Overview
The goal of this clinical trial is to compare outcomes for interval or early laparoscopic cholecystectomy in patients with moderately severe and severe pancreatitis. The main question[s] it aims to answer are:
- To establish whether there is a difference in surgical outcomes comparing patients diagnosed with severe or moderately severe pancreatitis on which early cholecystectomy was performed versus performing interval cholecystectomy.
- The primary endpoint will be to evaluate major complications, defined as a Clavien-Dindo score greater than or equal to III/V.
- Secondary endpoints include evaluating minor complications (defined as a Clavien-Dindo score below III/V), biliary disease recurrence, mortality, postoperative hospital stay and postoperative admittance into an intensive care unit.
Participants will be randomly assigned to either group: early cholecystectomy during the pancreatitis hospitalization or interval cholecystectomy scheduled 4 weeks after clinical resolution of pancreatitis.
Description
CHISPA is a randomized controlled, parallel-group, superiority clinical trial. An intention- to-treat analysis will be performed. It seeks to evaluate differences between patients taken to early cholecystectomy during hospital admission (72 hours after randomization) versus delayed cholecystectomy (30 +/- 5 days after randomization). Primary endpoint is major complications associated to laparoscopic cholecystectomy defined as a Clavien-Dindo score of over III/V during the first 90 days after the procedure. Secondary endpoints include recurrence of biliary disease, mortality, minor complications (Clavien-Dindo score below III/V), days of postoperative hospital stay, and days admitted in an intensive care unit postoperatively.
Eligibility
Inclusion Criteria:

Exclusion Criteria:
- Pregnancy
- History of cholecystectomy
- Planned open cholecystectomy
- Pancreatitis-associated complication before laparoscopic cholecystectomy (compartment syndrome, bleeding and/or need for peripancreatic collection drainage)
- Chronic pancreatitis,
- More than one episode of pancreatitis
- Active malignant disease
- Septic shock
- Choledocholithiasis not resolved by ERCP, post-ERCP perforation and post-ERCP concomitant pancreatitis.
