The key parameters examined included resolution rates, treatment duration, and recurrence.RESULTSA comprehensive literature search yielded 13 studies that met the inclusion criteria, comprising 4 retrospectivecohort studies and 8 case studies. The incidence of CA following liver transplantation ranges from 0.6% to 4.7%.The onset varied, with a median time to diagnosis of 10 days after transplantation. A LFD with MCT supplementationwas used as the first-line therapy in 83.3% of the studies, with resolution rates ranging from 62.5% to100%. Octreotide therapy was utilized in 66.7% of the studies, primarily as a second-line therapy, with resolutionrates of 83.3% to 100%. Combination therapy showed a significantly higher resolution rate than did dietarymanagement alone (97.8% vs 78.9%, P = 0.02). The time to resolution was significantly shorter with octreotidecontainingregimens than with dietary management alone (median, 7 days vs 14 days;P = 0.03).CONCLUSIONA stepwise approach to CA management is recommended, initiating dietary interventions and escalating tooctreotide when necessary. Further research through well-designed randomized controlled trials is essential toestablish standardized treatment protocols for optimizing patient outcomes.展开更多

Methods: Sixty-eight cases with ascites were divided into 3 groups based on their etiology, namely malignant ascites, tubercular ascites and non-tubercular benign ascites. CEA, Tch, and ADA were measured and analyzed in different ascites. Results: CEA was significantly higher in malignant ascites than in benign ascites, the sensitivity and specificity for malignant ascites being 50% and 100% respectively. Tch is higher or equal to 1.54 mmol/L in tubercular ascites and lower or equal to 1.18 mmol/L in non-tubercular benign ascites, and Tch level in malignant ascites was frequently between that in tubercular acites and non-tubercular benign ascites. Ascitic fluid ADA activity was higher than 30 U/L in 80% of tubercular ascites, while none of non-tubercular benign ascites reached to such level. Conclusion: CEA, Tch and ADA are valuable for the diagnosis and differential diagnosis of ascitic etiology and combine measurements of these indices can increase the diagnostic efficiency.展开更多

METHODS： Ascitic leptin, TNFα and serum leptin levels were measured in 77 patients with ascites （35 with malignancies, 30 cirrhosis and 12 tuberculosis）. Control serum samples were obtained from 20 healthy subjects. Leptin and TNFα levels were measured by EUSA. Body mass index （BMI） and percentage of body fat （BFM） by skin fold measurement were calculated for all patients and control groups. Peritoneal biopsy, ascites cytology and cultures or biochemical values were used for the diagnosis of patients. RESULTS： In patients with malignancies, the mean serum and ascites leptin levels and their ratios were significantly decreased compared to the other patient groups and controls. In tuberculosis peritonitis, ascitic fluid TNFα levels were significantly higher than malignant ascites and cirrhotic sterile ascites. BMI and BFM values did not distinguish between patients and controls. CONCLUSION： In patients with malignant ascites, levels of leptin and TNFα were significantly lower than in patients with tuberculous ascites.展开更多

We evaluated medical records of cirrhotic patients who were hospitalized from January 2012 to January 2014 at the Gastroenterology Department of "Hospital General de México Dr. Eduardo Liceaga", we included 51 cirrhotic patients with ascites fluid infection(AFI), and 50 non-infected cirrhotic patients as control group. Receiver operator characteristic curves were used to identify the best cutoff value of several parameters from hematic cytometry, including MPV, to predict the presence of ascites fluid infection.RESULTS: Of the 51 cases with AFI, 48 patients(94.1%) had culture-negative neutrocytic ascites(CNNA), 2(3.9%) had bacterial ascites, and one(2%)had spontaneous bacterial peritonitis. Infected patients had greater count of leucocytes and polymorphonuclear cells, greater levels of MPV and cardiac frequency(P < 0.0001), and lower mean arterial pressure compared with non-infected patients(P = 0.009). Leucocytes, polymorphonuclear count, MPV and cardiac frequency resulted to be good or very good predictive variables of presence of AFI in cirrhotic patients(area under the receiving operating characteristic > 0.80). A cutoff MPV value of 8.3 fl was the best to discriminate between cirrhotic patients with AFI and those without infection. CONCLUSION: Our results support that MPV can be an useful predictor of systemic inflammatory response syndrome in cirrhotic patients with AFI, particularly CNNA.展开更多

