Thoracoscopic excision of asymptomatic posterior mediastinal ganglioneuroma. A case series study
Background
Posterior mediastinal ganglioneuroma is the most frequent type of neurogenic tumors, and usually it is asymptomatic. The surgical approach to excise it may differ from center to center based on the surgeon's experience as well as the size of tumor. We aim to present our center's experience and short-term outcomes in surgical excision of posterior mediastinal ganglioneuroma.
Methods
This retrospective case series study, from June 2019 till December 2022, included 9 asymptomatic patients with mean age of 31± 5 years who expressed lesion in the posterior mediastinum. The mean size of the tumor was 5.3±3.6 cm in maximal dimensions.
Results
There were 7 males and 2 females with mean age was 31± 5 years, the excision by video-assisted thoracoscopy (VATS) was employed in 8 patients and conventional thoracotomy was carried out in 1 case. The mean operative time was 57±14 minutes with mean operative blood loss 50±10 ml. The mean postoperative chest tube drainage was 120±80 ml and no complications related to the procedures were observed. The average time of hospital stay after VATS treatment was 2 days, while after thoracotomy it was 5 days and patient suffered from ptosis that eventually recovered after 1 month with supportive treatment. Histopathological examination confirmed benign nature of ganglioneuroma in all cases.
Conclusions
Thoracoscopic excision of asymptomatic posterior mediastinal neurogenic tumor is safe, feasible and reduces postoperative pain, however, open technique might be considered for large-sized tumor to minimize the possible complications
Can a foreign body migrate against natural body barriers?
Pericardial foreign bodies (FBs) are a rare cause of chest pain in children. They can reach the pericardium through several routes including direct or iatrogenic implantation, transbronchial or transesophageal migration of inhaled or swallowed FBs. We reported a case of a 4-year-old girl presenting with persistent chest pain for 1 month. The child described the pain as ‘stitching’ in nature localized on the left side of the sternum. The child presented with increased pain intensity and a new onset of fever and cough. No history of chocking or swallowing of FB and no signs of trauma or child abuse were noted. Chest radiography revealed a needle in the left side of the chest. Computed tomography scan and echocardiography were used to precisely localize the needle and exclude intracardiac extension. ECG showed elevated ST segment and cardiac enzymes were normal. Removal of the needle was carried out surgically under fluoroscopic guidance. A small portion of the needle was found intrapericardially complicated by localized purulent pericarditis. The child had uneventful recovery and was discharged from the hospital on postoperative day 3.Keywords: foreign bodies, pain, pediatrics, pericardium, thoracic surger

Spontaneous versus mechanical ventilation during video-assisted thoracoscopic surgery for spontaneous pneumothorax: a randomized trial
Objective: Spontaneous ventilation video-assisted thoracic surgery (SV-VATS) is reported to have superior or equal efficacy on postoperative recovery to mechanical ventilation VATS (MV-VATS). However, perioperative safety of the SV-VATS blebectomy is not entirely demonstrated.
Methods: We performed a noninferiority, randomized controlled trial (No. NCT03016858) for primary spontaneous pneumothorax patients aged 16 to 50 years undergoing a SV-VATS and the MV-VATS procedure. The trial was conducted at 10 centers in China from April 2017 to January 2019. The primary outcome was the comparison of intra- and postoperative complications between SV-VATS and MV-VATS procedures. Secondary outcomes included total analgesia dose, change of vital sign during surgery, procedural duration, recovery time, postoperative visual analog pain scores, and hospitalization length.
Results: In this study, 335 patients were included. There was no significant difference between the SV-VATS group and the MV-VATS group in the intra- and postoperative complication rates (17.90% vs 22.09%; relative risk, 0.81; 95% confidence interval, 0.52-1.26; P = .346). The SV-VATS group was associated with significantly decreased total dose of intraoperative opioid agents; that is, sufentanil (11.37 μg vs 20.92 μg; P < .001) and remifentanil (269.78 μg vs 404.96 μg; P < .001). The SV-VATS procedure was also associated with shorter extubation time (12.28 minutes vs 17.30 minutes; P < .001), postanesthesia care unit recovery time (25.43 minutes vs 30.67 minutes; P = .02) and food intake time (346.07 minute vs 404.02 minutes; P = .002). Moreover, the SV-VATS procedure deceased the anesthesia cost compared with the MV-VATS (399.81; P < .001).
