An impressive case of isolated thoracic impalement.

Case: A 61-year-old male construction worker was admitted to our Emergency Department due to being impaled in the chest after fall onto the long pole of his cement mixer. He was promptly scanned through the CT then transferred to theatre where unique technique for intubation was utilised prior to performing a Video Assisted Thoracoscopic Surgery exploration and extraction of the foreign object. Discussion: Impalement injuries are classified into Types I or II depending on the direction of movement of the human body in relation to the foreign object. There currently is no consensus on the best management of chest wall injuries involving impalements. Our case utilised Video Assisted Thoracoscopic Surgery as the dominant method of intervention together with highly skilled anaesthetic preparation. Conclusion: The combined expert anaesthetic and surgical approach utilised collectively had a role in ensuring the best possible outcome for the patient.

Ambulatory chest drainage with advanced nurse practitioner-led follow-up facilitates early discharge after thoracic surgery.

OBJECTIVES: To demonstrate the safety and feasibility of advanced nurse practitioner-led (ANP-led) outpatient follow-up after discharge with ambulatory chest drains for prolonged air leak and excessive fluid drainage. METHODS: Patients discharged with ambulatory chest drains between January 2017 and December 2019 were retrospectively reviewed. Discharge criteria included air leak < 200 ml/min or fluid drainage > 100 ml/24 h on a digital drain. Patients were reviewed weekly in the clinic by ANPs, a highly skilled cohort of nurses with physician support available. Outcomes included length of stay, duration of air or fluid leak and complications. RESULTS: Two-hundred patients were included, amounting to 368 clinic episodes. The median age was 68 ± 13 years and 119 (60%) were male. 112 (56%) patients underwent anatomical lung resection (total anatomical lung resections during the study period = 917) equating to a discharge with ambulatory chest drain rate of 12.2% in this group. The median length of stay was 6 ± 3 days and 176 (88%) patients were discharged with air leak versus 24 (12%) with excessive fluid drainage. The median time to drain removal was 12 ± 11 days. Complications occurred in 16 patients (8%) and 12 (6%) required readmission. An estimated 2075 inpatient days were saved over the study period equating to an annual cost saving of £123,167 (US$149,032) per annum. CONCLUSIONS: Patients with air leak or excessive fluid drainage can safely be discharged with ambulatory chest drains, allowing them to return to their familiar home environment safely and quickly. ANP-led clinics are a robust and cost-effective follow-up strategy and are associated with a low complication rate.

Endobronchial Valves in the Management of Persistent Air Leak in Coronavirus Disease 2019.

Pneumothorax and persistent air leak are documented complications of severe acute respiratory syndrome coronavirus 2 infection. Patients who fall into this category are often poor candidates for invasive thoracic surgical intervention. Endobronchial valves offer an effective and less invasive treatment option and can successfully treat persistent air leak and support the weaning of patients with severe acute respiratory syndrome coronavirus 2 pneumonia off ventilation.

Preoperative Physical Activity Predicts Surgical Outcomes Following Lung Cancer Resection.

OBJECTIVES: To assess whether preoperative levels of physical activity predict the incidence of post-operative complications following anatomical lung resection. METHODS: Levels of physical activity (daily steps) were measured for 15 consecutive days using pedometers in 90 consecutive patients (prior to admission). Outcomes measured were cardiac and respiratory complications, length of stay, and 30-day re-admission rate. RESULTS: A total of 78 patients' datasets were analysed (12 patients were excluded due to non-compliance). Based on steps performed they were divided into quartiles; 1 (low physical activity) to 4 (high physical activity). There were no significant differences in age, smoking history, COPD, BMI, percentage predicted FEV1 and KCO and cardiovascular risk factors between the groups. There were significantly fewer total complications in quartiles 3 and 4 (high physical activity) compared to quartiles 1 and 2 (low physical activity) (8 vs 22; P = .01). There was a trend (P > .05) towards shorter hospital length of stay in quartiles 3 and 4 (median values of 4 and 5 days, respectively) compared to quartiles 1 and 2 (6 days for both groups). CONCLUSIONS: Preoperative physical activity can help to predict postoperative outcome and can be used to stratify risk of postoperative complications and to monitor impact of preoperative interventions, ultimately improving short term outcomes.

