Abstract
INTRODUCTION Neurogenic tumours are the most common tumours of the posterior mediastinum and account for 75% of the tumours in this region. Till recently, open transthoracic approach has been the standard of care for their excision. Thoracoscopic excision of these tumours is being commonly employed because of lesser morbidity and shorter hospital stay. The robotic surgical system offers a potential advantage over conventional thoracoscopy. We herein report our technique and surgical outcomes of excision of posterior mediastinal tumours using the Da Vinci Robotic Surgical System. MATERIALS AND METHODS We retrospectively reviewed 20 patients who underwent Robotic Portal-Posterior Mediastinal Tumour (RP-PMT) Excision at our centre. The demographic data, clinical presentation, characteristics of the tumour, operative and post-operative variables including, total operative time, blood loss, conversion rate, duration of the chest tube, hospital stay and complications were noted. RESULTS Twenty patients underwent RP-PMT Excision and were included in the study. The median age was 41.2 years. The most frequent presentation was chest pain. Schwannoma was the most common histopathological diagnosis. There were two conversions. The total operative time was 110 min with an average blood loss of 30 mL. Two patients developed complications. The postoperative hospital stay was 2.4 days. With a median follow-up of 36 months (6-48 months), all except patients are recurrence-free, except the patient with malignant nerve sheath tumour who developed local recurrence. CONCLUSION Our study demonstrates the feasibility and safety of robotic surgery for posterior mediastinal neurogenic tumours with good surgical outcomes.

Abstract
BACKGROUND This study aimed to report the surgical outcomes and also evaluating the safety and feasibility of thoracoscopic pericardial window (PW) for recurrent pericardial effusion. MATERIALS AND METHODS This was a retrospective analysis of eight cases of recurrent pericardial effusion, managed by thoracoscopic method in a tertiary-level thoracic surgery centre over 5 years. A detailed analysis of all perioperative variables, including complications, was carried out. RESULTS A total of eight patients underwent thoracoscopic PW during the study period. Males (87.5%) were predominant in the cohort. The median age was 54 years (range: 28-78 years). The median duration of symptoms was 2 months (range: 1-3 months). Tuberculosis (50%), malignancy (37.5%) and chronic kidney disease (12.5%) were the causes of recurrent effusion. All patients underwent thoracoscopic procedure with no conversions. The median operative time was 45 min (range: 40-70 min). The median effusion volume drained was 500 ± 100 ml. The median hospital stay was 3 days (range: 2-4 days) with no post-procedural complications. All the patients had complete resolution of symptoms. No recurrence was noted in the median follow-up period of 28 months (range: 6-60 months). CONCLUSIONS Thoracoscopic PW is a safe and feasible minimally invasive option in the management of recurrent pericardial effusion in selected patients. Surgical fitness, haemodynamic status and estimated survival (in malignant effusion) should be considered before the procedure.

Abstract
The scientists compared the outcomes of a minimally invasive operation approach (MIO) to a conventional poster lateral (PL) method in overall hip replacement (OHR) in terms of itchiness, damage to muscles, and bleeding. The factors that researchers examined were the levels of Haemoglobin (Hg), a marker for oxygen depletion, the quantity of Interleukin-6 (IL6), a marker for inflammation, the heart-type fatty acid binding protein (HTFABP), and the health of the muscles. The study's findings showed that IL6 content increased beyond pre-operative levels as a result of the two surgeries. At 6 hours after surgery, the mean IL6 concentration in the PL group was 79.6 pg/ml while in the MIO group it was 76.4 pg/ml. The highest values after 24 hours of therapy were 100 pg/ml in the PL group and 92.3 pg/ml in the MIO category. In each category, IL6 levels had dropped up to this point. The post-operative mean HTFABP concentration in the MIO organization was greater (12.5 mg/l) than in the PL organization (18.3 mg/l) in terms of muscle damage. One day after surgery, however, it reached an apex and began to decline in both groups. The amounts of Hg lost throughout the procedure decreased for both sets. 12.5 g/dl of mercury was present. The MIO grouping had PL 72 hours following a procedure, while the PL grouping had 10.3 g/dl. Between the two surgical methods, there were no obvious differences in bleeding, muscle damage, or edema. These results led the researchers to draw the conclusion that there were little differences between the MIO anterior method and the traditional PL technique in terms of muscle damage, blood loss, or irritability. The lack of a learning curve in the study may account for the lack of alterations seen, they hypothesized, rendering the use of the term "MIO" in describing the approach as less traumatizing dubious. The study's methodology, sample sizes, and all other relevant material were left out, making it impossible to evaluate the study's validity and generalizability in its entirety.

Abstract
This study aims to characterize and contrast the triennial rates at which doctors prescribe PT, determine patient, doctor, and practicing characteristics related to every therapy suggestion, and assess pain relievers, lifestyle counseling, and PT as effective treatments for knee osteoarthritis (OA). We analyzed the National Ambulatory Medical Care Survey. Nonsteroidal anti-inflammatory drugs (NSAID), narcotics prescriptions, physical therapy referrals, and primary care physician visits for knee OA have been determined and evaluated. The average yearly rate after three years of therapy was determined. Using multivariable logistic modeling with adjustments for complicated sample design, we analyzed the relationships among patient, physician, and practice characteristics and treatments. Over time the patients were prescribed physical therapy to improve their lifestyle whereas the percentage of patients who were prescribed NSAIDs or drugs. Physical therapy, lifestyle therapy, and drugs were prescribed at similar rates across time for basic care doctor visits. There was an association between nonclinical characteristics and treatment suggestions, such as provider type, practice setting, and geographic proximity. Physical therapy (PT) and lifestyle counseling (LC) seem underused in patients with knee OA, but prescriptions for pain medication rose over the studied period. The treatment decisions varied due to variables outside of medicine. Increased usage of physical therapy and lifestyle changes, as well as decreased treatment variance for knee OA, are important areas for further study.

