Objectives

While the short-term results of lung volume reduction surgery are known, follow-up over several years has not often been described. The purpose of the present study was to describe results in terms of functional improvement, dyspnea, quality of life, and mortality over a 4-year period in patients with advanced emphysema.

Patients and methods

Fourteen successive patients were enrolled between 1996 and 2000 and studied prospectively for 4 years. All patients served as their own controls and initially received pulmonary rehabilitation and medication. Preoperative data were used as baseline and were compared to postoperative data over 4 years. The data analyzed were: functional improvement (forced expiratory volume in 1 second [FEV1]), quality of life, dyspnea, and patient loss due to death or referral to a lung transplantation program.

Results

Patients with advanced emphysema (mean FEV1 [SD]: 22.8% [11%] of predicted) were studied. Postoperative mortality was 14%. Overall mortality (postoperative plus deaths due to respiratory insufficiency) was 28% at 1 year and 35% at 4 years. Two patients died of cancer and 5 were referred for transplantation. At 3 months, FEV1 had improved more than 15% in 9 patients (64%); the improvement was maintained in 43% of patients at 1 year and 7% at 4 years. Improvement in dyspnea paralleled improvement in FEV1. Overall, at 3 months mean FEV1 had improved 41.9% (68%), transitional dyspnea index 2.7 (3), and quality of life questionnaire score 1 (0.9). Thus, improvements were considerable, but there was great variation. Preoperative mean decrease in FEV1 was 50 (32) mL/y, and postoperative decrease 194 (70) mL/y.

Conclusions

With the inclusion criteria used, there was considerable variation in the results. Significant overall functional improvement was maintained in 50% of the patients 1 year following surgery and in 7% 4 years after surgery. Given such results, together with a surgical mortality rate of 14% and overall mortality of 28% in the first year, we believe that the criteria for using lung reduction surgery should be revised.

Objetivos

Aunque se conocen los resultados de la cirugía de reducción de volumen a corto plazo, son pocas las series que describen el seguimiento durante varios años. El propósito de este estudio es describir los resultados, en relación con la mejoría funcional, disnea, calidad de vida y mortalidad, a lo largo de 4 años en pacientes con enfisema avanzado.

Pacientes Y Métodos

Se ha estudiado de forma prospectiva a 14 pacientes incluidos sucesivamente entre los años 1996 y 2000, y seguidos a lo largo de 4 años. Cada paciente fue su propio control y recibió inicialmente tratamiento rehabilitador y farmacológico. Se utilizaron los datos preoperatorios como basales y se compararon con los postoperatorios a lo largo de 4 años. Los datos analizados fueron: mejoría mecánica —volumen espiratorio forzado en el primer segundo (FEV1)—, calidad de vida, disnea y pérdida del paciente, tanto por fallecimiento como por remitirlo a un programa de trasplante pulmonar.

Resultados

Se incluyó a pacientes con enfisema avanzado (FEV1: 22,8 ± 11%). La mortalidad postoperatoria fue del 14% y, unida a la originada por la insuficiencia respiratoria, del 28 y el 35% al año y a los 4 años, respectivamente. Dos pacientes murieron por cáncer y 5 se remitieron a trasplante. A los 3 meses, 9 pacientes (64%) habían mejorado más del 15% el FEV1 y esta mejoría se mantuvo en el 43% al año y en el 7% a los 4 años. La mejoría de la disnea fue paralela a la mejoría del FEV1. Globalmente, a los 3 meses el FEV1 había mejorado un 41,9 ± 68%, el índice transicional de disnea un 2,7 ± 3 y la calidad de vida 1 ± 0,9, es decir, mejorías importantes pero con mucha dispersión. La caída del FEV1 prequirúrgica fue de 50 ± 32 ml/año, y la posquirúrgica de 194 ± 70 ml/año.

Conclusiones

Con los criterios de inclusión seguidos, hay una importante variabilidad en los resultados y, globalmente, se mantiene una mejoría funcional significativa en el 50% de los pacientes al año de la cirugía y del 7% a los 4 años. Estos hechos, unidos a una mortalidad operatoria del 14% y global del 28% en el primer año, hacen que se tengan que revisar los criterios de indicación de esta cirugía.