New N1/N2 classification and lobe specific lymphatic drainage: Impact on survival in patients with non-small cell lung cancer treated with surgery.

OBJECTIVE: to validate the proposed N descriptor revision on a large cohort of patients and assess the impact of tumour location on the distribution pattern of lymph node metastases for patients with NSCLC. METHODS: This is a retrospective review of a consecutive series of patients who had anatomical lung resections. Systematic lymph node dissection was done for all patients. RESULTS: Between January 2009 and December 2019 2566 patients had surgical resection for NSCLC. 448 patients (17.5%) had histologically confirmed lymph node metastases: 257 (57.4 %) had pN1 and 191 pN2. Median age of the study population was 69.1 years. Overall survival (OS) for study population was 37.3 months with 5-year survival rate of 35.7 %. The survival analysis of the N subgroups showed the pN2 patients had a median OS of 27.9 months vs. 41.7 months for pN1 patients (p = 0.013). Analysis as per the new proposal of the N subgroups N1a vs N1b vs N2a1 vs N2a2 vs N2b showed that median survival OS was 41.7 vs. 39.2 mo vs. 33.3 mo vs. 28.9 mo vs. 24.6 mo (p = 0.099). There was statistically significant difference in survival between N2 patients with skip metastasis and N2 patients without skip metastases: OS 32.2 (95 % CI: 16.8-47.6) months vs. 24.2 months (p = 0.024). On multivariate analysis only pathological N (p = 0.011) and the new proposed N classification (p = 0.006) were independent prognostic factors for survival. CONCLUSIONS: N1 and N2 disease are heterogeneous groups and require further stratification. The number of N2 lymph node stations involved and the presence or not of N1 disease translated to significant differences in survival and therefore have to be included in N staging.

Retrospective Observational Study into the Early Causes of Death Following Surgery for NSCLC.

INTRODUCTION: Respiratory failure has historically been the major cause of mortality after elective lung resections. With improved intubation using fiber-optic scopes, better preoperative respiratory risk assessment, more advanced anesthetic single lung ventilation, and minimally invasive surgical technique, this may have changed. Our objective was to assess the main causes of mortality over the past 10 years in patients undergoing elective lung surgery in a major UK center. MATERIALS AND METHODS: A retrospective unit data search was made for all deaths during the 10-year period between January 2007 and December 2016 inclusive. All inpatient deaths within 30 days of an elective anatomical lung resection for lung malignancies were included. RESULTS: Three-thousand three-hundred sixteen lung resections for malignancy were performed in the 10-year period. There were 44 (1.3%) deaths during this period, 27 (61.4%) after open lobectomies, 8 (18.2%) after video-assisted thoracoscopic surgery lobectomies, 5 (11.4%) after sleeve lobectomies, and 4 (9%) after pneumonectomies. Causes of death included 24 (54.5%) respiratory failure, 10 (22.7%) ischemic bowel, 4 (9%) coronary events, 2 (4.5%) strokes, 2 (4.5%) on table hemorrhage, 1 (2.3%) massive pulmonary embolus, and 1 (2.3%) postoperative hemorrhage. CONCLUSION: Although respiratory failure is still a major cause of mortality in the postoperative patient, bowel ischemia has been found to be the second greatest cause of death. This study highlights the need to identify those at risk of this fatal complication during preoperative assessment and their postoperative management.

Prognostic factors including lymphovascular invasion on survival for resected non-small cell lung cancer.

