[Reducing the Time Before the Console in Robotic-Assisted Laparoscopic Hysterectomy].

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

Assessment of the self-confidence of obstetrics & gynecology fellows to perform a postpartum hemostasis hysterectomy.

INTRODUCTION: Hemostasis Hysterectomy (HH) is a last resort surgical procedure performed in situations of uncontrolled post-partum hemorrhage in maternity wards. The chances of being confronted with this situation are scarce during residency, and the situation is not well suited for teaching. Nevertheless, every obstetrician-gynecologist can be confronted with this stressful situation, and should therefore possess the surgical competence required, regardless of his routine practice. The aim of the present study is to evaluate clinical exposure and self-awareness concerning HH amongst obstetrics and gynecology residents and fellows. MATERIEL AND METHODS: We performed a survey amongst French obstetrics and gynecology fellows. An anonymous survey was sent by email between December 1, 2020 to July 1, 2021. RESULTS: Half of the interrogated fellows had practiced (as operator) an HH during residency with a senior and only 22,6% in post-residency. During the last year of residency 70% of them had performed less than 10 scheduled hysterectomies as primary operator. The laparoscopic approach was the most frequently practiced. Very few hysterectomies were performed as primary operator. Fellows with a surgical or mixed activity (both gynecological surgery and obstetrical activity in current practice) felt significantly more capable of performing HH compared to those with exclusive obstetrical or reproductive medicine activity; respectively 60% vs 36%, p = 0.008; Odds Ratio: 2.629 (95% CI 1.2214; 5.8094). CONCLUSION: The number of scheduled hysterectomies or HH performed as primary operator is very low during residency or fellowship. It remains largely inferior to the number deemed necessary in previous publications about the learning curve for scheduled hysterectomy, which varies from 18 to 80 interventions. Nowadays, the increasing number of residents, added to the decrease of hemostasis hysterectomies through better management of post-partum hemorrhage, pushes towards the development of specific training, such as "damage control simulation".

Total laparoscopic hysterectomy four-handed ergonomic technique: description of an original surgical procedure for the reduction of learning curve.

The aim of this study was to propose the four-handed technique for total laparoscopic hysterectomy (TLH), with or without adnexectomy. From our point of view this is a more ergonomic, efficient, and effective technique that can contribute to the training of specialists in obstetrics/gynecology. In fact, teacher and learner have both an active role on the surgical field using two laparoscopic instruments each. They are alternately, mutually, and symmetrically first operator and assistant, reducing number of attempts needed for laparoscopic hysterectomy learning curve. The detailed description of all the surgical steps of TLH, "four-handed technique" (FHT), with or without adnexectomy, make sure that it can be effectively reproduced step by step safely, by transposing "FHT" surgical steps of laparotomic approach. This may allow easy access to anatomical spaces inserting trocars in different ways. By clearly knowing the steps of TLH, "FHT" it is possible to favor minimally invasive routes so that patients benefit from its multiple proven benefits. Operating this way, operative time, blood loss, use of analgesics and hospitalization can be significantly reduced. In conclusion benefits of TLH have already been widely demonstrated in literature. It is a real opportunity that young specialists become confident with this innovative "FHT," a procedure that allows them to be surgeon first assistant, and in which they can learn faster real intraoperative stereotaxis and surgical steps sequence, familiarizing with the anatomy of retroperitoneal space.

A mixed-method evaluation of cadaver surgery training for gynecologic oncology.

AIM: Traditional surgical training techniques with using patients, and new advances with live animals, artificial models, and simulation methods have several shortcomings. There are a few reports on the usefulness of cadaver surgery training (CST) in gynecology. Herein, we used a mixed-method evaluation to qualitatively and quantitatively explore the educational efficacy of CST by conducting CST programs at the Sapporo Medical University, Japan. METHODS: In 2020, we conducted two CST programs with 45 participants-13 residents, 8 specialists recognized by Japan Society of Obstetrics and Gynecology, 23 certified endoscopists recognized by Japan Society of Gynecology and Obstetrics Endoscopy and Minimally Invasive Therapy, 15 specialists recognized by Japan Society of Gynecologic Oncology, and 14 certified endoscopists cum oncology. Three participants observed the procedure virtually and 42 were physically present. Laparoscopic radical hysterectomy and pelvic exenteration were performed on five Thiel-embalmed cadavers. Participants were asked to complete pre- and post-training surveys that included qualitative questions, concerning the purpose and cost of CST, and quantitative questions, testing anatomical knowledge. RESULTS: We observed that the rate of score improvement to the quantitative questions increased from 58.6% pre-CST to 75.6% post-CST. Furthermore, oncology specialists and those who performed more surgeries and faced more complications during surgeries recorded high percentage of correct answers. Multiple regression analysis statistically confirmed these results. CONCLUSIONS: This study confirmed the educational efficacy of CST.