It is important to distinguish noncirrhotic from cirrhotic causes of ascites to guide therapy in patients with noncirrhotic ascites. Mild to moderate ascites is treated by salt restriction and diuretic therapy. The diuretic of choice is spironolactone. A combination treatment with furosemide might be necessary in patients who do not respond to spironolactone alone. Tense ascites is treated by paracentesis, followed by albumin infusion and diuretic therapy. Treatment options for refractory ascites include repeated paracentesis and transjugular intrahepatic portosystemic shunt placement in patients with a preserved liver function. Potential complications of ascites are spontaneous bacterial peritonitis (SBP) and hepatorenal syndrome (HRS). SBP is diagnosed by an ascitic neutrophil count > 250 cells/mm3 and is treated with antibiotics. Patients who survive a first episode of SBP or with a low protein concentration in the ascitic fluid require an antibiotic prophylaxis. The prognosis of untreated HRS type 1 is grave. Treatment consists of a combination of terlipressin and albumin. Hemodialysis might serve in selected patients as a bridging therapy to liver transplantation. Liver transplantation should be considered in all patients with ascites and liver cirrhosis.展开更多

METHODS: From August 2006 to March 2008, the laparoscopic approach was used to perform CHIPC on 16 patients with malignant ascites induced by gastric cancer or postoperative intraperitoneal seeding. Each patient underwent CHIPC three times after laparoscopeassisted perfusion catheters placing. The first session was completed in operative room under general anesthesia, 5% glucose solution was selected as perfusion liquid, and 1500 mg 5 fluorouracil (5FU) and 200 mg oxaliplatin were added in the perfusion solution. The second andthird sessions were performed in intensive care unit, 0.9% sodium chloride solution was selected as perfusion liquid, and 1500 mg 5FU was added in the perfusion solution alone. CHIPC was performed for 90 min at a velocity of 450600 mL/min and an in flow temperature of 43 ± 0.2℃.RESULTS: The intraoperative course was uneventful in all cases, and the mean operative period for laparoscopeassisted perfusion catheters placing was 80 min for each case. No postoperative deaths or complications related to laparoscopeassisted CHIPC occurred in this study. Clinically complete remission of ascites and related symptoms were achieved in 14 patients, and partial remission was achieved in 2 patients. During the followup, 13 patients died 29 mo after CHIPC, with a median survival time of 5 mo. Two patients with partial remission suffered from port site seeding and tumor metastasis,and died 2 and 3 mo after treatment. Three patients who are still alive today survived 4, 6 and 7 mo, respectively. The Karnofsky marks of patients (5090) increased significantly (P < 0.01) and the general status improved after CHIPC. Thus satisfactory clinical efficacy has been achieved in these patients treated by laparoscopic CHIPC. CONCLUSION: Laparoscopeassisted CHIPC is a safe, feasible and effective procedure in the treatment of debilitating malignant ascites induced by unresectable gastric cancers.展开更多

Congenital dyserythropoietic anemia type II is the most frequent type. All types of congenital dyserythropoietic anemias distinctly share a high incidence of iron loading. Iron accumulation occurs even in untransfused patients and can result in heart failure and liver cirrhosis. We have reported about a patient who presented with liver cirrhosis and intractable ascites caused by congenital dyserythropoietic anemia type II. Her clinical course was further complicated by the development of autoimmune hemolytic anemia. Splenectomy was eventually performed which achieved complete resolution of ascites, increase of hemoglobin concentration and abrogation of transfusion requirements.展开更多
文摘BACKGROUND Transjugular intrahepatic portosystemic shunt(TIPS)has an important role in the therapy of complications of portal-hypertension-related ascites.Various guidelines now indicate that TIPS is indicated for refractory ascites(RA),but TIPS for recurrent nonrefractory ascites(RNRA)achieved better clinical results.AIM To compare the clinical outcomes of TIPS for RA and RNRA in patients with complications related to portal hypertension.METHODS There were 863 patients divided into two main categories who underwent TIPS between September 2016 and September 2021.In category 1,patients had ascites without cirrhotic gastrointestinal bleeding.The patients were divided into group A(RNRA,n=183)and group B(RA,n=217).In category 2,patients had ascites and cirrhotic gastrointestinal bleeding.The patients were divided into group C(RNRA,n=328)and group D(RA,n=135).The clinical outcomes were probability of total hepatic impairment,incidence of hepatic encephalopathy(HE)and mortality.RESULTS The symptoms of ascites disappeared or were relieved within 1 week in group A compared with group B(P=0.032),and in group C compared with group D(P=0.027).By the end of follow-up,there were significant differences in the rate of RA in group A compared with group B(P=0.016),and in group C compared with group D(P=0.012).The probability of total hepatic impairment was significantly different in group A compared with group B(P=0.024),and in group C compared with group D(P=0.019).The total incidence of HE was significantly different in group A compared with group B(P=0.008),and in group C compared with group D(P=0.004).The 6-month,and 1-,2-and 3-year survival rates were significantly different between groups A and B(all P<0.05),and between groups C and D(all P<0.05).CONCLUSION TIPS has a good therapeutic effect on ascites related to cirrhotic portal hypertension,and early TIPS for RNRA can prolong survival,and prevent progression to RA.

