Surgical Anatomy Of Anterior
            Abdominal Wall
n   Fascias
n   Rectus Sheath
n   Abdominal Muscles
n   Inguinal Canal
Inguinal Canal
n   Boundaries & Contents                  n   External ring is a triangular
    n   Anteriorly-External oblique            aperture in the aponeurosis
        aponeurosis &internal oblique          of the external oblique.It is
        laterally                              1.25 cms above the pubic
    n   Posteriorly-Transversalis fascia       tubercle.
        and conjoined tendon
    n   Superiorly-Conjoined tendon        n   Deep ring is a U shaped
    n   Inferiorly-Inguinal ligament           opening in the transversalis
    n   Contents
                                               fascia.It lies 1.25 cms above
         n   In males-spermatic cord and       the mid inguinal point.
             Ilioinguinl nerne.
         n   In Females-round ligament
             and Ilioinguinal nerve
Natural Mechanisms Preventing
                Hernia
n   Obliquity of the canal
n   Internal oblique muscle opposite the deep ring
n   Shutter action of the arched fibres of internal
    oblique and transversus abdominis
n   Plugging action of the spermatic cord due to
    contraction of the cremaster muscle
n   Sliding valve action of the U shaped internal ring
Definition of Hernia
n   Hernia is defined as an
    abnormal protrusion of
    viscus or part of viscus
    through a normal or
    abnormal opening in the wall
    of the cavity containing it.
n   Classification depending on
    the anatomical site of the
    hernia. (Inguinal, femoral,
    epigastric etc.)
n   Incidence: Inguinal-
    73%,Femoral-
    17%&Umbilical-8.5%)
Pathology
n   Composition                    n   Contents
    n   Sac- Diverticulum of           n   Intestine-enterocele
        peritoneum and consists        n   Omentum-omentocele or
        of mouth, neck, body and           epiplocele
        fundus. The diameter of        n   Meckel’s diverticulum-
        the neck determines the            Littre’s hernia
        outcome.
                                       n   Circumference of bowel-
    n   Coverings well                     Richter’s hernia
        amalgamated hence
        indistinguishable.             n   W loop of intestine-
                                           Maydl’s hernia

Hernia: An anatomical curse!

  • 1. HERNIA by Dr. Ketan Vagholkar. MS, DNB, MRCS, FACS Professor of Surgery & Consultant Surgeon
  • 2. Surgical Anatomy Of Anterior Abdominal Wall n Fascias n Rectus Sheath n Abdominal Muscles n Inguinal Canal
  • 3. Inguinal Canal n Boundaries & Contents n External ring is a triangular n Anteriorly-External oblique aperture in the aponeurosis aponeurosis &internal oblique of the external oblique.It is laterally 1.25 cms above the pubic n Posteriorly-Transversalis fascia tubercle. and conjoined tendon n Superiorly-Conjoined tendon n Deep ring is a U shaped n Inferiorly-Inguinal ligament opening in the transversalis n Contents fascia.It lies 1.25 cms above n In males-spermatic cord and the mid inguinal point. Ilioinguinl nerne. n In Females-round ligament and Ilioinguinal nerve
  • 4. Natural Mechanisms Preventing Hernia n Obliquity of the canal n Internal oblique muscle opposite the deep ring n Shutter action of the arched fibres of internal oblique and transversus abdominis n Plugging action of the spermatic cord due to contraction of the cremaster muscle n Sliding valve action of the U shaped internal ring
  • 5. Definition of Hernia n Hernia is defined as an abnormal protrusion of viscus or part of viscus through a normal or abnormal opening in the wall of the cavity containing it. n Classification depending on the anatomical site of the hernia. (Inguinal, femoral, epigastric etc.) n Incidence: Inguinal- 73%,Femoral- 17%&Umbilical-8.5%)
  • 6. Pathology n Composition n Contents n Sac- Diverticulum of n Intestine-enterocele peritoneum and consists n Omentum-omentocele or of mouth, neck, body and epiplocele fundus. The diameter of n Meckel’s diverticulum- the neck determines the Littre’s hernia outcome. n Circumference of bowel- n Coverings well Richter’s hernia amalgamated hence indistinguishable. n W loop of intestine- Maydl’s hernia
  • 7. Natural history n Reducible n Irreducible n Obstructed n Strangulated n Inflammed
  • 8. Clinical features of inguinal hernias
  • 13. Clinical Evaluation n History n Chief complaints (odp) n Complications n Etiology n Treatment taken n Inference from history
  • 14. Clinical Evaluation n Physical examination. n Inspection-site,impulse n Palpation- n Getting above n Impulse on coughing n Reducibility-Taxis n Deep ring occlusion test n Invagination test n Tone-Inspection/palpation n Other systems
  • 15. Clinical Diagnosis n Site, side, complicated or not, direct or indirect inguinal hernia n Status of tone n Possible etiological factor
  • 16. Investigations n Haematological n CBC n Blood sugar (fasting & postprandial) n BUN, creatinine, Electrolytes n Urine examination n Ultrasound of Abd. n ECG n CXR
  • 17. Principles of repair n Herniotomy for an indirect sac n Identify n Dissect n Open n Reduce the contents n Transect n Twist, tansfix, ligate & excise the redundant portion n Slit open the distal sac
  • 18. Principles of repair n Herniotomy for direct sac n Identify n Dissect around the neck n Purse string suture n Invert the sac and tighten the purse string n Direct sac never to be opened
  • 19. Principles of repair n Special cases n Pantaloon hernia n Sliding hernia n Strangulated hernia
  • 20. Principles of repair n Herniorrhaphy n Selection of patients n Principles (anatomic considerations) n Types n Bassini’s n Shouldice n Lichtenstein Repair(T abd to Ing Lig with relaxing incision& Ext obl behind the cord) n Other types (Ogilvie’s, Lyttle’s ,skeletonization of cord etc.)
  • 21. Principles of repair n Hernioplasty (Open approach) n Patient selection n Types n Mesh plasty n Darning n Material used n Endogenous n Exogenous n Requirements of a mesh
  • 25. Surgical Aftercare n Avoid straining n Avoid heavy work n Bowel function n Urinary system n Care to be taken for at least 3 months after surgery
  • 26. Complications n Intraoperative n Post operative n Infection n Neurological complications n Recurrence n Types n True n False
