Abstract
Background Hyperinsulinemic hypoglycemia is the most common cause of severe and persistent hypoglycemia in neonates and children. It is a heterogeneous condition with dysregulated insulin secretion, which persists in the presence of low blood glucose levels. Case presentation We report a case of a 15 year-old male with hyperinsulinemic hypoglycemia, who underwent a subtotal pancreatectomy after inadequate response to medical therapy. Pathological examination was positive for nesidioblastosis (diffuse β-cell hyperplasia by H-E and immunohistochemical techniques). The patient’s blood glucose levels normalized after surgery and he remains asymptomatic after 1 year of follow-up. The systematic review allowed us to identify 41 adolescents from a total of 205 cases reported in 22 manuscripts, from a total of 454 found in the original search done in PubMed and Lilacs. Conclusions Although very well reported in children, hyperinsulinemic hypoglycemia can occur in adolescents or young adults, as it happens in our reported case. These patients can be seen, treated and reported by pediatricians or adult teams either way due to the wide age range used to define adolescence. Most of them do not respond to medical treatment, and subtotal distal pancreatectomy has become the elected procedure with excellent long-term response in the vast majority.

Abstract
Management of congenital hyperinsulinemia of infancy (CHI) is challenging. A 4-month-old female infant with persistent hypoglycemia and elevated insulin levels was diagnosed with CHI. Gallium-68 DOTANOC positron emission tomography/computed tomography (PET/CT) scan (68Ga-labeled [1,4,7,10-tetraazacyclododecane-N,N',N'',N'''-tetraacetic acid]-1-NaI3-octreotide) demonstrated focal disease in the body of the pancreas. Genetic studies indicated paternal inheritance, making focal disease likely. She was started on diazoxide therapy with partial improvement in blood glucose levels. Due to a suboptimal response to diazoxide and the likelihood of focal disease amenable to surgery, a laparoscopic subtotal pancreatectomy with preservation of the head of the pancreas was performed. The biopsy demonstrated diffuse hyperplastic pancreatic islet cells on immunohistochemistry, indicative of diffuse rather than focal disease. Paternal inheritance is a recognized indicator of focal disease. Gallium-68 DOTANOC PET/CT scan is the only available imaging modality in South India as 18F-L-dihydroxyphenylalanine (DOPA) PET/CT scan is not available at present. A laparoscopic approach reduces the postoperative recovery time and morbidity in such patients. The absence of 18F-L-DOPA PET/CT scan and the limited supply of diazoxide makes the management of this complex condition more challenging in developing countries.

Abstract
PURPOSE Indications for total pancreatectomy (TP) have increased, including for diffuse main duct intrapapillary mucinous neoplasms of the pancreas and malignancy; therefore, the need persists for surgeons to develop appropriate endocrine post-operative management strategies. The brittle diabetes after TP differs from type 1/2 diabetes in that patients have absolute deficiency of insulin and functional glucagon. This makes glucose management challenging, complicates recovery, and predisposes to hospital readmissions. This article aims to define the disease, describe the cause for its occurrence, review the anatomy of the endocrine pancreas, and explain how this condition differs from diabetes mellitus in the setting of post-operative management. The morbidity and mortality of post-TP endocrine insufficiency and practical treatment strategies are systematically reviewed from the literature. Finally, an evidence-based treatment algorithm is created for the practicing pancreatic surgeon and their care team of endocrinologists to aid in managing these complex patients. METHODS A PubMed, Science Citation Index/Social sciences Citation Index, and Cochrane Evidence-Based Medicine database search was undertaken along with extensive backward search of the references of published articles to identify studies evaluating endocrine morbidity and treatment after TP and to establish an evidence-based treatment strategy. RESULTS Indications for TP and the etiology of pancreatogenic diabetes are reviewed. After TP, ~80% patients develop hypoglycemic episodes and 40% experience severe hypoglycemia, resulting in 0-8% mortality and 25-45% morbidity. Referral to a nutritionist and endocrinologist for patient education before surgery followed by surgical reevaluation to determine if the patient has the appropriate understanding, support, and resources preoperatively has significantly reduced morbidity and mortality. The use of modern recombinant long-acting insulin analogues, continuous subcutaneous insulin infusion, and glucagon rescue therapy has greatly improved management in the modern era and constitute the current standard of care. A simple immediate post-operative algorithm was constructed. CONCLUSION Successful perioperative surgical management of total pancreatectomy and resulting pancreatogenic diabetes is critical to achieve acceptable post-operative outcomes, and we review the pertinent literature and provide a simple, evidence-based algorithm for immediate post-resection glycemic control.

