Aim: A sigmoidectomy is the most definitive surgical treatment for recurrent diverticulitis. While it is usually accomplished via transabdominal specimen extraction and stapled anastomosis, the robotic platform can facilitate novel approaches and techniques. This is the first report of the initial experience using robotic sigmoidectomy with natural orifice specimen extraction and hand-sewn anastomosis (NOSHA)., Method: A prospectively maintained database of NOSHA procedures performed between 2018 and 2020 was retrospectively examined. The technique was described and variables across preoperative, intra-operative and postoperative timeframes were presented. The Clavien-Dindo classification system was used to describe postoperative complications., Results: Sixteen patients with recurrent diverticulitis treated with NOSHA were included in this study. Transanal specimen extraction and an intracorporeal hand-sewn anastomosis were achieved in all patients. However, two (12.8%) patients required specimen debulking prior to extraction. The mean operating time was 171.7 min, and patients had a return of bowel function within an average period of 35.2 h. The mean hospital length of stay was 2.9 days. In total, two (12.8%) complications were seen: one postoperative ileus managed conservatively and one readmission for abdominal pain which resolved without intervention. No anastomotic leaks or reoperations were observed., Conclusion: Robotic NOSHA appears to be a viable technique for the surgical management of diverticulitis. Further studies are needed to establish its utility for various diseases and its reproducibility across clinical practices., (© 2021 The Association of Coloproctology of Great Britain and Ireland.)
