecystitis or cholangitis were the only factors found to affect the operating time (p<0.05). Logistic regression analysis confirmed cholangitis as an independent risk factor.

Conclusions: The morphological subtype of CMM and the presence of cholecystitis or cholangitis are factors affecting the operating time for complete cyst excision and Roux-en-Y hepaticojejunostomy in paediatric cases of CCM, whereas cholangitis is an independent risk factor.
