Portal blood flow volume measurement in schistosomal patients: evaluation of Doppler ultrasonography reproducibility

OBJECTIVE: To evaluate the reproducibility of Doppler ultrasonography in the measurement of portal blood flow volume in schistosomal patients. MATERIALS AND METHODOS: Prospective, transversal, observational and self-paired study evaluating 21 patients with hepatosplenic schistosomiasis submitted to Doppler ultrasonography performed by three independent observers for measurement of portal blood flow. Pairwise interobserver agreement was calculated by means of the intraclass correlation coefficient, paired t-test and Pearson's correlation coefficient. RESULTS: Interobserver agreement was excellent. Intraclass correlation ranged from 80.6% to 93.0% (IC at 95% [65.3% ; 95.8%]), with the Pearson's correlation coefficient ranging between 81.6% and 92.7% with no statistically significant interobserver difference regarding the mean portal blood flow volume measured by Doppler ultrasonography (p = 0.954 / 0.758 / 0.749). CONCLUSION: Doppler ultrasonography has demonstrated to be a reliable method for measuring the portal blood flow volume in patients with portal hypertension secondary to schistosomiasis, with a good interobserver agreement.OBJETIVO: Avaliar a reprodutibilidade do ultra-som Doppler na quantificação do volume de fluxo portal em pacientes esquistossomóticos. MATERIAIS E MÉTODOS: Estudo prospectivo, transversal, observacional e autopareado, avaliando 21 pacientes portadores de esquistossomose hepatoesplênica, submetidos a mensuração do fluxo portal pelo ultra-som Doppler por três observadores, de forma independente, sendo calculada a concordância entre estes, dois a dois, pelo coeficiente de correlação intraclasse, teste t-pareado e grau de linearidade de Pearson. RESULTADOS: A concordância interobservador foi excelente. O coeficiente de correlação intraclasse variou entre 80,6% e 93,0% (IC a 95% [65,3% ; 95,8%]), com coeficiente de correlação de Pearson variando entre 81,6% e 92,7% e sem diferença estatisticamente significante entre os observadores quanto à média do fluxo portal mensurado pelo ultra-som Doppler (p = 0,954 / 0,758 / 0,749). CONCLUSÃO: O ultra-som Doppler é um método confiável para quantificar o fluxo portal em pacientes portadores de hipertensão porta de origem esquistossomótica, apresentando boa concordância interobservador.Universidade Federal de São Paulo (UNIFESP) Escola Paulista de Medicina Departamento de Diagnóstico por ImagemUniversidade Federal de São Paulo (UNIFESP) Escola Paulista de MedicinaUNIFESP, EPM, Depto. de Diagnóstico por ImagemUNIFESP, EPMSciEL

Cuidados perioperatórios em cirurgia digestiva: protocolos eras e acerto – posicionamento do Colégio Brasileiro de Cirurgia Digestiva

Background: The concept introduced by enhanced recovery after surgery protocols modifies perioperative traditional care in digestive surgery. The integration of these modern recommendations components during the perioperative period are highly important to ensure less postoperative complications, reduced length of hospital stay and decreased surgical costs. Aims: The aim of this position paper is to emphasize the most important points of a multimodal perioperative care protocol. Methods:  A careful analysis of each recommendation of both ERAS and ACERTO protocols is presented, justifying its inclusion in the recommended multimodal care of digestive surgery patients. Results: Enhanced recovery programs (ERPs) such as ERAS and ACERTO protocols are a cornerstone in modern perioperative care. Nutritional therapy is highly important in digestive surgery and thus both preoperative and postoperative nutrition care are key to ensure less postoperative complications and to reduce the length of hospital stay. The concept of prehabilitation is another key element in ERPs. Management of crystalloid fluids in a perfect balance in vital. Fluid overload may delay the recovery of patients and increase postoperative complications. Abbreviation of preoperative fast for 2h before anesthesia is now accepted by various guidelines of both surgical and anesthesiology societies. Combined with early postoperative refeeding, these prescriptions are not only safe but can also enhance recovery of patients undergoing digestive procedures. Conclusions: This Brazilian College of Digestive Surgery position paper strongly emphasizes that the implementation of ERPs in digestive surgery represents a paradigm shift in perioperative care, transcending traditional practices and embracing an intelligent approach to patient well-being.   Background: The concept introduced by enhanced recovery after surgery protocols modifies perioperative traditional care in digestive surgery.

Agreement between magnetic resonance imaging and ultrasonography in the classification of schistosomal periportal fibrosis, according to Niamey's criteria

