Radiographic study of patients submitted to total gastrectomy using Safatle reconstruction technique.

BACKGROUND: Ever since the first total gastrectomy, there has always been a great concern in increasing the survival of patients, and with the advance of techniques, in improving the quality of life of these patients. The most common reconstruction technique of the gastrointestinal transit is the Roux-en-Y. The reposition of a functional pouch in place of the resected stomach was proposed to minimize the postprandial symptoms, improve the nutritional grade and consequently, the quality of life. The Safatle reconstruction of the gastrointestinal transit technique consists of, in short, in the association of the interposition of the jejunal loop with partial transit through the duodenum, with an inverted Roux-en-Y and with the creation of a pouch which resembles the dynamics of the stomach, achieved by duodenojejunal segment which has an antiperistalsis emptying. AIM: To assess, by radiographic means, the emptying of the duodenojejunal pouch in patients submitted to total gastrectomy using the Safatle reconstruction technique. METHOD: Twelve patients submitted to total gastrectomy using the Safatle technique due to gastric cancer were studied. They were summoned to perform contrasted radiographies of the esophagus-duodenum-jejunum by the videofluoroscopic method during the months of July and August, 2005. RESULTS: All the patients presented satisfactory movement of the duodenojejunal pouch and an adequate emptying in antiperistalsis without food stasis. There has been an average 25-minute drainage time of the duodenojejunal pouch. CONCLUSION: The duodenojejunal pouch, in the patients submitted to total gastrectomy using the Safatle reconstruction, presented adequate emptying and movement.

RACIONAL: Desde a primeira gastrectomia total, houve sempre a preocupação em aumentar a sobrevida e, com o aprimoramento das técnicas, de melhorar a qualidade de vida. A técnica mais aceita para a reconstrução do trânsito intestinal após gastrectomia total é a em Y-de-Roux. A reposição de um reservatório funcional no lugar do estômago ressecado foi proposta para minimizar os sintomas pós-prandiais, melhorar o grau nutricional e, conseqüentemente, a qualidade de vida. A técnica de reconstrução do trânsito intestinal pós-gastrectomia à Safatle consiste, em síntese, numa associação da interposição de alça jejunal com trânsito parcial pelo duodeno, com o Y-de-Roux invertido, e com a criação de um reservatório que se aproxima da dinâmica do estômago, obtido à custa de um segmento duodenojejunal com esvaziamento em antiperistalse. OBJETIVO: Avaliar, por método radiológico, o esvaziamento da bolsa duodenojejunal em doentes submetidos a gastrectomia total com reconstrução à Safatle. MÉTODO: Foram estudados 12 doentes submetidos a gastrectomia total por câncer gástrico com reconstrução à Safatle, convocados para realizar radiografias contrastadas de esôfago-duodeno-jejuno pelo método videofluoroscópico nos meses de julho a agosto de 2005. RESULTADOS: Todos os doentes apresentaram motricidade satisfatória da bolsa duodenojejunal com adequado esvaziamento em antiperistalse sem estase alimentar. O tempo de esvaziamento da bolsa duodenojejunal foi de 25 minutos em média. CONCLUSÃO: A bolsa duodenojejunal, nos doentes submetidos a gastrectomia total com reconstrução à Safatle, apresentou adequado esvaziamento e motricidade.

Quantitative and qualitative analysis of collagen types in the fascia transversalis of inguinal hernia patients.

BACKGROUND: Inguinal hernia is the second most common surgical case in our field. The anatomical factors alone are not enough to explain the inguinal hernia. Studies show changes in the proportion and quantity of collagen fibers in the developing of inguinal hernia. The greater production of collagen type III compared to the type I could justify the thinning of the fascia transversalis and its weakness. AIM: To determine the quantitative and qualitative changes of collagen in the fascia transversalis in inguinal hernia patients and compare them to findings from corpses without inguinal hernia. METHOD: Prospective case-control study based on the biopsy of fascia transversalis of 27 patients and 24 corpses. The technique used was hematoxylin-eosin and picrosirius colorimetry. RESULTS: The medium percent area of collagen (types I + III) and collagen type I, in both groups, show no statistic difference. The quantity of collagen type III was greater in the patients. Patients classified with Nyhus IIIa presented greater quantity of collagen type III. CONCLUSION: There is no significant difference in the quantity of collagen in the fascia transversalis of patients compared to the controls. An increase in the quantity of collagen type III was found in patients with inguinal hernia and a greater quantity in those patients classified with Nyhus IIIa.

RACIONAL: A hérnia inguinal é a segunda afecção cirúrgica mais comum em nosso meio. Os fatores anatômicos, isoladamente, não são suficientes para explicar a ocorrência das hérnias inguinais. Estudos apontam alterações na proporção e quantidade de fibras colágenas no desenvolvimento da hérnia inguinal. A maior produção de colágeno tipo III em relação ao tipo I poderia justificar o adelgaçamento da fascia transversalis e sua fraqueza. OBJETIVO: Determinar as alterações quantitativas e qualitativas de colágeno na fascia transversalis de doentes com hérnia inguinal e compará-las com achados em cadáveres sem hérnia inguinal. MÉTODOS: Estudo prospectivo caso-controle com análise de biopsia de fascia transversalis de 27 doentes e 24 cadáveres. Utilizou-se a técnica de coloração de hematoxilina-eosina e picrosirius. RESULTADOS: A área percentual média de colágeno (tipo I + tipo III) e colágeno tipo I, nos dois grupos, não apresentou diferença estatística. A quantidade de colágeno tipo III foi maior nos doentes. Doentes classificados com Nyhus IIIa apresentaram maior quantidade de colágeno tipo III. CONCLUSÃO: Não há diferença significativa na quantidade de colágeno em fascia transversalis de doentes comparados com controles. Foi encontrado aumento na quantidade de colágeno tipo III nos doentes com hérnia e em maior quantidade nos doentes classificados como Nyhus IIIa.

Monitoreo fetal no estresante: experiencia en el Hospital Ernesto Torres de Iquique / Nonstress fetal monitoring: experience at the Ernesto Torres Hospital of Iquique

Se efectuaron 690 registros basales no estresantes (RBNE) en 558 pacientes durante la semana que precedió al parto. 90% de los registros fueron reactivos, y 10% no reactivos. No hubo mortinatos en el grupo de pacientes cuyo último registro fue "reactivo", encontrandose uno en el grupo ". Entre las pacientes cuyo último registro fue "no reactivo-hubo un porcentaje significativamente mayor de partos por cesárea, meconio en líquido amniótico y sufrimento fetal. El RBNE es un método útil y no invasor en la evaluación del bienestar fetal
