Incidence of primary hepatitis C infection among people who inject drugs during 2012-2020 in Athens, Greece.

One of the World Health Organization's targets for the 2030 viral hepatitis elimination strategy is to reduce new hepatitis C (HCV) infections. In Athens, Greece, people who inject drugs (PWID) have a high HCV prevalence, with increasing trends since the 2000s. This analysis aims to assess primary HCV incidence among PWID during 2012-2020. Two community-based interventions were implemented in 2012-2013 and 2018-2020 with repeated sero-behavioural surveys in each period. Participants enrolled in multiple surveys were identified through linkage. To assess trends in HCV transmission, three indicators were estimated: (i) anti-HCV prevalence among 'new' injectors (those injecting ≤2 years), (ii) indirect HCV incidence among 'new' injectors, assuming infection occurred at the midpoint between initiating injection and the first positive test, and (iii) HCV incidence from repeat participants. There were 431 and 125 'new' injectors, respectively, in 2012-2013 and 2018-2020. Αnti-HCV prevalence [95% CI] declined from 53.6% [48.8%, 58.3%] in 2012-2013 to 40.0% [31.3, 49.1%] in 2018-2020 (25.4% reduction, p = .007). The indirect estimate [95% CI] of HCV incidence among 'new' injectors decreased from 56.1 [49.3, 63.8] to 39.0/100 person-years (PYs) [29.6, 51.5] (30.5% reduction, p = .020). HCV incidence [95% CI] based on seroconversions in repeat participants (16/63 in 2012-2013 and 9/55 in 2018-2020) declined from 64.6 [39.6105.4] to 13.8/100 PYs [7.2, 26.5], respectively (78.6% reduction, p < .001). Primary HCV incidence remains high among PWID in Athens. Consistent implementation of combined interventions, including high-coverage harm reduction programs and initiatives tailored to increase access to HCV treatment, is essential to sustain the declining trends documented during 2012-2020.

HERACLIS-HDV cohort for the factors of underdiagnosis and prevalence of hepatitis D virus infection in HBsAg-positive patients.

BACKGROUND AND AIMS: Hepatitis D virus (HDV) underdiagnosis remains common. We assessed the HDV screening and prevalence rates in HBsAg-positive patients seen at tertiary liver centres throughout Greece as well as factors affecting HDV diagnosis. METHODS: All adult HBsAg-positive patients seen within the last 5 years were included. Non-screened patients who visited or could be recalled to the clinics over a 6-month period were prospectively tested for anti-HDV. RESULTS: Of 5079 HBsAg-positive patients, 53% had anti-HDV screening (41% before and 12% after study initiation). Pre-study (8%-88%) and total screening rates (14%-100%) varied widely among centres. Screening rates were associated with older age, known risk group, elevated ALT, centre location and size and period of first visit. Anti-HDV prevalence was 5.8% without significant difference in patients screened before (6.1%) or after study initiation (4.7%, p = 0.240). Anti-HDV positivity was associated with younger age, parenteral drug use, born abroad, advanced liver disease and centre location. Overall, HDV RNA detectability rate was 71.6% being more frequent in anti-HDV-positive patients with elevated ALT, advanced liver disease and hepatitis B therapy. CONCLUSIONS: Anti-HDV screening rates and recall capabilities vary widely among Greek liver clinics being higher in HBsAg-positive patients of known risk group with active/advanced liver disease seen at smaller centres, while non-medical factors are also important. Anti-HDV prevalence varies throughout Greece being higher in patients born abroad with younger age, parenteral drug use and advanced liver disease. Viremia is more frequently but not exclusively detected in anti-HDV-positive patients with elevated ALT and advanced liver disease.

High levels of all-cause mortality among people who inject drugs from 2018 to 2022.

