Abstract
INTRODUCTION Pancreas divisum (PD) is a common congenital anomaly of the pancreas, but its genetic basis remains unknown. The purpose of this genome-wide association study was to identify genetic loci associated with PD. METHODS Using the Mass General Brigham Biobank, patients diagnosed with PD were identified. Quality control and imputation were performed using standard approaches. Single nucleotide polymorphisms (SNPs) with minor allele frequency (MAF) ≥ 5% were tested for association with PD using mixed linear model-based association analysis. The significance threshold was set at 5 × 10-8. RESULTS A total of 13,940 subjects were included, of which 251 (1.8%) were diagnosed with PD. A genetic locus in chromosome 3q29 was found to be associated with PD (lead SNP rs3850646, MAFPD = 34.6% vs. MAFcontrols = 26.4%, beta = 0.0106, P = 1.47 × 10-8). The identified locus is located in the phosphatidylinositol glycan anchor biosynthesis class Xand p21 activated kinase 2genes. The heritability of PD was estimated at 27.5%. (Expression quantitative trait loci) and chromatin interaction analysis found 12 genes whose expression may be regulated by SNPs in this genomic locus. CONCLUSIONS The results of this study suggest that a genetic locus at 3q29 is associated with PD. This locus is in the phosphatidylinositol glycan anchor biosynthesis class X and p21 activated kinase 2 genes. Twelve candidate genes were identified whose expression may be regulated by this locus. These findings may help us understand both normal and aberrant pancreatic development and may aid in clinical evaluation and genetic counseling of patients with PD and associated diseases, such as acute pancreatitis.

Abstract
Many pancreatic disorders in children benefit from a multidisciplinary approach. This is especially true for acute and chronic pancreatitis which has numerous and diverse etiologies. The current management of pancreatitis is reviewed, focusing on recent advances. Children with pancreatitis must be fully investigated, not least to select out those who benefit from specific surgical interventions. The treatment of pancreas divisum, pseudocysts, and fibrosing pancreatitis deserve particular consideration. Management of pancreatic injuries involving the main pancreatic duct is both variable and controversial. Treatment should be individualized depending on the site of injury, timing of referral, presence of associated injuries, and institutional expertise.

Abstract
Pancreatitis is under appreciated during childhood although its diagnosis is simple and management straightforward in most cases. There is a range of possible causes, which is quite different to the situation in adults. The commonest underlying problems are probably structural abnormalities of the pancreatic and biliary ducts such as choledochal malformation, common pancreatobiliary channel and pancreas divisum. Other causes, which can be important in certain groups and geographical areas, are those due to drug reactions, viral infection and parasitic infestation, and blunt abdominal trauma. The diagnosis is established by showing a significantly raised plasma amylase level. Other diagnostic tools such as ultrasound, computed tomography (CT) scanning and endoscopic retrograde cholangiopancreatography (ERCP) have a major role in determining possible underlying causes, and hence selecting out those who require definitive corrective surgery. The pathophysiology of pancreatitis remains to be fully elucidated and, in the acute phase can affect other organs such as the renal and respiratory systems. Later complications include sepsis, pancreatic abscess and typically pseudocyst formation. Most of these can be treated using minimally invasive techniques such as percutaneous aspiration although open surgical techniques such as cystgastrostomy may be required in a few.

