One of the causes of congenital incomplete duodenal obstruction is the presence of duodenal membranes. This condition requires a high index of suspicion for an early and accurate diagnosis. We present two cases of duodenal obstruction with initial diagnosis of foreign bodies that were surgically intervened and where incomplete duodenal membranes were an incidental finding. The clinical course o...

At operations on 150 patients the duodenal bulb was examined for local features which predispose it to peptic ulceration. A surgeon now has the opportunity to study the duodenum in its natural state and normal situation in both healthy and ulcerated conditions. When gastroenterostomy or partial gastrectomy were routinely used for the cure of duodenal ulcers, the bulb was either left unopened or...

Background: Cytotoxin-associated gene A (CagA)-positive strains of Helicobacter pylori are associated with gastroduodenal diseases. Evidences have suggested that the type of H pylori CagA EPIYA motifs may be associated with specific disorders (i.e., gastritis, peptic ulcer, or gastric cancer).  We investigated the prevalence of different EPIYA motifs (A, B, C, or D) in H. pylori strains is...

Choledochodoudenal fistula is an uncommon bilio-enteric with clinical presentation ranging from having no symptoms to frank cholangitis. The causes of choledochodoudenal are multiple, bile duct stones being the most common. Duodenal ulcer rarely source fistula. Clinical diagnosis defies acumen, and high-quality imaging including endoscopic or radiologic required for confirmation. Management not...

Chemotherapy for multiple primary cancers is challenging. We describe a case of synchronous duodenal cancer with lung cancer harboring an epidermal growth factor receptor (EGFR) mutation treated with erlotinib and S-1, an oral fluoropyrimidine agent. A 78-year-old woman with advanced EGFR-mutated lung adenocarcinoma was simultaneously diagnosed with duodenal adenocarcinoma. After the treatment ...

This paper shows that in Nigeria as in England there is an excess of blood group O in patients with duodenal ulcer.

The incidence of duodenal ulcer, especially Helicobacter pylori-negative duodenal ulcer, strongly increases with age. In humans, telomere length shortening is considered to be one critical factor in cellular senescence and organ survival. In this study, we compared basal and stimulated gastric acid and duodenal HCO(3)(-) secretory rates in aged late-generation (G(3)) telomerase-deficient (mTERC...

Small bowel tumors are rare tumors. Duodenal tumors occur more commonly compared with other small intestinal tumors. To summarize the clinicopathological features of duodenal tumors, in the present study 44 cases of duodenal tumors were collected, and the comparative clinicopathological characteristics between tumors of the ampulla and non-ampulla, the choice of treatment, and differences in th...