OBJECTIVES: The aim of this study was to report on the influence of tumor lymphovascular invasion on overall survival and in patients with resected non-small cell lung cancer and identify prognostic factors for survival. METHODS: This is a retrospective observational study of a consecutive series of patients who had surgical resection of non-small cell lung cancer in a single institution. The study covers a 3-year period. Overall survival was estimated by Kaplan-Meier method and multivariate Cox regression analysis was used to evaluate the relationship of lymphovascular invasion and other clinicopathologic variables. A multivariate regression was used to assess the relationship between tumor lymphovascular invasion and other clinical and pathologic characteristics. RESULTS: A total of 524 patients were identified and included in the study. Two hundred twenty-five patients (43%) had tumors with lymphovascular invasion. Patients with tumor lymphovascular invasion had a lower overall survival (P < .0001). Tumor lymphovascular invasion was independently associated with visceral pleural involvement (P < .0001). In a multivariable model, lymphovascular invasion (hazard ratio [HR], 2.58; 95% confidence interval [CI], 1.63-4.09; P < .0001), parietal pleural invasion (HR, 45.4; 95% CI, 2.08-990; P = .015), advanced age (HR, 1.028; 95% CI, 1.009-1.048; P = .004), and N2 lymph node involvement (HR, 1.837; 95% CI, 1.257-2.690; P = .002) were independent prognostic factors for lower overall survival. CONCLUSIONS: Lymphovascular invasion is associated with a worse overall survival in patients with resected non-small cell lung cancer regardless of tumor stage. Parietal pleural involvement, N2 nodal disease, and advanced age independently predict poor overall survival.

The Requirement of Sutures to Close Intercostal Drains Site Wounds in Thoracic Surgery.

BACKGROUND: Chest drains are used routinely in thoracic surgery. Often a pursestring or mattress suture is used to facilitate closure of the defect on removal of the drain. This stitch can cause an unsightly scar, increase drain removal pain, and necessitate that the patient attend a community health care center to have this removed. The objective of this study was to assess whether this stitch is necessary in modern thoracic surgical practice. METHODS: Data from a single surgeon's practice were collected over an 18-month period. During this time, all patients who underwent both emergency and elective thoracic surgery who had at least one postoperative chest drain of 28F or above inserted were included in the study. The surgeon did not routinely use a suture to close the drain site. RESULTS: In all, 312 patients underwent thoracic surgery during the 18-month period. Each patient had a range of 1 to 3 drains inserted of a size between 28F and 32F. No patients had drain sutures for closure of the drain site. Four patients had pneumothoraces after drain removal requiring further chest drain insertion. Five patients had superficial drain site infections. A single patient had to have a suture inserted at a local hospital owing to leakage from the drain site. CONCLUSIONS: The use of pursestring sutures in thoracic surgery is an outdated practice that causes not only unsightly scars but is also associated with increased pain. Furthermore, these unnecessary pursestring sutures place a burden on the patient and health care system to have them removed.

Does the addition of postoperative radiotherapy to adjuvant chemotherapy offer any benefit in patients with non-small cell lung cancer and mediastinal lymphadenopathy?

A best evidence topic in thoracic surgery was written according to a structured protocol. The question addressed was whether the addition of postoperative radiotherapy (PORT) to adjuvant chemotherapy offers any benefit in patients undergoing curative resection for non-small cell lung cancer found to harbour mediastinal lymphadenopathy. A total of 77 papers were identified using the reported search, of which 11 represented the best evidence to answer the clinical question. Only studies reporting on survival data of patients receiving adjuvant chemotherapy with and without PORT were included in this analysis. The authors, date, journal, country, study type, population, outcomes and key results are tabulated. Six studies reported a statistically significant positive impact of PORT on long-term or disease-free survival (DFS) (P = 0.048-0.0001). Five more studies found no difference in terms of survival between patients receiving and not receiving PORT. Among the 11 studies, only two were randomized controlled, with one of them reporting improved disease-free (P = 0.041) but not overall survival (P = 0.073), while the other finding no difference in survival. Furthermore, three more studies reported on DFS and/or locoregional recurrence of the disease. One of these studies reported a significantly improved DFS among patients receiving PORT (P = 0.003), while two of them reported a reduced rate of locoregional recurrence in this group (P = 0.032-0.009). Many studies report a positive effect of PORT when combined in parallel or sequentially with adjuvant chemotherapy in terms of long-term, disease free survival or locoregional control of the disease in patients who have undergone surgical resection of NSCLC and are found to harbour N2 disease. However, these reports are counterbalanced by an almost equal number of studies which show no difference between PORT and no PORT. Only one study reported significantly increased radiation related adverse effects in patients undergoing chemotherapy and PORT.

New-onset atrial fibrillation after anatomic lung resection: predictive factors, treatment and follow-up in a UK thoracic centre.

