PURPOSE: We examined the question of whether one-hand chest compression for a small child could compress intraabdominal organs. METHODS: We retrospectively examined medical charts and multidirectional computed tomography (MDCT) images obtained from children aged 1 to 18 years who presented to the hospital from March 2002 to March 2012. We measured the length of the sternum (Stotal) and the length of the lower half of the sternum (Stotal/2~X). We also measured the distance from the diaphragm to the midpoint of the sternum (Stotal/2~D) and half the width of an adult hand (Wtotal/2). Finally, we counted the number of instances at each age in which Stotal/2~X and Stotal/2~D were less than Wtotal/2. RESULTS: This study included records and MDCT images for 301 children with a mean age of 12.05+/-5.59 years. We also enrolled 47 adult rescuers (25 men, 53.2%) with a mean age of 23.20+/-2.13 years. The mean Wtotal/2 was 4.62+/-0.46 cm. All 1-year-old children had Stotal/2~X and Stotal/2~D less than Wtotal/2. Among children aged 2 years, six (60.0%) had Stotal/2~X and Stotal/2~D less than Wtotal/2. Among children aged 3 years, four (26.7%) had Stotal/2~X and Stotal/2~D less than Wtotal/2, and among those aged 4 years, two (13.3%) had Stotal/2~X and Stotal/2~D less than Wtotal/2. However, Stotal/2~X and Stotal/2~D were greater than Wtotal/2 in children aged 5 years or more. CONCLUSION: Our measurements indicate that one-hand chest compression for a small child could cause intraabdominal organ injury.

Purpose: Patients who have undergone gastrectomy have unique symptoms that are not appropriately assessed using currently available tools. This study developed and validated a symptom-focused quality of life (QoL) questionnaire for patients who have received gastrectomy for gastric cancer. Materials and Methods Based on a literature review, patient interviews, and expert consultation by the KOrean QUality of life in Stomach cancer patients Study group (KOQUSS), the initial item pool was developed. Two large-scale developmental studies were then sequentially conducted for exploratory factor analyses for content validity and item reduction. The final item pool was validated in a separate cohort of patients and assessed for internal consistency, test-retest reliability, construct validity, and clinical validity. Results The initial questionnaire consisted of 46-items in 12 domains. Data from 465 patients at 11 institutions, followed by 499 patients at 13 institutions, were used to conduct item reduction and exploratory factor analyses. The final questionnaire (KOQUSS-40) comprised 40 items within 11 domains. Validation of KOQUSS-40 was conducted on 413 patients from 12 hospitals. KOQUSS-40 was found to have good model fit. The mean summary score of the KOQUSS-40 was correlated with the EORTC QLQ-C30 and STO22 (correlation coefficients, 0.821 and 0.778, respectively). The KOQUSS-40 score was also correlated with clinical factors, and had acceptable internal consistency (> 0.7). Test-retest reliability was greater than 0.8. Conclusion The KOQUSS-40 can be used to assess QoL of gastric cancer patients after gastrectomy and allows for a robust comparison of surgical techniques in clinical trials.

PURPOSE: The information committee of the Korean Society for Metabolic and Bariatric Surgery (KSMBS) performed the nationwide survey of bariatric and metabolic operations to report IFSO (International Federation for the Surgery of Obesity and Metabolic Disorders) worldwide survey annually. This study aimed to report the trends of bariatric and metabolic surgery in Korea in 2014–2017. MATERIALS AND METHODS: We analyzed the accumulated nationwide survey data conducted for annual ISFO survey from 2014 to 2017. Trends such as the number of operations by hospital type and the number of operations by surgical method were analyzed. RESULTS: The number of operations has decreased sharply in 2015 comparing to 2014 (913⇒550). The number of operations performed in private hospitals dropped sharply from 529 to 250, 198, and 103 cases. The number of revisional surgeries increased to 223 in 2015. The primary surgery number fell from 757 in 2014 to 327 in 2015. In primary surgery, sleeve gastrectomy was gradually increased from 2014 to 143 (18.9%), 105 (32.1%), 167 (47.2%) and 200 (56.3%) and became the most frequently performed surgery. On the other hand, the incidence of adjustable gastric band decreased gradually from 439 (58.0%) to 117 (35.8%), 112 (31.6%) and 59 (16.6%). CONCLUSION: The overall number of obesity metabolic operations has decreased since 2014, especially the number of adjustable gastric band, and the number of operations in private hospitals declined sharply. On the other hand, the number of operations in university hospitals did not change much, and the number of sleeve gastrectomy increased.
