Background: Gastrointestinal Stromal Tumor (GIST) arises from the interstitial cells of Cajal. Stomach is most common site GIST. The usual presentations GIST are gastrointestinal bleeding and abdominal pain. GISTs in duodenum uncommon. Duodenal obstruction due to even more usually detected on endoscopy, however they can be missed routine endoscopy if located third part duodenum. Computed Tomogr...

Background and Aim: Nigella sativa with anti-inflammatory and antimicrobial effects is one of the most widely used medicinal plants that can be used as an alternative or adjunctive therapy due to many side effects of chemical drugs. The aim of this study was to evaluate the regenerative and protective effects of Nigella sativa from pathological point of view in rat gastrointestinal tract. Mate...

The objective of this study was to evaluate the effect eubiotics on intestinal morphology broilers. For purpose, 125 birds were divided into six groups with two replicates each (10 in replicate). Group A given a Basal diet. All except group challenged Salmonella enterica serovar Enteritidis. B provided basal diet, C fed Probiotic-added diet; D Prebiotics-based E essential oils plus and F organi...

various complications of hydatid cyst have been recognized to date. we have encountered one such complication-rupture of hydatid cyst to the duodenum­ leading to upper gastrointestinal bleeding in a 40 year old male, who referred with severe right upper quadrant (ruq) pain and gastrointestinal bleeding of a few hours' duration. laparotomy revealed a cyst (7 x 15 cm) in the left lobe of the...

Background and aims: In diagnosing inflammatory bowel disease, one of diagnostic way is upper gastrointestinal endoscopy, which helps in differential diagnosis of unspecified colitis as well. The aim of this study was to investigate the necessity of upper gastrointestinal endoscopy in patients with inflammatory bowel disease.   Materials and Methods: In this descriptive cross-sectional...

We assessed the ascorbic acid (AA) supplementation on the myenteric neurons in the duodenum of rats. Fifteen rats with 90 days of age were divided into three groups: control (C), diabetics (D) and ascorbic acid treated diabetics (DA). After 120 days of daily treatment with AA, the duodenum was submitted to the NADH-diaphorase (NADH-d) histochemical technique, which allowed us to evaluate the ne...

We describe a patient in whom an early carcinoma of the duodenum was able to be resected endoscopically. A 77-year-old man presented with epigastric pain. Upper gastrointestinal endoscopy revealed a mass in the duodenum, and the patient was admitted. A whitish nodular aggregated lesion, measuring 20 mm in diameter, was found in the second portion of the duodenum. Examination of a biopsy specime...

Intestinal motility was studied in two sheep by electronically recording pressure changes using open-ended p.v.c. tubes placed in the lumen of the intestine and connected to pressure transducers. Flow in the duodenum and ileum was studied concurrently with motility. Both duodenum and ileum showed two types of activity, one progressive and associated with a flow of digesta, and the other localiz...

Background. Duodenum injury is extremely rare complication of laparoscopic cholecystectomy with potentially fatal consequences. Methods. Over the past 13-year period, 3000 laparoscopic cholecystectomies were performed in our institution. Duodenum injury only occurred in one patient recently who had undergone gastrectomy owing to duodenal diverticulum. The diagnosis and management of this rare c...

Although nonsteroidal anti-inflammatory drugs often cause ulcers in the duodenum in humans, the role of cyclooxygenase (COX) isoforms in the pathogenesis of duodenal ulcers has not been fully elucidated. We examined in cats the 1) ulcerogenic effects of selective COX-1 (SC-560, ketorolac) and COX-2 (celecoxib, meloxicam) inhibitors on the gastrointestinal mucosa, 2) effect of feeding and cimeti...
