- Abstract: Objective To investigate the short and long term effects of preincision of pancreatic duct sphincter in different types of patients with difficult intubation by endoscopic retrograde cholangiopancreatography(ERCP).Method A retrospective study was conducted on 100 patients with difficulty in ERCP intubation from January 2019 to June 2020.Patients were divided into a control group(50 cases)and a study group(50 cases)according to different treatment methods.The control group underwent routine ERCP intubation without pancreaticotomy,while the study group underwent preincision of pancreatic duct sphincter on the basis of routine ERCP intubation.Calculate the successful intubation time,successful intubation rate,and length of hospital stay for two groups;Enzyme linked immunosorbent assay was used to detect postoperative C-reactive protein(CRP),interleukin-6(IL-6),and blood amylase levels in two groups of patients;Calculate the incidence of complications related to pre incision surgery in two groups of patients;Follow up the incidence of reflux cholangitis and recurrent pancreatitis in two groups of patients at 3,6,and 12 months after surgery,and evaluate the long-term efficacy of the two groups of patients.Result Compared with the control group,the study group showed a shorter in successful intubation time,and an increase in successful intubation rate(P<0.05).There was no difference in hospital stay between the two groups(P>0.05);Compared with the control group,the study group showed a decrease in CRP,IL-6 and blood amylase levels on the first day after surgery(P<0.05);The postoperative complication rate of patients in the control group was 14.0%,including 4 patients with acute pancreatitis,2 patients with bleeding,and 1 patient with perforation.The postoperative complication rate of patients in the study group was 2.0%,with 1 patient with bleeding.Compared with the control group,the postoperative complication rate of patients in the study group decreased(P<0.05);Compared with the control group,the incidence of reflux cholangitis in the study group decreased at 12 months after surgery,and the incidence of recurrent pancreatitis decreased at 3,6,and 12 months after surgery(P<0.05).Conclusion Preincision of the pancreatic duct sphincter has a mild impact on systemic inflammation in patients with difficult ERCP intubation,with normal blood amylase indicators and no increase in the incidence of postoperative pancreatitis.It can improve the success rate of intubation and has significant long-term efficacy.It is a safe and effective technique which is worth recommending.
