HERNIA EXAMINATION
Definition
- Hernia is a protrusion of an organ or part of an organ through a weakened or congenitally defective area in the abdominal wall.
Types
1. Inguinal Hernia
- Inguinal hernias occur in the groin area, where the abdominal wall is weakened.
- Direct inguinal hernias occur through Hesselbach's triangle (a weak area in the posterior wall of the inguinal canal), while indirect inguinal hernias occur through the deep inguinal ring.
- Indirect inguinal hernias are more common in men.
2. Femoral Hernia
- Femoral hernias occur below the inguinal ligament, near the femoral canal.
- Femoral hernias are more common in women and are associated with a higher risk of strangulation.
3. Umbilical Hernia
- Umbilical hernias occur around the belly button (navel) and are more common in infants and children.
- Umbilical hernias are often small and may resolve on their own, but can also be surgically repaired.
4. Incisional Hernia
- Incisional hernias occur through a scar in the abdominal wall from previous surgery.
- Incisional hernias can be small or large and may require surgical repair.
5. Diaphragmatic Hernia
- Diaphragmatic hernias occur through a weakness in the diaphragm, the muscle that separates the chest and abdominal cavities.
- Diaphragmatic hernias can be congenital or acquired and may be associated with respiratory problems.
Causes
- Weakening of the abdominal wall due to age, genetic factors, or previous surgery.
- Increased abdominal pressure due to obesity, straining during bowel movements, or heavy lifting.
- Congenital defects in the abdominal wall.
Clinical Features
- A bulge or lump in the abdominal wall, which may be painful or tender.
- A feeling of discomfort or pressure in the abdomen.
- Straining during bowel movements or heavy lifting may exacerbate the symptoms.
- In advanced cases, the hernia may become incarcerated or strangulated, leading to severe pain, vomiting, and potentially life-threatening complications.
Investigations
- Physical examination: A thorough physical examination, including a digital rectal examination, to assess the size and location of the hernia.
- Imaging studies: X-rays, CT scans, or ultrasound to confirm the diagnosis and rule out other conditions.
- Laboratory tests: Blood work to evaluate liver and kidney function, as well as to rule out other underlying conditions.
Complications
- Incarceration: The hernia becomes trapped and cannot be reduced.
- Strangulation: The blood supply to the herniated tissue is cut off, leading to tissue death and potentially life-threatening complications.
- Adhesions: Fibrotic bands may form between the hernia and surrounding tissues, making it difficult to repair.
Management and Treatment
- Observation: Small, asymptomatic hernias may be monitored without surgical intervention.
- Surgical repair: Hernias that are symptomatic, incarcerated, or strangulated require surgical repair.
- Laparoscopic repair: A minimally invasive surgical technique using small incisions and a camera to visualize the abdominal cavity.
- Open repair: A traditional surgical technique using a larger incision to access the hernia.
Surgical Steps
1 โ Incision: A small incision is made in the abdominal wall to access the hernia. 2 โ Dissection: The surrounding tissues are gently separated to expose the hernia. 3 โ Reduction: The herniated tissue is carefully reduced back into the abdominal cavity. 4 โ Repair: The weakened area in the abdominal wall is repaired using sutures or mesh. 5 โ Closure: The incision is closed, and the patient is monitored for complications.
Blood Supply and Nerve Supply
- Blood supply: The abdominal wall receives blood from the superior and inferior epigastric arteries.
- Nerve supply: The abdominal wall is innervated by the anterior branches of the intercostal nerves and the iliohypogastric nerve.
Clinical Anatomy
- The abdominal wall is composed of layers of muscle and fascia.
- The rectus abdominis muscle runs vertically in the midline of the abdomen, divided by the linea alba.
- The inguinal canal is a narrow passage in the abdominal wall that allows for the passage of the spermatic cord in males and the round ligament in females.
