Right uniportal video-assisted thoracoscopic surgery lung-sparing sleeve resection of the bronchus intermedius

Complete surgical resection has been the main treatment modality for pulmonary neoplasms without locoregional or distant spread of the disease. Sleeve resections were developed to minimize unnecessary loss of pulmonary parenchyma mainly in the case of centrally located tumours. Experience with sleeve resections and recent technological advancements made minimally invasive resection possible for selected patients. We present a case report of the totally thoracoscopic uniportal sleeve resection of the bronchus intermedius without any resection of pulmonary parenchyma. The operation was performed successfully, and the patient did not experience any postoperative complications. In this case report, we describe our surgical approach and short-term results.

[Successful Closure of Postpneumonectomy Bronchopleural Fistula with Inserting Technique of Omental Pedicle Flap into the Right Main Bronchus:Report of a Case].

A 67-year-old male was admitted to our hospital for the treatment of pyothorax due to bronchopleural fistula at right main bronchus after pneumonectomy for lung cancer( squamous cell carcinoma, pathological stageⅢB). After tube drainage and fenestration, we performed operation to close large diameter fistula, that was almost fully opened stump of the right main bronchus. Omental flap was sutured roughly to the fistula with four stiches and inserted into the bronchus lumen, and covered with latissimus dorsi muscle flap to fix omental pedicle flap and additionally performed thoracoplasty to close the residual space of the pleural cavity. Fistula at the stump became airtight after operation and pyothorax was cured, so our method was thought to be available to close large diameter bronchopleural fistula with omental pedicle flap.

[Cervicothoracotomy for right upper sleeve lobectomy with carinal resection in the treatment of central lung cancer]. / Kombinirovannyi tserviko-torakotomnyi dostup dlya vypolneniya verkhnei lobektomii sprava s rezektsiei bifurkatsii trakhei pri tsentral'nom rake legkogo.

We demonstrated successful treatment of patients with complicated central lung cancer, who underwent right upper sleeve lobectomy with carinal resection. We have used the following options for carinal reconstruction: anastomosis of trachea with the left main bronchus and anastomosis of intermediate bronchus with the left main bronchus (clinical case No. 1) or with trachea (clinical case No. 2). Cervicothoracotomy provided correct N-staging and mobilization of trachea with left main bronchus. This approach provided compliance with oncological principles of surgical treatment of lung cancer and significantly reduced tension of anastomosis. These aspects are important for satisfactory immediate functional and oncological results after right upper sleeve lobectomy with carinal resection.

Complete transection of the bilateral main bronchus in a 5-year-old patient: a case report.

BACKGROUND: Tracheobronchial injuries caused by blunt chest trauma are rare in children, and such injuries usually involve multiple organs. Most cases involve respiratory failure on the way to the hospital, and the mortality rate is high. Herein, we describe the case of a 5-year-old patient who fell from an electric vehicle, causing complete rupture of the bilateral main bronchus. CASE PRESENTATION: We treated a 5-year-old patient with complete bilateral main bronchus rupture. Chest computed tomography (CT) failed to detect bronchial rupture. Continuous closed thoracic drainage resulted in a large amount of bubble overflow. Tracheal rupture was suspected. Fibreoptic bronchoscopy revealed complete rupture of the right main bronchus and rupture of the left main bronchus. Emergency tracheoplasty was performed under cardiopulmonary bypass (CPB). During the operation, we found that the bilateral main bronchi were completely ruptured. Postoperative recovery was smooth. The traditional surgical method for treating these injuries is lateral thoracotomy. However, a median sternotomy provides a better opportunity for selective repair. Extracorporeal circulation-assisted surgery is required for patients with unstable breathing. CONCLUSION: Complete fractures of the bilateral main bronchi are rare. Bronchial rupture should be suspected in the presence of expansion defect-dropped lungs and massive air leakage despite tube thoracostomy in haemopneumothorax developing after thoracic trauma. Extracorporeal circulation-assisted tracheoplasty is a relatively safe option for children whose respiratory system is difficult to maintain, thus ensuring oxygenation ventilation and a clear surgical field.

[Comparative analysis of the effects of bronchial intubation and bronchial blocker on the outcomes of thoracoscopic surgery in infants and small children].

