Expanding the boundaries of minimally invasive surgery: the feasibility of robotic natural orifice transluminal extraction colectomy and robotic no-incision colectomy in colorectal practice

摘要

PURPOSE: Minimally invasive surgery offers reduced trauma, accelerated recovery, and shorter hospital stays. Robotic technology further enhances laparoscopic precision, particularly in colorectal procedures. This study investigated the safety and effectiveness of robotic natural orifice transluminal extraction colectomy (R-NOTEC) and robotic no-incision colectomy (R-NIC), comparing these techniques to the conventional robotic colectomy. METHODS: Outcomes of patients undergoing robotic-assisted colorectal resection-either conventional robotic colectomy or R-NOTEC/R-NIC-using a single docking technique at a tertiary hospital over 3 years were analyzed. All patients were managed according to established Enhanced Recovery After Surgery protocols. RESULTS: In total, 100 patients were included, with 25 receiving R-NOTEC or R-NIC. The median age was 65 years (range, 30-82 years), and the median body mass index was 31.0 kg/m2 (range, 20.1-43.0 kg/m2). The median length of stay was significantly shorter in the R-NOTEC/R-NIC group than in the conventional robotic group (2.0 days vs. 3.4 days, P=0.021). Other outcomes, such as circumferential resection margin status, lymph node yield, and mortality, were similar between groups. The R-NOTEC/R-NIC group exhibited a slightly lower complication rate, as well as less opioid use. No conversions to open surgery occurred in either group. CONCLUSIONS: R-NOTEC/R-NIC offer significant promise in colorectal surgery by minimizing trauma, expediting recovery, and maintaining oncologic safety. Nevertheless, these procedures require specialized surgical expertise and careful patient selection. Further research should focus on long-term outcomes and standardization of these techniques. .
