Innervation and ductules in remnants were examined by pathologists. Liver function, onset of cholangitis, jaundice clearance, and survival with the native liver were recorded.

Acetylcholinesterase staining was positive in all plexuses. In patients with bile drainage, those with plexuses had improved postoperative liver function, significantly better jaundice clearance 3 or 6 months postoperatively (50.0% vs. 19.1%, or 90.0% vs. 63.8%, respectively), fewer episodes of early cholangitis (10.0% vs. 34.0%), and better survival (80.0% vs. 61.7%) compared to those without. In addition, a larger area of plexuses was associated with a larger area of ductules (<jats:italic>R<\/jats:italic><jats:sup>2\u2009<\/jats:sup>=\u20090.786, <jats:italic>p<\/jats:italic>\u2009=\u20090.000), less frequent (<jats:italic>p<\/jats:italic>\u2009=\u20090.000) and later cholangitis onset (<jats:italic>p<\/jats:italic>\u2009=\u20090.012), and better jaundice clearance (<jats:italic>p<\/jats:italic>\u2009=\u20090.063).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Increased cholinergic innervation in biliary remnants may help reduce the onset of cholangitis and lead to better and earlier jaundice clearance.
