Spontaneous Parasitic Pedunculated Myoma Presenting the Absence of Uterine Smooth Muscle Cells in the Stalk — A Case Report

A few cases of spontaneous parasitic myoma have been reported. However, its cause remains unidentified. We report a case of spontaneous parasitic pedunculated subserosal myoma with pathological findings presenting with the absence of uterine smooth muscle cells in the stalk observed during robotic-assisted laparoscopic hysterectomy. A 51-year-old patient (G1P0) with no prior surgical history underwent a robotic-assisted laparoscopic hysterectomy. An approximately 3 cm-pedunculated subserosal myoma was found attached to the retroperitoneum. The stalk was sealed and separated and the myoma with retroperitoneal adipose tissue was resected. The stalk was pathologically identified to lack uterine smooth muscle cells and contain only muscular arteries and fibrous connective tissues. Thus, it might be hypothesized that after the myoma received collateral parasitic blood flow from the attached retroperitoneum, the stalk degenerated, and uterine smooth muscle cells were lost through an unknown mechanism, possibly underlying the development of spontaneous parasitic myomas.

Bilateral iliac embolization for delayed postoperative vaginal cuff bleeding complicated by non-target embolization of the labia

This case describes a 41 year-old female who underwent a robotic-assisted total laparoscopic hysterectomy in the setting of adenomyosis which was complicated by postoperative vaginal bleeding requiring additional surgical management. She continued to have vaginal bleeding following re-operation and the decision was made to proceed with iliac artery embolization with Interventional Radiology. Following the embolization, the patient’s bleeding was well controlled. While it is well known that uterine artery embolization is an option for management of bleeding for patients with fibroids, there are no current cases reported in the literature of embolization following hysterectomy. This is a unique case with potential clinical impact for future management of postoperative bleeding complications.

Feasibility and safety evaluation of ultra-remote robot-assisted laparoscopic hysterectomy

ObjectiveTo assess the safety and feasibility of ultra-remote robot-assisted laparoscopic hysterectomy using the Edge Multi-Port Endoscopic Surgical Robot MP1000 (Shenzhen Edge Medical Co., Ltd., Shenzhen, China) combined with 5G communication technology. MethodsA case of remote robot-assisted laparoscopic hysterectomy was successfully completed on May 2024 by using the Edge Multi-Port Endoscopic Surgical Robot MP1000 at Zhongnan Hospital of Wuhan University and the People's Liberation Army General Hospital, approximately 1, 200 ​km apart. The procedure was simultaneously broadcast during the 36th Annual Meeting of the International Society for Gynecologic Endoscopy in Conjuction with the Peking University Gynecologic Oncology Summit Forum. ResultsA 49-year-old female was hospitalized in the Department of Gynecology of Zhongnan Hospital of Wuhan University for frequent urination for half a year and increased menstrual flow for over a month. The patient was diagnosed with abnormal uterine bleeding caused by multiple uterine leiomyoma and endometrial polyps, combined with moderate anemia. There were no contraindications for surgery, and the patient had surgical indications. On May 2024, the patient underwent a 5G remote robot-assisted laparoscopic hysterectomy and bilateral salpingectomy under general anesthesia. The procedure was successful, with no surgical complications and no interruptions during the live broadcast. The intraoperative blood loss was approximately 20 ​mL, and the surgery lasted about 70 ​min. The bidirectional latency during the operation was around 19 ​ms, with no adverse events related to the robot or the network. The patient recovered well postoperatively and was discharged on the fourth day with no postoperative complications. ConclusionPreliminary findings indicate that ultra-remote robot-assisted laparoscopic hysterectomy is safe and feasible with the support of 5G communication technology. This surgery represents the first globally broadcast remote procedure in the field of gynecology, marking a new milestone in the stability and safety of China's remote medical technology. Remote robotic surgery is expected to be widely promoted in the future, providing services to patients in areas with limited medical resources.

