Ultrasound-Guided Robotic Enucleation of Pancreatic Neuroendocrine Tumors.

ABSTRACT

BACKGROUND: Pancreatic neuroendocrine tumors (PanNETs) are relatively rare neoplasms with a low to mild malignant potential. They can be further divided into functioning and nonfunctioning, according to their secretive activity. Surgery is an optimal approach, but the classic open approach is challenging, with some patients having long hospitalization and potentially life-threatening complications. The robotic approach for PanNETs may represent an option to optimize their management. METHODS: We retrospectively reviewed our prospectively maintained databases from 2 high-volume Italian centers for pancreatic surgery. Demographics, pathological characteristics, perioperative outcome, and medium-term follow-up of patients who underwent robotic pancreatic enucleations were collected. RESULTS: Twelve patients with final diagnosis of PanNET were included. The mean age of the patients was 53.8 years (25-77). The median body mass index was 26 (24-29). Three lesions were functioning insulinomas, while the others were nonfunctioning tumors. No deaths occurred. Mild postoperative complications occurred, except for 1 grade B pancreatic fistula. The mean postoperative stay was 3.9 days (2-5). CONCLUSIONS: Our results confirm that robotic enucleation is a feasible and safe approach for the treatment of PanNETs, with short hospital stay and low incidence of morbidity.
