Duodenal gangliocytic
paraganglioma treated with endoscopic hemostasis and resection.J
Gastroenterol. 2004;39(3):277-83.
Gangliocytic
paragangliomas are exceedingly rare tumors that arise in close
proximity to the papilla of Vater. There are few reports of the
endoscopic resection of duodenal gangliocytic paraganglioma. A
61-year-old woman was admitted with a complaint of melena. Endoscopic
examination revealed a pedunculated submucosal tumor with erosion in
the third portion of the duodenum. Hemostasis, using a gold probe, was
performed. Nine days later, we successfully resected the tumor, using
endoscopic polypectomy. To determine the depth of tumor invasion,
endoscopic ultrasonography was used. The size of the tumor was 3.0 x
2.5 x 1.0 cm. A total of 25 cases of duodenal gangliocytic
paraganglioma have been reported in Japan. Generally, this tumor is
considered benign. However, resection was performed in many patients
because preoperative diagnosis was impossible. In Japan, no previous
studies have reported using endoscopic hemostasis, to our knowledge.
Our patient is the fourth in Japan to be treated by endoscopic
resection. We report on our patient, with a review of the literature.
