Professor Yuki Ushimaru's research lab specializes in surgical oncology with a focus on optimizing outcomes for elderly and high-risk patients with gastric cancer. The lab investigates minimally invasive surgical techniques, such as laparoscopic gastrectomy, and evaluates perioperative strategies to improve survival and reduce complications. A key emphasis is placed on personalized preoperative care, including comprehensive geriatric assessment (CPAS), to enhance surgical safety and long-term outcomes. The lab also explores endoscopic physiology, particularly insufflation pressure in gastrointestinal endoscopy, to improve visualization and procedural efficacy.
Figures are computed from collected data and may differ slightly.
PG group exhibited better perioperative performance. Furthermore, better nutritional results were obtained in the PG group. Although the late stenosis and reflux symptoms must be addressed, the PG is a preferable surgical procedure for the treatment of early proximal gastric cancer.
LG for resectable advanced gastric cancer was not inferior to OG in terms of both short-term and long-term outcomes regardless of patient age. In elderly patients, LG may improve overall survival by reducing mortality from respiratory diseases.
In flexible gastrointestinal (GI) endoscopy, endoscopic insufflation is crucial and directly affects visualization. Optimal visualization enables endoscopists to conduct better examinations and administer optimal treatments. However, endoscopic insufflation is typically performed manually and is subjective. We aimed to measure the GI endoluminal pressure during flexible GI endoscopy. Participants underwent esophagogastroduodenoscopy (EGD) at our endoscopy center. Pressure measurement was conduct
Hiatal hernia was found in 20.7% of patients who received surgical treatment for achalasia, but no cases were diagnosed prior to surgery.
In elderly gastric cancer patients, managing advanced age, low BMI, high CCI, and minimizing postoperative complications are essential for reducing non-cancer-related mortality following curative surgery.
Implementing CPAS significantly enhances surgical safety and reduces complication rates in elderly gastric cancer patients, emphasizing the critical role of personalized preoperative care in surgical oncology for this demographic.
