We report a unique case of synchronous double primary gastric cancer consisting of adenocarcinoma components with micropapillary features and composite glandular-endocrine cell carcinoma components. The patient was a 53-year-old man presenting with a 6-month history of epigastric pain and diarrhea. A subtotal gastrectomy was performed.

Purpose: The aim of this study was to define the capsules of synchronous multicentric small hepatocellular carcinomas (HCCs) with use of high-frequency intraoperative ultrasonography (IOUS).

Methods: Among the 131 consecutive patients undergoing hepatic resection and high-frequency IOUS for HCC, 16 synchronous multicentric small HCCs in 13 patients were histologically diagnosed in the resected specimens. High-frequency IOUS and pathologic findings of these lesions were compared, with particular focus on the presence and appearance of the capsule in or around each lesion.

Purpose: In about 1% of cases, incidental gallbladder cancers (iGBC) are found after routine cholecystectomy. The aim of this study is to compare clinical features of iGBC with benign GB disease and to evaluate factors affecting recurrence and survival.

Methods: Between January 1998 and March 2014, 4,629 patients received cholecystectomy and 73 iGBC patients (1.

Laparoscopic cholecystectomy (LC) is the treatment of choice for gallbladder stones. One of the major complications associated with LC is bile duct injury; ligation or cutting of a bile duct can result in significant segmental biliary obstruction with cholangitis or bile leak, which can progress to bile peritonitis or biliary fistula. Most postoperative bilomas and bile leaks can be treated by percutaneous drainage and decompression of the biliary system by endoscopic stent placement or nasobiliary drainage.

Systemic capillary leak syndrome (SCLS), also called Clarkson's disease is rare and life-threatening disorder of unknown etiology, which is a characteristic triad of hypovolemic shock, hemoconcentration, and hypoalbuminemia. Unexplained capillary leakage from the intravascular to the interstitial space, which has been estimated up to 70% of the intravascular volume, is the proposed mechanism. Because the pathogenesis is unknown, it is diagnosed clinically after exclusion of other diseases that cause systemic capillary leak and no efficacious pharmacological treatment has been clearly established.

Non-typhoid salmonellosis is an infectious disease caused by Salmonella species other than Salmonella typhi. Although the usual clinical course of non-typhoid salmonellosis is a benign self-limiting gastroenteritis, these bacteria are especially problematic in immunocompromised individuals, including patients with malignancies, human immunodeficiency virus, or diabetes, and those receiving corticosteroids or other immunotherapy agents. In addition to enteric symptoms, Salmonella species give rise to extra-intestinal complications, including self-limiting arthritis, which appears 1 to 3 weeks after the onset of infection and lasts from a few weeks to several months.

The conventional management of pancreatoenteric fistulas and pancreatic abscess with aggressive surgery or percutaneous drainage catheter placement are associated with increased surgery-related morbidity and mortality, and a longer hospitalization. We report here a case of successful closing pancreatoduodenal fistula, which remained open after the percutaneous catheter drainage of pancreatic abscess, by using vascular coil embolization and fibrin glue injection. This procedure is a less invasive, more effective and better tolerated strategy for the management of pancreatoenteric fistula in a selected group of high risk patients and needs further investigation.

Hepatocellular carcinoma (HCC) is the second most common cause of male cancer death in Korea, where the major etiology, chronic hepatitis B virus infection, is endemic. With a high incidence of unresectable HCCs and a low cadaveric organ donation rate, the number of adult living-donor liver transplantations (LDLTs) has increased rapidly, by tenfold, over the past 10 years, as an alternative to deceased-donor liver transplantation (DDLT) in Asia, including Korea. Currently, HCC accounts for more than 40% of the indications for adult LDLT as the associated decompensation cirrhosis or unresectable HCC with 2.

Background And Aims: Hepatitis C virus (HCV)-associated cirrhosis is an increasingly frequent indication for liver transplantation (LT). However, HCV recurrence is universal and this immediately occurs following LT, which endangers both the graft and patient survival. We investigated the frequency of posttransplant recurrence of HCV infection and the patient-graft survival, and we analyzed the responses to ribavirin and interferon therapy in the patients with recurrent HCV infection after living donor liver transplantation (LDLT).