OBJECTIVE: To evaluate the reproducibility of magnetic resonance imaging and the agreement between ultrasound and magnetic resonance imaging in the classification of periportal fibrosis in patients with schistosomiasis based on Niamey's qualitative criteria. MATERIALS AND METHODS: A prospective, double-blinded study was conducted between February 2005 and June 2006 with 20 patients (10 men and 10 women, with ages ranging between 24 and 60 years, mean age 42.7 years) diagnosed with schistosomiasis mansoni. Both ultrasound and magnetic resonance images were independently evaluated by two experienced observers. Interobserver agreement was evaluated for findings of periportal fibrosis on magnetic resonance images and in a comparison between magnetic resonance and ultrasound images. RESULTS: The analysis of magnetic resonance images showed total interobserver agreement in 14 patients (70%). The comparison between ultrasound and magnetic resonance imaging showed agreement between images in only six cases (30%) by observer 1, and in eight cases (40%) by observer 2. CONCLUSION: Magnetic resonance imaging presents a good reproducibility in the evaluation of periportal fibrosis in later stages of schistosomiasis, however, the correlation between magnetic resonance imaging and ultrasound is poor.OBJETIVO: Avaliar a reprodutibilidade da ressonância magnética e a concordância entre a ultra-sonografia e a ressonância magnética na classificação da fibrose periportal em pacientes esquistossomóticos, segundo os critérios qualitativos de Niamey. MATERIAIS E MÉTODOS: Foi realizado estudo prospectivo e duplo-cego, entre fevereiro de 2005 e junho de 2006, em 20 pacientes (10 homens e 10 mulheres, idades entre 24 e 60 anos, média de 42,75 anos) com diagnóstico de esquistossomose mansônica. As imagens de ultra-sonografia e de ressonância magnética foram avaliadas por dois examinadores experientes de forma independente. Foi medida a concordância interobservador para a ressonância magnética e entre a ressonância magnética e a ultra-sonografia. RESULTADOS: A ressonância magnética apresentou resultados concordantes entre os observadores em 14 pacientes (70%). Quando comparamos a ressonância magnética com a ultra-sonografia, obtivemos concordância em apenas seis pacientes pelo observador 1 (30%) e em oito pacientes pelo observador 2 (40%). CONCLUSÃO: A ressonância magnética tem boa reprodutibilidade na avaliação de fibrose periportal em pacientes com esquistossomose avançada, porém sua concordância com a ultra-sonografia é fraca.Universidade Federal de São Paulo (UNIFESP) Escola Paulista de Medicina Departamento de Diagnóstico por ImagemUniversidade Federal de São Paulo (UNIFESP) Escola Paulista de MedicinaUniversidade Federal de São Paulo (UNIFESP) Escola Paulista de Medicina Departamento de GastroenterologiaUniversidade Federal de São Paulo (UNIFESP) Escola Paulista de Medicina Departamento de MedicinaUNIFESP, EPM, Depto. de Diagnóstico por ImagemUNIFESP, EPM, Depto. de GastroenterologiaUNIFESP, EPM, Depto. de MedicinaSciEL

Late evaluation of patients with schistosomiasis, not previously submitted to surgical treatment, after eradication of bleeding esophageal varices by endoscopic sclerotherapy

O autor avaliou, num periodo tardio, trinta e sete doentes com a forma hepatosplenica compensada da esquistossomose e antecedente de hemorragia varicosa, que nao haviam sido submetidos previamente ao tratamento cirurgico da hipertensao portal, e cujas varizes de esofago foram erradicadas por escleroterapia endoscopica, no setor de Endoscopia Digestiva da Disciplina de Gastroenteroiogia Cirurgica da UNIFESP, entre janeiro de 1986 e dezembro de 1994. Constituiram a casuistica 21 pacientes do sexo masculino e 16 do sexo feminino, com idade variando de 17 a 66 anos, sendo a mediana 36 anos. O periodo de acompanhamento apos a erradicacao das varizes variou de 36 a 126 meses, sendo a mediana 59 meses. A tecnica de escleroterapia empregada foi a de injecoes intravaricosas de oleato de monoetanolamina a 3 por cento , realizadas por diferentes examinadores. O numero de sessoes ate que o exame endoscopico evidenciasse a erradicacao das varizes variou de quatro a nove, com a mediana de seis sessoes. O periodo de tempo observado entre o inicio do tratamento endoscopico e a observacao do desaparecimento das varizes variou de tres a 17 meses, sendo a mediana de 7 meses. A hemorragia digestiva foi observada durante o tratamento endoscopico em oito pacientes (21,6 por cento ), sempre controlada com medidas clinicas e endoscopicas. Durante o periodo de acompanhamento apos a erradicacao 62,2 por cento dos pacientes apresentaram varizes esofagicas neoformadas necessitando de novas intervencoes endoscopicas. Na maior parte dos doentes esse diagnostico foi realizado efetivamente e nao determinou complicacoes. A ocorrencia de hemorragia digestiva apos a erradicacao das varizes foi observada em 18,9 por cento dos pacientes, sendo a maior parte causada por cordoesvaricosos neoformados, tambem controlados com medidas clinicas e endoscopicas. Os episodios hemorragicos foram observados apenas ate 0 59º mes apos a erradicacao, sendo todos de leve intensidade, sugerindo que apos esse periodo os pacientes que sao acompanhados com regularidade teriam menor risco de apresentarem novo sangramento. Nao houve nbenhum obito no periodo de acompanhamento e nenhum dos pacientes foi submetidos ao tratamento cirurgico da hipertensao portal. A avaliacao tardia deste grupo de doentes selecionados permitiu as seguintes conclusoes, validas para este grupo selecionado: 1) a maioria dos pacientes apresentou varizes esofagicas neoformadas num perio...(au)BV UNIFESP: Teses e dissertaçõe

Short esophagus: literature incidence

There are controversies regarding existence and incidence of short esophagus. the authors reviewed the literature incidence of short esophagus among operated patients due to gastroesophageal reflux disease in the last 3 years. the overall incidence of short esophagus was 1.53%. the proposed risk factors (paraesophageal hernia, Barrett's esophagus, reoperation, esophageal strictures and access route) do have a higher incidence of short esophagus, with the exception of the Barrett's esophagus. Although several biases can be associated with the review, the authors identified the short esophagus incidence in the literature.Universidade Federal de São Paulo, Dept Surg Gastroenterol, São Paulo, BrazilUniversidade Federal de São Paulo, Dept Surg Gastroenterol, São Paulo, BrazilWeb of Scienc
