Study on Ultrasonographic Diagnosis and Postoperative Comprehensive Nursing of Rectal Cancer in Preoperative Staging

The aim of this study is to evaluate the value of ultrasonography in preoperative T staging of rectal cancer and to study the effect of psychological nursing and colostomy nursing in patients with rectal cancer after colostomy. In this study, a retrospective comparative analysis was conducted on 41 patients with colostomy after rectal cancer surgery who had been treated in a hospital from June 2020 to June 2021 and 41 patients who only had general nursing. By analysis, 42 cases were detected by TRUS. Ultrasonic stage (uT) was consistent with pathological stage (pT) in 32 cases, and the coincidence rate was 76%. The tumor length and short diameter measured by 0RUS were not significantly related to pT (P = 0.083, 0.499), while the invasion diameter was related to pT (P = 0.015). The scores of SAS and SDS in the nursing group were significantly lower than those in the conventional group, and the degree of depression and anxiety in the nursing group was significantly improved (P < 0.05). The quality-of-life score in the nursing group was significantly higher than that in the conventional group (P < 0.05), and the daily living ability, regular defecation, and self-care ability of ostomy in the nursing group were significantly improved. The nursing satisfaction of patients in the nursing group was 95.12%, while that in the conventional group was 80.49%. The nursing satisfaction of patients in the experimental group was significantly higher than that in the conventional group (P < 0.05). Therefore, for most patients with rectal cancer, TRUS is an effective means of T staging. When it is difficult to determine the depth of tumor invasion, combining the invasion circumference can improve the accuracy of staging. Conventional nursing combined with psychological nursing and colostomy nursing for patients with rectal cancer after colostomy can effectively relieve patients' bad emotions, improve patients' self-care ability, and satisfaction degree toward nursing and application of nursing is high.
