Risk Factors Asscociated with Hypokalemia during Postanesthesia Recovery and Its Impact on Outcomes in Gynecological Patients: A Propensity Score Matching Study

OBJECTIVE

This study aimed to explore the risk factors and outcomes of hypokalemia during the recovery period from anesthesia in the gynecological population.

METHODS

This retrospective cohort study included 208 patients who underwent gynecological surgery at our institution between January 2021 and March 2022. Data were collected for each patient, including demographics, disease status, surgical data, and clinical information. Preoperative bowel preparation, postoperative gastrointestinal function, and electrolyte levels were compared between the two groups using propensity score matching (PSM).

RESULTS

The incidence of hypokalemia (serum potassium level <3.5 mmol/L) during the recovery period from anesthesia was approximately 43.75%. After PSM, oral laxative use (96.4% vs. 82.4%, P=0.005), the number of general enemas (P=0.014), and the rate of ≥2 general enemas (92.9% vs. 77.8%, P=0.004) were identified as risk factors for hypokalemia, which was accompanied by decreased PaCO2 and hypocalcemia. There were no significant differences in postoperative gastrointestinal outcomes, such as the time to first flatus or feces, the I-FEED score (a scoring system was created to evaluate impaired postoperative gastrointestinal function), or postoperative recovery outcomes, between the hypokalemia group and the normal serum potassium group.

CONCLUSION

Hypokalemia during postanesthesia recovery period occurred in 43.75% of gynecological patients, which resulted from preoperative mechanical bowel preparation; however, it did not directly affect clinical outcomes, including postoperative gastrointestinal function, postoperative complications, and length of hospital stay.

First experience with the Hugo™ robot-assisted surgery system for endometriosis: A descriptive study

INTRODUCTION

The Medtronic Hugo™ Robot-assisted Surgery (RAS) system was recently approved for clinical use. We explored the safety and feasibility of this system for endometriosis surgery. The primary outcome was safe case completion without major surgical complications (Clavien-Dindo grade ≤2) and no conversion to open surgery or laparoscopy.

MATERIAL AND METHODS

Surgeries for endometriosis performed at the Department of Gynecology, Rigshospitalet, on the Medtronic Hugo™ RAS system were included. Two experienced robotic surgeons performed all surgeries with their usual robotic team. The variables included were patient demographics, peri- and postoperative data, complications and 30-day readmission rate. We used the IDEAL framework 1/2a for surgical innovation in this descriptive study.

RESULTS

The first 12 patients were included. All cases were completed without intraoperative complications or conversion. Four patients experienced Clavien-Dindo grade 1 postoperative complications. No patients were re-admitted within 30 days. Median docking time (17 minutes), console time (87.5 minutes), blood loss (40 mL) and length of hospital stay (1 day) were acceptable compared with previous literature.

CONCLUSIONS

In this pilot study, we found the Medtronic Hugo™ RAS system safe and feasible for robot-assisted surgery for endometriosis. The advent of new robotic systems is welcomed to accelerate the development of technology that will advance surgical care for patients across the globe.

Effect of opioid-free anesthesia on postoperative nausea and vomiting after gynecological surgery: a systematic review and meta-analysis

Background: Postoperative nausea and vomiting (PONV) is a common complication, that can reduce patient satisfaction and may lead to serious consequences, such as wound dehiscence. Many strategies have been proposed to prevent PONV; however, it remains common, especially in high-risk surgeries such as gynecological surgery. In recent years, opioid-free anesthesia has been widely studied because it minimizes adverse reactions of opioids, such as nausea, vomiting, and itching; however, conclusions have been inconsistent. Therefore, we conducted this meta-analysis to investigate the effects of opioid-free anesthesia on PONV in patients undergoing gynecological surgery. Methods: A systematic search of the PubMed, Web of Science, Cochrane Library, and Embase databases, from inception to 28 August 2023, was performed. Keywords and other free terms were used with Boolean operators (OR and, AND) to combine searches. This review was performed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Results: Six studies involving 514 patients who underwent gynecological surgery were included. The forest plot revealed that the incidence of PONV (risk ratio = 0.52; p < 0.00001) and consumption of postoperative antiemetics use (risk ratio = 0.64; p = 0.03) were significantly lower in the opioid-free anesthesia group. In addition, opioid-free anesthesia improved the quality of recovery (mean difference = 4.69; p < 0.0001). However, there were no significant differences in postoperative pain scores (mean difference = 0.05; p = 0.85), analgesic use (risk ratio = 1.09; p = 0.65), and the time of extubation (mean difference = -0.89; p = 0.09) between the opioid-free anesthesia and control groups. Conclusion: OFA reduces PONV and the use of antiemetic drugs. In addition, it improves the quality of postoperative recovery. However, OFA can not reduce the postoperative pain scores, analgesic use and the time of extubation. Due to the strength of the evidence, we cannot support OFA as an ideal anesthesia method in gynecological surgery, and the implementation of anesthesia strategies should be case-by-case.

Innovation in operative hysteroscopy: Use of Ellick bladder evacuator for tissue retrieval after hysteroscopic myomectomy using a resectoscope

The novel use of an Ellick bladder evacuator for tissue retrieval after operative hysteroscopy by electrosurgical resectoscope can reduce operative time, multiple additional scope reinsertions and possible complications.

Physicians' assessment of complications after gynecological surgery in Sweden: The GYNCOM survey

INTRODUCTION

Complications after gynecological surgery in Sweden are registered in the well-established Swedish National Quality Register of Gynecological Surgery, GynOp. The aim of this study was to analyze interrater reliability in assessing complications according to the methods in GynOp, and to explore physicians' perceptions of registering complications.

MATERIAL AND METHODS

A digital survey was sent to gynecologists and residents in gynecology in Sweden. Participating clinics were recruited through the Swedish network for national clinical studies in Obstetrics and Gynecology, SNAKS. Twenty fictional cases, intended to represent normal postoperative course, failure to cure, and varying degrees of complications, were developed by the research group. The clinical scenarios included abdominal and laparoscopic surgery of the uterus and adnexa, vaginal hysterectomies, as well as hysteroscopy. The respondents graded each case on the presence of a complication (yes/no). Type of complication, severity, and what action the complication required according to Clavien-Dindo was registered if a complication was acknowledged, according to the method in GynOp. Interrater reliability and the opinions of the respondents were presented descriptively. More than 80% of respondents making the same assessment was considered as agreement.

RESULTS

The response rate was 41%, with 104 responding physicians from 16 gynecological clinics. Type and severity of complication was considered relevant to register by 88% and 89% of respondents, respectively. Agreement on whether the case described a complication was >80% in 85% (17/20) of cases and agreement using the Clavien-Dindo classification was >90% in 80% (16/20) of cases. There was high agreement in assessments of classically severe complications, such as pulmonary embolism and ureteral damage, in both presence of complication and severity, as well as Clavien-Dindo (>90% for all methods). Cases with agreement <80% on whether the case described a complication were bordering between normal postoperative course and minor complication.

CONCLUSIONS

This study provides validation for the methods used to register complications after gynecological surgery according to the GynOp register, including the use of Clavien-Dindo in gynecology. However, the results indicate a need to define what should be considered symptoms inherent to each type of surgery.

Sociodemographic characteristics associated with indications for surgical menopause in women: a retrospective study

OBJECTIVE

The aim of this study was to evaluate the surgical menopause indications and sociodemographic characteristics of women.

METHODS

In this retrospective study, we analyzed the sociodemographic characteristics of women with indications for surgical menopause in 2010-2020. The R Version 4.1.1 (2021-08-10) software and logistic regression analysis were used to evaluate the data.

RESULTS

A total of 704 women's data were obtained in this study. Surgical menopause indications were found to stem from bleeding (46.0%), cancer (28.3%), cancer risk (18.9%), and other causes (6.8%). Surgical menopause indications originating from cancer were increased by 0.08 times (95%CI 0.01-0.68) due to smoking, 0.45 times (95%CI 0.23-0.88) due to regular drug use, and 0.36 times (95%CI 0.19-0.69) due to the presence of chronic disease (p<0.05).

CONCLUSION

More than half of the women with surgical menopause indications were between 41 and 46 years of age. Additionally, 54.9% of the women had a chronic disease. Therefore, it is recommended to plan preventive health services for morbidity and mortality risks that may develop due to surgical menopause.

Severe pelvic pain is associated with sexual abuse experienced during childhood and/or adolescence irrespective of the presence of endometriosis

STUDY QUESTION

Is endometriosis associated with childhood and/or adolescent sexual abuse?

SUMMARY ANSWER

Endometriosis is not associated with a history of sexual abuse, unlike the presence of severe pelvic pain.

