Hemostatic Techniques for Myomectomy: An Evidence-Based Approach

Barbed Sutures Compared With Conventional Sutures During Laparoscopic Myomectomy: A Systematic Review and Meta-analysis

OBJECTIVE

To accumulate the currently available literature on the safety and efficacy of the use of knotless barbed sutures for the reconstruction of the uterine wall during laparoscopic myomectomy based on comparison with traditional suture studies.

DATA SOURCES

We searched PubMed/Medline, Scopus, ClinicalTrials.gov, and Google Scholar up to February 29, 2024.

METHODS OF STUDY SELECTION

Following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines and PICO criteria, we included all English-language, full-text articles that evaluated the perioperative outcomes of patients who had laparoscopic myomectomy and repair of the uterine wall defect with either barbed or traditional (extracorporeal or intracorporeal sutures).

TABULATION, INTEGRATION, AND RESULTS

The application of barbed sutures resulted in significantly reduced operative time (2,111 patients, mean difference -12.04 minutes, 95% CI, -16.94 to -7.14, P<.001). This was also reflected when suturing time was separately analyzed (437 patients, mean difference -6.04 minutes, 95% CI, -7.43 to -4.65, P<.001) The mean difference in hemoglobin levels before and after surgery was significantly lower in the barbed suture group (1,277 patients, mean difference -0.40 g/dL, 95% CI, -0.72 to -0.09, P<.01) This was also observed in case of estimated blood loss, which was found to be lower in the barbed suture group (1,823 patients, mean difference -47.22 mL, 95% CI, -78.54 to -15.90, P=.003). Finally, the barbed suture group presented lower transfusion rates (1,217 patients, odds ratio 0.43, 95% CI, 0.19-1.00, P=.05). Concerning visual analog scale (VAS) score as evaluated by the surgeons for surgical difficulty, the control group proved to be more technically challenging compared with the barbed sutures group (184 patients, mean difference -1.66 95% CI, -2.37 to -0.94, P<.001). The VAS score for pain at 24 hours postoperatively, postoperative complication rates, and length of hospital stay were similar for both groups. Regarding reproductive outcomes, there was no difference in pregnancy, live birth, and birth complication rates.

CONCLUSION

The use of barbed sutures during laparoscopic myomectomy presents many clinical benefits for the patient and the surgeon in terms of shorter operative and suturing time, less estimated blood loss, and ease of use. This pioneer technology may contribute to the expansion of laparoscopy on more complex myomectomies.

Robot-assisted laparoscopic myomectomy: Technique & brief literature review

The worldwide growth of robot-assisted laparoscopic surgery has been exponential since its FDA approval for use in gynecologic surgery in the spring of 2005. This growth has spanned the entire gamut of gynecologic procedures and pathology. One area that has leveraged the unique aspects of robotics has been its application to the conservative surgical management of uterine fibroids. This manuscript will review the surgical technique and highlight the current situation regarding the scientific literature with an evidence-based focus on the role of robot-assisted laparoscopic myomectomy (RALM) with the daVinci Surgical System (Intuitive Surgical, Sunnyvale, CA).

Minimizing blood loss in laparoscopic myomectomy with temporary occlusion of the hypogastric artery

Introduction

Uterine leiomyomas are common benign pelvic tumors. Currently, laparoscopic myomectomy (LM) is the preferred treatment option for women in the fertile age group with symptomatic myomas. The authors hypothesize that combining LM with a bilateral temporary occlusion of the hypogastric artery (TOHA) using vascular clips minimizes uterine blood flow during surgery and can significantly reduce surgery-associated blood loss.

Materials and methods

This single-center, prospective randomized study was conducted at the Department of Obstetrics and Gynecology, Municipal Emergency Clinical Hospital Timisoara, Romania. Patients aged between 18 and 49 who preferred laparoscopic myomectomy and wished to preserve fertility were included, provided they had intramural uterine leiomyomas larger than 4 cm in diameter that deformed the uterine cavity. The study analyzed data from 60 laparoscopic myomectomies performed by a single surgeon between January 2018 and December 2020. Patients were randomly assigned to either: "LM + TOHA" group (29 patients), and "LM" group (31 patients). The study's main objective was to evaluate the impact of TOHA on perioperative blood loss, expressed as mean differences in Hb (delta Hb).

Results

Delta Hb was statistically lower in the "LM + TOHA" group compared to "LM" group, with mean ± standard (min-max): 1.68 ± 0.67 (0.39-3.99) vs. 2.63 ± 1.06 (0.83-4.92) g/dL, respectively (p < 0.001). There was a statistically significant higher need for postoperative iron perfusion in the "LM" group, specifically 0 vs. 12 patients (p < 0.001), and lower postoperative anemia in "LM + TOHA" group (p < 0.001). Necessary artery clipping time was 10.62 ± 2.47 (7-15) minutes, with no significant impact on overall operative time: 110.2 ± 13.65 vs. 106.3 ± 16.48 (p = 0.21). There was no difference in the length of hospitalization or 12-month post-intervention fertility.

Discussion

Performing bilateral TOHA prior to laparoscopic myomectomy has proven to be a valuable technique in reducing surgery-associated blood loss, while minimizing complications during surgery, with no significant increase in the overall operative time.

High-intensity focussed ultrasound and hysteroscopy endo-operative system cold device procedures for treating >4cm diameter FIGO Type 2 uterine myoma and ensuring successful pregnancy

PURPOSE

Laparotomic or hysteroscopic myomectomy, and high-intensity focussed ultrasound (HIFU), can be used in the treatment of Type 2 myomas with a > 50% intramural component. Hysteroscopic electroresection may damage the remaining endometrium and complete ablation of myomas may not be realised via HIFU treatment. We report and examine the results of 1 case of HIFU treatment, accompanied with the hysteroscopy endo-operative system (HEOS) cold device procedure.

MATERIALS AND METHODS

These were used for treating a > 4cm diameter Type 2 uterine myoma and ensuring successful pregnancy. HIFU treatment of uterine myomas can achieve point-by-point ablation of lesions as far as possible without damaging the endometrium. The HEOS cold device procedure was implemented 3 months after HIFU treatment.

RESULTS

The patient got pregnant naturally in the third month after receiving treatment, with no complications during her pregnancy. The patient gave birth to a healthy male via full-term cesarean section.

CONCLUSIONS

HIFU treatment, accompanied with the HEOS cold device procedure, ensured complete myoma removal. It also preserved the integrity of the myometrium and prevented uterine perforation during surgery.

The use of sealing hemostat patch (HEMOPATCH®) in laparotomic myomectomy: a prospective case-control study

PURPOSE

Uterine myomas are the most common gynecological disease. In these cases, a myomectomy is performed traditionally laparotomically. However, alternatives have been widely used, including laparoscopic, endoscopic, and robotic surgery. During these techniques, diffuse parenchymatous bleeding remains one of the main intraoperative and postoperative complications and sometimes requires unplanned hysterectomies. Recently, hemostatic agents and sealants have been used to prevent excessive blood loss during surgical repair.

