Abstract
Background
Roux-en-Y gastric bypass surgery (RYGB) as treatment of morbid obesity results in substantial
weight loss. Most published long-term studies have included few patients at the last
follow-up point. The aim of the present study was to explore long-term results in
a large cohort of patients 7–17 years after gastric bypass.
Methods
All 539 patients who had undergone primary RYGB from 1993 to 2003 at Uppsala and Örebro
University Hospitals received a questionnaire regarding their postoperative status.
Blood samples were obtained and the medical charts studied.
Results
Of the 539 patients, 384 responded (71.2% response rate, mean age 37.9 yr, body mass
index 44.5 kg/m2 at surgery, 317 women, and 67 men). At a mean follow-up of 11.4 years (range 7–17),
the body mass index had decreased to 32.5 kg/m2, corresponding to an excess body mass index loss of 63.3%. Similar weight loss was
observed, regardless of the length of follow-up. Orally treated diabetes resolved
in 72% and sleep apnea and hyperlipidemia were improved. Revisional bariatric surgery
had been performed in 2.1% and abdominoplasty in 40.2%. The gastrointestinal symptoms
were considered tolerable. The overall result was satisfactory for 79% of the patients
and 92% would recommend Roux-en-Y gastric bypass to a friend. Attendance to the annual checkups was 37%. Vitamin B12 supplements were taken by 72% and multivitamins by 24%.
Conclusion
At 11 years, substantial weight loss was maintained and revisional surgery was rare.
Surprisingly few patients were compliant with the recommendation of lifelong supplements
and yearly evaluations; however, patient satisfaction was high.
