A Single Centre Experience of Day Case Laparoscopic Cholecystectomy Outcomes by Body Mass Index Group.

Aim: The purpose of this study was to evaluate whether patients with a high BMI can undergo safe day case LC for cholecystitis compared to groups of patients with a lower BMI.

Setting: NHS District General Hospital, UK.

Methods: A retrospective review of 2391 patients who underwent an attempted day case LC between 1 January 2009 and 15 August 2015 was performed. Patients were divided into five groups depending on their BMI. Inclusion criteria were patients undergoing elective day case laparoscopic cholecystectomy with cholecystitis on histology. The endpoints were complication requiring readmission and postoperative length of stay (LOS).

Results: There were 2391 LCs performed in the time period of which 1646 were eligible for inclusion. These LCs were classified as 273 (16.9%), 608 (37.8%), 428 (26.6%), 208 (12.9%), and 91 (5.66%) patients in the groups with BMI values of 18.5-24.9, 25-29.9, 30-34.9, 35-39.9, and >40, respectively. Average BMI was 30.0 (±5.53, 19-51) with an average postoperative LOS of 0.86, and there was no difference between the BMI groups. Overall complication rate was 4.3%; there was no significance between BMI groups.

Conclusions: Increased BMI was not associated with worse outcomes after day case LC.
