[Incomplete membrane stenoses of the duodenum (author's transl)]

Area of Science:

• Pediatric Surgery
• Gastroenterology
• Congenital Anomalies

Background:

• Incomplete duodenal membrane stenosis is a rare congenital anomaly.
• It can present with varied clinical symptoms, often mimicking other gastrointestinal issues.
• Associated abnormalities in the urogenital and skeletal systems can occur.

Purpose of the Study:

• To report two pediatric cases of incomplete duodenal membrane stenosis.
• To illustrate the variable clinical presentations and diagnostic findings.
• To emphasize the successful surgical management of this condition.

Main Methods:

• Case report of two pediatric patients.
• Diagnostic imaging including contrast studies.
• Surgical intervention involving membrane resection.

Main Results:

• Both patients presented with incomplete duodenal membrane stenosis.
• Case 1 showed ileus and duodenal diverticulum with biliary/pancreatic reflux.
• Case 2 had limited symptoms but impressive intraduodenal pseudodiverticulum on X-ray.
• Both underwent successful surgical correction.

Conclusions:

• Incomplete duodenal membrane stenosis exhibits significant variability in clinical presentation.
• Characteristic radiographic signs aid in diagnosis.
• Surgical resection of the membrane is an effective treatment.
• Early diagnosis and intervention are crucial for favorable outcomes.
