Laparoscopic administration of bupivacaine at the uterosacral ligaments during benign laparoscopic and robotic hysterectomy: a randomized controlled trial.

BACKGROUND: Postoperative pain continues to be an undermanaged part of the surgical experience. Multimodal analgesia has been adopted in response to the opioid epidemic, but opioid prescribing practices remain high after minimally invasive hysterectomy. Novel adjuvant opioid-sparing analgesia to optimize acute postoperative pain control is crucial in preventing chronic pain and minimizing opioid usage. OBJECTIVE: This study aimed to determine the effect of direct laparoscopic uterosacral bupivacaine administration on opioid usage and postoperative pain in patients undergoing benign minimally invasive (laparoscopic and robotic) hysterectomy. STUDY DESIGN: This was a single-blinded, triple-arm, randomized controlled trial at an academic medical center between March 15, 2021, and April 8, 2022. The inclusion criteria were patients aged >18 years undergoing benign laparoscopic or robotic hysterectomy. The exclusion criteria were non-English-speaking patients, patients with an allergy to bupivacaine or actively using opioid medications, patients undergoing transversus abdominis plane block, and patients undergoing supracervical hysterectomy or combination cases with other surgical services. Patients were randomized in a 1:1:1 fashion to the following uterosacral administration before colpotomy: no administration, 20 mL of normal saline, or 20 mL of 0.25% bupivacaine. All patients received incisional infiltration with 10 mL of 0.25% bupivacaine. The primary outcome was 24-hour oral morphine equivalent usage (postoperative day 0 and postoperative day 1). The secondary outcomes were total oral morphine equivalent usage in 7 days, last day of oral morphine equivalent usage, numeric pain scores from the universal pain assessment tool, and return of bowel function. Patients reported postoperative pain scores, total opioid consumption, and return of bowel function via Qualtrics surveys. Patient and surgical characteristics and primary and secondary outcomes were compared using chi-square analysis and 1-way analysis of variance. Multiple linear regression was used to identify predictors of opioid use in the first 24 hours after surgery and total opioid use in the 7 days after surgery. RESULTS: Of 518 hysterectomies screened, 410 (79%) were eligible, 215 (52%) agreed to participate, and 180 were ultimately included in the final analysis after accounting for dropout. Most hysterectomies (70%) were performed laparoscopically, and the remainder were performed robotically. Most hysterectomies (94%) were outpatient. Patients randomized to bupivacaine had higher rates of former and current tobacco use, and patients randomized to the no-administration group had higher rates of previous surgery. There was no difference in first 24-hour oral morphine equivalent use among the groups (P=.10). Moreover, there was no difference in numeric pain scores (although a trend toward significance in discharge pain scores in the bupivacaine group), total 7-day oral morphine equivalent use, day of last opioid use, or return of bowel function among the groups (P>.05 for all). The predictors of increased 24-hour opioid usage among all patients included only increased postanesthesia care unit oral morphine equivalent usage. The predictors of 7-day opioid usage among all patients included concurrent tobacco use and mood disorder, history of previous laparoscopy, estimated blood loss of >200 mL, and increased oral morphine equivalent usage in the postanesthesia care unit. CONCLUSION: Laparoscopic uterosacral administration of bupivacaine at the time of minimally invasive hysterectomy did not result in decreased opioid usage or change in numeric pain scores.

Demonstration of Safe Entry Techniques for Laparoscopy.

STUDY OBJECTIVE: To demonstrate different techniques, and detail the considerations for obtaining primary laparoscopic access in gynecologic surgery. DESIGN: Video demonstration of the techniques with narrated discussion of each method. SETTING: The methods for primary entry in laparoscopy vary by location and technique [1,2]. There are inherent risks with any mode of primary entry, and the risks are also specific to each technique [3-6]. The choice for primary entry depends on the patient's anatomy, surgical history, pathology, and surgeon preference [1,2]. INTERVENTIONS: This video reviews considerations for choosing the safest entry point and tips for proper entry technique [4,7-10]. The entry sites reviewed include the umbilicus, left upper quadrant, right upper quadrant, and supraumbilical [11]. The entry technique can be either open (Hasson), closed (Veress), or by direct laparoscopic visualization [9,10,12-14]. CONCLUSION: No single laparoscopic entry technique is superior [3]. The safest and most successful entry method will vary by case characteristics and surgeon training.

The sticky business of adhesion prevention in minimally invasive gynecologic surgery.

