Background: Ganglioneuroblastoma intermixed (GNBi) and ganglioneuroma (GN) represent benign variants of peripheral neuroblastic tumours. While historically surgical resection was recommended, watchful active observation has become the accepted management for a subset of patients., Objectives: To review clinical features, biology, natural history and management of a retrospective UK CCLG study cohort of GN and GNBi, and compare outcomes of patients treated with surgical resection or watchful active observation., Methods: Retrospective review of histologically confirmed non-metastatic GN and GNBi diagnosed between 1990 and 2020., Results: A total of 259 patients were identified (163 GN, 93 GNBi, median age 62 months). In all 201 (78%) had initial surgery and 58 (22%) were observed. Overall survival was 98%. Twenty-one of 58 observed (36%) required subsequent surgery due to progressive tumour growth (52%). Gross total resection (GTR) was achieved in 79% of patients with a 19% complication rate. GTR was obtained in a similar proportion of patients having initial surgery (65%) and delayed surgery (76%). Patients obtaining GTR were more likely to have complete symptom(s) control (43% vs. 24%). In 45 cases (39%), surgical pathology was different from pathology at biopsy, and in 14 (12%) the pathology changed from GN/GNBi to neuroblastoma/GNB nodular., Conclusion: Watchful active observation can be a safe approach, with surgical resection reserved for symptomatic patients. However, a small proportion of patients in the observation group had their diagnosis revised to malignant at surgery. Careful assessment of surgical risk and expected benefits, after considering an initial period of observation, will allow clinicians to make optimal decisions for patients and their families., (© 2024 The Author(s).

Aim  Pneumatosis intestinalis (PI) is a condition in which multiple gas-filled cysts form within the wall of the gastrointestinal tract in either the subserosa or submucosa. The presence of pneumoperitoneum in the presence of PI can present a therapeutic dilemma. The aim of our study was to review our experience and management of this condition. Methods  A single-center retrospective study of consecutive children (> 1 year) presenting with a pneumoperitoneum and evidence of PI (2009-2015). Demographics, case notes, microbiology, and imaging were reviewed. Results  Seven patients were identified (four males; age range 5-14 years). Four children had global developmental delay and were percutaneous endoscopic gastrostomy or jejunostomy fed, one was immunocompromised (acute lymphoblastic leukemia). The others had encephalitis and eosinophilic gastroenteritis. One patient proceeded to an exploratory laparotomy; no perforation was identified, pneumatosis of the colon was observed, and a loop ileostomy was formed. The remaining six were managed conservatively and made nil by mouth with intravenous antibiotics commenced. Five of the six had a computed tomography (CT) scan which revealed PI and free air with no other worrying signs. One died from nongastrointestinal causes, while the remaining five had feeds reintroduced uneventfully. Conclusion  Free air in the setting of PI may represent rupture of the gas cysts and not always transmural perforation. Surgery may not always be indicated and conservative management may suffice. A CT scan can be useful for excluding other intra-abdominal pathological findings and continued clinical assessment is essential., (Georg Thieme Verlag KG Stuttgart · New York.)
