Supplementary Material for: Hybrid laparo-endoscopic resection of submucosal cardial tumors assisted by flexible articulated instruments

We report a new surgical method in 10 patients that underwent hybrid laparo-endoscopic resection (HLER) of submucosal tumors with the combination of flexible articulated laparoscopic instruments (FALI). We have assessed technical reproducibility, safety and morbidity. Resection was completed in all cases. Mean surgical time was 60 minutes (30-85). Median tumor size was 16 mm (12-30). The more frequent location was gastroesophageal junction. No complications were observed during the procedure. Length of stay was 1 day in all cases. We have found HLER to be a safe procedure allowing margin resection and organ preservation. The addition of FALI added ease of performance in hard-to-reach tumor locations.
