A Case of Abdominal Abscess in Crohn's Disease: Successful Endoscopic Demonstration of an Obscure Enteric Fistula by Dye Injection via a Percutaneous Drainage Catheter.

Abdominal and pelvic abscesses occur in approximately 10-30% of Crohn's disease patients during the course of the disease; most of these abscesses have an enteric communication. For this condition, percutaneous abscess drainage (PAD) rather than emergency surgery has recently been recognized as a valuable procedure for initial treatment. However, in cases wherein the abscess is accompanied by an enteric fistula, the recurrence of abscess might be inevitable without the management of the enteric fistula.

[A case of endocrine cell carcinoma of the ileum: sonographic findings and clinical outcome].

A 56-year-old man, who had been complaining of diarrhea for several months, was admitted for further examination of a hepatic tumor. A needle biopsy of the hepatic tumor suggested metastatic carcinoid tumor. The primary tumor was found in the ileum by extracorporeal sonographic examination and a barium meal study.

Inhibition of cholesterol crystallization under bilirubin deconjugation: partial characterization of mechanisms whereby infected bile accelerates pigment stone formation.

Pigment gallstones have been reported to be closely associated with biliary tract infection. We previously reported that addition of unconjugated bilirubin (UCB), which is deconjugated by beta-glucuronidase in infected bile, could enhance cholesterol crystal formation in supersaturated model bile (MB). The present study evaluated the effect of beta-glucuronidase on the processes of pigment gallstone formation and cholesterol crystallization.

Impaired gallbladder mucosal function in aged gallstone patients suppresses gallstone recurrence after successful extracorporeal shockwave lithotripsy.

Background: Absorption of water, as well as emptying of bile, are important functions of the gallbladder. We studied the changes of gallbladder function with age in gallstone patients and their influence on the outcome of extracorporeal shockwave lithotripsy (ESWL).

Methods: (i) A total of 123 consecutive patients with complete stone clearance by ESWL were examined.
