The incidence of acute pancreatitis (AP) has increased in the pediatric population over the past few decades and it stands to follow that the complications of severe AP, including symptomatic pancreatic fluid collections (PFCs) will increase as well. In adults, the therapeutic options for this situation have undergone a dramatic evolution from mainly surgical approaches to less invasive endoscopic approaches, mainly endoscopic ultrasound-guided transmural drainage (EUS-TD) followed be direct endoscopic necrosectomy if needed. This has proven safe and effective in adults; however, this approach has not been well studied or reported in pediatric populations. Here we demonstrate that EUS-TD seems to offer a safe, efficacious and minimally invasive approach to the management of large PFCs in pediatric patients by reviewing two representative cases at our institution.

A 55-year-old man was admitted to the hospital for jaundice. Computed tomography (CT) scans showed a diffuse mass in the pancreas and peripancreatic area, with infiltration to of the whole pancreas, and overall reduced enhancement compared to normal pancreas. Esophagogastroduodenoscopy revealed elevated mucosal lesion covered hyperemic mucosa at duodenal bulb and ulcerative lesion at body of stomach. Endoscopic ultrasonography revealed an irregular mass with unclear boundaries was observed within the pancreas. Abrupt narrowing of mid to distal common bile duct was seen and the stricture was caused by compression of pancreatic mass. Plastic stent was inserted and clinical improvement was achieved including resolution of jaundice. The patient is currently being treated with combination of rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone. We report a case of primary pancreatic lymphoma presenting with obstructive jaundice.

In acute pancreatitis group, all the dogs are showed increase of amylase and lipase after the 1st day of surgery, and amylase and lipase activity were significantly more increased than those of control group. The methemalbumin was increased significantly after the 2nd day of surgery in the acute pancreatitis group. In pancreatitis group, ultrasonographic findings included thickened duodenal wall and poorly circumscribed hyperechoic lesion of pancreatic mass after the 2nd day of surgery. And the lesion was exacerbated until the 4th day and reduced after the 6th day of surgery. To identify the lesion of pancreas, it is considered that transverse view is more useful Than sagittal view. Gross findings showed increase of pancreatic parenchymal consistency, surface nodule, and extensive pancreatic necrosis. Necrosis of peripancreatic fat tissue was also a prominent feature. The microscopic appearance of the pancreas was characterized by pancreatic acinar cell necrosis, hemorrhage, infiltration of the inflammatory cell and fat necrosis and saponification were also observed.

A six-year-old female cocker spaniel presented with recurring episodes of pelvic limb weakness and intermittent seizures. Laboratory analysis revealed marked hypoglycemia and an elevated serum insulin concentration. A pancreatic beta-cell tumor at stage III ($T_1N_1M_1$) was diagnosed based on serial blood glucose and insulin measurements along with diagnostic imaging. The patient survived for 140 days after diagnosis with medical management, including frequent feeding and prednisolone therapy. On necropsy, necrosis and masses in the peripancreatic omentum and liver were found; pancreatic beta-cell neoplasia with metastasis to the liver was confirmed by histopathologic examination. This case reports hyper-insulinism in a dog presenting with hypoglycemic seizures.

A 7-year-old, castrated, male Maltese dog presented with hyporexia and depression for 3 days. Elevated serum amylase, lipase activities, and liver enzyme values were found upon blood examination. An abdominal mass was seen on radiographs caudal to the gastric body in the left middle abdomen. In the left middle abdomen, abdominal ultrasonography also revealed a massive, irregularly marginated, heterogeneous mass of unknown origin, and in the right cranial abdomen, heterogeneously hypoechoic pancreatic tissue and hyperechoic change of adjacent mesenteric fat were observed. Contrast-enhanced computed tomography showed an irregular contour of the left pancreatic limb as well as heterogeneously enhanced parenchyma. A low-attenuating peripancreatic fluid collection with a thin and irregular wall was also seen. Based on these findings, an atypical pancreatic abscess with necrotizing pancreatitis which manifested as walled-off necrosis was suspected. The mass was excised, and the pancreatic abscess was confirmed by histopathologic examination. No complications were found in the patient after two months of follow-up examination.

Traumatic diaphragmatic injuries (TDIs) are a rare complication in thoraco-abdominal trauma. The diagnosis is difficult and if left untreated, TDI can cause traumatic diaphragmatic hernia (TDH). Through an injured diaphragm, the liver, spleen, stomach, small intestine, and large intestine can be herniated to the thoracic cavity, but pancreatic herniation and pancreatitis are quite rare in TDH. This paper reports a case of pancreatitis developed by additional trauma in a patient with asymptomatic chronic TDH. A 58-year-old male visited the emergency department with a left abdominal injury after a fall 6 hours earlier. The vital signs were stable, but the amylase and lipase levels were elevated to 558 U/L and 1,664 U/L, respectively. Abdominal computed tomography (CT) revealed a left diaphragmatic hernia and an incarceration of the stomach, pancreatic ductal dilatation, and peripancreatic fatty infiltration. Additional history taking showed that he had suffered a fall approximately 20 years ago and had an accidentally diaphragmatic hernia through a chest CT 6 months earlier. A comparison with the previous CT revealed the pancreatitis to be caused by secondary pancreatic ductal obstruction due to the incarcerated stomach. For pancreatitis, gastrointestinal decompression was performed, and after 3 days, the pancreatic enzyme was normalized; hence, a thoracotomy was performed. A small ruptured diaphragm was found and reposition of the organs was performed. This paper reports the experience of successfully treating pancreatitis and pancreatic hernia developed after trauma without complications through a thoracotomy following gastrointestinal decompression.

The state of intense peripancreatic inflammation in chronic pancreatitis can give rise to various vascular complications such as venous thrombosis and arterial pseudoaneurysms. Due to its intimate location with the pancreas, spleno-mesenteric-portal axis suffers the greatest blunt of thrombotic complications. Treatment modalities for such cases of chronic portal vein thrombosis have always been controversial and challenging. Medical management with anticoagulants is both risky and unsatisfactory due to presence of varices, hypersplenism, and persistence of the inflammatory pathology. Although endovascular techniques have been tried in various case reports, there are definite anatomical challenges in cases of long segment porto-mesenteric thrombosis with massive ascites. Surgical shunts have been historically described for cirrhotic and non-cirrhotic portal hypertensive patients. However, its use in patients with refractory ascites due to chronic pancreatitis induced portal vein thrombosis has not been reported in the medical literature. Here, we present a case of an extensive portal vein thrombosis with massive refractory ascites in a patient with alcohol-induced chronic pancreatitis successfully treated with a surgical mesocaval shunt using an interposition small diameter graft.
