Management and outcomes of peripancreatic fluid collections and pseudocysts following non-operative management of pancreatic injuries in children

Pancreatic Cystic Lesions in Children: A Comprehensive Scoping Review

OBJECTIVE

Pediatric pancreatic cystic lesions (PPCLs) are uncommon and differ from adult pancreatic cystic lesions. Literature is limited on the etiologies, evaluation, and management of PPCL. A multidisciplinary working group formed to provide a comprehensive description of PPCL and recommend best available evidence-based evaluation and management.

MATERIALS AND METHODS

The PPCL working group performed a scoping review by 2 methods: 1) a targeted literature review to describe PPCL and 2) a systematic literature review for management recommendations for PPCL. The systematic review was completed using a 2-stage sifting approach: title and abstract screening followed by a full text review.

RESULTS

One hundred thirty-one studies were included in the systematic review and an additional 20 were included in the targeted search to complete a comprehensive list of PPCL. Five neoplastic PPCL and 10 nonneoplastic PPCL were identified, and prevalence of different cystic lesions differs widely in adults and children. Recommendations on evaluation and management of PPCL are presented based on best available evidence.

CONCLUSIONS

We present a comprehensive review and evidence-based management recommendations with management algorithms for pediatric pancreatic cystic lesions. Given the rarity of many of these entities, this review also highlights many aspects of PPCL, which are not adequately described in the current literature.

Prospective Outcomes of Standardized Non-operative Management of Pancreatic Trauma With Ductal Injury in Children: Less is More

BACKGROUND

Traumatic pancreatic laceration with ductal injury in children can be managed non-operatively (NOM); however, variable management affects outcomes. We hypothesized that a standardized management approach with early feeding and limited resource utilization is safe and improves outcomes.

METHOD

Prospective, multicenter study of 13 pediatric trauma centers (2018-2022). Children with blunt pancreatic trauma with ductal injury were managed per a standard NOM pathway. Outcomes were compared to a historical NOM cohort with variable management.

RESULTS

Of 22 patients, the median age was 7.5 years (range 1-14 years). Low-fat diet was started at median 4 days [IQR 2-7] and median hospital stay was 8 days [IQR 4-10]. One patient failed NOM and underwent distal pancreatectomy. Of the rest, most (17/21, 81%) had early recovery and discharged in median 6 days [IQR 4-8.25] while 4 (19%) had prolonged recovery (median stay 24 days, IQR 19.8-30.5) and higher peri-pancreatic cyst development (early 23.5% vs prolonged 75%,p = 0.05). Pancreatic ascites at presentation correlated with cyst development (p < 0.0001). Endoscopic stent (optional) was placed in 33% and did not prevent cyst development. Delayed exocrine pancreatic insufficiency was noted in 1 patient. Compared to the historic cohort (32 patients), TPN use was lower (pre-protocol 56% vs post 23%, p = 0.02), days to diet was shorter (pre-protocol 7 vs post 4; p = 0.03), and cyst development was lower (pre-protocol 81% vs post 33%, p < 0.001).

CONCLUSION

Children with traumatic pancreatic ductal injury can be safely managed per the PTS NOM clinical pathway and most recover rapidly. Pancreatic ascites may predict pseudocyst formation.

The Diagnosis and Management of Pediatric Blunt Abdominal Trauma-A Comprehensive Review

Blunt abdominal trauma in childhood has always been full of diagnostic and therapeutic challenges that have tested the clinical and radiological skills of pediatric surgeons and radiologists. Despite the guidelines and the studies carried out so far, to this day, there is no absolute consensus on certain points of view. Around the world, a paradigm shift towards non-operative treatment of hemodynamically stable children, with low complication rates, is noticeable. Children with blunt abdominal trauma require a standardized methodology to provide the best possible care with the best possible outcomes. This comprehensive review systematizes knowledge about all aspects of caring for children with blunt abdominal trauma, from pre-hospital to post-hospital care.

Management of Pediatric Solid Organ Injuries

Solid organ injury (SOI) is common in children who experience abdominal trauma, and the management of such injuries has evolved significantly over the past several decades. In 2000, the American Pediatric Surgical Association (APSA) published the first societal guidelines for the management of blunt spleen and/or liver injury (BLSI), advocating for optimized resource utilization while maintaining patient safety. Nonoperative management (NOM) has become the mainstay of treatment for SOI, and since the publication of the APSA guidelines, numerous groups have evaluated how invasive procedures, hospitalization, and activity restrictions may be safely minimized in children with SOI. Here, we review the current evidence-based management guidelines in place for the treatment of injuries to the spleen, liver, kidney, and pancreas in children, including initial evaluation, inpatient management, and long-term care, as well as gaps that exist in the current literature that may be targeted for further optimization of protocols for pediatric SOI.

Blunt pancreatic injury in children: Lessons from 11-year experience in a pediatric center

OBJECTIVE

To study the diagnosis, management strategies, and outcomes of pediatric patients with blunt pancreatic injury.

METHODS

The clinical data of patients with blunt pancreatic injury at Children's Hospital, Zhejiang University School of Medicine from January 2011 to September 2022 were collected and analyzed retrospectively.

