Hypertrophic pyloric stenosis in children

BACKGROUND: Definitive surgical care is often delayed in hypertrophic pyloric stenosis (HPS). Our aim is to evaluate the effect modifiable factors in preoperative HPS management have on efficiency of care. METHODS: A retrospective review of all patients undergoing pyloromyotomy for HPS at two US children's hospitals between 2008 and 2018 was performed. RESULTS: 406 patients were included in the study. The majority (310, 76 ​%) were adequately resuscitated and ready for surgery upon diagnosis in the ER...

INTRODUCTION AND IMPORTANCE: The association in the occurrence of hypertrophic pyloric stenosis (HPS) is 0.25 % to 0.44 % between monozygotic twins and 0.05 % to 0.10 % in dizygotic twins. A combination of genetic and environmental factors may have contributed to the occurrence of HPS. In view of the few related cases reported recently, we present two dizygotic twins who were diagnosed with HPS. CASE PRESENTATION: This report describes a rare case of congenital infantile hypertrophic pyloric stenosis in preterm dizygotic twins diagnosed early, in which the first case presented with severe clinical features and managed surgically while the second presented with moderate features and hence managed non-operatively with atropine for 14 days...

BACKGROUND: Pyloromyotomy, the treatment for infants with hypertrophic pyloric stenosis, is a procedure with a low risk of complications and quick recovery. We describe a rare and fatal complication. CASE DESCRIPTION: A 12-year old boy presents with persistent abdominal pain and vomiting at his general practitioner. After he collapses, cardiopulmonary resuscitation is started and he is brought to the hospital where he died. His medical history mentioned pyloromyotomy, complicated by fascia dehiscence and recurrent abdominal pain since the age of six...

Plain abdominal radiographs and gastrointestinal contrast studies remain the first line of investigation for the evaluation of several conditions due to their easy availability and ease of use in pediatric patients. A systematic approach to evaluating the plain radiograph for pediatric abdomen can lead the radiologist to a relevant differential diagnosis in most cases. In other cases, it leads the radiologist to the next line of investigation. The plain radiograph of the abdomen is requested for several conditions ranging from abdominal pain, vomiting, failure to pass meconium, abdominal distension, perforation, mass or for suspected obstruction...

BACKGROUND: Neonates may undergo surgery because of malformations such as diaphragmatic hernia, gastroschisis, congenital heart disease, and hypertrophic pyloric stenosis, or complications of prematurity, such as necrotizing enterocolitis, spontaneous intestinal perforation, and retinopathy of prematurity that require surgical treatment. Options for treatment of postoperative pain include opioids, non-pharmacological interventions, and other drugs. Morphine, fentanyl, and remifentanil are the opioids most often used in neonates...

Hypertrophic pyloric stenosis is a common cause of vomiting in the first few weeks of life, but in rare cases, it may occur in older subjects with a major risk of delayed diagnosis and complications. We describe the case of a 12-year-and-8-month-old girl who presented to our department for epigastric pain, coffee-ground emesis, and melena, which arose after taking ketoprofen. An abdomen ultrasound showed thickening (1 cm) of the gastric pyloric antrum, while upper-GI endoscopy documented esophagitis and antral gastritis with a non-bleeding pyloric ulcer...

OBJECTIVE: Infant exposure to macrolide antibiotics is a risk factor for infantile hypertrophic pyloric stenosis (IHPS). The aim of the study was to establish whether perinatal exposure to non-macrolide antibiotics was a risk factor for IHPS. STUDY DESIGN: A retrospective matched case-control study was performed using a database including all children born at Soroka University Medical Centre between 2006 and 2018. Cases and controls were compared using Student T-test and multiple logistic regression...

BACKGROUND/PURPOSE: Bedside point-of-care ultrasound scans are a cheap, quick and safe diagnostic tool. There is increasing evidence for the use of point-of-care surgeon-performed ultrasound scans in adults, however there are fewer studies of its use in children. This systematic review aims to provide an up-to-date summary of the evidence behind surgeon-performed ultrasound scans in paediatric surgery. METHODS: The PubMed database was used to conduct this systematic review between the dates 1 Jan 1980 to 1 June 2020 (last search: 1 June 2020)...

BACKGROUND: Hypertrophic pyloric stenosis is a condition in newborns in which the hypertrophic pyloric muscle causes gastric obstructive symptoms of progressive vomiting leading to hypochloremic hypokalemic metabolic alkalosis. The main aim of the research was to assess whether, based on the acid-base status, we can distinguish newborns who vomit due to pylorostenosis, compared with newborns who vomit for other unspecific reasons. METHODS: The electronic records of patients in the hospital information system treated under the diagnosis Q40...

BACKGROUND: Hypertrophic pyloric stenosis in otherwise healthy neonates frequently requires urgent surgical procedure but anaesthesia care may result in respiratory complications, such as hypoxaemia, pulmonary aspiration of gastric contents, and postoperative apnoea. The primary aim was to study whether or not the incidence of difficult airway management and of hypoxaemia in neonates undergoing pyloric stenosis repair was higher than that in neonates undergoing other surgeries. METHODS: Data on neonates and infants undergoing anaesthesia and surgery for pyloric stenosis were extracted from the NEonate and Children audiT of Anesthesia pRactice In Europe (NECTARINE) database, for secondary analysis...

