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. We examined the feasibility and efficacy of a novel treatment technique for refractory HJAS, called balloon enteroscopy-assisted radial incision and cutting (BE-RIC).
Methods:
Between January 2016 and June 2018, 11 patients with refractory HJAS that recurred after balloon dilation and/or stent placement, underwent BE-RIC. We evaluated the technical success, clinical success, adverse events, and re-stenosis rates associated with BE-RIC.
Results:
The technical success rate of BE-RIC was 91 % (10/11). Clinical success was achieved in all patients who underwent technically successful procedures. The procedure-related adverse event rate was 9 % (1/11). No re-stenosis was observed during the follow-up period; 9 patients were followed up for more than 6 months, and of these, 5, 4, and 2 patients were followed up for more than 12, 18, and 24 months, respectively, without re-stenosis.
Conclusions:
BE-RIC for refractory HJAS showed favorable results. BE-RIC might be a useful option for treating refractory HJAS.

01:30Esophageal Strictures-I: Introduction
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...

In a radial system with a fault downstream of the third breaker, ideally, only the third breaker will open, isolating the fault and interrupting the load connected beyond it. The second breaker has a longer delay setting,...

The radial pulse, located at the wrist, is often the preferred site for assessing peripheral pulse because of its accessibility and dependability. The process of determining the radial pulse involves several steps:
