Endoscopic retrograde cholangiopancreatography in patients with pancreatic trauma. ACTA ACUST UNITED AC. 2010;68:538-544. [PMID: 20016385 DOI: 10.1097/ta.0b013e3181b5db7a]

Intraoperative endoscopic retrograde cholangiopancreatography for traumatic pancreatic ductal injuries: Two case reports

BACKGROUND

In order to successfully manage traumatic pancreatic duct (PD) leaks, early diagnosis and operative management is paramount in reducing morbidity and mortality. In the acute setting, endoscopic retrograde cholangiopancreatography (ERCP) can be a useful, adjunctive modality during exploratory laparotomy. ERCP with sphincterotomy and stent placement improves preferential drainage in the setting of injury, allowing the pancreatic leak to properly heal. However, data in this acute setting is limited.

CASE SUMMARY

In this case series, a 27-year-old male and 16-year-old female presented with PD leaks secondary to a gunshot wound and blunt abdominal trauma, respectively. Both underwent intraoperative ERCP within an average of 5.9 h from time of presentation. A sphincterotomy and plastic pancreatic stent placement was performed with a 100% technical and clinical success. There were no associated immediate or long-term complications. Following discharge, both patients underwent repeat ERCP for stent removal with resolution of ductal injury.

CONCLUSION

These experiences further demonstrated that widespread adaption and optimal timing of ERCP may improve outcomes in trauma centers.

Management of Traumatic Pancreatic Injuries: Evaluation of 7 Years of Experience at a Single Regional Trauma Center

Purpose Traumatic pancreatic injuries are rare, but their diagnosis and management are challenging. The aim of this study was to evaluate and report our experiences with the management of pancreatic injuries. Methods We identified all adult patients (age >15) with pancreatic injuries from our trauma registry over a 7-year period. Data related to patients’ demographics, diagnoses, operative information, complications, and hospital course were abstracted from the registry and medical records. Results A total of 45 patients were evaluated. Most patients had blunt trauma (89%) and 21 patients (47%) had pancreatic injuries of grade 3 or higher. Twenty-eight patients (62%) underwent laparotomy and 17 (38%) received nonoperative management (NOM). The overall in-hospital mortality rate was 24% (n=11), and only one patient died after NOM (due to a severe traumatic brain injury). Twenty-two patients (79%) underwent emergency laparotomy and six (21%) underwent delayed laparotomy. A drainage procedure was performed in 12 patients (43%), and pancreatectomy was performed in 16 patients (57%) (distal pancreatectomy [DP], n=8; DP with spleen preservation, n=5; pancreaticoduodenectomy, n=2; total pancreatectomy, n=1). Fourteen (31%) pancreas-specific complications occurred, and all complications were successfully managed without surgery. Solid organ injuries (n=14) were the most common type of associated abdominal injury (Abbreviated Injury Scale ≥3). Conclusions For traumatic pancreatic injuries, an appropriate treatment method should be considered after evaluation of the accompanying injury and the patient’s hemodynamic status. NOM can be performed without mortality in appropriately selected cases.

Abdominal Pain After Subtotal Gastrectomy: A First Report of Accessory Pancreatic Fistula

Background

The accessory pancreatic duct (APD) is the main drainage duct of the dorsal pancreatic bud in the embryo and varies greatly during development. An APD fistula is a rare and easily neglected complication. In this case report, the first symptom of the patient was postoperative abdominal pain and fever. He was eventually diagnosed with accessory pancreatic fistula combined with duodenal fistula. Such a case has not been reported in the literature.

Case Summary

A 66-year-old man was emergently hospitalized for abdominal pain. His preliminary diagnosis was perforation of the digestive tract. He developed fever and abdominal pain after emergency subtotal gastrectomy, followed by changes in the colour of the abdominal drainage fluid. An APD fistula and duodenal stump fistula were confirmed by drainage fluid amylase analysis, contrast fistulography and percutaneous transhepatic cholangial drainage (PTCD). After PTCD, nutritional management and drug treatment, the patient recovered well.

Outcome

We found and successfully cured a case of accessory pancreatic duct fistula combined with duodenal stump fistula.

