Reverse partial pulmonary resection: a new surgical approach for pediatric pulmonary cysts / 南方医科大学学报

OBJECTIVE@#To evaluate the safety and efficacy of reverse partial lung resection for treatment of pediatric pulmonary cysts combined with lung abscesses or thoracic abscess.@*METHODS@#We retrospectively analyzed the clinical data of children undergoing reverse partial lung resection for complex pulmonary cysts in our hospital between June, 2020 and June, 2021.During the surgery, the patients lay in a lateral position, and a 3-5 cm intercostal incision was made at the center of the lesion, through which the pleura was incised and the fluid or necrotic tissues were removed.The anesthesiologist was instructed to aspirate the sputum in the trachea to prevent entry of the necrotic tissues in the trachea.The cystic lung tissue was separated till reaching normal lung tissue on the hilar side.The proximal end of the striated tissue in the lesion was first double ligated with No.4 silk thread, the distal end was disconnected, and the proximal end was reinforced with continuous sutures with 4-0 Prolene thread.The compromised lung tissues were separated, and the thoracic cavity was thoroughly flushed followed by pulmonary inflation, air leakage management and incision suture.@*RESULTS@#Sixteen children aged from 3 day to 2 years underwent the surgery, including 3 with simple pulmonary cysts, 11 with pulmonary cysts combined with pulmonary or thoracic abscess, 1 with pulmonary cysts combined with tension pneumothorax and left upper lung bronchial defect, and 1 with pulmonary herpes combined with brain tissue heterotaxy.All the operations were completed smoothly, with a mean operation time of 129 min, an mean hospital stay of 11 days, and a mean drainage removal time of 7 days.All the children recovered well after the operation, and 11 of them had mild air leakage.None of the children had serious complications or residual lesions or experienced recurrence of infection after the operation.@*CONCLUSION@#Reverse partial lung resection is safe and less invasive for treatment of complex pediatric pulmonary cysts complicated by infections.

External validation and comparison of different prediction models of postoperative nausea and vomiting in elderly patients with thoracoscopic partial pneumonectomy / 中国实用护理杂志

Objective:To investigate and compare the predictive effects of two postoperative nausea and vomiting (PONV) prediction models in elderly patients with thoracoscopic partial pneumonectomy.Methods:The total of 227 elderly patients who underwent thoracoscopic partial pneumonectomy in Brain Hospital Affiliated to Nanjing Medical University from October 2021 to January 2022 were collected. Apfel risk score and Koivuranta risk score were used to predict the risk of PONV in each patient. The area under the ROC curve was used to evaluate the discrimination ability of the two prediction models; Hosmer-Lemeshow goodness of fit test was used to evaluate the calibration of the two prediction models.Results:Among 227 patients, 74 had PONV, and the incidence of PONV was 32.6%. The area under the ROC curve of Apfel and Koivuranta risk scores in the risk prediction of PONV in elderly patients with thoracoscopic partial pneumonectomy were 0.640 and 0.683 respectively. There was no significant difference between the two ( Z=1.54, P>0.05). The Hosmer-Lemeshow goodness of fit test showed that the accuracy of the two models in predicting PONV risk in elderly patients with thoracoscopic partial pneumonectomy was better ( P>0.05). Conclusions:The difference between the two models in PONV risk prediction in elderly patients with thoracoscopic partial pneumonectomy is general, Koivuranta model is more suitable for predicting PONV in elderly patients with thoracoscopic partial pneumonectomy, but its applicability is still insufficient.

