Visceral obesity was found to be an independent risk factor of colorectal adenoma, and insulin resistance was associated with the presence of colorectal adenoma.

Visceral adiposity measured by VAT, VAT/SAT, and waist circumference is associated with an increased risk of IBS, especially of IBS-D. However, neither SAT nor BMI are associated with an increased risk of IBS.

Upper gastrointestinal (GI) stents are increasingly being used to manage upper GI obstructions. Initially developed for palliative treatment of esophageal cancer, upper GI stents now play an emerging role in benign strictures of the upper GI tract. Because recurrent obstruction and stent-related complications are common, new modifications of stents have been implemented. Self-expandable metal stents (SEMS) have replaced older plastic stents. In addition, newly designed SEMS have been developed t

Although there were differences in the frequency of occurrence, various adverse reactions were confirmed in using all 4 COVID-19 vaccines, even with the BNT162b2 (Pfizer-BioNTech) vaccine. Caution is needed, and further research should be continuously conducted.

Obesity, visceral adiposity, and sarcopenia showed additive effects on MS prediction. Subjects with obesity, visceral adiposity, or sarcopenia were significantly associated with the increased risk of MS after adjustment for multiple confounders. Increasing skeletal muscle and reducing visceral fat may be strategies for the prevention or treatment of MS.

Visceral adiposity as measured by the VAT area and VAT/SAT ratio is associated with an increased risk of FD.

Although there are general guidelines on endoscopic biopsy for diagnosing gastric neoplasms, they are predominantly based on outdated literature obtained with fiberscopes without analyses specific to tumor characteristics.This study aims to comprehensively characterize the contemporary endoscopic biopsy by determining the diagnostic yield across different lesion morphologies and histological stages, especially exploring how the number and site of biopsy may influence the overall yield.Biopsy sam

La resistance a la chrysomele du liard, Chrysomela scripta F., d'un clone non transgenique de Populus ×euramericana, 'Ogy', et de trois lignees transgeniques 'Ogy' a ete evaluee par des experiences d'alimentation in vitro sur de jeunes plants obtenus par culture de tissus. La resistance des lignees transgeniques a ete evaluee par ses effets sur la surface foliaire consommee et le poids des larves. La surface foliaire consommee et le poids des larves differaient entre jeunes plants temoins et tra

AD showed a significant effect on the biologics-free survival of patients with IBD and especially the UC subtype. Further mechanistic research is required to elucidate the pathogenesis of AD on the clinical course of IBD.

These results demonstrate that PEIT is therapeutically useful in patients with HCC less than 4 in number and less than 3 cm in diameter. However, since multiple or large tumors are associated with low tumor-free survival or high local recurrence rates, PEIT for these tumors and the subsequent post-treatment follow-up should be performed carefully.

Background/Aims: Risk assessment by mitotic count in the gastrointestinal stromal tumor (GIST), the most common mesenchymal neoplasm, is important. EUS-guided fine- needle aspiration cannot obtain sufficient tissue for determination of mitotic count, but An EUS-guided Tru-Cut biopsy (EUS-TCB) can. The aim of this study was to evaluate clinical role of EUS-TCB in differential diagnosis of mesenchymal neoplasm and risk assessment of GIST. Methods: We prospectively enrolled 18 patients who were dia

목적: 위장관 간엽 종양 중 가장 흔한 위장관 간질 종양의 치료방침 결정에서 중요한 악성 위험 인자는 종양의 크기와 세포 분열 지수이고, 세포 분열지수 산정에는 충분한 조직 채취가 필수적이다. 초음파 내시경하 대형침 생검은 충분한 조직을 얻을 수 있어, 기존의 초음파 내시경하 세침 흡인의 단점을 보완할 수 있는 새로운 방법이다. 본 연구에서는 위장관 간엽 종양의 감별진단과 위장관 간질 종양의 위험도 측정에서 초음파 내시경하 대형침 생검의 역할을 알아보고자 하였다. 대상 및 방법: 2005년 11월부터 2007년 7월까지 서울대학교병원에서 시행한 초음파 내시경에서 직경이 2∼5 cm인 위장관 간질 종양이 의심되는 경우, 초음파 내시경하 대형침 생검을 시행하여, 조직 채취율, 악성 위험도 및 합병증 등을 전향적으로 분석하였다. 결과: 총 18명이 연구에 포함되었고, 이중 2명에서 생검을 실패하였다, 생검을 시행한 16명에서 종양크기의 중앙값은 2.7 cm이었다. 진단에 적절한 조직 채취
