Should wide chest wall resections and reconstruction intimidate thoracic surgeons?

Background: This study aimed to compare patients in whom wide chest wall resection and reconstruction or primary closure was performed. Methods: A total of 63 patients who underwent chest wall resection and reconstruction between January 2018 and December 2022 were included in the retrospective study. The patients were divided into two groups: the first group, which included 31 patients (14 males, 17 females; mean age: 44.6±16.4 years; range, 16 to 71 years) who were closed primarily, and the second group, constituting 32 patients (25 males, 7 females; mean age: 54.6±17.2 years; range, 9 to 80 years) who underwent reconstruction with plates and meshes. Results: There was no significant difference between the two groups in terms of smoking and diabetes. Primary chest wall or metastatic tumor was determined in 33 patients; benign tumor and trauma were determined in 30 patients. The difference between the two groups in mean defect diameter (p=0.009), mean number of plates used (p<0.001), and mean hospital stay (p<0.001) was statistically significant. However, there was no significant difference in terms of complications (p=0.426). Conclusion: Wide chest wall resection and reconstruction is a safe and feasible surgical procedure when compared with primary closure.

Transthoracic robotic plication for diaphragmatic elevation.

Background: This study aims to evaluate the feasibility, safety, and efficacy of transthoracic robot-assisted surgery for diaphragmatic plication and to describe our surgical approach in detail. Methods: Between January 2014 and January 2020, a total of 13 patients (11 males, 2 females; median age: 55 years; range, 24 to 70 years) who underwent diaphragmatic plication with the robotic system were retrospectively analyzed. The changes in the Medical Research Council dyspnea scale, forced expiratory volume in 1 sec, body mass index, and quality of life scale scores of the patients before the operation and at the first year of follow-up were examined. Results: Twelve of the operations were performed on the left side. The median pre- and postoperative Medical Research Council dyspnea scores were 2 (range, 1 to 4) and 1 (range, 1 to 4), respectively, indicating a statistically significant improvement (p=0.008). A significant improvement was detected in the forced expiratory volume in 1 sec of the patients in the first year after surgery (p=0.036). In terms of quality of life parameters, only, in the physical health subscale, the scores were statistically significantly different in the pre- and postoperative first-year follow-up (p=0.002). Median time to chest tube removal was 1 (range 1-5, IQR=0,5) days. Median total length of hospital stay was 2 (range 2-18, IQR=3) days. Conclusion: Owing to its technical dexterity, the robot enables the plication to be performed easily and safely. Late improvement in respiratory functions is reflected in quality of life.

Surgical Management of Multiple Hydatid Cysts in Second Trimester Pregnancy.

Although hydatid cysts are an endemic infestation, experience in surgical management of pregnant women is quite limited. This report aims to share the results and experiences gained from the management and surgery of a woman with a second trimester pregnancy who presented with asphyxia because of the rupture of a giant bilateral hydatid cyst.

A comparative study of pneumomediastinums based on clinical experience.

BACKGROUND: Pneumomediastinum (PM) is the term which defines the presence of air in the mediastinum. PM has also been described as mediastinal emphysema. PM is divided into two subgroups called as Spontaneous PM (SPM) and Secondary PM (ScPM). METHODS: A retrospective comparative study of the PM diagnosed between February 2010 and July 2018 is presented. Forty patients were compared. Clinical data on patient history, physical characteristics, symptoms, findings of examinations, length of the hospital stay, treatments, clinical time course, recurrence and complications were investigated carefully. Patients with SPM, Traumatic PM (TPM) and Iatrogenic PM (IPM) were compared. RESULTS: SPM was identified in 14 patients (35%). In ScPM group, TPM was identified in 16 patients (40%), and IPM was identified in 10 patients (25%). On the SPM group, the most frequently reported symptoms were chest pain, dyspnea, subcutaneous emphysema and cough. CT was performed to all patients to confirm the diagnosis and to assess the possible findings. All patients prescribed prophylactic antibiotics to prevent mediastinitis. CONCLUSION: The present study aimed to evaluate the clinical differences and managements of PMs in trauma and non-trauma patients. The clinical spectrum of pneumomediastinum may vary from benign mediastinal emphysema to a fatal mediastinitis due to perforation of mediastinal structures. In most series, only the SPM was evaluated in many aspects, but there are fewer studies comparing the evaluation and management of traumatic and non-traumatic PMs. The patients with TPM who have limited trauma to the thorax and who do not have mediastinal organ injury in their imaging studies can be followed up and treated like SPM patients who do not have mediastinal organ injury, and both have good clinical course.

