Abstract: When talking about lung cancer, it is important to recognize this as the first cause of death of neoplastic origin. The detection of this in early stages has made the emergence of ground glass opacity (GGO) more frequent due to the establishment of lung cancer screening programs, allowing the reduction of morbidity and mortality caused by the same and achieving a curative treatment of it. The management of multiple GGOs depends much on the characteristics of these, however, being multiple and contralateral should be considered surgical resection, always taking into account the stage of the dominant lesion. In this article, we present a case of a 60 years old woman with a bilateral GGO lesions located in segment 3 on both sides. A bilateral uniportal video-assisted thoracic surgery (VATS) anatomic segmentectomy S3 of both lesions was performed in a single stage surgery. The postoperative course of the patient was uneventful.

Introduction

The presence of ground glass opacity (GGO) in a chest computed tomography scan (CT Scan) is a radiological entity that has been booming, mostly after the initiation of screening tests for lung cancer (1-3). Particularly the GGO lesions have been related with non-small cell lung cancers (NSCLCs) specifically the lepidic component of adenocarcinomas (1,2). It is necessary to classify this according to its radiological characteristics. The pathological-radiological correlation allows to make an adequate treatment (1,4,5), observing that the presence of the GGO component is a prognostic factor of cancer in early stages (6-8). Likewise, the appropriate follow-up in combination with the resections of this type of lesions actually is a challenge for thoracic surgeons, even more in cases of persistent or multiples GGOs (9). however, nowadays we observe that sublobar resections [single or combined segments (10)] are rising and giving adequate oncological results and in terms of survival (9,11-13). We present a case of a patient with unusual multiple GGOs placed in the anterior segment in both sides.


Patient and workup

A 50 years old female patient, without previous medical history or symptoms, which screening CT scan shows multiple GGOs in both sides with different diameters, in the right side one of 10 mm, and in the left side two of 14 and 5 mm respectively (Figure 1). She was followed for 3 months with persistence of these lesions. The bronchoscopy and positron emission tomography (PET) CT Scan were not realized. Forced expiratory volume in 1 second (FEV1) was 89.3%. She was planned to perform both resections by a single stage bilateral uniportal video-assisted thoracic surgery (VATS) approach.

Figure 1 Preoperative CT scan shows multiple GGOs in both sides. (A) GGO in the right anterior segment (S3): 10 mm of diameter; (B) GGO in the left anterior segment (S3): 5 mm of diameter; (C) GGO in the left anterior segment (S3) dominant lesion: 14 mm of diameter. GGO, ground glass opacity.

Pre-operative preparation

The operation was scheduled to perform bilateral anterior segmentectomies via uniportal VATS. The patient was intubated with a double lumen endotracheal tube. Prophylaxis with cephalosporin, central venous pressure line and urinary catheters were inserted before the surgery.

Procedure

Under general anesthesia and left lateral decubitus position, a right uniportal VATS approach through a 3-cm incision was performed. Firstly, we dissected the right upper lobe vein and anterior arterial trunk. We proceeded to open the minor fissure, identification of the vessels of S3; V3 and A3 both with two branches (V3a, V3b, A3a and A3b respectively) (Figure 2A), ligation with silk and vascular clips and division of B3 with endo-staplers. In this side, we completed the segmentectomy cutting the parenchyma with endo-staplers. A chest tube (18 french) was placed at the end of the procedure. The patient was turned to a right lateral decubitus position and a 3-cm incision was performed on the left side, fifth intercostal space, middle axillary line. A left uniportal VATS anatomic segmentectomy S3 was performed. We started opening the pleura over the vessels in the left upper lobe. The we dissected and ligated V3 and then the B3 was dissected and divided with an endo-stapler (Figure 2B) This maneuver exposed the artery of the segment (A3) and was divided like in the right side. The inflation and deflation of the lung to demark the limits of the segment was the last step. It was finalized by cutting the lung parenchyma following this landmarks and leaving the distal stump on the resected segment. Hemostasis was proved, and air leak excluded in both sides. We placed 18F chest tube and the wound was closed. The estimated blood loss during the surgery was 50 mL and the total surgical time for both procedures was 90 minutes (Figure 3).

Post-operative management

The post-operative course of the patient was successful without complications. The management of the pain was with patients controlled analgesia (PCA). The post-operative X-ray showed complete expanded lungs without complications (Figure 4). The chest tubes were removed in the 3rd day post-operatory (Figure 5), and the patient was discharged the same day without complications.

The paraffin biopsy results were in the right anterior segment: the bigger one was invasive adenocarcinoma, with 3 cm of margin. In the left anterior segment, the bigger was minimally invasive adenocarcinoma (MIA) and the other was adenocarcinoma in situ (AIS) with 2 cm of margin.


Tips, tricks and pitfalls

  • A complete dissection of the distal part of the vessels provides a better and clear view before transection.
  • Perform segmentectomies require the perfect knowledge of the distal bronchovascular anatomy of the lung.
  • Taking into account the anatomical variant of the vessels is important to avoid mistakes.
  • The uniportal VATS approach provides to the thoracic surgeon the flexibility to perform bilateral segmentectomies in a single stage surgical procedure.
