Abstract
With the previous experiences in performing laparoscopic for over a period of 15 years and da Vinci colorectal surgeries from 2010 to 2013, we started operating using the Cambridge Medical Robotics (CMR) Versius Surgical Robot System. The aim of the study is a prospective analysis and evaluation of short-term results of consecutive patients to study the technical feasibility and oncological outcome of robot-assisted low anterior resection (LAR) and ultralow anterior resection (ULAR), using the CMR Versius Surgical Robot System. This study was conducted at single minimal access surgery institute. 31 patients with colorectal adenocarcinoma underwent robot-assisted LAR and ULAR between August 2019 and March 2020. Patient characteristics, perioperative parameters and complications were evaluated. Surgical and pathological outcomes such as quality of Total Mesorectal Excision (TME), free circumferential resection margins and number of lymph nodes dissected were also evaluated. Of 31 patients, 23 were men and 8 women, with mean age of 55.6 years. The mean robotic operative time was 51 min and the mean blood loss was 55 ml. The mean robot docking and undocking time was 17 min and 5 min, respectively. The mean hospital stay was 7 days. The longitudinal and circumferential resection margins were negative in all patients. Histopathological reports of 27 among 31 patients showed complete TME. Splenic flexure of colon mobilization was done laparoscopically. We feel that Versius robot has the qualities in terms of dexterity, vision and intuitive movements, and to translate this technical ability into oncological safety.
