  What is ahernia?  A hernia is an abnormal weakness or hole in an anatomical structure which allows something inside to protrude through.  It is commonly used to describe a weakness in the abdominal wall.

  NOMENCLATURE Incomplete hernia  Bubonocele—limitedwithin the inguinal canal  Funicular—limited just above the epididymis Complete hernia  traverses to the bottom of the scrotum Littre”s hernia Richters hernia Irreducible hernia Obstructed Strangulated hernia Hernia of hydrocele Hydrocele of hernia

  Nyhus Classification  TypeI: Indirect inguinal hernia Internal inguinal ring normal (simple pediatric hernia)  Type II: Indirect inguinal hernia Internal inguinal ring dilated but posterior inguinal wall intact (inferior deep epigastric vessels not displaced)

  Nyhus Classification  TypeIII: Posterior wall defect  A. Direct inguinal hernia  B. Indirect inguinal hernia- internal inguinal ring dilated (massive scrotal or sliding hernia)  C. Femoral hernia  Type IV: Recurrent hernia  A. Direct  B. Indirect  C. Femoral  D. Combined

  Gilbert’s Classification Types 1,2 and 3 are indirect hernias; types 4 and 5 are direct.  Type 1 hernias with an intact internal ring that will not admit 1 fingerbreadth (<1 cm); the posterior wall is intact.  Type 2 hernias (the most common indirect hernia) have a peritoneal sac coming through a 1-fingerbreadth internal ring (≤2 cm.); the posterior wall is intact.  Type 3 hernias with 2-fingerbreadth or wider internal ring (>2 cm.)  Type 3 hernias begin to break down a portion of the posterior wall just medial to the internal ring. Often have a sliding component.  Type 4 hernias have a full floor posterior wall breakdown or multiple defects in the posterior wall. The internal ring is intact, and there is no peritoneal sac.  Type 5 hernias are pubic tubercle recurrence or primary diverticular hernias. No peritoneal sac and the internal ring remains intact. In cases where double hernias exist, both types are designated (ex. Types 2/4). Descriptors such as L, Sld., Inc., Strang. Fem. are used to designate lipoma, sliding component, incarceration, strangulation and femoral components.

  Gilbert’s Classification  In1993, Rutkow and Robbins added  type 6 to designate double inguinal hernias  type 7 to designate a femoral hernia.

  Pelvic & InguinalAnatomy Both the ilioinguinal nerve and the genitofemoral nerve traverse the usual hernia-repair operative field. The femoral vein also runs just deep to the inguinal floor laterally.

  Myopectineal Orifice ofFruchaud The MPO is bordered:  Above by the arching fibers of the internal oblique and transversus abdominus Muscles,  Medially (towards the center or to the right) by the Rectus Abdominus Muscle and its fascial Rectus Sheath  Inferiorly by Coopers Ligament, and  Laterally by the Ileopsoas Muscle  Running diagonally thru the MPO is the inguinal ligament

  Etiology of Hernias Congenital  Hydrocele vs. indirect hernia  Patency rate of processus vaginalis  60% at 2mo; 40% at 2yo; 20% in adults  Connective tissue abnomalities  Smoking (collagen metabolism)  Malnutrition, Vitamin deficiency  Increased intra-abdominal pressure  COPD, dialysis, ascites, BPH  Chronic constipation  Strenuous labor ?

  Composition of hernia 1.Sac:a folding of peritoneum consisting of a mouth, neck, body and fundus. 2.Body: which varies in size and is not necessarily occupied. 3.Coverings: derived from layers of the abdominal wall. 4.Contents: which could be anything from the omentum, intestines, ovary or urinary bladder.