Epidemiological state, predictive model for mortality, and optimal management strategy for pancreatic injury: A multicentre nationwide cohort study

BACKGROUND

Data for establishing the optimal management modalities for pancreatic injury are lacking. Herein, we aimed to describe the epidemiology, identify mortality predictors, and determine the optimal management strategy for pancreatic injury.

METHODS

We identified patients with pancreatic injury between 2004 and 2017 recorded in the Japan Trauma Data Bank. The primary outcome was mortality. Multivariable logistic regression analyses were used to identify factors significantly associated with mortality and to develop a predictive model. Patients were also classified according to the Organ Injury Scaling of the American Association for the Surgery of Trauma (AAST grade I/II or III/IV). Outcomes were compared based on significant confounder-adjusted treatment strategy.

RESULTS

Overall, 743 (0.25%) patients had pancreatic injury. Traffic accident was the most common aetiology. The overall mortality rate was 17.5%, while it was 4.7% for isolated pancreatic injury. AAST grade, Revised Trauma Scale score on arrival, age, and coexistence of severe abdominal injury aside from pancreatic injury were independently associated with mortality. A predictive model for mortality comprising these four variables showed excellent performance, with an area under the receiver operating characteristic curve of 0.89 (95% confidence interval [CI], 0.85-0.93). The in-hospital mortality was higher in patients who underwent celiotomy than in those who did not among those with AAST grade I/II (15.1% vs. 5.3%) and III/IV (13.8% vs. 12.3%). After adjusting for confounders, these differences were not significant with the adjusted odds ratios of 1.41 (95% CI, 0.55-3.60) and 0.54 (95% CI, 0.17-1.67) for AAST grade I/II and III/IV, respectively.

CONCLUSIONS

AAST grade, Revised Trauma Scale score on arrival, age, and coexistence of severe abdominal injury aside from pancreatic injury were prognostic factors of mortality after pancreatic injury. Confounder-adjusted analysis did not show that operative management was superior to non-operative management for survival. Non-operative management may be a reasonable strategy for select pancreatic injury patients, especially in institutions where expertise in interventional endoscopy is available.

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.

Lessons learned from isolated blunt major pancreatic injury: Surgical experience in one trauma centre

INTRODUCTION

The aim of this study was to present our surgical experience of isolated blunt major pancreatic injury (IBMPI), and to compare its characteristic outcomes with that of multi-organ injury.

MATERIALS AND METHODS

From 1994-2015, 31 patients with IBMPI and 54 patients with multi-organ injury, who underwent surgery, were retrospectively studied.

RESULTS

Of the 31 patients with IBMPI, 22 were male and 9 were female. The median age was 30 years (interquartile range, 20-38). Twenty-one patients were classified as the American Association for the Surgery of Trauma-Organ Injury Scale Grade III, and 10 patients as Grade IV. Patients with IBMPI had significantly lower shock-at-triage rates, lower injury severity scores, longer injury-to-surgery time, and shorter length of hospital stay than those with multi-organ injury. There were no statistically significant differences in sex, age, trauma mechanism, laboratory data, surgical procedures, and complications between the two groups. Eight patients with IBMPI underwent endoscopic retrograde pancreatography, and 5 patients with complete major pancreatic duct (MPD) disruption underwent pancreatectomy eventually. The remaining 3 patients had partial MPD injury and two of them received a pancreatic duct stent for the treatment of existing postoperative pancreatic fistula. Spleen-sacrificing distal pancreatectomy (SSDP) was performed in 13 patient with IBMPI, followed by spleen-preserving distal pancreatectomy (n = 12), peripancreatic drainage (n = 4), and central pancreatectomy with Roux-en-Y reconstruction (n = 2). The overall complication rates, related to the SSDP, SPDP, peripancreatic drainage, and central pancreatectomy, were 10/13 (77%), 4/12 (33%), 3/4 (75%), and 2/2 (100%), respectively. Three patients died resulting in a 10% mortality rate, and the other 16 patients developed intra-abdominal complications resulting in a 52% morbidity rate. In the subgroup analysis of the 25 patients who underwent distal pancreatectomy, SPDP was associated with a shorter injury-to-surgery time than SSDP.

