Hysterectomy Techniques and Outcomes for Benign Large Uteri: A Systematic Review.

To identify the optimal hysterectomy approach for large uteri in gynecologic surgery for benign indications from a perioperative morbidity standpoint. PubMed and Embase databases were searched from inception through September 19, 2022. Meta-analyses were conducted as feasible. This review included studies that compared routes of hysterectomy with or without bilateral salpingo-oophorectomy for large uteri (12 weeks or more or 250 g or more) and excluded studies with any concurrent surgery for pelvic organ prolapse, incontinence, gynecologic malignancy, or any obstetric indication for hysterectomy. The review included 25 studies comprising nine randomized trials, two prospective, and 14 retrospective nonrandomized comparative studies. Studies were at high risk of bias. There was lower operative time for total vaginal hysterectomy compared with laparoscopically assisted vaginal hysterectomy (LAVH) (mean difference 39 minutes, 95% CI, 18-60) and total vaginal hysterectomy compared with total laparoscopic hysterectomy (mean difference 50 minutes, 95% CI, 29-70). Total laparoscopic hysterectomy was associated with much greater risk of ureteral injury compared with total vaginal hysterectomy (odds ratio 7.54, 95% CI, 2.52-22.58). There were no significant differences in bowel injury rates between groups. There were no differences in length of stay among the laparoscopic approaches. For LAVH compared with total vaginal hysterectomy, randomized controlled trials favored total vaginal hysterectomy for length of stay. When rates of blood transfusion were compared between these abdominal hysterectomy and robotic-assisted total hysterectomy routes, abdominal hysterectomy was associated with a sixfold greater risk of transfusion than robotic-assisted total hysterectomy (6.31, 95% CI, 1.07-37.32). Similarly, single studies comparing robotic-assisted total hysterectomy with LAVH, total laparoscopic hysterectomy, or total vaginal hysterectomy all favored robotic-assisted total hysterectomy for reduced blood loss. Minimally invasive routes are safe and effective and have few complications. Minimally invasive approach (vaginal, laparoscopic, or robotic) results in lower blood loss and shorter length of stay, whereas the abdominal route has a shorter operative time.

Robotic-assisted hysterectomy for benign gynecologic disease in the United States: in-hospital use of opioid and non-opioid analgesics.

To compare the in-hospital opioid and non-opioid analgesic use among women who underwent robotic-assisted hysterectomy (RH) vs. open (OH), vaginal (VH), or laparoscopic hysterectomy (LH). Records of women in the United States who underwent hysterectomy for benign gynecologic disease were extracted from the Premier Healthcare Database (2013-2019). Propensity score methods were used to create three 1:1 matched cohorts stratified in inpatients [RH vs. OH (N = 16,821 pairs), RH vs. VH (N = 6149), RH vs. LH (N = 11,250)] and outpatients [RH vs. OH (N = 3139), RH vs. VH (N = 29,954), RH vs. LH (N = 85,040)]. Opioid doses were converted to morphine milligram equivalents (MME). Within matched cohorts, opioid and non-opioid analgesic use was compared. On the day of surgery, the percentage of patients who received opioids differed only for outpatients who underwent RH vs. LH or VH (maximum difference=1%; p<0.001). RH was associated with lower total doses of opioids in all matched cohorts (each p<0.001), with the largest difference observed between RH and OH: median (IQR) of 47.5 (25.0-90.0) vs. 82.5 (36.0-137.0) MME among inpatients and 39.3 (19.5-66.0) vs. 60.0 (35.0-113.3) among outpatients. After the day of surgery, fewer inpatients who underwent RH received opioids vs. OH (78.7 vs. 87.5%; p<0.001) or LH (78.6 vs. 80.6%; p<0.001). The median MME was lower for RH (15.0; 7.5-33.5) versus OH (22.5; 15.0-55.0; p<0.001). Minor differences were observed for non-opioid analgesics. RH was associated with lower in-hospital opioid use than OH, whereas the same magnitude of difference was not observed for RH vs. LH or VH.

Effect of Uterine Weight on the Surgical Outcomes of Robot-Assisted Hysterectomy in Benign Indications.

