摘要
Background: Transluminal access site closure remains a major challenge in natural orifice transluminal endoscopic Surgery (NOTES). Objective: Our purpose Was to develop in vivo leak tests for evaluation of the integrity of transgastric access closure. Settings: Survival experiments on 12 50-kg pigs. Design and Interventions: After a standardized transgastric approach to the peritoneal cavity and peritoneoscopy the gastric wall incision was closed with T-bars (Wilson-Cook Medical, Winston-Salem, NC) deployed on both sides of the incision and then cinched together. Gastrotomy closure was assessed with air and fluid leak tests. The animals were observed for 1 week and then underwent endoscopic evaluation and necropsy. Main Outcome Measurements: (1) Leak-proof closure of the gastric wall incision. (2) Gastric incision healing 1 week after the procedure. Results: The mean intraperitoneal pressure increased 10.7 +/- 3.7 mm Hg during gastric insufflation when the air leak test was performed before closure compared with 0.9 +/- 0.8 mm Hg after transmural closure of the transgastric access site with T-bars (P <.001). Fluid leak tests demonstrated no leakage of liquid contrast from the stomach into the peritoneal cavity after closure. Necropsy in 1 week confirmed completeness of the gastric closure in all animals with full-thickness healing and no spillage of the gastric contents into the peritoneal cavity. Limitations: Leak tests were only evaluated oil an animal model. Conclusions: Fluid and air leak tests are simple techniques to evaluate in vivo the adequacy of the transluminal access site closure after NOTES procedures. Leak-proof gastric closure resulted in adequate tissue approximation and full-thickness healing of the gastric wall incision.
