1Department of Surgery, University Hospital, Zurich, Switzerland.
Objective:
To evaluate the routine use of abdominal ultrasonography (US) in patients admitted to the surgical emergency unit with acute abdominal pain.
Design:
Prospective study with a three-step evaluation of patients over a 12-month period.
Setting:
University hospital, Switzerland.
Subjects:
496 patients (male/female = 234/262; mean age 45 years) who presented with acute abdominal pain.
Interventions:
Every patient underwent routine investigations and had an abdominal US by the attending surgeon.
Main Outcome Measures:
Clinical diagnosis, post-ultrasonography diagnosis and final diagnosis.
Results:
US improved the correct diagnostic rate from 348 (70%) to 414 (83%). The diagnostic accuracy for acute appendicitis and biliary tract disease improved after US from 455 (92%) to 488 (98%) and from 463 (93%) to 490 (99%), respectively; the corresponding sensitivities and specificities were 91% and 99% and 94% and 99%.
Conclusions:
Ultrasonography should be part of routine surgical investigation and should be mastered and used by surgeons.

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.

Ultrasound I: Abdominal Ultrasonography
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...
