Hernia Types and Definition

Definition and Types

• A hernia is a protrusion or bulge that occurs when an organ or tissue pushes through a weakened area in the muscle or connective tissue that normally holds it in place.
• There are several types of hernias, including:
  • Inguinal hernia: occurs in the groin area, most common type
  • Umbilical hernia: occurs near the belly button
  • Hiatal hernia: occurs in the upper stomach
  • Incisional hernia: occurs through a previous surgical incision
  • Ventral hernia: occurs in the abdominal wall

Causes and Risk Factors

• Weakened muscles or connective tissue due to:
  • Age
  • Injury
  • Surgery
  • Obesity
  • Coughing or straining
  • Family history
• Increased pressure within the abdominal cavity due to:
  • Lifting heavy objects
  • Coughing or sneezing
  • Straining during bowel movements or urination

Symptoms

• A visible bulge or lump in the affected area
• Discomfort or pain in the affected area, especially with coughing, straining, or lifting
• Feeling of heaviness or pressure in the abdomen
• Discomfort or pain in the testicles (in the case of inguinal hernia)

Diagnosis and Treatment

• Diagnosis is typically made through a physical examination and medical history
• Imaging tests such as CT or MRI scans may be used to confirm the diagnosis
• Treatment usually involves surgery to repair the hernia, either:
  • Open hernia repair: a single incision is made to repair the hernia
  • Laparoscopic hernia repair: several small incisions are made and a laparoscope is used to guide the repair
  • Robotic hernia repair: a robotic system is used to assist with the repair

Complications

• Strangulation: the hernia becomes trapped and its blood supply is cut off, leading to tissue death
• Obstruction: the hernia blocks the intestine, leading to bowel obstruction
• Recurrence: the hernia returns after treatment, often due to inadequate repair or underlying risk factors
