The participation rates were similar for sigmoidoscopy and FOBT. The detection rate for advanced neoplasia was three times higher following screening by sigmoidoscopy than by FOBT.

To assess the characteristics of chronic hepatitis in hepatitis B surface antigen (HBsAg) carriers with intrahepatic delta antigen, the hepatic histologic findings of 137 patients were reviewed; 101 patients were followed for 2 to 6 years. The predominant liver disease was chronic active hepatitis in 93 patients or cirrhosis in 32; minor forms of chronic persistent or lobular hepatitis were seen in 12 patients. Eight of the 26 patients with an initial diagnosis of cirrhosis died during the follow-up period. Cirrhosis developed in 31 of 75 patients (41%) without nodular regeneration seen in the first biopsy specimen; 5 of these patients died. Treatment with prednisone or azathioprine did not induce histologic amelioration of delta hepatitis or prevent cirrhosis. Chronic HBsAg hepatitis with intrahepatic expression of the delta antigen is an active, progressive disease unresponsive to conventional immunosuppressive treatment.

Background/AimsEndoscopic retrograde cholangiopancreatography (ERCP) is the standard approach for the management of biliary complications in liver transplant patients; however, its safety and efficacy have not been established in this setting. This study was performed to evaluate the safety and long-term efficacy of ERCP in transplant patients.MethodsThe case reports of 1,500 liver transplant patients were reviewed. Orthotopic liver transplantation (OLT) patients were matched 1:2 with non-OLT patients and followed-up for long-term outcome (median, 7.4 years).ResultsOf the 1,500 liver transplant patients, 94 (6.3%) underwent 150 ERCPs after OLT. Anastomotic strictures were present in 45 patients, biliary stones in 24, biliary leaks in 7, papillary stenosis in 2, and primary sclerosing cholangitis in 1. An ERCP success rate of 90.7% was achieved; biliary stenting led to resolution of the bile leak in 7/7 (100%) patients, and biliary stones were removed in 21/24 (87.5%) patients. In addition, 34 of 45 patients with anastomotic stricture underwent endoscopic dilation. We obtained complete resolution in 22/34 (64.7%) patients. OLT patients did not show a higher probability of complications (odds ratio [OR], 1.04), of pancreatitis (OR, 0.80) or of bleeding (OR, 1.34).ConclusionsERCP is safe and effective for the treatment of post-OLT biliary complications, has a low rate of pancreatitis and results in a durable effect.
