Purpose Lung-sparing strategies such as segmentectomy or atypical resection have been advocated for small congenital pulmonary airway malformation (CPAM), even by thoracoscopy. The aims of our study were to evaluate surgical and clinical outcome of patients undergoing lung-sparing surgery and to determine whether thoracoscopy is superior to thoracotomy. Methods We conducted a retrospective review of patients who underwent lung-sparing resection for CPAM from 2004 to 2018. Demographic data, presenting symptoms, size and location of the CPAM, operative and post-operative data were collected and analyzed according to surgical technique (thoracoscopy-TS, vs thoracotomy-TO). Data were compared using Fisher's exact test for qualitative values and Mann-Whitney test for quantitative values. P values less than 0.05 were considered as statistically significant. Results 167 lung-sparing surgery procedures were performed (segmentectomy n = 21 or atypical resection n = 146). 67 procedures were completed in TS. All histological examination revealed negative margins for residual CPAM. Patients in the TS group were older and presented a higher weight compared to the TO group. TS was associated with shorter duration of pleural drainage and shorter hospital stay. Rate of conversion was 35% (n = 29). Location of CPAM in the lower lobe and CPAM size greater than 5 cm were predictor factors of conversion from TS to TO. Conclusion Lung-sparing surgery for CPAM is a safe and feasible technique in pediatric patients. TS results in reduced postoperative morbidity compared to TO and should be proposed as first surgical approach for selected patients.

Aim of the study: To assess the efficacy of a novel technique (echo-assisted intersphincteric autologous microfragmented adipose tissue injection, also called “anal-lipofilling”) in the management of non-responsive fecal incontinence in children born with anorectal malformations (ARMs). Methods: Following ethical committee approval (CHPED-MAR-18-02), anal-lipofilling was proposed to patients with fecal incontinence not responsive to medications or bowel management (bowel enema and/or transanal irrigation automatic systems), then a prospective study was conducted. Anal-lipofilling consisted of three phases: lipoaspiration from the abdominal wall, processing of the lipoaspirate with a Lipogems system and intersphincteric injection of the processed fat tissue via endosonographic assistance. A questionnaire based on Krickenbeck’s scale (KS) was administered to the patients to evaluate the clinical outcome. Main Results: Four male patients (three recto-urethral fistula, and one recto-perineal fistula) underwent the anal-lipofilling procedure at a mean age of 13.0 ± 4.2 yrs. There were no complications during or after the procedure. From an initial assessment of the patients there was an improvement in the bowel function at a median follow up of 6 months, with better scores at KS (100% Soiling grade three pre-treatment vs. 75% grade one post-treatment). Conclusions: Even if our Study is preliminary, echo-assisted anal-lipofilling could be considered as a feasible and safe alternative technique in the management of the fecal incontinence in non-responding ARMs patients. More studies are still necessary to support the validity of the implant of autologous adipose tissue in the anal sphincter as a therapy for fecal incontinence in children born with ARMs.

Background: The diagnosis of acute appendicitis (AA) remains challenging, especially in pediatrics, because early symptoms are not specific, and the younger the patient the more difficult their interpretation is. There is a large degree of agreement between pediatric surgeons on the importance of an early diagnosis to avoid complicated acute appendicitis (CAA) and its consequences. The aim of this study is to assess if Interleukin 6 (IL-6) could enhance the sensitivity (Sn) and specificity (Sp) of the currently available and routinely performed diagnostic tools in case of suspected AA in pediatric patients. Materials and Methods: A prospective observational study was conducted including patients who underwent appendectomy between November 2020 and March 2022. We divided patients into three groups: not inflamed appendix (group NA), not complicated AA (group NCAA), and complicated AA (group CAA). We compared the mean values of white blood cells (WBC), neutrophils, fibrinogen, ferritin, aPTT, INR, C-reactive protein (CRP), IL-6, and CRP between the three groups. Then we evaluated Sn, Sp, and odds ratio (OR) of IL-6 and CRP alone and combined. Results: We enrolled 107 patients operated on for AA (22 in Group NA, 63 in Group NCAA, and 21 in group CAA). CRP levels resulted in a significant increase when comparing CAA with NA (p = 0.01) and CAA with NCAA (p = 0.01), whereas no significance was found between NA and NCAA (p = 0.38). A statistically significant increase in average IL-6 levels was found when comparing NCAA with NA (p = 0.04), CAA with NA (p = 0.04), and CAA with NCAA (p = 0.02). Considering CRP alone, its Sn, Sp, and OR in distinguishing NA from AA (both NCAA and CAA together) are 86%, 35%, and 33,17, respectively. Similarly, Sn, Sp, and OR of IL-6 alone are 82%, 54%, and 56, respectively. Combining CRP and IL-6 serum levels together, the Sn increases drastically to 100% with an Sp of 40% and OR of 77. Conclusions: Our study may suggest an important role of IL-6 in the detection of AA in its early stage, especially when coupled with CRP.