METHODS

We propose a prospective case-control study on the use of a sealing hemostat patch (HEMOPATCH^®) on uterine sutures in laparotomic myomectomy. In the period between July 2016 and April 2017, 46 patients with symptomatic uterine fibromatosis underwent surgery. They were divided into two groups of 23 patients, with different treatments in the hemostatic phase of oozing bleeding. HEMOPATCH^® is applied in group A, and spray electrocoagulation is applied in group B.

RESULTS

In group A, we achieve faster hemostasis (p < 0.05), than in group B. We report a significantly lower C-reactive protein value on the second and third days after surgery for group A compared to group B.

CONCLUSIONS

HEMOPATCH^®, during laparotomic myomectomy, is a valid alternative solution for obtaining rapid hemostasis and consequently intraoperative and postoperative bleeding. Furthermore, we suggest that a lower inflammatory peritoneal state is probably correlated with the barrier effect of the patch on the suture.

Reducing blood loss during laparoscopic myomectomy using a tourniquet loop around the lower uterine segment

OBJECTIVE

To present a simple and effective hemostatic technique using a tourniquet loop during laparoscopic myomectomy.

DESIGN

Pericervical tourniquet has been proven to be a safe and effective measure to reduce blood loss during open myomectomy. However, the use of a tourniquet in laparoscopic myomectomy has been rarely reported probably because the application is difficult and troublesome. In our technique, a prefabricated tourniquet loop, adapted from a Foley catheter, is applied around the lower segment of the uterus. It is easy to apply a tourniquet loop around the lower uterine segment during laparoscopic myomectomy. There is no need to make a window in the broad ligament to apply a pericervical tourniquet or triple tourniquets. Meanwhile, complete blockage of blood supply from the uterine artery and utero-ovarian anastomoses may ensure better hemostasis.

SETTING

A tertiary hospital.

PATIENT(S)

The patient was a 34-year-old woman with uterine leiomyoma and a desire for future fertility. She had been suffering from urinary frequency and chronic bladder pressure for the past 6 months. Magnetic resonance imaging confirmed 2 intramural masses measuring 96 mm × 91 mm and 25 mm × 13 mm at the anterior uterine wall.

INTERVENTION(S)

Institutional review board and ethics committee approval was obtained. Laparoscopic myomectomy was performed with the application of a tourniquet loop around the lower segment of the uterus (step-by-step video demonstration): homemade tourniquet loop formation using a 14-Fr latex Foley catheter; trocar placement with 2 umbilical ports (10 mm and 5 mm) and a 5-mm port at the lower-left quadrant of the abdomen; application of a tourniquet loop around the lower uterine segment; tumor enucleation and myometrial closure; removal of the tourniquet loop and a check for bleeding; contained specimen extraction via the merged umbilical incision; and inspection of the abdominal cavity and closure of the merged umbilical incision.

MAIN OUTCOME MEASURE(S)

Feasibility of using a tourniquet loop as an effective hemostatic technique in laparoscopic myomectomy.

RESULT(S)

The surgery lasted for approximately 90 minutes, and the tourniquet time was approximately half an hour. The estimated blood loss was only 20 mL. Her hemoglobin value on day 1 after the surgery was 131 g/L, the same as the preoperative level. Pathology confirmed the diagnosis of leiomyoma. The patient was discharged 2 days after the surgery with no complications. During follow-up, the patient reported that there was no discomfort and that her menses were normal. Her fallopian tubes were patent in the hysterosalpingogram. Her ovarian function, which was assessed by serum follicle-stimulating hormone concentration (5.34 mIU/mL) on day 3 of her menstrual cycle and antimüllerian hormone level (2.01ng/mL), was in the normal range. She was suggested to conceive 1 year after the procedure.

CONCLUSION(S)

Application of a tourniquet loop around the lower uterine segment is a simple and effective hemostatic technique during laparoscopic myomectomy. Randomized prospective studies are needed to determine the hemostatic effect of the laparoscopic use of a tourniquet loop and its impact on fertility and ovarian function.

Laparoscopic Triple-tourniquet Constriction: A Convenient Way for Minimizing Blood Loss during Myomectomy

STUDY OBJECTIVE

Although a pericervical tourniquet helped reduce blood loss in myomectomy [1], a technique of triple tourniquets was more influential in occluding the uterine vessel networks [2,3]. This video demonstrates the procedures of laparoscopic triple-tourniquet constriction with the number 1 suture around the uterine isthmic portion and bilateral infundibulopelvic ligaments [4] in a case of robotic myomectomy.

DESIGN

A step-by-step, narrated video demonstration.

SETTING

A university hospital.

INTERVENTIONS

Robotic myomectomy was scheduled for a patient with menorrhagia. Magnetic resonance imaging revealed 8 uterine myomas; the maximal one was 9.1 × 8.4 × 8.6 cm in dimension. Our robotic settings included 3 ports: fenestrated bipolar in the left lower quadrant, spatula or mega needle holder in the right lower quadrant, and an umbilical glove port accessible for lens and assisted instruments. A number 1 Monocryl (Ethicon, Bridgewater, NJ) was introduced from the suprapubic area extracorporeally; then, the needle penetrated through bilateral avascular zones of broad ligaments at the isthmic level and with a sliding tie made anteriorly to the uterus. The isthmic tourniquet-we also named it as the hangman's tourniquet-was tightened by manually tensioning the suture extracorporeally and pushing down the knot intracorporeally. Bilateral infundibulopelvic tourniquets were placed by using sliding ties of 1-0 Monocryl as well. With the total occlusion of uterine vessel networks, the uterus should retain only minimal blood flow. During the enucleation of uterine myomas, the tourniquet may loosen because of newly developed, unoccupied space with increasing bleeding; therefore, the tourniquet should be tightened up regularly throughout the surgery. After the repair of all the uterine wounds, we removed the 3 tourniquets.

CONCLUSION

The convenient and adjustable triple-tourniquet constriction is a safe and feasible laparoscopic technique to block the vessel networks temporally in uterine-preserving surgery.

Can the application of a temporary uterine tourniquet during an abdominal myomectomy reduce bleeding?

Objective

Uterine fibroids are common, benign uterine tumours. The three most common surgical treatment approaches for uterine fibroids are laparoscopic, robotic and abdominal myomectomies. Bleeding is a risk with all three approaches. The present study compared post-operative and pregnancy outcomes in patients with bilateral uterine artery occlusion who underwent an abdominal myomectomy, with or without a temporary uterine tourniquet.

