©2013 UpToDate ® Print Email Comparison of pressures in the pancreatic and common duct segments of the sphincter of Oddi Sphincter of Oddi manometry. Comparison of the sphincter of Oddi (SO) pressures obtained from both the pancreatic segment (PD) and common duct (CBD) segment of the SO during catheter pull-through of the sphincter in the same patient. The pressures are equivalent. (BM refers to "black marks" noted on the catheter.) Courtesy of Walter J Hogan, MD. Sphincter of Oddi manometry Sphincter of Oddi (SO) pressure profile obtained by catheter pull-through from the common bile duct (CBD) into the duodenum. The three recording tips (proximal to distal) encompass a 4 mm length. The basal SO pressure and superimposed SO phasic waves are demonstrated in all tips. Courtesy of Walter J Hogan, MD.
