Background and study aimsColonoscopy is the cornerstone of diagnosing colonic diseases. Investigators have evaluated the effectiveness of antispasmodic agents in colonoscopy with conflicting evidence. The aim of this study is to determine the efficacy of enteric coated peppermint oil capsules (Colpermin®), an antispasmodic agent, on outcomes during colonoscopy.Patients and methodsA total of 80 patients undergoing elective colonoscopy were recruited and randomized in a double blinded fashion to receive either placebo or peppermint oil capsules administered 4 h prior to the procedure.ResultsPeppermint oil capsules did not affect caecal intubation time when compared with placebo. Patients' tolerance, endoscopist's satisfaction and demand on sedation were also not affected.ConclusionThis randomized controlled trial does not support the routine use of peppermint oil capsules prior to colonoscopy as a tool for procedure optimization, and patients' and endoscopist's satisfaction.
