Outcomes following operative vs. non-operative management of blunt traumatic pancreatic injuries: a retrospective multi-institutional study.

BackgroundTraumatic pancreatic injuries are rare, and guidelines specifying management are controversial and difficult to apply in the acute clinical setting. Due to sparse data on these injuries, we carried out a retrospective review to determine outcomes following surgical or non-surgical management of traumatic pancreatic injuries. We hypothesize a higher morbidity and mortality rate in patients treated surgically when compared to patients treated non-surgically.MethodsWe performed a retrospective review of data from four trauma centers in New York from 1990–2014, comparing patients who had blunt traumatic pancreatic injuries who were managed operatively to those managed non-operatively. We compared continuous variables using the Mann-Whitney U test and categorical variables using the chi-square and Fisher’s exact tests. Univariate analysis was performed to determine the possible confounding factors associated with mortality in both treatment groups.ResultsTwenty nine patients were managed operatively and 32 non-operatively. There was a significant difference between the operative and non-operative groups in median age (37.0 vs. 16.2 years, P = 0.016), grade of pancreatic injury (grade I; 30.8 vs. 85.2%, P value for all comparisons <0.0001), median injury severity score (ISS) (16.0 vs. 4.0, P = 0.002), blood transfusion (55.2 vs. 15.6%, P = 0.0012), other abdominal injuries (79.3 vs. 38.7%, P = 0.0014), pelvic fractures (17.2 vs. 0.00%, P = 0.020), intensive care unit (ICU) admission (86.2 vs. 50.0%, P = 0.003), median length of stay (LOS) (16.0 vs. 4.0 days, P <0.0001), and mortality (27.6 vs. 3.1%, P = 0.010).ConclusionsPatients with traumatic pancreatic injuries treated operatively were more severely injured and suffered greater complications than those treated non-operatively. The greater morbidity and mortality associated with these patients warrants further study to determine optimal triage strategies and which subset of patients is likely to benefit from surgery.

Management of adult pancreatic injuries: A practice management guideline from the Eastern Association for the Surgery of Trauma.

Traumatic injury to the pancreas is rare but is associated with significant morbidity and mortality, including fistula, sepsis, and death. There are currently no practice management guidelines for the medical and surgical management of traumatic pancreatic injuries. The overall objective of this article is to provide evidence-based recommendations for the physician who is presented with traumatic injury to the pancreas. The MEDLINE database using PubMed was searched to identify English language articles published from January 1965 to December 2014 regarding adult patients with pancreatic injuries. A systematic review of the literature was performed, and the Grading of Recommendations Assessment, Development and Evaluation framework was used to formulate evidence-based recommendations. Three hundred nineteen articles were identified. Of these, 52 articles underwent full text review, and 37 were selected for guideline construction. Patients with grade I/II injuries tend to have fewer complications; for these, we conditionally recommend nonoperative or nonresectional management. For grade III/IV injuries identified on computed tomography or at operation, we conditionally recommend pancreatic resection. We conditionally recommend against the routine use of octreotide for postoperative pancreatic fistula prophylaxis. No recommendations could be made regarding the following two topics: optimal surgical management of grade V injuries, and the need for routine splenectomy with distal pancreatectomy. Systematic review, level III.

Challenges in early detection of pancreatic cancer

Pancreatic trauma occurs in 0.2% of patients with blunt trauma and 1–12% of patients with penetrating trauma. Traumatic pancreatic injuries are characterised by high morbidity and mortality, which further increase with delayed diagnoses. The diagnosis of pancreatic trauma is challenging. Signs and symptoms can be non-specific or even absent.A critical review of studies reporting the management and outcomes of pancreatic trauma was performed.The management of pancreatic trauma depends on the haemodynamic stability of the patient, the degree and location of parenchymal injury, the integrity of the main pancreatic duct, and the associated injuries to other organs. Nevertheless, the involvement of the main pancreatic duct is the most important predictive factor of the outcome. The majority of pancreatic traumas are managed by medical treatment (parenteral nutrition, antibiotic therapy and somatostatin analogues), haemostasis, debridement of devitalised tissue and closed external drainage. If a proximal duct injury is diagnosed, endoscopic transpapillary stent insertion can be a viable option, while surgical resection by pancreaticoduodenectomy is restricted to an extremely small number of selected cases. Injuries of the distal parenchyma or distal duct may be managed with distal pancreatectomy with spleen preservation. At the pancreatic neck, when pancreatic transection occurs without damage to the parenchyma, a parenchyma-sparing procedure is feasible.The management of pancreatic injuries is complex and often requires a multidisciplinary approach. Here, we propose a management algorithm that is based on parenchymal damage and the site of duct injury.