RESULTS

A total of 51 patients were enrolled. According to the American Association for the Surgery of Trauma (AAST) classification of pancreatic injury, 41 patients were categorized in the low-grade and nine in the high-grade groups. On admission, serum amylase and lipase levels in the high-grade group were significantly higher than in the low-grade group (P = 0.025 and P = 0.021, respectively). The peak levels of serum amylase and lipase in the high-grade group were considerably higher than in the low-grade group (P = 0.017 and P = 0.038, respectively). Two patients received surgical treatment, but none experienced pancreatectomy. The remaining 49 patients were successfully treated with conservative methods. The incidence of pancreatic pseudocysts in patients was 47.1% (24/51), and half required external drainage.

CONCLUSION

Conservative management is safe for most children with blunt pancreatic injury, surgical intervention should be adopted in patients with hemodynamic instability or multiple organ failure.

Asparaginase-associated Pancreatitis Complicated by Pancreatic Fluid Collection Treated with Endoscopic Cistogastrostomy in Pediatric Acute Lymphoblastic Leukemia: A Case Report and Systematic Review of the Literature

Asparaginase-associated pancreatitis complicates 2-10% of patients treated for acute lymphoblastic leukemia, causing morbidity and discontinuation of asparaginase administration. Among acute complications, pancreatic fluid collections can be managed conservatively, but intervention is indicated when associated with persistent insulin therapy need and recurrent abdominal pain. Endoscopic treatment has become the standard approach in adult patients, with increasing favorable evidence in children. This work compares the characteristics of a pediatric oncology patient treated at our institution with reported literature experiences, showing feasibility, safety and effectiveness of endoscopic approach.

Paediatric pancreatic trauma in North Queensland: a 10-year retrospective review

PURPOSE

To establish the incidence of pancreatic trauma in North Queensland to the region's only tertiary paediatric referral centre, and to determine the patient's outcomes based on their management.

METHODS

A single centre, retrospective cohort study of patients < 18 years with pancreatic trauma from 2009 to 2020 was performed. There were no exclusion criteria.

RESULTS

Between 2009 and 2020 there were 145 intra-abdominal trauma cases, 37% from motor vehicle accidents (MVA), 18.6% motorbike or quadbike, and 12.4% bicycle or scooter accidents. There were 19 cases of pancreatic trauma (13%), all from blunt trauma and with associated injuries. There were 5 AAST grade I, 3 grade II, 3 grade III, 3 grade IV injuries, and 4 with traumatic pancreatitis. Twelve patients were managed conservatively, 2 were managed operatively for another reason, and 5 were managed operatively for the pancreatic injury. Only 1 patient with a high grade AAST injury was successfully managed non-operatively. Complications included pancreatic pseudocyst (n = 4/19; 3 post-op), pancreatitis (n = 2/19; 1 post op), and post-operative pancreatic fistula (POPF) (n = 1/19).

CONCLUSION

Due to North Queensland's geography, diagnosis and management of traumatic pancreatic injury is often delayed. Pancreatic injuries requiring surgery are at high risk for complications, prolonged length of stay, and further interventions.

Surgical drainage procedures for paediatric chronic pancreatitis: a scoping review

Paediatric chronic pancreatitis (CP) is a relatively rare entity, but it can be accompanied by debilitating complications such as pseudocysts, chronic pain and pancreatic duct obstruction. Surgical drainage procedures, such as pancreaticojejunostomy or cystogastrostomy/jejunostomy to address these complications may be required; however, there is a paucity of evidence as to the efficacy and long-term outcomes of these operations in the paediatric population. A scoping review of contemporary (post-2000) studies detailing surgical pancreatic drainage procedures performed in children (< 18 years) was undertaken. After screening, 24 case series detailing a total of 248 patients met the inclusion criteria. Longitudinal pancreaticojejunostomy and cystogastrostomy were the most common surgical procedures performed in children with CP and pseudocysts, respectively. Overall generally favourable outcomes were reported, but all studies were considered to have a high risk of bias. Operative management for paediatric CP is infrequently required; therefore, large prospective studies or trials focusing on this population are infeasible, limiting the best available evidence on the topic to case series, level IV. Recommendations to improve the quality of surgical care in the paediatric CP population could include centralisation and the formation of registries to allow accurate long-term follow-up.

Massive gastrointestinal haemorrhage caused by pancreatic pseudocyst complicated with Dieulafoy's disease in a child: A case report and review of the literature

BACKGROUND

Pancreatic pseudocyst (PPC) with massive gastrointestinal bleeding is rare, especially in children. Inadvertent intraoperative examination and damage to the gastric mucosa and malformed blood vessels by the fluid content of PPC can lead to massive bleeding, which may endanger the patient's life.

