Core Tip

Core tip: Although laparoscopic and endoscopic cooperative surgery (LECS) is a safer minimally invasive surgery that utilizes the advantages of both flexible endoscopy and laparoscopy, LECS invariably involves exposure to bacteria in the oral cavity because the flexible endoscope is passed through the oral cavity into the stomach. Nevertheless, there was no report how to disinfect the digestive tract more effectively. In this study, we established the systematic disinfection procedures of digestive tract lavage, endoscope disinfection and clean procedure of endoscopist and assistants in preparation for more minimal invasive flexible endoscopic surgery in near future.