Abstract
Persistent hyperinsulinemic hypoglycemia of infancy (PHHI) is relatively rare but one of the most important causes of severe neonatal hypoglycemia. Recognition of this entity becomes important due to the fact that the hypoglycemia is so severe and frequent that it may lead to severe neurological damage in the infant manifesting as mental or psychomotor retardation or even a life-threatening event if not recognized and treated effectively in time. Near-total pancreatectomy may be required for patients with intractable hypoglycemia despite medical treatment; however, that may result in diabetes mellitus or recurrent postoperative hypoglycemia. This review aims to consolidate the traditional concepts and current information related to the pathogenesis and management of PHHI.

Abstract
Near-total pancreatectomy has been recommended as the treatment for persistent hyperinsulinemic hypoglycemia (PHH) in infants. However, recently there has been a report described that one third of 95% pancreatectomy failed to prevent hypoglycemia and more than two thirds had diabetes ultimately. The authors experienced 2 cases of PHH, which raise a query about the extensive pancreatectomy. Case 1: A female patient who manifested PHH shortly after birth underwent less extensive pancreatectomy twice at age 2 months and 8 years. After each operation, her clinical symptoms regressed, and she became free from the disease eventually. Histologic findings showed nesidioblastosis in which the islets clearly matured. Case 2: A male infant with PHH had an absolute indication for pancreatectomy. However, after a meticulous control of the blood glucose level with parenteral nutrition followed by continuous enteral nutrition feeding combined with medication, he became free from the disease. The current cases show there exist cases of PHH in which the islets mature and symptoms regress spontaneously. Therefore, we conclude near-total pancreatectomy is not always the treatment of choice. As an alternate strategy, long-term controlled feeding and medication combined with or without less extensive pancreatectomy should be considered with the expectation of spontaneous regression.

Abstract
BACKGROUND/PURPOSE Congenital hyperinsulinism induces severe and unremitting hypoglycemia in newborns and infants. If poorly controlled, seizures and irreversible brain damage may result. Subtotal (<95%) or near-total (95% to 98%) pancreatectomy have been performed for glycemic control in babies who do not respond to aggressive medical therapy. Because hypoglycemia often persists after subtotal resection, 95% pancreatectomy has emerged as the procedure of choice. To define the effect of more or less extensive pancreatectomy on the management and outcome of refractory congenital hyperinsulinism, the authors examined our single institutional experience. METHODS The records of children treated between 1963 and 1998 for congenital hyperinsulinism, and who required pancreatectomy, were reviewed. Outcome parameters included glycemic response to surgery, need for reresection, surgical morbidity, surgical and long-term mortality, and development of diabetes mellitus (DM). A complete response was defined as discharge to home on no glycemic medications, no continuous feedings, and without DM. Histological reports were reviewed and categorized as either diffuse or focal disease. RESULTS Of 101 children treated for congenital hyperinsulinism during this period, 53 (50%) required pancreatectomy for glucose control. Mean follow-up for the study population was 9.8 +/- 1.1 years. Overall, 23 children (43%) showed a complete response, occurring in 50% of patients having > or = 95% pancreatectomy (n = 34), but in only 19% having less than 95% resection (n = 16). The remaining three babies had local excision of a solitary focal lesion, and each showed a complete response. Histopathology showed diffuse islet abnormalities in 42 specimens (79%) and solitary focal lesions in 11 (21%). A complete response was observed for 82% of focal but only 33% of diffuse lesions. Eight patients (15%) required reresection for persistent hypoglycemia, seven having diffuse lesions and one focal. Surgical morbidity occurred in 13 cases (26%), and the 30-day surgical mortality rate was 6%, each death (n = 3) occurring before 1975. DM developed in seven children (14%), each having diffuse lesions, and was independent of resection type. CONCLUSION Because euglycemia is more readily restored, and because the risks for surgical complications and DM do not appear increased, the authors recommend 95% pancreatectomy as the initial procedure of choice for newborns and infants with congenital hyperinsulinism.