WHAT IS KNOWN ALREADY

Several studies have highlighted a link between pelvic pain and sexual abuse during childhood/adolescence. Moreover, an inflammatory state has been described in patients with a history of childhood maltreatment. Given that inflammation and pelvic pain are two entities often encountered with endometriosis, several teams have investigated whether endometriosis is associated with abuse during childhood/adolescence. However, the results are conflicting, and the link between sexual abuse and the presence of endometriosis and/or pain is hard to disentangle.

STUDY DESIGN, SIZE, DURATION

A survey nested in a cohort study of women surgically explored for benign gynecological indications at our institution between January 2013 and January 2017. For each patient, a standardized questionnaire was completed during a face-to-face interview with the surgeon in the month preceding the surgery. Pelvic pain symptoms (dysmenorrhea, deep dyspareunia, non-cyclic chronic pelvic pain, and gastrointestinal or lower urinary tract symptoms) and their intensities were assessed with a 10 cm visual analog scale (VAS). Pain was considered to be severe when the VAS score was ≥7.

PARTICIPANTS/MATERIALS, SETTING, METHODS

A 52-question survey was sent in September of 2017 to evaluate abuses, especially sexual abuse during childhood and/or adolescence, and the psychological state during childhood and adolescence. The survey was structured to cover the following sections: (i) abuses and other life events during childhood and adolescence; (ii) puberty and body changes; (iii) onset of sexuality; and (iv) family relationships during childhood and adolescence. The patients were divided into groups according to whether or not they exhibited histologically proven endometriosis. Statistical analyses were conducted using univariate and multivariate logistic regression models.

MAIN RESULTS AND THE ROLE OF CHANCE

Two hundred and seventy-one patients answered all the questions of the survey: 168 with (endometriosis group) and 103 without endometriosis (control group). The mean ± SD overall population age was 32.2 ± 5.1 years. There were 136 (80.9%) and 48 (46.6%) women who experienced at least one severe pelvic pain symptom in the endometriosis and the control groups, respectively (P < 0.001). No differences were found between the two study groups regarding the following characteristics: (i) a history of sexual, physical, or emotional abuse; (ii) a history of abandonment or bereavement; (iii) the psychological state regarding puberty; and (iv) the family relationships. After multivariable analysis, we found no significant association between endometriosis and a history of sexual abuse during childhood and/or adolescence (P = 0.550). However, the presence of at least one severe pelvic pain symptom was independently associated with a history of sexual abuse (odds ratio = 3.6, 95% CI (1.2-10.4)).

LIMITATIONS, REASONS FOR CAUTION

Evaluation of the psychological state during childhood and/or adolescence can be subject to recall bias. In addition, selection bias is also a possibility given that some of the patients surveyed did not return the questionnaire.

WIDER IMPLICATIONS OF THE FINDINGS

Severe gynecological painful symptoms in women with or without histologically proven endometriosis may be linked to sexual abuse experienced during childhood and/or adolescence. Patient questioning about painful symptoms and abuses is important to provide comprehensive care to the patients, from a psychological to a somatic point of view.

The Beginner Laparoscopists Trends in the Learning Process of Laparoscopy for Adnexal Gynecological Pathologies-The Experience of Our Center

BACKGROUND

Laparoscopy for benign ovarian pathology is the appropriate surgical approach and it has many well-known advantages. Minimal invasive gynecological surgery increases the quality of life of the patient. The learning process of laparoscopy is difficult and requires many interventions to acquire manual skills. The objectives of the study were to assess the learning process of laparoscopy for adnexal pathology surgery performed by beginner laparoscopists.

MATERIALS AND METHODS

This study included three gynecological surgeons who were beginners in laparoscopy and who were named A, B, and C. We collected information about patients, diagnosis, surgical technique, and complications.

RESULTS

We have analyzed the data from 159 patients. The most frequent primary diagnosis was functional ovarian cyst, and the laparoscopic cystectomy was performed in 49.1% of interventions. The need to convert a laparoscopy into laparotomy was necessary in 1.3% of patients. There were no cases of reintervention, blood transfusion, or ureteral lesions. The duration of the surgical intervention varied statistically significantly according to patient's BMI and to the surgeon. After 20 laparoscopic interventions, a significant improvement was found in the time needed to perform ovarian cystectomy (operators A and B) and salpingectomy (operator C).

CONCLUSIONS

The process of learning laparoscopy is laborious and difficult. We found a significant decrease in operating time after a twenty laparoscopic interventions.

The anatomy of the uterine artery: A meta-analysis with implications for gynecological procedures

The uterine artery (UA) is an arterial branch of the internal iliac artery in women, usually arising from the anterior division of the internal iliac artery. However, due to the high variability in the anatomy of the UA, embolization of this vessel may be challenging. Therefore, the objective of this meta-analysis was to provide physicians with transparent data on the anatomy of the UA, using the available data in the literature. Databases such as PubMed, Scopus, Embase, Web of Science, and Google Scholar were searched to find all the relevant studies regarding the UA. A total of 16 articles met the required criteria. The UA was found to originate most frequently from the internal iliac artery as the pooled prevalence was set to be 61.72% (95% CI: 41.31%-80.31%). A pooled prevalence of the UA originating from the umbilical artery was established at 13.93% (95% CI: 2.76%-30.44%). A pooled prevalence of the UA originating from the inferior gluteal artery was set to be 5.22% (95% CI: 0.00%-15.44%). In conclusion, we believe that this is the most accurate and up-to-date study regarding the highly variable anatomy of the UA. The UA originates most frequently from the internal iliac artery (61.72%), however, other origins, such as from the umbilical artery (13.93%) or the inferior gluteal artery (5.22%) may occur. It is hoped that the results of the present meta-analysis will be a helpful tool for surgeons performing pelvic or gynecological surgeries.

Effect on music therapy on quality of recovery and postoperative pain after gynecological laparoscopy

BACKGROUND

Music therapy is safe, inexpensive, simple, and has relaxing properties for mental and physical capacities, as well as few side effects. Moreover, it improves patient satisfaction and reduces postoperative pain. Thus, we intended to evaluate the effect of music intervention on the quality of comprehensive recovery using quality of recovery 40 (QoR-40) survey in patients undergoing gynecological laparoscopic surgery.

METHODS

Patients were randomly assigned to music intervention group or control group: 41 patients each. After anesthetic induction, headphones were placed on the patients, and then classical music selected by an investigator was started in the music group with individual comfortable volume during surgery, while the player was not started in the control group. On postoperatively 1 day, the QoR-40 (5 categories: emotions, pain, physical comfort, support, and independence) survey was evaluated, while postoperative pain, nausea, and vomiting were assessed at 30 minutes and 3, 24, and 36 hours postoperatively.

RESULTS

Total QoR-40 score was statistically better in the music group, and among the 5 categories, the music group had a higher pain category score than the control group. The postoperative pain score was significantly lower in the music group at 36 hours postoperatively, although the requirement for rescue analgesics was similar in both groups. The incidence of postoperative nausea did not differ at any time point.

CONCLUSION

Intraoperative music intervention enhanced postoperative functional recovery and reduced postoperative pain in patients who underwent laparoscopic gynecological surgery.

Surgical complications and their impact for gynecological surgeons

OBJECTIVES

Major clinical incidents can impact the healthcare professionals involved. This is of particular relevance in surgery, with the operating room being a high-risk zone for complications; however, there is few available data on how surgeons may be affected. The current study examined the impact of surgical complications on surgeon traumatic stress levels, emotional state, job performance, and coping strategies.

METHODS

A questionnaire to evaluate the impact of surgical complications on surgeon traumatic stress levels, emotional state, and job performance was developed by our team and communicated via an online link to gynecological surgeons.

RESULTS

A total of 72 gynecologic surgeons completed the questionnaire. Five percent had a Peritraumatic Distress Inventory (PDI) score of ≥15, revealing a high stress level, and 12% had an Impact of Event Scale-Revised (IES-R) score of ≥36, indicating acute traumatic stress. Our results show that following surgical incidents, surgeons receive support primarily from another surgical team member and that surgical practice may be impacted, leading in some cases to detrimental effects on patient care, notably reduced radicality in some surgical procedures.

CONCLUSION

Surgeons may experience acute traumatic stress after serious surgical complications. Increased awareness of the negative consequences on surgeon emotional well-being is required, as well as improved access to support mechanisms. The study was approved by local ethics committee (IRB00013412, "CHU de Clermont Ferrand IRB #1," institutional review board number 2022-CF004).

