Background: Natural orifice transluminal endoscopic surgery (NOTES), a new frontier of minimally invasive surgery, uses the body's natural orifices to create an access for surgical procedures. This study aimed to verify the technical feasibility of ileorectal bypass performed entirely through a transanal access.
Methods: The procedure was performed on 10 domestic pigs, after which they were killed. A transanal endoscopic microsurgery (TEM) device and endoscopic and laparoscopic instruments were used.
Results: The findings demonstrated that an ileorectal bypass through a transanal access is feasible. The principal steps of a standardized transanal procedure are as follows: confirm a rectal perforation above the peritoneal reflection, perform peritoneoscopy using a standard gastroscope, grasp the small bowel with retrieval forceps and pull it through the rectal hole, suture the ileum and the rectum together using a TEM device, open the ileal loop, and perform endoscopic exploration. Satisfactory anastomosis and no signs of procedure-related complications were confirmed by a post procedure laparotomy.
Conclusions: Ileorectal bypass through a transanal access is technically feasible in a porcine model, and although still at an experimental stage, it could become a surgical option for treating some types of colonic strictures.

Background: Surgical training in virtual, animal and cadaver models is essential for minimally invasive surgery. Thiel cadavers are suitable for laparoscopy, but there are few data about the use of embalmed (Tutsch method) and slightly embalmed (Thiel method) cadavers in procedures of Natural Orifice Transluminal Endoscopic Surgery (NOTES), which are usually developed and learned on swine models and fresh frozen cadavers. The aim of this study was thus to assess the use of these cadavers for NOTES approaches.

Aim: Intra-abdominal desmoid disease is one of the most common extra-intestinal manifestations of familial adenomatous polyposis. Small bowel obstruction occurs frequently in affected patients and is notoriously difficult to treat. The aim of this study was to review the management and outcome of desmoid-related small bowel obstruction.

Aim: Enterocutaneous fistula is a severe complication of intra-abdominal desmoid disease. It is hard to repair because of the presence of the desmoid itself, the possibility of distal obstruction and the complexity of multiple laparotomies. Here we report the outcome of a series of patients presenting with abdominal desmoid disease and associated enterocutaneous fistula.
