[Analysis of suggestive endoscopic characteristics in the preoperative diagnosis of gastric lymphoma].
We study the diagnostic value of some macroscopic features which might be considered suspicious of lymphoma (RESL): thickened gastric folds, diffuse involvement, shallow star shaped ulcers, net lesion limits, size > 6 cm., supracisural location and duodenal involvement. We analyze their overall incidence in 36 primary gastric lymphomas, considering possible differences of each feature between pre and post surgery diagnostic achievement. Preoperative diagnosis was related with the total number of RESL (p < 0.01). Diagnosis of lymphoma was highly suspicious when two or more of these features were present. Supracisural location (p = 0.0008) and shallow star shaped ulcers (p = 0.07) were the most significant RESL. Although RESL sensitivity has been low in the diagnosis of gastric lymphoma, we have found a high specificity for the presence of star shaped ulcers, diffuse involvement and duodenal involvement, which might be an aid in differential diagnosis.
