The morbidity of injuries of the extra-hepatic biliary system

Trauma to the gallbladder is associated with concurrent injuries to the extra hepatic biliary system: A South African experience

INTRODUCTION

Gallbladder trauma is a rare injury. This study aimed to describe the significance of these injuries and the appropriate management strategies.

METHODS

A retrospective study was undertaken at a major trauma centre in South Africa and included all patients diagnosed with a gallbladder injury between January 2012 and October 2020.

RESULTS

A total of 51 cases were included (88% male, mean age: 38 years), with 44 (86%) penetrating trauma cases [28 stab wounds (SW), 16 sustained gunshot wounds (GSW)]. Of the 7 (13%) blunt trauma cases, five were involved in a motor vehicle crash, and two were injured via assault. All patients underwent laparotomy. Full-thickness gallbladder laceration or perforation was the most common type of injury (84%) and all patients with a gallbladder perforation or laceration had a cholecystectomy at index operation. Two out of 5 patients with a gallbladder contusion were managed conservatively without a cholecystectomy and the remaining three had evidence of gallbladder necrosis which were managed with cholecystectomy. Associated extrahepatic bile duct injuries occurred in 4% of cases, and 18 cases (35%) required intensive care unit (ICU) admission. The overall mortality was 8%.

CONCLUSION

Gallbladder injury is rare but when encountered implies a significant degree of trauma. Although cholecystectomy is usually definitive, there is an association with other occult extra-hepatic biliary tract injuries. The severity of the associated injuries usually determines patient outcomes.

Complete Transection of the Cystic Duct and Artery after Blunt Trauma: A Case Report

Extrahepatic biliary tract and gallbladder injuries following blunt abdominal trauma are uncommon. Traumatic cystic duct transection is even rarer, which has frequently caused missed diagnosis and delayed treatment. An 18-year-old female patient with no past medical history was transferred to the Trauma Center of Kyungpook National University Hospital after falling from a height of approximately 20 meters. She became hemodynamically stable after initial resuscitation, and initial contrast-enhanced abdominal computed tomography (CT) showed right kidney traumatic infarction and multiple intrahepatic contusions with minimal fluid collection but no extravasation of the contrast. She was admitted to the intensive care unit. On the second day of hospitalization, her abdomen became distended, with follow-up CT showing a large collection of intra-abdominal fluid. Laparoscopic exploration was then performed, which revealed devascularization of the gallbladder with complete transection of the cystic duct and artery. Laparoscopic cholecystectomy was performed, as well as primary closure of the cystic duct orifice on the common bile duct using a 4-0 Prolene suture. After surgery, no clinical evidence of biliary leakage or common bile duct stricture was observed.

Duodeno-pancreatic and extrahepatic biliary tree trauma: WSES-AAST guidelines

Duodeno-pancreatic and extrahepatic biliary tree injuries are rare in both adult and pediatric trauma patients, and due to their anatomical location, associated injuries are very common. Mortality is primarily related to associated injuries, but morbidity remains high even in isolated injuries. Optimal management of duodeno-bilio-pancreatic injuries is dictated primarily by hemodynamic stability, clinical presentation, and grade of injury. Endoscopic and percutaneous interventions have increased the ability to non-operatively manage these injuries. Late diagnosis and treatment are both associated to increased morbidity and mortality. Sequelae of late presentations of pancreatic injury and complications of severe pancreatic trauma are also increasingly addressed endoscopically and with interventional radiology procedures. However, for moderate and severe extrahepatic biliary and severe duodeno-pancreatic injuries, immediate operative intervention is preferred as associated injuries are frequent and commonly present with hemodynamic instability or peritonitis. The aim of this paper is to present the World Society of Emergency Surgery (WSES) and American Association for the Surgery of Trauma (AAST) duodenal, pancreatic, and extrahepatic biliary tree trauma management guidelines.

