RÉSUMÉ
Objective To evaluate the perforation repair method of purse-string suture with single channel after gastroscopy endoscopic submucosal resection (ESD) in treating gastric submucosalal stromal tumor originating from muscularis propria lay of gastric fundus. Methods 15 patients with GIST from gastric fundus muscularis propria were treated with ESD. The diameters of tumors were from 1.5 ～ 3.5 cm. Purse-string suture with single channel gastroscopy was performed for the gastric wall perforation during ESD. Results All patients underwent repair successfully. The procedure time was 10 ～ 15 min. No severe complications occurred. Conclusion Purse-string suture with single channel gastroscopy is a feasible and effective perforation repair method during ESD of gastric fundus.
RÉSUMÉ
Objective To investigate the effectiveness of hemostatic-clip-assisted method during ERCP with ampulla around duodenal diverticulum. Methods 25 patients with ampulla around duodenal diverticulum encountered cannulation difficulty, 11 cases underwent with clip-assisted method, 14 cases with ordinary ways. Number of successful cases, cannulation time, post-operation complication were analyzed. Results All the 11 cases succeeded in clip group. 12 patients succeeded in none-clip group. Cannulation time between the two groups were discrepant. There was no difference in number of successful cases and post-operation complication rate. Conclusion Successful application of hemostatic clip help to expose and facilitate cannulation of an ampulla around a duodenal diverticulum.