Abstract
We present herein our results of cricoid augmentation with costal cartilage in complex crico-tracheal stenosis in adults. This is a retrospective analysis of a prospectively maintained data of patients who underwent surgery for crico-tracheal stenosis at a tertiary care centre from March 2012 to September 2019. Finding of subglottic stenosis with cricoid narrowing was taken as an indication for cricoid split and costal cartilage graft augmentation. Their demographic and clinical data, pre-operative work up, intra-operative details and post-operative course was recorded. Ten patients underwent cricoid split with costal cartilage graft augmentation and crico-tracheal anastomosis between March 2012 and November 2019. The mean age was 29 years (range, 22-58 years). There were 6 males (60%) and 4 females (40%). All 10 patients underwent circumferential resection of stenosed tracheal segment, cricoid split, interposition of costal cartilage graft and an anastomosis between augmented cricoid and trachea. Eight patients (80%) anterior cricoid split and 2 (20%) had anterior as well as posterior split. Average resected length of trachea was 2.39 cms. Cricoid split with costal cartilage augmentation is a feasible option to expand cricoid lumen in crico-tracheal stenosis. None except one of our patients required any further intervention in mean follow up of 42 months and all are free from primary symptoms. The functional results of the surgery were also excellent in 90% of the patients.

Abstract
OBJECTIVES This study aims at reporting the surgical outcomes of COVID associated pulmonary mucormycosis with special emphasis on surgical mortality. METHODS This prospective observational study was conducted in a dedicated thoracic surgical unit in Gurugram, India over 18 months. An analysis of demography, peri-operative variables were carried out. Various parameters were analysed to assess the factors affecting mortality. RESULTS Total of 44 patients with diagnosis of CAPM were managed during the study period. All were started on anti-fungal therapy. However, 33 patients (75%) were operated whereas rest 11 (25%) were not considered suitable for surgery. In the surgical cohort (n = 33), there were 20 males (60.6%) and 13 females (39.4%), with a mean age of 54.8 years (range, 33-72 years). The mean duration of the symptoms was 1.1 weeks. Non-anatomical wedge resection of lobe(s) was performed in 5 patients (15.1%), lobectomy/bi-lobectomy was required in 26 patients (78.9%) and left pneumonectomy in 2 patients (6%). There were 5 peri-operative deaths (15.1%), all due to fungal sepsis. ECOG scale > 2 (P ≤ 0.001), higher Charlson Comorbidity Index score > 2 (P = 0.04) and pneumonectomy (P = 0.02) were the predictors of mortality. On comparison with NCPM, there was no difference in the incidence of post-operative complications (P = 0.50) and the post-operative mortality (P = 0.69). CONCLUSION Aggressive surgical resection with clear margins should be offered in CAPM, whenever feasible. Surgery for CAPM was not associated with higher post-operative complications including mortality compared to Non-COVID Pulmonary Mucormycosis.

Abstract
Background: This study describes the surgical technique of thoracoscopic resection of posterior mediastinal neurogenic tumours and reporting the surgical outcomes. Methods: This is a retrospective analysis of 21 patients operated over 7 years in a dedicated thoracic surgery centre. The demographic and post-operative parameters along with complications were recorded and analysed. Results: Twelve patients had right-sided tumours, while 9 had left-sided lesions, and 9 were on the left side. The most common diagnosis was schwannoma (n = 15, 71.42%), followed by neurofibroma (n = 4, 19.04%). The average surgery duration was 104 min (85–135 min), and the mean blood loss was 120 ml (25 ml–250 ml). The average lesion size was 4.8 cm (2 cm–7 cm). Conversion to open procedure was required in one patient. Two patients (14.2%) developed complications. One patient developed Horner's Syndrome and the other developed post-operative lung atelectasis. The median follow-up was 36 months (6–90 months). No recurrence was observed during the follow-up period. Conclusions: Thoracoscopic approach to posterior mediastinal neurogenic tumours is feasible and allows for low morbidity, short hospital stay and superior cosmesis.

Abstract
Background The present study aims to report the outcomes of a multidisciplinary, minimally invasive approach to treating patients with delayed presentation of oesophageal perforation. Patients and Methods The present study is a retrospective analysis of prospectively maintained data at a tertiary care centre. All patients with oesophageal perforation presenting over 48 h after the onset of symptoms and without oesophageal obstruction were included in the study. Self-expanding Metallic Stent (SEMS) or endoscopic clip placement was performed in all the patients, followed by video-assisted thoracoscopic surgery (VATS) debridement and decortication of pleural cavity collection. 'Success' was defined as, discharge without the need of oesophageal diversion and complete healing of leak site at 8 weeks with successful removal of the stent. Results Between March 2012 and December 2019, 12 patients (10 males, median age of 55 years- range of 39-71 years) with oesophageal perforation and delayed presentation underwent treatment with this approach. Ten patients had spontaneous perforation (83.3%) and one patient each had upper gastrointestinal endoscopy-induced and post-traumatic perforation. The median duration of symptoms was 8 days (range 3-31 days). SEMS was placed in ten patients and, in two patients, an over-the-scope clip was used. VATS decortication was done in ten patients (83.3%) and the remaining two (16.7%) underwent VATS debridement. One patient required oesophageal diversion and another patient expired due to sepsis. The overall success with this approach was 83.3%. Conclusion This multidisciplinary, minimally invasive approach is feasible in patients with thoracic oesophageal perforation and delayed presentation, with a high success rate.

Abstract
Introduction: Complete enucleation of oesophageal leiomyoma is the treatment of choice, traditionally performed by open surgery. Minimally invasive thoracoscopic approaches have been proposed as an alternative to thoracotomy. Robotic surgical systems with improved dexterity, tremor filtration and stereoscopic vision are advancement over conventional thoracoscopy and may make the preservation of mucosal integrity relatively easier. We present herein our technique of robotic-assisted thoracoscopic (RATS) enucleation of oesophageal leiomyoma along with surgical outcomes and intermediate follow-up of 11 cases. Materials and Methods: The present study retrospectively reviews patients undergoing robotic portal oesophageal leiomyomectomy from March 2012 to October 2019. The collected data were analysed for demographic details, clinical presentation, size, shape, tumour location, operating time, post-operative complications, length of hospital stay and recurrence on follow-up. Results: Twelve patients underwent robotic portal oesophageal leiomyomectomy with a clinical diagnosis of oesophageal leiomyoma. Of these, 11 patients were included in the study. The average operative time was 110 min, with a mean blood loss of 26 ml. There was no conversion in this series. At a median follow-up of 44 months (range 6–78 months), all patients were symptom-free with no recurrence or diverticula. Conclusion: Our series demonstrates the safety and feasibility of RATS oesophageal enucleation with good short and intermediate outcomes. In our opinion, the robotic system's technical advantages are particularly beneficial for oesophageal leiomyoma enucleation.

