Evaluating Surgical Complexity of Endoscopic Hysterectomy: An Inter-rater and Intra-rater Agreement Study of Novel Scoring Tool.

STUDY OBJECTIVE: Evaluate inter-rater and intrarater reliability of a novel scoring tool for surgical complexity assessment of endoscopic hysterectomy. DESIGN: Validation study. SETTING: Academic medical center. PARTICIPANTS: Total of 11 academic obstetrician-gynecologists with varying years of postresidency training, clinical practice, and surgical volumes. INTERVENTIONS: Application of a novel scoring tool to evaluate surgical complexity of 150 sets of images taken in a standardized fashion before surgical intervention (global pelvis, anterior cul-de-sac, posterior cul-de-sac, right adnexa, left adnexa). Using only these images, raters were asked to assess uterine size, number, and location of myomas, adnexal and uterine mobility, need for ureterolysis, and presence of endometriosis or adhesions in relevant locations. Surgical complexity was staged on a scale of 1 to 4 (low to high complexity). MEASUREMENTS AND MAIN RESULTS: Number of postresidency years in practice for participating surgeons ranged from 2 to 15, with an average of 8 years. A total of 8 obstetrician-gynecologists (72.7%) had completed a fellowship in minimally invasive gynecologic surgery. Six (54.6%) reported an annual volume of >50 hysterectomies. Raters reported that 95.4% of the images were satisfactory for assessment. Of the 150 sets of images, most were found to be stage 1 to 2 complexity (stage 1: 23.8%, stage 2: 41.6%, stage 3: 32.8%, stage 4: 1.8%). The level of inter-rater agreement regarding stage 1 to 2 vs 3 to 4 complexity was moderate (κ = 0.49; 95% confidence interval [CI], 0.42-0.56). Moderate inter-rater agreement was also found between surgeon raters with an annual hysterectomy volume >50 (κ = 0.49; 95% CI, 0.40-0.57) as well as between surgeon raters with fellowship experience (κ = 0.50; 95% CI, 0.42-0.58). Intrarater agreement averaged 80.2% among all raters and also achieved moderate agreement (mean weighted κ = 0.53; range, 0.38-0.72). CONCLUSION: This novel scoring tool uses clinical assessment of preintervention anatomic images to stratify the surgical complexity of endoscopic hysterectomy. It has rich and comprehensive evaluation capabilities and achieved moderate inter-rater and intrarater agreement. The tool can be used in conjunction with or instead of traditional markers of surgical complexity such as uterine weight, estimated blood loss, and operative time.

Utilizing the Operating Room Black Box to Characterize Intraoperative Delays, Distractions, and Threats in the Gynecology Operating Room: A Pilot Study.

Introduction Operating Room Black Box (ORBB) technology can be used to capture information during surgery for analysis and potential identification of root causes that jeopardize safety and efficiency. In this study, our objective was to identify and characterize procedural steps, intraoperative distractions, errors, and threats, as well as the non-technical skills of the team during a common minimally invasive gynecologic procedure. Methodology This was a cross-sectional pilot study of 25 patients undergoing total laparoscopic hysterectomy between May 2019 and February 2020 at a Canadian tertiary care academic hospital. Video, audio, and patient physiologic data from all procedures were obtained through a multichannel synchronized recording device (ORBB). Trained analysts reviewed and coded the recordings. Results The median total case time was 165 minutes (interquartile range [IQR]: 160-178 minutes) with the shortest step being cystoscopy and the longest being vaginal cuff closure. Time pressure and device absence or malfunction occurred in 48% of the cases, and a median of 262 (IQR: 228-304) auditory distractions were noted per case. There was a median of 3 (IQR: 2-4) safety threats identified per case and at least one error was identified in 11/25 cases (44%). Only two adverse events were noted among all 25 cases. Observed non-technical skills were mainly positive, and observations were the highest for situational awareness and leadership among the surgical team and communication and teamwork among the nursing/scrub technician and anesthesia teams. Conclusions This study is a novel application of the ORBB in the gynecology operating room to capture information regarding procedure times, intraoperative distractions, errors, and non-technical skills of the team. Frequent intraoperative cognitive and auditory distractions were noted. Although adverse events were rare, safety threats were identified. Ongoing and future research from our group will aim to identify key areas for organizational, technological, and team improvement to minimize inefficiencies and optimize patient safety in the operating room.

