Robotic pursestring technique in low anterior resection

Area of Science:

• Minimally Invasive Surgery
• Surgical Oncology
• Robotic Surgery

Background:

• Laparoscopic low anterior resection presents challenges in rectal division and anastomosis due to instrument limitations in the pelvic region.
• Robotic technology offers enhanced dexterity to overcome these limitations.

Purpose of the Study:

• To describe a technique for controlled rectal transection and robotic purse-string placement using the da Vinci Robotic system.
• To evaluate the safety and feasibility of this robotic approach in low anterior resection.

Main Methods:

• A robot-assisted low anterior resection was performed on three patients with rectal cancer.
• The procedure involved controlled rectal transection and purse-string suture placement.
• Safety, feasibility, and immediate postoperative outcomes were assessed.

Main Results:

• The technique was successfully completed in all three patients without intraoperative complications.
• One patient experienced temporary bilateral femoral neuropathy.
• Mean operative time was 339.6 minutes, with all patients discharged by postoperative day five.

Conclusions:

• The da Vinci Robot facilitates controlled rectal transection and secure purse-string placement for low anterior resection.
• This technique enables a right-angled rectal division and a secure, single-stapled anastomosis.
• Initial results suggest feasibility and safety, but larger studies are needed.
