Prevention of acute pancreatitis and hyperamylasemia induced by ERCP with the useing of somatostatin in different period / 重庆医学

ABSTRACT

Objective To investigate the preventive role of somatostatin in acute pancreatitis and hyperamylasemia induced by endoscopic retrograde cholangiopancre aticography (ERCP) in different periods .Methods 570 cases were divided into four groups , the preoperative group(127 cases) ,the postoperative group(153 cases) ,the whole group(189 cases) and the control groups(101 ca-ses) ,and occurrences of acute pancreatitis and hyperamylasemia were observed .6 h before the operation ,the preoperative group was given 3 mg somatostatin per 12 h by microdosis venous pump .In 12 h after the operation ,the postoperative group was given 3 mg somatostatin per 12 h by microdosis venous pump ,the whole group was given somatostatin 6 h before and 12 h after the operation , the control group was injected normal saline .Measurement of hyperamylasemia was made in 24 h after ERCP ,and clinical manifes-tations of acute pancreatitis were also observed .Results The incidences of PEP and hyperamylasemia were 4 .04% ,23 .86% ,re-spectively .The incidences of hyperamylasemia among the four groups were 23 .62% ,21 .57% ,13 .23% and 47 .52% ,and the inci-dences of PEP were 3 .15% ,4 .58% ,1 .59% ,8 .91% .The incidences of hyperamylasemia and PEP in somatostatin used groups were statistical lower than the control group(P<0 .05) .Compared with the preoperative group and the postoperative group ,the incidence of hyperamylasemia in the whole group had significant difference(P<0 .05) .Compare witn the postoperative group ,the incidence of PEP in the whole group also had significant difference(P<0 .05) .Conclusion Use of somatostatin can reduce the incidence of PEP and hyperamylasemia ,and the use of somatostatin before and after the operation have a better preventive effect .