Abstract
Background Few studies have compared the surgical outcomes between tubercular empyema (TE) and nontubercular empyema (NTE), which were limited by a small sample size. We conducted this study with the objective of comparing the surgical outcomes of patients with tuberculous and nontuberculous empyema. Materials and Methods This is a retrospective analysis of 285 consecutively operated cases of TE and NTE over 5 years conducted in a tertiary care center in New Delhi, India. A comparative analysis of demography, intraoperative, and postoperative variables including mortality between the two groups was carried out. Results Out of 285 patients, 166 were tubercular and 119 were nontubercular. Nontubercular group had significantly higher age (45.4 ± 17.2 vs. 31.2 ± 13.6 in years), more comorbidities. Procedure was started by thoracotomy in 25.9% of tubercular group and 41.1% of nontubercular group. In patients where procedure started by video-assisted thoracoscopic surgery (VATS), complete decortication could be achieved by VATS in 91.1% of TE patients, whereas it was possible in 77.2% of nontubercular group. Need for postoperative ventilation (10% vs. 1.2%, P = 0.0011) and intensive care unit (ICU) stay (25.2% vs. 3%, P = 0.001) was significantly higher in nontubercular group. Nontubercular group was found to have significantly higher number of complications (13.4% vs. 5.4%, P = 0.02) and postoperative mortality (10% vs. 0, P = 0.001). Conclusions Higher percentage of TE cases were managed by VATS with reduced operative time, less blood loss, and lower conversions. Need for postoperative ventilation, ICU stay, and complications including mortality were more in NTE.

Abstract
Resection and anastomosis is an effective option for the management of complex tracheal stenosis, however, it's not without the complications. This study aims at evaluating various factors predicting anastomotic complications after trachea resection and anastomosis. This is a retrospective analysis of database from a dedicated thoracic surgical unit in New Delhi, India over 7 years. An analysis of demographic details, perioperative variables including complications were carried out. Analysis of various factors predicting anastomotic complications was performed. Out of 65 patients in the study, 49 (75.3%) were males and 16 (24.7%) were females. Median age of the patients was 31 years. Stenosis was cervical in 80%, cervico-thoracic in 15.4% and thoracic in 4.6% of patients. Median length of stenosis was 2.9 cm (1-4.2). 53 (81.6%) patients had some kind of preoperative intervention, where as rest 12 (18.4%) patients had no intervention at all. Out of 65 patients, 26 (40%) had crico-tracheal anastomosis while 39 (60%) had tracheo-tracheal anastomosis. Median length of resected tracheal segment was 3.3 cm (1-5). Overall complication rate (anastomotic + non-anastomotic) was 18.4% in which anastomosis related were in 4 (6.1%) patients. Resection of tracheal segment ≥ 3.5 cm, presence of diabetes mellitus and pre-operative use of corticosteroids were statistically significant factors for the onset of complications. Perioperative mortality rate was 1.5% (n = 1). Length of resection > 3.5 cm, presence of diabetes mellitus and pre-operative prolonged use of corticosteroids were significant predictors for the anastomotic complications.

Abstract
BACKGROUND Thoracoscopic bilateral dorsal sympathectomy is the standard of care for primary palmo-axillary hyperhidrosis. This study aims at studying the surgical outcomes with special emphasis on the incidence of compensatory hyperhidrosis (CH) after thoracoscopic dorsal sympathectomy. Post-procedural patient satisfaction as well as quality of life was measured and analysed. MATERIALS AND METHODS This is a retrospective analysis of sixty thoracoscopic dorsal sympathectomy surgeries in thirty patients in a tertiary level thoracic surgery centre over 2 years. Various peri-operative variables were recorded and assessed. Incidence of CH was noted and analysed in relation to patient satisfaction and record was made of quality of life at the time of discharge, at 3 months and 1-year follow-up following surgery. RESULTS We performed sixty video-assisted thoracoscopic sympathectomies in 30 patients. The mean operative time was 44.93 ± 10 min. The mean hospital stay was 1 day. There were no immediate post-procedural complications. All the patients had complete resolution of palmar and axillary hyperhidrosis. Fifty per cent of our patients (15/30) had some degree of CH after surgery. Quality-of-life measurement showed very good satisfaction by 100% at discharge, by 93.3% at 3 months and at 1 year. Those 6.66% of patients were partially satisfied/not satisfied because of the presence of moderate-to-severe CH. CONCLUSION A significant percentage of the patients with primary palmo-axillary hyperhidrosis will be very satisfied with the procedure at 1 year after surgery despite 50% of them developing CH. Detailed counselling regarding CH in the pre-operative period would minimise the dissatisfaction rate after surgery.

Abstract
Background: Delhi is one of the most polluted cities in the world with annual average ambient PM10 and PM2.5 levels exceeding the World Health Organization standards by over 15 fold. We aimed to study the prevalence of respiratory and allergic symptoms and asthma among adolescent children living in Delhi (D) and compare it with children living in lesser polluted cities of Kottayam (K) and Mysore (M) located in Southern India. Methods: 4361 boys and girls between the age group of 13–14 and 16–17 years from 12 randomly selected private schools from D, K, and M were invited to participate. Modified and expanded International Study for Asthma and Allergies in Children (ISAAC) questionnaires (Q) were filled by the students who also performed spirometry using the ultrasonic flow-sensor-based nDD Spirometer. Results: 3157 students (50.4% boys) completed the Q and performed good quality spirometry. The prevalence of asthma and airflow obstruction among children living in Delhi was 21.7% using the ISAAC Q and 29.4% on spirometry, respectively. This was accompanied by significantly higher rates of self-reported cough, shortness of breath, chest tightness, sneezing, itchy and watery eyes, itchy skin, and eczema among Delhi children (vs. K-M, all P < 0.05). Delhi children were more overweight and obese (39.8% vs. 16.4%, P < 0.0001), and this was the only risk factor that was strongly associated with asthma (odds ratio [OR]: 1.79; confidence interval: 1.49–2.14), with a more pronounced effect in Delhi children (P = 0.04). Forced expiratory volume1 and Forced vital capacity values were significantly higher in Delhi children (vs. K-M P < 0.0001). Preserved ratio impaired spirometry was more common in K-M children (P < 0.0001). Conclusion: Adolescent children living in the polluted city of Delhi had a high prevalence of asthma, respiratory symptoms, allergic rhinitis, and eczema that was strongly associated with a high body mass index (BMI). Our study suggests an association between air pollution, high BMI, and asthma/allergic diseases, which needs to be explored further.

