Enhancing safety of laparoscopic vascular control for neonatal sacrococcygeal teratoma
Life-threatening bleeding is a hazard of major tumor excision in children. However, fatalities from inadvertent arterial ligation should not be overlooked. Sacrococcygeal teratoma is the commonest neonatal tumor. Laparotomy to ligate the median sacral artery has been used to preempt potentially fatal resectional bleeding. Use of laparoscopy to achieve the same is an evolving technique, with only 7 neonatal cases described. As such, the Idea, Development, Exploration, Assessment, Long-term study (IDEAL) guidelines on surgical innovation recommend case reports addressing proof of concept, technical factors and safety tips.Laparoscopic excision of a retroperitoneal lymphatic malformation in a newborn
Abdominal lymphatic malformations may be challenging to eradicate. Retroperitoneal lesions may more difficult to resect than mesenteric ones; however, the latter may predispose to intestinal volvulus, leading to calls for their prompt excision. Such lesions identified perinatally may pose particular challenges: in one case, respiratory failure caused by abdominal distension required emergency drainage followed by later laparoscopic excision; laparoscopy has also been used promptly to diagnose and resect neonatal mesenteric lymphatic malformations with their inherent volvulus risk.Excision of extensive metastatic dysgerminoma to control refractory hypercalcaemia in a child at high risk for tumour-lysis syndrome
Hypercalcaemia is a rare life-threatening complication of paediatric cancer that is commoner in haematological than solid malignancies and associated rarely with acute renal failure. Often refractory to medical therapy, control of hypercalcaemia in children with solid tumours may necessitate excision of localised tumours or urgent chemotherapy for metastatic ones. We present a child with refractory hypercalcaemia, bulky chemosensitive metastatic tumours and acute renal failure in whom chemotherapy posed high-risk of tumour lysis syndrome (TLS).Excision of ganglioneuroma from skull base to aortic arch
High retropharyngeal neuroblastic tumors in children have been excised and debulked transorally or cervically, often with a covering tracheostomy. Although we and others have approached high thoracic lesions thoracoscopically, the trapdoor incision (or modification thereof) is generally reserved for cervicothoracic tumors with significant vessel encasement around the thoracic inlet. We report a case of symptomatic ganglioneuroma extending from the nasopharynx, at the level of the skull base, down to the aortic arch: macroscopic clearance was achieved via an extended trapdoor incision and without recourse to tracheostomy, transoral surgery, or transfusion.
