A traumatic neuroma of the biliary tract is rarely associated with biliary obstruction. However, when it arises in the common bile duct (CBD) and is associated with obstructive jaundice, it is difficult to distinguish it from bile duct cancer. We describe a patient who developed obstructive jaundice and itching, due to CBD stricture, 8 years after innocent blunt abdominal trauma. The stricture was resected and hepatico-jejunal anastomosis was performed. Histological examination revealed a traumatic neuroma and a fibrous scar around the common bile duct. Symptoms disappeared following surgical removal of the lesion. Blunt abdominal injury may cause the late onset of a fibrous scar and traumatic neuroma in the common bile duct. To our knowledge, a traumatic neuroma of the biliary tract after blunt abdominal trauma has not been reported previously. We review the clinical picture of this relatively rare problem, along with its diagnosis, pathogenesis and treatment.
The availability of new imaging modalities has altered the diagnostic approach to patients with abdominal and pelvic trauma. Computed tomography and ultrasound have largely replaced diagnostic peritoneal lavage. Ultrasound is used in most trauma centers as the initial imaging technique for the detection of hemoperitoneum and helps to determine the need for emergency laparotomy. Computed tomography allows for an accurate diagnosis of a wide range of traumatic abdominal and pelvic conditions. The speed of single-detector helical and multi-detector row CT (MDCT) permits a rapid CT examination of the seriously ill patient in the emergency room. In particular, the technology of MDCT permits multiple, sequential CT scans to be quickly obtained in the same patient, which is a great advance in the rapid assessment of the multiple-injured patient. The evolving concepts in trauma care promoting non-operative management of liver and splenic injuries creates the need for follow-up cross-sectional imaging studies in these patients. Computed tomography and, less frequently, MR or ultrasound, are used for this purpose.
Abdominal US and CT play an important role in the initial management of blunt trauma in adults. Ultrasound is an excellent method for detection of free intra-abdominal fluid. It is the modality of choice for initial screening and enables selection of hemodynamically unstable trauma victims with severe hemoperitoneum for immediate surgery. However, even in experienced hands, US is not sufficient to rule out organ injuries reliably. Computed tomography, and particularly multislice CT (MSCT), has several major advantages over US and is currently unsurpassed for the detection of blunt visceral injuries in the abdomen. Computed tomography has a high sensitivity for the detection of parenchymal splenic and hepatic injuries. Injuries of the gastrointestinal tract may be detected with good sensitivity provided that adequate examination technique and careful diagnostic interpretation are combined. The value of CT-based injury-grading systems for predicting the outcome of conservative treatment remains unproven; however, demonstration of direct vascular injuries with CT, e.g., the intrasplenic "contrast blush" sign, may indicate a high likelihood that conservative treatment will fail, thus warranting angiographic embolization or surgery. Monitoring of conservatively treated trauma victims by means of repeat CT studies enables early detection of a variety of delayed, clinically silent complications of trauma, e.g., posttraumatic biloma or bowel devascularization. Catheter angiography may be reserved to selected cases with vascular injuries proven on CT.
