Value of laparoscopy for resection of small bowel neuroendocrine neoplasms including central mesenteric lymphadenectomy

#3101

Introduction: Literature on laparoscopic resection of small bowel neuroendocrine neoplasms consists of single case descriptions or small selected case-series only, likely because of challenging mesenteric lymphadenectomy.

Aim(s): We evaluated an institutional change in approach from open to laparoscopic resection of SB-NEN independent from lymph node involvement.

Materials and methods: This is a retrospective comparative cohort study conducted at a tertiary referral center. Patients with small bowel neuroendocrine neoplasms who underwent laparoscopic or open segmental bowel resection with central mesenteric lymphadenectomy were included. Complexity of lymphadenectomy was assessed by determining distance between suspect lymph nodes and main mesenteric branches on preoperative CT. Number of (tumor-positive) lymph nodes, conversion to open surgery, post-operative complications according to Clavien-Dindo and length of stay.
