BACKGROUND/AIMS Proximal serrated polyp (SP) is one of potential explanations for the failure of colonoscopy to prevent all interval cancers. The aims of our study were to determine the prevalence of proximal SP in Korea and to investigate clinical factors associated with the proximal SP detection in average-risk people undergoing screening colonoscopy.

The influence of body mass index (BMI) on the outcome of patients with colorectal cancer (CRC) is largely unknown, particularly in an Asian population. Therefore, we investigated the influence of BMI on survival of patients who underwent surgical treatment for CRC in Korean population. This prospective cohort study included CRC patients who underwent(More)
Nonampullary sporadic duodenal adenomas (NSDAs) are uncommon mucosal neoplasms with malignant potential. Recently, endoscopic treatment is used for NSDA with increasing frequency. This study therefore aimed to evaluate the efficacy and safety of endoscopic treatment for NSDA. A total of 36 NSDAs in 35 consecutive patients were endoscopically eradicated at(More)
There are often discrepancies between the pretreatment evaluation of gastric neoplasms by endoscopy with biopsy and the final diagnosis of resected specimen in terms of pathology and depth of invasion. We evaluated the spectrum of discrepancies between pretreatment and posttreatment diagnosis which may deliver significant differences on clinical practice. A(More)
Schwannomas are rare tumors derived from the cells of Schwann which form the neural sheath. Some patients with gastrointestinal schwannoma have been previously reported in the literature. However, schwannomas of the colon are extremely rare. We herein describe a case of schwannoma of the colon. A 49-year-old woman was admitted with complaint of abdominal(More)
In this paper we propose a framework for code generation from B formal specification based on component based method. First, software components can be derived form B abstract machines according to their relativity. Then, by using proved translation rules the elicited software components are translated into code directly. Finally, all the software(More)
Gastrointestinal stromal tumors (GISTs) and non-GIST subepithelial tumors (SETs) account for about 75 and 25 % of gastric hypoechoic SETs ≥2 cm, respectively. Therefore, identifying preoperative predictive factors for GISTs are required to refine surgical indications. We performed a retrospective review of 375 surgically resected gastric hypoechoic SETs ≥2(More)
BACKGROUND/AIMS Acute hepatic failure (AHF) is one of the most serious complications of transcatheter arterial chemoembolization (TACE). The aims of this study were to investigate risk factors of AHF after TACE and to establish a predictive model for AHF. METHODS In the evaluation set, a total of 820 patients who underwent TACE as a first treatment for(More)
BACKGROUND/AIMS Limited data exist regarding the natural history of duodenal carcinoid tumors and the efficacy of endoscopic treatment. METHODS A total of 27 patients with duodenal carcinoid tumors were enrolled. All tumors were located outside the periampullary region and were ≤10 mm in size. 11 patients underwent endoscopic mucosal resection (EMR) and(More)
