“…Therefore usually orthograde mechanical bowel preparation is performed in combination with a rectal washout [12]. However, mechanical bowel preparation is not well tolerated by patients and it has been shown that contamination of the rectal mucosa remains high even after extensive rectal washout [13,14].…”

Background Transrectal Natural Orifice Transluminal Endoscopic Surgery is currently limited by the inherent risk of surgical site infection due to peritoneal contamination after rectotomy. Coloshield has been developed as a temporary colon occlusion device to facilitate rectal washout. However, effectiveness and safety has not been evaluated in humans. Methods Twenty-two patients have been randomly assigned to undergo proctological intervention with a rectal washout with and without the use of Coloshield. Patients and assessors were blinded. Boston Bowel Preparation Scale (BBPS) has been determined 30 min as well as immediately after rectal washout. Feasibility, pain, intra- and postoperative morbidity as well as bowel function and continence 6 weeks after surgery were assessed. Results BBPS 30 min after rectal washout with and without Coloshield was in mean 2.42 ± 1.02 and 2.12 ± 0.89 (p = 0.042). Mean BBPS immediately after rectal washout was 2.39 ± 1.02 and 2.24 ± 0.66 (p = 0.269). Mean BBPS immediately after rectal washout and 30 min thereafter did not differ (p = 0.711). Coloshield application was feasible without any complications. The median (interquartile range) numeric rating scale for pain 4 h after surgery was 1 (0–1) and 3 (0–4) (p = 0.212). Six weeks after surgery 0/11 and 1/11 patients suffered from evacuation difficulties (p = 1.0) and the median Vaizey–Wexner score was 1 (0–3) and 1 (0–2) (p = 0.360). Conclusions Coloshield application in humans is feasible and safe. Slight benefits in rectal preparation by washout are found when Coloshield is used. Colon occlusion by Coloshield for transrectal NOTES should be evaluated within clinical studies. Trial registration Clinicaltrials.gov NCT02579330
