Case Study N°3 Effectiveness of OPELAIII in Breast Surgery

Dr. Seigo Nakamura Professor, Division of Breast Surgical Oncology, Department of Surgery, Showa University School of Medicine Open surgery in recent years in the field of breast oncology has increasingly shifted towards small incision even in deep areas because of the emphasis not only on minimal invasiveness but also on more esthetically favorable outcome. This time, we have asked Dr. Seigo Nakamura from the Division of Breast Surgical Oncology at Showa University to evaluate the effectivity of OPELAⅢ in open surgery of the breast, wherein the postoperative visual esthetic is always considered important. The brightness of OPELAⅢ penetrates even a deep and narrow surgical field This was a case of mastectomy where a tumor about 2 cm was palpated at upper-outer part of the left breast and was diagnosed as cancer after a biopsy. The surgical field was an incision of about 15 cm in length. The flesh closer to the incision could be dissected with relative ease, but as the surgery progressed deeper flaps of tissue began to form. And when the surgical field reached the depth near the end of the breast, OR light alone was no longer sufficient. It was then that OPELAⅢ showed its effectiveness in supplementing the light environment (Fig. 1). To inflate the breast back to its natural form after mastectomy, it would be ideal to leave as much normal skin as possible, which meant that the flaps need to be larger, essentially making the surgical field deeper and narrower. However, due to its ability to illuminate the depths even with narrow incision, OPELAⅢ overcame this antinomy, demonstrating its usefulness especially from an esthetic standpoint. Fig. 1Deep muscle tissue/ blood vessel can be recognized even when the large flap is formed OPELAⅢ is useful in axillary lymph node dissection as it illuminates exactly where I want to see In this surgery, the sentinel l ym p h n o d e w a s j u s t b e l o w t h e intercostobrachial nerve, which was another reason requiring deep incision (Fig. 2 and 3). Also, the subsequent axillary lymph node dissection was carried out while having to peer into a depth of 15 to 20 cm as the patient was rather overweight. It is extremely challenging to illuminate deep into the axilla with only the OR light. Even when the angle and focus are adjusted properly Fig. 2 eep inside where the sentinel lymph node used to be D 　　　 ON means when OPELAⅢ is lit. sentinel lymph node used to be It can be clearly identified that the intercostobrachial nerve runs laterally as the surgery progresses

at first, the area I want to see keeps changing as I separate the surrounding tissues during operation. So, the angle and focus needs to be adjusted repeatedly. There are retractors with lights on the tip, but they do not always illuminate where I really want to see. The advantage of using OPELAM is that the surgeon can adjust the light to illuminate exactly where he/she wants to see at will. I would say it is particularly suitable for procedures such as axillary lymph node dissection. The axilla contains the intercostobrachial nerve. Damaging it may result in paralysis of the upper arm....
