    About this ebook

    This book describes Gastric Outlet Obstruction, Diagnosis and Treatment and Related Diseases
    Gastric outlet obstruction is a disorder where there is an obstruction in the outlet opening of the stomach (Pylorus), blocking the entrance of ingested food coming from the stomach to the duodenum
    Causes
    In children, gastric outlet obstruction can have two possible causes:
    A. Mechanical obstruction happens when the exit to the stomach is narrowed but the gastric nervous and muscular systems are intact.
    The causes of mechanical obstruction can be perinatal or postnatal.
    The perinatal causes mainly are anatomical anomalies as:
    1. Antral webs,
    2. Congenital gastric atresias,
    3. Pyloric stenosis,
    4. Annular pancreas or
    5. Gastric duplication cysts or
    6. Hyper-trophic pyloric stenosis,
    Most of these manifest at an older age.
    The postnatal causes vary from:
    1. More frequent peptic ulcer disease and healing burns from caustic ingestion
    2. More uncommon causes as eosinophilic gastroenteritis or Crohn’s disease, both infectious and noninfectious.
    The often implicated drugs are:
    1. Non-steroidal anti-inflammatory drugs
    2. Macrolide
    3. Fluoxetine in pregnancy
    4. Opiates
    5. Lipitor
    The frequent causes of luminal obstruction are:
    1. Gastric bezoar
    2. Percutaneous endoscopic gastrostomy tube migration
    3. Malrotation
    4. Gastric polyps
    5. Diaphragmatic hernia
    6. Acute or chronic pancreatitis causing external compression,
    7. Pancreatic pseudocyst,
    8. Hematomas (traumatic or Henoch-Schonlein purpura),
    9. Duodenal hamartoma,
    10. Extrinsic band,
    11. Lymphomas
    B. Functional causes of gastroparesis are neurological causes that could be:
    1. Acute, due to
    a. Viral infections,
    b. Electrolyte anomalies
    c. Surrounding tissue inflammation
    2. Chronic as seen in
    a. Uncontrolled diabetes
    b. Intrinsic muscular diseases
    Symptoms
    Vomiting
    Epigastric pain
    Constipation
    Loss of weight
    Hypo-kalemia and metabolic acidosis
    Satiety
    Abnormal enlargement of the stomach
    Diagnosis:
    Physical Assessment
    An abdominal X-ray
    Endoscopic gastrostomy
    Abdominal ultrasound
    CT scan abdomen
    Electrolytes levels
    Treatment:
    Proton pump inhibitors
    Nasogastric suction
    Electrolytes replacement
    Surgical treatment:
    Antrectomy is the surgical removal of the antrum, the part of the stomach just inside the pylorus
    Vagotomy involves cutting one or more branches of the Vagus nerve to reduce gastric acid
    Billroth I is the removal of the Pylorus followed by the connection of the proximal stomach to the duodenum.
    The operation is for the treatment of peptic ulcer and gastric cancer
    Gastrojejunostomy or Billroth II is a surgical procedure that develops a connection between the jejunum (the middle part of the small intestine between the duodenum and ileum) and the stomach
    Parenteral Nutrition
    Supplementary nutrients through Total Parenteral Nutrition (TPN) or Distal feeding tube are helpful among patients with gastric outlet obstruction since their nutritional status normally gets worse.
    Children:
    In children, the doctors attempt to treat most cases conservatively.
    The large percentage of these patients manifest with significant esophageal and gastric irritation due to obstruction of flow and acid reflux
    They hence need adjunct medical therapy with:
    1. Proton pump inhibitors,
    2. Sucralfate or
    3. Steroids.
    With an advanced endoscopic approach the doctors can do:
    1. Pneumatic dilations,
    2. Placement of stents,
    3. Ablation of antral webs or
    4. Injection of Botox,
    But most children require surgical interventions with
    1. Antral web resection,
    2. Partial gastrectomy,
    3. Antrectomy or
    4. Billroth II operation.
    The use of stents to allow passage of food is a new treatment

      Introduction

      I have been writing medical articles for my blog: http://kennethkee.blogspot.com (A Simple Guide to Medical Disorder) for the benefit of my patients since 2007.

      My purpose in writing these simple guides was for the health education of my patients.

      Health Education was also my dissertation for my Ph.D (Healthcare Administration).

      I then wrote an autobiolographical account of his journey as a medical student to family doctor on his other blog: http://afamilydoctorstale.blogspot.com.

      This autobiolographical account A Family Doctor’s Tale was combined with my early A Simple Guide to Medical Disorders into a new Wordpress Blog A Family Doctor’s Tale on http://kenkee481.wordpress.com.

      From which many free articles from the blog was taken and put together into 800 eBooks.

      Some people have complained that the simple guides are too simple.

      For their information they are made simple in order to educate the patients.

      The later books go into more details of medical disorders.

      The first chapter is always from my earlier blogs which unfortunately tends to have typos and spelling mistakes.

      Since 2013, I have tried to improve my spelling and writing.

      As I tried to bring the patient the latest information about a disorder or illness by reading the latest journals both online and offline, I find that I am learning more and improving on my own medical knowledge in diagnosis and treatment for my patients.

      Just by writing all these simple guides I find that I have learned a lot from your reviews (good or bad), criticism and advice.

      I am sorry for the repetitions in these simple guides as the second chapters onwards have new information as compared to my first chapter taken from my blog.

      I also find repetition definitely help me and maybe some readers to remember the facts in the books more easily.

      I apologize if these repetitions are irritating to some readers.

      Chapter 1

      Gastric outlet obstruction

      What is Gastric Outlet Obstruction?

      Gastric outlet obstruction is a disorder where there is an obstruction in the outlet opening of the stomach (Pylorus), blocking the entrance of ingested food coming from the stomach to the duodenum.

      What are the Causes of Gastric Outlet Obstruction?

      Gastric Outlet Obstruction Causes

      Children

      In children, gastric outlet obstruction can have two possible causes, mechanical and functional.

      A. Mechanical obstruction happens when the exit to the stomach is narrowed but the gastric nervous and muscular systems are intact.

      The causes of mechanical obstruction can be perinatal or postnatal.

      The perinatal causes mainly are anatomical abnormalities as:

      1. Antral webs,

      2. Congenital gastric atresias,

      3. Pyloric stenosis,

      4. Annular pancreas or

      5. Gastric duplication cysts or

      6. Hyper-trophic pyloric stenosis,

      Most of these manifest at an older age.

      On the other hand, the postnatal causes vary from:

      1. More frequent peptic ulcer disease or drug-induced gastric ulcers and healing burns from caustic ingestion

      2. More uncommon causes as eosinophilic gastroenteritis or Crohn’s disease and other granulomatous diseases, both infectious
