Autologous esophageal mucosa transplantation to prevent esophageal stricture after endoscopic submucosal dissection: promising, but too early to draw a conclusion

We read with great interest the article by Liao et al,1 who explored the feasibility and efficacy of endoscopic transplantation of autologous esophageal mucosa to prevent esophageal stricture after circumferential endoscopic submucosal dissection (cESD). Although stricture occurred in 88.9% (8/9) of the cases, this approach nearly halved the mean number of dilation sessions needed. In addition, the authors concluded that transplantation of autologous esophageal mucosa could be a safe way of relieving the severity of esophageal stricture after cESD.
