Summary
Transanal endoscopic microsurgery (TEMS) offers a tissue-saving approach for removing rectal adenomas and early rectal cancers. This minimally invasive technique provides better access and lower recurrence rates compared to conventional methods.
Area of Science:
- Gastroenterology
- Surgical Oncology
- Colorectal Surgery
Background:
- Sessile adenomas and early rectal carcinomas often require surgical intervention.
- Conventional transanal techniques have limitations in reach and high recurrence rates.
- Minimally invasive approaches are needed for better patient outcomes.
Purpose of the Study:
- To evaluate the efficacy and safety of transanal endoscopic microsurgery (TEMS) for rectal adenomas and early carcinomas.
- To compare TEMS with conventional surgical methods.
- To highlight TEMS as an economical and tissue-saving surgical option.
Main Methods:
- TEMS combines endoscopic visualization with conventional surgical techniques.
- Adenomas are removed via mucosectomy or full-thickness excision.
- Carcinomas undergo full-thickness excision with adequate margins and lymph node dissection when necessary.
Main Results:
- TEMS allows for precise excision of rectal lesions.
- The technique enables removal of tumors in the sacral cavity.
- It is described as the most economical and tissue-saving surgical option.
Conclusions:
- Transanal endoscopic microsurgery is a highly effective technique for rectal adenomas and early rectal cancers.
- TEMS offers advantages over conventional transanal surgery, including reduced recurrence.
- This minimally invasive approach represents a significant advancement in colorectal surgery.
