Gallbladder carcinoma in the era of laparoscopic cholecystectomy.

OBJECTIVE: To assess the usefulness of laparoscopic cholecystectomy for unsuspected and suspected gallbladder carcinoma. DESIGN: Retrospective review with a mean follow-up of 27 months, ranging from 1 to 47 months. SETTING: University hospital and 8 affiliated hospitals. PATIENTS: Of 2616 laparoscopic cholecystectomies performed over 4 years, 24 gallbladder carcinomas were treated by laparoscopic cholecystectomy and retrospectively reviewed. RESULTS: The clinical course depended on the histopathologic depth of invasion of gallbladder carcinoma. All 6 cases of pathologic tumor (pT) stage in situ (pTis) gallbladder carcinoma and 2 cases of pT1 gallbladder carcinoma showed no invasion to the lymphatic, venous, or perineural spaces, and these 8 patients were all doing well from 2 to 19 months (mean, 11 months) after laparoscopic cholecystectomy. Sixteen cases of pT2 or pT3 gallbladder carcinoma invaded the subserosal layer or the liver, and 5 of the 16 patients were dead of liver dysfunction, abdominal wound recurrence, or liver metastasis 5 days and 7, 12, 15, and 18 months after operation, although additional resection of the liver bed with lymph node dissection was performed after laparoscopic cholecystectomy in 4 of these 5 patients. Abdominal wall recurrence in the absence of distant metastasis was present in 3 (19%) of the 16 patients with pT2 or pT3 gallbladder carcinoma due to inoculation of cancer cells in the abdominal stab wounds where the gallbladder or laparoscope was removed. CONCLUSIONS: Gallbladder carcinoma at the pTis or pT1 stage removed laparoscopically needs no other treatment. We recommend that the gallbladder be removed by vinyl bag and port sites be excised or washed with normal saline to prevent port site recurrence in patients with laparoscopic cholecystectomy for pT2 or pT3 carcinoma.

Protein-calorie malnutrition in liver cirrhosis.

The purpose of this article is to present detailed data on the nutritional assessment in cirrhotic patients. The exact frequency and types of malnutrition, its associations with the aetiology of liver disease, liver dysfunction and clinical staging in liver cirrhosis are unknown. A new classification system is presented which may help to suggest some interventional guidelines. Physical (anthropometry, 24-h urinary creatinine excretion, bioelectrical impedance analysis (BIA), total body potassium counting, ultrasound examination) and metabolic (indirect calorimetry) assessment of nutritional status was therefore performed in 123 patients with liver cirrhosis, who were considered as potential candidates for liver transplantation. Data were related to the clinical, biochemical, histological and prognostic data of liver disease. Of our patients 65% showed some signs of protein-calorie malnutrition as indicated by low body cell mass, reduced serum albumin concentrations or abnormal skinfold thickness. Of these 34% were considered as "kwashiorkor-like" (normal body composition, serum albumin less than 35 g/l), and 18% were "marastic" (reduced body weight, body cell mass, and fat mass). However, 49% of the malnourished group had reduced body cell mass in association with increased fat mass and frequently presented with a normal body weight ("mixed" or "obese" type). Protein-calorie malnutrition did not correlate with the aetiology of the disease and biochemical parameters of liver function. Malnutrition was observed at all clinical stages but was more frequently seen at advanced stages. We conclude that malnutrition associated with liver cirrhosis is not a clear phenomenon. Its clinical presentation is heterogenous and not reflected by the histological or biochemical parameters of liver disease.(ABSTRACT TRUNCATED AT 250 WORDS)

Chronic interstitial nephritis in Whipple's disease.

Report is given on a 68-year-old man who suffered primarily from progressive weight loss and repeated episodes of fever and arthralgia. Later, liver dysfunction and renal insufficiency developed. Liver and kidney biopsies disclosed granulomatous hepatitis and nephritis. Because of the morphologic and clinical findings, the diagnosis of Boeck's disease was made. Shortly before death, diarrhea developed. Autopsy revealed a massive systemic involvement in Whipple's disease proven by light and electron microscopy and immunofluorescence. Tuberculoid and epitheloid cell granulomas and isolated giant cells were found in addition to the biopsy findings in skeleton muscles, the small intestine, lymphnodes and bronchi. At autopsy, the kidney showed chronic interstitial nephritis. The literature of kidney involvement in Whipple's disease is reviewed. This is the first case with granulomatous interstitial nephritis and chronic renal insufficiency in an inadequately treated Whipple's disease.