CONCLUSIONS

Patients with IBMPI have longer injury-to-surgery times, compared to those with multi-organ injury. Of the distal pancreatectomy patients, the time interval from injury to surgery was a significant associated factor in preserving or sacrificing the spleen.

Approach and Management of Traumatic Retroperitoneal Injuries

Traumatic retroperitoneal injuries constitute a challenge for trauma surgeons. They usually occur in the context of a trauma patient with multiple associated injuries, in whom invasive procedures have an important role in the diagnosis of these injuries. The retroperitoneum is the anatomical region with the highest mortality rates, therefore early diagnosis and treatment of these lesions acquire special relevance. The aim of this study is to present current published scientific evidence regarding incidence, mechanism of injury, diagnostic methods and treatment through a review of the international literature from the last 70 years. In conclusion, this systematic review showed an increasing trend towards non-surgical management of retroperitoneal injuries.

Major pancreatic duct continuity is the crucial determinant in the management of blunt pancreatic injury: a pancreatographic classification

BACKGROUND

To evaluate the management and outcomes of blunt pancreatic injuries based on the integrity of the major pancreatic duct (MPD).

METHODS

Between August 1996 and August 2015, 35 patients with blunt pancreatic injuries underwent endoscopic retrograde pancreatography (ERP). Medical charts were retrospectively reviewed for demography, ERP timing, imaging findings, management, and outcome.

RESULTS

Of the 35 patients, 21 were men and 14 were women, with ages ranging from 11 to 70 years. On the basis of the ERP findings, we propose a MPD injury classification as follows: class 1 indicates normal MPD; class 2, partial injury with intact MPD continuity; and class 3, complete injury with disrupted MPD continuity. Both classes 2 and 3 are subdivided into classes a, b, and c, which represent the pancreatic tail, body, and head, respectively. In this report, 14 cases belonged to class 1, 10 belonged to class 2, and 11 belonged to class 3. Of the 14 patients with class 1 injuries, 10 underwent nonsurgical treatment and 4 underwent pancreatic duct stenting. Of the 10 patients with class 2 injuries, 4 underwent nonsurgical treatment and 6 underwent pancreatic duct stenting. Two of the 11 patients with class 3 injuries underwent pancreatic duct stenting; one in the acute stage developed sepsis that led to death even after converting to distal pancreatectomy plus splenectomy. Of the 11 patients with class 3 injuries, spleen-preserving distal pancreatectomy was performed in 6, distal pancreatectomy plus splenectomy in 2, and Roux-en-Y pancreaticojejunostomy after central pancreatectomy in 2. The overall pancreatic-related morbidity rate was 60% and the mortality rate was 2.8%.

CONCLUSION

Based on our experience, class 1 and 2 injuries could be treated by nonsurgical means and pancreatic duct stenting could be an adjunctive therapy in class 2b and 2c injuries. Operation is warranted in class 3 injuries.

Conservative treatment using an endoscopic pancreatic stent in a patient with delayed diagnosis of pancreatic injury after blunt trauma: A case report

The diagnostic evaluation of pancreatic injuries has improved dramatically in recent years. However, it is sometimes difficult to diagnose pancreatic injuries. Surgical treatment after delayed diagnosis is associated with increased risks of mortality and morbidity. A 47-year-old man was referred to our emergency department after experiencing blunt abdominal trauma 5 d earlier. The patient was diagnosed with a grade-III pancreatic injury. His hemodynamic status remained stable. He was managed successfully using endoscopic pancreatic stenting and percutaneous drainage catheter insertion.

