Transvaginal contained tissue extraction after laparoscopic myomectomy: a cohort study

Surgical Outcomes and Complications of Myomectomy: A Prospective Cohort Study

STUDY OBJECTIVE

To investigate postoperative surgical and non-surgical complications that occur within 30 days following myomectomy procedures, whether laparoscopic or via open surgery.

DESIGN

Prospective cohort study SETTING: Del Ponte Women's and Children's Hospital, Varese, Italy.

PATIENTS

Women undergoing myomectomy either with laparoscopic or open surgery from July 2020 to June 2023 INTERVENTIONS: Data of consecutive patients who underwent abdominal myomectomy procedures, either via laparoscopy or open abdominal surgery were collected. The study examined patient characteristics, size and location of fibroids, surgical data, and complications. Univariate and multivariable analyses were employed to identify factors contributing to postoperative Clavien-Dindo grade ≥ II complications.

MEASUREMENTS AND MAIN RESULTS

Overall 383 patients were included in the study. The univariate analysis showed intramural fibroid type (p = .0009), large fibroid size (p = .03), and extended operative times (p = .05) were associated with postoperative complications. Open surgical approach (p <.001) and uterine cavity opening (p = .02) also contributed to complications. Postoperative anemia emerged as the most prevalent complication. In the multivariable analysis, the open surgical approach emerged as the only independent factor associated with an increased risk of grade ≥ II complications (odds ratio 7.37; p <.0001).

CONCLUSION

In this study we found an increased likelihood of complications in case of open myomectomy. While the presence of potential selection bias may have impacted this finding, it could provide valuable insights for clinicians and surgical teams in the strategic planning of myomectomy procedures.

In-bag extraction of tissue through an incision in the posterior vaginal wall in laparoscopic myomectomy: a large retrospective study

BACKGROUND

Our purpose was to describe the outcomes of transvaginal in-bag tissue extraction tissue through an incision in the posterior vaginal wall the middle part incision of posterior vagina in laparoscopic myomectomy.

METHODS

This was a retrospective study of patients who received laparoscopic myomectomy and in-bag tissue extraction through an incision in the posterior vaginal wall between January 2016 and December 2022. Patient characteristics, intra- and post-operative complications, and outcomes were collected and analyzed.

RESULTS

A total of 511women were included in the analysis. The mean largest myoma diameter was 8.44 ± 3.56 cm; mean specimen weight was 789.23 ± 276.97 g; mean operative time was 129.01 ± 53.13minutes; and mean blood loss was 175.99 ± 210.96 mL. Within 30-days of surgery, no fever, infection, or vaginal bleeding was noted in any patient, and the vaginal incisions of all patients had healed well. There were no incisional hernias, pelvic infections, and vaginal adhesions noted at follow-up 3 months after the operation. There were 37 cases of vaginal delivery of the patients after surgery, and there were no lacerations of the posterior wall vaginal incision.

CONCLUSIONS

Transvaginal in-bag extraction though an incision in the posterior vaginal wall is feasible and safe for removing tissue after laparoscopic myomectomy.

Laparoscopic subtotal hysterectomy followed by in-bag transvaginal corpus uteri morcellation and extraction: A case series

OBJECTIVES

Laparoscopic subtotal hysterectomy (LSH) is a possible treatment for patients with benign uterine disease. Once the hysterectomy has been completed, morcellation and extraction of the corpus uteri is a crucial step of the procedure. We here present a case series to evaluate the feasibility of the in-bag transvaginal specimen retrieval following LSH.

STUDY DESIGN

We report a case series of consecutive patients who underwent LSH followed by in-bag transvaginal specimen retrieval. LSH was accomplished in a standard fashion. Once the uterus was detached from the cervix, a 2 cm posterior colpotomy was performed laparoscopically with a monopolar hook under direct view to insert a specimen retrieval bag into the abdomen. The corpus uteri was placed into the bag and transvaginal contained manual morcellation was performed. The colpotomy was then sutured transvaginally. Baseline patients' characteristics and surgical data were collected. Postoperative complications, same-hospital readmissions, and reoperations were registered if occurred within 30 days from surgery.

