Description
Wataru Yoshioka and eight colleagues compared two shapes of plastic stent for draining bile ducts blocked by cancer low in the duct. One design ends in double half-pigtail curls, the other runs straight. Their single-center review covered procedures done from late 2022 into 2026, focusing on each patient's first stent placement: twenty with the curled design and fifty-two with the straight one.
Time until the stent blocked or slipped again came out nearly identical between designs, at just under four months, and blockage rates matched too. One difference stood out: no curled stent migrated, while seven straight stents slipped out of place. Overall side effect rates also looked similar. The authors conclude the curled design buys no extra open time, so its real promise, if any, lies in holding position rather than resisting clogging.