Multi-Institutional Trends in Gynecological Robotic Surgery in India: A Real-World Scenario

Background Robot-assisted laparoscopic surgery in gynecology has grown exponentially compared to laparoscopic surgery. The probable reasons for the increased uptake of robotics are a shorter learning curve, three-dimensional vision, and increased dexterity compared to laparoscopic surgery, and precise surgery as compared to open surgery. This study compares the time trends of various parameters in robotic gynecological surgery in India over a decade. Material and methods In India, a retrospective analysis of all robot-assisted laparoscopic surgery for gynecologic diseases in five tertiary care hospitals was conducted between July 2011 and June 2021. Data were collected regarding demographic profiles, clinical and disease characteristics, and indications for surgery. Details related to surgery were collected, such as the number of ports, console and docking time, the procedure performed, total operative time, average blood loss, blood transfusion, and length of hospital stay. All the parameters collected were grouped into five years, and a comparison was made between the first five years (2011-2015) and the second five years (2016-2021). Statistical analysis, including descriptive statistics and trend analysis, was performed. Results During the 10 years, the total number of cases included was 1,501, out of which 764 were benign cases and 737 were pre-malignant/malignant cases. The common indications were uterine leiomyoma (31.2%) and carcinoma endometrium (28%). The mean age for benign cases was significantly lower than that for malignant cases (40.84 years and 55.42 years, respectively). Mean blood loss was significantly lower for benign indications (97.48 mL) than for oncological surgery (184.67 mL) and needed fewer transfusions. The mean length of stay (LOS) for benign (2.07 days) and malignant/ pre-malignant cases (2.32 days) and the mean BMI for benign (28.40) and for oncological patients (28.47) were similar in both groups. The docking time reduced significantly in the last five years. Conclusion The current retrospective study demonstrates an increasing uptake of robotic technology in gynecological surgery in India. Of the total cohort of cases, 70.9% of patients underwent gynecological robotic surgery in the last five years. A burst of adaptability happened for malignant cases in 2017 and benign cases in 2018, probably due to the increased availability of robotic platforms and improved awareness of technology and training among medical professionals. The number of cases has grown exponentially over the last five years in both benign and malignant/ pre-malignant scenarios; however, there has been a downward trend in the robotic surgery performed in the previous couple of years due to the uncertainty of the COVID pandemic.

Risk Factors for Adhesion-Related Readmission and Abdominal Reoperation after Gynecological Surgery: A Nationwide Cohort Study

More than half of women in developed countries undergo surgery during their lifetime, putting them at risk of adhesion-related complications. Adhesion-related complications include small bowel obstruction, chronic (pelvic) pain, subfertility, and complications associated with adhesiolysis during reoperation. The aim of this study is to predict the risk for adhesion-related readmission and reoperation after gynecological surgery. A Scottish nationwide retrospective cohort study was conducted including all women undergoing a gynecological procedure as their initial abdominal or pelvic operation between 1 June 2009 and 30 June 2011, with a five-year follow-up. Prediction models for two- and five-year risk of adhesion-related readmission and reoperation were constructed and visualized using nomograms. To evaluate the reliability of the created prediction model, internal cross-validation was performed using bootstrap methods. During the study period, 18,452 women were operated on, and 2719 (14.7%) of them were readmitted for reasons possibly related to adhesions. A total of 2679 (14.5%) women underwent reoperation. Risk factors for adhesion-related readmission were younger age, malignancy as indication, intra-abdominal infection, previous radiotherapy, application of a mesh, and concomitant inflammatory bowel disease. Transvaginal surgery was associated with a lower risk of adhesion-related complications as compared to laparoscopic or open surgeries. The prediction model for both readmissions and reoperations had moderate predictive reliability (c-statistics 0.711 and 0.651). This study identified risk factors for adhesion-related morbidity. The constructed prediction models can guide the targeted use of adhesion prevention methods and preoperative patient information in decision-making.

Surgical Site Infection in Obstetric and Gynecological Surgeries: A Prospective Observational Study

Introduction An infection at an incisional site that develops within 30 days after surgery, or within a year if a prosthetic is implanted, is referred to as a surgical site infection (SSI). They are mainly caused by exogenous and/or endogenous microbes that penetrate the surgical site during surgery (primary infection) or after the procedure (secondary infection). The prevention of SSI should be the ultimate goal of the surgery team and hospital administration. Methodology The prospective observational study of SSI consisted of 920 patients who were admitted and underwent surgery between April 2021 and September 2022. After a complete examination, a detailed proforma for the collection of data pertaining to patients in this study was prepared, and patients were included as per the inclusion and exclusion criteria. Results The study demonstrated significant results in terms of the association of body mass index (BMI), hemoglobin, and blood sugar level with the SSI status (p<0.05) and nonsignificant results in terms of emergency/elective surgery, type of surgery, and type of incision (p>0.05). Conclusion The overall rate of SSI was 9.2% in the present study. The major reasons involved are inadequate infrastructure facilities, different antibiotics policies, and non-uniform pre-, intra-, and post-operative measures that add woes and result in an increased incidence of SSI. In the present study that was undertaken at a teaching and tertiary care center, the SSI incidence is comparatively lower, but with the implementation of correct knowledge and technique, the rate can further be reduced to a large extent.

Enhanced recovery after surgery program alleviates neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio in patients undergoing gynecological surgery

Background

To evaluate the efficacy of the enhanced recovery after surgery (ERAS) programs on the systemic inflammatory response (SIR) of patients following gynecological surgery, a randomized controlled trial was performed to compare the ERAS programs with the conventional perioperative care programs. Furthermore, novel SIR markers could be identified to evaluate the ERAS programs of gynecological surgery.

Methods

Patients undergoing gynecological surgery were randomly allocated to either the ERAS group or the conventional group. The correlations between the elements of ERAS protocols and SIR markers following gynecological surgery were evaluated.

Results

A total of 340 patients who underwent gynecological surgery were enrolled (ERAS = 170; conventional = 170). First, we identified whether the ERAS programs after gynecological surgery reduced the perioperative difference between neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR). Interestingly, first flatus time postoperatively, visual analog scale (VAS) score of patients was positively correlated with the perioperative difference NLR or PLR. Moreover, we discovered that the perioperative difference NLR or PLR was correlated with elements of ERAS protocol, including first sips of water, first semifluid diet postoperatively, pelvic drain duration, and out-of-bed time of patients.

Conclusion

We originally reveal that certain elements of ERAS programs alleviated SIR to operation. The implementation of ERAS programs enhances postoperative recovery after gynecological surgery via improving system inflammatory status. NLR or PLR could be the novel and inexpensive marker to assess ERAS programs in gynecological surgery.Clinical trial registration:ClinicalTrials.gov, identifier, NCT03629626.

Pure uterine lipoma - a paradoxical rarity

Pure uterine lipomas are extremely rare benign uterine tumors. This paper presents the case of a 68-year-old patient with symptomatic leiomyoma-like fundus formation on ultrasound. A hysterectomy was performed with anterior vaginal plastic surgery as a treatment option for concomitant cystocele grade II. Histological diagnosis of pure uterine lipoma with S-100 positive immunohistochemical staining was confirmed. This case shows us that uterine lipoma clinically and diagnostically mimics myoma very well. We believe that surgery as a therapeutical approach is justified in symptomatic patients.

Enhanced recovery after gynecological surgery: A meta-analysis of randomized controlled trials

Enhanced recovery after surgery protocol is a multidisciplinary and multimodal approach designed to improve perioperative outcomes for patients. This meta-analysis aimed to identify and elaborate on the efficacy of this protocol in women undergoing gynecologic surgery. Four databases were searched for randomized controlled trials from inception to December 2021. A total of 14 studies met the inclusion criteria and were analyzed. There was a significant reduction in the length of stay, the time to first flatus and first defecation, complications, and readmission rates in patients undergoing enhanced recovery after surgery when compared to routine care. The rate of discharge on the first postoperative day significantly increased in patients from the enhanced recovery group. There was no significant difference in the surgery time and blood loss. In conclusion, the enhanced recovery after surgery protocol might have a positive effect on patients undergoing gynecologic surgery. However, there is still heterogeneity between the included studies, and we need more research to draw reliable conclusions that enhanced recovery after surgery is favorable.

Progression Free Survival, Overall Survival, and Relapse Rate in Endometrioid Ovarian Cancer and Synchronous Endometrial-Ovarian Endometrioid Cancer (SEO-EC): Results from a Large Retrospective Analysis

Background and Objectives: We aimed to evaluate Progression Free Survival (PFS), Overall Survival (OS), and relapse rate in women affected by endometrioid ovarian cancer and synchronous endometrial-ovarian endometrioid cancer (SEO-EC). As secondary outcome, we assessed whether systematic pelvic and para-aortic lymphadenectomy could be considered a determinant of relapse rate in this population. Materials and Methods: We performed a retrospective analysis of women with diagnosis of endometrioid ovarian cancer or SEO-EC between January 2010 to September 2020, and calculated PFS, OS and relapse rate. Results: In almost all the patients (97.6%) who underwent systematic pelvic and para-aortic lymphadenectomy, there were no lymph node metastases confirmed by histology. We did not find a significant difference (p = 0.6570) for the rate of relapse in the group of women who underwent systematic pelvic and para-aortic lymphadenectomy (4/42; 9.5%) compared with the group of women who did not undergo the same procedure (1/21; 4.8%). During a median follow-up was 23 months, both PFS and OS were excellent. Conclusions: Women affected by early-stage low-grade endometrioid cancer and SEO-EC without apparent lymph node involvement at pre-operative imaging showed a very low rate of lymph node metastasis and similar relapse rate with or without lymphadenectomy.

