To analyze the efficacy and safety of Titanium clip-assisted lesion-location under colonoscopy for colorectal cancer surgery.

The clinical data of 121 patients with colorectal cancer underwent surgical treatment from March 2017 to March 2020 were analyzed retrospectively. They were divided into the simple group (simple colonoscopy, n=53 cases), and the combined group (titanium clip assisted lesion-location under colonoscopy, n=68 cases), Statistical analysis were performed by using SPSS24.0 software, the perioperative data were expressed as (±s), the difference between the two groups were examined by using t test. The locating effect and complications were examined by using χ² test. A P value of <0.05 was considered as statistically significant difference.

The concordance rate of the location with the actual tumor location in the combined group was higher than that of the simple group in the right colon, left colon, and sigmoid colon (100.0%, 100.0%, 95.2% vs. 73.3%, 73.3%, 72.2% respectively, P<0.05). The average operation time and intraoperative detecting time of the combined group were much shorter than those of the simple group respectively, and the intraoperative blood loss was lower than that of the simple group (P<0.05). There was no significant difference between two groups in terms of the incidence of perioperative complications (P>0.05).

Titanium clips assisted lesion-location under colonoscopy for colorectal cancer surgery could accurately locate the tumor site, for guiding the location of Trocars and the selection of surgical incision, with shortened the operation time and more safety.
