The mechanisms underlying acute pancreatitis have not been well elucidated. Over the last 20 years, there has been increasing awareness regarding the role played by oxidative stress in acute pancreatitis, but it is less well defined in human clinical trials. The aim of this study was to identify the relationship between antioxidants and acute pancreatitis.We performed a cross-sectional trial on patients with mild acute pancreatitis. The study population consisted of 53 patients with mild acute pancreatitis and 55 healthy controls. Serum paraoxonase, arylesterase activity, total antioxidant status, total oxidant status and thiol levels were measured, and oxidative stress index was calculated.Paraoxonase, arylesterase activity, thiol and total antioxidant status levels were significantly lower in the acute pancreatitis group than in the control group (p = .024, p .001, p .001, p = .010, respectively). Oxidative stress index and total oxidant status levels were higher in the acute pancreatitis group than in the control group, but the difference was not statistically significant (p = .135, p = .253, respectively).This study demonstrates that decreased antioxidant levels are associated with mild acute pancreatitis. No association was observed between mild acute pancreatitis and total oxidant status.

BACKGROUND/AIMS The dynamic thiol/disulfide homeostasis plays pivotal roles in many physiological mechanisms in an organism. We aimed to investigate whether dynamic thiol/disulfide homeostasis changes among patients with acute pancreatitis. MATERIALS AND METHODS This prospective trial contained 45 patients with acute pancreatitis and 45 sex-and age-matched healthy volunteers as control group. Thiol/disulfide homeostasis parameters were measured by a novel and automated assay, and detected results were compared between the two groups. RESULTS Disulfide/total thiol percent ratio and disulfide/native thiol percent ratios were significantly higher in acute pancreatitis group; besides the native thiol, total thiol levels and native thiol/total thiol percent ratios were significantly lower (for all p < 0.001). CONCLUSION The thiol/disulfide homeostasis is impaired in acute pancreatitis with a shift toward the oxidative status, and this deficiency might be a pathogenic factor in acute pancreatitis. The correction of this thiol/disulfide imbalance may be a new target in the management of acute pancreatitis.

Gastrointestinal stromal tumors (GIST) are mesenchymal tumors of the gastrointestinal tract. Although bleeding is one of the most symptoms seen in GIST, significant acute bleeding is an unusual finding. Here in, three cases with gastrointestinal bleeding due to GIST are presented. Of these patients one had duodenal, one had jejunal and the other had ileal GIST. The duodenal GIST was detected by endoscopy while the jejunal GIST was found by capsule endoscopy and the ileal GIST was shown on magnetic resonance enterography. All patients underwent surgery and the diagnoses of GISTs were confirmed by histopathological evaluation.

Background/aim: The present observational study aimed to determine the predictive value of 3-year recurrence adenoma characteristics at baseline conventional colonoscopy in patients with high-risk adenoma.Materials and methods: A total of 47 patients with high-risk adenoma at baseline colonoscopy were followed up and underwent a surveillance colonoscopy at 3 years. Correlations between adenoma recurrence and baseline adenoma characteristics (size, number, histological features, and location) were analyzed.Results: Among 135 patients with high-risk adenoma, 47 patients (35%) who underwent surveillance colonoscopy at 3 years following baseline colonoscopy were included in the study. In these 47 patients, at least one new adenoma was detected in 19 (40.4%) patients, and new advanced adenomas were detected in 5 (10.6%) patients during the surveillance colonoscopy. No significant difference was found in patients who had adenoma recurrence versus those who did not in terms of size of adenomas (P = 0.143), number of adenomas (P = 0.562), histological properties of adenomas (P = 0.658), or locations of adenomas (P = 0.567).Conclusion: Baseline adenoma characteristics were not associated with the recurrence of adenomas or advanced adenomas in patients with high-risk adenoma.

