The goal of treatment is luminal enlargement to improve obstructive symptoms such as nausea, vomiting, abdominal pain, obstipation or bowel obstruction.

ABSTRACT Background: Infantile hypertrophic pyloric stenosis (IHPS) is an exceedingly rare cause of postoperative emesis in a case of hiatal hernia. Occasionally it may simulate other etiology of gastric outlet obstruction. Case Presentation: A 32-day-old male baby presented with respiratory distress and vomiting since birth. Diagnosis of eventra- tion of left hemi diaphragm was made on CT Chest. At surgery, hiatal hernia with an intrathoracic stomach was found, which was repaired. On 5th postoperative day, the baby developed vomiting after feeding which gradually turned to be projectile in nature over a week. Contrast meal performed showed malpositioned stomach with delayed emptying. At re-operation, a well- formed olive of pylorus was encountered; Ramstedt pyloromyotomy was done.

  • Approach to Pediatric Vomiting.” These Podcasts Are Designed to Give Medical Students an Overview of Key Topics in Pediatrics
    PedsCases Podcast Scripts This is a text version of a podcast from Pedscases.com on “Approach to Pediatric Vomiting.” These podcasts are designed to give medical students an overview of key topics in pediatrics. The audio versions are accessible on iTunes or at www.pedcases.com/podcasts. Developed by Erin Boschee and Dr. Melanie Lewis for PedsCases.com. August 25, 2014. Approach to Pediatric Vomiting (Part 1) Introduction Hi, Everyone! My name is Erin Boschee and I’m a medical student at the University of Alberta. This podcast was reviewed by Dr. Melanie Lewis, a General Pediatrician and Associate Professor at the University of Alberta and Stollery Children’s Hospital in Edmonton, Alberta, Canada. This is the first in a series of two podcasts discussing an approach to pediatric vomiting. We will focus on the following learning objectives: 1) Create a differential diagnosis for pediatric vomiting. 2) Highlight the key causes of vomiting specific to the newborn and pediatric population. 3) Develop a clinical approach to pediatric vomiting through history taking, physical exam and investigations. Case Example Let’s start with a case example that we will revisit at the end of the podcasts. You are called to assess a 3-week old male infant for recurrent vomiting and ‘feeding difficulties.’ The ER physician tells you that the mother brought the baby in stating that he started vomiting with every feed since around two weeks of age. In the last three days he has become progressively more sleepy and lethargic. She brought him in this afternoon because he vomited so forcefully that it sprayed her in the face.

  • Pediatric Abdominal Pain an Emergency Medicine Perspective
    Pediatric Abdominal Pain An Emergency Medicine Perspective a, b Jeremiah Smith, MD *, Sean M. Fox, MD KEYWORDS Functional constipation Pyloric stenosis Necrotizing enterocolitis Appendicitis Incarcerated inguinal hernia Gonadal torsion Functional gastrointestinal disorder KEY POINTS Avoid diagnostic momentum, especially when evaluating functional constipation and functional gastrointestinal disorders. Bilious vomiting in a neonate is a surgical emergency until proven otherwise. Always consider gonadal torsion in a child with lower abdominal pain. Do not overlook the potential for psychosocial causes of abdominal pain. Constipation is not an innocuous condition. BACKGROUND Pediatric abdominal pain is a common complaint evaluated in emergency depart- ments (EDs). Although often due to benign causes, the varied and nonspecific presen- tations present a diagnostic challenge. Emergency care providers are tasked with the difficult job of remaining vigilant for the rare, yet devastating conditions while sorting through the much more common, benign causes of abdominal pain. This task is akin to finding the needle in the haystack. Diagnostic momentum can further threaten to divert the provider’s attention from the true cause. Pediatric abdominal pain is a challenging complaint to evaluate and deserves specific attention. EPIDEMIOLOGY Overall, 5% to 10% of all ED visits by pediatric patients are for abdominal pain.1,2 In the United States alone, up to 38% of school-aged children complain of abdominal Disclosures: The authors have nothing to disclose. a Department of Emergency Medicine, Carolinas Medical Center, 1000 Blythe Boulevard, MEB Floor 3, Charlotte, NC 28203, USA; b Emergency Medicine Residency Program, Department of Emergency Medicine, Carolinas Medical Center, 1000 Blythe Boulevard, MEB Floor 3, Charlotte, NC 28203, USA * Corresponding author.

  • Antro-Pyloric Stenosis and Ectopic Pancreas Carcinoma: What Is This?
    Case Report Annals of Clinical Case Reports Published: 05 Jun, 2016 Antro-Pyloric Stenosis and Ectopic Pancreas Carcinoma: What is This? De Simone B1*, Catena F1 and Charre L2 1Department of Trauma and Emergency Surgery, University Hospital of Parma, Italy 2Centre Hospitalier Renée Dubos, Service de Chirurgie Digestive et Epatobiliare, France Abstract Ectopic pancreas (EcP) is an uncommon congenital anomaly that can be found anywhere along the Gastro-Intestinal tract, most frequently in the stomach (antrum), in the duodenum or in the jejunum. EcP is often asymptomatic and benign, but it can show the same pathological features of the pancreas gland, even malignant transformation. Preoperative diagnosis is difficult. The prognosis of adenocarcinoma developed from ectopic pancreas is still unknown. We report the clinical case of a female 67 years old patient, admitted in our department for vomiting. The aim of our case report with review of the literature is to highlight that in clinical practice EcP is a rare pathological condition but it has to be considered in the differential diagnosis of upper gastrointestinal tract disease, because of the risk of malignant degeneration. Keywords: Ectopic pancreas; Submucosal gastric cancer; Wedge resection; Laparoscopy; Endoscopy Introduction Ectopic pancreas (EcP) is an uncommon congenital anomaly defined as pancreatic tissue abnormally situated, without connection to the normal pancreas but provided with its own vascular and ductal system, as a result of fetal migration of pancreatic tissue during gastrointestinal formation with further development in ectopic area [1-3]. The first case report of heterotopic pancreas was presented in 1729 by Schultz [1,3,4] and the first histopathological description was made in 1859 by Klob [1-3]; it has been found in 0.6-13% of autopsies [1-5] and most of the patients affected are asymptomatic.
