Tracy BM, Paterson CW, Kwon E, et al. - Given the uncertainty concerning the optimal timing for cholecystectomy after endoscopic retrograde cholangiopancreatography (ERCP) for common bile duct (CBD) stones, researchers herein examined if a delay between procedures would result in more biliary complications and longer hospitalizations. The study cohort comprised 349 patients who underwent the same admission cholecystectomy after ERCP for CBD stones at 12 US medical centers. Stratification of the cohort was done by time between ERCP and cholecystectomy: ≤ 24 hours (immediate), > 24 to ≤ 72 hours (early), and > 72 hours (late). A shorter postoperative LOS and hospital LOS were observed in correlation with undergoing an immediate cholecystectomy following ERCP. Seemingly, more common were rates of CBD explorations and conversion to open after 24 hours.