RESULTS

Patients' median age and BMI were 45,5 and 22,7, respectively. Median operative time was 71.5 min (range 34-143) and uterus weight ranged from 60 g to 470 g (median 210 g). The estimated blood loss was 100 mL (median) and no blood transfusion was required. No conversions to open surgery, nor intraoperative complications occurred. Median hospital stay was 2 days (1-3) and no postoperative complications within 30 days from surgery were recorded.

CONCLUSIONS

LSH followed by in-bag transvaginal specimen extraction is a promising technique and might be considered a reliable and safe option to further reduce the invasiveness of the procedure.

Outcomes of In-bag Transvaginal Extraction in a Series of 692 Laparoscopic Myomectomies: Results from a Large Retrospective Analysis

STUDY OBJECTIVE

Transvaginal extraction is a feasible method to remove surgical specimen. In this study, we aim to report our experience with in-bag transvaginal specimen retrieval after laparoscopic myomectomy over the past 15 years.

DESIGN

Single-center retrospective analysis.

SETTING

Academic hospital.

PATIENTS

Women who underwent laparoscopic myomectomy from January 2005 to April 2021.

INTERVENTION

Posterior colpotomy and in-bag transvaginal extraction of the surgical specimen.

MEASUREMENTS AND MAIN RESULTS

We collected and analyzed data about patients' characteristics, main indication for surgery, and intra- and postoperative (within 30 days) complications.

RESULTS

A total of 692 women underwent transvaginal specimen retrieval after laparoscopic myomectomy (mean largest myoma diameter: 6.64 ± 2.21 cm; mean specimen weight: 177 ± 140 g; mean operative time: 84.1 ± 37.1 minutes; mean blood loss: 195 ± 191 mL). Within 30-days, we reported the following colpotomy-related complications: a total of 4 cases (0.6%) of vaginal bleeding, 3 of which resolved spontaneously (1 case required readmission with new colporrhaphy under general anesthesia), and 2 cases (0.3%) of vaginal pain, with no underlying cause identified on physical examination and pelvic ultrasound. Specimen weight was positively correlated with longer operative time, intraoperative blood loss, and length of hospital stay.

CONCLUSION

Posterior colpotomy and in-bag transvaginal extraction can be considered a feasible option for retrieval of surgical specimens after laparoscopic myomectomy.

Total surgical time in laparoscopic supracervical hysterectomy with laparoscopic in-bag-morcellation compared to laparoscopic supracervical hysterectomy with uncontained morcellation

Background

A possible solution to the problem of cell dissemination through laparoscopic uncontained morcellation during laparoscopic supracervical hysterectomy (LASH) is the use of laparoscopic in-bag morcellation. One criticism regarding the use of in-bag morcellation is the additional surgical time associated with this procedure.

Objectives

In this retrospective study we compared the total surgical time in LASH with laparoscopic in-bag morcellation (107 cases from 2016-2018) and LASH with uncontained morcellation (47 cases from 2015-2017).

Materials and Methods

All surgeries were performed in the same department of minimally invasive gynaecological surgery by a total of three experienced surgeons for the indication of bleeding disorder and / or dysmenorrhea.

Main outcome measures

We measured and compared total surgical time, surgical outcome, blood loss and complications in LASH with in-bag morcellation and with uncontained morcellation.

Results

Total surgical time in both procedures do not show a significant difference. Considering the learning curve in laparoscopic bag use, the total surgical time in LASH with laparoscopic in-bag morcellation is shorter than total surgical time in LASH with uncontained morcellation. Laparoscopic in-bag morcellation consumes time for bag use and handling, but saves time as it eliminates the need for meticulous sampling of lost tissue fragments and the complex lavage of the peritoneal cavity after morcellation. There is no difference between both groups in terms of blood loss, complications and surgical results.

Conclusion/What is new?

We conclude that LASH with in-bag morcellation is not related to additional surgical time when compared to LASH with uncontained morcellation.

Novel technique of extracorporeal intrauterine morcellation after total laparoscopic hysterectomy: Three emblematic case reports

BACKGROUND

In the presence of a large uterus, total laparoscopic hysterectomy (TLH), always requires morcellation to allow removal of the tissues from the abdominal cavity. However, uncontained morcellation has been scrutinized because of the possible spread of occult leiomyosarcoma. Therefore, in-bag extracorporeal morcellation has been developed. However, tissue containment and extraction are extremely challenging, especially when considering the increasing uterine size to be removed through minimally invasive surgery.

