First report of complete enteroscopy from ileocecal valve to pylorus by retrograde motorized power spiral endoscopy

Abstract

AbstractThe development of capsule endoscopy and device-assisted enteroscopy (DAE) revolutionized minimally invasive examination and treatment of small bowel diseases. Limitations of DAE are a great time expenditure and low rates of complete enteroscopy. Recently motorized spiral enteroscopy (MSE) was introduced with shorter procedure times and concurrently greater insertion depths. MSE is also the first device that opens up the possibility to achieve complete enteroscopy in a relevant number of cases by the unidirectional, peroral approach.To our knowledge we present the first published case of complete enteroscopy by retrograde MSE in a 35-year-old female without prior abdominal surgery with direct endoscopic visualization of the pyloric ring. The patient suffered from colonic polyposis syndrome. For the exploration of both colorectum and the small bowel we performed retrograde MSE under propofol sedation. After 60 minutes of advancement, we achieved complete enteroscopy by retrograde identification of the pyloric ring. The procedure could be finished after withdrawal of the endoscope and cold snare polypectomy of 3 small colonic adenomas without any adverse events. Total procedure time was 82 minutes. The patient was discharged one day after the procedure without complaints.It has been proven already that great insertion depths are achievable by retrograde MSE, but this case shows for the first time that even a complete enteroscopy is possible. In conclusion, primary retrograde MSE with no need of tracheal intubation might be a key to more effective, time-preserving, and cost-effective concepts of small-bowel endoscopy in the future.