文摘BACKGROUND Acute pancreatitis(AP)is a severe condition,and abdominal effusion is a significant predictor of its severity and prognosis.However,the relationship between ascites characteristics and AP outcomes remains undefined.AIM To assess the correlation between ascites characteristics and clinical prognosis in AP patients by comparing color depth and turbidity of early ascites.METHODS This study included 667 AP patients with ascites,categorized by color and turbidity into yellow clear(n=54),yellow turbid(n=293),red brown(n=320).The trendχ2 test was employed to analyze the incidence of organ failure(OF),infected pancreatic necrosis(IPN),and mortality across groups.Receiver operating charac teristic(ROC)curves were used to evaluate the predictive value of ascites cell count,amylase,protein,and lactate dehydrogenase(LDH)for abdominal compartment syndrome(ACS)and intra-abdominal hemorrhage.RESULTS AP patients with ascites exhibited higher scores of scoring systems(such as Bedside index for severity in AP,Acute Physiology and Chronic Health Examination II,etc.)and increased complications and mortality rates(all P<0.05)compared to those without ascites.A linear association was observed between ascites color depth and turbidity and the incidence of OF,pancreatic necrosis,IPN,and mortality(P<0.05).LDH in ascites demonstrated high accuracy in predicting ACS and intra-abdominal hemorrhage,with areas under the ROC curve of 0.77 and 0.79,respectively.CONCLUSION Early in AP,ascites correlates with OF,IPN,and mortality,showing linear associations with color depth and turbidity.Ascitic LDH reliably predicts ACS and intra-abdominal hemorrhage in AP patients.
文摘Acute pancreatitis(AP)is a complex and potentially life-threatening inflammatory condition with a highly variable clinical course,ranging from mild,selflimiting episodes to severe necrotizing forms.Among its common complications ascites has traditionally been viewed as a passive byproduct of peritoneal inflammation and enzymatic leakage with limited diagnostic or prognostic utility.However,growing evidence challenges this perspective,suggesting that ascitic fluid in AP represents a dynamic and clinically meaningful component of disease progression.In this editorial we reflected on the findings presented by Rao et al,who highlighted the diagnostic,prognostic,and therapeutic significance of ascitic fluid in AP.Easily accessible markers such as lactate dehydrogenase may provide early prognostic insight while emerging molecular biomarkers and cytokine pro-files offer promise for more precise risk stratification and individualized therapy.We argue that the systematic evaluation of ascitic fluid should be integrated into the clinical management of moderate to severe AP.Incorporating ascites analysis into standard diagnostic protocols may enhance early risk assessment,inform therapeutic decisions,and ultimately improve patient outcomes.Ascitic fluid should be recognized as a clinically valuable marker and an important source of information in the evolving landscape of AP care.
文摘BACKGROUND Chylous ascites(CA),which is characterized by lymphatic leakage into the peritoneal cavity,is a rare but significant complication of liver transplantation.Although dietary and pharmacological strategies have shown effectiveness in managing CA,standardized treatment protocols have yet to be established.AIMTo evaluate the comparative effectiveness of low-fat diet (LFD) enriched with medium-chain triglycerides (MCTs)vs octreotide therapy in managing post-liver transplantation CA.METHODSA comprehensive literature review was conducted to analyze the outcomes of dietary interventions and octreotidetherapy. The key parameters examined included resolution rates, treatment duration, and recurrence.RESULTSA comprehensive literature search yielded 13 studies that met the inclusion criteria, comprising 4 retrospectivecohort studies and 8 case studies. The incidence of CA following liver transplantation ranges from 0.6% to 4.7%.The onset varied, with a median time to diagnosis of 10 days after transplantation. A LFD with MCT supplementationwas used as the first-line therapy in 83.3% of the studies, with resolution rates ranging from 62.5% to100%. Octreotide therapy was utilized in 66.7% of the studies, primarily as a second-line therapy, with resolutionrates of 83.3% to 100%. Combination therapy showed a significantly higher resolution rate than did dietarymanagement alone (97.8% vs 78.9%, P = 0.02). The time to resolution was significantly shorter with octreotidecontainingregimens than with dietary management alone (median, 7 days vs 14 days;P = 0.03).CONCLUSIONA stepwise approach to CA management is recommended, initiating dietary interventions and escalating tooctreotide when necessary. Further research through well-designed randomized controlled trials is essential toestablish standardized treatment protocols for optimizing patient outcomes.
