Infusion of a test solution of gelatin into the proximal jejunum of 5 patients with Billroth II anastomoses with no suspected pancreatic disease produced a mean hydrolysis of 46.2%±4.9 SD of the infused gelatin to dialyzable peptides. In 3 patients with Billroth II anastomoses and chronic pancreatitis, the mean hydrolysis was 16%±2.6 SD. In 5 normal subjects and 7 patients with chronic pancreatitis and no prior surgery, the mean intraduodenal gelatin hydrolysis was 72.4%±9.1 SD and 9.0%±3.6 SD, respectively. These preliminary studies indicate that the gelatin infusion test may be of value in assessing pancreatic function in patients with Billroth II anastomoses in whom a secretin test cannot be performed.