Magnitude, Severity, and Outcome of Traumatic Pancreatic Injury at a Level I Trauma Center in India.

Pancreatic injury is an uncommon and frequently missed injury in abdominal trauma patients. However, missed pancreatic injury is associated with significant morbidity and mortality. This study was conducted to know the burden of pancreatic injury and its outcome in our setup. A retrospective analysis of 53 patients with pancreatic injury from January 2008 through March 2012 at the Jai Prakash Narayan Apex Trauma Center (JPNATC), All India Institute of Medical Sciences (AIIMS), New Delhi. Pancreatic injuries were present in 1.18% of all trauma admissions. Blunt trauma to the abdomen (n = 49, 92.45%) due to road traffic injury (n = 38, 71.70%) was the most common mechanism of injury. Isolated pancreatic injury was present in eight (15.09%) patients. Grade III pancreatic injury (n = 25, 47%) was the most common. Of these patients, 18.86% were managed nonoperatively and 81.13% were managed operatively. Among the operatively managed patients (n = 43), 74.4% were operated due to pancreatic injury and 25.5% were operated due to associated injuries. Distal pancreatectomy with or without spleen preservation (n = 25) was the most common operative procedure done. Three out of five patients of Whipple operation for pancreatic injury died. Pancreatic injury was associated with complications in 43.40% and death in 20% (n = 11). Pancreatic injury is rare, but delay in diagnosis of pancreatic injury has been associated with higher morbidity and mortality. Low-grade pancreatic injury with intact main pancreatic duct (MPD) could be successfully managed nonoperatively, whereas in high-grade pancreatic injury, an operative intervention is invariably necessary. Distal pancreatectomy with spleen preservation is a desirable goal whenever possible for distal transaction of the pancreas. Whipple resection should be reserved only for hemodynamically stable patients with complex pancreaticoduodenal injury and is associated with high mortality.

Conservative endoscopic management for pancreatic trauma

Traumatic pancreatic injuries are rare: their severity correlates with main pancreatic duct involvement. We report the case of a 5-year-old child who presented with complete disruption of the main pancreatic duct, treated successfully with an endoscopically inserted double pigtail stent.

Operative vs Nonoperative Management of Pediatric Blunt Pancreatic Trauma: Evaluation of the National Trauma Data Bank

Traumatic pancreatic injury is associated with significant morbidity and mortality. We evaluated the differences in outcomes among children with blunt pancreatic injuries managed operatively and nonoperatively. The National Trauma Data Bank was evaluated from 2002 to 2011. Patients less than18 years of age with blunt pancreatic injuries and Abbreviated Injury Scale (AIS) scores ≥ 3 were identified. Patients were divided into nonoperative (NO), operative (O), and delayed operative (DO; operation performed 48 hours or more after admission) groups. Outcomes evaluated were total length of stay (LOS), ICU use/LOS, complications, and death. Univariate comparisons were performed using Fisher's exact and Kruskal-Wallis rank tests. Multivariable analyses were performed using robust regression and logistic regression. There were 424 cases analyzed. Mean (± SD) age was 10.6 ± 5.3 years, and mean Injury Severity Score (ISS) was 23.4 ± 13.4. Operative groups differed by age (p= 0.002), AIS severity (p= 0.04), and concomitant head injury (p= 0.01), but were similar with regard to sex, race, and ISS. Length of stay was significantly higher in the DO group compared with the NO or O groups; the NO group had the lowest LOS (covariate-adjusted: 18.7 days vs 11.8 days, p < 0.001 and 12.6 days, p < 0.001, respectively) and infection rates (10.2% vs 1.6% and 6.2%, respectively, p= 0.04). The ICU LOS was greatest in the DO group (vs NO, p= 0.03; O, p= 0.29), as was the likelihood of ICU use (vs NO, p= 0.02; O, p= 0.75). Groups did not differ with respect to outcomes including death (p= 0.94) and overall complication rate (p= 0.63). Overall, children managed nonoperatively have equivalent or better outcomes when compared with operative and delayed operative management in regard to death, overall complications, LOS, ICU LOS, and ICU use.

