What does Organoaxial mean?

What does Organoaxial mean?

In type 1, or organoaxial rotation, the stomach rotates around the pylorus-cardia axis. This is the most common type, comprising approximately 60% of cases, and may lead to obstruction at the gastroesophageal junction, the pylorus, or both—or even strangulation and vascular compromise.

How is gastric volvulus diagnosis?

The most common cause of gastric volvulus is hiatal hernia, but the principal predisposing factor is ligamentous laxity. The diagnosis is suspected when erect chest radiograph images show a high air-fluid level in the chest. Moreover a barium swallow is essential to confirm the diagnosis.

What causes acute gastric volvulus?

The most common causes of gastric volvulus in adults are diaphragmatic defects (see Table 2 below). In cases of paraesophageal hernias, the EGJ remains in the abdomen, whereas the stomach ascends adjacent to the esophagus, resulting in an upside-down stomach.

What is gastric strangulation?

Gastric strangulation is a complication that can occur after the development of acute gastric volvulus. Timely diagnosis and treatment of acute gastric volvulus can potentially decrease morbidity and mortality. Patients can simply present with mild abdominal pain associated with nausea and vomiting, without emesis.

How is gastric volvulus treated?

With chronic gastric volvulus, surgery is performed to prevent complications. The principles associated with the treatment of gastric volvulus include decompression, reduction, and prevention of recurrence, which are best accomplished with surgical therapy.

What causes gastric dilatation volvulus in dogs?

The exact cause of GDV is still unknown. The condition is seen more commonly in large, deep-chested male dogs. Exercise after ingestion of large meals or large amounts of water may increase risk. “Stress may be a contributing factor to GDV…”

Is gastric volvulus painful?

Clinical Manifestations and Diagnosis The presentation of acute gastric volvulus includes sudden severe pain in the upper abdomen or lower chest and persistent but unproductive vomiting. Because the volvulus causes gastric obstruction, it is often impossible to pass a nasogastric tube into the stomach.

What are the symptoms of gastric volvulus?

GASTRIC VOLVULUS The presenting symptoms can be intermittent or complete gastric obstruction, ischemia, pain, and/or bleeding. The most common signs and symptoms of gastric volvulus in children include acute abdominal pain, intractable retching, and the inability to pass a nasogastric tube into the stomach lumen.

Can you live with gastric volvulus?

In a study of 138 patients with hiatal hernia, 10 of the 21 patients who had gastric volvulus required emergency surgery; mortality was 40%, and the incidence of major morbidity was also 40%.

How serious is a twisted stomach?

The twisting causes bowel obstructions that may cut off the blood supply to areas of the bowels. A volvulus is a medical emergency that needs surgical treatment. If left untreated, the parts of the bowels that are not receiving enough blood will start to die.

How is gastric dilatation volvulus treated in dogs?

The treatment of this condition involves stabilization of your pet, decompression of the stomach, and surgery to return the stomach to the normal position permanently (gastropexy). Abdominal organs will need to be evaluated for damage and treated appropriately as determined at the time of surgery.

What is organoaxial volvulus?

Organoaxial volvulus occurs when the stomach rotates 180 degrees around the long axis. A diaphragmatic hernia is frequently associated with this condition. Symptoms are typically acute in onset, and gastric ischemia is a potential complication.

What is gastric volvulus and what causes it?

Gastric volvulus is a rare condition in which the stomach twists on itself, causing a closed-loop obstruction. There are two types, organoaxial and mesenteroaxial. Organoaxial volvulus is the more common type, representing approximately 60 percent of cases. Organoaxial volvulus occurs when the stomach rotates 180 degrees around the long axis.

What are the two types of volvulus?

There are two types, organoaxial and mesenteroaxial. Organoaxial volvulus is the more common type, representing approximately 60 percent of cases. Organoaxial volvulus occurs when the stomach rotates 180 degrees around the long axis. A diaphragmatic hernia is frequently associated with this condition.

Does gastric hernial sac resection prevent recurrence of 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.