Simulation-based training using a novel Surabaya hysterectomy mannequin following video demonstration to improve abdominal hysterectomy skills of obstetrics and gynecology residents during the COVID-19 pandemic in Indonesia: a pre- and post-intervention study.

PURPOSE: During the coronavirus disease 2019 (COVID-19) pandemic, the number of abdominal hysterectomy procedures decreased in Indonesia. The existing commercial abdominal hysterectomy simulation model is expensive and difficult to reuse. This study compared residents' abdominal hysterectomy skills after simulation-based training using the Surabaya hysterectomy mannequin following a video demonstration. METHODS: We randomized 3rd- and 4th-year obstetrics and gynecology residents to a video-based group (group 1), a simulation-based group (group 2), and a combination group (group 3). Abdominal hysterectomy skills were compared between before and after the educational intervention. The pre- and post-tests were scored by blinded experts using the validated Objective Structured Assessment of Technical Skills (OSATS) and Global Rating Scale (GRS). RESULTS: A total of 33 residents were included in the pre- and post-tests. The OSATS and GRS mean differences after the intervention were higher in group 3 than in groups 1 and 2 (OSATS: 4.64 [95% CI, 2.90-6.37] vs. 2.55 [95% CI, 2.19-2.90] vs. 3.82 [95% CI, 2.41-5.22], P=0.047; GRS: 10.00 [95% CI, 7.01-12.99] vs. 5.18 [95% CI, 3.99-6.38] vs. 7.18 [95% CI, 6.11-8.26], P=0.006). The 3rd-year residents in group 3 had greater mean differences in OSATS and GRS scores than the 4th-year residents (OSATS: 5.67 [95% CI, 2.88-8.46]; GRS: 12.83 [95% CI, 8.61-17.05] vs. OSATS: 3.40 [95% CI, 0.83-5.97]; GRS: 5.67 [95% CI, 2.80-8.54]). CONCLUSION: Simulation-based training using the Surabaya hysterectomy mannequin following video demonstration can be a bridge to learning about abdominal hysterectomy for residents who had less surgical experience during the COVID-19 pandemic.

Standardized Surgical Video Curriculum for Teaching Residents Principles of Abdominal Hysterectomy.

OBJECTIVES: To evaluate whether an institutionally created video-based educational module will improve obstetrics and gynecology residents' understanding of surgical anatomy and principles for performing abdominal hysterectomy. Secondary aims included evaluating the trainees' confidence levels and perceptions before and after the educational experience and ultimately implementing the module into the program curriculum, if successful. METHODS: In this prospective study, postgraduate obstetrics and gynecology resident physicians (n = 27) at the McGaw Medical Center of Northwestern University were assigned to watch an institutionally created video-based educational module on abdominal hysterectomy before the start of their gynecologic oncology rotation. A knowledge assessment and a postmodule survey were given to participants immediately following the module and repeated at the end of the 4-week rotation. RESULTS: Participants reported a median rating of 4 (n = 21, interquartile range 4-4) on a 5-point Likert scale when asked to rate the quality of the module. The module also was rated as equally effective both immediately after watching the module and after completing their gynecologic oncology rotation (median 4, interquartile range 3-4 at both times; p = 0.299, Wilcoxon signed rank test). Overall trends revealed that the video module had a greater impact on knowledge of surgical anatomy than on self-reported surgical skills and that postgraduate year 2 and postgraduate year 3 residents benefited more from the intervention. CONCLUSIONS: A video module can be a high-quality and effective educational tool for teaching the surgical principles, anatomy, and steps to perform abdominal hysterectomy to obstetrics and gynecology residents.

Training for next generation surgeons: a pilot study of robot-assisted hysterectomy managed by resident using dual console.

