Robotic proctectomy with ileal pouch-anal anastomosis (IPAA) shows reduced blood loss and fewer conversions compared to laparoscopic approaches. While operating times are longer, short-term outcomes are comparable, warranting further investigation into long-term benefits.
Area of Science:
- Surgical Oncology
- Minimally Invasive Surgery
- Gastrointestinal Surgery
Background:
- Ileal pouch-anal anastomosis (IPAA) is the gold standard for ulcerative colitis, familial adenomatous polyposis, and Crohn's colitis.
- Robotic surgery offers potential advantages in postoperative outcomes and reduced hospital stay.
- Limited comparative studies exist on robotic versus laparoscopic IPAA.
Purpose of the Study:
- To compare short-term (30-day) postoperative outcomes of robotic versus laparoscopic proctectomy with IPAA and diverting loop ileostomy.
- To evaluate differences in complications, length of stay, blood loss, and readmission rates.
Main Methods:
- Retrospective observational study at a single, high-volume tertiary referral center.
- Included 217 adult patients undergoing minimally invasive proctectomy with IPAA and diverting loop ileostomy (2015-2023).
- Compared 30-day complications, length of stay, estimated blood loss, conversion rates, readmissions, and reoperations.
Main Results:
- Robotic IPAA had significantly longer operating times (263 vs. 228 minutes) but lower estimated blood loss (81.5 vs. 126.8 mL) and fewer conversions (0% vs. 8.2%).
- No significant differences were observed in length of stay, 30-day morbidity, readmission, or reoperation rates between groups.
- Robotic patients received more intraoperative fluids (3099 vs. 2472 mL).
Conclusions:
- Robotic proctectomy with IPAA may offer benefits in reduced blood loss and conversion rates while maintaining comparable short-term outcomes to laparoscopy.
- Limitations include retrospective design, single-center data, and lack of long-term and quality-of-life data.
- Further research is needed to assess long-term efficacy and patient-reported outcomes.
