Single-access laparoscopic rectal surgery is technically feasible

Area of Science:

• Surgical Oncology
• Minimally Invasive Surgery

Background:

• Single-access laparoscopic surgery (SALS) is established for colectomies.
• Mid to low rectal procedures like total mesorectal excision (TME) present technical challenges for SALS.

Purpose of the Study:

• To evaluate the short-term outcomes of a novel single-access technique for laparoscopic rectal cancer surgery.
• To assess pathologic results and immediate complications associated with this approach.

Main Methods:

• Prospective study involving patients with middle rectum to anal canal cancer undergoing single-access laparoscopic rectal resection.
• Standard total mesorectal excision performed via a single umbilical multichannel port.
• Identification of critical vascular structures (inferior mesenteric artery and vein) through a mesocolic window.

Main Results:

• No perioperative complications were reported.
• Mean operative time: 269 minutes; Median hospital stay: 7 days.
• Mean wound size: 5.5 cm; Median harvested lymph nodes: 15; Intact mesorectal capsules in all patients.

Conclusions:

• Single-access laparoscopic surgery for rectal cancer is a feasible approach.
• The technique upholds oncologic principles and ensures patient safety.
• This method offers a viable alternative for specific rectal cancer resections.
