Abstract
Duodenal Adenocarcinomas (DA) represent approximately 0.3% of all malignant gastrointestinal tumors. DA is the most common site for adenocarcinoma in gastrointestinal track. The most common site of DA within duodenum is the 2nd part of duodenum. A high degree of suspicion is required for the diagnosis of third/fourth part DA. Push enteroscopy is the definitive diagnostic tool for third/fourth part DA. We discussed a case of adenocarcinomas third part of the duodenum with brief discussion on controversies in optimal surgical management.
Highlights
Bowel obstruction involving third part of duodenum (D3) is rarely encountered in clinical practice
In children benign pathologies such as malrotation, duodenal web, duodenal perforated diaphragm, internal paraduodenal hernia, and tropical jejunoilitis are the usual causes of D3 obstruction [1]
Around half of all the small bowel adenocarcinomas are located in the duodenum [6],[7]
Summary
Bowel obstruction involving third part of duodenum (D3) is rarely encountered in clinical practice. The malignant causes of adult D3 obstruction are adenocarcinoma, carcinoid, lymphoma, leiomyosarcoma and gastrointestinal stromal tumor [3]. Adenocarcinoma of small bowel accounts for less than one per cent of all gastrointestinal malignancies [3],[4],[5].
