Summary
This study adapted laparoscopic sigmoid resection for rectal surgery in pigs, achieving successful double-stapled anastomoses. The technique proved safe and effective in a porcine model for low anterior resection.
Area of Science:
- Surgical innovation
- Minimally invasive surgery
- Gastrointestinal surgery
Background:
- A technique for laparoscopic sigmoid resection with intracorporeal anastomosis was previously described.
- Application to rectal surgery was unexplored.
Purpose of the Study:
- To evaluate the feasibility of adapting laparoscopic sigmoid resection for rectal surgery.
- To assess the safety and efficacy of this technique in a porcine model.
Main Methods:
- Ten pigs underwent low anterior resection using an articulating endoscopic stapler.
- Intracorporeal pursestring sutures and a laparoscopic pursestring clamp were employed.
- A double-stapled anastomosis was created using a circular stapler and a spike-equipped gun.
Main Results:
- Complete doughnuts were achieved in all procedures.
- All anastomoses were methylene blue tight and showed mucosal healing on histology.
- The median anastomotic level was 5.2 cm from the anal verge with an uneventful postoperative course.
Conclusions:
- The described intracorporeal technique, utilizing specialized stapling devices, is safely applicable to rectal resection.
- This approach facilitates minimally invasive rectal surgery in a porcine model.
- Further research may explore human clinical application.
