How common is a cuff dehiscence after a total hysterectomy?

Depends... It depends on how the hysterectomy was done. In one large series the dehiscense rate was as follows: Total Laparoscopic hyst = 0.64%; Abdominal Hyst = 0.2%; and Vaginal Hyst = .13%. You can see that the incidence is low for all types of hysterecomy but is highest after a Total Laparoscopic Hysterectomy. The Da Vinci Robot is often used to perform total laparoscopic hysterectomy. Best wishes.
