BackgroundEndoscopic submucosal dissection (ESD) is becoming widely regarded as a highly complicated but useful treatment for superficial esophageal neoplasms. However, the technique tends to be associated with adverse events. To evaluate the safety and utility of two-point fixed ESD for superficial esophageal neoplasms, and to discuss future directions.MethodsBetween December 2006 and December 2013, we performed two types of ESD procedures, the two-point fixed ESD that uses continuous countertraction to ensure a sufficient operative field was performed in 107 patients and conventional ESD was performed in 80 patients. Short-term outcomes and adverse events were evaluated. This study was retrospective study from a single institution.ResultsSignificant differences were observed between conventional ESD and the two-point fixed ESD with regard to the operation time, tumor positive and unknown vertical margins of the resected specimen, perforation as an adverse event, mediastinal emphysema, and postoperative stenosis.ConclusionThe two-point fixed ESD is a very useful method compared with the conventional procedure. |
