Endoscopic biliary manometry was performed to evaluate the motor activity of the sphincter of Oddi (SO) in 28 patients, 13 with juxtapapillary duodenal diverticula (8 with biliopancreatic disease) and 15 without diverticula (10 with biliopancreatic disease). So pressure and the rate of irregular wave pattern of phasic contraction in patients with diverticula were significantly higher than those in patients without diverticula. Especially all the patients with both diverticula and biliary stones had motor disorders of the SO. The patients with diverticula were also divided into three groups by endoscopic findings for the location of diverticular; The papilla of Vater was located close to diverticula (within about 4cm) in group A, on the edge of diverticula in group B, in the diverticula in group C. Diverticula could have more direct effect on the motor activity of the SO in group C. Those results suggest juxtapapillary diverticula have close relationship with the motro activity of the SO and biliopancreatic disease, especially in cases which the papilla of Vater located in the diverticula. We conclude that the motor disorders of the SO might be responsible for biliopancreatic disease in patients with juxtapapillary diverticula.