Background/Aims: The aim of this study was to evaluate the gastric polyps detected by endoscopy in our institution with respect to their frequency, size, anatomic location, presence of dysplasia, and histopathologic features. Materials and Methods: Records of a total of 14,240 patients who underwent endoscopy between January 2008 and January 2012 were reviewed retrospectively. Of the 14,240 patients, 174 determined to have at least 1 histopathologically proven polyp were included in the study. Results: Three hundred eleven gastric polyps were found in 174/14,240 (1.2%) patients (1.79 polyps per patient). Gastric polyps were found most commonly in the antrum (41.5%). Of all gastric polyps, 189 (60.8%) were less than 1 cm. Histopathologically, the most common polyp type was hyperplastic (n: 261, 83.9%), followed by adenomatous (n: 23, 7.4%). Eight (34.8%) of the adenomatous polyps showed dysplasia, and in 4 (17.4%) of these cases, the dysplasia was high-grade. Nineteen (6.1%) of all gastric polyps were identified to be fundic gland polyps. Conclusion: According to this study from Turkey, the majority of polyps detected by endoscopy was solitary, smaller than 1 cm, and found in the antrum; furthermore, the most common type was a hyperplastic polyp.

Drug-induced pancreatitis has been reported rarely. Bortezomib is a selective and reversible proteasome inhibitor used for the treatment of patients with multiple myeloma (MM). Recently, one case report about acute pancreatitis (AP) caused by bortezomib was published in the international literature. Herein we report a case of AP in a 67-year-old male on bortezomib therapy. On the fourth day after the first administration of bortezomib, the patient admitted to the hospital with symptoms of AP. The common etiological factors for AP were all excluded. Than the patient was diagnosed as bortezomib-induced pancreatitis.

Wandering spleen is the displacement of the spleen due to the loss or weakening of the ligaments of the spleen and is seen very rarely with an incidence of less than 0.5 %. It can cause portal hypertension, but gastric variceal hemorrhage is a quite rare condition within the spectrum of this uncommon disease. We report a 22-year-old woman with wandering spleen presenting with life-threatening gastric variceal hemorrhage. Her diagnosis was made by computerized tomography. Endoscopic therapy was not adequate to stop the bleeding, and urgent splenectomy was performed. After surgery she has been well with no symptoms until now.

Background/Aims: There are a limited number of studies including the impact of antiplatelet drugs use on hospital outcomes for nonvariceal upper gastrointestinal bleeding. The aim of this study was to determine the effect of anti-aggregant, anti-coagulant and non-steroidal anti-inflammatory drugs upon hospital outcomes in patients with peptic ulcer bleeding. Materials and Methods: The patients under treatment with antiaggregant, anticoagulant or non-steroidal anti-inflammatory drugs were categorized as exposed group (n = 118) and the patients who were not taking any of these drugs were categorized as non-exposed group (n = 81). We analyzed the data of drug intake, comorbid disease, blood transfusion, duration of hospital stay, Blatchford/total Rockall score and diagnosis of patients. Results: In total, 199 patients were included. Of these 59.3% (exposed group) were taking drugs. The patients in exposed group were significantly older than those in non-exposed group (62.9 ± 17.3 years; 55.5 ± 19.3 years, P = 0.005, respectively). Mean number of red blood cell units transfused (2.21 ± 1.51; 2.05 ± 1.87, P = 0.5), duration of hospital stay (3.46 ± 2.80 days; 3.20 ± 2.30 days, P = 0.532) and gastric ulcer rate (33% vs 23.4%, P = 0.172) were higher in exposed group than in non-exposed group but the differences were not statistically significant. Total Rockall and Blatchford scores of the patients were significantly higher in exposed group than in non-exposed group (3.46 ± 1.72 vs 2.94 ± 1.87, P = 0.045; 10.29 ± 3.15 vs 9.31 ± 3.40, P = 0.038). Conclusıon: Our study has shown that anticoagulants, antiaggregants and nonsteroidal anti-inflammatory drugs do not effect duration of hospital stay, red blood cell transfusion requirement and rebleeding for peptic ulcer bleeding.