Abstract
AIM To evaluate long term detailed pancreatic endocrine and exocrine function in children with persistent hyperinsulinaemic hypoglycaemia of infancy (PHHI) after 85-95% pancreatectomy. METHODS Six children with PHHI between 0.9 and 12.7 years after pancreatic resection underwent clinical and investigative follow up at 1.0 to 14.9 years of age. One child with PHHI who had not had pancreatectomy was also assessed. Standard endocrine assessment, pancreatic magnetic resonance imaging (MRI), and detailed direct and indirect tests of exocrine pancreatic function were performed. RESULTS Pancreozymin-secretin stimulation test results were normal in only one child, borderline in two, and deficient in four, one of whom requires daily pancreatic enzyme supplements. Pancreolauryl tests performed in three children were borderline in two and abnormal in the other. Only one child had low faecal chymotrypsin values. One child developed insulin dependent diabetes at 9 years and two children at 1.0 and 13.3 years require diazoxide to maintain normoglycaemia. MRI showed no major regrowth of the pancreatic remnant after resection (n = 5). CONCLUSIONS Clinical evidence of endocrine or exocrine dysfunction has developed in only two patients to date, but detailed pancreatic function testing suggests subclinical deficiency in all but one of our patients with PHHI. Although 95% pancreatectomy results in postoperative control of blood glucose, subclinical pancreatic insufficiency is present on long term follow up and development of diabetes mellitus and exocrine failure remain ongoing risks.

Abstract
The two major forms of infantile persistent hyperinsulinemic hypoglycemia require different treatments, but are difficult to differentiate during surgery. Indeed, one is characterized by focal adenomatous hyperplasia often macroscopically invisible, whereas the other consists of a diffuse, but discreet, beta-cell abnormality. We evaluated, in a large series of persistent hyperinsulinemic hypoglycemia, the reliability of two criteria in differentiating these two forms: the mean beta-cell nuclear radius (MNR) and the beta-cell nuclear crowding, i.e. the number of nuclei per 1000 micron 2 beta-cell (BCNC). The values of the largest MNR and of BCNC in cases bearing a focal lesion (respectively, 3.27 microns +/- 0.25 and 14.62 +/- 1.78) were significantly different from those in the diffuse pathology (4.25 microns +/- 0.43 and 10.00 +/- 1.55). Setting the threshold value of MNR at 3.70 microns and that of BCNC at 12.00 enabled correct classification of 90.9% of the diffuse and 100% of the focal forms. beta-Cell nuclear analysis can thus contribute to a subclassification of the syndrome, not allowed by clinical or biological data. If performed during surgery it could help in determining the extent of pancreatectomy necessary to cure the patient, as the diffuse form, with abnormal nuclei in the whole pancreas, requires subtotal to near-total pancreatectomy, whereas the focal form, devoid of abnormal insular beta-cell nuclei, can be cured by partial pancreatectomy.

Abstract
We herein present two female siblings with persistent hyperinsulinemic hypoglycemia in the neonatal period who were diagnosed as having familial nesidioblastosis. Despite both the administration of diazoxide and the intravenous infusion of glucose, one of the affected infants died of severe metabolic acidosis at about 1 month of age, before pancreatectomy could be performed. The other, in whom the disorder was diagnosed early, also failed to respond to conservative medical treatment and ultimately required a 99% pancreatectomy for control of hypoglycemia. A third female sibling was normal. The possibility of familial nesidioblastosis should thus be considered in the case of neonatal intractable hypoglycemia to ensure a prompt diagnosis and allow for early surgical intervention when indicated. The relevant literature on this life-threatening disorder is also reviewed.

Abstract
Eight patients with persistent hyperinsulinemic hypoglycemia of infancy who were treated with octreotide without pancreatectomy are described. All had severe, early-onset disease that would have required partial pancreatectomy had octreotide not been available. Along with octreotide, frequent feedings and raw cornstarch at night were required by all. Octreotide was given in three or four daily subcutaneous injections in four patients and in a continuous subcutaneous infusion with an insulin infusion pump in four. All had mild, transient gastrointestinal symptoms (vomiting, abdominal distention, steatorrhea) after the start of therapy. Asymptomatic gallstones were found in 1 patient after 1 year of treatment. No other long-term untoward effects were noted, including no detrimental effect on psychomotor development. Growth was not affected in five of six patients treated for more than 6 months. In five patients, octreotide was discontinued after 9 months to 5 1/2 years; patients were given diazoxide instead, two required percutaneous gastrostomy, and one 5 1/2-year-old child required no further treatment. The remaining three patients (aged 5 to 9 months) are still being treated with octreotide. We conclude that, with the use of octreotide, pancreatectomy can be avoided in some patients. Particularly in light of our findings of a high incidence of diabetes years after partial pancreatectomy, and clinical improvement after months to years of octreotide treatment, we believe that aggressive medical therapy, when effective, is preferable to partial pancreatectomy.

