Pancreatic trauma in children

Background/Purpose

The aim of this study was to determine the etiology, associated injuries, and outcome of children with pancreatic injuries.

Methods

A retrospective review was conducted of children under 16 years with pancreatic trauma admitted to the Children’s Hospital at Westmead (CHW) from January 1983 to September 2002. Deaths were reported to the New South Wales Paediatric Trauma Death Registry (State Registry) from January 1988 to September 2002.

Results

Sixty-five cases were identified: 46 patients were admitted to CHW, and 22 deaths were reported to the State Registry (including 3 deaths at CHW). The median age was 6 years (range, 1 to 14 years). Boys accounted for 60% (n = 40) of cases, decreasing to 50% (n = 11) of those that died. Motor vehicle injuries (MVI) were the most common mechanism, accounting for 40% of survivors and 77% of those who died. Children were restrained incorrectly in 48% of all cases and in 67% of those who died. Significantly more children who died had head, chest, and abdominal visceral injuries, compared with those who survived. Death occurred as a result of head injuries in 68%, with only 3 deaths directly attributed to pancreatico-duodenal injuries.

Conclusions

Pancreatic injuries remain uncommon in children. The most frequent mechanism was MVI, with incorrect use of passenger restraints an important contributing factor. Whereas mortality was mainly caused by other injuries, 3 deaths were directly attributable to pancreato-duodenal trauma.     

Pancreatic trauma in Scottish children

BACKGROUND: Trauma is the leading cause of death in children. Abdominal trauma is common, but there is little information on pancreatic injuries in UK children. The aim of this study was to investigate the clinical course of children suffering pancreatic trauma in Scotland. METHODS: All children admitted to the three major Scottish paediatric surgery centres with evidence of pancreatic injury were identified. A retrospective case note review of these children was performed using a structured proforma. RESULTS: 16 patients (11 males and 5 females), median age 7 years (range 1-11 years) were identified. The commonest mechanism of injury was the typical bicycle handlebar injury (10/16, 62%). Delays in definitive diagnosis were common due to subtle clinical signs. Increased serum amylase levels upon admission were not necessarily diagnostic for pancreatic injury. The diagnosis was confirmed by ultrasound scanning and/or computerised tomography in all patients. Ten patients (62%) developed pseudocysts and, in seven cases, they settled with non-operative management. There were no deaths and no long-term complications. CONCLUSION: Pancreatic injury in children is rare, and a high index of suspicion is required to make the diagnosis. The commonest mechanism of injury is a direct impact to the epigastrium, typically the bicycle handlebar injury. Presentation and diagnosis are frequently delayed. The incidence of pseudocysts is high, but most can be managed conservatively.     

Pancreatic trauma

Introduction

Pancreatic trauma occurs in approximately 4% of all patients sustaining abdominal injuries. The pancreas has an intimate relationship with the major upper abdominal vessels, and there is significant morbidity and mortality associated with severe pancreatic injury. Immediate resuscitation and investigations are essential to delineate the nature of the injury, and to plan further management. If main pancreatic duct injuries are identified, specialised input from a tertiary hepatopancreaticobiliary (HPB) team is advised.

Methods

A comprehensive online literature search was performed using PubMed. Relevant articles from international journals were selected. The search terms used were: ‘pancreatic trauma’, ‘pancreatic duct injury’, ‘radiology AND pancreas injury’, ‘diagnosis of pancreatic trauma’, and ‘management AND surgery’. Articles that were not published in English were excluded. All articles used were selected on relevance to this review and read by both authors.

Results

Pancreatic trauma is rare and associated with injury to other upper abdominal viscera. Patients present with non-specific abdominal findings and serum amylase is of little use in diagnosis. Computed tomography is effective in diagnosing pancreatic injury but not duct disruption, which is most easily seen on endoscopic retrograde cholangiopancreaticography or operative pancreatography. If pancreatic injury is suspected, inspection of the entire pancreas and duodenum is required to ensure full evaluation at laparotomy. The operative management of pancreatic injury depends on the grade of injury found at laparotomy. The most important prognostic factor is main duct disruption and, if found, reconstructive options should be determined by an experienced HPB surgeon.

Conclusions

The diagnosis of pancreatic trauma requires a high index of suspicion and detailed imaging studies. Grading pancreatic injury is important to guide operative management. The most important prognostic factor is pancreatic duct disruption and in these cases, experienced HPB surgeons should be involved. Complications following pancreatic trauma are common and the majority can be managed without further surgery.     

Pancreatic trauma

The early diagnosis of pancreatic injuries depends on a high degree of clinical suspicion. During laparotomy, exploration of the pancreas and duodenum for suspected injury should be thorough and orderly. In managing these injuries, one should select the simplest procedure that will re-establish the integrity of the upper gastrointestinal tract and control the free escape of pancreatic juices into the surrounding tissue. In general, resection of the distal portion of the body and tail of the pancreas for severe injuries in that area and duodenal diverticularization for injuries involving the pancreatic head are the procedures of choice for preservation of functioning pancreatic tissue.     

