Transanal endoscopic operation for rectal lesion: a rapid initial experience.

Area of Science:

• Colorectal Surgery
• Minimally Invasive Procedures
• Gastrointestinal Endoscopy

Background:

• Transanal surgery is an established alternative for rectal lesions, offering reduced morbidity and mortality.
• The Transanal Endoscopic Operation (TEO) system is a widely recognized platform for such procedures.
• Rectal lesion treatment has evolved, with transanal approaches gaining prominence.

Purpose of the Study:

• To evaluate the safety and feasibility of the TEO system for rectal lesion resection.
• To assess the outcomes of full-thickness rectal resections performed using TEO.
• To analyze demographic, histopathological, and clinical data from patients undergoing TEO.

Main Methods:

• Retrospective analysis of a prospectively collected database of 25 patients.
• Inclusion of patients with rectal lesions suitable for transanal treatment.
• Performance of full-thickness rectum resections using the TEO system between November 2017 and July 2019.

Main Results:

• 25 rectal lesions were excised using TEO within a two-year period.
• Lesion distribution: 16 low (<4 cm), 7 mid-rectal (4-8 cm), and 2 proximal (>8 cm).
• Postoperative complications included 3 (12%) bleedings and 8 (32%) post-polipectomy syndrome.

Conclusions:

• The TEO system demonstrates safety and feasibility for rectal lesion resection.
• Full-thickness resection via TEO ensures adequate deep margins.
• Development of specialized reference centers is recommended due to the limited case numbers.
