High Joule heat during endoscopic submucosal dissection (ESD) significantly increases the risk of post-ESD electrocoagulation syndrome (PECS). Minimizing thermal damage is crucial for preventing this inflammatory complication.
Area of Science:
- Gastroenterology
- Endoscopic Surgery
- Surgical Complications
Background:
- Thermal damage to the mucosal surface during endoscopic submucosal dissection (ESD) can cause inflammation.
- Post-ESD electrocoagulation syndrome (PECS) is a potential complication following the procedure.
Purpose of the Study:
- To investigate the association between Joule heat exposure and the development of PECS.
- To identify factors contributing to PECS after colorectal ESD.
Main Methods:
- Prospective study of 202 patients undergoing colorectal ESD.
- PECS defined by fever and abdominal pain; high Joule heat defined as 15390 J.
- Exclusion of patients with intraoperative perforation or penetration.
Main Results:
- PECS occurred in 14.9% of patients.
- High Joule heat was an independent risk factor for PECS (OR = 7.96, P < 0.01).
- Procedure time and lesion location were not associated with PECS.
Conclusions:
- Accumulated thermal damage is a key factor in PECS development.
- Managing thermal exposure during ESD is important for preventing PECS.
