Summary
A novel single-port transanal endoscopic approach offers a safe and effective alternative for treating rectal adenomas and early rectal cancer. This minimally invasive technique demonstrates promising results with good outcomes and faster recovery compared to traditional methods.
Area of Science:
- Colorectal Surgery
- Minimally Invasive Procedures
- Oncology
Context:
- Radical surgery for rectal cancer leads to significant morbidity and functional changes.
- Conventional transanal surgery has a high recurrence rate.
- Transanal endoscopic microsurgery (TEM) is the current standard for large rectal adenomas and early-stage rectal cancer.
Purpose:
- To evaluate the efficacy and safety of a new single-port transanal endoscopic approach.
- To assess the feasibility of this technique for rectal adenomas and early rectal cancer.
Summary:
- Five patients (four with villous adenoma, one with in situ carcinoma) underwent the single-port transanal endoscopic procedure.
- Lesions were located in the mid-rectum (mean 9 cm from anal margin), posterior side.
- All resections had negative margins, with mean adenoma size of 4 cm and carcinoma size of 3 cm. Mean surgical time was 55 minutes, with 48-hour discharge.
Impact:
- The single-port transanal endoscopic approach is a simple, reproducible, and cost-effective alternative to TEM.
- This technique offers a less invasive option for managing selected rectal lesions.
- Positive outcomes suggest potential for wider adoption in early rectal lesion treatment.
