MARGINAL ulcer is a troublesome delayed complication following gastrectomy which is frequently difficult to demonstrate radiologically with certainty. Gastroscopy is a useful diagnostic adjunct,1 but even direct stomal visualization has limitations, because the ulcers are often shallow and difficult to differentiate from mucus plaques. Gastrocamera photography, on the other hand, provides multiple pictures which may be studied at leisure, as well as sufficient flexibility of the instrument to permit photographing not only the stoma itself, but also the jejunum beyond the anastomosis.
Gastrocamera photography has been used at the University of Wisconsin for more than three years, and the technique, as well as some of the results, have been previously reported.2,3 To date, 1,576 examinations have been performed, including 103 studies in patients who have had a previous gastrectomy. Normal gastrojejunostomy stomas are shown in color Fig 1 and 2.
Our purpose is to review those patients in
