Robotic-assisted colorectal surgery – initial results

Abstract

Introduction: The mini invasive procedure in colorectal surgery is gaining ground as an alternative to conventional surgery. Colorectal surgery has significantly evolved since the advent of the automatic stapler devices and subsequently with the minimally invasive approach. The next logical step - the robotic assisted surgery was developed to satisfy surgeons’ needs to the area of colorectal surgery and to offer a new and safer method to patients. The evidence for benefits of its use in this area appears to be promising. Aim: The aim of this study was to analyse and share our initial results in robotic colorectal surgery and compare them with literature data. Materials and methods: A retrospective study was conducted in order to review seven patients with colorectal cancers operated by the robotic-assisted technique over three months in the initial phase of the learning curve. Gender, age, diagnosis, and surgical indication, type of surgery performed, surgical time, conversion, bleeding, post-operative complications, and hospital stay, were analysed and described. A literature review was performed on the role of robotic surgery in colorectal cancer. Results: Seven patients were operated, 5 males and 2 females with a mean age of 68.2 years. The following procedures were performed: left hemicolectomy with primary anastomosis, low anterior resection, left hemicolectomy, sigmoid resection. The mean surgery time for the seven patients was 4 h 06 min, with a time on the console of 2 h and 50 min, and mean bleeding of 192 cc. None of the patients required conversion and the hospital stay was 7 days. Conclusions: Despite the reduced case series, the initial results of our learning curve in colorectal robotic surgery are among the parameters imposed by the medical literature.
