Objective: We sought to determine if past surgical history is associated with perioperative outcomes for patients undergoing hysterectomy.
Methods: A retrospective cohort study was conducted at a single, tertiary, academic health system of women who underwent hysterectomy from May 2016 - May 2017. Past surgical history (PSH) involving any abdominal or pelvic surgery, baseline demographics and perioperative outcomes were collected. For purposes of analyses, PSH was defined using three algorithms: 1) any prior abdominopelvic surgery, 2) having had abdominopelvic surgeries likely to cause adhesive disease, 3) anatomic location of prior PSH (none; pelvic; abdominal; or abdominal+pelvic). Descriptive, bivariable and multivariable analyses were performed.
Results: 1256 patients underwent hysterectomy. In adjusted analyses, PSH defined by any prior abdominopelvic surgery was associated with length of stay (LOS) (2.1 days (95%CI 1.9, 2.2) vs. 1.8 (95%CI 1.6, 2.0), (p=0.02)). PSH of procedures likely to cause adhesive disease was associated with greater estimated blood loss (EBL) (243.2 mL (95%CI 208.1, 278.3) vs. 189.0 (95%CI 1734, 204.7), (p=0.01)), longer LOS (2.5 days (95%CI 2.2, 2.8) vs. 1.9 (95%CI 1.7, 2.0), (p<0.01)), and more readmissions (OR 2.4, 95%CI 1.3, 4.5) (p<0.01). PSH defined by anatomic location revealed a trend (p=0.07) towards greater EBL in those with prior pelvic or abdominal+pelvic surgery compared to none or abdominal only, whereas LOS, readmissions and operative times did not differ. Increased total number of prior open surgeries was associated with operative time (p<0.0001), EBL (p<0.0001), hospital LOS (p<0.0001) and readmission (p=0.026).
Conclusions: Prior abdominopelvic surgery is associated with worse perioperative outcome measures in women undergoing hysterectomy.
