Introduction: The current study examines the feasibility of robot-assisted breast surgery guided by indocyanine green (ICG) and describes an efficient step-by-step robot-assisted breast surgery.


Methods: We collected the data of patients who underwent lumpectomy (robot-assisted surgery and conventionally open surgery) in our institution and presented a step-by-step procedure of robot-assisted lumpectomy using ICG in Video. Robot-assisted lumpectomy was performed in patients with a benign pathology. Clinicopathological characteristics, operation information, postoperative complications, and aesthetic outcomes were analyzed.


Results:

A total of 60 patients were included in this study, 22 of whom underwent a robot-assisted lumpectomy and 38 received a conventionally open lumpectomy. The age, BMI (Body Mass Index) and mean tumor size of robot-assisted lumpectomy group and conventionally open lumpectomy group were comparable (P >0.05). All patients were premenopausal except 2 patients. In terms of pathological results, of 22 patients in robot-assisted lumpectomy group, 20 had breast fibroadenoma, 1 had phyllodes tumor and 1 had phyllodes tumor. Of 38 patients in conventionally open lumpectomy group, 28 had breast fibroadenoma, 8 had intraductal papilloma and 2 had phyllodes tumor. The length of incision was significantly shorter in robot-assisted surgery group than that in conventionally open surgery (3.93 cm VS 4.47 cm, P< 0.05). There was no significant difference with respect to intraoperative blood loss in two groups (P >0.05). With regard to incidence of postoperative complications, there was no significant difference in two groups. 2 patients in robot-assisted surgery group and 3 in conventionally open surgery group developed a mild wound infection and were healed after dressing change. Of note, none of patients who underwent robot-assisted surgery showed movement disorders of the upper extremities after surgery. There was no significant difference in the circumference of upper arms before and after robot-assisted surgery, demonstrating that robot-assisted lumpectomy may not incur the lymphedema for a short term. The total operation time of robot-assisted lumpectomy group was significantly longer compared with that in conventionally open lumpectomy group. Patients in robot-assisted surgery group were satisfied with aesthetic outcomes.


Conclusions:

Robot-assisted breast surgery using indocyanine green guided by ultrasound, yielding a good aesthetic outcome, is a safe alternative of potential value for patients. To our experience, women with tumor larger than 2cm and located in lower inner quadrant are preferable candidates for this technique.

Learning Objectives:

  • Upon completion, participant will be able to be presented with a procedure of robot-assisted breast surgery.
  • Upon completion, participant will be able to better understand the indication of robot-assisted surgery in breast surgery.
  • Upon completion, participant will be able to learn about the value of ICG in tumor localization in robot-assisted breast surgery.
