Surgical outcomes of pancreaticoduodenal injuries in children

Management of pancreatic and duodenal trauma in childhood: a university hospital experience over a 10-year period

PURPOSE

Duodenal/pancreatic injuries occur in less than 10% of intra-abdominal injuries in pediatric blunt trauma. Isolated duodenal/pancreatic injuries occur in two-thirds of cases, while combined injuries occur in the remaining. This study aimed to investigate pediatric patients with pancreatic and duodenal trauma.

METHODS

Data from 31 patients admitted to Atatürk University, Medical Faculty, Department of Pediatric Surgery for pancreatic/duodenal trauma between 2010 and 2019 were retrospectively analyzed. Age/gender, province of origin, duration before hospital admission, trauma type, injured organs, injury severity, diagnostic and therapeutic modalities, complications, hospitalization duration, blood transfusion requirement, and mortality rate were recorded.

RESULTS

Twenty-four patients were male, and 7 were female. The mean age was 9 years. The leading cause was bicycle accidents, with 12 cases, followed by traffic accidents/bumps, with 7 cases each. Comorbid organ injuries accompanied 18 cases. Duodenal trauma was most commonly accompanied by liver injuries (4/8), whereas pancreatic injury by pulmonary injuries (7/23). Serum amylase at initial hospital presentation was elevated in 83.9% of the patients. Thirty patients underwent abdominal CT, and FAST was performed in 20. While 54.8% of the patients were conservatively managed, 45.2% underwent surgery.

CONCLUSION

Because of the anatomical proximity of the pancreas and the duodenum, both organs should be considered being co-affected by a localized trauma. Radiologic confirmation of perforation in duodenal trauma and an intra-abdominal pancreatic pseudocyst in pancreatic trauma are the most critical surgical indications of pancreaticoduodenal trauma. Conservative management's success is increased in the absence of duodenal perforation and cases of non-symptomatic pancreatic pseudocyst.

Pancreaticoduodenectomy for trauma in an adolescent female with complex pancreatic and duodenal injuries: Case report and review of the literature

Background

We present a successful staged surgical repair of an adolescent who sustained a high grade combined pancreaticoduodenal injury following a high-speed motor vehicle collision.

Methods

We discuss our case as well as provide a thorough literature review made on databases such as PubMed, Google Scholar, and Embase.

Summary

A fifteen-year-old female presented after a motor vehicle collision with abdominal pain and imaging suggestive of pancreatic and duodenal injuries. Emergent exploratory laparotomy confirmed a transection of the pancreatic neck in addition to disruption of the second portion of the duodenum. She sustained other injuries including an injury to the portal vein and a right colonic perforation. A damage control strategy was employed, and the patient underwent duodenal repair, wide drainage of the pancreatic injury, primary portal vein repair, right hemicolectomy, and temporary abdominal closure using negative pressure wound dressing placement. She remained stable overnight in the ICU and was taken back to the operating room for a pylorus-preserving pancreaticoduodenectomy with a hepatobiliary surgeon the following afternoon. The patient required additional surgery for fixation of an unstable vertebral fracture but was discharged to inpatient rehab within two weeks of presentation. She did not require TPN, and the only long-term sequelae have been admissions for acute uncomplicated pancreatitis that have been treated medically.

Conclusion

Combined pancreatic and duodenal injury in the pediatric population is uncommon. We discuss our case of a patient requiring a pancreaticoduodenectomy. Despite postoperative pancreatitis and limited information in this field, we believe we provided the optimal surgical care, and this is a potential area for future investigation.

Operative versus non-operative management of blunt pancreatic trauma in children: Systematic review and meta-analysis

AIM

Blunt abdominal trauma is the major cause of abdominal injury in children. No clear guidelines exist for the initial management of blunt pancreatic trauma in children. The aim of this study was to perform a systematic review and meta-analysis of initially non-operative versus initially operative treatment in children with blunt pancreatic injury.

METHODS

Studies including children (<18 years) with blunt pancreatic injuries published in any language after year 1990 were included. Total of 849 studies were identified by searching PubMed, Scopus, CINAHL and Cochrane Database. After review, 42 studies met inclusion criteria and were included in this systematic review. There were 1754 patients, of whom 1095 were initially managed non-operatively (NOM), and 659 operatively (OM). Primary outcome was non-operative management success rate, and secondary outcomes were mortality, complications (including specifically pseudocysts and pancreatic fistulas), percent of patients and days on total parenteral nutrition (TPN), length of hospital stay and readmissions.

RESULTS

There was no difference in mortality between NOM and OM groups. The incidence of pseudocysts was significantly higher in NOM group compared to OM (P<0.001), especially for AAST grade III or higher (P<0.00001). Overall incidence of pancreatic fistulas was significantly lower for NOM group (p = 0.02) but no difference was observed for AAST grades III or higher (p = 0.49). There was no difference in the length of hospital stay (P = 0.31). Duration of total parenteral nutrition was not different for all AAST grades (P = 0.35), but was significantly shorter for OM group for AAST grades III and higher (p = 0.0001). There was no overall difference in readmissions (P = 0.94). Overall success rate of initial non-operative treatment was 87%.

CONCLUSIONS

Most patients with pancreatic trauma can initially be treated non-operatively, while early surgical treatment may benefit patients with lesions of the main pancreatic duct. ERCP offers both highly accurate diagnosis and potential treatment of ductal injuries.

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.

Clinical update on management of pancreatic trauma

BACKGROUND

Pancreatic injury is rare and optimal diagnosis and management is still debated. The aim of this study was to review the existing data and consensus on management of pancreatic trauma.

METHODS

Systematic literature review until May 2018.

RESULTS

Pancreas injury is reported in 0.2-0.3% of all trauma patients. Severity is scored by the organ injury scale (OIS), with new scores including physiology needing validation. Diagnosis is difficult, clinical signs subtle, and imaging by ultrasound (US) and computed tomography (CT) non-specific with <60% sensitivity for pancreatic duct injury. MRCP and ERCP have superior sensitivity (90-100%) for detecting ductal disruption. Early ERCP with stent is a feasible approach for initial management of all branch-duct and most main-duct injuries. Distal pancreatectomy (±splenectomy) may be required for a transected gland distal to the major vessels. Early peripancreatic fluid collections are common in ductal injuries and one-fifth may develop pseudocysts, of which two-thirds can be managed conservatively. Non-operative management has a high success rate (50-75%), even in high-grade injuries, but associated with morbidity. Mortality is related to associated injuries.

CONCLUSION

Pancreatic injuries are rare and can often be managed non-operatively, supported by percutaneous drainage and ductal stenting. Distal pancreatectomy is the most common operative procedure.
