Abstract
Background
Preventing benign strictures following esophageal endoscopic submucosal dissection (ESD) remains difficult, and finding a safe, effective, and simple management method is vital. We previously reported that rosuvastatin significantly reduced the incidence and severity of strictures in a rabbit model of esophageal stricture. Accordingly, in this study, we compared the effects of statins, steroids, and botulinum toxin A (BTX-A) on stricture prevention after ESD involving more than three-fourths of the luminal circumference.
Methods
Of the 1019 ESD cases treated between January 2015 and December 2020, 246 met the inclusion criteria, with 21 cases excluded due to loss to follow-up, tumor recurrence, death, or need for additional surgery, radiotherapy, and/or chemotherapy. Of the 225 included cases, 145 received no intervention, while the remaining 80 were treated: 16 with oral steroids, 20 with topical triamcinolone acetonide (TA) injection, 21 with topical BTX-A injection, and 23 with statins.
Results
The occurrence stricture rate in the statins group (17.4%, 4/23) was significantly lower than in the non-intervention (75.2%, 109/145, P = 0.000), oral steroids (56.3%, 9/16, P = 0.011) and TA injection (50%, 10/20, P = 0.023) groups, but comparable to in the BTX-A injection (38.1%, 8/21, P = 0.124) group. The dysphagia score was lower in the statin than non-intervention group (P = 0.000). Although there was no significant difference in the number of required dilations between groups, the maximum number of dilations in the statins group was only six.
Conclusions
Statins may be a potential treatment to prevent esophageal strictures after extensive ESD; however, clinical trials should be conducted to validate this.
