Transanal endoscopic proctectomy: a case in swine
Hepato-Gastroenterology
|June 6, 2014
Summary
Transanal endoscopic proctectomy is a feasible natural orifice translumenal endoscopic surgery approach for rectosigmoid resection. This minimally invasive technique may offer an alternative for complex laparoscopic total mesorectal excision in rectal cancer surgery.
Area of Science:
- Surgical Oncology
- Minimally Invasive Surgery
- Gastroenterology
Background:
- Laparoscopic total mesorectal excision (TME) is standard for rectal cancer but faces technical challenges and high conversion rates.
- Minimally invasive rectal surgery platforms offer novel approaches for extraperitoneal rectal procedures.
Purpose of the Study:
- To evaluate the feasibility of transanal endoscopic proctectomy (TEP) for natural orifice translumenal endoscopic surgery (NOTES) rectosigmoid resection in a swine model.
- To assess TEP as a potential alternative to challenging laparoscopic TME procedures.
Main Methods:
- A feasibility, non-survival study was conducted in a swine model.
- Full-thickness circumferential rectal dissection and proximal extension were performed.
- Specimen exteriorization, transection, and proximal colon anastomosis to the distal rectum were completed.
Main Results:
- The transanal endoscopic proctectomy procedure took 3 hours and 10 minutes.
- A 12 cm specimen was retrieved, intact with respect to the rectal wall and mesorectum.
- No injuries to adjacent organs were observed during the procedure.
Conclusions:
- Transanal endoscopic proctectomy is a feasible surgical technique for rectosigmoid resection in a swine model.
- TEP may represent a viable alternative for rectal cancer surgery, particularly in cases where laparoscopic TME is technically difficult.