Ligation of the Left Hepatic Duct and Proper Hepatic Artery Following a Traffic Accident Injury

A 32-year-old man was admitted to our hospital due to a traffic accident. Intraoperative observations revealed hemoperitoneum, splenic transection, pancreatic tail contusion, comminuted injury in the porta hepatis, rupture in the left hepatic duct, an irregular crevasse in the ductus hepaticus communis, the caudate lobe was transversely broken on the left, and under the gap, there was a fracture in retrohepatic inferior vena cava with huge retroperitoneal hematoma. We carried out a ligation of the left hepatic duct and the proper hepatic artery. Postoperation, the man recovered smoothly. At 5 years and 5 months postoperation, MRI showed that the left liver had atrophied partly. So, we consider that the ligation of the left hepatic duct is a safe procedure for patients without cirrhosis under the conditions of ligation of the proper hepatic artery.

Blunt trauma: An uncommon cause of common bile duct injury

Blunt force trauma to the extrahepatic biliary ductal system as a cause of avulsion is an uncommon injury associated with wide variability in prognosis. These cases are often difficult to identify, primarily as they are complicated by trauma patients exhibiting more immediate and obviously life-threatening injuries. This case demonstrates a 46 year-old-male involved in a head on motor vehicle collision, sustaining blunt force abdominal trauma resulting in partial transection of the common bile duct. Injury was discovered incidentally on exploratory laparotomy post endovascular repair of abdominal thoracic aortic rupture. Open cholescystectomy with intraoperative cholangiogram was performed, isolating extravasation from the common bile duct. A 16-French T-tube was placed in the common bile duct and two large #24 Jackson-Pratt tubes were placed in the vicinity. The procedure was well-tolerated and the patient was discharged with T-tube in place. Discharge was on postoperative day 28 with removal of tubes on postoperative day 54 and the patient was able to make a full recovery.

Extrahepatic duct injury in blunt trauma: two case reports and a literature review

Traumatic injuries of the extrahepatic biliary tract are rare. Associated injuries are usually responsible for immediate indication for surgical treatment, the time when an injury to the extrahepatic biliary ducts may be diagnosed. However, missed injuries are often common. The primary aim of this paper is to describe the clinical features, diagnosis, treatment, and outcome of two patients with left hepatic duct injury after blunt abdominal trauma. As a secondary objective, a literature review is presented. The two cases presented in this study are as follows: (1) A young male, involved in a motor vehicle crash, was admitted with blunt hepatic trauma in a general hospital. Endoscopic retrograde cholangiography was conducted 3 weeks later and revealed a large leakage at the left hepatic duct. Exploratory laparotomy was performed 26 days after the initial traumatic event and identified a complete section of the left hepatic duct, treated with anastomosis. (2) A male fell from a height. On exploratory laparotomy, a 30 % partial injury of the left hepatic duct was found in addition to hemoperitoneum, liver injury, gallbladder detachment together with cystic duct rupture, retroperitoneal hematoma to the right, and cecum hematoma. A high level of suspicion is necessary to identify injuries to the hepatic ducts. Early diagnosis that occurs during laparotomy due to associated injuries is important to reduce complications.

Management of bile duct leaks

The cause of bile duct leaks can be either iatrogenic or more rarely, traumatic. The most common cause is related to laparoscopic cholecystectomy. While surgical repair has been the standard for many years, management in these often morbid and complex situations must currently be multidisciplinary incorporating the talents of interventional radiologists and endoscopists. Based on the literature and in particular the recent recommendations of the European Society of Gastrointestinal Endoscopy (ESGE), this review aims to update the management strategy. The incidence of these complications decreases with surgeon experience attesting to the value of training to prevent these injuries. Bile duct injuries must be categorized and their mapping detailed by magnetic resonance cholangiography MRCP or endoscopic cholangiography (ERCP) when endoscopic therapy is considered. Endoscopic management should be preferred in the absence of complete circumferential interruption of the common bile duct. The ESGE recommends insertion of a plastic stent for 4 to 8 weeks without routine sphincterotomy. For complete circumferential injuries, hepaticojejunostomy is usually necessary. In conclusion, adequate training of surgeons is essential for prevention since the incidence of bile duct injury decreases with experience. Faced with a bile duct injury, a multidisciplinary team approach, involving radiologists, endoscopists and surgeons improves patient outcome.