Pancreatic trauma: Management and literature review

Pancreatic injury is an uncommon event often difficult to diagnose at an early stage. After abdominal trauma, the surgeon must always be aware of the possibility of pancreatic trauma due to the complications associated with missed pancreatic injuries. Due to its retroperitoneal position, asociated organs and vascular injuries are almost always present, which along with frequent extra abdominal injuries explain the high morbidity and mortality. The aim of this study is to present a concise description of the incidence of these injuries, lesional mechanisms, recommended diagnostic methods, therapeutic indications including nonoperative management, endoscopy and surgery, and an analysis of pancreas-specific complications and mortality rates in these patients based on a 60-year review of the literature, encompassing 6,364 patients. Due to pancreatic retroperitoneal position, asociated organs and vascular injuries are almost always present, which along with frequent extraaabdominal injuries explain the high morbidity and mortality of these patients.

Outcomes of Endoscopic Stenting for Traumatic Biliary and Pancreatic Fistulae

The role of endoscopic retrograde cholangiopancreatography (ERCP) in the trauma patient is limited. Therefore, reporting of outcomes is sparse in the literature. The purpose of this study was to review outcomes of patients who underwent ERCP for traumatic biliopancreatic injury. We retrospectively reviewed 1550 ERCPs, from a prospectively maintained database, performed by a single surgical endoscopist consulted by the trauma surgical service for the management of traumatic fistulae. Referral was made for patients with high output (greater than 200 mL/d) and/or persistent (failure to resolve within 30 days) fistulae and traumatic biliary stricture. Primary end point was postprocedural complications. Secondary end points included patient characteristics, stents placed, and duration of stenting. Seventeen patients underwent a total of 31 ERCPs for biliary and/or pancreatic injury resulting from abdominal trauma (eight penetrating, nine blunt). Fourteen patients had ERCP after laparotomy, with a mean interval to ERCP of 74 days. In three patients, ERCP was the only intervention required. Fourteen biliary stents were placed, seven of which were metallic. Ten pancreatic stents were placed; one proximally migrated but was successfully retrieved. Four patients had both ducts simultaneously stented. The mean duration of stenting was 158 days. All fistulae resolved after stenting. There were no serious complications.

Early endoscopic treatment of blunt traumatic pancreatic injury

Blunt pancreatic trauma is a rare and challenging situation. In many cases, there are other associated injuries that mandate urgent operative treatment. Morbidity and mortality rates are high and complications after acute pancreatic resections are common. The diagnosis of pancreatic injuries can be difficult and often requires multimodal approach including Computed Tomography scans, Magnetic resonance imaging and Endoscopic retrograde cholangiopancreaticography (ERCP). The objective of this paper is to review the application of endoprothesis in the settings of pancreatic injury. A review of the English literature available was conducted and the experience of our centre described. While the classical recommended treatment of Grade III pancreatic injury (transection of the gland and the pancreatic duct in the body/tail) is surgical resection this approach carries high morbidity. ERCP was first reported as a diagnostic tool in the settings of pancreatic injury but has in recent years been used increasingly as a treatment option with promising results. This article reviews the literature on ERCP as treatment option for pancreatic injury and adds further to the limited number of cases reported that have been treated early after the trauma.

Blunt pancreatic trauma: A persistent diagnostic conundrum?

Blunt pancreatic trauma is an uncommon injury but has high morbidity and mortality. In modern era of trauma care, pancreatic trauma remains a persistent challenge to radiologists and surgeons alike. Early detection of pancreatic trauma is essential to prevent subsequent complications. However early pancreatic injury is often subtle on computed tomography (CT) and can be missed unless specifically looked for. Signs of pancreatic injury on CT include laceration, transection, bulky pancreas, heterogeneous enhancement, peripancreatic fluid and signs of pancreatitis. Pan-creatic ductal injury is a vital decision-making parameter as ductal injury is an indication for laparotomy. While lacerations involving more than half of pancreatic parenchyma are suggestive of ductal injury on CT, ductal injuries can be directly assessed on magnetic resonance imaging (MRI) or encoscopic retrograde cholangio-pancreatography. Pancreatic trauma also shows temporal evolution with increase in extent of injury with time. Hence early CT scans may underestimate the extent of injures and sequential imaging with CT or MRI is important in pancreatic trauma. Sequential imaging is also needed for successful non-operative management of pancreatic injury. Accurate early detection on initial CT and adopting a multimodality and sequential imaging strategy can improve outcome in pancreatic trauma.