Material and Methods

This retrospective study included patients with intra-mural fibroids (≥5 cm) who underwent an abdominal myomectomy. The patients were divided into two groups according to the use or non-use of a temporary uterine tourniquet. Post-operative and pregnancy outcomes in the tourniquet use and non-use groups were compared. The association of the number of uterine fibroids removed (≤3 vs >3) with laboratory parameters was also evaluated.

Results

A total of 84 patients were included, divided into use (n=36) and non-use (n=48) of the temporary tourniquet. There was a statistically significant difference between the groups with >3 myomas removed and with a uterine tourniquet applied and not applied in terms of reduction in hemoglobin and hematocrit, transfusion amounts, operation times and lengths of hospitalization in favour of the uterine tourniquet use group (p=0.019, p=0.023, p=0.012, p=0.044 and p=0.036, respectively). Bilateral uterine arterial occlusion using a temporary uterine tourniquet had no negative effects on pregnancy outcomes.

Conclusion

A temporary uterine tourniquet may be an effective method for reducing the amount of perioperative bleeding in patients with multiple, large-sized myomas located close to vascular structures.

Transumbilical single-site laparoscopic parallel mattress suturing prevents bleeding and chronic pelvic pain in myomectomy: a retrospective cohort study of 124 cases with intramural fibroids

Background

The most common complications of myomectomy are intraoperative hemorrhage and postoperative adhesion. The key point to overcome this problem is to improve suture quality. However, to date, there is still no consensus on the optimal method of uterine repair. In this study, we explored the effectiveness and feasibility of single-site laparoscopic parallel mattress sutures to reduce intraoperative bleeding and postoperative adhesion.

Methods

A retrospective cohort analysis was performed, according to the STROBE guidelines, on 124 patients with intramural fibroids admitted between May 2020 and April 2021. The cases were divided into two groups based on the description of the uterine incision suture in the surgical records, including 68 cases in the parallel mattress suture (PMS) group and 56 cases in the simple continuous suture (SCS) group. Operation-related indicators, bleeding indicators, surgical complications, scar reduction index 1 month after surgery, and the incidence of chronic pelvic pain 6 months after the surgery were observed. Independent sample t-tests and Mann–Whitney U tests were performed for the measurement data, and Pearson Chi-square tests were performed for count data. Statistical significance was set at P < 0.05.

Results

There was no significant difference in the baseline characteristics between the two groups. All operations were performed under transumbilical single-site laparoscopy without conversion. Compared to the SCS group, the PMS group had earlier postoperative anal exhaust (14.3 ± 6.7 h vs. 19.2 ± 9.6 h, P = 0.002), fewer postoperative hemoglobin drops (7.6 ± 3.7 g/L vs. 11.6 ± 4.3 g/L, P = 0.000), smaller uterine scars (3.7 ± 1.9 cm vs. 5.2 ± 1.8 cm, P = 0.000), and a larger uterine scar reduction index (50.2% vs. 31.0%, P = 0.000) one month after surgery and less chronic pelvic pain 6 months after surgery (2.9% vs. 12.5%, P = 0.016). No difference was found in auxiliary trocar usage, transfusion rate, operation time, hospital stay, or perioperative complications between the two groups.

Conclusion

Seromuscular parallel mattress sutures during myomectomy can prevent pinhole errhysis of the uterine incision, achieve complete serosal and aesthetic incisions, and reduce postoperative chronic pelvic pain. It is effective and feasible to complete a parallel mattress suture during myomectomy via single-site laparoscopy. Further prospective studies are required to determine its efficacy as well as pregnancy outcomes.

Factors influencing intraoperative blood loss and hemoglobin drop during laparoscopic myomectomy: a tailored approach is possible?

A retrospective study was conducted on patients subjected to laparoscopic myomectomy at our institution from January 2017 to December 2018 to identify predictive factors of blood loss. Two multiple regression models were run to predict intraoperative blood loss and haemoglobin drop. Predictors of an increased intraoperative blood loss and haemoglobin drop were the presence of three-four fibroids at ultrasound (+47 ml, p = .01; +0.58 g/dl, p = .05) and increased operative time (r = 0.57, p = .01; r = 0.01, p < .01), while predictors of a reduced intraoperative blood loss and haemoglobin drop were epinephrine injection (-50 ml, p < .01; -0.42 g/dl, p < .01), FIGO7 (-87 ml, p < .01; -0.85, p = .01), and FIGO6 (-35 ml, p < .01; -0.44, p = .02) fibroids at the ultrasound. Preoperative ultrasound evaluation is crucial in identifying patients at higher risk for blood loss, which could benefit from optimising haemoglobin values. The injection of diluted epinephrine could be proposed in selected high-risk patients. In the clinical practice, a tailored approach based on fibroids' ultrasonographic characteristics should be implemented to optimise preoperative Hb values and evaluate the use of diluted epinephrine in selected cases, reducing blood loss and the potential related complications.Impact statementWhat is already known on this subject? Laparoscopic myomectomy is the conservative surgical treatment of choice for symptomatic uterine fibroids. Still, it could represent a challenging procedure even for an experienced surgeon, with the risk of excessive blood loss, need of transfusions, prolonged operative time, and prolonged hospital stay. The knowledge of the predictive factors of blood loss is essential for patient preparation and surgical planning to reduce intraoperative and postoperative complications.What do the results of this study add? The results of the present study focus on the importance of presurgical evaluation to identify predictive factors of intraoperative blood loss and Hb drop such as the number of fibroids and the FIGO classification (at preoperative ultrasound), as well as intraoperative factors like operative time and the intramyometrial injection of diluted epinephrine.What are the implications of these findings for clinical practice and/or further research? A tailored approach based on the ultrasonographic characteristics of fibroids should be implemented to optimise preoperative haemoblobin levels.

Intracervical intracapsular myomectomy using loop ligation: a proposed technique

Performing laparoscopic myomectomy for an intracervical myoma, especially a single giant myoma, is challenging. Only skilled surgeons attempt this operation. Surgeons frequently encounter cases of massive intraoperative bleeding, difficulty suturing the cervical incision, risk of injuring the neighbouring tissues, haematoma formation and conversion to laparotomy or hysterectomy. We previously developed a the technique of loop ligation of the pseudocapsule and have been using it to treat sizeable intracervical myomas laparoscopically. Its advantages include less blood loss, lower risk of injuries to the neighbouring tissues, maintenance of the cervical canal and sparing of the pseudocapsule. This technique is safe and feasible, and facilitates fertility.

How to minimize bleeding in laparoscopic myomectomy

PURPOSE OF REVIEW

Laparoscopic myomectomy is a common surgical procedure for symptomatic myomas. However, bleeding control during surgery may pose a challenge. Therefore, the aim of this study was to review recent evidence regarding interventions to control bleeding during laparoscopic myomectomy.

