Natural orifice transluminal endoscopic surgery (NOTES): assessment of peritoneal bacterial load after intraperitoneal antimicrobial wash and evaluation of hemodynamic changes in a porcine model.
AIMS: Natural orifice transluminal endoscopic surgery (NOTES) is a promising newly developed procedure; however, it is associated with many complications. The main aim of our study is to assess whether peritoneal wash with antibiotics decreases the bacterial load contamination related to the transgastric approach. METHODS: Ten female farm pigs underwent transgastric peritoneoscopy with fallopian tubal ligation. Five pigs were randomized to antibiotic wash of the peritoneal cavity and five to placebo. All animals were given one intravenous dose of antibiotic before the procedure. Hemodynamic variables were continuously monitored throughout the procedure. The next day, peritoneal cultures were taken. The fallopian tubes were inspected to determine the success of ligation and the gastric incision sites were assessed for leakage. RESULTS: No significant difference was noted between the antibiotic peritoneal wash group and the placebo group in terms of peritoneal bacterial load with respective median colony-forming units per ml (CFU/ml) of 0 [0; 1] vs. 0 [0; 4], p = 0.637. No clinically significant hemodynamic changes were noted during the procedure. CONCLUSIONS: The results of our study indicate that NOTES carries minimal risk of peritoneal bacterial contamination, regardless of the use of intraperitoneal antibiotics, and is not associated with hemodynamic compromise.
