title: Primary torsion of the vermiform appendix and undescended cecum treated by video-assisted transumbilical appendectomy.
abstract: Torsion of the vermiform appendix is a rare cause of appendicitis that is clinically indistinguishable from the classical presentation. In this paper, we present the first report in the literature of an appendicular torsion associated with an undescended cecum. A 3-year-old male patient with persistent pain in the right hypochondrium and peritoneal irritation underwent diagnostic laparoscopy, finding necrosis of the vermiform appendix caused by torsion of its base associated with an undescended cecum located in an indurated area of the subhepatic region. A video-assisted transumbilical appendectomy was performed.