PURPOSE OF REVIEW: The negative impact of postoperative adhesions has long been recognized, but available options for prevention remain limited. Minimally invasive surgery is associated with decreased adhesion formation due to meticulous dissection with gentile tissue handling, improved hemostasis, and limiting exposure to reactive foreign material; however, there is conflicting evidence on the clinical significance of adhesion-related disease when compared to open surgery. Laparoscopic surgery does not guarantee the prevention of adhesions because longer operative times and high insufflation pressure can promote adhesion formation. Adhesion barriers have been available since the 1980s, but uptake among surgeons remains low and there is no clear evidence that they reduce clinically significant outcomes such as chronic pain or infertility. In this article, we review the ongoing magnitude of adhesion-related complications in gynecologic surgery, currently available interventions and new research toward more effective adhesion prevention. RECENT FINDINGS: Recent literature provides updated epidemiologic data and estimates of healthcare costs associated with adhesion-related complications. There have been important advances in our understanding of normal peritoneal healing and the pathophysiology of adhesions. Adhesion barriers continue to be tested for safety and effectiveness and new agents have shown promise in clinical studies. Finally, there are many experimental studies of new materials and pharmacologic and biologic prevention agents. SUMMARY: There is great interest in new adhesion prevention technologies, but new agents are unlikely to be available for clinical use for many years. High-quality effectiveness and outcomes-related research is still needed.

The increasing use of robot-assisted approach for hysterectomy results in decreasing rates of abdominal hysterectomy and traditional laparoscopic hysterectomy.

PURPOSE: To compare the frequency of minimally invasive surgical approach to hysterectomy between two time periods, during which the use of the robotic technique has rapidly increased. METHODS: This study is a retrospective review of 623 consecutive patients who underwent hysterectomy for benign indications at the Division of Minimally Invasive Gynecologic Surgery via laparoscopic, robotic, laparotomy, mini-laparotomy and vaginal approaches from July 2004 to June 2010. "Early period" refers to the first 311 patients, and "late period" refers to the remaining 312 patients. RESULTS: The characteristics of patients from the early and late periods were comparable in terms of age, BMI and uterine weight. The rates of hysterectomy by laparotomy, traditional laparoscopy, robotic, vaginal, and mini-laparotomy were significantly different between the early and late periods (17.7 to 5.4%, 39.5 to 17.6%, 23.8 to 64.1%, 5.8 to 4.8% and 13.2 to 8%, respectively, P < 0.01), with the overall rates of hysterectomies completed via a minimally invasive approach increasing from 82.3 to 94.6%, respectively (P < 0.01). There were no differences in surgical complications between the two periods. CONCLUSION: Increased utilization of a robotic approach to hysterectomy correlates with decreasing rates of abdominal hysterectomy concurrent with decreasing rates of traditional laparoscopic hysterectomy. This shift in surgical approach to hysterectomy, while beneficial in increasing the rates of minimally invasive approach to hysterectomy, may have significant economic implications due to the higher cost of robotic surgery.

Perioperative outcomes of robotic versus laparoscopic hysterectomy for benign disease.

BACKGROUND AND OBJECTIVES: We compared the perioperative outcomes of hysterectomy performed by robotic (RH) versus laparoscopic (LH) routes for benign indications using the Dindo-Clavien scale for classification of the surgical complications. METHODS: Retrospective chart review of all patients who underwent robotic (n=288) and laparoscopic (n=257) hysterectomies by minimally invasive surgeons at the University of Michigan from March 2001 until June 2010. RESULTS: Age, body mass index, operative time, and estimated blood loss were not statistically different between groups. The RH subgroup had a larger uterine weight (LH 186.4±130.6 g vs RH 234.9±193.9 g, P=.001), higher prevalence of severe adhesions (13.2% vs 23.3%, respectively, P=.003), and stage III-IV endometriosis (4.7% vs 15.3%, respectively, P<.05). There were no differences in the rates of Dindo-Clavien grade I, grade II, and grade III surgical complications between the RH and LH groups (9.7%, 13.2%, and 3.1%, respectively, in the RH group vs 6.2%, 9.3%, and 5.8%, respectively, in the LH group, P>.05). However, the rates of urinary tract infection were higher in the RH group (LH 2.7% vs RH 6.9%, P=.02), whereas the conversion to laparotomy rate was higher in the LH group (LH 6.2% vs RH 1.7%, P=.007). CONCLUSIONS: Perioperative outcomes for laparoscopic and robotic hysterectomy for benign indications appear to be equivalent.

Risk Factors for Postoperative Narcotic Use in Benign, Minimally-Invasive Gynecologic Surgery.

