Study Notes

Hernia Definition and Anatomy

  • Hernia is a protrusion of an organ or tissue through a weakness in the abdominal wall, composed of a covering tissue, peritoneal sac, and contained viscera.
  • Can be acquired or congenital, involving a musculofascial defect.
  • Most common type occurs in the abdominal wall, specifically at weak sites like the inguinal canal, femoral ring, and umbilicus.

Types of Hernias

  • Direct and Indirect Hernias: Indirect hernias are the most common (50%), occurring laterally to the epigastric vessels, while direct hernias (25%) develop through Hesselbach’s triangle.
  • Reducible and Non-reducible: Reducible hernias can return to the abdominal cavity, while non-reducible hernias cannot.
  • Incarcerated and Strangulated Hernias: Incarcerated hernias are trapped, potentially leading to strangulation, a surgical emergency where blood supply is compromised.
  • Incisional and Umbilical Hernias: Incisional hernias occur at surgical sites, and umbilical hernias are often found in children or obese patients.

Signs and Symptoms

  • Symptoms might include nausea, abdominal pain, epigastric pain, vomiting, and intestinal obstruction.
  • Strangulated hernias present a medical emergency due to compromised blood supply.

Surgical Interventions

  • Herniorrhaphy is the surgical repair of a hernia, distinguishing between open, laparoscopic, and robotic techniques.
  • Mesh overlay (Lichtenstein Repair) provides support in inguinal canal, sutured with nonabsorbable sutures; mesh plug repairs offer a tension-free approach for direct and femoral hernias.

Surgical Anatomy

  • Important anatomical sites include supraumbilical, umbilical, infraumbilical, and various types of hernias (inguinal, femoral).
  • The transversalis fascia is crucial for inguinal hernia repair.

Perioperative Considerations

  • Assessment involves identifying hernia type and location while ensuring surgical safety.
  • Positioning is usually supine, and anesthesia types vary based on patient health (general, spinal, or regional).

Surgical Repair Techniques

  • Inguinal Hernias: Involves careful dissection to avoid nerves and vessels, with mesh overlay or mesh plug techniques for repair.
  • Ventral Hernias: Address defects in the linea alba, including umbilical and epigastric hernias.
  • Laparoscopic Approach: Offers less pain, smaller incisions, and quicker recovery.

Nursing Considerations

  • Employ atraumatic instruments for dissection, utilize Penrose drains to isolate cords in inguinal repairs, and common sutures include Surgipro/Prolene for mesh repairs.