Drug-induced mononucleosis-like hepatic injury in a patient with systemic lupus erythematosus.

A case of systemic lupus erythematosus (SLE) with mononucleosis-like hepatic injury was described. An emergent cesarean section was performed in a 25 yr-old house wife at 34 weeks gestation, followed by administration of several antibiotics. After the surgery she complained of high fever, hepatomegaly and dull right hypochondralgia, and mild liver dysfunction was also found. The liver biopsy showed prominent mononuclear cell infiltration in the sinusoids with minimum hepatocellular necrosis and mild triaditis, resembling hepatic lesion in infectious mononucleosis (mononucleosis-like injury). There were no clinical and serological features suggestive of infectious mononucleosis. This hepatic lesion was thought to be a manifestation of allergic reaction to drugs to which the lymphocyte stimulation test was found to be positive. Immunological abnormalities inherent in SLE might be related to occurrence of such allergic drug reaction.

Clinical observation of the effect of Xuesaitong soft capsule on post-hepatitis fibrosis.

OBJECTIVE: To study the effect of Xuesaitong soft capsule (XST) on liver fibrosis criteria in patients with post-hepatitis fibrosis. METHODS: Sixty-four patients with such fibrosis were randomly divided into the treated group and control group. They were treated with XST and Dahuang Zhechong pill (NFDA1) for 3 months respectively. Their liver fibrosis criteria were examined before and after treatment. RESULTS: The levels of serum procollagen III, hyaluronic acid, collagen IV, laminin in the two groups were significantly lower (P < 0.01) than those before treatment. The differences between the two groups were insignificant (P > 0.05). CONCLUSION: XST could recover liver dysfunction and had anti-liver fibrosis function.

Jaundice in critical illness: promoting factors of a concealed reality.

OBJECTIVE: In critical illness, liver dysfunction (LD) is associated with a poor outcome independently of other organ dysfunctions. Since strategies to support liver function are not available, a timely and accurate identification of factors promoting LD may lead to prevention or attenuation of its consequences. The aim of this study was to assess risk factors for LD in critically ill patients. DESIGN: Prospective, observational study. SETTING: A multidisciplinary intensive care unit (ICU) of a university hospital. PATIENTS: All patients consecutively admitted over a 6-month period. INTERVENTION: None. MEASUREMENTS AND RESULTS: LD was defined as serum bilirubin levels >or=2 mg/dl and lasting for at least 48 h. Out of 283 patients, 141 matched inclusion criteria. Forty-four patients (31.2%) showed LD (LD group), while 97 (68.8%) were included in control group (C group). A binomial analysis showed that LD occurrence was associated with moderate (odds ratio [OR] 3.11; p=0.04) and severe shock (OR 3.46; p= 0.05), sepsis (OR 3.03; p=0.04), PEEP ventilation (OR 4.25; p=0.006), major surgery (OR 4.03; p=0.03), and gram-negative infections (OR 3.94; p=0.002). In stepwise multivariate analysis, the single independent predictive factors of LD resulted in severe shock (p=0.002), sepsis (p=0.03), PEEP ventilation (p=0.04), and major surgery (p=0.05). CONCLUSIONS: In critically ill patients jaundice is common, and severe shock states, sepsis, mechanical ventilation with PEEP and major surgery are critical risk factors for its onset. Since there is no specific treatment, prompt resuscitation, treatment of sepsis and meticulous supportive care will likely reduce its incidence and severity.

The role of medical treatment of distal type aortic dissection.

We analyzed the short-term and long-term outcome of 42 patients with distal type aortic dissection. Twenty-eight patients underwent intensive medical therapy within two weeks after the onset of pain (acute dissection). The remaining 14 patients had chronic dissection. The goals of medical treatment were to control blood pressure and to attain a negative C-reactive protein test result. Hospital survival rate in the patients with acute dissection was 96% (27/28). In-hospital complications included changes in mental status, renal dysfunction, bradycardia, orthostatic hypotension, and liver dysfunction, all of which were managed medically. Three of these patients underwent surgical therapy in the chronic phase and were discharged uneventfully. Fifteen (62.5%) of the 24 medically treated patients were discharged with negative C-reactive protein tests. Spontaneous resolution of a dissection was demonstrated by radiological examinations in 8 cases. Five-year survival rates in 24 medically treated patients was 93%. Hospital survival rate in the patients with chronic dissection was 100% (14/14). The rigorous control of blood pressure in the acute phase, and subsequent meticulous evaluation of the dissection by radiological tests and C-reactive protein test provides acceptable short-term and long-term outcomes of patients with acute distal dissection without the need for emergency surgical intervention.

