Duplication Cyst in the Third Part of the Duodenum Presenting with Gastric Outlet Obstruction and Severe Weight Loss

الملخص EN

Duodenal duplication is a rare developmental abnormality which is usually diagnosed in infancy and childhood, but less frequently in adulthood.

We report a case of a 16-year-old female with a duplication cyst in the third part of the duodenum.

The patient presented with symptoms of gastric outlet obstruction, including severe anorexia and weight loss.

The diagnosis was made preoperatively by CT scan and upper endoscopy.

The cyst was successfully treated by marsupialization on the duodenum using a GIA stapler.

Duodenal duplication presents with a wide variety of symptoms.

Although illusive, many cases can be properly diagnosed preoperatively by using the appropriate imaging modalities.

Treatment choices are tailored according to the size and location of the cyst, in addition to its relation to adjacent structures.

The outcomes are favorable in the majority of patients.
