60-year-old male began to experience mucoid bloody stools in June 2001. Colonoscopy revealed multiple reddish protruding lesions mainly in the rectum and scattered from the sigmoid to the transverse colon, covered by mucous exudates. The pathological diagnosis following an endoscopic mucosal resection was cap polyposis. Although he was followed by medical treatment, the symptoms worsened. In May 2004, a laparoscopy assisted low anterior resection of the cap polyposis of the rectum was performed. After the operation, his symptoms improved and his quality of life is progressing satisfactorily. The etiology of cap polyposis is still unknown and no specific treatment has been established. Surgical treatment is one of the choices for the treatment of refractory cap polyposis that does not respond to conservative medical treatment. However, the efficacy of a surgical resection is less than 55%, so the indications for the procedure should be considered very carefully. Laparoscopic surgery is minimally invasive and is often useful in the treatment of refractory cap polyposis that does not respond medical treatment.
