RESUMO
Objective To compare the effect of different intestinal loop labeling methods under single balloon enteroscopy for ERCP. Method From June 2015 to May 2017, 36 cases of single balloon enteroscopy assisted ERCP patients, according to the study period divided into A, B, C three groups, In group A, the afferent loops were confirmed by titanium clips, labeled intestinal loops, and the B group was identified by methylene blue labeling and intestinal loops, and the C group was the control group, the operation time of the 3 groups was recorded (the starting time of operation, the time of reaching the nipple of the input loop or the time of the Roux-en-Y biliary anastomosis), the incidence of complications and the success rate of operation. Results The operation time was 42.17 min in group A and 59.83 min in group C, and there was significant difference between the two groups (P < 0.01),There was no statistically significant difference between group A and group B, group B and group C (P > 0.05), the complication rate and the operation success rate were not statistically different between the three groups (P > 0.05). Conclusion The operation time of the input loop at the time of ERCP assisted by single balloon enteroscopy has a clear advantage over the examination of the intestinal loop with a titanium clip.