CASE PRESENTATION

Here, we present a case of an 8-year-old boy who was diagnosed with a massive gastrointestinal haemorrhage caused by PPC complicated with Dieulafoy's disease. At his first admission, his complaint was being hit to the stomach by the handlebar while riding bicycle 24 h before admission. After being hospitalized, he was diagnosed with pancreatic injury by abdominal CT. Conservative treatment lasted for 1 month in the Department of Pediatric Surgery. Then, a pancreatic pseudocyst was formed. Under the guidance of ultrasonic endoscopy, cyst puncture and drainage of pseudocysts through the gastric wall were performed. Unexplained hematemesis occurred 8 days after surgery. Emergency gastroscopy was performed, and abnormal submucosal vascular haemorrhage was found at the gastric fundus. Gastric Dieulafoy's disease was diagnosed. The boy underwent gastroscopic titanium clipping of abnormal arteries. He had no complications during the 3-month follow-up. Then, the patient returned to the hospital, and the stent was removed under endoscopy. No bleeding was found, and the patient was discharged. The patient recovered smoothly and was followed up for half a year without any complications, and hematological indicators were normal.

CONCLUSION

Endoscopic ultrasonography-guided gastric puncture and internal drainage of cysts is a safe and effective surgical method for the treatment of pancreatic pseudocysts. However, at the same time, it is necessary to thoroughly and carefully explore the stomach cavity to prevent adverse consequences caused by a missed diagnosis of gastric Dieulafoy's disease or other abnormal abnormalities.

Minimally invasive surgery of the pancreas: a narrative review of current practice

Minimally invasive surgery has moved from the fringe of pediatric surgery to the mainstream to address a variety of problems. Pancreatic pathology, though uncommon and complex, is frequently amenable to laparoscopic intervention. Indications for pediatric pancreatic operative intervention includes trauma, congenital hyperinsulinemia and neoplasm. Children may require distal pancreatectomy, subtotal pancreatectomy, enucleation, lateral pancreaticojejunostomy and pancreaticoduodenectomy. Of these operations, all but pancreaticoduodenectomy have been successfully described in children using a minimally invasive approach. Traumatic transection of the main pancreatic duct may require operative intervention if endoscopic techniques are unsuccessful. Distal pancreatectomy has been successfully utilized in this circumstance. Additionally, near total pancreatectomy may also be performed laparoscopically although successful reports are limited. Enucleation, especially with the use of intraoperative ultrasound may avoid a large laparotomy for isolated benign masses. Finally, chronic pancreatitis resulting in a dilated main pancreatic duct may benefit from a lateral pancreaticojejunostomy. This operation has also successfully been performed in children. Included is a review of pediatric pancreatic minimally invasive operations paired with corresponding pathology.

Endoscopic cystogastrostomy: Still a viable option in children with symptomatic pancreatic fluid collection

BACKGROUND/OBJECTIVES

Endoscopic transmural drainage is the preferred method of drainage of pancreatic fluid collections (PFCs) in adults; however, there is scant literature in children. We analyzed our experience of 33 endoscopic cystogastrostomies done in 29 children to find its efficacy and safety.

METHODS

We retrospectively analyzed the prospectively collected database of 31 consecutive children (<18 years) who underwent endoscopic cystogastrostomy from June 2013 to December 2017. The procedure was done using the standard technique with an adult duodenoscope. Data related to clinical details, technical success, complications and follow-up were collected.

RESULTS

The median age was 14 (3-17) years (22 males). Indications were early satiety in 28 (90%), vomiting in 15 (48%), and duodenal obstruction and infected pseudocyst in 2 children each. Etiology includes acute pancreatitis 22, post-traumatic 4 and chronic pancreatitis 5. The procedure was successful in 29 of 31 (93.5%) children with no mortality. Adverse events happened in four cases (12.9%); two infections, another with bleeding and another with pneumoperitonium, both of which resolved spontaneously. Incidents (minor bleeding) were noted in 6 (19%). Stents were removed in 26 (90%) after 12 (7-20) weeks and got spontaneously migrated out in 3 (10%) cases. Over a median follow-up of 26 (5-48) months, 26 (90%) had no recurrence of pseudocyst and 3 (10%) had recurrence of a small, asymptomatic pseudocyst.

CONCLUSIONS

Endoscopic cystogastrostomy is a safe and effective method of draining bulging PFCs in children. The procedure carries acceptable morbidity with minimal recurrence. In younger children it may be the preferred method of drainage of PFCs.

Endoscopic cyst gastrostomy for traumatic pancreatic pseudocysts in children: a case series

Background

Pancreatic pseudocysts may develop after high-grade pancreatic injuries in children. Many resolve without intervention, and the management of symptomatic pseudocysts that persist remains controversial, with various open, percutaneous and laparoscopic approaches to intervention described. Successful endoscopic cyst gastrostomy has been reported in children with pancreatic pseudocysts of mixed etiology.

Methods

The trauma registry and electronic medical record of a level 1 pediatric trauma center were queried for children with a symptomatic pseudocyst following pancreatic trauma over a 12-year period, from 2008 to 2019.

Results

We describe a case series of five consecutive children with persistent symptomatic pancreatic pseudocysts following blunt abdominal trauma all successfully treated with endoscopic cyst gastrostomy.

Discussion

Endoscopic cyst gastrostomy appears to be safe and effective in the management of symptomatic pancreatic pseudocysts in children following pancreatic trauma.
