The risk of developing postoperative chronic pain after abdominal and robot-assisted laparoscopic hysterectomy: a cross-sectional study

Objective: The two main objectives were to investigate and compare the following: (1) the development of chronic postoperative pain after robot-assisted laparoscopic hysterectomy and abdominal hysterectomy and (2) potential risk factors for developing chronic postoperative pain after hysterectomy. Design: Questionnaire-based cross-sectional study. Materials and Method: Patients having abdominal or robot-assisted laparoscopic hysterectomy procedures performed at Aalborg University Hospital, Denmark, in the period from January 2010 to December 2012. The Danish Gynecologic Cancer Database was used to identify and collect clinical data from women who had undergone total hysterectomy for endometrial cancer. Questionnaires were mailed to the included women with a response time of 5 weeks. Results: A total of 228 women received the questionnaire, and 177 (77.6%) responded. No significant difference was found in the prevalence of chronic postoperative pain between abdominal and robot-assisted laparoscopic hysterectomy, with an occurrence of 16.9% and 11.9%, respectively.
