[Laparotomy indications in pelvic fractures].

Infra-umbilical abdominal section concomitant with peritoneal lavage was applied to 74 patients with pelvic fracture and has proved to be helpful in early diagnosis of intra-abdominal organ injuries. However, the percentage of falsely positive results was found to be as high as 17.3 per cent, in the context of pelvic fractures. This has been attributable to the fact that the pelvic floor is likely to be elevated by the haematoma caused by a pelvic fracture, and the syringe may thus get accidentally into the haematoma.
