Background: Bariatric surgery patients who report physical or sexual abuse form a sizeable cohort that stands out due to psychological comorbidity. Their possible vulnerability to suboptimal weight loss remains of interest. Their risk for malnutrition due to inadequate oral intake following surgery is underexplored. Objectives: Study aims were to determine the effect of self-reported physical or sexual abuse in patients undergoing open biliopancreatic diversion with duodenal switch (BPD/DS) on (a) 3-year weight loss trajectories and (b) timing of feeding jejunostomy tube (J tube) removal. Delayed J tube removal served as an indicator for inadequate oral intake. Methods: In this retrospective cohort study, the sample (N = 189) consisted of all patients who underwent primary BPD/DS by the same surgeon during 2009 and 2010 at a Midwestern health system. All patients had a J tube placed during surgery. Longitudinal mixed models were used for testing differences in weight loss trajectories by abuse status. Results: There were no significant differences in weight loss trajectories by abuse status. The abused group had the J tube in place a mean of 61.9 days (SD = 39.5) compared to 44.8 days (SD = 32.8) for the not abused group, a significant difference. Conclusions: Our use of the best available statistical methods lends validity to previous findings that suggest physical or sexual abuse does not affect weight loss after bariatric surgery. Increased likelihood of persistent inadequate oral intake in the abused group suggests the need for early multidisciplinary interventions that include mental health and nutrition experts.
