Abstract: Objective To explore the effect of  indocyanine green（ICG）for sentinel lymph node mapping in laparoscopic fertility-sparing surgery for early cervical cancer. Methods Clinical data of 24 patients which underwent laparoscopic radical trachelectomy and sentinel lymph node biopsy were retrospectively analyzed. All patients were treated with ICG mapping. The detection rates，lymph node distribution and quantity were analyzed. Results Twenty-four  patients were included. Intraoperative ICG mapping detected at least one SLN in 24 patients （24/24），while bilateral mapping was achieved in 93.8% of cases（22/24）. There was no difference in detection rates between different injection method and patients with and without prior conization（P＞0.05）.A total of 210 SLN were resected in 24 patients，with an average of 8.75 SLN per patient（3-19 SLN）. 139 SLN are located in the iliac vessels，accounting for 66.19% （139/210）. Conclusions Sentinel lymph node mapping can be effectively applied to laparoscopic fertility-sparing surgery for early cervical cancers with strict indication and operational procedures.
