Simultaneous small-intestinal reconstruction and gastric partitioning as treatment for complications after jejunoileal bypass for morbid obesity.

Three female patients aged 34-35 years, who underwent jejunoileal bypass 11, 5, and 3 years ago, respectively, developed renal tubular acidosis. Furthermore, one of the patients needed prednisone for seronegative polyarthritis that developed 2 years after a revision of her jejunoileal bypass. Because of the possible risk of renal damage from renal tubular acidosis and to avoid recurrent obesity, the patients were offered a simultaneous intestinal reconstruction and gastric partitioning. This combined procedure promptly cured the renal tubular acidosis and the arthritis and simultaneously produced a maintained weight loss.