The predictive value of stair climbing test combined with arterial blood gas analysis on postoperative complications in lung cancer patients with limited pulmonary function / 中华胸心血管外科杂志

Objective:To evaluate the predictive value of stair climbing test combined with arterial blood gas analysis on postoperative complications in lung cancer patients with limited pulmonary function.Methods:A total of 1 231 hospitalized lung cancer patients with limited pulmonary function dating from August 2012 to August 2020 were retrospectively reviewed. Included in the cohort were 766 of patients who underwent stair climbing test(SCT) preoperatively and completed data collection. Patients were grouped according to their general condition, past medical history, surgical approach, pulmonary function test(PFT) and SCT results. Comparison of the postoperative cardiopulmonary complication rates were made between different groups, and independent risk factors were identified.Results:A total of 182 cardiopulmonary-related complications occurred in 144 cases, accounting for 18.8% of the entire cohort. Perioperative mortality rate was 0.9%(7/766). The rate of postoperative cardiopulmonary complications was significantly different between the groups stratified by gender, age, smoking index, PFT index(FEV1%, DLCO%), SCT results(height achieved, speed, changes in heart rate and oxygen saturation of the arteries before and after the test), ASA score, surgical approach(VATS/Open), resection range(Lobectomy/Sublobectomy), anesthetic duration, blood loss volume, etc. Logistic regression analysis showed that only height achieved( P<0.001), changes in heart rate( P<0.001), changes in oxygen saturation of the arteries( P=0.001), resection range( P=0.006) and anesthetic duration( P=0.025) were independent risk factors for cardiopulmonary-related complications in lung cancer patients with limited pulmonary function. Conclusion:The stair climbing test combined with arterial blood gas analysis could be used as a preoperative screening method for lung cancer patients with limited lung function and may have a predictive value for postoperative cardiopulmonary-related complications.

OBJECTIVE: To investigate the feasibility and safety of simultaneous liver section combined with pulmonary wedge resection via the trans-diaphragmatic approach in patients of synchronous liver and lung metastases. METHODS: The clinical data of 3 patients of synchronous liver and lung metastases who underwent simultaneous liver section combined with pulmonary wedge resection via the trans-diaphragmatic approach at Peking University Cancer Hospital between May 2017 and June 2017 were retrospectively analyzed. RESULTS: All liver and lung metastases of 3 patients were successfully resected. Operation time for liver resections were 82, 50 and 43 min, while blood losses were 400, 150 and 200 mL respectively. Meanwhile, operation time for pulmonary resections were 45, 60 and 36 min, and blood losses were 10, 30 and 5 mL respectively. Neither perioperative death nor severe complication occurred. CONCLUSION: Simultaneous liver resection combined with pulmonary wedge resection via the trans-diaphragmatic approach is a safe technique for the patients with resectable synchronous liver and lung metastases

Comparison of laryngeal mask anesthesia and intubation anesthesia under spontaneous ventilation in uniportal video-assisted thoracoscopic surgery / 实用医学杂志

Objective To assess the feasibility of laryngeal mask anesthesia under spontaneous ventilation in pulmonary resection with uniportal video-assisted thoracoseopic.Methods Forty patients with pulmonary masses were randomized into two groups(n =20 in each group) to undergo pulmonary resection with uniportal videoassisted thoracoscopic,full implementation of thoracoscopic lobectomy and mediastinal lymph node dissection.Patients in two groups were induced by intravenous anesthesia,and the skin of the fifth intercostal space were infiltrated with ropivacaine.Patients in two both groups were maintained by intravenous ancsthesia and sevoflurane anesthesia.Muscle relaxants were administered in endotracheal inmbation group but not in the LMA group.Patients in the LMA group and tracheal intubation group underwent with spontaneous breathing and one-lung ventilation respectively.Results No significant differences were found in surgery time,intraoperative lowest SpO2,preoperative PaCO2,1-h postoperative blood gas analysis between the two groups.The anesthesia induction time,extubation time,and the stay time for the recovery of anesthesia and postoperative hospital stay were significantly shorter than those in the tracheal intubation group.The increments in MAP and HR after intubation operation were smaller than those in the LMA group.The total dosage of sulfentanyl and propofol per kg in the LMA group were significantly less than those in the control group.The PaCO2 after pulmonary resection and the intraoperative maximum level of PETCO2 in the former group were significantly higher than those in the tracheal intubation group,however the incidence of throat discomfort and the hospitalization cast were significantly decreased.Conclusion In view of patient rehabilitation and in hospitalization cast,laryngeal mask anesthesia under spontaneous ventilation in uniportal video-assisted thoracoscopic surgery was better than the procedure performed under intubation anesthesia.

