Area of Science:

  • Colorectal Surgery
  • Minimally Invasive Surgery
  • Oncology

Background:

  • Rectal lesions, including adenomas and carcinomas, require effective treatment options.
  • Local excision is a preferred approach for certain rectal pathologies when feasible.

Purpose of the Study:

  • To evaluate the safety and efficacy of transanal endoscopic microsurgery (TEM) for local excision of rectal lesions.
  • To report outcomes in a series of patients treated with TEM for adenomas and carcinomas.

Main Methods:

  • A prospective, descriptive study involving 42 patients with rectal lesions.
  • Procedures included mucosectomy (6 cases) and full-thickness excision (36 cases) via TEM.
  • Mean patient age was 65 years, with a follow-up period averaging 11 months.

Main Results:

  • The study analyzed outcomes including operating time, blood loss, tumor characteristics, and postoperative stay.
  • Morbidity included one case of hemorrhage and one of perforation; no mortality was observed.
  • Follow-up revealed temporary flatus incontinence in 6 cases, one carcinoma recurrence, and three adenoma recurrences/new adenomas.

Conclusions:

  • Transanal endoscopic microsurgery (TEM) is a safe and effective technique for treating rectal lesions.
  • Low morbidity, acceptable recurrence rates, and short hospital stays support TEM as a procedure of choice for indicated local rectal surgery.
