Obese patients lose more weight with bariatric surgery
than with medical weight-loss treatment. The
laparoscopic Roux-en-Y gastric bypass procedure results
in more short-term weight loss than laparoscopic
adjustable gastric banding, but the latter has fewer
postoperative complications and a lower mortality rate;
long-term comparative data are currently lacking. The
decision regarding which procedure to perform should be
based on individual patient and surgeon factors.