Objectives: Postoperative atrial fibrillation (POAF) increases morbidity, hospital stay and healthcare expenditure. This study aims to determine the perioperative factors correlating with POAF as well as to evaluate both treatment strategies and AF persistence beyond discharge. Methods: The records of all patients undergoing anatomical lung resection over a 1-year period were retrospectively reviewed. Patients with a history of arrhythmia were excluded. POAF was defined by clinical diagnosis and electrocardiography. Pre- and postoperative demographic and clinical data were collected, and uni- and multivariable regression were performed to determine the factors associated with POAF. Results: POAF occurred in 11.4% (43/377) of patients with a mean of 3.55 days postoperatively and significantly increased hospital stay (6.78 ± 4.42 vs 10.8 ± 5.8 days (P = 0.0014)). No correlation was found with gender, hypertension, ischaemic heart disease, beta-blocker use, alcohol consumption or thyroid dysfunction. However, older age (P = 0.001) and postoperative infection (P < 0.0001; χ2 = 26.03) were found to be significant uni- and multivariable predictors of POAF. Open surgery rather than video assisted thoracoscopic surgery (VATS) (open 26/189 (13.8%); VATS 17/188 (9.0%); P = 0.150) demonstrated a tendency towards increased postoperative AF; however, this was not statistically significant. Four (9.3%) patients remained in AF on discharge, and three required long-term anticoagulation. Three (7%) patients were found to have ongoing AF at 1-month follow-up. Conclusions: Increasing age and postoperative infection are most strongly associated with POAF. Adoption of enhanced recovery protocols, along with more rigorous monitoring and early treatment of postoperative infection may help reduce POAF and its associated morbidity. Rhythm assessment is crucial to identify persistent AF after discharge, and clinicians should be vigilant for recurrence of AF at follow-up.

Does the sequence of pulmonary vasculature ligation have any oncological impact during an anatomical lung resection for non-small-cell lung cancer?

A best evidence topic in thoracic surgery was written according to a structured protocol. The question addressed was 'in patients with primary lung carcinoma, does the sequence of pulmonary vasculature ligation during anatomical lung resection influence the oncological outcomes?' A total of 48 papers were found using the reported search, of which 7 represented the best evidence to answer the question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. Among six prospective studies included, five of them randomized patients to either pulmonary vein or artery occlusion first during anatomical lung resection, while one study was retrospective. Two reports did not find any difference between pulmonary vein and artery occlusion first during long-term follow-up in terms of either disease recurrence (51 vs 53%, P = 0.7), or 5-year overall survival (54 vs 50%, P = 0.82). One report did not find any difference with regard to circulating tumour cells either after thoracotomy (5.0 vs 3.9, P = 0.4), or after the completion of lobectomy (38.0 vs 70.0, P = 0.23). One report found a higher expression of CD44v6 (P = 0.008) and CK19 (P = 0.05) in patients undergoing pulmonary arterial occlusion first. One report found that pulmonary vein occlusion before that of the pulmonary arterial branches has a favourable outcome on circulating carcino-embryonic antigen (CEA) mRNA in the peripheral blood, while another one did not find a significant difference in circulating levels of CEA mRNA (P = 0.075) and CK19 mRNA (P = 0.086) with either method. Another study reported no correlation between circulating pin1 mRNA levels in peripheral blood after the completion of the resection and the sequence of ligation of pulmonary vessels (9.95 ± 0.91 vs 14.71 ± 1.64, P > 0.05). Based on the two studies assessing the long-term outcome of patients with primary lung cancer undergoing anatomical curative resection, the sequence of ligation of pulmonary vessels does not seem to influence the oncological outcomes or survival. However, the other studies focusing on the influence of these techniques on circulating tumour cells or their molecular products report conflicting results the clinical consequences of which cannot be predicted.

Does the extent of resection affect survival in patients with synchronous multiple primary lung cancers undergoing curative surgery?

