Objective To evaluate the efficacy of endoscopic variceal ligation and somatostatin for esophageal varices bleeding.Methods Eighty patients with hepatic cirrhotic esophageal varices bleeding were allocated into two groups,forty in endoscopic variceal ligation(EVL)group and the others in somatostatin(stilamin)group.Results Initial hemostasis rates(including emergency hemostasis and no bleeding for 72 hours)and one-month rebleeding rates in EVL group and somatostatin group were 97.5% vs 80%(P0.05).The hepatic encephalopathy rates were 2.5% vs 15%(P0.05).Conclusion Endoscopic variceal ligation is superior to somatostatin for hepatic cirrhotic esophageal varices bleeding.EVL can lower the rate of hepatic encephalopathy.

Objective To study efficacy of L-ornithine-L-aspartate (Hepa-Merz) in treatment for nonalcoholic steatohepatitis (NASH) and its effect on lowering serum level of triglycerine MethodsTotally, 30 patients with nonalcoholic steatohepatitis diagnosed by liver function test, B ultrasound scanning and liver biopsy were treated by intravenous infusion of L ornithine L aspartate (Hepa Merz) 10 g daily for 21 days Activities of serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) and serum level of triglycerine (TG) were determined for all the cases before and after treatment Results Activities of serum ALT and AST and serum level of TG were restored to normal in 29 (96 7%) and in 28 (93 3%) of 30 patients, respectively, after treatment No serious adverse effects were found during treatment Conclusions L ornithine L aspartate (Hepa Merz) is a safe and effective drug in treatment for nonalcoholic steatohepatitis, and can lower serum level of triglycerine significantly

Objective To investigate the value of double-balloon enteroscopy and CT enterography for the diagnosis of intestinal Crohn disease ( CD ) . Methods Data of 125 patients with suspected CD undergoing double-balloon enteroscopy and CT enterography were reviewed. Diagnosis was made based on pathological,endoscopic findings and clinic follow-up results. Detection rates and diagnostic rates of double-balloon enteroscopy and CT enterography for intestinal CD were compared. Results The detection and diagnostic rates of intestinal CD by double-balloon endoscopy were 62. 4％( 78/125) and 94. 8％ ( 74/78) , respectively. The sensitivity, specificity and accuracy of double-balloon enteroscopy in the diagnosis of intestinal CD were 100. 0％, 92. 2％ and 96. 8％, respectively. The detection and diagnostic rates of intestinal CD by CT enterography were 44. 8％( 56/125 ) and 89. 3％ ( 50/56 ) , respectively. The sensitivity, specificity and accuracy of CT enterography in the diagnosis of intestinal CD were 67. 6％, 88. 2％ and 76. 0％, respectively. Both the detection rate and the diagnostic rate of double-balloon enteroscopy in intestinal CD were higher than those of CT enterography. Conclusion Double-balloon enteroscopy shows high application value for the diagnosis of intestinal CD, but CT enterography before enteroscopy can guide the selection of endoscopic approach, reduce economic expenditure and alleviate patients' pain, so CT enterography could be the first choice for intestinal CD patients with contraindications of enteroscopy.
