Body composition changes following laparoscopic gastric banding for morbid XXXX .

@entity1 @entity1568 @entity353 @entity28 @entity972
Most reports of outcome following @entity28 surgery report weight and co-morbidity changes only. We studied body composition changes in 17 adult @entity1 (15 F, 2 M, age 43+/-2 years, range 28-58 years), with morbid @entity28 (initial BMI 40.4+/-4.9 kg/m(2), range 34.7-48.8) who were managed surgically by laparoscopically inserting an adjustable gastric band. Body composition was studied before and after surgery (mean interval of 909+/-51 days, range 441-1155 days) using anthropometry (abdominal circumference, AC, sum of four skinfold thicknesses, SFSUM), whole-body @entity972 counting (TBK), in vivo neutron activation analysis total body @entity1568 (TBProtein) and whole-body dual-energy ray absorptiometry (total body percent fat TBF%, and total body bone mineral density TBBMD). Weight loss over the study period was 23.4+/-2.5 kg. ( p<0.0003) with an AC reduction of 20.0+/-4.5 cm ( p<0.008). Both SFSUM and TBF% were significantly reduced ( p<0.02 and p<0.0005 respectively). Both TBK and TBProtein after normalization for sex and height, were significantly ( p<0.0054 and p<0.001 respectively) reduced, but the ratio of loss of fat mass to fat-free mass, at 4.4:1 was usual for @entity353 , and there was no significant changes in the ratio of @entity972 to protein. TBBMD, after normalization relative to a young same sex adult, was not significantly changed. In this group of @entity1 , most of the substantial @entity353 over a 2- to 3-year period was due to loss of fat mass, with relatively less reduction in the components of fat-free mass. Adjustable laparoscopic gastric banding induces fat loss without significant other deleterious effects on body composition.
