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.
