Abstract:
Objective To evaluate the effectiveness of mouth care combined with intestinal and endoscopic working channel flushing for ERCP related cholangitis and to investigate the mechanisms.Methods A total of 284 patients who underwent ERCP were divided into the amikacin group (n =96),the saline group (n =95) and the control group (n =93).Specimens were collected before cannulation (Sample 1),the first access to the bile duct (Sample 2) and at the end of ERCP (Sample 3).All the samples underwent bacterial culture and colony counting.Incidence of ERCP related cholangitis and bacterial results were recorded.Results The incidences of ERCP related cholangitis were 7.3％ (7/96),8.4％ (8/95)and 18.3％ (17/93)in amikacin group,saline group and control group respectively,with significant differences among three groups (x2 =6.861,P =0.032).The positive rate of bacterial culture of Sample 1 in the amikacin group,saline group and control group were 6.3％ (6/96),25.3％ (24/95) and 28.0％ (26/93) (x2 =16.833,P =0.000),respectively.The positive rate of bacterial culture of Sample 2 in amikacin group,saline group and control group were 6.3％ (6/96),16.8％ (16/95) and 24.7％ (23/93)(x2 =12.206,P =0.002),respectively.The positive rate of bacterial culture of Sample 3 in amikacin group,saline group and control group were 7.3％ (7/96),17.9％ (17/95) and 33.3％ (31/93) (x2 =20.713,P =0.000),respectively.Conclusion The procedure of ERCP can bring the intestinal bacteria into the bile duct,which could be reduced by mouth care combined with intestinal and endoscopic working channel flushing.And the incidence of ERCP related cholangitis can be effectively reduced.