Abstract
Introduction: Fractures around the hip in the geriatric population not only lead to functional but also psychological impairment. Psychiatric disturbances can be associated with poor participation in rehabilitation, increased risk of falling again, and higher rates of mortality. The present study was undertaken to assess the association between the psychological status and functional outcome of surgically managed elderly Indian patients who had sustained fractures around the hip. Material and Methods: The present study was a hospital based prospective, single centre study. One hundred and two geriatric patients who had sustained hip fracture and had been managed surgically, having no cognitive dysfunction, living independently, having unhindered walking capability before the fracture, were included in the study. They were called for follow-up at 3rd, 6th, and 12th month after the hip surgery. Psychological assessment was done by the Hospital Anxiety and Depression Scale (HADS) and functional outcome by using the Harris hip score (HHS). Results: Our study did not show association between psychological status and functional outcome except in one sub-group. Significant correlation was observed between the psychological status and functional outcome in most of the patients in the extra-capsular group. We have identified improvement in the depression, anxiety and functional scores during the follow-up. Conclusion: We conclude that psychiatric disturbances in a geriatric patient after undergoing a surgery for hip fracture may lead to poor recovery. We recommend that all such geriatric patients should undergo a psychological assessment and proper therapy should be instituted to achieve good functional recovery.

Abstract
OBJECTIVES The goal of this study was to compare the early and intermediate surgical outcomes, including the survival of those with and without myasthenic thymoma, following robotic thymectomy. METHODS This is a retrospective analysis of prospectively maintained data of 111 patients who underwent robotic thymectomy for thymoma over 7 years in a thoracic surgery centre in India. We performed a comparative analysis of demographics, intraoperative variables and postoperative outcomes including survival of those with and without myasthenic thymoma. RESULTS Of 111 patients, 68 patients were myasthenic and 43 were non-myasthenic. The need to resect surrounding structures and conversions was greater in the myasthenic group (P = 0.02, P = 0.04). Postoperative complications were significantly higher in the myasthenic group (P = 0.02). No differences were observed in intensive care unit stay, the need for postoperative ventilation and the hospital stay. On correlation, a higher Masaoka stage [odds ratio 1.96, 95% confidence interval (CI) 1.22-3.15] and an aggressive World Health Organization histological diagnosis (odds ratio 1.58, 95% CI 1.10-2.26) were more likely in patients with myasthenia gravis. A total of 7 deaths (6.3%) occurred during the median follow-up of 4.2 years, 5 among those with myasthenic thymoma and 2 among patients with non-myasthenic thymoma. Due to the small number of deaths, there is insufficient evidence to draw any conclusion about the effect of myasthenia gravis on survival after surgery (hazard ratio 0.51, 95% CI 0.09-2.71; P = 0.43). CONCLUSIONS The presence of myasthenia with thymoma is associated with more adjacent structure resection, higher postoperative complications and more conversions. The use of robotic surgery for thymoma resection in patients with myasthenia could not overcome the early postoperative problems related to myasthenia gravis.

Abstract
Background This meta-analysis aimed to evaluate the incidence of tumor recurrence, postoperative myasthenia gravis, postoperative complications, and overall survival after limited versus total thymectomy for Masaoka stage I and II thymoma. Methods A systematic search of the literature was conducted using the PubMed, Embase, MEDLINE, and Cochrane databases to identify relevant studies that compared limited and total thymectomy in Masaoka stage I-II patients. The quality of the included observational studies was assessed using the Newcastle-Ottawa Scale. The results of the meta- analysis were expressed as log-transformed odds ratios (log ORs), with 95% confidence intervals (CIs). Results Seven observational studies with a total of 2,310 patients were included in the meta-analysis. There was an overall non-significant difference in favor of total thymectomy in terms of tumor recurrence (pooled log OR, 0.40; 95% CI, -0.07 to 0.87; p=0.10; I2=0%) and postoperative myasthenia gravis (pooled log OR, 0.12; 95% CI, -1.08 to 1.32; p=0.85; I2=22.6%). However, an overall non-significant difference was found in favor of limited thymectomy with respect to postoperative complications (pooled log OR, -0.21; 95% CI, -1.08 to 0.66; p=0.64; I2=36.1%) and overall survival (pooled log OR, -0.01; 95% CI, -0.68 to 0.66; p=0.98; I2=47.8%). Conclusion Based on the results of this systematic review and meta-analysis, limited thymectomy as a treatment for stage I and II thymoma shows similar oncologic outcomes to total thymectomy.

