Primary hydatid cyst of the small intestine masquerading as intestinal duplication in a child.

Hydatid disease or hydatidosis is a worldwide zoonosis disease caused by the tapeworm of and still widely endemic in Tunisia especially in rural areas where the sheep-dog cycle is dominant. It is an important public health problem in the pediatric age group causing significant morbidity and mortality. We report a case of primary hydatid cyst of the small intestine in a child and we want to highlight the difficulty that we meet in the diagnosis despite the contribution of imaging.

Alimentary tract duplications in children: report of 16 years' experience.

Background: Alimentary tract duplications (ATDs) are a rare condition in children, characterised by a large pathogenic, clinical, and histological polymorphism. Surgical observation and pathologic evaluation of the resected specimens are the only way to confirm the diagnosis. In this study, we want to analyse the anatomical, clinical and therapeutic aspects of this entity.

Duodenal adenocarcinoma in a 10-year-old boy.

Peptic oesophageal stricture in children: management problems.

Background: Peptic oesophageal stricture (PES) is a serious complication of gastroesophageal reflux disease (GERD) in childhood. The treatment of PES is still controversial, ranging from simple oesophageal dilations to resection/anastomosis of the stenotic portion of the oesophagus. In this study, we want to share our experience with 11 children with GERD and PES.
