Abstract

BACKGROUND: After pancreatic surgery, exocrine function is determined by the extent of resection and the amount of remaining pancreatic tissue, and all patients should be evaluated for exocrine pancreatic insufficiency (EPI). Pancreatic enzyme replacement is the mainstay of EPI treatment, since it improves fat absorption, reduces symptoms related to malabsorption and improves quality of life (QoL). OBJECTIVE: Knowing that the adjustment of pancreatic enzymes dose is based on the clinical signs reported by the patient, the present study aims to deepen the clinical evaluation and to evaluate the current protocol of treatment, maintaining or improving patients quality of life. METHODS: A cross-sectional study in which adults were evaluated 6 months or more after pancreatic resection. At time 1, anthropometric evaluation and food recall, clinical evaluation of quality of life (SF-36 questionnaire), intestinal habits and laboratory tests were performed. At time 2 a new consultation was conducted to discuss the results and to provide individualized nutritional guidance. For the correlations analysis the Pearson test was used, for associations the Fisher test and for comparison of means the Mann-Whitney test. RESULTS: 39 patients were evaluated, 22 (56.4%) female; 33 (84.6%) >= 60 years; Time after surgery 14.1 ± 6.8 years; Biochemical tests: at all dosages most patients present results within the reference values, but there is a high prevalence of fat-soluble vitamins deficiency; The patients have good nutritional status since a great part presents eutrophy according to the BMI (46.1%) and according to the percentage of body fat (35.9%); In general they do not report adverse gastrointestinal symptoms: 61.5% with feces formed, 53.8% without abdominal pain, 84.6% without steatorrhea; Adequacy in macronutrient consumption: 51.3% adequate consumption of carbohydrates and lipids, and 64.1% excessive consumption of proteins; Positive correlations: enzyme dose correlates with pain (p = 0.004) and BMI (p = 0.009); that is, patients who report more pain and who weigh more are those who receive the highest doses of pancreatic enzymes; Negative correlations: functional capacity and nutritional assessment parameters such as BMI (p = 0.004), and body fat percentage (p = 0.028), as well as clinical parameters such as enzyme dose (p = 0.022) and number of bowel movements per day p=0.024); Associations: the dietary lipid consumption inadequacy is associated with important gastrointestinal symptoms such as soft stool consistency (p=0.005) and flatulence (p=0.012), and emphasizes the importance of nutritional guidance to patients on pancreatic enzyme replacement therapy. CONCLUSION: Most patients presented good results of biochemical tests, quality of life, macronutrient consumption, nutritional status and gastrointestinal symptoms. Significant correlations and associations have been observed that evidence that nutritional status, food intake and enzyme dose interferes with gastrointestinal symptoms and self-perceived quality of life of patients. Therefore, the current protocol is valid, but should be associated with individualized nutritional guidance (AU)