Isolated extrahepatic bile duct rupture: a rare consequence of blunt abdominal trauma. Case report and review of the literature

A 16-year-old girl suffered blunt abdominal trauma. Clinically, a severe motor impairment with paraesthesia of the legs was found. Posterior osteosynthesis in T10-L1 with laminectomy in T10-T12 and posterolateral arthrodesis in T11-T12 was performed because of a dorsal traumatic vertebral fracture. On hospital day 7, because of an acute abdomen, surgical laparoscopic exploration showed sterile bloody fluid without any evident hemorrhagic injury. On hospital day 11, the patient was reoperated on by the laparoscopic approach for increasing abdominal pain and fever: a peritoneal biliary fluid was aspirated. After conversion to open surgery, cholecystectomy was performed. Intraoperative cholangiography was considered as normal. On arrival at our institution 13 days after injury, the patient was operated on for a biliary peritonitis. Intraoperatively, a trans-cystic cholangiography showed a biliary leakage of the common bile duct; a T-tube was placed into the common bile duct; a subhepatic drainage was placed too. On postoperative day 30, a T-tube cholangiography showed a normal biliary tree, without any leakage, and the T-tube was subsequently removed. The patient had a complete recovery.

Blunt Left Extrahepatic Bile Duct Injury: Case Report and Literature Review

BACKGROUND

Extrahepatic biliary tract injuries following blunt abdominal trauma are very rare and pose a diagnostic and therapeutic challenge.

CASE REPORT

We report a case of blunt liver injury with left extrahepatic duct transection following a motor vehicle collision. Technetium 99m dimethyliminodiacetic acid scan confirmed a bile leak and endoscopic retrograde cholangiopancreatography (ERCP) diagnosed the injury of the left extrahepatic duct. Management was initially conservative, consisting of external drainage along with trials of stent placement. Ultimately, partial left hepatectomy was required to definitively treat the injury.

CONCLUSION

In the setting of suspected biliary tract injury, early ERCP is essential to localize a leak and guide management decisions. In the event of a confirmed bile leak, a trial of nonoperative management consisting of endoscopic ductal decompression along with percutaneous drainage may initially be warranted although is not always successful.

Successful endoscopic treatment of biliary stricture following mesenteric tear caused by blunt abdominal trauma

Biliary duct injuries are frequently iatrogenic, being associated with surgery for gallbladder stones. However, blunt abdominal trauma such as a motor vehicle crash is a rare cause of extrahepatic biliary stricture. A few reports have been published on biliary strictures treated with endoscopic therapy. In the present study, we describe a suprapancreatic biliary stricture associated with mesenteric tear following road traffic accident. We performed endoscopic stent placement, which was successful in relieving the biliary stricture.

Evolving role of endoscopic retrograde cholangiopancreatography in management of extrahepatic hepatic ductal injuries due to blunt trauma: diagnostic and treatment algorithms

Extrahepatic hepatic ductal injuries (EHDIs) due to blunt abdominal trauma are rare. Given the rarity of these injuries and the insidious onset of symptoms, EHDI are commonly missed during the initial trauma evaluation, making their diagnosis difficult and frequently delayed. Diagnostic modalities useful in the setting of EHDI include computed tomography (CT), abdominal ultrasonography (AUS), nuclear imaging (HIDA scan), and cholangiography. Traditional options in management of EHDI include primary ductal repair with or without a T-tube, biliary-enteric anastomosis, ductal ligation, stenting, and drainage. Simple drainage and biliary decompression is often the most appropriate treatment in unstable patients. More recently, endoscopic retrograde cholangiopancreatography (ERCP) allowed for diagnosis and potential treatment of these injuries via stenting and/or papillotomy. Our review of 53 cases of EHDI reported in the English-language literature has focused on the evolving role of ERCP in diagnosis and treatment of these injuries. Diagnostic and treatment algorithms incorporating ERCP have been designed to help systematize and simplify the management of EHDI. An illustrative case is reported of blunt traumatic injury involving both the extrahepatic portion of the left hepatic duct and its confluence with the right hepatic duct. This injury was successfully diagnosed and treated using ERCP.