Uterine fibroid: a socially malignant illness in Haiti

This qualitative study documented the effects of uterine fibroids on the suffering of women in Haiti. It makes a unique contribution by re-socializing this disease, by making visible the social inequalities and what is at stake for the women, for their families, and for healthcare delivery. Uterine fibroid is a benign tumor of the uterus, common in gynecology, but profoundly malignant in how it affects women's lives. Little has been reported on their lived experiences. Haiti has historical, social, and economic factors that hinder the search for treatment. The study explores how and why patients seek surgical care for uterine fibroids at Mirebalais University Hospital. Seventeen in-depth interviews with patients and seven accompanying family members were conducted and recorded in Creole and translated into English, along with participant observations in two patients' homes. Content and narrative analysis were done iteratively, and the processual ethnographic method was used to relate our findings to Haitian history, to the context of the study, and to future implications. The women's experience of accompaniment, their suffering in their pèlerinage (care-seeking journey), and the troubling social impact of uterine fibroids make it a socially malignant illness. The study shows that it is critical to address the suffering of women afflicted with uterine fibroids by strengthening the Haitian health system, improving economic advantages, and establishing ways for them to gain access to social goods and participate in community activities.

Introducing the New Surgical Robot HUGO™ RAS: System Description and Docking Settings for Gynecological Surgery

This study provides a detailed description of the new HUGO™ RAS System and suggests docking settings for gynecological surgery. The system is composed of an "open" surgical console with an HD-3D passive display, a system tower, and four arm carts. Each arm has an extremely wide range of adaptability resulting from the numerous joints. The human cadaver labs were performed at the ORSI Academy between August and December 2021. All procedures were performed by two surgical teams, each composed of a high-volume surgeon experienced in robotic surgery, gynecologic oncology, and pelvic sidewall surgery, and one bedside assistant. Three main gynecological surgical scenarios were identified: standard pelvic surgery, pelvic sidewall surgery, and para-aortic/upper abdominal surgery. Concerning the port placement, the chosen options were called "straight" and "bridge"; instead, the so-called "compact" and "butterfly" configurations were identified for the arm cart positioning. Four cadavers were used to perform total hysterectomy, radical hysterectomy, pelvic exenteration, pelvic and para-aortic lymphadenectomy, and omentectomy. We performed several tests, identifying the best system configurations to draw the proper efficiency from the flexibility of the system in all gynecological surgical scenarios. The straight port placement seems to be adequate for standard pelvic surgery. The bridge trocar position is best to reach the deeper and lateral anatomical regions of the female pelvis. The compact and butterfly arm cart allocations are adequate for both straight and bridge port placement. When deep pelvic surgery was performed, the bedside assistant became more proficient by working with a standard laparoscopic instrument from an ancillary port placed in the left iliac fossa. The arm carts needed to be moved in an open manner, like for the proposed butterfly configuration. On the contrary, the compact disposition left enough space to assist from Palmer's point port. Several basic and advanced gynecological surgical procedures were performed and completed successfully without encountering any technical or surgical issue, the results obtained were judged sufficient to proceed with the clinical experience in daily practice. The HUGO™ RAS system is flexible and highly performative in various surgical scenarios.

Effects of subanesthesia dose S-ketamine induction on postoperative psychiatric complications after gynecological surgery

Ketamine may become an important drug for multimodal analgesia regime again because of its strong analgesic effects and retaining the advantage of spontaneous breathing. The present study was designed to explore the influences of different dosages of S-ketamine anesthesia induction regimes on psychiatric complications and postoperative prognosis in patients undergoing gynecological operations. In this prospective, triple-blinded, randomized, controlled study, patients undergoing elective gynecological surgery were randomized to one of three treatment groups: low-dose S-ketamine (LDSK) group (a 0.3 mg/kg bolus for anesthesia induction), minimal-dose S-ketamine (MDSK) group (a 0.2 mg/kg bolus for anesthesia induction), and placebo (CON) group (a saline bolus for anesthesia induction). The main outcome measures were as follows: intraoperative vital signs, extubation time, anesthesia recovery time and postanesthesia care unit (PACU) stay duration, incidence of psychiatric complications, Ramsay sedation scale (RSS) 1, 2, 24, and 48 h, postoperatively, and overall prognosis. One hundred and eighty female participants were finally included in this study from April 2021 to December 2021. Significant differences were not observed in age, height, weight, American Society of Anesthesiologists physical status classification, or history of mental illness between the groups. No statistically significant differences were discovered with regard to intraoperative vital signs, extubation time and PACU stay duration, incidence of psychiatric complications, and RSS scores at 1, 2, 24, and 48 h postoperatively in the three groups. However, the visual analog scale (VAS) scores of the CON group at 10 min after extubation and at the time point leaving PACU were much higher than that of the LDSK and MDSK groups. The VAS scores at 48 h after surgery in the MDSK group were also lower than that of the CON group and the CON group had received more analgesic drug treatment in the surgical wards consequently. Postoperative nausea and vomiting (PONV) occurrence at 24 and 48 h, postoperatively, increased sharply in the CON group than in the other two experimental groups, which led to an increase in the use of postoperative antiemetic drugs in this group. According to the postoperative satisfaction survey, patients in the CON group had lower medical satisfaction. Our data demonstrate that a small dosage of S-ketamine anesthesia induction can reduce postoperative pain and the incidence of PONV without increasing hemodynamic fluctuations or psychiatric complications.

Skin preparation for prevention of surgical site infection after obstetrics and gynecological abdominal surgery: A quality improvement project

BACKGROUND

One of the most common causes of postoperative morbidity is postoperative surgical site infection (SSI). Healthcare-associated infection is a subject of great concern in healthcare services. The goal of the present study is to estimate the relative effectiveness of skin preparation solution chlorhexidine scrub followed by povidone-iodine painting in the prevention of SSIs after caesarean delivery and abdominal gynecological surgery.

MATERIAL AND METHODS

This is a 1-year randomized prospective research done at a tertiary care institution in western Rajasthan. Women who underwent caesarean and gynecological operations were randomly assigned to one of two groups. Enrolled patients were randomly assigned to have the surgical site painted with 10% povidone-iodine or a chlorhexidine-alcohol preparatory scrub followed by povidone-iodine paint. According to the Centres for Disease Control and Prevention criteria, the outcomes were any SSI occurring within a week or during the 30-day follow-up period following the operation, including any superficial or deep SSI.

RESULTS

A total of 251 patients were randomly assigned to two groups. Group A (povidone-iodine paint) received 121 patients, whereas Group B (chlorhexidine scrub + povidone-iodine paint) received 129 cases. The overall SSI rate in the present study was 8.76%. The SSI rate was lower in Group B (chlorhexidine scrub + povidone-iodine paint) as compared to Group A (povidone-iodine paint only) (5.4% vs. 12.4%; p = 0.04).

CONCLUSION

This study highlighted that chlorhexidine-alcohol scrubbing followed by povidone-iodine painting provides superior skin antisepsis in comparison to povidone-iodine painting alone.

Ovarian Torsion Occurring Nine Days after Ipsilateral Dermoid Cystectomy

Ovarian torsion (OT) is a gynecological emergency that requires prompt treatment and management. It is associated with risk factors such as ovarian cysts and prior pelvic surgery. Diagnosis and treatment require surgery to examine the adnexa, correct the torsion, and determine if cystectomy or oophorectomy are required. We reported the case of a 34-year-old woman who presented 9 days after a dermoid cystectomy with sudden onset abdominal pain. An ultrasound showed abnormal blood flow to the ovary. She then underwent a repeat laparoscopy revealing a necrotic and twisted ovary on the same side that had a cystectomy. The surgeons proceeded with a right oophorectomy. Following surgery, the patient reported no concerns with no ongoing bleeding or pain. OT can present in the short-term postoperatively to an ovarian cystectomy, likely as a result of mechanical forces secondary to structural changes of the ovary. The role for prophylaxis against OT is unclear in those with significant risk factors for torsion.