A best evidence topic was written according to a structured protocol. The question addressed was whether the extent of pulmonary resection affects survival in patients with synchronous multiple primary lung cancers undergoing curative surgery. A total of 724 papers were identified using the reported searches, of which 14 represented the best evidence to answer the clinical question. The authors, date, journal, country, study type, population, outcomes and key results are tabulated. All studies were retrospective. Eight of 14 studies found no difference in terms of median, overall or progression-free survival when a sublobar resection in the form of a wedge resection or segmentectomy was performed for at least one of the synchronous lesions. Two studies demonstrated a negative impact on survival when lobectomy or bilobectomy was not performed for each lesion. Five papers reviewed the role of pneumonectomy in this category of patients and four of them demonstrated that such an extended resection has a significantly negative impact on survival, while, in one study, although pneumonectomy when compared with sublobar resections and photodynamic therapy had decreased long-term survival, this difference did not reach statistical significance. The use of lung-sparing resections (wedge resection or segmentectomy) of at least one lesion (if technically feasible) is advised for patients with synchronous multiple primary lung cancers. Most studies do not demonstrate any differences in immediate or long-term survival with two anatomical resections. Embarking for anatomical lung resections in the form of lobectomies should be done only in those cases where there are no concerns about postoperative pulmonary reserve. The performance of a pneumonectomy should be avoided, especially for bilateral synchronous lesions, unless it is absolutely necessary.

[The treatment of spontaneous pneumothorax--focusing on the use of videothoracoscopy]. / A spontán pneumothorax kezelése különös tekintettel a videothoracoscopiára.

AIMS: Videothoracoscopy plays a leading role in the management of spontaneous pneumothorax. This study evaluates various treatment strategies based on early results. PATIENTS AND METHODS: In a five-year period 243 (184 male, 59 female, mean age: 37.1 years) patients were treated with spontaneous pneumothorax in 302 cases. In case of partial ptx observation was used in 24 (8%) and aspiration in 6 (2%) patients. Chest drain was inserted in 241 (67.6%) cases. Indications for surgery were recurrence of disease, previous contralateral pneumothorax and failure of drainage. Videothoracoscopy was indicated in 71 (23.5%), Jakoscopy in 5 (1.7%), thoracotomy in 13 (4.3%) cases. The operation was completed with partial pleurectomy in 25, talcum or mechanical pleurodesis in 32 and 3 cases, respectively. RESULTS: Conservative treatment was successful in 24 (80%) of the 30 conservatively treated cases, while chest drainage succeeded in 204 (84.7%) of the 241 cases. Conversion was needed in 8 (11.3%) cases of the 71 VATS. The remaining 63 patients recovered. Thoracotomy and Jakoscopy were successful in all cases. The postoperative complication rate was 6.3% after VATS, and 7.7% after thoracotomy. Reoperation was performed because bleeding in one case after VATS and thoracotomy. In one case empyema, and in another patient pneumonia developed after VATS. Postoperative bleeding occurred in one case after thoracotomy. The mean hospitalization was 8.5 days after drainage, 9.1 days after VATS and 11.3 days after thoracotomy. The postoperative mortality rate was 1.3% (4 patients). CONCLUSIONS: In case of spontaneous pneumothorax the first choice of therapy is chest tube drainage. VATS is indicated in case of recurrence, failure of drainage and previous contralateral pneumothorax.

[A complicated case of spontaneous oesophageal rupture managed by transgastric drainage]. / Spontán nyelocsoruptura komplikált esetének megoldása transgastricus drainage-zsal.

Spontaneous rupture of the oesophagus is an extremely serious condition with high morbidity and mortality. Primary surgical repair may be followed by numerous complications. A 29-year-old man had undergone primary surgical repair due to spontaneous rupture of the lower third of the oesophagus. After the operation he developed suture insufficiency, which could not have been stented, and transgastric drainage was performed therefore. After a slow healing of the fistula, we could avoid another operation and his oesophagus was preserved. Fortunately, a stricture did not develop either. Transgastric drainage of the oesophagus could be a good therapeutic choice in selective and complicated cases.

[Intrathoracic migration of Kirschner wires]. / Kirschner-drótok intrathoracalis vándorlása.

