Posttraumatic bilhemia: conservative management by percutaneous drainage

Bilhemia: A Rare Complication of Transjugular Intraheptic Portosytemic Shunt

A 56-year-old woman with cirrhosis due to chronic hepatitis C underwent emergent transjugular intrahepatic portosystemic shunt (TIPS) due to a ruptured esophageal varix during esophagogastroduodenoscopy. Following TIPS, the patient experienced a rapid rise in serum bilirubin with no evidence of biliary obstruction or hepatic injury. She was determined to have bilhemia, a rare but serious complication of TIPS.

Hepatic and splenic trauma

The spleen and liver are two organs commonly injured in various forms of abdominal trauma. Their relative size, relatively fixed positions, and abundant vascular supply make them prone both to injury and potential sources of catastrophic haemorrhage. With the evolution of computed tomography (CT), there has been a paradigm shift in the management of such injuries from operative to non-operative means. Advances in imaging techniques have also enabled clinicians to observe such patients for development of complications, and when appropriate, utilise the repertoire of interventional radiology techniques available. This review aims to summarise the epidemiology of splenic and hepatic trauma, the mechanisms of trauma and the classifications used in describing these injuries. The role of commonly used imaging modalities, namely ultrasound and CT, both in the acute setting and in observation of these patients for delayed complications is described, and finally a brief description of the current management strategies of such injuries is given.

[Hepatic trauma. Interventional and conservative therapy]

The non-operative management of hemodynamically stable patients with liver trauma has become the standard of care. Non-operative treatment has a success rate of >80%. In the majority of cases of hemodynamic instability or high grade liver injuries, however, a surgical approach is necessary. As for conservative treatment of liver trauma the surveillance of patients in the ICU is of utmost importance. Repeat CT scans are only necessary in patients with high grade injuries or in case of complications. Interventional procedures, such as the endoscopic retrograde cholangiopancreatography in cases of biliary complications or angiography for vascular complications, are increasingly being used in order to avoid surgery. The success rates of non-operative strategies have been improving continuously over the last decades.

Bilhemia: a fatal complication following percutaneous placement of a transhepatic inferior vena cava catheter in a child

A transhepatic central venous catheter was implanted in a 2-year-old child with a history of multiple venous access procedures and superior and inferior vena cava thrombosis. After 2 weeks, inadvertent dislodgement of the catheter was complicated by a biloma. The biloma was percutaneously drained, but a biliary-venous fistula led to a rapidly progressive and fatal bilhemia. We report this case as an infrequent complication of transhepatic catheterization.

Complications of nonoperative management of pediatric blunt hepatic injury: Diagnosis, management, and outcomes

BACKGROUND

Nonoperative management (NOM) of blunt hepatic injury is the standard of care in the hemodynamically stable pediatric patient, but it is not without pitfalls. The purpose of this study is to assess the incidence and types of complications associated with NOM in terms of diagnosis, management, and outcomes.

METHODS

A retrospective study of pediatric patients with blunt hepatic injuries admitted from 1991 through 1997 to a Level I pediatric trauma center was conducted. All stable patients were initially managed nonoperatively according to the Isolated Liver Laceration Critical Pathway. Surveillance was performed by physical examination and tracking of hematocrit and liver function test (LFT) results. Follow-up ultrasound (US) or computed tomography (CT) were performed as clinically indicated.

RESULTS

In all, 185 patients with nonoperatively managed blunt hepatic injuries were identified during a 7-year period. Over 90% (168/185) were successfully managed nonoperatively without adverse sequelae. Ten patients (5.4%) died: seven as a result of head injury; three as a result of multisystem organ failure; none directly attributable to their hepatic injuries. Complications occurred in seven patients (3.8%) with Grades III or IV right lobe liver lacerations and included biloma (5), hepatic artery pseudoaneurysm with hemobilia (1), and necrotic gallbladder (1). All seven patients (100%) had fever, persistent or worsening right upper quadrant pain, feeding intolerance, and persistently elevated LFTs. Complications were diagnosed by CT or US. Nonoperative treatment of complications was successful in four of the seven patients (57.1%) and consisted of percutaneous drain placement only (1), percutaneous drain placement and endoscopic retrograde cholangiopancreatography (ERCP)-guided stent placement (2) and angioembolization (1). Three patients (42.9%) required laparotomy, one for management of a concomitant pancreatic pseudocyst.

CONCLUSION

Complications of NOM of pediatric blunt hepatic injury are rare, but may include biloma, hepatic artery pseudoaneurysm, and necrotic gallbladder. Complications occur only with Grade III or greater injuries and are accompanied by fever, right upper quadrant pain, feeding intolerance, and persistently elevated LFTs. The clinician must maintain a high index of suspicion for the development of complications and have a low threshold for obtaining a CT or US for diagnosis. Interventional radiology techniques, angiography, and ERCP are useful adjuncts to nonoperative management, but some patients may still require laparotomy for management of complications.

Non-operative management of blunt hepatic trauma

BACKGROUND

Non-operative management is currently considered the treatment of choice in over 50 per cent of adult patients with blunt liver injury. This report reviews the criteria for non-operative management and its potential downside.

METHODS

English language publications were reviewed.

RESULTS

Most reports from major trauma centres in the USA support the non-operative treatment of patients with blunt liver injury if well established criteria are met. Using such criteria, non-operative treatment is successful in 50-80 per cent of cases. Adjunctive radiological techniques may be helpful in managing some complications of non-operative treatment.

CONCLUSION

Non-operative management is safe in haemodynamically stable patients with blunt liver injury. Computed tomography (CT) of the abdomen is extremely useful to document the extent of the damage and the presence of associated injuries, but it is not possible, based on CT alone, to predict failure; careful physiological monitoring in selected patients is indicated to avoid catastrophic complications.
