Farzan F. Bahin et al. Comparison of the histopathological effects of two electrosurgical currents in an in vivo porcine model of esophageal endoscopic mucosal resection

This porcine survival study assessed the effect of electrocautery setting on tissue injury following 45 endoscopic mucosal resections in the esophagus in 12 pigs. Low power coagulation resulted in a quantifiably deeper depth of ulceration, necrosis, and acute inflammation compared with microprocessor-controlled blended current. The authors conclude that microprocessor-controlled blended current should be the preferred mode for esophageal mucosal resections.
