Robotic Assisted Transanal Polypectomies: Is There Any Indication?

Abstract Objectives Robotic assisted transanal polipectomy may have advantages compared with the conventional transanal minimally invasive surgery technique. We evaluate the safety, feasibility and advantages of this technique. Methods Between February 2014 and October 2015, 9 patients underwent robotic transanal polypectomy. We performed a retrospective study in which we analyze prospectively collected data regarding patient and tumor characteristics, perioperative outcomes, pathological report, morbidity and mortality. Results A total of 5 male and 4 female patients underwent robotic TAMIS. Lesions were 6.22 cm from the anal verge. Mean size was 15.8 cm 2 . All procedures were performed in the lithotomy position. Closure of the defect was performed in all cases. Mean blood loss was 39.8 ml. Mean operative time was 71.9 min. No severe postoperative complications or readmissions occurred. Median hospital stay was 2.5 days. Conclusions Robotic TAMIS is useful to treat complex rectal lesions. Our transanal platform allowed a wider range of movements of the robotic arms and to perform all procedures in the lithotomy position.