Management of blunt pancreatic trauma: what's new?

Pancreatic injuries are relatively uncommon but present a major challenge to the surgeon in terms of both diagnosis and management. Pancreatic injuries are associated with significant mortality, primarily due to associated injuries, and pancreas-specific morbidity, especially in cases of delayed diagnosis. Early diagnosis of pancreatic trauma is a key for optimal management, but remains a challenge even with more advanced imaging modalities. For both penetrating and blunt pancreatic injuries, the presence of main pancreatic ductal injury is the major determinant of morbidity and the major factor guiding management decisions. For main pancreatic ductal injury, surgery remains the preferred approach with distal pancreatectomy for most injuries and more conservative surgical management for proximal ductal injuries involving the head of the pancreas. More recently, nonoperative management has been utilized, especially in the pediatric population, with the potential for increased rates of pseudocyst and pancreatic fistulae and the potential for the need for further intervention and increased hospital stay. This review presents recent data focusing on the diagnosis, management, and outcomes of blunt pancreatic injury.

The epidemiology of and outcome from pancreatoduodenal trauma in the UK, 1989-2013

INTRODUCTION

Pancreatoduodenal (PD) injury is an uncommon but serious complication of blunt and penetrating trauma, associated with high mortality. The aim of this study was to assess the incidence, mechanisms of injury, initial operation rates and outcome of patients who sustained PD trauma in the UK from a large trauma registry, over the period 1989-2013.

METHODS

The Trauma Audit and Research Network database was searched for details of any patient with blunt or penetrating trauma to the pancreas, duodenum or both.

RESULTS

Of 356,534 trauma cases, 1,155 (0.32%) sustained PD trauma. The median patient age was 27 years for blunt trauma and 27.5 years for penetrating trauma. The male-to-female ratio was 2.5:1. Blunt trauma was the most common type of injury seen, with a ratio of blunt-to-penetrating PD injury ratio of 3.6:1. Road traffic collision was the most common mechanism of injury, accounting for 673 cases (58.3%). The median injury severity score (ISS) was 25 (IQR: 14-35) for blunt trauma and 14 (IQR: 9-18) for penetrating trauma. The mortality rate for blunt PD trauma was 17.6%; it was 12.2% for penetrating PD trauma. Variables predicting mortality after pancreatic trauma were increasing age, ISS, haemodynamic compromise and not having undergone an operation.

CONCLUSIONS

Isolated pancreatic injuries are uncommon; most coexist with other injuries. In the UK, a high proportion of cases are due to blunt trauma, which differs from US and South African series. Mortality is high in the UK but comparison with other surgical series is difficult because of selection bias in their datasets.

The role of endoscopic retrograde pancreatography in pancreatic trauma: a critical appraisal of 48 patients treated at a tertiary institution

BACKGROUND

Endoscopic retrograde pancreatography (ERP) is useful in the diagnosis and treatment of selected patients with pancreatic trauma. We analyzed the role of ERP in treating persistent complications of pancreatic injuries at a tertiary institution.

METHODS

Patients with pancreatic trauma who underwent ERP were identified from a prospective database of 426 pancreatic injuries from January 1983 to January 2011. Patient demographics, mechanism of injury, time to presentation, method of diagnosis, associated injuries, clinical management, endoscopic interventions and their timing, surgical treatment, and patient outcomes were evaluated.

RESULTS

Forty-eight patients underwent ERP after blunt (n = 26) or penetrating (n = 22) pancreatic injury. Median time from injury to ERP was 38 days (range, 2-365 days). Diagnostic ERP was successful in 47 patients. In 11 patients, ERP demonstrated an intact main duct with minor peripheral injuries, and no further intervention was required. A pancreatic fistula was demonstrated in 24, a main pancreatic duct stricture in 12, and a pseudocyst in 10 patients. Fifteen patients had a pancreatic duct sphincterotomy, seven had a pancreatic stent inserted, and six had an endoscopic pseudocyst drainage. Ten patients ultimately required surgery, seven of whom had demonstrated a severe pancreatic duct stricture. Operations performed following ERP were distal pancreatectomy (n = 6), pancreaticojejunostomy (n = 3) and cyst-jejunostomy (n = 1).

