1/31. Massive pleural effusion and ascites resulting from esophagectomy with extensive lymphadenectomy for cancer of the abdominal esophagus.chylothorax is an uncommon but well recognized complication of esophagectomy. We present the case of a 57 year-old man with squamous cell carcinoma of the abdominal esophagus who underwent subtotal esophagectomy by right thoracotomy. Post-operatively, the volume of pleural effusion from the right chest was increased (1600-2000 ml/day). The effusion was straw colored, not changing to milky after meals. The characteristics and composition of the pleural fluid were similar to those of chyle. We therefore treated this patient using methods for treatment of chylothorax, conservatively, by administration of OK-432 and minocycline/hydrochloride into the pleural cavity from the chest tube with success. We discuss the pathophysiology of this unusual condition and its treatment.- - - - - - - - - - ranking = 1keywords = volume (Clic here for more details about this article) |
2/31. HHV8-negative primary effusion lymphoma of the peritoneal cavity presenting with a distinct immunohistochemical phenotype.Primary effusion lymphoma (PEL) has been recognized as a body-cavity-based lymphoma that was originally reported to be associated with human herpes virus 8 (HHV8) infection, and was frequently found in human immunodeficiency virus-positive (hiv) patients. Here we describe an autopsy case of PEL of the peritoneal cavity in an immunocompetent patient. Cytological analysis of tumor cells within ascites revealed immunocytochemical features of keratin positivity and CD45 negativity. At autopsy, the presence of a massive volume of ascites as well as diffuse tumor cell infiltrates within the serosa of the intestine and mesenterium were observed. Tumor cells were morphologically similar to anaplastic large-cell lymphoma, but were immunohistochemically positive for keratin and epithelial membrane antigen (EMA). They also showed no reactivity to representative lymphocyte surface markers including CD45, in addition to being negative for CD30 and p80NPM/ALK. Molecular analysis of the tumor cells revealed monoclonality of the immunoglobulin heavy-chain gene rearrangement which demonstrated a lymphoma of the B-cell lineage. Furthermore, HHV8 was not detected by immunohistochemical analysis, PCR or nested PCR technique. Based on these results, we consider the present case to be an HHV8-negative PEL with keratin and EMA positivity.- - - - - - - - - - ranking = 1keywords = volume (Clic here for more details about this article) |
3/31. Malignant ascites: new concepts in pathophysiology, diagnosis, and management.Malignant ascites is a manifestation of advanced malignant disease that is associated with significant morbidity. Mainstays of treatment include diuretics and recurrent large volume paracentesis. Although lymphatic obstruction has been considered the major pathophysiologic mechanism behind its formation, recent evidence suggests that immune modulators, vascular permeability factors, and metalloproteinases are contributing significantly to the process. These new observations offer the opportunity for development of new, more targeted therapies for the treatment of malignant ascites. This article uses a clinical case to highlight the problem, then reviews these new concepts in the pathophysiology of malignant ascites formation. The diagnosis and management of this challenging medical problem are subsequently discussed, with emphasis on how these new pathophysiologic insights are being applied to the development of novel therapies that may soon change how we manage this troubling clinical condition.- - - - - - - - - - ranking = 1keywords = volume (Clic here for more details about this article) |
4/31. Chemical pleurodesis for hepatic hydrothorax.BACKGROUND: ascites can occur after hepatic diseases causing dyspnea, coughing and pain. When associated with pleural effusion it can also increase respiratory distress. In a bibliographic survey hydrothorax has been observed in up to 20% of the patients and the kind of treatment is still being discussed. OBJECTIVE: This case report shows the occurrence of a large volume of ascites and pleural effusion in a cirrhotic patient and his treatment. methods: Report the case of a patient with hepatic cirrhosis due to chronic alcoholism and massive pleural effusion and ascites. He was submitted to several pleural paracenteses without success. Scintigraphy showed the presence of ascites and confirmed a possible pleuroperitoneal communication. The thoracic surgery group was called and after evaluation it was decided to submit the patient to a pulmonary decortication and chemical pleurodesis. RESULTS: These procedures were carried out with success. The pleural effusion was solved and the treatment of ascites was decided upon because the patient did not accept any surgical procedure. CONCLUSION: This treatment could be applied to patients with hydrothorax who could not be submitted to a liver transplantation.- - - - - - - - - - ranking = 1keywords = volume (Clic here for more details about this article) |
