[A case of ruptured duodenal varices successfully treated by combination therapy with endoscopic clipping and balloon-occluded retrograde transvenous obliteration].

An 80-year-old woman with a history of chronic hepatitis B was referred to our hospital because of upper gastrointestinal bleeding of unknown origin. Dynamic computed tomography revealed liver cirrhosis and hepatofugal collateral vessels around the duodenum. Emergency esophagogastroduodenoscopy showed duodenal varices with an erosive spot, highly suggestive of a variceal rupture site. We immediately performed endoscopic clipping of the ruptured site to achieve temporary hemostasis. Ten days later, elective balloon-occluded retrograde transvenous obliteration (B-RTO) was performed to prevent recurrence. We describe a successfully treated case of duodenal variceal rupture managed by combination therapy with endoscopic clipping and B-RTO.

[A case of primary adenocarcinoma of small intestine responding to XELOX chemotherapy and leading to a partial metabolic response].

We report a case of adenocarcinoma of the small intestine responding to XELOX chemotherapy, leading to a partial metabolic response(PMR). The patient was a 58-year-old male with multiple peritoneal dissemination of adenocarcinoma of the small intestine. Chemotherapy with XELOX(L-OHP 130 mg/m² on day 1 , and capecitabine 1,000 mg/m2 on days 1-14)was performed. After 4 courses, a significant tumor reduction was obtained. This case suggests that chemotherapy with XELOX is a potential regimen for small intestinal adenocarcinoma.

[A case of alcoholic hepatitis diagnosed by a liver biopsy and successfully treated by corticosteroid therapy].

A 50-year-old man with a history of alcohol intake exceeding 80 g/day was admitted because of severe liver dysfunction and high fever. A rapid increase of transaminase with remittent high fever was observed several days after admission. Abdominal CT scan demonstrated a 22×20 mm mass in segment 8, highly suggestive of hepatocellular carcinoma. However, because the etiology of the liver dysfunction was still unknown, we performed a liver biopsy on the sixth day. Histological examination of the liver specimen showed marked granulocyte infiltration, Mallory bodies, and hepatocyte ballooning, all consistent with alcoholic hepatitis. We made a final diagnosis of alcoholic hepatitis and successfully treated him with corticosteroids. This case suggests that a liver biopsy has diagnostic value in alcoholic hepatitis, especially in cases in which the diagnosis is uncertain.

[A case of resected rectal cancer with hepatic node and multiple liver metastases effectively treated by preoperative modified FOLFOX6 and sLV5FU2 chemotherapy].

A 55-year-old male had complained of melena.Colonoscopy revealed a type 2 tumor at the rectum.CT demonstrated hepatic lymph nodes and multiple liver metastases(stage IV).Low anterior resection was performed(tub2, RsRa, circ, type 2, pSS, pN1, sH3, cHN1, sP0, cM0: fstage IV).The patient was treated with mFOLFOX6 and sLV5FU2 after operation.CT revealed a partial response after 14 courses of systemic chemotherapy.sLV5 FU2 therapy was converted to capecitabine because he experienced bone marrow suppression.CT showed that the liver metastases had enlarged but the hepatic lymph nodes disappeared.Right portal vein embolization was performed.After 4 weeks, right hepatectomy and hepatic lymph node dissection were performed.Preoperative chemotherapy with mFOLFOX6 seems beneficial as a neoadjuvant chemotherapy for hepatic lymph node-positive advanced colorectal cancer.

[A case of early poorly-differentiated neuroendocrine carcinoma of stomach].

A 45-year-old male was admitted to our hospital complaining of anemia. Gastric endoscopy showed a type IIa+IIc tumor at the anterior wall of the gastric angle. Based on the pathology of the biopsy specimen, poorly-differentiated adenocarcinoma was diagnosed. Computed tomography scans showed regional lymph node swelling. Distal gastrectomy with a D2 lymph node dissection was performed. On pathology, the tumor was immunohistochemically positive for chromogranin A and synaptophysin. The Ki67 index was 70%. The tumor was diagnosed as poorly-differentiated neuroendocrine carcinoma of the stomach. He was treated with S-1 and CPT-11. Neuroendocrine cell carcinoma of the stomach is rare and usually has a very poor prognosis. Thus, we are reporting this case of early poorly-differentiated neuroendocrine carcinoma of the stomach that was curatively resected and had 12-month survival without recurrence.