Clinical analysis of the relationship between chemotherapy after pneumonectomy and bronchopleural fistula / 局解手术学杂志

Objective To evaluate the relationship between chemotherapy after pulmonary resection and the incidence rate of bron-chopleural fistula. Methods 246 patients who received pulmonary resection in our hospital from January 2009 to June 2014 were chosen, and they were divided into the chemotherapy group and the non-chemotherapy group. The 138 patients in the chemotherapy group received chemotherapy one month after resection while the other 108 in the non-chemotherapy group did not. Bronchopleural fistula of the two groups were diagnosed and analyzed in order to evaluate the relationship between chemotherapy after pulmonary resection and incidence rate of bron-chopleural fistula. Results There were 12 cases of bronchopleural fistula in the chemotherapy group with an incidence rate of 8. 70%, while there were 2 cases of bronchopleural fistula in the non-chemotherapy group with an incidence rate of 1. 85%. The difference between the two groups is statistically significant (P<0. 05). Conclusion Chemotherapy after pulmonary resection will increase the incidence rate of bron-chopleural fistula.

Repercusión de las complicaciones mayores posoperatorias en pacientes operados de tórax / Repercussion of major postoperative complications in patients undergoing thoracic surgery

Introducción: las complicaciones en la cirugía de tórax (pulmón, mediastino, esófago) se han asociado con un incremento en la morbilidad y la mortalidad. No se conoce cuál es la influencia de estas en la evolución de estos pacientes. Objetivo: determinar la influencia de las complicaciones mayores posoperatorias en la evolución a corto plazo de los pacientes sometidos a cirugía tóraco-mediastinal-esofágica. Métodos: se realizó un estudio de cohorte retrospectivo. De las bases de datos de la Unidad de Cuidados Intensivos y hospitalaria, entre marzo y octubre del 2013, se estudiaron a los enfermos sometidos a cirugía tóraco-mediastinal-esofágica, se identificó la ocurrencia de complicaciones mayores posoperatorias durante la estadía hospitalaria. Se precisó el tipo de complicación y su influencia en la evolución de los enfermos. Resultados: de 50 pacientes analizados, con una mediana de edad de 58,50 años (RIQ 48-65 años), a 30 (60 por ciento) se les realizó resección pulmonar, a 11 (22 por ciento) cirugía torácica sin resección pulmonar (mediastino y otras) y la cirugía esofágica se le practicó a 9 sujetos (18 por ciento). En 10 pacientes (20 por ciento) se presentó alguna complicación mayor posoperatoria, con 13 complicaciones en total, 7 de carácter médico (53,85 por ciento) y 6 quirúrgicas (46,15 por ciento). Las complicaciones más frecuentes fueron la hemorragia posoperatoria (40 por ciento), la neumonía nosocomial (20 por ciento) y las arritmias cardiacas (20 por ciento). Murieron 4 pacientes, fundamentalmente por complicaciones médicas. Las complicaciones mayores posoperatorias disminuyeron las probabilidades de alta hospitalaria (HR de 0,376 [95 por ciento IC: 0,173-0,815]; p= 0,013). Conclusiones: la frecuencia de las complicaciones mayores posoperatorias en la cirugía tóraco-mediastinal-esofágica fue relativamente alta en esta serie. La mortalidad fue más frecuente en los pacientes con complicaciones médicas. Las complicaciones mayores incrementaron significativamente la estadía en cuidados críticos y hospitalarios(AU)

Surgical repair of early bronchopleural fistula after pulmonary resection / 中华胸心血管外科杂志

