Gastric outlet obstruction by polypoid tumors.

Abstract

In the aforementioned article, we presented the case of a patient with gastric outlet obstruction, which was an extraordinary clinical representation for gastric gastrointestinal stromal tumors (1). In this case, on performing esophagogastroduodenoscopy (EGD), a polypoid lesion with a thick and long stalk (originating from the fundus and prolapsing to the duodenum via the pylorus) causing gastric outlet obstruction was observed. In Figure 2, the thick stalk of the polypoid lesion (originating from the fundus and extending to the pylorus) was shown in the retroflexion position of EGD. As the head of the polypoid lesion could not be removed from the duodenum by endoscopic methods, this section could not be monitored endoscopically. The complete image of the polypoid lesion was obtained after its surgical resection (Figure 3). In light of the authors’ criticism, we presented an EGD view of this case in Figure 1 for better understanding. The thick stalk (belonging to the polypoid) in the pylorus shown the flat position of the EGD.
