Circular incision and cutting, a novel treatment for patients with esophageal cancer with anastomotic stricture after esophagectomy

Endoscopic balloon dilation (EBD) is still considered the standard treatment for patients with anastomotic strictures after esophagectomy. However, repeated dilation sessions are often required to maintain the lumen patency. We therefore developed a novel method called circular incision and cutting (CIC) and compared the efficacy of CIC and EBD among patients with anastomotic strictures after esophagectomy or gastrectomy.In this retrospective study, 71 consecutive patients with esophageal cancer with anastomotic strictures after esophagectomy or gastrectomy between January 2011 and December 2016 were included. Among them, 22 patients received CIC therapy and 49 were treated with EBD.The dysphagia in all patients immediately ameliorated and no serious adverse events requiring further intervention were observed after CIC therapy. Compared with EBD, CIC exhibited a greater score in the difference of dysphagia before and after treatment (1.73 vs 1.16, P = 0.03). Moreover, the interval of restenosis and 6-month lumen patency in CIC had a better effect than that in EBD (88.07 days vs 62.76 days, P = 0.001; dysphagia score 0.63 vs 1.44, P = 0.007).The CIC method may be an effective and safe option for patients with esophageal cancer with anastomotic strictures after esophagectomy.
