ABSTRACT
The smooth muscle neoplasms from the gastrointestinal tract, such as leiomyomas, leiomyosarcoma and leiomyoblastomas, are rare tumors and represent not more than 1 to 3 per cent of all gastric neoplasms (1,2). The authors report a case of gastric leiomyosarcoma (GL) and discuss the difficulties in the diagnosis, surgical treatment and the factors which are important for prognosis

A mortalidade observada na obstrucao aguda do colon esquerdo e alta quando o classico procedimento em tres tempos e realizado. Em recentes relatos na literatura, a utilizacao da irrigacao per-operatoria permite a realizacao de uma resseccao primaria, seguida de anastomose num unico tempo nesses casos. Na tentativa de verificar esta afirmacao, estudou-se experimentalmente, atraves de parametros fisicos e morfologicos, a cicatrizacao de anastomoses realizadas em vigencia de obstrucao aguda do colon esquerdo, valendo-se ou nao da irrigacao per-operatoria. A obstrucao foi associada com um significativo atraso no processo de cicatrizacao da mucosa nos exames macro e microscopicos da mucosa (p<0,05), porem resultados intermediarios foram observados com uso da irrigacao per-operatoria do colon. Conclui-se que a cicatrizacao esta retardada nas anastomoses realizadas na vigencia de obstrucao, porem a irrigacao per-operatoria minimiza esta condicao adversa.

Acute biliary pancreatitis (ABP) has been treated by early endoscopic sphincterotomy (ES) based on the reports that immediate bilio-pancreatic duct decompression is the main treatment for the satisfactory evolution of these patients. Twenty sequential patients with perfect evidence for ABP were submitted to endoscopic therapy within 24 hours following their admission. Nineteen out of twenty (95 per cent) showed complete remission of the clinical signs and laboratorial data, reinforcing the application of the endoscopic procedure as a good alternative for these patients. There neither endoscopic complications nor deaths among our cases.
