Device-assisted enteroscopy: Are we ready to dismiss the spiral?

Motorized spiral enteroscopy (MSE) is the latest advance in device-assisted enteroscopy. Adverse events related to MSE were discussed in a recent large systematic review and meta-analysis and were directly compared with those of balloon enteroscopy in a case-matched study and a randomized controlled trial. Following the real-life application of MSE, an unexpected safety issue emerged regarding esophageal injury and the technique has been withdrawn from the global market, despite encouraging results in terms of diagnostic and therapeutic yield. We conducted an Italian multicenter real-life prospective study, which was prematurely terminated after the withdrawal of MSE from the market. The primary goals were the evaluation of MSE performance (both diagnostic and therapeutic) and its safety in routine endoscopic practice, particularly in the early phase of introduction in the endoscopic unit. A subanalysis, which involved patients who underwent MSE after unsuccessful balloon enteroscopy, demonstrated, for the first time, the promising performance of MSE as a rescue procedure. Given its remarkable performance in clinical practice and its potential role as a backup technique following a previously failed enteroscopy, it may be more appropriate to refine and enhance MSE in the future rather than completely abandoning it.