PURPOSE: To assess feasibility of a standardized robot-assisted hysterectomy managed by resident and supervised by senior surgeon using dual-console on a 21-step grid (max score = 42) assessing resident autonomy. METHODS: A total of seven patients managed between September 2019 and March 2020 by six residents in gynecology and obstetrics were included. Standardized robot-assisted hysterectomy for endometrial cancer or adenomyosis was performed. RESULTS: No conversion to laparotomy, no intra- or post-operative incidents were reported. Mean score on the evaluation scale was 29.8 out of 42 (SD = 7.3). Mean operative time was 104 min (SD = 23). Mean average suturing time was, respectively, 335 s (SD = 57 s) and 270 s (SD = 53 s) for the first and the fourth knot. There was a 65 s improvement between the first and the fourth intracorporeal knot (p = 0.043). The perceived workload evaluated with the NASA TLX score showed a low level of stress (Temporal demand = 1.6 /10), and a low level of frustration (Frustration level = 3.6/10). Experience gained during the surgery was felt to be important (Commitment = 8.6/10). CONCLUSION: Standardized robot-assisted hysterectomy managed by a resident supervised by a senior surgeon using the dual-console seems feasible. This tool could be useful to assess residents' surgical skills.

Resident and Program Director Confidence in Resident Surgical Preparedness in Obstetrics and Gynecologic Training Programs.

OBJECTIVE: To assess self-reported readiness of U.S. obstetrics and gynecology residents to perform surgical procedures compared with the perceptions of their program directors. METHODS: The 2019 Council on Resident Education in Obstetrics and Gynecology Survey assessed resident self-confidence and perceived readiness to independently perform common surgical procedures. Concurrently, obstetrics and gynecology residency program directors were surveyed about the readiness of their graduating residents to independently perform the same procedures. RESULTS: The overall response rate was 99.3% for residents (5,473/5,514 examinees attempted to complete the survey) and 83% for program directors (241/292 returned surveys). There were no significant differences in graduating residents and program directors' assessments of graduating residents' surgical confidence in performing cesarean delivery (99.6% [95% CI 98.9-99.9] vs 100% [95% CI 98.2-100.0]), vacuum delivery (96.5% [95% CI 95.2-97.4] vs 98.6% [95% CI 95.9-99.7]), abdominal hysterectomy (95.1% [95% CI 93.6-96.2] vs 96.7% [95% CI 93.3-98.7]) or operative hysteroscopy (99.5% [95% CI 98.9-99.9] vs 100% [95% CI 98.2-100.0]). Ninety percent, 86%, and 69% of graduating residents felt that they could independently perform an abdominal hysterectomy, laparoscopic hysterectomy, and vaginal hysterectomy, respectively, in the event of an emergency. Ninety-seven percent (95% CI 93.3-98.7) of program directors reported their residents could perform a laparoscopic hysterectomy by graduation, as did 93% of graduating resident respondents (95% CI 90.8-94.0). Ninety percent (95% CI 85.3-93.8) of program directors felt their residents could perform vaginal hysterectomies by graduation, compared with 79% (95% CI 76.9-81.8) of fourth-year residents. CONCLUSION: Graduating obstetrics and gynecology residents and their program directors are confident in their abilities to perform the majority of core surgical procedures by graduation. By the second year, more than 90% of residents and their program directors were confident in their ability to perform cesarean deliveries and operative hysteroscopy. Sixty-nine percent and 86% of graduating residents felt comfortable performing vaginal and laparoscopic hysterectomies, respectively.

Comparing Surgical Experience and Skill Using a High-Fidelity, Total Laparoscopic Hysterectomy Model.