Background Uterine weight is an important factor in determining the complexity of a hysterectomy. Although greater uterine weight increases operative time and blood loss in open or laparoscopic surgery, it remains uncertain whether this applies to robot-assisted hysterectomy. This study aimed to investigate the effect of uterine weight on the surgical outcomes of robot-assisted hysterectomy. Methods We conducted a retrospective cohort study involving 872 patients who underwent robot-assisted hysterectomies at our institution between January 2019 and June 2022. Of these, 724 cases were analyzed and classified into four groups based on uterine weight: <250 g (377 patients), 250-500 g (253 patients), 500-750 g (69 patients), and ≥750 g (25 patients). We performed univariate analysis with the following endpoints: operation time, blood loss, postoperative hospital stay, complication rate, conversion to laparotomy rate, and blood transfusion rate. Results Operating time and blood loss increased significantly with greater uterine weight in the four groups (both p-values <0.01), but postoperative hospital stay and complication rate did not increase (p = 0.448, p = 0.679, respectively). None of the patients underwent conversion to laparotomy or blood transfusion. Conclusion Although the operating time for robot-assisted hysterectomy and blood loss increased with greater uterine weight, the complications and length of postoperative hospital stay were similar between groups. Robot-assisted hysterectomy is safe in cases of much uterine weight.

Initial experience and surgical outcomes of robotic-assisted total hysterectomy using the da Vinci SP surgical system.

The da Vinci SP surgical system is a surgical platform capable of implementing robotic-assisted surgery through a single port and was first introduced in Japan at our hospital. In this paper, we describe our experience of the initial introduction of the da Vinci SP surgical system and its surgical outcomes. This is the first report on the surgical outcomes of using da Vinci SP, and its comparison with the conventional system in Japan. After developing an application for a highly difficult new medical technology in-house, we compared the surgical outcomes (median values) of 15 patients who had undergone total hysterectomy at our hospital using the da Vinci SP (1-port) system (SP group) for uterine myoma after March 2023 and of 154 patients who underwent total hysterectomy using the conventional da Vinci Xi (four ports) system (Xi group) for uteri weighing <500 g. The results of the comparison of the characteristics between 15 patients in the SP group and 154 patients in the Xi group were as follows: uterus weight (g): 230 (90-500) versus 222 (55-496) (p = .35); surgical time (minutes): 199 (171-251) versus 198 (88-387) (p = .63); intraoperative blood loss (mL): 13 (5-82) versus 20 (2-384) (p = .17); and rate of surgical complication (%): 0.0 versus 1.3 (p = .66). The data indicated a comparable weight of the resected uterus, surgical time, intraoperative blood loss, and rate of surgical complications between the two groups. Robotic-assisted total hysterectomy using the da Vinci SP surgical system allowed clinicians to safely perform surgeries according to the conventional systems.

The first robotic-assisted hysterectomy below the bikini line with the Dexter robotic system™.

Robotic-assisted hysterectomy (RAH) is a widely accepted minimally invasive approach for uterus removal. However, as RAH is typically performed in the umbilical region, it usually results in scars in cosmetically suboptimal locations. This is the first case of RAH with cervicosacropexy performed below the bikini line, using the new Dexter robotic system™. The aim of this article is to show the surgical steps of the first RAH with cervicosacropexy performed below the bikini line with the new Dexter robotic system™ (Distalmotion), and furthermore assess the feasibility of this approach using this robotic platform. A 43-year-old woman with uterine adenomyosis and recurrent uterine prolapse underwent a robotic-assisted subtotal hysterectomy with cervicosacropexy, performed below the bikini line, using the Dexter robotic system™, at the Clinic of Gynecology and Obstetrics at Universitätsklinikum Schleswig-Holstein (UKHS) in Kiel, Germany. Perioperative data, surgical approach specifics, objective, and subjective outcomes of this new approach. The procedure was performed without intra-operative complications; estimated blood loss was 10 ml. Operative time was 150 minutes, console time 120 minutes, total docking time 6 minutes. Dexter performed as expected; no device-related issues or robotic arm collisions occurred. The patient did not require pain medication and was released on the second postoperative day. RAH performed below the bikini line using the Dexter robotic system™ is a feasible, safe, and adequate procedure. These initial results should be confirmed and further extensively refurbished with larger patient cohorts, and functional and psychological outcomes need further investigation.

