BACKGROUND & AIMS Data vary on the progression of low-grade dysplasia (LGD) in patients with Barrett's esophagus (BE); in patients with LGD, we investigated the incidence of high-grade dysplasia (HGD) and esophageal adenocarcinoma (EAC) and compared progression in patients with different forms of LGD (prevalent vs incident and multifocal vs unifocal). We(More)
BACKGROUND & AIMS The risks of dysplasia and esophageal adenocarcinoma (EAC) are not clear for patients with nondysplastic Barrett's esophagus (NDBE); the rate of progression has been overestimated in previous studies. We studied the incidences of dysplasia and EAC and investigated factors associated with progression of BE. METHODS The BE study is a(More)
AIM To study the angle between the circular smooth muscle (CSM) and longitudinal smooth muscle (LSM) fibers in the distal esophagus. METHODS In order to identify possible mechanisms for greater shortening in the distal compared to proximal esophagus during peristalsis, the angles between the LSM and CSM layers were measured in 9 cadavers. The outer(More)
Hemoperitoneum without evidence of organ damage is a rare complication of colonoscopy. It is most frequently seen in association with splenic rupture due to traction on the splenocolic ligament. In our case, we present a 48-year-old cirrhotic man who developed peritoneal bleeding during a diagnostic colonoscopy for iron deficiency anemia. However, he was(More)
We report a case of secondary sclerosing cholangitis that manifested itself during pregnancy. A tentative diagnosis of intrahepatic cholestasis of pregnancy was considered, but after her third delivery, a liver biopsy and imaging, as well as review of past records, confirmed the diagnosis of secondary sclerosing cholangitis. Maternal and fetal outcomes of(More)
