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.

Single-port laparoscopy-assisted surgery is being performed for various operations in pediatric patients recently. The aims of this study were to prove the safety and find well-matched indications of small bowel resection using single-site umbilical laparoscopic surgery (SSULS).

From 2011 to 2016, 29 pediatric patients underwent SSULS. Medical records were retrospectively reviewed.

A total of 29 patients were included and 30 SSULS were performed in this study. The mean age at operation was 5.7 years, and the mean weight was 21.9 kg. Meckel's diverticulum was the most common indication for SSULS, followed by small bowel intussusception due to leading point mass, small bowel duplication, and Crohn's disease. In most cases, estimated blood loss was negligible except in Crohn's disease with severe inflammation. While answering post-discharge questions about scars, most parents responded that they were satisfied with the postoperative wound.

SSULS is a useful operation to try even for surgeons who do not have advanced laparoscopic skills. Complication rates of single-port operations do not differ from those of conventional laparoscopic operations. Most lesions of the small bowel could be indications of SSULS. Careful attention is required when performing SSULS in patients with Crohn's disease.

The duplication of gastrointestinal tract has been known to be a rare condition and two different forms, cystic and tubular type. This study was conducted to examine its clinical characteristics, especially cystic enteric duplication which was detected antenatally or postnatally.

There were 13 patients, who confirmed as cystic enteric duplication after operation between July 1996 and June 2015. Clinical data, including a gender, age at operation, presenting symptoms, diagnostic modalities, locations of lesion, and results of surgical treatment, were reviewed retrospectively according to cases detected antenatally and postnatally.

Five cases were included in antenatal diagnosis group and 8 cases in postnatal diagnosis group. Both groups show slightly common in female and the lesion most common in ileum. Antenatal diagnosis group shows 2 males and 3 females and the mean age at operation was 12±52 days (range, 5 to 90 days). They received operation regardless of symptom. Postnatal group shows 3 males and 5 females and the mean age at operation was 462.5±777.0 days (range, 4 days to 6 years). Moreover, 6 patients (75.0%) were age before 2 years. They usually presented abdominal pain with vomiting.

Cystic enteric duplication could present symptoms at any time during childhood, mainly before 2 years old, and so a proper management should be considered when suspect it. Although it is uncommon, surgical management including a minimal invasive procedure could be attempted despite the neonatal period.