BACKGROUND: Mortality among people who inject drugs (PWID) is high, with overdose and HIV infection being the main causes of death. In Greece, there have been no data on mortality, and two HIV outbreaks have been recorded in this population in the past decade. In this study, we aim to estimate the all-cause crude mortality rate and the standardised mortality ratio in this population during 2018-2022. METHODS: PWID recruited from two community-based programs in Athens and Thessaloniki during 2018-2021 were interviewed and tested for HIV/HCV. Data on vital status (deceased/alive) and date of death were obtained from death registries through December 31, 2022. All-cause crude mortality rates (CMR) and standardised mortality ratios (SMR) were estimated. Determinants of mortality were assessed using Cox proportional-hazards model. RESULTS: Of 2,530 participants, 301 died over 8,543 person-years (PYs) of follow-up. The CMR (95 % CI) was 3.52 (3.15-3.94) deaths per 100 PYs; 3.10 per 100 PYs (2.68-3.58) in Athens and 4.48 per 100 PYs (3.74-5.37) in Thessaloniki. An increasing trend in CMR was identified over 2018-2022 in Athens (from 2.90 to 4.11 per 100 PYs, 41.5 % increase, p = 0.018). The pooled SMR (95 % CI) was 15.86 (14.17-17.76) for both cities and was particularly increased in younger individuals, females, those injecting daily, not enrolled to opioid agonist treatment and HIV-infected individuals. Older age, living in Thessaloniki, Greek origin, homelessness, history of injection in the past 12 months, and HIV infection were independently associated with higher risk of death. CONCLUSION: Mortality among PWID in the two largest cities (Athens and Thessaloniki) in Greece in 2018-2022 was high, with the population in Thessaloniki being particularly affected. The increasing trend in mortality in Athens may reflect the long-term impact of the COVID-19 pandemic. Preventive programs such as take-home naloxone, screening and treatment for HIV, are urgently needed.

Spontaneous bacterial peritonitis: a prospective Greek multicenter study of its epidemiology, microbiology, and outcomes.

BACKGROUND: Spontaneous bacterial peritonitis (SBP) is an ominous complication of decompensated cirrhosis. This study aimed to assess several epidemiological, clinical, microbiological and outcome characteristics in Greek patients with SBP, as no solid representative nationwide data of this type was available. METHODS: During a 3-year period, 77 consecutive patients with SBP (61 male; median age: 67 years; model for end-stage liver disease [MELD] score: 20), diagnosed and followed in 5 tertiary liver units, were prospectively recruited and studied. Various prognostic factors for disease outcome were studied. RESULTS: Thirty-eight patients had alcohol-related cirrhosis, 17 viral hepatitis, 6 non-alcoholic steatohepatitis, 6 autoimmune liver diseases, and 10 cryptogenic cirrhosis. Hepatocellular carcinoma (HCC) was present in 23 (29.9%), whereas 10 (13%) had portal vein thrombosis. The first SBP episode at baseline was community-acquired in 53 (68.8%), while in 24 (31.1%) was hospital-acquired, with predominant symptoms abdominal pain and encephalopathy. A positive ascitic culture was documented in 36% of patients in the initial episode, with almost equal gram (+) and gram (-) pathogens, including 3 multidrug-resistant pathogens. Significant factors for 6-month survival were: higher MELD score, previous b-blocker use, lower serum albumin, higher lactate on admission and need for vasopressors, while factors for 12-month survival were MELD score and lactate. For overall survival, higher MELD score and lactate along with HCC presence were negative predictive factors. CONCLUSIONS: MELD score, lactate, albumin, HCC and treatment with vasopressors were predictive of survival in SBP patients. In hospital-acquired SBP the prevalence of difficult-to-treat pathogens was higher.

Long-term adefovir plus lamivudine therapy does not decrease creatinine clearance in HBeAg-negative chronic hepatitis B patients.

