Thoracic Surgeons' Perspective on the Management of Primary Spontaneous Pneumothorax

OBJECTIVE

The study aimed to determine the current practice of thoracic surgeons in the management of primary spontaneous pneumothorax in Saudi Arabia and to compare the results with the British Thoracic Society guidelines.

MATERIAL AND METHODS

This is a questionnaire-based study. The questionnaire included 41 questions and was directed to those involved in the management of primary spontaneous pneumothorax in Saudi Arabia; namely thoracic, cardiac, and general surgeons. It was distributed electronically through email. Out of 47 registered surgeons at the time of the study, 47 responses were obtained with a 100% response rate.

RESULTS

Among the participants, 39 were thoracic surgeons. It was noted that all surgeons agreed on ordering an initial chest radiograph and most would order an additional view. Also, approaches varied regarding grading systems used. While 26% of the respondents use the British Thoracic Society grading system, 16% follow the American College of Chest Physicians system, and the rest chose other parameters. The majority of surgeons would choose a chest tube of a size not greater than 28 Fr for initial placement. As for video-assisted thoracoscopic surgery, we noted that 55% of the respondents opted for 3 ports, while 36% would place 2 ports.

CONCLUSION

Primary spontaneous pneumothorax is a common condition managed by thoracic surgeons. Various guidelines were established to guide practice. Our study showed some variability in practice which could result in serious medico-legal consequences and can affect the careers of thoracic surgeons. We hope that our results will shed light upon variabilities to influence proper directed management.

Primary Pulmonary Synovial Sarcoma with Hemothorax: a Case Report

Background

Synovial sarcoma is a rare and aggressive soft tissue malignancy most commonly arises from periarticular tissue of the extremities. Although several cases in the literature have reported different origins, primary pulmonary synovial sarcoma (PPSS) is an exceedingly rare and underrecognized entity, accounting for 0.5% of all lung malignancies. Clinical presentation includes chest pain, dyspnea, cough, and hemoptysis. The finding of hemothorax is a rare presentation and was barely reported in the literature. Due to its rarity and aggressive nature, the optimal treatment is unclear, while the mainstay remains surgical resection with chemo- and/or radiation therapy.

Objective

To report a case of hemorrhagic effusion subsequently diagnosed with primary pulmonary synovial sarcoma with the main objective of enriching the literature regarding this rare malignancy.

Case report

A 52-year-old male smoker with a background of coronary artery disease, hypertension, and diabetes mellitus was referred to our hospital. The patient presented with a history of chest pain, dyspnea, and massive right-sided pleural effusion. Laboratory investigations were unremarkable except for anemia. Chest x-ray showed a complete opacity on the right lower zone with right-sided pleural effusion. Thoracentesis was done and revealed hemorrhagic exudative effusion. Computed tomography (CT) scan showed a right heterogeneous lung mass compressing the medial segment of the middle lobe. Subsequently, the patient underwent bronchoscopy, which showed compression and edema on the right middle lobe bronchus with traces of blood coming from the right lower lobe. The patient underwent a right posterolateral thoracotomy, a fungating mass eroding the medial segment of the middle lobe was resected that was diagnosed as high-grade primary pulmonary synovial sarcoma. Radiotherapy was instituted. The patient died after two years due to recurrence.

Conclusion

PPSS is an aggressive disease with poor prognostic outcomes, and Its presentation is almost similar to other lung malignancies. Meanwhile, there is no definitive management guideline, and most management depends on surgical resection if feasible with adjuvant chemo-radiation therapy.

Pneumothorax in Critically Ill COVID-19 Patients: Prevalence, Analysis of Risk Factors and Clinical Outcomes

BACKGROUND

Previous studies have been conducted to assess pneumothorax. However, few studies were done to assess pneumothorax in COVID-19 patients in the intensive care unit (ICU).

OBJECTIVE

Our aim is to describe and analyze the prevalence, clinical characteristics, risk factors, and outcomes of COVID-19 pneumothorax patients in the intensive care unit.

METHODS

We performed a retrospective review of the medical records of 418 patients, who tested positive for COVID-19 by polymerase chain reaction test and required ICU admission in King Fahad Hospital of The University from 02/01/2020 to 01/09/2021. A total number of 36 pneumothorax patients were included in the study.

