Abstract:
To observe the effect of indomethacin suppository 100 mg before endoscopic retrograde cholangiopancreatography (ERCP) on the level of platelet microparticles (PMPs) in patients with post-ERCP pancreatitis (PEP). A total of 191 patients receiving ERCP were collected from June 2019 to October 2020 in the First Affiliated Hospital of Anhui Medical University and were randomly divided into the indometacin group ( n=96) and the control group ( n=95) by random number table method. The indometacin group received 100 mg indometacin suppositories before ERCP and the control group received placebo of equal quality. Levels of PMPs before operation, 3 hours and 24 hours after operation were measured by flow cytometry. The levels of IL-1, IL-6 and TNF-α in the plasma before ERCP, 3 hours and 24 hours after ERCP were also detected. The incidence of PEP in the indometacin group was 5.21% (5/96), which was significantly lower than that in the control group [13.68% (13/95), P=0.044]. The preoperative PMPs level in the indometacin group (1 910.01/μL) was slightly lower than that in the control group (2 351.87/μL) with no significant difference ( P>0.05). The PMPs levels in the indometacin group 3 hours and 24 hours after ERCP (1 671.47 /μL, 862.74/μL) were significantly lower than those of the control group (2 443.75/μL, 2 536.76/μL, both P<0.05). Inflammatory cytokines including IL-1, IL-6 and TNF-α showed the same tendency. Indometacin can reduce the incidence of PEP, for the reason that indometacin may decrease the levels of PMPs.
