A Two-Step Method for Percutaneous Transhepatic Choledochoscopic Lithotomy
Published on: September 13, 2022
Abstract:
Potential of ultrasonic examination for diagnosis of choledocholithiasis was analyzed in 47 patients. Ultrasonic scanners Acuson 128XP and SONOLINE Elegra with 2-9 MHz sensors were used. Choledocholithisis was diagnosed during transabdominal echography in 38 (80.9%) patients. Method of ultrasound-assisted "vibratory" palpation for diagnosis of mobile concrements of the common bile duct is presented. Causes of 2 (4.3%) false-positive and 7 (14.9%) false-negative results of examination are analyzed.

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...