Background and Objectives: To evaluate postoperative opioid use after benign minimally-invasive gynecologic surgery and assess the impact of a patient educational intervention regarding proper opioid use/disposal. Methods: Educational pamphlets were provided preoperatively. Patients underwent hysterectomy, myomectomy, or other laparoscopic procedures. Opioid prescriptions were standardized with 25 tablets oxycodone 5mg for hysterectomy/myomectomy, 10 tablets oxycodone 5mg for LSC (oral morphine equivalents were maintained for alternatives). Pill diaries were reviewed and patient surveys completed during postoperative visits. Results: Of 106 consented patients, 65 (61%) completed their pill diaries. Median opioid use was 35 OME for hysterectomy (∼5 oxycodone tablets; IQR 11.25-102.5), 30 OME for myomectomy (∼4 tablets; IQR 15-75), and 18.75 OME for laparoscopy (∼3 tablets; IQR 7.5-48.75). Median last post-operative day (d) of use was 3d for hysterectomy (IQR 2, 8), 4d for myomectomy (IQR 1, 7), and 2d for laparoscopy (IQR 0.5-3.5). One patient (myomectomy) required a refill of 5mg oxycodone. No difference was found between total opioid use and presence of pelvic pain, chronic pain disorders, or psychiatric co-morbidities. Overall satisfaction with pain control (>4 on a 5-point Likert scale) was 91% for hysterectomy, 100% for myomectomy, 83% for laparoscopy. Of the 33 patients who read the pamphlet, 32(97%) felt it increased their awareness. Conclusion: Most patients required <10 oxycodone 5mg tablets, regardless of procedure with excellent patient satisfaction. A patient education pamphlet is a simple method to increase knowledge regarding the opioid epidemic and facilitate proper medication disposal.

Predictors of Minimally Invasive Myomectomy in the National Inpatient Sample Database, 2010-2014.

BACKGROUND AND OBJECTIVES: This study aims to characterize the utilization of minimally invasive myomectomy in the United States and to identify the patient and hospital factors associated with surgical approach to myomectomy. METHODS: This is a cross-sectional study using the National Inpatient Sample database. We extracted women aged 18-50 years who underwent open and minimally invasive (laparoscopic and robotic) myomectomy (MIM) from January 1, 2010-December 31, 2014. Descriptive statistics were obtained for patient and hospital characteristics. We then performed multivariable logistic regression to examine the association of patient (age, race, insurance status, median household income) and hospital (bed size, teaching status, for-profit status, census region, cases volume) characteristics with the likelihood of undergoing MIM. RESULTS: Of 114,850 myomectomy cases, 8,330 (7%) underwent MIM and 106,520 (93%) were open. Over time, the proportion of MIM remained very low and slightly decreased from 8.2% in 2010 to 6.1% in 2014 (p-for-trend: 0.001). Most hospitals performed few MIM per year, with 50% performing five or less, and 25% performing three or fewer per year. African American, Hispanic, and women of other races were less likely to undergo MIM compared to Caucasian women (adjusted odds ration [OR] 0.57, 95% confidence interval [CI] 0.50-0.64; 0.71, 95% CI 0.60-0.83; 0.62, 95% CI 0.52-0.74, respectively). Women in the West (adjusted odds ratio (aOR) 1.23, 95% CI 1.04-1.46) and Midwest (aOR 1.27, 95% CI 1.07-1.52) had higher odds of undergoing MIM. CONCLUSION: MIM appears to be an underutilized modality, accounting for less than10% of myomectomies. This underutilization disproportionally affects minority women.

Comparison of 2 minimally invasive routes for hysterectomy of large uteri.

OBJECTIVE: To compare the perioperative outcomes associated with 2 minimally invasive surgical routes for the hysterectomy of large fibroid uteri. METHODS: Retrospective review of 84 women undergoing hysterectomy via minilaparotomy (n=54) or robot-assisted laparoscopy (n=30) for uteri weighing at least 500g. Outcome measures included hemorrhage (blood loss of 500mL or more) and postoperative length of stay. RESULTS: Unadjusted mean blood loss (560.2±507.4mL versus 165.0±257.5mL, P<0.001), rate of hemorrhage (40.7% versus 6.7%, P=0.001, odds ratio 6.1 [95% confidence interval 1.5-24.2]), and rate of blood transfusion (14.8% versus 0%, P=0.03 ) were all higher with minilaparotomy than with robot-assisted surgery, while the median postoperative stay was significantly shorter with robotic surgery (2 [range 1-4] days versus 1 [range 0-7] days, P<0.01). After adjusting for differences in uterine weight using a multivariate linear regression analysis, the mean blood loss and the rate of hemorrhage were no longer significantly different between the 2 groups. CONCLUSION: The minilaparotomy approach may be used to remove very large uteri and does not require specialized and expensive equipment, or advanced endoscopic training. The robotic approach, when feasible, allows for early postoperative discharge.
