Results: The overall mean procedure time and median tumor size

were 93.6 ± 55.9 minutes and 31.0 ± 13.7 mm. The rate of en bloc resection was 91.5%. The rate of perforation and post-operative hemorrhage were 3.8% and 2.1%. The mean tumor size and the rate of severe fibrosis and perforation were significantly higher, and the en bloc resection rate was significantly lower, in the difficult ESD group. The rates of perforation and difficult cases in the first period were 11.0% and 31.0% and these rates were improved in the fifth period (11.0%, 1.6%). Conclusion: The efficacy of colorectal ESD was confirmed to large colorectal tumors. The rates of difficult cases and perforation decreased according to learning curve. Key Word(s): 1.

ZHANG Affiliations: Department of Emergency, Xijing Hospital of Digestive Diseases, Fourth Military Medical University Objective: The present study aimed to explore the etiology and characteristics of septic find more shock. Methods: Clinical record data base of Xijing Hospital of Digestive Diseases was screened for septic shock cases. Retrospective analysis was performed. Results: Totally 39 patients with septic shock were enrolled from December 2008 to December 2012. All the patients suffered from abdominal peritonitis,acute cholangitis and intestinal

obstruction, which resulted in 12 deaths. The mortality was 30.77%, and the average death age was 58.84 years. Among them, 8 patients were greater than 60 years old, accounting for 47.05% mortality. For patients less than 60 years old, the mortality was 19.04%. Twenty one patients received surgical operation, 3 of which died, indicating mortality of 16.67%, much lower than the average mortality. Eighteen patients did not receive operation, 9 of which died, suggesting mortality of 50%, higher than the average mortality. Conclusion: Surgical operation and age are MCE公司 two important factors affecting the survival rate of patient with septic shock and intestinal obstruction. Surgical operation was recommended for patients having operation indications.

Preoperative diagnosis is important because recognition of an appendiceal mucocele could alter clinical management.
