Abstract
An infrared endoscopic system has been developed to investigate thermal spread and collateral damage during energized laparoscopic surgery, the system consists of an infrared endoscope and a thermal camera (3-5 μm) with combined thermal sensitivity of 0.05°C. The system performance was evaluated in live animals with electrosurgical devices to monitor intraoperative thermal changes. During activation periods, the peak temperature of the jaws averaged 100.5 ± 5.8 ℃ with a thermal spread of 3.0 ± 0.9 mm. For laparoscopic dissections of the esophagus-gastric junction with the 10 mm Atlas, the maximum jaw temperature was 105.2 ± 2.1 ℃ with a bigger thermal spread of 11.5 ± 7.2 mm). The study has confirmed that infrared endoscopy is a very useful tool adjunct to conventional endoscopy, which may improve the safety of energized laparoscopic dissections.
