ABSTRACT
We reported a case of hepatocellular carcinoma (HCC) with needle tract implantation of the right thoracic wall, which were strongly suspected to have been caused by percutaneous needle biopsy performed at the former hospital to diagnose HCC in September 2001. He visited our hospital at his age of 68 and underwent transcatheter arterial embolization in February 2002. In November 2007, a right 9th intercostal tumor measuring 20 x 15 mm was found on his computed tomography (CT) scan. He underwent resection of the right thoracic wall tumor in January 2008. Pathological diagnosis of the tumor was well differentiated HCC. Twenty one months after surgery, he remains alive without recurrence.

A 29-year-old man was referred to our hospital with fulminant hepatic failure (FHF) and stage III hepatic coma (somnolence and confusion). Living donor liver transplantation (LDLT) was planned for 2 days after admission to our hospital. However, on the day after admission, he lapsed into stage IV hepatic coma: no right reflexes and no response to pain stimuli. Emergency cranial computed tomography revealed a subarachnoid hemorrhage (SAH), but no aneurysm was seen on magnetic resonance angiography. We speculated that the cause of the SAH may have been bleeding of intracranial veins secondary to coagulopathy and overextension of a vein due to brain edema. We considered that only LDLT could improve the coagulopathy and brain edema. The patient recovered consciousness on postoperative day (POD) 2 and was finally discharged from the hospital without neurological deficit on POD 85. This case suggested that SAH is not a prohibiting factor for LDLT in an FHF patient if the cause of the SAH is venous bleeding.

Invasive pulmonary aspergillosis (IPA) occurs in 1.5 to 10% of liver transplant recipients. Of the fungal infections, IPA is the most difficult to treat and the most frequently life-threatening. However, the best treatment strategy remains controversial. The patient was a 53-year-old woman who underwent living donor liver transplantation (LDLT) because of subacute fulminant hepatic failure due to autoimmune hepatitis. Aspergillus fumigatus was detected in the sputum taken intraoperatively by bronchial suction. A computed tomogram of the lung 7 days after LDLT showed fungal balls in the left lung. IPA was diagnosed. Since the patient suffered from pulmonary edema postoperatively and fungal balls occupied a greater part of the left lung, conservative therapy using micafungin, amphotericin B, and itraconazole was first selected. However, the fungus balls did not completely disappear. Moreover, brain abscess probably resulting from IPA dissemination was detected. Lung resection was performed as reduction surgery, and salvage treatment using voriconazole was done for a brain abscess. Septate hyphae of Aspergillus fumigatus were identified in the lung specimen. We concluded that for patients with IPA after LDLT, pulmonary resection should be done as soon as possible before deterioration of IPA and complication due to acute cellular rejection.

In Japan and Korea, where availability of deceased donor organs for solid organ transplantation remains rare, living donor liver transplantation (LDLT) using a posterior section graft (PSG; segments VI+VII, according to Couinaud's Nomenclature for liver segmentation) has now been accepted as a standard procedure that balances donor risk and patient benefits for cases in which right hemi-liver donation is too risky, because of marked volume imbalances between right and left hemi-livers. Compared with other types of grafts, however, the procedure requires detailed knowledge concerning hepatic vascular anatomy and meticulous manipulation during donation surgery. We present herein a case of delayed bile leakage from a remaining part of segment 8 in a PSG, which was considered to be a complication peculiar to LDLT using a PSG.

This study sought to determine whether a prognostic score is a useful indicator of donor safety using 13 consecutive donors enrolled for liver transplantation. The donor operations were right hepatic lobectomies (n = 10) and left hepatic lobectomies (n = 3). The postoperative maximal level of serum total bilirubin was used to assess the magnitude of surgical stress. Variables such as donor age, percentage of liver resection (PLR), indocyanine green 15-minute retention rate (ICGR15), operative blood loss, operation time, prognostic score and graft weight were evaluated as predictors of the magnitude of surgical stress. The PLR and prognostic score (PS) were calculated according to the following formulae: PLR (%) = 100*Graft weight (g)/standard liver volume of the donor (mL); PS = -84.6 + 0.933*PLR (%) +1.11*ICGR15 (%) +0.999*age (years); Standard liver volume (mL) = 706.2*body surface area (m2) + 2.39. No serious complications occurred after the donor operations. Maximal bilirubin ranged from 1.9 to 10.9 mg/dL. There were no mortalities, although there were two morbidities, bile leakage and prolonged liver dysfunction. Postoperative hyperbilirubinemia was observed in two donors and in one Gilbert's syndrome donor. Linear regression analysis of each variable indicated poor correlations between those variables and maximal bilirubin. However, close correlations were seen between maximal bilirubin and both donor age and PS except for the three patients who showed postoperative hyperbilirubinemia. In these uneventful donors, statistical formulae were obtained as follows: maximal bilirubin (PMB) = 0.271 + 0.056*donor age (correlation coefficient 0.612, P < .008), PMB = 1.541 + 0.059*PS (correlation coefficient 0.597, P < .009). In conclusion, PS is useful to predict maximal bilirubin and to ensure donor safety.

