gastroscope

 [gas´tro-skōp]
an endoscope especially designed for passage into the stomach to permit examination of its interior. The gastroscope is a hollow, cylindrical tube fitted with special lenses and lights. The newer types of gastroscope are made of glass fiber (fiberscope) which is more flexible. Each glass fiber reflects light and creates a mirror effect, making it possible to “go around corners,” and facilitating visualization of the curvature of the stomach.

The proportion of patients with abnormal gastroscopies was calculated directly, with 95% confidence intervals (CI) calculated using the exact method instead of the normal approximation of the binomial distribution due to the small sample size.
Thirty-two gastroscopies were performed in only 21 (32%) of the patients.
Regardless, a family history of GC may be a valid criterion to prompt screening, if one is looking to restrict gastroscopies to a select group of patients.
It is reasonable to expect that the yield of screening gastroscopies would be low in LS, where the lifetime GC incidence is estimated at 1%-8% (4-6), based on the fact that gastroscopy is a poor screening tool in other hereditary syndromes, such as Hereditary Diffuse Gastric Cancer (HDGC), which confer a much higher GC risk.
In a retrospective study of 33 CDH-1 mutation carriers having undergone screening gastroscopies, 41% of chromoendoscopy-guided biopsies revealed signet-ring cell carcinoma (in 10 patients) in lesions that would have otherwise been missed by white-light endoscopy (17).
There is a potentially higher likelihood of abnormal gastroscopies in individuals with a family history of GC but this result remains uncertain.
