2%), carcinoma (n = 5, 5.7%), polyp (n = 5, 5.7%) and angiodysplasia (n = 1, 1.1%). Conclusion: Urgent colonoscopy for LGIB results in high rate of incomplete examinations. Even when causes
were found, only half of them had an impact on the clinical management GSI-IX in terms of endoscopic intervention or change in immediate clinical decision. Therefore, decision to perform urgent colonoscopy for LGIB should be individualized, taking into consideration relative importance of timing of intervention versus colonic preparation and overall impact in clinical management of patients.

Hyaluronic acid solution injection can be an additional endoscopic modality for controlling difficult cases when other techniques failed. We evaluated the feasibility of hyaluronic acid solution injection in various bleeding cases retrospectively Methods: We evaluated 12 cases which we used Hyaluronic acid solution injection
for stop bleeding. Hyaluronic acid solution injection was performed as follows: (1) generation of 20 cc of a 0.2% hyaluronic acid solution by mixing hyaluronic acid and saline; (2) precise identification of the bleeding focus; (3) injection of 5 cc of hyaluronic acid solution into each point surrounding the bleeding focus;
and (4) the lesion was washed and checked for further bleeding. Bafilomycin A1 ic50 Cessation of bleeding was measured based on clinical findings or endoscopic examination Results: Immediately following Hyaluronic acid solution injection, bleeding was controlled in 11 out of 12 cases. There was no evidence of renewed bleeding and proved complete healing was found in 11 cases, although we were unable to do follow-up endoscopy in all cases. Conclusion: Hyaluronic acid solution injection is a simple MCE and efficient method for controlling bleeding at the site of a sclerotic ulcer base, so it needs to be considered as a next step before deciding radiologic intervention or surgery.

Methods: 85 hepatic cirrhosis Esophageal Variceal Bleeding patients were randomly divided into 3 groups Endoscopic Variceal Selerotherapy group, Endoscopic Variceal Ligation group and combined treatment group, observing hemostasis and dispearence of Esophageal varices and side effect rate. Results: Three hemostasis methods by endoscope show no significant differences in hemostasis success rate (P > 0.05).
