Prophylactic Cholecystectomy is Not Mandatory in Patients Candidate to the Resection for Small Intestine Neuroendocrine Neoplasms: a Propensity Score-matched and Cost-minimization Analysis

March 2, 2021 updated by: Carlo Ingaldi, MD, IRCCS Azienda Ospedaliero-Universitaria di Bologna
To evaluate two competitive strategies in patients undergoing resection of Small-intestine Neuroendocrine neoplasms (Si-NEN): Prophylactic Cholecystectomy (PC) versus On-demand delayed cholecystectomy

Detailed Description

This is a retrospective study based on 230 Si-NENs candidates to the primary tumor resection. Patients were divided into two arms: PC and OC. Propensity score matching was performed, reporting the d value. The primary outcome was the re-hospitalization rate for any cause. The secondary endpoints were the re-hospitalization rate for biliary stone disease (BSD), the mean number of re-hospitalization (any cause and BSD), the complication rate (all and severe), and the total costs. A P-value < 0.05 was considered significant, and NNT< 10 was considered clinically relevant.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Ages Eligible for Study

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

For each patient sex, age, comorbidity, presence of symptoms, type of surgery (emergency or elective), ENETS TNM stage, WHO 2019 grading of the primary tumor, type of resection (R0/1 vs. R2), administration of SSA therapy, duration of follow-up, were collected

Description

Inclusion Criteria:

  • patients with a diagnosis of Si-NEN;
  • resection of the primary tumor with or without concomitant cholecystectomy;
  • absence of a history of a biliary stone disease or cholecystectomy before Si-NEN diagnosis

Exclusion Criteria:

- presence of a history of a biliary stone disease or cholecystectomy before Si-NEN diagnosis
