Traumatic neuroma giving rise to biliary obstruction after reconstructive surgery for iatrogenic lesions of the biliary tract--a report of three cases.

A traumatic neuroma of the biliary tract, most commonly has been described as an amputation neuroma in the cystic duct stump after cholecystectomy. Traumatic neuroma has less frequently been associated with biliary obstruction, and this combination is very rare after reconstructive surgery of the biliary tract. Three patients who had undergone a reconstructive procedure following accidental injury of the biliary tract during cholecystectomy are described. After many years they presented with jaundice due to an obstructive traumatic neuroma in the common hepatic duct (one patient) and in a previous biliary-digestive anastomosis (two patients). Eighteen cases of traumatic neuroma of the biliary tract causing obstructive jaundice, were found in the literature and analysed. As far as we know, a traumatic neuroma located in a previous biliary-digestive anastomosis has not been reported before.