A rare case of concomitant endometrioid adenocarcinoma arising from uterine adenomyosis and clear cell carcinoma arising from parametrial deep endometriosis

BackgroundCarcinomatous changes from the ectopic endometrial glands in endometriosis have been reported in many studies, but malignant transformation from uterine adenomyosis/adenomyoma is rare. And clear cell-like adenocarcinoma represents a seldom-encountered malignant pathological variant of ectopic endometrium.Case presentationThis case report presents a case of a 44-year-old nulliparous woman begun with abdominal pain and intestinal obstruction. Past medical history showed laparoscopic ovarian endometriotic cyst excision. Ultrasound indicated adenomyoma and a parametrial hypoechoic nodule with abundant blood flow signals and unclear boundaries. Deep invasive endometriosis was considered preoperatively. The patient underwent laparoscopic subtotal hysterectomy and bilateral adnexa resection. Chocolate cyst-like lesion was observed in the parametral lesion. Postoperative pathological examinations suggested endometrioid adenocarcinoma arising from eutopic endometrium and adenomyoma. Ectopic endometrium in the myometrium combined with atypical hyperplasia and formation of endometrioid adenocarcinoma. Left parametrial lesions suggested poorly differentiated endometrioid adenocarcinoma combined with clear cell carcinoma. CD10 + endometrial stromal cells were observed surrounding tumor cell masses. Combined with surgical founding and pathological characters of the left parametrial adenocarcinoma, the parametrial lesions were more likely to be carcinomatous changes of the original deep endometriosis.The patient underwent subsequent transabdominal tumor cell reduction surgery and chemotherapy.ConclusionWe herein present a rare case of combined endometrioid adenocarcinoma arising from uterine adenomyosis and clear cell carcinoma arising from parametrial deep endometriosis that may help inspire additional studies in the future. The patient underwent robot-assisted laparoscopic subtotal hysterectomy, bilateral adnexa resection, deep endometriosis lesion resection and bilateral ureteral stent placement. Following surgery, a chemotherapy regimen of Taxol and Carboplatin was administered.

A Case of a Prolapsing Cervical Myoma Managed with Robot-assisted Total Laparoscopic Hysterectomy

The development of cervical fibroids is rare, but they are often symptomatic and can be associated with complications such as bleeding, pain, constipation, and prolapse. Necrosed, prolapsing fibroids can lead to massive acute hemorrhage. Treatment is, therefore, typically necessary, but surgical management is frequently technically difficult given distorted anatomy. We present several images of a prolapsing cervical fibroid treated by hysterectomy in a 53-year-old patient.

Comparison of surgical outcomes of da Vinci surgical systems X and Xi: A single-center study.

The da Vinci surgical systems (X and Xi) are fourth-generation systems marketed by Intuitive Inc. The X system is less expensive than the Xi system. This study compared the surgical outcomes of patients who underwent hysterectomy using the X and Xi systems. Data from 172 patients who underwent robot-assisted total hysterectomies by four surgeons between April 2019 and March 2023 were retrospectively analyzed in a single-center study. The patients were divided into two groups based on the surgical system used. Approval was granted by the Institutional Review Board of the Tottori University Hospital (22A134). All patients provided opt-out consent in accordance with the institutional guidelines. Operative time (126.6 ± 29.5 for X, 138.2 ± 38.5 for Xi, p = .227) and console time (92.9 ± 27.0 for X, 105.5 ± 34.7 for Xi, p = .089) were insignificantly shorter in group X than in group Xi after propensity score matching for age, body mass index, nulliparity, previous history of abdominal or pelvic surgery, preoperative diagnosis, and surgical approach. No significant differences between X and Xi were observed in a subgroup analysis of patients who underwent robot-assisted total laparoscopic hysterectomy without lymphadenectomy (operative time: 199.0 ± 26.5 for X, 221.5 ± 45.1 for Xi, p = .227; console time: 162.1 ± 25.0 for X, 178.3 ± 0.314 for Xi, p = .314). Perioperative outcomes for the X and Xi da Vinci surgical systems were equivalent. The cost-effective X system may allow the widespread use of robotic surgeries.

