Abstract
Background: Surgical intervention is considered an acceptable treatment for morbid obesity. Complications following bariatric surgery procedures (BSPs) may necessitate home parenteral nutrition (HPN). No studies have been published on patients receiving HPN following BSP complications. The study aim was to determine if hypocaloric HPN has an effect on body mass index (BMI), albumin, and HPN complications. Methods: A historic cohort of patients was identified from a clinical database. Obese patients (BMI ≥35 kg/m2) who underwent BSP and received HPN for an anastomotic leak/fistula or bowel obstruction were included. Comparisons for start and end of therapy were made for calorie and protein intake, BMI, white blood cell count, and serum albumin level. Readmissions and metabolic and infectious complications were recorded. Obese patients received hypocaloric feeds to promote weight loss and protein for wound healing. Results: Twenty-three patients were included for an average study length of 1.5 months. Patients received an average of 1.2 g of protein and a median of 13.6 kcal per kg actual body weight (ABW) per day. BMI decreased by 7.1% ± 5.2%, from a median of 39.8 to 37.1, and serum albumin increased by 12.5%, from 2.8 ± 0.5 to 3.2 ± 0.6 g/dL. Readmissions occurred in 52.2% of patients with 40.0% of complications related to HPN. Conclusions: Hypocaloric HPN is efficacious in maintaining adequate nutrition while allowing for weight loss in morbidly obese patients following complications of bariatric surgery. Frequency of HPN complications was comparable to those reported in the literature.
