Effects of dexamethasone on quality of recovery following vaginal surgery: a randomized trial

OBJECTIVE Dexamethasone is a corticosteroid with minimal side effects that may improve quality of recovery. We sought to evaluate standard use of this medication prior to vaginal reconstructive surgery. STUDY DESIGN This was a double-blind, randomized, placebo-controlled trial of women undergoing vaginal reconstructive surgery for pelvic organ prolapse. Patients scheduled for an intraperitoneal vaginal vault suspension, with general anesthesia and an overnight stay, were enrolled. The intervention arm received dexamethasone 60 minutes prior to surgery, and controls received placebo. Postoperative pain medications, antiemetics, and voiding trials were standardized. Our primary outcome was the difference in Quality of Recovery (QoR-40) scores on postoperative day 1. Secondary measures included Postoperative Nausea and Vomiting Intensity scores, and visual analog scales for nausea/vomiting, and pain. Our power calculation demonstrated 31 subjects in each group would be necessary to document difference in QoR-40 scores; to allow for attrition, a goal of 74 subjects was set. RESULTS Seventy-four women were enrolled and randomized. Two withdrew, 9 were excluded, and 63 were analyzed (36 placebo, 27 dexamethasone). The mean age was 63 years. No significant differences were noted among demographics other than American Society for Anesthesiologists class; there were greater numbers of dexamethasone subjects that were class 3 (5 vs 11; P = .030). Postoperatively, more patients in the placebo group required promethazine as a rescue antiemetic for control of their nausea/vomiting (11 vs 2; P = .029). Placebo subjects also failed their voiding trials more frequently, which remained following a logistic regression controlling for suburethral sling (30 vs 15; P = .037). Regarding the QoR-40 following surgery, the emotional state domain declined less in dexamethasone patients (-14.3, interquartile range [IQR], 16.8 vs -4.6, IQR, 20.1; P = .042), indicating better symptoms. Whereas pain scales were similar, the visual analog scales for nausea/vomiting was lower in dexamethasone subjects (0.7; IQR, 4.1 vs 0.4; IQR, 1.4; P = .042). Postoperative Nausea and Vomiting Intensity scores were not significantly different; nevertheless, twice as many placebo subjects had severe range symptoms (4 vs 2; P = .47). No adverse effects from the dexamethasone were noted. CONCLUSION Use of dexamethasone prior to vaginal reconstructive surgery was associated with less nausea/vomiting and need for antiemetics as well as greater success with voiding trials. Furthermore, quality of recovery was enhanced, suggesting use of dexamethasone should be considered for these patients.

The Effect of Intravenous Acetaminophen on Postoperative Pain and Narcotic Consumption After Vaginal Reconstructive Surgery: A Double-Blind Randomized Placebo-Controlled Trial

Objective This study aimed to determine the effect of intravenous acetaminophen versus placebo on postoperative pain, satisfaction with pain control, and narcotic use after vaginal reconstructive surgery. Methods This was an institutional review board-approved, double-blind placebo-controlled randomized trial. Women scheduled for reconstructive surgery including vaginal hysterectomy and vaginal vault suspension were enrolled. Subjects received 1000 mg of intravenous acetaminophen or 100 mL placebo every 6 hours for 24 hours. Pain and satisfaction with pain control were assessed using visual analog scales and a numeric rating scale. Visual analog scales were collected at 18 and 24 hours postoperatively and at discharge. A sample size calculation determined 90 subjects would be required to detect a 30% reduction in postoperative narcotic use with 80% power and significance level of 0.05. Results One hundred subjects were enrolled. There were no differences in demographics or surgical data and no difference in narcotic consumption at multiple evaluation points. At 18 hours postoperative, median pain scores at rest were 27.0 (interquartile range, 35.0) for acetaminophen and 35.0 (interquartile range, 44.5) for placebo, finding no difference (P = 0.465). Furthermore, pain with activity and numeric rating scale-assessed pain scales were similar (P = 0.328; P = 0.597). Although satisfaction with pain control was high overall (91.5), no difference was noted. Conclusions Patients undergoing vaginal reconstructive surgery receiving perioperative intravenous acetaminophen did not experience a decrease in narcotic requirements or postoperative pain when compared with placebo. Reassuringly, pain scores were low and satisfaction with pain control was high for all subjects. The general use of this medication is not supported in these surgical patients.

Critical Anatomy Relative to the Sacral Suture: A Postoperative Imaging Study After Robotic Sacrocolpopexy.

