CHRONIC ulcers that lie on the posterior gastric wall demonstrate some unique clinical and pathologic features that can be attributed to their anatomic location. This does not apply to craters that reach the lesser curve, although strangely, it includes those that extend to the greater curve.
The clinician has observed that the chronic posterior wall ulcer is encountered mainly in older patients. Summarizing some large series recorded in the literature, one finds that about 65% of all chronic posterior wall lesions of the pars media are first recognized after age 50, as compared with only 35% of chronic anterior wall pars media ulcers.

French and German radiologists and surgeons have emphasized on many occasions that more than the expected proportion of women is encountered among
