A rare case of a severely constipated patient with rectal aganglionosis is herein reported. The patient, who had no megacolon/megarectum, underwent a STARR, i.e., stapled transanal rectal resection, for obstructed defecation, but her symptoms were not relieved. She started suffering from severe chronic proctalgia possibly due to peri-retained staples fibrosis. ...
