Jejunoileal bypass (JIB) was a surgical weight-loss procedure performed for the relief of morbid obesity from the 1950s through the 1970s in which all but 30 cm (12 in) to 45 cm (18 in) of the small bowel were detached and set to the side.

Jejunoileal bypass (JIB), popular in the 1960s and 1970s, had remarkable success in achieving weight loss by creating a surgical short bowel syndrome. Our patient had an unusual case of liver disease and provided no history of prior bariatric surgery.

To evaluate the results of jejunoileal bypass for morbid obesity, we studied 100 patients with intact bypasses an average of more than five years after surgery. Mean weight loss at five years...

Jejunoileal bypass, first described in the 1960s, was a malabsorptive procedure in which a 35-cm biliopancreatic limb of proximal jejunum was anastomosed to the terminal ileum 10 cm from the ileocecal valve.

Anteroposterior overhead image from fluoroscopy in 67-year-old woman after jejunoileal bypass shows normal postoperative anatomy, including gastric antrum (a), duodenal bulb (db), duodenum (d), jejunum (j), terminal ileum (t), cecum (c), and region of jejunoileal anastomosis ( arrow ).

All patients underwent a one-stage conversion of the jejunoileal bypass to a gastric bypass. Patients were classified according to (1) postbypass weight, (2) the need for nutritional support, (3) the type and severity of complication, and (4) the time interval between jejunoileal bypass and the onset of the complication and correction of the ...

The jejunoileal bypass (JIB) induced a state of malabsorption by bypassing most of the intestines while keeping the stomach intact. Although the weight loss with the JIB was good, too many patients developed complications such as diarrhea, night blindness (from vitamin A deficiency), osteoporosis (from vitamin D deficiency), protein-calorie ...

Since 1962, jejunoileal bypass has been performed on 59 male and 171 female subjects, aged 18 to 55 years; these patients were followed clinically. Postoperative weight loss at two years averaged 37% in men and 35% in women.

In general, shorter shunts produced more weight loss than standard bypass procedures, but were associated with an increased complication rate. Three new complications of jejunoileal bypass are reported: acute colonic dilation with necrosis, beriberi, and lupus erythematosus.

Jul 26, 2023 · In the 1970s, the ileojejunal bypass (IJB) emerged as an experimental surgical procedure for morbid obesity, although it was first described in the 1950s. Several different approaches were developed based on the original of an end-to-end jejunocolic anastomosis with an elongated blind loop.