OBJECTIVE: To evaluate differences in standardized scores and surgical confidence in the completion of a standardized total laparoscopic hysterectomy and bilateral salpingo-oophorectomy (TLH-BSO) among obstetrician-gynecologists (ob-gyns) with different levels of training, and to assess a TLH-BSO model for validity. METHODS: We conducted a prospective cohort study of 68 participants within four categories of ob-gyns: 1) graduating or recently graduated residents (n=18), 2) minimally invasive gynecologic surgery graduating or recently graduated fellows (n=16), 3) specialists in general obstetrics and gynecology (n=15), and 4) fellowship-trained minimally invasive gynecologic surgery subspecialists (n=19) who completed a TLH-BSO simulation. Participants completed presimulation questionnaires assessing laparoscopic confidence. Participants performed a video-recorded TLH-BSO and contained specimen removal on a standardized 250-g biological model in a simulated operating room and completed a postsimulation questionnaire. RESULTS: Randomized videos were scored by blinded experts using the validated OSATS (Objective Structured Assessment of Technical Skills). The surgery was divided into five standardized segments: 1) adnexa, 2) dissection and pedicles, 3) colpotomy, 4) cuff closure, and 5) tissue extraction. Minimally invasive gynecologic surgery subspecialists averaging 8.9 years in practice scored highest in all categories (overall median score 91%, P<.001), followed by fellows (64%, P<.001), specialists in obstetrics and gynecology averaging 19.7 years in practice (63%, P<.001), and residents (56%, P<.001). Residents, fellows and specialists in obstetrics and gynecology were comparable overall. Fellows scored higher on cuff closure (63% vs 50%, P<.03) and tissue extraction (77% vs 60%, P<.009) compared with specialists in obstetrics and gynecology. Minimally invasive gynecologic surgery subspecialists were fastest overall and on each individual component. Residents were slowest in almost all categories. CONCLUSION: When performing a TLH-BSO of a standardized 250-g uterus on a simulation model, fellowship-trained minimally invasive gynecologic surgery subspecialists achieved higher OSATS in all areas and completed all components faster. Similar performances were noted between residents, fellows, and specialists in obstetrics and gynecology in practice an average of 19.7 years. FUNDING SOURCE: Support from Applied Medical, Medtronic, CooperSurgical, and Karl Storz in the form of in-kind equipment was obtained through unrestricted educational grants.

YouTube as a Source of Information and Education on Hysterectomy.

BACKGROUND: Globally, YouTube is one of the most popular websites, and the content is not restricted to entertainment. The purpose of this study was to assess the quality of information in YouTube videos pertaining to hysterectomy. METHODS: We explored YouTube using the search terms "hysterectomy" and "remove uterus." The videos that appeared were sorted using the filter "sort by view count." Of the initial 100 videos, the top 50 videos for each search term were included for review, as determined by the "relevance" filter based on YouTube's algorithm. After excluding 34 videos for various reasons, 66 were included in the final analysis. Each video rated as "useful" was further analyzed for reliability and completeness of information; a set of pre-determined criteria were modified from a previous study and used to grade the quality of videos. RESULTS: The top 66 videos on hysterectomy had a total of 4,679,118 views. Based on authorship, the videos were categorized as follows: videos uploaded by patients, 37%; academic videos, 35%; videos uploaded by physicians, 13%; commercial videos, 4%; and videos uploaded by non-physicians, 2%. The type of content was also categorized: 50% of the videos recorded personal experiences, 23% recorded surgical techniques, 21% involved explanations of the surgery, and 4% were commercial videos. The majority of the videos made by patients were negatively biased toward hysterectomy surgery (71.72%), while the majority of those made by academics or physicians were surgical educational videos for doctors, not patients. CONCLUSION: YouTube is currently not an appropriate source for patients to gain information on hysterectomy. Physicians should be aware of the limitations and provide up-to-date and peer-reviewed content on the website.

Rapid dissemination of practice-changing information: A longitudinal analysis of real-world rates of minimally invasive radical hysterectomy before and after presentation of the LACC trial.

OBJECTIVE: Characterize change in rates of minimally invasive (MIS) radical hysterectomy after presentation of the LACC trial. METHODS: Longitudinal analysis of data from Vizient® database for surgically treated patients with invasive cervical cancer from April 2017-March 2019. Covariates studied included patient demographic and obesity categories, dates of LACC trial presentation and publication, and hospital characteristics. RESULTS: 2102 cervical cancer patients had surgery at 201 hospitals. Most were age 31-50 (51.2%), White (64.8%), and had public (49.2%) health insurance. Annual rates of MIS fell from 51.9% to 27.1% after the LACC trial presentation (RR 0.52, 95% CI 0.47, 0.58; p < 0.0001). Adjusting for within hospital correlation, the odds of MIS dropped by 13% per month (OR = 0.872 per month, 95% CI 0.852, 0.891; p < 0.001), without further change in rates of MIS after the peer-review publication (OR = 1.033 per month, 95% CI 0.897, 1.189; p = 0.65). Rates of MIS declined across all demographics (RR = 0.32-0.65; p < 0.01), except in morbidly obese women (RR = 0.90; p = 0.60). Applying mixed effects model, rates of MIS fell by 3% per month in morbidly obese women versus 18% per month if body mass index<40 kg/m2. NCCN member hospitals and hospitals with gynecologic oncology fellowship training programs significantly reduced rates of MIS radical hysterectomy faster, but not earlier, than other hospitals. CONCLUSIONS: Rates of MIS radical hysterectomy fell dramatically and pervasively after the LACC trial presentation, despite ongoing substantive controversy. Practice pattern changes were not significant in morbidly obese women.