文摘BACKGROUND Refractory ascites(RA)and spontaneous bacterial peritonitis(SBP)are severe complications of decompensated cirrhosis,contributing to high morbidity and mortality.RA develops when ascites persists despite maximum diuretic therapy,while SBP arises from bacterial translocation and immune dysfunction in cirrhotic patients with ascites.Identifying key risk factors associated with these conditions is crucial for early intervention and improved patient outcomes.AIM To assess clinical and biochemical predictors of RA and SBP in a cohort of hospitalized patients with cirrhotic ascites.METHODS A retrospective chart review was conducted on patients with cirrhotic ascites diagnosed with RA or SBP at University Medical Center,El Paso,from July 1,2013 to December 31,2023.Patient demographics,clinical history,laboratory parameters,ascitic fluid analysis,and cirrhosis severity scores[Model for End-Stage Liver Disease-Sodium(MELD-Na)and Child-Pugh]were recorded.Statistical analyses,including multivariate logistic regression,were performed to identify independent predictors of RA and SBP,with a significance threshold of P<0.05.RESULTS A total of 179 patients were included,with a mean age of 59.08±13.04 years,predominantly male(55.9%)and Hispanic(98.3%).The most common etiology of cirrhosis was alcohol-related liver disease(45.3%),and most patients had Grade III ascites(95.5%).Among them,115(64.2%)had RA,and 57(31.8%)had SBP.RA was significantly associated with abnormal serum potassium levels[odds ratio(OR)=2.27,95%CI:1.06–4.84,P=0.034],while SBP was independently predicted by gastrointestinal bleeding(OR=2.59,95%CI:1.18–5.64,P=0.017)and thrombocytopenia(platelet count<50000;OR=3.27,95%CI:1.08–9.88,P=0.035).CONCLUSION RA and SBP are major complications of cirrhosis,with electrolyte imbalances and coagulopathy playing key roles in their development.Our study confirms that abnormal potassium levels significantly predict RA,while gastrointestinal bleeding and thrombocytopenia are strong predictors of SBP.These findings emphasize the need for early risk stratification and targeted management strategies to improve outcomes in high-risk cirrhotic patients,particularly in minority populations with limited healthcare access.Further prospective studies are warranted to validate these results and explore potential interventions to reduce RA and SBP incidence.

文摘Ovarian cancer remains a leading cause of gynecological cancer mortality1,and patients with advanced stage ovarian cancer frequently develop malignant ascites that foster immunosuppressive microenvironments and therapeutic resistance2,3.Although ascites have traditionally been considered detrimental,we report a paradoxical role in which they enhance the cytotoxicity ofγδT cells—a unique T cell subset that can be allogenically transferred for cancer treatment4,5—toward ovarian cancer.
文摘BACKGROUND Diagnostic laparoscopy is a minimally invasive surgical method to diagnose intra-abdominal diseases.AIM To evaluate patients with unexplained ascites who could not be definitively diagnosed via advanced radiological and endoscopic methods and serological,cytological,and microbiological examinations and,therefore,underwent diag-nostic laparoscopy.METHODS This retrospective analysis evaluated 82 patients who underwent diagnostic laparoscopy due to unexplained ascites.Patients’medical records were obtained from the hospital database.Their age,sex,complaints at admission,laboratory results,radiological imaging results,diagnostic laparoscopy reports,and pa-thology reports were analyzed.RESULTS The serum-ascites albumin gradient was<1.1 in 96.3%of the patients(n=79).Among patients,22(26.8%)had benign diagnoses and 60(73.2%)had malignant diagnoses.In addition,55(67.1%)were deceased,and the median follow-up time from diagnosis to death was four months.The overall follow-up time ranged from 1 to 142 months,with a median of 14 months.Patients’diagnoses were significantly associated with their survival(P<0.05,χ2 test).The mortality rate was 86.7%among patients with malignant diagnoses and 13.6%among patients with benign diagnoses.CONCLUSION Diagnostic laparoscopy is minimally invasive,has a low complication rate,and requires a short hospital stay.It can be safely performed to diagnose and treat ascites that remain unexplained after advanced radiological and endoscopic examinations.
