Roentgen Diagnosis of Linear Ulcers

Abstract

Linear peptic ulcerations are not uncommon lesions of the stomach and duodenum and can be demonstrated by upper gastrointestinal series. This is facilitated by the double contrast technique, but they may also be appreciated via compression methods. The criteria found helpful to establish the presence of a linear ulcer include: (a) contour deformity; (b) niche projection; (c) fuzzy line; and (d) folds radiating to a line (crater). Routine use of these criteria with the double-contrast method enabled the authors to diagnose 42 linear ulcers.

Radiographic findings of intractable gastric ulcers with H 2 -receptor antagonists

“…Long linear ulcers tend to be associated with a marked shortening and a deformity of the lesser curve, whereas shorter linear ulcers tend to be associated with less deformity [8][9][10]25]. A radiological diagnosis of linear ulcers may thus be made by the presence of either a characteristic deformity (a shortening of the lesser curvature and/or a U-shaped incisura at the lesser curvature side), a linear niche, or both, as was done in this study [11,12]. Either a pouchlike stomach or a snail-shaped stomach develops when a linear ulcer lies perpendicularly across the lesser curvature of the angle [8][9][10].…”

“…The diagnosis of a linear ulcer was made on either the direct or indirect demonstration of a linear ulcer. The direct features of a linear ulcer indicate the direct visualization of a linear niche, whereas the indirect features indicate a shortening of the lesser curvature of the antrum [8][9][10] and/or a Ushaped deformity of the lesser curvature, which indirectly shows the presence of linear ulcer [11,12].…”

Double-Contrast Upper Gastrointestinal Radiography: A Pattern Approach for Diseases of the Stomach

“…Some shallow ulcers on the dependent wall and ulcers on the nondependent wall may be manifested as a circular or hemispheric ring due to barium coating the rim of the unfilled ulcer crater (Fig 14) (56). Most ulcers are round or ovoid, but some may have a linear, serpentine, rectangular, flame-shaped, or rod-shaped configuration (56)(57)(58).…”