Objective: To compare the effects of bronchial intubation and blocker on the outcomes of thoracoscopic surgery in infants and small children. Methods: A total of 387 children, including 210 males and 177 females, aged (17.5±8.3) months, who underwent elective thoracoscopic surgery under general anesthesia in Children's Hospital Affiliated to Capital Institute of Pediatrics from January 2019 to August 2023 were retrospectively analyzed. The children were divided into bronchial intubation group and bronchial blocker group according to the intraoperative single-lung ventilation mode. After matching the age factor using the propensity score matching with nearest neighbor matching method, 258 cases were finally included in the bronchial intubation group, and 129 cases were included in the bronchial blocker group. The primary outcome was the incidence of postoperative pulmonary complications in two groups. The secondary outcomes included the incidence of intraoperative hypoxemia, postoperative oxygenation index, postoperative extubation time, the length of postoperative hospitalization and the total medical expenses during hospitalization between the two groups. Results: The incidence of postoperative pulmonary complications in the bronchial intubation group and bronchial blocker group was 15.5% (40/258) and 12.4% (16/129), the incidence of intraoperative hypoxemia was 20.2% (52/258) and 16.3% (21/129), the postoperative oxygen indexes were 306 (269, 323) and 311 (274, 336) mmHg (1 mmHg=0.133 kPa), the extubation time was (9.2±4.5) and (8.9±4.2) min, the length of postoperative hospitalization was (5.5±0.6) and (5.5±0.5) days and the total medical expenses were (34±6) and (35±6) thousand yuan, with no statistically significant differences between the two groups (all P>0.05). Conclusion: Both bronchial intubation and blocker can be used for one lung ventilation in thoracoscopic surgery for infants and small children, without affecting the postoperative outcomes.

Slide tracheoplasty for congenital tracheal stenosis with involvement of the carina and bronchi: a case report.

A female newborn presented with respiratory distress at birth and was diagnosed with congenital tracheal stenosis. The stenosis was positioned at the distal trachea and compromised the carina and the right and left bronchi. She underwent surgical treatment using circulatory life support with veno-arterial peripheral extracorporeal membrane oxygenation, and the airway was reconstructed using the slide tracheoplasty technique to build a neocarina. The patient had an excellent postoperative course, was successfully weaned from extracorporeal membrane oxygenation and invasive ventilation, and was discharged.

Right Lower Sleeve Lobectomy: Detailed Technique and Perioperative Patient Management.

PURPOSE: This report reviews our experience with right lower sleeve lobectomy and describes our technique and approach to perioperative patient management. METHODS: We retrospectively reviewed 11 patients who underwent right lower sleeve lobectomy for lung cancer. Surgical techniques and perioperative management were also investigated. RESULTS: Bronchoplasty was performed using 4-0 absorbable monofilament sutures. The deepest portion was anastomosed using continuous sutures; interrupted sutures were used for the more superficial portions. The truncus intermedius and right middle lobe bronchus should be anastomosed in a natural position. Anastomosis patency was confirmed using intraoperative bronchoscopy. Separation of the right upper and middle lobes and pericardiotomy at the inferior edge of the superior pulmonary vein are useful for mobilizing the right middle lobe. Death during hospitalization and treatment-related death did not occur. One patient developed pneumonia, and another developed a bronchopleural fistula. CONCLUSION: We reported our technique of right lower sleeve lobectomy and our approach to perioperative patient management. Sharing knowledge is essential to completing this rare surgery.

Protecting the non-operative lobe/s of the operative lung can reduce the pneumonia incidence after thoracoscopic lobectomy: a randomised controlled trial.

Lung isolation usually refers to the isolation of the operative from the non-operative lung without isolating the non-operative lobe(s) of the operative lung. We aimed to evaluate whether protecting the non-operative lobe of the operative lung using a double-bronchial blocker (DBB) with continuous positive airway pressure (CPAP) could reduce the incidence of postoperative pneumonia. Eighty patients were randomly divided into two groups (n = 40 each): the DBB with CPAP (Group DBB) and routine bronchial blocker (Group BB) groups. In Group DBB, a 7-Fr BB was placed in the middle bronchus of the right lung for right lung surgery and in the inferior lobar bronchus of the left lung for left lung surgery. Further, a 9-Fr BB was placed in the main bronchus of the operative lung. In Group BB, routine BB placement was performed on the main bronchus on the surgical side. The primary endpoint was the postoperative pneumonia incidence. Compared with Group BB, Group DBB had a significantly lower postoperative pneumonia incidence in the operative (27.5% vs 5%, P = 0.013) and non-operative lung (40% vs 15%) on postoperative day 1. Compared with routine BB use for thoracoscopic lobectomy, using the DBB technique to isolate the operative lobe from the non-operative lobe(s) of the operative lung and providing CPAP to the non-operative lobe(s) through a BB can reduce the incidence of postoperative pneumonia in the operative and non-operative lungs.

[Management of Tracheobronchial Injuries due to Brunt Trauma].

BACKGROUND: Tracheobronchial injuries resulting from blunt trauma are relatively rare among chest injuries. However, if these injuries are not managed properly, they can be fatal. The prognosis is intricately linked to the precise diagnosis and treatment. We herein report three cases of tracheobronchial trauma that required surgical intervention. Case 1:A 17-year-old male sustained injuries when his torso became entangled in heavy machinery. The diagnosis revealed a tear in the right main bronchus, which required transportation with left single- lung ventilation. The patient was treated by tracheobronchial reconstruction. Case 2:A 71-year-old male experienced trauma when his car collided with a utility pole. He was transported to the hospital after tracheal intubation due to a laceration of the tracheal membranous area. The site of the injury was closed with sutures. Case 3:A 17-year-old female who had been struck by a train suffered acute respiratory failure and was transported to the hospital after intubation. Veno-venous extracorporeal membrane oxgenation (VV-ECMO) was initiated in response to poor oxygenation. Complete rupture of the right middle bronchial trunk and laceration of the right main bronchial membrane were observed, and bronchoplasty was performed. CONCLUSION: A swift and accurate diagnosis, coupled with timely and judicious therapeutic interventions, play a pivotal role in managing tracheal and bronchial injuries.

