[Aspects of low anterior rectum resection]

Area of Science:

• Oncology
• Surgical Gastroenterology
• Medical Technology

Context:

• Analysis of 162 low anterior resections for upper and medial rectal ampulla adenocarcinoma (1999-2006).
• Evaluation of surgical techniques for rectal cancer treatment.
• Focus on minimizing local recurrence and improving functional outcomes.

Purpose:

• To present results analysis of low anterior resections for rectal adenocarcinoma.
• To introduce and evaluate a novel method for marking the distal resection border using optical coherent tomography.
• To compare outcomes of total versus partial mesorectal excision.

Summary:

• A new method using optical coherent tomography for marking the distal resection border was developed.
• Mesorecectomy demonstrated a lower local recurrence rate (7.89%) compared to anterior resection with mesorectum preservation (14.28%).
• Indications for colon mobilization, ostomy types, and strategies for preventing anal incontinence were established.

Impact:

• Provides evidence supporting the efficacy of mesorecectomy in reducing rectal cancer recurrence.
• Introduces an innovative technique for enhancing surgical precision in rectal resections.
• Offers guidelines for managing complications and improving quality of life post-rectal surgery.
