Intestinal bypass for control of severe, morbid obesity was initiated in 1956 by jejunocolic anastomosis, which was modified to a jejunoileal technique after intolerable metabolic complications were experienced. This novel and drastic form of treatment for a frustrating medical problem rapidly came into vogue, and many such operations were performed in the decade between 1965 and 1975. Well-described series have been reported from reputable centers. Caution has been expressed by experienced surgeons and editors about the hazards inherent in the procedure. The incidence and management of the various complications have been difficult to assess, although much valuable and helpful information has been provided by these reports.