INTRODUCTION: Congenital hypertrophic pyloric stenosis (CHPS), the most common infantile disease requiring surgical intervention, is routinely treated with open or laparoscopic pyloromyotomy. Recently, gastric peroral endoscopic pyloromyotomy (G-POEM) has been used for adult gastroparesis. We aimed to evaluate the efficacy and safety of G-POEM in treating infantile CHPS. METHODS: We reviewed data from 21 G-POEM-treated patients at 3 tertiary children's endoscopic centers in China between January 2019 and December 2020...

INTRODUCTION: Ultrasound is the examination of choice for the diagnosis of hypertrophic pyloric stenosis (HPS). A correct diagnosis is dependent on the technique and measurement accuracy. However, in the world literature there is a wide range of values suggested for the diagnosis of this condition. The current minimum measurements used to diagnose HPS seem excessively large, and therefore, we set out to redefine these values. METHODS: A retrospective study was performed on 607 patients (615 scans) being investigated for HPS...

INTRODUCTION: Point-of-care ultrasound (POCUS) use is increasing in pediatric clinical settings. However, gastric POCUS is rarely used, despite its potential value in optimizing the diagnosis and management in several clinical scenarios (i.e., assessing gastric emptying and gastric volume/content, gastric foreign bodies, confirming nasogastric tube placement, and hypertrophic pyloric stenosis). This review aimed to assess how gastric POCUS may be used in acute and critically ill children...

BACKGROUND: Mass drug administration (MDA) is a strategy to improve health at the population level through widespread delivery of medicine in a community. We surveyed the literature to summarize the benefits and potential risks associated with MDA of antibacterials, focusing predominantly on azithromycin as it has the greatest evidence base. MAIN BODY: High-quality evidence from randomized controlled trials (RCTs) indicate that MDA-azithromycin is effective in reducing the prevalence of infection due to yaws and trachoma...

Background: Biannual mass azithromycin administration reduces all-cause childhood mortality in some sub-Saharan African settings, with the largest effects in children aged 1-5 months. Azithromycin has not been distributed to children <1 month due to risk of infantile hypertrophic pyloric stenosis (IHPS). Methods: This 1:1 placebo-controlled trial, randomized neonates aged 8-27 days to a single oral dose of azithromycin (20 mg/kg) or equivalent volume of placebo in 5 regions of Burkina Faso during 2019 and 2020...

PURPOSE: A new novel technique for the treatment of pediatric hypertrophic pyloric stenosis (HPS), transumbilical single-site laparoscopic pyloromyotomy with a single instrument (TUSSLP), was introduced. TUSSLP was compared with the transabdominal three-site laparoscopic pyloromyotomy (TATSLP) procedure. METHODS: Patients with HPS who underwent TUSSLP and TATSLP between January 2016 and September 2020 were assigned to group A and group B, respectively. The descriptive variables, perioperative clinical characteristics and postoperative follow-up results were retrospectively analyzed and compared between the 2 groups...

Infants with hypertrophic pyloric stenosis are usually diagnosed at about 3 to 8 weeks of age. The clinical onset of symptoms in preterm babies is observed normally at a later age than in term or post-term newborns. This report describes a rare case of a 2-day old preterm twin girl presenting with drinking laziness and recurrent vomiting. Five days after the beginning of symptoms and after several studies, including an upper gastrointestinal contrast study, the diagnosis of hypertrophic pyloric stenosis was made and confirmed at surgery...

PURPOSE: Pyloromyotomy for hypertrophic pyloric stenosis (HPS) is one of the most common non-elective operations performed in the neonatal period. This project aims to explore outcomes of pyloromyotomy and compare differences between laparoscopic versus open pyloromyotomies in newborns diagnosed with HPS. METHODS: The Nationwide Readmissions Database (NRD) from 2010 to 2014 was queried to identify patients diagnosed with HPS that underwent repair. RESULTS: In total, 30,915 children (18% female) underwent pyloromyotomy for HPS...

BACKGROUND: To examine factors that affect the severity of pyloric hypertrophy, post-operative feeding and nutritional recovery in infantile hypertrophic pyloric stenosis (IHPS). MATERIAL AND METHODS: Medical records of infants diagnosed with IHPS at a single tertiary center between 2009 and 2018 were retrospectively reviewed. Clinical characteristics, biochemistry data and outcome were assessed for their association with the severity of pyloric hypertrophy and post-operative recovery...

BACKGROUND: The causes of idiopathic ileocolic intussusception are unknown, with infection as the most likely culprit. Recently, social distancing measures were implemented during the coronavirus disease 2019 (COVID-19) pandemic to decrease transmissible infectious diseases, creating an opportune setting to study the role of infection on the pathogenesis of intussusception on a population level. OBJECTIVE: To investigate the impact of social distancing on intussusception...
