Impact of the VIO system in hepatic resection for patients with hepatocellular carcinoma.

PURPOSES: This study aimed to evaluate a novel surgical device combination [VIO system containing a bipolar clamp (BiClamp) and the monopolar soft-coagulation (SOFT COAG)] in hepatic resection for patients with hepatocellular carcinoma (HCC). METHODS: This study performed 124 hepatic resections for HCC and divided them into 2 groups: 60 patients (Conventional group) underwent liver parenchymal transection using Cavitron Ultrasonic Surgical Aspirator (CUSA) system and saline-coupled bipolar electrocautery for hemostasis; the BiClamp was used with the CUSA system for liver parenchymal transection and SOFT COAG was used with saline-coupled bipolar electrocautery for hemostasis in 64 patients (VIO group). RESULTS: The median blood loss in the VIO group was 345 mL, which was less than that in the Conventional group (median 548 mL, P = 0.0423). A multivariate logistic regression analysis showed that no use of the VIO system (P = 0.0172) was an independent predictor of intraoperative blood loss, respectively. In patients with liver cirrhosis, the VIO group included a significantly lower proportion of patients with liver cirrhosis that experienced more than 500 mL of intraoperative blood loss in comparison to those in the Conventional group (P = 0.0262). CONCLUSIONS: The VIO system was safe for hepatic resection and its use was associated with a significant decrease in intraoperative blood loss even in cirrhotic patients.

Long-term surviving patient with inferior vena cava tumor thrombus and extrahepatic metastasis after spontaneous ruptured hepatocellular carcinoma.

We present a case of long-term survival in a patient with inferior vena cava tumor thrombus (IVCTT) and extrahepatic metastasis after resection for spontaneous ruptured hepatocellular carcinoma (HCC). The patient was a 73-year-old Japanese man previously diagnosed with chronic hepatitis B. He was referred to our emergency room and diagnosed with spontaneous ruptured HCC. The patient was immediately treated with transcatheter arterial embolization, and we then performed second-stage hepatic resection 50 days later. Although des-gamma-carboxy prothrombin was reduced to a normal level after hepatectomy, it gradually increased and computed tomography showed a disseminated tumor in the diaphragm near S2 of the liver with IVCTT and right atrium tumor thrombus. Recurrent HCC was treated with monthly transcatheter arterial infusion chemotherapy (TAI) and conformal radiotherapy (RT) of 40 Gy. After TAI and RT procedures, the disseminated tumor and IVCTT completely disappeared. Four years after TAI and RT procedures, the tumors were well controlled with no local recurrence. About 6-7 years after spontaneous ruptured HCC, lung metastasis and spleen metastasis were detected and resected, respectively. The patient is still alive and doing well over 7 years after spontaneous ruptured HCC.

Long-term results of hepatic resection combined with intraoperative local ablation therapy for patients with multinodular hepatocellular carcinomas.

BACKGROUND: Recently, local ablation therapy has been widely used for treatment of small hepatocellular carcinoma (HCC). The present study assessed the outcome of hepatic resection combined with intraoperative local ablation therapy in patients with multinodular HCCs. METHODS: Forty-one patients with initial and multinodular HCCs underwent hepatic resection combined with intraoperative local ablation therapy. The mean maximum diameter of all tumors was 3.8 cm (range 2.1-16.0 cm), and the mean number of nodules was 3.2 (range 2-11). We evaluated the survival rates and assessed the prognostic factors associated with overall survival rates using Cox proportional hazard models. RESULTS: Intraoperative local ablation therapy was completed in all patients with no evidence of residual viable tumor on the first postoperative computed tomography (CT) scan. The 3-, 5- and 7-year overall survival rates were 84.3%, 61.2%, and 61.2%, respectively. Patients with preoperative des-gamma carboxyprothrombin (DCP) level >300 mAU/ml showed significantly worse overall survival than those with DCP level 300 mAU/ml was a significant prognostic factor of long-term overall survival.

Comparison of enteral nutrition with combined enteral and parenteral nutrition in post-pancreaticoduodenectomy patients: a pilot study.

BACKGROUND: Many clinical studies have demonstrated that early postoperative enteral nutrition (EN) improved the postroperative course. Post-pancreaticoduodenectomy (PD), patients tend to suffer from postoperative nausea, abdominal distention, and diarrhoea, causing difficulty in the introduction of EN. In this pilot study, we investigated the appropriate nutritional mode post-pancreatic surgery. METHODS: Between October 2006 and March 2007 2 postoperative nutritional methods were implemented in 17 patients in a prospective single-centere study. Eight patients received only enteral nutrition (EN group) and 9 patients received enteral nutrition combined with parenteral nutrition (EN + PN group). RESULTS: There were no differences in the patient characteristics and postoperative morbidity between the 2 groups. The rate of discontinuance of enteral feeding was significantly high in the EN group, and the duration of enteral feeding was significantly longer in the EN + PN group. The central venous line was retained for a significantly longer period in the EN + PN group, but there was no difference in the frequency of catheter-related infection between the 2 groups. CONCLUSION: EN combined with PN is more adequate for patients after pancreatic surgery.

Primary breast lymphoma in the right breast during treatment for left breast cancer.

