Abstract
PurposeMetabolic and bariatric surgery (MBS) is often considered to be associated with macro- and micronutrient deficiency. A possible treatment option can be the implementation of pancreatic enzyme replacement (PERT) and may lead to better outcomes. We designed a prospective trial investigating the possible impact of PERT in patients undergoing MBS at a high-volume center.Materials and MethodsA prospective two-arm randomized controlled trial was conducted on patients who underwent either sleeve gastrectomy or gastric bypass procedures at a high-volume center. Patients underwent bariatric surgery and follow-up examinations at 3, 6, and 12 months after surgery. Patients were stratified either to the treatment group with PERT or to the control group. The primary endpoint of the study was a change in BMI. Lab testing was carried out to measure secondary endpoints, including albumin and vitamin D levels.ResultsOverall, 204 patients were enrolled. Due to missing follow-ups, surgical complications, and side effects due to Kreon medication, 65 were excluded. Analysis of primary endpoints indicates that PERT does not lead to slower weight loss or BMI reduction. Analysis of secondary endpoints showed significantly better vitamin D levels in patients undergoing MBS and PERT. No statistical difference was seen regarding albumin. In both arms, fatty liver disease improved. Quality of life is positively judged as comparable by patients in both groups.ConclusionHerein, we show an association between PERT and higher vitamin D levels in patients undergoing MBS. An optimized enzymatic environment due to PERT may therefore result in higher vitamin D levels and may improve clinical outcomes in patients undergoing MBS.Graphical
