Abstract:

Objective To explore the efficacy of linaclotide in treating colonic obstruction in patients with functional constipation. Method From June 2019 to June 2022, 80 patients with colonic obstruction caused by functional constipation who were diagnosed and treated by the Eighth People's Hospital of Qingdao City were randomly divided into a control group and an observation group, with 40 patients in each group. The patients in the control group received routine treatment, including general treatment, anal exhaust, and enema. The observation group was treated with linaclotide on the basis of the control group. Compare the efficacy, frequency of defecation, stool characteristics, abdominal distension, sense of difficulty in defecation, abdominal pain scores, constipation

specific quality of life scores, and the occurrence of adverse reactions between the two groups. Result The efficacy of the observation group was 95.00%, significantly higher than that of the control group (77.50%), with a significant difference (P ＜ 0.05). Before treatment, there was no significant difference between the two groups in stool characteristics, defecation frequency, abdominal distension, sense of difficulty in defecation, abdominal pain scores, and constipation specific quality of life scores (P ＞ 0.05); After treatment, the stool characteristics, defecation frequency, and abdominal distension, defecation exertion, abdominal pain scores, and constipation specific quality of life scores of the two groups of patients were significantly increased, and the range of change in the observation group was significantly higher than that in the control group (P ＜ 0.05). During the treatment period, the incidence of adverse reactions was 12.50% in the observation group and 10.00% in the control group, with no significant

difference (P ＞ 0.05). The recurrence rate in the observation group was 2.50%, significantly lower than that in the control group (15.00%), with a significant difference (P ＜ 0.05). Conclusion Linaclotide is effective in improving the clinical outcomes of patients with functional constipation and colonic obstruction.