BACKGROUND: To overcome problems arising from a graft of insufficient size, right liver grafts have been used extensively for adult-to-adult living donor liver transplantation (LDLT). However, there are reports of severe congestion in the anterior segment of the graft after transplantation. CASE REPORTS: Right liver transplantation without the middle hepatic vein was performed in six cases. In the second and third cases, the inferior right hepatic vein was reconstructed because it was thick (whereas the middle hepatic vein was not). Abdominal CT revealed congestive infarction of the anterior segment in the second case and of the posterior segment in the third. It was suspected that the former resulted from the lack of an middle hepatic vein, and the latter from obstruction of the reconstructed inferior right hepatic vein. Both patients died without improvement in liver function. Accordingly, in the fifth case, the middle hepatic vein was reconstructed. The postoperative course of this case was uneventful. Doppler ultrasonography showed profuse blood flow in the interposition graft. In the sixth case, the middle hepatic vein was not reconstructed because of technical difficulties. Although abdominal CT showed a congestive area in the anterior segment, the patient recovered uneventfully, probably because the volume of functional graft was sufficient even without the congestive area. CONCLUSION: When the color becomes dark in more than half of the surface of the anterior segment following clamping of middle hepatic vein tributaries and the hepatic artery, the middle hepatic vein should be reconstructed. When the diameter of the inferior right hepatic vein is more than 5 mm, its reconstruction is also recommended.

AIM: This study was conducted to clarify the management of perioperative infectious complications after adult living donor liver transplantation (LDLT). PATIENTS AND METHODS: Fourteen adult LDLT patients were enrolled in this study. We examined the occurrence of infectious complications in these cases and the relationships of infectious complications to UNOS status and MELD score. Surveillance culture and immunoserologic analyses were performed. From the results of these analyses, we made a diagram of infection surveillance using a matrix of time and sampling site. Using the diagram, we chose sensitive antibiotics as soon as possible. RESULTS: The infection site and its pathogen were able to be detected in four (28.5%) patients, all of whom had MRSA infections, together with lung aspergillosis in one case, pseudomonas pneumonia in another, and both in another. Two patients died of lung aspergillosis. Bacteria detected in the airway tended to spread to other sites during the postoperative period. In all four patients in whom infectious diseases were detected, and in a fifth patient in whom the site of infection was not known, the UNOS status was 1. The MELD score was calculated in eight patients, six of whom had high MELD scores (>20). CONCLUSION: Most cases were manageable by choosing and changing antibiotics and antifungal drugs according to the results of surveillance cultures twice a week. However, aspergillosis had an extremely poor prognosis. Patients with a high MELD score or low UNOS status, or both, showed poor prognosis; and in them, multiple drug resistance bacteria caused severe perioperative infectious complications.

This study assessed the usefulness of artificial liver support (ALS) for pretransplant patients with fulminant hepatic failure (FHF). Five patients (age 14 to 52 years, 3 men and 2 women) with FHF who were being prepared for living donor liver transplantation (LDLTx) were enrolled in this study. ALS included plasma exchange, using 40 to 50 units of fresh frozen plasma per session, and high-flow hemodiafiltration, using a high-performance polysulfone membrane. Variables such as circulatory and respiratory function, coma grade, and neurologic disorders were evaluated. Although systolic and diastolic blood pressures showed no statistical differences between pre-ALS and post-ALS, the difference in heart rates was statistically significant. After ALS initiation in the pre-LDLTx period, one of the three patients who needed mechanical ventilation was weaned from it. After LDLTx, all patients recovered neurologically; no neurologic disorder was observed. These results suggested that ALS could predict neurologic status after LDLTx. The difference in coma grades also achieved statistical significance. Our study indicates that short-term ALS is useful for improving circulatory and respiratory function prior to liver transplantation, as well as for predicting posttransplantation neurologic status. Although some patients recover by ALS alone, the survival rate of ALS-only patients is less than 50%. ALS prolongs intensive treatment, thus increasing both the risk of infection and the medical costs. Further investigation to determine a precise marker for liver regeneration will be needed to establish a consensus on the indications for long-term ALS. We conclude that ALS is useful to improve circulatory and respiratory functions among pretransplant patients, and to predict neurologic status after LDLTx.