Effects of modified multimodal analgesia on postoperative pain, sedation, and prognosis of gynecological patients

Patient-controlled intravenous analgesia is one of the most common pain relief methods in  the postoperative period, but its adverse reactions remain high. This study aimed to explore the role of improved combined analgesia methods in pain, sedation, postoperative nausea, and vomiting (PONV) in patients undergoing gynecological surgeries. This study was a prospective, randomized, double-blind controlled study. A study population of 72 patients undergoing gynecological surgery were randomly assigned to either the TAPB + S group or the TAPB + N group. All patients in both groups underwent a transversus abdominis plane block (TAPB) after induction of anesthesia. The TAPB + S group received a continuous intravenous infusion (2 ml/h) of sufentanil (1 μg/kg) plus metoclopramide (30 mg) through 100 ml elastomeric pumps postoperatively. The TAPB + N group received a continuous intravenous infusion (2 ml/h) of nalbuphine hydrochloride (1 mg/kg) plus metoclopramide (30 mg) postoperatively. The main outcome measures were as follows: postoperative pain intensity, Ramsay sedation score (RSS) after surgery, PONV occurrence rate, and rescue analgesics. The RSS of the TAPB + S group was significantly higher than that of the TAPB + N group at 2, 4, and 6 h after the operation. However, the visual analog scale score of the TAPB + S group was much higher than that of the TAPB + N group. No significant differences were found between the two groups in terms of consumption of opioids and other narcotic drugs at 2, 4, 6, 24, and 48 h after the operation. No statistically significant differences were found with respect to PONV and other adverse events in both groups. Taken together, our data indicate that the TAPB + N program can provide better postoperative analgesia and also reduce the use of strong opioids. The more optimized scheme of perioperative analgesia still needs to be researched further.

Near-Infrared Imaging With Indocyanine Green for the Treatment of Endometriosis: Results From the Gre-Endo Trial

Introduction

A current challenge for endometriosis surgery is to correctly identify the localizations of disease, especially when small or hidden (occult endometriosis), and to exactly define their real extension. The use of near-infrared radiation imaging (NIR) after injection of indocyanine green (ICG) represents one of the most encouraging method. The aim of this study is to assess the diagnostic value of NIR-ICG imaging in the surgical treatment of endometriosis compared with the standard of treatment.

Material and Methods

The Gre-Endo trial is a prospective, single-arm study (NCT03332004). After exploring the operatory field using the white light (WL) mode, patients were injected with ICG and then observed in NIR mode. All suspected areas were classified and chronicled according to lesions visualized only in WL, NIR-ICG, or in the combination of both. Lesion not visualized in WL was considered as suspect occult lesion (s-OcL). In addition, a random control biopsy from an apparent negative peritoneum visualized in WL and NIR-ICG imaging was taken for all patients (control cases). All lesions removed were considered “suspect endometriosis” until pathology.

Results

Fifty-one patients were enrolled between January 2016 and October 2019. A total of 240 suspected lesions have been identified with both methods (WL + NIR-ICG). Two hundred and seven (86.2%) lesions out of the overall 240 were visualized with WL imaging, and 200 were confirmed to be pathologic (true positive for WL). The remaining 33/240 (13.75%) (false negative for WL) lesions were identified only with NIR-ICG imaging and collected as s-OcL. All 33 s-OcLs removed were confirmed to be pathologic (c-OcL = 100%). NIR-ICG vision showed PPV of 98.5%, NPV of 87.1%, Se of 87%, and Sp of 98.5%, confirming that this kind of imaging is an excellent diagnostic and screening test (p = 0.001 and p = 0.835, according to McNemar’s and Cohen’s kappa tests, respectively).

Conclusions

The use of NIR-ICG vision alone and combined with WL showed good results in intraoperative detection rate and fluorescence-guided surgery of endometriosis. Furthermore, NIR-ICG allowed surgeons to remove occult lesions that otherwise would remain, leading to possible greater postoperative pain and a higher risk of persistence and relapse.

Endobag use in laparoscopic gynecological surgeries: a systematic review

PURPOSE

The purpose of this systematic review was to assess the characteristics of endobags present in the market, the weight of specimen removed, complications of the operations and time required for in-bag morcellation in women undergoing laparoscopic gynecologic surgeries.

MATERIAL AND METHODS

We performed a systematic review, including prospective and retrospective studies, with or without randomized allocation of the patients, using endobags in laparoscopic gynecologic surgeries. We extracted data about study design, type and price of bag used, type of surgical procedure, specimen weight, mean time for morcellation and for total surgical procedure, complications.

RESULTS

We included 11 studies, including a total of 1160 patients, in which the investigators used MorSafe, Endocatch II autosuture, More-Cell-Safe, Endocatch, EcoSac and LapBag. A wide range of specimens were morcellated with the largest successfully morcellated specimen weighing 2314 gr. Only half of the studies comparing uncontained and contained morcellation found a significant increase of total operative time. Finally, the number of complications was not increased when endobag was used.

CONCLUSION

According to our systematic review, in-bag (contained) morcellation can be considered as a safe and unexpensive option, associated with a very low number of complications, even with large specimens.

Application of Single-Port Laparoscopic Surgery in Myomectomy

Research Question

The use of a power morcellator in laparoscopic myomectomy is a controversial topic. The application of single-port laparoscopy solves this problem, but its safety, efficacy and prognosis are also challenges. The purpose of this study was to compare the clinical application of single-port laparoscopy and traditional three-port laparoscopy in myomectomy.

Design

This is a retrospective review of a total of 120 patients who underwent single-port laparoscopic myomectomy (n=60) or traditional three-port laparoscopic myomectomy (n=60), performed between January 2019 to December 2020. The operation time, intraoperative blood loss, specimen removal time, hemoglobin change after operation, postoperative ambulation time, first exhaust time after surgery, the length of hospital stay, pain score on the day, the first day after operation and the satisfaction of abdominal wall scar were evaluated for the surgical outcomes.

Results

Compared with the traditional three-port laparoscopic group, the specimen removal time, postoperative ambulation time, first exhaust time after surgery, the length of hospital stay were all shorter, the satisfaction of abdominal wall scar were higher in single-port laparoscopic group. The duration of surgery was longer in single-port laparoscopic group significantly. The differences were statistically significant (P<0.05). The intraoperative blood loss, hemoglobin change after operation, pain score on the day of operation and the first day after operation of the two groups had no differences (P>0.05).

Conclusions

The clinical effect of single-port laparoscopic myomectomy is satisfactory and can be popularized in clinic.

Vaginal NOTES surgery in patients with prior hysterectomy: A first case series

This is a first feasibility on vaginal natural orifice transluminal endoscopic surgery (vNOTES) in patients with prior hysterectomy. Our aim was to gain initial experience on performing vNOTES surgery on prior hysterectomy cases, whereby the main concern is that pelvic adhesions may impede safe transvaginal access. Between January 2017 and February 2020, a single surgeon (J.B.) performed vNOTES surgery on nine patients with a history of hysterectomy. Conventional laparoscopic instruments were inserted transvaginally through a vNOTES port. No abdominal incisions were made. Patient data and perioperative data were analyzed. Mean operating time was 38 minutes and there were no operative complications. Postoperative pain scores were low. The mean size of the adnexal cysts that were removed was 26 mm. In this study, vNOTES surgery was successfully performed in nine patients with prior hysterectomy. Following the IDEAL principles, it is important to report on our initial findings of this IDEAL stage 1 study. The results warrant further investigation in IDEAL stage 2 studies but do not validate the widespread use of this approach.

Comparing Time to Diagnosis and Treatment of Patients with Ruptured Ectopic Pregnancy Based on Type of Ultrasound Performed: A Retrospective Inquiry

BACKGROUND

Hemorrhage from ruptured ectopic pregnancy is the leading cause of first trimester mortality in North America.

OBJECTIVES

Our objective was to compare patients with a ruptured ectopic pregnancy who had an emergency department (ED) point-of-care ultrasound (PoCUS) with those who received a radiology department-performed ultrasound (RADUS). Four time intervals were measured: ED arrival to ultrasound interpretation, obstetric consultation, operating room (OR) arrival, and ultrasound interpretation to OR arrival.

METHODS

This was a retrospective cohort study of patients with ruptured ectopic pregnancy seen between February 2012 and September 2018 at an urban tertiary care hospital. Patients who received an ultrasound in the ED, went directly to the OR, and had confirmed rupture were included.

RESULTS

Of 262 patients diagnosed with ectopic pregnancy during the study period, 36 (14%) were ruptured and 32 were enrolled. Comparing times between PoCUS (n = 10) and RADUS (n = 22) groups, the mean time from ED arrival to ultrasound interpretation was 15 vs. 138 min (difference 123, 95% confidence interval [CI] 88-158), from ED arrival to obstetric consultation was 35 vs. 150 min (difference 115, 95% CI 59-171), from ED arrival to OR arrival was 160 vs. 381 min (difference 222, 95% CI 124-320), and from ultrasound interpretation to OR arrival was 145 vs. 243 min (difference 98, 95% CI 12-184).