BACKGROUND/AIMS: As there are concerns about potential nephrotoxicity of nucleotide analogues, we evaluated renal function parameters during long-term adefovir and lamivudine combination therapy. METHODS: Forty-six HBeAg-negative patients with lamivudine-resistance treated with adefovir and lamivudine for up to 90 months were included. Renal function was assessed by estimated creatinine clearance (eC(CR) ) and compared with a matched control group of untreated inactive hepatitis B virus carriers. RESULTS: Serum HBV DNA became undetectable in 39 (85%) patients after a mean of 37 ± 21 months. Three (6.5%) patients developed virological breakthrough. Adefovir resistance was detected in two patients. At the end of follow up, there was a significant decrease in mean eC(CR) (95 ± 31-83 ± 30 ml/min, P = 0.003) in the treated patients with 16% presenting aeC(CR) decrease >30%. Similar changes in eC(CR) were observed in the control group (108 ± 28-96 ± 26 ml/min, P = 0.003). In multiple regression analysis, age and baseline eC(CR) were independent predictors of eC(CR) reduction. CONCLUSIONS: Adefovir and lamivudine combination therapy is not an independent factor for significant renal dysfunction in HBeAg-negative patients with lamivudine-resistance. Baseline age and creatinine clearance are the only independent predictors of worsening renal function.

Differences between fellows and fellowship program directors in their perception of the impact of the COVID-19 pandemic on gastroenterology training: results from a nationwide survey in Greece.

BACKGROUND: Lockdown measures applied during the SARS-CoV-2 outbreak caused a significant disturbance to hospital routine. We assessed trainees' and fellowship directors' perceptions regarding the impact of the pandemic on gastroenterology fellowship training. METHODS: A web-based survey was anonymously disseminated to all Greek gastroenterology fellows and fellowship program directors. Participants completed electronically a questionnaire comprised of 5 domains that assessed participants' perception of: 1) overall impact on training; 2) impact on training in gastroenterology-specific fields (endoscopy, inflammatory bowel disease, hepatology); 3) impact on different aspects of endoscopy training; 4) impact on academic training; and 5) training perspectives for the post-pandemic era. RESULTS: A total of 77/128 fellows (60.1%) and 18/28 fellowship program directors (64.3%) responded. More fellows reported that the COVID-19 pandemic would have an adverse impact on fellowship training compared to their fellowship program directors (81.8% vs. 55.6%, P=0.038). This concern was mainly focused on endoscopy training (83.1% vs. 27.8%, P<0.001), with no difference regarding training in gastroenterology's other specific fields. The difference was consistent for technical skills (79.2% vs. 38.9%, P=0.001), and for the performance of basic diagnostic (70.1% vs. 22.2%, P<0.001) and emergency (48.1% vs. 11.1%, P=0.004) procedures. Fellows and fellowship program directors identified the unknown timeframe of measure implementation and the postponement of scheduled endoscopic procedures as the main factors that negatively affected training. Extension of the fellowship training program was deemed the optimal option by fellows for addressing the training decrement in the post-pandemic era, while fellowship program directors favored an increase in workload. CONCLUSION: Fellows and their fellowship program directors do not share the same concerns about the impact of COVID-19 pandemic on training programs and they propose different measures to remedy its effects.

Epidemiology of Hematologic Malignancies in Real-World Settings: Findings From the Hemato-Oncology Latin America Observational Registry Study.

PURPOSE: Limited information is available on multiple myeloma (MM), chronic lymphocytic leukemia (CLL), and non-Hodgkin lymphoma (NHL) management in Latin America. The primary objective of the Hemato-Oncology Latin America (HOLA) study was to describe patient characteristics and treatment patterns of Latin American patients with MM, CLL, and NHL. METHODS: This study was a multicenter, retrospective, medical chart review of patients with MM, CLL, and NHL in Latin America identified between January 1, 2006, and December 31, 2015. Included were adults with at least 1 year of follow-up (except in cases of death within 1 year of diagnosis) treated at 30 oncology hospitals (Argentina, 5; Brazil, 9; Chile, 1; Colombia, 5; Mexico, 6; Panama/Guatemala, 4). RESULTS: Of 5,140 patients, 2,967 (57.7%) had NHL, 1,518 (29.5%) MM, and 655 (12.7%) CLL. Median follow-up was 2.2 years for MM, 3.0 years for CLL, and 2.2 years for NHL, and approximately 26% died during the study observation period. Most patients had at least one comorbidity at diagnosis. The most frequent induction regimen was thalidomide-based chemotherapy for MM and chlorambucil with or without prednisone for CLL. Most patients with NHL had diffuse large B-cell lymphoma (DLBCL; 49.1%) or follicular lymphoma (FL; 19.5%). The majority of patients with DLBCL or FL received rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone. CONCLUSION: The HOLA study generated an unprecedented level of high-quality, real-world evidence on characteristics and treatment patterns of patients with hematologic malignancies. Regional disparities in patient characteristics may reflect differences in ethnoracial identity and level of access to care. These data provide needed real-world evidence to understand the disease landscape in Latin America and may be used to inform clinical and health policy decision making.