Image-guided prediction of pseudocyst formation in pediatric pancreatic trauma

BackgroundTo determine if there is an effective alternative to the current standard of computed tomography (CT) grading of pediatric pancreatic injuries. We hypothesized that the Wong grading scale, which is based on the depth and location of the pancreatic laceration, is more predictive of pseudocyst formation than the American Association for the Surgery of Trauma (AAST) scale after nonoperative management of traumatic pancreatic injury in children. Materials and methodsA retrospective review of children admitted for pancreatic trauma to two level 1 pediatric trauma centers between 2000 and 2012 was conducted. Patients who underwent primary operation were excluded. Initial CT scans were reviewed by two radiologists blinded to clinical outcomes, and injury grades from both scales were assigned. The primary outcome was pseudocyst formation. ResultsFifty-three patients (ages 7 mo–17 y) were included. As per the Wong scale, pseudocysts occurred in 0/20 patients with grade A injuries, 2/17 (12%) with BI/CI injuries, and 9/15 (60%) with BII/CII injuries. Using the AAST scale, pseudocysts developed in 2/27 (7%) patients with grade I/II injuries, 7/20 (35%) patients with III/IV/V injuries, and 1/6 (17%) patients with a scan that was indeterminate between grades II and III. Positive Predictive value, negative predictive value, sensitivity, and specificity for pseudocyst formation were all higher using the Wong scale (AAST/Wong: Positive Predictive value 42%/50%, negative predictive value 91%/94%, sensitivity 80%/82%, and specificity 65%/77%). ConclusionsThe Wong CT grading scale may be superior to the AAST scale for early risk stratification for pseudocyst development after nonoperative management of pediatric pancreatic trauma; however, a larger study is needed for verification of these findings.

Pseudopancreatitis on computed tomography in a patient with isolated blunt head trauma: a case report

IntroductionComputed tomography is commonly used to exclude occult injuries in patients with trauma, but imaging can reveal findings that are of uncertain etiology or clinical significance. We present a case of unsuspected pancreatic abnormality in a female patient with trauma who sustained an isolated blunt head injury.Case presentationA 25-year-old female Caucasian patient sustained massive blunt and penetrating head trauma, secondary to a large object penetrating through the vehicle windshield. Based on the mechanism of injury and clinical evaluation, it was felt to be an isolated head injury. However, computed tomography of her abdomen revealed an occult, intra-abdominal finding of significant pancreatic enlargement and peripancreatic fluid. There was no computed tomography evidence of parenchymal pancreatic laceration. The appearance of her pancreas on computed tomography was identical to that of acute pancreatitis or low-grade pancreatic injury, but her clinical history and laboratory values were not consistent with this, hence the term ‘pseudopancreatitis’. Later surgery for organ donation confirmed diffuse pancreatic and peripancreatic edema, but no hematoma, contusion or other evidence for direct traumatic injury. This was an isolated intra-abdominal abnormality.ConclusionThe routine use of computed tomography in patients who have sustained trauma has led to increasing detection of unexpected findings. Clinical information such as mechanism of injury and blood work, along with careful evaluation of ancillary imaging findings (or lack of), is important for the provision of an appropriate differential diagnosis. We discuss the possible mechanism and differential diagnosis of an isolated pancreatic abnormality in the setting of non-abdominal trauma, which includes shock pancreas, overhydration, traumatic pancreatic injury and pancreatitis secondary to other etiologies.

Pancreatic trauma: A concise review

Traumatic injury to the pancreas is rare and difficult to diagnose. In contrast, traumatic injuries to the liver, spleen and kidney are common and are usually identified with ease by imaging modalities. Pancreatic injuries are usually subtle to identify by different diagnostic imaging modalities, and these injuries are often overlooked in cases with extensive multiorgan trauma. The most evident findings of pancreatic injury are post-traumatic pancreatitis with blood, edema, and soft tissue infiltration of the anterior pararenal space. The alterations of post-traumatic pancreatitis may not be visualized within several hours following trauma as they are time dependent. Delayed diagnoses of traumatic pancreatic injuries are associated with high morbidity and mortality. Imaging plays an important role in diagnosis of pancreatic injuries because early recognition of the disruption of the main pancreatic duct is important. We reviewed our experience with the use of various imaging modalities for diagnosis of blunt pancreatic trauma.

Dagnosis and treatment of traumatic pancreatic injury

Objective To investigate the diagnosis and treatment of traumatic pancreatic injury.Method The clinical data of 35 patients with traumatic pancreatic injury treated between January 1998and July 2010 at the General Hospital of Chinese PLA were retrospectively analyzed.Results There were 9 patients with Grade Ⅰ injury,7 with Grade Ⅱ injury,7 with Grade Ⅲ,7 with Grade Ⅳ,and 5 with Grade V injury,respectively.The diagnostic rate using CT before operation was 75.8％.8 patients with mild traumatic pancreatic injury received nonoperative treatment. 27 patients underwent open operation which included 15 simple external drainage of the pancreas area,2 distal pancreatectomy,5 Roux-en-Y pancraticojejunostomy,3 duodenal diverticulisation procedure,and 2 pancreaticoduodenectomy.After operation,there were 14 patients with pancreatic leakage,9 with intraabdominal infection,and 6 with intrabdominal bleeding.There were 3 patients with Grade Ⅳ and Grade V injuries who died of multiple organ failure or uncontrolled massive intraabdominal bleeding.Conclusions It was difficult to diagnose pancreatic injury before operation.CT was a suitable method to accurately diagnose severe traumatic pancreatic injury.Most minor pancreatic injury could be treated nonoperatively or by external drainage.The appropriate operation should be selected according to the extent and degree of the injuries basing on the principle of damage control in patients with major injuries.Pancreatic fistula,intraabdominal infection and bleeding were conrmon complications after operation.Multiple organ failure and massive bleeding were the main causes for mortality. Key words: Pancreas; Abdominal injuries; Diagnosis; Treatment; Postoperative complications