Robotic-Assisted Laparoscopic Hysterectomy for Endometrial Hyperplasia or Grade 1 Endometrial Adenocarcinoma: A 10-year, Single-Centre Experience.

OBJECTIVE: To describe the outcomes of patients undergoing robotic-assisted laparoscopic hysterectomy for grade-1 endometroid endometrial cancer or endometrial hyperplasia at our centre. METHODS: Retrospective chart review was completed for 160 patients who underwent robotic-assisted laparoscopic hysterectomy by 5 general gynaecologists in a tertiary care setting between September 2008 and September 2018. Outcomes collected included operative time, estimated blood loss, length of stay, perioperative complications, readmissions, and recurrences. Subgroup analysis was completed after stratifying by body mass index (BMI; 3 groups: A, <40 kg/m2; B, 40-50 kg/m2; and C, >50 kg/m2). Subgroups were compared with ANOVA or Fisher exact test. RESULTS: The intraoperative complication rate was 3%. The rate of conversion to laparotomy was 2%, and the rate of bowel injury, 1%. The postoperative complication rate was 8%. The rate of major postoperative complications was 4%, and 3% of patients required readmission postoperatively. The mean BMI was 43 (range 21-71) kg/m2. There were no differences in perioperative complication, readmission, or recurrence rates between subgroups. Groups B and C were more likely to have had an ASA of 3-4, suggesting a higher burden of comorbidity. Operating room time, procedure time, and estimated blood loss were higher in group C. CONCLUSION: Despite this cohort's mean BMI falling within the category of class III obesity, complication and conversion rates were similar to those reported in the literature and did not increase with BMI, despite an increased comorbidity burden. These results suggest that robotic surgery is a safe and effective method for providing minimally invasive surgery to a technically challenging population.

Impact of a Blood Conservation Bundle Checklist on Perioperative Transfusion Rates during Myomectomy.

STUDY OBJECTIVE: The primary objective was to introduce an intraoperative blood conservation bundle (BCB) checklist into clinical practice and assess its impact on perioperative blood transfusion rates during myomectomy. DESIGN: Prospective cohort study with retrospective control group. SETTING: A Canadian tertiary-care teaching hospital. PATIENTS: One hundred and eighty-six women who underwent myomectomy. INTERVENTIONS: The BCB is a physical checklist attached to the patient chart and consists of evidence-based medical and surgical interventions to reduce intraoperative blood loss. It was introduced in October 2018, and data were collected prospectively during a 12-month period for all open, robotic, and laparoscopic myomectomies at our institution. The primary outcome was the perioperative transfusion rate, and the secondary outcomes included estimated intraoperative blood loss, perioperative complications, readmissions, and BCB usage rates. Data were compared with those of a historic control group for a 24-month period before the BCB introduction. MEASUREMENTS AND MAIN RESULTS: In the pre-BCB period, 134 myomectomies (90 open, 31 robotic, and 13 laparoscopic) were performed, and during our study period, 52 myomectomies (33 open, 10 robotic, and 9 laparoscopic) were performed. There was a decrease in transfusion rate from 15.7% (21/134) to 7.7% (4/52) after introduction of the BCB; however, this was not significant (p = .152). The mean estimated blood loss was lower postintervention (491 mL ± 440 mL vs 350 mL ± 255 mL; p <.05) as was the mean delta hemoglobin (-28 g/L ± 13.0 g/L vs -23 g/L ± 11.4g/L; p <.05]. The checklist was used in 92.3% of cases (48/52). There were no differences in intraoperative or postoperative complications or readmission rates. CONCLUSION: Best practice care bundles can improve knowledge translation of guidelines into care delivery. The introduction of the BCB was successful in reducing intraoperative blood loss during myomectomy at our institution. The BCB is a simple, effective tool that can be easily adopted by gynecologic surgeons to guide intraoperative decision-making during myomectomy.

Enhanced Recovery and Surgical Optimization Protocol for Minimally Invasive Gynecologic Surgery: An AAGL White Paper.

