Given the high percentage of patients with weight regain after surgery, significant effort has been placed on developing treatment options in the last few years. Tremendous work has taken place in the realm of cognitive behavior therapy, appetite suppressants, and endoscopic procedures with the hope of reducing the need for revision surgery which can be associated with significant complications. Weight regain is unfortunately a common phenomenon associated with all weight loss modalities including bariatric surgery. We now have a number of treatment options that can reverse the weight loss trend.

Background: Since the introduction of percutaneous endoscopic gastrostomy in the 1980s, the prevalence of home enteral nutrition (HEN) support has increased significantly. Despite these increases, many patients are unable to tolerate standard polymeric formulas (SPFs), resulting in significant healthcare resource utilization. Peptide-based diets (PBDs) have emerged as a viable option in SPF-intolerant patients; however, data in the HEN population are lacking. Methods: Retrospective review of our prospectively maintained HEN database was conducted to assess tolerance, efficacy, and impact on healthcare utilization in patients on PBDs. Results: From January 1, 2016, to May 1, 2018, 95 patients were placed on PBDs, with 53 patients being started directly and 42 patients being transitioned from SPFs. In patients transitioned to PBDs, symptoms of nausea and vomiting, diarrhea, abdominal pain, and distention improved significantly. Healthcare utilization also declined significantly, including mean number of phone calls