CONCLUSION

ERP allowed one quarter of the patients to be treated conservatively. Half had a successful intervention by ERP. Success was most likely in those with fistulae and pseudocysts. Surgery was ultimately avoided in more than three quarters of the patients.

LEVEL OF EVIDENCE

Complete traumatic main pancreatic duct disruption treated endoscopically: a case report

Introduction

Pancreatic injury is uncommon and the management remains controversial. The integrity of the main pancreatic duct is considered the most important determinant for prognosis.

Case presentation

A 19-year-old Greek man was referred to our tertiary referral centre due to blunt abdominal trauma and an associated grade III pancreatic injury. He was haemodynamically stable and his initial treatment was conservative. Due to deterioration in his clinical symptomatology he underwent an endoscopy 20 days postinjury, where a stent was placed in the proximal pancreatic duct remnant and a bulging fluid collection of the lesser sac was drained transgastrically. He made an uneventful recovery and remains well 7 months postinjury, but a stricture with upstream dilatation of his main pancreatic duct has developed.

Conclusions

The clinical status of the patient rather than the grade of pancreatic injury should be the principal determinant to guide treatment. Endoscopic stenting and drainage is an attractive minimally invasive procedure and it may obviate the need for surgery. However, further investigation is required regarding the safety and outcome.

Endoscopic management for pancreatic injuries due to blunt abdominal trauma decreases failure of nonoperative management and incidence of pancreatic-related complications

INTRODUCTION

The actual benefit of endoscopic techniques in the non-operative management (NOM) of pancreatic injury is still unclear, with its role and effectiveness in the NOM of pancreatic injury remains defined and doubted. The purpose of this study was to evaluate the feasibility and long-term results of endoscopic techniques in the NOM of blunt pancreatic injury, and to determine whether NOM can be performed safely for selective patients with pancreatic injury.

PATIENTS AND METHODS

The records and follow-up data of all patients with blunt pancreatic injuries over 16-year period from October 1, 1996, to September 30, 2012 at our department were retrospectively reviewed. Failure of NOM (FNOM) occurred if laparotomy was required after attempted NOM.

RESULTS

132 patients (32% of all patients with blunt pancreatic injury) underwent NOM, including 58 who underwent endoscopic management (EM) and 74 who were observed without EM (NO-EM). FNOM of overall NOM was 20%, including 30% of NO-EM and 9% of EM. There was no significant difference in FNOM for NO-EM versus EM for grade I, however, a significant decrease in FNOM was noted with the addition of EM for grade II and III. EM was a statistically significant independent risk factor. Regular follow-up of 1 year showed that, for patients from grade I to III, 53 patients (42%) from operative management (OM) and 34 patients (46%) of the NO-EM developed various pancreatic-related complications, while only 15 patients (26%) of the EM developed such complications, and the difference was significant.

CONCLUSION

Application of strictly defined selection criteria for NOM and EM in patients with blunt pancreatic injury resulted in one of the lowest FNOM rates (9%) and pancreatic-related complications incidence (25%). Selective application of EM for hemodynamically stable patients with blunt pancreatic injury will extend the indications for, and improve success of NOM.

Diagnosis and treatment of traumatic pancreatic injuries

Pancreatic trauma accounted for 1%-5% of all blunt abdominal injuries and 12% of penetrating abdominal injuries. Although pancreatic trauma is uncommon, its mortality is high. Early accurate diagnosis, selection of suitable means of treatment based on the degree of injury, and management of complications are issues that should be stressed in the treatment of pancreatic trauma. This article discusses the clinical diagnosis, treatment and complications of pancreatic trauma.

Outcomes of hemodynamically stable patients with pancreatic injury after blunt abdominal trauma

BACKGROUND

To date there is no systematical report about blunt pancreatic injury focused on hemodynamically stable patients. This study reports on our experience in this rare subgroup at a tertiary referral hospital.

