Decline in surgeon volume after successful implementation of advanced laparoscopic surgery in gynecology: An undesired side effect?

Vaginal assisted NOTES hysterectomy in The Netherlands; A prospective cohort study

Objectives

Vaginal assisted Natural Orifice Transluminal Endoscopic Surgery (NOTES) combines the benefits of vaginal and endoscopic surgery. This study presents the results of the first vaginal assisted NOTES hysterectomies (VANH) in The Netherlands.

Study design

A prospective cohort study was performed in two non-academic teaching hospitals in The Netherlands. Data was collected from patients who underwent a VANH for benign indications between August 2019 and April 2023. Baseline characteristics and data of intra- and postoperative surgical outcomes were recorded and analysed. The VANHs were performed by four experienced vaginal and endoscopic gynaecological surgeons.

Results

A total of 200 patients underwent a VANH. Indications were dysfunctional menstrual bleeding (61 %; n = 122), abnormal cervical cytology (15.5 %; n = 31), abdominal pain (11.5 %; n = 23), post ablation/sterilization pain syndrome (3.5 %; n = 7), uterine fibroids (5.0 %; n = 10), atypical endometrial hyperplasia (2.5 %; n = 5) and Lynch or BRCA gene mutation carriers (1.0 %, n = 2). The mean surgical time was 61.4 min ( ± 22.8 min) with a mean blood loss of 88 mL ( ± 89 mL) and a mean uterine weight of 150 g ( ± 112 g). In 2.0 % (n = 4) of the cases a conversion was necessary. Same day discharge (SDD) was feasible in 80.2 % (n = 105) of the patients planned in day-care. In 2.0 % (n = 4) an intra-operative complication and in 9.0 % (n = 18) a post-operative complication occurred.

Conclusion

This study shows vNOTES to be a safe and feasible surgical technique and can be safely implemented with appropriate patient selection and skilled surgeons. It highlights the importance of surgeon awareness of the challenges inherent in the initial stages of the implementation of a new surgical technique when performing their first vNOTES procedures. Additional randomized clinical trials are needed to show superiority of vNOTES compared to traditional surgery.

Same-day discharge after laparoscopic hysterectomy for benign/premalignant disease: A multicentre randomised controlled trial

OBJECTIVE

To evaluate whether physical function and quality of life was influenced by discharge on the same-day after a total laparoscopic hysterectomy.

DESIGN

Multicentre non-inferiority randomised controlled trial.

SETTING

Five teaching hospitals and two university hospitals in the Netherlands.

POPULATION

Patients undergoing laparoscopic hysterectomy for benign or premalignant disease.

METHODS

Following informed consent, participants were allocated 1:1 either to same-day discharge (SDD) or next-day discharge (NDD).

MAIN OUTCOME MEASURES

The primary outcome was physical function at 7 days after surgery measured by the Patient Reported Outcomes Measurement Information System (PROMIS) Physical Function short Form 10A. Secondary outcomes were physical function and quality of life at 1 and 3 days and 6 weeks after surgery measured with PROMIS short Form 10A and the EuroQol questionnaire (EQ-5D-5L).

RESULTS

Two hundred and five patients were included of whom 105 were allocated to SDD and 100 to NDD. Physical function 7 days after surgery was 35.95 in the SDD group and 35.63 in the control group (mean difference 0.32; 95% CI [0.07-0.57]). As the upper limit of the 95% CI does not exceed the non-inferiority margin of 4 points, non-inferiority of SDD could be demonstrated. No difference in physical function nor quality of life on Days 1 and 3 and 6 weeks could be found.

CONCLUSION

This research demonstrates same-day discharge after laparoscopic hysterectomy is non-inferior to next day discharge in physical function 7 days after surgery.

Prospective Cohort Study Quantifying the Effect of the LevaLap 1.0 on the Distance between the Abdominal Wall and Intra-abdominal Viscera

STUDY OBJECTIVE

More than 13 million laparoscopic procedures are performed globally every year. The LevaLap 1.0 device may facilitate safe abdominal access when using the Veress needle for initial abdominal insufflation during laparoscopic surgery. We undertook this study to test the hypothesis that use of the LevaLap 1.0 would increase the distance from the abdominal wall to underlying viscera and the retroperitoneum, including from major vessels.

DESIGN

Prospective cohort study.

SETTING

Referral center.

PATIENTS

Eighteen patients scheduled to undergo an interventional radiology procedure under general anesthesia and muscle relaxation.