RECENT FINDINGS

The use of vasopressin resulted in less blood loss compared to placebo. Barbed sutures reduced blood loss compared to conventional sutures. Intravenous infusion of tranexamic acid (TXA) in the intraoperative period of large myomectomies showed no significant difference compared to placebo. Uterine artery occlusion (UAO) and emergency uterine artery embolization were reported to be feasible and may reduce and treat bleeding before conversion to laparotomy.

SUMMARY

Several methods can control bleeding during laparoscopic myomectomy. Vasopressin and barbed sutures resulted in decreased blood loss, and TXA did not have an impact on bleeding control. The use of UAO and emergency embolization techniques can contribute to the control of bleeding; however, further studies are needed to prove the efficacy of these and other agents.

Single-port access (SPA) laparoscopic myomectomy with uterine artery ligation via a retroperitoneal approach is feasible in women with large uterine leiomyoma

OBJECTIVE

Uterine artery ligation (UAL) at the time of myomectomy has shown to decrease blood loss during the operation. However, little is known about the efficacy and feasibility of UAL during single-port access (SPA) myomectomy. The present study was performed to investigate the clinical benefits of UAL in SPA myomectomy and to provide details of the surgical techniques.

MATERIALS AND METHODS

A retrospective and comparative review on the surgical outcomes of the patients who underwent SPA myomectomy with UAL and those who underwent SPA myomectomy without UAL was conducted. UAL was performed at its origin from the internal iliac artery via a retroperitoneal approach.

RESULTS

A total of 56 women who received SPA myomectomy were reviewed (24 patients received SPA myomectomy with UAL while 32 patients received SPA myomectomy only). The median weight of total resected leiomyomas was heavier for the patients who received UAL than those who did not receive UAL [210.0 g (range: 171.5-335.0 g) vs. 119.0 g (62.5-265.0 g), p = 0.023]. However, no differences in total operative time, estimated blood loss, perioperative hemoglobin changes, use of postoperative analgesics and postoperative complications between the two groups were seen.

CONCLUSION

Obtaining similar surgical outcomes between the patients who received UAL with larger leiomyomas and those who did not receive UAL with smaller leiomyomas suggests that UAL is a feasible surgical approach to reduce blood loss during SPA myomectomy. Detailed descriptions of the surgical techniques are provided in the present report.

The Number of Myomas Is the Most Important Risk Factor for Blood Loss and Total Operation Time in Robotic Myomectomy: Analysis of 242 Cases

To identify factors affecting blood loss and operation time (OT) during robotic myomectomy (RM), we reviewed a total of 448 patients who underwent RM at Seoul Asan Hospital between 1 January 2019, and 28 February 2021, at Seoul Asan Hospital. To avoid variations in surgical proficiency, only 242 patients managed by two surgeons who each performed >80 RM procedures during the study period were included in this study. All cases of RM were performed with a reduced port technique. We obtained the following data from each patient's medical chart: age, gravidity, parity, body mass index, and history of previous abdominal surgery including cesarean section. We also collected information on the maximal diameter and type of myomas, number and weight of removed myomas, concomitant surgery, total OT from skin incision to closure, estimated blood loss (EBL), and blood transfusion. Data on preoperative use of gonadotropin-releasing hormone agonists (GnRHas) and perioperative use of hemostatic agents (tranexamic acid or vasopressin) were also collected. Data on the length of hospital stay, postoperative fever within 48 h, and any complications related to RM were also obtained. The primary endpoint in this study was the identification of factors affecting EBL and the secondary endpoint was the identification of factors affecting the total OT during multiport RM. Univariate and multivariate analyses were used to identify the factors affecting EBL and OT during multiport RM. The medians of the maximal diameter and weight of the removed myomas were 9.00 (interquartile range [IQR], 7.00 to 10.00) cm and 249.75 (IQR, 142.88 to 401.00) g, respectively. The median number of myomas was two (IQR, one to four), ranging from 1 to 34. Of the cases, 155 had low EBL and 87 had high EBL. Most myomas were of the intramural type (n = 179). The odds of EBL > 320 mL increased by 251% (odds ratio [OR], 2.51; 95% confidence interval [CI], 1.16-5.42) for five to nine myomas and by 647% (OR, 6.47; 95% CI, 1.87-22.33) for ≥10 myomas. The odds of subserosal-type myomas decreased by 67% compared with intramural-type myomas (OR, 0.33; 95% CI, 0.14-0.80). History of abdominal surgery other than cesarean section was positively correlated with EBL. The weight of the removed myomas and a history of previous cesarean section were not correlated with the EBL. Conclusion: The number of myomas (5-9 and ≥10), maximal myoma diameter, and history of abdominal surgery other than cesarean section affect the EBL in RM.

A Clinically Applicable Prediction Model for the Risk of Transfusion in Women Undergoing Myomectomy

STUDY OBJECTIVE

We sought to identify the variables independently associated with intra/postoperative blood transfusion at the time of myomectomy. We further hoped to develop an accurate prediction model using preoperative variables to categorize an individual's risk of blood transfusion during myomectomy.

DESIGN

Case-control study.

SETTING

Not applicable to this study, which used the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database.

PATIENTS

Women who underwent an open/abdominal or laparoscopic (robotic or conventional) myomectomy between 2014 and 2017 at participating ACS-NSQIP sites.

INTERVENTION

The primary dependent variable was occurrence of intra/postoperative bleeding requiring blood transfusion. Patient demographics, clinical characteristics, preoperative comorbidities, intraoperative variables, and additional 30-day postoperative outcomes were compared at the bivariable level. For the prediction-model development, only variables that can be reasonably known before surgery were included. Variables associated with intra/postoperative bleeding were entered into 2 separate multivariable logistic regression models. Validation of our prediction model was performed internally using 250 bootstrapped iterations of 50% subsamples drawn from the overall population of myomectomy cases from the ACS-NSQIP database.

MEASUREMENTS AND MAIN RESULTS

We identified 6387 myomectomies performed during the defined study period. The most common race in our population was black/African American (45.7%), and most of the patients (57.5%) received an open/abdominal route of myomectomy. A total of 623 patients who underwent myomectomy (9.8%) experienced intraoperative/postoperative bleeding with a need for blood transfusion. At the bivariable level, we identified several variables independently associated with the need for blood transfusion at the time of myomectomy. In using only those variables that can be reasonably known before surgery to develop our prediction model, additional multivariable logistic regression elucidated black race, need for preoperative blood transfusion, planned abdominal/open route of surgery, and preoperative hematocrit value as independently associated with blood transfusion.

CONCLUSION

We identified a number of perioperative variables associated with intraoperative or postoperative bleeding requiring blood transfusion at the time of myomectomy. We subsequently created a model that accurately predicts individual bleeding risk from myomectomy, using variables that are reasonably apparent preoperatively. Making this prediction model clinically available to gynecologic surgeons will serve to improve the care of women undergoing myomectomy.

