Study of gastric emptying in patients with pancreatic diabetes (chronic pancreatitis) using acetaminophen and isotope.
The gastric emptying function tests were carried out in eight patients with pancreatic diabetes, who were classified into two groups according to the coefficient of variation in the R-R interval in ECG (C.V. R-R) on the normal subjects: < or = the mean - 2SD (the autonomic nerve dysfunction group: AND+ group) and > the mean - 2SD (the autonomic nerve normal group: AND- group). Both the gastric emptying of liquid food by the acetaminophen method and that of solid food by the isotope method were significantly reduced in the AND+ group than in the AND- and normal groups. In addition, a significant correlation was found between the C.V. R-R and the serum acetaminophen concentration (a 45 min value) and the % gastric retention of isotope (a 120 min value). The above results demonstrated that even pancreatic diabetes might be complicated by gastroparesis diabeticorum among autonomic nerve dysfunction. There was a close relation of delayed gastric emptying to the C.V. R-R in ECG or an index of the vagus nerve function.