Two-dimensional (2D) versus three-dimensional (3D) laparoscopy for vaginal cuff closure by surgeons-in-training: a randomized controlled trial.

BACKGROUND: Objective evidence is lacking as to the benefit of the addition of 3D vision to conventional laparoscopy in Gynecologic surgery. This study aims to compare 3-D visual system to traditional 2-D laparoscopic visualization for the laparoscopic closure of the vaginal cuff during total laparoscopic hysterectomy by surgeons-in-training [defined as senior OBGYN resident or Minimally Invasive Gynecologic Surgery (MIGS) fellow]. METHODS: 51 patients undergoing total laparoscopic hysterectomy at two tertiary care academic hospitals were randomized to two-dimensional or three-dimensional vision system with cuff closure performed by surgeons-in-training. The primary outcome was the time taken for vaginal cuff closure. Secondary outcomes included peri-operative outcomes and assessment of surgeon's perception of ease of cuff closure. RESULTS: 27 (52.9%) cases were allocated to cuff closure with the 2D system and 24 (47.1%) cases to closure with the 3D vision system. Patient baseline characteristics were similar between the vision systems. Mean vaginal cuff closure time was not significantly different between 2D and 3D vision (10.1 min for 2D versus 12 min for 3D, p = 0.31). An additional 24 s was added to cuff closure time with each 1 kg/m2 increase in BMI, after controlling for potential confounders (p = 0.003). There was no difference in the surgeon rating of ease of cuff closure between 2D and 3D. Peri-operative outcomes are similar among the two groups. CONCLUSION: We did not demonstrate any benefits of 3D vision system over conventional 2D for the task of laparoscopic vaginal cuff suturing performed by surgeons-in-training.

Variability in gynecologic case volume of obstetrician-gynecologist residents graduating from 2009 to 2017.

BACKGROUND: Residency training in obstetrics-gynecology has changed significantly over time, with residents expected to master an increasing number of surgical procedures. Residency operative case logs are tracked by the Accreditation Council for Graduate Medical Education, which sets case minimums for all procedures. In 2018, the Accreditation Council for Graduate Medical Education created a combined minimally invasive hysterectomy category and now requires graduating residents to complete a minimum of 70 minimally invasive hysterectomies. OBJECTIVES: The objectiges of the study were to evaluate the range of operative gynecological experience across graduating obstetrician-gynecologist residents in the United States and to estimate the number of residents able to meet new Accreditation Council for Graduate Medical Education minimum hysterectomy cases. STUDY DESIGN: Accreditation Council for Graduate Medical Education surgical case logs of graduating obstetrician-gynecologist residents from 2009 to 2017 were analyzed for case volume trends. RESULTS: The average total number of gynecological cases per resident decreased from 438.2 to 431.5 (P < .0001). Minimally invasive hysterectomy averages increased from 43.6 to 69.3 (P < .0001), a trend driven principally by an increase in total laparoscopic hysterectomies. Mean case log decreases were noted in invasive cancer (70.7 to 54.3), incontinence and pelvic floor (85.6 to 56.7), and total abdominal hysterectomies (74.4 to 42.9); (P < .0001 for all). Mean increases were seen in total laparoscopic (118.8 to 146.3) and operative hysteroscopy (68.6 to 77.1) cases (P < .0001 for all). The ratio of the 90th percentile to the 10th percentile of resident case logs showed substantial variation in surgical volume for all procedures, although this ratio decreased over time. Graduates who logged 70 minimally invasive hysterectomy cases were estimated to fall at the 51st percentile in 2017; this was down from the 91st percentile in 2009. CONCLUSION: Nationwide, graduates of obstetrician-gynecologist residency experience significant variability in their surgical training. Based on our extrapolation of Accreditation Council for Graduate Medical Education data, approximately half of residency graduates fell below the 70 case minimally invasive hysterectomy minimum in 2017. Meeting the new Accreditation Council for Graduate Medical Education hysterectomy minimums may be challenging for a significant proportion of residency programs. Understanding the scope and variability of gynecology training is needed to continue to improve and address gaps in resident education.