Objective Bronchopleural fistula (BPF) is a common but potentially lethal complication after pulmonary resection.Currently,there is still controversy over the appropriate management strategy for BPF,especially when pleural space contamination develops.The purpose of this study was to evaluate the efficacy and safety of surgical repair fistulas combined with pedicled muscle flaps coverage in patients with early BPF after pulmonary resection based on our experience with 23 cases.Methods The clinical data for 23 patients who underwent surgical repair of early BPF from January 1999 to December 2010 at our hospital were reviewed.Thirteen patients had undergone a prior pneumonectomy and 10 patients had undergone a prior lobectomy.BPF occurred from postoperative day 5 to40 (mean postoperative day 21 ).Nine patients had a contaminated pleural space.After BPF was clearly diagnosed,prompt closed pleural drainage was instituted,followed by surgical repair of BPF.Four patients underwent a direct suture repair of fistula,ten patients underwent stump revision and suture closure,seven patients underwent stump revision and bronchoplasty or carina plasty,and a pedicled muscle flap was sewn to the edges of the fistula in two patients.The stump was covered with various muscle flaps,including interostal muscle flap in five cases,latissimus dorsi muscle flap in ten cases,serratus anterior muscle flap in six cases,and erector spinae muscle flap in two cases.Postoperatively,the pleural space was routinely irrigated and drained.Results No intraoperative or early postoperative death occurred.Four patients developed severs complications,including respiratory failure in two cases,pulmonary embolism in one case,and empyema in one case.All four cases recovered well after treatment.The mean duration of hospitalization was 33 days (range 8 - 120 days ).Surgical repair of BPF was successful in 21 cases (91.3％) but failed for 2 patients..BPF recurrence developed in only one patient two years postoperatively due to stump recurrence.He died of extensive metastatic disease 2 years after BPF recurrence.Conclusion Excellent results can be achieved by early surgical repair combined with stump pedicled muscle flaps coverage in patients with BPF who can tolerate reoperation,even if they have a contaminaled pleural space.

Manejo quirúrgico del cáncer de pulmón. Hechos y algunas reflexiones / Surgical approaches to lung cancer. Facts and some reflections

El carcinoma broncogénico de células no pequeñas (CBCNP) en etapas I y II es tributario de resección completa, pero cada vez existe más evidencia de que la terapia de inducción preoperatoria y la adyuvancia posoperatoría pueden prolongar la sobrevida de enfermos en etapas IB y II. Algunos enfermos en la etapa IIIA debe recibir inducción y revalorar el mediastino por fusión TC/PET o remediastinoscopía antes de planear resección. Las etapas IIIB y IV no son operables, excepto casos muy seleccionados. Se hacen reflexiones a propósito del acceso de los enfermos de países en desarrollo a los nuevos avances médicos, farmacológicos y tecnológicos, del control del tabaquismo y de algunos aspectos éticos relacionados con el tratamiento médico y la cirugía del CBCNP.

Stage I and II non-small cell lung cancer (NSCLC) should be resected, but there is mounting evidence for the use of preoperative induction and postoperative adjuvant therapy in stages IB and II, as being able to prolong life. Some patients in stage IIIA should undergo induction therapy, and then have re-staging of the mediastinum by CT/PET or redo mediastinoscopy before considering resection. Stages IIIB and IV are non-surgical, except very selected cases. Reflections are made regarding the control of cigarette smoking, the difficult access of patients from developing countries to the recent costly medical, pharmacological and technical advances; reflections are also made related to some ethical issues regarding medical and surgical treatment of NSCLC.

