Fluorescence angiography guided resection of small bowel neuroendocrine neoplasms with mesenteric lymph node metastases

#3102

Introduction: Surgery for small bowel neuroendocrine neoplasms (SB-NEN) might result in vascular compromise of the remaining bowel due to resection of lymph node metastases in close proximity to main mesenteric vessels. Fluorescence angiography (FA) has been described as a safe technique to assess perfusion during gastro-intestinal surgery.

Aim(s): This study aimed to evaluate the potential value of intraoperative FA during surgery for SB-NEN.

Materials and methods: This proof-of-concept-study included patients undergoing surgery for SB-NEN of any stage. The planned level of transection was marked by the surgeon, after which FA using indocyanine green (ICG) was performed. The primary study outcome was change in management due to FA.