5/31. An autopsy case of Crow-Fukase (POEMS) syndrome with a high level of IL-6 in the ascites. Special reference to glomerular lesions.A 58-year-old man developed polyneuropathy, organomegaly, gynecomastia, skin pigmentation, and multiple myeloma (IgG-lambda type). Although transient clinical improvement was obtained with prednisolone and cyclophosphamide, his general condition deteriorated progressively, and he died 3 years after onset. lymph nodes showed angiofollicular hyperplasia, and the sural nerve revealed segmental demyelination. At autopsy, the glomeruli were enlarged and showed mild mesangial cell proliferation with segmental mesangiolysis and proliferation of endothelial cells forming abnormal vessels. The massive volume of ascites contained a high level of interleukin-6 (IL-6). IL-6, a multifunctional cytokine, may be the pathogenic factor which induces the various clinical symptoms and pathological features of Crow-Fukase (POEMS) syndrome.- - - - - - - - - - ranking = 1keywords = volume (Clic here for more details about this article) |
6/31. Intravascular embolization therapy in a patient with an enlarged polycystic liver.Because the kidneys in patients with autosomal dominant polycystic kidney disease (ADPKD) are usually supplied by well-developed arteries, the authors attempted renal contraction therapy in such patients with renal transcatheter arterial embolization (TAE) using intravascular coils. In most patients with marked nephromegaly, renal TAE was effective. However, in patients with marked hepatomegaly without significant nephromegaly, renal TAE was not effective, and hepatic treatment was always required. In June 2001, the authors obtained approval for a new treatment,"TAE for enlarged polycystic liver," from an ethics committee discussing new treatment at their hospital. A 56-year-old man undergoing hemodialysis for 2 months was referred to the authors' institute with the complaint of severe abdominal distension and loss of appetite in March 2001. Most of the liver (about 90%) had been replaced by multiple cysts, and near-intact hepatic parenchyma was quite scarce. The kidneys were quite small compared with the liver. angiography results showed that almost all hepatic arterial branches were well developed, although most of the portal vein was obstructed, and only the left medial portal vein was spared; the former corresponded to the hepatic region replaced by multiple cysts and the latter to the preserved intact hepatic parenchyma. The target of TAE was the hepatic arterial branches of the former. Microcoils were used as embolization material. Two years after TAE, abdominal distension has markedly decreased because of decrease in liver size (to 54% of the previous value), and muscle and fat volume in the thoracic region have increased owing to improvement of appetite. ascites became obscure. Nutrition and activities of daily living have improved. Hepatic TAE may be an option for treatment of patients in poor condition with symptomatic polycystic liver.- - - - - - - - - - ranking = 1keywords = volume (Clic here for more details about this article) |
7/31. Massive fetal ascites causing increased middle cerebral artery systolic velocity.BACKGROUND: An elevated peak systolic velocity in the middle cerebral artery, assessed by Doppler ultrasonography, is commonly associated with fetal anemia. Other fetal abnormalities associated with a high middle cerebral artery velocity have rarely been reported. CASE: A fetus with increasing ascites was found to have an elevated middle cerebral artery peak systolic velocity. Following paracentesis, the peak systolic velocity normalized. Peak systolic velocity continued to correlate with the level of ascites, falling to normal ranges when large-volume amniocentesis and paracentesis were performed. At birth, the infant was found to have a normal hematocrit. CONCLUSION: An elevated middle cerebral artery peak systolic velocity may result from massive fetal ascites without anemia. We hypothesize that the massive ascites led to increased afterload of the heart, with relatively preserved preload, leading to an increased systolic blood pressure and an elevated middle cerebral artery peak systolic velocity.- - - - - - - - - - ranking = 1keywords = volume (Clic here for more details about this article) |
