Ultrasonography-guided percutaneous radiofrequency ablation for treatment of a huge symptomatic hepatic cavernous hemangioma.

Hepatic cavernous hemangioma is the most common benign tumor of the liver. Appropriate management of this tumor remains a controversial topic. We have accumulated a number of cases with successful management of local hepatic tumors.

[Laparoscopic and percutaneous ultrasound guided radiofrequency ablation for hepatocellular carcinoma: a preliminary study].

Background/aims: Radiofrequency ablation (RFA) is emerging as a new therapeutic method in the management of hepatocellular carcinoma (HCC). We report the results of 64 patients with a follow-up interval of 3 to 19 months.

Method: Sixty-four patients with 82 nodules underwent ultrasound guided RFA.

[The usefullness of percutaneous transluminal balloon angioplasty in the management of budd-Chiari syndrome].

Background/aims: Membranous obstruction is the most common cause of Budd-Chiari syndrome in Orientals. Recently, percutaneous transluminal balloon angioplasty (PTBA) has been successfully applied as a treatment of membranous obstruction. We evaluated etiologies and clinical manifestations in our cases and the usefulness of PTBA.

Prognostic factors of the long-term survival after transjugular intrahepatic portosystemic shunt in the treatment of gastric and esophageal variceal bleeding.

Transjugular intrahepatic portosystemic shunt (TIPSS) is a promising method of treatment for gastric or esophageal variceal bleeding. This study was performed to determine the prognostic factors contributing to the survival of patients after TIPSS for gastric or esophageal variceal bleeding. One hundred and fifty-five patients who underwent TIPSS between September 1991 and March 2001 were followed up by clinical examination, upper gastrointestinal endoscopy, and Duplex sonography.

Endoscopic incision of a septum in a case of spontaneous intramural dissection of the esophagus.

Intramural dissection of the esophagus is a rare esophageal disorder that is characterized by a long laceration between the esophageal mucosa and submucosa but without perforation. It reveals characteristic radiologic and endoscopic features. The etiology of intramural dissection of the esophagus remains uncertain.
