Brief Summary

The investigators want to study the effectiveness of prophylactic cholecystectomy in patients with midgut neuroendocrine tumor (jejunum, ileum or proximal colon) who require primary tumor surgery. When patients are diagnosed and are tributary to surgical treatment, the tumor might compromise vascularization, and patients need an extensive bowel resection. The patients might also receive medical treatment with somatostatin analogs. The combination of extensive bowel resection and medical treatment might increase gallbladder stones, but patients might not develop biliary stone disease, as in the general population, where 20% of the population have gallbladder stones but only a 10 to 15 % of the population will develop symptoms. The idea comes from the lack of literature about the incidence of biliary Stone disease in patients with midgut NET tumors. It's a multicentric, open-label and randomized clinical trial to evaluate the incidence of biliary stone disease in patients with midgut NET who require primary tumor surgery combined or not to cholecystectomy. Our hypothesis suggests that patients with midgut neuroendocrine tumor who require primary tumor resection without the combination of prophylactic cholecystectomy do not have an increased incidence of biliary stone disease two years after the surgery, regardless of treatment with SSA.

Outcome Measures

Primary Outcomes (1)

  • To evaluate the rate of biliary stone disease associated to patients with midgut NET that have gone through primary tumor surgery.

    Incidence of biliary stone disease in patients with midgut NET who requiere primary tumor surgery

    Two years after the surgery

Secondary Outcomes (6)

  • To assess the incidence of post-operative complications until day 28 +/- 3 (1 Month) after the surgery.

    One month after the surgery

  • To assess the incidence of: anastomotic dehiscence, wound infection, reoperation.

    One month after the surgery

  • To evaluate the incidence of gallstone in patients who require a bowel resection and/or ileocecal junction resection.

    Two years after the surgery

  • To evaluate de incidence of gallstones in patients who will receive medical treatment with SSA

    Two years after the surgery

  • To describe bowel movements of patients after the surgery.

    Two years after the surgery

  • +1 more secondary outcomes
