Delayed Perforation After Endoscopic Resection of Upper Gastrointestinal Tumors: CT Findings to Identify Patients Requiring Surgery.

Purpose: To determine the clinical and imaging factors associated with surgical treatment in patients with delayed perforation after endoscopic resection of upper gastrointestinal tumors.

Methods: We retrospectively included patients with delayed perforation after endoscopic tumor resection for gastric or duodenal tumors between January 2007 and December 2021 in a tertiary hospital. We compared the clinical, endoscopic, and CT findings of the surgical and conservative treatment groups.

Bowel function and quality of life after minimally invasive colectomy with D3 lymphadenectomy for right-sided colon adenocarcinoma.

Background: Changes in bowel function after right-sided colectomy are not well understood compared to those associated with left-sided colectomy or rectal resection. In particular, there are concerns about bowel function after right-sided colectomy with complete mesocolic excision, which has become popular in the West.

Aim: To evaluate the functional outcomes of patients who underwent right-sided colectomy with D3 lymphadenectomy for colon cancer.

Management of the complications of endoscopic submucosal dissection.

Endoscopic submucosal dissection (ESD) is currently widely accepted as a standard treatment option for early gastrointestinal neoplasms in Korea. However, ESD has technical difficulties and a longer procedure time than conventional endoscopic resection. So it may have a higher risk of complications than conventional endoscopic resection techniques.

Focal eosinophilic infiltration versus metastasis in the liver: comparison of MRI findings.

Backgrounds/aims: This article was studied to compare the MRI findings of focal hepatic eosinophilic infiltration and hepatic metastasis.

Methodology: Contrast enhanced MR images of 40 lesions in 15 patients with focal hepatic eosinophilic infiltration and 34 lesions in 17 patients with liver metastasis were reviewed retrospectively. The size, number and location of focal lesions were analyzed.

[A case of Salmonella liver abscess].

Liver abscess can be caused by bacterial, parasitic, or fungal infection. Amebic abscesses are more common, but pyogenic abscesses account for three quarters of hepatic abscess in developed countries. Most common pathogens of the pyogenic liver abscess are Escherichia coli, Klebsiella pneumoniae, Bacteroides, Enterococci, Streptococci, and Staphylococci.

Rescue of Helicobacter pylori-induced cytotoxicity by red ginseng.

Helicobacter pylori has been known to provoke gastric inflammation, ulceration, and DNA damage, based on which WHO defined H. pylori as a class I carcinogen. Although ginseng, the root of Panax ginseng C.

Dieulafoy's lesion of jejunum: presenting small bowel mass and stricture.

Dieulafoy's lesion is an uncommon cause of gastrointestinal bleeding. Hemorrhage occurs through mucosal erosion from an abnormally dilated submucosal artery. Although Dieulafoy's lesion is usually located in the stomach, it may occur anywhere in the gastrointestinal tract.

MR findings in eosinophilic infiltration of the liver.

Objective: This study describes the findings of magnetic resonance imaging (MRI) of focal eosinophilic infiltration of the liver.

Methods: Contrast-enhanced MR images of 8 patients with focal hepatic eosinophilic infiltration were reviewed retrospectively. We evaluated the signal intensity of focal lesions in T1-weighted and T2-weighted images and the pattern of enhancement in a dynamic contrast study.

[Effect of infliximab in the treatment of refractory inflammatory bowel disease with complication].

Background/aims: Many studies on infliximab have confirmed its efficacy in the remission induction and even maintenance in refractory and fistulizing Crohn's disease. We report the treatment efficacy of infliximab in Crohn's disease and ulcerative colitis refractory to steroid treatment and the complications of infliximab treatment.

Methods: We performed infliximab administration in 5 cases (3 Crohn's disease, 2 ulcerative colitis) refractory to systemic steroid treatment and 5 cases of Crohn's disease with fistula.

Blockage of HSP 90 modulates Helicobacter pylori-induced IL-8 productions through the inactivation of transcriptional factors of AP-1 and NF-kappaB.

Helicobacter pylori infection leads to significant inflammations in the gastric mucosa, which is closely associated with development of gastric cancer. Heat shock protein 90 (HSP 90) has been revealed to be critical for intracellular signaling that participates in inflammatory response as well as carcinogenesis. In this study, we investigated a regulatory role of HSP 90 in H.

[Suppressive effects of antioxidant DA-9601 on hepatic fibrosis in rats].

Background/aims: Oxidative stress is one of the important underlying mechanisms of hepatic fibrosis. DA-9601, the ethanol extracts of Artemisia asiatica, has been reported to possess strong antioxidative and cytoprotective actions. We tried to evaluate whether antioxidant can ameliorate dimethylnitrosamine (DMN)-induced hepatic fibrosis.
