Traumatic Disruption of the Proximal Hepatic Duct: Endoscopic Treatment After Failure of Surgical Repair

Inhaltsübersicht

We describe the successful endoscopic treatment of a patient with nearly complete disruption of the proximal common hepatic duct. A 19-year-old man, as a front-seat passenger wearing a seat-belt, was involved in a motor vehicle accident in December 1998. Laparotomy revealed a rupture of segments V to VIII, with an extended injury of the right hepatic vein and a deep laceration of segment IV to the hepatic hilus with a tangential lesion of the proximal common hepatic duct involving 25 % of the circumference. Right hemihepatectomy and suture repair of the bile duct was performed. Re-operation was required at day 4 because of a major anastomotic leakage, and 2 days later the patient was referred to our institution because of recurrent bile leakage (Figure [1]). Endoscopic retrograde cholangiopancreatography (ERCP) showed almost complete disruption of the proximal hepatic duct. The T-tube was removed and a 10-F 10-cm stent was inserted over the lesion of the defect (Figure [2]). ERCP at 8 months after injury demonstrated a high-grade biliary stricture at the proximal common bile duct (Figure [3]). Endobiliary stenting and repeated balloon dilation procedures were carried out with exchange of the stent every 2 months during the following year. After that year had passed, follow-up ERCP showed no functionally relevant narrowing at the anastomosis. The stent was removed. We continued balloon dilation of the bile duct at 2-month intervals for a second year. After 4.5 years, the patient is well without any clinical or laboratory signs of recurrent stricture (Figure [4]).

Figure 1 Cholangiography via T-tube drainage at POD 4 shows an extravasation of contrast medium at the end-to-end anastomosis of the proximal common bile duct.

Figure 2 Endoscopic retrograde cholangiopancreatography (ERCP) after injury: A 10-F 10-cm stent is placed over the lesion of the traumatic defect.

Figure 3 ERCP at 8 months shows a high-grade stricture near the hepatic bifurcation.

Figure 4 Endoscopic retrograde cholangiography (ERC) demonstrates the result of the treatment 4.5 years after the trauma. There is a stricture that is functionally irrelevant (the diameter of the bile duct is 3 mm), with a good outflow of contrast medium into the duodenum. The intrahepatic bile ducts are not dilated.

Small bile duct strictures can be treated by endoscopic options in most patients [1]. Lateral lesions with a diameter less than 5 mm also can be successfully treated by endoscopic stenting [2]. Lesions of greater than 50 % of the circumference and complete transsections are best managed by bilioenteric anastomosis [3]. In the patient described here, an almost complete disruption of the proximal bile duct was successfully managed by endoscopic stent placement without operative reapproximation of the edges. Currently, nonsurgical interventional procedures, such as endoscopic dilation with stents, can be considered as the primary option in the treatment of patients with post-traumatic bile duct strictures [3]. With good long-term outcomes in 74 % to 90 % of cases after endoscopic treatment, the results are similar to those for surgical repair [4]. Although it is not known which endoscopic procedure in patients with postoperative or post-traumatic strictures is optimal, we recommend the insertion of three 10 F to 12 F stents, with a side-to-side technique and which are not exchanged for a total of at least 12 months [5].