Ximelagatran: a clinical perspective.

Ximelagatran is a novel oral anticoagulant belonging to a class of drugs known as direct thrombin inhibitors. Numerous recent large-scale, randomised controlled clinical trials have given the drug a large clinical platform. These include data on the thromboprophylaxis of venous thromboembolism following major orthopaedic surgery and knee arthroscopy, as well as in the treatment of deep vein thrombosis and prevention of stroke with nonvalvular atrial fibrillation. One phase II study has also shown the efficacy and safety of ximelagatran in secondary prevention post-myocardial infarction. Unfortunately, approximately 6% of patients develop usually self-limiting derangement of liver dysfunction, and frequent monitoring of liver function is likely to be recommended for the first 6 months of treatment. Unlike the vitamin K antagonists, ximelagatran has a wide therapeutic interval with few food, alcohol or drug interactions, and it does not require anticoagulant monitoring. The aim of this overview is to review the clinical trials pertaining to this new drug, which is the first new oral anticoagulant for over 60 years, and one that is likely to influence our management of thrombosis-related disorders.

Results of 132 hepatectomies for living donor liver transplantation: report of one death.

AIMS: Liver transplant is the primary therapy for patients with end-stage liver disease. Its high success rates have lead to a broadening of the indications for liver transplantation, resulting in an increasing shortage of donors. Living donor liver transplantation has become an option to overcome waiting list mortality. We describe our experience with hepatectomy for living donor liver transplantation and report a case of death. METHODS: Patients (n = 132) underwent hepatectomy for living donor liver transplantation from June 2000 through June 2004. A 4-phase preoperative evaluation was performed on all patients, whose ages ranged from 13 to 54 years (mean = 29.7 +/- 8.1 years). Of the 132 patients, 76 patients (57.5%) underwent left lateral segmentectomy, 33 patients (25%) underwent left lobectomy, and 23 patients (16%) underwent right hepatectomy. In 2 other patients (1.5%), a monosegment (segment II) was obtained after left lateral segmentectomy. RESULTS: Twenty patients (15%) experienced a complication, the most common being incisional hernia, pneumonia, and biliary fistulae. On the seventh postoperative day, 1 patient developed a fatal cerebral hemorrhage while recovering from mild liver dysfunction. CONCLUSIONS: Although living donor liver transplantation is generally safe, serious and fatal complications may occur.

Peritoneoscopic findings and liver function in chronic liver disease.

In 100 cases with chronic liver disease, peritoneoscopy and liver biopsy were performed, and the association between peritoneoscopic findings and liver function was studied. With respect to liver function, a series of tests which seem to indicate residual liver function were selected as follows; dye excretion, serum levels of albumin and cholinesterase, and subfractions of serum proteins. In evaluating the periotoneoscopic view, new criteria for the classification of liver surface findings are proposed. All cases were divided into 5 types in accordance with these criteria. Analysis of the correlation between peritoneoscopic findings and liver function showed that the degree of liver dysfunction was clearly indicated by liver surface alterations. As a result, the residual liver function may be determined quite well by using this classification.

Histologic activity of childhood chronic hepatitis B related to viremia levels, genotypes, mutations, and epidemiologic factors.

BACKGROUND: Despite high viral load, children with chronic hepatitis B virus (HBV) infection may lack significant biochemical signs of liver dysfunction. Failure to develop abnormal liver chemistriesis is probably due to immunologic hyporeactivity. Despite the absence of biochemical abnormalities in these patients, there is still a risk for long-term complications. The pathogenic importance of viral load and genetic variability is less well studied in children than in adults. METHODS: We evaluated viremia levels, genotypes, and mutations related to histologic evidence of liver damage in 71 HBV carriers, aged 2 to 18 years, all of non-Swedish origin. RESULTS: None of the of 22 children who were hepatitis B e antigen (HBeAg) negative had severe liver disease or had HBV DNA levels greater than 10 copies/mL (mean 10 ); 3 (14%) of them had increased alanine aminotransferase (ALT). The 49 HBeAg-positive children had a mean HBV DNA level of 10 copies/mL, and increased ALT was seen in 28 (55%). Core promoter mutations (at nt 1764) or precore mutations (at codon 1, 2, or 28) were rare; they were seen in four and one HBeAg-positive children, and in four and nine HBeAg-negative children, respectively, without association to liver damage. C-1858 was associated with more liver inflammation. Genotype did not significantly influence liver damage. Children with horizontal transmission had a faster rate of seroconversion and more inflammation of the liver. CONCLUSIONS: Severe HBeAg-negative hepatitis with high HBV DNA levels and mutations in the core promoter or precore regions seems to be less common in children than in adults. C-1858 strains may be more pathogenic, but this requires further study. Epidemiologic factors influence the course of infection.

