Abstract
|
|
|
Amputation neuroma always occurs at the distal ends of proximal segments of severed nerves and is characterized by a neural enmeshment in an overgrowth of the Schwannian sheath cells. The usual location of amputation neuroma is in amputed
extremities.
However, amputation neuroma can occur following cholecytectomy due to a rich choledochal nerve plexus. amputation neuroma following cholecystectomy may produce biliary-tract pain, a symptom of postcholecystectomy svndrome and occasionally
jaundice
caused by biliary tract obstruction. Surgical excision of the neuroma may relieve the symptoms. Since the cholecystectomy including laparoscopic approach is such a common surgical procedure, it is important that the knowledge of these sequelae be
known.
the possibility of an amputation neuroma should be kept in mind when patients with postcholecystectomy symptoms are seen clinically after an exclusion of the usual causes of these symptoms. We had experienced a 62 year old woman who complained of
right
upper quadrant pain and jaundice with a past history of a cholecystectomy due to multiple gall stones at 11 years before admission, and she was diagnosed as an amputation neuroma in the hepatic duct bifurcation area by operation. So we report it
with
some review of articles. (Korean J Gastroenterol 1995; 27: 144-149)