METHODS

A total of 58 adult patients were identified during a 10-year period and their clinical data were analyzed. Injury to the main pancreatic duct (MPD) was basically confirmed by pancreatography or surgical findings.

RESULTS

MPD disruption was confirmed in 36 patients (62%) and was more frequent in the pancreatic neck and body. The median time from trauma to confirmation was 14 days [interquartile range (IQR) 3-23 days] including time from admission to confirmation of 10.5 days [IQR 3-20 days]. Patients with MPD injury showed higher injury severity score, more frequent pancreas-specific complications and longer hospital stays. The sensitivity and specificity of initial computed tomography (CT) for MPD injury were 63.9% (23/36) and 81.8% (18/22), respectively. The mortality rate was 7%, and all deaths were directly attributed to pancreatic injury. Complications occurred in 22 patients (37%) and 17 developed during hospitalization. Time from trauma to confirmation of MPD disruption (odds ratio 1.132; 95% confidence interval 1.021-1.255, P=0.019) was the only independent factor associated with unfavorable events among patients with high-grade injury.

CONCLUSIONS

MPD injury was not infrequent in hemodynamically stable patients. Physicians were more responsible for the delay in diagnosis of MPD disruption, which was primarily associated with adverse outcomes. A rapid, multidisciplinary approach may lead to better outcomes in hemodynamically stable patients with blunt pancreatic injury.

Impact of a defined management algorithm on outcome after traumatic pancreatic injury

BACKGROUND

The optimal management of pancreatic injuries, specifically with respect to defining ductal integrity, remains controversial. Our previous experience suggested that decisions based on probability of ductal injury might improve outcome. Consequently, a management algorithm (ALG) was developed and implemented. The purpose of this study was to evaluate the impact of this ALG on outcomes.

METHODS

Consecutive patients more than 13 years with pancreatic injuries subsequent to the development of the ALG were evaluated. Pancreatic injuries were defined as proximal or distal and ductal injuries classified as definite, high, low, or indeterminate (IND) probability. Pancreas-related morbidity (fistula, abscess, and pseudocyst) and mortality were recorded. Patients managed by the ALG were compared with the previous study (PS).

RESULTS

In all, 245 patients were identified; 35 died within 12 hours and were excluded. Demographics and severity of shock (24-hour transfusions) were similar between groups. Pancreas-related morbidity for proximal injuries was 13.8% in the ALG group and 13.5% in the PS (p = 0.948). Pancreas-related morbidity was significantly reduced in the ALG group for distal injuries requiring drainage alone (11% vs. 25%, p = 0.05) and for distal injuries requiring resection + drainage (26% vs. 58%, p = 0.003) when compared with the PS. There was no pancreas-related mortality in the ALG group (1.6% in the PS group, p = 0.065).

CONCLUSIONS

Adherence to a defined ALG simplified the management of traumatic pancreatic injuries and contributed to a reduction in both pancreas-related morbidity and mortality. The majority of all proximal pancreatic injuries can be treated with drainage alone. For distal injuries, a clinical decision based on defined parameters and suspicion of ductal injury dictates definitive management.

Evolving management of pancreatic injury

PURPOSE OF REVIEW

In this study we present a concise review of the evolving management of traumatic injury to the pancreas, including diagnostic approaches and options for operative and nonoperative intervention.

RECENT FINDINGS

New diagnostic adjuncts can be used for the evaluation of injury to the pancreas and pancreatic duct. Magnetic resonance cholangiopancreatography and endoscopic retrograde cholangiopancreatography (ERCP) are used as diagnostic modalities for duct evaluation. ERCP can be therapeutic with sphincterotomy and/or stenting for duct disruption. Computed tomography scan is the initial imaging study of choice for pancreatic injury, but is also used for drainage of pancreatic abscesses or pseudocysts.

SUMMARY

Nonoperative management of solid organ injuries is the recommended treatment in hemodynamically stable patients. This strategy is now being successfully applied to pancreatic injuries in specific situations. However, the mainstays of pancreatic injury remain the same. The identification of pancreatic duct injury is the top priority. Management includes distal resection, debridement, and closed suction drainage of pancreatic injuries.