Robot-Assisted Hysterectomy Using the Double-Bipolar Method

ObjectiveTo demonstrate the efficacy of the double-bipolar method in a benign hysterectomy. DesignStepwise demonstration of the technique with a narrative video. SettingThe double-bipolar method was first reported in 2011 [1] and is gaining popularity in Japan; however, its usefulness in robot-assisted hysterectomy is under-reported. When unexpected bleeding occurs during robot-assisted hysterectomy using a monopolar technique, corrective measures may be prolonged and often require changing forceps. The Maryland forceps have 4 functions, including incision, dissection, grasping, and coagulation, which enable rapid responses to bleeding and reduce forceps changes and cost. Previously, we reported the usefulness of the double-bipolar technique in other surgical procedures [2,3]. Herein, we present a case of robot-assisted hysterectomy using this technique at an urban general hospital, including detailed insights into its execution. InterventionsA 45-year-old female patient presented to our hospital with painful menstrual bleeding. Magnetic resonance imaging revealed an 8-cm myoma in the posterior wall of the uterine cervix. Consequently, a robot-assisted hysterectomy was performed using right-handed Maryland forceps (Intuitive, Sunnyvale, CA) and the ForceTriadTM Energy Platform (Medtronic, Minneapolis, MN) in the macro mode, with an output of 60 W. This configuration ensured a consistent electronic output, regardless of the electrical resistivity of the target tissues, facilitating precise incisions using a momentary high voltage [4]. The surgical duration was 60 minutes, and the estimated blood loss was 5 mL. ConclusionThe highly versatile double-bipolar method uses one forceps for incision, dissection, coagulation, and grasping and is useful in gynecological surgery. Video Abstract [Display omitted]

Reducing the Time Before the Console in Robotic-Assisted Laparoscopic Hysterectomy

Robotic-assisted surgery enables precise manipulations with magnified vision, stereoscopic vision, and forceps with multi-joint functions. It requires unique procedures such as position setting, port placement, roll-in, and docking, which lead to prolonged operation and anesthesia time. Five conditions described below were established at our institution to reduce the time to the initiation of console: (1) changing the patients' position from the flat lithotomy position to the spread legs position; (2) attaching a Hasson cone to hold the umbilical cannula stable; (3) changing the cannula's obturator (inner tube) from blunt to bladeless; (4) fixing the team, and (5) conducting regular docking training. These outcomes were examined in this study. The study included 77 patients who underwent robotic-assisted total hysterectomy for benign uterine disease and stage IA uterine cancer at our individual institution between April 2019 and July 2022. We compared the median time from anesthesia to console initiation between the first half group (cases 1-40) and the second half group (cases 41-77). The former required 91.5 (53-131) minutes, whereas the latter required 59 (37-126) minutes. Appropriate equipment selection and team education can reduce the time to console initiation.

First report of robotic-assisted total hysterectomy using the Hugo™ RAS system.

This study describes the first reported treatment of a benign gynecological disease with the Medtronic's Hugo™ RAS System, the first robot-assisted device used in the field of gynecology in Japan. Patients who underwent robot-assisted total laparoscopic hysterectomy with the Hugo™ RAS System at the Tottori University Hospital between March 2023 and June 2023 were included in this study. In the first case, the patient was in her 40s and had uterine fibroids. We describe our experience and compare the device with the conventional da Vinci surgical system. We discuss the key features of the Hugo system (including the independent arms, open console, and pistol-shaped handle), the convenience of robotic surgery, the potential to improve quality of life, and how this technology could revolutionize the field of surgery.

Robotic Vaginal Cuff Closure During Radical Hysterectomy for Early-Stage Cervical Cancer: The Bruges Method.