CONCLUSION

ED patients with a ruptured ectopic pregnancy who received a PoCUS first had shorter times to diagnosis, obstetric consultation, and OR arrival compared with those who received RADUS.

Early and Standard Urinary Catheter Removal After Gynecological Surgery for Benign Lesions: A Quasi-Experimental Study

Patients undergoing gynecological surgery commonly receive indwelling transurethral Foley catheters, however duration of catheterization is associated with risk of urinary tract infections and other adverse effects. Early removal of catheters is encouraged, however optimal timing postsurgery remains unclear. This quasi-experimental study compared outcomes for women after removal of a Foley catheter at two different times following benign gynecological surgery. Participants received either early catheter removal, within 6 hours of surgery (n = 38) or standard catheter removal, within 12 to 24 hours of surgery (n = 45). There were no significant differences in outcomes for discomfort scores or re-catheterization rates between groups. However, the early removal group had a significantly shorter time to first ambulation and shorter hospital stays. Early removal of Foley catheters in patients who underwent gynecological surgery did not increase adverse events. Early removal of catheters after gynecological surgery may decrease re-catheterization rates and increase patient satisfaction.

The effect of Plan-Do-Check-Act cycle nursing management of gynecological surgery: a systematic review and meta-analysis

BACKGROUND

The Plan-Do-Check-Act cycle (PDCA) (also known as the Daiming cycle) is widely used in surgical management and can standardize nursing management and improve nursing quality. This meta-analysis evaluated the application of the PDCA cycle during nursing management following gynecological surgery.

METHODS

PubMed, Web of Science, Embase, CNKI, Wanfang, and other databases were searched for studies on applying the PDCA cycle in nursing management following gynecological and obstetric surgery. Articles published between 2013 to 2020 in English and Chinese were included. The obtained data are subjected to meta-analysis using Stata16.0 analysis software. Reported outcomes included: satisfaction with care, nursing quality evaluation, and assessments using the Self-Rating Anxiety Scale (SAS) and Self-Rating Depression Scale (SDS).

RESULTS

A total of 14 articles were included, with a total of 1,629 participants. Meta-analysis showed that satisfaction with gynecological surgery nursing using PDCA cycle management in the intervention groups was higher than in the control groups, OR =6.57 (95% CI, 4.01, 10.76), P<0.001. The perception of nursing quality was higher in the intervention groups than in the control groups, SMD =4.98 (95% CI, 3.32, 6.64, P<0.001. SAS scores of the intervention groups were lower than that of the control groups, SMD =-2.22 (95% CI, -2.80, -1.65), P<0.001. SDS scores of the intervention groups were lower than that of the control groups, SMD =-2.37 (95% CI, -3.15, -1.60), P<0.001.

DISCUSSION

The application of PDCA cycle nursing management for gynecological surgery can significantly improve patients' satisfaction with nursing, including the quality of nursing. At the same time, it can effectively reduce the anxiety and depression of surgical patients, which benefits the surgery process. Given these benefits, it has a high likelihood of being incorporated into clinical practice.

Effects of Surgical Delay Due to COVID-19 on Women Requiring Emergency Gynaecological Surgery

In response to the coronavirus-19 (COVID-19) pandemic, the McGill University Health Centre introduced protocols to protect health care workers during emergency surgeries. These included waiting for a COVID-19 test result or waiting 20 minutes after aerosol-inducing procedures before proceeding with surgery. The following brief communication describes the impact of surgical delay on the outcomes of 3 emergency gynaecologic procedures: dilatation and curettage, laparoscopic salpingectomy, and laparoscopic cystectomy and detorsion. Our results show that delays associated with COVID-19 protocols did not negatively impact patients undergoing these surgeries.

Robotic Natural Orifice Transluminal Endoscopic Surgery Hysterectomy and Salpingo-Oophorectomy in a Porcine Model

Purpose. The emergence of robotic-assisted surgical techniques has gained significant indications in terms of reduced trauma, shortened recovery, and higher patients' satisfaction. However, limitations by present surgical robotic systems used in natural orifice transluminal endoscopic surgery (NOTES) gynecology still exists, such as arm collisions, countertraction, instrument dexterity, and, in particular, space confinement due to the narrow pelvic anatomy. The current study evaluated the use of a miniaturized single-site surgical robotic system and its feasibility in performing robotic NOTES gynecological procedures using a live porcine animal model. Methods. Using a transrectal approach, the fully internalized robotic arms were deployed in a reverse configuration to access the lower pelvic cavity of the animals to perform NOTES gynecological procedures. Results. Robotic-assisted transrectal gynecological procedures were successfully performed using the new robotic system. A hemi-hysterectomy with unilateral salpingo-oophorectomy was completed in the first animal and a total hysterectomy with bilateral salpingo-oophorectomy in the second animal with an average docking time of 22.5 minutes and console time of 63 minutes and 58 minutes, respectively. The overall blood loss for each procedure was estimated to be <20 mL per animal with no intraoperative complications. Conclusions. The reverse configuration of the miniaturized surgical robotic system has demonstrated its capability to provide a potential solution to maintain clear visualization of the surgical field, optimal triangulation, and dexterity robotic NOTES gynecological procedures within the deep confined space of the pelvic cavity.

Transdermal Buprenorphine for Acute Pain in the Clinical Setting: A Narrative Review

Transdermal buprenorphine is indicated for chronic pain management, but as its role in the clinical management of acute pain is less clear, this narrative review examines studies of the patch for acute pain, mainly in the postoperative setting. Although perhaps better known for its role in opioid rehabilitation programs, buprenorphine is also an effective analgesic that is a Schedule III controlled substance. Although buprenorphine is a partial agonist at the μ-opioid receptor, it is erroneous to think of the agent as a partial analgesic; it has full analgesic efficacy and unique attributes among opioids, such as a ceiling for respiratory depression and low “drug likeability” among those who take opioids for recreational purposes. Transdermal buprenorphine has been most thoroughly studied for acute pain control in postoperative patients. Postoperative pain follows a distinct and predictable trajectory depending on the type of surgery and patient characteristics. Overall, when the patch is applied prior to surgery and left in place for the prescribed seven days, it was associated with reduced postoperative pain, lower consumption of other analgesics, and patient satisfaction. Transdermal buprenorphine has been evaluated in clinical studies of patients undergoing gynecological surgery, hip fracture surgery, knee or hip arthroscopy/arthroplasty, shoulder surgery, and spinal surgery. Transdermal buprenorphine may also be appropriate pain medication for controlling pain during postsurgical orthopedic rehabilitation programs. Transdermal buprenorphine may result in typical opioid-associated side effects but with less frequency than other opioids. Despite clinical reservations about transdermal buprenorphine and its potential role in acute pain management in the clinical setting, clinical acceptance may be hampered by the fact that it is off-label and buprenorphine is better known as an opioid maintenance agent rather than an analgesic.

Patient-reported outcomes after surgery among patients with gynecological diseases in Japan

PURPOSE

This study aimed to investigate quality of life (QOL) and psychological distress based on patient-reported outcomes (PROs) after surgery among patients with gynecological diseases in Japan.

METHODS

We recruited 100 women from patients who underwent gynecological surgery followed by regimens standard for each disease. Subjects completed a questionnaire relating to life interferences, the Hospital Anxiety and Depression Scale (HADS) and the EuroQol 5 Dimension (EQ-5D) questionnaire. We compared differences in PROs between patients with benign tumors (n = 30) and malignant tumors (n = 70), and subsequently examined correlations between PROs after surgery and related variables.

RESULTS

Although the EQ-5D score was significantly higher in patients with benign tumors compared to those with malignant tumors, this association disappeared after controlling for confounders such as adjuvant therapies. Multiple regression analysis revealed that the number of months after surgery was positively correlated with the EQ-5D score, while the number of chemotherapy series was positively correlated with the number of life interferences. Moreover, the total number of drugs used in chemotherapy was positively correlated with the HADS-depression score and negatively correlated with the EQ-5D score.

CONCLUSIONS

The QOLs among gynecological cancer survivors may be associated with the chemotherapy and the term after surgery.

Efficacy and safety of acupuncture in postoperative ileus after gynecological surgery: A protocol for system review and meta-analysis of randomized controlled trials

BACKGROUND

Acupuncture is widely used in treatment of postoperative ileus (POI), but the safety and efficacy of acupuncture in POI after gynecological surgery still lack of evidence-based basis.

