“Barrett’s esophagus

(BE) is a premalignant condition that results from the replacement of the normal squamous lining of the esophagus by a columnar epithelium containing intestinal metaplasia (IM) on biopsy. A 53-year-old man was followed at our institution for long-segment BE (Prague classification C1 M4) since 2007. His past medical history was unremarkable. There were no visible nodules

or ulcerations within the BE at endoscopy in 2007 and 2008. Biopsies, performed according to the Seattle protocol, were negative for dysplasia. The patient returned in 2011 for surveillance endoscopy. At this exam a flat, slightly elevated, lesion (Paris classification 0-IIa) with 8 mm of diameter was noted near the gastroesophageal junction (Fig. 1A). Targeted biopsies were compatible with intramucosal adenocarcinoma. Biopsy specimens of the remainder BE were negative for dysplasia. Endoscopic mucosal resection (EMR) was performed 5-FU with the patient under deep sedation with propofol. We used the Duette Multiband Mucosectomy Kit™ (Cook Medical, Limerick, Ireland), which consists Ribociclib cell line of a modified variceal band ligator that allows passage of a hexagonal 1.5 cm × 2.5 cm snare made of braided wire alongside the releasing wires for the bands. The area to be resected was previously delineated with coagulation markings (Fig. 1B). The lesion was first suctioned into the ligating barrel, and the rubber band was deployed creating

a pseudopolyp. Resection was carried out, in two fragments, with the ESG-100 electrosurgical unit (Olympus Europe, Hamburg, Germany), using pure coagulation current (Fig. 1C–F). There were no early or delayed complications. Specimens were pinned on cork and fixed in formalin. Pathologic examination revealed a moderately differentiated adenocarcinoma limited to the lamina propria (Fig. 2A–C). Lateral margins were not evaluable given the piecemeal technique. At 6-weeks follow-up endoscopy there were no signs of residual lesion (Fig. 3A). Biopsies of the resection scar and Barrett’s segment showed no dysplasia. Due to high risk of metachronous lesions ablation of the remaining BE was scheduled.
