Answer

Other adjunctive procedures that may be performed but that have an unclear utility include visceral fat removal, omentectomy, subcutaneous fat panniculectomy, and large-volume subcutaneous fat liposuction. Klein and colleagues indicated that liposuction in itself has no utility in improving cardiac risk factors among patients with obesity. [196]

Some procedures, such as jaw wiring and insertion of a gastric balloon or a gastric wrap, are no longer popular because of their poor results compared with those of newer procedures and because of their high complication rates. Vagotomy has also declined in popularity, as the weight lost is typically regained within a few years. A few reports suggest that when vagotomy is performed with gastric bypass, it increases weight loss by as much as 20%, but this finding has not been consistently replicable.