Abstract
Bronchial carcinoids are slow-growing tumours of the neuroendocrine family. Most of them have a benign course with excellent outcome after complete resection. Due to their location in the primary bronchi, adequate resection with lung preservation requires considerable technical expertise. In this paper we present our surgical experience with endobronchial carcinoids and analyse the factors that predict possibility of lung preservation surgery. Retrospective analysis of a prospectively maintained database of patients operated for endobronchial carcinoids for the period March 2012 to September 2019 was carried out. Demographic factors and peri-operative variables were recorded and analysed. Factors that influence surgical outcome and possibility of lung preservation surgery were analysed. A total of 137 patients underwent surgery for resection of carcinoid tumours, out of which 100 had endobronchial carcinoids whereas 37 had peripheral carcinoids. The surgical procedure in 100 patients with endobronchial carcinoids included 14 left main bronchus sleeve resections, 13 pneumonectomies (7 right sided and 6 left sided), 10 right lower and middle bi-lobectomies, 10 lobectomies (4 left upper, 2 left lower and 4 right upper), and 53 sleeve lobectomies (18 left upper lobe sleeves, 8 left lower lobe sleeves, 20 right upper lobe sleeves, 5 right middle lobe sleeves and 2 right lower lobe sleeve lobectomies). There was no operative mortality. Median tumour size was 3.9 cm (range 5-130 mm). On univariate analysis, longer duration of symptoms was associated with poor surgical outcomes. On multivariate analysis, tumour in the main bronchus, duration of disease < 3 months (p = 0.006), left-sided disease (p = 0.03), and presence of healthy distal lung parenchyma (p < 0.001) were associated with successful lung preservation. Majority of endobronchial carcinoid tumours can be managed with lung-sparing procedures with minimal morbidity and mortality and excellent immediate and short-term outcomes. Early referral and experience of team performing these complex procedures are the key to success.

Abstract
Background: This study aims at describing the feasibility and safety of video-assisted thoracic surgery (VATS) in benign diseases such as pulmonary sequestrations (PSs) and report the surgical outcomes. Materials and Methods: This is a retrospective analysis of prospectively maintained data of 25 patients who were operated for PS over 7 years at a dedicated thoracic surgery centre in India. Pre-operative details, operative technique and details, post-operative details and complications were recorded and analysed. Results: There were 15 (60%) males and 10 (40%) females, with a median age of 22.28 years (range, 16–28 years). All patients had intra-lobar type of sequestration. The most commonly involved was left lower lobe (n = 15 patients, 60%) followed by the right lower lobe (n = 10 patients, 40%). The origin of blood supply was from the descending thoracic aorta in 18 patients (72%), the abdominal aorta in 5 (20%) and the coeliac trunk and the inferior phrenic artery in one patient (4%) each. All patients underwent complete lobar resection. One patient was converted because of dense hilar adhesion. The average duration of surgery was 179 min and the average blood loss was 204 ml. The median hospital stay and chest tube duration were 4 and 3 days, respectively. One patient was re-explored because of post-operative bleeding. Only one patient had an air leak for >7 days. The median follow-up was 42 months (range, 6–90 months) without any recurrence. Conclusions: VATS is a safe, feasible and effective option for PS at experienced centres.

Abstract
Objectives: Posttubercular tracheobronchial stenosis is a troublesome sequela of tracheobronchial tuberculosis. Surgical resection is the treatment of choice when repeated bronchoscopic dilatations fail. Herein, we aim to present our surgical experience in the management of this problem and also to evaluate factors affecting the surgical outcomes. Materials and Methods: This is a retrospective analysis of a prospectively maintained database at a dedicated thoracic surgical unit in New Delhi, India, over 8 years. An analysis of demographic characteristics, perioperative variables including complications were carried out. The occurrence of postoperative complications, and/or hospital stay of >7 days was considered as “poor” surgical outcomes. Various parameters were analyzed to assess the factors predicting surgical outcomes. Results: A total of 20 patients were surgically managed in the study period. Two patients had tracheal stenosis. The left main bronchus was involved in 16 patients. In these 16 cases, 12 cases underwent lung preserving surgery (bronchial sleeve resection and sleeve lobectomy) and rest of 4 cases required pneumonectomy. All postoperative complications occurred in 5 (25%) patients. Prolonged air leak was the most common postoperative complication. On univariate analysis, surgical outcomes were poor in patients who had longer duration of symptoms (P = 0.03) and with >2 episodes of preoperative balloon dilatations (<0.001). On multivariate analysis, “total number of dilatations <4 times,” emerged as a significant predictive factor for lung preservation surgery. Conclusions: Surgical intervention is safe, feasible, and effective in tubercular tracheobronchial stenoses which fail to respond to bronchoscopic interventions. Early referral for surgery favors lung preservation.

Abstract
INTRODUCTION Eventration of the diaphragm results in impaired respiratory mechanics, which leads to symptoms of dyspnea. Robotic diaphragmatic plication is a recently reported technique that has had good immediate outcomes. The aim of this study was to describe our transthoracic and transabdominal plication techniques and to analyze the safety, efficacy, and feasibility of robotic diaphragmatic plication in an Indian setting. METHODS This retrospective study was conducted at a large tertiary care center in a dedicated thoracic surgery unit. To measure the efficacy of plication, we administered a pulmonary function test to each patient at baseline and 6 months postoperatively and then compared the results. RESULTS Eighteen patients underwent robotic diaphragmatic plication during the study period. Of these 18 patients, 12 underwent surgery via a transabdominal approach, and 6 underwent surgery via a transthoracic approach. Surgery was completed robotically in 17 patients. The comparison of the preoperative and postoperative pulmonary function test results showed that the mean ± SD increase in forced expiratory volume in 1 second (FEV1 ) was 19.9 ± 22.0% (P = .002) and the mean increase in FEV1 /forced vital capacity was 5.7 ± 2.5 % (P = .225), indicating a significant improvement in FEV1 after surgery. CONCLUSION Robotic diaphragmatic plication can be performed transthoracically or transabdominally with good surgical outcomes. It is safe, effective, and feasible.

Abstract
Objectives: The diagnosis of traumatic transection of main bronchus is often delayed, resulting in attempts at surgical repair sometimes even months after the injury. Our aim is to analyze the factors affecting surgical outcome in patients undergoing lung preserving bronchial re-implantation for bronchial transection. Materials and Methods: This is a retrospective analysis of prospectively maintained data of 10 cases of traumatic transection of main bronchus who underwent bronchial re-implantation at a tertiary thoracic surgery center in India. Patients were divided into two groups based on their total length of hospital stay. Occurrence of postoperative complications and/or hospital stay >7 days were considered poor surgical outcomes. Results: Out of 10 patients, 6 were left main bronchus transections and 4 right main bronchus transections. The male-female ratio was 7:3. Right-sided bronchial injury and higher preoperative Injury Severity Score (ISS) were associated with poor surgical outcomes (P < 0.01). These patients also had significantly higher anastomotic complications, chest tube duration, and prolonged postoperative air leak. Age of the patient, preoperative hemoglobin or albumin levels, and time of referral did not influence the surgical outcomes. Conclusions: Poorer surgical outcomes were observed in patients who had right-sided main bronchus injury and higher ISSs. Time of referral did not influence the outcome. This study is limited by small sample size and retrospective nature. As no single center will have large numbers of this uncommon injury, multicenter pooled data are needed to re-affirm the findings of this study.