[Complete Disruption of the Left Main Bronchus Treated with Extracorporeal Membrane Oxygenation Support and Pneumonectomy].

A 60-year old woman, sandwiched between two boats was brought to our hospital with severe respiratory failure. She was in pre-shock and there was extensive cutaneous emphysema from the face to abdomen. She required respirator support and bilateral chest tubes for hemopneumothorax. On the patient's 3rd hospital day, she received venovenous extracorporeal membrance oxgenation( ECMO) due to sudden ventilatory failure. The bronchofiberscopy revealed complete disruption of the left main bronchus and occlusion of the right one owing to blood clot and sputum. Because of significant destruction of the left main bronchus, we didn't attempt bronchoplasty, and performed left pneumonectomy under veno-venous (VV)-ECMO. The postoperative course was uneventful, and she was discharged after 30 days with satisfactory outcome.

Left Upper Division Segmentectomy Compared with Lobectomy for Lung Expansion and Bronchus Tortuosity.

BACKGROUND: For patients with left upper lobe lesions, the functional benefit of left upper division segmentectomy over left upper lobectomy remains controversial. This study evaluated the clinical and functional outcomes after these two procedures. METHODS: This retrospective study included 135 patients with left upper lobe lesions (left upper lobectomy, 110; left upper division segmentectomy, 25). Propensity score matching was used to compare the two groups. Spirometry and computed tomography volume assessments were performed to evaluate bronchus angle and tortuosity. Short-term clinical respiratory symptoms were assessed via medical record reviews. RESULTS: Patients in both groups had similar preoperative characteristics, apart from tumor size (left upper division segmentectomy, 1.6 ± 0.9 cm; left upper lobectomy, 2.8 ± 1.7 cm; p = 0.002). After propensity score matching, both groups had similar preoperative spirometry and pathological results. The postoperative spirometry results were similar; however, the left upper division segmentectomy group had a significantly smaller decrease in left-side computed tomography lung volume compared with that in the left upper lobectomy group (left upper division segmentectomy, 323.6 ± 521.4 mL; left upper lobectomy, 690.7 ± 332.8 mL; p = 0.004). The left main bronchus-curvature index was higher in the left upper lobectomy group (left upper division segmentectomy, 1.074 ± 0.035; left upper lobectomy, 1.097 ± 0.036; p = 0.013), and more patients had persistent cough in the left upper lobectomy group (p = 0.001). CONCLUSIONS: Left upper division segmentectomy may be a promising option for preventing marked bronchial angulation and decreasing postoperative persistent cough in patients with left upper lobe lung cancer.

[Resected Right Upper Lobe Lung Cancer with Displaced Bronchus and Anomalous Pulmonary Vein].

The patient is a 77-year-old man. He was referred to our hospital after a chest computed tomography (CT) scan revealed a 6.5 cm-sized mass in the right lung apex. Bronchoscopy revealed adenocarcinoma, clinical stageⅡB, and the patient was referred for surgery. Preoperative 3D-CT revealed the presence of a displaced bronchus, probably B1a, branching from the right main bronchus centrally from the upper lobe bronchus, and an abnormal vessel (V2) running dorsal to the upper lobe bronchus and the right main bronchus, and returning directly to the left atrium. Surgery was performed by resectioning the right upper lobe through a posterolateral incision, combined resection of the wall pleura, and lymph node dissection (ND2a-2). Because lung cancer surgery is sometimes accompanied by abnormal bronchial and pulmonary vascular branches, it is essential to thoroughly examine the patient before surgery for checking abnormal branches by bronchoscopy and 3D-CT.

Airway smooth muscle and long-term clinical efficacy following bronchial thermoplasty in severe asthma.

The mechanism of action of bronchial thermoplasty (BT) treatment for patients with severe asthma is incompletely understood. This study investigated the 2.5-year impact of BT on airway smooth muscle (ASM) mass and clinical parameters by paired data analysis in 22 patients. Our findings demonstrate the persistence of ASM mass reduction of >50% after 2.5 years. Furthermore, sustained improvement in asthma control, quality of life and exacerbation rates was found, which is in line with previous reports. An association was found between the remaining ASM and both the exacerbation rate (r=0.61, p=0.04 for desmin, r=0.85, p<0.01 for alpha smooth muscle actin (SMA)) and post-bronchodilator forced expiratory volume in 1 s predicted percentage (r=-0.69, p=0.03 for desmin, r=-0.58, p=0.08 for alpha SMA). This study provides new insight into the long-term impact of BT.
