| Background: Balloon enteroscopy-assisted balloon dilation and temporary biliary stent placement are effective for hepaticojejunostomy anastomotic strictures (HJAS), but the re-stenosis rates are relatively high. This study examined the feasibility and efficacy of a novel balloon enteroscopy-assisted radial incision and cutting (BE-RIC) technique for refractory HJAS. Methods: Eleven consecutive patients who underwent BE-RIC for refractory HJAS that recurred after balloon dilation and/or stent placement between 2016 and 2018 were investigated. The study outcomes included technical and clinical success, adverse events, and re-stenosis rates associated with BE-RIC. Results: The technical success rate of BE-RIC was 92% (11/12). Clinical success was achieved in all patients who underwent technically successful procedures. The procedure-related adverse event rate was 8% (1/12). Cholangitis occurred in one patient, but it was mild and improved with conservative management. The median follow-up period after BE-RIC was 55 months. Two re-stenosis was observed during the follow-up period; the re-stenosis rate was 18%. The time to re-stenosis after BE-RIC was significantly longer than that after previous treatments of balloon dilation and/or stent placement (P <0.001). Conclusions: This is the first study investigating the long-term outcomes of BE-RIC for refractory HJAS, with favorable results. BE-RIC may be a useful option for treating refractory HJAS. |