The right margin of the caudate lobe is obscure. Therefore, a part of the caudate lobe (a part of the right side of the paracaval portion) seems almost always to remain with the right lobe graft during the standard harvesting procedure. We reviewed the intraoperative findings and the postoperative courses of donors and recipients of 11 consecutive living donor liver transplantations using right lobe grafts. Further, we used computed tomography during the postoperative course to investigate whether the remaining caudate lobe was present in the right lobe graft and whether it produced serious complications. Four recipients displayed an intraoperative bile leak from a remaining part of the caudate lobe after the completion of biliary reconstruction. With the exception of one case who developed repeated bile leakage from the same origin which eventually healed during a long-term postoperative course, Most recipients showed no postoperative biliary complications. Although a remaining caudate lobe was detected on postoperative computed tomography in all recipients, it produced no serious complications. In conclusion, a part of the right side of the paracaval portion of the caudate lobe almost always remains with a right lobe graft during the standard harvesting procedure. However, the implications of this phenomenon seem to be benign.

More than 10 years have passed since hepatic artery resection was first performed for the treatment of biliary tract cancer. The safety of this procedure has been established with the introduction of the microsurgery technique. However, the benefits of and indications for this treatment have not yet been clarified. Twenty-three patients underwent vascular resection (portal vein in 7, portal vein + hepatic artery in 9, hepatic artery in 7) among 114 resected patients with biliary tract cancer in our institution. The right hepatic artery was reconstructed by end-to-end anastomosis in most cases. The curative resection rate was 88.9% in hilar bile duct cancer. However, it was less than 50% in other carcinomas. Cumulative 5-year survival rates of vascular resection patients with hilar bile duct cancer, lower bile duct cancer, gallbladder cancer, and cholangiocarcinoma were 14.8%, 25%, 0%, and 0%, respectively. On the other hand, the rates were 38.9%, 0%, 0%, and 0%, in the stage III + IV patients who did not undergo vascular resection. The longest survival period among patients with hilar bile duct cancer and lower bile duct cancer was 85 months and 65 months, respectively, whereas it was 15 months in gallbladder cancer and 20 months in cholangiocarcinoma patients. No hilar bile duct cancer patient who survived for more than 3 years had lymph node metastasis. The longest surviving cholangiocarcinoma patient has received adjuvant chemotherapy consisting of 5-fluorouracil and cisplatin. It is concluded that patients with hilar bile duct cancer are good candidates for vascular resection. Adjuvant chemotherapy should be administered to gallbladder cancer and cholangiocarcinoma patients, because vascular resection alone does not result in prolongation of life in these patients.

BACKGROUND: We report a case of severe polycystic liver disease (PLD) with jaundice in a 57-year-old woman who underwent successful left trisegmentectomy. METHOD: She was admitted for the first time in February 1992 to our hospital with a 7-year history of PLD, and became jaundiced in June 1995. Because normal liver parenchyma was confirmed mainly to the posterior segment, left trisegmentectomy was performed. RESULTS: No postoperative complication occurred. The serum bilirubin level decreased promptly after the operation, but postoperative endoscopic retrograde cholangiography showed that the root of the posterior hepatic duct remained thin. Thus, the elimination of jaundice was presumed to have been caused by a decrease of intra-abdominal and peripheral biliary pressure, since a large volume of tissue had been removed from the peritoneal cavity. She has since remained well without any symptoms. CONCLUSION: This procedure is useful for severe PLD, because it can be performed safely and the symptoms disappear dramatically. However, further follow-up is needed to determine the long-term effects of this procedure, because the remaining liver has shown some increase in size.

