Abstract

As robotic surgery continues to disseminate into the field of colon and rectal surgery, there is a growing interest in the utilization of intracorporeal anastomosis to potentially improve surgical outcomes. The purpoe of this study was to compare feasibility, safety, and short-term outcomes of robotic sigmoid and low anterior resections performed with completely intracorporeal anastomosis (CICA) technique to the traditional extracorporeal assisted anastomosis (ECAA) technique. Consecutive series of patients who underwent elective robotic sigmoid or low anterior resections for benign or malignant disease utilizes either CICA or ECAA between August 2017 and November 2019. Surgical complications were assessed until 30 postoperative days and compared between the two groups. A total of 160 patients were identified; 73 (45.6%) in the CICA group and 87 (54.4%) in the ECAA group. Most of the procedures were performed for malignancy (76%). Estimated blood loss was lower in the CICA group (80.7 mL vs. 110.2 mL; p = 0.048), while operative times were longer (5.9 ± SD hours vs. 4.9 ± SD hours; p = < 0.001). Overall conversion rate was 1.9%, with no conversions in the CICA group. Overall complications occurred in 54 patients (33.8%) with 13 (8.3%) representing major complications. There were no significant differences in 30 day outcomes between the two groups. This study demonstrates the feasibility and safety of robotic sigmoid and low anterior resections with CICA. Outcomes for robotic sigmoid and low anterior resections are encouraging regardless of anastomotic technique (CICA vs ECAA).
