| 1 | Acute calculous cholecystitis: Review of current best practices显示文摘Acute calculous cholecystitis(ACC) is the most frequent complication of cholelithiasis and represents one-third of all surgical emergency hospital admissions, many aspects of the disease are still a matter of debate. Knowledge of the current evidence may allow the surgical team to develop practical bedside decision-making strategies, aiming at a less demanding procedure and lower frequency of complications. In this regard, recommendations on the diagnosis supported by specific criteria and severity scores are being implemented, to prioritize patients eligible for urgency surgery. Laparoscopic cholecystectomy is the best treatment for ACC and the procedure should ideally be performed within 72h. Early surgery is associated with better results in comparison to delayed surgery. In addition, when to suspect associated common bile duct stones and how to treat them when found are still debated. The antimicrobial agents are indicated for high-risk patients and especially in the presence of gallbladder necrosis. The use of broad-spectrum antibiotics and in some cases with antifungal agents is related to better prognosis. Moreover, an emerging strategy of not converting to open, a difficult laparoscopic cholecystectomy and performing a subtotal cholecystectomy is recommended by adept surgical teams. Some authors support the use of percutaneous cholecystostomy as an alternative emergency treatment for acute Cholecystitis for patients with severe comorbidities. | Carlos Augusto Gomes Cleber Soares Junior Salomone Di Saveiro Massimo Sartelli Michel Denis Kelly Camila Couto Gomes Felipe Couto Gomes Lívia Dornellas Correa Camila Brandao Alves Samuel de Fádel Guimaraes | 2017 | World Journal of Gastrointestinal Surgery2017，9，5： | 18 |
| 2 | Embolization of splenorenal shunt associated to portal vein thrombosis and hepatic encephalopathy显示文摘Hepatic encephalopathy(HE)is a cognitive disturbance characterized by neuropsychiatric alterations.It occurs in acute and chronic hepatic disease and also in patients with portosystemic shunts.The presence of these portosystemic shunts allows the passage of nitrogenous substances from the intestines through systemic veins without liver depuration.Therefore,the embolization of these shunts has been performed tocontrol HE manifestations,but the presence of portal vein thrombosis is considered a contraindication.In this presentation we show a cirrhotic patient with severe HE and portal vein thrombosis who was submitted to embolization of a large portosystemic shunt.Case report:a 57 years-old cirrhotic patient who had been hospitalized many times for persistent HE and hepatic coma,even without precipitant factors.She had a wide portosystemic shunt and also portal vein thrombosis.The abdominal angiography confirmed the splenorenal shunt and showed other shunts.The larger shunt was embolized through placement of microcoils,and the patient had no recurrence of overt HE.There was a little increase of esophageal and gastric varices,but no endoscopic treatment was needed.Since portosystemic shunts are frequent causes of recurrent HE in cirrhotic patients,portal vein thrombosis should be considered a relative contraindication to perform a shunt embolization.However,in particular cases with many shunts and severe HE,we found that one of these shunts can be safely embolized and this procedure can be sufficient to obtain a good HE recovery.In conclusion,we reported a case of persistent HE due to a wide portosystemic shunt associated with portal vein thrombosis.As the patient had other shunts,she was successfully treated by embolization of the larger shunt. | Letícia de Campos Franzoni Fábio Cardoso de Carvalho Rafael Gomes de Almeida Garzon Fábio da Silva Yamashiro Laís Augusti Lívia Alves Amaral Santos Mariana de Souza Dorna Júlio Pinheiro Baima Talles Bazeia Lima Carlos Antonio Caramori Giovanni Faria Silva Fernando Gomes Romeiro | 2014 | World Journal of Gastroenterology2014，20，42： | 6 |
