“…The ICG dose used in the studies was not standardized. Only Anjama et al calculated the optimal cut-off of ICG for the identification of intersegmental plane as 0.089ml of ICG per unit volume (ml) of the segment [50].…”

Background: Thoracic surgery is a constantly evolving field that require innovative solutions. Invisible near-infrared fluorescence imaging with indocyanine green is an intraoperative technology that could be help for surgeons. Indocyanine green is a nontoxic dye with low rate of adverse reaction. Indocyanine green binds with plasma proteins and lipoprotein that allow a deep tissue penetration, and also the amphiphilic proprieties allow indocyanine green to migrate within lymphatics. Methods:We selected forty-nine previous studies from the literature searching terms "lung cancer", "indocyanine green", "thoracic surgery", "fluorescent images". The topics of the paper were: sentinel lymph node mapping, pulmonary nodes identification, intersegmental plane identification, and other application (pulmonary bullous lesions, bronchopleural fistula, bronchoplasty, pulmonary sequestration, chyle leak, hyperidrosis). Results:In the different applications indocyanine green showed a high identification rate, overall accuracy, sensibility, and specificity.Conclusions: This review describes the advantages and current applications in thoracic surgery of intraoperative near-infrared fluorescence imaging using indocyanine green.

“…One of the failed cases arose from insufficient ICG injection, while the other case was caused by an influx of excess ICG to preserved part. Anayama tested and found out that the optimal cutoff volume of dilute ICG was 8.91% of the predicted volume of the target segment (20).…”

Segmentectomy has played a crucial role in the treatment of early-stage lung cancer after the publication of JCOG0802, which indicated that patients with small-sized peripheral non-small-cell lung cancer could receive better survival from segmentectomy than lobectomy despite a higher local recurrence. The intraoperative identification of the intersegmental plane ensures complete resection of the lesion with sufficient margin so that it is deemed as the critical part of segmentectomy. Diverse methods have been developed to acquire distinguishable and lasting borderline between segments, but none of them is proved perfect. In this review, we searched and classified these techniques that emerged from the beginning when segmentectomy was used for bronchiectasis until now. Comparisons between different ways in mechanisms, facility, and safety were made to depict a comprehensive landscape for surgeons to select fit one. Furthermore, we presented our vision for the future of intersegmental plane identification.

“…A continuous positive airway pressure ventilation was maintained until the start of the operation. In a recent study, determination of the optimal settings was developed (19). They established precisely that the optimal volume of diluted ICG for insufflation was 8.91% of the calculated targeted pulmonary segment volume.…”

To review the different techniques to identify the intersegmental plane (ISP) during pulmonary segmentectomy by video-assisted thoracic surgery (VATS).Background: Pulmonary segmentectomy by VATS is being used increasingly. However, the difficulty in identifying the ISP may remain a technical barrier during the procedure. A 3-dimensional pre-operative planning provides a better understanding of the anatomy. Nevertheless, the surgeon needs intraoperative assistance to identify the ISP correctly. Furthermore, achieving adequate margins is of crucial importance in lung cancer to avoid local recurrence.Methods: Our narrative review focused on the different methods to identify the ISP. This narrative review was based on searches in MEDLINE, PubMed and Google Scholar database. We searched for published articles between 2000 and 2021. Keywords used for the research included "segmentectomy by VATS", "thoracoscopic segmentectomy", "ISP" and "intersegmental demarcation". We reported the pros and cons for each technique. We sort the methods of ISP demarcation in two categories: bronchial and arterial demarcation. Conclusions:We described five methods to identify the ISP, including four methods involving bronchial demarcation and one method involving arterial demarcation. All methods can permit to identify the ISP with a high rate of success. The oncological efficacy of the different techniques remains unknown.
