Gallstone Formation after Rapid Weight Loss: A Prospective Study in Patients Undergoing Gastric Bypass Surgery for Treatment of Morbid Obesity. Source: American Journal of Gastroenterology. Aug1991, Vol. 86 Issue 8, p1000-1005. 6p. 2 Charts, 3 Graphs. Abstract: Today’s study examined the occurrence of gallstone Formation in 105 morbidly obese patients undergoing rapid weight loss after proximal gastric bypass surgery.
Intraoperative ultrasonography exhibited gallstones in 20 (19%) and gallbladder sludge in four (4%) patients. Eighty-one patients acquired a normal gallbladder ultrasound. After bariatric surgery, these patients were implemented with periodic gallbladder ultra-sound examinations prospectively. At 6 months, gallstones had developed in 36% and gallbladder sludge in 13% of patients. These percentages remained constant at 12 and 18 months relatively. Body weight declined rapidly after surgery from a mean of 132.3 kg to 95.5, 87.0, and 84.0 kg at 6, 12, and 1. 5 years, respectively.
Gallstones developed a lot more often in the white race, and in women. No significant variations in age, body weight, percent ideal body weight, percent weight loss, or the percent of excess body weight lost existed between patients who developed gallstones or sludge and those who did not.