Three-Dimensional Peripheral Bloodstream Model of the Uterus for Laparoscopic Radical Hysterectomy.

Trainees require extensive experience to perform radical hysterectomy. Before starting training during an actual operation, trainees should be familiar with the pelvic anatomy and should simulate surgical procedures. Many simulators are available for virtual reality training of laparoscopic operations, but they are very expensive. The materials required to construct our model included sponges and colored wires sold in home improvement stores that allowed for superior cost effectiveness. The model represented almost all peripheral vessels and nerves around the uterus, including the minor vessels. Attaching and detaching the vessels was easy, facilitating reconstruction of the dissected vessels. The wires were easy to bend, ensuring high operability. This model allows for the simulation of laparoscopic radical hysterectomy in a dry box. Our model was superior to a 2-dimensional picture for the memorization of branching and positional relationships of the blood vessels. Comparison of our model with actual operative videos showed that the dry box provided an identical surgical view of an actual laparoscopic radical hysterectomy. We developed a peripheral bloodstream model of the uterus for repeated simulation of laparoscopic radical hysterectomy with an actual surgical view using a dry box.

Simulator training and residents' first laparoscopic hysterectomy: a randomized controlled trial.

BACKGROUND: Hysterectomy rates are decreasing in many countries, and virtual reality simulators bring new opportunities into residents' surgical education. The objective of this study was to evaluate the effect of training in laparoscopic hysterectomy module with virtual reality simulator on surgical outcomes among residents performing their first laparoscopic hysterectomy. METHODS: This randomized study was carried out at the Department of Obstetrics and Gynecology in Helsinki University Hospital and Hyvinkää Hospital. We recruited twenty residents and randomly signed half of them to train ten times with the laparoscopic hysterectomy module on a virtual reality simulator, while the rest represented the control group. Their first laparoscopic hysterectomy was video recorded and assessed later by using the Objective Structured Assessment of Technical Skills (OSATS) forms and Visual Analog Scale (VAS). The scores and surgical outcomes were compared between the groups. RESULTS: The mean OSATS score for the Global Rating Scale (GRS) was 17.0 (SD 3.1) in the intervention group and 11.2 (SD 2.4) in the control group (p = 0.002). The mean procedure-specific OSATS score was 20.0 (SD 3.3) and 16.0 (SD 2.8) (p = 0.012), and the mean VAS score was 55.0 (SD 14.8) and 29.9 (SD 14.9) (p = 0.001). Operative time was 144 min in the intervention group and 165 min in the control group, but the difference did not reach statistical significance (p = 0.205). There were no differences between the groups in blood loss or direct complications. CONCLUSION: Residents training with a virtual reality simulator prior to the first laparoscopic hysterectomy seem to perform better in the actual live operation. Thus, a virtual reality simulator hysterectomy module could be considered as a part of laparoscopic training curriculum.

Learning curve of high-complexity surgery for advanced ovarian cancer.

OBJECTIVE: We investigated the learning curve for a monodisciplinary surgical team consisting of gynecologic oncologists performing cytoreductive surgery for advanced ovarian cancer, involving high-complexity procedures with bowel resection and upper abdominal surgery. METHODS: We investigated 271 consecutive patients with ovarian, fallopian tube, and peritoneal carcinoma undergoing cytoreductive surgery for stage III/IV disease. All operations were performed by a team consisting of only gynecologic oncologists. Patients were classified into 2 groups depending on the surgical complexity score (a cumulative score based on complexity and number of procedures performed). Learning curves for patients with moderate (4-7, 63 patients) and high scores (8-18, 208 patients) were evaluated using cumulative sum (CUSUM) analysis of operative time, total blood loss, and perioperative complications. RESULTS: Operative time and total blood loss showed a learning curve. The CUSUM curve for operative time peaked at the 28th and 51st case in the moderate- and high-score groups, respectively. The CUSUM curve for total blood loss peaked at the 16th and 55th case in the moderate- and high-score groups, respectively. The CUSUM curve for complications (Clavien-Dindo ≥ IIIb) showed a downward slope after the 6th case in the high-score group and remained within the acceptable range throughout the study. CONCLUSION: Proficiency in performing high-complexity surgery was achieved after approximately 50 cases and this number is greater than the number of cases required to perform moderate-complexity surgery. Acceptable rates of severe perioperative complications were observed even during the initial learning period in cases of high-complexity surgery.

