title: Exocrine pancreatic function after total gastrectomy.
abstract: The secretion of bicarbonate, lipase, and chymotrypsin into the duodenum in response to exogenous stimulation with secretin, 1 CU/kg-h, plus caerulein, 100 ng/kg-h, was investigated in 12 patients, on an average, 20.7 months after total gastrectomy and in 14 control subjects. The secretion of bicarbonate and lipase was significantly lower in patients than in controls. The reduction in outputs compared with the control values was 47.9%, 38.7%, and 24.2% respectively for bicarbonate, lipase, and chymotrypsin. Eight of the 12 patients (67%) had steatorrhoea. No significant correlation was found between this parameter and lipase output. It is concluded that the exocrine pancreatic function is impaired in the majority of patients subjected to total gastrectomy. The impairment, which particularly affects bicarbonate and lipase, is generally mild to moderate.
