Obstrução intestinal no idoso

RACIONAL: O envelhecimento da população é realidade sentida na vivência diária, levando à necessidade associada de prover cuidados médicos eletivos e de emergência a um número cada vez maior de idosos. OBJETIVO: Avaliar os aspectos clínicos, terapêuticos e evolutivos de pacientes idosos com obstrução intestinal atendidos no Hospital das Clínicas da Faculdade de Medicina de Botucatu - UNESP. MÉTODOS: Análise retrospectiva de pacientes internados no período de janeiro de 2002 a dezembro de 2006. Foram estudados 50 pacientes, 24 homens e 26 mulheres, com idade média de 74,7 ± 7,4 anos, analisando-se a diferenciação entre obstrução funcional e orgânica; a freqüência das causas obstrutivas; a mortalidade; a incidência dos sinais e sintomas; e correlação laboratorial. RESULTADOS: O quadro obstrutivo intestinal teve as seguintes causas: brida (38%), câncer de colon (24%), hérnias (12%), impactacão fecal (12%), carcinomatose (10%) e volvo da sigmóide (4%). A mortalidade foi de 18% associada à complicações infecciosas em todos os pacientes. CONCLUSÕES: a) A distinção entre a obstrução intestinal funcional e orgânica oferece dificuldade no idoso; b) o câncer do colon constitui-se em importante causa de obstrução intestinal com quadro obstrutivo já na primeira manifestação clínica desse tumor; c) bridas e hérnias são igualmente importantes na etiologia da obstrução intestinal; d) os sinais clínicos obstrutivos são poucos evidentes no idoso e a leucometria é mais fidedigna para este diagnóstico.

Demographic of short gut syndrome: Increasing demand is not followed by referral of potential candidates for small bowel transplantation

Background. Despite improvements in small bowel transplantation (SBTx), early referral of patients with irreversible intestinal failure (IF) remains a major obstacle. In this study we evaluated the demand for SBTx among seven surgical pediatric centers located at least 200 km from our center.Methods. From 1997 to 2001, 640 patients have been treated for neonatal diseases, including 248 who underwent a minor or major intestinal resection. Twenty-four patients with major resections presented with short gut syndrome, requiring total parenteral nutrition (TPN). The greatest demand was in postsurgical neonates with necrotizing enterocolitis, gastroschiesis, onphalocoeles, or midgut volvulus, and in three adults with postradiotherapy arteritis (n = 2) and mesenteric vein thromboses (n = 1). The median length of residual bowel after resection was 20 to 30 cm, without an ileocecal valve. Four patients were referred for SBTx evaluation; three died while awaiting a donor; 20 were not referred, among whom 14 died of TPN complications.Results. Approximately 62 children per year require nutritional support for IF, most of whom develop complications related to TPN. Because many patients who are TPN-dependent develop complications, we believe that early referral would reduce mortality.Conclusions. Greater medical awareness about the feasibility of SBTx procedures and earlier referral may improve results and quality of life after transplant.

Síndrome dilatação-vólvulo gástrico em cães

The gastric dilatation- volvulus (GDV) is an acute and potentially lethal disease, characterized by increased size of the stomach associated with mesenteric rotation on its axis, which affects mainly large breed dogs and giants with deep and narrow chest. The diagnosis is made from the history, physical examination, clinical signs and radiographic evaluation. It is an emergency that requires immediate therapy and consists on protocols to treat shock, gastric decompression, surgical repositioning of the stomach, gastropexy and intensive post-operative care. Despite the significant progress in the elucidation of pathophysiological events, risk factors and treatment, there was almost no progress in determining the root causes of this disease. A significant advance was recently described in the literature on this topic is the technique of gastropexy laparoscopy. Instruct the owners of the high risk breeds is extremely important to avoid situations in which the severity of the illness make the surgical treatment impracticable and the animal’s condition irreversible