Abstract
Introduction: Mucoepidermoid carcinoma (MEC) is a primary salivary gland tumor also arising from nonsalivary gland organs of the body such as submucosal glands of tracheobronchial tree. Surgical resection with negative margins is the treatment of choice. All efforts should be made to preserve as much lung parenchyma as possible, by various bronchoplastic procedures. We present our experience with mucoepidermoid tumors and review their management options including lung preservation techniques and outcome of surgery. Materials and Methods: This is a retrospective analysis of prospectively maintained data of 14 patients who underwent surgery for MEC. Their demographic data; clinical presentation; and preoperative, intraoperative, and postoperative details were recorded. All patients underwent contrast-enhanced computed tomography of chest and bronchoscopy as part of workup for diagnosis and to assess the location, size, and extent of tumor; extraluminal component; and status of distal lung parenchyma. Results: There were eight male and six female patients. The median age at the time of surgery was 28.36 years (range 22–45 years). The procedures performed included right upper lobectomy and right pneumonectomy in one patient each, left main bronchus sleeve resection in six patients, left upper sleeve lobectomy in three patients, and carinal resection and reconstruction of neo carina in three patients. Twelve (85.7%) of our patients underwent lung-preserving surgery. The median hospital stay and chest tube removal duration was 4 and 3 days, respectively. The median tumor size was 1.91 cm (range 1–8 cm). The median follow-up was 24 months (ranging from 6 to 78 months). Conclusion: Radical surgery to achieve R “0” resection with aggressive emphasis on lung preservation is the mainstay of treatment of MEC. Greater awareness of these tumors is necessary to avoid misdiagnosis and to prevent delaying of potential complete resection of MEC.

Abstract
Objectives The standard management protocols are lacking in the management of pulmonary mucormycosis (PM). The present study aims at reporting our clinical experience and proposing an algorithm for the management of PM. Materials and Methods This is a retrospective analysis of a prospectively maintained database at a dedicated thoracic surgical unit in New Delhi, India, over 7 years. An analysis of demographic characteristics and perioperative variables including complications was carried out. Various parameters were analyzed to assess the factors affecting mortality after surgical intervention. Results Out of total 19 patients, 15 were males (78.9%) and 4 females (21.1%), with a mean age of 43.8 years (range, 19-72 years). Chronic kidney disease (status postrenal transplant on immunosuppressant therapy) was the most common predisposing factor in 11 patients (57.8%). All patients were initially started on antifungal therapy, and after 7-8 days, the response was assessed by computed tomography scan of the chest, and based on that, 15 patients (78.9%) were operated (surgical group) and the rest 4 (21.1%) were not (nonsurgical group). In the surgical group, lobectomy was required in 12 (80%) and pneumonectomy in 3 patients (20%). Postoperative complications occurred in 5 patients (33.3%). There were 3 perioperative deaths (within 90 days of surgery) (20%). Poor Eastern Cooperative Oncology Group performance status (>2) and longer duration of symptoms (>2 weeks) were independent predictors of mortality after surgery. The survivors in the surgical group are doing well. However, all four patients in the nonsurgical group died due to disease progression. Conclusion After few days of initiation of antifungal therapy, aggressive surgical resection must be performed (wherever feasible) to improve survival outcome in patients with PM.

Abstract
Background: Primary spontaneous pneumothorax (PSP) results from the rupture of small blebs or bullae in a patient without any pre-existing lung disease. Last decade witnessed a paradigm shift in the surgical management of pneumothorax from open to video-assisted thoracoscopic surgery (VATS) method. In this study, we aim to report our single center experience of surgical management of PSP along with surgical outcomes in 110 consecutive cases of PSP. Materials and Methods: This is a retrospective study of 110 operated cases of PSP over 5 years. Demography, computed tomography findings, operative technique, endoscopic classification (Vanderschueren), surgical duration, intraoperative and postoperative complications, duration of Intercostal Drain (ICD), hospital stay, and recurrence in follow-up were recorded. Results: The average age of patients was 27.59 years (range 9–68 years). The average number of episodes before the presentation was 2 (range 1–5). The average number of loss of working days because of symptoms, conservative management, or long-term intercostal drainage was 13.33 days (range 5–60 days). As per intra-operative findings, patients were categorized as per Vanderschueren's classification and managed accordingly. Conversion rate was in 1.8% (n = 2). Mean time to removal of chest tubes was 4 days (2–12 days). Mean hospital stay was 3.83 days (2–9 days). There were no postoperative deaths. The mean follow-up was 25.05 months (6–60 months). Overall complication rate was 3.6% (n = 4) and recurrence happened in 2.7% (n = 3) cases. Conclusions: VATS is an efficient and safe treatment modality for PSP with low recurrence rates and high level of patient satisfaction.

Abstract
Background: At present, there are no universally accepted protocols for the management of chylothorax. This study aims at reporting the clinical experience and presenting our institutional protocol for managing chylothorax. Materials and Methods: This is a retrospective analysis of chylothorax patients managed at a dedicated thoracic surgical unit over 8 years. A detailed analysis of demography and perioperative variables including complications was carried out. Factors influencing failure of conservative and surgical therapy were analyzed. Results: A total of 26 patients were included with a mean age of 42.4 years (range, 2–72 years). Postsurgical chylothorax was the most common variant (53.8%). Majority (46.1%) of the patients had >1000 ml/24 h intercostal tube drainage at presentation. All patients were initially subjected to conservative management, of which 11 (42.4%) patients were managed successfully with conservative therapy alone. Rest 15 (57.6%) patients required video-assisted thoracoscopic thoracic duct ligation, which was successful in 10/15 (66.7%) patients, whereas additional intervention was required in 5/15 (33.3%) patients. Drain output of >1000 ml/day was an independent predictor of failure of conservative therapy. Nontraumatic bilateral chylothorax was associated with high probability of failure of surgical therapy in the first attempt and may require additional treatment modality. Conclusions: Initial conservative management is recommended for all chylothorax patients, which is unlikely to succeed if daily drainage is >1000 ml/24 h. VATS thoracic duct ligation is recommended in such cases. Nontraumatic bilateral chylothorax has higher surgical failure rates. In such cases, additional procedures in the form of pleurodesis and/or thoracic duct embolization/disruption should be considered.

