OBJECTIVE: The purpose of this study was to determine whether patients who develop a pancreatic fistula after pancreatoduodenectomy are more likely to have higher pancreatic fat levels than matched controls and if so, to investigate whether preoperative dual gradient-echo magnetic resonance (MR) imaging can be used to measure pancreatic fat and predict the development of postoperative pancreatic fistula. SUMMARY BACKGROUND DATA: Pancreatic fistula is a major complication and its most frequently

Recent studies on perioperative fluid administration in patients undergoing pancreaticoduodenectomy (PD) have suggested that increased fluid loads are associated with worse perioperative outcomes. The purpose of this study was to investigate the relationship between intraoperative fluid (IOF) administration and postoperative pancreatic fistula (POPF), and to determine additional risk factors affecting pancreatic fistula in patients undergoing PD.From 2005 to 2014, a total of 182 patients with va

Prediction of malignancy or invasiveness of branch duct type intraductal papillary mucinous neoplasm (Br-IPMN) is difficult, and proper treatment strategy has not been well established. The authors investigated the characteristics of Br-IPMN and explored its malignancy or invasiveness predicting factors to suggest a scoring formula for predicting pathologic results. From 1994 to 2008, 237 patients who were diagnosed as Br-IPMN at 11tertiary referral centers in Korea were retrospectively reviewed

Esophageal carcinoid tumors remain some of the rarest of all carcinoid tumors, with only several cases previously reported in the literature. The endoscopic mucosal resection of selected carcinoid tumors has been shown to be a valid, safe, and effective method of treatment. Endoscopic ultrasonography is the technique of choice to select patients eligible for endoscopic resection. Here, we report successful endoscopic mucosal resection of a low esophageal carcinoid tumor and review the relevant l

Our results suggest that the 2093T-2180C haplotype at the 3'UTR of megsin gene is associated with rapid disease progression in Korean IgAN patients. This is the reverse of the results from the Chinese IgAN patients. Further studies are strongly needed to elucidate the reasons of disparity.

Crohn's disease is characterized by chronic transmural inflammation of the bowel and is associated with serious complications, such as bowel strictures, abscesses, fistula formation, and perforation. As neither medical nor surgical therapy provides a cure for Crohn's disease, the primary goals of therapy are to induce and maintain remission and prevent complications. As a biologic agent, infliximab, a monoclonal antibody to tumor necrosis factor, is indicated for refractory luminal and fistulizi

Chromosomal alterations were frequently identified in both PDAC and IPMN with similar patterns. CEP18 gain and 17p and 18q deletions might be involved in the later stages of PDAC tumorigenesis. Chromosome 17p and 18q deletions might be excellent diagnostic markers.

Sarcopenic obesity (SO), which is defined as a high ratio of visceral adipose tissue to skeletal muscle, is a well-known risk factor for post-hepatectomy outcomes in patients with hepatocellular carcinoma. However, few studies have evaluated the effect of SO on postoperative outcomes in patients with hilar cholangiocarcinoma (CCC). This retrospective study aimed to evaluate the effect of preoperative SO on postoperative outcomes in patients with hilar CCC following major hepatectomy. Preoperativ

BACKGROUND/AIMS: Although general guidelines have suggested weight-based dosing of azathioprine (AZA, 2.5 mg/kg/day) for Crohn's disease (CD), a substantial number of patients develop bone marrow suppression. The aim of this study was to evaluate the maximum dose of AZA not based on weight but titrated according to the lower limit of leukocyte count for maintaining remission in patients with CD. METHODS: Among a total of seventy-eight patients with CD, who had been followed-up at Kosin Universit
