Abstract

Upper gastrointestinal subepithelial tumours (SETs) are generally asymptomatic and clinically insignificant and have malign, borderline and benign variants. In advanced endoscopic procedures, histopathological diagnosis and endoscopic resection are possible and feasible. In this study, we examined our approach to upper gastrointestinal subepithelial tumours and our clinical results. Adult patients who applied to Surgical Endoscopy unit between January 2014 and January 2015 were included in the study. The patients' files and final histopathological diagnoses were recorded and analysed retrospectively for this single-center study. SET lesion lower than 30 mm and the lesion whose endoscopic submucosal dissection attemption was included in the study. The total of 8 patients were four female (50%) and four male (50%), aged 31-66 years (median, 53 years). The tumoral lesions were located 4 (50%) patients in esophagus, 3 (37.5%) patients in stomach and one (12.5%) patient in duodenum and their diameter ranged from 5 to 30 mm (median, 14 mm). Post-interventional no complications or abdominal symptoms were encountered. Also, in early follow-ups for six months, no recurrence was observed. Our experiences together with literature reported here, indicated endoscopic resection is a safe and effective method of treatment for most patients with upper gastrointestinal SETs.

Highlights

We examined our approach to upper gastrointestinal subepithelial tumours and our clinical results
Submucosal masses or lesions often referred to as “submucosal tumours”, represent a growth underneath the mucosa of the gastrointestinal (GI) tract whose etiology cannot be determined by GI endoscopy or barium contrast studies (Geis et al, 1996)
One gastrointestinal stromal tumour (GIST) was in stomach, one lipoma was in distal esophagus and one gastrointestinal mesenchymal tumour was in bulbus duodeni

Summary

Introduction

Submucosal masses or lesions often referred to as “submucosal tumours”, represent a growth underneath the mucosa of the gastrointestinal (GI) tract whose etiology cannot be determined by GI endoscopy or barium contrast studies (Geis et al, 1996). It can be detected with oral contrast-enhanced abdominal computed tomography (CT). Other authors call these abnormalities subepithelial lesions, because they are covered by normal mucosa. These can be caused by external compression by the neighbouring organs or by intramural lesions. Submucosal is still recognized and used (Kojima et al, 1999; Sakamoto et al, 2010)
