Most children with tumors will require one or more surgical interventions as part of the care and treatment, including making a diagnosis, obtaining adequate venous access, performing a surgical resection for solid tumors (with staging and reconstruction), performing procedures for cancer prevention and its late effects, and managing complications of treatment; all with the goal of improving survival and quality of life. It is important for surgeons to adhere to sound pediatric surgical oncology principles, as they are closely associated with improved local control and survival. Unfortunately, there is a significant disparity in survival rates in low and middle income countries, when compared to those from high income countries.The International Society of Paediatric Surgical Oncology (IPSO) is the leading organization that deals with pediatric surgical oncology worldwide. This organization allows experts in the field from around the globe to gather and address the surgical needs of children with cancer. IPSO has been invited to contribute surgical guidance as part of the World Health Organization Initiative for Childhood Cancer. One of our goals is to provide surgical guidance for different scenarios, including those experienced in High-(HICs) and Low-and Middle-Income Countries (LMICs). With this in mind, the following guidelines have been developed by authors from both HICs and LMICs. These have been further validated by experts with the aim of providing evidence-based information for surgeons who care for children with cancer.We hope that this initiative will benefit children worldwide in the best way possible.

Although weekly oxaliplatin in combination with infusional 5 fluorouracil produces durable remissions in esophageal cancer, the regimen used in this trial was not acceptable for routine use. Future protocols should incorporate lower chemotherapy doses.

Microgastria is a very rare anomaly characterized by a very small tubular stomach that presents with severe gastroesophageal reflux disease due to the small reservoir capacity of the stomach. We present a patient with microgastria-related reflux and a failed fundoplication who was treated with total esophageal gastric dissociation (TEGD) resulting in an excellent outcome. In our experience with this good long-term result, we would suggest that TEGD be added to the armamentarium of procedures that can be used in the treatment of microgastria.