Abstract
Background Surgical treatment of empyema thoracis in patients with chronic kidney disease is challenging, and few studies in the literature have evaluated this issue. In this study, we aim to report the surgical outcomes of empyema and to analyze factors predicting perioperative mortality in patients with chronic kidney disease. Methods This retrospective study included data from 34 patients with chronic kidney disease (estimated glomerular filtration rate <60 mL/min/1.73 m2 for 3 or more months) who underwent surgery for empyema between 2012 and 2020. An analysis of demographic characteristics and perioperative variables, including complications, was carried out. Postoperative mortality was the primary outcome measure. Results Patients' age ranged from 20 to 74 years with a 29-to-5 male-female ratio. The majority (n=19, 55.9%) of patients were in end-stage renal disease (ESRD) requiring maintenance hemodialysis. The mean operative time was 304 minutes and the mean intraoperative blood loss was 562 mL. Postoperative morbidity was observed in 70.5% of patients (n=24). In the subgroup analysis, higher values for operative time, blood loss, intensive care unit stay, and complications were found in ESRD patients. The mortality rate was 38.2% (n=13). In the univariate and multivariate analyses, poor performance status (Eastern Cooperative Oncology Group >2) (p=0.03), ESRD (p=0.02), and late referral (>8 weeks) (p<0.001) significantly affected mortality. Conclusion ESRD, late referral, and poor functional status were poor prognostic factors predicting postoperative mortality. The decision of surgery should be cautiously assessed given the very high risk of perioperative morbidity and mortality in these patients.

Abstract
BACKGROUND Enhanced recovery after surgery protocols in tuberculous empyema surgery have the potential for improved outcomes, but have not been studied widely. This study aimed to analyze the outcomes after implementation of an enhanced recovery after surgery protocol in patients undergoing surgery for tubercular empyema. METHODS A retrospective analysis of patients who underwent surgery for tuberculous empyema in a dedicated thoracic surgery center from March 2012 to March 2019 was performed. The control group included patients operated on between March 2012 and March 2016. The enhanced recovery after surgery protocol was strictly introduced into our practice from April 2016. The study group included patients operated on between April 2016 and March 2019. All perioperative outcomes were measured, documented, analyzed, and compared between the two groups. There were 166 patients in the control group and 77 in the study group. RESULTS Intraoperative blood loss (p = 0.0001), prolonged air leak (p = 0.04), chest tube duration (p = 0.005), and length of stay (p = 0.003) were significantly reduced in the study group. Overall rates of postoperative complications (p = 0.04) including wound infection (p = 0.01) were also significantly lower in the study group. CONCLUSIONS Implementation of an enhanced recovery after surgery protocol in patients undergoing surgery for tuberculous empyema is feasible and effective. Application of such a protocol leads to less intraoperative blood loss, shorter hospital stay and duration of chest drainage, and fewer complications. Application of enhanced recovery after surgery protocols are strongly recommended in tubercular empyema surgery.

Abstract
Thymoma is a rare epithelial tumor of the thymus gland. Despite rarity, it is the most common tumor of the anterior mediastinum. Surgical resection in the form of extended thymectomy is the gold standard operation. Conventionally and even in the current era of significant advances in the minimally invasive surgery, open transsternal extended thymectomy is considered the gold standard, particularly for advanced-stage tumors. There is however significant evidence now available for the use of minimally invasive approaches for early-stage thymomas. This article aims to discuss the various minimally invasive approaches currently being employed for thymomas.

Abstract
This study was aimed at reporting the surgical management of superior vena cava invasion in patients with locally advanced thymoma and to evaluate surgical and survival outcomes. This is a retrospective analysis of 12 patients operated for superior vena cava resection for locally advanced thymoma over 8 years in a thoracic surgery centre in India. An analysis of peri-operative variables including complications was carried out. The influence of various predictors on survival was assessed by log-rank test. Intra-operatively, superior vena cava (SVC) alone was involved in 3 (25%) cases, SVC with BCV involvement was there in 8 cases (66.7%) and in 1 patient, the SVC involvement extended into the right atrium also. In all cases, the tumour was resected en bloc with the involved part of SVC. Repair with primary closure was sufficient in 2 cases (16.6%) in view of < 1/3rd of circumferential involvement. However, in remaining 10 cases, SVC was replaced with PTFE graft (single graft in 6 cases, Y-graft in 2 cases and twin grafts in 2 cases). No peri-operative deaths. Overall survival (OS) at 1, 3 and 5 years was 100%, 91.6% and 83.3%, respectively. Myasthenia gravis and higher Masaoka stage (IV A) of the disease were poor predictors of survival. Superior vena cava resection and reconstruction is a feasible and oncologically superior option in invasive thymoma with SVC involvement. This challenging surgical procedure should only be attempted by an experienced team of thoracic and cardiac surgeons at high-volume centre to achieve best outcomes.