Life-threatening veno-occlusive disease after living-related liver transplantation.

Veno-occlusive disease (VOD) can develop in association with the administration of cytotoxic chemotherapeutic agents and irradiation. In solid-organ transplant settings, azathioprine has been implicated as a predisposing factor. VOD with fatal outcome occurred in a post liver-transplant recipient who had never been exposed to any agents that have the potential to induce VOD. At onset, the disease manifested clinically as gross ascites and progressive jaundice and was observed after clinically diagnosed acute graft rejection. The disease was confirmed by histologic examinations. Histologic studies of biopsy samples from this patient revealed that most small hepatic veins less than 300 microm in diameter were affected, exhibiting concentric intimal thickening with sparse inflammatory cells. A few of the hepatic veins exhibited active endotheliitis with occasional extension of inflammation to neighboring centrilobular areas. Despite intensified immunosuppression, the observed fibrous obliterative changes were irreversible. Although the cause of VOD in this patient is tentative, the damage to the endothelium, associated with acute rejection, is likely to be attributable. VOD deserves recognition as one of the causes for liver dysfunction and persistent ascites after liver transplantation.

Altered metabolism of tacrolimus in hepatic veno-occlusive disease.

Tacrolimus is widely used for the prophylaxis and treatment of graft-versus-host disease after allogeneic hematopoietic stem cell transplantation (HSCT) and graft rejection in solid organ transplantation. The metabolism of tacrolimus has been reported to be impaired in association with liver dysfunction, mostly as documented in liver transplant recipients. Hepatic veno-occlusive disease (VOD) is one of the serious complications after allogeneic HSCT. It is characterized by jaundice, fluid retention, and painful hepatomegaly, caused by endothelial cell injury resulting from the toxicity of the conditioning regimen. The impaired metabolism of tacrolimus in hepatic VOD has not previously been reported in the literature. Here, we report the notable alteration in the metabolism of tacrolimus in two patients with hepatic VOD, in whom the half-lives of tacrolimus were markedly prolonged (288 and 146 h).

Safety limit of the extent of hepatectomy for rats with moderately fatty liver: experimental study concerning living liver donor safety.

INTRODUCTION: The aim of the present study was to determine whether rats with moderately fatty liver could withstand a 90% hepatectomy, which rats with normal livers can survive. MATERIAL AND METHODS: Nine-week-old male Wistar rats were used. Normal rat chow was fed to the normal liver group, and fat-enriched rat chow was fed to the fatty liver group for 4 weeks to induce a moderately fatty liver. The authors have previously reported that this fatty liver rat model can cause fatal liver dysfunction after reduced-size-liver transplantation. A 90% and 95% hepatectomy were performed using rats of both groups to evaluate posthepatectomized liver function. RESULTS: All rats undergoing a 90% hepatectomy were still alive 30 days after the hepatectomy, but the rats that underwent a 95% hepatectomy were all dead within 4 days regardless of group. Increases in the liver remnant wet weight measured until 7 postoperative days after 90% hepatectomy were almost similar among the two groups. Alanin aminotransferase measured at 24, 48, 72, and 168 h after a 90% hepatectomy were significantly higher in the fatty liver group than in the normal liver group. Similarly, at up to 72 h postoperatively, the serum hyarulonic acids were significantly higher in the fatty liver group. CONCLUSION: A moderately fatty liver did not cause mortality in 90% hepatectomized rats. However, it caused a higher degree of hepatic parenchymal as well as sinusoidal injury.

Paracetamol induced hepatotoxicity.