Case Report of Lipomyoma

Report: Uterine lipoleiomyoma are rare forms of leiomyomas that are often only described in literature as case reports. Lipoleiomyomas could increase in size despite menopause and most commonly occur in postmenopausal women with an incidence rate of 0.03% to 0.2% Clinical symptoms of lipoleiomyoma are very similar to leiomyoma. Radiologic imaging can aid in the diagnosis of lipoleiomyoma with smooth muscle confined to the tumor periphery. In our case, we describe a 53y/o G0P0 perimenopausal patient who complained of abnormal uterine bleeding with irregular menses, urinary retention and difficulty completely emptying her bladder due to the large mass compressing her bladder. She was diagnosed with a large 8.8 cm hyperechoic lesion with internal vascularity arising from the central uterus/ endometrium. Radiology recommended a pelvic MRI for further differentiation of mass. Office hysteroscopy with endometrial biopsy was performed. Pathology confirmed limited inactive endometrium, benign endometrial surface epithelium. The patient requested a hysterectomy through a minimally invasive gynecologic surgery approach. A pelvic MRI was performed that revealed a large, round, circumscribed mass measuring 7.3 X 7.2 X 7.5 cm favoring to represent an intramural lipoleiomyoma. The patient had a robotic assisted laparoscopic hysterectomy which was uncomplicated. Final histopathologic diagnosis was uterine lipomyoma. As benign masses, management for lipoleiomyoma are guided by symptoms, fertility preservation desires, and whether or not a patient is a candidate for surgical intervention. Given the rarity of these cases, the histogenesis is still relatively unknown although various theories exist such as differentiation of embryonic fat cells, metaplastic changes of existing cells into fat cells, and pluripotent cell migration. Although there was not evidence of malignancy in our case report, certain literature has suggested the presence of coexisting malignancies and in an even rarer occasion the presence of liposarcoma from a lipoleiomyoma. More information is needed on these rare cases in order to further lead management and any recommendations regarding cancer screening on top of age related recommendations already in place.

Leiomyomatosis: A Rare Case of Mistaken Identity

Abstract: Diffuse uterine leiomyomatosis (DUL) is a rare benign uterine pathology that is often misdiagnosed as uterine leiomyomas. We present a case of a woman with abnormal uterine bleeding treated with multiple medical therapies without symptomatic relief. She underwent two surgeries, almost a year apart, with the histopathologic diagnosis of leiomyomas. After numerous failed attempts at medical and surgical treatments, the patient requested definitive surgery and underwent a robotic-assisted laparoscopic hysterectomy. Histopathologic analysis of the entire uterine specimen confirmed diffuse uterine leiomyomatosis. Case Report: A 31-year-old female was referred to our office with a history of abnormal uterine bleeding and heavy menstrual bleeding who failed hormonal therapies. Levonorgestrel-releasing intrauterine devices were inserted at two different times and were expelled due to heavy menses. Pelvic magnetic resonance imaging reported leiomyomas. The patient underwent hysteroscopy and a robotic-assisted myomectomy. Pathology revealed leiomyomas. Seven months after her first surgery, her bleeding recurred, and the patient became severely anemic, requiring hospitalization and transfusion of 2 units of packed RBCs. Over a year later, the patient underwent a second hysteroscopic and robotic myomectomy after failed medical therapies of tranexamic acid, progesterone medication, and gonadotropin-releasing hormone antagonist with minimal symptom relief. Her quality of life suffered tremendously due to ongoing AUB-HMB. After seven months, the patient requested definitive surgical therapy and underwent a robotic-assisted laparoscopic hysterectomy. Pathology reported diffuse uterine leiomyomatosis. Diffuse uterine leiomyomatosis is a rare benign uterine pathology that is often misdiagnosed as uterine leiomyomas. Early diagnosis of DUL is challenging and often inconclusive. Less than 50 diffuse uterine leiomyomatosis cases have been reported in the literature. The myometrium in DUL is almost entirely replaced by numerous ill-defined benign smooth muscle tumors. MRI offers mapping of the size, site, and distribution of leiomyomas, but findings are difficult to differentiate from DUL. The pathophysiology of DUL development remains poorly understood, with patients frequently complaining of abnormal uterine bleeding, heavy menstrual bleeding, fertility issues, and dysmenorrhea. DUL is often misdiagnosed as leiomyomas or adenomyosis clinically, given the similarity in manifestations. Leiomyomatosis is histologically characterized by the proliferation of smooth muscle cells forming fascicles and nodules, which blend with normal myometrium tissue. Hysterectomy is the definitive treatment of DUL, with this case report demonstrating the close similarity between the two.

