Endoscopic sphincterotomy and interval cholecystectomy are reasonable alternatives to index cholecystectomy in severe acute gallstone pancreatitis (GSP).
BACKGROUND
UK guidelines for gallstone pancreatitis (GSP) advocate definitive treatment during the index admission, or within 2 weeks of discharge. However, this target may not always be achievable. This study reviewed current management of GSP in a university hospital and evaluated the risk associated with interval cholecystectomy.


METHODS
All patients that presented with GSP over a 4-year period (2002-2005) were stratified for disease severity (APACHE II). Patient demographics, time to definitive therapy [index cholecystectomy; endoscopic sphincterotomy (ES); Interval cholecystectomy], and readmission rates were analysed retrospectively.


RESULTS
100 patients admitted with GSP. Disease severity was mild in 54 patients and severe in 46 patients. Twenty-two patients unsuitable for surgery underwent ES as definitive treatment with no readmissions. Seventy-eight patients underwent cholecystectomy, of which 40 (58%) had an index cholecystectomy, and 38 (42%) an interval cholecystectomy. Only 10 patients with severe GSP had an index cholecystectomy, whilst 30 were readmitted for Interval cholecystectomy (p = 0.04). The median APACHE score was 4 [standard deviation (SD) 3.8] for index cholecystectomy and 8 (SD 2.6) for Interval cholecystectomy (p < 0.05). Median time (range) to surgery was 7.5 (2-30) days for index cholecystectomy and 63 (13-210) days for Interval cholecystectomy. Fifty percent (19/38) of patients with GSP had ES prior to discharge for interval cholecystectomy. Two (5%) patients were readmitted: with acute cholecystitis (n = 1) and acute pancreatitis (n = 1) , whilst awaiting interval cholecystectomy. No mortality was noted in the Index or Interval group.


CONCLUSIONS
This study demonstrates that overall 62% (22 endoscopic sphincterotomy and 40 index cholecystectomy) of patients with GSP have definitive therapy during the Index admission. However, surgery was deferred in the majority (n = 30) of patients with severe GSP, and 19/30 underwent ES prior to discharge. ES and interval cholecystectomy in severe GSP is associated with minimal morbidity and readmission rates, and is considered a reasonable alternative to an index cholecystectomy in patients with severe GSP.