Duodenal Injuries: A Review

Duodenal injuries are uncommon injuries but are associated with significant morbidity and mortality from a delayed diagnosis in the case of blunt trauma and associated major vascular injuries in penetrating trauma. A simplistic approach with primary repair or resection and anastomosis is ideal for the vast majority. Complex procedures such as pyloric exclusion with or without gastrojejunostomy may be indicated for delayed treatment or severe, high-grade combined pancreato-duodenal injuries. A high index of suspicion and a judicious treatment plan based on a careful consideration of all the available options are crucial for optimal outcome.

Minimally invasive management of bile leaks after blunt liver trauma in children

BACKGROUND

Management of bile leaks after blunt abdominal trauma remains controversial. Conventionally, open surgery has been considered necessary, but new modalities of treatment, including endoscopic biliary stenting and laparoscopy, offer a minimally invasive alternative.

MATERIALS AND METHODS

A retrospective review of all cases of blunt liver trauma in children treated at our institution between May 2002 and October 2004 was performed looking for possible biliary injury.

RESULTS

Five children (3 boys), median age 13 years (range, 10-15 years), were referred to our institution at a median time of 4 days (1-15 days) after the initial trauma. Mechanism of injury was motor vehicle accident (n = 3), fall from a motorbike/Quad bike (n = 2), and a scooter handlebar injury (n = 1). Two, who were hemodynamically unstable, required laparotomy within 24 hours, although their subsequent management was minimally invasive. Endoscopic retrograde cholangiopancreatography, performed at a median time of 15 days (2-28 days), demonstrated an intrahepatic biliary leak in all 5 patients. Biliary stenting was performed in each case, with 2 also having a sphincterotomy. One subsequently developed a bile duct stricture that was managed by endoscopic dilatation. Four required additional percutaneous external drainage of intraabdominal collections. Two underwent laparoscopy to facilitate peritoneal lavage and rule out bowel injuries. No child required open surgery to treat the bile leak. Median hospital stay was 43 days (range, 15-58 days).

CONCLUSIONS

A minimally invasive, multidisciplinary approach to traumatic bile leaks, as an alternative to open surgery, is practical and safe. It requires flexibility, particularly if the diagnosis has been delayed, and may still involve a prolonged hospital stay.

Traumatic pediatric bile duct injury: nonoperative intervention as an alternative to surgical intervention

BACKGROUND

Nonoperative management of blunt pediatric liver injuries has become the standard of care in the absence of hemodynamic instability. However, associated bile duct injuries remain as difficult challenges. Few case reports have demonstrated the benefits of conservative approaches, but others have found better outcomes with surgical intervention. In this study, we report on our experience with interventional endoscopic and radiologic management of 5 pediatric patients with bile duct injuries who underwent unsuccessful surgical interventions.

METHODS

We conducted a retrospective review of medical records of all pediatric patients who were admitted with major blunt liver trauma and bile duct injuries over a period of 5 years.

RESULTS

There were 5 patients (4 boys and 1 girl) whose ages range from 3 to 11 years in this study. All patients had major liver laceration and bilomas. Two had intrahepatic and 3 had extra hepatic bile duct injuries (2 right hepatic ducts and 1 junction of cystic duct with common bile duct). All of them underwent previous laparotomies, once in 2 patients, twice in 2 patients, and thrice in 1 patient. All 5 patients were eventually treated successfully with interventional endoscopic and radiologic techniques. Three underwent endoscopic retrograde cholangiopancreatography stenting with percutaneous drainage. Two patients were managed with percutaneous drainage alone. The follow-up is up to 2.5 years with normal liver function test and bile duct ultrasound.

