P-OGC94 Outcomes of oesophagectomy post endoscopic mucosal resection

Background Within developed nations, oesophageal adenocarcinoma has the greatest incidence of any solid organ tumour with number escalating on a yearly basis. A recent expert review by the AGA suggests that high grade Barrett’s dysplasia and intramucosal adenocarcinoma are better treated endoscopically rather than oesophagectomy and that endoscopic management is a reasonable alternative to oesophagectomy for selected patients with low risk pT1b tumours.. Risk factors for nodal involvement and recurrence have been suggested by Lee et al (1). This study aims to review the pathological and clinical outcomes following oesophagectomy post EMR. Methods Results Conclusions Whilst some low risk patients had residual tumour at oesophagectomy, these findings were similar to Nelson et al 3; recurrent/recurrent local tumour could be potentially managed by repeat EMR. The absence of nodal metastasis in this small series is consistent with the AGA recommendation of EMR as a reasonable alternative to oesophagectomy for patients with selected low risk pT1b tumors.