RESULTS

Of 418 patients who were followed up in the intensive care unit as COVID-19 cases, 36 patients developed a pneumothorax (8.61%). The mean age of the patients was 55.6 ± 15.06 years, 23 patients were male, and 13 were female. Seventeen patients were obese, and only one patient was an active smoker. Twenty-four patients had at least one comorbidity; hypertension was the most common. Thirty-two patients were intubated, and the duration of intubation was 23.23 ±15.9 days. The time from intubation to pneumothorax development was 8.8 ± 9.3 days. Six patients were on bilevel positive airway pressure ventilation (BIPAP), 2 patients on continuous positive airway pressure ventilation (CPAP), 3 patients on High-Flow Nasal Cannula ventilation (HFNC), 9 patients on pressure-control ventilation (PC), and 16 patients on pressure regulated volume control ventilation (PRVC). Of 36 patients, 26 died, and the mortality rate was 72.2%.

CONCLUSION

Our study showed that risk factors of pneumothorax occurrence in COVID-19 critically ill patients include male patients, hypertension, diabetes mellitus, endotracheal intubation and mechanical ventilation. More efforts should be made to determine the risk factors and assess the outcomes of those patients to develop preventive measures and management guidelines.

Giant Esophageal Leiomyoma: Diagnostic and Therapeutic Challenges

BACKGROUND Leiomyoma is a rare, benign, esophageal tumor that does not often measure >10 cm. Here, we report a case of giant esophageal leiomyoma in a 24-year-old man. CASE REPORT A 24-year-old man who smoked and had primary hypertension and glucose-6-phosphate dehydrogenase deficiency presented with a history of shortness of breath and productive cough with yellowish sputum, a long history of dysphagia to solid food, and a weight loss of 7 kg over 2 months. A chest X-ray revealed a mediastinum with a width >8 cm. Computed tomography of the patient's chest revealed a multilobulated mass that originated from the upper and middle thoracic esophagus, caused severe narrowing of his esophageal lumen, and was compressing his trachea and right main bronchus. Resection of the tumor was performed and, because of the large defect after the surgery and the mucosal necrosis, the patient underwent an Ivor-Lewis esophagectomy. His postoperative course was uneventful. He had no symptoms when he was seen in the outpatient clinic for follow-up and fully recovered. CONCLUSIONS Giant esophageal leiomyoma (GEL) is a rare oncological entity that presents several diagnostic and therapeutic challenges because of the scarcity of information in the medical literature on surgical management. The descriptions of techniques for surgical resection of GEL do not include ways to effectively perform subsequent reconstruction. The aim of the present paper was to contribute to this scant information by reporting our experience with performing an Ivor-Lewis esophagectomy to manage a case of GEL.

Sternoclavicular joint osteomyelitis; delayed bone resection with muscle flap: A case report

INTRODUCTION

Sternoclavicular joint (SCJ) osteomyelitis is a very rare condition. Here, we report an uncommon case of a complicated SCJ osteomyelitis in a patient with an anterior chest wall trauma.

PRESENTATION OF CASE

A 61-year-old male a known case of dyslipidemia, hypertension (HTN), and type II diabetes mellitus (T2DM). The patient presented with pain and erythema over the right SCJ following trauma to the same location. Two weeks later, the patient presented with erythematous swelling with a sinus discharging pus, although he was discharged on oral antibiotics, analgesics, and had underwent an incisional drainage. Computerized Tomography (CT) of the chest showed fluid collection surrounding the right SCJ together with joint effusion suggestive of SCJ osteomyelitis. The patient underwent initial debridement and a definitive bone resection with pectoralis muscle flap two weeks following. Five months later, the patient was seen in the outpatient clinic, the wound was completely healed, and he has a normal function of the right arm.

DISCUSSION

The management of SCJ osteomyelitis is not well established, yet it can be approached medically, surgically, or both.

CONCLUSION

Surgical intervention is indicated in cases of SCJ osteomyelitis after the failure of antibiotic therapy trial. This is especially the case in the presence of abscess and bone destruction. SCJ debridement followed by delayed resection and pectoralis muscle flap might offer better results than merely debridement alone or with resection of the joint.

Intercostal hemangioma: Case report of a rare chest wall tumor in childhood

•

Intercostal hemangioma is an extremely rare disease, accounting for approximately 0.01% of all benign hemangiomas.

•

Hemangiomas are prone to bleed spontaneously or after minor traumatic injury.

•

Complete excision of the tumor is mandatory even after embolization to prevent recruitment of a collatera1 blood supply.

Introduction

Intercostal hemangioma is an extremely rare disease. It is difficult to distinguish intercostal hemangioma from other chest wall tumors. The difficulty in preoperative diagnosis may result in incomplete surgical resection and hence a high rate of recurrence.

