Small gastrointestinal stromal tumour of the duodenum causing a life-threatening bleeding - A case report and review of the literature.

INTRODUCTION: Duodenal gastrointestinal stromal tumors (DGISTs) are mesenchymal tumors. Main presenting symptoms are gastrointestinal bleeding and non-specific abdominal pain. Surgical treatment is golden standard for treatment of DGISTs. Tumour location and size determine the surgical strategy. Recurrence rate depends on tumour location and completeness on removal. PRESENTATION OF CASE: 75 years old male fell ill with hematemesis, hemohesia and dizziness. Oesophagogastroduodenoscopy (EGD) did not reveal the source of bleeding. Upon admission, a second EGD was performed due to loss of consciousness and anaemia, which revealed only approximate source of bleeding in the third portion of the duodenum. The exact bleeding spot could not be reached and bleeding could not be controlled endoscopically. Patient was transferred to the operating room for an emergency explorative laparotomy. After extensive mobilisation of the duodenum a 2 × 2 cm intraluminal tumour with central bleeding ulceration was found in D3. The diseased part of the duodenum was excised and the duodenotomy was closed with interrupted sutures. Final pathohistological report confirmed gastrointestinal stromal tumour, pT1. Postoperative period was uneventful. DISCUSSION: Gastrointestinal stromal tumours are most common in males aged 60-65 years. Surgical treatment is a golden standard. Surgical approach depends upon tumor location and size. In case of major bleeding surgical procedure is lifesaving and diagnostics for staging purposes are omitted. CONCLUSION: Gastrointestinal stromal tumors are a potential source of life-threatening bleeding. In such cases an emergency operation is often indicated with aim to remove the tumour en bloc and achieve hemostasis as soon as possible.
