title: Robotic single-port transumbilical total hysterectomy: a pilot study.
abstract: OBJECTIVE
  To evaluate the feasibility of robotic single-port transumbilical total hysterectomy using a home-made surgical glove port system.
  
  
  METHODS
  We retrospectively reviewed the medical records of patients who underwent robotic single-port transumbilical total hysterectomy between January 2010 and July 2010. All surgical procedures were performed through a single 3-4-cm umbilical incision, with a multi-channel system consisting of a wound retractor, a surgical glove, and two 10/12-mm and two 8 mm trocars.
  
  
  RESULTS
  Seven patients were treated with robotic single-port transumbilical total hysterectomy. Procedures included total hysterectomy due to benign gynecological disease (n=5), extra-fascial hysterectomy due to carcinoma in situ of the cervix (n=1), and radical hysterectomy due to cervical cancer IB1 (n=1). The median total operative time was 109 minutes (range, 105 to 311 minutes), the median blood loss was 100 mL (range, 10 to 750 mL), and the median weight of the resected uteri was 200 g (range, 40 to 310 g). One benign case was converted to 3-port robotic surgery due to severe pelvic adhesions, and no post-operative complications occurred.
  
  
  CONCLUSIONS
  Robotic single-port transumbilical total hysterectomy is technically feasible in selected patients with gynecological disease. Robotics may enhance surgical skills during single-port transumbilical hysterectomy, especially in patients with gynecologic cancers.
