Abstract:
Objective To evaluate the safety and efficacy of multi-band mucosectomy (MBM) for early esophageal cancer and precancerous lesions.Methods Data of 28 patients with early esophageal cancer or precancerous lesions undergoing MBM were reviewed in regarding of procedure complications and follow-up results.Results A total of 32 lesions were resected successfully by MBM in one session,with mean procedure time of 28.3 minutes.The mean diameter of specimens was 12mm.No residual neoplasm was found at the base of any resected specimens.The post-MBM pathological findings consisted of 2 cases of intramucosal cancer,1 case of submucosal cancer,and 25 cases of moderate-severe dysplasia.No perforation,delayed hemorrhage or subcutaneous emphysema occurred.Intraoperative bleeding occurred in 23 cases,including 3 cases of pulsatile bleeding,which were controlled with metal clip,and 20 cases of minor bleeding which were managed with APC or halted automatically at the end of procedure.Chest pain after the procedure occurred in 5 cases and were relieved soon.The patient with submucosal cancer underwent subsequent surgical resection,with no residual cancer in surgical specimen or lymph node metastasis.Twenty seven other cases were followed up endoscopically for 2-12 months.Esophageal stricture occurred in 2 cases,and were successfully relieved by dilatation with stent or bougienage.No recurrent lesion or metastasis were revealed.Conclusion MBM is a relatively safe and effective endoscopic technique for treatment of early esophageal intramucosal cancer and precancerous lesions,but further studies are needed to evaluate the long-term results.