Case presentation

A 14-year-old boy who presented with asymptomatic right lateral chest wall mass with no history of trauma. Different radiological modalities were employed for diagnosis including computed tomography (CT) showed a soft tissue mass 6.5 × 4 × 5.6 cm in size abutting 5th and 6th ribs. Magnetic resonance imaging (MRI) revealed iso-intense signal in T1 and hyperintense signal in T2, that is higher than that of adjacent muscles in the inferolateral right chest wall which was compatible with intercostal hemangioma. The patient underwent surgery for excision of the mass. Through right posterolateral thoracotomy, there was a well-demarcated mass abutting 5th, and 6th ribs filling the right 5th interspaces. Histopathological examination confirmed the diagnosis of intercostal hemangioma.

Discussion

Chest wall hemangiomas are uncommon and mostly arise outside the rib cage. Hemangiomas rarely occur in the intercostal space, and most of these originate from intercostal muscles (Agarwal et al., 2006). Watson and McCarthy postulated two theories for the etiology of hemangiomas. The more widely supported theory claims that hemangiomas are of congenital origin. The other theory proposes a traumatic origin of hemangiomas.

Conclusion

Complete surgical resection should not be compromised by the resultant chest wall defect to prevent recurrence.

Thoracic Complications of Bariatric Surgeries: Overlooked Entities

INTRODUCTION

Bariatric surgeries are increasingly performed to treat obesity worldwide. The currently available literature on these surgeries mainly focuses on their abdominal complications, giving less attention to their thoracic ones. Hence, the present work aimed to highlight the thoracic complications associated with bariatric surgeries.

METHODS

A retrospective descriptive study was performed and involved the review of the medical charts of 390 patients who underwent different bariatric surgeries between January 2014 and January 2017 in our hospital or who were referred to us from other centers after their specific operations. The data of patients who developed thoracic complications and who required further intervention were identified and categorized by the modality of diagnosis, outcome, duration of hospital and ICU stays, and management. Patients with a history of a preexisting pulmonary disease were excluded.

RESULTS

Twenty-six patients were observed to have thoracic complications secondary to their bariatric surgeries. Twenty-two patients (84.6%) received post-laparoscopic sleeve gastrectomy (LASG). Nine patients (34.6%) required ICU stays. Twenty patients (76.9) had incidences of pleural effusion in the postoperative period. The mean duration of hospital and ICU stays were 4.4 ± 11.67 days and 15 ± 19.36 days, respectively. Other reported thoracic complications included esophageal perforations, thoracic empyema, septic pericardial effusion, and pancreaticopleural fistula.

CONCLUSION

Bariatric surgeries are safe procedures in selected patients. There is a significant amount of literature describing abdominal, nutritional, neurological, and even ophthalmic complications after bariatric surgeries. Being that they are relatively rare, thoracic complications are underreported in the literature. The management of thoracic complications after bariatric surgery requires awareness and a high index of suspicion to prevent further morbidities and mortalities.

Influence of meteorological factors on the onset of primary spontaneous pneumothorax

Introduction Although links between meteorological conditions and primary spontaneous pneumothorax have been proposed, the reports are controversial. The aim of the study is to correlate between climatic changes and the development of this condition. Materials and methods A retrospective chart review included all patient presenting with primary spontaneous pneumothorax to King Fahd Hospital, Imam Abdulrahman Bin Faisal University, Alkhobar, Saudi Arabia, from 1 January 2005 to 31 December 2016. Meteorological data were collected from King Abdulaziz airbase station using an online source for the same time interval. The data were analysed to determine differences in weather conditions between days on which primary spontaneous pneumothorax occurred and those in which it did not. Logistic regression model was used to obtain predicted risks for the onset of primary spontaneous pneumothorax with respect to weather conditions. Result Two hundred and eighty-nine patients were found to have primary spontaneous pneumothorax in the 281 days included in the study. Among the meteorological parameters, significant differences were found in average temperature and atmospheric pressure difference between day of admission and two days before the admission, between days with primary spontaneous pneumothorax and days without. There was no significant difference in the other meteorological factors between days with primary spontaneous pneumothorax and days without. Conclusion Two hundred and eighty-nine patients were found to have primary spontaneous pneumothorax in the 281 days included in the study. Among the meteorological parameters, significant differences were found in average temperature and atmospheric pressure difference between day of admission and two days before the admission, between days with primary spontaneous pneumothorax and days without. There was no significant difference in the other meteorological factors between days with primary spontaneous pneumothorax and days without.
