RESUMO
BACKGROUND: Eosinophilic gastrointestinal disorders (EGIDs) are a rare group of inflammatory disorders that can occur anywhere along the gastrointestinal tract, from the esophagus to the rectum. In particular, those with malignant or benign tumors are extremely rare. CASE PRESENTATION: A 62-year-old man was referred to our hospital with a chief complaint of abdominal fullness. The peripheral white blood cell count was 19,400/µL, and the eosinophil count was 13,300/µL. Abdominal computed tomography showed massive ascites. Cytology of the ascitic fluid showed a large amount of eosinophils and no malignancy. Upper and lower gastrointestinal endoscopies were performed on the suspicion of EGIDs, and colon cancer with no other abnormalities was found. The biopsies of the cancer lesions and non-cancer lesions also showed significant differences in eosinophil counts per high-power field (HPF) between the cancer and non-cancer lesions (median 77.5 [IQR 52-115] vs. 40.5 [35-56]/HPF, P < 0.05). Exploratory laparoscopy showed cloudy massive ascites and thickening of the mesentery. Pathological examination of the mesentery showed a large amount of eosinophils (median 177.5 [IQR 91-227]/HPF) and no malignancy. Based on these findings, it was suspected that the massive ascites due to eosinophilic peritonitis could be associated with colon cancer. Steroid administration resulted in immediate disappearance of the ascites, and laparoscopic left hemicolectomy was safely performed 6 weeks after steroid administration. CONCLUSION: This report presented a case of eosinophilic peritonitis that could be related to colon cancer. Exploratory laparoscopy was useful to detect the cause of ascites. The possibility that eosinophilic peritonitis was associated with colon cancer is discussed based on the histopathological findings.

We experienced two cases of shock secondary to colonic diverticular bleeding. Both patients showed signs of shock after each episode of melena; however, the bleeding site could not be initially identified because multiple diverticula were present and the bleeding spontaneously ceased during each examination. Therefore, we subsequently performed planned clipping and dynamic computed tomography scanning of the area surrounding the potential bleeding sites to look for signs of vascular leakage and to determine the clip location. The use of this method enabled us to successfully identify the bleeding site in both cases. Thus, this method can be useful in identifying the site of colonic diverticular bleeding that may cause shock.

A 64-year-old man presented with diarrhea, fever, and disturbance of consciousness; he was subsequently diagnosed with acute renal and hepatic disorder. Abdominal computed tomography identified a gas-forming liver abscess, and the patient underwent emergency drainage. However, his condition did not improve, and Clostridium perfringens was observed in his blood culture. Continuous perfusion drainage was performed by placing an additional drainage tube, which resulted in abscess shrinkage and improved the patient's general condition. Despite the low survival rate in patients with gas-forming liver abscesses caused by C. perfringens, therapy was successful in this patient.

A 33-year old woman was referred to our hospital because of gradually progressing abdominal pain and abdominal distension. A computed tomography demonstrated that distended cecum was located in the left retroperitoneal space. Barium enema revealed that the descending colon was positioned at the right side of the abdomen and transverse colon became severely tapered. Ceacal volvulus in addition to the internal herniation into the left retroperitoneal space was clinically diagnosed. The patient received an emergent operation. Operative findings showed that mesenterium commune, no fixation of the colon to the retroperitonium, and the internal herniation of terminal ileum to transverse colon into the sigmoid mesentery. Moreover, the cecal volvulus was diagnosed at the left retroperitoneal space. The mesenterium commune with internal herniation and cecal volvulus is extremely rare but one of important causes of acute abdomen.

We recently experienced an 87-yr-old man with gastric yolk sac tumor. Preoperative diagnosis was poorly differentiated adenocarcinoma in the cardia of stomach without apparent metastasis. A total gastrectomy was performed. The precise histological examination after surgery revealed the tumor was composed of pure gastric yolk sac tumor without adenocarcinomatous components. The surgical margin and the resected lymph nodes were histologically negative for the tumor and a curative resection was performed. Five months after the operation, enlargement of the intraabdominal lymph nodes occurred with elevation of serum alpha fetoprotein (AFP), and the patient died 2 mo later. Gastric yolk sac tumors are very rare, and only six cases of gastric yolk sac tumors have been previously reported in the literature. Five out of six cases are accompanied by components of adenocarcinoma, and our present case is the second report of pure gastric yolk sac tumor to the best of our knowledge.

We report a case of advanced schirrous gastric cancer with carcinomatous peritonitis. Chemotherapy with TS-1 was applied during the first 4 weeks, but the tumor did not respond to this therapy. Next, paclitaxel (TXL) was administered at a weekly dose of 90 mg/body/day for 3 weeks followed by a week interval of rest. Remarkable mass reduction of primary tumor was observed after 3 courses of treatment, and the symptom derived from primary tumor was relieved without significant side effects. The clinical course for schirrous gastric cancer with carcinomatous peritonitis is still miserable for patients, although many attempts have been made to improve its prognosis. A weekly paclitaxel regimen appears to be one of the promising treatment for schirrous gastric cancer.

A 22-year-old woman was admitted to this institution because of severe liver dysfunction that looked like acute hepatitis. Abdominal ultrasonography revealed a liver mass 20 mm in diameter that resembled the bull's-eye sign. Enhanced CT revealed a low-density mass. The mass was hypointense in T1-weighted MRI images and slightly hyperintense in T2-weighted MRI images. Needle biopsy of the liver under ultrasound guidance led to a diagnosis of solitary necrotic nodule of the liver. The tumor consisted of coagulation necrosis surrounded by fibrotic tissue. These pathologic features were consistent with the Imaging findings.
RESUMO
PURPOSE: We aimed to evaluate the efficacy and safety of gemcitabine/S-1 combination chemotherapy for the treatment of patients with advanced biliary tract cancer. METHODS: Patients with histologically or cytologically confirmed unresectable or recurrent biliary tract cancer were eligible for inclusion. The primary endpoint was overall survival. Gemcitabine was administered intravenously at a dose of 1,000 mg/m(2) over 30 min on days 1 and 8, and oral S-1 was administered daily at a dose of 60 mg/m(2) on days 1-14. This schedule was repeated every 3 weeks until disease progression or patient refusal. RESULTS: Twenty-five patients were enrolled between October 2007 and January 2009. Eleven patients (44%) had extrahepatic bile duct cancer, 5 (20%) had intrahepatic bile duct cancer, 8 had gallbladder cancer (32%), and 1 (4%) had ampulla of Vater cancer. The median overall survival time was 12.7 months (95% CI, 8.4-23.5 months), and the 1-year survival rate was 52.0% (95% CI, 31.2-69.2%). Of the 23 patients with evaluable target regions, seven patients experienced a partial response, and an overall response rate was 30.4%. The following grade 3-4 hematological toxicities occurred: neutropenia (56%), leukopenia (24%), anemia (8%) and thrombocytopenia (4%). In spite of the high incidence of grade 3-4 neutropenia, no patients developed febrile neutropenia in the present study. The major grade 3-4 non-hematological toxicities were fatigue (8%), anorexia (8%) and diarrhea (4%). CONCLUSIONS: Gemcitabine/S-1 combination chemotherapy offered a promising survival benefit with acceptable toxicity in patients with advanced biliary tract cancer.