The Emerging Role of Robotic Single-site Approach for Myomectomy: A Systematic Review of the Literature

Objective. To review the existing studies on single-site robotic myomectomy and test the safety and feasibility of this innovative minimally invasive technique. Data Sources. PubMed, Scopus, Google Scholar (from their inception to October 2019), as well as Clinicaltrials.gov databases up to April 2020. Methods of Study Selection. Clinical trials (prospective or retrospective) that reported the outcomes of single-site robotic myomectomy, with a sample of at least 20 patients were considered eligible for the review. Results. The present review was performed in accordance with the guidelines for Systematic Reviews and Meta-Analyses (PRISMA). Four (4) studies met the inclusion criteria, and a total of 267 patients were included with a mean age from 37.1 to 39.1 years and BMI from 21.6 to 29.4 kg/m2. The mean operative time ranged from 131.4 to 154.2 min, the mean docking time from 5.1 to 5.45 min, and the mean blood loss from 57.9 to 182.62 ml. No intraoperative complications were observed, and a conversion rate of 3.8% was reported by a sole study. The overall postoperative complication rate was estimated at 2.2%, and the mean hospital stay ranged from 0.57 to 4.7 days. No significant differences were detected when single-site robotic myomectomy was compared to the multiport technique concerning operative time, blood loss, and total complication rate. Conclusion. Our findings support the safety of single-site robotic myomectomy and its equivalency with the multiport technique on the most studied outcomes. Further studies are needed to conclude on the optimal minimally invasive technique for myomectomy.

Misoprostol vs vasopressin as a single hemostatic agent in laparoscopic myomectomy: Comparable, or just better than nothing?

AIM

Laparoscopic myomectomy may be associated with considerable blood loss, especially in patients in whom no specific hemostatic measures are used. We conducted this retrospective comparative study to investigate whether misoprosol is an effective and safe alternative to vasopressin when used as single hemostatic agent in laparoscopic myomectomy.

METHODS

Two hundred cases undergoing laparoscopic myomectomy (-ies), were included. Of these, 50 pre-treated with vaginal misoprostol 400mcg 1 h before surgery (group 1), were compared with two historic consecutive groups: 100 patients treated with intraoperative intra-myometrial injection of dilute vasopressin (20 IU/100 mL normal saline) (group 2), and 50 treated without use of any hemostatic agent (group3).

RESULTS

Mean procedure length did not differ significantly between the three groups (127.9 vs 100.6 vs 130.8 min). Mean estimated blood loss (EBL) was 179.7 ± 200.0 mL in group 1, compared with 147.8 ± 171.8 mL in group 2 (P = 0.793) and 321.8 ± 246.0 mL in group 3, respectively (P < 0.001). EBL was lower in group 2 in most of the study's subgroups of patients stratified according to size and number of fibroids compared with group 1, with the exception of patients with ≥4 fibroids, and ≥7 cm in size. In these subgroups, misoprostol appeared more effective. Neither agent was associated with serious adverse events.

CONCLUSION

Vaginal misoprostol can be effective in reducing blood loss during laparoscopic myomectomy. Although rates of EBL are, in general, higher compared with those obtained with vasopressin, they are significantly reduced compared with those observed when no hemostatic agent is used. In extended procedures, vaginal misoprostol, due to its prolonged uterotonic action, may be associated with reduced blood loss compared with vasopressin.

Laparoscopic-assisted myomectomy with uterine artery occlusion at a freestanding ambulatory surgery center: a case series

Background

Non-hysteroscopic myomectomy is infrequently performed in a freestanding ambulatory setting, in part due to risks of intraoperative hemorrhage. There are also concerns about increased surgical risks for morbidly obese patients in this setting. The purpose of this study is to report the surgical outcomes of a series of laparoscopic-assisted myomectomy (LAM) cases at a freestanding ambulatory surgery center (ASC), including a comparative analysis of outcomes in morbidly obese patients (BMI > 40 kg/m²).

Methods

A retrospective comparative analysis was performed of 969 women, age 18 years or older, non-pregnant, who underwent LAM by one of two high volume, laparoscopic gynecologic surgical specialists at a freestanding ambulatory surgery center serving the Washington, DC area, between October 2013 and February 2019. Reversible occlusion was performed laparoscopically by placing a latex-based rubber catheter as a tourniquet around the isthmus of the uterus, causing a temporary occlusion of the bilateral uterine arteries. Permanent occlusion was performed laparoscopically via retroperitoneal dissection and uterine artery ligation at the origin of the anterior branch of the internal iliac artery. Minilaparotomy was performed for specimen removal in all cases. No power morcellation was used. Postoperative complications were graded using the Clavien-Dindo Classification system. Outcomes were compared across BMI categories using Pearson Chi-Square.

Results

Average myoma weight and size were 422.7 g and 8.3 cm, respectively. Average estimated blood loss (EBL) was 192.1 mL; intraoperative and grade 3 postoperative complication rates were 1.4% and 1.6%, respectively. While EBL was significantly higher in obese and morbidly obese patients, this difference was not clinically meaningful, with no significant difference in blood transfusion rates. There were no statistically significant intraoperative or postoperative complication rates across BMI categories. There was a low rate of hospital transfers (0.7%) for all patients.

Conclusion

Laparoscopic-assisted myomectomy can be performed safely in a freestanding ambulatory surgery setting, including morbidly obese patients. This is especially important in the age of COVID-19, as elective surgeries have been postponed due to the 2020 pandemic, which may lead to a dramatic and permanent shift of outpatient surgery from the hospital to the ASC setting.

Myomectomy associated blood transfusion risk and morbidity after surgery

OBJECTIVE

To evaluate blood transfusion risks and the associated 30-day postoperative morbidity after myomectomy.

DESIGN

Retrospective cohort study.

SETTING

Not applicable.

PATIENT(S)

Women who underwent myomectomies for symptomatic uterine fibroids (N = 3,407).

INTERVENTION(S)

Blood transfusion during or within 72 hours after myomectomy.

MAIN OUTCOME MEASURE(S)

The primary outcomes were rate of blood transfusion with myomectomy and risk factors associated with receiving a transfusion. The secondary outcome was 30-day morbidity after myomectomy.

