The Korean Association of Pediatric Surgeons (KAPS) performed a nationwide survey on sacrococcygeal teratoma in 2018.

The authors reviewed and analyzed the clinical data of patients who had been treated for sacrococcygeal teratoma by KAPS members from 2008 to 2017.

A total of 189 patients from 18 institutes were registered for the study, which was the first national survey of this disease dealing with a large number of patients in Korea. The results were discussed at the 34th annual meeting of KAPS, which was held in Jeonju on June 21–22, 2018.

We believe that this study could be utilized as a guideline for the treatment of sacrococcygeal teratoma to diminish pediatric surgeons' difficulties in treating this disease and thus lead to better outcomes.

The aim of this study was to analyze of the risk factors for surgical procedure on ileo-colic intussusception without leading point in children.

We retrospectively reviewed medical records of patient treated for ileo-colic intussusception between January 2003 and December 2014. We exclude the patients who had leading point. Because of the large difference on patient's numbers between non-operative group (cases of ileo-colic intussusceptions successfully reduced by air reduction) and operative group (cases underwent operation due to failed air reduction), we compared the data of operative group of patients without leading point between 2003 and 2014 with the data of non-operative group as control group from 2013 to 2014. Clinical features such as gender, age, body temperature, body weight in diagnosis, growth curves for age-gender-body weight, and laboratory data of blood test were compared.

In non-operative group, total 94 patients who were treated successfully by the non-operative air reduction. In operative group, total 21 patients treated by surgical procedure. The age under 12 months, weight over upper 75 percentile group, increased segment neutrophil count, decreased hemoglobin level and lymphocyte count were significantly associated with a requirement for surgical procedure.

We conclude that younger age, higher weight percentile group, increased segment neutrophil, decreased hemoglobin and lymphocyte are the independent risk factors related to operative treatment for ileo-colic intussusception in children. If primary air reduction is failed in patients with such risk factors, operative treatment over ultrasonography or secondary reduction can prevent unnecessary effort and complications, thus emphasizing the consideration of operative treatment when selecting treatment methods.
