Surgical Options In The Management Of Hernia Repair Surgical Options In The Management Of Hernia Repair Presentation Transcript

  • outlines  Definition  Epidemiology  Anatomy  Surgical management options
  • Hernia  A hernia is defined as an abnormal protrusion of an organ or tissue through a defect in its surrounding walls.  Groin hernia  Inguinal  Direct  Indirect  femoral
  • Epidemiology
  • Epidemiology
  • Predisposing factors
  • Epidemiology  Bimodal peak age : < 1 year then > 40 years  Right-sided groin hernias are more common than those on the left.
  • Types of hernia - Condition
  • Inguinal Canal Anatomy  No disease of the human body, belonging to the province of the surgeon, requires in its treatment a better combination of accurate, anatomical knowledge with surgical skill than Hernia in all its varieties. Sir Astley Cooper, 1804
  • Inguinal Canal Anatomy  The inguinal canal is an oblique space measuring 4 cm in length that lies above the medial half of the inguinal ligament.  Inguinal canal has 4 walls : anterior, posterior, roof, and floor
  • Important ligaments
  • Contents of the inguinal canal  Males : spermatic cord and ilioinguinal nerve  Females : round ligament and the ilioinguinal nerve
  • The spermatic cord  It consists of  Three coverings  Three arteries  Three other structures.  Nerves
  • The Spermatic Cord
  • Preperitoneal space  Space of Retzius  Space of Bogros  Inf. Epigastric  Vas deferens  the lateral femoral cutaneous nerve  the genitofemoral nerve.
  • Management  Uncomplicated hernias require either :  No treatment  Support with a truss  Operative treatment  complicated hernias :  always require surgery, often urgently.
  • Should we repair ? Inguinal hernia : should we repair ?
  • Inguinal hernia : should we repair ?
  • Surgical approaches  For any hernia the surgical option comprises 2 components :  Herniotomy  Herniorrhaphy or hernioplasty  It is either :  Open repair  Laparascopic repair
  • Surgery  Surgery aims to  Reduce the hernial contents  Excise the sac (herniotomy) in most cases  Repair and close the defect either by herniorrhaphy or hernioplasty
  • Components of the hernia
  • Hernial Sac Dissection
  • Types of open repair  Repairing the floor of the inguinal canal :  Bassinirepair  Shouldice repair  Tension free mesh repair
  • Bassini repair  The conjoined tendon is retracted upward  the aponeurosis of the transversus abdominis muscle is approximated to the iliopubic tract that lies adjacent to the inguinal ligament with several interrupted 3-0 silk sutures.  The second layer of the repair involves suturing the conjoined tendon to the inguinal ligament with interrupted 2-0 silk sutures.  This suture line extends from the pubic tubercle to the medial border of the internal ring.
  • Shouldice Repair  With a no. 15 scalpel an incision is made in the transversalis fascia. This incision is extended from the internal ring to the pubic tubercle.  The repair involves placing four lines of sutures.
  • Shouldice repair  The first suture line  is started at the pubic tubercle using 3-0 continuous polypropylene, and the white line is approximated to the free edge of the inferior transversalis fascial flap.  The 2nd suture line :  At the internal ring the suture is tied and then continued medially by approximating the free edge of the superior flap to the shelving edge of the inguinal ligament. When the pubic tubercle is reached, the suture is tied and divided.
  • Shouldice repair  The third suture line is started at the level of the internal ring where the conjoined tendon is approximated to the inguinal ligament and tied when the pubic tubercle is reached.  Using the same suture, the fourth suture line attaches these same structures to one another and is tied at the level of the internal ring.
  • Shouldice repair  The cord is replaced within the inguinal canal, and the external inguinal aponeurosis is reapproximated with continuous 2-0 absorbable sutures
  • Tension – free repair  There are several options for placement of mesh during anterior inguinal herniorrhaphy, including  The Lichtenstein approach  The plug-and-patch technique  The sandwich technique with both an anterior and preperitoneal piece of mesh.
  • Tension – free repair
  • Tension – free repair

  • Comparison of open approachs
  • Recurrence rate “ PGY “
  • Laparoscopic Repair
  • Indications for laparoscopic repair  Bilateral inguinal hernia  When the diagnosis of inguinal hernia is uncertain  When the patient want to return to normal physical life
  • Contraindications  The patient medical condition makes general anesthesia more risky  Patient who have planned pelvic or extraperitoneal operations (eg, radical prostatectomy)  Patient who have had a recurrence from a prior laparoscopic repair  Patient presented with strangulated hernia
  • Advantages of laparoscopic  Less acute postoperative pain  Shorter convalescence  Earlier return to work
  • Disadvantages  increased risk of femoral nerve injury and  Increased risk of spermatic cord damage  risk of developing intraperitoneal adhesions with the TAPP  greater cost and duration of the operation.
  • Laparoscopic Approaches  Laparoscopic repair is done by 2 approaches : 1. Transabdominal preperitoneal “TAPP” 2. Totally extraperitoneally “TEP”
  • Transabdominal Preperitoneal  The TAPP approach, first described by Arregui and colleagues in 1992  It requires laparoscopic access into the peritoneal cavity and placement of mesh in the preperitoneal space after reducing the hernia sac.
  • Totally extraperitoneally  The first TEP inguinal hernia repair was described by McKernan and Laws in1993.  This approach involves preperitoneal dissection and mesh placement without entering into the abdominal cavity.
