Insights
Adult small intestine duplication is rare. Double-balloon enteroscopy (DBE) successfully diagnosed a stomach-like jejunal duplication in an 18-year-old male, aiding prompt treatment.
Area of Science:
- Gastroenterology
- Pediatric Surgery
- Diagnostic Endoscopy
Background:
- Gastrointestinal duplications are congenital anomalies rarely diagnosed in adults.
- Preoperative diagnosis of small intestinal duplications presents significant challenges.
Observation:
- An 18-year-old male presented with chronic, unexplained upper abdominal pain and vomiting.
- Diagnostic evaluations failed to identify the cause of his symptoms.
Findings:
- Double-balloon enteroscopy (DBE) revealed a stomach-like jejunal duplication with ectopic gastric mucosa.
- Enteroclysis via DBE identified a tubular structure adjacent to the jejunum.
- Surgical resection of the jejunal segment resolved the patient's symptoms.
Implications:
- DBE is a valuable tool for diagnosing rare adult small intestinal duplications.
- This case highlights the importance of considering intestinal duplication in adults with persistent gastrointestinal symptoms.
- Accurate diagnosis facilitates timely surgical intervention and symptom resolution.
Abstract:
Gastrointestinal duplications are congenital malformations that are usually observed in pediatric patients. Diagnosis in adulthood is quite rare, and preoperative diagnosis of gastrointestinal duplication is difficult, particularly in the small intestine. We encountered an extremely rare adult case of duplication of the jejunum, which showed a stomach-like form diagnosed using double-balloon enteroscopy (DBE). The patient was an 18-year-old male who had been experiencing upper abdominal pain and vomiting repeatedly without any triggers for 3 years. Various examinations were performed, but no cause of symptoms was found. DBE revealed a narrow opening of the lumen at the upper jejunum, and the lumen was covered with mucosal folds similar to those of the stomach. Enteroclysis via DBE showed a tubular structure on the mesenteric side of the jejunum. We diagnosed a jejunal tubular duplication with ectopic gastric mucosa and underwent partial small bowel resection. The patient's abdominal symptoms resolved. From this, DBE can be a useful tool for diagnosing intestinal duplication in adults. We believe that this case and literature review will facilitate the accurate and prompt diagnosis of small intestinal duplication.
