Author contributions: Tou LZ completed the main writing of the paper; Wu D, Jiang C, and Zheng JJ served as assistants and participated in the surgery; Sun Z and Li JH conducted post-operative management for the patient; Que HF and Luo DS reviewed the relevant literature and assisted in the completion of the paper; Xu HT was the chief surgeon for the operation and performed the surgical procedures; Beisani M made revisions and provided guidance for the paper. All authors have read and approved the final version to be published. The indocyanine green (ICG) tracer-guided robotic segmental gastrectomy (SG) operation in this case was performed by Xu HT from Lishui Central Hospital. Xu HT provided a lot of guidance for the preoperative assessment and postoperative rehabilitation. Therefore, he is the corresponding author of this article. During the writing of the case report, I received a lot of help and guidance from Beisani M of Barcelona, Hospital Der Mar. We conducted many discussions and exchanges regarding ICG and SG, which had a significant impact on the writing of the discussion part of this article. Therefore, Professor Beisani, as a co-corresponding author, participated in the publication of this article.

Abstract
BACKGROUND
Robotic surgery has been widely used in pylorus-preserving gastrectomy (PPG). Segmental gastrectomy (SG) is a classic surgical method in PPG. Indocyanine green (ICG) can increase the number of lymph nodes dissected.
CASE SUMMARY
We report ICG tracer-guided SG using a robotic system in a 62-year-old female patient with early gastric cancer. It took 23 minutes for robotic setup, 130 minutes for dissection, and 60 minutes for digestive tract reconstruction. There were no postoperative complications such as abdominal infection, delayed gastric emptying, or gastroesophageal reflux. The patient was discharged on postoperative day 9. The pathological staging was pT1bN0M0.
CONCLUSION
This report indicates that ICG tracer-guided robotic SG is feasible and safe for some patients with early gastric cancer.
Core Tip: We report indocyanine green (ICG) tracer-guided segmental gastrectomy (SG) using a robotic system in a 62-year-old female patient with early gastric cancer. There were no postoperative complications such as abdominal infection, delayed gastric emptying, or gastroesophageal reflux. This report indicates that ICG-tracer-guided robotic SG is feasible and safe for some patients with early gastric cancer.
