Summary
Transanal endoscopic microsurgery (TEMS) effectively removed rectal tumors in 100 patients. This minimally invasive technique showed high success rates for adenomas and selected rectal cancers.
Area of Science:
- Colorectal Surgery
- Minimally Invasive Procedures
- Oncology
Background:
- Rectal tumors, including adenomas and adenocarcinomas, require effective and minimally invasive treatment options.
- Transanal endoscopic microsurgery (TEMS) has emerged as a technique for localized rectal lesions.
Purpose of the Study:
- To evaluate the efficacy and outcomes of transanal endoscopic microsurgery (TEMS) for rectal tumors in a UK multi-center study.
- To assess the complete excision rates and recurrence patterns for benign adenomas and invasive adenocarcinomas treated with TEMS.
Main Methods:
- A retrospective analysis of 100 transanal endoscopic microsurgical excisions performed over 28 months in three UK centers.
- Histological examination to confirm tumor type (benign adenoma vs. invasive adenocarcinoma) and assess completeness of excision.
Main Results:
- Complete tumor excision was achieved in 91% of adenomas and 96% of adenocarcinomas.
- Of 23 invasive adenocarcinomas, 18 were preoperatively diagnosed; 2 patients experienced local recurrence after treatment.
- Four patients with villous adenomas had recurrences.
Conclusions:
- Transanal endoscopic microsurgery demonstrates a high success rate for complete excision of rectal adenomas and selected rectal adenocarcinomas.
- TEMS is a valuable technique for managing sessile adenomas in the mid and upper rectum, as well as carefully selected early-stage rectal cancers.
- Initial UK results for TEMS align with international findings, supporting its role in rectal tumor management.
