[A Case of Pylephlebitis with Pseudomonas aeruginosa Sepsis and Liver Abscess Secondary to Diverticulitis].

Pylephlebitis, or suppurative thrombophlebitis of the portal venous system, is a rare condition occurring secondary to abdominal infections such as diverticulitis. Pylephlebitis can be diagnosed via ultrasonography or CT scan, and is characterized by the presence of a thrombus in the portal vein and bacteremia. However, the diagnosis may be delayed due to the vague nature of the clinical symptoms, causing morbidity and mortality due to pylephlebitis to remain high.

[Successful Management of Periampullary Diverticular Bleeding with Hemoclipping Using Side-viewing Endoscope during Endoscopic Retrograde Cholangiopancreatography].

Periampullary diverticulum is commonly found during endoscopy and can occur at any age although its prevalence increases with age. Periampullary diverticular bleeding is a rare and difficult to diagnose during clinical practice because of its unique appearance and location. This often can lead to massive bleeding and interfere with adequate bleeding control.

Mechanism of action of cholecystokinin on colonic motility in isolated, vascularly perfused rat colon.

Background/aims: It is generally believed that cholecystokinin (CCK) stimulates colonic motility, although there are controversial reports. It has also been suggested that postprandial peptide YY (PYY) release is CCK-dependent. Using a totally isolated, vascularly perfused rat colon, we investigated: (1) the roles of CCK and PYY on colonic motility, (2) to determine if CCK modulates PYY release from the colon to influence the motility and (3) to clarify whether the action of CCK and PYY on colonic motility is mediated via the influence of cholinergic input.

[A case of subphrenic abscess with ileal fistula caused by metastatic adenocarcinoma of unknown origin].

Usual sources of subphrenic abscess with intestinal fistula are previous abdominal operation, inflammatory bowel disease and malignancy. Reported cases of intestinal fistula caused by adenocarcinoma were complicated by direct invasion. In this report, a 70-year-old male had a subphrenic abscess with intestinal fistula and the cause was a metastatic adenocarcinoma of unknown origin.

[Liver abscess caused by Gemella morbillorum].

Gemella morbillorum, an anaerobic-to-aerotolerant Gram-positive coccus, is a normal flora of the oral cavity, respiratory tract, urogenital organ and gastrointestinal tract, and infections caused by this organism are unusual. It has been associated mainly with endocarditis and bacteremia, and rarely with arthritis, spondylodiscitis, meningitis, brain abscess and septic shock. Liver abscess caused by G.
