Modified laparoscopic excision of choledochal cyst: Technique and early results

Abstract

Background: Choledochal cyst is a common congenital anomaly requiring surgical treatment. Nowadays, laparoscopic excision is the preferred approach. We studied a modification in the classical laparoscopic approach to facilitate the dissection of a cyst. Materials and Methods: A prospective comparative study was done on 42 Type I choledochal cyst children. One group was operated by classical laparoscopic technique, while the other group was operated by modification of classical technique by deliberately opening the cyst wall and dividing the cyst into two hemi-cups, followed by dissection and excision. The intraoperative and postoperative parameters were assessed in both the groups. Results: The age, gender ratio, clinical presentation, and cyst diameter were comparable in both the groups. There was a significantly higher success rate (95.7% vs. 73.7%, P = 0.042) and lesser time for cyst excision (96.43 ± 12.15 vs. 120.91 ± 17.38 min P < 0.001) in the modified technique when compared to the classical technique. Further in three patients, it was possible to convert the classical procedure to a modified technique and complete the cyst excision. The postoperative outcomes were similar in both the groups. Conclusion: The modified laparoscopic excision shortens the operative time with higher success rate and comparable short-term morbidity vis-a-vis classical laparoscopic technique. © 2021 Journal of Indian Association of Pediatric Surgeons.
