ObjectiveTo investigate the feasibility and safety of gastroscopic gastrojejunostomy assisted by traction. MethodsThree experimental pigs were randomly divided into non-survival group (1 pig) and survival group (2 pigs), and all underwent gastroscopic gastrojejunostomy assisted by dental floss external traction. Methylene blue leak detection was conducted in the non-survival group after postoperative autopsy, while pigs in the survival group had fluids on the third day after operation, and gastroscopic review was carried out one week later and autopsy was performed to evaluate the status of abdominal infection and histological formation of anastomosis site. ResultsAll three experimental pigs were successfully operated, with an operation duration of 24 to 41 minutes. Methylene blue leak detection was found to be negative in the non-survival group. Pigs in the survival group presented good postoperative condition. There were no signs of abdominal organ injury or infection at autopsy one week after operation. Histopathology revealed a large amount of fibrous tissue hyperplasia at anastomosis site, with tight connections and infiltration of inflammatory cells. ConclusionGastroscopic gastrojejunostomy assisted by dental floss external traction is safe and feasible, which is worthy of further study and improvement.
