The patient was treated conservatively with IV heparinization, followed by an oral anticoagulant agent.

A Novel Auxiliary Device for Preventing Band Slippage After Laparoscopic Adjustable Gastric Banding: Infra-Band Fixation Using S-Loop.

Background: Band slippage is known to be a troublesome complication of laparoscopic adjustable gastric banding (LAGB), often requiring surgical intervention. To prevent band slippage, a new auxiliary device "S-loop" was developed.

Methods: From July 2010 to January 2014, a total of 814 LAGBs were performed by a single surgeon.

[A case of hepatocellular carcinoma presented as a huge intrahepatic hematoma].

Spontaneous intrahepatic bleeding is a rare condition. In the absence of trauma, intrahepatic hematoma may be due to underlying liver disease. We report a case of hepatocellular carcinoma in the patient who had huge intrahepatic hematoma without definite intrahepatic tumor at the time of initial presentation.

[Clinical and epidemiological analysis of a 20-year experience of surgically treated gallstone patients].

Background/aims: The aim of this study was to investigate the epidemiological characteristics and changing patterns of gallstone disease over the last 20 years.

Methods: Four thousands and twenty gallstone patients who had received surgery at Seoul National University Hospital (1981 to approximately 2000) were analyzed according to time of treatment; period I: 1981 to approximately 1985 (831 cases), period II: 1986 to approximately 1990 (888 cases), period III: 1991 to approximately 1995 (1,040 cases) and period IV: 1996 to approximately 2000 (1,261 cases). Data from 13 institutes in Korea reporting 13,101 gallstone cases were also reviewed with literature to elucidate the nation-wide trends.
