What is Organoaxial rotation of the stomach?
In an organoaxial gastric volvulus, the stomach rotates around an axis that connects the esophagogastric junction (EGJ) and the pylorus. The antrum rotates in the opposite direction to the fundus of the stomach.
What are the symptoms of a paraesophageal hiatal hernia?
Hiatal hernias and paraesophageal hernias may cause symptoms such as reflux and heartburn; nausea, burping, and vomiting; regurgitation of food; unexplained upper abdominal or chest pain; a sense of fullness after eating; bloating; shortness of breath or coughing; or a sense of food getting stuck in the chest.
What is intrathoracic stomach?
An intrathoracic stomach is the end stage of a hiatal hernial diaphragm and has a very low incidence. Frequently the diagnosis is made incidentally by endoscopic or radiographic investigations. There could be no clinical symptoms, however an intrathoracic stomach could be life treating.
What is it called when your stomach is twisted?
Gastric volvulus or volvulus of stomach is a twisting of all or part of the stomach by more than 180 degrees with obstruction of the flow of material through the stomach, variable loss of blood supply and possible tissue death.
What is the difference between a hiatal hernia and a sliding hiatal hernia?
In a hiatal hernia, the stomach bulges up into the chest through that opening. There are two main types of hiatal hernias: sliding and paraesophageal (next to the esophagus). In a sliding hiatal hernia, the stomach and the section of the esophagus that joins the stomach slide up into the chest through the hiatus.
What causes Organoaxial volvulus?
Organoaxial gastric volvulus results from the rotation of the stomach around the axis that bisects the lesser and greater curvatures of the stomach (table 1).
Can a hiatal hernia get twisted?
But if the hernia is a bit larger, it could force the opening in your diaphragm to become larger, too. At that point, the entire stomach and other organs are in danger of sliding up into your chest. A hiatal hernia can also put undue pressure on your stomach, by squeezing or twisting it.
How do you fix a twisted stomach?
A volvulus needs prompt treatment and usually requires surgery. During surgery to correct a volvulus, a doctor will make a small incision in the abdominal wall near the site of the twisted part of the intestine and untwist it. Afterward, the doctor will restore blood flow to the areas affected by the volvulus.
Can you see a hiatal hernia on a CT scan?
CT scanning is not routinely used in the diagnosis of a hiatal hernia, but it may be a useful for specific indications. Hiatal hernias often are seen incidentally on CT scans obtained for other indications (see the image below).
What kind of hernia is on the long axis?
In this case we see a compound hiatal hernia, which is a combination of sliding hiatus hernia and a rolling (para-esophageal) hiatus hernia. Organo-axial gastric volvulus is the more common gastric volvulus with the stomach rotated along its long axis.
Is there such a thing as a para esophageal hernia?
Para-esophageal hernia is a severe form of hiatal hernia that occurs in only 5% of cases. In this case we see a compound hiatal hernia, which is a combination of sliding hiatus hernia and a rolling (para-esophageal) hiatus hernia. Organo-axial gastric volvulus is the more common gastric volvulus with the stomach rotated along its long axis.
Can a hernial sac be resection for gastric volvulus?
Resection of the hernial sac and the role of gastropexy for preventing recurrence remain controversial. Advances in laparoscopic surgery have made possible a laparoscopic approach to most cases of chronic gastric volvulus.
