Summary
Intelligent algorithm-based MRI aids gastric cancer surgery. 3D laparoscopy reduces operation time and blood loss compared to 2D laparoscopy, with similar short-term outcomes.
Area of Science:
- Oncology
- Surgical Technology
- Medical Imaging
Background:
- Gastric cancer necessitates effective surgical interventions.
- Laparoscopic radical gastrectomy is a common treatment approach.
- Advancements in imaging and surgical techniques are crucial for improving patient outcomes.
Purpose of the Study:
- To evaluate the influence of intelligent algorithm-based magnetic resonance imaging (MRI) on the short-term curative effects of laparoscopic radical gastrectomy for gastric cancer.
- To compare the efficacy of 3D versus 2D laparoscopic surgery in terms of operative parameters and postoperative recovery.
Main Methods:
- A convolutional neural network (CNN) algorithm was employed for MRI image segmentation in gastric cancer patients.
- 158 patients were randomized into 3D laparoscopy and 2D laparoscopy groups (79 each).
- Key outcomes including operation time, blood loss, lymph node dissection, and postoperative recovery metrics were analyzed.
Main Results:
- The CNN algorithm demonstrated high accuracy in image segmentation (DSC: 0.89, sensitivity: 0.93).
- The 3D laparoscopic group exhibited significantly shorter operation times and reduced intraoperative blood loss compared to the 2D group (P < 0.05).
- No significant differences were observed in lymph node dissection, postoperative recovery times, or complication rates between the groups.
Conclusions:
- The developed CNN algorithm accurately segments target areas, supporting preoperative examination for gastric cancer.
- 3D laparoscopic surgery offers advantages in reducing operative time and blood loss for gastric cancer patients.
- Both 3D and 2D laparoscopic approaches provide comparable short-term curative effects for gastric cancer.