Orthopedic surgeons apply metallic pins to stabilize the clavicule and humerus on a daily basis. Migration of these pins into the thoracic cavity is rare. We present the case of an elderly female patient, whose right humeroscapular joint was fixed with Kirschner wires due to recurrent luxation. Six weeks later, a follow-up X-ray revealed that the pins have migrated into the right thoracic cavity, confirmed by a CT chest. Videothoracoscopic removal of the metallic pins was not possible because of dense adhesions. Right anterolateral thoracotomy was carried out, and after pneumolysis one pin was taken out from the 2nd lung segment. The other one, which was running along the cupola and entering the spinal cord, was also removed. There was no postoperative surgical complication. The authors review the literature of this rare complication and point out that pins migrating into the thoracic cavity should be removed to avoid life threatening complications.

[Abdominal hernia repair with No-React treated bovine pericardial patch]. / Hasfali sérv mutéte No-React eljárással készült borjúpericardium-folt beültetésével.

UNLABELLED: In the last decades surgical treatment of abdominal wall hernias has extensively developed. Tension free reconstruction is essential to the successful operation, which can be achieved in many cases only with the use of hernia patch or mesh. Synthetic materials gained widespread use for this purpose, which markedly reduced recurrence rate; but they can cause infections and other serious complications. Various different types of meshes have been developed during the last years, but none of them meets entirely the requirements. The authors repaired epigastric hernias with intraperitoneal implantation of specially treated bovine pericardial patch in two patients to prevent infection. Both patients recovered without postoperative complications. Follow-up examination 7 and 15 months after the operation did not reveal recurrence or any other complications. The authors describe the applied surgical technique, the advantageous properties of the bovine patch and review the literature. CONCLUSION: According to the early experiences of the authors as well as to data of the literature, the Shelhigh No-React bovine pericardial patch can be used safely and efficiently for the reconstruction of incisional hernias not suitable to direct repair. Further clinical trials are warranted to evaluate the usefulness of this method.

[Changes in surgical therapy of pulmonary hydatid cysts]. / Változások a tüdo echinococcus ciszta sebészi kezelésében.

The lung is the second most common site of hydatid cysts after the liver. The authors analyse retrospectively the results of patients treated with pulmonary hydatid cysts in the past 18 years, considering video-thoracoscopy. Twenty eight patients were treated during this period in 31 cases. Hydatid disease affected only the lung in case of 22 patients, while in 6 cases it was present in the liver and lung simultaneously. Pulmonary hydatid disease affected one side in 24 and both sides in 4 cases. For surgical treatment pericystectomy in one, atypical segment resection in 18, anatomical segmentectomy in three, lobectomy in 7 and video-thoracoscopy in 3 cases were performed without surgical complications. The mean hospital stay was 10.5 days in case of thoracotomies and 8.5 days in case of video-thoracoscopy. There was one recurrence in conventional surgery and reoperation was necessary. After video-thoracoscopy no recurrence was detected. Mean follow-up was 120 months, after video-thoracoscopy it was 20 months. Three patients have uncertain chest pain after thoracotomy, but none has any complaints after video-thoracoscopy. Fifteen patients took mebendazole permanently after the final histological result. According to the authors' practice the indication of lung resections for pulmonary hydatid cysts is limited, in selective cases video-thoracoscopic cystectomy can be a successful treatment of choice.

[Early results after minimal lobectomy for benign nodular goiter]. / Benignus, göbös strumák minimálisan lebenyeltávolítással végzett mútéteinek korai eredményei.

Following traditional operations (enucleation and subtotal resection) for benign nodular goiters recurrences may develop. Reoperations for this condition can cause complications, such as hypoparathyroidism and damage of the recurrent laryngeal nerve. That is why total thyroidectomy is recommended by many specialists in benign thyroid disease. We performed lobectomy on one side, and, if necessary, partial resection on the other side. Lobectomy was performed on one side in 31 cases, with partial resections on the other side in 73 patients. We tried to identify the parathyroid glands and both recurrent laryngeal nerves. Postoperative complications were evaluated. Temporary dysfunction of the recurrent laryngeal nerve was detected in 2.3%, permanent damage in 1.1%. Temporary hypocalcaemia developed in 16.4%, permanent hypocalcemia in 1.9%. Two reoperations were necessary for bleeding. Because of the low postoperative complication rate we recommend this method as an alternative to thyroidectomy for benign nodular goiters. We know that our favourable results can be compared with traditional subtotal resection and thyroidectomy when long term results of thyroid function and data about nodular recurrences will be collected.