Pulmonary Resections - Jammu Experience

Ten year registry of patients who underwent pulmonary resections at CTVS section of Govt Medical College Jammu is being presented. The cohort consisted of 94 patients operated between1994-2004. Males outnumbered females in this series Most number (30/94) of patients presented in the 4th decade. Etiology wise, Infective lung diseases were the leading causes leading to pulmonary resections, this included bronchiectasts with 32/94, chronic empyema in6/94 and middle lobe syndrome in one patient. Lung tumors were the causative factors in 20 and post tuberculosis destroyed lung in 17 cases. Two patients presented with intralobar lung sequestrations and one each with pulmonary blastoma and teratoma. The spectrum of resections included right pneumonectomy in19/94 followed by right and left lower lobectomies in 18 each. Thirteen patients underwent left pneumonectomy, 7 bilobectomy and 4 lingulectomy respectively. The mortality in our series was 6/94,20 patients had wound infection, 9 had bronchopleural fistula and 3 postoperative space infections.3 patients were reexplored because of hemorrhage in immediate postoperative period. Diagnostic video assisted thoracoscopy has been started and was employed in 6 patients.

Video-assisted thoracoscopic pulmonary resection under local anesthesia / 中国微创外科杂志

Objective To study the feasibility of video-assisted thoracoscopic (VAT) minor pulmonary resection under local anesthesia. Methods From February to December 2000,8 patients (6 cases of peripheral pulmonary nodules,2 cases of respiratory insufficiency and radiographic pulmonary infiltrate)were operated on through video-assisted thoracoscopy under local anesthesia. Results Except 1 case was converted to general anesthesia and performed minithoracotomy to resect pulmonary coin lesion due to pleural adhesion,other 7 patients underwent VAT-pulmonary wedge ressction under local anesthesia and definitive diagonosis.(3 with tuberculosis,1 with metastatic adenocarcinoma,1 with inflammatory pseudotumor and 2 with pulmonary fibrosis)were obtained.The duration of the procedures was from 40 to 200 min. Spontaneous breathing and hemodynamics were maintained well during the operation.There was neither severe postoperative complications nor mortality.The postoperative hospitalized days were 2～5 days with a mean of 3 days. The average medical fee for pulmonary wedge ressction using our procedure was 5400 RMB. Conclusions VAT-minor pulmonary resection can be performed safely under local anesthesia.

A Case of Resection of Pulmonary Metastatic Choriocarcinoma in Drug-Resistant Patient / 대한산부인과학회잡지

Pulmonary metastasis occurs frequently in patients with gestational choriocarcinoma and most of these patients achieve remission with chemotherapy alone. Thus, the indications for surgical intervention are limited, but in appropriately selected patients, resection of a chemotherapy-resistant lung lesion can be curative. We have experienced that pulmonary metastatic choriocarcinoma in a drug-resistant patient was cured by pulmonary resection. So we report this case with a brief review of literatures.

Pulmonary Resection in the Treatment of Multidrug-Resistant Tuberculosis / 결핵

BACKGROUND: Recent outbreaks of pulmonary disease due to drug-resistant strains of Mycobacterium Tuber-culosis have resulted in significant morbidity and mortality in patients worldwide. We reviewed our experience to evaluate the effects of pulmonary resection on the managenent of multidrug-resistant tuberculosis. METHOD: A retrospective review was performed of 41 patients undergoing pulmonary resection for multidrug-resistant tuberculosis between January 1993 and December 1997. We divided these into 3 groups according to the radiologic findigs : (1) patients who have reasonably localized lesion ( Localized Lesion Group ; LLG) (2) patients who have cavitary lesion after pulmonary resection on chest roentgenogram (Remained Cavity Group : RCG). (3) patients who have Remained infiltrative lesions postoperatively (Remained infiltrative group : RIG). We evaluated the negative conversion rate after resection and overall response rate of the groups. Then they were compared with the results of the chemotherapy on the multidrug-resistant tuberculosis which has been outcome by Goble et al. Goble et al reported that negative conversion rate was 65% and overall response rate, 56% over a mean period of 5.1 months. RESULTS: Seventy five point six percent were men and 24.4% woment with a median age of 31 years (range, 16 to 60 years). Although the patients were treated preoperatively with multidrug regimens in an effort to reduce the mycobacterial burden, 22 of 41 were still sputum culture positive at the time of surgery. 20 of 22 patients (90.9%, p<0.01) responded which is defined as negative sputum cultures within 2 months postoperative. Of 26 patients with the sufficient follow up data, 19 have Remained sputum culture negative for a mean duration of 25.7 months (73.1%, p<0.05). The bulk of the disease was manifest in one lung, but lesser amounts of contralateral disease were demonstrated in 15, consisted of 8 in RIG and 7 in RCG, of 41. 12 of 12 patients (100%, p<0.01) who were sputum positive at the time of surgery in LLG converted successfully. 14 of 15 patients (93.3%, p<0.05) with the follow up have completed treatment and not relapsed for a mean period of 25.7 months. The mean length of postoperative drug therapy off LLG was 12.2 months. In RIG, postoperative negative conversion rate was 83.3% which was not significant statistically. There was a statistical significance in overall response rate (100%, p<0.05) of RIG for a mean period of 24.4 months with a mean length of postoperative chemotherapy, 11.8 months. In RCG a statistically lower overall response rate (14.3%, p<0.01) has been revealed for a mean duration of follow up, 24.2 months. A negative conversion rate of RCG was 75% which was not significant statistically. CONCLUSION: Surgery plays an important role in the management of patients with multidrug-resistant Mycobacterium tuberculosis infection. Aggressive pulmonary resection should be performed for resistant Mycobacterium tuberculosis infection to avoid treatment failture or relapse. Especially all cavitary lesions on preoperative chest roentgenogram should be resected completely. If all them could not be resected perfectly, you should not open the thorax.