Plasma oxysterols in normal and cholestatic children as indicators of the two pathways of bile acid synthesis.

BACKGROUND: No information is available on the hepatic and extrahepatic pathways of bile acid synthesis in normal children and in pediatric cholestatic liver diseases. METHODS: To explore the changes of the two pathways of bile acid synthesis during development, plasma concentrations of 7alpha-hydroxycholesterol and 27-hydroxycholesterol were measured in 50 healthy children (1 month-14 years) and compared to 18 adult controls. We also measured plasma oxysterols in 31 patients with pediatric cholestatic liver disease. RESULTS: A progressive increase of plasma concentrations of both 27-hydroxycholesterol and 7alpha-hydroxycholesterol was found with age. In children with cystic fibrosis-associated liver disease plasma concentrations of 27-hydroxycholesterol were significantly lower compared to age-matched controls (5.6+/-0.5 vs. 12.8+/-1.1 microg/dl; p<0.001) and paralleled significantly lower concentrations of total cholesterol. In infants with biliary atresia plasma concentrations of 27-hydroxycholesterol were significantly higher compared to age-matched controls (8.8+/-0.8 vs. 4.4+/-0.6 microg/dl, p<0.001) paralleling significantly higher concentrations of total cholesterol while 7alpha-hydroxycholesterol resulted significantly lower (1.2+/-0.2 vs. 2.3+/-0.3 microg/100 mg of total cholesterol; p=0.011). CONCLUSIONS: Our data suggest that both pathways of bile acid synthesis reach a state of maturity only after the age of 4 years and are significantly influenced also in children by liver function and intestinal absorption of cholesterol.

Successful prevention of multidrug resistant HIV mother-to-child transmission with enfuvirtide use in late pregnancy.

The availability of antiretroviral therapy has dramatically reduced the risk of HIV mother-to-child transmission (MTCT). However, mothers infected with multidrug resistant HIV (MDR-HIV) are at increased risk of MTCT. We report the case of a pregnant patient infected with MDR-HIV in whom MTCT was avoided with enfuvirtide use in late pregnancy and elective caesarean section.

Clinical and epidemiological characteristics of hepatitis C virus-infected people who inject drugs: a Greek descriptive analysis.

BACKGROUND: It is estimated that 17,000 people who inject drugs (PWID) in Greece have hepatitis C virus (HCV) viremia. The aim of our study was to explore the characteristics of the HCV-infected, direct acting antiviral (DAA)-naïve PWID. METHODS: This is a retrospective analysis of PWID with HCV infection. We selected data from six liver clinics during the period from 1st May 2014 to 31st May 2017 in order to record the characteristics of infected PWID. RESULTS: We included 800 PWID with HCV infection (78.5% male, mean age 42±10 years) who had not received DAAs before 1st June 2017. One third of the patients had comorbidities (diabetes mellitus, arterial hypertension and psychological disorders); 70% were smokers, 27% alcohol users, 67% unemployed, 29% married, and 34% had education >12 years; 65% were attending addiction programs; 57% were receiving methadone and 36% buprenorphine. Sporadic or systemic drug use was reported by 37% while 1.4% and 2.9% had HIV and HBV coinfection, respectively. The genotype distribution was 20.5%, 4.6%, 3.3%, 61% and 10% for genotypes 1a, 1b, 2, 3 and 4, respectively. Mean (±SD) liver stiffness was 9±7 kPa and 21% of the patients had cirrhosis. Half of the patients were in the F0-F1 stage of liver disease, defined as stiffness ≤7 kPa. CONCLUSIONS: Our real-life data suggest that HCV genotype 3 remains the predominant genotype among PWID. One third of PWID had comorbidities and one-fifth cirrhosis. Half of PWID had early-stage liver disease and remained without access to DAAs according to the Greek prioritization criteria.

