【Objective】 To explore the safety and efficacy of a modified one-piece posterior laparoscopic total nephroureterectomy with cystic sleeve resection in the treatment of upper urinary tract uroepithelial carcinoma (UTUC). 【Methods】 A total of 24 patients treated during Jan. and Jun. 2022 were involved, including 16 males and 8 females, aged 62 to 90 (average 73) years. The UTUC was in the left side in 15 cases, and in the right side in 9 cases. There were 10 cases of renal pelvis tumor, 6 cases of upper ureteral tumor and 8 cases of lower ureteral tumor. 【Results】 All operations were successful without conversion to open surgery. The operation time ranged from 60 to 100 minutes, average (71.25±9.80) minutes. The intraoperative bleeding volume was 20 to 200 mL, average (30.03±8.13) mL. No significant intraoperative or postoperative complications occurred. The postoperative hospital stay was 4 to 7 days, average (5.83±1.44) days. Bladder perfusion chemotherapy was performed after surgery. 【Conclusion】 The modified one-piece posterior laparoscopic total nephroureterectomy plus cystic sleeve resection for UTUC is an effective and feasible procedure with satisfactory tumor control, which is worth further promotion in clinical practice.

Experience of Thoracotomy and Robot-assisted Bronchial Sleeve Resection after Neoadjuvant Chemoimmunotherapy for Local Advanced Central Lung Cancer / 中国肺癌杂志

BACKGROUND@#Immunoneoadjuvant therapy opens a new prospect for local advanced lung cancer. The aim of our study was to explore the safety and feasibility of robotic-assisted bronchial sleeve resection in patients with locally advanced non-small cell lung cancer (NSCLC) after neoadjuvant chemoimmunotherapy.@*METHODS@#Data of 13 patients with locally advanced NSCLC that underwent bronchial sleeve resection after neoadjuvant chemoimmunotherapy during August 2020 and February 2021 were retrospectively included. According to the surgical methods, patients were divided into thoracotomy bronchial sleeve resection (TBSR) group and robot-assisted bronchial sleeve resection (RABSR) group. Oncology, intraoperative, and postoperative data in the two groups were compared.@*RESULTS@#The two groups of patients operated smoothly, the postoperative pathology confirmed that all the tumor lesions achieved R0 resection, and RABSR group no patient was transferred to thoracotomy during surgery. Partial remission (PR) rate and major pathological remissions (MPR) rate of patients in the TBSR group were 71.43% and 42.86%, respectively. Complete pathological response (pCR) was 28.57%. They were 66.67%, 50.00% and 33.33% in RABSR group, respectively. There were no significant differences in operative duration, number of lymph nodes dissected, intraoperative blood loss, postoperative drainage time and postoperative hospital stay between the two groups, but the bronchial anastomosis time of RABSR group was relatively short. Both groups of patients had a good prognosis. Successfully discharged from the hospital and post-operative 90-d mortality rate was 0.@*CONCLUSIONS@#In patients with locally advanced central NSCLC after neoadjuvant chemoimmunotherapy can achieve the tumor reduction, tumor stage decline and increase the R0 resection rate, bronchial sleeve resection is safe and feasible. Under the premise of following the two principles of surgical safety and realizing the tumor R0 resection, robot-assisted bronchial sleeve resection can be preferred.

ideo-assisted thoracoscopic sleeve lobectomy in the treatment of central non-small cell lung cancer: A retrospective cohort study / 中国胸心血管外科临床杂志

