Background and aims
Endoscopic submucosal dissection (ESD) for superficial esophagus squamous cell carcinoma (SESCC) may cause esophageal stricture and related dysphagia symptoms, especially when the lesion is widespread. Endoscopic balloon dilation (EBD) is the prior choice to treat post-ESD stricture. However, certain patients show poor response to EBD treatment and frequent dilations are required. We perform radial incision and cutting combined with intralesional steroid injection to manage refractory stricture. The study aims to evaluate the safety and efficacy of this new combined treatment.
Methods
From October 2017 to February 2019, 25 patients who accepted repeated EBD because of refractory stricture after extensive ESD for large SESCC were enrolled. Radial incision and cutting followed by local steroid injection was performed on all the patients, and therapeutic EBD was conducted to treat recurring stricture after combined treatment. The incidence of recurrent stricture, clinical outcome of combined treatment, and following therapeutic EBD, procedure-related adverse events were assessed and analyzed.
Results
During the follow-ups, the incidence of recurrent esophageal strictures was 92%. Combined treatment reduced the severity of stenosis and lowered the corresponding dysphagia scores significantly, compared with previous EBD. Mean symptom-relief duration of EBD was prolonged significantly from 29.9 to 76.0 days. Perforation was observed in one patient during operation and successfully sealed with metal clips.
Conclusions
Combination of radial incision and cutting with steroid injection is a safe and feasible treatment for esophageal refractory stricture after extensive ESD, appearing to improve the therapeutic EBD outcome and maintain a longer symptom-relief duration.