BACKGROUND: Primary breast lymphoma is a rare condition, and distinguishing it from breast cancer is important because their treatments differ radically. Moreover, a recent report showed that mastectomy offered no benefit in the treatment of primary breast lymphoma. CASE PRESENTATION: A 59-year-old woman was treated with adjuvant chemotherapy and local radiation after surgery for left breast cancer. She presented with a rapidly growing mass in the right breast at 20 months after surgery. Mammography and computed tomography revealed a massive tumour. She was diagnosed with primary breast lymphoma by aspiration cytology, and surgery was performed. Histopathological and immunohistochemical findings confirmed a diffuse large B-cell type primary breast lymphoma. CONCLUSION: In this case, the lymphoma exhibited rapid growth despite chemotherapy for a malignancy in the contralateral breast. The patient had developed bronchiolitis obliterans organizing pneumonia due to radiation. Therefore, surgical treatment of the lymphoma was selected.

Mucin-hypersecreting bile duct neoplasm characterized by clinicopathological resemblance to intraductal papillary mucinous neoplasm (IPMN) of the pancreas.

BACKGROUND: Although intraductal papillary mucinous neoplasm (IPMN) of the pancreas is acceptable as a distinct disease entity, the concept of mucin-secreting biliary tumors has not been fully established. CASE PRESENTATION: We describe herein a case of mucin secreting biliary neoplasm. Imaging revealed a cystic lesion 2 cm in diameter at the left lateral segment of the liver. Duodenal endoscopy revealed mucin secretion through an enlarged papilla of Vater. On the cholangiogram, the cystic lesion communicated with bile duct, and large filling defects caused by mucin were observed in the dilated common bile duct. This lesion was diagnosed as a mucin-secreting bile duct tumor. Left and caudate lobectomy of the liver with extrahepatic bile duct resection and reconstruction was performed according to the possibility of the tumor's malignant behavior. Histological examination of the specimen revealed biliary cystic wall was covered by micropapillary neoplastic epithelium with mucin secretion lacking stromal invasion nor ovarian-like stroma. The patient has remained well with no evidence of recurrence for 38 months since her operation. CONCLUSION: It is only recently that the term "intraductal papillary mucinous neoplasm (IPMN)," which is accepted as a distinct disease entity of the pancreas, has begun to be used for mucin-secreting bile duct tumor. This case also seemed to be intraductal papillary neoplasm with prominent cystic dilatation of the bile duct.

Risk factors for and management of delayed intraperitoneal hemorrhage after pancreatic and biliary surgery.

BACKGROUND: Delayed intraperitoneal hemorrhage (DIH) is still an important cause of postoperative mortality in pancreatic and biliary surgery. METHODS: Sixty-nine patients who underwent pancreatic and biliary surgery with skeletonization for lymphadenectomy of the hepatoduodenal ligament between April 2002 and March 2005 were included in this study. Statistical analyses of the risk factors for DIH were performed using both univariate and multivariate modalities. RESULTS: DIH occurred in 4 patients (5.8%) within a median time of 15 days after surgery. Stepwise logistic regression analysis identified intra-abdominal abscess formation as the independent predictor of DIH. All 4 patients had a sentinel bleed before the onset of DIH. Three patients were treated by transarterial embolization and 1 patient was treated by surgical intervention. Three patients had liver abscess after hemostasis of DIH, but all 4 patients recovered and were discharged from the hospital. CONCLUSIONS: A computed tomography angiography should be performed on patients with intra-abdominal abscess formation and sentinel bleed after pancreatic and biliary surgery to check if a pseudoaneurysm has formed.

Gemcitabine combined with 5-fluorouracil and cisplatin (GFP) in patients with advanced biliary tree cancers: a pilot study.

BACKGROUND: Advanced biliary tree cancers have poor prognosis and chemotherapy has been shown to have little impact. To date, no standard chemotherapy regimens have been established. A pilot study to evaluate gemcitabine/5-Fluorouracil(5-FU)/cisplatin(CDDP) (GFP) chemotherapy in patients with advanced biliary tree cancers was performed. PATIENTS AND METHODS: Eight patients with advanced intrahepatic cholangiocarcinoma and gallbladder carcinoma with no prior chemotherapy were treated with a 4-week cycle GFP chemotherapy consisting of gemcitabine at 1000 mg/m2 on days 1, 8, and 15, and of 5-FU at 250 mg/patient and CDDP at 5 mg/patient on days 1 to 5, 8 to 12 and 22 to 26. RESULTS: Of these 8 patients, no complete responses (CR) were observed, but 3 patients (37.5%) demonstrated partial responses (PR) with an additional 3 patients (37.5%) having stable diseases (SD), as assessed by RECIST. Two patients with PR and 1 patient with SD were treated by curative operation after GFP chemotherapy and all of them survived with no recurrence. The median overall survival time was 23.5 months, and median time to progression was 14.5 months. Grade 3/4 side-effects, such as leukopenia, thrombocytepenia and anemia were found in 4 patients (50%), but no patients dropped out because of toxicity. CONCLUSION: This GFP chemotherapy has promising antitumor activity and is well tolerated in patients with advanced biliary tree cancers. This regimen warrants further evaluation in a phase II study including larger numbers of patients.

Hepatic resection without mortality at a community hospital.

The mortality of elective hepatic resections is now below 5%, and the improved result has been attributed partly to performance of such operations at high-volume specialized units. We retrospectively studied 60 consecutive elective hepatic resections performed during a 2-year period between April 1998 and March 2000 at a Red Cross community hospital. There was no hospital mortality and morbidity occurred in 20 patients (33.3%). High morbidity was associated with concomitant surgical procedures, especially ones with contamination of the operative field such as biliary and gastric surgery, but not with colonic procedures. Hepatic resections for primary and secondary malignancy, as well as benign diseases, can be performed without mortality at community hospitals, provided that adequate selection criteria is used and appropriate operative and postoperative management are available.
