Aim:
This study was carried out to evaluate a simplified sonographic technique for the sonographic analysis of antral motility.
Method:
For this purpose the percentage of visually complete contractions (estimated reduction of the antral area > 50%)/2 minutes was compared to the mean amplitude (%) and the mean velocity (%/s) of the contractions.
Results:
The percentage of complete contractions was closely correlated to both the mean amplitude (r = 0.97, p < 0.0001) and the velocity (r = 0.92, p < 0.0001) of the antral contractions.
Conclusion:
Since the simplified technique is regardless to a postprocessing unit, which is not available in many sonolayers, it could be recommended as a valid routine screening method for the detection of antral motility disorders.

Assessment of the Abdomen I: Inspection and Auscultation
The abdominal examination is a cornerstone of clinical medicine, serving as a critical tool in diagnosing various gastrointestinal (GI) diseases. It involves a systematic approach that includes inspection and auscultation, each with distinct yet complementary roles in assessing the abdomen. This article will delve into these two primary methods healthcare professionals use to examine the abdomen.
Inspection of the Abdomen
The first step in any abdominal examination is inspection.
