Differential diagnosis of gastric submucosal masses and external pressure lesions

Abstract

Lesions of the left triangular ligament of the liver are rare, and there are even fewer cases of vascular tumors misdiagnosed as gastrointestinal stromal tumors. We comment on the two cases reported in the article. The article did not include pictures of laparoscopic surgery, making it unconvincing. For gastric submucosal lesions, enhanced computed tomography venous phase imaging may be beneficial for differential diagnosis. Although endoscopic ultrasound is an effective tool for diagnosing submucosal lesions of the stomach, due to various factors, it cannot achieve an accurate diagnosis. During endoscopic examination, a more accurate diagnosis can be made depending on the personal experience of the operators.

Keywords: Differential diagnosis; Gastric submucosal masses; External pressure lesions; Endoscopic ultrasonography; Computed tomography

Core Tip: We have raised some issues regarding the two cases reported in the article. No figures of laparoscopic surgery are shown in the article, which lacks persuasiveness. For gastric submucosal lesions, the accuracy of enhanced computed tomography venous phase imaging combined with endoscopic ultrasound diagnosis is high. During endoscopic examination, a more accurate diagnosis can be made based on the characteristics of gastric submucosal lesions.
