Background:
Abdominal wall hernias are a common imaging finding in the abdomen. Ultrasonography (US) is noninvasive and allows the examination of the patient in a physiological manner. High-frequency annular US probes have become an increasingly important diagnostic tool for detecting pathological lesions in superficial organs.
Objectives:
To determine the prevalence of paraumbilical hernias among adult patients by abdominal sonography in a tertiary care hospital and to describe the sonographic technique and findings.
Materials And Methods:
During the 2-year period between January 2008 and December 2009, we performed high-resolution US of the anterior abdominal wall on 302 patients who were referred for different reasons other than the examination of the anterior abdominal wall. The images were taken by a radiologist with 12 years of experience in US, and the images were reviewed by three consultant radiologists with expertise in body imaging.
Results:
A total of 302 patients [169 females (56.0%) and 133 males (44.0%)], ranging in age from 17 to 85 years, with a mean age of 53.5 years, were enrolled in the study. The number of positive cases among females was 42 (24.9%) and that among males was 31 (23.3%).
Conclusion:
High-resolution US is an efficient tool for detecting the presence of paraumbilical hernias and accurately verifying not only their content, but also the possible associated complications.

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.

Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...