文摘BACKGROUND Petersen’s hernia occurring through the epiploic foramen of the greater omentum,is an uncommon type of internal hernia.When it presents with complications such as chylous ascites,which is the lymphatic fluid accumulation in the abdominal cavity,it is particularly rare.Following laparoscopic total gastrectomy and Roux-en-Y anastomosis,the incidence of this condition is exceedingly low.CASE SUMMARY A 62-year-old male patient developed Petersen’s hernia following laparoscopic total gastrectomy(LTG)for gastric cancer,after Roux-en-Y anastomosis.Intestinal torsion and obstruction were experienced by the patient,along with a small amount of chylous ascites.Imaging studies and clinical assessment confirmed the diagnosis.Emergency surgery was performed promptly for the patient in the operating room.The twisted small intestine was reduced and the defect in Petersen’s space was repaired.The procedure was successful in the correction of the intestinal torsion and approximation of the hernia without the need for bowel resection.The patient’s condition significantly improved following the surgery.The ascites evolved from a milky white appearance to a pale yellow,with a substantial decrease in the triglyceride levels in the ascitic fluid,implying a favorable recovery trajectory.The patient was monitored closely and received appropriate care postoperatively,including nutritional support and fluid management.CONCLUSION This report illustrates the significance of recognizing Petersen’s hernia as a potential complication following gastrectomy for gastric cancer.It highlights the fundamental role of early surgical intervention in the effective management of such complications.The favorable outcome in this patient illustrates that prompt and appropriate surgical management can deter the necessity for more extensive procedures such as bowel resection.
文摘BACKGROUND Chylous ascites is an uncommon condition,occurring in less than 1%of ascites cases.It results from traumatic or obstructive disruption of the lymphatic system,causing the leakage of thoracic or intestinal lymph into the abdominal cavity.This leads to the accumulation of a milky,triglyceride-rich fluid.In adults,malignancy and cirrhosis are the primary causes of chylous ascites.Notably,chylous ascites accounts for only 0.5%to 1%of all cirrhosis-related ascites cases.At present,there is a limited understanding of this condition,and effective timely management in clinical practice remains challenging.CASE SUMMARY This case report presents a patient with hepatic cirrhosis complicated by chylous ascites,who had experienced multiple hospitalizations due to abdominal distension.Upon admission,comprehensive examinations and assessments were conducted.The treatment strategy focused on nutritional optimization through a low-sodium,low-fat,and high-protein diet supplemented with medium-chain triglycerides,therapeutic paracentesis,and diuretics.Following a multidiscip-linary discussion and thorough evaluation of the patient’s condition,surgical indications were confirmed.After informing the patient about the benefits and risks,and obtaining consent,a transjugular intrahepatic portosystemic shunt procedure was performed,successfully alleviating the abdominal swelling symptoms.This article details the clinical characteristics and treatment approach for this uncommon case,summarizing current management methods for hepatic cirrhosis complicated by chylous ascites.The aim is to provide valuable insights for clinicians encountering similar situations.CONCLUSION Optimizing nutrition and addressing the underlying cause are essential in the treatment of chylous ascites.When conservative approaches prove ineffective,alternative interventions such as transjugular intrahepatic portosystemic shunt may be considered.

文摘BACKGROUND Ascites is the most common complication of cirrhosis.Current pharmacological interventions,such as diuretics,often become ineffective in advanced stages due to diuretic resistance.Sodium-glucose co-transporter 2(SGLT2)inhibitors have demonstrated potential in enhancing urinary sodium excretion and mitigating sodium-fluid retention.This study aims to evaluate the effects of SGLT2 inhibitors on the fractional excretion of sodium(FENa)in patients with cirrhotic ascites.AIM To determine whether adjunctive therapy with the SGLT2 inhibitor empagliflozin increases FENa compared with standard care alone in patients with cirrhosis and refractory ascites,and to evaluate its short-term safety profile.METHODS The effect of SGLT2 inhibitor empagliflozin on FENa in patients with cirrhosis and refractory ascites is a multicenter,open-label,randomized controlled trial.A total of 70 patients with refractory ascites secondary to cirrhosis will be enrolled and randomly assigned to receive either empagliflozin 10 mg daily plus standard care or standard care alone for 14 consecutive days.The primary outcome is the change in FENa from baseline to day 14.Secondary outcomes include 24-hour urinary sodium excretion,urine volume,ascites volume(assessed by ultrasound),body weight,and safety indicators.Exploratory outcomes include changes in components of the reninangiotensin-aldosterone system.RESULTS This article reports the study protocol only.No participant data have been collected or analyzed for this manuscript.CONCLUSION This protocol evaluates whether empagliflozin,added to standard therapy,increases sodium excretion and reduces fluid overload in refractory ascites.

