This study was performed to describe a new model of strangulation obstruction mimicking the situations relevant to abdominal hernias. The strangulation obstruction was induced either by intra-abdominal ligation of an ileal segment 2 cm in length (n = 20) or by a pursestring suture around a fascial defect with a strangulated intestinal loop placed subcutaneously (n = 20). Ten animals served as sham operated controls (n = 10). All animals were euthanized at 12 h postoperatively; strangulated ileum segments were collected for histopathological examination. Microscopic injury scores were similar in both strangulation groups, which were significantly different from the control group (p <.001). The model described here seems to be appropriate for use in further experimental studies concerning strangulation obstruction injury and its consequences, with the added advantage of visualization of the strangulated intestinal loop beneath the skin.
Extensive bleeding from the perivertebral space is a rare encountered problem in abdominal trauma surgery. In this report, we present a technique for the hemostasis of perivertebral hemorrhage apart from the conventional hemostatic measures in a patient with penetrating injury to the lumbar artery and tributaries. In order to construct a controlled compartment in the retroperitoneal perivertebral cavity, bone cement was plastered alongside the dissection plane near the vertebral wall and hemostasis was achieved. Bone cement application, therefore, may pose as an alternative hemostatic method for patients with uncontrollable bleeding in the perivertebral compartment.
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.
