Timing of CHolecystectomy In Severe PAncreatitis

Laparoscopic cholecystectomy will be performed using the standard American 4-port technique, insufflation will be achieved using CO2 to 15mmHg of pressure. Calot's triangle will be dissected until the critical view of safety is reached, being careful to dissect above the R4U line. After reaching the critical view of safety, two proximal and one distal clip will be placed on both the cystic conduct and artery separately, cutting the clips and then dissecting the gallbladder in a cystfundic direction. When the critical view of safety is not reached, the surgeon may perform a fundus-first cholecystectomy, subtotal cholecystectomy, conversion to open procedure, intraoperative cholangiography or cholecystostomy to their own discretion. It will also be the surgeon's criteria to employ or not a drain system in the surgical site. The decision for theses interventions will be taken intraoperatively and will be according to findings during the procedure.
