Abstract:
Objective To explore the clinical effects of three different pre cutting methods in difficult intubation of ERCP.
Methods The clinical data of 96 patients with ERCP difficult intubation and further treated by preresection from January 2018 to June 2021 were analyzed retrospectively. According to different intubation methods，they were divided into three groups：The DGT group（n=34 cases），TPS group（n=32 cases），DGT+TPS group（n=30 cases）. SPSS 22.0 was used to process the data. Postoperative complications were analyzed by χ2 test. Perioperative related indicators and other measurement data were represented by（
±
s）.
One-way ANOVA was performed for comparison between multiple groups.
LSD-t test was performed for comparison between the two groups.
P<0.05 was considered statistically significant.
Results There were significant differences in operation time，intubation time and postoperative hospital stay among the three groups（P<0.05）. and the combined group was significantly lower than the DGT group and TPS group（P<0.05）.There were no significant differences in the success rate of intubation and incidence of total postoperative complications among the three groups（P>0.05）.
Conclusion In ERCP difficult intubation，DGT combined with TPS can effectively shorten intubation time，reduce the operation time，and reduce the risk of postoperative complications compared with the single application of DGT or TPS，thus benefiting patients' postoperative recovery.
