Abstract
PURPOSE Hypertrophic pyloric stenosis (HPS) is the most common cause of gastric obstruction in newborns. Extra-mucosal pyloromyotomy can be performed through a small laparotomy or laparoscopy. The aim of this study was to compare the two surgical techniques. We also analyzed the incidence of HPS in infants in the last 10 years in relation to the demographic trend of our province. METHODS We analyzed all the cases of HPS treated at our Unit between January 2010 and December 2019. The data were obtained from operating systems. Data about the demographic trends, in particular, the number of births and the population residing in the province of Verona from 2010 to 2019, were also retrieved. RESULTS During the study period, 60 patients were treated for HPS and met the inclusion criteria. Of these, 56 males and 4 females with an average age of 38±14 days at surgery were included. No differences were found in terms of the duration of surgery, post-operative complications, duration of hospitalization, and weight at the time of surgery. The only statistically significant data was the chlorine level in cases with and without post-operative vomiting (97±3.5 vs. 102±3.3 mmol/L, p<0.05). There was a lower incidence of HPS from 2014 to 2019; however, there was no significant evidence regarding the correlation between this and the reduced birth rate recorded in the province of Verona during the same period. CONCLUSION Although laparoscopic pyloromyotomy is a highly complex procedure, it is a feasible alternative to the classic open technique.

Abstract
PURPOSE Delayed enteral feeding (DEF) contributes to postoperative complications among children undergoing intestinal surgery. Various recent studies indicate the benefits of early enteral nutrition after intestinal surgery in adults. This systematic review and meta-analysis evaluates whether early enteral feeding (EEF) is beneficial in children who underwent intestinal anastomosis. METHODS MEDLINE, PubMed, the Cochrane Library, and Web of Science databases were searched for RCTs that addressed the effect of EEF in children (younger than 18 years old) undergoing intestinal anastomosis. EEF was defined as starting enteral feeding before the 3rd postoperative day. Studies were selected based on predetermined inclusion and exclusion criteria. A meta-analysis was performed using RevMan 5.3 to estimate odds ratios (ORs) or mean differences (MDs) with 95% confidence intervals (CIs). RESULTS Four RCT studies met the inclusion criteria, comprising 97 cases with EEF and 89 cases with DEF. Enteral feeding started significantly earlier in the EEF group compared to the DEF group (MD = - 2.80; 95% CI - 3.11 to - 2.49; p < 0.00001). Postoperative anastomotic leak rate was unchanged between EEF and DEF groups (OR = 0.86; 95% CI 0.17-4.46; p = 0.86). The EEF group had a shorter length of hospital stay (MD = - 3.38; 95% CI - 4.29 to - 2.48; p < 0.00001), earlier time to bowel movement return (MD = - 0.57; 95% CI - 0.79 to - 0.35; p < 0.00001), lower incidence of surgical infection (OR = 0.27; 95% CI 0.08-0.90; p = 0.03), and faster tolerance of full enteral feeding (MD = - 2.00; 95% CI - 3.01 to - 2.79; p < 0.00001). Incidence of fever (OR = 0.37; 95% CI 0.10-1.31; p = 0.12), emesis, and abdominal distention (OR = 0.63; 95% CI 0.13-3.16; p = 0.58) were not different between the two groups. CONCLUSIONS Early enteral feeding after intestinal anastomosis in children does not increase the risk of postoperative anastomotic leak, fever, emesis, and abdominal distention. However, early enteral feeding is beneficial as it promotes the return of bowel function, reduces the length of hospital stay and the incidence of surgical infection in comparison to delayed enteral feeding.

Abstract
Infantile hypertrophic pyloric stenosis is the most common surgical cause of vomiting in infancy. After adequate resuscitation, surgical pyloromyotomy is the standard of care for infants with pyloric stenosis. This article provides a brief overview and updates on hypertrophic pyloric stenosis in infants, with a focus on the surgical approach as well as perioperative management of this pathology. The most controversial aspect of the management of infants with pyloric stenosis is post-pyloromyotomy feeding, as there is no clear consensus in the literature on the best regimen. More randomized controlled trials are needed to establish the optimal resuscitation protocol in the preoperative phase and the ideal feeding regimen in the postoperative phase for infants with hypertrophic pyloric stenosis.

