Background: In emergency general surgery (EGS), rapid judgement and prompt emergency surgery play a significant role in determining the patient's prognosis. This study aimed to evaluate whether implementing the acute care surgery (ACS) system in Korea has improved the clinical outcomes of patients.
Methods: This retrospective cohort study was conducted at three tertiary hospitals in Korea.
Purpose: Over the past 3 years, approximately 23,000 emergency surgeries were performed annually in South Korea, accounting for >1% of all surgeries nationwide. With the growing necessity for treating these emergency cases with dedication and proficiency, acute care surgery (ACS) teams were appointed at various hospitals. Regarding the implications of the ACS team, many studies showed promising results with a shorter time from the emergency department (ED) to the operating room (OR), shorter length of stay, and fewer complications.

- This study compared resting energy expenditure (REE) measured through indirect calorimetry to estimates from predictive equations in severe trauma patients to assess caloric needs.
- A total of 27 patients had their REE measured, finding that weight-based and Penn State 2003 equations provided the closest estimates, while Harris-Benedict and Ireton-Jones equations significantly differed from measured values.
- The findings suggest a crucial need for direct measurement of REE in severe trauma patients rather than relying on predictive equations, as the latter showed a 36.2% concordance rate with measured values.
Article Synopsis
- A nationwide study in Korea was conducted to compare laparoscopic emergency surgery (LES) with open abdominal emergency surgery (OES), analyzing data from 2,122 patients across three hospitals from 2014 to 2019.
- The results showed that 60.3% of patients underwent OES, with the small bowel being the most commonly operated organ, while the appendix was most common for LES, particularly in appendectomies (93.7% LES) and cholecystectomies (88.0% LES).
- The study found that while LES practices in Korea are similar to global trends for some surgeries, differences exist in gastric and colorectal surgeries, highlighting the need for further research to understand these vari
Rice fields are important habitats for a variety of water birds, and their importance is increasing with the destruction of natural wetlands. This study was conducted to understand the foraging strategy of the black-faced spoonbill, an internationally endangered species, in rice fields. To achieve this objective, the feeding success rate of black-faced spoonbills in rice fields was analyzed considering the species' feeding behavior, environmental factors, and external factors.
