Application value of mixed reality technology in surgical conversation of laparoscopy radical resection of gastric cancer: a prospective study / 中华消化外科杂志

ABSTRACT

Objective:To investigate the application value of mixed reality technology in surgical conversation of laparoscopy radical resection of gastric cancer.Methods:The prospective randomized controlled study was conducted. There were 80 family members of patients with gastric cancer who were admitted to Nanfang Hospital of Southern Medical University from June 2021 to December 2022 being selected as subjects. All patients underwent laparoscopic radical resection of gastric cancer. Based on random number table, all subjects were allocated into the control group and the experiment group. Subjects in the control group performed routine surgical conversation and subjects in the experiment group performed surgical conversation based on mixed reality technology. Observation indicators: (1) baseline data of the subjects; (2) anxiety assessment of the subjects. Measurement data with normal distribution were represented as Mean± SD, and the independent sample t test was used for inter-group comparison. Repeated measurement data were analyzed using the repeated ANOVA. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test. Comparison of ordinal data was conducted using the Wilcoxon rank sum test. Results:(1) Baseline data of the subjects. A total of 80 subjects were selected for eligibility, including 40 subjects in the control group and 40 subjects in the experi-ment group. There were 44 males and 36 females, aged (40±9)years. The gender (male, female), age, education background (primary school education, middle school education, high school education, junior college education, undergraduate education, postgraduate education) were 23, 17, (39±9)years, 1, 3, 9, 16, 9, 2 in subjects of the control group, versus 25, 15, (42±10)years, 0, 8, 6, 11, 14, 1 in subjects of the experiment group, showing no significant difference in the above indicators between the two groups ( χ2=0.20, t=?1.64, Z=?0.10, P>0.05). (2) Anxiety assessment of the subjects. The scores of self-rating Anxiety Scale (SAS) and Hospital Anxiety Scale (HADS) before surgical conversation, after surgical conversation, after surgery were 41±10 and 26±5, 49±11 and 32±3, 40±13 and 15±8 in subjects of the control group, versus 44±9 and 23±3, 66±16 and 28±6, 34±14 and 8±3 in subjects of the experiment group, showing significant differences in the above indicators between the two groups ( FSAS组间=8.83, FSAS时间=40.41, FSAS交互=12.21, FHADS组间=32.42, FHADS时间=321.28, FHADS交互=6.15, P<0.05). Conclusion:Compared with traditional surgical conversation, mixed reality technology based surgical conversation can relieve the postoperative conxiety of subjects.