Abstract
The literature is riddled with misconceptions concerning the landmarks and the actual amount of pancreatic tissue resected in "subtotal" 60% to 90% pancreatectomies. In order to clarify the surgical anatomy of the pancreas, 13 autopsy specimens from children aged 2 days to 15 years were carefully examined. Pancreata were serially removed from the in situ position in four sections and weighed. Section 1 included pancreatic tissue from the tail to the left of the superior mesenteric vessels (SMV); section 2 included all tissue from the tail to the right of the SMV; section 3 contained tissue up to the left of the pancreaticoduodenal vessels in the head of the pancreas; and section 4 included the remainder of the pancreatic head within the duodenal sweep and the uncinate process. Results showed that section 1 weighed 47.5% +/- 9.7% (mean +/- SD) of the total pancreatic weight with a wide range of 32.3% to 67.3%; section 2 weighed 53.5% +/- 9.0% (range, 38.7% to 72.2%); section 3 weighed 69.1% +/- 15.6% (range, 43.5% to 95.8%); and section 4 weighed 31.6% +/- 14.6% (range, 4.2% to 56.5%). As noted, pancreatic anatomy was extremely variable in relation to the percent of tissue to either side of the SMV and the proportion of tissue contained within the uncinate process. Resections historically reported to result in a "75%" pancreatectomy (section 2) were demonstrated to contain a mean of only 53.5% +/- 9.0% of the pancreas. Less tissue than expected would be resected by using the SMV as landmarks for a 75% resection. The wide variation in anatomy also has important clinical implications in performing "subtotal" pancreatectomies in infants with nesidioblastosis in whom the amount of tissue resected is critical to the patient's postoperative clinical course. This study demonstrates that a subtotal pancreatectomy should not be based upon the presumed relation of the pancreatic substance to the SMV. The entire gland including the uncinate process should be visualized at operation in order that a proper pancreatectomy is performed.

Abstract
Despite a greater awareness of hyperinsulinaemic hypoglycaemia, one in three patients has some degree of mental retardation by the time the diagnosis is made. The diagnosis is established by demonstrating high plasma insulin concentrations during an episode of hypoglycaemia. Twenty one hyperinsulinaemic infants and children were referred for surgical treatment after failing to respond to medical management. The surgical procedure of choice is a 95% pancreatectomy. Recurrence of the hypoglycaemia may develop after less radical resections as occurred in one patient who then underwent an extended resection 72 hours postoperatively. Patients who fail to respond to optimal medical treatment should be referred for surgery early and not as a last resort if permanent neurological damage is to be avoided.

Abstract
A review of the literature on the surgical treatment of nesidioblastosis in childhood was made to answer the following questions: age at operation, surgical procedure, pathohistological findings, incidence of recurrence and its treatment, as well as mortality. Primary subtotal pancreatectomy appears to be the method of choice. It should be performed as early as possible following exact diagnosis. Total pancreatectomy is reserved for treatment of a recurrence.

Abstract
A series of 18 children suffering from persistent idiopathic neonatal hypoglycemia (PINH) is reported. Medical and surgical managements are described in detail. All patients subjected to surgery had failed medical treatment. These patients were divided into two groups: 1) 85% pancreatectomy leaving the uncinate process in situ, and 2) 95% pancreatectomy leaving a small rim of pancreatic tissue along the duodenum and the common bile duct. The spleen was preserved in all cases. Two out of 5 children of group 1 required further resection of the pancreas for persistent hypoglycemia and were converted to 95% pancreatectomy. Since 1981 95% pancreatectomy was exclusively employed. Only one patient required insulin for 3 weeks postoperatively. Histopathology and immunohistochemistry revealed islet cell dysplasia and islet cell nuclear hypertrophy in the majority of cases, 35% of the patients had focal adenomatosis. Better control of hypoglycemia is achieved by primary 95% pancreatectomy and, thus, 95% pancreatectomy is recommended as the initial procedure in the treatment of PINH.

Abstract
Pancreatic disorders in infants and children encountered over a 20 year period are reviewed. A total of 79 children were treated. Forty-eight had pancreatitis or its complications, 17 had congenital malformations, 12 had hypoglycemia and hyperinsulinism, and 2 had carcinoma. The mortality rate for the children with pancreatitis was 17 percent and was limited to patients treated nonoperatively. Idiopathic and drug-induced pancreatitis (the latter, particularly from corticosteroids) were the predominant types. Only rarely should such patients undergo operative treatment. Operations performed for various obstructive or traumatic lesions of the pancreas, as well as for complications of pancreatitis, obtained uniformly good results. The most common congenital malformation of the pancreas was an annular pancreas in association with duodenal atresia; all children with this abnormality were successfully treated with bypass procedures. Four patients with an ectopic pancreas underwent successful wedge resection. Nine infants with nesidioblastosis or islet cell hyperplasia and three children with islet cell adenomas underwent successful resection without any deaths, although neurologic sequelae due to prolonged preoperative hypoglycemia were common. Two patients underwent radical resection for pancreatic carcinoma, one of whom had survived 20 years postoperatively at last follow-up. Pancreatic disorders requiring operation in childhood are uncommon, but are likely to be complex and challenging when they do occur.

