Abstract Background The aim of the study is to evaluate the feasibility, safety, and effectiveness of preoperative computed tomography (CT)-guided trans-scapular coil localization (TSCL) of scapula-blocked pulmonary nodules (PNs). Methods Between November 2015 and May 2020, 11 patients underwent preoperative CT-guided TSCL procedures owing to PN occlusion by scapula. Results A 100% technical success rate was achieved for CT-guided TSCL, with one coil being used for each PN. One patient (9.1%) developed pneumothorax. Successful video-assisted thoracoscopic surgery (VATS)-guided wedge resection of these scapula-blocked PNs was conducted in all patients. Conclusion CT-guided TSCL can be simply and safely used to facilitate successful VATS-guided wedge resection of scapula-blocked PNs.

Abstract Background: Preoperative computed tomography (CT)-guided coil localization (CL) is commonly employed to facilitate the video-assisted thoracoscopic surgery (VATS)-guided diagnostic wedge resection (WR) of pulmonary nodules (PNs). When a scapular-blocked PN (SBPN) will be localized, the trans-scapular CL (TSCL) should be performed. In this study, we investigated the safety, feasibility, and clinical efficacy of preoperative CT-guided TSCL for SBPNs.Materials and Methods: From January 2014 to September 2020, a total of 152 patients with PNs underwent CT-guided CL prior to VATS-guided WR. Among them, 14 patients had the SBPNs and underwent TSCL procedure. Results: A total of 14 SBPNs were localized in the 14 patients. The mean diameter of the 14 SBPNs was 7.4 ± 2.4 mm. Technical success rate of puncture of the scapula was 100%. No complications occurred near the scapula. Technical success rate of CL was 92.9%. One coil dropped off when performing the VATS procedure. The mean duration of the TSCL was 14.2 ± 2.7 min. Two patient (14.3%) developed aysmptomatic pneumothorax after TSCL. Technical success rate of VATS-guided WR was 92.9%. The patient who experienced technical failure of TSCL directly underwent lobectomy. The mean VATS procedure duration and blood loss were 90.0 ± 42.4 min and 62.9 ± 37.2 ml, respectively. The final diagnoses of the 14 SBPNs included invasive adenocarcinoma (n = 4), adenocarcinoma in situ (n = 9), and benign (n = 1).Conclusions: Preoperative CT-guided TSCL can be safely and simply used to facilitate high successful rates of VATS-guided WR of SBPNs.

Excessive Accumulation

Pulmonary alveolar proteinosis (PAP) is a rare pulmonary condition which leads to excessive accumulation of proteinaceous material within the alveoli. Idiopathic pulmonary haemosiderosis (IPH) is another orphan lung disease and results in recurrent alveolar haemorrhage. This case study describes a case of these two rare pathologies occurring together. A man in his 50s presented with a 6-week history of haemoptysis and worsening dyspnoea. A CT scan of the thorax showed multifocal, bilateral ground glass opacification with a wide differential diagnosis. Full autoantibody screen including myositis panel and coeliac screen were negative. Bronchoscopy with bronchoalveolar lavage and tissue from a transbronchial lung cryobiopsy were non-diagnostic. Tissue from a video-assisted thoracoscopic surgery biopsy confirmed a diagnosis of PAP with IPH as a second separate pathology. The association of IPH and PAP has not previously been described. We discuss these conditions and postulate how and if they may be related.

Abstract Various marking techniques for lung nodules may be complex and can cause serious complications. In this study, we aimed to describe and evaluate the feasibility of CTFRC marking, a novel preoperative skin marking technique guided by computed tomography (CT) at functional residual capacity (FRC). This simple and non-invasive marking technique only requires a preoperative CT scan without any anaesthesia. We retrospectively reviewed CTFRC markings performed for 109 lung nodules in 108 patients. The mean nodule size was 11.4 ± 5.0 mm. The mean distance from the nodule to the lung marking point was 3.8 ± 7.3 mm. We found no procedure-associated complications. CTFRC marking is a simple, safe and non-invasive method to predict the precise location of lung nodules during thoracoscopic surgery.

AbstractUsing interviews with former militants and previously unpublished documents, this article traces the genesis and internal dynamics of the Ejército Revolucionario del Pueblo (People's Revolutionary Army, ERP) in El Salvador during the early years of its existence (1970–6). This period was marked by the inability of the ERP to maintain internal coherence or any consensus on revolutionary strategy, which led to a series of splits and internal fights over control of the organisation. The evidence marshalled in this case study sheds new light on the origins of the armed Salvadorean Left and thus contributes to a wider understanding of the processes of formation and internal dynamics of armed left-wing groups that emerged from the 1960s onwards in Latin America.
