Comments on the study comparing multiple stents and single stent insertion for chronic pancreatitis

We read with great interest the recently published study on comparing multiple stents and single stent insertion for pain relief in chronic pancreatitis (CP) [1]. The author concluded that treatment with a single stent was associated with better clinical outcome compared to treatment with exclusively two stents during the stenting period. However, we found some flaws in the study design that might have made the conclusion inaccurate.
