The Efficacy of Pancreatic Duct Stenting With Rectal Indomethacin in Preventing Post-ERCP Pancreatitis

The Efficacy of Pancreatic Duct Stenting With Rectal Indomethacin in Preventing Post-ERCP Pancreatitis

Clinical Research on the Prophylactic Efficacy of Pancreatic Duct Stenting Combined With Rectal Indomethacin Drug on Post Endoscopic Retrograde Cholangiopancreatography Pancreatitis

With the development of endoscopic technology, ERCP has been widely used in the diagnosis and treatment of pancreatobiliary diseases, and has become the first treatment for most of the biliary and pancreatic diseases. Postoperative ERCP pancreatitis (PEP) is the most common and serious complication after ERCP. The purpose of this study was to explore methods for preventing postoperative pancreatitis. Participants: Patients with high-risk factors associated with PEP were included in the no-obvious patients who underwent therapeutic ERCP in our hospital from June 2018 to December 2019. Research methods: Patients were randomly divided into indometacin suppositories, indomethacin suppositories and pancreatic stents. Statistical methods: SPSS 13.0 statistical software was used. The measurement data was expressed as x± s, and t-test or non-parametric test was used. Chi-square test was used for count data.

Patients with high risk factors for PEP who will be examined and diagnosed by ERCP at 2018.06-2019.12 in the First People's Hospital of Hangzhou are randomly divided into two groups. 2. Record the relevant indicators of each group of patients: 1 before and after surgery 3, 12, 24 h serum amylase changes 2 patients with abdominal pain, abdominal distension, fever, vomiting and abdominal signs of change; 3 hospital days; 4 CT severity index (CT severity Index, CTSI score: Balthazar 5 scores were scored as 0 to 4 points; according to the scope of necrosis was divided into no, <33%, 33% to 50%,> 50%, respectively rated as 0, 2, 4 and 6 points. Addition of the two scores is the CTSI score. 5 According to the diagnostic criteria for postoperative ERCP pancreatitis, PEP will be diagnosed in patients with persistent abdominal pain within 24 hours after ERCP and blood amylase increase by more than 3 times the normal value. Observed 2 groups of post-ERCP pancreatitis, severe pancreatitis and adverse events Incidence. 3. Analyze and compare the above indicators and observe the effect of the two methods on the reduction of blood amylase level and incidence of pancreatitis. It is clear that rectal administration of preoperative indomethacin suppository has the same protection against PEP as pancreatic stenting effect.

CT severity Index, CTSI score: Balthazar 5 scores were scored as 0 to 4 points; according to the scope of necrosis was divided into no, <33%, 33% to 50%,> 50%, respectively rated as 0, 2, 4 and 6 points. Addition of the two scores is the CTSI score
