    Abstract:
    Objective The aim of the present study is to investigate the role of double-balloon enteroscopy in the diagnosis and surgical treatment of metastatic small bowel tumors. Patients We retrospectively reviewed the records of 13 patients with metastatic small bowel tumors among 376 patients who underwent double-balloon enteroscopy from June 2005 to March 2017 in our hospital. Results The primary lesion sites were the lung (n=9), kidney (n=2), stomach (n=1) and duodenum (n=1). The clinical presentations were anemia requiring blood transfusion (n=10), obstructive symptoms (n=2), and no symptoms (n=1). The locations of the metastatic small bowel tumors were the jejunum (n=7), ileum (n=1), and both sites (n=5). The histological diagnosis of the metastatic tumor was made from biopsy specimens taken with double-balloon enteroscopy from all 11 patients whose condition permitted a biopsy. In seven patients, the findings on double-balloon endoscopy were determinants of the kind and extent of surgical treatment performed. Four patients had multiple metastatic small bowel tumors, and all were able to be removed surgically with guidance from preoperative tattooing at double-balloon endoscopy. After operation, blood transfusions were no longer needed in four of six patients who had required preoperative transfusions for the treatment of anemia, and one patient with intestinal obstructive symptoms was able to resume oral intake. Conclusion Double-balloon endoscopy was useful for making a histological diagnosis and directing surgical treatment in patients with metastatic small bowel tumors. Surgical treatment afforded palliation of symptoms in five patients.