Demographic characteristics of pectus deformities across Turkey.

BACKGROUND: This study aims to investigate the demographic characteristics and familial inheritance of pectus deformities across Turkey. METHODS: Demographic characteristics of a total of 5,098 patients (5,028 males, 70 females, mean age 23.6 years; range, 1 to 56 years) with pectus excavatum and pectus carinatum admitted to our outpatient clinic between January 1996 and December 2018 were retrospectively analyzed. The distribution of the patients across the country was made according to seven regions and 81 provinces. Familial inheritance was investigated using patients" data obtained from the clinical records and telephone calls. RESULTS: Of all patients, 3,330 (65.3%) had pectus excavatum and 1,768 (34.7%) had pectus carinatum deformity with a pectus excavatum-to-pectus carinatum ratio of 1/1.9. In the Southeast Anatolia region, the rate of pectus excavatum was lower than the overall average and higher in the Marmara region (p=0.009 and p=0.037, respectively). In the Southeast Anatolia region, the rate of pectus carinatum was higher than the general average and lower in the Marmara region (p=0.001 and p=0.003, respectively). Kastamonu, Çankiri, Karabük, and Sinop were the most common provinces for pectus deformity cases. Family history was positive in 39% of pectus excavatum and 43% of pectus carinatum patients. All regions showed a similar distribution in terms of the presence of family history. CONCLUSION: This is the first study to report the distribution of pectus deformities in Turkey and the high frequency of pectus deformities in certain regions and provinces of Turkey indicates familial inheritance.

A rare cause of pneumomediastinum and subcutaneous emphysema: Tooth extraction.

Pneumomediastinum is defined as the presence of free air between mediastinal structures. Although most of the cases occur spontaneously or due to traumatic reasons, they may rarely be observed after dental procedures. It is considered that the use of high speed air turbin drill during dental procedures might cause mediastinal emphysema. High-pressured air dissects the soft tissues starting from the impaired dento-alveolar membrane and reaches the mediastinum. Contaminated fluid and air can reach the mediastinum after the deterioration of the intraoral barrier and may result in highly mortal descending mediastinitis. In this article, we present a 53-year-old female patient of pneumomediastinum developing after tooth extraction using high-speed air turbine.

Investigation of the preventive effect of proanthocyanidin in ischemia-reperfusion injury in lung transplantation: An experimental study.

BACKGROUND: This study aims to investigate the preventive effect of proanthocyanidin against ischemia-reperfusion injury after lung transplantation. METHODS: The study included 12 swines (weighing 35±5 kg) and separated into four groups. Groups 1 and 3 were identified as control groups and left upper lobectomy was performed. Groups 2 and 4 were identified as transplantation groups and left lower lobectomy and heterotransplantation were performed. Proanthocyanidin was only given to groups 3 and 4. Tissue samples were analyzed under light microscope and histopathological findings were recorded. RESULTS: There was no statistically significant difference between control groups in terms of the numerical values of histopathological findings that include congestion (p=0.565), alveolar edema (p=0.197) and peribronchial inflammation (p=0.444). However, numerical values of acute cellular rejection were statistically significantly different between transplantation groups (p=0.048). Mean oxidative stress enzyme levels were higher in group 2 compared to group 4; however, the difference was not statistically significant (p>0.05). CONCLUSION: According to the findings of our experimental study, proanthocyanidin can be safely used in lung transplantation based on its preventive effect in ischemia-reperfusion injury that may lead to morbidity and mortality.

Treatment of compensatory hyperhidrosis of the trunk with radiofrequency ablation.

OBJECTIVES: Although Endoscopic Thoracic Sympathectomy is a widely accepted treatment method for patients with palmar hyperhidrosis, compensatory hyperhidrosis of the trunk remains a challenging side effect of the procedure. No satisfactory treatment options for this side effect were available until now. In this study, we aimed to define a new procedure for the treatment of compensatory hyperhidrosis of the trunk. METHODS: A total of 10 patients admitted our institution for the treatment of compensatory hyperhidrosis of the trunk were enrolled in the study between November 2010 and January 2012 in a prospective manner. Sympathetic blockage was achieved via radiofrequency thermo-ablation technique. The results of treatment were evaluated via telephone calls. RESULTS: Ten patients (2 females, 8 males) underwent radiofrequency thermo-ablation of T6 sympathetic ganglion for compensatory hyperhidrosis of the trunk. The mean age was 29.2 years and the median duration of symptom was 10.5 months. The median follow-up period was 14 months. Six of ten patients (60%) were treated successfully. There was no procedure related complication. CONCLUSION: The radiofrequency treatment for patients with compensatory hyperhidrosis of the trunk is an alternative option with promising results.