Objective This study aimed to characterize pertinent anatomy relative to the sacral suture placed at time of robotic sacrocolpopexy using postoperative computed tomography and magnetic resonance imaging. Methods A vascular clip was placed at the base of the sacral suture at the time of robotic sacrocolpopexy. Six weeks postoperatively, subjects returned for a computed tomography scan and magnetic resonance imaging. Results Ten subjects completed the study. The middle sacral artery and vein coursed midline or to the left of midline in all the subjects. The left common iliac vein was an average of 26 mm from the sacral suture. To the right of the suture, the right common iliac artery was 18 mm away. Following the right common iliac artery to its bifurcation, the right internal iliac was on average 10 mm from the suture. The bifurcations of the inferior vena cava and the aorta were 33 mm and 54 mm further cephalad, respectively. The right ureter, on average, was 18 mm from the suture. The thickness of the anterior longitudinal ligament was 2 mm. The mean angle of descent of the sacrum was 70 degrees. Lastly, we found that 70% of the time, a vertebral body was directly below the suture; the disc was noted in 30%. Conclusions We describe critical anatomy surrounding the sacral suture placed during robotic sacrocolpopexy. Proximity of both vascular and urologic structures within 10 to 18 mm, as well as anterior ligament thickness of only 2 mm highlights the importance of adequate exposure, careful dissection, and surgeon expertise.

The Impact of Robotic-Assisted Surgery on Training Gynecology Residents.

Introduction To investigate the changes in surgical route of hysterectomy after implementation of robotics and to assess the impact on the surgical training of gynecology residents. Methods This was an institutional review board–approved retrospective analysis at 2 large academic community hospitals. Subjects undergoing hysterectomy during 2005 and 2011 were identified. A stratified random sample representative of the overall number of hysterectomies, 20 per month for each year, was obtained. Charts were reviewed for route of hysterectomy and resident involvement. Chi-square analysis was used for main outcomes. Results A total of 193 cases from 2005 and 146 cases from 2011 were included. A significant decline in vaginal hysterectomies was noted from 2005 to 2011: 62.2% (n = 120) to 27.4% (n = 40) (P < 0.001). Laparoscopic hysterectomies also declined from 30.1% to 19.9% during the same period (P < 0.026). In addition, although no robotic hysterectomies were performed in 2005, by 2011, this approach accounted for more than one fourth of all such surgeries. Of all cases examined, 40 in 2005 and 45 in 2011 were not attended by a resident. In 2005, 52% (21 of 40) of the uncovered cases were vaginal hysterectomies. However, in 2011, 55% (25 of 45) of the uncovered cases were robotic-assisted and only 11% (5 of 45) were vaginal hysterectomies. Conclusions The resultant decline in vaginal and laparoscopic hysterectomies coupled with an additional procedure to master places an increased burden on training programs. Although the impact of the changes on surgical competency is not yet known, our results identify potential areas for focus in training to ensure surgically competent physicians.

Impact of Pelvic Floor Physical Therapy on Quality of Life and Function After Obstetric Anal Sphincter Injury: A Randomized Controlled Trial.

Objectives There is no standard of care for women sustaining an obstetric anal sphincter injury (OASIS). We sought to determine whether pelvic floor physical therapy (PFPT) would improve the quality of life and function in women 12 weeks after OASIS. Methods This institutional review board–approved randomized trial enrolled primiparous women 2 weeks after delivery complicated by OASIS. After informed consent, all subjects underwent vaginal electromyography and anorectal manometry and completed validated questionnaires; measures were repeated for all subjects at 12 weeks after delivery. The intervention arm completed 4 PFPT sessions. The primary outcome was a change in the Fecal Incontinence Quality of Life. Results Three hundred four women were screened; 250 were excluded, and 54 were randomized. After four were lost to follow-up, analysis included 27 in the intervention arm and 23 in the control arm. Overall, mean age was 29.8 ± 4.7 years, and there were no demographic differences between groups. Fecal Incontinence Quality of Life domain scores showed improvement for both groups from baseline to 12 weeks for coping (P = 0.006) and depression (P = 0.009); however, there was no difference in domain scores between groups. For the secondary outcome of anorectal manometry, squeezing pressure improved for all subjects (P = 0.035) from baseline to 12 weeks. Vaginal EMG strength (microvolts) increased for all subjects in measures of rest average (P < 0.000), rapid peak (P = 0.006), and work average (P < 0.000), with no difference based on therapeutic arm. Conclusions All women showed improvements in quality of life and function at 12 weeks after delivery, regardless of treatment allocation. Further study is needed to determine whether PFPT provides a significant benefit to women having OASIS.

