Abstract

The Natural Orifice Transluminal Endoscopic Surgery (NOTES) is an abdominal operation carried out with flexible endoscopic instruments and their advanced versions via natural orifices. The NOTES causes theoretically less pain, operative stress, shorter hospitalization, quicker recovery and it is scarless. The aim of this investigation was to evaluate the feasibility and safety of transgastric small bowel resection. Materials and methods: Seven domestic pigs were investigated and entered the study; body weight 25 kg in average. General anesthesia was performed. One trocar was used for laparoscopic observations during gastrotomy and transgastric penetration with the gastroscope, later for assistance with a grasper for manipulation of the bowel loops and for the application of the linear stapling device. Then the needle knife was used to complete a 1.5 cm long incision in the gastric wall. The gastroscope was advanced into the peritoneal cavity and a small bowel loop was identified and elevated with a flexible grasper. Through the second channel of the scope a coag grasper was used to dissect the mesentery. Then a linear stapler was inserted through the assisting trocar and the resection was performed. Afterwards the bowel ends were opened with the needle knife and the stapler was reinserted for a side-to-side anastomosis. The specimen was removed via the stomach. Gastric closure was completed by laparoscopic mini-instruments through the stapler-port. All special events and all problems were prospectively documented. Follow-up was performed over 2 weeks and body weight was recorded. Then a laparoscopy was performed to document adhesions or abscess formation. Finally the animals were sacrificed to evaluate further evidence of infection or adhesions. Results: The operations were carried without complications, there was no case of letal outcome. On the 12th day the abdominal laparoscopic revision was carried out, after the revision in one case adhesion could be detected, no other kinds of complications were noticed. Conclusion: According to our results, the transgastric small bowel resection is a safe procedure, but further special instruments are needed. These experimental procedures should be evaluated carefully and critically in clinical practice.
