Bouveret's syndrome: successful endoscopic treatment of gastric outlet obstruction caused by an impacted gallstone.

Bouveret's syndrome is defined as gastric outlet obstruction caused by duodenal impaction of a large gallstone which passes into the duodenal bulb through a cholecystogastric or cholecystoduodenal fistula. This is a report of a 62 years old female who presented with complaint of persistent vomiting and upper abdominal pain for the last 5 days. Ultrasound abdomen was suggestive of pneumobilia.

Comparison of transesophageal endoscopic plication (TEP) with laparoscopic Nissen fundoplication (LNF) in the treatment of uncomplicated reflux disease.

Background: Transesophageal endoscopic plication (TEP) is a novel endotherapeutic approach in the management of gastroesophageal reflux disease (GERD). This non-randomized prospective study compares TEP with laparoscopic Nissen fundoplication (LNF).

Methods: Twenty-four consecutive patients treated with LNF, and 27 managed by TEP were studied.

Ursodeoxycholic acid inhibits interleukin 1 beta [corrected] and deoxycholic acid-induced activation of NF-kappaB and AP-1 in human colon cancer cells.

Deoxycholic acid (DCA) has been implicated in colorectal carcinogenesis in humans with effects on proliferation and apoptosis, mediated at least in part by activation of transcription factors nuclear factor kappa B (NF-kappaB), activator protein 1 (AP-1) and protein kinase C (PKC) enzymes. Ursodeoxycholic acid (UDCA) is reported to reduce the frequency of colonic carcinogenesis in ulcerative colitis patients. Hence, we postulated that it might differ from DCA in its regulation of these transcription factors.
