Chronic Functional Constipation, Clinical Study

Vibrating Capsule, cohort study, Chronic Functional Constipation

This study is a multi-center prospective cohort study, which plans to include 600 patients with chronic functional constipation to treat with Vibrabot capsules and patients will be grouped according to subtypes. During the study, the patients' basic information, baseline constipation status and treatment information, capsule intake during treatment, and concomitant medication will be collected. During the treatment phase, patients follow the doctor's advice to receive Vibrabot capsule treatment and maintain stable dietary intake and exercise according to the constipation diagnosis and treatment guidelines. During the study, patients need to fill in the relevant information during the treatment in the electronic questionnaire in a timely and truthful manner. The treatment effect of the patients is evaluated by assessing the number of occurrences of spontaneous bowel movements (SBM) and complete spontaneous bowel movements (CSBM).

Constipation is characterized by a decrease in bowel movements, dry and hard stools, and difficulty in defecation. With changes in diet, faster pace of life, and social psychological factors, the prevalence of chronic constipation is on the rise. The global incidence of chronic constipation is 14%, while the prevalence of chronic constipation in adults in China is 4.0% to 10.0%. The prevalence of functional constipation in China is 6%. The high-risk groups for constipation include the elderly, women, diabetics, those taking opiates, antipsychotic drugs, or bedridden patients. Occupation, lifestyle, dietary habits, mental health, family history of constipation, and BMI are factors related to constipation. Constipation affects patients' quality of life, and some patients abuse laxatives or repeatedly seek medical treatment, increasing medical costs. The main treatments for constipation are adjusting lifestyle, medication, psychotherapy, biofeedback, and surgery. However, these methods often have side effects, and patient satisfaction is still relatively low. A new approach needs to be explored to address this clinical problem. The Disposable Gastrointestinal Vibrating Capsule System (Vibrabot capsule) (NMPA Device Approval No. 20223090282) is the world's first approved and marketed product for treating constipation through purely physical means. It can provide intermittent comfortable massages to the digestive tract, activate the intestinal neural network, awaken intestinal motility, and help alleviate constipation issues. Clinical study results show that the product is safe to use and can increase the frequency of bowel movements in patients with chronic functional constipation.However, it remains unknown whether there are differences in treatment outcomes for patients with different subtypes of functional constipation. In this study, we conducted a clinical study on patients with different subtypes of functional constipation to compare their therapeutic effects in patients with different subtypes. Patients will be divided into groups according to the results of colonic transit test, balloon push-out test, defecography and anorectal manometry. 1.
