[Influence of postoperative pelvic floor function on different surgical procedures of hysterectomy].

To compare the influence of postoperative pelvic floor function after different surgical procedures of hysterectomy. A total of 260 patients who underwent hysterectomy in Renmin hospital of Wuhan University from January 2012 to January 2014 were enrolled in the study, and divided into 5 groups by different surgical procedures, which were total abdominal hysterectomy (A-TH; 46 cases), total laparoscopic hysterectomy (L-TH; 59 cases), total vaginal hysterectomy (V-TH; 42 cases), abdominal intrafascial hysterectomy (A-CISH; 78 cases), laparoscopic intrafascial hysterectomy (L-CISH; 35 cases). Pelvic examination, pelvic organ prolapse quantitation (POP-Q), test of pelvic muscle strength, pelvic floor distress inventory-short form 20 (PFDI-20) and the female sexual function index (FSFI) questionnaire were measured after 6 months and 12 months. The differences of pelvic organ prolapse incidence after 6 months, A-TH and A-CISH [7% (3/46) versus 3% (2/78)], A-TH and L-CISH [7% (3/46) versus 3% (1/35)] were statistically significance (all <0.05).POP-Q grade after 6 months between A-TH and A-CISH was statistically different in degree (<0.05). The differences of incidence of abnormal pelvic floor muscle fatigue after 6 months of A-TH and A-CISH [59% (27/46) versus 29% (23/78)], A-TH and L-CISH [59% (27/46) versus 26% (9/35)] were statistically significant (all <0.05), after 12 months the difference of L-TH and A-CISH [61% (36/59) versus 29%(23/78)] was statistically different (<0.05). The differences of incidence of abnormal pelvic floor muscle strength after 6 months of L-TH and A-CISH [53% (31/59) verus 24% (19/78)], V-TH and A-CISH [60% (25/42) verus 24% (19/78)], V-TH and L-CISH [60% (25/42) verus 23% (8/35)] were statistically significant (all <0.05); after 12 months the difference of V-TH and A-CISH [57% (24/42) versus 26%(20/78)] was statistically significant (<0.05). Stress urinary incontinence, abnormal bowel movements after 6 months and 12 months were no significant difference between groups (all >0.05), PFDI-20 total score was not statistically significant (>0.05). FSFI total score after 6 months and 12 months in A-TH and A-CISH, L-TH and A-CISH, A-CISH and L-CISH were statistically significant (all <0.05). The influences of different surgical procedures to pelvic floor function are no statistical difference; as to the surgical resection of hysterectomy, intrafascia hysterectomy compared with extrafascia hysterectomy, the former is more helpful to the protection of the structure and function of the pelvic floor.