CONCLUSION

With the current advancement in endoscopic retrograde cholangiopancreatography and intervention radiology techniques, we believe that interventional endoscopic and radiologic management of bile duct injuries caused by blunt trauma in children is successful and efficacious even after multiple laparotomies.

Gall bladder injuries as part of the spectrum of civilian abdominal trauma in South Africa

BACKGROUND

Trauma to the gall bladder is rare, but when missed or improperly managed it may be associated with significant morbidity. The aim of the present study was to review the management and outcomes of gall bladder trauma in a trauma centre.

METHODS

Forty-three patients with gall bladder injury due to abdominal trauma were reviewed over a 3-year period. Surgical management, associated injuries, morbidity and mortality rates were determined.

RESULTS

Among 1242 patients undergoing laparotomy for acute trauma, 43 patients (3.46%) with gall bladder injuries were identified. Forty patients sustained penetrating injuries (37 with gunshot wounds and three with stab wounds), and three patients suffered from blunt trauma. All patients with gall bladder injury underwent abdominal exploration because of associated intra-abdominal injuries. Thirty-six patients were treated with cholecystectomy, four patients underwent primary suture repair of the gall bladder perforation, while three patients with gall bladder injury were treated without any surgical intervention at laparotomy. No complications could be attributed to the gall bladder trauma or surgery.

CONCLUSION

Cholecystectomy is the preferred procedure of choice for gall bladder injuries and is associated with no morbidity.

Drainage perendoscopique d'une plaie traumatique des voies biliaires chez l'enfant

Non-operative management of hepatic injury in children with abdominal trauma represents a standard of care. A major duct injury with persistent bile leakage may result from trauma to the liver. This injury is of concern in patients treated non operatively because it generally requires major hepatic surgery. We report on a case of a 13-year-old boy with an hepatic duct injury from trauma in which healing occurred without surgical repair or resection.

[Conservative treatment of traumatic rupture of the biliary ducts: a case report]

The diagnosis of a biliary duct transection after blunt trauma is difficult in children. Surgery is often performed late and therefore complicated. We present a case of mini-invasive approach for biliary duct transection in a 12-year-old child and review the literature. Transhepatic cholangiography is at the moment the most used technique to make the diagnosis but necessitates general anaesthesia. Stent placement is possible by the way. Endoscopic retrograde cholangiogram (ERCP) has been proposed even in children. Stent placement may be easier by this technique. For the diagnosis, Technetium 99m dimethylminodiacetic acid (HIDA) scanning seems interesting in terms of both sensitivity and specificity. Another promising diagnostic technique is MRI with 3D reconstruction.

Nonoperative management of blunt extrahepatic biliary duct transection in the pediatric patient: case report and review of the literature

An 11-year-old boy sustained a grade IV liver injury and complete disruption of the left hepatic duct (LHD) secondary to a sledding accident. Although he became hemodynamically stable after initial resuscitation in the emergency department and the intensive care unit (ICU), serial paracentesis procedures were necessary to manage abdominal compartment syndrome (ACS). The fluid initially was serosanguinous but subsequently became bile stained. A bile leak was confirmed by a technetium 99m dimethyliminodiacetic acid (HIDA) scan and an endoscopic retrograde cholangiogram (ERCP). The LHD transection was treated with percutaneous drainage of the subhepatic space and a transampullary biliary stent. The leak sealed within 8 days, and follow-up ERCP as an outpatient showed no extravasation but could not visualize the LHD. Repeat computed tomography (CT) scan 3(1/2) months after injury showed the liver laceration to be healed with atrophy of the left lobe and no ductal dilatation. The patient has had a complete recovery, resumed all activities, and currently is 20 months after his injury with no sequelae.

Benefits of early diagnosis and preemptive treatment of biliary tract complications after major blunt liver trauma in children

BACKGROUND/PURPOSE

Nonoperative management of blunt liver trauma may delay diagnosis of related biliary complications leading to delayed surgical intervention and related morbidity. The aim of this study was to see whether technetium (tc) 99 trimethylbromo-im-indolacetic acid (TBIDA) nuclear scan would allow noninvasive early diagnosis of bile leak and pre-emptive management.

