| Scientific title | Impact of rectal washout on bacterial contamination caused by transrectal access for natural-orifice transluminal endoscopic surgery (NOTES): a randomized controlled trial |
| Study acronym | NOBACT II |
| Study objectives | The null-hypothesis states that the probability of bacterial contamination caused by transrectal access measured by a swab of the circular staplers center rod is the same for experimental intervention and control intervention. The alternative hypothesis states that the experimental interventions and the control intervention perform differently in terms of primary efficacy endpoint. |
| Ethics approval(s) | Ethics Committee of the University of Heidelberg approved on 25/05/2011, (ref: S-396/2010) |
| Health condition(s) or problem(s) studied | Patients undergoing sigmoid resection or left hemicolectomy |
| Intervention | Experimental intervention: 1. Rectal washout with 5% povidon iodine using an applicator 2. Rectal washout with sodium chloride (NaCl) using an applicator Control intervention: Rectal washout with NaCl using an irrigation syringe |
| Intervention type | Drug |
| Phase | Not Applicable |
| Drug / device / biological / vaccine name(s) | 5% povidon iodine |
| Primary outcome measure(s) |
Bacterial contamination at the circular staplers center rod following experimental intervention (rectal washout with 5% povidone iodine using an applicator) and control intervention |
| Key secondary outcome measure(s) |
1. Bacterial contamination at the circular staplers center rod following experimental intervention (rectal washout with NaCl using an applicator) |
