Abdwall pain1

  1. 1. Who are they?
  2. 2. ?
  3. 3. ?
  4. 4. They all went on the Disable List (DL) What reason?
  5. 5. Hint: One movement in common
  6. 6. Abdominal Wall Pain
  7. 7. Accounts for about 10% of patientswith chronic idiopathic abdominal pain seen in gastroenterological practices.
  8. 8. Anatomy
  9. 9. Abdominal Wall Pain suspected• chronic and unremitting, with minimal or no relationship to eating or bowel function but often a relationship to posture (i.e., lying, sitting, standing),• Most commonly, abdominal wall pain is related to cutaneous nerve root irritation or myofascial irritation.• The pain can also result from structural conditions, such as localized endometriosis or rectus sheath hematoma, or from incisional or other abdominal wall hernias.• If hernia or structural disease is excluded, injection of a local anesthetic with or without a corticosteroid into the pain trigger point can be diagnostic and therapeutic.
  10. 10. Features of Intra-abdominal Pain
  11. 11. Etiology of Abdominal Wall Pain ?
  12. 12. Hernia• Protuberance in abdominal wall that usually decreases in size when patient is supine• Abdominal CT scanning, abdominal ultrasonography, herniography
  13. 13. Sports HerniaProblem is due to a weakening in the same abdominal wall muscles,but there is no palpable hernia.Sports hernia typically begins with a slow onset of aching pain in thelower abdominal region. Symptoms may include:Pain in the lower abdomenPain in the groinPain in the testicle (in males)Surgery
  14. 14. Causes• The most common cause appears to be entrapment of an anterior cutaneous branch of one or more thoracic intercostal nerves;• myofascial pain and radiculopathy are less frequent
  15. 15. Rectus Nerve Entrapment• Occurs along lateral edge of rectus sheath; worsening of pain with tensing of muscles• Injection of local anesthetic
  16. 16. Thoracic lateral cutaneous nerve entrapment• Occurs spontaneously, after surgery or during pregnancy• History and physical examination
  17. 17. Ilioinguinal and iliohypogastric nerve entrapment• Lower abdominal pain that occurs after inguinal hernia repair• History and physical examination
  18. 18. Endometriosis• Cyclic abdominal pain• Laparoscopy
  19. 19. Diabetic radiculopathy• Acute, severe truncal pain involving T6-T12 nerve roots• Paraspinal EMG
  20. 20. Abdominal Wall Tear• Occurs mainly in athletes• History and physical examination• Abdominal wall hematoma
  21. 21. Other Causes• Complication of abdominal laparoscopic procedures• Spontaneous rectus sheath hematoma• Herpes zoster• Spinal nerve irritation• Slipping rib syndrome• Myofascial pain
  22. 22. Carnetts sign for patients with Abdominal Pain• The examiner places his or her finger on the tender area of the patients abdomen and asks the patient to raise both legs off the table.• An increase in the patients pain during this maneuver is considered a positive test.
  23. 23. Significance of Carnetts sign• The idea of Carnetts sign is that (acute) abdominal pain remains unchanged or increases when the muscles of the abdominal wall are tensed.• if Pain source is Intra-Abdominal (Negative Carnetts Sign),Abdominal Pain decreases with tensing abdomen.• And in Abdominal Muscle Wall Pain (Positive Carnetts Sign), Pain increases or remains unchanged
  24. 24. Technique• Patient lies supine• Patient tenses abdominal wall by• Asking the patient to lift the head and shoulders from the examination table to tense the abdominal muscles• An alternative is to ask the patient to raise both legs with straight knees.
  25. 25. Psychological• If the distress caused by a patients pain seems out of proportion to other findings, the presence of depression or other psychologic dysfunction should be considered.• Pain that would normally be a minor nuisance can become the focus of somatization and be greatly magnified by depression.• A tricyclic antidepressant, given in a low dosage that minimizes sedation and anticholinergic side effects, can be helpful in providing pain relief.• Selective serotonin reuptake antagonists may be less effective than tricyclic antidepressants for the relief of chronic pain.
  26. 26. Trial of Local Anesthetic• The trigger point for abdominal wall pain can be treated with injection of a small volume of local anesthetic.• Once the patient identifies the trigger point with one finger, the physician “marches” his or her fingers around the area to identify the center of the tender spot, which is usually 1 to 2 cm in diameter.• A tuberculin syringe with a 5/8-inch needle is then used to inject a few tenths of a milliliter of 1 percent lidocaine (Xylocaine) into the most tender spot.• A longer needle may be needed in an obese patient. The trigger point is identified when the tip of the needle causes marked tenderness.• The injection of local anesthetic serves as a therapeutic trial and may not provide permanent relief. However, a significant number of patients experience pain relief after one or two injections.• A major goal of trigger-point injection is to confirm the abdominal wall as the pain source. In addition, this simple maneuver can help persuade a skeptical patient that the abdominal wall is, indeed, the source of pain
  27. 27. Physiatrist Prescription?
  28. 28. Therapeutic Prescription• Support• Thermotherapy• Stretches• Strengthening• Return to Activity
  29. 29. Features of Abdominal Wall Pain• Some Pain often constant or fluctuating; less often, episodic• Pain intensity possibly related to posture (e.g., lying, sitting, standing)• Pain not related to meals or bowel function• No findings of an intra-abdominal process (see Table 1)• Abdominal tenderness unchanged or increased when abdominal wall is tensed (positive Carnetts sign)• Discrete, tender pain trigger point no more than a few centimeters in diameter• Trigger points often found along lateral margins of the rectus abdominis muscles or at attachments of muscle or fascia• With stimulation of trigger point, referral of pain or spreading of pain over a large area
