title: A method for measuring the size of the gastric outlet in obesity surgery.
abstract: A simple method was evolved for measuring the gastric outlet size following surgery for obesity. Measurements are made through a fiberoptic endoscope, using a Fogarty catheter. A "phantom" study showed the method to be accurate and superior to endoscopic estimation without a reference balloon. High interexaminer and intraexaminer reproducibility was confirmed by independent measurements in patients.
