Summary
This study shows the single-port robotic system with an access port is a safe and effective tool for transanal minimally invasive surgery, allowing access to the entire rectum and beyond. It offers a flexible alternative to traditional methods for rectal surgery.
Area of Science:
- Minimally Invasive Surgery
- Surgical Robotics
- Gastrointestinal Surgery
Background:
- Traditional transanal access platforms and single-port systems have limitations for distal rectal access.
- The da Vinci single-port system offers potential for improved flexibility in transanal minimally invasive surgery.
Purpose of the Study:
- To evaluate the safety and efficacy of the single-port access port for transanal minimally invasive surgery.
- To assess the feasibility of accessing the anal canal, rectum, and distal sigmoid colon using this system.
Main Methods:
- A case series of 17 patients undergoing transanal minimally invasive surgery with the da Vinci single-port system and access port.
- Primary outcomes included procedural success, intraoperative and postoperative complications.
- Tumor location, pathology, and margin status were also analyzed.
Main Results:
- All 17 procedures were technically successful without conversion to alternative methods.
- No intraoperative complications were reported.
- The access port enabled lesion access up to 22 cm from the anal verge.
Conclusions:
- Robotic transanal minimally invasive surgery using the single-port system with the access port is safe and feasible.
- This approach allows for the treatment of a wide range of lesions via full and partial-thickness resections.
- Further research may indicate improved patient comfort due to the soft, flexible access system.