CASE SUMMARY

Herein, we describe a novel technique for extracorporeal intrauterine morcellation using the uterus outermost layer as a bag to achieve tissue extraction of very large uteri with suspected occult leiomyosarcoma after TLH. The study enrolled patients who were planned for TLH for large uteri (weight > 500 g). TLH was performed following the procedure reported in our previous studies. The novel technique has been described step-by-step in a video, which representatively describes the preoperative imaging and morcellation procedure of three very large uteri weighing 1500 g, 1700 g, and 3700 g, respectively. The procedures were performed without any complications. The patients had an uneventful postoperative course, and in all cases, the pathology was benign leiomyoma.

CONCLUSION

Extracorporeal intrauterine morcellation using the uterus outmost layer as a bag was found to be a feasible technique that allows a careful diagnosis and safe removal of suspected occult malignancies. The technique herein presented may be adopted in surgical practice, by adding it to the other available techniques of contained morcellation. It may represent a valid and feasible alternative, especially useful in cases of very large uteri exceeding the capacity of specimen retrieval bags.

The Medical Device Applied to Uterine Fibroids Morcellation: Analysis of Critical Biological Issues and Drawbacks from A Medical-Legal Prospective

Following the FDA safety communication of 2014 increasing attention has been to the treatment of uterine fibroids, due to the suspicion of a potential leiomyosarcoma (ULM). FDA banned the use of power morcellation in the US, since this technique is likely to spread malignant cells from an unsuspected ULM. We criticized the medical legal consequences of this banning among gynecologists and patients, focusing on the drawbacks of biology and surgery. The authors analyzed literature data on one side, on the incidence, diagnosis and treatment of leiomyoma and ULM, and the other side, on the power morcellations and related critical issues, trying to highlight their main controversial aspects and to outline the possible impact on patients and on medical responsibility. The alternative methods to power morcellation are more invasive surgical solutions (as mini laparotomy or culdotomy), which inevitably involve associated risks with the surgical procedure as such and always request the containing bags. Although the in-bag morcellation is a promising technique, currently the used devices are largely off-label. This highlights the surgical risk, in case of complications, of suffering for malpractice claims both for not having used a containment system, favoring the spread of the neoplasm, and for its off-label use. Since the diagnosis of ULM is by histology after surgery, the fear of legal consequences or medical malpractice for unknown ULM power morcellation, should be targeted to analyze, in terms of cost/benefit ratio, the surgical priority. It should focus on the prevention of the risk of having a rare and statistically limited ULM or on the surgical-related complications, often linked to a slowdown minimally invasive surgery, or on the use of the authorized in-bag morcellations.

Safety of Minimally Invasive Tissue Extraction in Myoma Management: A Systematic Review

OBJECTIVE

This review seeks to establish the incidence of adverse outcomes associated with minimally invasive tissue extraction at the time of surgical procedures for myomas.

DATA SOURCES

Articles published in the following databases without date restrictions: PubMed, EMBASE, Web of Science, Cochrane Database of Systematic Reviews and Trials. Search was conducted on March 25, 2020.

METHODS OF STUDY SELECTION

Included studies evaluated minimally invasive surgical procedures for uterine myomas involving morcellation. This review did not consider studies of nonuterine tissue morcellation, studies involving uterine procedures other than hysterectomy or myomectomy, studies involving morcellation of known malignancies, nor studies concerning hysteroscopic myomectomy. A total of 695 studies were reviewed, with 185 studies included for analysis.

TABULATION, INTEGRATION, AND RESULTS

The following variables were extracted: patient demographics, study type, morcellation technique, and adverse outcome category. Adverse outcomes included prolonged operative time, morcellation time, blood loss, direct injury from a morcellator, dissemination of tissue (benign or malignant), and disruption of the pathologic specimen.

CONCLUSION

Complications related to morcellation are rare; however, there is a great need for higher quality studies to evaluate associated adverse outcomes.

Intraperitoneal ultrasound scan by culdotomy before laparoscopic ovarian resection: a novel approach

We describe a novel technique of intraperitoneal ultrasound scan by culdotomy before laparoscopic ovarian resection. To preserve the ovarian parenchyma in a recurrence of serous borderline ovarian tumor, a usual transvaginal ultrasound probe was introduced into the abdominal cavity, covered by a sterile bag, through posterior colpotomy. The pelvis was filled with saline solution and the ultrasound imaging was performed allowing the identification of tumor margins. After precise cystectomy, the tumor was delivered within the endo bag, through the posterior colpotomy. This new approach may be a feasible, effective and cheap technique to guide laparoscopic surgery for complex and/or small ovarian tumors.

