A surprise in the medical field: How to detect gastric torsion using imaging technology?
Gastric volvulus, or torsion of the stomach, is a pathological condition in which the stomach is fully or partially rotated more than 180 degrees. This can lead to impaired flow of gastric contents, altered blood supply, and possible tissue necrosis. Depending on the axis of rotation, gastric volvulus can be divided into organ axis type and mesenteric axis type. Understanding the diagnosis and treatment of this condition is particularly important for the medical community.
Types of Gastric VolvulusGastric torsion can cause severe abdominal pain, a nauseous feeling without the ability to vomit, and uncomfortable symptoms such as tinnitus.
In organ-axial gastric volvulus, the stomach rotates about the axis connecting the esophagus and pylorus. This is the most common form of gastric volvulus, accounting for about 59%. The mesenteric axis type refers to the rotation of the stomach along an axis that intersects the data of the few and many flexures, and this rotation is usually incomplete. Each type of imaging features is different and is associated with different clinical outcomes.
A complete diagnosis of gastric volvulus may require the use of imaging tests, especially photography and CT scans.
Causes of Gastric Torsion
The causes of gastric volvulus are generally divided into two types. The first type is gastric volvulus of unknown cause, accounting for about two-thirds of cases, which may be due to abnormal relaxation of the ligaments around the stomach; the second type is usually related to congenital or acquired anatomical abnormalities of the stomach.
How to diagnose gastric volvulus
The process of diagnosing gastric volvulus usually begins with a chest X-ray, and an abdominal X-ray can also help confirm the diagnosis. More specific tests include an upper gastrointestinal tract contrast study, which uses barium to show changes in the shape of the stomach.
CT scan is currently considered the preferred imaging tool for examining gastric volvulus and can provide a rapid and accurate diagnosis.
Advances in imaging have made diagnosis faster and can effectively rule out other abdominal lesions. Upper gastrointestinal endoscopy may reveal anatomical deformations of the stomach that are closely related to gastric volvulus.
Treatment methods for gastric volvulus
The main treatment for gastric volvulus is surgery, and early surgery significantly reduces the risk of complications. With the enhancement of diagnostic technology and improvement of surgical methods, the non-surgical mortality rate of gastric volvulus has been decreasing year by year.
The main cause of death is gastric strangulation, which leads to necrosis and perforation. Early medical intervention is crucial.
According to statistics, the mortality rate of acute gastric volvulus was as high as 30% to 50%, but in recent years, with the advancement of surgical technology, this figure has dropped to 15% to 20%. For patients with chronic gastric volvulus, the mortality rate is as low as 0% to 13%.
Conclusion
The diagnosis and timely treatment of gastric volvulus are crucial to the patient's survival prognosis. As medical imaging technology advances, more doctors are able to diagnose this condition quickly and accurately. In the future, can we find a way to prevent gastric torsion to reduce patient suffering and improve treatment outcomes?
