[Diverticulosis of the distal end of the choledochus demonstrated by retrograde endoscopic cholangiopancreatography. Apropos of 5 case reports].
We report on 5 observations (3 females, 2 males, mean age 66 years) of diverticula located on the left side of the distal end of the choledochus, demonstrated by ERCP. No specific symptom due to the diverticula could be found. The pathogenesis of the diverticula of the choledochus is unclear: congenital lesion for most authors, or acquired lesion secondary to reflux of pancreatic juice for others. We propose a hypothesis based on data from manometry of the sphincter of Oddi. The diverticula located above the sphincter of Oddi on a passive segment of the biliary tree could be congenital whereas the diverticula of the high pressure zone (just above the papillary orifice) might be acquired.
