Surgical diagnosis of gastric lesions

Methods for studying the stomach in transmitted light throughout the operation have been developed: reverse transillumination fibrogastroscopy, targeted forward and reverse transillumination angiography, and pigmentary injection transillumination angiography. The studies were carried out during the operation and on removed preparations. Of the 464 operated patients, 346 had stomach cancer, 45 had peptic ulcer disease, 43 had polyps, and 30 had non-epithelial tumors. Features of angioarchitectonics of the stomach are important for the recognition of initial lesions - erosions, ulcers, polyps.
