Abstract: | We studied the motility of the sphincter of Oddi in 12 patients with suspected sphincter of Oddi dysfunction, in four patients with cystic dilatation of the bile ducts (two Caroli's cases and two fusiform choledochal cyst cases), and in 33 patients with retained common duct stones. In these last 33 patients, the motor activity of the sphincter of Oddi was similar to that recorded in nine control subjects without pancreatic or biliary diseases. In the suspected Oddi dysfunction cases, both the basal sphincteric pressure and the frequency of the phasic contractions were significantly elevated (P<0.001). Patients with biliary cystic dilatation showed an increased basal pressure, but the frequency of the contractions was elevated in only those with choledochal cysts and the amplitude in only one of the two patients with Caroli's disease. Motor disorders of the sphincter of Oddi provide a basis for an alternative etiopathogenesis of cystic disease of the biliary system and a possible explanation for pain and dilatation of the bile duct in patients with suspected sphincter of Oddi dysfunction. |