Abstract
BACKGROUND Empyema thoracis is an entity seen across all age groups. This study aims at reporting a detailed microbiological profile of "pus and pleural tissue" in patients operated for empyema thoracis and also correlating it with perioperative clinical outcomes. MATERIALS AND METHODS Patients operated for empyema thoracis between 2012 and 2016 were included in the study. Patients were taken up for surgery after thorough preoperative evaluation. Perioperative outcomes were correlated with the results of microbiological analysis to evaluate their effect on clinical outcomes. RESULTS In the study, 285 patients were operated. There were 215 males (75.4%) and 70 females (24.6%). Tuberculosis (TB) was responsible for 58.2% of the cases (n = 166). Of 166, 32 patients were mycobacterial culture positive, suggesting 19.28% mycobacterial culture positivity rate. 21.8% of the total mycobacterial cultures were multidrug resistant. TB culture-positive patients had a significantly higher incidence of air leak (P = 0.03), inter-costal drain (ICD) duration (P = 0.03), and higher rates of recurrence (P = 0.03). Nontubercular empyema constituted 119 cases (41.8%). Forty-seven (39.5%) cases were culture positive. Gram-negative organisms were cultured in 30 (63.8%). Pseudomonas aeruginosa was the predominant isolate. Bacterial culture-positive patients had significantly higher conversions (P = 0.03), prolonged postoperative air leak (P = 0.04), and postoperative wound infections. CONCLUSIONS This study highlights the emergence of Gram-negative organisms in bacterial empyema and emergence of multidrug resistance in tubercular empyema. Clinical outcome correlation revealed increased complications in culture-positive cases in both tubercular and nontubercular empyemas.

Abstract
Carinal resections for trachea-bronchial neoplasms are technically challenging and have high operative morbidity and mortality. This study examines the clinical experience of carinal resections for various tracheo-bronchial tumors in a dedicated thoracic surgery center. Medical records were retrospectively reviewed from March 2012 to December 2019 to identify all patients who underwent carinal resection. An analysis of demographic characteristics, perioperative variables including complications, was carried out. Perioperative outcome was the primary outcome measure. Twenty carinal resections were performed with a median follow-up of 2.4 years (range 0.5-4.1). Procedures included 8 isolated carinal resections (40%), 6 right carinal pneumonectomy (30%), 1 left carinal pneumonectomy (5%), and 5 carinal right upper sleeve lobectomy (25%). Age of the patients range from 18 to 62 years with 9/11 male-female ratio. Mean duration from symptom onset to diagnosis was 6.1 months. All post-operative complications occurred in 7 (35%) patients. Anastomotic complications occurred in 2 (10%) patients. Out of these, 1 patient was initially managed with stent placement, ultimately requiring pneumonectomy. Post-operative events were significantly higher in group of patients who underwent carinal resection with concomitant pulmonary resection (P = 0.01). No perioperative (90-day) mortality was found. Despite advances in perioperative management, carinal resection poses challenges for both patient and surgeon. Concomitant pulmonary resection was associated with increased risk of peri-operative complications. Appropriate patient selection, meticulous surgical technique, and stringent post-operative protocols are the key for success.

Abstract
Background Minimally invasive thymectomy is fast becoming the preferred approach for myasthenia gravis and non-invasive thymoma. The most commonly employed approach for minimally invasive thymectomy is the lateral thoracic approach. Safe achievement of radical resection requires adequate visualisation of both the phrenic nerves along their entire course. In our experience, such visualisation is rather difficult with unilateral transthoracic approaches. We herein describe our technique and initial experience of 25 cases with subxiphoid robotic thymectomy (SRT) for myasthenia gravis with or without thymoma. To the best of our knowledge, this is the first such report from India. Subjects and Methods We retrospectively analysed data of patients who underwent SRT at our centre from June 2017 to September 2018. Twenty-five consecutive patients were analysed, and demographic data, total duration of the procedure, console time, blood transfusion requirement, duration of chest drainage, length of hospital stay, pain score on post-operative day (POD) 1 and day of discharge and post-operative morbidity and mortality within 90 days were recorded. Results A total of 25 patients underwent SRT. All our patients had myasthenia gravis with 4 of them having thymoma. There were 11 males and 14 females with mean age of 29.30 years (range 23-48). The mean console time was 102.85 min (range 88-120) while the mean total operative time was 199.14 (range 180-220). On first POD 1, visual analogue scale score average was 5, and at discharge, it was 2. There was no 30-day or 90-day mortality. All cases of thymoma had a complete R0 resection. Conclusion Our experience suggests that subxiphoid approach offers a good operative view of the thymus in cervical region along with easy identification of bilateral phrenic nerves. Thus, SRT can be performed safely with comparable results.

Abstract
Extragonadal germ cell tumors are most commonly encountered in the anterior mediastinum. The presence of sarcomatous malignancies in these tumors is a rare phenomenon that adversely impacts patient prognosis because of poor response to conventional cisplatin-based chemotherapy. Even more unusual is the presence of florid benign somatic proliferations that overshadow the germ cell component, often resulting in misdiagnosis and inappropriate management. Two young male patients aged 17 and 28 years respectively presented with mass in the anterior mediastinum. Histopathology of both cases revealed mixed germ cell tumor admixed with prominent vascular component. Interestingly, one case showed malignant vasoformative neoplasm (angiosarcoma) while in the other the vascular proliferation was of benign nature (venous hemangioma).

Abstract
UPAS-120, a high yielding and early maturing variety of pigeon peas released by the Department of Plant Breeding, CCS Haryana Agricultural University, Hisar contained a significant amount of phytic acid, i.e. 886 mg/100 g. When it was subjected to various domestic processing and cooking methods viz. soaking (6, 12, 18 h), dehulling, ordinary as well as pressure cooking and germination (24, 36 and 48 h), a drastic decrease in level of phytic acid with a remarkable increase in the HCl-extractability of mono, divalent, and trivalent ions, like calcium, phosphorus, and iron occurred. Germination (48 h) was found to be the best method for decreasing the phytic acid content, i.e. 35 to 39 percent less than the control and significantly (p < 0.05) increasing the non-phytate phosphorus and HCl-extractable phosphorus. Pressure cooking of soaked-dehulled pigeon pea also rendered equally good results. The calcium, phosphorus, and iron contents of pigeon pea seeds were 197.3, 473.1, and 9.91 mg/100 g, respectively; some losses varying from 3 to 9 percent were noticed when the legume was subjected to soaking, cooking, and germination but the maximum losses, i.e. 23 percent, occurred when the seeds were dehulled. However, HCl-extractability of Ca, P, and Fe improved to a significant extent when the pigeon pea seeds were soaked, soaked-dehulled, cooked and sprouted which may have been due to decrease in the phytate content followed by processing and cooking. The significant negative correlations between the phytic acid and HCl-extractability of minerals of processed pigeon pea strengthens these findings.