@#Objective    To evaluate the efficacy of video-assisted thoracoscopic sleeve lobectomy in the treatment of central non-small cell lung cancer. Methods    The clinical data of 105 patients with central non-small cell lung cancer who underwent sleeve lobectomy surgery in the Second Hospital of Shanxi Medical University and Shanxi Cancer Hospital from December 2014 to December 2019 were retrospectively analyzed, including 83 males and 22 females, with an average age of 57.4 (32.6-77.8) years and weight of 62.5 (52.4-79.1) kg. Thirty-five patients received video-assisted thoracoscopic sleeve lobectomy (a group A), and 70 patients received traditional thoracotomy sleeve lobectomy (a group B). The operation time, intraoperative blood loss, number of lymph node dissection, postoperative complication rate, early postoperative mortality, total thoracic drainage volume at 24 hours, time of indwelling chest tube after operation, pain score at 24 hours after operation, postoperative hospital stay, postoperative short-term (1 month, 6 months and 1 year) quality of life score and postoperative 3-year survival rate of two groups were compared. Results    There was statistical difference in the operation time (228.1±24.7 min vs. 175.0±23.7 min, P=0.02), postoperative complication rate (28.6% vs. 34.3%, P=0.04), postoperative pain score at 24 h (3.6±3.5 points vs. 5.9±2.0 points, P=0.03) and postoperative indwelling chest tube time (5.0±2.9 d vs. 8.4±2.1 d, P=0.04) between the two groups. There was no statistical difference in the intraoperative blood loss (182.5±36.9 mL vs. 189.8±27.5 mL, P=0.34), number of lymph node dissections (11.1±2.6 vs. 12.3±1.9, P=0.49), early postoperative mortality (2.9% vs. 4.3%, P=0.31), total thoracic drainage volume at 24 h after surgery (346.8± 91.1 mL vs. 329.8±101.4 mL, P=0.27), postoperative hospital stay (7.9±4.2 d vs. 8.5±3.4 d, P=0.39) and 3-year postoperative survival rate (68.6% vs. 72.9%, P=0.82) between the two groups. Conclusion    Video-assisted thoracoscopic sleeve lobectomy for the treatment of central non-small cell lung cancer is safe and feasible. Compared with traditional thoracotomy for sleeve lobectomy, fewer postoperative complications occur, body recovers faster and the quality of life is higher within the postoperative 6 months. Besides, the 3-year survival rate can achieve similar oncological prognosis results.

Bronchial Carcinoid in a Child: A Case Report.

Bronchial carcinoid (BC) make up 80-90% of a group of lung tumors formerly called “bronchial adenomas,” which also included adenoid cystic carcinoma and mucoepidermoid carcinoma; hence, their actual incidence was not accurately known. It is a rare entity in the pediatric population where metastatic lung tumors greatly outnumber primary lung tumors. BC account for 2-5% of all lung neoplasms in adults but are the most common primary lung neoplasm of childhood, accounting for 80% of malignant bronchopulmonary neoplasms in children. We have presented a case of left BC in an 11-year-old boy, with a short review of literature, and discussed the management. We have discussed the surgical procedure in detail, pointing out the possible pitfalls and their management.

Carcinoma mucoepidermoide bronquial: Reporte de caso y revisión bibliográfica / Bronchial Mucoepidermoid Carcinoma: A Case Report and Literature Review

Los tumores mucoepidermoides que asientan en la tráquea y árbol bronquial son neoplasias infrecuentes. Representan menos del 5% de las neoplasias pulmonares. Se presenta un paciente de sexo masculino, de 29 años de edad, que consultó por presentar tos con expectoración asociado a registros febriles de 8 meses de evolución, sin pérdida de peso ni hemoptisis. La TAC reveló una atelectasia del lóbulo superior izquierdo y una imagen de aspecto polipoideo de 16 mm localizada en el bronquio fuente izquierdo. En la fibrobroncoscopía se observó una tumoración polipoidea a 18 mm de la bifurcación traqueal. Se realizó una resección en manguito con anastomosis bronquial termino-terminal. El estudio anatomopatológico de la pieza informó como carcinoma mucoepidermoide bien diferenciado. El paciente presentó una buena evolución postoperatoria con un egreso hospitalario al quinto día.

Mucoepidermoid tumors of the trachea and bronchi are uncommon neoplasms, and represent less than 5% of all pulmonary neoplasms. We present a 29-year-old patientwho was referred to our hospital with complaints of cough with expectoration together with intermittent fever during 8 months without weight loss or hemoptysis. The CT scan of the chest revealed left upper lobe atelectasis and a polypoid mass in the left main bronchus with a diameter of about 16 mm. Bronchoscopy revealed a polypoidendobronchial tumor at 18 mm from tracheal bifurcation. The patient underwent a sleeve resection with bronchial anastomosis. The hystopathological analysis of post-operative material confirmed the diagnosis of a low grade, well-differentiated mucoepidermoid carcinoma. There were no complications during the post-operative period and the patient was discharged from hospital on the fifth day after surgery.

Bronchial Sleeve Resection for Lung Cancer Preoperative Empyema.

Surgical management of the cancer with empyema has rarely been reported in the literature because few of such cases are operable. Many patients might be misevaluated because of the incorrect staging associated with an acute or sub-acute infection. Even in the presence of an operable tumor mass; surgeons behave timid to these patients because of the possibility of infective postoperative complications. The balance between expected benefits and possible risk of surgical intervention is also important. If it is indicated, by the time pleural empyema is restored, procedures such as resection and even bronchoplasty should be performed. 59-years old patient with squamous cell carcinoma that completely obstructed left basal segments and caused to empyema. A thoracic catheter was inserted. Multiple pleural irrigations were done and proper antibiotherapy. Pathologic diagnosis of pleural fluid and pleural biopsy were benign. Pleural cultures were negative and amount of empyema fluid volume has decreased within two months. Positron emission tomography (PET) revealed a 2.5 cm sized left infrahilar tumor, right paratracheal, prevascular and subcarinal lymph nodes and non-homogeneous increased pleural activity. Mediastinal lymph nodes were evaluated as reactive with mediastinoscopy. Left lower lobectomy and lingulectomy were performed with bronchial resection and pathologic stage was 2A (T1bN1MO).