AIM: To identify the clinical and biochemical risk factors associated with outcome of paracetamol induced significant hepatotoxicity in children. METHODS: Retrospective case notes review of those with paracetamol overdose admitted from 1992 to 2002. Patients were analysed in two groups: group I recovered after conservative treatment and group II developed progressive liver dysfunction and were listed for liver transplantation. RESULTS: Of 51 patients (6 males, 45 females, aged 0.8-16.1 years), 6 (aged <7 years) received cumulative multiple doses, and 45 a single large overdose (median 345 mg/kg, range 91-645). The median (range) interval to hospital at presentation post-ingestion was 24 hours (4-65) and 44 hours (24-96) respectively in groups I and II. Patients received standard supportive treatment including N-acetylcysteine. All children in group I survived. In group II, 6/11 underwent orthotopic liver transplantation (OLT) and 2/6 survived; 5/11 died awaiting OLT. Cerebral oedema was the main cause of death. Children who presented late to hospital for treatment and those with progressive hepatotoxicity with prothrombin time >100 seconds, hypoglycaemia, serum creatinine >200 micromol/l, acidosis (pH <7.3), and who developed encephalopathy grade III, had a poor prognosis or died. Although hepatic transaminase levels were markedly raised in both groups, there was no correlation with necessity for liver transplantation or death. CONCLUSION: Accidental or incidental paracetamol overdose in children may be associated with toxic liver damage leading to fulminant liver failure. Delayed presentation and/or delay in treatment, and hepatic encephalopathy > or =grade III were significant risk factors, implying poor prognosis and need for OLT. Prompt identification of high risk patients, referral to a specialised unit for management, and consideration for liver transplantation is essential.

Breast cancer-associated antigen CA 15.3 in liver cirrhosis.

The tumor marker CA 15.3 was studied in 85 patients with liver cirrhosis. Nine patients (10.6%) had abnormal levels of CA 15.3 with the highest values in cases of Child's C patients. However, Child's classes were not significantly associated with the level of the antigen. We found significant correlations with some laboratory tests, especially IgA. All patients with an elevated CA 15.3 value also had abnormal levels of IgA, and multivariate analysis showed that IgA was the only independent factor associated with CA 15.3. Although IgA is a marker of alcoholic liver disease, other markers of alcoholism were not associated with CA 15.3. Cytolysis and cholestasis were not significantly associated with the CA 15.3 level, but liver dysfunction seemed to be involved. Liver disease does not substantially limit the usefulness of CA 15.3 in the cancer patient who also has liver cirrhosis, since both the percentage of abnormal values and the elevation of the serum levels are moderate in cirrhotic patients.

[The significance of obesity in UOEH medical students--multiple regression analysis of the annual physical checkup data in 1991].

For the purpose of evaluating the significance of obesity in a young population as a risk factor toward various chronic diseases, a multiple regression analysis was performed on the data from the annual physical checkup of medical students of UOEH in 1991. The following results were obtained. (1) The average obesity index of the students showed a progressive and significant increase in the past 13 years from 1979 to 1991. (2) A close correlation between the obesity index and serum GPT was recognized by elevation of the standard partial regression coefficient of serum GPT to obesity index and that of obesity index to serum GPT when the data from all 617 students was analysed in one group. This finding was intensified in 142 obese students with an obesity index of over 10%, but it was not seen in the remaining non-obese students. (3) The correlation between the obesity index and serum GPT was found solely in the group of students with constant obesity; i.e., whose obesity index was always more than 10% during a maximum of 9 years in the past. (4) Systolic blood pressure was related to the red blood cell count rather than to the obesity index in this young population. (5) No particularly close correlation to serum cholesterol was found with any of 10 representative items examined in this physical checkup, including the obesity index, indicating that the other factors should be related to serum cholesterol levels. From the above findings, it can be concluded that constant obesity in students is related to liver dysfunction, probably due to fatty liver frequently seen in the precise examination of these individuals.

[Sarcomatoid liver carcinoma diagnosed clinically as hemangioma].

This is a case report of a 69-year-old woman with sarcomatoid hepatocellular carcinoma (HCC), which was diagnosed clinically as hemangioma. She was first admitted to our university hospital, complaining of general fatigue in December, 1988, and cholelithiasis and liver cirrhosis with hepatic tumor in Segment 8 were diagnosed. The serum AFP level was within normal range, and the tumor was diagnosed as hemangioma radiologically. She underwent only cholecystectomy and was well without any therapy for the liver tumor up until March in 1991 when she was readmitted to our university hospital due to rapidly progressive liver dysfunction. The size of the liver tumor was unchanged. Despite intensive care, she died of hepatic failure due to cirrhosis in a decompensation state. At autopsy, a well defined yellowish white tumor of 3 cm in maximum diameter was seen in the cirrhotic liver. Although the largest part of the tumor revealed necrosis and hyalinization, a sarcomatoid part composed of spindle-shaped cells was noted in the peripheral portion. In addition, some necrotic ghost cells, probably hepatocellular carcinoma, were also noted. Low molecular cytokeratin, which is always found in HCCs, was seen in spindle-shaped sarcomatoid cells. The liver tumor was diagnosed as sarcomatoid HCC from these pathological findings. We report this histologically unusual HCC with an immunohistochemical study.