  Symptoms 1…Swelling in inguinoscrotalregion Increasing on coughing,straining,walking Decreasing on lying down 2…h/o irreducibility 3…h/o obstruction pain, vomiting,obstipation distension of abdomen. 4…h/o Strangulation redness,shock,sepsis

  Clinical Diagnosis 1. Canyou get above it? 2. Reducibility test 3. Expansile Cough Impulse; 4. Invagination test 5. Three finger test Zieman’s technique 6. Ring occlusion test

• 25.
  1-Cough Impulse •Pt. coughsto highlight hernia. •May not ;if the neck is blocked by adhesions •Visible & Palpable cough impulse. •Reappear on straining, standing or coughing
• 26.
  2-Reducibility test  Askpt. to reduce hernia himselves  In lying position.  Thigh of the affected side should be flexed, adducted and internally rotated.  Finger guard of the inguinal canal by thumb and index finger and then the scrotum is gently squeezed.
• 27.
  3-Get above theswelling test • Done in standing position • At the root of the scrotum place the thumb in front and the index behind •Try to reach above the swelling. • Inguinal hernia; cannot get above • Pure scrotal swelling; will get above
• 28.
  4-Invagination test •The scrotumon each side is inverted with the examining index finger •Entering the inguinal canal along the course of the cord structures. •The size of the external ring. •The finger push up to the superf inguinal ring. •The pulp should feel the ring. •Pat is asked to cough, •A palpable impulse will confirm the hernia; felt on the pulp then direct felt on the tip then indirect hernia.
• 29.
  5-Three finger test/ Zieman’s technique Index finger; deep inguinal ring (indirect hernia) Middle finger; superficial ing. Ring (direct hernia) Ring finger; saphenous opening (femoral hernia) The patient is asked to cough.
• 30.
  6-Ring occlusion test •Reducethe hernia •Occlusion of the deep ring by thumb. •Then holding the thumb in position ask The pt to stand then cough •If no bulging; indirect •If bulging; direct .

  Lichtenstein Repair  Popularizedthe use of polypropylene mesh in primary hernia repairs  Mesh is laid over the undisturbed inguinal floor, posterior to the spermatic cord sutured to the shelving edge of the inguinal ligament, internal oblique fascia and the pubis
• 35.
  Bassini Repair  Isfrequently used for indirect inguinal hernias and small direct hernias  The conjoined tendon of the transversus abdominis and the internal oblique muscles is sutured to the inguinal ligament

  Shouldice Repair  AKA:Canadian Repair  A primary repair of the hernia defect with 4 overlapping layers of tissue.  Two continuous back-and-forth sutures of permanent suture material are employed. The closure can be under tension, leading to swelling and patient discomfort.

  When is laparoscopy appropriate? Recurrent hernias - avoid a previously operated field  Bilateral hernias - one set of incisions better than two inguinal incisions; one mesh to cover both overlay bladder
• 40.
  Types of LaparoscopicInguinal Hernia Repair  IPOM (IntraPeritoneal On-lay Mesh) repair. A mesh is placed intra- abdominally covering the hernia defect and then secured to the abdominal wall. Very popular at the beginning of laparoscopic experience, it has since been abandoned.  TAPP (Trans Abdominal Pre-Peritoneal) repair. With this technique, the pre-peritoneal space is accessed from the abdominal cavity and a mesh is then placed and secured. This is procedure of choice for recurrent inguinal hernias or in case of incarcerated bowel – visualized.  TEP (Totally ExtraPeritoneal) repair. The mesh is again placed in the retroperitoneal space, but in this case, the space is accesed without violating the abdominal cavity. This is probably the most physiological repair although technically more demanding. The procedure of choice for bilateral inguinal hernia repairs

  Laparoscopic techniques versus open techniquesfor inguinal hernia repair. There is no apparent difference in recurrence between laparoscopic and open mesh methods of hernia repair. The data suggests less persisting pain and numbness following laparoscopic repair Return to usual activities is faster. However, operation times are longer and there appears to be a higher risk of serious complication rate in respect of visceral (especially bladder) and vascular injuries Cochrane Database Syst Rev. 2003;(1):CD001785

  Dangers/Areas to beAvoided  Triangle of pain  Contains cutaneous nerves  neuralgia  Major arteries and spermatic vessels  Epigastric vessels  Specific example: tension on vas deferens