METHODS

Retrospective analysis of the patient records and radiologic investigations of 7 patients admitted between April 1998 and December 2000 with "major" blunt liver trauma (parenchymal fracture of less than 4 cm on computed tomography [CT] scan or involving porta hepatis) and various types of biliary complications. Patients with or without early TBIDA diagnosis were compared.

RESULTS

There were 7 patients. The first 2 patients were treated conventionally without TBIDA, and late diagnosis was associated with further related problems (sepsis, life-threatening hemorrhage in both cases) and prolonged hospital stay. The subsequent 5 consecutive patients benefited from early diagnosis (TBIDA scan, 2 to 4 days after trauma), and preemptive management was done (tailored to each case). There was no further or related morbidity. All 7 patients currently are alive and well.

CONCLUSIONS

A TBIDA nuclear medicine scan was efficient in providing an early diagnosis of biliary leakage, thus, allowing adequate preemptive management. In turn, this may have helped avoid related added morbidity compared with cases of late diagnosis. Early TBIDA scan should be performed routinely when the initial CT scan confirms liver trauma graded as "major."

Iatrogenic and Noniatrogenic Extrahepatic Biliary Tract Injuries: A Multi-Institutional Review

Traumatic and iatrogenic extrahepatic biliary tract injuries are rare but may lead to exceedingly morbid complications. Traumatic extrahepatic biliary tract injuries represent less than 1 per cent of all traumatic injuries. Iatrogenic injuries result in 0.2 to 1 per cent of laparoscopic or open cholecystectomies. The objective of this study was to review the incidence of biliary tract injuries—iatrogenic as well as traumatic—and their subsequent management. A multi-institutional chart review was done including Louisiana State University Health Sciences Center (LSUHSC)-Shreveport, LSUHSC-Monroe, and Richland Parish medical centers. Charts were reviewed for patients with iatrogenic biliary tract injuries and those with biliary tract injuries related to noniatrogenic trauma. The etiology of the biliary tract injury, symptoms of injury, pertinent laboratory and radiologic studies, injury-to-diagnosis time, type of biliary tract injury, injury management, days hospitalized, intensive care unit stay, and complications were reviewed. There are 1500 trauma patients admitted to LSUMC-Shreveport each year. The incidence of biliary tract injury in trauma patients admitted to LSUMC is 0.1 per cent. Traumatic injuries were classified according to the injury scale by Mattox et al. (Trauma 1996; Vol 515). There were five Type II, four Type IV, and two Type V injuries. Five patients underwent cholecystectomy, three had endoscopic retrograde cholangiopancreatography with stent placement, and two had choledochojejunostomy; one patient died from associated injuries. There were no complications of repair. Approximately 220 cholecystectomies are done at LSUMC-Shreveport each year. Eighty-eight per cent are laparoscopic, and 12 per cent are open. The incidence of iatrogenic biliary tract injuries at LSUMC-Shreveport during the past 8 years was 0.2 per cent. Immediate diagnosis of iatrogenic injuries was made in five of 17 cases and eight of 11 trauma cases. Laparoscopic injuries were classified by the Way injury classification (Stewart L, Way LW. Arch Surg 1995;130:1123). There were one Type I, one Type II, and nine Type HI injuries. Treatment included suturing of the laceration (n = 1), hepaticojejunostomy (n = 8), and primary repair (n = 2). Open injuries were classified using the Bismuth classification. There were one Type I and three Type III injuries. All were treated with hepaticojejunostomy. There were two iatrogenic injuries unrelated to cholecystectomy. One patient suffered a perforation of the gallbladder during laparoscopic nephrectomy. This patient subsequently underwent cholecystectomy and has done well. The second patient suffered ligation of the intraduodenal portion of the common bile duct during hemigastrectomy and oversewing of a duodenal ulcer. This patient underwent hepaticojejunostomy and has done well. Complications of iatrogenic injury repair included leaking of a repaired laceration (n = 1), failed hepaticojejunostomy (n = 1), and an anastomotic stricture after hepaticojejunostomy (n = 1). Laparoscopic injuries by LSUMC hospitals is 0.2 per cent. Extrahepatic biliary tract injuries resulting from open cholecystectomy were diagnosed later than those occurring during laparoscopic cholecystectomy and were most likely to result in stricture formation. Repair of Way Type II and III injuries is associated with a higher complication rate. Hepaticojejunostomy has a complication rate of 15 per cent. Minor common duct lacerations are amenable to conservative therapy with oversewing and/or endoscopic retrograde cholangiopancreatography with stent placement. Repair of extrahepatic biliary tract injuries with hepaticojejunostomy at a level of good blood supply remains our gold standard for treatment of more severe injuries and strictures.

