“…Moreover, personalized treatment is urgently needed to find suitable candidates, improve treatment compliance, and improve outcomes. In previous studies, a simple change in the use time, pressure, or frequency of VB during the treatment period in all patients may not address the conflict between compliance and the treatment protocol ( 14 , 15 , 21 , 22 ). Although prolonged usage time may be associated with better outcome, it may result in poor treatment compliance and the discontinuation of VB therapy.…”

ObjectiveThe outcome of vacuum bell (VB) treatment for preschool patients with pectus excavatum (PE) is poorly understood. We aim to investigate the short-term treatment effect of VB with a three-dimensional scanner and assess the clinical and demographic factors that might influence treatment outcomes.MethodsWe conducted a chart review study to review the records of preschool patients with PE who received VB treatment in a tertiary hospital from January 1, 2021, through January 1, 2022. Demographic data and chest wall deformity assessments were recorded at follow-up, including the anterior chest wall depths and depth ratio (DR). The demographic and clinical factors influencing treatment outcomes were tested using a logistic regression model.Results139 patients who accepted vacuum bell treatment were included in the final study analysis, with a mean age of 4.6 years and a BMI of 14.9. Forty-three patients (30.9%) with a depth of less than 3 mm met the termination criteria and showed cosmetic results. The changes in depths (P < 0.001) and DR (P < 0.001) were statistically significant in 55 patients with three or four follow-ups. Multifactor logistic regression analysis showed that initial depth (OR 0.69, 95% CI 0.58–0.84, P < 0.001) and treatment period (OR 1.58, 95% CI 1.23–2.04, P < 0.001) were independent predictors of achieving complete correction.ConclusionVB is an effective treatment modality in preschool patients in the short-term follow-up, which is influenced by the depth of depression and the duration of treatment. However, further prospective studies are needed to confirm these results.

“…It has been observed that pressures above 300 mbar cause pain and do not provide better results (5,9) . Vacuum pressure measurement devices coupled to the bell have been recently developed, allowing pressure to be increased in a gradual and controlled fashion (10,11) .…”

“…A treatment initiation protocol has been recently published, with a gradual increase in time and pressure, which is controlled with a measuring device coupled to the VB -a vacuum gauge. This protocol lasts for 6 months and seemingly reduces complications, improves tolerance, and increases treatment adhesion (10) . Our initiation protocol is similar to that used by most authors.…”

Objective. To assess the efficacy of the vacuum bell during puberty, according to the daily hours of use and treatment duration.Materials and methods. A retrospective analysis of patients treated with vacuum bell during puberty in the 2010-2021 period was carried out. Several variables were collected, including baseline and final sinking, repaired sinking expressed in cm and as a percentage from baseline sinking, daily hours of use, treatment duration, and complications. Patients were categorized into groups according to the daily hours of use (≤ 3 hours; 4-5 hours; ≥ 6 hours) and treatment duration (6-12 months; 13-24 months; 25-36 months; > 36 months), and they were statistically analyzed.Results. A total of 50 patients -41 male and 9 female-were studied, with a mean age of 12.5 years (range: 10-14 years). No significant differences among groups were observed in terms of baseline sinking, thoracic index, and final sinking. Repaired sinking did increase with the daily hours of use, with significant differences. Complications were mild. 3 patients withdrew from follow-up, and 5 out of the 25 patients who completed treatment achieved a good repair.Conclusions. To increase treatment efficacy, the vacuum bell should be used for 6 hours/day during puberty. This method is well-tolerated, causes mild complications, and may be an alternative to surgery in some cases.

“…Recientemente se ha publicado un protocolo de inicio de tratamiento con incremento gradual de tiempo y presión, que es controlada con un medidor acoplado a la CS denominado vacuómetro. Este protocolo tiene una duración de 6 meses y parece reducir las complicaciones, mejorar la tolerancia y aumentar la adherencia al tratamiento (10) . Nuestro protocolo de inicio es similar al utilizado por la mayoría de los autores.…”

pubertad, según las horas diarias de uso y la duración del tratamiento. Material y métodos. Se evaluaron retrospectivamente los pacientes tratados con campana de succión durante la pubertad en el periodo 2010-2021. Se recogieron diferentes variables, incluyendo el hundimiento inicial y final, el hundimiento corregido expresado en centímetros y en porcentaje con respecto al hundimiento inicial, las horas diarias de uso, la duración del tratamiento y las complicaciones. Se categorizaron los pacientes en grupos según las horas diarias de uso (≤ 3 horas; 4-5 horas; ≥ 6 horas) y la duración del tratamiento (6-12 meses; 13-24 meses; 25-36 meses; > 36 meses), y se analizaron estadísticamente.Resultados. Se estudiaron un total de 50 pacientes; 41 varones y 9 mujeres, con una edad media de 12,5 años (rango 10-14 años). No se observaron diferencias significativas entre los diferentes grupos en relación con el hundimiento inicial, el índice torácico y el hundimiento final. El hundimiento corregido aumentó en relación con las horas diarias de uso, con diferencias significativas. Las complicaciones fueron leves, 3 pacientes abandonaron el seguimiento y 5 pacientes de los 25 que finalizaron el tratamiento, alcanzaron una buena corrección.Conclusiones. Para aumentar la eficacia del tratamiento, el tiempo de uso de la campana de succión durante la pubertad debería alcanzar las 6 horas diarias. Este método es bien tolerado, presenta leves complicaciones y puede ser una alternativa a la cirugía en algunos casos.
