Complications of Peptic Ulcer Disease!

 COMPLICATIONS OF PEPTIC ULCER DISEASE

  1. Bleeding peptic ulcer
  2. Pyloric stenosis
  3. Zollinger-Ellison Disease
  4. Stress Ulcers


Bleeding peptic ulcer:

  • Peptic ulcer is the most common cause of non-variceal upper gastro-intestinal bleeding.
  • Most patients with bleeding peptic ulcer are clinically stable and stop bleeding without any intervention, whereas other outcomes include re-bleeding and mortality.
  • Endoscopy allows identification of the severity of disease.
  • Endoscopic hemostatic therapy which is successful in reducing mortality.
  • A number of pharmacological agents have been used for endoscopic injection therapy such as 1:10000 adrenaline (epinephrine), human thrombin and fibrin glue.
  • Mechanical endoscopic treatment options include Thermocoagulation using a heater probe or endoscopic clipping.
  • Combination therapies are superior to monotherapy and a combination of adrenaline 1:10000 with either thermal or mechanical treatment is recommended (SIGN,2008).



Pyloric Stenosis:

Malignancy is the most common cause of gastric outlet obstruction.
Peptic ulcer disease is the underlying cause in about 10% of cases.
Conventional treatment with acid-suppressive therapy may also help.
If medical therapy fails to relieve the obstruction, Endoscopic balloon dilation or surgery may be required.


Zollinger-Ellison Syndrome:

  • This is a rare syndrome that consists of a triad of non-beta cell tumors of the pancreas that contain and release gastrin, gastric acid hypersecretion and severe ulcer disease.
  • Extra-pancreatic gastrinomas are also common and may be frequently found in the duodenal wall.
  • A proportion of these patients have tumors of the pituitary gland and parathyroid gland.
  • Patients with idiopathic peptic ulcer disease should be investigated for Zollimger-Ellison Syndrome.
  • Medical management includes; greater than standard doses of Proton Pump Inhibitors. The somatostatin analogue OCTREOTIDE is also effective but has no clear advantage over PPIs.


Stress Ulcers:

  • Sever physiological stress such as Head Injury, Spinal cord injury, Burns, Multiple traumas or Sepsis may induce superficial mucosa erosions or gastroduodenal ulcerations. These may lead to hemorrhage or perforation.
  • Diminished blood flow to the gastric mucosa, decreased cell renewal, diminished prostaglandin production and hypertension are involved in causing stress ulceration.
  • Management involves: Intravenous acid-suppression therapy, Histamine H-receptor antagonists, PPIs and Nasogastric tube administration of SUCRALFATE (4-6g daily in divided doses) have been used to prevent stress ulceration in the intensive care unit until patient tolerates enteral feeding.
Most commonly used regimens are: IV Ranitidine 50mg every 8hr reducing to 25mg in severe renal impairment.
  • Patients at Mechanical ventilation and the presence of coagulopathies are at higher risks of stress-related mucosal bleeding and may require prophylactic treatment.

Diabetes Mellitus: Clinical Presentation and Diagnosis!

 CLINICAL PRESENTATION AND DIAGNOSIS OF DM 2. SCREENING American Diabetes Association (ADA) recommends routine screening for T2 DM every 3 years in all adults starting at 45 years of age. Testing of T2 DM should be considered in any adult, regardless of their age, who have a BMI greater than or equal to 25kg/m2. The ADA does not currently recommend widespread screening for T1 DM because of the relatively low incidence in the general population, although measurement of Islet antibodies may be appropriate for high-risk individuals. 3.GESTATIONAL DIABETES: "Gestational diabetes is the glucose intolerance in women during pregnancy". All pregnant women who have risk factors for T2 DM should be screened for undiagnosed T2 DM at their first prenatal visit using standard diagnostic criteria.  Any women found to have diabetes in the early point at pregnancy is considered to have T2 DM or GDM. All other pregnant women, not currently known to have DM should be screened for GDM with a 75...

Hospital Acquired Pneumonia- Definition, Predisposing Factors, Clinical Features and Management!

 HOSPITAL ACQUIRED PNEUMONIA Definition: "HAP refers to a new episode of pneumonia occurring at least 2 days after the administration to hospital. It is the most common Hospital Acquired Infection (HAI) and leading cause of HAI-associated death". Predisposing factors: Aspiration of nasopharyngeal secretion Bacteria introduced into the lower GIT. Bacteriaemia Old age Mode of Spread:  Droplet infection Infecting agent: Bacteria: S.pneumonia , S.aureus , H.influenza Virus: Adenovirus, Corona virus, Herpes Simplex Clinical Features: Purulent sputum New radiological infiltrates Temperature > 38 degree Celsius Leukocytosis Investigations: Chest Pain:  to confirm the diagnosis and exclude complication. Pulse Oximetry : to monitor response to oxygen therapy, if SaO2 < 93% features of sever pneumonia, identify ventilatory failure or acidosis. Cell count:  ESR, Neutrophil leukocytosis Microbiological studies:  for severe CAP and those that do not respond to ...

Management of H.pylori and NSAID-associated ulcers Eradication!

MANAGEMENT FOR H.PYLORI ERADICATION It is known that H.pylori infection is associated with over 90% of duodenal ulcers and 80% of Gastric Ulcers. Antibiotics alone or acid-suppressing agents alone, do not eradicate H.pylori . Both therapies act synergistically as growth of the organism occurs at elevated pH and antibiotics efficacy is enhanced during growth. Additionally, increasing intragastric pH may enhance antibiotic absorption. High eradication rates are achieved by a short course of Triple Therapy consisting of:            1 .PPI                                         2. Clarithromycin                         3. Amoxicillin/Metronidazole          in a twice recommended simultaneous regimen. First-Line Therapy :  European Guidelines recommended 1 we...