METHODS

PubMed, CINAHL, EMBASE, Web of science, Google Scholar, Wangfang database, Chinese Biomedical Literature Database (SinoMed), Chinese Science and Technology Periodical Database, and China National Knowledge Infrastructure database will be searched until December 31, 2020. Two independent investigators will screen the relevant randomized controlled trials from Data one by one by using prespecified criteria. The relevant data from included studies will be extracted and analyzed by using RevMan V.5.3 software. Quality of the included studies will be estimated by using the Cochrane Collaboration risk of bias tool, and publication bias will be assessed by using Egger test and Begg test. In addition, quality of evidence will be evaluated by using Grading of Recommendations Assessment, Development, and Evaluation.

RESULTS

We will analyze the effect of acupuncture on time to first flatus and time to bowel sound recovery as the primary outcomes of this review. Meanwhile, frequency of bowel sounds, time to defecation, time of hospital stay, biochemical indicators related to gastrointestinal motility, inflammation factors, responder rate, and adverse events for patients receiving gynecological surgery.

CONCLUSION

Our findings will benefit researchers and provide reference for the treatment and prevention of POI for the patients undergoing gynecological surgery.

Does prophylactic ureteral catheter placement offer any advantage for laparoscopic gynecological surgery? A urologist' perspective from a systematic review and meta-analysis

Our aim is to assess the efficacy of prophylactic ureteral catheter placement on patients undergoing laparoscopic gynecological surgery. We searched the electronic database including PubMed, Cochrane Library, Embase, Web of Science, WANFANG and CNKI in January 2020 to identify possible studies without languages limitations. A manual search was also conducted. The trials that compared catheterized group (CG) to non-catheterized group (NCG) were included. This meta-analysis was accomplished by RevMan5 (version 5.3). Initial search yield 997 studies and 5 randomized control trials were included in the final meta-analysis. Pooling data of five studies showed that patients in the CG had a lower risk of ureteral injury than those in NCG (RR: 0.44, 95% CI: 0.20–0.97, P=0.04) without significant between-study heterogeneity (P=0.23, I²=29%). The pooled data analysis showed a statistically significant difference in favor of prophylactic ureter catheter placement (MD: −40.51, 95% CI: −58.65 to −22.36, P<0.0001). Random-effects model meta-analysis found that patients in the CG experienced higher EBL compared to NCG (SMD: −5.78, 95% CI: −10.51 to −1.04, P=0.02). There was no statistically significant difference between CG group and NCG group (P=0.23) with regard to LOS. Current evidence indicates that prophylactic ureteral catheter placement has the advantages of reducing ureteral injury, shortening the operative time, and reducing the amount of bleeding. It might serve as a routine preoperative preparation choice for laparoscopic gynecological surgery, especially with pelvic adhesion. Further large volume, multicenter well-designed trials are warranted before making the final clinical guidelines.

Renal Calyceal Rupture following Ureteral Injury after Total Laparoscopic Hysterectomy

Ureteral injury (UI) complicates 0.1%-2.5% of total laparoscopic hysterectomies (TLHs). Renal calyceal rupture (RCR) is predominantly seen in patients with ureteral stones causing ureteral obstruction. Iatrogenic (surgical and nonsurgical) causes are responsible for only 3.5% of RCR. A 45-year-old gravida 4, para 2 female with a body mass index of 20 and no previous abdominal surgeries underwent a TLH due to hypermenorrhea and secondary anemia in the presence of a myomatous uterus. Intraoperatively, pelvic endometriosis and an isthmic myoma, 4 cm in diameter, were documented. On the 2^nd postoperative day, the patient reported right-sided loin pain. The computed tomography scan revealed a right-sided RCR with urine extravasation and a retroperitoneal and intra-abdominal urinoma. The patient was treated with a transitory nephrostomy for 6 months, and subsequently finally with ureteroneocystostomy (psoas hitch). This case extends the spectrum of iatrogenic RCR causes as well as UI manifestations after TLH.

A study of pregnancy after endometrial ablation using linked population data

INTRODUCTION

Endometrial ablation encapsulates a range of procedures undertaken to destroy the endometrial lining of the uterus as a treatment for heavy menstrual bleeding in women who no longer wish to bear children. Pregnancy following ablation, while unlikely, can occur and may carry higher rates of complications. The aim of this study was to identify factors associated with post-endometrial ablation pregnancy and to describe pregnancy and birth outcomes for post-endometrial ablation pregnancies.

MATERIAL AND METHODS

This population-based data linkage study included all female residents of New South Wales, Australia, aged 15-50 years with a hospital admission between July 2001 to June 2014 who birthed between July 2001 and June 2015. Cox proportional hazard regression was used to estimate associations between women's characteristics and post-endometrial ablation pregnancy of at least 20 weeks' gestation. Descriptive statistics were used to characterize pregnancy and birth outcomes.

RESULTS

Of 18 559 women with an endometrial ablation, 575 (3.1%) had a post-ablation pregnancy of at least 20 weeks' gestation. Nulliparity (adjusted hazard ratio [aHR] 12.2, 95% confidence interval [CI] 9.1-16.2), older age (35-39 years: aHR 0.39, 95% CI 0.29-0.51; 40-44 years: aHR 0.06, 95% CI 0.04-0.11), marital status (single: aHR 0.67, 95% CI 0.55-0.83; widowed/divorced/separated: aHR 0.58, 95% CI 0.36-0.94) and a diagnosis of heavy menstrual bleeding (aHR 0.09, 95% CI 0.07-0.13) were associated with post-ablation pregnancy. There were high rates of cesarean delivery (43%), preterm birth (13%), twin or higher order pregnancies (9%) and stillbirth (13.3/1000 births) among these post-ablation pregnancies.

CONCLUSIONS

Nulliparity at the time of endometrial ablation is associated with increased risk of post-ablation pregnancy, highlighting the importance of careful discussion and consideration of treatment options for heavy menstrual bleeding.

The impact of recent power morcellator risk information on inpatient surgery and patient outcomes

Aim: We examine the impact of the new risk information about a surgical device on surgery and patient outcomes for hysterectomy in the inpatient setting. Methods: We utilize a difference-in-differences approach to assess the impact of new risk information on patient outcomes in the inpatient setting between 2009 and 2014. The inpatient data come from a nationally representative sample of hospitalizations in the USA. We use the likelihood of laparoscopic surgery, measures of resource use and surgical complications as outcome variables. Results: We estimate a three-percentage point decrease in the likelihood of receiving laparoscopic hysterectomy, a one-percentage point increase in the likelihood of experiencing a surgical complication and no impact on resource use, relative to pre-existing means. Conclusion: Our findings show that there was movement away from laparoscopic surgery in the months following the dissemination of new risk information. These changes had limited effect on patient outcomes.

Factors for cecal intubation time during colonoscopy in women: Impact of surgical history

BACKGROUND/AIM

Cecal intubation during colonoscopy is prone to be prolonged in women, which may be related to frequent exposure to pelvic/abdominal surgery. We evaluated the association between Cecal Intubation Time (CIT) and prior episodes of pelvic/abdominal surgery in women.

PATIENTS AND METHODS

A cross-sectional study was conducted on screening participants who underwent colonoscopy. Multivariate regression with parameter estimates (β) was performed to determine the factors affecting CIT, including age, body mass index (BMI), bowel preparation, sedation, diverticulosis, experience of colonoscopists, and a surgical history. Also, subgroup analyses according to type of surgery were performed.

RESULTS

A total of 835 women were enrolled. The mean CIT was 5.82 ± 3.40 min. 323 females (38.7%) had episodes of surgery. The CIT was prolonged in cases performed by non-experienced trainees (β = 3.61, P< 0.001) and with a history of gynecological surgery (β = 0.97, P = 0.001). In the subgroup of non-experienced trainees, lower BMI, poor preparation, and a history of cesarean section significantly prolonged the CIT. Also, the risk for difficult colonoscopy (CIT ≥ 15 min) was increased with a history of cesarean section (odds ratio = 4.43, P= 0.024).

CONCLUSION

A prior episode of gynecological surgery prolonged CIT. Also, cesarean section history was associated with difficult colonoscopy in the examination by non-experienced trainees.

Laparoscopic vs percutaneous hysterectomy in obese patients: a prospective evaluation

BACKGROUND

Treatment of obese female patients represents a real challenge. Indeed, obesity among women has reached epidemic levels not only elevating the cardiovascular and endocrinological risks, but also increasing the incidence of various gynecological pathologies (e.g. endometrial cancer and hyperplasia, uterine fibroids, genital prolapse) which commonly require hysterectomy as a surgical solution. In the last decade, minimally invasive surgery has emerged as an approach reducing the invasiveness of the standard laparoscopic surgical procedures while maintaining efficacy and feasibility. As such, in this study we aimed to evaluate the feasibility of percutaneous hysterectomy (PSS-H) approach in obese patients by reporting the first prospective comparison between the PSS-H to laparoscopic hysterectomy (LPS-H).

