Abstract

Purpose The effect of preoperative endoscopic tattooing (ET) on accurate colorectal cancer localization and resection has been well established. However, its effect on lymph node (LN) retrieval remains unclear. The purpose of this study was to systematically compare LN retrieval between patients with colorectal cancer who underwent preoperative ET and those who did not. Methods A systematic search for relevant studies was conducted using the following databases: PubMed, Embase, and Web of Science. Studies that compared LN retrieval in patients with colorectal cancer with and without preoperative ET were included. Weighted pooled odds ratio (OR) and mean difference (MD) with the corresponding 95% confidence intervals (CIs) for all outcomes using the random-effects model were calculated. Results 10 studies, including 2231 patients with colorectal cancer were included. Six studies reported total LN yield and showed significantly higher LN yield in the tattooed group (MD:2.61; 95% CI:1.01–4.21, P = 0.001). Seven studies reported the number of patients with adequate LN retrieval and showed a significantly higher number of patients with adequate LN retrieval in the tattooed group (OR:1.89, 95% CI:1.08–3.32, P = 0.03). However, subgroup analysis revealed that both outcomes were only statistically significant in patients with rectal cancer, and not in patients with colon cancer. Conclusions Our results suggest that preoperative ET is associated with increased LN retrieval in patients with rectal cancer, but not in colon cancer. Further large-scale randomized control trials are necessary to validate our findings.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
