The loop-torque maneuver is a simple technique used to facilitate intubation with an enteroclysis catheter. A braided stainless steel guidewire, 26 cm longer than the one provided with the commercially available set, is used. A loop is formed in its proximal end to facilitate torquing if the catheter engages the greater curvature or coils up in the fundus. The loop-torque maneuver led to successful intubation of all patients in this series and produced less discomfort than the double-back maneuver.
环形扭矩操作是一种用于辅助经肠导管插管的简单技术。使用一根编织不锈钢导丝，其长度比市售套件所配备的导丝长26厘米。在其近端形成一个环，以便在导管卡在胃大弯处或在胃底盘绕时便于扭转。在本系列中，环形扭矩操作使所有患者成功插管，且比双回拉操作产生的不适感更小。