METHODS

In this multicentric comparative prospective study, 45 patients affected by benign and malignant gynecological conditions were considered eligible for minimally invasive surgery (MIS). Fifteen patients received PSS-H and 30 LPS-H. All patients enrolled received a total hysterectomy ± bilateral salpingo-oophorectomy, with or without lymph nodal staging.

RESULTS

No statistically significant differences were noted in operative time and estimated blood loss between the two groups. Four patients in PSS-H group and 3 in LPS-H group received lymph node staging. A multifunctional energy device was used in all PSS-H and 73.3% of LPS-H procedures (p=0.038). There were no conversions to laparotomy in either group and similarly there were no conversions to conventional laparoscopy in the PSS-H group. In the LPS-H group, there was one (3.3%) case of major bleeding( ≥ 500 mls). We recorded one vaginal cuff bleeding in PSS-H, whereas for LPS-H we reported 4 (13.3%) 30-days complications (p=0.651). No differences in visual analogue scale (VAS) score were recorded. A significant disparity was noted in cosmetic outcome at discharge (p=0.001), but not after 30 days.

CONCLUSION

We demonstrated for the first time, in a prospective comparison between PSS and LPS approaches, that PSS-H may represent a valid alternative to performing total hysterectomy in obese patients.

Laparoscopic uterine ventrosuspension procedure by using anterior mesh incorporated with bilateral round ligamentopexy: Kahyaoglu technique

A number of vaginal and abdominal surgical techniques have been described for the treatment of apical uterine prolapse. A 38-year-old parous woman has been operated laparoscopically due to grade 3 apical uterine prolapse. A new surgical technique for the treatment of apical uterine prolapse performed by incorporation of the lateral arms of anteriorly anchored uterine polypropylene mesh to bilateral round ligaments has been developed. Due to the young age of the patient and lack of any other uterine pathology, a laparoscopic uterine ventrosuspension procedure combined with bilateral round ligamentopexy has been performed as a low risk uterine prolapse surgery.

Adhesions and Anti-Adhesion Systems Highlights

The peritoneal and intrauterine cavities are lined by fragile membranes with a high-wound healing capacity, e.g. repairing the endometrium in its cyclical "injury and scar-free repair process" during menstruation. However, peritoneal and intrauterine fibrosis and adhesions can develop after surgical trauma through activation of molecular, immune and genetic mechanisms. During procedures with a high-risk of adhesions, the use of new peritoneal and intrauterine conditions in combination with anti-adhesion substances are promising measures to preserve peritoneal and endometrial function and avoid the most common complication of gynecological surgery. Highlights of adhesions and anti-adhesion prevention techniques in laparoscopic, laparotomic and hysteroscopic surgeries are discussed in this paper. Unfortunately, evidence is lacking to prove the superiority of one technique over its counterparts in terms of postoperative adhesions, such as instrumentation, type of energy, distending media, and intracavitary pressure. Additionally, there is limited evidence about the efficacy and outcomes of techniques and adjuvant measures used during adhesiolysis. The definition of a universal intrauterine adhesions classification scheme as well as a prognostic scoring system to identify women at high risk of postoperative adhesions are necessary for advising those who could benefit the most of the use of antiadhesion barriers.

Effect of Intravenous Oxycodone Versus Sufentanil on the Incidence of Postoperative Nausea and Vomiting in Patients Undergoing Gynecological Laparoscopic Surgery

More than 30% of patients who undergo surgery will experience postoperative nausea and vomiting (PONV) if no prophylactic treatments are used. Although numerous studies have been performed to investigate the factors related to PONV, the effect of perioperative intravenous oxycodone on the incidence of PONV has not been well investigated. In this study, gynecological patients (grade I-II, aged 18-65 years, scheduled to undergo elective gynecological laparoscopic surgery under general anesthesia) were randomized to the oxycodone group or the sufentanil group. In the oxycodone group, patients received intravenous oxycodone for the induction and maintenance of anesthesia, as well as postoperative analgesia, while sufentanil was used in the sufentanil group. The primary outcome variable was the incidence of PONV. As secondary outcomes, time to first PONV, the rating of the most severe PONV, postoperative pain scores at different time points, hemodynamics, and side effects were evaluated. We found that, compared with sufentanil, oxycodone decreased the incidence of PONV by 13.5% (P = .041). The time to first vomiting was longer in the oxycodone group than in the sufentanil group. Postoperative pain scores at different time points and hemodynamics were comparable between the oxycodone and sufentanil groups. We concluded that the incidence of PONV in gynecological patients who underwent laparoscopic surgery was lower when using intravenous oxycodone for anesthesia induction, anesthesia maintenance, and postoperative analgesia than when using intravenous sufentanil. However, oxycodone and sufentanil provided the same stable hemodynamics during surgery and satisfactory postoperative analgesia.

Mucinous Cystadenoma Causing Abdominal Distension: A Case Report

Mucinous cystadenomas are a common benign neoplasm of the ovaries that can grow much larger than other adnexal masses. We report a case of a 28-year-old female who presented with one month of increasing abdominal distension and upper abdominal pain; she was found to have a 30-centimeter (cm) adnexal mass. Pathology showed a benign mucinous cystadenoma with no evidence of malignancy. The authors discuss the initial evaluation and management of adnexal masses in general, as the variety of etiologies and severity can make this a difficult task. The characteristics of different adnexal masses and the indications for gynecologic consultation and surgery are also discussed.

Assessment of laparoscopic training for gynecological malignancies using Thiel-embalmed human cadavers

The introduction of laparoscopic surgery has also been beneficial for patients with gynecological malignancies. In this respect, surgeons should receive related training in the context of human resource development. Hands-on training was introduced using Thiel-embalmed human cadavers (THCs) in 2014. To determine the usefulness of THCs, they were evaluated in terms of tissue color, consistency and operative tactility, among others, compared with in vivo laparoscopic training for gynecological malignancies. Hands-on training sessions using THCs were held for a total of 11 times at Ehime University Graduate School of Medicine between March 2014 and October 2017. Training on THCs included advanced laparoscopic procedures for radical hysterectomy type III. At the end of each training session, data were collected using a standardized, anonymous questionnaire termed the Likert scale. THCs ensured flexibility and plasticity of tissues and organs; therefore, the working space was similar to that in the living body under pneumoperitoneum. After analyzing the quality and consistency of tissue and organ color compared with in vivo conditions, most of the participants agreed or strongly agreed regarding the uterus, adnexa and ureter, but not regarding the large blood vessels. The highest scores were observed in the authenticity of the anatomical condition of each organ. Most participants strongly agreed that training using THCs would help improve their laparoscopic skills with a high level of satisfaction. Furthermore, most participants reported that they would recommend this training to other obstetrician-gynecologists. Laparoscopic training for gynecological malignancies using THCs was comparable to the in vivo conditions in terms of surgical view and operative tactility. Therefore, THCs may be an excellent training tool for improving laparoscopic surgical skills for gynecological malignancies.

Use of a gelatin-thrombin hemostatic matrix in obstetrics and gynecological surgery

Gelatin-thrombin matrix (GTM) is a hemostatic sealant consisting of bovine-derived gelatin matrix and human-derived thrombin, combining both mechanical and active mechanisms to achieve hemostasis. It was approved by the Food and Drug Administration in 1999. GTM has been used by several surgical specialties; however, it is a possibly an under-used tool in obstetrics and gynecology. A limited number of studies have been performed on its use during laparoscopic endometrioma excision and myomectomy. It may prove useful in endometrioma excision in reproductive aged women because it is likely to harm ovarian reserve less than electrocautery; however, this conclusion needs to be validated. The only study on GTM use in myomectomy included 50 women randomized into GTM and control groups, and showed decreased blood loss and shorter hospital stays in the GTM group. In gynecologic oncology, it was successfully used to reduce lymphocele cases in a cohort study. GTM has been used successfully in obstetrics in a handful of cases of uncontrolled bleeding from caesarean scar, placental site, ectopic pregnancy, rectovaginal hematoma, and venous plexus over the vaginal vault after emergency postpartum hysterectomy. Risk of viral transmission is a major concern about GTM, yet there are no reports on disease transmission with GTM use to date. Rare but serious adverse effects and complications have been reported such as fatal or near-fatal thromboembolism and small bowel obstruction. Although GTM is mostly a safe product, it is still not free of complications and risks. In conclusion, although routine use of GTM cannot be recommended due to concerns about its safety, cost, and availability, it may prove useful when conventional hemostatic methods such as suturing and electrocauterization fail or are not appropriate.
