The Definitive Diagnosis, Dye Marking and Treatment of an 8mm Lesion in One Single-Anesthesia Event
LungVision + Ethicon Monarch Robot - March 13, 2023

Lesion Characteristics

Lesion Size (diameter): 8mm

Lesion Location: Left Upper Lobe (LUL) pleura-based, solid lesion

Visible on Fluoro: No

REBUS Verification: No


Case Details

Procedure Time: 30 Minutes for bronchoscopy procedure

Final Pathology Report: Squamous Cell Carcinoma


Patient Background

A 70-year-old female patient with no smoking history but a history of head and neck cancer presented with an 8mm LUL nodule and an enlarged hilar lymph node.


The Procedure

Planning

To begin planning of the LungVision™ system, a preoperative CT is loaded and the lesion is marked and contoured so the system knows the lesion size, shape and location before the procedure. During this step, the LungVision system derives the airways from the preoperative CT and can be a complete navigation bronchoscopy system for those looking to use it without a robotic or ENB system. If needed, a virtual bronchoscopy highlighting the preferred pathway to the lesion is provided. In this instance, the Ethicon MONARCH™ robotic bronchoscopy platform was used for navigation. 


Registration

LungVision registration requires two C-arm spins – one around the main carina and another around the lesion. These two spins generate an initial C-Arm Based Computed Tomography (CABT) scan providing real-time lesion location.

Navigation

The Ethicon MONARCH™ robot’s electromagnetic navigation (EMN) system was used for navigation. 


Tool-in-Lesion Confirmation

Once at the target lesion location as shown by the Ethicon MONARCH™ robotic bronchoscopy platform, a biopsy needle was extended down the working channel of the bronchoscope and another C-arm spin was performed to better understand the spatial relationship between the tool and the lesion. The imaging acquired from this CABT spin confirmed that the tool was within the lesion.

LungVision’s Any Tool 3D View also showed tool-in-lesion confirmation. 


Biopsy and Dye Marking for Lobectomy

After obtaining tool-in-lesion confirmation, biopsy samples were acquired via biopsy needle with the help of LungVision’s real-time, augmented fluoroscopy.

There was no ROSE on site but the Aquyre Biosciences CelTivity Biopsy System was used in the procedure to confirm malignant cells in the biopsy samples provided.

After confirming malignancy with CelTivity on the first pass, a fiducial coil dipped in indocyanine green (ICG) was placed at the lesion location using LungVision’s real-time augmented fluoroscopy to assist in evaluation for a Robotic Assisted Lobectomy. A segmentectomy was not possible due to the fact that the hilar lymph nodes were also involved. 


Under LungVision augmented fluoroscopy, fiducial coils dipped in were used to dye mark the lesion for immediate robotic-assisted lobectomy.

Final Pathology 

Squamous Cell Carcinoma


Conclusion

LungVision's AI-driven intraoperative CT imaging provided the real-time imaging required to confirm tool-in-lesion and accurately dye-mark the lesion for robotic-assisted lobectomy so that this patient could be definitively diagnosed, staged, and treated in one single-anesthesia event. This patient went home two days later.