Abstract
OBJECTIVE To analyze an institutional experience with pancreatitis in childhood to clarify the frequency of pancreas divisum in that patient population, the characteristics of pancreatitis in children with pancreas divisum, and the role of surgical management in their treatment. SUMMARY BACKGROUND DATA The role of pancreas divisum in causing acute and relapsing pancreatitis and chronic, recurring abdominal pain is controversial. Although the anatomical abnormality is present from birth, most investigators have reported cases with onset of symptoms in adulthood. The reported pediatric experience with this disorder is small, and the natural history of pancreatitis in children with pancreas divisum has not been well elucidated. METHODS A retrospective chart review of all children 18 years of age and younger with a discharge diagnosis of pancreatitis identified 135 patients treated in the authors' institution from 1978 to 1998. Ten patients were found to have anatomical variants of pancreas divisum associated with recurrent or chronic pancreatitis. The medical records of these patients were reviewed for data on the presentation, diagnostic findings, imaging studies, treatment, surgical findings, and pathologic findings in these children. Chart review and telephone calls were used to assess the current state of health in nine patients available for follow-up. RESULTS Pancreas divisum was identified in 7.4% of all children with pancreatitis and 19.2% of children with relapsing or chronic pancreatitis. Patients had early onset of recurrent episodic epigastric pain and vomiting, at a mean age of 6 years. Three patients had a positive family history of pancreatitis and one was proven by DNA analysis to have hereditary pancreatitis. Pancreatitis was documented by elevated amylase or lipase levels, and endoscopic retrograde cholangiopancreatography was the method of diagnosis of pancreas divisum in all patients. Eight patients had complete pancreas divisum and two had incomplete variants. Eight patients underwent surgery to improve ductal drainage. Seven underwent transduodenal sphincteroplasty of the accessory papilla, along with sphincteroplasty of the major papilla in two (plus septoplasty in one). Three patients underwent longitudinal pancreaticojejunostomy, as a primary procedure in one patient with midductal stenosis and in two because of recurring pancreatitis after sphincteroplasty. The surgical findings and histologic examination of five patients undergoing distal pancreatectomy revealed striking changes of advanced chronic pancreatitis. Patients responding to sphincteroplasty alone showed less severe histologic changes. Overall, three of seven patients had excellent results, three were improved, and one had continued disabling attacks of pancreatitis. The mean duration of follow-up was 7.3 years, and there were no deaths. No patients had endocrine or exocrine pancreatic insufficiency, and none required chronic analgesics. CONCLUSIONS Pancreas divisum is an important cause of recurrent pancreatitis in childhood and should be sought aggressively in children with more than one episode of pancreatitis or pancreatitis with a history of chronic recurrent abdominal pain. Surgical intervention is directed toward relief of ductal obstruction and may involve accessory duct sphincteroplasty alone or in combination with major sphincteroplasty and septoplasty. Patients with more distal ductal obstruction or ductal ectasia may benefit from pancreaticojejunostomy.

Abstract
Pancreas divisum is the most common congenital anomaly of the pancreas. Its relationship to the development of pancreatitis is controversial. The authors report on an 8-year-old girl who presented with recurrent bouts of acute pancreatitis and multiple failed attempts at endoscopic retrograde cholangiopancreatography (ERCP) who was referred for surgical exploration. She was found to have marked stenoses of both major and minor papillae and an intraoperative pancreaticogram consistent with pancreas divisum. She underwent sphincteroplasty of both major and minor papillae and remains symptom-free after 22 months. It is believed that in a patient with pancreatitis and pancreas divisum, or in a patient with pancreatitis and multiple failed attempts at ERCP, transduodenal exploration and intraoperative pancreaticogram are appropriate next steps in management. If pancreas divisum in association with minor papilla stenosis is found, sphincteroplasty is appropriate therapy. If major papilla stenosis is also present, we recommend sphincteroplasty of both the major and minor papillae.

Abstract
A multidisciplinary approach using traditional open surgery, endoscopic retrograde cholangiopancreatography (ERCP) and laparoscopic surgery has revolutionized the care of the adult with pancreaticobiliary disease. This study focuses on a similar collaborative effort to diagnose and treat children with pancreaticobiliary disorders. Charts of all patients treated on the pediatric surgery service between June 1990 and May 1995, who also underwent ERCP, were abstracted for disease process, presenting symptoms, laboratory evaluation, surgical or endoscopic procedures, and eventual outcome. Twenty-six children were identified, ranging from 6 months to 19 years of age. Pancreaticobiliary disorders included pancreas divisum (n = 1), choledochal cyst (n = 4), pancreaticobiliary trauma (n = 4), cholelithiasis and choledocholithiasis (n = 17). The pancreaticobiliary tree was successfully visualized by ERCP in 25 of 26 (96%) patients. Fifteen of these patients also underwent attempted therapeutic endoscopic procedures, with 13 (87%) performed successfully. Three patients with choledochal cyst had stents placed preoperatively for cholangitis, all of whom have undergone successful choledochal cyst excision. Two trauma patients underwent attempted stenting of a bile leak and bile duct stricture, respectively, both of which were unsuccessful, necessitating surgical correction. Seventeen patients with cholelithiasis underwent ERCP to rule out choledocholithiasis. Ten patients were found to have common duct stones, and all stones were endoscopically extracted, including those in a 6-month-old child. Overall survival rate was 96% (25 of 26), with the one death occurring in a trauma patient unrelated to his pancreaticobiliary disorder. A multidisciplinary approach using traditional open surgery, ERCP and laparoscopic surgery can successfully treat even young children with pancreaticobiliary disorders. In experienced hands, diagnostic ERCP and therapeutic endoscopic intervention can be performed successfully in most pediatric patients, greatly simplifying the surgical management of these potentially complex problems.

