ABSTRACT
Small bowel arteriovenous malformation (AVM) is a rare vascular lesion, which should be considered in patients presenting with gastrointestinal bleeding, as it is a high-flow arterial lesion that can cause life-threatening bleeding. Although a primary endoscopic examination is performed in cases of suspected small bowel bleeding, the diagnosis of the causal lesion is sometimes difficult. We are presenting a case of small bowel AVM that could not be diagnosed endoscopically but was successfully detected using multiphase CT images with an appropriate protocol. The AVM diagnosis was confirmed using digital subtraction angiography. An endovascular coil is placed in the draining vein as a surgical resection marker. The AVM was resected successfully without any complications.
ABSTRACT
Oral uracil and tegafur plus Leucovorin(UFT/LV)therapy is one of the standard adjuvant chemotherapies for colorectal cancer, and is widely used without any serious adverse events. Herein, we describe a case of UFT/LV-induced acute liver failure in a 75-year-old woman who underwent laparoscopic sigmoidectomy for sigmoid colon cancer. She was diagnosed with advanced colon cancer and lymph node metastasis by postoperative histopathological analysis, and adjuvant chemotherapy was initiated. After 30 days of commencing the therapy, the patient visited our hospital with complaints of severe diarrhea and difficulty in food intake. The apparent cause of these symptoms was unclear on computed tomography(CT), and mild liver damage was revealed in blood test results. The hepatic disorder gradually progressed after the hospitalization, and the condition was diagnosed as acute hepatic insufficiency. Additionally, obvious atrophy of the liver parenchyma and significant ascites were confirmed on CT. Two months later, the platelet count decreased markedly, but fortunately, no bleeding occurred. There has been no recurrence since 2 years after the surgery without any additional adjuvant therapy.

A female in her late 50s experienced dyspnea and was transported by an ambulance. Her hemoglobin score was low, and CT imaging showed a giant tumor in her stomach. The tumor perforated her liver and invaded the abdominal wall and duodenum around the Treitz ligament. She required surgery because of the massive hemorrhage due to the tumor. Total gastrectomy with lateral segmentectomy of the liver and resection of the duodenum and the ileum around the Treitz ligament were performed. At 1.5 months after surgery, chemotherapy for malignant lymphoma was successfully initiated.
