Purpose/Background: Minimally invasive approaches to total abdominal colectomy (TAC) have been shown to be safe and effective, offering benefits such as reduced hospital stay, blood loss, and mortality. Despite the growing body of literature on robotic surgery, few studies have specifically evaluated the robotic approach for TAC. The objective of this study was to review and compare the experiences of a group of colorectal surgeons with laparoscopic and robotic TAC, and to determine whether significant differences in outcomes exist.

Methods/Interventions: A retrospective chart review was conducted of 29 patients who underwent laparoscopic (n = 16), and robotic (n = 13) elective TAC performed by four colorectal surgeons between March 2018 and September 2025. Demographic, perioperative and surgical data, as well as short-term complications, were analyzed. Laparoscopic and robotic procedures (da Vinci® Xi) were selected based on surgeon preference and platform availability.

Results/Outcomes: See Tables 1 and 2. A significant age difference was observed, with robotic patients being older by a mean of 11 years (p = 0.04). Body mass index (BMI), American Society of Anesthesiologists (ASA) score, and Charlson Comorbidity Index were comparable between groups. The most common indication for laparoscopic TAC was adenomatous polyposis (8), followed by ulcerative colitis (5), whereas in the robotic group, colorectal cancer with adenomatous polyposis (7) and adenomatous polyposis (3) were most frequent. Robotic cases tended to have higher estimated blood loss (100 mL), longer operative times (323 min), and longer length of stay (10 days), although these differences were not statistically significant. An ileorectal circular stapled anastomosis was used in the laparoscopic group, whereas an intracorporeal ileorectal side-to-side anastomosis was adopted in the robotic group and performed on 7 patients. Two patients in the robotic group required conversion to open surgery, and four required reoperations. One patient in the laparoscopic group developed an anastomotic leak. No laparoscopic cases were converted, and two required reoperation. No 30-day mortality was reported.

Conclusion/Discussion: Robotic and laparoscopic TAC are safe minimally invasive approaches with similar short-term outcomes and low morbidity in elective cases. Operative time, blood loss, and length of stay were comparable to published data. The transition to an intracorporeal side to side ileorectal anastomosis in the robotic cohort was facilitated by the platform's capabilities. Study limitations include the small sample size and retrospective design.Total abdominal colectomy: Patients' demographics
