As many jejunal segments as possible should be included. If mechanical ileus is suspected, an effort should be made to trace the entirety of the gastrointestinal tract. If this is not possible, all abnormally dilated intestinal segments should be traced orad and aborad until obstruction is confirmed or ruled out. For each gastrointestinal segment, the wall layering, thickness, echogenicity of the mucosa, and luminal contents should be evaluated and documented.17–24 For wall thickness measurements, calipers are set at the hyperechoic border of the serosa and the hyperechoic mucosal luminal interface. Measurement of small intestinal wall thickness is variably reported in the literature in both a longitudinal or transverse plane.17–20 The panel’s consensus is that small intestinal wall thickness should ideally be measured in a longitudinal plane to avoid measurement error caused by obliquity and care should be taken that both walls are equal in wall layer definition and wall thickness to
