Abstract
Objective
Despite being reported safety, the advantages of transanal minimally invasive proctocolectomy (TAMIP) are controversial, and comparative studies on postoperative defecation function between ileal pouch-anal anastomosis (IPAA) using laparoscopic transanal manipulation (TAMIP-IPAA) and without this technique (traditional IPAA) are lacking. This study analyzed TAMIP's impact on short-term and postoperative defecation function in patients with ulcerative colitis (UC) to evaluate its safety and feasibility.
Methods
Inclusion criteria comprised patients with UC undergoing minimally invasive proctocolectomy at our hospital from May 2014 to May 2023. The TAMIP-IPAA approach involved precise rectal mucosa removal while preserving the sphincter muscle during laparoscopic transanal manipulation.
Results
In the evaluation of short-term outcomes for 71 patients undergoing proctocolectomy, the TAMIP group (37 patients) outperformed the non-TAMIP group in operative time (395 vs. 289 min, p < 0.001) and postoperative hospital stay (12 vs. 8 days, p < 0.001). Additionally, TAMIP-IPAA demonstrated advantages over traditional IPAA (seven patients), in operative time (443 vs. 289 min, p = 0.006), intraoperative blood loss (392 vs. 130 mL, p = 0.001), postoperative hospital stay (18 vs. 8 days, p = 0.003), anastomotic leakage (42.9% vs. 8.1%, p = 0.041), and re-admission within 30 days (57.1% vs. 8.1%, p = 0.009). Wexner scores were significantly superior in the TAMIP-IPAA group at 6 months (14.5 vs. 8.0 points, p = 0.029) and 1 year post stoma closure (14.0 vs. 7.0 points, p = 0.020), indicating enhanced short-term outcomes and defecation function compared to traditional IPAA.
Conclusions
TAMIP-IPAA for UC has the potential to offer promising benefits, including the enhancement of short-term outcomes and the improvement of defecation function.
