Clinical Report: Integrating Single-Port Robotic Technology into Colorectal Surgery

Overview

This SAGES task-force review examines the FDA-approved single-port (SP) robotic platform, its technical features, and implementation considerations for colorectal procedures. The source describes applications in transanal minimally invasive surgery, right colectomy, and low anterior resection/total mesorectal excision, while noting that comparative evidence on wound morbidity remains limited.

Background

Progression from open surgery to laparoscopic and multiport robotic techniques has been associated with reduced postoperative pain, shorter hospitalization, and shorter recovery while preserving oncologic outcomes, according to the source. Multiport approaches nevertheless require multiple incisions, with potential port-site complications, herniation, and cosmetic concerns. Single-incision laparoscopic surgery sought to reduce access trauma but was constrained by loss of triangulation, instrument crowding, and surgeon fatigue. The SP platform is designed to address these technical limitations through articulating instruments, a flexible three-dimensional camera, and multi-quadrant access through one incision.

Data Highlights

Key Findings

• The review describes one FDA-approved SP robotic platform combining single-incision access with robotic dexterity while preserving triangulation through a single 25 mm port.
• The platform incorporates three fully articulating instruments and a flexible 3-D camera in a multichannel cannula; the source states that this design addresses instrument collisions and surgeon stance and ergonomics associated with earlier single-incision approaches.
• SP access uses 360-degree boom rotation for multi-quadrant access, while articulating instruments are intended to preserve triangulation through one incision.
• For transanal surgery, the review describes flexible wristed instruments and an articulating “cobra” camera that provides stable views of rectal walls without repeated repositioning; a third robotic arm supports retraction, full-thickness excision, and suture closure.
• The task force evaluated platform features, instrumentation, workflow, patient selection, and operative techniques across TAMIS, right colectomy, and LAR/TME, drawing on published literature and collective subject-matter expert experience.
• The source states that SP approaches may lessen cumulative abdominal wall trauma, but definitive comparative evidence on wound morbidity remains limited.

Clinical Implications

The review provides technical and workflow considerations for colorectal surgeons and institutions evaluating SP implementation, including incision placement, docking, exposure, dissection, vascular control, anastomosis, and defect closure. It also identifies limited comparative evidence on wound morbidity, so the source does not establish a definitive wound-outcome advantage over other approaches.

Conclusion

The SAGES task-force review characterizes SP robotics as an evolving platform for several colorectal applications, with design features intended to address limitations of earlier single-incision techniques. Its discussion combines published evidence and expert experience while acknowledging that comparative evidence for wound morbidity remains limited.
