Functional Constipation with Sigmoid Redundancy and Prolapse Recti in a Young Adult: A Complex Case Report and Surgical Treatment Approach

Introduction: Constipation is a common health issue, with most causes considered functional.Some cases of constipation are complicated by a redundant sigmoid colon and rectal prolapse, which exacerbate symptoms and management.A redundant sigmoid colon is often asymptomatic but can lead to many complications.The combination of these three conditions is rarely reported in medical literature; however, understanding how to select effective therapies and reduce the risk of long-term complications is crucial.Case report: We report a case of an 18-year-old male with chief complaints of difficulty defecating for an extended period, accompanied by abdominal pain.The patient has experienced hard stools and often expresses feelings of incomplete evacuation along with abdominal discomfort.He has had similar complaints since the second grade in elementary school, which necessitated medication to facilitate bowel movements.Additionally, he underwent hemorrhoid surgery a year ago due to bleeding and a persistent anal protruding mass.His mother denied any history of Hirschsprung disease.Upon physical and radiological examination, a diagnosis of redundant sigmoid with rectal prolapse was made.The patient was scheduled for laparoscopic resection and mesh rectopexy.Conclusion: Chronic constipation in young adults require evaluation, especially if there are indications of anatomical complications such as redundant sigmoid colon and rectal prolapse.Operative management and multidisciplinary care can improve quality of life and prevent long-term complications.Operative management in this case is expected to improve functional capacity in young adults.