Inpatient Hospital Costs and Route of Hysterectomy for Management of Benign Uterine Disease in the 90-Day Global Billing Period.

To compare inpatient hospital costs and complication rates within the 90-day global billing period among routes of hysterectomy. The Premier Healthcare Database was used to identify patients who underwent hysterectomy between 2000 and 2020. Current Procedural Terminology codes were used to group patients based on route of hysterectomy. Comorbidities and complications were identified using International Classification of Diseases codes. Fixed, variable, and total costs for inpatient care were compared. Fixed costs consist of costs that are set for the case, such as operating room time or surgeon costs. Variable costs include disposable and reusable items that are billed additionally. Total costs equal fixed and variable costs combined. Data were analyzed using analysis of variance, t test, and χ 2 test, as appropriate. Factors independently associated with increased total costs were assessed using linear mixed effects models. Multivariate logistic regression was performed to evaluate associations between the route of surgery and complication rates. A cohort of 400,977 patients were identified and grouped by route of hysterectomy. Vaginal hysterectomy demonstrated the lowest inpatient total cost ($6,524.00 [interquartile range $4,831.60, $8,785.70]), and robotic-assisted laparoscopic hysterectomy had the highest total cost ($9,386.80 [interquartile range $6,912.40, $12,506.90]). These differences persisted with fixed and variable costs. High-volume laparoscopic and robotic surgeons (more than 50 cases per year) had a decrease in the cost difference when compared with costs of vaginal hysterectomy. Abdominal hysterectomy had a higher rate of complications relative to vaginal hysterectomy (adjusted odds ratio [aOR] 1.52, 95% CI, 1.39-1.67), whereas laparoscopic (aOR 0.85, 95% CI, 0.80-0.89) and robotic-assisted (aOR 0.92, 95% CI, 0.84-1.00) hysterectomy had lower rates of complications compared with vaginal hysterectomy. Robotic-assisted hysterectomy is associated with higher surgical costs compared with other approaches, even when accounting for surgeon volume. Complication rates are low for minimally invasive surgery, and it is unlikely that the robotic-assisted approach provides an appreciable improvement in perioperative outcomes.

Robotic-assisted laparoscopic radical hysterectomy for early-stage cervical cancer: The more experienced the bedside assistant, the better?

