Modified single stapler technique in anterior resection for rectal cancer

Area of Science:

• Colorectal Surgery
• Surgical Oncology
• Gastrointestinal Surgery

Background:

• Technical difficulties during colorectal surgery are associated with increased complication rates.
• The double stapler technique (DST) is standard but can be challenging in specific patient anatomies.
• Alternative methods are needed to ensure safe anastomosis in complex cases.

Purpose of the Study:

• To introduce and evaluate a modified single stapler technique (MSST) as a solution for technical difficulties encountered during colorectal surgery.
• To assess the safety and efficacy of the MSST, particularly in patients with narrow pelvis and distal tumors.
• To determine the rate of anastomotic leak with the MSST.

Main Methods:

• The MSST involves dividing the colon proximally to the tumor, performing a tumor-specific mesorectal excision, and placing two distal purse-string sutures.
• A circular stapler is introduced transanally, with sutures secured around the stapler shaft and colonic lumen.
• Resection occurs between sutures, followed by anvil connection and stapler firing.

Main Results:

• The modified single stapler technique was successfully implemented in patients facing technical challenges with the double stapler technique.
• A key finding was the absence of anastomotic leaks in all patients who underwent this modified procedure.
• The technique proved particularly useful in cases involving narrow pelves and distal rectal tumors.

Conclusions:

• The modified single stapler technique is a safe and effective alternative for colorectal surgery when technical difficulties arise.
• This method offers a viable solution for achieving a secure anastomosis in patients with challenging pelvic anatomy and distal tumors.
• The MSST demonstrates potential to reduce complications associated with standard techniques in specific surgical scenarios.
