We report a rare case of a small-bowel lymphangioma causing massive gastrointestinal (GI) bleeding that we successfully diagnosed and treated using double-balloon enteroscopy (DBE). An 81-year-old woman suffering from repeated GI bleeding of unknown origin underwent a capsule endoscopy at a previous hospital. She was suspected of having bleeding from the jejunum, and was referred to our department for diagnosis and treatment. An oral DBE revealed a 20 mm × 10 mm, regularly surfaced, white to yellowish, elongated, pedunculated jejunal polyp with small erosions at 10 cm distal to the ligament of Treiz. Since no other source of bleeding was identified by endoscopy in the deep jejunum, an endoscopic polypectomy (EP) was performed for this lesion. A subsequent histopathological examination of the resected polyp showed clusters of lymphatic vessels with marked cystic dilatation in the submucosa and the deep layer of the lamina propria mucosae. These characteristics are consistent with the typical features of small-bowel lymphangioma with erosions. Although clipping hemostasis was performed during EP, re-bleeding occurred. Finally, a complete hemostasis was achieved by performing an additional argon plasma coagulation.

Increasing numbers of patients with hepatocellular carcinoma (HCC) have been reported in Japan. In this paper, we investigated the role of hepatitis C virus (HCV) in HCC and the reason for the increase, using patients admitted to our university hospital from 1945 to 1992. 99 (73%) of 135 patients with HCC were positive for anti-HCV. Prospective studies demonstrated that 22 of 158 (14%) patients with chronic hepatitis C, and 31 of 70 (44%) cirrhotic patients with anti-HCV developed to HCC during the follow-up period (10.1 ± 3.3 and 7.3 ± 3.5 years, respectively). Prolonged survival of cirrhotic patients during past decades would also contribute to the increasing number of HCC cases as well as the number of HCV infections in Japan.

Conclusion: Our study is one of the largest evaluating cholangiocarcinoma patients treated with definitive SBRT. We found approximately 20% of patients experienced regional lymph node failure. In addition, there were high rates of distant failure despite the majority receiving chemotherapy. Our new approach of ENI encompassing regional draining lymphatics may help to decrease rates of distant failure and improve outcomes in this highrisk patient population.