The aim of this study was to analyze the patency of expandable metallic stents in malignant biliary obstruction and to evaluate the efficacy of adjuvant therapy accompanied by biliary stenting. We analyzed 29 patients in whom bile duct stenting was performed for malignant biliary obstruction. Their types of disease were: hilar ductal carcinoma (n = 8), gallbladder carcinoma (n = 11), and pancreatic carcinoma (n = 10). Initially, 46 expandable metallic stents were placed in 29 patients. In 23 of the 29 patients, adjuvant therapy was administered. Seventeen patients underwent radiotherapy, and 16 patients received various systemic chemotherapies. In principle, hyperthermia was performed twice a week, simultaneously with radiotherapy. Patient survival and the probability of stent patency were calculated using actuarial life table analysis. There was no significant difference in stent patency among the patients according to type of disease. Hyperthermia did not influence the stent patency rate. The median stent patency time was significantly greater in the chemo-radiation group than in the no-adjuvant therapy group: 182 days versus 68 days, respectively (P = 0.017). Moreover, a significant increase was seen in the median survival time in the chemo-radiation group: 261 days versus 109 days (P = 0.0337). Complications occurred in 9 patients (31.0%). Stent occlusion occurred in 6 patients (20.7%), with all of these patients managed successfully using a transhepatically placed new expandable metallic stent, employing the stent-in-stent method. Stent migration occurred in 2 patients after radiotherapy. Adjuvant therapies such as radiotherapy and systemic chemotherapy, in combination with stent insertion, resulted in an increase in the patency period of expandable metallic stents and in increased patient survival time.

BACKGROUND/AIMS: Indications for hepatic vein reconstruction for preserving remnant liver function after hepatectomy were assessed using the clamping test and the findings of preoperative 3D-CT (3-dimensional computed tomography). METHODOLOGY: Fifteen patients who underwent hepatectomy for malignant tumors in segment VII or VIII, or both, were examined with preoperative 3D-CT and an intraoperative clamping test. RESULTS: On the basis of changes in right hepatic venous pressure during clamping, we classified all patients into 3 types: the persistent elevation type (P-type, 8 patients), the no elevation type (N-type, 3 patients) and the transitory elevation type (T-type, 4 patients). Hepatic venous hemoglobin oxygen saturation (ShvO2) decreased significantly in the P type but hardly changed in the T and N types during the clamping test. Both the inferior right hepatic vein (IRV6) and the tributary of the middle hepatic vein draining segment V (MV5) were detected by preoperative 3D-CT in the T and N types. CONCLUSIONS: Assessments of hepatic vein branch distribution using preoperative 3D-CT served to predict the results of the hepatic vein clamping test. The results of preoperative 3D-CT were useful as indications for hepatic vein reconstruction.

PURPOSE: Hepatoduodenal ligament invasion (HLI) is an inhibiting factor for the curative resection of advanced gallbladder cancer. The aim of this study was to clarify the indications for surgical resection in patients with advanced gallbladder cancer with and without HLI by analyzing outcomes. METHODS: The subjects were 58 patients with advanced gallbladder cancer who underwent aggressive resection, and 20 nonresected patients diagnosed as haring HLI. The presence of stromal cancerous infiltration at six sites in the hepatoduodenal ligament was investigated. The extent of cancer spread was classified into two grades by the number of sites where cancer cells detected: low grade, one or two invasion sites; high grade, three or more sites. RESULTS: Pancreatoduodenectomy, vascular reconstruction, and extensive hepatectomy were frequently performed in the patients with HLI. The cumulative 5-year-survival rate of the HLI patients was 10.9%, significantly worse than that of the resected patients without HLI (46.6%; P < 0.01). Patients with paraaortic lymph node metastasis died within 1 year. The cumulative 5-year-survival rate after curative resection was 38.1%, significantly better than that after noncurative resection (0%; P < 0.05). The survival was significantly worse in patients with high-grade invasion than in these with low-grade invasion (P < 0.05), being equivalent to that in the nonresection patients. Of four factors, operative curability, hepatic lobectomy, HLI grade, and paraaortic lymph node metastasis, the HLI grade and hepatic lobectomy were considered to be significant prognostic factors by Cox's multivariate analysis (backward stepwise method). CONCLUSIONS: Aggressive surgical resection for curative purposes should be limited to patients with low-grade HLI and metastasis-negative paraaortic lymph nodes.

Hepatocellular carcinoma (HCC) with retrohepatic intracaval extensions are difficult to treat. HCC may sometimes extend into the inferior vena cava (IVC) through two routes: via the right hepatic vein and via the inferior right hepatic vein. In such cases, in which tumor emboli are located both above and below the confluence of the hepatic vein with the IVC, we first remove the upper embolus during THVE, and then remove the lower one while the IVC is clamped obliquely in order to preserve the residual liver circulation.