RESULT(S)

The overall rate of blood transfusion was 10% (hysteroscopy, 6.7%; laparoscopy, 2.7%; open/abdominal procedures, 16.4%). Independent risk factors for transfusion included as follows: black race (adjusted odds ratio [aOR] 2.27, 95% confidence interval [CI] 1.62-3.17) and other race (aOR 1.77, 95% CI 1.20-2.63) compared with white race; preoperative hematocrit <30% compared to ≥30% (aOR 6.41, 95% CI 4.45-9.23); preoperative blood transfusion (aOR 2.81, 95% CI 1.46-5.40); high fibroid burden (aOR 1.91, 95% CI 1.45-2.51); prolonged surgical time (fourth quartile vs. first quartile aOR 11.55, 95% CI 7.05-18.93); and open/abdominal approach (open/abdominal vs. laparoscopic aOR 9.06, 95% CI 6.10-13.47). Even after adjusting for confounders, women who required blood transfusions had an approximately threefold increased risk for experiencing a major postoperative complication (aOR 2.69, 95% CI 1.58-4.57).

CONCLUSION(S)

Analysis of a large multicenter database suggests that the overall risk of blood transfusion with myomectomy is 10% and is associated with an increased 30-day postoperative morbidity. Preoperative screening of women at high risk for transfusion is prudent as perioperative transfusion itself leads to increased major postoperative complications.

Topical hemostatic and tissue-sealing agents in gynecologic surgery

PURPOSE OF REVIEW

To review current topical hemostatic agent use and how it pertains to gynecologic surgery.

RECENT FINDINGS

Recent literature suggests some benefit of topical hemostatic agents (THA). THAs confer reduced bleeding and shorter operating room time in women undergoing hysterectomy for cancer and in abdominal myomectomy. THA use in women undergoing ovarian cystectomy is associated with a decreased reduction in ovarian reserve. Potential complications of THA use include abscess formation, small bowel obstruction, inflammation, allergic reaction, and transmission of blood-borne pathogens. Evidence for use of THA in benign minimally invasive gynecologic surgery (MIGS) procedures is lacking.

SUMMARY

Although evidence exists for the efficacy of THA in reducing blood loss and operating times across surgical subspecialties, specific, appropriate, and efficacious use of THAs in gynecologic surgery remains ill-defined. Knowledge of their mechanisms of action and potential complications should enable surgeons to optimize desired effects and minimize harm.

Tranexamic acid in gynecologic surgery

Objective: To review the mechanism of action, pharmacology, dosing, and complications of tranexamic acid (TXA) and consolidate current evidence for TXA in gynecologic surgery.Methods: A literature search of PubMed, Ovid (MEDLINE), Google Scholar, and Elsevier was performed, in addition to a targeted search of cited references involving TXA and gynecologic surgery. Preference was given to systematic reviews and randomized control trials (RCTs).Results: TXA reversibly binds to plasminogen, preventing clot degradation. RCTs on hysterectomy, myomectomy, cervical conisation, hysteroscopy, and surgery for cervical and ovarian cancer were identified, as were case reports on TXA use for ectopic pregnancy. During hysterectomy, TXA reduces blood loss (two RCTs, n = 432, mean difference -66.0 mL and 180 mL), blood transfusion (1 RCT, n = 100, 12% vs. 42%, p < .00001). For myomectomy, a systematic review and meta-analysis showed a statistically significant decrease in blood loss with TXA (two RCTs, mean difference -213.1 mL, 95% CI: -242.4 mL to -183.7 mL). Following cervical conisation, TXA decreased the risk of delayed hemorrhage (four RCTs, RR 0.23, 95% CI: 0.11-0.50). A single RCT for cervical and ovarian cancer surgery demonstrated a decrease mean blood loss of 120 mL-135 mL and 210 mL, respectively, and fewer blood transfusions for the latter (OR 0.44, upper 95% CI: 0.97, p = .02). Less robust data suggest a possible benefit from TXA during hysteroscopy and surgery for ectopic pregnancies. Most commonly, 1 g of intravenous TXA is given intraoperatively.Conclusion: TXA is a safe adjunct that can be considered in a variety of gynecologic surgeries to decrease blood loss and risk of blood transfusion.

Laparoscopic-assisted myomectomy: Surgery center versus outpatient hospital

Aim

To compare the safety protocols and operative outcomes of women undergoing laparoscopic‐assisted myomectomy (LAM) by the same surgeons at a freestanding ambulatory surgery center (ASC) versus a hospital outpatient setting.

Methods

Retrospective chart review of all women ≥18 years old with symptomatic leiomyoma, who underwent LAM with uterine artery occlusion or ligation for blood loss control, at a freestanding ASC between 2013 and 2017, and an outpatient hospital setting between 2011 and 2013, both serving the metropolitan Washington, DC area. The procedures were performed by two minimally invasive gynecologic surgical specialists from a single practice. The safety protocols of each setting were reviewed to identify similarities and differences.

Results

A total of 816 LAM cases were analyzed (ASC = 588, hospital = 228). The rate of complications was comparable across settings, as was the average myoma weight (ASC = 396.2 g; hospital = 461.5 g; P = 0.064). Operative time was significantly shorter at the ASC: 68 min (95% CI 66–70) versus 80 min at hospital (95% CI 76–84), P < 0.0001. Ambulatory surgery center and hospital protocols differed in limits of preoperative hemoglobin (minimum 9.0 g/dL, 7.5 g/dL respectively), lower nurse/patient ratio in PACU, and were similar in intraoperative surgical safety standards.

Conclusion

Laparoscopic‐assisted myomectomy can be performed safely and effectively by skilled surgeons at a freestanding ASC, even in patients with morbid obesity or large leiomyoma.

Esmolol Infusion Reduces Blood Loss and Opiate Consumption during Fertility Preserving Myomectomy

Objectives

The objective of this study is to evaluate the effect of esmolol-induced hypotensive anesthesia (EIHA) on intra-operative (IO) bleeding during open myomectomy.

Patients and Methods

Eighty-eight women were randomly divided into the study group received EIHA without uterine tourniquet and control group who received normotensive anesthesia with uterine tourniquet. EIHA was provided as priming dose of esmolol (0.5 mg.kg^-1) before the induction of anesthesia and esmolol infusion (0.05-0.3 mg.kg^-1.min^-1) to maintain mean arterial pressure at 60-70 mmHg that was stopped on completion of myomectomy. Fentanyl was used as IO analgesia (loading dose: 1.0 μg.kg^-1 then infusion of 0.2-0.4 μg.kg^-1.h^-1). All patients received 6% hydroxyethyl starch (HES; initially, 3 mL.kg^-1 over 5-10 minutes and supplemental doses according to requirements) and Lactated Ringer's solution (LR; 5 mL.kg^-1.h^-1). Trigger for blood transfusion was hemoglobin concentration (HBC) <7 g.dL^-1. Study outcomes included the extent of postoperative (PO) HBC deficit in relation to preoperative HBC, frequency of tourniquet application for the study patients, and total fentanyl consumption.

