Hidatidosis pulmonar: hallazgos y tratamiento quirúrgico en quistes complicados versus no complicados / Pulmonary hydatidosis: findings and surgical treatment in complicated versus uncomplicated cysts

RESUMEN

Resumen Introducción: La hidatidosis humana es una zoonosis prevalente en nuestro medio, causada principalmente por el parásito Echinococcus granulosus. Las complicaciones más frecuentes en el pulmón son la rotura y la infección del quiste. Objetivos: Describir y comparar características clínicas, tratamiento, morbilidad y mortalidad de los pacientes hospitalizados por quiste hidatídico pulmonar (QHP) complicado versus no complicado. Materiales y Método: Estudio analítico longitudinal. Período enero de 1973 - diciembre de 2017 en Hospital Clínico Regional de Concepción "Dr. Guillermo Grant Benavente", Chile. Revisión de base de datos, protocolos de QHP y fichas clínicas. Se utilizó planilla Microsoft Excel® y programa SPSS24®, con función chi cuadrado y t de Student. Se consideró significativo p < 0,05. Resultados: Total 364 episodios de QHP, complicados 179 (49,2%) versus no complicados 185 (50,8%). Edad promedio 36,4 ± 18,9 versus 32,4 ± 19,1 años, hombres 114 (63,7%) versus 107 (57,8%), respectivamente. Se encontró diferencia estadísticamente significativa en sintomatología tos 147 (82,1%) versus 120 (64,9%), hemoptisis 93 (52,0%) versus 45 (24,3%), respectivamente; QHP derecho 115 (64,2%) versus 99 (53,5%), respectivamente; cirugía conservadora 139 (77,7%) versus 167 (90,3%), reoperaciones 22 (12,3%) versus 8 (4,3%), respectivamente; morbilidad 47 (26,3%) versus 30 (16,2%), mortalidad 6 (3,4%) versus 0 (0%), estadía hospitalaria postoperatoria promedio 16,1 ± 14,3 versus 10,7 ± 7,7 días, recidivas 15 (8,4%) versus 13 (7,0%), respectivamente. Discusión: Aproximadamente la mitad de los QHP son complicados. Los QHP complicados presentan diferencias estadísticamente significativas en su clínica, tratamiento, morbilidad, mortalidad y estadía hospitalaria postoperatoria.

ABSTRACT

Background: Human hydatidosis is a prevalent zoonosis in our environment, caused mainly by the Echinococcus granulosus parasite. The most common complications in the lung are cyst rupture and infection. Aim: To describe and compare clinical characteristics, treatment, morbidity and mortality of patients hospitalized for complicated versus uncomplicated hydatid pulmonary cyst (HPC). Materials and Method: Longitudinal analytical study. Period January 1973 - December 2017 at the Regional Clinical Hospital of Concepción "Dr. Guillermo Grant Benavente", Chile. Database, prospective protocols and medical records were reviewed. Microsoft Excel® spreadsheet and SPSS24® program with chi square and Student's t-test were used. It was considered significant p < 0.05. Results: Total 364 episodes of HPC, complicated 179 (49.2%) versus uncomplicated 185 (50.8%). Average age 36.4 ± 18.9 versus 32.4 ± 19.1 years, male 114 (63.7%) versus 107 (57.8%), respectively. A statistically significant difference was found in symptomatology cough 147 (82.1%) versus 120 (64.9%), hemoptysis 93 (52.0%) versus 45 (24.3%), respectively; HPC right 115 (64.2%) versus 99 (53.5%), respectively; resective cyst surgery 139 (77.7%) versus 167 (90.3%), reoperation 22 (12.3%) versus 8 (4.3%), respectively; morbidity 47 (26.3%) versus 30 (16.2%), mortality 6 (3.4%) versus 0 (0%), average postoperative hospital stay 16.1 ± 14.3 versus 10.7 ± 7.7 days, recurrence 15 (8.4%) versus 13 (7.0%), respectively. Conclusions: Approximately half of the HPCs are complicated. Complicated HPCs present statistically significant differences in their clinical, treatment, morbidity, mortality and postoperative hospital stay.
