In 100 patients with gallstone, blood glucose, insulin were measured and BT-PAMA test, amino acid consumption test were made. Result: 71 patients were found with symptoms of the gut disorders, 12 cases with hyperglycemia (among them, 6 cases had chronic hepatic disease), 14 with exocrine pancreatic insufficiency, 26 with induration of the head of pancrease. The authors consider that hyper glycemia is correlated with chronic hepatic disease and that the gallstone migration impaires the pancreatic structure and function might be one of the factors which induces the symptom of gut disorders in patients with gallstone.
Objective To explore the effects of CO2 pneumoperitoneum on pancreatic function in diabetic rabbits. Methods Forty-eight rabbits were divided into 4 groups: control group (the group of N0, n=4), the group of T0 (n=4), the group of T10 (n=20), and the group of T15 (n=20). The animal used in the groups of T0, T10 and T15 was diabetic rabbit, and the pressures of pneumoperitoneum of the three groups were 0 mm Hg, 10 mm Hg and 15 mm Hg respectively.The model of diabetic rabbits were made through intrvenous administration of Allxon. Arterial blood samples were collected before the onset of CO2 pneumoperitoneum, 0, 2, 6, 12 hours after deflation for measuring blood glucose, amylase, insulin and C-peptid. Then the rabbits were sacrificed and their pancreases were removed for measuring SOD activity and MDA content. Results After abdominal deflation, the blood glucose, amylase, insulin, C-peptid, MDA content were significantly increased （P＜0.05), and SOD activity was significantly decreased（P＜0.05). Twelve hours after abdominal deflation, the levels of blood glucose, amylase, insulin, C-peptid, MDA content returned to those before pneumoperitoneum was established in group T10. But, those in group T15 were higher （P＜0.05) than the levels before insufflation. The SOD activities in both group T10 and group T15 twelve hours after abdominal deflation were significantly different （P＜0.05） from those before pneumoperitoneum was established. There were statistically significant differences （P＜0.05) between group T10 and T15 in amylase, C-peptid, MDA content and SOD activity. Conclusion CO2 pneumoperitoneum has an certain adverse influence on pancreatic function of the diabetic rabbits. The degree of injury is correlated with the pressure of pneumoperitoneum. Pancreatic function may returned to preoperative level soon after abdominal deflation in group T10, but did not return in group T15.
