The 100 most-cited articles on pectus deformities: A bibliometric analysis.

BACKGROUND: In this study, we aimed to examine the development of knowledge on pectus deformities through a meticulous analysis of the 100 most-cited articles published on this topic. METHODS: Publications related to pectus deformities from January 1975 to April 2020 were scanned using the Web of Science Core Collection database. The publications were ranked from maximum to minimum according to the number of citations and were examined in detail. RESULTS: The 100 articles were published in 27 different journals and received a total of 8,290 citations. The average of the impact factors of journals in 2018 was 4.441. The mean citation density of all articles was 5.1±3.8. In the past years, a surgical technique definition and experience transfer were more frequently used, while complications and technical details were started to be presented in recent years. CONCLUSION: Our study results suggest that the studies of pectus deformities would continue and, from now on, issues such as complications and technical details would come to the forefront in the articles.

A different approach in thoracic surgery: Guillotine lobectomy.

BACKGROUND: In this study, we aimed to compare the surgical results of video-assisted thoracoscopic lobectomy with the guillotine technique to the results of conventional video-assisted thoracoscopic lobectomy. METHODS: Between January 2013 and December 2019, a total of 49 patients (20 males, 29 females; median age: 45 years; range, 11 to 73 years) who underwent video-assisted thoracoscopic lobectomy for benign lung pathologies were retrospectively analyzed. The patients were divided into two groups: the guillotine technique group (n=31) who had simultaneous cutting of the lobar artery and lobar bronchus with a single stapler, and the control group (n=18) who received conventional video-assisted thoracoscopic lobectomy. Demographic features of the patients, type of surgery, type of pulmonary resection, duration of the operation, postoperative length of hospital stay, postoperative pathological examination result, complications, and follow-up data were recorded. RESULTS: The median operation time was 142.5 (range, 60 to 237) min and 90 (range, 55 to 180) min in the control and the guillotine technique groups, respectively, indicating a statistically significant difference (p<0.05). Bronchiectasis was the most common histopathological diagnosis in both groups. No intraoperative complication, long-term complications or mortality were observed in any of the patients. CONCLUSION: The guillotine lobectomy technique significantly reduces the duration of the operation. The adventitia and connective tissue around the lobar artery and lobar bronchus enable the closure of these structures with the supporting tissue and, therefore, reinforces the staples. The guillotine technique in video-assisted thoracoscopic lobectomy seems to be a cost-effective, reliable, and practical method that provides intraoperative convenience and shortens the operation time.

The effect of pectus excavatum deformity on lung volume: fact or myth?

BACKGROUND AND PURPOSE: Most of the previous studies evaluating lung volume of pectus excavatum (PE) patients were based on spirometric measurements. We aimed to calculate lung volume of patients with PE and compare them with lung volume of patients without chest wall deformity using CT volumetry. METHODS: After institutional review board approval, preoperative chest CT of PE patients who underwent minimal invasive procedure between January 2012 and February 2018, were evaluated retrospectively. As a control group, age and sex matched patients who underwent chest CT scan in the same period were enrolled. Total, right and left lung volumes were calculated using an automated software. Haller indexes were measured for both groups. Lung volumes and Haller indexes compared between the two groups. We also compared left and right lung volumes in both groups. We evaluated whether there is a correlation across the Haller index and total lung volume. RESULTS: Total, right and left lung volumes were not statistically different between the two groups. While left lung volumes were significantly smaller in PE group (p = 0.041), there was no significant difference between the left and right lung volume in the control group (p = 0.12). Haller index and total lung volume showed no significant correlation between patients with the same age and gender (p = 0.14, R = -0.3). CONCLUSIONS: PE deformity does not reduce lung volume when compared to age and sex matched control group. Quantitative CT volumetric evaluation of lung gives valuable data about lung volume.

Trust the Capitonnage in the Giant Cyst: Case Report.

Cyst hydatid in the lung is still a health problem for many countries. It develops in the lung and can grow into the lung parenchyma. When it is diagnosed as a giant cyst, surgery should be performed. In the surgery, capitonnage is necessary to protect the lung parenchyma.

Use of Magill Forceps to Remove Foreign Bodies in Children.

Introduction Esophageal foreign body (FB) in all age groups can cause serious morbidity or mortality. The study aims to report our experience retrieving FBs from the upper esophagus in children using Magill forceps. Materials and Methods In this study, 88 patients (45 males [51.1%] and 43 females [48.9%]) were presented with suspected FB ingestion. FB ingestion was determined via endoscopic analysis, or lateral and posterior-anterior radiographies, including oropharynx, neck, chest, and abdomen. Cases were classified into seven groups, according to history, diagnostic method, and postintervention findings, as follows: (1) coins, (2) toys, (3) metals, (4) bones, (5) battery, (6) glass, and (7) food. A laryngoscope was used to elevate the larynx and expose the esophageal entrance. Magill forceps were advanced into the esophagus and opened to observe and extract the FB. Results All 88 patients who underwent endoscopic examination due to suspected FB ingestion were confirmed to have ingested a FB. Median age was 12 years; 15 patients were aged < 5 years; 63 (71.5%) were diagnosed based on routine radiographic findings, and others were diagnosed based on physical findings and history. The most common type of FB was coins ( n = 51 [57.9%]). Mean surgical duration was 20 minutes. Conclusion FBs located at cervical esophageal level are usually the most difficult to remove. Magill forceps should be used before other methods.

Increased ischemia-modified albumin and malondialdehyde levels in videothoracoscopic surgery.

BACKGROUND: Videothoracoscopic surgery leads to general organ hypoperfusion by reducing mean arterial pressure, systemic vascular resistance, and end-diastolic volume index. Oxidative stress occurs as a result of hypoperfusion. Evaluation of the short-term effects of videothoracoscopic sympathectomy on serum ischemia-modified albumin (IMA), malondialdehyde (MDA), and nitric oxide (NO) levels in patients with primary hyperhidrosis was aimed. METHODS: Twenty-six patients who underwent videothoracoscopic surgery were contributed in this study. Venous blood samples were obtained from these patients 1 h before and after the surgery. IMA, MDA, and NO levels were measured in serum samples by colorimetric methods. Albumin concentrations were also measured for each sample, and albumin-adjusted IMA levels were calculated. RESULTS: Postoperative IMA, albumin-adjusted IMA, and MDA values were significantly higher compared to the preoperative values (P = 0.003, 0.027, 0.018, respectively). However, postoperative NO levels were lower than the preoperative values (P = 0.002). There was no significant difference between pre- and postoperative albumin concentrations, and there was no significant correlation between the parameters tested. CONCLUSIONS: We can conclude that elevation in MDA and IMA levels after videothoracoscopic surgery was caused by increased oxidative stress due to minimal ischemia-reperfusion injury after the infusion of CO2 during the surgical process. Videothoracoscopic sympathectomy operation causes a decrease in NO production, and this should be taken in consideration when evaluating nitrosative stress in videothoracoscopic surgery.