Results

EIHA significantly reduced blood pressure measures since laryngoscopy and tracheal intubation till the end of surgery in the study group compared to control group. Eight study patients (18.9%) required tourniquet application for control of bleeding; however, amount of IO blood loss; total field visibility score and PO HBC deficit were non significantly lower in the study group. EIHA allowed significant reduction of the IO amount of LR and additional amounts of HES infusions. Study patients group consumed significantly lower IO fentanyl doses with significantly longer duration till the 1^st PO request and the number of additional fentanyl, and lower numeric rating scale scores in study group compared to controls.

Conclusion

Open myomectomy under EIHA is feasible and safe and allows fertility-sparing with minimal risk of blood transfusion. The applied procedure of EIHA allowed blunting of pressor reflexes secondary to LIT, surgical stresses and extubation, and allowed reduction of IO and PO opioid doses.

Comparison between the vascular control technique and conventional technique for reducing operative blood loss during robot-assisted myomectomy

BACKGROUND

This retrospective study aimed to compare the surgical outcomes and morbidity of the vascular control technique in robotic myomectomy with the conventional technique.

METHODS

Thirty-two consecutive patients who underwent robotic myomectomy using laparoscopic vascular clamps in 2017 to 2019 (the practice change cohort) were retrospectively comparted with 32 case-matched consecutive patients who underwent the conventional robotic myomectomy (the historical cohort). The primary outcome was the operative blood loss and hemoglobin change.

RESULTS

The two cohorts had similar baseline characteristics. The mean operative blood loss and hemoglobin changes were lower in the practice change cohort than in the historical cohort (P < .001 and P = .005, respectively). Other postoperative outcomes were similar between two cohorts.

CONCLUSION

The vascular control technique in robotic myomectomy appears to be effective and safe in the management of selective patients with symptomatic myomas.

Laparoscopic management of uncommon benign uterine tumors: a systematic review

The objective of the study was to review the reported cases of uncommon benign uterine tumors managed by laparoscopy. Medline database was searched using predefined search terms linked to atypical leiomyomas, leiomyoma variants, laparoscopy and morcellation. Quality of articles was assessed using Joanna Briggs Institute (JBI) critical appraisal tool. Due to heterogeneity in reporting characteristics of the patients, radiological findings, macroscopic findings, histological characteristics and follow-up, we performed a narrative synthesis. We included 109 cases of leiomyoma variants managed by laparoscopy. This stands for an incidence of 2.5% out of all the included laparoscopic management of leiomyomas. These cases were approached as classic leiomyoma. Only after the final histological results that their uncommon aspect was diagnosed. Intra-operatively, the management was similar to that of leiomyoma, with either myomectomy or hysterectomy performed depending on each individual case. Follow-up of these cases was variable: one case (0.9%) recurred as peritoneal sarcoma after 5 years of follow-up. It is important for the gynecologist, radiologist and pathologist to be aware about leiomyoma variants trying to diagnose them preoperatively. Strict follow-up of these cases is mandatory, because of the risk of recurrence and the very low but possible risk of future sarcomas.

Successful Pregnancies in Women with Diffuse Uterine Leiomyomatosis after Hysteroscopic Management Using the Hysteroscopy Endo Operative System

STUDY OBJECTIVE

To evaluate the feasibility, effectiveness, and reproductive outcome of hysteroscopic management using the Hysteroscopy Endo Operative system (HEOS) in patients with diffuse uterine leiomyomatosis (DUL).

DESIGN

Retrospective study (Canadian Task Force classification III).

SETTING

Beijing Tiantan Hospital, Capital Medical University, Beijing, China.

PATIENTS

Eight women of reproductive age suffering from menorrhagia and anemia or infertility diagnosed with DUL by ultrasonography and hysteroscopy.

INTERVENTIONS

Hysteroscopic surgery using cold graspers combined with electric loop by the HEOS was performed to excise submucous myomas (including types 0, I, and II), leaving other intramural myomas in place. The fenestration method is used in electrical hysteroscopic myomectomy. Postoperative endometrial repair and synechiae, menstrual improvement, conception, and pregnancy were recorded.

MEASUREMENTS AND MAIN RESULTS

Two patients underwent a single hysteroscopic myomectomy, whereas 6 patients underwent 2 to 3 myomectomies. No complications were observed. The mean follow-up period was 39.13 ± 17.01 months (range, 21-67). The endometrium recovered 2 to 3 months after the initial surgery, and 100% improvement in menstruation was observed. Two patients had mild synechia after the first hysteroscopic surgery. Seven patients conceived spontaneously (postoperative pregnancy rate, 87.5%), 6 of whom had a full-term pregnancy. One patient suffered a miscarriage in the second trimester (live birth rate, 75%).

CONCLUSION

Hysteroscopic surgery using cold graspers combined with electric loop by the HEOS is a feasible and effective for treatment of DUL because it preserves the uterus and yields favorable reproductive outcomes. The cold surgery and fenestration method minimizes electrical and thermal damage to the endometrium surrounding the myoma, consequently reducing surgical risks.

Surgical Planning and Counseling in Adolescence: A Case Report of a 16-Year-Old with an Aborting Pelvic Mass

Laparoscopic-Assisted Myomectomy with Bilateral Uterine Artery Occlusion/Ligation

STUDY OBJECTIVE

Conventional laparoscopic myomectomy (CLM) and robotic-assisted myomectomy (RAM) are limited in the number and size of myomas that can be removed, whereas abdominal myomectomy (AM) is associated with increased complications and morbidity. Here we evaluated the surgical outcomes of these myomectomy techniques compared with those of laparoscopic-assisted myomectomy (LAM), a hybrid approach that combines laparoscopy and minilaparotomy with bilateral uterine artery occlusion or ligation to control blood loss.

DESIGN

Retrospective chart review (Canadian Task Force classification II-1).

SETTING

Suburban community hospital.

PATIENTS

Women age ≥18 years with nonmalignant indications.

INTERVENTION

A total of 1313 consecutive CLMs, RAMs, AMs, and LAMs performed between January 2011 and December 2013.

MEASUREMENTS AND MAIN RESULTS

Our review included 163 CLMs (12%), 156 RAMs (12%), 686 AMs (52%), and 308 LAMs (23%). Although the average number, size, and total weight of leiomyomas removed were comparable in the LAM and AM groups (9.1, 8.13 cm, and 391 g, respectively, vs 9.0, 7.5 cm, and 424 g; p < .0001), the number and weight of myomas were significantly greater in those 2 groups compared with the CLM and RAM groups (2.9 and 217 g, respectively, and 2.9 and 269 g; p < .0001). The intraoperative complication rate was highest in the RAM group, and the postoperative complication rate was highest in the AM group, both of which were approximately 3 times greater than the rates in the LAM group. There was no statistically significant difference in postoperative complication rates between the CLM and LAM groups.