Unexpected uterine smooth muscle tumor of uncertain malignant potential and sarcoma: A single center cohort study in South Korea

OBJECTIVE

To evaluate the risk of encountering unexpected uterine smooth muscle tumors of uncertain malignant potential (STUMPs) or sarcomas during surgical treatment of mesenchymal tumors of the uterus using morcellation.

MATERIAL AND METHODS

Data were collected retrospectively from subjects who were pathologically diagnosed with uterine leiomyoma or its variants, STUMP or other premalignant mesenchymal tumors of uterus, or sarcoma during surgical treatment between July 2014 and June 2017.

RESULTS

A total of 3785 women were investigated; 2824 laparoscopic procedures (74.6%) were performed, and an electronic power morcellator was used in 1636 patients (43.2%). Sixteen women (0.42%) were diagnosed with STUMP and 14 (0.37%) were diagnosed with uterine sarcoma. The incidence rate of unexpected STUMP or uterine sarcoma was 0.61% (23 of 3785 women); unexpected STUMP in 13 (0.34%), and unexpected sarcoma was in 10 (0.26%). Moreover, the unexpected leiomyosarcoma rate was 0.08% (3 in 3785). The rate of unintended morcellation of STUMPs was relatively high at 0.26% (10 in 3785), however, that for uterine sarcomas was 0.05% (2 in 3785).

CONCLUSION

The risks of unintended morcellation were very low for sarcomas and STUMPs, although the risk of the latter was approximately 5-fold that of the former. To reduce the unintended dissemination of tumors, patients suspected of having malignancies should be provided adequate information regarding their treatment options as well as their associated risks. Meanwhile, improved preoperative screening methods for STUMP and sarcoma should be established.

Culdotomy in laparoscopic myomectomy and its limits

OBJECTIVE

To examine the results and limits of culdotomy method for removal of myoma from the abdomen while preserving its integrity in laparoscopic myomectomy. To determine if this is a good option for tissue extraction.

DESIGN

Retrospective analysis of data collected prospectively.

SETTING

A gynecology and obstetrics training and research hospital.

PATIENTS

A total of 102 patients who underwent laparoscopic myomectomy with culdotomy for tissue extraction.

RESULTS

A total of 102 patients underwent laparoscopic myomectomy between September 2017 and April 2019, and tissues were taken from the abdomen by culdotomy. The mean myoma diameter was 7.7 ± 2.4 cm (4-15 cm) and the mean weight was 161 ± 120 g (20-602 g). The mean duration of surgery was 95 ± 41 min (36-214 min). All myomas were extracted with preservation of their integrity, except in 2 patients. In 87 patients, the myoma was less than 10 cm, and all myomas in this group could be easily extracted from the vagina. The myoma was between 11 and 13 cm in 13 patients. Of these, 8 were extracted without difficulty, 5 could barely be extracted, and superficial vaginal lacerations occurred in 4 of these patients. Due to the inability to extract myomas intact in 2 patients (14 and 15 cm), vaginal mechanical morcellation was performed. In terms of vaginal births, 34 patients (33.3 %) had never had vaginal births, and 68 patients (66.7 %) had a history of vaginal birth. The largest myoma extracted from a woman who had not given birth was 12 cm (345 g). The largest myoma extracted from a woman who had given birth was 13 cm (490 g). None had major complications. No signs of infection were detected on the 7th and 30th postoperative days, and no operative dyspareunia was detected at 6-month follow-up.

CONCLUSION

In the present study, it was seen that myomas up to 13 cm (490 g) in multiparous and 12 cm (350 g) in nulliparous could be removed from the culdotomy while maintaining their integrity. Culdotomy is a safe, inexpensive and effective method for myoma extraction.

Rethinking the Issue of Power Morcellation of Uterine Fibroids: Is Morcellation the Real Problem or Is this Another Symptom of Disparity in Healthcare Provision?

