Minimally invasive adenomyomectomy via a laparoscopic-assisted approach compared to a laparoscopic or laparotomic approach

Abstract

Objective The present study assessed the safety and benefits of laparoscopic-assisted adenomyomectomy compared to laparoscopic or laparotomic adenomyomectomy.

Materials and methods This study was a retrospective comparative study. A total of 277 patients underwent adenomyomectomy between January 2016 and January 2019 at the Department of Obstetrics and Gynaecology, Ulsan University Hospital, including 25 with laparoscopic-assisted adenomyomectomy, 82 with laparoscopic adenomyomectomy, and 170 with laparotomic adenomyomectomy. Laparoscopic-assisted adenomyomectomy consisted of a laparoscopic uterine artery procedure to reduce blood loss and a minimal incisional for laparotomic adenomyomectomy. An additional laparoscopic surgery was performed for possible pelvic pathology.

Results Data on patient demographics, surgical indications, operative times, estimated blood loss (EBL), short-term complications, and postoperative hospital stays were compared. The laparoscopic-assisted surgery (LAS) and laparotomic groups were comparable in average EBL (208.0 ± 128.8 vs. 193.6 ± 193.0 ml, p = 0.11), weight of removed mass (85.5 ± 71.7 vs. 108.2 ± 91.9 g, p = 0.39), and postoperative hospital days (HDs) (4.5 ± 1.0 vs. 4.7 ± 0.8 days, p = 0.27). These values were lower in the laparoscopic group (EBL 119.5 ± 79.6 ml, mass weight 39.3 ± 25.9 g, HD 3.6 ± 0.8 days). Additional procedures, including myomectomy and combined severe endometriosis surgery, were more frequently performed in the LAS group than the laparotomic group. The mean operating time was longer in the LAS group (179.8 ± 36.6 min) than the other groups (laparoscopy 99.9 ± 40.6 min, p < 0.00; laparotomy 133.0 ± 41.1 min, p < 0.00). The three groups did not differ significantly in transfusion rates, hemoglobin changes, or perioperative complications. However, febrile morbidity was lower in the laparoscopic group than the LAS and laparotomic groups.

Conclusion LAS adenomyomectomy allows for maximal debulking of adenomyosis via extracorporeal and intracorporeal procedures while retaining the advantages of the laparoscopic approach. Additional pelvic surgery for benign uterine and adnexal pathology may easily be performed with this approach.