CONCLUSION

LAM with uterine artery occlusion/ligation is a viable approach for removing large tumor loads while minimizing blood loss and precluding the need for power morcellation.

Vasopressin during Laparoscopic Myomectomy: Does It Really Extend Its Limits?

STUDY OBJECTIVE

Τo investigate whether the use of vasopressin played an important role in the safe expansion of the indications of laparoscopic myomectomy in our practice.

DESIGN

A retrospective comparison of prospectively collected data (Canadian Task Force classification II2).

SETTING

A gynecologic endoscopy unit in a tertiary university hospital.

PATIENTS

One hundred fifty patients undergoing laparoscopic myomectomy; 50 were treated without the use of any vasoconstrictive agent (group 1), and 100 were treated with intraoperative intramyometrial injection of dilute vasopressin (20 IU/100 mL normal saline) (group 2).

INTERVENTIONS

Laparoscopic myomectomy.

MEASUREMENTS AND MAIN RESULTS

We compared the 2 groups in terms of size, number, and type of myomas; estimated blood loss (EBL); procedure length; transfusion rates; laparoconversion rates; and rates of complications. Two cases in group 1 (4%) were laparoconverted versus none (0%) in group 2. Overall, the mean EBL was 321.8 ± 246.0 mL in group 1 compared with 147.8 ± 171.8 mL in group 2, respectively (p <.001). Additionally, EBL was significantly lower in the vasopressin group in all of the study's subgroups of patients stratified according to the size and number of myomas. Procedure length did not differ significantly between the 2 groups (130.8 ± 49.5 vs 115.6 ± 49.4 minutes, p = .078). The risk factors for prolongation of the procedure included size and number of myomas independently of vasopressin. The rates of hypercapnea and subcutaneous emphysema were higher in group 1. The risk factors for hypercapnea and subcutaneous emphysema included the size and intramural position of the largest myoma. Vasopressin was not associated with serious cardiovascular adverse events.

CONCLUSIONS

Vasopressin is effective in reducing blood loss during laparoscopic myomectomy. Although experienced surgeons may achieve comparable operation times without vasopressin, even in the most challenging cases, blood loss may still be considerable. The occurrence of hypercapnea is higher in untreated cases and may contribute to laparoconversion.

The menstrual cycle and blood loss during laparoscopic myomectomy

INTRODUCTION

Operative morbidity of laparoscopic myomectomy largely relates to the potential for intraoperative blood loss. We sought to determine whether blood loss varies according to the menstrual cycle.

MATERIAL AND METHODS

A retrospective study of 268 women who underwent a laparoscopic myomectomy from 2007 to 2012. Patients were categorized into five menstrual groups: follicular phase, luteal phase, oligomenorrheic or amenorrheic on hormonal therapy, postmenopausal or other. Patient and procedure characteristics were compared for the follicular phase group, luteal phase group, and hormonal therapy group. The estimated blood loss was compared across the five groups using a regression model.

RESULTS

A total of 268 women underwent a laparoscopic myomectomy: 108 (40.3%) were in the follicular phase, 92 (34.3%) were in the luteal phase, 44 (16.4%) were on hormonal therapy, nine (3.4%) were postmenopausal, and 15 (5.6%) could not be classified. Baseline patient characteristics were similar between the groups with the exception of endometriosis. Geometric mean estimated blood loss was 91.9 mL in the follicular phase group, 108.7 mL in the luteal phase group, 114.1 mL in the hormonal therapy group, and 39.8 mL in the postmenopausal group. There was no significant difference in the geometric mean estimated blood loss when comparing the follilcuar phase, luteal phase, and hormonal phase groups (p = 0.41). Upon adjusted multivariable analysis of all five menstrual groups, there was also no difference in estimated blood loss.

CONCLUSIONS

Intraoperative blood loss during laparoscopic myomectomy does not vary significantly with the phase of the menstrual cycle.

Resectoscopic Surgery for Polyps and Myomas: A Review of the Literature

Resectoscopic surgery is routinely performed to remove endometrial polyps and uterine myomas. A search of Medline, PubMed, and the Cochrane Library was conducted through November 2016 for studies written in English, regardless of sample size or study type. The studies were then filtered by selecting those evaluating resectoscopic surgery. An analysis of peer-reviewed, published literature was performed to examine the clinical application of this treatment modality on patients requiring polypectomy and myomectomy. Different surgical techniques were also compared: hysteroscopy with scissors, forceps, or a cold loop; resectoscopy with radiofrequency energy; and mechanical resection. The literature finds that operative time during resectoscopic surgery is significantly longer than with mechanical resection. Resectoscopic myomectomy, however, may be necessary for removal of larger or more deeply embedded myomas. Ultimately, both techniques result in symptom resolution and a low recurrence rate.

Role of robotic surgery in treating fibroids and benign uterine mass

Fibroid uterus can be managed medically, surgically, or through non-extirpative procedures, depending on the clinical situation. Myomectomy may be beneficial, especially to those desiring to preserve the uterus and/or fertility, with outcomes comparable to those of hysterectomy, with a laparoscopic approach being favored when feasible. For definitive therapy, hysterectomy can be pursued where the surgical approach should be individualized. Comparison of robotic-assisted laparoscopic approach shows that the robotic approach may be favored for cases with higher complexity and multiple fibroids in myomectomy; however, no clear advantage is seen with hysterectomy at this time, necessitating further research in the area of robotics for hysterectomy in benign uterine mass treatment to justify the cost.

Predictors of postoperative hemoglobin drop after laparoscopic myomectomy

Introduction

Laparoscopic myomectomy (LM) can be associated with significant bleeding.

Aim

To identify factors influencing the postoperative hemoglobin (Hb) drop after LM.

Material and methods

This is a retrospective, single-center study. We evaluated data of 150 consecutive patients undergoing LM due to intramural myomas between 2010 and 2015.

Results

The median age of the patients was 37 (23–53) years. The mean diameter of the largest myoma was 5.7 ±2.3 (1.5–12) cm. The mean surgical time was 83 ±38 (35–299) min. The median number of sutures was 3 (1–11). The mean postoperative Hb drop was 1.6 ±1.2 (0–6) g/dl, and the mean estimated blood loss was 261 ±159 (50–1700) ml. In the univariate analysis, the postoperative Hb drop correlated with the duration of surgery (p < 0.001), diameter of the largest myoma (p < 0.001), cumulative myoma weight (p < 0.001), and number of sutures (p < 0.001), but not with patients’ age or number of intramural myomas. In the multivariable analysis, the surgical time (β = 0.395, p < 0.001), diameter of the largest myoma (β = 0.292, p = 0.03) and preoperative Hb concentration (β = 0.299, p < 0.001) predicted the postoperative Hb change.

Conclusions

Surgical time and dominant myoma diameter are independent predictors of the postoperative Hb drop after LM.
