Resección endoscópica de hamartoma gigante de glándulas de Brunner. Reporte de un caso

Brunner's gland hamartoma or hyperplasia is a rare benign neoplasm of the small intestine, usually small, that is discovered incidentally on an upper digestive endoscopy or imaging tests. When it reaches a large size, it can cause digestive bleeding or intestinal obstruction. The pathogenesis is unknown. The endoscopic presentation can be nodular, polypoid or a diffuse glandular proliferation with thickening of the duodenal wall, and may be mistaken for a malignant neoplasm. Endoscopic resections of large Brunner's gland hamartomas in the duodenum is little reported in literature, due to its low incidence and diagnostic difficulty. The surgical approach is associated to greater morbidity compared to an endoscopic approach. The case of a 62-year-old patient is reported, who presented melena and symptomatic anemia, secondary to a giant polyp in the duodenal bulb. The polyp was successfully resected endoscopically without complications, which made it possible to avoid a more extensive surgical procedure. Histopathological examination of the whole specimen showed a Brunner's gland hamartoma. Conclusion: Brunner's gland hyperplasia or hamartoma is a benign neoplasm that rarely produces symptoms. Large lesions can become symptomatic and a high clinical-endoscopic suspicion and an evaluation of the extension are necessary before applying any therapeutic procedure, in order to avoid complex surgeries and favor a complete and safe endoscopic resection.

Submucosal Lesion

Brunner’s gland hamartoma (BGH) is an uncommon benign tumor arising from alkaline-based mucin-secreting glands of the duodenum. These lesions are typically discovered incidentally during upper gastrointestinal endoscopy or radiological diagnostics, even though they can eventually lead (in the case of increasing size) to obstructive or hemorrhagic symptoms. We report the case of a 67-year-old Caucasian man with two episodes of melena and epigastric pain during the last month. Esophagogastroduodenoscopy revealed a large pedunculated and eroded polyp inside the antrum with a 2-cm-long stalk arising from the anterior wall of the duodenal bulb. Endoscopic ultrasonography showed a submucosal lesion with homogeneous hyperechoic parietal thickening and some central gaps. The muscularis was undamaged. No lymphadenopathy was observed. We performed an en bloc endoscopic resection of the polyp. The size of the whole piece was approximately 6 × 3 × 2 cm, pseudocapsulated and tough in consistency. In the case presented, the en bloc endoscopic removal was successful despite the size of the tumor.

Brunner's gland hamartoma is a very rare benign tumor arising from the Brunner’s gland of duodenum and is usually asymptomatic, but may present with the symptom of duodenal obstruction or upper gastrointestinal bleeding due to ulceration from the tumor, requiring endoscopic or surgical resection. In our study, we report the case of a 57 year-old male who presented with pain over epigastrium, recurrent vomiting, black stool and dizziness with a lowering of hemoglobin up to 7.5 gm/dl. The blood transfusion was done to raise the hemoglobin. The upper gastrointestinal endoscopy revealed a giant submucosal polypoidal mass with a thick short stalk in duodenal bulb causing almost complete obstruction of the lumen of duodenum and there was a superficial ulceration on the under-surface of the mass. The endoscopic ultrasound revealed a submucosal lesion arising from the echo layer three. The computed tomography of abdomen showed that the polypoidal mass was confined to the duodenal lumen with no significant lumphadenopathy and normal biliary and pancreas. The endoscopic polypectomy was attempted, but the lesion was too large to grab the polyp as a whole with the conventional snare. Hence, the repeated partial snare polypectomies were done, followed by submucosal dissection to ensure the complete removal of the mass. There were no complications after the procedure. The histopathology examination of the duodenal mass confirmed the diagnosis of Brunner’s gland hamartoma and showed the presence of Helicobacter pylori as well. The endoscopic treatment of giant Brunner’s gland hamartoma avoided the need of unnecessary more invasive surgical procedure.
