Management of choledochal cyst: Evolution with antenatal diagnosis and laparoscopic approach.

BACKGROUND/AIM: Laparoscopic excision of a choledochal cyst (CC) with hepaticojejunostomy gained a wide acceptance in the treatment of children even in neonatal period. Although, the use of prenatal diagnostic techniques causes a significant increase in antenatal diagnosis of CC, the time of surgical intervention during infancy is still controversial. A retrospective study was performed to evaluate the results of laparoscopic management of CC with special emphasis on antenatal diagnosis and treatment, and to compare the results with open procedure.

MATERIALS AND METHODS: The patients who were diagnosed with choledochal cyst and underwent either open or laparoscopic hepaticojejunostomy in two centres, hopital d'enfant de La Timone from Marseille and hopital Robert Debre from Paris between November 2000 and December 2009 were included in the study. The data obtained from medical reports were evaluated for sex, time of antenatal diagnosis, age at time of operation, operative time, time of postoperation.

RESULTS: A total of 19 hepaticojejunostomy were performed, including 10 open procedures (group A), and 9 laparoscopic procedures (group B, 4 were diagnosed prenatally, without conversion to open procedure). There were 3 boys and 16 girls, ranging in age from 2 weeks to 16 years. Patients in the group A were older than patients in the group B. The mean hospital stay and time to return of bowel fuction was longer in the group B. there were 60% of pre-operative complications in group A versus 22% in group B. There was one postoperative complications in group B (biliary leakage nedeed redo surgery). No significant differences were found between different parameters except for operative time (288.56 min in the group B versus 206 min in the group A. (p = 0.041)).

CONCLUSIONS: Our initial experience indicates that the laparoscopic approach in infancy is technically feasible, safe, and effective, with a low morbidity and a comparable outcome to the open approach. Therefore, we propose a laparoscopic approach for antenatally diagnosed CC as early as possible, before the onset of complications.