Eosinophilic Cholangitis--A Challenging Diagnosis of Benign Biliary Stricture: A Case Report.

When confronting a biliary stricture, both benign and malignant etiologies must be carefully considered as a variety of benign biliary strictures can masquerade as hilar cholangiocarcinoma (CCA). Therefore, patients could undergo a major surgery despite the possibility of a benign biliary disease. Approximately 15% to 24% of patients undergoing surgical resection for suspected biliary malignancy will have benign pathology. Eosinophilic cholangitis (EC) is a rare benign disorder of the biliary tract, which can cause obstructive jaundice and can pose a difficult diagnostic task. We present a rare case of a young woman who was referred to our hospital with obstructive painless jaundice due to a biliary stricture at the confluence of the hepatic bile ducts, with a provisional diagnosis of cholangiocarcinoma. Though, during her work up she was found to have EC, an extremely rare benign cause of biliary stricture, which is characterized by a dense eosinophilic infiltration of the biliary tree causing stricturing, fibrosis, and obstruction and which is reversible with short-term high-dose steroids. Despite its rarity, EC should be taken into consideration when imaging modalities demonstrate a biliary stricture, especially if preoperative diagnosis of malignancy cannot be made, in the setting of peripheral eosinophilia and the absence of cardinal symptoms of malignancy.

Assessment of blood coagulation in severe liver disease using thromboelastography: use of citrate storage versus native blood.

Thromboelastography evaluates the viscoelastic properties of blood coagulation. Using native blood, measurement must start soon after sampling. With normal coagulation, native and citrated blood values correlate well. No data exists from cirrhotic patients. We compared native and citrate thromboelastography parameters in 30 cirrhotic patients (20 Child-Pugh C class, two liver failure). Thromboelastography was performed within 4 min using native blood and after recalcification within 1-2 h of citrate storage. Thromboelastography variables (, alpha, ) were compared using the Mann-Whitney test, correlation investigated with the Pearson method and the degree of agreement with the Bland-Altman method. There was no significant difference between citrated and native blood for all variables. Median values for native and citrated were, respectively, 16.4 (range 2.3-22.5) and 15.1 (range 9.8-29.9); 6.3 (range 3.5-11.3) and 6.2 (range 2.8-10.9); 48.3 (range 30.7-62.9) and 46.2 (range 30.4-60.4); angle alpha 30.8 (range 18.7-46.8) and 33.2 (range 19.9-55.8). Correlation for each variable was significant ( 0.01). There was a good degree of agreement for all but two patients (both bleeding) for all variables. Citrated blood can substitute native blood using thromboelastography in cirrhotic patients, allowing more time between sampling and the thromboelastography measurement.

Drug treatment for portal hypertension.

Pharmacological treatment of portal hypertension has played an increasing clinical role in the past 20 years. In the setting of acute variceal bleeding, drug therapy should be considered the initial treatment of choice and can be administered as soon as possible; even during the transfer of the patient to hospital. Several recent trials have reported similar efficacy to emergency sclerotherapy, therefore drug treatment should no longer be considered as a "stop gap" therapy until definitive endoscopic therapy is performed but continued for several days. Antibiotic prophylaxis is an integral part of therapy as it reduces mortality and should be instituted from admission. Non selective b-blockers are the treatment of first choice for secondary and primary prevention. If they are contraindicated or non tolerated banding ligation can be used. There is less evidence for the benefit of ligation for primary prophylaxis. The use of haemodynamic targets for reduction in hepatic venous pressure gradient response need further study, and surrogate markers of pressure response need evaluation

Frequency and predictors of no treatment in anti-hepatitis C virus-positive patients at tertiary liver centers in Greece.

