Short-Term Efficacy and Quality of Life of Gastric Cancer Patients Undergoing Radical Gastrectomy Assisted by External Vision

Abstract

Objective. To evaluate the clinical effects and survival prognosis of radical gastrectomy assisted by external vision in gastric cancer. Methods. A total of 60 hospitalized gastric cancer patients from June 2016 to December 2018 were selected and divided into the observation group and control group according to different surgical procedures. The control group was treated with traditional open radical gastrectomy, while the observation group was treated with radical gastrectomy assisted by an external vision microscope. Relevant surgical indicators, visual analogue scale (VAS), postoperative complications, and life quality assessment were analyzed and compared between the two groups. Results. The incision length and intraoperative blood loss in the observation group were smaller than those in the control group, and the difference was statistically significant ( $P<0.05$ ); compared with the control group, the observation group had significantly shorter hospital stay, earlier postoperative first exhaust time, and lower gastric fluid volume at the 3rd day after surgery ( $P<0.05$ ). The pain scores of the observation group at 1, 4, and 12 weeks after surgery were lower than those of the control group ( $P<0.05$ ), and the difference was significant. The quality of life scores at the 1st week and 12th week after surgery showed that the dysphagia symptom scores of the observation group and the control group were significantly reduced but the two groups had significant differences in fatigue, physical function, pain score, postoperative pain, and overall quality of life. The observation group was significantly better than the control group ( $P<0.05$ ). Follow-up studies showed no significant difference between mortality and cancer recurrence ( $P>0.05$ ); the patients recovered well at postoperation, and the diet of the observation group was better than that of the control group ( $P<0.05$ ); gastric reflux and knife pain were less than those of the control group ( $P<0.05$ ). Conclusion. Radical gastrectomy assisted by external vision for gastric cancer yields clinical benefits for gastric cancer patients, which not only dramatically shortened the length of hospital stay but also effectively ameliorated the quality of life of patients, all indicating that external vision-assisted surgery was significantly better than traditional gastrectomy in improving the postoperative quality of life of gastric cancer patients in the absence of increasing the risk of adverse events.
