BACKGROUND: Preceding endoscopic retrograde cholangiography (ERC) in patients with choledochocystolithiasis impedes laparoscopic cholecystectomy (LC) and increases risk of conversion. We studied the influence of time interval between ERC and LC on the course of LC.
METHODS: All patients treated for choledochocystolithiasis with ERC and LC during 1996-2001 were studied retrospectively, comparing the course of LC in three time interval groups; LC<2, 2-6, and>6 weeks after ERC.
PRIMARY OUTCOMES: adhesions, bile duct injury, operating time, and conversion-rate.
RESULTS: Eighty-three patients were studied (group 1, n = 23; group 2, n = 15; group 3, n = 45). Adhesions, operation time, and bile duct damage did not significantly differ between the groups. The conversion rate in group 2 is significantly higher compared to group 1 (p = 0.027, OR 11 (1.13-106.8)) CONCLUSIONS: A higher conversionrate of LC is found 2-6 weeks after ERC compared to LC within 2 weeks. However, further research is needed to gain more reliable data on whether this is caused by timing.