The Impact of Systematic Laparoscopic Skills and Suture Training on Laparoscopic Hysterectomy Outcomes in a Brazilian Teaching Hospital.

OBJECTIVE: To evaluate the impact of systematic laparoscopic skills and suture training (SLSST) on the total laparoscopic hysterectomy intra- and postoperative outcomes in a Brazilian teaching hospital. METHODS: A cross-sectional observational study in which 244 charts of total laparoscopic hysterectomy (TLH) patients operated from 2008 to 2014 were reviewed. Patient-specific (age, parity, previous cesarean sections, abdominal surgeries and endometriosis) and surgery-related variables (hospital stay, operative time, uterine volume and operative complications) were analyzed in three different time-frame groups: 2008-09 (I-1) - TLHs performed by senior attending physicians; 2010-11 (I-2) - TLHs performed by residents before the implementation of the SLSST program; and 2012-14 (I-3) - TLHs performed by residents after the implementation of the SLSST program. RESULTS: A total of 244 TLH patients (mean age: 45.93 years) were included: 24 (I-1), 55 (I-2), and 165 (I-3). The main indication for TLH was uterine myoma (66.4%). Group I-3 presented a decrease in surgical time compared to group I-2 (p = 0.010). Hospital stay longer than 2 days decreased in group I-3 compared to group I-2 (p = 0.010). Although we observed decreased uterine volume (154.2 cm3) in group I-2 compared to group I-1 (217.8 cm3) (p = 0.030), logistic regression did not find any association between uterine volume and surgical time (p = 0.103). CONCLUSION: The total operative time for laparoscopic hysterectomy was significantly shorter in the group of patients (I-3) operated after the systematic laparoscopic skills and suture training was introduced in our hospital.

OBJETIVO: Avaliar o impacto do treinamento laparoscópico sistematizado de habilidades e sutura (TLSHS) nos resultados intra e pós-operatórios da histerectomia laparoscópica em um hospital universitário brasileiro. MéTODOS: Estudo observacional transversal de revisão de 244 prontuários de pacientes submetidas a histerectomia total laparoscópica (HTL) operadas entre 2008 e 2014. Os fatores específicos das pacientes (idade, paridade, cesariana prévia, cirurgias abdominais, e endometriose) e as variáveis relacionadas à cirurgia (tempo de hospitalização, tempo de cirurgia, volume uterino e complicações operatórias) foram analisados em três grupos temporais: 2008-09 (I-1) ­ HTLs realizadas por médicos experientes; 2010-11 (I-2) ­ HTLs realizadas por residentes sem TLSHS; 2012-2014 (I-3) ­ HTLs realizadas por residentes após a implementação do TLSHS. RESULTADOS: Um total de 244 pacientes submetidas a HTLs foram incluídas (média de idade de 45,93 anos): 24 operadas no período I1, 55 no I2, e 165 no I3. A principal indicação para HTL foi mioma uterino (66,4%). O grupo I-3 apresentou diminuição no tempo cirúrgico quando comparado ao grupo I-2 (p = 0,010). Hospitalização superior a 2 dias diminuiu no grupo I-3 comparado ao grupo I-2 (p = 0,010). Apesar de observarmos diminuição no volume uterino dos pacientes do grupo I-2 (154,2 cm3) em comparação com os do grupo I-1 (217,8 cm3) (p = 0,030), a regressão logística não revelou associação entre volume uterino e tempo cirúrgico (p = 0,103). CONCLUSãO: O tempo cirúrgico na HTL foi significativamente menor no grupo de pacientes submetidas à cirurgia após a implantação do TLSHS em nosso hospital.

The impact of systematic laparoscopic skills and suture training on laparoscopic hysterectomy outcomes in a brazilian teaching hospital / O impacto do treinamento laparoscópico sistematizado de habilidades e sutura nos resultados da histerectomia laparoscópica em hospital universitário brasileiro