Abstract
Neonatal hypoglycemia caused by islet cell dysplasia (ICD), sometimes called nesidioblastosis, may lead to psychomotor retardation and neurologic dysfunction in up to 50% of patients who are not given early aggressive treatment. In 1979, we adopted a more aggressive protocol for treating this condition that consists of the following steps: immediate insertion of a silastic central venous line for reliable venous access; continuous intravenous infusion of glucose and glucagon to maintain euglycemia; oral diazoxide; and near total pancreatectomy if the first steps fail to overcome the hypoglycemia or the patient cannot be weaned off intravenous therapy. Twelve consecutive patients who underwent pancreatectomy for control of hypoglycemia between 1979 and 1984 were recalled and evaluated for growth delay, neurologic dysfunction, and psychomotor retardation using the Revised Yale Developmental Schedules, the Peabody Picture Vocabulary, and the Draw a Man Test. Follow-up ages ranged from 1.2 to 6.0 years with a median of 3.6 years. No significant growth abnormalities were identified. No patient exhibited focal neurologic dysfunction, although some demonstrated soft neurologic signs, which did not appear to be related to their earlier hypoglycemia. Psychomotor function for the group as a whole was normal, with a mean developmental quotient (DQ) of 99.2. The DQ was average for five patients and above average for four; no patient had a DQ in the frankly subnormal range. Psychomotor development correlated better with the family's socioeconomic and educational status than with the neonatal hypoglycemia. These children are developmentally and neurologically normal despite severe neonatal hypoglycemia. Continued follow-up will be necessary to detect any late sequelae.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Persistent hyperinsulinism in the newborn may warrant surgical intervention to prevent neurologic sequelae. Subtotal pancreatectomy may not be adequate, necessitating near-total pancreatectomy with subsequent development of diabetes mellitus. We report an infant with hyperinsulinemic hypoglycemia who underwent near-total pancreatectomy. The postoperative period was characterized by insulin-dependency and extreme insulin sensitivity. Clinical follow-up and C-peptide determinations showed a return of insulin secretory capacity permitting the discontinuation of insulin therapy after five months. This experience reaffirms the potential for a favorable outcome after near-total pancreatectomy in the newborn period for severe hyperinsulinism.

Abstract
Conventional 85% pancreatectomy with splenectomy performed for management of hypoglycemia of neonatal nesidioblastosis has been followed by a dismal prognosis characterized by post-splenectomy sepsis, recurrent hypoglycemia, permanent brain damage, and a high mortality. For our last eight infants we have found it possible to remove at least 95% of the pancreas, preserving the blood supply to the spleen as well as the duodenum. This has permitted satisfactory control of the hypoglycemia and long-term septic complications have been avoided. Follow-up evaluation up to 20 years with successful control of hypoglycemia without progressive brain damage indicates the value of this primary extensive surgical approach.

Abstract
Pancreatic tissue obtained at subtotal pancreatectomy from 15 infants with persistent hypoglycaemia with hyperinsulinism, and autopsy specimens from 23 age-matched normoglycaemic controls, were studied with morphometric methods after immunocytochemical staining of the four main islet cell types (A, B, D and pancreatic polypeptide cells). In three cases, a focal lesion was detected by gross examination. Macroscopic or microscopic examination did not distinguish the 12 other cases from controls. As found previously, nesidioblastosis was not a specific feature of the pancreas in infantile hypoglycaemia, being observed in age-matched controls as well. In cases with hypoglycaemia the volume density of B cells was not significantly increased; that of the A cells was within normal range. The volume density of pancreatic polypeptide cells was markedly augmented and that of somatostatin cells was significantly decreased. The mean nuclear volume of the B cells was increased by 40% in cases with diffuse changes, but in cases with a focal lesion this increase was restricted to the abnormal area. This finding is of decisive importance for diagnosis and has therapeutic implications. The increase in B-cell nuclear size is thought to reflect an enhanced functional activity of these cells. On the other hand, the figures obtained for the volume density of B and D cells must be viewed with some reservation because degranulation may interfere with accurate detection of these cells.
