Examination of the stomach after operation is one of the most difficult and often most puzzling procedures in roentgenology. In postoperative examinations the roentgenologist deals with an inconstant situation. The types of operation are many and varied, and the results of the same operation, especially if it is performed by different surgeons, may be different in appearance. The purpose of this article is to present the normal appearance after some of the more common operations on the stomach and to describe some lesions, particularly peptic ulcer and gastric neoplasm.
Most gastric operations are performed to remove diseased tissue, to decrease gastric acidity, and to reestablish continuity of the lumen. The many and varied operations devised to obtain these effects are usually performed for peptic ulceration and neoplasm. Since these two lesions are likely to recur, most roentgenologic examinations after operation are made to detect recurrent ulcers and neoplasm. Of the two processes recurrent benign ulceration is the more common. As these recurrent ulcers usually develop about the stoma of a gastroenterostomy, it is imperative that the roentgenologist be familiar with the different surgical procedures.
It is not my purpose to describe every operation for treatment of benign ulceration or neoplasm, for many operations are rarely used. The discussion is confined to a few popular types employed in the United States.
Many types of operation performed on the stomach may present similar appearances at roentgenologic examination. For instance, it is not always possible to tell whether at the time of a. . .