Clinical evaluation of non small-cell luny cancer operated by autofluorescence bronchoscopy / 中国基层医药

ObjectiveTo explore the role of autofluorescence bronchoscopy in lung cancer operation and the meaning of choice lung cancer operation mode.MethodsTo retrospectively analyze 32 non-small cell lung cancer patients.Before lung cancer operation,white light bronchoscopy (WLB) and autofluorescence bronchoscopy (AFB) had been done routinely.Compared the different invasive tumor conditions by WLB and AFB,operation modes were decided by the edge of the tumor which were proved by biopsy pathology.ResultsIn 32 cases,19 cases underwent pulmonary lobectomy.One case underwent carinal resection and reconstruction.8 cases underwent sleeve lobectomy.4 cases underwent other therapy because of tumor airway metastasis.In 8 cases which underwent sleeve lobectomy,3 ca ses were found by WLB and AFB together,5 cases were found only by AFB.In 4 cases who had no operation chance,2 cases were found by WLB and AFB together,2 cases were only by AFB.The sensitivity for the detection of bronchial premalignant lesions was extremelyhigher withthe addition of AFB than WLBalone ( P ＜ 0.05 ).ConclusionAutofluorescence bronchoscopy is a safe and efficient technique which could improve the sensitivity of diagnosis in lung cancer than WLB.It is important to select operation mode.

A Case of Basal Cell Carcinoma of External Auditory Canal

Malignant tumor originated from external auditory canal (EAC) is very rare with an annual incidence of around 1 per million. Pathologically, squamous cell carcinoma is incidentally most common, and adenoid cystic carcinoma, basal cell carcinoma, and melanoma follow in decreasing order. Due to the rarity of malignant tumor of EAC, there is no widely accepted treatment modality yet. But basal cell carcinoma, known to be less aggressive tumor, can be removed with a minimal safety margin and have better treatment results. Recently we experienced a case of basal cell carcinoma in the EAC, confined in the cartilaginous portion of EAC, presenting with intermittent otorrhea for several years. The patient was treated with a sleeve resection of the EAC with a safety margin reconstructed with a split-thickness skin graft. No tumor recurrence or complication was noted in the first postoperative year.

Extended Sleeve Lobectomy for Tuberculous Bronchial Stenosis: A case report / 대한흉부외과학회지

Tuberculosis involving the central airway occasionally results in diffuse stenosis in the distal trachea and main bronchus. When the stenosis is more limited to the main bronchus, sleeve resection can be performed with high likelihood of a good result. Bronchial stenosis limited to 2 cm is considered favorable for bronchial sleeve resection. However, a longsegment stenosis may make sleeve resection difficult or impossible, and pneumonectomy or therapeutic bronchoscopy may be performed. An extended sleeve lobectomy is a procedure to remove more than one lobe using a bronchoplasty technique and its applications to the patients with locally advanced lung cancer were reported. We performed an extended sleeve lobectomy in a patient with tuberculous bronchial stenosis involving the right main bronchus, bronchus intermedius, right middle lobar bronchus and right lower lobar bronchus, and report this case with review of literatures.