Abstract Objective To evaluate the impact of systematic laparoscopic skills and suture training (SLSST) on the total laparoscopic hysterectomy intra- and postoperative outcomes in a Brazilian teaching hospital. Methods A cross-sectional observational study in which 244 charts of total laparoscopic hysterectomy (TLH) patients operated from 2008 to 2014 were reviewed. Patient-specific (age, parity, previous cesarean sections, abdominal surgeries and endometriosis) and surgery-related variables (hospital stay, operative time, uterine volume and operative complications) were analyzed in three different time-frame groups: 2008-09 (I-1) - TLHs performed by senior attending physicians; 2010-11 (I-2) - TLHs performed by residents before the implementation of the SLSST program; and 2012-14 (I-3) - TLHs performed by residents after the implementation of the SLSST program. Results A total of 244 TLH patients (mean age: 45.93 years) were included: 24 (I-1), 55 (I-2), and 165 (I-3). The main indication for TLH was uterine myoma (66.4%). Group I-3 presented a decrease in surgical time compared to group I-2 (p=0.010). Hospital stay longer than 2 days decreased in group I-3 compared to group I-2 (p=0.010). Although we observed decreased uterine volume (154.2 cm3) in group I-2 compared to group I-1 (217.8 cm3) (p=0.030), logistic regression did not find any association between uterine volume and surgical time (p=0.103). Conclusion The total operative time for laparoscopic hysterectomy was significantly shorter in the group of patients (I-3) operated after the systematic laparoscopic skills and suture training was introduced in our hospital.

Resumo Objetivo Avaliar o impacto do treinamento laparoscópico sistematizado de habilidades e sutura (TLSHS) nos resultados intra e pós-operatórios da histerectomia laparoscópica em um hospital universitário brasileiro. Métodos Estudo observacional transversal de revisão de 244 prontuários de pacientes submetidas a histerectomia total laparoscópica (HTL) operadas entre 2008 e 2014. Os fatores específicos das pacientes (idade, paridade, cesariana prévia, cirurgias abdominais, e endometriose) e as variáveis relacionadas à cirurgia (tempo de hospitalização, tempo de cirurgia, volume uterino e complicações operatórias) foram analisados em três grupos temporais: 2008-09 (I-1) - HTLs realizadas por médicos experientes; 2010-11 (I-2) - HTLs realizadas por residentes sem TLSHS; 2012-2014 (I-3) - HTLs realizadas por residentes após a implementação do TLSHS. Resultados Um total de 244 pacientes submetidas a HTLs foram incluídas (média de idade de 45,93 anos): 24 operadas no período I1, 55 no I2, e 165 no I3. A principal indicação para HTL foi mioma uterino (66,4%). O grupo I-3 apresentou diminuição no tempo cirúrgico quando comparado ao grupo I-2 (p=0,010).

Conclusão O tempo cirúrgico na HTL foi significativamente menor no grupo de pacientes submetidas à cirurgia após a implantação do TLSHS em nosso hospital.

Learning curve analysis of transvaginal natural orifice transluminal endoscopic hysterectomy.

BACKGROUND: No data are available to assess the learning curve for transvaginal natural orifice transluminal endoscopic hysterectomy for non-prolapsed uteri in benign gynecologic diseases. The lack of exposure to transvaginal natural orifice transluminal endoscopic hysterectomy during training, in addition to a poorly defined learning curve, further deters interested physicians from applying this technique to daily practice. The aim of this study was to evaluate the learning curve and perioperative outcome of transvaginal natural orifice transluminal endoscopic hysterectomy by an experienced endoscopist. METHODS: A total of 240 cases of transvaginal natural orifice transluminal endoscopic hysterectomies with or without adnexectomy for various benign gynecologic diseases were included. Demographic data and various perioperative parameters were reviewed from the prospectively collected database. Operative time was set as a surrogate marker for surgical competency. The learning curve was evaluated using the cumulative sum method. RESULTS: The overall mean operative time (OT) was 76.5 min ± 22.4. Four unique phases of the learning curve were derived using cumulative sum analysis: the mean OT of phase I (the initial learning curve of 20 cases) was 86.3 ± 23.7 min, phase II (acquisition of competence of 80 cases) was 71.0 ± 21.4 min, phase III (proficiency and plateau of 80 cases) was 76.0 ± 20.4 min, and phase IV (post-learning in which more challenging cases were managed) was 81.3 ± 23.6 min. No major complications were encountered. One case in phase III converted to laparoscopy due to difficulty in performing anterior colpotomy. CONCLUSION: Our data demonstrated four distinct phases of the learning curve of transvaginal natural orifice transluminal endoscopic hysterectomy. In a well-trained endoscopist, surgical competence in transvaginal natural orifice transluminal endoscopic hysterectomy can be reached after 20 cases.
