The use of diaphragmatic flap for the main bronchus stump reinforcement in right-sided pneumonectomy performed for destructive pulmonary tuberculosis with drug resistance of <i>Mycobacterium tuberculosis</i>

INTRODUCTION. Drug-resistant tuberculosis with subtotal and total lesion of one of the lungs is the most common indication for pneumonectomy. This operation is accompanied by a high risk of postoperative complications, among which the most dangerous is pleural empyema with bronchopleural fistula. In this regard, the prevention of this complication is an extremely important task.The OBJECTIVE was to study the results of using a diaphragmatic flap to prevent the development of right main bronchus stump insufficiency with bronchopleural fistula in patients with destructive pulmonary tuberculosis. METHODS AND MATERIALS. A retrospective study was carried out for the period from 2015 to 2019. The study included 13 patients who underwent right-sided pneumonectomy with diaphragmoplasty of the right main bronchus stump. Indications for diaphragmoplasty were: persistent bacterial excretion at the time of surgery, pre-existing bronchopleural fistula, intraoperative pleural contamination, progressive course of a specific process.RESULTS. The postoperative period was smooth in 10 (77 %) patients. Postoperative complications developed in 3 (23 %) patients: in 1 (7.7 %) case, there was right main bronchus stump insufficiency with bronchopleural fistula and in 2 (15.3 %) cases, there were right main bronchus stump insufficiency without bronchopleural fistula. A satisfactory immediate result was achieved in 12 (92.3 %) patients.CONCLUSION. The diaphragmatic flap is a reliable material for plasty of the right main bronchus stump in order to prevent the formation of bronchopleural fistula in destructive pulmonary tuberculosis.

[Treatment of patients with rare bronchial foreign body - spruce branch]

Spruce branch is a rare radiolucent bronchial foreign body. Despite modern imaging tests and endoscopic examination, this foreign body is often detected only intraoperatively. This study enrolled 4 patients with spruce branch aspiration. In the 4^th case, spruce branch was removed during rigid bronchoscopy that was associated with «lodging» type of foreign body. In two cases, spruce branch migrated to peripheral bronchial segments («extrusive» type) that required surgical treatment (thoracoscopy with resection of the right basal pyramid segments and wedge resection of the right lower lobe). The 3^rd case was the most interesting. Initially, the foreign body was «underlying», but it migrated after partial endoscopic removal that finally required right-sided lower lobectomy. This report describes the peculiarities of clinical course and management of patients with a rare type of radiolucent bronchial foreign body - spruce branch.

Surgical treatment of spondylitis and diaphragm relaxation in patient less than 1 year old

DESIGN

Case report.

INTRODUCTION

The combination of severe post-infectious kyphosis and diaphragm relaxation is extremely rare in patient early than 1 year old. Its no publications concerning their simultaneous surgical treatment.

CASE DESCRIPTION

7-Month-old girl had simultaneous spinal reconstruction with anterior and posterior instrumentation and plastic of diaphragm because of sequelae of non-granulenatous spondylitis complicated by severe kyphosis (54°) and diaphragm relaxation. Between 1.5 and 3 months of live she had several infections incl. pneumonia, enterocolitis, ENT infection. Anterior fusion was done by titanium mesh with auto-rib, posterior - by compressive rods based on low-profile hooks. The deformity was reduced till 20°. 2.5 years after initial surgery and 1 year after removal of posterior instrumentation the adequate level of diaphragm and minimal (4°) loss of kyphosis correction were identified.

CONCLUSIONS

The combination of spondylitis and diaphragm relaxation in early aged patient could be explained but it could not be confirmed as a sequelae of late-onset neonatal sepsis with a multi-focal lesions. The simultaneous surgery provided on the combined approaches (trans-thoracic and posterior) looks as optimal options in such combination of pathologies. In remains controversial how will the spine develop after so early reconstructive surgery, including in situ stable anterior fusion carried out by titanium mesh with auto-rib.
