Omentoenteropexy was developed as an alternative technique to promote neovascularization in an isolated bowel segment. OBJECTIVE: The aim of the present protocol was to study the long-term viability of an isolated jejunal segment following neovascularization by omentoenteropexy. Long-term survival of a neovascularized bowel segment is an indication that the utilization of this segment as an intestinal graft can be successful. METHODS: To test the proposed surgical technique, 13 Wistar rats were subjected to laparotomy, the jejunum was exposed at 20 cm from the angle of Treitz and a pedicle of greater omentum was isolated. An incision of 6 cm was made along the antimesenteric jejunal border, exposing the submucosa. Omentoenteropexy was performed between the incision of the jejunum and the pedicle of the greater omentum. After seven weeks, the mesentery of the jejunal segment subjected to omentoenteropexy was ligated and isolated from the rest of the jejunum by a complete proximal and distal transversal section. Subsequently, an end-to-end anastomosis was performed to restore the continuity of the bowel. RESULTS: At 10 weeks from the first surgical intervention, the isolated jejunal segment subjected to omentoenteropexy was completely neovascularized and viable. CONCLUSION: No evidence of anatomical or functional intestinal obstruction was observed.
O neuroblastoma metastático para o sistema nervoso central é raro. São relatados dois casos de neuroblastoma de supra-renal em duas crianças brancas, do sexo feminino, com 13 meses e 24 meses de idade, respectivamente. A primeira apresentou metástases intracranianas durante o tratamento para neuroblastoma disseminado. A segunda paciente apresentou sintomatologia inicial de hipertensão intracraniana e o tumor abdominal primário foi descoberto quando a criança foi avaliada de acordo com nosso protocolo clínico. Alertamos para a importância do exame neurológico na criança com neuroblastoma, principalmente quando há metástases para os ossos do crânio e deterioração neurológica.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
