Background and objectives: The application of pure natural orifice translumenal endoscopic surgery (NOTES) to intra-abdominal visceral resections remains limited due to the complexity of the dissection. This study aimed to assess the safety and feasibility of laparoscopic right colectomy using a purely transvaginal approach.
Methods: The data of 12 continuous patients with colon neoplasia who underwent transvaginal right colectomy from November 2018 to July 2020 were prospectively collected, and their perioperative events were recorded.
Results: The patients' median age was 70.4 years. Four were diagnosed with colon adenoma and eight with adenocarcinoma. The median operative time was 185 min, with a median blood loss of 25 ml. The median time to gas passing was 32.5 h after surgery. The median postoperative hospital stay was 6 days. One operation was converted to hybrid NOTES due to difficulty with the anastomosis, and one was converted to laparoscopic surgery because of vascular injury. Three cases were grades I, II, and III according to the Clavien-Dindo classification.
Conclusion: Pure NOTES right colectomy using the transvaginal approach is feasible and safe with good short-term outcomes. We recommend this novel technique for highly-selected patients with no more than a D2 dissection performed by experienced colorectal surgeons.
