Duodenal malformations are the third commonest cause of intestinal obstruction in infants. A spectrum of intrinsic obstructive lesions within the duodenum ranges from atresia to congenital bands. Rarely, duodenal malformations may first present in adulthood. Less than 70 cases of duodenal web presenting in an adult have been reported in the literature. In 10 patients the presentation was associ...

Duodenal duplication cyst is a rare anomaly, totaling only 4% to 12% of gastrointestinal duplications, and is usually encountered during infancy or in early childhood. Most are commonly located posterior to the first or second portion of the duodenum. Presenting signs and symptoms include vomiting, decreased oral intake, periumbilical tenderness, abdominal distention, obstructive jaundice, acut...

We report a rare case of incomplete congenital duodenal obstruction (Type 1 duodenal atresia) in association with situs inversus totalis presenting with gastric perforation in a neonate. The infantogram was suggestive of perforation with air under diaphragm along with dextrocardia. On exploration, a pin point perforation at fundus near lesser curvature along with situs inversus was noted. Prima...

INTRODUCTION Duodenal duplication is a rare congenital malformation. Although more frequent in childhood, it may rarely be observed in adulthood. Pre-operative diagnosis can be difficult. PRESENTATION OF CASE We report the case of a 52-year-old man with a duodenal duplication cyst, who was misdiagnosed even after a primary surgery. Definitive treatment needed an extensive diagnostic workup an...

Our aim is to present a case with initial diagnosis of non-classified type duodenal atresia operated in our clinic. A patient with prenatally suspected to be duodenal atresia was explored. At laparotomy type 3 duodenal atresia was found between 2nd and 3rd parts of duodenum. In addition, a web was detected distal to the atresic part. Duodenoduodenostomy together with web excision was performed....

Duodenal perforation in childhood is a rare condition with a high mortality rate if not treated surgically. Primary gastroduodenal perforation is frequently associated with peptic ulcer and exhibits a positive family history. Helicobacter pylorus is the most significant agent. Secondary gastroduodenal perforation may be a finding of specific diseases, such as Crohn disease, or more rarely may b...

A conceivable concept for the development of duodenal ulcers in Helicobacter pylori (H. pylori) infected subjects is presented in this chapter. The concept includes an explanation of the fact that only a minority of all H. pylori-infected subjects will develop a duodenal ulcer. Helicobacter pylori infection of the antrum induces a hypersecretion of gastric acid secretion, giving rise to gastric...

To determine whether the social class differences in duodenal ulcer frequency may be explained by differences in physical activity at work, the energy expenditure during work, smoking habits, and social class were compared in 76 recently diagnosed duodenal ulcer patients and in age and sex matched community controls. As anticipated, the relative risk of duodenal ulcer showed significant associa...

When dealing with gastric cancer with duodenal invasion, gastrectomy with distal resection of the duodenum is necessary to achieve negative distal margin. However, rupture of an ultralow duodenal stump necessitates advanced surgical skills and close postoperative observation. The present study reports a case of an early duodenal stump rupture after subtotal gastrectomy with resection of the who...

Portal hypertension and associated complications cause significant morbidity and mortality in cirrhotic patients. Variceal development is the most important portal hypertension related complication. Varices most commonly occur around the gastroesophageal junction, but ectopic varices may develop in many gastrointestinal and extra-gastrointestinal localizations. Duodenum is one of the most commo...
