[A study on motility of sphincter of Oddi in postcholecystectomy syndrome].
Endoscopic manometry of sphincter of Oddi (SO) and serum levels of gastrin, glucagon, and somatostatin were measured in patients with postcholecystectomy syndrome (n = 12), asymptomatic cholecystectomy patients (n = 6), and controlled subjects (n = 14). Pentagastrin-stimulated gastric acid secretion test was also performed in part of patients who had symptoms or no symptoms after the removal of gallbladder. The results showed that the patients of symptomatic group had hypertonic dyskinesia of SO as shown by deep and wide waves superimposed on high basal pressure plateau of SO. The symptomatic group also had a higher serum level of gastrin and a greater BAO than those of other two groups. No difference of serum levels of glucagon and somatostatin was found among these three groups. The hypertonic dyskinesia of SO and hypergastrinemia are possibly important factors in the pathogenesis of postcholecystectomy syndrome.
