  • 1. . PRESENTED BY: INUSAH ADAMS (Ternopil State Medical Univ.) Nov, 2013
  • 2. PLAN OF PRESENTATION  DEFINITION  EPIDEMIOLOGY  TYPES  ANATOMY  ETIOLOGY  PATHOGENESIS  SIGNS &SYMPTOMS  DIAGNOSIS/INVESTIGATIONS  DIFFERENTIALS  TREATMENT  COMPLICATIONS  HERNIORRHAPHY  PROGNOSIS
  • 3. What is hernia?  It is the outlet of the visceral organs from their physiological placement through natural channels or defects of the abdominal and pelvic wall.
  • 4. Epidemiology Hernias comprise approximately 7% of all surgical outpatient visits.  Male: female ratio is 8:1.  They affect 1-3% of young children.  In men, the incidence rises from 11 per 10,000 person-years, aged 16-24 years,  200 per 10,000 person-years, aged 75 years or above.[1] 
  • 5. Classification of abdominal Hernias? hernias  Etiology: Congenital and acquired  1. 2. 3. 4. 5. 6. • • Anatomical location Inguinal hernia Femoral hernia Umbilical hernia Epigastric hernia Diaphragmatic hernia Incisional/recurrent hernia clinical presentations: incarcerated hernia (complete and incomplete), reducible and nonreducible, complicated and noncomplicated. External (through wall of abdomen) and internal (through the peritoneum) hernias
  • 6. What is the etiology of hernia? Risk factors are:  Malformation of abdominal wall  sex  age  hereditary  Obesity  Ascites  weight loss  postoperative scar  improper weight lifting  Chronic Constipation  chronic cough  pregnancy
  • 7. What is the pathogenesis of hernia? 1. 2. 3. incomplete closure of the abdominal wall in case of congenital hernia increased abdominal pressure increasing dehiscence of fascial structure with accompanying loss of abdominal wall strength
  • 8. Where are the most common sites of hernias?
  • 9. Describe the inguinal canal Site: is situated just above the medial half of the inguinal ligament.  Content: It transmits the spermatic cord (male) and the round ligament (female); the ilioinguinal nerve.  Length: approx.. 3.75 to 4 cm (4-5cm)  Direction: It is obliquely directed anteroinferiorly and medially  Boundaries/walls: Superior wall: fasciae of internal oblique and transversal abdominal muscles Inferior wall: inguinal ligament Anterior wall: fascia of a external oblique abdominal muscle Posterior wall: fascia of transverse abdominal muscle 
  • 10. What is inguinal hernia? hernia in which a loop of intestine enters the inguinal canal  They make up 75% of all abdominal wall hernias  Types of inguinal hernia Direct and indirect -Reducible vs. irreducible -Strangulated hernias -unilateral or bilateral
  • 11. .
  • 12. . Indirect inguinal hernia: protrusion of parts of the intestines into the inguinal canal via the internal/deep inguinal ring. Its sac is lateral to the inferior epigastric artery  Direct inguinal canal: protrusion of parts of the intestines into the inguinal canal through a weak point in the fascia of the abdominal wall. Its sac is medial to the inferior epigastric artery. 