Reconstruction with a patient-specific titanium implant after a wide anterior chest wall resection.

The reconstruction of full-thickness chest wall defects is a challenging problem for thoracic surgeons, particularly after a wide resection of the chest wall that includes the sternum. The location and the size of the defect play a major role when selecting the method of reconstruction, while acceptable cosmetic and functional results remain the primary goal. Improvements in preoperative imaging techniques and reconstruction materials have an important role when planning and performing a wide chest wall resection with a low morbidity rate. In this report, we describe the reconstruction of a wide anterior chest wall defect with a patient-specific custom-made titanium implant. An infected mammary tumour recurrence in a 62-year old female, located at the anterior chest wall including the sternum, was resected, followed by a large custom-made titanium implant. Latissimus dorsi flap and split-thickness graft were also used for covering the implant successfully. A titanium custom-made chest wall implant could be a viable alternative for patients who had large chest wall tumours.

[Traumatic pulmonary pseudocyst: two case reports]. / Travmatik pulmoner psödokist: Iki olgu sunumu.

Traumatic pulmonary pseudocysts (TPPs) are rare sequelae of blunt chest trauma. Young adults and adolescents are predominantly affected. In this study, two cases of TPPs in young patients are presented. Chest radiographs are usually insufficient for the diagnosis, and the imaging modality of choice is computed tomography (CT). TPPs are self-limiting, benign lesions that usually require no specific therapy. Surgical treatment is indicated in rare instances and only when complications occur.

Comparison of side effects of oxytetracycline and talc pleurodesis: an experimental study.

BACKGROUND: Chemical pleurodesis is widely recommended in the treatment of refractory pleural effusion or pulmonary air leak of different etiologies. Although several agents have been used, many questions have remained unanswered about their toxicity. Talc is the most commonly used agent for the treatment, with rare, serious complications reported. Oxytetracycline pleurodesis in clinical practice has been described in a few studies, but literature reveals no experimental studies using this agent. We performed a prospective, randomized, observer-blinded, controlled study to evaluate the changes in lung histology and systemic response to pleurodesis with oxytetracycline and talc in acute and subacute phases in a rat model. METHODS: Forty-two male albino Wistar rats were divided into three groups and 3 subgroups with 7 animals in each. Group 1 was given oxytetracycline, 35 mg/kg; Group 2 was given talc slurry, 60 mg/kg in 0.5 mL saline solution, and Group 3 was given only 0.5 mL saline intrapleurally. In subgroups "a" the nimls were sacrificed at the postoperative 72nd hour and, in subgroups "b", on the postoperative day 7. The surfaces were graded by microscopic examination. RESULTS: Oxytetracycline produced alveolar collapse, hemorrhage, edema, inflammation at the postoperative 72nd hour and hemorrhage on the postoperative day 7, while talc produced significant edema, inflammation, proliferation, fibrosis at the postoperative 72nd hour and hemorrhage, edema, inflammation, proliferation, and fibrosis on the postoperative day 7 (p < 0.0042). Talc produced significant edema compared to oxytetracycline on the postoperative day 7. On contralateral side, oxytetracycline and talc produced significant hemorrhage on the postoperative day 7 (p < 0.0042). CONCLUSIONS: Both agents were shown to produce pulmonary lesions. In acute phase, the pulmonary side effects of oxytetracycline were more pronounced, whereas the side effects of talc were prolonged to subacute phase. We propose that the occasional side effects in humans may be related to these changes as were observed in our rat model, and like talc, oxytetracycline must be used cautiously in patients with limited respiratory function.

Surgical management of chest wall tuberculosis.

OBJECTIVE: Tuberculosis remains one of the most fatal diseases in the world. Extrapulmonary tuberculosis increases in parallel fashion with the rise of incidence of pulmonary tuberculosis. Tuberculosis of the chest wall is rare. METHODS: Our study retrospectively evaluated 10 patients with tuberculosis of the chest wall who were treated with surgery in addition to antituberculous chemotherapy in the last 8 years. Seven of the lesions were located on the anterior chest wall, and three of the lesions were on the lateral chest wall. RESULTS: Surgical therapy consisted of evacuation of the cold abscess material from the cavities and wide débridement of the soft tissue planes in all patients. Partial rib resections were performed in six patients owing to costal or chondral involvement. CONCLUSIONS: Chest wall tuberculosis must be considered in the differential diagnosis of chest wall lesions, especially in endemic areas.

