Endoscopic retrograde cholangiopancreatography (ERCP) for patients with digestive tract reconstruction is a difficult procedure from an anatomical point of view. A short-type double-balloon enteroscope has a 2.8-mm working channel and a 152-cm working length, and its advantage is that it can accommodate most conventional devices for ERCP. Although the shorter length compared with the long-type balloon-assisted enteroscope (BAE) was suspected of making it difficult or impossible to reach the blind end, in fact, the success rate of reaching the blind end with the short type is similar to that with the long- type BAE. In addition, the success rate of ERCP-related procedures with the short type is satisfactory. However, it remains controversial as to which BAE is more suitable for this procedure. Further randomized controlled trials by high-volume centers are warranted.
内镜逆行胰胆管造影术（ERCP）对消化道重建患者来说，从解剖学角度来看是一项具有挑战性的操作。短型双气囊小肠镜具有 2.8mm 的工作通道和 152cm 的工作长度，其优点是它可以容纳大多数用于 ERCP 的常规设备。虽然与长型气囊辅助小肠镜（BAE）相比，短型的长度较短，可能使其难以或无法到达盲端，但实际上，短型到达盲端的成功率与长型 BAE 相似。此外，短型进行 ERCP 相关操作的成功率也令人满意。然而，哪种 BAE 更适合该操作仍存在争议。有必要由高容量中心进行进一步的随机对照试验。
