The average age was PI3K inhibitor 50.3 years, ranging from 12 to 69 years. type B was the most commonly observed type of biliary
obstruction after liver transplantation, accounting for 47.3% (44/93), and type A was the least commonly observed type of biliary obstruction after liver transplantation, accounting for 9.7% (9/93). And type C accounted for 23.7% (22/93)and type D accounted for 19.3% (18/93). Conclusion: A new endoscopic classification of biliary obstruction after liver transplantation is proposed that might help in determining the proper candidates for treatment. Key Word(s): 1.

the feasibility and efficacy of Applications of a small -caliber transnasal endoscopy Sirolimus for percutaneous endoscopic gastrostomy and gastrostomy tube replacement in patients with motor neuron disease (MND) or severe esophageal diseases. Methods: Between June 2005 and March 2012, in Peking University Third Hospital, 118 persom-times underwent percutaneous endoscopic gastrostomy (PEG) with the ‘pull’ method using conventional gastroscopy (69 cases) or a small-caliber transnasal endoscopy (49 cases), 44 persom-times underwent gastrostomy tube replacement using conventional endoscopy (37 cases) or through the abdominal-wall stoma with a small-caliber transnasal endoscopy (7 cases). Indications for PEG included MND, esophageal stricture, esophagotracheal Fistula, and anorexia nervosa. Results: PEG by ‘pull’ method achieved in 47 of 49 cases (95.92%) with small-caliber transnasal endoscopy (one faied becaused of dyspnea, one becaused of puncture failure), which achieved in 66 of 69 cases (95.65%) with traditionary endoscopy (3 patients failed because of dyspnea), There were no significant differences in the average procedure time between the two groups, but MCE公司 the patients in group of small-caliber transnasal endoscopy reported less discomfort
associated with the procedure. There were no complications of major hemorrhage, perforation or aspiration. Gastrostomy tube replacement achieved in 44 of 44 cases (100%). 7 of these underwent with a small-caliber transnasal endoscopy through the abdominal-wall stoma, and colonoscopy position made the procedure quick and easy, the average procedure time was 7 ± 1.5 min. Conclusion: Small -caliber transnasal endoscope reduces the discomfort of the procedure and is safer than conventional gastroscopy for PEG. Gastrostomy tube replacement through the abdominal-wall stoma with a small-caliber transnasal endoscopy was feasible, safe and simple procedure and reduced the pain and stress of patients.