Abstract
INTRODUCTION Traditionally enteral nutrition has been delayed following abdominal surgery in children, to prevent complications. However, recent evidence in the adult literature refutes the supposed benefits of fasting and suggests decreased complications with early enteral nutrition (EEN). This review aimed to compile the evidence for EEN in children in this setting. METHODS Databases Pubmed, EmBase, Medline and reference lists were searched for articles containing relevant search terms according to PRISMA guidelines. First and second authors reviewed abstracts. Studies containing patients less than 18 years undergoing abdominal surgery, with feeding initiated earlier than standard practice, were included. Studies including pyloromyotomy were excluded. Primary outcome was length of stay (LOS). Secondary outcomes included time to full enteral nutrition, time to stool and postoperative complications. RESULTS Fourteen articles met inclusion criteria - five on neonatal abdominal surgery, three on gastrostomy formation and six on intestinal anastomoses. There were three randomized control trials (RCTs), five cohort studies, four historical control trials, one nonrandomized trial and one case series. Nine studies showed a decreased LOS with EEN. Most studies which reported time to full enteral nutrition showed improvement with EEN; however, time to stool was similar in most studies. Postoperative complications were either decreased or not statistically different in EEN groups in all studies. CONCLUSION Studies to date in a limited number of procedures suggest EEN appears safe and effective in children undergoing abdominal surgery. Although robust evidence is lacking, there are clear benefits in LOS and time to full feeds, and no increase in complications. LEVEL OF EVIDENCE IV.

Abstract
BackgroundThe aim of the study was to evaluate how different parameters in the preoperative, perioperative, and postoperative period affect time to full enteral feeding (TFEF) in children undergoing pyloromyotomy.MethodsA retrospective study of all children operated for infantile hypertrophic pyloric stenosis between 2001 and 2017 was conducted. Parameters in demographics and in the preoperative and postoperative period were evaluated against TFEF (hours) using linear regression models.ResultsIn the whole cohort of 175 children, mean TFEF was 47 hours with Standard Deviation (SD) of ±35. In the multivariate model, TFEF decreased with age [beta (B): −0.62; 95% confidence interval (95% CI) −1.05 to −0.19; p=0.005) and increased with the presence of severe underlying disease (congenital heart defect or syndrome) (B: 26.5; 95% CI 3.3 to 49.7; p=0.026). Hence, for every day of age, the time to fully fed decreased by 0.6 hour, and the presence of an underlying disease increased the time to fully fed with over one day. TFEF did not seem to be affected by prematurity, weight loss, symptom duration, preoperative acid/base balance or electrolyte values, surgical method, or method of postoperative feeding.ConclusionsTFEF decreased with higher age and increased in children with a severe underlying disease. These results may be useful in providing adequate parental information regarding what affects TFEF and the length of hospital stay.

Abstract
Background The lingual frenum is a fold of mucous membrane connecting the ventral tongue to the floor of the mouth. In general, lingual frenum serves multiple roles; its main function is to support the tongue and aid in limiting its movement in different directions. Any anatomical or functional deficiency of lingual frenum may have an impact on tongue functions based on its severity. Historically, the absence of lingual frenum was linked to multiple genetic and developmental conditions such as infantile hypertrophic pyloric stenosis, non-syndromic ankyloglossia diseases, and Ehlers–Danlos syndromes and was never reported in otherwise healthy individuals. Case presentation We report the absence of lingual frenum in an otherwise healthy 21-year-old Middle Eastern woman diagnosed during a routine dental examination. Conclusion To the best of our knowledge, this is the first case to be reported in the literature with similar clinical presentation. Even without a significant impact on tongue movement or speech, it is important for health practitioners to be aware of such conditions and evaluation steps for diagnosis and management.

A randomized trial to assess advancement of enteral feedings following surgery for hypertrophic pyloric stenosis. J Pediatr Surg 2017; 52:534-539.

