Abstract

BACKGROUND: This review studies the efficacy of the methods of assessment of the abdomen in blunt trauma for the detection of gastrointestinal tract injuries (GITI). METHODS: MEDLINE searches of English language publications on the subjects of diagnostic peritoneal lavage, abdominal computed tomography (CT) in blunt trauma and gastrointestinal tract injuries between 1980 and 1998 were used to identify relevant material. Earlier publications were identified from reference lists. The methodology, data and conclusions of all studies were examined in detail. The contemporary roles of clinical assessment, diagnostic peritoneal lavage, CT and other diagnostic modalities in detection of significant GITI were determined based on the best available evidence. CONCLUSIONS: The most accurate and safest methods of assessment of the abdomen in haemodynamically unstable patients with suspected abdominal injuries following blunt trauma are immediate laparotomy or diagnostic peritoneal lavage (DPL). The goal of assessment of the abdomen in stable patients is to accurately define the site and extent of intra-abdominal injury, in order that further management may be tailored to the specific injuries. The most recent evidence suggests that CT of the abdomen fulfils these criteria better than the other modalities of assessment available. The risk of overlooking a significant GITI on CT scan is minimal provided that unexplained free fluid, bowel wall thickening or enhancement, mesenteric fat streaking and bowel dilatation are taken as evidence of GITI. When scan quality is suboptimal or expert interpretation is unavailable, DPL is recommended. Fully cooperative patients with negligible abdominal signs can be safely observed clinically.
