Abstract

Chronic Abdominal Discomfort Syndrome (CADS) is a recently proposed term that is a subclassification of Chronic Abdominal Pain, characterized by symptoms affecting clinical, diagnostic, and functional domains. Patients with CADS often have a history of abdominal surgery and experience chronic gastrointestinal symptoms such as nausea, bloating, vomiting, and dyspepsia. This review explores the underlying pathophysiology of CADS, emphasizing the role of the sympathetic and parasympathetic nervous systems in pain transmission. Various pharmacological treatments are discussed, including acid suppressants, antispasmodics, and analgesics, highlighting their effectiveness and limitations. Non-pharmacological approaches such as intrathecal pumps, nerve blocks, peripheral nerve stimulation, and spinal cord stimulation are also examined, providing insights into interventional pain management strategies. The review underscores the necessity of an individualized treatment algorithm due to the complexity of CADS and the multiple pain generators involved. Ultimately, this paper advocates for a structured approach to CADS treatment, incorporating both emerging and established therapeutic options.
