Abstract

OBJECTIVE: Most patients with chronic pancreatitis develop intractable abdominal pain and malnutrition. A low-fat diet is one of the options used to manage intractable abdominal pain and malnutrition. However, few reports have examined the pain-suppression effect. To investigate the effects of oral ingestion of a low-fat elemental diet composed of purified amino acids on pain and nutritional status in patients with chronic pancreatitis, a multicenter prospective study was conducted. METHODS: Patients with chronic pancreatitis with symptoms of abdominal pain were enrolled. In addition to meals, patients ingested a low-fat elemental diet composed of purified amino acids for 12 weeks. Before and after treatment, patients were asked to indicate their pain grade using a 100-mm horizontal visual analog scale, and nutritional indices, including body mass index and blood levels of pancreatic enzymes, were measured. RESULTS: A total of 596 patients were eligible for analysis. Marked pain reduction was observed with a significant decrease of the mean visual analog scale score by 32.9 mm from 52.9 mm after 12 weeks (P < 0.001). There were also significant improvements in nutritional indices. CONCLUSIONS: An oral low-fat elemental diet composed of purified amino acids, which requires no special treatment procedures, may improve patients' quality of life.
