A paraesophageal hiatal hernia is the less common of the two types of hiatal hernia, which occurs when the upper part of the stomach pushes through an opening in the diaphragm, and up into the chest.

A little anatomy is needed to understand what is happening. A hernia means that an internal body part has been pushed into an area where it doesn't belong. Your torso is divided into the chest cavity where the lungs and heart are located and the abdomen where your stomach, intestines, and several other organs are located.

The chest cavity and abdomen are separated by a sheet of muscle, the diaphragm.The esophagus is the tube through which food and drink pass from the mouth to the stomach, and it travels through an opening in the diaphragm, the hiatus. Hence the name hiatal hernia. The esophagus shortens and lengthens during swallowing, and with a hernia, the stomach and/or the junction of the stomach and esophagus can get pulled through the hiatus.

There are two categories of hiatal hernias, sliding or paraesophageal. With paraesophageal hernias, the gastro-esophageal junction (where the esophagus attaches to the stomach) remains where it belongs, but part of the stomach is squeezed up into the chest beside the esophagus. The portion of the stomach that is on the wrong side of the hiatus remain in the chest at all times. With this type of hernia, complications can occur.

Complications of a Paraesophageal Hiatal Hernia

  • Incarceration: This is when the hernia is stuck and being squeezed. The portion of the stomach that is stuck in the chest cavity is being constricted.
  • Strangulation: This results from the blood supply to the stomach getting cut off. The tissues of the stomach can't live without a blood supply and so they die. This requires emergency surgery.
  • Stomach ulcer: If the stomach twists upon itself, it can develop a Cameron's erosion. As with other ulcers, it can lead to slow blood loss and anemia.

    The Symptoms of a Paraesophageal Hiatal Hernia

    Paraesophageal hernias often do not display any symptoms, but when symptoms are present, they are as follows:

    • Sudden severe chest pain
    • Radiating chest pain that isn't relieved by taking an antacid
    • Difficulty swallowing
    • Stomach pain
    • Indigestion
    • Nausea
    • Vomiting
    • Retching

    When Surgery is Needed for a Paraesophageal Hiatal Hernia

    • If the above symptoms are caused by a paraesophageal hiatal hernia that has become constricted or strangulated, then immediate surgical intervention is required.
    • If a hiatal hernia is in danger of becoming constricted or strangulated, surgery is often performed to reduce the hernia, putting it back where it belongs.

    What Type of Surgery is Done for a Paraesophageal Hiatal Hernia

    Hiatal hernia surgery is commonly done as a laparoscopic procedure. The laparoscope is a thin, telescope-like instrument with a camera on the end that enables the surgeon to view the inside of the abdomen. With this type of surgery, small incisions are made in the abdomen.

    The laparoscope and surgical instruments are inserted through these incisions. During the surgery, the stomach is repositioned, and the hiatus is reinforced.

    Many patients get a fundoplication, with the upper part of the stomach, the fundus, wrapped around the esophagus to reduce acid reflux.