8/31. ascites reinfusion dialysis (ARD) for renal failure with refractory ascites.BACKGROUND: dialysis is difficult for patients who have simultaneous liver and kidney failure. Effective mobilization of ascites is rare, and hypotension is common. Combining repeated paracentesis with continuous renal replacement therapy can achieve effective volume removal with hemodynamic stability, but requires intensive care unit resources. Large amounts of albumin are lost from the body in the drained ascites. Combining ascites reinfusion with hemodialysis is a potential alternative therapy. methods: Eight treatments were undertaken in 3 patients with refractory ascites in the setting of acute onset renal failure. Hemodialysis was unsuccessful due to hypotension in each case. Two patients were treated twice, and 1 patient was treated 4 times. Each patient underwent hemodialysis with reinfusion of ascites directly into the blood inlet of the dialysis machine. Weight, blood urea nitrogen, albumin and platelet counts were measured before and after treatment. Hemodynamic tolerance was assessed, and patients were observed for the development ofencephalopathy, disseminated intravascular coagulation, infection and hemodynamic decompensation. RESULTS: All patients survived. There was 1 episode of transient hemoperitoneum, but no encephalopathy, GI bleeding or infection. One patient recovered renal function, and the other 2 were discharged ambulatory to chronic hemodialysis programs. blood pressure was supported easily during therapy, despite removal of 3-8 kg of fluid. Platelet counts decreased by 27,000 /- 13,000, and albumin increased by 0.5 /- 0.2 g/dl. All values returned to baseline over the next 1-4 days. CONCLUSIONS: ascites recirculation with dialysis is a safe and effective therapy for patients with refractory ascites and severe renal failure, which can be carried out in routine inpatient and outpatient settings. Hemodynamic tolerance was good and thrombocytopenia was modest.- - - - - - - - - - ranking = 1keywords = volume (Clic here for more details about this article) |
9/31. Outflow block secondary to stenosis of the inferior vena cava following living-donor liver transplantation?Although it is well known that outflow block is caused by stenosis or occlusion of hepatic vein anastomoses following living donor liver transplantation (LDLT), there have been few reports on inferior vena cava (IVC) stenosis following LDLT. In this paper, we report two cases of IVC stenosis and hepatic vein outflow block following right hepatic LDLT in the absence of stenosis of any of the anastomoses. Both patients presented with liver dysfunction, an ascitic fluid volume of approximately 2000 mL, and congestion in their biopsy specimens, and venocavography demonstrated IVC stenosis with gradients of more than 10 mmHg in patients with a dominant inferior right hepatic vein (IRHV) anastomosis. After a Gianturco expandable metallic stent successfully implanted in the IVC, the patient's liver function recovered and the volume of ascitic fluid decreased. The pathogenesis of hepatic vein outflow block secondary to IVC stenosis following LDLT may involve the anastomosis with the IRHV, which is the dominant draining vein of the graft and larger than the RHV, caudal to the IVC stenosis and a significant IVC pressure gradient that results in increased IRHV pressure. In conclusion, it is important to include hepatic vein outflow block in the differential diagnosis when patients who have undergone right hepatic LDLT in which anastomosis of the large IRHV has been performed develop manifestations of liver dysfunction.- - - - - - - - - - ranking = 2keywords = volume (Clic here for more details about this article) |
10/31. octreotide in the treatment of refractory ascites of cirrhosis.Dietary sodium restriction and diuretic treatment have been shown to be effective in the treatment of ascites in the majority of cirrhotic patients. However, approximately 5 to 10% of patients develop refractory ascites, which is defined as ascites that does not respond to intensive diuretic therapy (diuretic-resistant) or ascites that cannot be controlled because the patient develops diuretic-induced complications that prevent the use of an effective diuretic dose (diuretic-intractable). Current therapeutic approaches for refractory ascites include repeated large-volume paracentesis and transjugular intrahepatic portosystemic shunting. In the present report, subcutaneous octreotide treatment improved renal function and hemodynamics and diuretic response in two patients with refractory ascites in line with a marked decrease in renin and aldosterone secretion. We consider that octreotide could be of value in the management of refractory ascites in cirrhotic patients.- - - - - - - - - - ranking = 1keywords = volume (Clic here for more details about this article) |
