Safety of laparoscopic cholecystectomy in patients with a cerebrospinal fluid shunt in the peritoneal cavity

Abstract

Introduction:The management of patients with a cerebrospinal fluid (CSF) shunt located in the peritoneal cavity undergoing laparoscopic surgery is an issue that has not yet been settled. These patients are at risk of increased intracranial pressure caused by peritoneal insufflation, shunt dysfunction, and shunt infection/retrograde meningitis. This study aimed to determine the need for perioperative shunt intervention in CSF shunt patients undergoing laparoscopic cholecystectomy. Methods: We reviewed and analyzed five shunt patients who underwent laparoscopic cholecystectomy in our institution between 2012 and 2022, as well as 17 patients described in previous reports.Results: Among the 22 patients, shunt type was ventriculoperitoneal in 14 and lumboperitoneal in eight. The most common indication for CSF shunt was hydrocephalus caused by cerebral vascular accident (50.0%). Laparoscopic cholecystectomy was performed for cholecystolithiasis in 13 patients (59.1%), acute cholecystitis in eight (36.4%), and gallbladder polyp in one (4.5%). Shunt clamping or externalization was performed in six patients. Two patients in the group that did not undergo shunt clamping or externalization experienced complications (intra abdominal abscess and subcutaneous emphysema). However, the incidence of short-term complications (both overall and shunt-related) and median length of hospital stay did not significantly differ between the two groups. Conclusion:Routine shunt clamping, externalization, or removal might not be necessarily required in patients with a ventriculoperitoneal or lumboperitoneal shunt undergoing laparoscopic cholecystectomy.