Abstract
PURPOSE The rate of feeding advancement following surgery for hypertrophic pyloric stenosis (HPS) affects length of stay. We hypothesized that: 1) a relaxed feeding regimen following pyloromyotomy would allow infants to achieve feeding goals more quickly without affecting postoperative emesis, and 2) preoperative metabolic derangements would impair the ability to advance feedings following pyloromyotomy. METHODS A prospective, randomized trial compared two postoperative feeding methods. The primary outcome was length of time to tolerate two consecutive goal feeds (GFs). Infants were randomized into the Incremental-arm (N=74), in which infants were gradually advanced on enteral formula, or the Relaxed-arm (N=69), in which infants were allowed to consume up to GF immediately. Preoperative variables, time to GF, preoperative laboratory values, and postoperative emesis were recorded. A p-value less than 0.05 was significant. RESULTS Patient demographics, pyloric ultrasound measurements, and episodes of postoperative emesis were similar between groups. Infants in the Relaxed-arm reached GF more quickly than those in the Incremental-arm and had a shorter length of stay (p<0.001). Infants with preoperative serum chloride less than 100mmol/L reached GF more slowly than those with normal labs (p<0.03). CONCLUSION Following surgery for HPS, surgeons can safely utilize a relaxed, nonstructured feeding regimen, which may allow infants to reach feeding goals more quickly without untoward vomiting.

Abstract
BACKGROUND Hypertrophic pyloric stenosis (HPS) is the most common diagnosis requiring surgery in infants. Electrolytes are used as a marker of resuscitation for these patients prior to general anesthesia induction. Often multiple fluid boluses and electrolyte panels are needed, delaying operative intervention. We have attempted to predict the amount of IV fluid boluses needed for electrolyte correction based on initial values. METHODS A single center retrospective review of all patients diagnosed with HPS from 2008 through 2014 was performed. Abnormal electrolytes were defined as chloride <100mmol/L, bicarbonate ≥30mmol/L or potassium >5.2 or <3.1mmol/L. Patients with abnormal electrolytes were resuscitated with 20ml/kg saline boluses and continuous fluids at 1.5 times maintenance rate. RESULTS During the study period 542 patients were identified with HPS. Of the 505 who were analyzed 202 patients had electrolyte abnormalities requiring IV fluid resuscitation above maintenance, and 303 patients had normal electrolytes at time of diagnosis. Weight on presentation was significantly lower in the patients with abnormal electrolytes (3.8 vs 4.1kg, p<0.01). Length of stay was significantly longer in the patients with electrolyte abnormalities, 2.6 vs 1.9days (p<0.01). Fluid given was higher over the entire hospital stay for patients with abnormal electrolytes (106 vs 91ml/kg/d, p<0.01). The number of electrolyte panels drawn was significantly higher in patients with initial electrolyte abnormalities, 2.8 vs 1.3 (p<0.01). Chloride was the most sensitive and specific indicator of the need for multiple saline boluses. Using an ROC curve, parameters of initial Cl(-)80mmol/L and the need for 3 or more boluses AUC was 0.71. Modifying the parameters to initial Cl(-) ≤97mmol/L and 2 boluses AUC was 0.65. A patient with an initial Cl(-)85 will need three 20ml/kg boluses 73% (95% CI 52-88%) of the time. A patient with an initial Cl(-) ≤97 will need two 20ml/kg boluses at a rate of 73% (95% CI 64-80%). CONCLUSION Children with electrolyte abnormalities at time of diagnosis of HPS have a longer length of stay; require more fluid resuscitation and more lab draws. This study reveals high sensitivity and specificity of presenting chloride in determining the need for multiple boluses. We recommend the administration of two 20ml/kg saline boluses separated by an hour prior to rechecking labs in patients with initial Cl(-) value ≤97mmol/L. If the presenting Cl(-) <85 three boluses of 20ml/kg of saline separated by an hour are recommended. If implemented these modifications have potential to save time by not delaying care for extraneous lab results and money in the form of fewer lab draws.