Repair of pectus deformities: experience and outcome in 317 cases.

BACKGROUND: The most common congenital chest wall deformities are pectus excavatum and pectus carinatum. Various techniques have been described for correction of pectus deformities. We describe our experience with surgical repair of pectus deformity (PD) in adults, including our new technique, which uses a resorbable plaque for fixation of the sternum. METHODS: We reviewed the records of 317 patients who underwent surgical correction of PD between October 1997 and December 2005. RESULTS: All of the patients were male and the median age was 21.3 years (range, 16-32 years). Of 317 patients, the type of deformity was a pectus excavatum in 230 patients and a pectus carinatum in 87 of the patients. Four different operative techniques were used. There were no intraoperative deaths or major perioperative morbidity. The complications rate was 17%. Overall mean hospital stay was 14.25 days. In 208 patients who underwent a mid-term outpatient follow up (mean, 8 months), there was no recurrence. Patient satisfaction was excellent in 234 patients, good in 79 patients and fair in 4 patients. CONCLUSION: The majority of patients with pectus deformity had been operated on during childhood; therefore there is limited published information about the correction of pectus excavatum and pectus carinatum deformities in adults. The most important point in pectus correction is to achieve proper and long-term stability of the sternum following osteotomy. Various techniques can be used for this purpose.

Pulmonary sequestration and surgical treatment.

Pulmonary sequestration is nonfunctioning, abnormal pulmonary tissue existing inside or outside the visceral pleura. It is not connected to the tracheobronchial tree. In this study, the results of 8 patients, who were diagnosed with pulmonary sequestration and treated during hospitalization in Gülhane Military Medical Academy between 1996 and 2003, were reported. Sex, age, symptoms, diagnostic approach, operative findings, procedures and postoperative outcomes were reviewed. No postoperative complications were seen. In the long-term follow-up all patients were seen to be asymptomatic. We believe surgical resection is mandatory in order to avoid infection and destruction of the normal pulmonary parenchyma even in asymptomatic cases. Furthermore, when infection occurs, major resection such as lobectomy may be necessary rather than segmentectomy or wedge resection, which involves removal of minimal pulmonary parenchyma.

Surgical management of bronchiectasis: analysis and short-term results in 238 patients.

OBJECTIVE: Bronchiectasis is defined permanent dilatations of bronchi with destruction of the bronchial wall. It is still a major cause of morbidity and mortality in developing countries. The aim of this retrospective study is to present our surgical experiences, the early and long-term results of 238 patients with bronchiectasis during a 10-year period. METHODS: We reviewed the medical records of 238 patients who underwent surgical resection for bronchiectasis between January 1992 and December 2001, at Gülhane Military Medical Academy (GMMA) Thoracic Surgery Department. Variables of age, sex, symptoms, etiology, and type of operation, mortality, morbidity and the result of surgical therapy were analyzed. RESULTS: There were 205 (86.13%) male and 33 (13.87%) female patients with an average age of 23.7 and a range of 15-48 years. The presenting symptoms were productive cough in 133 (55.88%), fetid sputum in 116 (48.73%), recurrent infections in 84 (35.29%), and hemoptysis in 39 (12.18%) patients. The disease was bilateral in 31 patients (13.02%) and mainly confined to the lower lobes in 162 (68.06%). The surgical treatment was as follows: pneumonectomy in 13 patients (5.46%), lobectomy in 189 (79.40%), lobectomy+segmentectomy in 31 (13.02%), and wedge resection or segmentectomy in five (2.1%). Staged bilateral thoracotomy was used in 14 patients. There was no operative mortality. Complications occurred in 21 patients and the morbidity rate was 8.82%. Complete resection was achieved in 154 (64.7%) patients. Follow-up data were obtained for 229 (96.21%) of the patients. Nine patients were lost to follow-up. The mean follow-up of these patients was 9 months (range, 3 months to 4 years). The symptoms disappeared in 189 patients (79.41%) and 29 patients (12.18%) had improved, whereas 11 patients (4.62%) had no improvement. Significantly better results were obtained in patients who had undergone a complete resection. CONCLUSIONS: Surgical resection for bronchiectasis can be performed with acceptable morbidity and mortality at any age. The involved bronchiectatic sites should be resected completely for the optimum control of symptoms.