Pancreatic trauma

Pancreatic injuries are relatively uncommon and usually accompany injuries to major vessels or other gastrointestinal organs. Because it is these associated injuries that are responsible for the early morbidity and mortality, control of hemorrhage and bacterial contamination takes initial priority over the pancreatic injury. The management of specific pancreatic injury depends on the status of the main pancreatic duct, the degree of parenchymal damage, and the anatomic location of the injury. Complete visualization of the gland and accurate determination of the duct status are key intraoperative maneuvers. Failure to recognize significant pancreatic duct and parenchymal injury is the major cause of postoperative morbidity. The vast majority of pancreatic injuries can be managed by simple drainage with or without debridement or suture. However, the occasional major transection or pancreatic duct injury warrants rigorous efforts at determining the status of the major ducts.     

Pancreatic trauma

Early diagnosis of pancreatic trauma has always been challenging because of the lack of correlation between the initial clinical symptomatology, radiologic and laboratory findings, and the severity of the injury. Thanks to the improved performance of spiral CT scanning and magnetic resonance pancreatography, it is now often possible to make an early diagnosis of pancreatic contusion, to localize the site of the injury, and (most importantly) to identify injury to the main pancreatic duct which has major implications for the management of the case. When the trauma victim is unstable, radiologic work-up may be impossible and urgent laparotomy is required. Control of hemorrhage is the primary concern here and a damage control approach with packing may be appropriate; if the pancreatic head has been destroyed, a pancreaticoduodenectomy with delayed reconstruction may be required. If the trauma victim is stable, the treatment strategy will be governed by a variety of parameters--age, clinical condition, associated local anatomic findings (pancreatitis, injury to the duodenum or biliary tract), involvement of the pancreatic duct, and localization of the injury within the gland (to right or left of the mesenteric vessels).     

Pancreatic trauma

Injuries to the pancreas are relatively rare, occurring in around 10% of case involving serious trauma to the abdominal cavity, with 65% of such injuries resulting trauma occurs only exceptionally, involving only 5% of all injuries. The mortality of this entity is influenced by many factors, especially the age of the injured person, the seriousness of the injury, the duration of the shock, the potentially associated trauma, early diagnosis and correct selection of suitable treatment. The authors present here 4 case reports describing injuries to the pancreas and documenting the diagnostic and therapeutic approaches in cases of this very serious trauma.     

Pancreatic injuries in children

AIMS: There are several different philosophies in the diagnostics of blunt abdominal trauma (BAT), yet none of them has been shown to be superior, although enhanced computed tomography (CT) and diagnostic ultrasonography (US) seem to be the most used methods today. Treatment of pancreatic injury (PI) in children is a matter of controversy, whether operative treatment is needed and to what extent. MATERIAL AND METHODS: Seventeen pancreatic injuries were found in a retrospective analysis of 111 paediatric patients, aged 2-14 years, who underwent a laparotomy because of BAT, between 1968 and 1995 in Turku University Central Hospital. The number of non-operated BAT patients was calculated as 287. RESULTS: During the past two decades, the number of BATs and operations diminished by more than two thirds, but the number of PIs remained the same. Twelve acute operations led to four pancreatic resections, two external drainages and two explorations. PI was present but not the main reason for operation in four cases. Five PIs were operated on later due to postraumatic pseudocyst of the pancreas. CONCLUSIONS: PI was rare (15%) in laparotomies done because of BAT, operations which have diminished by 74% during the last twenty years.When PI was found, a variety of operative procedures was needed.     

Pancreatic injuries in children

Pancreatic injuries over an 11-year period were reviewed. Pedestrian motor vehicle accidents accounted for 45% of the injuries. Diagnosis was made clinically and on raised serial serum amylase levels. Eighty per cent of the patients were managed conservatively. Two patients required emergency surgery for pancreatic trauma. There were no deaths. It is concluded that a conservative approach is successful in most paediatric patients with pancreatic trauma.     

Pancreatic trauma: a case report

Pancreatic trauma is a rare event, accounting for approximately 3% of all blunt abdominal traumas. The related mortality is quite high, around 5-30%, mostly due to the associated haemorrhagic lesions and to the delay in establishing the diagnosis, while pancreatic damage is directly responsible for death in only 5-10% of cases. We report here on a case of severe pancreatic trauma, underestimated initially and treated surgically at a later stage. The literature shows that the main difficulty in cases of pancreatic trauma is still related to failure recognizing the injury or to the frequent delay in diagnosing the condition, above all in haemodynamically unstable patients. In these cases, as in the one treated in this report, the clinical evidence and the priority accorded to the treatment of the shock are factors that tend to limit thorough examination. In haemodynamically stable patients, on the other hand, the multislice CT-scan and MR pancreatography-wirsungography are useful for the diagnosis. The treatment can be either conservative or surgical, depending on the extent of the damage, especially to the Wirsung duct. Surgical treatment with preservation of the entire pancreatic parenchyma, as performed in our case, even if technically demanding, makes it possible to maintain the function of the pancreas, thus reducing the risk of metabolic complications.
