Same-Day Repair of Recto-Vaginal Fistula Using the Robotic Trans-Anal Minimally Invasive Technique How We Do It

Abstract

Background: Traditional open surgical repairs, including flap techniques, are associated with high recurrence rates and significant morbidity. Robotic-assisted techniques have emerged as promising alternatives to conventional methods due to improved visualization, precision, and reduced postoperative complications. The robotic transanal minimally invasive surgery (R-TAMIS) technique offers a new route for rectovaginal fistula (RVF) repair, providing enhanced dexterity and access through the transanal approach. Methods: An R-TAMIS technique was employed for same-day repair of RVF using the da Vinci Xi® system. After bowel preparation and prophylactic antibiotics, the patient was positioned in prone Jackknife. The GelPOINT Path was used for transanal access, and robotic ports were placed. The fistula tract was identified and dissected circumferentially. The vaginal wall was closed with absorbable barbed sutures, reinforced with fibrin sealant and acellular dermal mesh. The rectal wall was then closed, and patency was confirmed via endoscopic inspection. Results: The procedure was well tolerated, and the patient was discharged the next day. Minimal postoperative pain was reported but didn’t require analgesics. No major complications were observed in the immediate postoperative period. The robotic approach provided enhanced visualization and dexterity, facilitating precise dissection and suturing. The technique has already been successfully applied to benign RVFs and select rectourethral fistulas. Conclusion: Robotic-assisted transanal repair using the R-TAMIS technique is a feasible and effective minimally invasive option for selected patients with benign RVFs. With proper patient selection and dedicated surgical technique, this approach may reduce morbidity and improve outcomes compared to traditional open or laparoscopic methods.
