ABSTRACT
INTRODUCTION: Surgery plays a key role in the management of Neuroblastic tumours (NB), where the standard approach is open surgery, while minimally invasive surgery (MIS) may be considered an option in selected cases. The indication(s) and morbidity of MIS remain undetermined due to small number of reported studies. The aim of this study was to critically address the contemporary indications, morbidity and overall survival (OS) and propose guidelines exploring the utility of MIS for NB. MATERIALS & METHODS: A SIOPEN study where data of patients with NB who underwent MIS between 2005 and 2018, including demographics, tumour features, imaging, complications, follow up and survival, were extracted and then analysed. RESULTS: A total of 222 patients from 16 centres were identified. The majority were adrenal gland origin (54%) compared to abdominal non-adrenal and pelvic (16%) and thoracic (30%). Complete and near complete macroscopic resection (>95%) was achieved in 95%, with 10% of cases having conversion to open surgery. Complications were reported in 10% within 30 days of surgery. The presence of IDRF (30%) and/or tumour volume >75 ml were risk factors for conversion and complications in multivariate analysis. Overall mortality was 8.5%. CONCLUSIONS: MIS for NB showed that it is a secure approach allowing more than 95% resection. The presence of IDRFs was not an absolute contraindication for MIS. Conversion to open surgery and overall complication rates were low, however they become significant if tumour volume >75 mL. Based on these data, we propose new MIS guidelines for neuroblastic tumours.

OBJECTIVE: The accuracy of prenatal ultrasound examination in detecting jejunal and ileal atresia has been reported in the literature to be highly variable, at 25-90%. The aim of this systematic review was to evaluate the accuracy of prenatal ultrasound in detecting non-duodenal small bowel atresia (ND-SBA). METHODS: MEDLINE, EMBASE and The Cochrane Library, including The Cochrane Database of Systematic Reviews (CDSR), Database of Abstracts of Reviews of Effects (DARE) and The Cochrane Central Register of Controlled Trials (CENTRAL), were searched electronically. The overall detection rate of jejunal or ileal atresia using ultrasound was reported. The accuracy of using polyhydramnios and dilated loops of bowel as diagnostic signs was also explored. RESULTS: Sixteen studies involving 640 fetuses were included in this review. The detection rate of ND-SBA by prenatal ultrasound was highly variable, with values ranging from 10 to 100%, with an overall prediction of 50.6% (95% CI, 38.0-63.2%). When analyzed separately, the detection rates of jejunal and ileal atresia were 66.3%, (95% CI, 33.9-91.8%) and 25.9% (95% CI, 4.0-58.0%), respectively. Both dilated loops of bowel and polyhydramnios as diagnostic signs for ND-SBA provided a low overall detection rate. CONCLUSIONS: The diagnostic performance of prenatal ultrasound in identifying ND-SBA is extremely variable. Large studies are needed in order to identify objective and combined criteria for the diagnosis of these anomalies.

Five children with a neuroendocrine tumour (NET) of the appendix associated with a parasitic bowel infection are described, and the possibility of inflammation-triggered carcinogenesis is discussed. Schistosoma haematobium is linked primarily to bladder cancer but it has been reported in association with several other histotypes, including NETs of the gastrointestinal tract. Conversely, Enterobius vermicularis has not yet been claimed to participate in the onset of pre-cancerous conditions or tumours. The rare occurrence of contemporary appendiceal NETs and parasitic infection, raises the intriguing hypothesis of an inflammation-related carcinogenesis, although a cause-effect relationship cannot be established. Larger international series of childhood appendiceal NETs, which also include countries with higher prevalence of parasitic bowel infections, are needed to further clarify this possible cause-effect relationship.

Mesenchymal hamartoma of the chest wall (MHCW) is a rare neonatal benign tumor with an estimated incidence of 1 in 3 000 among primary bone tumors, and 1 in one million in the general population. Traditionally, the treatment of choice was an "en bloc" resection, but surgery limited to symptomatic cases, is now suggested by most authors due to the numerous cases of spontaneous regressions. We report 2 patients of symptomatic MHCW, characterized by progressive respiratory distress, who underwent surgical treatment with prompt resolution of symptoms. Surgeons and neonatologists should be aware of this rare condition and its possible fatal or nearly-fatal complications.