The only randomized trial (LACC trial, Laparoscopic Approach to Cervical Cancer), published in 2018, comparing the oncologic outcomes of minimally invasive and open surgery in early-stage cervical cancer, has shown inferior disease-free and overall survival for minimally invasive surgery. Subsequent large retrospective cohort studies of centers with long-standing experience in minimally invasive surgery and large nationwide cohort studies have shown that both the laparoscopic and robotic approaches have similar survival outcomes as the open surgery group in the LACC trial. Important protective measures to avoid tumor spillage in the peritoneal cavity during colpotomy were the closure of the vaginal cuff and avoiding the use of a uterine manipulator. Several methods have been described to close the vaginal cuff, mainly by a vaginal approach. Here we describe with a video a new technique of vaginal cuff closure during a robotic-assisted radical hysterectomy. During the robotic procedure, a purse string barbed suture is placed through the vaginal walls in order to close the vagina prior to colpotomy. The technique is a feasible, relatively fast, and easy-to-learn addition to the robotic radical hysterectomy procedure in early-stage cervical cancer.

Robotic-assisted laparoscopic colpectomy combined with a hysterectomy and bilateral salpingo-oophorectomy versus a vaginal colpectomy in trans masculine individuals

Background: Colpectomy entails the surgical removal of the vaginal epithelium. It may be performed in trans-masculine individuals as gender-affirming surgery. Vaginal colpectomy is a complex procedure with potentially severe complications. As alternative, robotic-assisted laparoscopic colpectomy combined with robotic-assisted laparoscopic hysterectomy and possible bilateral salpingo-oophorectomy (RAC+) can be performed. Aim: To compare surgical outcomes of robotic-assisted colpectomy combined with a hysterectomy and bilateral salpingo-oophorectomy with a vaginal colpectomy after previous hysterectomy in trans masculine patients. Methods: A single-center retrospective cohort study included 310 transgender men who underwent either robotic-assisted colpectomy combined with a hysterectomy and bilateral salpingo-oophorectomy (RAC+) (n = 140) or vaginal colpectomy (n = 170) between January 2006 and December 2019. Surgical details and clinical outcomes were collected from all patients. Results: The median intra-operative blood loss was 100 mL (50–200) in RAC + and 300 mL (200–450) in vaginal colpectomy (p < 0.01). The median duration of hospital stay was 2 days (1–2) in the RAC + group and 3 days (2–4) in the vaginal group (p < 0.01). In the RAC + group 63 (45%) peri-operative complications were reported, compared to 93 (54.7%) in the vaginal group [OR 0.7 (0.4–1.1)]. The main difference was found in intra-operative complications (RAC+ 0.7% vs. vaginal 10.6%). Furthermore, the total number of complications graded 3a and higher was significantly lower in the RAC + group [OR 0.3 (0.2–0.7)]. Conclusion: Although RAC + entailed a more extensive procedure, compared to vaginal colpectomy, RAC + had a lower risk of severe peri-operative complications, requiring re-intervention; intra-operative blood loss was lower and hospital stay shorter. Both routes of colpectomy are complex procedures with potentially severe complications. Future studies are needed to study whether robot–colpectomy could be a safe alternative to vaginal colpectomy in patients with a previous hysterectomy.

Comparison perioperative outcomes for endometrial cancer staging via traditional laparotomy, laparoscopy and robotic-assisted surgery: short term initial experience

