New laparoscopic double-stapling technique.

Area of Science:

• Surgical Innovation
• Minimally Invasive Surgery
• Colorectal Surgery

Background:

• Laparoscopic surgery for colon cancer is established, but laparoscopic rectal surgery lacks randomized trial evaluation.
• Key challenges in laparoscopic rectal surgery include bowel clamping, irrigation, and rectal transection.
• Current laparoscopic rectal surgery is less reliable than open rectal surgery.

Purpose of the Study:

• To introduce and evaluate a novel technique for laparoscopic rectal surgery.
• To overcome the technical difficulties associated with laparoscopic rectal procedures.
• To enhance the reliability and quality of laparoscopic rectal cancer surgery.

Main Methods:

• The laparoscopic double-stapling technique was developed to address clamping, irrigation, and transection issues.
• Curved Doyen forceps are used for rectal wall clamping.
• An endolinear stapler is employed for rectal transection under pneumoperitoneum.
• The technique was applied in eight cases of rectal surgery.

Main Results:

• The laparoscopic double-stapling technique ensured secure bowel clamping and rectal irrigation.
• An average of 1.6 stapler cartridges were used per patient (maximum 2).
• No major complications were observed in the cases utilizing this technique.

Conclusions:

• The laparoscopic double-stapling technique is effective for laparoscopic rectal surgery.
• This technique improves the quality of rectal surgery.
• It expands the applicability of laparoscopic surgery for rectal cancer cases suitable for low anterior resection.