INTERVENTIONS

Application of the LevaLap 1.0 device on the umbilicus and on Palmer's point, during computed tomography scanning.

MEASUREMENTS

Distance from the abdominal wall to the underlying bowel and to retroperitoneal blood vessels and more distant intra-abdominal organs before and after vacuum was applied to the LevaLap 1.0.

MAIN RESULTS

The device did not significantly increase the distance from the abdominal wall to the immediate underlying bowel. Alternatively, the LevaLap 1.0 created a significant increase in the distance between the abdominal wall at the access point and more distant intra-abdominal organs at the umbilicus and at Palmer's point (mean ± SD: +3.91 ± 2.32 cm, p = .001, and +3.41 ± 3.12 cm, p = .001, respectively). At the umbilicus, the device increased the distance between the abdominal wall and the anterior wall of the vena cava by +5.32 ± 1.22 cm (p = .004) or the anterior wall of the aorta by 5.49 ± 1.40 cm (p = .004). At Palmer's point, the device increased the distance between the anterior abdominal wall and the colon and/or small bowel by 2.13 ± 1.81 cm (p = .023). No adverse events were reported.

CONCLUSIONS

The LevaLap 1.0 increased the distance between abdominal wall and major retroperitoneal blood vessels by >5 cm, promoting safer access during Veress needle insufflation when performing laparoscopic surgery.

The Endourological Society Inaugural Census Report

The Endourological Society, the premier urologic society encompassing endourology, robotics, and focal surgery, is composed of a diverse group of >1300 urologists. However, limited information has been collected about society members. Recognizing this need, a survey was initiated to capture data regarding current member practices, as well as help the Society shape the future direction of the organization. Presented herein is the inaugural Endourological Society census report as the beginning of a continued effort for global improvement in the field of endourology. Using a REDCap^® database, an email survey was circulated to the membership of the Endourological Society from May through June 2021. Twenty questions were posed, categorizing member data in terms of epidemiology/demographics, practice patterns, member opinions, and future educational preferences. Responses were received from 534 members, representing 40.3% of membership. Data demonstrated that the average age, gender, race, and ethnicity of the typical Society member respondent is a 48-year-old Caucasian male working in the United States, with a mean of 25 years in practice. Retrograde endoscopy and percutaneous nephrolithotomy were identified as the most common practice skills, and 50% of members are involved in robotics. Importantly, the census confirmed that the World Congress of Endourology and Technology remains popular with Society members as a means of educational advancement. To sustain and advance the Society, information is required to understand the career interests and future educational desires of its members. This inaugural census provides crucial data regarding its membership and how the Society can achieve continued success and adjust its focus. Future census efforts will expand on the initial findings and stratify the data to elucidate changes in the needs of the Society as a whole. Circulating an annual census will allow for continued improvements in the field of endourology and, ultimately, better care for urologic patients.

Vaginal hysterectomy versus vaginal assisted NOTES hysterectomy (VANH): a protocol for a randomised controlled trial

Introduction

Natural Orifice Transluminal Endoscopic Surgery is a minimal invasive technique using natural body orifices like the vagina. Benefits of a vaginal assisted NOTES hysterectomy (VANH) are no visible scars, less blood loss, shorter surgery time and it allows more women to undergo a hysterectomy in a day-care setting compared with the total laparoscopic hysterectomy. Trials comparing vaginal hysterectomy (VH) and VANH are lacking. The aim of this study is to compare hysterectomy by VANH versus VH for same-day discharge (SDD), complications, surgical outcomes, postoperative recovery, quality of life, costs and cost-effectiveness.

Methods and analysis

The study is a single-blinded, multicentre, randomised controlled trial. Eligible women with benign indication for hysterectomy will be randomly allocated to the VH (control) group or the VANH (intervention) group. The primary outcome is SDD. We calculated a sample size of 124 women assuming 27% SDD difference with an alpha of 0.05 and power of 0.8. A total of 83 patients will be included in the VANH-group and 41 patients in the VH-group, using an enrolment ratio of 2:1. Secondary outcomes are; surgery-related complications, surgical outcomes, postoperative recovery, quality of life, costs and cost-effectiveness.

Ethics and dissemination

The study was approved on 27 May 2021 by the Ethics Committee of the Zuyderland Medical Centre Heerlen. The first patient was randomised on 8 July 2021. The last participant randomised should be treated before 31 December 2022. The results will be presented in peer-reviewed journals and at scientific meetings within 4 years after starting recruitment.