Power morcellation remains one of the most significant developments in minimal access surgery over the past decade, allowing many more patients to benefit from the least invasive surgical route. However, its use is not without controversy, particularly with regards to the risks of an undiagnosed leiomyosarcoma. Increased media and, in particular, on-going social media coverage since events in 2014 have only served to intensify the debate, culminating in the Food and Drug Administration essentially 'banning' its use in the USA. Practice however continues to vary and this technique remains widely used in Europe and in particular the UK. The aim of this article was to review the development of power morcellation in gynaecology and the underlying risks, including that of undiagnosed leiomyosarcoma, as well as appraise the evolving literature on patient awareness and informed consent and the wider implications of morcellation restriction.

Tissue Extraction in Gynecologic Surgery: Past, Present, and Future

Fibroid tissue extraction during hysterectomy and myomectomy has become increasingly controversial. A wave of research has tried to clarify difficult questions around the prevalence of occult malignancies, the effect of morcellation on cancer outcomes, proper informed consent, and surgical options for tissue extraction. This review examines the history of these controversies and discusses tissue extraction techniques and continued areas of debate in the field.

Transabdominal versus transvaginal specimen extraction in mini-laparoscopic surgery

AIM

The objective of this study was to present our experiences of tissue extraction via the transvaginal (TV) route after a mini-laparoscopic gynecological surgery and compare them with our transabdominal (TA) specimen extraction experiences.

METHODS

This prospective randomized controlled study was conducted in a tertiary care center between July 2014 and February 2016. Fifty-eight women who were undergoing mini-laparoscopy for adnexal mass removal were randomized into two groups according to the surgical specimen removal by the TV route (n = 28) or the TA route (n = 30). The main outcome measures were the postoperative incisional pain, cosmetic outcomes and overall satisfaction rate. The secondary outcome measures were additional blood loss, additional operation duration and the need for morcellation.

RESULTS

The TV group had significantly lower visual analog scale scores than the TA group at 6 and 24 h postoperatively. The morcellation needs were lower in the TV group than in the TA group. Three months after the surgery, the participants scored a higher rate of overall satisfaction in the cosmetic outcomes in the TV group than in the TA group.

CONCLUSION

Tissue extraction through a posterior colpotomy after mini-laparoscopic surgery may be a feasible technique for improving cosmetic results, decreasing postoperative pain and decreasing the need for morcellation when compared to TA specimen retrieval.

Surgical treatment of large adnexal masses: a retrospective analysis of 330 consecutive cases

Introduction: In the present study, perioperative outcomes of laparoscopy (LPS) were compared to open surgery (OS) for the treatment of large adnexal masses (AM).Material and methods: Retrospective observational cohort study. Data of consecutive patients who underwent ovarian cystectomy or salpingo-oophorectomy for large AM (diameter ≥10 cm) at a referral minimally invasive gynecologic center were analyzed. Propensity score match (PSM) analysis was used to minimize covariate imbalances between the two groups.Results: Overall 330 patients, 285 (86.4%) LPSs and 45 (13.6%) OSs were included. PSM showed LPS (vs. OS) to be associated with less intraoperative blood loss (mL: 131.1 ± 52.6 vs. 545.5 ± 101.2; p = .007), shorter operative time (min: 84.8 ± 77.9 vs. 123.7 ± 70.1; p < .001), but higher rate of spillage (54.5% vs. 12.1%; p < .001). Among the LPS group, a positive correlation between AM size and both conversion to open surgery and need for mini-laparotomy was found (p < .05).Conclusions: An accurate patient selection, a dedicated workup, and an appropriate counselling are mandatory before LPS for large AM. The increased risks of intraoperative spillage associated with the minimally invasive approach should be acknowledged.

Minimally Invasive Myomectomy: An Overview on the Surgical Approaches and a Comparison with Mini-Laparotomy

Uterine fibroids (UFs) are the most common benign solid tumors of the female genital tract manageable by surgical of pharmacological approach. When the medical management is ineffective or surgery is primarily requested, several surgical approaches can be used. Among these, minimally invasive surgery might be preferred. Myomectomy is the standard surgical treatment when fertility sparing is claimed. It can be performed via laparoscopy, robotic surgery and hysteroscopy and the choice depend on UFs features and surgeon's skill. Alongside these minimally invasive options, mini-laparotomy has been proposed as a less invasive surgical approach comparable to the well-established minimally invasive options. The aim of this review is to describe the most recent advances in minimally invasive techniques to perform myomectomy, comparing them with mini-laparotomy approach.
