Summary

Complete closure and simple closure techniques for endoscopic submucosal dissection (ESD) perforations show similar efficacy. Simple closure may be sufficient for perforations during ESD, but further research is needed.

Area of Science:

  • Gastroenterology
  • Endoscopy
  • Surgical Innovation

Background:

  • Endoscopic submucosal dissection (ESD) can lead to iatrogenic perforations and muscular layer injuries.
  • Optimal management strategies for these complications, specifically closure techniques, require further investigation.

Purpose of the Study:

  • To evaluate and compare the efficacy of complete closure versus simple closure for managing perforations and muscular layer injuries during colorectal ESD.

Main Methods:

  • A comparative study involving 34 patients undergoing colorectal ESD with either complete closure or simple closure for iatrogenic injuries.
  • Complete closure involved mucosa-submucosa clip closure, while simple closure focused on the defect without addressing mucosal gaps.

Main Results:

  • No statistically significant differences were observed between complete and simple closure groups regarding inflammatory reactions, adverse events, or hospital stay duration.
  • Both methods demonstrated comparable outcomes in managing perforations and muscular layer injuries incurred during ESD.

Conclusions:

  • Complete closure and simple closure appear to be similarly effective for managing perforations and muscular layer injuries during ESD.
  • Simple closure alone may be adequate for addressing perforations during ESD, warranting further investigation to validate these findings.