Abstract
Acute pancreatitis in children is a little known and poorly defined disease, and thus rarely considered in the diagnosis of pediatric abdominal pain. In the past 14 years, the authors treated 21 children who had acute pancreatitis. Trauma was the cause of the disease in 29% of the patients. One third (33%) had hypovolemic shock-related pancreatitis (mostly after either cardiopulmonary bypass or severe gastrointestinal bleeding). Furthermore, a major proportion (38%) had severe underlying organic disease. The clinical presentation was unremarkable; most patients (83%) had abdominal pain, especially in the epigastrium, and vomiting was the only other clinical sign exhibited by more than 50%. The Glasgow score (a severity grading system based on eight laboratory values and calculated within the first 48 hours after admission) had good specificity but poor sensitivity. Amylasemia had no predictive value. More than half our patients (57%) had complications, mainly pseudocysts (24%) and relapse (14%), and about one quarter (24%) had severe pancreatitis. There were two deaths (10%), and all surviving children (90%) eventually were symptom-free. Treatment was conservative in the majority of cases; eight patients (38%) required surgery. Hypovolemic shock and a severe underlying pathology were identified as risk factors for the occurrence of severe pancreatitis (P < .005) or death (P < .001), but not for the development of complications.

Abstract
Hereditary pancreatitis is characterized by an autosomal-dominant mode of inheritance with incomplete penetrance, onset of symptoms in childhood or early adolescence (mean age of onset approximately 13 years), and an approximately equal sex incidence. Pancreas divisum is a congenital variant of pancreatic ductal anatomy in which the ventral and dorsal pancreatic ductal systems fail to fuse, so that two functional papillae drain the exocrine secretions of the pancreas. In recent years, several reports of pancreatitis associated with pancreas divisum in children have appeared. We now report a family in which the mother, son, and daughter all had presented with recurrent pancreatitis from an early age. Both the mother and son have endoscopic retrograde cholangiopancreatography-documented pancreas divisum, whereas the daughter has a stricture in her distal pancreatic duct. To our knowledge, this is the first such report of "familial" pancreas divisum. The implications of these findings in the setting of hereditary pancreatitis highlight the controversial issues of the clinical significance of pancreas divisum and the appropriateness of surgical therapy.

Abstract
Fifty-one children with anatomical anomalies of the pancreatic duct developed pancreatitis associated with either congenital dilatation of the bile duct (choledochal cyst; n = 48) or other rare causes (n = 3). Among those with choledochal cyst, 41 underwent primary surgical resection of the dilated bile duct, while five of the remaining seven patients receiving cystenterostomy underwent secondary resection of the cyst.

Abstract
Pancreas divisum results in drainage of most pancreatic secretions through the minor papilla via the dorsal duct, and the association of minor papilla stenosis has been implicated as a cause of pancreatitis. Most of the reported cases represent pancreatitis confined to the dorsal part. The authors treated a 10-year-old boy with recurrent pancreatitis that was substantially more severe in the ventral part. The patient was referred with a brief history of abdominal pain and had undergone a laparotomy when segmental ventral pancreatitis had been observed. Severe pancreatitis and acute renal failure developed, which required drainage of the lesser sac and hemodialysis, respectively. After 5 months, he had another episode that subsequently led to a pseudocyst in the ventral part. Endoscopic retrograde cholangiopancreatography via minor papilla showed a normal-caliber dorsal duct communicating with a part of the fine ventral ducts. A normal biliary tree was shown, but no ventral duct was visualized by cannulation to the major papilla of Vater. Dual sphincteroplasties and a cholecystectomy were performed. The minor papilla was stenotic and admitted only the finest lacrimal duct probe. The orifice of the ventral duct could not be observed. Thus it was clarified that the dorsal duct with its stenotic orifice had drained both the dorsal and ventral pancreas. The patient has remained asymptomatic over 36 months postoperatively. Despite their limited experience, the authors believe that (1) this anatomic variant led to ventral pancreatitis, and (2) the sphincteroplasty of the minor papilla was successful.