The use of multi-slice spiral CT to predict bronchial involvement from central lung cancer / 中华胸心血管外科杂志

Objective: To assess the accuracy of multi-slice spiral CT (MSCT) with imaging reconstruction in judging bronchial involvement from central lung cancer. Methods: MSCT was done in 30 patients who were diagnosed as central lung cancer. Images of bronchi related to lobectomy or pneumonectomy were reconstructed by means of imaging processing techniques. Then the relation between tumor and bronchus was assessed prospectively with both axial CT and CT with imaging reconstruction in comparison with subsequent pathologic and surgical findings. Results: All 30 patients underwent thoracotomy, lobectomy or pneumonectomy. Total 66 bronchi were studied. Compared with axial CT images, CT with imaging reconstruction was better in judging the relation of bronchus and tumor in comparison with subsequent pathologic and surgical findings (0.01

Clinical Evaluation of Surgical Resection of Pulmonary Tuberculosis / 결핵

BACKGROUND: In spite of initial intensive and long-term chemotherapy for pulmonary tuberculosis, many problems remain in the treatment of the residual lesion. The role of surgical intervention for pulmonary tuberculosis is getting rid of such residual lesion of pulmonary tuberculosis to support the healing process and to induce bacteriologically negative conversion in the end. METHOD: We experienced 30 cases of pulmonary resection for pulmonary tuberculosis from Aug. 1994 through Apr. 1995 in National Masan Tuberculosis Hospital. We conducted retrospective study to analyze several variables for the cases. RESULTS: 1) The ratio between male and female was 4:l(male 24, female 6) and the age of peak incidence was in 3rd and 4th decades. 2) Indications for pulmonary resection in the radiographic findings were cavitary lesions of 19 cases(63.3%), destroyed one side of 8 cases(26.7%) and destroyed one lobe of 3 cases(10%). 3) 16 of 20 cases with unilateral lesions and all of 10 cases with bilateral lesions on chest X-ray films showed AFB positive on preoperative sputum smears. 14 cases(87.5%) of unilateral lesions and 9 cases(90%) of bilateral ones were converted into AFB negative postoperatively. Negative conversion rates of pneumonectomy and lobectomy cases were 100% and 85.7%, respectively. 4) Preoperative combined disease was 3 cases(10%) of DM and postoperative complications were 2 cases(6.7%) of dead space and no death. CONCLUSION: Chemotherapy only has some limitation in treatment of all tuberculosis. So, surgical intervention for pulmonary tuberculosis is an effective method as partner of chemotherapy.
