Benign Lesions of the Upper GI Tract by Means of Endoscopic Ultrasonography

Laparoscopic Wedge Resection for Gastrointestinal Stromal Tumors of the Stomach: Initial Experience

“…Rapid innovations have been achieved in the diagnostic modalities for gastrointestinal tumors, and EUS has proven superior in diagnosing submucosal lesions of the stomach, allowing a clear view of the gastric wall and surrounding structures. 18,19 In addition, EUS-FNA through this device allows histopathological evaluation of submucosal lesions that are usually inaccessible by routine endoscopic biopsy. In the current series, 11 of the 12 specimens obtained by EUS-FNA were immunoreac- tive for c-kit, CD34, and SMA.…”

Laparoscopy in the management of gastric submucosal tumors

“…It also evaluated the depth of the tumor in five layers of the gastric wall. The ultrasonic imaging unit, Aloka SSD 680 (Aloka Co., Ltd., Tokyo, Japan), generated a real-time image with a 7.5-MHz convex array [16,32,36]. In Yamashita et al's series [42], the authors successfully identified a tumor site in the stomach in two patients, but this process requires an expensive laparoscopic ultrasonic system and some experience.…”

“…Additional diagnostic procedures were thought to be necessary in most patients. Endoscopic ultrasonography (EUS) allows good evaluation of the gastric wall and its surroundings [36] and has been shown to be superior in diagnosing submucosal lesions in the stomach [39]. Abdominal CT and repeat endoscopy are also valuable when the histopathologic results are not conclusive [16].…”
