Background and objectives: To evaluate whether the route and surgical technique by which hysterectomy is performed influence the incidence of vaginal cuff dehiscence.
Methods: We performed a retrospective analysis of total hysterectomy cases performed at Brigham and Woman's Hospital or Faulkner Hospital during 2009 through 2011.
Results: During the study period, 2382 total hysterectomies were performed; 23 of these (0.96%) were diagnosed with cuff dehiscence, and 4 women had recurrent dehiscence. Both laparoscopic (odds ratio, 23.4; P = .007) and robotic (odds ratio, 73; P = .0006) hysterectomies were associated with increased odds of cuff dehiscence in a multivariate regression analysis. The type of energy used during colpotomy, mode of closure (hand sewn, laparoscopic suturing, or suturing assisted by a device), and suture material did not differ significantly between groups; however, continuous suturing of the cuff was a protective factor (odds ratio, 0.24; P = .03). Women with dehiscence had more extensive procedures, as well as an increased incidence of additional major postoperative complications (17.4% vs 3%, P = .004).
Conclusion: The rate of cuff dehiscence in our cohort correlates with the current literature. This study suggests that the risk of dehiscence is influenced mainly by the scope and complexity of the surgical procedure. It seems that different colpotomy techniques do not influence the rate of cuff dehiscence; however, continuous suturing of the cuff may be superior to interrupted suturing.