Results of Bronchial Sleeve Resection for Primary Lung Cancer / 대한흉부외과학회지

BACKGROUND: It is known that long-term survival rate in patients underwent bronchial sleeve lobectomy for primary lung cancer is at least equal to that in patients underwent pneumonectomy, and bronchial sleeve lobectomy is performed in patients with suitable tumor location even in patients have adequate pulmonary function. Sleeve pneumonectomy is performed when carina was invaded by tumor or tumor location was near to the carina. We performed this study to know our results of sleeve resection for primary lung cancer. MATERIAL AND METHOD: We analyzed retrospectively the medical records of 45 patients who underwent sleeve lobectomy or sleeve pneumonectomy for primary lung cancer by one thoracic surgeon from May 1990 to July 2003 in Department of Thoracic & Cardiovascular Surgery, College of Medicine, Kyung Hee University. Follow-up loss was absent and last follow-up was performed in April 5, 2005. Kaplan-Meyer method and log-lank test were used to know long-term survival rate and p-value. RESULT: Mean age was 60 years old and male to female ratio 41:1. Histologic types were squamous cell carcinoma were 39, adenocarcinoma were 4, and others were 2 patients. Pathologic stages were I 14, II 14, and III 17 patients. Nodal stages were N0 23, N1 13, and N2 9 patients. Types of operation were sleeve lobectomy 40 and sleeve pneumonectomy 5 patients. Operative mortality was 3 patients and its cause was respiratory complications. Early complications were pneumonia 4, atelectasis 8, air leakage more than 7 days 6, and atrial fibrillation 4 patients. In 19 patients tumor was recurred. Local recurrence was 10 and systemic metastasis was 9 patients. Overall 5, 10-year survival rate were 54.2%, 42.5%. The 5, 10-year survival rates according to the pathologic stage were 83.9%, 67.1% in stage I, 55%, 47.1% in II, 33.3%, 25% in III, and significance difference was present between stage I and III. The 5, 10-year survival rate according to the lymph node involvement were 63.9%, 54.6% in N0, 53.8%, 46.5% in N1, 28.5%, 14.2% in N2, and significance difference was present between N0 and N2. CONCLUSION: Because bronchial sleeve lobectomy for primary lung cancer could be performed safely and shows acceptable long-term survival rate, it could be considered primary in case of suitable tumor location if complete resection is possible. Although sleeve pneumonectomy for primary lung cancer shows somewhat high operative mortality rate, it could be considered in view of curative treatment.

Bronchial-pulmonary arterial sleeve resection and reconstruction in the treatment of central non-small cell lung cancer / 中国医师进修杂志

Objective To evaluate the indications and surgical procedure of bronchial-pulmonary arterial sleeve resection for patients with centrally located non-small cell lung cancer (NSCLC),and to prevent complications. Methods From October 1987 to December 2004, 96 cases of central NSCLC were treated with bronchial-pulmonary arterial sleeve resection and reconstruction. The results were retrospectively analyzed. Results The complication rate was 19.8%(19/96), the mortality rate in 30-day postoperation was 3.1%(3/96), the overall 1, 3, 5 year survival rates were 82.6%(76/91), 57.8%(37/64) and 39.1%(18/46) respectively. Conclusion Bronchial-pulmonary arterial sleeve resection and reconstruction in the treatment of patients with central NSCLC can not only maximize preservation of functional pulmonary parenchyma and improve the quality of life, but also provide an opportunity for those patients with poor pulmonary function to receive surgical resection of the tumor.

Comparison the efficacy between bronchial sleeve resection and bronchial wedge resection in the treatment of lung cancers / 中国基层医药

Objective To compare the efficacy between bronchial sleeve resection and bronchial wedge resection in the treatment of lung cancers.Methods The clinic datas of bronchial sleeve resection in 38 cases and bronchial wedge resection in 24 cases were analyzed,comparing the incindence of the fistulas on the anastomotic sites,early death,carcinoma cells on the bronchial edges,cancer recurrence on the anastomotic sites and survival rates between two groups.Results In the group of the bronchial sleeve resection,2 cases underwent the fistulas on the anastomotic sites,3 cases suffered death in the early period,2 cases residued carcinoma cells on the bronchial edges,1 case had scar hyperplasia on the anastomotic sites,1 case had cancers recurrence on the anastomotic sites.1 year,3 years,5 years survival rates were respectively 87.5%(28/32),60%(15/25),40%(4/10).In the group of the bronchial wedge resection,no cases underwent the fistulas on the anastomotic sites,2 cases suffered death in the early period,5 cases residued carcinoma cell on the bronchial edges,4 cases found scar hyperplasia on the anastomotic sites,3 cases having cancer recurrence on the anastomotic sites.1 year,3 years,5 years survival rates were respectively 85.7%(18/21),53.3%(8/15),42.9%(3/7).Conclusion Compared with bronchial sleeve resection in the treatment of lung cancers,the bronchial wedge resection increases the incindence of carcinoma cell on the bronchial edges and cancer recurrence on the anastomotic sites,but there is no difference in survival rate between them.

Necrotizing Bronchial Aspergillosis: A case report / 대한흉부외과학회지

Necrotizing bronchial aspergillosis usually occurs in the immumocompromised host. Aspergillus invades bronchial epithelium and forms endobronchial mass or endobronchial stenosis. A 78-year-old male patient with diabetus mellitus complaining of dyspnea and cough was admitted to our hospital. Plain chest X-ray and chest computed tomogram showed a large endobronchial mass and total collapse of left upper lobe of the lung. Bronchoscopic biopsy of the endobronchial mass revealed chronic inflammation. To confirm the endobronchial mass, we performed sleeve lobectomy of left upper lobe of the lung. Histologically the mass was diagnosed as necrotizing bronchial aspergillosis. We report a case of necrotizing bronchial aspergillosis in an elderly man who has diabetus mellitus with review of the literature.

