Transanal endoscopic microsurgery for rectal adenomas: single center experience

Area of Science:

• Colorectal Surgery
• Minimally Invasive Procedures
• Oncology

Background:

• Transanal endoscopic microsurgery (TEM) is a primary treatment for rectal adenomas.
• Concerns exist regarding anorectal function after TEM procedures.

Purpose of the Study:

• To evaluate the safety and efficacy of TEM for rectal adenoma removal.
• To assess morbidity, recurrence rates, and functional outcomes post-TEM.

Main Methods:

• Retrospective review of 72 patients undergoing TEM for rectal adenomas (2009-2014).
• Analysis focused on 41 patients with complete follow-up data.
• Data collected included demographics, operative details, pathology, complications, and functional outcomes (FISI, Wexner scores).

Main Results:

• No intraoperative complications were reported.
• Postoperative complications occurred in 9.8% of cases (urinary retention, hemorrhage), managed conservatively.
• A single recurrence (2.4%) was observed.
• Mean FISI score was 7.6 ±9.2; mean Wexner score was 2.3 ±3.4, indicating good functional results.

Conclusions:

• TEM demonstrates a low rate of complications and recurrence in treating rectal adenomas.
• The procedure is associated with favorable anorectal functional outcomes.
• TEM is confirmed as an effective and safe therapeutic option for rectal adenomas.
