Surgical treatment of bronchial stricture due to endobronchial tuberculosis: results in 81 consecutive cases / 中华胸心血管外科杂志

ABSTRACT

Objective Severe bronchial stricture due to endobronchial tuberculosis is often accompanied by complex complication,such as obstructiv pneumonia,destroyed lung and bronchiectasis.Its treatment is very diffucult.The present report is to investigate and analyze the indication and efficacy of surgical treatment of bronchial stricture due to severe endobronchial tuberculosis.Methods Reviewed the clinico-pathological records documenting the surgical outcomes in 81 bronchial stricture due to severe endobronchial tuberculosis who underwent lobectomy or pneumonectomy enrolled in our hospital between January 1990 and December 2010.There were 29 male and 52 female.Mean age was(36 ± 12) years (ranged 16-66 years).The three most common reasons of surgery were bronchial stricture accompanied by pulmonary atelectasis,destroyed lung and bronchiectasis(76 cases,93.8％).79 cases had elective operation,whereas one patients required emergency surgery.Pueumonectomy in 51,lobectomy in 16,sleeve resection in 11,segmental resection in 2,and exploratory thoracotomy in 1.If frozen pathological examination showed that endobronchial tuberculosis remained in the bronchial stump,it was covered with muscle flaps,including intercostal muscle flap in 6 cases,latissimus dorsi muscle flap in 5 cases,serratus anterior muscle flap in 5 cases.The mean operative time was 3.2 h (range between 2 h and 5.5 h) and the blood loss averaged 546 ml (range between 100ml and 4 000 ml).The post operative hospital stay averaged(12 ±8)days.Results No intraoperative or early postoperative death occurred.Nine patients developed complications,including BPF in 2,pulmonary infection in 2,empyema in 1,hemorragic shock in 1,hemothorax in 1,incision infection in 1,chylothorax in 1.All 9 cases recovered well after treatment.Pathological examination showed that tuberculosis bronchial remained in the brinchial stump in 13 cases.Neither BPF nor empyema occurred in all the 13 cases.Multivariate analysis revealed that destroyed lung was significant risk factor of postoperative complication.There were 3 late deaths.Five year survival rate was 96.2％.Conclusion Surgical treatment is still the recommeded treatment modatity for bronchial stricture caused by endobronchial tuberculosis due to its excellent results.It should be performed in time when the drug and intraluninal treatment were no effect for avoiding of being progeressed into destroyed lung.
