Etiology and classification of acute pancreatitis in children admitted to ICU using the Pediatric Sequential Organ Failure Assessment (pSOFA) score

BackgroundPediatric acute pancreatitis (AP) is rare but increasing. Severe AP is associated with higher morbidity and mortality. However, there are no universally accepted prognostic criteria for AP. MethodsThis retrospective study included children with AP admitted to an intensive care unit (ICU) of our tertiary pediatric center between January 2009 and December 2018. The severity of organ dysfunction in AP was assessed according to the modified Atlanta criteria using the Pediatric Sequential Organ Failure Assessment (pSOFA) and Computed Tomography Severity Index (CTSI). ResultsSeventy acute episodes of AP were evaluated in 55 children with primary pancreatitis. In addition, secondary AP was diagnosed in 15 patients originally admitted to ICU for different indications. Mild AP [no organ dysfunction, normal computed tomography (CT) finding] was the most prevalent (64/85 episodes in 49 children), followed by moderate AP (15 children; pSOFA 2-9 points, CTSI 3-4 points on admission). Severe AP (pSOFA 4-17 points, CTSI 6-10 points) was diagnosed in 6 children with traumatic or secondary AP. The most frequent etiologies of primary AP episodes were idiopathic (39%) and biliary (31%). Children with idiopathic AP had frequent relapses and comorbidities. Hereditary AP was typically mild, but presented with high pancreatic enzyme levels and recurrence rates. Admission at ICU and an interval without enteral nutrition (EN) were relatively short in drug-induced AP and relatively long in secondary and traumatic AP. Endoscopic retrograde cholangiopancreatography (ERCP) was performed in 13 patients with biliary AP and in 4 patients with traumatic AP. No AP-related death was observed. ConclusionpSOFA score accurately reflects the severity and prognosis of AP in children.

Prevalence, Natural History, and Outcome of Acute Fluid Collection and Pseudocyst in Children With Acute Pancreatitis.

Recent years have witnessed an increase in acute pancreatitis (AP) in children; however, the natural history of acute fluid collection (AFC) and pseudocyst is largely unknown. We evaluated the frequency, clinical characteristics, and natural history of pseudocysts in children with AP. Children with AP admitted at Sanjay Gandhi Postgraduate Institute of Medical Sciences from 2001 to 2011 were enrolled and studied until complete resolution. Subjects with inadequate follow-up, recurrent AP, and chronic pancreatitis were excluded. Of the 58 children (43 boys, median age 14 [1-18] years) with AP, 34 (58.6%) and 22 (38%) developed AFC and pseudocyst, respectively. No difference in age (12 [4-18] vs 13 [1-16] years), etiology (idiopathic 64% vs 47% and traumatic 27.2% vs 22.2%), and systemic complications (pulmonary [18% vs 11%], renal [22.7% vs 11%], and shock [13.6% vs 10%]) was observed between children with and without pseudocyst. A total of 11 of the 22 subjects with pseudocyst underwent drainage, the commonest symptom requiring drainage being gastric outlet obstruction [n = 5] and infection [n = 2]. The 11 of the 22 children with AP and pseudocyst (size 6.4 [3-14.4] cm) showed spontaneous resolution (disappearance [n = 9] and significant reduction in size [n = 2]) during 110 (25-425) days. Symptomatic pseudocysts requiring drainage were more often secondary to traumatic AP (6/6 vs 2/14 [idiopathic], P = 0.0007) than asymptomatic pseudocysts resolving spontaneously. Overall, only 26.4% (9/34) children with AFC required drainage because of symptomatic pseudocyst. Among children with AP, 58.6% developed AFC and 38% developed pseudocysts. Only patients with symptomatic pseudocyst need drainage, and asymptomatic pseudocyst can be safely observed irrespective of size and duration of collection.

A Case of Obstructive Jaundice Secondary to Traumatic Pancreatitis Treated with Percutaneous Transhepatic Biliary Drainage

Isolated pancreatic trauma and secondary obstructive jaundice in the pediatric population is unusual. Biliary tract obstruction can be a major cause of acute pancreatitis. We report a case of obstructive jaundice secondary to isolated traumatic acute pancreatitis in a previously healthy 32-month-old girl. In our case, secondary obstructive jaundice aggravated the pancreatic inflammation and was successfully treated with percutaneous transhepatic biliary drainage (PTBD).

Cystic and solid lesions of the pancreas

More than 95% of malignant tumours of the pancreas are exocrine carcinomas. The exocrine carcinomas have to be distinguished from benign serous cystadenomas and tumours, the latter including mucinous cystic neoplasms, serous cysts, and solid pseudopapillary neoplasms. Cystic lesions have to be separated from pseudocysts, which are the most common cysts. Pseudocysts are due to extensive confluent autodigestive tissue necrosis caused by alcoholic, biliary, or traumatic acute pancreatitis. This review focuses on the classification of the different types of solid and cystic lesions based on histological criteria. The various imaging procedures are also discussed, along with their strengths and limitations.

Non-Surgical Management of a Ruptured Posttraumatic Pancreatic Pseudocyst in a Child

Generally speaking, isolated pancreatic injuries are rare after abdominal blunt trauma. However, the incidence of pancreatic injuries in children has risen in recent decades. Pancreatic pseudocyst represents a typical complication after acute pancreatitis due to blunt abdominal trauma. Spontaneous rupture of pseudocysts leading to acute abdominal pain has been described, however, it rarely occurs, especially in pediatric patients. We report the successful non-surgical management of a ruptured pancreatic pseudocyst in a 5-year-old girl which occurred 27 days after trauma. The traumatic acute pancreatitis was due to a handlebar injury.

Rectal stenosis caused by foreign body reaction to sodium polystyrene sulfonate crystals (Kayexalate)

Sodium polystyrene sulfonate (SPS) (Kayexalate) is a cation-exchange resin used to treat hyperkaliema. Administered with sorbitol, it usually has minor adverse effects, but it may cause colonic or intestinal necrosis in uremic patients. We report an unusual case of rectal stenosis due to SPS crystals in a 46-year-old man. The patient had been involved in a car accident with severe thoracic and abdominal trauma. During his hospitalization, he presented traumatic acute pancreatitis with ischemic colitis because of hypotension, and acute renal insufficiency treated by hemofiltration and Kayexalate administered by nasogastric tube without sorbitol. Left colon was resected and Hartmann's procedure was performed. Restoration of the colon continuity was performed 13 months later. The rectal lumen was narrowed with a thickened rectal wall. Microscopic examination revealed fibrosis of the submucosa containing numerous basophilic polygonal crystals surrounded by macrophages. This is the first case report of rectal stenosis caused by foreign body reaction to SPS crystals after ischemic colitis.

Traumatic acute pancreatitis as a cause of large bowel obstruction.

Acute pancreatitis occurring as a result of trauma, either from a penetrating wound or a subcutaneous injury is sufficiently well known to merit discussion in text books. On the other hand intestinal obstruction developing as a direct result of pancreatitis is excessively rare, if one excludes those cases of paralytic ileus secondary to a severe suppurative pancreatitis of which the outcome is almost always fatal. Miln and Barclay (1952) described two cases of colonic obstruction sited at the splenic flexure treated initially by caecostomy. Further laparotomies at later dates revealed that acute pancreatitis had been the initiating cause. These authors found three other similar cases in the literature.
