Therefore, EMR-CI may be effective modality in cases with hard to perform ESD. Key Word(s): 1. ESD; 2. EMR; 3. EMR-CI; 4.

selleck chemicals with pronase granules during gastroendoscopy. Methods: Methods: 240 patients were divided into a treantment group and a control group randomly in order. Observe and assess the visibility score during gastroscopy, and the adverse reactions. Results: Results: Premedication with pronase (the treatment group) significantly reduced (P < 0.05) the visibility score in comparison with that obtained for premedication without pronase (the controlled group). In terms of security, incidence rate of transient adverse reaction is 3.3%, the result of the two groups are the same. Conclusion: Conclusions:

Premedication with pronase Idasanutlin in vivo granules effectively improved gastroscopy visualization, can significantly reduce the gastric mucus before gastroscopy and improve the detection of small lesions of stomach. Premedication with pronase granules has high security. Key Word(s): 1. Pronase granules; 2. Gastroscopy; 3. Visibility; 4.

decompression and debridement with endoscopic treatment in elder patients in acute biliary pancreatitis. Methods: 52 elder patient with acute biliary pancreatitis underwent early endoscopic treatment, and another 48 elder patients with acute biliary pancreatitis were treated conservatively. The clinical therapeutic effects were observed and the data we treated with statistics between two groups. Results: Elder patients with early endoscopic treatment have 96.6% of success in operation, and no ERCP related severe complication or death. The decrease of serum amylase levels, the times in the disappearance of abdominal pain, Tolmetin the time of the disappearance of jaundice, the days of the hospitalization, and rate of complication were significantly shorter in the early endoscopic treatment group than in the control group. The difference between two groups has statistical significance. The difference in the decrease of serum amylase levels, the times in the disappearance of abdominal pain, the time of the disappearance of jaundice between two groups has no statistical significance. Conclusion: Early biliary decompression and debridement with endoscopic treatment can degrade the acute biliary pancreatitis’ elder patients case fatality rate and complication, and it conduces to patients convalescence early and has a shortenet length of stay.
