[Effect of drugs on endoscopic manometry of the sphincter of Oddi].
We used a catheter passing through the papilla duodeni under the view of endoscope, with persistent perfusion system and transducer, to measure the pressure and contraction frequency of sphincter of Oddi (SO) in 10 healthy persons and 20 patients. Meanwhile, we compared the effect of Buscopan, Nitrostat and Vitamin K3 on the pressure and contraction frequency (CF). SO basal pressure (BP) in healthy group was 5.21 +/- 1.61 kPa (mean +/- s), SO peak pressure (PP) 8.21 +/- 1.34 kPa and CF 6.14 waves/min. In the group of peripapillary fistula, SO pressure decreased significantly and CF slowed down greatly. In comparison with the healthy group, SO pressure and CF in the group of gallbladder stone, choledocholithiasis and pancreatic diseases did not show any change of statistic significance. Intravenous injection of Buscopan could decrease SO peak pressure and BP remarkably. Sublingual administration of Nitrostat and intramuscular injection of Vit K3 could reduce SO PP markedly, SO BP didn't change statistically. It was also showed that spheric and semi-spheric papillae had higher pressure than the flat ones (P less than 0.001).