Left Sleeve Pneumonectomy Via Sequential Bilateral Thoracotomy in Carinal Squamous Cell Carcinoma: One case report / 대한흉부외과학회지

Sleeve pneumonectomy can be a method of treatment in a selected patient with bronchogenic carcinoma involving carina. A 64 years old male with a history of mitral valve replacement via midsternotomy 13 years ago and resection of papilloma of the vocal cord 2 years ago. The patient was admitted due to blood-tinged sputum. Bronchoscopy and computerized tomogram of the chest revealed 3.5 cm mass at lower margin of the trachea and totally obstructing the left main bronchus. A biopsy revealed squamous cell carcinoma. He underwent left sleeve pneumonectomy through sequential bilateral thoracotomy without cardiopulmonary bypass, and the pathologic stage was T4N0M0 stage IIIB. The patient is being followed through the outpatient clinic in good general condition.

Capillary Hemangioma of the Left Main Bronchus in an Infant / 대한흉부외과학회지

Capillary hemangioma is the most common vascular tumor in childhood; however, its occurrence in the bronchus is extremely rare. We recently performed a sleeve resection of the left main bronchus on a four-month-old infant with a severe emphysema caused by bronchial capillary hemangioma.

Long Term Results of Bronchial Sleeve Resection for Primary Lung Cancer / 대한흉부외과학회지

BACKGROUND: Bronchial sleeve resection for centrally located primary lung cancer is a lung- parenchyma-sparing operation in patients whose predicted postoperative lung function is expected to diminished markedly. Because of its potential bronchial anastomotic complications, it is considered to be an alternative to pneumonectomy. However, since sleeve lobectomy yielded survival results equal to at least those of pneumonectomy, as well as better functional results, it became and accepted standard procedure for patients with lung cancer who have anatomically suitable tumors, regardless of lung function. In this study, from analyzing of occurrence rate of postoperative complication and survival rate, we wish to investigate the validity of sleeve resection for primary lung cancer. MATERIAL AND METHOD: From January 1989 to December 1998, 45 bronchial sleeve resections were carried out in the Department of Thoracic Surgery of Seoul National University Hospital. We included 40 men and 5 women, whose ages ranged from 23 to 72 years with mean age of 57 years. Histologic type was squamous cell carcinoma in 35 patients, adenocarcinoma in 7, and adenosquamous cell carcinoma in 1 patients. Right upper lobectomy was performed in 24 patients, left upper lobectomy in 11, left lower lobectomy in 3, right lower lobectomy in 1, right middle lobecomy and right lower lobectomy in 3, right upper lobectomy and right middle lobecomy in 2, and left pneumonectomy in 1 patient. Postoperative stage was Ib in 11, IIa in 3, IIb in 16, IIIa in 13, and IIIb in 2 patients. RESULT: Postoperative complications were as follows; atelectasis in 9, persistent air leakage for more than 7 days was in 7 patients, prolonged pleural effusion for more than 2 weeks in 7, pneumonia in 2, chylothorax in 1, and disruption of anastomosis in 1. Hospital mortality was in 3 patients. During follow-up period, bronchial stricture at anastomotic site were found in 7 patients under bronchoscopy. Average follow-up duration of survivals(n=42) was 35.5+/-29 months. All of stage I patients were survived, and 3 year survival rate of stage II and III patients were 63%, 21%, respectively. According to N stage, all of N0 patients were survived and 3 year survival rates of N1 and N2 were 63% and 28% respectively. CONCLUSION: We suggest that this sleeve resection, which is technically demanding, should be considered in patients with centrally located lung cancer, because this lung-saving operation is safer than pneumonectomy and is equally curative.

Surgical Treatments of Complicated Tracheobronchial Stenosis after Insertion of Self Expandable Metallic Stents: 2 Cases Reports / 대한흉부외과학회지

Although most of the patients with endobronchial tuberculosis have some degree of bronchial stenosis, more aggressive treatment is needed to restore the patency of the involved tracheobronchial tree for some patients not responding well to antituberculous chemotherapy combined with steroids. In our first case, we resected stenotic trachea in a 42 years old women who showed overgrowing granulation tissue through the modified Gianturco stent wire which was previously inserted and anastomosed end to end. Another case was a 37 years old male with left main bronchial restenosis complicated after inserting a Strecker stent and sleeve left upper lobectomy was performed.
