RESUMO

BACKGROUND: Management of portal hypertensive colopathy (PHC) has been challenged by controversial results in its prevalence and clinical relevance. OBJECTIVE: To describe the PHC prevalence and to evaluate the variability in diagnosis, the relation to severity of liver disease, and the incidence of severe outcomes. DESIGN: Cross-sectional study. SETTING: Endoscopic unit of a tertiary-care academic center in Rio de Janeiro, Brazil. PATIENTS: Patients with cirrhosis with portal hypertension and controls paired for age and sex. INTERVENTIONS: All patients were submitted to standard and image-enhanced colonoscopies, which were recorded in a coded video file and analyzed twice by a blinded endoscopist. MAIN OUTCOME MEASUREMENTS: The prevalence of PHC. RESULTS: A total of 51 patients with cirrhosis (55% male, mean age 59 years) and 51 healthy controls (43% male, mean age 61 years) were included. The top ranking colonoscopic findings were angiodysplasia-like lesions, nonspecific vascular pattern, red spots, and colorectal varices, all significantly more frequent in patients with cirrhosis compared with controls. PHC prevalence was 71% in patients with cirrhosis. For PHC, interobserver and intraobserver agreement (k values [standard error]) were 0.68 (0.09) and 0.63 (0.10), respectively. Intraobserver agreement for colonoscopic findings was satisfactory. PHC was not related to more severe liver disease or liver stiffness. Only 5 patients developed severe outcomes during follow-up. LIMITATIONS: The exclusion of patients with cirrhosis without esophageal varices and the absence of an interobserver agreement analysis by double-blinded endoscopists. CONCLUSION: PHC was highly prevalent in patients with cirrhosis, and its diagnostic agreement was satisfactory. PHC is not associated with relevant severe outcomes in a 12-month follow-up.

RESUMO

OBJECTIVE: Although endoscopic ultrasonography-guided fine needle aspiration (EUS-FNA) is the gold standard for diagnosing pancreatic lesions, its negative predictive value is suboptimal. Our aim was to evaluate the yield of contrast-enhanced EUS (CED-EUS) and of strain ratio EUS-elastography (SR-E-EUS) for differentiating pancreatic solid lesions. METHODS: Forty-seven patients (27 men, 20 women, 70 ± 11 years) were consecutively involved in this single-center, prospective study. They were submitted to EUS, SR-E-EUS, CED-EUS with Sonovue(®), and EUS-FNA. The final diagnosis was based on the histological assessment of EUS-FNA and/or surgical specimens when available, and on follow-up of at least 6 months. RESULTS: From the 47 focal pancreatic lesions included, 13 (28%) were benign and 34 (72%) malignant. Patients with malignancy were older (70 ± 11 vs. 61 ± 8, P = 0.003), and had larger lesions (34 ± 12 mm vs. 22 ± 11 mm, P = 0.03). Malignant lesions had higher SR-E-EUS (31 ± 32 vs. 8 ± 9, P = 0.001) and more hypovascular pattern (93% vs. 33%, P < 0.001). Logistic regression determined that only hypovascularity (OR = 2.6, 95%CI: 1.5-130, P = 0.02) was independently predictive of malignancy. ROC analysis for SR-E-EUS yielded an optimal cutoff of 8 (AUC 0.91, 95%CI: 0.74-0.98) for the best power distinction for malignancy. There was no significant difference concerning sensitivity (79%, 90%, 93%) and specificity rates (85%, 75%, 67%) of EUS-FNA, SR-E-EUS, and CED-EUS, respectively. By analysis of the inconclusive EUS-FNA subset (9 patients, 19%), SR-E-EUS > 8 and hypovascularity showed sensitivity of 80% and 100%, and specificity of 67% and 67%, respectively. CONCLUSION: The clinical utility of CED-EUS and SR-E-EUS remains questionable. The accuracies of CED-EUS and SR-E-EUS are similar to EUS-FNA. Hypovascularity was independently predictive of malignancy. Patients with inconclusive EUS-FNA could benefit from CED-EUS due to the high sensitivity of hypovascularity for diagnosing malignancy.

RESUMO

PURPOSE: To evaluate the success and complication rates of early precut papillotomy in difficult biliary cannulations performed by an average endoscopist skilled in ERCP. METHODS: We studied 146 consecutive ERCPs during a 27-month period. Precutting was instituted if cannulation failed after 10-15 min. Standard papillotomy was performed in the rest. The analysis was divided into initial period (1st year) and subsequent period (following 15 months). RESULTS: The success rate of cannulation was 95% (139/146). Standard papillotomy was performed in 103/146 (71%) patients. In the remainder, cannulation was successful after precutting in 36/43 (84%) patients. The complication rate was 10% (8/103 in the standard vs. 7/43 in the precut group, P = 0.14). All complications of the standard group were mild. In the precut group, there were three moderate to severe complications. There were no differences between the two periods. CONCLUSIONS: Precut papillotomy can be an effective and relatively safe procedure when performed by an average endoscopist skilled in ERCP. Although the complication rate of precutting tended to be higher than standard papilotomy, this was reasonable since it increased the success of selective biliary cannulation in 25% of cases. Complication rates did not improve with experience.

RESUMO

BACKGROUND: Liver cirrhosis affects the results of many of the traditional techniques currently used to evaluate nutritional status. Our aim was to compare the traditional two-compartment model (subjective global assessment and anthropometry and blood tests) of nutritional assessment with a multicompartmental model (body composition analysis) in patients with cirrhosis. METHODS: Seventy-nine patients and 17 control subjects were studied. Subjective global assessment, anthropometry and blood tests, and body composition analysis were performed for each. The two most important compartments were body cell mass and total body fat. The subjects were classified by each method as well nourished or moderately or severely malnourished. RESULTS: Twenty-five patients (31.6%) were malnourished according to the subjective global assessment, 2 (6.3%) with Child's class A cirrhosis, 10 (34.5%) with class B, and 13 (72.2%) with class C, whereas 24 (30.4%) were malnourished according to the traditional model, 5 (15.6%) in the Child's A group, 8 (27.6%) in B, and 11 (61.1%) in C. According to the multicompartmental model, 48 patients (60.1%) were malnourished, 11 (34.4%) in Child's A, 20 (69%) in B, and 17 (94.4%) in C. The use of the multicompartmental model increased the prevalence of malnutrition by more than 60% in Child's classes A and B patients and by more than 20% in Child's class C patients. CONCLUSIONS: Traditional nutritional assessment, although easier, underestimated the prevalence and severity of malnutrition in patients with cirrhosis. The underestimation was more pronounced in Child's class A and B patients.

RESUMO

Strongyloides stercoralis é um nematódeo intestinal que, usualmente, causa infecçäo intestinal limitada e assintomática em indivíduos saudáveis. Pode, eventualmente, tornar-se uma infecçäo disseminada e fatal em pacientes imunossuprimidos, Neste artigo, descrevemos um caso incomum de estrongiloidíase disseminada com manifestaçöes cutâneas, intestinais, neurológicas, pulmonares e infecciosas em um paciente usuário de corticosteróides
