Comparison of Trendelenburg Angles in Vaginal, Laparoscopic, and Robotic Uterovaginal Apical Prolapse Repairs.

STUDY OBJECTIVE: To compare the Trendelenburg angle used in laparoscopic uterovaginal apical prolapse repairs with the angles used in vaginal and robotic uterovaginal apical prolapse repairs. DESIGN: Prospective, multicenter cohort study from May 2015 to December 2016. SETTING: Two academic teaching hospitals. PATIENTS: Sixty patients who underwent vaginal high uterosacral ligament suspension, laparoscopic sacrocolpopexy, or robotic sacrocolpopexy performed by 6 surgeons board-certified in female pelvic medicine and reconstructive surgery. INTERVENTIONS: Measurement of Trendelenburg angle and time spent in Trendelenburg during surgery. MEASUREMENTS AND MAIN RESULTS: Twenty patients were enrolled in each procedure group. The median maximum angle of Trendelenburg was significantly greater in the laparoscopic group (22° [20-25]) than in the vaginal group (15° [6-19]; p <.001) and the robotic group (19° [16-21]; p = .02). The participants in the laparoscopic group spent significantly more time overall in Trendelenburg (176 minutes [143-221]) than those in the robotic group (150 minutes [127-161]; p = .01) and those in the vaginal group (120 minutes [86-128]; p <.001). The participants in the laparoscopic and robotic groups spent similar amounts of time in maximum Trendelenburg (116 minutes [52-164] and 117 minutes [61-134], respectively; p = .56), whereas the participants in the vaginal group spent significantly less time in maximum Trendelenburg (10 minutes [7-38]) than those in the laparoscopic group (p <.001). The total median operative time was highest for the laparoscopic approach (211 minutes [173-270]), followed by the robotic approach (181 minutes [165-201]) and the vaginal approach (162 minutes [128-186]; p = .008). CONCLUSION: The median maximum angle of Trendelenburg was highest in laparoscopic sacrocolpopexy-followed by robotic sacrocolpopexy-and lowest in vaginal high uterosacral ligament suspension. Patients who underwent robotic sacrocolpopexy spent less time in Trendelenburg than those who underwent the laparoscopic approach. Prolonged, steep Trendelenburg is often not required for any of the 3 surgical procedures, but a vaginal approach should be considered for those at high risk of complications from Trendelenburg position.

A Telephone Call to Decrease Patient Anxiety Before Urodynamic Testing: A Randomized Controlled Trial.

OBJECTIVE: The aim of this study was to determine if a telephone call before undergoing urodynamic study (UDS) would decrease test-related anxiety compared with standard care. METHODS: We performed a randomized controlled trial at a single practice from April 2016 to June 2017. Patients at least 18 years old with lower urinary tract dysfunction and undergoing UDS for the first time were eligible. All participants received standard counseling; participants randomized to the intervention group also received a telephone call before their UDS appointment to answer any questions regarding their upcoming test. All participants completed surveys before and after testing to assess anxiety, preparedness, and satisfaction. The primary outcome was anxiety level immediately before UDS. Secondary outcomes included self-reported patient preparedness, pain, and satisfaction with counseling. Data were compared using χ, Fisher exact, and Wilcoxon rank sum tests. RESULTS: One hundred two participants were included in this as-treated analysis: 52 in the intervention group and 50 in the standard care group. The 2 groups were similar in age, ethnicity, and the proportion seeking additional information before testing. There were no statistically significant differences between groups with respect to overall anxiety, anxiety regarding specific elements of the test, or anticipated pain (all P ≥ 0.19). Participant satisfaction with pre-UDS counseling was significantly higher in the intervention group (80.8%) compared with the standard care group (54.0%; P = 0.002). CONCLUSIONS: Our study showed that a telephone call before undergoing UDS did not decrease anxiety compared with standard care; however, the telephone call was associated with higher satisfaction with pre-UDS counseling.

Opioid use following gynecologic and pelvic reconstructive surgery.

