RESUMEN
STUDY OBJECTIVE: To compare outcomes following umbilical minilaparotomy and suprapubic minilaparotomy for tissue extraction. DESIGN CLASSIFICATION: Retrospective cohort study (Canadian Task Force classification II-2). SETTING: Two large academic medical centers. PATIENTS: Women who underwent a minilaparotomy for tissue extraction following a laparoscopic hysterectomy or myomectomy between 2014 and 2016. INTERVENTIONS: Umbilical or suprapubic minilaparotomy for tissue extraction. MEASUREMENTS AND MAIN RESULTS: A total of 374 women underwent laparoscopic hysterectomy or myomectomy with minilaparotomy, including 289 (77.3%) with an umbilical minilaparotomy and 85 (22.7%) with a suprapubic minilaparotomy. The 2 groups were similar in terms of age, body mass index, parity, surgical history, procedure type, surgical approach, and surgical indication. The size of the minilaparotomy incision and the specimen weight were significantly smaller in the umbilical minilaparotomy group (mean, 3.3 ± 0.8 cm vs 4.2 ± 0.6 cm [p < .001] and 472.6 ± 357.1 g vs 683.0 ± 475.7 g [p < .001], respectively). Two women in the suprapubic minilaparotomy group sustained a bladder injury during creation of the incision. There were no other complications related to the minilaparotomy in either group. Postoperative outcomes related to the minilaparotomy incision were compiled using the medical record and a follow-up survey. Of the 374 women in this cohort, 163 responded to a detailed survey about their minilaparotomy incision (response rate, 43.5%). With regard to the minilaparotomy, 52.7% of women reported incisional symptoms; 25.9% had increased pain at the incision, 8.3% had an incisional infection, and 2.7% reported an incisional hernia. There was no significant between-group difference in incisional outcomes; however nearly 3 times as many women in the umbilical minilaparotomy group reported concerns about incisional hernia (3.1% vs 1.2%; p = .833). These findings were maintained in a multivariable logistic regression analysis. No patient or procedure characteristics were significantly associated with the development of hernia. CONCLUSION: There were no significant difference in incisional symptoms, pain, or infection following umbilical minilaparotomy vs a suprapubic minilaparotomy for tissue extraction. Although not statistically significant, the rate of incisional hernia was higher at the umbilical site compared with the suprapubic site.

BACKGROUND: Safe tissue removal is a challenge for minimally invasive procedures such as myomectomy, supracervical hysterectomy, or total hysterectomy of a large uterine specimen. There is concern regarding disruption or dissemination of tissue during this process, which may be of particular significance in cases of undetected malignancy. Contained tissue extraction techniques have been developed in an effort to mitigate morcellation-related risks. OBJECTIVE: The objective of the study was to quantify perioperative outcomes of contained tissue extraction using power morcellation, specifically evaluating parameters of tissue or fluid leakage from within the containment system. STUDY DESIGN: This was a study including a multicenter prospective cohort of adult women who underwent minimally invasive hysterectomy or myomectomy using a contained power morcellation technique. Blue dye was applied to the tissue specimen prior to removal to help identify cases of fluid or tissue leakage from within the containment system. RESULTS: A total of 76 patients successfully underwent the contained power morcellation protocol. Mean time for the contained morcellation procedure was 30.2 minutes (±22.4). The mean hysterectomy specimen weight was 480.1 g (±359.1), and mean myomectomy specimen weight was 239.1 g (±229.7). The vast majority of patients (73.7%) were discharged home the same day of surgery. Final pathological diagnosis was benign in all cases. Spillage of dye or tissue was noted in 7 cases (9.2%), although containment bags were intact in each of these instances. CONCLUSION: Findings are consistent with prior work demonstrating the feasibility of contained tissue extraction; however, further refinement of this technique is warranted.
