THE PURPOSE

Evaluation of flexible endoscopy in diagnostic and treatment of submucosal esophageal tumors.

MATERIAL AND METHODS

Endoscopic interventions in 25 patients (10 — men; 15 women) with submucosal tumors in 2018—2020 were performed. The duration of the age ranged from 30 to 72 years (mean 49 years). In 18 (72%) cases, the tumor was detected early. In 7 cases, the tumor was detected with additional examination in a hospital. There weren’t any complaints in 17 cases. 8 patients complained about dysphagia with solid food intake (7) and heartburn (1). The maximum size of tumors was 20 mm.on average.

RESULTS

Intraoperative EUS to clarify the localization of the tumor was performed in two cases. In cases of tumor localization in submucosal space (1) and mucosal muscle layer (8) endoscopy mucosal resection (2) and submucosal tumor dissection were performed. In all cases (14) for submucosal tumors originating from muscularis propria submucosal tunneling endoscopic resection was done. The duration of the intervention ranged from 15 to 125 minutes (on average 61.23 minutes). There weren’t complication during operation time and early time after procedure. The tumors were completely removed in all cases. There were no discrepancies between the localization of the tumor according to the ultrasound and intraoperative data. Pathomorphological examination of removed tumors in 24 patients was diagnosed with leiomyoma, in 1 case — granular cell tumor.

CONCLUSION

Endoscopic interventions for submucosal esophageal tumors are highly effective and safe. Endoscopic ultrasound examination, including using a mini probe is mandatory for visualizing the neoplasm, determining the true size and layer of the esophageal wall before the intervention planning. The tumor size is limiting for spread of endoscopic methods using.