文摘For cirrhotic refractory ascites,diuretics combined with albumin and vasoactive drugs are the first-line choice for ascites management.However,their therapeutic effects are limited,and most refractory ascites do not respond to medication treat-ment,necessitating consideration of drainage or surgical interventions.Con-sequently,numerous drainage methods for cirrhotic ascites have emerged,including large-volume paracentesis,transjugular intrahepatic portosystemic shunt,peritoneovenous shunt,automated low-flow ascites pump,cell-free and concentrated ascites reinfusion therapy,and peritoneal catheter drainage.This review introduces the advantages and disadvantages of these methods in different aspects,as well as indications and contraindications for this disease.
文摘Objective: To study the value of combined determination of carcinoembryonic antigen (CEA), total cholesterol (Tch) and adenosine deaminase (ADA) in the differential diagnosis of ascites due to different causes. Methods: Sixty-eight cases with ascites were divided into 3 groups based on their etiology, namely malignant ascites, tubercular ascites and non-tubercular benign ascites. CEA, Tch, and ADA were measured and analyzed in different ascites. Results: CEA was significantly higher in malignant ascites than in benign ascites, the sensitivity and specificity for malignant ascites being 50% and 100% respectively. Tch is higher or equal to 1.54 mmol/L in tubercular ascites and lower or equal to 1.18 mmol/L in non-tubercular benign ascites, and Tch level in malignant ascites was frequently between that in tubercular acites and non-tubercular benign ascites. Ascitic fluid ADA activity was higher than 30 U/L in 80% of tubercular ascites, while none of non-tubercular benign ascites reached to such level. Conclusion: CEA, Tch and ADA are valuable for the diagnosis and differential diagnosis of ascitic etiology and combine measurements of these indices can increase the diagnostic efficiency.
文摘AIM： To evaluate the role of leptin levels in the differentia diagnosis of ascites. METHODS： Ascitic leptin, TNFα and serum leptin levels were measured in 77 patients with ascites （35 with malignancies, 30 cirrhosis and 12 tuberculosis）. Control serum samples were obtained from 20 healthy subjects. Leptin and TNFα levels were measured by EUSA. Body mass index （BMI） and percentage of body fat （BFM） by skin fold measurement were calculated for all patients and control groups. Peritoneal biopsy, ascites cytology and cultures or biochemical values were used for the diagnosis of patients. RESULTS： In patients with malignancies, the mean serum and ascites leptin levels and their ratios were significantly decreased compared to the other patient groups and controls. In tuberculosis peritonitis, ascitic fluid TNFα levels were significantly higher than malignant ascites and cirrhotic sterile ascites. BMI and BFM values did not distinguish between patients and controls. CONCLUSION： In patients with malignant ascites, levels of leptin and TNFα were significantly lower than in patients with tuberculous ascites.
文摘Refractory ascites(RA)is a frequent and life-threatening complication of cirrhosis.In selected patients with RA,transjugular intrahepatic portosystemic shunt(TIPS)placement and liver transplantation(LT)are currently considered the best therapeutic alternatives to repeated large volume paracentesis.In patients with a contraindication to TIPS or LT,the alfapump®system(Sequana Medical,Ghent,Belgium)has been developed to reduce the need for iterative paracentesis,and consequently to improve the quality of life and nutritional status.We report here recent data on technical progress made since the first implantation,the efficacy and tolerance of the device,the position of the pump in the therapeutic arsenal for refractory ascites,and the grey areas that remain to be clarified regarding the optimal selection of patients who are potential candidates for this treatment.
文摘AIM: To identify a mean platelet volume(MPV) cutoff value which should be able to predict the presence of bacterial infection.METHODS: An observational, analytic, retrospective study. We evaluated medical records of cirrhotic patients who were hospitalized from January 2012 to January 2014 at the Gastroenterology Department of "Hospital General de México Dr. Eduardo Liceaga", we included 51 cirrhotic patients with ascites fluid infection(AFI), and 50 non-infected cirrhotic patients as control group. Receiver operator characteristic curves were used to identify the best cutoff value of several parameters from hematic cytometry, including MPV, to predict the presence of ascites fluid infection.RESULTS: Of the 51 cases with AFI, 48 patients(94.1%) had culture-negative neutrocytic ascites(CNNA), 2(3.9%) had bacterial ascites, and one(2%)had spontaneous bacterial peritonitis. Infected patients had greater count of leucocytes and polymorphonuclear cells, greater levels of MPV and cardiac frequency(P < 0.0001), and lower mean arterial pressure compared with non-infected patients(P = 0.009). Leucocytes, polymorphonuclear count, MPV and cardiac frequency resulted to be good or very good predictive variables of presence of AFI in cirrhotic patients(area under the receiving operating characteristic > 0.80). A cutoff MPV value of 8.3 fl was the best to discriminate between cirrhotic patients with AFI and those without infection. CONCLUSION: Our results support that MPV can be an useful predictor of systemic inflammatory response syndrome in cirrhotic patients with AFI, particularly CNNA.
