Postoperative management of patients with total exocrine pancreatic insufficiency

Abstract

The occurrence of maldigestion and malnutrition was studied in 14 patients who had undergone pancreaticoduodenectomy and occlusion of the Wirsung duct with Neoprene®. Before discharge patients were put on a 70 g/day dietary fat intake. Mean faecal fat excretion was 32·9 g/day without enzyme replacement and fell to 14·2 g/day with pancrelipase supplementation. At discharge all patients were underweight (88 per cent of the usual mean body-weight) and nine patients showed alteration in laboratory nutritional parameters. At the time of discharge a low-fat diet (50 g/day) was prescribed. Six months after surgery, mean faecal fat excretion decreased further to 8·3 g/day (P < 0·01) and all patients but one gained weight, reaching 93 per cent of the usual mean body-weight with normalized nutritional parameters. Our data show that the combination of enzyme replacement therapy and low-fat diet allows good correction of steatorrhoea and a significant improvement in nutritional status.
