Food intake in relation to pouch volume, stoma diameter, and pouch emptying after gastroplasty for morbid obesity.

This study investigated possible determinants of food intake change after gastroplastry. Preoperatively and 6 and 12 months postoperatively, 27 morbidly obese patients were prospectively examined with 7-day food registration and radiologic measurement of pouch volume and stoma diameter. Pouch emptying was determined as the mean transit time by a scintigraphic method.

Pouch emptying of solid foods after gastroplasty for morbid obesity.

To obtain information on possible determinants of weight loss after horizontal gastroplasty, pouch emptying was prospectively investigated in 27 morbidly obese patients. A scintigraphic method was used. Examinations were carried out every 6 months until 2 years after surgery.

Joint distension arthrography for disabling hip pain. A controlled clinical trial.

Thirty-eight patients (age 27-73 years) with unilateral hip pain, restricted movement of the hip joint and radiologically no or only slight osteoarthrosis were studied in a double-blind controlled clinical trial. Twenty-one patients received active treatment with hip joint distension arthrography and 17 received placebo treatment. All patients were assessed clinically on entry, the day after and 3 months after treatment.

Ultrasonography versus roentgenography in suspected instances of cholecystolithiasis.

In a consecutive series of 102 patients with no jaundice and with symptoms of cholecystolithiasis, the predictions from both ultrasonography and cholecystography were compared with the final diagnosis. The accuracy of both examinations was high. However, in 38 per cent, single dose oral cholecystography failed to visualize the gallbladder whereas ultrasonography was conclusive in all patients.
