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.

Lymphatic malformations (LMs) are congenital malformations of the lymphatic system which can be effectively treated by sclerotherapy. This study aims to evaluate the efficacy of doxycycline in the treatment of LMs.

We retrospectively reviewed the medical records of all patients who were diagnosed as LMs and underwent doxycycline sclerotherapy in Asan Medical Center between March 2013 and February 2014. Thirty-five sclerotherapy procedures were performed on 21 patients. The procedures were performed under general anesthesia. After each treatment, the clinical and radiographic response was characterized as complete (≥80% decrease in lesion size), partial (<80% decrease of size), or no response (no decrease of size).

There were 11 male patients and 10 female patients. The median age of sclerotherapy was 21 months (range, 2–180 months). The most common location was cervicofacial (52.3%), followed by extremity (28.6%) and truncal (19.0%). The most common lesion type was macrocystic (71.4%), followed by microcystic (28.5%). There was one (2.8%) skin necrosis which was recovered by wound management. Thirty-eight percent of patients had a complete response, 47.6% of patients had a partial response and 14.3% of patients had no response. Median frequency of treatment was one (range, 1–5). No response group consisted of all microcystic type.

Sclerotherapy with Doxycycline is safe and effective for macrocystic LMs.

This study aimed to compare the outcomes of open fundoplication (OF) and laparoscopic fundoplication (LF) in children with gastroesophageal reflux disease (GERD).

We retrospectively reviewed the electronic medical charts of pediatric patients who underwent fundoplication for GERD between January 2005 and May 2018 at the Korean tertiary hospital. Patient characteristics, operation type, associated diagnosis, operation history, neurologic impairment, postoperative complication, recurrence, and operation outcomes were investigated. The Mann-Whitney U test or Student's t-test was used to evaluate continuous data as appropriate. The χ² test was used to analyze categorical data.

A total of 92 patients were included in this study; 50 were male and 42 were female. Forty-eight patients underwent OF and 44 patients underwent LF. Patient characteristics, such as sex ratio, gestational age, symptoms, neurological impairment, and history of the previous operation were not different between the two groups. A longer operative time (113.0±56.0 vs. 135.1±49.1 minutes, p=0.048) was noted for LF. There was no significant difference in operation time when the diagnosis was limited to only GERD, excluding patients with other combined diseases. Other surgical outcomes, such as intraoperative blood loss, transfusion rate, hospital stay, and recurrence rate were not significantly different between the 2 groups. The complication rate was slightly higher in the OF group than in the LF group; however, the difference was not significant (20.8% vs. 11.4%, p=0.344).

LF is as safe, feasible, and effective as OF for the surgical treatment of GERD in children.
