ABSTRACT
Objective To evaluate the efficacy and safety of combined use of insulated-tip knife, titanium clips and transparent caps in the resection of large pedunculated colorectal polyps. Methods Therapeutic method: with the assistance of transparent cap, 1~3 titanium clip(s) were applied to the base of the stalk to block blood supply of large polyps and then insulated-tip knife was utilized to resect polyps by cutting the stalk. Research method: retrospectively analyze the clinical data of 45 large pedunculated colorectal polyps (head ≥ 2.0 cm) which were treated by the method mentioned above from January 2014 to December 2015. Statistics of procedure time, clip numbers, complication rates were used to assess the effect of the treatment. Results 45 large polyps were successfully removed one time without any severe complications of bleeding or perforation during procedure except a very small amount of blood were oozing from the cutting edge in 3 cases. There were also no delayed complications of bleeding or perforation after procedure. The average number of titanium clip was 2.7 and the average operating time was (5.7 ± 1.2) min (range 3 ~ 12 min). Conclusion Combined application of insulated-tip knife, titanium clips and transparent cap inthe resection of large pedunculated colorectal polyps is safe, effective and convenient to conduct.