文摘BACKGROUND The lymphatic system is crucial in maintaining the body fluid homeostasis.A dysfunctional lymphatic system may contribute to the refractoriness of ascites and edema in cirrhosis patients.Therefore,assessment of lymphatic dysfunction in cirrhosis patients with refractory ascites(RA)can be crucial as it would call for using different strategies for fluid mobilization.AIM To assessing the magnitude,spectrum,and clinical associations of lymphatic dysfunction in liver cirrhosis patients with RA.METHODS This observational study included 155 consecutive cirrhosis patients with RA.The presence of clinical signs of lymphedema,such as peau d’orange appearance and positive Stemmer sign,intestinal lymphangiectasia(IL)on duodenal biopsy seen as dilated vessels in the lamina propria with strong D2-40 immunohistochemistry,and chylous ascites were used to diagnose the overt lymphatic dysfunctions.RESULTS A total of 69(44.5%)patients out of 155 had evidence of lymphatic dysfunction.Peripheral lymphedema,found in 52(33.5%)patients,was the most common manifestation,followed by IL in 42(27.0%)patients,and chylous ascites in 2(1.9%)patients.Compared to patients without lymphedema,those with lymphedema had higher mean age,median model for end-stage liver disease scores,mean body mass index,mean ascitic fluid triglyceride levels,and proportion of patients with hypoproteinemia(serum total protein<5 g/dL)and lymphocytopenia(<15%of total leukocyte count).Patients with IL also had a higher prevalence of lymphocytopenia and hypoproteinemia(28.6%vs.9.1%,P=0.004).Seven(13%)patients with lymphedema had lower limb cellulitis compared to none in those without it.On multivariate regression analysis,factors independently associated with lymphatic dysfunction included obesity[odds ratio(OR):4.2,95%confidence intervals(95%CI):1.1–15.2,P=0.027],lymphocytopenia[OR:6.2,95%CI:2.9–13.2,P<0.001],and hypoproteinemia[OR:3.7,95%CI:1.5–8.82,P=0.003].CONCLUSION Lymphatic dysfunction is common in cirrhosis patients with RA.Significant indicators of its presence include hypoproteinemia and lymphocytopenia,which are likely due to the loss of lymphatic fluid from the circulation.Future efforts to mobilize fluid in these patients should focus on methods to improve lymphatic drainage.
文摘BACKGROUND Natriuretic peptides are involved in the cascade of pathophysiological events occurring in liver cirrhosis,counterbalancing vasoconstriction and anti-natriuretic factors.The effects of natriuretic peptides as treatment of cirrhotic ascites have been investigated only in small studies,and definitive results are lacking.AIM To examine the effects and safety of natriuretic peptides in cirrhosis patients with ascites.METHODS We searched MEDLINE,Web of Science,Scopus,Cochrane Library and Embase for all available studies applying intravenous administration of any natriuretic peptide to patients suffering from cirrhotic ascites.Inclusion was not limited by treatment duration or dose,or by follow-up duration.Both randomised controlled trials and non-randomised studies were eligible for inclusion.The primary outcome was change in renal sodium excretion.Secondary outcomes included safety measures and changes in renal water excretion,plasma aldosterone concentration,and plasma renin activity.RESULTS Twenty-two studies were included.Atrial natriuretic peptide(ANP)was the only intensively studied treatment.Sodium excretion increased in response to continuous ANP infusion and was more pronounced when infusion rates of>30 ng/kg/min were administered compared with≤30 ng/kg/min(P<0.01).Moreover,natriuresis was significantly higher in study subgroups with mild/moderate ascites compared with moderate/severe and refractory ascites(P<0.01).ANP infusions increased renal water excretion,although without reaching a statistically significant dose-response gradient.Plasma aldosterone concentration and plasma renin activity were significantly lower at baseline in study subgroups achieving a negative sodium balance in response to an ANP administration compared with treatment non-responders(P<0.01).Blood pressure decreases occurred less frequently when ANP doses≤30 ng/kg/min were applied.The quality of evidence for a natriuretic response to ANP was low,mainly due to small sample sizes and considerable between-study heterogeneity.Data were sparse for the other natriuretic peptides;B-type natriuretic peptide and urodilatin.CONCLUSION Intravenous ANP infusions increase sodium excretion in patients with cirrhotic ascites.Continuous infusion rates>30 ng/kg/min are the most effective.However,safety increases with infusion rates≤30 ng/kg/min.
