Laparoscopic cholecystectomy in children: A systematic review and meta-analysis

Laparoscopic cholecystectomy (LC) has become the procedure of choice for the removal of gallbladder within the paediatric population. The aim of this study was to perform a systematic review and meta-analysis of the literature spanning the last 20 years to understand the indications for and safety of LCs in children.

A comprehensive search of the published English language literature from January 2000 to June 2020 was done on PubMed, MEDLINE, and Google Scholar.

In total, 76,524 LC cases were identified from 114 studies. 78.9% of the patients were female and average age was 12 years old. Associated haematological disorders were identified in 16% of cases. The commonest indication for LC was cholelithiasis (68.4% in 66 studies), followed by cholecystitis (59.2% in 53 studies). Median operating time was 77 min. Median hospital stay was 2 days. The overall postoperative complication rate was 3.4% Major complications included bile duct injury (0.4%) and intra- or post-operative bleeding (0.9%). The conversion rate to open procedure was 2%. When comparing post-operative outcomes between emergency and elective admissions, three papers lent themselves to meta-analysis demonstrating no significant difference (p = 0.42). There was no statistically significant difference in postoperative complication rate between "hot" and "cold" laparoscopic cholecystectomies (p = 0.6).

This systematic review and meta-analysis is the largest collection of subjects on laparoscopic cholecystectomies in children. Laparoscopic cholecystectomy is a safe operation in children, with complication rates similar or comparable to the adult literature. Cholelithiasis, cholecystitis and biliary dyskinesia were the commonest indications for LC.
