RESUMO
STUDY OBJECTIVE: To compare the rate of postoperative urinary retention (POUR) after total laparoscopic hysterectomy (TLH) using the autofill vs the backfill void trial. Secondary objectives were to compare the time to discharge from the recovery room, rate of postoperative urinary tract infection (UTI), perceived bladder condition, the effect of bladder function on life, and patient satisfaction. DESIGN: Randomized controlled trial. SETTING: Single academic medical center. PATIENTS: Women who underwent TLH by conventional laparoscopy or robotic-assisted laparoscopy for benign non-urogynecologic indications. INTERVENTIONS: After TLH, participants were randomized to have an autofill void trial (group A) or a backfill void trial once they were able to ambulate (group B). Failure rate, time to discharge, and UTI rate were assessed. Participants completed the patient perception of bladder condition and the incontinence impact questionnaire-short form questionnaires. Patient satisfaction was assessed. Multiple regression analysis was performed to determine the predictors of POUR. MEASUREMENTS AND MAIN RESULTS: Eighty-two participants completed the study after randomization, 42 in group A and 40 in group B. There were no statistically significant differences in demographic or perioperative outcomes. Seven participants had POUR in group A (16.7%) and 11 in group B (27.5%) (pâ¯=â¯.36), respectively. The median time to discharge was 176 minutes for group A (160.5, 255.5) and 218 minutes for group B (180, 265) (pâ¯=â¯.01), respectively. There were no statistically significant differences in rate of postoperative UTI (pâ¯>.99), patient perception of bladder condition scores (pâ¯=â¯.24), incontinence impact questionnaire-short form scores (pâ¯=â¯.23), and patient satisfaction scores (pâ¯=â¯.26). A stepwise logistic regression analysis did not demonstrate any predictors of POUR. CONCLUSION: Backfill void trial once the participant was able to ambulate was not superior to the autofill void trial with respect to the rate of POUR. The autofill void trial resulted in faster same-day discharge.

STUDY QUESTION: Is there perfusion to the fallopian tubes in ex-vivo and in-vivo uteri at the time of total laparoscopic hysterectomy (TLH), as observed using laser angiography with indocyanine green (ICG)? SUMMARY ANSWER: The fallopian tubes may have perfusion from the utero-ovarian vasculature alone. WHAT IS KNOWN ALREADY: The fallopian tubes are perfused by the uterine and utero-ovarian vessels. Perfusion can be measured using laser angiography with ICG. STUDY DESIGN, SIZE, DURATION: This prospective pilot cohort study included 15 women, ages 32-59 years old, who underwent TLH with bilateral salpingectomy for benign indications. PARTICIPANTS/MATERIALS, SETTING, METHODS: In five participants, TLH was performed and the utero-ovarian artery was cannulated ex vivo and injected with ICG. The other 10 participants underwent the in-vivo protocol. The mesosalpinx and uterine vessels were transected in the partial protocol. Colpotomy was also performed in the complete protocol. All fallopian tubes were imaged using laser angiography with ICG. The relative fluorescence and the fluorescence intensity ratio (length of fluorescent fallopian tube/total length of fallopian tube) of the fallopian tubes were measured in the ex-vivo and in-vivo protocols, respectively. MAIN RESULTS AND THE ROLE OF CHANCE: Ex vivo, the fimbria of the ipsilateral fallopian tube had 47% median relative fluorescence as compared to the contralateral fallopian tube, which had 2.4% median relative fluorescence. In vivo, the post-ICG fluorescence intensity ratios were 0.61 ± 0.40 for the partial protocol, and 0.78 ± 0.30 for the complete protocol, with mean differences of 0.37 (95% CI: 0.23-0.50, P < .0001) and 0.22 (95% CI: 0.12-0.31, P < 0.0001), respectively, between the pre-procedure and the post-ICG fluorescence intensity ratios. Greater than 0.75 fluorescence intensity ratios (i.e. >75% tubal length fluorescence) was seen in 60% of fallopian tubes. LIMITATIONS, REASONS FOR CAUTION: This is a pilot study with a small sample size and pathologic uteri, which would not be appropriate for uterine transplantation. No conclusions can be made regarding the functionality of the fallopian tubes. WIDER IMPLICATIONS OF THE FINDINGS: The fallopian tubes may have perfusion with the utero-ovarian vasculature alone, potentially allowing for future animal studies regarding tubal viability in recipients of uterine-tubal transplants. If successful, human uterine-tubal transplantation may allow for spontaneous conception rather than IVF. STUDY FUNDING/COMPETING INTEREST(S): No external funding was used.

