The current study was to assess the application effects of conventional surgical techniques and ultrasound-guided precise localization technology for early gastric cancer (EGC), with an emphasis on long-term survival, postoperative complica
To evaluate perioperative results, postoperative complications, and long-term survival in order to conduct a thorough comparison between conventional sur
Of 100 EGC patients were gathered, and they were subsequently divided into two groups based on the surgical technique used: The observation group (n = 52) received surgery assisted by ultrasound-guided precise localization technology, whereas the control group (n = 48) received traditional surgical treatment. The baseline characteristics were similar between the groups. Operation time, intrao
Compared with the control group, the observation group had significantly less intraoperative blood loss (80 mL vs 120 mL, P < 0.05) and more dissected lymph nodes (28 vs 22, P < 0.05). There were fewer postoperative complications in the observation group than in the routine group (8% vs 16%, P < 0.05), hospitalization after surgery was shorter, and gastrointestinal function returned sooner. The long-term survival rates at 5 years and 3 years were significantly greater in the observation group than in the control group: 82% and 88% vs 70% and 78%, respectively (P < 0.05).
It is possible that ultrasound-guided accurate localization technology might be utilized more widely in clinical practice because it could significantly enhance the results of surgery for EGC, including reduced blood loss, better lymphadenectomy, lower complication rates, and improved survival rates. Further studies should aim to refine this technology and consider its utility in other types of oncologic surgery.
Core Tip: The ultrasound-guided accurate localization technique greatly increases the surgical effect on patients with early gastric cancer, including a clearer tumor margin, shorter operation time, reduced intraoperative blood loss, greater degree of lymph node dissection, and fewer postoperative complications. This was a retrospective study that revealed that ultrasound surgery results in better 3- and 5-year survival rates than traditional surgery does. In vivo imaging allows for improved anatomical guidance to enhance accurate tumor resection and careful lymphadenectomy. These findings indicate that ultrasound guidance should be considered a routine procedure in clinical practice to increase surgical accuracy, accelerate recovery, and increase the long-term survival of patients with early gastric cancer.
