[Successful Treatment of Necrotizing Fasciitis Due to Ascending Colon Cancer-A Case Report].

A 70-year-old woman was brought to our hospital by ambulance because of severe groin pain on the right side. Computed tomography scan revealed a tumor in the ascending colon, intraperitoneal abscess spread to the subcutaneous tissues, and a large amount of pneumoderma. She was diagnosed with necrotizing fasciitis caused by penetration of ascending colon cancer and underwent lavage and drainage, right hemicolectomy, end ileostomy, and debridement of necrotic tissues on emergency.

Sonographic demonstration of wall thickness of the gallbladder in pediatric patients with pancreatico-biliary maljunction.

Background: Sonographic demonstration of extramural and intrapancreatic junction of the pancreatic and bile ducts, pathognomonic for pancreatico-biliary maljunction (PBM), is not easy in pediatric patients. We measured sonographic thickness of the gallbladder (GB) and retrospectively examined correlation of it with PBM.

Methods: Twenty-seven children with PBM were examined with conventional ultrasonography (US).

Monitoring of hepatic artery resistance index and optimal timing of liver transplantation for biliary atresia.

Purpose: Biliary atresia (BA) is diagnosed by ultrasound (US) examination of the hepatic artery and gallbladder. This study was designed to assess the usefulness of the hepatic artery resistance index (HRI) measured by Doppler ultrasonography (DUS) for prognostication of liver viability in children with BA.

Methods: Seventeen patients with non-correctable BA were examined by US and DUS before and after hepatoenterostomy to evaluate hepatic artery dynamics.