INTRODUCTION AND HYPOTHESIS: Opioid use, addiction, and overdose are a growing epidemic in the USA. Our objective was to determine whether the amount of opioid medication prescribed following gynecologic and pelvic reconstructive surgery is insufficient, adequate, or in excess. We hypothesized that we were overprescribing postoperative opioids. METHODS: Participants who were at least 18 years old and underwent gynecologic and/or pelvic reconstructive surgery from April through August 2016 were eligible to participate. Routine practice for pain management is to prescribe 30 tablets of opioids for major procedures and ten to 15 tablets for minor procedures. At the 2-week postoperative visit, participants completed a questionnaire regarding the number of tablets prescribed and used, postoperative pain control, and relevant medical history. Fisher's exact test was used to compare data. RESULTS: Sixty-five participants completed questionnaires. Half (49.1%) reported being prescribed more opioids than needed, while two (3.5%) felt the amount was less than needed. Though not significant, participants who underwent major surgeries were more likely to report being prescribed more than needed (53.5%) compared with participants who underwent minor surgeries (35.7%; p = 0.47). Though not significant, participants with anxiety were less likely to report being prescribed more tablets than needed compared with participants without anxiety (44.4% vs. 57.1%; p = 0.38). This was also true of participants with depression compared with those without (37.5% vs. 58.3%; p = 0.17), and those with chronic pain compared with those without (33.3% vs. 60.0%; p = 0.10). CONCLUSIONS: Our current opioid prescription practice for postoperative pain management may exceed what patients need.

Improved adequacy of endometrial tissue sampled from postmenopausal women using the MyoSure Lite hysteroscopic tissue removal system versus conventional curettage.

OBJECTIVE: To compare the diagnostic suitability of endometrial tissues obtained from postmenopausal women using the MyoSure Lite tissue removal system versus conventional curettage. MATERIALS AND METHODS: Endometrial tissue was sampled in hysteroscopically normal extirpated uteri from seven postmenopausal women (65.9±6.6 years old) using both hysteroscopicguided morcellation and curettage (two quadrants/uterus with each method). Endometrial sampling was performed immediately after hysterectomy for benign reasons unrelated to uterine pathology. Retrieved endometrial tissue samples were evaluated for volume and diagnostic suitability by a pathologist who was masked to the sampling technique used. RESULTS: Endometrial tissue sampling times were similar for morcellation (44±23 s) and curettage (47±38 s). Mean tissue volume retrieved with MyoSure (1,411±775 mm3) was significantly greater than with curettage (1±2 mm3; p=0.0004, two-tailed t-test), with larger intact tissue fragments retrieved with morcellation. Both specimen volume and quality obtained by MyoSure Lite were deemed to be significantly better for histologic assessment than the tissues obtained with curettage (p=0.0006 by Fisher's exact test and p=0.0137 by chi-square test, respectively). With dilation and curettage, samples were frequently too scanty for evaluation. Diagnostic concurrence between MyoSure Lite/dilation and curettage samples and histopathology of full-thickness samples taken afterward was also significantly better with MyoSure Lite than with curettage (p=0.0210). CONCLUSION: Endometrial tissue sampling using the minimally invasive MyoSure Lite hysteroscopic tissue removal system may provide larger volumes of higher-quality endometrial tissue specimens for pathology assessment compared to specimens obtained using conventional curettage, in postmenopausal women.

Risk Factors for Surgical Site Infection in Patients Undergoing Sacral Nerve Modulation Therapy.

OBJECTIVES: The aim of this study was to identify risk factors for surgical site infection in patients undergoing sacral nerve modulation (SNM) surgery. METHODS: We conducted a retrospective cohort analysis of 290 patients undergoing a total of 669 SNM procedures between 2002 and 2012 by 2 fellowship-trained female pelvic medicine and reconstructive surgery attending physicians at the University of California-Irvine Medical Center. Infection was defined as a charted abnormal examination finding at the implantation site (erythema, induration, purulent discharge) resulting in prescription of antibiotics, hospitalization, or explantation. We extracted information from the medical record regarding possible risk factors for infection including age, body mass index, immunosuppression (diabetes mellitus, chronic steroid use, smoker, chemotherapy), number of procedures per patient, and number of days between stages 1 and 2. In addition, we compared infection rates before and after 2008 when a clinical practice change was made with the implementation of home chlorhexidine washing (CHW) prior to SNM surgery. RESULTS: Thirty infections occurred, 25 of which were managed with oral antibiotics. Nine required intravenous antibiotics, and 11 required removal of the implanted device. Three patients experienced infection on 2 separate occasions. Seventeen infections had culture data available. Nine of the patients who underwent explantation had wound cultures positive for methicillin-resistant Staphylococcus aureus.Thirteen of the 26 patients who developed infection had medical histories significant for immunosuppression. Three patients developed late-onset abscess formation at 234, 257, and 687 days after stage 2, respectively. The median time between the most recent SNM procedure and development of infection was 14 days (range, 6-88 days).Body mass index and immunosuppression were significant predictors of infection, whereas age, parity, indication for procedure, and number of days between stages 1 and 2 were not found to be independent predictors. Three hundred twenty-three procedures were performed prior to and 346 procedures were performed after institution of home CHW. Twenty-four (80%) of the 30 reported infections were prior to CHW, whereas only 6 infections (20%) occurred after this change in practice. Prior to institution of CHW, the infection rate was 7.4%, and after institution of CHW, it was 1.7% (P = 0.002). Of the 83 patients with compliance data available for CHW use, 71 reported using CHW, whereas 12 reported not using CHW. CONCLUSIONS: Surgical site infection is a significant risk of SNM surgery, although our infection rate is lower than previously reported. Chlorhexidine washing appears to reduce the risk of infection in this population. Because the majority of infections requiring explantation were methicillin-resistant S. aureus positive, prophylactic treatment for this organism should be considered as an additional strategy to reduce infection. Body mass index and immunosuppression appear to be independent risk factors for infection.

