Study Notes
Types of Hernias
- Direct Hernia: Occurs within Hesselbach’s triangle; associated with acquired weakness in the abdominal wall; does not affect the scrotum.
- Indirect Hernia: Most common, protrudes through the deep inguinal ring; occurs laterally to epigastric vessels; can affect the spermatic cord in males.
- Reducible Hernia: Can be manually reduced; not trapped.
- Non-reducible Hernia: Cannot be returned to abdominal cavity.
- Incarcerated Hernia: Trapped in the extra-abdominal sac, may lead to obstruction.
- Strangulated Hernia: Blood supply compromised; requires emergency intervention.
- Incisional Hernia: Occurs at a previous surgical site.
- Umbilical Hernia: Fascial defect under the umbilicus; common in children and obese patients.
Hernia Basics
- Defined as a sac containing organ or tissue protruding through a weakness in the abdominal wall.
- Composed of covering tissue and a peritoneal sac.
- May be congenital or acquired due to musculofascial defects.
- Most occur in the abdominal wall; common sites include inguinal canal, femoral ring, and umbilicus.
Hernia Repair and Surgical Anatomy
- Hernia repair is known as “Herniorrhaphy.”
- Signs of hernias include bulging at the site and symptoms of intestinal obstruction.
- Surgical options vary: open surgery, laparoscopic, and robotic techniques.
- Mesh use is common for strength and integrity restoration.
Surgical Procedures
- Native Tissue Repair: Local tissues utilized; involves identifying key nerves (iliohypogastric and ilioinguinal).
- Mesh Overlay (Lichtenstein Repair): Uses a single sheet of mesh for support; sutured to the internal oblique aponeurosis.
- Mesh Plug Repair: Tension-free approach with a cone-shaped plug; less tissue dissection and fewer sutures needed.
Hernia Types and Specifics
- Inguinal Hernia: Transversalis fascia is crucial; repair goal is to strengthen posterior floor.
- Femoral Hernia: Most common in females; occurs in the femoral canal; high risk of strangulation.
- Abdominal Hernias: Include umbilical and epigastric, typically arising from muscle weakness; umbilical hernia is particularly susceptible to incarceration.
Laparoscopic Repair Advantages
- Minimally invasive: smaller incisions, reduced pain, quicker recovery, and fewer recurrence rates.
Perioperative Nursing Considerations
- Assess type and location of hernia; ensure correct surgical site marking.
- Position patients supine for surgery; anesthesia options include general or spinal, depending on patient health.
- Instruments used include atraumatic techniques and specific sutures (Surgipro/Prolene) for mesh repairs.
Hernia Facts
- 50% of hernias are indirect (predominantly in males); 25% direct; 10% incisional; 3% femoral (most common in females).
Symptoms and Emergencies
- Incarcerated hernia symptoms: vomiting, intestinal obstruction, abdominal distention.
- Strangulated hernia is an emergency; prompt surgical intervention is critical.