To Pack or Not to Pack? A Randomized Trial of Vaginal Packing After Vaginal Reconstructive Surgery.

Objective Placement of vaginal packing after pelvic reconstructive surgery is common; however, little evidence exists to support the practice. Furthermore, patients have reported discomfort from the packs. We describe pain and satisfaction in women treated with and without vaginal packing. Methods This institutional review board–approved randomized-controlled trial enrolled patients undergoing vaginal hysterectomy with prolapse repairs. The primary outcome was visual analog scales (VASs) for pain on postoperative day 1. Allocation to “packing” (“P”) or “no-packing” (“NP”) arms occurred intraoperatively at the end of surgery. Visual analog scales regarding pain and satisfaction were completed early on postoperative day 1 before packing removal. Visual analog scale scores for pain, satisfaction, and bother attributable to packing were recorded before discharge. All packing and perineal pads were weighed to calculate a “postoperative vaginal blood loss.” Perioperative data were collected from the hospital record. Our sample size estimation required 74 subjects. Results Ninety-three women were enrolled. After exclusions, 77 were randomized (P, 37; NP, 40). No differences were found in surgical information, hemoglobin levels, or narcotic use between groups. However, “postoperative vaginal blood loss” was greater in packed subjects (P < 0.001). Visual analog scale scores for pain before removal of packing (P, 41.6 vs NP, 46.3; P = 0.43] and before discharge (P, 35.0 vs NP, 40.0; P = 0.43] were not significantly different between treatment arms. Likewise, VAS scores for satisfaction before removal of packing (P, 81.0 vs NP, 90.0; P = 0.08] and before discharge (P, 90.0 vs NP, 90.5; P = 0.60] were not significantly different. Packed patients noted lower nursing verbal pain scores (P = 0.04) and used less ketorolac (P = 0.01). Bother from packing was low overall. Conclusions Although there was no difference based on VAS, women receiving vaginal packing had lower nursing documented pain and used less ketorolac than packed women. Vaginal packing may provide benefit and can remain part of the surgical practice.

Survey of male perceptions regarding the vulva

OBJECTIVE The purpose of this study was to characterize male preferences of vulvar appearance, their awareness of labiaplasty, and their knowledge of genital anatomy. STUDY DESIGN Men 18-80 years old were recruited via emails sent by an Internet provider to participate in a 27-question web-based survey. The questionnaire included images and queried demographics, mens familiarity with vulvar anatomy, preferences regarding labial appearance, and awareness of labiaplasty. Two deployments to >150,000 email addresses were sent. Demographic data were described using frequencies for categoric variables and mean measures of central tendency for continuous variables. Logistic regression models were used to analyze associations between demographics and responses. RESULTS Two thousand four hundred three men responded to the survey. After excluding incomplete and ineligible surveys, 1847 surveys were analyzed. The median age of respondents was 55 years. The majority was white (87%), married (68%), employed (69%), and had completed high school or beyond (97%). One-third of the respondents lived in the South, with the other regions nearly equally represented. A significant majority, 95%, reported having been sexually active with women, and 86% felt comfortable labeling the vulvar anatomy. With regard to preferences, more respondents considered smaller labia attractive compared to large labia; yet 36% of the men remained neutral. Men also showed a preference for partially or completely groomed genitals compared to natural hair pattern. Whereas 51% of participants believed the appearance of a womans labia influenced their desire to engage in sexual activity, 60% denied it affected sexual pleasure. Only 42% of men were familiar with labiaplasty, and 75% of all respondents would not encourage a female partner to change her genital appearance. Multivariable analysis revealed younger age to be associated with preferences for small labia and complete genital hair removal, as well as familiarity with labiaplasty. CONCLUSION In this national survey, men demonstrated familiarity with the female anatomy, but many did not feel it impacted sexual desire or pleasure. Moreover, the majority lacked strong preferences for a specific vulvar appearance and would not encourage a female partner to alter her genital appearance surgically.

Comparison of Perioperative Complications by Route of Hysterectomy Performed for Benign Conditions.