| 3 | High prevalence of vitamin A deficiency in Crohn's disease patients according to serum retinol levels and the relative dose-response test显示文摘AIM:To assess the vitamin A status of patients with Crohn's disease(CD) by evaluating serum retinol levels and the relative dose response(RDR) test(liver retinol stores).METHODS:Vitamin A nutritional status was measured by serum retinol obtained by high performance liquid chromatography and the RDR test for evaluation of the hepatic stores.Body composition was performed by densitometry by dual-energy X-ray absorptiometry.Vitamin A dietary intake was assessed from a semiquantitative food frequency questionnaire.RESULTS:This study included 38 CD patients and 33 controls.Low serum retinol concentrations were detected in 29% of CD patients vs 15% in controls(P < 0.005).The RDR test was positive in 37% of CD patients vs 12% in controls,which indicated inadequate hepatic vitamin A stores(P < 0.005).Individuals with hypovitaminosis A had lower BMI and body fat compared with those without this deficiency.There was no association between vitamin A deficiency and its dietary intake,ileal location,presence of disease activity and prior bowel resections.CONCLUSION:Patients with CD have higher prevalence of vitamin A deficiency,as assessed by two independent methods. | Márcia Soares-Mota Tianny A Silva Luanda M Gomes Marco AS Pinto Laura MC Mendon?a Maria Lúcia F Farias Tiago Nunes Andrea Ramalho Cyrla Zaltman | 2015 | World Journal of Gastroenterology2015，21，5： | 4 |
| 4 | Quality of life, work productivity impairment and healthcare resources in inflammatory bowel diseases in Brazil显示文摘BACKGROUND Inflammatory bowel diseases(IBD)have been associated with a low quality of life(QoL)and a negative impact on work productivity compared to the general population.Information about disease control,patient-reported outcomes(PROs),treatment patterns and use of healthcare resources is relevant to optimizing IBD management.AIM To describe QoL and work productivity and activity impairment(WPAI),treatment patterns and use of healthcare resources among IBD patients in Brazil.METHODS A multicenter cross-sectional study included adult outpatients who were previously diagnosed with moderate to severe Crohn’s disease(CD)or ulcerative colitis(UC).At enrolment,active CD and UC were defined as having a Harvey Bradshaw Index≥8 or a CD Activity Index≥220 or calprotectin>200μg/g or previous colonoscopy results suggestive of inadequate control(per investigator criteria)and a 9-point partial Mayo score≥5,respectively.The PRO assessment included the QoL questionnaires SF-36 and EQ-5D-5L,the Inflammatory Bowel Disease Questionnaire(IBDQ),and the WPAI questionnaire.Information about healthcare resources and treatment during the previous 3 years was collected from medical records.Chi-square,Fisher’s exact and Student’s t-/Mann-Whitney U tests were used to compare PROs,treatment patterns and the use of healthcare resources by disease activity(α=0.05).RESULTS Of the 407 patients in this study(CD/UC:64.9%/35.1%,mean age 42.9/45.9 years,54.2%/56.6%female,38.3%/37.1%employed),44.7%/25.2%presented moderate-to-severe CD/UC activity,respectively,at baseline.Expressed in median values for CD/UC,respectively,the SF-36 physical component was 46.6/44.7 and the mental component was 45.2/44.2,the EQ-visual analog scale score was 80.0/70.0,and the IBDQ overall score was 164.0/165.0.Moderate to severe activity,female gender,being unemployed,a lower educational level and lower income were associated with lower QoL(P<0.05).Median work productivity impairment was 20%and 5%for CD and UC patients,respectively,and activity impairment was 30%,the latter being higher among patients with moderate to severe disease activity compared to patients with mild or no disease activity(75.0%vs 10.0%,P<0.001).For CD/UC patients,respectively,25.4%/2.8%had at least one surgery,38.3%/19.6%were hospitalized,and 70.7%/77.6%changed IBD treatment at least once during the last 3 years.The most common treatments at baseline were biologics(75.3%)and immunosuppressants(70.9%)for CD patients and 5-ASA compounds(77.5%)for UC patients.CONCLUSION Moderate to severe IBD activity,especially among CD patients,is associated with a substantial impact on QoL,work productivity impairment and an increased number of IBD surgeries and hospitalizations in Brazil. | Rogerio Serafim Parra Julio MF Chebli Heda MBS Amarante Cristina Flores Jose ML Parente Odery Ramos Milene Fernandes Jose JR Rocha Marley R Feitosa Omar Feres Antonio S Scotton Rodrigo B Nones Murilo M Lima Cyrla Zaltman Carolina D Goncalves Isabella M Guimaraes Genoile O Santana Ligia Y Sassaki Rogerio S Hossne Mauro Bafutto Roberto LK Junior Mikaell AG Faria Sender J Miszputen Tarcia NF Gomes Wilson R Catapani Anderson A Faria Stella CS Souza Rosana F Caratin Juliana T Senra Maria LA Ferrari | 2019 | World Journal of Gastroenterology2019，25，38： | 2 |
