Current evidence suggests that there are three sphincters that regulate the flow of chyme from stomach to the duodenum. We investigated the hypothesis whether a fourth 'physiologic sphincter' exists at the duodeno-jejunal junction. The pressure response of the jejunum, duodeno-jejunal junction and duodenum to individual balloon distension of the jejunum and duodenum was recorded in 28 healthy s...

The duodenum is largely responsible for the breakdown of food in the small intestine, using enzymes. Duodenal submucosal glands, which in general produce a mucous secretion, exist in all mammalian species. These glands are located in the submucosa of the proximal duodenum. The study aimed to demonstrate the morphological and histochemical properties of duodenum and duodenal submucosal glands in...

This study was conducted to investigate the effects of thyme essential oil and enzyme supplementation on rations with two different energy (wheat or corn) protein resources (soy rapeseed meals) gut morphology digestibility broiler chickens. Three hundred eighty-four male Ross-308 chickens were used a 23 factorial arrangement treatments according completely randomized design. The morphological e...

Renal cell carcinoma (RCC) metastasis to duodenum is very rare and only a few case reports are available in the literature. We here reported a patient with solitary duodenal metastasis presented with melena six years after right nephrectomy. The patient underwent upper gastrointestinal endoscopy showing ulcerative mass at the second portion of duodenum and biopsy of this mass was consistent wit...

food intake of rats increases during pregnancy. this requires changes in the structure of the small intestine to absorb additional food. the aim of the present study was to investigate the morphological changes in the layers of small intestine in rats during pregnancy. duodenum, jejunum and ileum of 18 pregnant sprague-dawley rats (day 7, 14 and 21 of pregnancy) were collected. villous height a...

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 ...

The goal of research. To analyze some features peptic ulcer the stomach and duodenum in children, depending on type constitution. Material methods We examined 58 children aged 12-18 years with a diagnosis and/or duodenum, who underwent endoscopic examination, Hp was detected biopsy aero test. Results. Peptic disease more often asthenic (67.2%), less hypersthenic (17.3%) normosthenics (15.5%). V...

A 55-year-old Japanese man without dyslipidemia underwent esophagogastroduodenoscopy screening. He was diagnosed with reflux esophagitis, atrophic gastritis, and multiple gastric ulcers. In addition, scattered white villi were seen in the superior duodenal angle. No white villi were seen in any other parts of the duodenum. Esophagogastroduodenoscopy performed three months after Helicobacter pyl...

We report two patients with primary adenocarcinoma of the duodenum who underwent successful pancreatico-duodenectomy (modified Whipple operation). One patient died from an unrelated cause three years following surgery whilst the other remains well and clinically free of disease 3 years after resection. An aggressive surgical policy in patients with this rare tumour seems justified.

Gangliocytic paragangliomas are rare benign tumors which are usually encountered in the second portion of the duodenum. Histogenesis of these tumors is incompletely understood. Patients usually present with upper gastrointestinal bleeding. The endoscopic features of gangliocytic paraganglioma do not differ from those of other submucosal tumors. Therefore, they can be diagnosed histologically by...
