Therapeutic effects of sequential therapy by electric coagulation, cryotherapy and balloon dilation with an electronic video bronchoscope

Abstract

The aim of the current study was to retrospectively analyze clinical data concerning bronchostenosis or bronchial obstruction caused by endobronchial tuberculosis. Fifty-six cases were subjected to bronchoscopy and chest computed tomography to assess the prognosis of bronchostenosis and bronchial obstruction. Based on reliable and effective anti-pulmonary tuberculosis therapy, these conditions were treated sequentially by electric coagulation, cryotherapy and balloon dilation with an electronic video bronchoscope during outpatient consultation or inpatient hospitalization. Fifty-three subjects with bronchostenosis recovered to varying degrees, a recovery rate of 94.6%. Thirteen of the 15 cases with bronchial obstruction reopened (86.7%). The clinical symptoms of these cases appeared to be in remission. Bronchostenosis or bronchial obstruction resulting from endobronchial tuberculosis may be treated by electric coagulation, cryotherapy and balloon dilation with an electronic video bronchoscope.

Efficacy and safety of cryobiopsy versus forceps biopsy for interstitial lung diseases and lung tumours: A systematic review and meta‐analysis

“…Recently, cryotechnology has been utilized for several therapeutic purposes in bronchology including endobronchial cryodebridement procedures for endobronchial tuberculosis, tracheal strictures, endobronchial fibrosis, removal of broncholith, cryosurgery for lung cancer and in immediate debulking of endobronchial tumours (cryorecanalization) . Cryosurgical equipment operates by the Joule–Thomson effect, where a compressed gas released at high flow rapidly expands and creates a very low temperature at the tip of the probe.…”

Utilidad de la crio-tecnología para uso diagnóstico y terapéutico en neumología intervencionista: crio-biopsia pulmonar transbronquial y crioterapia

“…• Muerte: se describe una mortalidad en 30 a 60 días con CBPTB de 0,7 %, mucho menor que la descrita para VATS (1,8%), y en caso de EPID asociada a exacerbación 11,17,26 . Varía en caso de lesiones obstructivas de la vía aérea, con una mortalidad a 30 días de 7,1%, cuyas principales causas fueron hemoptisis y falla respiratoria, relacionando la progresión de la enfermedad tratándose de neoplasia 31 .…”

“…Cuando se comparó la CBPTB con la biopsia transbronquial, los diagnósticos histopatológicos fueron mucho mayores en el grupo de criobiopsia; 74,4% vs 34,1% con una diferencia estadísticamente significativa (p < 0,001), al igual que el rendimiento diagnostico 51,3% vs 29,1% (p = 0,038). El área de las biopsias obtenidas por CBPTB fue mucho mayor 14,7 ± 11 mm 2 que las obtenidas con fórceps 3,3 ± 4,1 mm 2 con diferencia significativa [31][32][33] .…”

“…La crioterapia tiene varias indicaciones con propósitos terapéuticos e incluyen toma de muestras de tumores endobronquiales, crio-desbridamiento en casos de tuberculosis endobronquial, manejo de estenosis traqueales y fibrosis endobronquial, remoción de cuerpos extraños y coágulos, criocirugía de cáncer de pulmón y crio-recanalización inmediata con resección completa de tumores endobronquiales 31,38 .…”

Feasibility and Safety of Pleuroscopic Cryobiopsy of the Pleura: A Prospective Study

“…Biopsy via cryoprobe, rst used in 1968, has mainly been employed in the management of obstructive endobronchial tumors. Recently, cryotherapy in bronchoscopy has been used for several purposes including management of endobronchial tuberculosis [10], endobronchial tumors [11][12][13], for diagnosis of interstitial lung disease (ILD) [14][15][16][17], and peripheral lung lesion [18]. ese studies have demonstrated that the cryoprobe is feasible and a more e cient diagnostic tool with a superior diagnostic rate and ability to obtain a larger specimen with better preserved cellular architecture than forceps biopsy.…”
