[Colonic pouch reconstruction after low anterior rectal resection].

Area of Science:

• Colorectal surgery
• Surgical techniques
• Gastrointestinal function

Context:

• Traditional end-to-end anastomosis after low rectal resection and total mesorectal excision (TME) often leads to functional deficits.
• Low anterior resection syndrome (LARS), characterized by fecal incontinence and evacuation difficulties, affects up to 60% of patients.

Purpose:

• To evaluate alternative coloanal anastomosis techniques.
• To compare functional outcomes and anastomotic leakage rates of different surgical methods.

Summary:

• Side-to-end anastomosis, coloplasty pouch, and colonic J-pouch techniques show superior functional results compared to end-to-end anastomosis.
• These alternative methods, including pouch-anal anastomosis, offer comparable functional outcomes and anastomotic leakage rates.

Impact:

• Improved patient quality of life by enhancing continence and evacuation function.
• Provides evidence for selecting superior surgical techniques in TME to maintain bowel continuity and function.
