Role of baseline adenoma characteristics for adenoma recurrencein patients with high-risk adenoma

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.

Chronic liver diseases and iron: a concise review with emphasis on hypotransferrinemia and hypohepcidinemia.

Iron studies in chronic liver diseases (CLDs) have a long history. Currently we can mention certainties, uncertainties, and hopes related to this topic. It is certain that iron metabolism problems and hepatic siderosis are frequent in CLDs and they get more frequent as CLD progresses, but true iron overload is rare. There are conflicting literature data on the mechanism of siderosis, the role of iron in CLD pathogenesis, and the potential benefits of iron removal. We may hope that pharmacological approaches targeting iron metabolism disorders of CLD will be actively evaluated in the future. In this review, we aimed to present a general outlook of this extensively studied topic.

Analysis of Non-Small Bowel Lesions Detected by Capsule Endoscopy in Patients with Potential Small Bowel Bleeding.

Gastrointestinal (GI) bleeding cases in whom source cannot be identified after conventional upper and lower GI endoscopy are defined as potential small bowel bleeding. We aimed to search for lesions in the reach of conventional endoscopy in patients to whom video capsule endoscopy (VCE) had been applied for potential small bowel bleeding. 114 patients who had VCE evaluation for potential small bowel bleeding between January 2009 and August 2015 were retrospectively evaluated. Mean age of the patients was 55 ± 17 years. Female/male ratio is 39/75. In 58 patients (50.9%) bleeding lesion could be determined. Among these 58 patients 8 patients' lesions were in the reach of conventional endoscopes. Overall these 8 patients comprised 7% of patients in whom VCE was performed for potential small bowel bleeding. Among these 8 patients 5 had colonic lesions (4 angiodysplasia, 1 ulcerated polypoid cecal lesion), 2 had gastric lesions (1 GAVE, 1 anastomotic bleeding), and 1 patient had a bleeding lesion in the duodenal bulbus. Although capsule endoscopy is usually performed for potential small bowel bleeding gastroenterologists should always keep in mind that these patients may be suffering from bleeding from non-small bowel segments and should carefully review images captured from non-small bowel areas.

An Unusual Reason for Gastric Variceal Hemorrhage: Wandering Spleen.

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.

Evaluation of gastric polyps detected by endoscopy: a single-center study of a four-year experience in Turkey.

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.

Acute pancreatitis caused by bortezomib.

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.

Anticoagulant-induced intramural duodenal haematoma presenting with upper-gastrointestinal haemorrhage.

Warfarin is an anticoagulant agent known to have a common complication, bleeding. Intramural intestinal haematoma is an uncommon incidence of warfarin-induced haemorrhage. Abdominal pain is its most frequent symptom and presentation with upper-gastrointestinal haemorrhage is rarely seen. Here, we present a 67-year-old male who was admitted to the hospital with active upper-gastrointestinal haemorrhage. In this case, the cause of bleeding has been attributed to duodenal intramural haematoma due to warfarin overuse.

Serum iron parameters in cirrhosis and chronic hepatitis: detailed description.

BACKGROUND/AIMS: Serum iron parameters are affected by liver disorders. It is believed that the tests are unreliable in chronic liver disease, and systemic iron overload should be evaluated histologically in these patients. However, the effect of severity of chronic liver disease on serum iron parameters has not been evaluated. Similarly, differences between liver disease- and iron overload related iron parameter changes have not been clarified. We aimed to describe the effect of severity of chronic liver disease on serum iron tests and to elucidate the differences of liver disease- and iron overload-related iron parameter changes. METHODS: Commonly used serum iron parameters were studied in patients with cirrhosis, chronic viral hepatitis and in persons with confirmed hemochromatosis. Cirrhosis cases were categorized according to Child-Pugh classification. RESULTS: We found that cirrhotic persons of any Child-Pugh class had deviations from normal results. Patients with chronic hepatitis had normal serum iron parameters. Total iron binding capacity decreased as liver disease progressed from hepatitis toward Class C cirrhosis (r= -0.53, p<0.001). Changes in ferritin and transferrin saturation were essentially opposite to this trend (r=0.3, p=0.01 and r=0.47, p<0.001, respectively). Serum iron level was lower in cirrhosis compared to hepatitis. Increased transferrin saturation and ferritin levels resembling iron overload were limited to Class C cirrhotics. Patients with true iron overload could be easily differentiated from these cases by hyperferremia. CONCLUSION: Aberrant serum iron test results indicate cirrhotic stage in chronic liver disease. Cirrhosis and systemic iron overload cause characteristically different changes in serum iron parameters.
