Gastric bypass surgery in patients with psychiatric diagnoses – risk of reoperation and length of hospital stay

Background: Gastric bypass surgery (GBP) is considered a safe method with few complications. Nonetheless, few studies have focused on the risk of post-surgery complications in patients with pre-surgery psychiatric diagnoses, compared to those without. This is a nationwide cohort study encompassing 22,539 patients undergoing GBP in Sweden, 2008-2012. They were identified through the National Patient Register and/or the Prescribed Drug Register. GBP patients with a prior diagnosis of schizophrenia (n=40), bipolar disorder (n=335), depression (n=2100), attention deficit hyperactivity disorder (n=314), substance use disorder (n=971), mental retardation (n=54), eating disorder(n=285), personality disorder (n=551) or self-harm (n=1169), since 1997, or a prescription of antidepressants (n=5,345) since 2005, were not at a higher risk of reoperation before discharge, than patients without these diagnoses (odds ratio 1.75, confidence interval 0.73-4.20 adjusted for age, gender and calendar year).