BACKGROUND/AIMS: Despite the improving efficacy of antiviral therapy, a significant proportion of chronic hepatitis C patients never start treatment. We determined the magnitude and reasons for no treatment in anti-hepatitis C virus (HCV)-positive patients visiting tertiary liver centers in Greece. MATERIALS AND METHODS: We retrospectively enrolled 1146 consecutive anti-HCV-positive patients who visited four physicians at two tertiary liver centers between 2002 and 2010. RESULTS: Treatment was initiated in 628 (55%) of the 1146 patients. In particular, 309 (27%) patients were lost to follow-up before HCV RNA testing. Independent predictors of no HCV RNA testing were first visit before 2007, parenteral drug use, and the treating physician. Of the 837 patients tested for HCV RNA, 768 (92%) were eligible for antiviral therapy, had detectable serum HCV RNA, and no contraindication to treatment. Among them, 140 (18%) patients were lost to follow-up before the initiation of treatment or refused antiviral therapy. Independent predictors of no treatment were the treating physician, absence of liver biopsy or transient elastography (odds ratio: 3.5, 95% confidence interval: 2.3-5.4, P<0.001), and normal compared with elevated alanine transaminase levels (odds ratio: 1.7, 95% confidence interval: 1.1-2.8, P=0.027). CONCLUSION: A significant proportion (>40%) of anti-HCV-positive patients visiting Greek tertiary liver centers do not receive antiviral therapy. Most of them are lost during the initial evaluation process, whereas the majority (>80%) of eligible patients who complete the initial evaluation eventually start antiviral therapy. The probability of treatment seems to be significantly associated with the treating physician, the alanine transaminase levels, and whether liver biopsy or transient elastography was performed.

Hepatic venous pressure gradient to assess fibrosis and its progression after liver transplantation for HCV cirrhosis.

Progression of fibrosis following recurrent hepatitis C virus (HCV) infection is frequent after liver transplantation (LT). Histology remains the gold standard to assess fibrosis, but the value of hepatic venous pressure gradient (HVPG) is being explored. We evaluated patients with recurrent HCV infection after LT to assess whether HVPG correlates with liver histology, particularly fibrosis. A total of 90 consecutive patients underwent 170 HVPG measurements concomitant with transjugular liver biopsy (TJB), with 31.5 (range, 6-156) months of follow up. Median biopsy length was 22 mm and total portal tract count was 12 (complete 6, partial 6). Median HVPG was 4 mmHg: 38% of patients > or =6 mmHg (portal hypertension, PHT), 13% > or =10 mmHg. HVPG correlated with Ishak stage (r = 0.73, P < 0.001) for mild (0-3) and severe fibrosis (4-6), and grade score (r = 0.47, P < 0.001), but neither correlated with interval from LT nor biopsy length. HVPG was > or =10 mmHg in 15 patients: 12 had stage 5 or 6, and 3 severe portal expansion. HVPG was repeated in 49, between 7 and 60 months with weak correlation to fibrosis score (r = 0.30, P = 0.045). A total of 12 patients with HVPG > or =6 mmHg had fibrosis score < or =3, while 8 patients had normal HVPG but fibrosis stage > or =4. These discrepancies were mostly associated with specific histological features such as perisinusoidal fibrosis rather than errors in measuring HVPG. In 29 with HVPG <6 mmHg at 1 yr, none decompensated compared to 4 of 13 (31%) with PHT. In conclusion, HVPG correlates with fibrosis and its progression, due to recurrent HCV infection, assessed in TJB.

Targeting portal pressure measurements: a critical reappraisal.

