Robotic gastrointestinal stromal tumors surgery - initial results

Abstract

Introduction: Gastrointestinal stromal tumors (GISTs) usually present as an exophytic mass localized in stomach. Years ago, conventional surgery was the only option. Laparoscopic and robotic procedures have risen to prominence in recent decades as technology and surgical techniques have advanced. Aim: The aim of this study was to evaluate the safety and feasibility of robotic surgery of GIST. Materials and methods: All patients who underwent robotic surgery for a GIST in the University Hospital Kaspela-Plovdiv between November 2021 and April 2022 were included. Post-operative course and short oncological outcomes were analyzed. Results: Four patients with gastric GIST, median size 50 mm [40–70 mm], underwent robotic surgery. Conversion to open surgery not occurred. We have two cases with localization in corpus, one in antrum and one in the fundus. We have registered one complicationsanastomotic leakage after proximal resection treated conservatively. In others, the post-operative period was uneventful. The average hospital stay was 8.2 (4-11) days. The median operating time was 255 min (220–320 min). Conclusions: On basis of this initial results, we can conclude that robotic gastrointestinal tumors surgery is safe, feasible, and oncological sustained. Of course, one of the weakest sides of this surgery is prolonged operative time and increased expenses.
