    Gastric Outlet Obstruction (Stenosis) : Lior Shlomov 1852

    Uploaded by

    Lior Shlomov
    Gastric outlet obstruction (GOO) occurs when there is a mechanical obstruction to gastric emptying. GOO has benign and malignant causes. Benign causes include peptic ulcer disease, gastric polyps, and pancreatic pseudocyst. Malignant causes are pancreatic carcinoma, gastric adenocarcinoma, ampullary cancer, and duodenal cancer. Symptoms include frequent vomiting, retention, bloating, epigastric pain, and weight loss. Diagnosis involves physical exam, labs, imaging, and endoscopy. Treatment depends on the cause but may include medical management, endoscopic procedures, or surgery such as antrectomy or vagotomy.

    Gastric outlet obstruction

    (stenosis)
    Lior Shlomov
    1852
     Gastric outlet obstruction (GOO, also known as pyloric obstruction) is not a
    single entity
     It is the clinical and pathophysiological consequence of any disease process
    that produces a mechanical obstruction to gastric emptying.
     Clinical entities that can result in GOO generally are categorized into two
    well-defined groups of causes: benign and malignant.
    Etiology-

     Benign causes are –


    1) Peptic ulcer disease
    2) Gastric polyps
    3) Hypertrophic Pyloric stenosis
    4) Congenital duodenal web
    5) Pancreatic pseudocyst
     Malignant causes-
    1) Pancreatic carcinoma
    2) Gastric adenocarcinoma
    3) Ampullary cancer
    4) Duodenal cancer
    Symptoms-

     Frequent vomiting (1 hour after a meal)


     Retention, bloating and epigastric fullness.
     Epigastric pain
     Weight loss
    Diagnosis-

     Physical examination – severe dehydration and malnutrition , may be


    tympanic mass over epigastric area.
    *succussion splash sign - splash-like sound heard over the stomach in the left
    upper quadrant of the abdomen on shaking the patient.
     Laboratory examination – hypochromic, hypokalemic metabolic alkalosis.
     Abdominal X-ray may show a gastric fluid level which would support the
    diagnosis.
     The most confirmatory investigation is endoscopy of upper gastrointestinal
    trac
    Treatment

     Depends on the cause, but is usually either surgical or medical.


     Medical (if its reversible)
     Endoscopic balloon dilation therapy
     Surgical-
    Antrectomy ( removal of the antral portion of the stomach)
    vagotomy