Duodenal injuries

BACKGROUND

The worldwide increase in road traffic accidents and use of firearms has increased the incidence of duodenal trauma.

METHODS

The English language literature on duodenal trauma over the period 1970-1999 was reviewed.

RESULTS AND CONCLUSION

Upper gastrointestinal radiological studies and computed tomography may lead to the diagnosis of blunt duodenal trauma. Exploratory laparotomy remains the ultimate diagnostic test if a high suspicion of duodenal injury continues in the face of absent or equivocal radiographic signs. The majority of duodenal injuries may be managed by simple repair. More complicated injuries require more sophisticated techniques. High-risk duodenal injuries are followed by a high incidence of suture line dehiscence and they should be treated by duodenal diversion. Pancreaticoduodenectomy should be considered only if no alternative is available. 'Damage control' should precede definitive reconstruction.

An unusual bile duct injury in a child after blunt abdominal trauma

Bile duct injuries are rare in children after blunt trauma. This report describes a 3-year-old child who sustained a blunt abdominal trauma resulting in bile duct, liver, and small bowel injuries. The initial management at another hospital included recognition and repair of a small bowel perforation. However, the postoperative course was complicated by a large biliary leak. The child was transferred to our institution where radioisotope scanning and endoscopic retrograde cholangiography confirmed the extent of the ductal injury. At laparotomy there were injuries of both right and left hepatic ducts, and an anomaly of bile duct course was noted. The right hepatic duct was repaired primarily and the left one was repaired with Roux-en-Y hepaticojejunostomy. Postoperatively, normal bile drainage was documented by radioisotope scan and the patient remains symptom free at 1 year follow-up.

A simple stenting method for management of hepatic ductal injury secondary to blunt abdominal trauma: two case reports

We report two cases of liver injury with hepatic ductal disruption after blunt abdominal trauma. The first case involves a 23-year-old male. Because the bifurcation of the hepatic duct was longitudinally torn, two stenting catheters were inserted toward the right and left hepatic ducts without suture closure of the tear. The patient is well 10 years after the injury. The second case involves a 22-year-old male who suffered an infarction of the inferior portion of the medial segment of the left hepatic lobe as well as a laceration of the left hepatic duct, a 50% circumferential tear. A stenting catheter was introduced into the left hepatic duct, but the defect was not sutured. The patient is well 1.5 years after the injury. The catheter stenting method without suture repair or defect plasty is a simple and effective way to manage hepatic ductal injury.

Conservative treatment of a traumatic tear of the left hepatic duct: case report

Injury to the extra-hepatic biliary system in blunt abdominal trauma is rare and difficult to diagnose. In adults, all reported cases were treated surgically. We report a case of a traumatic tear of the left hepatic duct that was treated successfully by endoscopic retrograde cholangiopancreatography and stenting.

Extrahepatic bile ducts injury: a report on 14 cases

Traumatic injuries of the extrahepatic biliary tract are infrequent, occurring in approximately 0.5% of all patients with blunt and penetrating abdominal trauma. The incidence of this injury due to blunt abdominal trauma is rare. This study reviewed patients with injuries of the extrahepatic biliary tract due to abdominal trauma over a 6-year period to determine the incidence, trauma scores, associated injuries, surgical treatment performed, complications and mortality rate. We report our experience with 14 patients with extrahepatic biliary tract trauma. A review of the literature and the discussion about the management are presented.

