Transgastric endoscopic peritoneoscopy does not require decontamination of the stomach in humans

Introduction Natural orifice translumenal endoscopic surgery (NOTES) is a rapidly evolving field that provides endoscopic access to the peritoneum via a natural orifice. One important requirement of this technique is the need to minimize the risk of clinically significant peritoneal contamination. We report the bacterial load and contamination of the peritoneal cavity in ten patients who underwent diagnostic transgastric endoscopic peritoneoscopy.