文摘Ascites is one of the major complications of liver cirrhosis and is associated with a poor prognosis. It is important to distinguish noncirrhotic from cirrhotic causes of ascites to guide therapy in patients with noncirrhotic ascites. Mild to moderate ascites is treated by salt restriction and diuretic therapy. The diuretic of choice is spironolactone. A combination treatment with furosemide might be necessary in patients who do not respond to spironolactone alone. Tense ascites is treated by paracentesis, followed by albumin infusion and diuretic therapy. Treatment options for refractory ascites include repeated paracentesis and transjugular intrahepatic portosystemic shunt placement in patients with a preserved liver function. Potential complications of ascites are spontaneous bacterial peritonitis (SBP) and hepatorenal syndrome (HRS). SBP is diagnosed by an ascitic neutrophil count > 250 cells/mm3 and is treated with antibiotics. Patients who survive a first episode of SBP or with a low protein concentration in the ascitic fluid require an antibiotic prophylaxis. The prognosis of untreated HRS type 1 is grave. Treatment consists of a combination of terlipressin and albumin. Hemodialysis might serve in selected patients as a bridging therapy to liver transplantation. Liver transplantation should be considered in all patients with ascites and liver cirrhosis.

文摘AIM:To investigate the procedure, feasibility and effects of laparoscopeassisted continuous circulatory hyperthermic intraperitoneal perfusion chemotherapy (CHIPC) in treatment of malignant ascites induced by peritoneal carcinomatosis from gastric cancers. METHODS: From August 2006 to March 2008, the laparoscopic approach was used to perform CHIPC on 16 patients with malignant ascites induced by gastric cancer or postoperative intraperitoneal seeding. Each patient underwent CHIPC three times after laparoscopeassisted perfusion catheters placing. The first session was completed in operative room under general anesthesia, 5% glucose solution was selected as perfusion liquid, and 1500 mg 5 fluorouracil (5FU) and 200 mg oxaliplatin were added in the perfusion solution. The second andthird sessions were performed in intensive care unit, 0.9% sodium chloride solution was selected as perfusion liquid, and 1500 mg 5FU was added in the perfusion solution alone. CHIPC was performed for 90 min at a velocity of 450600 mL/min and an in flow temperature of 43 ± 0.2℃.RESULTS: The intraoperative course was uneventful in all cases, and the mean operative period for laparoscopeassisted perfusion catheters placing was 80 min for each case. No postoperative deaths or complications related to laparoscopeassisted CHIPC occurred in this study. Clinically complete remission of ascites and related symptoms were achieved in 14 patients, and partial remission was achieved in 2 patients. During the followup, 13 patients died 29 mo after CHIPC, with a median survival time of 5 mo. Two patients with partial remission suffered from port site seeding and tumor metastasis,and died 2 and 3 mo after treatment. Three patients who are still alive today survived 4, 6 and 7 mo, respectively. The Karnofsky marks of patients (5090) increased significantly (P < 0.01) and the general status improved after CHIPC. Thus satisfactory clinical efficacy has been achieved in these patients treated by laparoscopic CHIPC. CONCLUSION: Laparoscopeassisted CHIPC is a safe, feasible and effective procedure in the treatment of debilitating malignant ascites induced by unresectable gastric cancers.
文摘The congenital dyserythropoietic anemias comprise a group of rare hereditary disorders of erythropoiesis, characterized by ineffective erythropoiesis as the predominant mechanism of anemia and by characteristic morphological aberrations of the majority of erythroblasts in the bone marrow. Congenital dyserythropoietic anemia type II is the most frequent type. All types of congenital dyserythropoietic anemias distinctly share a high incidence of iron loading. Iron accumulation occurs even in untransfused patients and can result in heart failure and liver cirrhosis. We have reported about a patient who presented with liver cirrhosis and intractable ascites caused by congenital dyserythropoietic anemia type II. Her clinical course was further complicated by the development of autoimmune hemolytic anemia. Splenectomy was eventually performed which achieved complete resolution of ascites, increase of hemoglobin concentration and abrogation of transfusion requirements.
