Cold laparoscopic cholecystectomy is the gold standard for the management of symptomatic vesicular stones. There is considerable controversy as to whether it should be practiced in outpatient surgery or as part of inpatient surgery, regarding to patient safety.

"Minor" surgical procedures, such as anal surgery or simple inguinal hernia interventions, were initially considered eligible for an outpatient procedure. Advances in surgical techniques, anesthesia and early rehabilitation have also made it possible to consider more "heavy" interventions, such as cholecystectomy.

The aim of this study is to identify eligible patients for laparoscopic cholecystectomy in outpatient surgery, taking surgical criteria into account.

Inclusion Criteria:

• Patients who have had a laparoscopic cholecystectomy with a single cholecystectomy procedure without other associated interventions (bariatric surgery or other)

Exclusion Criteria:

• Pregnant women
• Diabetic patients under insulin treatment
• History of major abdominal surgery
• Acute cholecystitis as per anatomo-pathological examination

Patients who have had a laparoscopic cholecystectomy with a single cholecystectomy procedure without other associated interventions (bariatric surgery or other). Hospitalisation within the CHU Brugmann Hospital between May 2016 and November 2017.