Abstract
CONTEXT Postoperative emesis is common after pyloromyotomy. Although postoperative feeding is likely to be an influencing factor, there is no consensus on optimal feeding. OBJECTIVE To compare the effect of feeding regimens on clinical outcomes of infants after pyloromyotomy. DATA SOURCES Cumulative Index to Nursing and Allied Health Literature, The Cochrane Central Register of Controlled Trials, Embase, and Medline. STUDY SELECTION Two reviewers independently assessed studies for inclusion based on a priori inclusion criteria. DATA EXTRACTION Data were extracted on methodological quality, general study and intervention characteristics, and clinical outcomes. RESULTS Fourteen studies were included. Ad libitum feeding was associated with significantly shorter length of stay (LOS) when compared with structured feeding (mean difference [MD] -4.66; 95% confidence interval [CI], -8.38 to -0.95; P = .01). Although gradual feeding significantly decreased emesis episodes (MD -1.70; 95% CI, -2.17 to -1.23; P < .00001), rapid feeding led to significantly shorter LOS (MD 22.05; 95% CI, 2.18 to 41.93; P = .03). Late feeding resulted in a significant decrease in number of patients with emesis (odds ratio 3.13; 95% CI, 2.26 to 4.35; P < .00001). LIMITATIONS Exclusion of non-English studies, lack of randomized controlled trials, insufficient number of studies to perform publication bias or subgroup analysis for potential predictors of emesis. CONCLUSIONS Ad libitum feeding is recommended for patients after pyloromyotomy as it leads to decreased LOS. If physicians still prefer structured feeding, early rapid feeds are recommended as they should lead to a reduced LOS.

Abstract
BACKGROUND Hypertrophic pyloric stenosis (HPS) is a condition noted within the first several weeks of life that results in hypertrophy of the pyloric muscle between the stomach and duodenum. The etiology has not been elucidated but genetic and environmental influences are suspected. We hypothesized that agricultural pesticides would be associated with an increased incidence of pyloric stenosis. STUDY DESIGN Data from infants with HPS were obtained from the Indiana Birth Defects Registry (IBDR) for all counties in Indiana from 2005 to 2009. Data from all live births were obtained from the Indiana State Health Department (ISHD). Maternal demographics and clinical characteristics of infants were abstracted. The US Geological Survey (USGS) provided estimated use of agricultural pesticides (EPEST), and these values were correlated with HPS incidence. Univariate and multivariate logistical regression models were used to assess the association between HPS risk and pesticide use. RESULTS A total of 442,329 newborns were studied with 1313 HPS cases recorded. The incidence of HPS was 30/10,000 live births. HPS incidence was correlated with total county pesticide use, as well as subcategories of pesticides (fungicides, fumigants, insecticides, herbicides). Indiana counties were then divided into low, moderate and high pesticide use (mean±standard deviation: 127,722±73,374, 308,401±36,915, and 482,008±97,260pounds of pesticides). Incidence of HPS was 26, 29, and 36 cases per 10,000 in low, moderate and high pesticide-use counties respectively. Subset analysis showed that the positive association between HPS and county pesticide use was more likely for male infants from mothers who were white, aged 20-35 years, had education at high school or lower, and smoked (p<0.05). CONCLUSION Pesticide use correlated significantly with incidence of HPS. Positive correlations between HPS risk and pesticide use were found for most risk factors. Further studies will be needed to verify our findings and further delineate the nature of this correlation.

Abstract
Infantile hypertrophic pyloric stenosis (IHPS) is a common condition in infancy, characterized by an acquired narrowing of the pylorus, which requires surgery. These infants usually present with projectile, nonbilious vomiting, with a palpable 'olive' in the abdomen and sometimes a 'peristaltic wave' after being fed with formula or breast milk. Although IHPS is a common disorder, its etiology is largely unknown. Surgical intervention is the standard treatment, preoperative preparation, however is essential to optimal outcome. In this review, the latest advances in IHPS regarding epidemiology, etiology, diagnostics and treatment will be discussed.
