Objective To investigate the feasibility and therapeutic efficacy of inverted Y-shaped self-expandable metal airway stent for complex airway diseases ( stenosis or fistula) .Methods According to the particular anatomic structure and the pathological changes of complex airway diseases, the inverted Y-shaped self-expandable metal airway stent was designed. 10 stents were implanted in 10 cases of airway complex diseases under the guidance of interventional fibroscopy and fluoroscopy. Results The inverted Y-shaped stents were placed successfully with immediate relief of the symptoms. 100% of the patients were able to be weaned fromoxygen therapy completely. Dyspnea grade improved significantly fromⅢ-Ⅳ to 0-Ⅱ,and oxygen saturation elevated from ( 85 ±5) % in inspiring high concentration oxygen to ( 95 ±3) % in breathing ambient air ( t = - 7. 352, P lt;0. 05) . Breathlessness in 2 cases with tracheoesophageal fistula was relieved after inserting covered airway stent without bucking while foodintaking after fasting 24 hours.Conclusion The placement of inverted Y-shaped self-expandable metal airway stent is a feasible and safetreatment for complex airway disease such as stenosis or fistula.
Conduit failure and conduit airway fistula are rare complications after esophagectomy, however they can be catastrophic resulting in high mortality. Survivors can expect a prolonged hospital course with multiple interventions and an extended period of time prior to being able to resume oral nutrition. High index of suspicion can aid in early diagnosis. Conduit failure usually requires a period of proximal esophageal diversion and staged reconstruction. Conduit airway fistulas may be amenable to endoscopic repair but this has a high failure rate and many patients will require surgical repair with closure of the fistula and interposition of vascularized tissue to minimize recurrence.
ObjectiveTo explore the safety and efficacy of the treatment of peripheral bronchopleural fistula with customized silicone plug through bronchoscope. MethodsA total of 19 patients with BPF admitted to Hunan Provincial People’s Hospital from July 2017 to May 2023 were included. Detailed medical records of the patients were collected, including etiology, fistula location, treatment methods, complications, and effective rates, to assess the safety and efficacy of customized silicone plug occlusion. ResultsThe average age of the 19 patients was 61.58 years (range from 42～84 years). The fistulas were located at the right upper lobe in 8 cases, the right middle lobe in 2 cases, the right lower lobe in 2 cases, the left upper lobe in 2 cases, and the left lower lobe in 5 cases. Causes included 9 cases after pneumonectomy, 6 cases of spontaneous pneumothorax, 1 case post Microwave Ablation Therapy for lung nodule, 1 case of advanced lung cancer under radiotherapy and chemotherapy, 1 case of candidal pneumonia, and 1 case of pulmonary tuberculosis. 15 patients were successfully occluded for the first time, 1 case failed to place the plug, and 3 cases had silicone plug dislodgement within 1 week after the procedure, with a short-term effective rate of 73.68% (14 cases). A total of 40 customized silicone plugs were placed, with an average of (2.10±0.74), and the mean diameter of the plugs used was 6.4 mm, with a range of 3 to 9 mm. Fifteen patients were recruited for long-term follow-up, with a median follow-up time of 15 months (range from 1.5 to 53 months). One patient developed a new fistula on the 45th day, who was treated with a combined small Y-type single bullet-covered stent for occlusion. One patient died of severe pneumonia 3 months postoperatively, and one died of type II respiratory failure at the 30th month, both deaths were unrelated to the interventional procedure. The long-term effective rate was 68.42% (13 cases). ConclusionPlacing customized silicone plugs through bronchoscopy can rapidly and effectively occlude peripheral BPF, with satisfactory long-term outcome.
