    Abstract: Incidences of pilonidal sinus disease are rising. Guidelines rarely consider children and adolescents and evidence for their treatment is rare. The literature is divided on the choice of the preferable surgical procedure. Therefore, we aimed to assess recurrences and complications following different treatment approaches in our multi-centric cohort. Methods We retrospectively assessed all patients treated for pilonidal sinus disease in the paediatric surgical departments of Bonn and Mainz between 01/01/2009 and 31/12/2020. Recurrences were defined according to the German national guidelines. The pre-specified analysis via logistic regression included the operative approach, age, sex, use of methylene blue, and obesity as independent predictors. Results We included 213 patients, of which 13.6% experienced complications and 16% a recurrence. Median time to recurrence was 5.8 months (95% confidence interval: 4.2–10.3), which was slightly higher in children than adolescents (10.3 months, 95% confidence interval: 5.3–16.2 vs. 5.5 months, 95% confidence interval: 3.7–9.7). None of the investigated procedures, excision and primary closure, excision and open wound treatment, pit picking, and flap procedures had a decisive advantage in terms of complications or recurrence. Of the independent predictors, only obesity was associated to complications (adjusted odds ratio: 2.86, 95% confidence interval: 1.05–7.79, P  = 0.04). Conclusions We did not find a difference between the investigated procedures, but our analysis is limited by the small sample size in some subgroups. Our data corroborates that recurrences in paediatric pilonidal sinus disease occur early. Factors linked to these differences remain unknown.

    Abstract: Minimally invasive pectus excavatum repair has gained widespread acceptance and its results and complications are well-described. However, there is a substantial debate on the risks and frequencies of complications following metal bar removal. We, therefore, aimed to analyse all complications that occurred during and after metal bar removal at our two paediatric surgical centres. Methods Bar removal surgeries were identified via procedural codes and electronic records were reviewed using a pre-specified data extraction chart. Both intra- and postoperative complications were included and the latter scored according to Clavien–Dindo. We analysed the influence of the pre-specified potential predictors age, sex, and the number of implanted metal bars on the occurrence of complications using logistic regression. Results We included 279 patients with a median age of 19 years (interquartile range 17–20 years). 15 patients experienced 17 complications. Of 11 postoperative complications, only an enlarging pleural effusion required a chest drain in local anaesthesia, resulting in a Claven-Dindo grade IIIa, whereas the remainder were classified as grade I. Neither age (adjusted odds ratio (aOR) 0.97, 95% confidence interval (CI) 0.84–1.13, P  = 0.73), nor sex (aOR 0.88, 95% CI 0.19–4.07, P  = 0.87) or the number of bars (aOR 0.64, 95% CI 0.15–2.71, P  = 0.547) did influence the occurrence of complications. Conclusion Complications following metal bar removal were scarce in our duocentric retrospective series and usually of minor relevance. However, to address the perceived paucity of data on the frequency and severity of complications following metal bar removal, further studies, including large database research is necessary.

    Abstract: Metal bar removal after the Nuss repair procedure is prone to be cancelled in cases of operating time shortages due it being suitable to be postponed without harming patients. Consequently, planning operation times as exactly as possible could be one solution. Objective Statistical modelling of operation times of metal bar removal after Nuss repair using the prespecified independent predictors of age, sex, intraoperative complications, and number of implanted metal bars. Material and methods We included all patients whose operation notes included an operation time, which was modelled via linear regression and subject to internal validation via bootstrap. Exploratory analyses also consisted of the surgeon’s experience, the number of stabilizers, the body mass index, and preceding re-do surgery for bar dislocation. Results We included 265 patients (14% ♀) with a median age of 19 years (interquartile range 17–20 years), of whom 81% had 1 and 17% had 2 metal bars removed. The prespecified regression model was statistically significant (likelihood ratio 56; df = 5; P   〈  0.001) and had a bias corrected R 2 of 0.148. Patient age influenced operation times by 2.1min per year of life (95% confidence interval 1.3–2.9min; P   〈  0.001) and 16min per explanted metal bar (95% confidence interval: 10–22min; P   〈  0.001). Conclusion The patient-specific factors of age and the number of explanted metal bars influenced the operation times and can be included into scheduling operation times.
