Summary
Transanal total mesorectal excision (TME) using transanal minimally invasive surgery (TAMIS) provides a minimally invasive solution for rectal cancer surgery, particularly in challenging cases. This approach preserves the mesorectal envelope and improves access to the distal rectum.
Area of Science:
- Surgical Oncology
- Minimally Invasive Surgery
- Colorectal Surgery
Background:
- Transanal total mesorectal excision (TME) is an emerging technique in rectal cancer surgery.
- Transanal minimally invasive surgery (TAMIS) is a key enabling technology for transanal TME.
- Challenges in rectal cancer surgery include accessing the distal rectum, especially in obese patients with narrow pelvises.
Purpose of the Study:
- To describe the evolution and historical perspective of transanal TME.
- To highlight the benefits of TAMIS-TME in rectal cancer surgery.
- To emphasize the minimally invasive advantages of the transanal approach.
Main Methods:
- Review of the historical development of transanal TME.
- Description of the application of TAMIS for TME procedures.
- Discussion of the technical aspects and patient selection for TAMIS-TME.
Main Results:
- Transanal TME, facilitated by TAMIS, allows for rectal resection and mobilization while preserving the mesorectal envelope quality.
- This approach offers a solution for difficult surgical access in the distal rectum, particularly in obese male patients with narrow pelves.
- Transanal TME is a rapidly expanding area in rectal cancer surgery.
Conclusions:
- Transanal TME represents a significant advancement in minimally invasive rectal cancer surgery.
- The historical development of this technique is crucial for understanding its current importance.
- TAMIS-TME addresses specific surgical challenges, enhancing treatment options for rectal cancer patients.

Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.
