Gallbladder Stones in Pediatric Age: An Emerging Problem: The Risk of Difficult Cholecystectomy and the Importance of a Preoperative Evaluation

Abstract

The need for cholecystectomy during pediatric age has significantly increased in the last two decades. As biliary pathology increases, the probability of complicated cholecystectomies increases too. The aim of this article is to analyze our experience with difficult laparoscopic pediatric cholecystectomy, focusing on the importance of an accurate pre-operative imaging study. We retrospectively analyzed all patients affected by cholelithiasis who underwent laparoscopic cholecystectomy at the Pediatric Surgery Department of San Camillo Forlanini hospital of Rome and Santa Maria alle Scotte University Hospital of Siena from 2017 to 2022. Demographic data, body mass index (BMI), recovery data, laboratory tests, imaging exams, surgical findings, post operative management and outcome were taken into account. Overall, 34 pediatric patients, with a mean age of 14.1 years (6–18 years) were included, with a mean BMI of 29. All patients underwent abdominal ultrasonography and a liver MRI with cholangiography (cMRI). We identified five cases as “difficult cholecystectomies”. Two subtotal cholecystectomies were performed. Cholecystectomy in pediatric surgery can be difficult. The surgeon must be able to find alternative strategies to total cholecystectomy to avoid the risk of possible bile duct injury (BDI). Pre-operative imaging study trough ultrasound and especially cMRI is crucial to recognize possible difficulties and to plan the surgery.
