Prophylactic cholecystectomy at time of surgery for small bowel neuroendocrine tumor (SBNET) has been advocated, as these patients often go on to require somatostatin analogue therapy, which is known to increase risk of cholestasis and associated complications. Little is known regarding patterns of adoption of this practice or its associated morbidity.


The American College of Surgeons National Surgical Quality Improvement Program database (2008–2014) was queried to identify patients who underwent SBNET resection. The risk differences of morbidity and mortality associated with performance of concurrent cholecystectomy were determined with multivariable adjustment for confounders.


Among 1300 patients who underwent SBNET resection, 144 (11.1%) underwent concurrent cholecystectomy. Median age of patients undergoing cholecystectomy was 62 years [interquartile range (IQR) 52–69 years], and 75 were male. They more commonly had disseminated cancer (36.1 vs. 11.6%, p < 0.001) or SBNET located in duodenum (10.4 vs. 4.9%, p = 0.045) without difference in other baseline characteristics. Operative time was significantly longer in the cholecystectomy group (median 172 vs. 123 min, p < 0.001). Rate of postoperative morbidity was not significantly different between cholecystectomy and no-cholecystectomy groups (11.8 vs. 11.1%, p = 0.79). After adjustment for confounding, the risk difference of morbidity attributable to cholecystectomy was + 0.4% [95% confidence interval (CI) − 4.9 to + 5.6%]. Mortality within 30 days was not significantly different between cholecystectomy and no-cholecystectomy groups (1.4 vs. 0.6%, p = 0.29).


Concurrent cholecystectomy at time of resection of SBNET is not associated with higher morbidity or mortality yet is performed in a minority of patients. Prospective study can identify which patients may derive benefit from this approach.