Complex duodenal injuries

Duodenal trauma, with early diagnosis and prompt treatment, can be managed effectively by simple surgical techniques. Severe duodenal injuries and those associated with major destruction of adjacent structures (the pancreaticobiliary complex or abdominal vessels) require a more thoughtful strategy that incorporates a careful consideration of the physiologic stability of the patient and the extent of local destruction. Figure 8 summarizes these concepts in an algorithm.

Non-surgical trauma to the extrahepatic biliary tract

Non-surgical trauma to the extrahepatic biliary tract is uncommon and encountered only rarely by surgeons outside specialist hepatobiliary centres. Such injury often results in significant morbidity and mortality. This review outlines the incidence, classification, mechanisms of injury, presentation, diagnostic techniques and management options. Depending on the type of biliary injury identified, an optimal method of repair is suggested. Recommendations are made for surgeons who encounter this type of injury and do not have the appropriate expertise for definitive management.

Primary common bile duct anastomosis in the rat using microsurgical techniques

In a rat model, we attempted to describe the natural healing course of the common bile duct (CBD) after primary microsurgical repair. Fifty-three rats were divided into experimental groups with CBD microsurgical anastomoses and control groups with CBD mobilization and ligation. Examination of three experimental groups at 1 week, 1 month, and 3 months showed evolving inflammation and stricture changes with eventual patent, healed ducts in 92% of animals at the end of 3 months following transection and repair. There were no histologic abnormalities in the livers. There were fibrotic ducts and hepatic stasis and cirrhosis changes in the control group with CBD ligation. This study demonstrates that microsurgical techniques can achieve successful primary biliary repair in the rat.

Non-iatrogenic trauma to the extrahepatic biliary tract

Between 1980 and 1991, 15 cases of non-iatrogenic extrahepatic biliary tract trauma have been managed at Westmead and the Royal Canberra Hospitals. There were seven cases of gall-bladder injury and eight bile duct injuries. Four cases resulted from penetrating trauma whereas 11 resulted from blunt trauma. Associated injuries were common. Cholecystectomy was the preferred method of management for gall-bladder injuries whereas the bile duct injuries were managed by a variety of techniques. There were three deaths in the series, mostly related to associated injuries. Bile duct injuries were associated with longer hospitalization than gallbladder injuries.

Isolated complete transection of the common bile duct due to blunt trauma in a child, and review of the literature

A case of isolated complete transection of the common bile duct due to blunt abdominal trauma in a 3-year-old child is presented. The rarity of this injury and its initial presentation as a pancreatic pseudocyst warrant its description. This patient, the fifteenth child to be reported in the literature, was diagnosed as having a biliary injury following ultrasound-guided percutaneous drainage. Choledochal transection was documented at laparotomy and was successfully treated by proximal cholecystostomy and choledochojejunostomy with Roux-en-Y reconstruction. Delayed diagnosis is common, but this injury should always be kept in mind. Early diagnosis is feasible with the use of the HIDA scan. A review of the literature, modes of diagnosis, and techniques for surgical repair are described.

Traumatic injuries to the porta hepatis: case report and review of the literature

Injuries to the porta hepatis present a rare but life-threatening condition. This report documents a patient surviving injuries to all three structures in the porta hepatis. A literature study sets out the guidelines for the optimal treatment of these lesions.

Management of intrahepatic bile-duct injuries: presentation of two cases

Blunt injury causing laceration of the intrahepatic bile-ducts is fortunately rare. Two cases are presented: neither was diagnosed until 48 h after initial presentation. Both were managed by laparotomy, placement of drains in the liver lacerations, and intravenous nutrition until the leaks had stopped spontaneously. The literature is reviewed and two other cases discussed. Such injuries, once diagnosed, should be treated by surgical placement of drains right at the site of leak.
