A hernia is a protrusion of part of an organ through the muscle wall that surrounds it. A hiatal hernia occurs when the upper part of the stomach pushes up into the chest through a small opening (called the hiatus) in the diaphragm, the muscle that separates the abdomen from the chest.
Most of the time, a hiatal hernia is small enough not to cause any symptoms and you may never know you have one. However, if your hiatal hernia is large enough, the opening in the diaphragm increases, allowing more of your stomach and sometimes other organs to slide into your chest. Sometimes, the hernia squeezes your stomach, causing restriction and discomfort. The stomach may rotate and twist as well. This results in retention of acid, which can easily back up into your esophagus, causing gastroesophageal reflux disease (GERD), heartburn, chest pain, swallowing problems, and breathing problems.
It is important that you choose an experienced medical team to treat your hernia. The Division of Thoracic Surgery at Brigham and Women’s Hospital (BWH) uses the most current diagnostic methods and offers proven treatments for patients with hernias, including minimally invasive laparoscopic surgical techniques aided by video technology.
Hernias are referred to by various names including hiatal hernia, paraesophageal hernia and the most rare, diaphragmatic hernia.
Hernias are also categorized by their size and configuration. The vast majority are called Type I, or sliding hiatal hernias. In this type of hernia, the stomach intermittently slides up into the chest through a small opening in the diaphragm.
Types II, III, and IV hernias are called paraesophageal hernias, which happen when a portion of the stomach pushes up into the chest adjacent to the esophagus. These hernias are much less common, but more concerning, because the blood supply to the stomach can be threatened and symptoms tend to be more severe.
The cause of hernias is unknown. Men and women of all ages can develop a hernia, but possible triggers include the following:
More severe symptoms are usually associated with a paraesophageal hernia. Those signs and symptoms include:
Patients with paraesophageal hernias may have a significant portion of their stomach or other abdominal organs push up into their chest. In severe cases, the stomach or abdominal organs may rotate or twist, causing severe pain. This is a medical emergency and will likely require immediate surgery.
You will receive a thorough diagnostic evaluation and receive clinically proven treatment by a board-certified thoracic surgeon who specializes in hiatal hernias. Careful monitoring and the involvement of an experienced thoracic surgeon is important to the successful outcome for patients with hernias.
If you need surgery, you will be taken care of in the operating room by surgeons, anesthesiologists and nurses who specialize in surgery for patients with thoracic problems. After surgery you will go to the recovery room (Post Anesthesia Care Unit) and then you will be transferred to the Thoracic Intermediate Care Unit (TICU) where you will receive specialized comprehensive care by an experienced medical and nursing staff to get you better rapidly.