Many of the complications of cirrhosis reflect the presence of portal hypertension, which is commonly expressed as the hepatic venous pressure gradient (HVPG). Baseline and repeat measurements of HVPG have been recommended for the management of patients with cirrhosis in the setting of pharmacologic prophylaxis of variceal bleeding and for gaining information about prognosis. However, published studies have demonstrated problems with the interpretation of the data on HVPG monitoring, making its use controversial. We view the current data as insufficient evidence to support the monitoring of a targeted reduction of HVPG as routine clinical practice. We recommend the performance of new prospective studies to establish the clinical importance of HVPG measurements.

Quistes de epiplón y mesenterio en niños; revisión de 10 años / Omentum cysts and mesentery cysts in children. A 10 years review

Se revisan los casos de niños operados con diagnóstico de quiste de epiplón (QE) y mesenterio (QM) en el período de Agosto 2003 a Agosto 2013, en el Hospital Dr. Gustavo Fricke de Viña del Mar. Estos son quistes intraabdominales de escasa frecuencia, que evolucionan como tumoración asintomática, pudiendo presentar diversas manifestaciones clínicas desde constipación, vómitos y dolor hasta ser causa de abdomen agudo en el niño. La radiografía de abdomen simple y el ultrasonido pueden ser de utilidad para plantear la sospecha diagnostica, siendo la tomografía computada el estudio de excelencia en estos casos. Se encontró tres pacientes, dos QE y un QM. Los motivos de consulta fueron: masas abdominal (QE), dolor abdominal recurrente (QM) y abdomen agudo (QM). El diagnóstico se confirmó con TAC y se realizo exéresis total de la lesión en todos los casos. En un paciente fue necesaria la resección intestinal complementaria (QM). No hubo complicaciones en nuestros casos.

This is a case review of operated children with diagnosis of omentum cysts (OC) or mesentery cysts (MC), since August 2003 to August 2013 at Dr. Gustavo Fricke Hospital, Viña del Mar, Chile. These are rare intraabdominal lesions that frequently evolve as an asymptomatic tumor; clinical manifestations are constipation, vomits, abdominal pain and occasionally may be cause of acute abdomen in the child. The abdominal radiography and ultrasound may be useful, but the abdominal pelvic CT scan is the gold standard in these affections. Three cases were found, two OC and one MC. Symptoms were: abdominal tumor (OC), recurrent abdominal pain (OC) and acute abdomen (MC). Diagnosis confirmation was made with TC scan in all cases. Total exeresis of the benign tumor lesion was performed in all cases. In one patient it was necessary to perform intestinal resection for the tumor exeresis (MC). There were no complications.

TIPS for acute and chronic Budd-Chiari syndrome: a single-centre experience.

BACKGROUND/AIMS: Transjugular intrahepatic portosystemic shunt (TIPS) is a technically challenging but feasible treatment for Budd-Chiari syndrome (BCS). However, information about the outcome, particularly in patients with liver failure, is scarce. We report our experience of TIPS for BCS. METHODS: Fifteen patients with BCS underwent TIPS. Eight had hepatic failure and seven underwent TIPS for BCS uncontrolled by medical treatment. RESULTS: Fourteen out of 15 had successful TIPS placement. Out of the eight hepatic failure patients, four died soon after TIPS: one liver rupture, one portal vein rupture, one liver failure and one pulmonary oedema. Another patient had a significant intrahepatic haematoma, which resolved with conservative management. TIPS was successfully placed in all of the seven patients with chronic BCS, in whom there was an average follow-up of 20 months. Ascites resolved and liver function improved in all. One patient died after 18 months from the original hepatic metastatic disease. Four patients have had evidence of TIPS dysfunction requiring three balloon dilatations and one restenting. No patient has required liver transplantation. CONCLUSIONS: TIPS should be the first line treatment for BCS uncontrolled by medical therapy. However, mortality in BCS with hepatic failure is high and liver transplantation could be a better option.