BackgroundAim to investigate the impact of bedside assistant's work experience and learning curve on the short-term safety and efficacy in robotic-assisted laparoscopic radical hysterectomy for early-stage cervical cancer. MethodsOur research retrospectively retrieved 120 cases of early-stage cervical cancer patients who underwent robotic-assisted laparoscopic radical hysterectomy at the First Affiliated Hospital of Guangxi Medical University. According to the different work experiences of the two bedside assistants (BA), patients were divided into a research group (inexperienced BA 1) and a control group (experienced BA 2). Furthermore, the learning curves of these BAs were plotted separately and divided into two distinct phases by cumulative summation: the first learning phase and the second master phase. ResultIn terms of work experience, comparing BA 1 with BA 2 who was more experienced, although the average operative time was prolonged by 29 min (P＜0.001), it did not increase the incidence of operative complication [24.4 % VS 29.1 %, P = 0.583], positive resection margin [4.9 % VS 7.6 %, P = 0.714], intraoperative organ damage [0 % VS 2.5 %, P = 0.546] and there was no significant difference in the number of lymph nodes [19 VS 15, P = 0.103]. Additionally, comparing two distinct phases of the same bedside assistant, there was no significant increasing rate in terms of operative complication, positive resection margin, intraoperative organ damage, and the number of lymph nodes (P＞0.05) neither BA 1 nor BA 2, except for a slight extension of operative time about 20 min in learning phase (P＜0.05). ConclusionIn robotic-assisted laparoscopic radical hysterectomy for early-stage cervical cancer, work inexperience and the learning phase of BA only result in a slight extension of operative time, without causing worse short-term surgical outcomes.

Intraoperative bladder visualization by indocyanine green filling and subsequent washout in endoscopic hysterectomy: ICG-Washout method.

Despite a potential risk of bladder injury in laparoscopic hysterectomy (LH) and robot-assisted LH (RaLH), an intraoperative method for delineating the entire bladder with indocyanine green (ICG) has not been established. We conducted a preliminary experiment using porcine bladders to verify the appropriate amount of ICG for intraoperative bladder visualization. Afterward, intraoperative bladder visualization was tried in LH and RaLH in two patients suspected of having adhesions around the bladder after previous abdominal surgery. Although near-infrared (NIR) fluorescence was well observed through the wall of the porcine bladder filled with ICG solution at a concentration of 0.024 mg/mL, the subsequent replacement of the ICG solution with saline made the NIR fluorescence brighter. In both patients, the bladder was successfully delineated by NIR fluorescence after filling the bladder with ICG solution and the subsequent washout with saline. The ICG-Washout method for locating the bladder by NIR fluorescence could be useful in LH and RaLH.

Robotic-assisted Versus Conventional Laparoscopic Hysterectomy for Benign Gynecological Conditions: A Systematic Review and Meta-analysis.

Minimally invasive gynecologic surgery is safe and feasible procedure for benign gynaecological conditions with less morbidity. To determine the best approach in benign gynecology and establish superiority of robotic over conventional laparoscopic hysterectomy in terms of safety and effectiveness. Search strategy: Electronic databases: MEDLINE, Embase, CENTRAL (the Registry of Controlled Clinical Studies of the Cochrane Collaboration), Google scholar, Pubmed and Scopus were searched from 2010-2022. Selection criteria: All randomized controlled trials and quasi-randomised trials which compared robotic versus conventional laparoscopic hysterectomy were included to conduct this systematic review and meta-analysis to investigate compared to traditional approaches. Only five RCTs (326 patients in total) comparing robotic and conventional laparoscopic hysterectomy were included after a comprehensive literature search. Results of our analysis showed no clear benefit in any of the two techniques in operating time, estimated blood loss, length of hospital stay and overall complications. This systematic review suggests no statistical difference in surgical and patient outcomes between robotic and conventional laparoscopic hysterectomy relating to OT, EBL, LOHS, overall complications, and survival.

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.

Robotic-assisted hysterectomy versus laparoscopic hysterectomy: Is it worth it?

Robotic-assisted hysterectomy versus laparoscopic hysterectomy: Is it worth it?

Validate robot-assisted total laparoscopic hysterectomy with four equally-spaced ports without an assistant port.

