Recurrence of common bile duct stones after endoscopic clearance and its predictors: A systematic review.

showed a cut‐off value of ≥13 mm to be associated with a high risk of recurrence of CBD stones, although the cut‐off value did not reach statistical significance, probably due to the small sample size. 23 The possible hypothesis for this finding may be that motility and drainage may be affected in a dilated bile duct which results in stasis with increased lithogenicity.