Interstitial ectopic pregnancy: conservative surgical management.

INTRODUCTION: Interstitial pregnancy is a rare and life-threatening condition. Diagnosis and appropriate management are critical in preventing morbidity and death. CASE DESCRIPTION: Four cases of interstitial pregnancy are presented. Diagnostic laparoscopy followed by laparotomy and cornuostomy with removal of products of conception was performed in 1 case. Laparoscopic cornuostomy and removal of products of conception were performed in the subsequent 3 cases with some modifications of the technique. Subsequent successful reproductive outcomes are also presented. DISCUSSION: Progressively conservative surgical measures are being used to treat interstitial pregnancy successfully, with no negative impact on subsequent pregnancies.

The management of genitourinary fistula in the third millennium.

BACKGROUND: A vesicovaginal fistula (VVF) is an abnormal fistulous tract between the bladder and vagina, causing continuous loss of urine via the vagina. VVF is a relatively uncommon condition, but there is a drastically higher prevalence in the developing world. Furthermore, iatrogenic postoperative VVF is most common in developed countries, compared to mainly obstetric trauma in developing countries. In this review we focus on the development of current management techniques for VVF. METHODS: Medline was searched to identify articles related to urogenital fistulae, including VVF. Based on these reports we focus on the aetiology, clinical presentation, diagnosis and management of VVF. This in-depth review includes the optimal surgical timing, different surgical approaches (including minimally invasive techniques such as laparoscopic and robotic surgery), recommendations for postoperative care, surgical complications, and the need for further research in the use of robotic surgery to treat this condition. RESULTS: In all, 60 articles were identified and included in this review; eight were related to the aetiology, 12 to diagnosis, and 40 to the management of VVF. A thorough evaluation of VVF is imperative for planning the repair. Although the surgeonís experience typically influences the surgical approach, special situations will dictate the best approach. CONCLUSION: The treatment of genitourinary fistulae with robotic assistance continues to develop, but further research is necessary to fully understand the use of this technology.

A trial placement of a prophylactic ureteral catheter during the excision of a huge pelvic mass with incidental cystotomy.

Ureteral injuries are one of the major complications following gynecologic surgeries. They are serious, troublesome, often associated with significant morbidity, and are one of the most common causes for legal action against gynecologic surgeons. The reported rates of injury depend on the vigilance of diagnosis, type of surgery and other risk factors. We present a case of a 48 year old obese Caucasian female with no significant past medical history who came in with back pain and progressive abdominal swelling for the past three months and was found to have a very large pelvic mass. After preoperative evaluation, including: medical history, physical exam, and imaging studies showing a heterogenous mass 24.6 x 33.0 x 43.1, we predicted that the risk of urinary tract injuries was very high. We used preoperative prophylactic bilateral ureteral catheters to prevent injury. A surgical oncologist was consulted and an exploratory laparotomy was performed with removal of the large multi-lobulated pelvic mass + total abdominal hysterectomy, bilateral salpingo-oophorectomy, and appendectomy all performed at the same time. Patient had an incidental cystotomy during the procedure, which was repaired intra-operatively. The ureters remained intact with no injuries. The importance of thorough preoperative identification, evaluation and anticipation of ureteral injuries will be discussed in detail.