This is the first Enhanced Recovery After Surgery (ERAS) guideline dedicated to standardizing and optimizing perioperative care for women undergoing minimally invasive gynecologic surgery. The guideline was rigorously formulated by an American Association of Gynecologic Laparoscopists Task Force of US and Canadian gynecologic surgeons with special interest and experience in adapting ERAS practices for patients requiring minimally invasive gynecologic surgery. It builds on the 2016 ERAS Society recommendations for perioperative care in gynecologic/oncologic surgery by serving as a more comprehensive reference for minimally invasive endoscopic and vaginal surgery for both benign and malignant gynecologic conditions. For example, the section on preoperative optimization provides more specific recommendations derived from the ambulatory surgery and anesthesia literature for the management of anemia, hyperglycemia, and obstructive sleep apnea. Recommendations pertaining to multimodal analgesia account for the recent Food and Drug Administration warnings about respiratory depression from gabapentinoids. The guideline focuses on workflows important to high-value care in minimally invasive surgery, such as same-day discharge, and tackles controversial issues in minimally invasive surgery, such as thromboprophylaxis. In these ways, the guideline supports the American Association of Gynecologic Laparoscopists and our collective mission to elevate the quality and safety of healthcare for women through excellence in clinical practice.

Measures to Reduce Perioperative and Intraoperative Blood Loss at Myomectomy: A Survey of Obstetrician-Gynaecologists.

OBJECTIVE: This study sought to determine current techniques used by Canadian obstetrician-gynaecologists (OB/GYNs) to medically optimize patients undergoing myomectomy during the perioperative and intraoperative periods and to identify gaps in knowledge or barriers to access of blood conservation methods. METHODS: From September to December 2016, a self-administered electronic questionnaire was distributed to 120 Canadian OB/GYNs who perform myomectomies and who practise in either academic, community, or community academic-affiliated hospitals. RESULTS: A total of 68 of 120 (57%) completed responses were analyzed. Most respondents were general OB/GYNs (72.1%; n = 49) who worked in the community (70.6%; n = 48) and had practised >10 years (67.7%; n = 46); 79.4% (n = 54) delayed surgery to correct anemia. The most common preoperative medical agents used included tranexamic acid (94.1%), ulipristal acetate (92.6%), gonadotropin-releasing hormone agonist (79.4%), and combined hormonal contraception (58.8%). The majority had access to hematology (83.8%; n = 57) and intravenous iron (82.4%; n = 56). However, respondents had variable knowledge of oral and intravenous iron dosing and administration. The most common intraoperative agents used included vasopressin (94.1%; n = 64 [subserosal, 59.4% vs. intramyometrial, 40.6%]), vasopressin with epinephrine (26.6%; n = 17 [subserosal, 58.8% vs. intramyometrial, 41.2%]), intravenous tranexamic acid (73.5%; n = 50), mechanical tourniquet (66.2%; n = 45), misoprostol (33.8%; n = 23), uterine artery ligation (22.1%; n = 15), topical sealant (17.6%; n = 12), and intraoperative blood salvage (11.8%; n = 8). CONCLUSION: Most OB/GYNs delay surgery to correct anemia, but they are uncertain of personal and institutional transfusion rates, iron dosing and administration, and optimal multimodal approaches to minimize intraoperative blood loss during myomectomy. Education and creation of a clinical pathway to address blood conservation may decrease perioperative morbidity for patients undergoing myomectomy.

Implementation of a Same-Day Discharge Protocol Following Total Laparoscopic Hysterectomy.

OBJECTIVE: Previous studies have demonstrated that outpatient total laparoscopic hysterectomy (TLH) is both safe and feasible. Our objective was to decrease length of stay for patients undergoing TLH by implementing a same-day discharge protocol at two Canadian teaching hospitals. METHODS: We conducted a prospective cohort study assessing length of stay (primary outcome), perioperative complications, and readmission rates over a 12-month period following implementation of a same-day discharge protocol for TLH. These data were compared with pre-intervention baseline data collected retrospectively over a 12-month period immediately before protocol introduction. Our protocol consisted of patient education, instructions for perioperative care, and close follow-up. RESULTS: In the year prior to our protocol, 256 TLHs were performed. Forty-seven patients (18.3%) were discharged the same day, 191 patients (74.5%) were discharged on the first postoperative day, and 18 patients (7%) were admitted for 2 or more days. In the year following implementation, 215 patients underwent TLH of which 129 were enrolled in our study. The overall outpatient hysterectomy rate during that time period was 62% (134/215 patients). Among study participants, 102 patients (79.1%) were discharged the same day, 22 patients (17.0%) were discharged on the first postoperative day, and 5 patients (3.9%) were admitted for 2 or more days. There were no significant differences in perioperative complications or readmission rates and patient satisfaction scores were high. CONCLUSION: Implementation of a same-day discharge protocol successfully increased the rate of outpatient TLH without impacting patient safety. This protocol was acceptable to both surgeons and patients and can be easily adapted for use at other centres.
