Results: Fifty eight patients with 59 lesions underwent ESD successfully, 30(50.8%) lesions were en bloc resection, and 55(93.2%) lesions were removed completely. One ectopic pancreas on gastric antrum not completely removed as non-lifting sign positive after submucosal injection. Another two specimens form leiomyoma on corpus ventriculi and ectopic pancreas on gastric antrum removed incompletely.

Histological diagnosis of upper gastrointestinal lesions: 11 inflammation, 7 ectopic pancreas, 7 leiomyomas, Wnt inhibitor 3 polyps, 3 ulcer, a total of 5 cases of stromal tumors, fibrous histiocytoma, early carcinoma, solitary fibrous tumor, eosinophilic granuloma and hamartoma. Histological diagnosis of colorectal lesions: 16 adenoma, 5 carcinoid,1 inflammatory polyp, 2 canceration then received surgery. A total of 22 cases before the operation had histological biopsy, Consistent diagnosis rate before and after the procedure was 59.1% (n = 13), another 9 cases (40.9%) had a clear diagnosis relying on larger biopsy after the procedure. There were 3 cases (5.2%) with post-ESD bleeding, 2 of them occurred

within 24 h after ESD, 1 case showm symptoms On the sixth day after ESD. All of them were controled by endoscopic and medical treatment. One case (1.7%) with suspected gastric cancer had perforation during the procedure of ESD, Kinase Inhibitor Library mw after tanium clipping and then received laparotomy successfully. Median follow-up period was 5.7 (range, 1–23.5) month. Follow-up rate was 41.1% (23/56). There was a recurrence case of rectal adenoma in 14 follow-up months. Conclusion: ESD is effective and minimal invasive endoscopic techniques for removing gastrointesinal lesions. It allows en-bloc removal of large lesion and is associated with a higher diagnostic rate and a lower recurrence rate compared with endoscopic mucosal resection (EMR). ESD is technically more difficult and can result in more complication that may occur more lately. There was

a hige incidence of post-ESD bleeding selleck inhibitor 0n gastric antrum. Key Word(s): 1. ESD; 2.

Despite the extensive worldwide use, there are still differences related to the safety and long term results. The aim of this study is to evaluate the efficacy and safety in different types of gastric varices and discuss the right time for the first gastroscopy examination postoperatively.
