Trauma Care Systems in Urban Areas: Our Thoughts on the Contrasting Approaches in South Korea and Japan.

Trauma is a major global health issue, causing significant mortality, disability, and healthcare expenses. Since 2012, the Ajou Trauma Center in South Korea has been at the forefront, providing centralized severe trauma care for a population of 9.5 million. In 2022, the center managed 3,500 cases of severe trauma, including 500 helicopter transports, and conducted 2,800 surgeries, with 450 addressing torso trauma. Its exceptional performance has garnered global recognition, solidifying its position among the top advanced trauma centers. In Tokyo, critically ill and major trauma patients are currently transported to the nearest emergency and critical care centers, each serving a population of approximately 0.5 to 0.6 million people. Due to the low incidence of trauma per facility and an aging population, implementing a high level of trauma care and a comprehensive training framework within Japan's existing system poses significant challenges. A comparative analysis of South Korea's centralized system and Tokyo's decentralized approach indicates that the centralized system may lead to the establishment of a more advanced trauma center with ethical and equity considerations, compared to the decentralized approach. Therefore, consolidating major trauma cases in Tokyo shows promise for establishing exceptional trauma centers. This emphasizes the urgent need for Japan to take immediate steps towards a more robust future in trauma care. This assertion aligns with the global discourse on improving trauma care practices and could make a valuable contribution to the scholarly literature on trauma care systems.

Pancreaticoduodenectomy after neoadjuvant chemotherapy for gastric cancer invading the pancreatic head: A case report.

BACKGROUND: Pancreaticoduodenectomy (PD) for advanced gastric cancer is rarely performed because of the high morbidity and mortality rates and low survival rate. However, neoadjuvant chemotherapy for advanced gastric cancer has improved, and chemotherapy combined with trastuzumab may have a preoperative tumor-reducing effect, especially for human epidermal growth factor receptor 2 (HER2)-positive cases. CASE SUMMARY: We report a case of successful radical resection with PD after neoadjuvant S-1 plus oxaliplatin (SOX) and trastuzumab in a patient (66-year-old male) with advanced gastric cancer invading the pancreatic head. Initial esophagogastroduodenoscopy detected a type 3 advanced lesion located on the lower part of the stomach obstructing the pyloric ring. Computed tomography detected lymph node metastasis and tumor invasion to the pancreatic head without distant metastasis. Pathological findings revealed adenocarcinoma and HER2 positivity (immunohistochemical score of 3 +). We performed staging laparoscopy and confirmed no liver metastasis, no dissemination, negative lavage cytological findings, and immobility of the distal side of the stomach due to invasion to the pancreas. Laparoscopic gastrojejunostomy was performed at that time. One course of SOX and three courses of SOX plus trastuzumab were administered. Preoperative computed tomography showed partial response; therefore, PD was performed after neoadjuvant chemotherapy, and pathological radical resection was achieved. CONCLUSION: We suggest that radical resection with PD after neoadjuvant chemotherapy plus trastuzumab is an option for locally advanced HER2-positive gastric cancer invading the pancreatic head in the absence of non-curative factors.

Distal gastric tube resection with vascular preservation for gastric tube cancer: A case report and review of literature.

BACKGROUND: Survival rates in patients with esophageal cancer undergoing esophagectomy have improved, but the prevalence of gastric tube cancer (GTC) has also increased. Total resection of the gastric tube with lymph node dissection is considered a radical treatment, but GTC surgery is more invasive and involves a higher risk of severe complications or death, particularly in elderly patients. CASE SUMMARY: We report an elderly patient with early GTC that had invaded the duodenum who was successfully treated with resection of the distal gastric tube and Roux-en-Y (R-Y) reconstruction. The tumor was a type 0-IIc lesion with ulcer scars surrounding the pyloric ring. Endoscopic submucosal resection was not indicated because the primary lesion was submucosally invasive, was undifferentiated type, surrounded the pyloric ring, and had invaded the duodenum. Resection of distal gastric tube with R-Y reconstruction was safely performed, with preservation of the right gastroepiploic artery (RGEA) and right gastric artery (RGA). CONCLUSION: Distal resection of the gastric tube with preservation of the RGEA and RGA is a good treatment option for elderly patients with cT1bN0 GTC in the lower part of the gastric tube.