To evaluate the usefulness of robot-assisted total laparoscopic hysterectomy with four equally-spaced ports (RA-TLH/4e) without an assistant port. In RA-TLH/4e, four da Vinci ports were placed horizontally at a height of 4cm above the umbilicus with 8cm equal spacing. Poor development of the surgical field or difficult forceps manipulations were handled with the endoscope and forceps movement (port-hopping). Patient background, surgical outcomes, complications, port-hopping frequency were compared in three groups: RA-TLH/4e, RA-TLH with four unequally-spaced ports (RA-TLH/4u), and conventional RA-TLH with five ports (RA-TLH/5). There were no significant differences in patient background or surgical outcomes among the three groups except for age, preparation time, and hospital stay, and no cases of laparotomy conversion or serious complications. RA-TLH/4e had fewer port-hoppings than RA-TLH/4u. The minimum abdominal width showed a weak negative correlation with port-hopping frequency in RA-TLH/4u, but not in RA-TLH/4e. RA-TLH/4e allowed for a reduction in personnel and costs compared to RA-TLH/5. The equal placement of four ports allowed sufficient port spacing even for patients with narrow abdominal widths. In addition, the port-hopping technique was able to fully compensate for the lack of an assistant port. RA-TLH/4e is a highly useful technique that not only excels in safety but also reduces costs.

Vaginal Cuff Dehiscence after Robotic Hysterectomy in Endometrial Cancer vs. Non-Cancer Patients.

Vaginal cuff dehiscence (CD) after hysterectomy is a rare but serious complication of robotic-assisted laparoscopic total hysterectomy (RLTH). The authors of this study aimed to compare the incidence and risk factors of CD following RLTH among patients with and without endometrial cancer. This retrospective study included women aged 18 years or older who underwent RLTH by two surgeons at a single institution from 2013 to 2018. Patients with conversion to laparotomy, recent chemotherapy or radiation, or non-uterine malignancy were excluded. Data were abstracted from medical records. Of 950 patients meeting inclusion criteria, 50.7% had endometrial cancer. CD was reported in 2.5% of all patients. While adjusting for cancer status, age, sexual activity after surgery, distance from home to location of surgery, and time interval from surgery to loss to followup, obese patients were 25.1% less likely than non-obese patients to experience CD (62.5 vs. 37.5, p = 0.01). Surgeon A had a 2.8 times higher CD rate than surgeon B (70.8 vs. 29.2, p = 0.03). No other factors predicted CD. Endometrial cancer patients were not at greater risk of experiencing CD compared to non-cancer patients. Surgeon differences and body mass index (BMI) were associated with CD risk, with normal BMI patients at higher risk.

Novel workflow analysis of robot-assisted hysterectomy through objective performance indicators: a pilot study.

The curriculum for a da Vinci surgeon in gynecology requires special training before a surgeon performs their first independent case, but standardized, objective assessments of a trainee's workflow or skills learned during clinical cases are lacking. This pilot study presents a methodology to evaluate intraoperative surgeon behavior in hysterectomy cases through standardized surgical step segmentation paired with objective performance indicators (OPIs) calculated directly from robotic data streams. This method can provide individual case analysis in a truly objective capacity. Surgical data from six robot-assisted total laparoscopic hysterectomies (rTLH) performed by two experienced surgeons was collected prospectively using an Intuitive Data Recorder. Each rTLH video was annotated and segmented into specific, functional surgical steps based on the recorded video. Once annotated, OPIs were compared through workflow analysis and across surgeons during two critical surgical steps: colpotomy and vaginal cuff closure. Through visualization of the individual steps over time, we observe workflow consistencies and variabilities across individual surgeons of a similar experience level at the same hospital, creating unique surgeon behavior signatures across each surgical case. OPI differences across surgeons were observed for both the colpotomy and vaginal cuff closure steps, specifically reflecting camera movement, energy usage and clutching behaviors. Comparing colpotomy and vaginal cuff closure time needed for the step and the events of energy use were significantly different (p < 0.001). For the comparison between the two surgeons only the event count for camera movement during colpotomy showed significant differences (p = 0.03). This pilot study presents a novel methodology to analyze and compare individual rTLH procedures with truly objective measurements. Through collection of robotic data streams and standardized segmentation, OPI measurements for specific rTLH surgery steps can be reliably calculated and compared to those of other surgeons. This provides opportunity for critical standardization to the gynecology field, which can be integrated into individualized training plans in the future. However, more studies are needed to establish context surrounding these metrics in gynecology.

