Laparoscopic Versus Transabdominal Ultrasound in Morbidly Obese Patients

Completed

Conditions studied: Cholelithiasis, Ultrasonography, Laparoscopic Gastric Bypass

In brief

The objective of this study is to prospectively compare laparoscopic ultrasound to transabdominal ultrasound for the detection of gallbladder pathology in obese patients presenting for laparoscopic gastric bypass. We hypothesize that laparoscopic ultrasound will be more sensitive and specific for cholelithiasis than transabdominal ultrasound in morbidly obese patients.
