“…The sphincteric segment functions as the primary regulator of bile flow into the duodenum (1,2). Investigators have identified rhythmic cycles of contraction and relaxation of the choledochal sphincter that are independent of duodenal motility (3). Contraction of the circular smooth muscles obliterates the common bile duct lumen, while contraction of the longitudinal smooth muscles shortens the distal duct, retracting the closed lumen into the bile duct in some cases.…”

“…Judd and Mann [6] first used cholangiomanometry for intraoperative evaluation of biliary tract function, and Caroli et al [7] and Mallet-Guy [4] established radiomanometry in combination with intraoperative cholangiography. Their studies were followed by various approaches, and the constant perfusion method [2,3] and the constant pressure method [5] are currently the most commonly used.…”

Cholangiomanometry in Dilated Bile Ducts without a Dysfunction of Sphincter of Oddi

et al. 1989

To elucidate the pathophysiological state of a dilated bile duct without a dysfunction of the sphincter of Oddi, cholangiomanometry has been carried out by the constant perfusion method with a variable perfusion flow involving four increased steps, 1.2, 3.3, 6.6, and 15 ml/min, instead of the single step amount, 1.2 ml/min, of the usual routine procedure. The subjects consisted of 61 patients with benign biliary tract diseases in whom no abnormality was seen in their intraductal pressure curve by the routine constant perfusion method, as well as no residual stones and no passage disturbance in the papillary region. Twenty-nine of these patients showed no dilatation of the bile duct (nondilated group), while the bile duct was dilated in the remaining 32 (dilated group). Differences in these two groups then were compared in terms of their intraductal pressure curve revealed by our four-step perfusion testing. The two groups showed no differences in the baseline pressure, the elevation time (the time that it took to reach the opening pressure of the sphincter after starting perfusion), the perfusion pressure and the residual pressure at any given perfusion rate in pressure curve pattern. However, in the reduction time, the time that it took for the pressure curve to return to the residual pressure after cessation of infusion, while there was no significant difference for both groups at the routine perfusion rate of 1.2 ml/min, at the high perfusion rates of 3.3, 6.6, and 15/min, the dilated group demonstrated a significant delay, which was in proportion to the increased volume of the perfusion. Further, the dilated group also showed a correlation of r = 0.75 between the diameter of the common bile duct and the delay in the reduction time at the high perfusion rates. These findings suggest that a dilated bile duct without a dysfunction of the sphincter of Oddi may develop bile stasis only when the bile secretion is extremely increased, that is 5 times or more of the normal volume, (3,000 ml or more/day). Although it is highly unlikely that such cases will be encountered clinically, it seems safe to say that a dilated bile duct does not necessarily imply a biliary stasis. Therefore, a routine cholangiomanometric study makes it possible to determine whether such a patient requires a sphincteroplasty or an enterobiliary bypass.

“…It united with the bile duct to form a common channel in only 30 cases; in 57 the ducts opened together into the duodenum through a shallow papilla and in 13 the common bile duct and pancreatic duct had completely separate orifices. Caroli, Porcher, Pequignot, and Delattre (1960), using a cineradiographic technique, showed that reflux of dye into the pancreatic duct occurred only during the phase of relaxation of the sphincter of Oddi and that where the ducts had separate openings contrast material entered the duodenum before passing along the pancreatic duct.…”
