*2.1.4 Predisposing factors*

Intra- and post-operative bleeding generally develops in younger women or those with a more vascular pelvis who underwent a hysterectomy, especially laparoscopic hysterectomy in the presence of fibroids [6, 16].

Possible rationales for secondary hemorrhage comprise a bleeding vessel missed at the end of the procedure, effects of pneumoperitoneum, Trendelenburg position, low intraoperative pressure, wearing off the effect of vasopressin, subacute infection, postoperative analgesia, as well as bleeding disorders [2–5, 7, 9].

Other potential factors accounting for delayed postsurgical bleeding are vaginal vault infection, vault hematoma, poor surgical technique with excessive thermal injury by electrocoagulation, and early resumption of physical activity [5, 7, 9]. A large-sized uterus, high vascularity, large-sized vessels, excessive use of an energy source for the uterine artery, and culdotomy also play a role in this hemorrhagic event [5, 7, 9].
