Epigastric Hernia in Pediatric Age
Introduction to Epigastric Hernia in Pediatric Age
An epigastric hernia is a protrusion of abdominal contents through a weakness in the linea alba, the fibrous structure that runs down the midline of the abdomen. In pediatric patients, these hernias typically occur in the epigastric region, between the xiphoid process and the umbilicus. Epigastric hernias are relatively common in children, accounting for approximately 4-5% of all abdominal wall hernias in this age group.
Etiology of Pediatric Epigastric Hernias
The exact cause of epigastric hernias in children is not fully understood, but several factors contribute to their development:
- Congenital weakness: Most epigastric hernias in children are believed to be congenital, resulting from incomplete fusion of the anterior abdominal wall during fetal development.
- Increased intra-abdominal pressure: Conditions that increase abdominal pressure, such as chronic cough, constipation, or obesity, may exacerbate the development of epigastric hernias.
- Genetic factors: There may be a genetic predisposition to developing epigastric hernias, as they can run in families.
- Collagen disorders: Certain connective tissue disorders that affect collagen production may increase the risk of hernia formation.
Clinical Presentation of Epigastric Hernias in Children
The clinical presentation of epigastric hernias in pediatric patients can vary:
- Visible bulge: A small, round protrusion in the upper abdomen, typically along the midline between the breastbone and the navel.
- Intermittent appearance: The bulge may be more noticeable when the child cries, coughs, or strains.
- Pain or discomfort: Some children may experience mild pain or tenderness at the site of the hernia, especially when it protrudes.
- Asymptomatic: Many epigastric hernias in children are asymptomatic and discovered incidentally during routine physical examinations.
- Multiple hernias: In some cases, children may present with multiple small epigastric hernias along the midline.
Diagnosis of Pediatric Epigastric Hernias
Diagnosis of epigastric hernias in children primarily relies on clinical examination:
- Physical examination: The hernia is usually visible and palpable as a small, soft lump in the epigastric region. The physician may attempt to reduce the hernia by gently pushing it back into the abdominal cavity.
- Valsalva maneuver: The child may be asked to cough or strain to make the hernia more prominent if it's not immediately visible.
- Ultrasound: In some cases, particularly when the diagnosis is unclear, an ultrasound may be used to confirm the presence of a hernia and assess its contents.
- CT scan or MRI: These imaging modalities are rarely necessary but may be used in complex cases or when planning surgical repair of larger hernias.
Treatment of Epigastric Hernias in Pediatric Patients
The management of epigastric hernias in children depends on various factors:
- Observation: Small, asymptomatic hernias may be monitored for potential spontaneous closure, especially in very young children.
- Surgical repair: This is the definitive treatment for epigastric hernias and is generally recommended for:
- Symptomatic hernias causing pain or discomfort
- Large hernias
- Hernias that do not resolve spontaneously
- Incarcerated or strangulated hernias (rare but require immediate attention)
- Surgical techniques:
- Open repair: A small incision is made over the hernia, the protruding tissue is returned to the abdominal cavity, and the defect is closed with sutures.
- Laparoscopic repair: Less commonly used in children but may be considered for larger hernias or multiple defects.
- Timing of surgery: Elective repair is typically performed between 3-5 years of age, but may be done earlier if the hernia is symptomatic or large.
Complications of Pediatric Epigastric Hernias
While complications are rare, they can occur and may include:
- Incarceration: The hernia contents become trapped outside the abdominal cavity, leading to pain and potential tissue damage.
- Strangulation: Blood supply to the incarcerated tissue is compromised, resulting in tissue necrosis. This is a surgical emergency.
- Recurrence: There is a small risk of hernia recurrence after surgical repair, especially in children with underlying connective tissue disorders.
- Wound complications: As with any surgical procedure, there's a risk of infection or wound healing issues.
- Cosmetic concerns: Large hernias or multiple repairs may result in visible scarring.

- Question: What is the recommended treatment for symptomatic epigastric hernias in children? Answer: Surgical repair
- Question: What type of anesthesia is typically used for epigastric hernia repair in children? Answer: General anesthesia
- Question: What is the typical length of the incision for open epigastric hernia repair in children? Answer: 1-2 cm

- Question: What is the most common complication of epigastric hernia repair in children? Answer: Seroma formation
- Question: Can laparoscopic techniques be used for epigastric hernia repair in children? Answer: Yes, but open repair is more common due to the small size of most hernias