Abstract: &#x0D; Aim: To compare the perioperative outcomes of traditional abdominal hysterectomy (TAH), total laparoscopic hysterectomy (TLH), and robotic-assisted hysterectomy (TRH) for endometrial cancer staging, which is the most common gynecological cancer type in Turkey Materials and Methods: Fifty eight women who underwent endometrial cancer staging surgery were performed by a same gynecologic oncologist (E.B.) from February 2015 to May 2016 in Sağlık Bilimleri University Adana Numune Hospital. The primary outcome measure was perioperative complications. The secondary outcome were operative time, postoperative hemoglobin drop, blood transfusion rates and length of the hospital stay. Results: Three groups were identified.(TAH, n=23; TLH, n=10; TRH, n=25) There were no statistically significant differences between the groups in terms of age, parity, grade and depth of myometrial invasion. Overall complication rate was higher in TAH group. TRH and TLH patients were less likely to have renal failure, urinary tract infection and postoperative fever compared to TAH patients. A significantly lower drop in hemoglobin was detected in the TRH group compared with the other groups. (p= 0,797) Mean operative time was longer in TRH cases than TLH and TAH cases (300, 230, 165 minutes, respectively). The median lengths of hospitalization for TAH, TLH, and TRH patients were 5, 3, and 2 days, respectively (p &lt; 0.0001). There were significantly fewer blood transfusion requirements in minimal invasive surgery groups (0/10 case in TLH and 3/25 cases in TRH) than traditional approaches (5/23 cases in TAH ). Conclusions:With our short term initial experience, minimally invasive surgical approach resulted in superior perioperative outcomes. Despite longer operative times, the results from this study suggest that robotic-assisted surgical staging in the management of endometrial cancer is both feasible and associated with a shorter length of hospitalization.

Impact of Patient Body Mass Index on Post-Operative Recovery from Robotic-Assisted Hysterectomy.

A longitudinal, descriptive, prospective, and prolective study of individuals with endometrial or cervical cancer/pre-cancer diagnoses and high BMI (over 35 kg/m2) undergoing RH was conducted. Of the 53 participants recruited, 3 (6%) were converted to open surgery. The 50 RH participants had median BMI 42 kg/m2 (range 35 to 60): the range 35-39.9 kg/m2 had 17 cases; the range 40-44.9 kg/m2 had 15 cases; 45-49.9 kg/m2 8 cases; and those ≥50 kg/m2 comprised 10 cases. The mean RH operating time was 128.1 min (SD 25.3) and the median length of hospital stay was 2 days (range 1-14 days). Increased BMI was associated with small, but statistically significant, increases in operating time and anaesthetic time, 65 additional seconds and 37 seconds, respectively, for each unit increase in BMI. The median self-reported time for individuals who underwent RH to return to their pre-operative activity levels was 4 weeks (range 2 to >12 weeks). There was a significant improvement in pain and physical independence scores over time (p = 0.001 and p < 0.001, respectively) and no significant difference in scores for overall QOL, pain, or physical independence scores was found between the BMI groups. Patient-reported recovery and quality of life following RH is high in individuals with high BMI (over 35 kg/m2) and does not appear to be impacted by the severity of obesity.

Nationwide trends in and regional factors associated with minimally invasive hysterectomy for benign indications in Japan

ObjectiveTo examine the prevalence trends of minimally invasive hysterectomy for benign indications in Japan and investigate regional disparities. Study DesignA retrospective cohort and ecological study using “The National Database of Health Insurance Claims and Specific Health Checkups of Japan (NDB) Open Data”. SettingNationwide Japan. PatientsIndividuals who underwent hysterectomy for benign indications from 2014 to 2020. InterventionsTrend analysis of minimally invasive surgery (MIS) rates through laparoscopic hysterectomies (LH) and robotic-assisted laparoscopic hysterectomies (RA-LH) at the national and prefecture levels. Examination of regional factors contributing to the disparity in MIS implementation rates by second medical service area (SMSA). ResultsThe number of LH has increased from 16,016 in 2014 to 27,755 in 2020. The nationwide MIS hysterectomy rate increased from 29% in 2014 to 55% in 2020 (p less than 0.001). More than 50% of hysterectomies have been performed as MIS since 2019. There was an increasing trend in MIS rates in all age groups. All prefectures except one showed a significant upward trend (p less than 0.05) in the MIS rates, but MIS rates varied widely (23–84%). In a multivariable model, the MIS was more likely to be performed in the SMSAs in western Japan (p = 0.011), in the SMSAs where the number of laparoscopy-qualified gynecologists is 5–10 (p = 0.013), and 11 or higher (p less than 0.001). ConclusionsThis study reveals a shift towards minimally invasive surgery (MIS) in total hysterectomy procedures in Japan. However, significant disparities in the prevalence of MIS hysterectomy exist, potentially influenced by the number of laparoscopy-qualified gynecologists.
