ObjectiveTo explore the factors related with difficulty of laparoscopic cholecystectomy (LC) for acute calculus cholecystitis.
MethodsA total of 245 patients were retrospectively divided into two groups: easy group（123patients）and difficult group(122patients, including 32patients of conversion to OC )based on surgery time and LC or OC.
ResultsThere were statistical differences between the groups in regards to preoperative body temperature, white blood cell count, surgical timing, the thickness of gallbladder wall, gallbladder volume, and diameter of common bile duct (all P<0.05); and there were obvious statistical differences between the 2 groups in thickness of gallbladder wall, gallbladder volume, diameter of common bile duct, stone impaction in the neck of gallbladder,and the condition of Calot′s triangle during operation (all P<0.01).
ConclusionsFactors related to difficulty of LC in acute calculus cholecystitis include elevated body temperature,increased white blood cell count,thickened gallbladder wall,increased gallbladder volume,common bile duct diameter more than 8 mm,stone impaction in neck of gallbladder and unclear anatomy of Calot′s triangle.
