ABSTRACTObjective To evaluate inflammatory reaction, fibrosis and neovascularization in dural repairs in Wistar rats using four techniques: simple suture, bovine collagen membrane, silicon mesh and silicon mesh with suture.Methods Thirty Wistar rats were randomized in five groups: the first was the control group, submitted to dural tear only. The others underwent durotomy and simple suture, bovine collagen membrane, silicon mesh and silicon mesh with suture. Animals were euthanized and the spine was submitted to histological evaluation with a score system […]

Oncologic laparoscopic colectomy represents a fully validated surgical approach to the management of colorectal cancer. However, laparoscopic surgery for distal transverse and descending colon lesions remains a challenging procedure. A total laparoscopic approach to the left colectomy is an interesting option for critically ill patients although reports in the literature on this subject are scarce and its approach still not standardized because of its selective nature for indication. There are several advantages associated with conduction of totally laparoscopic approach to […]

ABSTRACTObjective:To change the gasless fetoscopy technique in order to reduce the diameter of entry orifices in the myometrium.Methods:Seven pregnant ewes were submitted to fetoscopy for repairing a large skin defect measuring 4.0 × 3.0 cm, created in the fetal lumbar region at the gestational age of 100 days. The defect was repaired through continuous suture of the skin with approximation of borders. Gasless fetoscopy was used for performing the suture with three orifices to allow entry of the trocar into […]
