thermal injury
Unintended tissue damage from heat generated by electrosurgical instruments during laparoscopy.
Full Definition
Accidental tissue burns occurring during laparoscopic surgery from electrocautery devices, ultrasonic scalpels, or other energy-based instruments. These injuries can result from direct contact, electrical arcing, or heat conduction through tissue. Thermal injuries may affect organs adjacent to the target tissue and can occur outside the surgeon's direct visualization. Prevention strategies include proper instrument selection, appropriate power settings, and careful technique when working near critical structures like bowel, bladder, or major vessels.
Usage
Usage note: Distinguish from thermal spread, which refers to the expected zone of tissue heating around the target area.
In Context
- "The patient experienced delayed bowel perforation due to an unrecognized thermal injury during adhesiolysis." — complication report
- "Careful inspection revealed no evidence of thermal injury to adjacent structures." — operative report
