Questions and Answers

What best describes the difference between a reducible and a non-reducible hernia?

A reducible hernia occurs only in the inguinal canal, while a non-reducible hernia can occur anywhere.

A reducible hernia can be pushed back into the abdominal cavity, whereas a non-reducible hernia cannot. (correct)

A reducible hernia is always associated with intestinal obstruction, while a non-reducible hernia is not.

A reducible hernia is typically present at birth, while a non-reducible hernia develops later in life.

Which of the following hernias is most commonly found in females?

Femoral hernia (correct)

Direct inguinal hernia

Indirect inguinal hernia

Incisional hernia

What is indicated by a strangulated hernia?

The hernia is uncomplicated and can be managed outpatient.

The blood supply to the herniated tissue is compromised. (correct)

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.
