RESUMO
Background: The rectal prolapse is defined as the concentric protrusion of full or partial thickness of the rectum or rectosigmoid via the anus. This is an increasing clinical concern that is usually found in old female patients. Cases presentation: A 39-year-old male patient was referred due to an un-reduceable rectal projection from a week ago. The primary endeavor for reduction of the projection under sedation and after local mannitol treatment at the operation room was unsuccessful, so surgical resection and reduction were planned for the patient. Conclusion: Management of rectal prolapse has always been one of the challenges of colorectal surgery. For patients with incarcerated prolapse manual reduction under sedation is used. If the reduction is unsuccessful, surgical procedures are used.