Conclusions: SV-VATS was shown to be noninferior to MV-VATS in term of complication rate and in selected patients undergoing blebectomy for primary spontaneous pneumothorax
Post-Vasectomy Semen Analysis: Optimizing Laboratory Procedures and Test Interpretation through a Clinical Audit and Global Survey of Practices
Purpose: The success of vasectomy is determined by the outcome of a post-vasectomy semen analysis (PVSA). This article describes a step-by-step procedure to perform PVSA accurately, report data from patients who underwent post vasectomy semen analysis between 2015 and 2021 experience, along with results from an international online survey on clinical practice.
Materials and methods: We present a detailed step-by-step protocol for performing and interpretating PVSA testing, along with recommendations for proficiency testing, competency assessment for performing PVSA, and clinical and laboratory scenarios. Moreover, we conducted an analysis of 1,114 PVSA performed at the Cleveland Clinic's Andrology Laboratory and an online survey to understand clinician responses to the PVSA results in various countries.
Results: Results from our clinical experience showed that 92.1% of patients passed PVSA, with 7.9% being further tested. A total of 78 experts from 19 countries participated in the survey, and the majority reported to use time from vasectomy rather than the number of ejaculations as criterion to request PVSA. A high percentage of responders reported permitting unprotected intercourse only if PVSA samples show azoospermia while, in the presence of few non-motile sperm, the majority of responders suggested using alternative contraception, followed by another PVSA. In the presence of motile sperm, the majority of participants asked for further PVSA testing. Repeat vasectomy was mainly recommended if motile sperm were observed after multiple PVSA's. A large percentage reported to recommend a second PVSA due to the possibility of legal actions.
Conclusions: Our results highlighted varying clinical practices around the globe, with controversy over the significance of non-motile sperm in the PVSA sample. Our data suggest that less stringent AUA guidelines would help improve test compliance. A large longitudinal multi-center study would clarify various doubts related to timing and interpretation of PVSA and would also help us to understand, and perhaps predict, recanalization and the potential for future failure of a vasectomy
Burnout among surgeons before and during the SARS-CoV-2 pandemic: an international survey
Background: SARS-CoV-2 pandemic has had many significant impacts within the surgical realm, and surgeons have been obligated to reconsider almost every aspect of daily clinical practice. Methods: This is a cross-sectional study reported in compliance with the CHERRIES guidelines and conducted through an online platform from June 14th to July 15th, 2020. The primary outcome was the burden of burnout during the pandemic indicated by the validated Shirom-Melamed Burnout Measure. Results: Nine hundred fifty-four surgeons completed the survey. The median length of practice was 10 years; 78.2% included were male with a median age of 37 years old, 39.5% were consultants, 68.9% were general surgeons, and 55.7% were affiliated with an academic institution. Overall, there was a significant increase in the mean burnout score during the pandemic; longer years of practice and older age were significantly associated with less burnout. There were significant reductions in the median number of outpatient visits, operated cases, on-call hours, emergency visits, and research work, so, 48.2% of respondents felt that the training resources were insufficient. The majority (81.3%) of respondents reported that their hospitals were included in the management of COVID-19, 66.5% felt their roles had been minimized; 41% were asked to assist in non-surgical medical practices, and 37.6% of respondents were included in COVID-19 management. Conclusions: There was a significant burnout among trainees. Almost all aspects of clinical and research activities were affected with a significant reduction in the volume of research, outpatient clinic visits, surgical procedures, on-call hours, and emergency cases hindering the training. Trial registration: The study was registered on clicaltrials.gov "NCT04433286" on 16/06/2020
Nonintubated Subxiphoid Bilateral Redo Lung Volume Reduction Surgery
This report describes a nonintubated, bilateral thoracoscopic redo lung volume reduction surgery procedure through a single subxiphoid access in a patient who previously underwent one-stage bilateral volume reduction for upper lobe-predominant heterogeneous emphysema 19 years earlier. The patient was uneventfully discharged on postoperative day 2, and meaningful improvement in respiratory function and exercise tolerance occurred at 3 months postoperatively. This novel surgical approach may merge the potential benefits of a subxiphoid incision for bilateral treatment, non-intercostal passage of chest drains, and adoption of a nonintubated anesthesia protocol.

A new method of infrared-fluorescence-enhanced thoracoscopic segmentectomy.
Optimal identification of the intersegmental plane can be challenging during thoracoscopic anatomical segmentectomy for lung cancer. We describe a simple new method of infrared-fluorescence-enhanced thoracoscopy with selected injection of indocyanine green into the bronchi not targeted for resection, which allows us to clearly identify the intersegmental plane in thoracoscopic segmentectomy
