Comparison of Postoperative Complications Between Laparoscopic Myomectomy and Total Laparoscopic Hysterectomy.

STUDY

OBJECTIVE

To compare postoperative complications of laparoscopic myomectomy (LM) with total laparoscopic hysterectomy (TLH). A secondary outcome examined whether complications differ by age.

DESIGN

A retrospective cohort study.

SETTING

A multicenter academic healthcare system.

PATIENTS: Individuals > 18 years old undergoing LM from 2011 to 2021 or TLH for benign indications from 2020 to 2021.

INTERVENTIONS: LM or TLH.

MEASUREMENTS AND MAIN

RESULTS

There were 1178 patients in the LM group and 1304 in the TLH group. Patients who underwent LM were younger, more often premenopausal, nonsmokers, with lower body mass index, lower preoperative hemoglobin, larger uterine size, and lower American Society of Anesthesiologists class. LM had longer operative times (154.1 ± 74.5 vs 145.9 ± 70.5 min, p <.0001), higher use of intraoperative hemostatic agents (25% vs 9.1%, p <.0001), and higher estimated blood loss (222.7 ± 313.0 vs 87.4 ± 145.9 mL, p <.0001) than TLH. Postoperatively, LM was associated with fewer surgical site infections (3.1% vs 5.8%, p <.0001), readmissions within 30 days (2.0% vs 5.6%, p <.0001), or emergency department visits within 90 days (10.9% vs 14.4%, p = .008). LM were more likely to be admitted 24 hours postoperatively (5.9% vs 3.4%, p = .0023) or receive a blood transfusion within 30 days (4.0% vs 1.0%, p <.0001). Variables associated with increased risk of postoperative complications were tobacco use, American Society of Anesthesiologists class > 3, preoperative anemia, estimated blood loss ≥ 150 mL, and specimen weight > 250 g. Logistic regression demonstrated that operative time ≥185 minutes was most strongly associated with 24-hour admission postoperatively (odds ratio [OR] = 12.95; 95% confidence interval [CI], 3.71-45.27). In individuals ≤ 37 years of age, the LM group was less likely than the TLH group to experience surgical site infection (OR, 0.30; 95% CI, 0.14-0.62) or present to the emergency department (OR, 0.40; 95% CI, 0.26-0.63).

CONCLUSION

In this large cohort of patients, both LM and TLH had low rates of postoperative complications, but the complications differed for each approach. In appropriate surgical candidates, either approach may be offered based upon patients' goals.