Laparoscopic Versus Open Distal Pancreatectomy in the Management of Traumatic Pancreatic Disruption

Traumatic pancreatic transection is uncommon. The role of laparoscopy in the setting of this injury has not been well described. Six large-volume pediatric trauma centers contributed patients <18 years of age who underwent a distal pancreatectomy for traumatic pancreatic transection from 2000 to 2010. Twenty-one patients without another indication for emergency laparotomy underwent a distal pancreatectomy for Grade III pancreatic injuries, of which 7 underwent laparoscopic distal pancreatectomy. Mean (±SD) age was 8.6±4.7 years, and 67% were male. There was no difference in the presence of other injuries between the two groups (43% in each group). Computed tomography revealed a transected pancreas in 85% of the laparoscopic patients and 75% of the open group (P=1.0). Mean operative time was 218±101 minutes with laparoscopy compared with 195±111 minutes with the open procedure (P=.7). Median duration of hospitalization was 6 days (range, 6-18 days) in the laparoscopic group compared with 11 days (range, 5-26 days) in the open group (P=0.3). Postoperative morbidity was not different between the two groups (57% versus 21% for laparoscopic versus open, P=.2). Laparoscopy is equivalent to open distal pancreatectomy in children with select traumatic pancreatic injuries.

Pancreatic Injury in Children: Review of 7 Cases and the Pertinent Literature

Treatment of blunt injury of the pancreas in children remains controversial. Some prefer non-surgical treatment, whereas others prefer surgical management in selected cases. This report reviews our management strategies of children with blunt pancreatic trauma and their outcomes. Medical records of 7 children with traumatic pancreatic injury were retrospectively analyzed in our institutions. In addition, we reviewed the pertinent literature. There were 2 males and 5 females with a median age of 7.6 years. Pancreatic injury was classified in 3 patients as grade I, in 2 patients as grade II, and in 2 patients as grade III (AAST). The two grade III children underwent ERCP preoperatively. ERCP showed injury to the main pancreatic duct in both of these patients, and emergency surgery was performed for both of them. These operative methods were spleen-preserving distal pancreatectomy and only drainage at the margin of the pancreas with non-resection, respectively. All 7 cases survived. ERCP is helpful for the diagnosis of suspected cases in pancreatic injury with grade III. In hemorrhagic shock state, appropriate surgical procedures with only drainage at the margin of the pancreas are useful for the treatment of pancreatic fistula in children.

Surgical experience and clinical outcome of traumatic pancreatic injury.

Backgrounds/AimsTraumatic pancreatic injury is rare and various surgical procedures can be applied according to the severity of injury. We reviewed our experience of pancreatic injury and investigated the clinical outcome.MethodsFifty-six patients were treated conservatively or with surgery for pancreatic injury at the Department of Surgery, Korea University Medical Center of Korea University College of Medicine from January 2001 to February 2012.ResultsForty-one men and 15 women were included (mean age, 32 years; range, 5-66 years). Twelve patients were hypotensive at admission. According to the American Association for the Surgery of Trauma grade, 15 patients were grade I, 16 were grade II, 10 were grade III, 13 were grade IV, and one patient was grade V. A total of 41 patients underwent exploratory surgery. Complications developed in 35 patients, and 19 patients demonstrated intra-abdominal abscesses associated with pancreatic leakage. Four mortalities occurred. More adult patients (n=42) required intensive care than that of pediatric patients (n=14) (p=0.03). However, more pediatric patients had hyperamylasemia at admission (p=0.023). A significantly higher proportion of patients in the hypotensive group had blunt abdominal injuries, associated extra-abdominal injuries, combined intra-abdominal injuries, longer ICU stays, and a higher mortality rate.ConclusionsAssociated intra-abdominal and extra-abdominal injuries are frequent in patients with traumatic pancreatic injury. Despite the complication rate, most patients recovered. Mortalities were associated with combined injuries being placed into bleeding, hypovolemic shock, and multiorgan failure.

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

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. 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). 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). 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.
