RESUMO
Dissemination of pseudomyxoma peritonei into the thoracic cavity is rare and carries a poor prognosis. Optimal treatment has not been defined. In our institution, patients have received cytoreductive surgery with hyperthermic intrathoracic chemotherapy, which demonstrated a good prognosis. A 51-year-old woman was referred to our hospital with right intrathoracic dissemination of pseudomyxoma peritonei. We performed parietal and mediastinal pleurectomy and simple resection of all visible tumors on the diaphragm and visceral pleura, followed by hyperthermic intrathoracic chemotherapy with 20 mg mitomycin at 42°C to 43°C. The patient had no evidence of disease progression in the thoracic cavity 1 year after surgery.

OBJECTIVE: The role of single-trocar thoracoscopy for complicated parapneumonic effusion (CPE) and pleural empyema is not established as yet. The aim of this study was to report our experience and analyze the efficacy and safety of debridement by single-trocar thoracoscopy for the patients with CPE and multiloculated empyema. METHODS: We performed a retrospective study reviewing the medical records of the patients treated parapneumonic effusion and multiloculated empyema by single-trocar thoracoscopy under local anesthesia at our department from January 2000 to December 2012. RESULTS: A total 29 patients with CPE and multiloculated empyema were treated by single-trocar thoracoscopy. As the staging of pleural infection, class 5 and class 7 by Light classification were 21 and 8 patients, respectively. The onset of the symptom was on average 13.9 ± 11.7 days before the procedure. This procedure was successful in 23 of 29 patients (79.3%) without further operation under general anesthesia. Complication occurred in 1 case of 29 patients (3.4%). Six patients required subsequently the operation under general anesthesia, and one of the 6 patients died to multiple organ failure caused by sepsis. A microbiological diagnosis could be made in fifteen patients (51.7%). CONCLUSIONS: Debridement by single-trocar thoracoscopy can be an acceptable approach as the first-line procedure in patients with CPE and empyema. This procedure can provide not only appropriate and expeditious treatment but also information of pleural cavity to decide indication for thoracotomy under general anesthesia.

BACKGROUND: Green tea catechin, especially epigallocatechin gallate (EGCG), is a well-known scavenger of reactive oxygen species and it may also function as an antioxidant through modulation of transcriptional factors and enzyme activities. METHODS: Green tea extract (GTE®) which contained numerous EGCG was used. Wistar rats were performed 90 % hepatectomy and classified into 2 groups with (GTEHx, n = 25) or without GTE treatment (Hx, n = 25) and sacrificed at 1, 3, 7 and 14 days after operations. All rats had free access to drinking water supplemented with or without GTE from the 7th pre-operative day. Liver regeneration, hepatic inducible nitric oxide synthase (iNOS), anti-oxidative enzymes [superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSH-Px)] and inflammatory markers [cyclooxygenase-2 (COX-2), nuclear factor kappa B (NFκB), tumor necrosis factor-α (TNF-α)] were investigated. RESULTS: The liver weight to body weight ratio (p < 0.01), proliferating cell nuclear antigen labeling index (p < 0.05) and phosphorylated extracellular signal-regulated kinase 1/2 (p < 0.05) at day 1 in the GTEHx group significantly increased compared to the Hx group. Hepatic iNOS levels at day 1 significantly decreased (p < 0.01) in the GTEHx group. Hepatic SOD, CAT and GSH-Px levels at day 1 significantly increased (SOD: p < 0.01, CAT and GSH-Px: p < 0.05) in the GTEHx group. In contrast, COX-2, NFκB and TNF-α levels at day 1 significantly decreased (COX-2: p < 0.01, NFκB and TNF-α: p < 0.05) in the GTEHx group. CONCLUSIONS: GTE pretreatment stimulated liver regeneration and improved liver damage after massive hepatectomy through anti-oxidative and anti-inflammatory effects. Green tea catechin might have the potential to attenuate liver dysfunction in early stage after massive hepatectomy.

BACKGROUND/AIMS: After hepatic resection, delayed flatus and impaired bowel movement often cause problematic postoperative ileus. Kampo medicine, Dai-kenchu-to (DKT), is reported to have a various beneficial effects on bowel systems. The aim of this study was to prospectively evaluate effects of DKT after hepatic resection. METHODOLOGY: Thirty-two patients who underwent hepatic resection between July 2007 and August 2008 in Tokushima University Hospital were prospectively divided into DKT group (n=16) and control group (n=16). In DKT group, 2.5 g of DKT was administered orally three times a day from postoperative day (POD) 1. Blood was examined on POD 1, 3, 5 and 7. Postoperative first flatus, bowel movement and full recovery of oral intake, hospital stays and complications were checked. RESULTS: In DKT group, levels of c-reactive protein and beta-(1-3)-D-glucan on POD 3 were significantly decreased (p<0.05). Moreover, postoperative periods for the first flatus, bowel movement and the full recovery of oral intake were significantly shortened in DKT group (p<0.05). CONCLUSIONS: DKT suppressed inflammatory reaction, stimulated bowel movement and improved oral intake after hepatic resection, which may decrease serious morbidity after hepatic resection.
