EEA stapler in low anterior anastomosis

Area of Science:

• Colorectal Surgery
• Surgical Oncology
• Gastroenterology

Background:

• Preserving the anal sphincter is a primary goal in treating colorectal malignancies.
• Traditional transsacral and low anterior resections with end-to-end anastomosis can lead to significant morbidity and leakage.
• The EEA stapler presents a viable alternative for restoring bowel continuity.

Purpose of the Study:

• To evaluate the safety and efficacy of the EEA stapler in patients undergoing rectal cancer surgery.
• To assess complication rates, including anastomotic leakage and functional outcomes, associated with EEA stapler use.
• To determine if the EEA stapler facilitates sphincter preservation and reduces the need for protective colostomies.

Main Methods:

• A retrospective study of 58 patients with adenocarcinoma of the rectum treated over three years.
• All patients underwent procedures using an EEA stapler introduced transanally.
• Curative (49) and palliative (9) procedures were analyzed.

Main Results:

• No clinically significant anastomotic leakage was observed in any patient.
• No protective colostomies were required.
• Minor bleeding occurred, but no transfusions were needed; temporary soiling affected 16 patients, with no frank incontinence reported.

Conclusions:

• The EEA stapler is a safe, reliable, and simple instrument for rectal cancer surgery.
• It effectively re-establishes bowel continuity, potentially reducing morbidity and the need for colostomies.
• Further long-term follow-up is essential to assess recurrence rates and establish definitive criteria for its use.
