23. Is It Time to (Re)define the N‐Category for Metastatic Lymph Nodes in Non–Small Cell Lung Cancer?

Author

Verkoulen, Koen C. H. A., Daemen, Jean H. T., Franssen, Aimée J. P. M., Degens, Juliette H. R. J., Hulsewé, Karel W. E., Vissers, Yvonne L. J., and de Loos, Erik R.

Abstract

The article in the Clinical Respiratory Journal by Guo et al. explores the relationship between the number and rate of resected metastatic lymph nodes and survival in patients with non-small cell lung cancer (NSCLC). The study suggests that both the number and rate of positive lymph nodes are predictors of overall survival, regardless of the nodal station affected. However, the findings are limited to postoperative patients who underwent lymphadenectomy with complete lymph node dissection. The study highlights the challenges in defining the N-category for TNM staging and emphasizes the need for more uniform guidelines and clarity in lymph node staging practices.

24. Scapula alata, a rare complication after minimally invasive repair of pectus excavatum.

Author

Laven, Iris E. W. G., van Polen, Elise J., Vissers, Yvonne L. J., and de Loos, Erik R.

Abstract

A male patient in his early 30s underwent minimally invasive repair of pectus excavatum. According to standard Nuss bar procedure, a 30-degree thoracoscope was introduced through a right midaxillary 10 mm trocar in the 4th intercostal space. Two bars and five stabilisers were placed in a retromuscular position. After discharge, the patient experienced right upper back pain requiring prolonged opioid usage for threemonths and right scapular winging limiting functional activities. After conservative treatment with physiotherapy for 11 months, the patient still suffered from residual scapula alata with pain and muscle weakness. On suspicion of long thoracic nerve neuropraxia related to the thoracoscope placement, an electromyogram was conducted 16 months following surgery, revealing mild polyphasic potentials of the serratus anterior muscle without abnormal muscle unit action potential. After extended conservative therapy for another year, physical examination 28 months after surgery showed almost complete resolution of scapular winging. [ABSTRACT FROM AUTHOR]

35. Predicting Aesthetic Outcome of the Nuss Procedure in Patients with Pectus Excavatum

Abstract

Patients suffering from pectus excavatum often experience psychosocial distress due to perceived anomalies in their physical appearance. The ability to visually inform patients about their expected aesthetic outcome after surgical correction is still lacking. This study aims to develop an automatic, patient-specific model to predict aesthetic outcome after the Nuss procedure. Patients prospectively received preoperative and postoperative 3-dimensional optical surface scanning of their chest during the Nuss procedure. A prediction model was composed based on nonlinear least squares data-fitting, regression methods and a 2-dimensional Gaussian function with adjustable amplitude, variance, rotation, skewness, and kurtosis components. Morphological features of pectus excavatum were extracted from preoperative images using a previously developed surface analysis tool to generate a patient-specific model. Prediction accuracy was evaluated through cross-validation, utilizing the mean root squared deviation and maximum positive and negative deviations as performance measures. The prediction model was evaluated on 30 (90% male) prospectively imaged patients. The model achieved an average root mean squared deviation of 6.3 ± 2.0 mm, with average maximum positive and negative deviations of 12.7 ± 6.1 and -10.2 ± 5.7 mm, respectively, between the predicted and actual postoperative aesthetic result. Our developed 2-dimensional Gaussian model based on 3-dimensional optical surface images is a clinically promising tool to predict postsurgical aesthetic outcome in patients with pectus excavatum. Prediction of the aesthetic outcome after the Nuss procedure potentially improves information provision and expectation management among patients. Further research should assess whether increasing the sample size may reduce deviations and improve performance.

Abstract

Pectus excavatum is the most common congenital anterior chest wall deformity. Currently, a wide variety of diagnostic protocols and criteria for corrective surgery are being used. Their use is predominantly based on local preferences and experience. To date, no guideline is available, introducing heterogeneity of care as observed in current daily practice. The aim of this study was to evaluate consensus and controversies regarding the diagnostic protocol, indications for surgical correction, and postoperative evaluation of pectus excavatum. The study consisted of 3 consecutive survey rounds evaluating agreement on different statements regarding pectus excavatum care. Consensus was achieved if at least 70% of participants provided a concurring opinion. All 3 rounds were completed by 57 participants (18% response rate). Consensus was achieved on 18 of 62 statements (29%). Regarding the diagnostic protocol, participants agreed to routinely include conventional photography. In the presence of cardiac impairment, electrocardiography and echocardiography were indicated. Upon suspicion of pulmonary impairment, spirometry was recommended. In addition, consensus was reached on the indications for corrective surgery, including symptomatic pectus excavatum and progression. Participants moreover agreed that a plain chest radiograph must be acquired directly after surgery, whereas conventional photography and physical examination should both be part of routine postoperative follow-up. Through a multiround survey, international consensus was formed on multiple topics to aid standardization of pectus excavatum care. [ABSTRACT FROM AUTHOR]

Abstract

Background: Surgical stabilization of rib fractures (SSRF) is associated with improved respiratory symptoms and shorter intensive care admission in patients with flail chest. For multiple rib fractures, the benefit of SSRF remains a topic of debate. This study investigated barriers and facilitators of healthcare professionals to SSRF as treatment for multiple traumatic rib fractures. Methods: Dutch healthcare professionals were asked to complete an adapted version of the Measurement Instrument for Determinants of Innovations questionnaire to identify barriers and facilitators of SSRF. If ≥ 20% of participants responded negatively, the item was considered a barrier, and if ≥ 80% responded positively, the item was considered a facilitator. Results: Sixty-one healthcare professionals participated; 32 surgeons, 19 non-surgical physicians, and 10 residents. The median experience was 10 years (P25–P75 4–12). Sixteen barriers and two facilitators for SSRF in multiple rib fractures were identified. Barriers included lack of knowledge, experience, evidence on (cost-)effectiveness, and the implication of more operations and higher medical costs. Facilitators were the assumption that SSRF alleviates respiratory problems and the feeling that surgeons are supported by colleagues for SSRF. Non-surgeons and residents reported more and several different barriers than surgeons (surgeons: 14; non-surgical physicians: 20; residents: 21; p < 0.001). Conclusion: For adequate implementation of SSRF in patients with multiple rib fractures, implementation strategies should address the identified barriers. Especially, improved clinical experience and scientific knowledge of healthcare professionals, and high-level evidence on the (cost-) effectiveness of SSRF potentially increase its use and acceptance.
