Changes in gallbladder motility and gallstone formation following laparoscopic gastric banding: METHODS (Part 3)

Ultrasound measurement of gallbladder volume This was carried out using a real time ultrasound device (Diasonic DRF1, Diasonics Inc, USA) with either a linear 3.5 MHz or a 5 MHz transducer, for both controls and obese patients, depending on the patient’s build.

Some have shown impaired gallbladder motility in obese persons, whereas others have reported no difference. Certainly, impaired gallbladder emptying has been implicated when obese patients consume a very low calorie diet or […]