  • 13. Differences b/n indirect & direct inguinal hernias? Indirect inguinal hernia Direct inguinal hernia Hernia gate is deep inguinal ring Hernia gate is in Inguinal space Hernia sac is lateral to the spermatic cord or inferior epigastric vessel Hernia sac is medial to the spermatic cord or inferior epigastric vessel Shape: oval Shape: round It can be acquired or congenital It can Only be acquired
  • 14. 3 elements of hernia  Hernia gate  Hernia sac (3 parts; neck, body and fundus)  Hernia content
  • 15. Signs and symptoms?  swelling/protrusion  Weakness or pressure in the groin  Pain or discomfort in the groin, especially when bending over, coughing or lifting  Occasionally, pain and swelling around the testicles when the protruding intestine descends into the scrotum  Severe pain in strangulated hernia
  • 16. Physical examination of patient?  Examine the patient (inspection and palpation) both standing and lying positions  Place your finger on the swelling and instruct patient to cough or strain  positive symptom of "cough push“ is elicited in case of hernia
  • 17. Assessment of inguinal hernia (Symptom of the "cough push"
  • 18. what can be done to diagnose hernia?  Anamnesis (weight lifting, chronic cough or constipation, previous abdominal surgeries etc.)  physical examination. (Digital investigation of the hernia channel)  Sonography of the hernia pouch.  herniography with injection of X-ray agent into the peritoneum  Common blood analysis.  Bacteriological examinations  Common urine analysis. contrast
  • 19. Ultrasound of right inguinal hernia
  • 20. Differential diagnosis of inguinal hernia? DISEASE FINDINGS 1. Abscess of groin region Hyperemia of skin, fluctuation, intoxication syndrome, constant pain, leukocytosis, bacterieia 2. Femoral hernia Protrusion below inguinal canal 3. Undescended testes Empty scrotum, negative’’ cough push’’ symptom, ultrasound shows testes in abdomen 4. Varicocele Feeling of heaviness in the testicle Mild to Moderate pain Visible or palpable enlarged vein 5. Testicular torsion Acute onset, severe pain, testicle is positioned high than normal,
  • 21. . Left-sided varicocele
  • 22. How can diagnosis of hernia be formulated? Location  Type  Reducible vs. irreducible  Complication (s)  Dx: Indirect Right inguinal hernia, irreducible with strangulation
  • 23. What are the treatment options of inguinal hernia?  Treatment of a hernia depends on whether it is reducible or irreducible and possibly strangulated. ◦ Reducible hernia  Can be treated with surgery but does not have to be. ◦ Irreducible hernia  Urgent surgical treatment because of the risk of strangulation.  An attempt to push the hernia back can be made ◦ Strangulated hernia  Emergency operation
  • 24. What are the possible complications of hernia?  Incarcerated (irreducible hernia) Strangulated hernia Signs and symptoms of strangulated hernia:  Nausea, vomiting or both  Fever  Rapid heart rate  Sudden pain that quickly intensifies  A hernia bulge that turns red, purple or dark  Absent bowel sounds on auscultation 
  • 25. Herniotomy & Herniorrhaphy  Open method and  Laparoscopic method
  • 26. Anterior abdominal wall layers
  • 27. Preoperative care       History, physical findings, Lab. Works: blood test, grouping and crossmatching, urinalysis, ultrasound, etc. signed informed consent form anesthesiologist examination and recommendation NPO, urinary catheter if necessary correction of hemodynamics; IV access for fluids, drugs (sedatives, antibiotics etc.) Explanation of the procedure to patient and Reassurance
  • 28. Steps of Herniotomy           Skin incision (3-5cm) above and parallel to inguinal ligament, then subcutaneous tissue Ligation of superficial epigastric vein Opening of scarpa’s fascia Opening of external oblique aponeurosis (follow fiber direction and avoid nerve damage; ilioinguinal, genitofemoral, iliohypogastric nerves,) Identify inguinal ligament (poupart’s ligament) Isolate spermatic cord (using a Penrose drain for convenient retraction) Dissect the spermatic cord (using the index finger in a sweeping and medially encircling fashion) to the internal ring Identify and isolate hernia sac (peritoneum) Reposition hernia into abdominal cavity Close the defect
  • 29. Steps of Herniorrhaphy (Lichtenstein technique)          Identify the conjoint tendon (lateral rectus border) First suture on lateral rectus border (not on pubic tubercle) to the mesh and tie securely but not too tight Then over (not through) pubic tubercle Suture to lower part of inguinal ligament Proceed until just beyond the internal inguinal ring Create a new internal ring and attach upper part of mesh to inguinal ligament Size the mesh and secure upper part with single sutures Close external oblique aponeurosis, then scarpa’s fascia Suture skin, infiltrate local anesthetic and apply sterile dressing
  • 30. Video (Lichtenstein technique) .
  • 31. Herniorrhapy (Bassini Repair) tension method A technique in which the surgeon sutures the conjoined tendon to the inguinal ligament, which slides the patient’s own muscles together to cover the hole in the abdominal wall and repair the hernia.
  • 32. Conjoint tendon (falx inguinalis) Common tendon of insertion of the transversus and obliquus internus muscles into the crest and spine of the pubis and iliopectineal line
  • 33. Postoperative care Patient is discharged the same day of operation once anesthesia wears off, but some may need to stay in the hospital overnight.  Drugs: only analgesic is necessary  Diet: start with sips of water, if patient can take it then semi-liquid foods until he can tolerate solid foods  Wound dressing until removal of sutures 
  • 34. Possible complications after herniorrhapy chronic pain  ejaculation disorders  Hemorrhage  infection  adhesions  Impotency  Recurrent hernias 
  • 35. Prognosis? The outcome of this surgery is usually very good. In a few persons, the hernia returns.
