Sumario:Background and study aims  The efficacy of complete closure versus simple closure for perforations during endoscopic submucosal dissection (ESD) has never been evaluated. We evaluated the efficacy of complete closure and simple closure for perforations and muscular layer injuries incurred during ESD. Patients and methods  Thirty-four consecutive patients who underwent “complete closure” or “simple closure” for correction of perforations and muscular layer injuries during colorectal ESD were enrolled in this study. Complete closure was performed by the mucosa-submucosa clip closure method using only conventional endo-clips. For simple closure, endo-clips are placed just for perforation or muscular layer injury, while leaving any mucosal defects open. Results  Among the 15 patients in the complete closure group, eight developed perforations and seven developed muscular layer injuries. Among the 19 patients in the simple closure group, six developed perforations and 13 developed muscular layer injuries during the ESD procedure. There were no statistically significant differences between the two groups in inflammatory reactions, adverse events, or length of the hospital stay. Conclusion  Complete closure and simple closure for perforations and muscular layer injuries during ESD seem to have similar efficacy. While simple closure for a perforation during ESD seems sufficient, further study will be required to confirm our results.
