Anastomotic, gastrojejunal ulcer: accuracy of radiological diagnosis in surgically proven cases.

Abstract The main aim of this study was to assess the sensitivity of barium meal reporting in surgically proven gastrojejunal ulcers. Early radiologists considered the niche an infrequent finding, but it later became accepted as the most important radiological sign. Various ancillary signs are suggestive, especially those resulting from stenosis near the anastomosis. Summated statistics from the English literature show that the barium meal report in surgically proven cases was correct and positive in about 60 per cent. If suggestive reports are added, the proportion reaches about 80 per cent. For ulcers following partial gastrectomy, the percentage of “positives” was slightly higher than for those following gastro-enterostomy, but the difference was not statistically significant. The present series showed 26 “positives” (44·1 per cent) out of a total 59 cases, and 39 “positives” plus “suggestives” (66·1 per cent). The proportions of “positives” and of “positives” plus “suggestives” were somewhat higher in...