Surgical adhesions can lead to significant consequences including abdominopelvic pain, bowel obstruction, subfertility, and subsequent surgery. Although laparoscopic surgery is associated with a decreased risk of adhesion formation, methods to further decrease adhesions are warranted. We systematically reviewed literature addressing the management, prevention, and sequelae of adhesions in women undergoing laparoscopic gynecologic surgery. We searched PubMed, EMBASE, EBSCOhost, and Cochrane Central Register of Controlled Trials and found 6566 records. The primary outcome was adhesion formation. The secondary outcomes were abdominopelvic pain, quality of life, subfertility, pregnancy, bowel obstruction, urinary symptoms, and subsequent surgery. After applying inclusion and exclusion criteria, 52 studies remained for qualitative synthesis. Risk of bias assessments were applied independently by 2 authors. There was evidence that Hyalobarrier Gel (Anika Therapeutics, Bedford, MA), HyaRegen NCH Gel (Bilar Medikal, Istanbul, Turkey), Oxiplex/AP Gel (Fziomed, Inc., San Luis Obispo, CA), SprayGel (Confluent Surgical Inc., Waltham, MA), and Beriplast (CSL Behring, LLCm King of Prussia, PA) all decrease the incidence of adhesions. Adept (Baxter, Deerfield, IL) significantly decreased de novo adhesion scores of the posterior uterus. Using an integrated treatment approach to pelvic pain significantly improved pain and quality of life compared with standard laparoscopic treatment. Lastly, Hyalobarrier Gel Endo (Anika Therapeutics, Bedford, MA) placement led to a higher pregnancy rate than no barrier usage. Our findings underscore the need for high-quality trials to evaluate the efficacy of surgical techniques, adhesion barriers, and other treatment modalities on the management and prevention of adhesions and their clinical sequelae. This review was registered on PROSPERO (ID = CRD42017068053).

STUDY OBJECTIVE: Uterine transplantation has proven feasible since the first live birth reported in 2014. To enable attachment of the uterus in the recipient, long vascular pedicles of the uterine and internal iliac vessels were obtained during donor hysterectomy, which required a prolonged laparotomy to the living donors. To assist further attempts at uterine transplantation, our video serves to review literature reports of internal iliac vein anatomy and demonstrate a laparoscopic dissection of cadaver pelvic vascular anatomy. DESIGN: Observational (Canadian Task Force Classification III). SETTING: Academic anatomic laboratory. Institutional Review Board ruled that approval was not required for this study. INTERVENTION: Literature review and laparoscopic dissection of cadaveric pelvic vasculature, focusing on the internal iliac vein. MEASUREMENTS AND MAIN RESULTS: Although the internal iliac artery tends to have minimal anatomic variation, its counterpart, the internal iliac vein, shows much variation in published studies [1,2]. Relative to the internal iliac artery, the vein can lie medially or laterally. Normal anatomy is defined as some by meeting 2 criteria: bilateral common iliac vein formed by ipsilateral external and internal iliac vein at a low position and bilateral common iliac vein joining to form a right-sided inferior vena cava [2]. Reports show 79.1% of people have normal internal iliac vein anatomy by these criteria [2]. The cadaver dissection revealed internal iliac vein anatomy meeting criteria for normal anatomy. CONCLUSION: Understanding the complexity and variations of internal iliac vein anatomy can assist future trials of uterine transplantation.

OBJECTIVE: To develop a realistic simulation model for performance of laparoscopic colpotomy and evaluate its construct and face validity. METHODS: A simulation model was developed and constructed using polyvinyl chloride piping, a uterine manipulator, and synthetic vaginal tissue paired with a commercially available laparoscopic trainer. An observational study was conducted to validate the simulation model for use as a teaching tool. Construct validity was measured through performance evaluation of novice and expert surgeons using a standard and modified Global Operative Assessment of Laparoscopic Skills scale with possible score ranges of 5-25 and 5-40, respectively. Expert surgeons included attending surgeons across various gynecologic subspecialties who teach total laparoscopic hysterectomy to trainees and perform more than 50 total laparoscopic hysterectomies annually. Novice surgeons included residents who perform total laparoscopic hysterectomy as part of their training. Standards were set using a modified contrasting groups approach. Interrater reliability was calculated using Kendall's τ correlation coefficient. Participants were surveyed regarding the realism of the model and its utility as a teaching tool to assess face validity. RESULTS: Five expert and 15 novice surgeons volunteered to participate. Expert surgeons scored higher than novice surgeons on the Global Operative Assessment of Laparoscopic Skills scale (22.8±1.52 vs 13.53±2.69, respectively) with a mean difference of 9.27 (95% CI 7.12-11.4, P<.01) and on a modified Global Operative Assessment of Laparoscopic Skills scale (36.9±2.19 vs 22.6±3.95, respectively) with a mean difference of 14.30 (95% CI 11.2-17.4, P<.01). Suggested passing range was set at 30.5-32.5 out of 40 total points. Kendall's τ interrater reliability was 0.86 (95% CI 0.798-0.923) and 0.87 (95% CI 0.818-0.922), respectively. All participants agreed that the training model was useful for teaching and learning laparoscopic colpotomy and for assessing the learner's ability to perform colpotomy before live surgery. CONCLUSION: This validated simulation system offers novice surgeons an opportunity to practice the skill set necessary to perform laparoscopic colpotomy efficiently and may be used as an educational tool.
