A hiatal hernia or hiatus hernia [2] is a type of hernia in which abdominal organs (typically the stomach) slip through the diaphragm into the middle compartment of the chest. [1] [3] This may result in gastroesophageal reflux disease (GERD) or laryngopharyngeal reflux (LPR) with symptoms such as a taste of acid in the back of the mouth or heartburn.
The diaphragm separates the chest from the abdomen. The esophagus (swallowing tube) passes through the hiatal opening in the diaphragm to reach the stomach. With a hiatal hernia, part of the stomach is displaced upwards into the chest (Figure 1). Large hiatal hernias may cause chronic gastrointestinal blood loss leading to iron deficiency anemia.
A hiatus hernia may be treated with lifestyle changes such as raising the head of the bed, weight loss and adjusting eating habits. [3] The medications H2 blockers or proton pump inhibitors may help. [3] If the symptoms do not improve with medications, a surgery known as laparoscopic Nissen fundoplication may be an option. [3]
Bochdalek hernia is one of two forms of a congenital diaphragmatic hernia, the other form being Morgagni hernia.A Bochdalek hernia is a congenital abnormality in which an opening exists in the infant's diaphragm, allowing normally intra-abdominal organs (particularly the stomach and intestines) to enter into the thoracic cavity.
It can be caused by or associated with gastroesophageal reflux disease, [1] esophagitis, a dysfunctional lower esophageal sphincter, disordered motility, lye ingestion, or a hiatal hernia. Strictures can form after esophageal surgery and other treatments such as laser therapy or photodynamic therapy. While the area heals, a scar forms, causing ...
A twist to this philosophic discussion on the art of diagnosis is that, in recent times, the possibility of an underlying pathophysiology has been considered—obesity is associated with gallstones, hiatal hernia, and diverticular disease, and there is the suggestion of an underlying connective tissue defect such as a "herniosis." [4]
Historically, mortality rates of 30–50% have been reported for acute gastric volvulus, with the major cause of death being gastric strangulation, which can lead to necrosis and perforation. With advances in diagnosis and management, the mortality rate from acute gastric volvulus is 15–20%, and that for chronic gastric volvulus is 0–13%.
Many different conditions can lead to the feeling of dyspnea (shortness of breath). DiagnosisPro, an online medical expert system, listed 497 in October 2010. [1] The most common cardiovascular causes are acute myocardial infarction and congestive heart failure while common pulmonary causes include: chronic obstructive pulmonary disease, asthma, pneumothorax, and pneumonia.
