A 60-year-old man with intrahepatic cholangiocarcinoma (ICC) underwent a left hepatectomy. Following the procedure, S-1 was administered during the period of five months. About two years after the hepatectomy, the patient underwent a hepatic resection again for remunant hepatic recurrences of ICC. Aggressive surgical resection may be the only method to assure a good outcome. An indication of resection for the hepatic recurrence of ICC will be examined in the future.

A 73-year-old woman who had underwent right lower lobectomy for adenocarcinoma of the lung( S10,pT1aN0M0, stage I A) 5 years before, visited our hospital with back pain. Whole body computed tomography (CT) revealed the enlargement of the abodominal lymph nodes surrounding the celiac artery,which was positive for fluorodeoxyglucose-positron emission tomography( FDG-PET). Open biopsy of the lymph node was performed and histopathological diagnosis was metastases of adenocarcinoma.Additional immunohistological examination showed positive findings for cytokeratin( CK) 7 and thyroid transcription factor( TTF)-1, but negative for CK20, suggesting the lesion to be metastases of lung cancer. Abdominal lymph node should be kept in mind in patients with lower lobe lung cancer.

A 48-year-old woman was hospitalized because of severe thrombocytopenia, leg edema, and fever. Intravenous immunoglobulin therapy was administered, but no efficacy was obtained. Her bone marrow was dry-tap, and fibrosis was found in the biopsy specimens. A positron emission tomographic study showed FDG-avid lymphadenopathy and hepatomegaly. Biopsy specimens of axillary lymph nodes showed Castleman's disease-like findings. Since she then developed severe proteinuria and massive pleural effusion, steroid therapy was started, providing temporary relief of symptoms other than the thrombocytopenia. However, rapid worsening of her general condition prompted us to attempt rituximab as salvage therapy. The pleural effusion, edema, and proteinuria disappeared soon after starting rituximab administration. Platelet counts also normalized and fibrosis of the bone marrow showed amelioration. Recently, a variant of multicentric Castleman's disease, termed the TAFRO syndrome, has been proposed, and our patient's features fit the diagnosis of this syndrome. Rituximab might be considered as a therapeutic option in such cases.

Postoperative antimicrobial therapy is generally administered as standard prophylaxis against postoperative infection, despite a lack of sufficient evidence for its usefulness. This study was a phase II study to evaluate the necessity of postoperative antibiotic prophylaxis in patients undergoing a colectomy. Patients received 1 g cefmetazole or flomoxef immediately after anesthetic induction, every 3 h during surgery, and then later once again on the next day. They were randomly assigned to receive either cefmetazole or flomoxef. Ninety-one patients were enrolled in the study. A surgical site infection (SSI) occurred in 7.7% (7/91) of patients. All cases were superficial incisional infections. When comparing the two drugs, SSI occurred in 8.3% (4/48) of patients treated with cefmetazole and in 7.0% (3/43) treated with flomoxef, showing no significant difference (P > 0.99). Antimicrobial prophylaxis was well tolerated when used on the day of a colectomy and once again on the next day.

Purpose: To evaluate the technical success and clinical effectiveness of percutaneous transcholecystic placement of self-expanding metallic stents for the treatment of malignant obstructions of the common bile duct. Materials and Methods: Fifteen patients with malignant obstruction at the lower level of the common bile duct not amenable to surgery were retrospectively reviewed in this study. In all patients, conventional biliary drainage via transhepatic peripheral duct access or endoscopic retrograde biliary drainage (ERBD) were technically difficult or deemed so at imaging evaluation. The causes of obstruction were cholangiocarcinoma (n = 7), pancreatic carcinoma (n = 6), and metastatic lymphadenopathy from gastric carcinoma in the hepatoduodenal ligament (n = 2). Following percutaneous cholecystostomy, a 5-F catheter was inserted into the common bile duct, duodenum, or the anastomosed jejunum through the cystic duct and the malignant obstruction and metallic stents were placed. The technical success was defined as the removal of the drainage tube after the stent placement for the obstruction. The mean follow-up period was 25.4 months. Results: Sixteen stents were placed in 15 patients. Technical success was achieved in all patients (100%) without major complications. Minor complications included controllable pain or self-limited hemobilia in six of the 15 patients (40%). Lower bilirubin levels compared with those before the procedure were achieved in 14 of the 15 patients (93%). Conclusions: Percutaneous transcholecystic placement of metallic stents is a feasible and effective method to manage malignant obstruction at the lower level of the common bile duct not amenable to surgery when conventional biliary drainage via transhepatic peripheral duct access or ERBD were technically difficult or deemed so at imaging evaluation. © 2010 SIR.