Pelvic floor and sexual function 3 years after hysterectomy - A prospective cohort study.

Long term effects after hysterectomy, such as a worsening of pelvic floor and sexual function, have been studied with diverse results. Therefore, we investigated the long-term effects of hysterectomy for benign indication on pelvic floor and sexual function as well as differences in outcome depending on mode of hysterectomy. In a prospective clinical cohort study, we included 260 women scheduled for hysterectomy who answered validated questionnaires; pelvic floor impact questionnaire (PFIQ-7), pelvic floor distress inventory (PFDI-20) and female sexual function index (FSFI). Participants were followed up to 3 years after surgery. Nonparametric statistics and mixed effect models were used in analyses of the data. After exclusions, 242 women remained in the study, with a response rate at the 3-year follow-up of 154/242 (63.6%) for all questionnaires. There was an improvement of pelvic floor function with a mean score of PFIQ-7 at baseline of 42.5 (SD 51.7) and at 3 years 22.7 (SD 49.4), (p < 0.001) and mean score of PFDI-20 at baseline was 69.6 (SD 51.1) and at 3 years 56.2 (SD 54.6), (p = 0.001). A deterioration of sexual function was seen among the sexually active women after 3 years with a mean score of FSFI at baseline 25.2 (SD 6.6) and after 3 years 21.6 (SD 10.1), (p < 0.001). However, this was not consistent with the unaltered sexual function for the whole cohort. No difference in pelvic floor or sexual function was detected when comparing robotic assisted laparoscopic hysterectomy, laparoscopic hysterectomy and abdominal hysterectomy. Three years after surgery robotic assisted laparoscopic hysterectomy, total laparoscopic hysterectomy and abdominal hysterectomy improve pelvic floor function to the same extent. Among the sexually active women, a decline of sexual function was seen after 3 years, not consistent with the entire cohort and independent of surgical methods. Whether this is a trend associated with aging or menopausal transition remains to be studied.

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.

The effect of sugammadex on postoperative urinary retention post-laparoscopic and robotic hysterectomy with and without concomitant procedures.

This study was aimed at determining the effect of sugammadex versus a combination of glycopyrrolate and neostigmine (GN) for neuromuscular reversal blockage on transient postoperative urinary retention (TPOUR) in patients undergoing a laparoscopic and robot-assisted laparoscopic hysterectomy. We conducted a retrospective cohort study in patients undergoing a laparoscopic or robotic hysterectomy between February 2017 and December 2021. Patients with and without concomitant procedures were included. Demographics and perioperative data were extracted from the patient's medical record. Before discharge, all patients were required to spontaneously void and have a post-void residual of less than 150ml. We identified 500 patients and 485 were included in the final analysis. We had 319 subjects who received sugammadex and 166 GN combination. Both groups had overall similar demographics and perioperative characteristics. Most patients had a conventional laparoscopy procedure (391 [82.5%]) compared with robotic (83 [17.5%]). Patients who received GN were significantly more likely to be discharged home with an indwelling catheter (odds ratio [OR], 1.82; 95% confidence interval [CI], 1.09-3.05). After adjusting for perioperative medications and sling implantation during the surgery a logistic regression model continued to demonstrate that patients who received GN had significantly higher odds of being discharged with a catheter (OR, 1.79; 95% CI, 1.03-3.12). Our findings suggest that sugammadex decreases the odds of TPOUR after laparoscopic hysterectomies with and without slings compared with the combination of GN. Additional prospective trials are required to confirm this finding.
