These mechanisms could occur simultaneously in variable proportions and could explain why several patients develop recurrence of pain even after being treated by all the currently available modalities, such as antioxidants, endoscopic therapies and surgery.\n\nIn the studies by the investigators over the past 2 years, they observed that persistent pain in these patients was associated with varying grades of depression and poor quality of life. This was accompanied by alteration in the metabolites in the brain (anterior cingulate cortex, prefrontal cortex, hippocampus, and basal ganglia) as evidenced in magnetic resonance spectroscopy (MRS) of the brain. These areas in the brain are responsible for pain modulation, long-term pain memory and emotional responses to pain.\n\nWhen the investigators counselled these patients and explained their disease and possible outcomes based on their own clinical course, imaging and treatment response (personalized education\u002Fcounselling), they reported significant improvement in depression, quality of life parameters and, interestingly, also in pain. Further, there were changes in the metabolite parameters in the brain on MRS after personalized counselling\u002Feducation that was more similar to that of healthy controls.\n\nThis led to our hypothesis that better understanding of the disease and its outcomes by the patients could improve their coping capabilities and increase their pain thresholds. This could augment the pain responses of these patients to the other therapeutic modalities.\n\nWe will conduct this single blinded, placebo controlled, randomized controlled trial on patients with documented CP of over 3 years duration, who had at least 3 episodes of abdominal pain of over the past 3 months.",[96,31,97],"Chronic Pancreatitis","Depression, Anxiety",[99,67,100,101,102,103,104,105],"chronic pancreatitis","depression","anxiety","quality of life","metabolome","magnetic resonance spectroscopy","quantitative sensory testing","NOT_YET_RECRUITING","2025-07-27",{"date":109,"type":36},"2025-07-30",{"date":111,"type":21},"2025-08-01",{"date":113,"type":21},"2026-12-31",{"name":115,"class":42},"Asian Institute of Gastroenterology, India",{"id":117,"slug":118,"hasResults":11,"nctId":119,"briefTitle":120,"officialTitle":120,"acronym":4,"eligibilityCriteria":121,"healthyVolunteers":11,"sex":16,"minAge":17,"maxAge":18,"enrollmentInfo":122,"targetDuration":4,"studyType":22,"phases":124,"briefSummary":125,"conditions":126,"keywords":4,"overallStatus":32,"whyStopped":4,"lastUpdateSubmitDate":132,"lastUpdatePostDateStruct":133,"startDateStruct":135,"completionDateStruct":137,"leadSponsor":139,"locationsCount":43},"100584093","ultrasound-guided-multilevel-erectorspinae-plane-block-versus-thoracic-epidural-analgesia-for-prevention-of-post-mastectomy-pain-syndrome-for-breast-cancer-patients-100584093","NCT06884852","Ultrasound-guided Multilevel Erectorspinae Plane Block Versus Thoracic Epidural Analgesia for Prevention of Post Mastectomy Pain Syndrome for Breast Cancer Patients","Inclusion Criteria:\n\n* Female patients age ≥ 18 years and ≤ 65 Years.\n* Type of surgery;