Objective The aim of this study was to compare perioperative complications by route of hysterectomy before and after the introduction of robotic surgery. Methods This is an ancillary analysis of a multicenter, retrospective cohort study with historical controls through the Fellows’ Pelvic Research Network. Hysterectomies performed for benign conditions were collected prior to introduction of the robot (prerobot) and the year after introduction of the robot (postrobot) at each institution. To obtain a representative annual case distribution for each institution, a maximum of 20 cases per month were selected using stratified random sampling. Patient demographics and intraoperative and postoperative complication data were collected. Results One thousand four hundred forty cases were included in this study, 732 in the prerobot and 708 in the postrobot period. Intraoperative complications in the prerobot group were highest in the abdominal group (7.4%) followed by vaginal (3.9%) and laparoscopic (3.7%) groups. Postoperative complications were higher in the vaginal (8.3%) and abdominal (7.4%) groups compared with laparoscopic (1.8%) groups (P = 0.03), because of a higher proportion of infections. In the postrobot period, intraoperative complications were lower in the vaginal (2.8%), robotic (3%), and laparoscopic (4.6%) groups compared with abdominal (10.8%) (P = 0.04). Postoperative complications were lowest in the vaginal (5.1%), laparoscopic (3.6%), and robotic (3%) approaches compared with the abdominal (13.9%) approach (P = 0.003). Conclusions Vaginal hysterectomy has comparable rates of perioperative complications when compared with robotic and laparoscopic approaches and should be considered as a primary surgical approach in the growing armamentarium of minimally invasive approaches for hysterectomy for benign conditions.

Histologic Anatomy of the Anterior Vagina and Urethra

Background Vaginal and urethral histology is important to understanding the pathophysiology of the pelvic floor. Methods En bloc removal of 4 female cadaveric pelvises was performed, with 18 to 25 serial sections obtained from each. The vaginal and urethral lengths were divided into distal and proximal sections; urethra was divided into anterior and posterior segments as well. Innervation and vasculature were qualified as small and large and quantified per high-power field. Results The mean vaginal length was 7.45 cm, and the mean urethral length was 3.38 cm. A distinct vaginal fibromuscular layer was noted, without evidence of a dense sheet of continuous collagen. An epithelial, lamina propria, and muscular layer surrounded the urethral lumen. Adipose and loose fibroconnective tissue separated the urethra from the anterior vagina in 41% of slides. Nerves and vasculature were concentrated in the lamina propria. More small nerves and vessels were grossly seen compared with larger counterparts in both the vagina and urethra. No significant differences in layer thickness, innervation, or vasculature were observed along the vaginal length. The posterior urethra had greater innervation than did the anterior (P = 0.012). The distal posterior urethra had more large vessels than did the proximal posterior urethra (P = 0.03). No other differences were noted in urethral sections. Conclusions A vaginal fibromuscular layer was confirmed, refuting a true fascia. Innervation and vasculature were quantitatively the same along the anterior vagina. However, the posterior urethra had greater innervation than did anterior and is most innervated proximally. Nerve and vascular histology may relate to pelvic floor disorder etiology.

Comparative Perioperative Pain and Recovery in Women Undergoing Vaginal Reconstruction Versus Robotic Sacrocolpopexy.

Background In this study of patients undergoing vaginal hysterectomy with either robotic or vaginal prolapse repair, there was no difference in quality of life in the weeks following surgery; however, less narcotics were used, less pain was documented by nurses and Surgical Pain Scale (SPS), and better performance on voiding trials was noted in those undergoing robotic sacrocolpopexy. Objectives Minimally invasive surgery for pelvic organ prolapse is the preferred surgical route for optimal recovery. However, information regarding patient-centered outcomes among various techniques is lacking. We sought to describe pain and quality of life in patients undergoing vaginal hysterectomy with uterosacral ligament suspension (USLS) compared with robotic-assisted sacrocolpopexy (RSC). Methods This institutional review board–approved prospective cohort study enrolled consecutive patients undergoing vaginal hysterectomy with USLS or with RSC. The primary outcome was pain on postoperative day 1 using the SPS. Nursing verbal pain scores, narcotic usage, surgical data, and Short-Form Health Survey 12 at baseline and 2 and 6 weeks after surgery were collected. A sample size calculation revealed 37 subjects per group would be required. Results Seventy-eight women were enrolled (USLS, n = 39; RSC, n = 39). There were no significant differences in scores on the SPS between groups. Subjects undergoing RSC had lower nursing verbal pain scores (P = 0.04), less narcotic consumption (P = 0.02), and lower estimated blood loss (P = 0.01) and were less likely to fail voiding trials (P < 0.001); however, surgery duration was longer (P < 0.001). After controlling for age, regression analysis revealed SPS “worst pain” was lower in the robotic arm (P = 0.01), but not in other scales of the SPS. At 2 and 6 weeks postoperatively, Short-Form Health Survey 12 scores were not different between cohorts. Conclusions Both USLS and RSC are minimally invasive, with similar quality-of-life scores after surgery. However, the robotic approach may be associated with less pain, less narcotic use, and better performance in voiding trials. Surgeons should consider these findings when counseling patients regarding treatment options.
