Objective: To evaluate the rate of vaginal hysterectomy and outcomes after initiation of a prospective decision-tree algorithm to determine the optimal surgical route of hysterectomy., Methods: A prospective algorithm to determine optimal route of hysterectomy was developed, which uses the following factors: history of laparotomy, uterine size, and vaginal access. The algorithm was implemented at our institution from November 24, 2015, to December 31, 2017, for patients requiring hysterectomy for benign indications. Expected route of hysterectomy was assigned by the algorithm and was compared with the actual route performed to identify compliance compared with deviation. Surgical outcomes were analyzed., Results: Of 365 patients who met inclusion criteria, 202 (55.3%) were expected to have a total vaginal hysterectomy, 57 (15.6%) were expected to have an examination under anesthesia followed by total vaginal hysterectomy, 52 (14.2%) were expected to have an examination under anesthesia followed by robotic-assisted total laparoscopic hysterectomy, and 54 (14.8%) were expected to have an abdominal or robotic-laparoscopic route of hysterectomy. Forty-six procedures (12.6%) deviated from the algorithm to a more invasive route (44 robotic, two abdominal). Seven patients had total vaginal hysterectomy when robotic-assisted total laparoscopic hysterectomy or abdominal hysterectomy was expected by the algorithm. Overall, 71% of patients were expected to have a vaginal route of hysterectomy per the algorithm, of whom 81.5% had a total vaginal hysterectomy performed; more than 99% of the total vaginal hysterectomies attempted were successfully completed., Conclusion: Vaginal surgery is feasible, carries a low complication rate with excellent outcomes, and should have a place in gynecologic surgery. National use of this prospective algorithm may increase the rate of total vaginal hysterectomy and decrease health care costs.

Background: Increasing numbers of robotic hysterectomies (RH) are being performed. To provide ventilation (with pneumoperitoneum and steep Trendelenburg position) for these procedures, utilization of lung protective strategies with limiting airway pressures and tidal volumes is difficult. Little is known about the effects of intraoperative mechanical ventilation and high peak airway pressures on perioperative complications. We performed a retrospective review to determine whether patients undergoing RH had increased pulmonary complications compared to total abdominal hysterectomy (TAH)., Methods: We performed a single center retrospective review comparing the intraoperative, anesthetic, and immediate and 30-day postoperative course of patients undergoing RH to TAH, including intraoperative ventilatory parameters and respiratory complications. Patients undergoing TAH (201) from 2004 to 2006 were compared to RH (251) from 2009 to 2012. It was our hypothesis that patients undergoing RH would have increased incidence of postoperative pulmonary complications. A secondary hypothesis was that morbid obesity predicts pulmonary complications in patients undergoing RH. Complications were compared between groups using Fisher's exact test. To account for potential confounders, the primary analysis was performed for a subgroup of patients matched on the propensity for RH., Results: A total of 351 RH and 201 TAH procedures are included. Higher inspiratory pressures were required in ventilation of the RH group (median [25th, 75th] 31 [26, 36] cm H2O) than the TAH group (23 [19, 27] cm H2O) (P < .001) at 30 minutes after incision. Peak inspiratory pressures at 30 minutes after incision for RH increased according to increasing body mass index group (P < .001). There were 163 RH and 163 TAH procedures included in the propensity matched analysis. From this analysis, there were no significant differences in cardiopulmonary complications between RH and TAH (0.6% vs 1.2%; odds ratio = 2.0, 95% confidence interval = 0.2-2.4; P = 1.00). Surgical site infection was significantly lower in the RH compared to TAH group (0.6% vs 8.6%; P < .001). Hospital length of stay was longer for those who underwent TAH versus RH (median [25th, 75th] 2 [2, 3] vs 1 [0, 2] days; P < .001)., Conclusions: There was no significant difference in perioperative complications in obese and morbidly obese women compared to nonobese undergoing RH. Patients undergoing RH had shorter hospital stays, fewer infectious complications, and no increase in overall complications compared to TAH. Higher ventilatory airway pressures (RH versus TAH and obese versus nonobese) did not result in an increase in cardiopulmonary or overall complications. We believe that peritoneal insufflation attenuates the effect of high airway pressures by raising intrapleural pressure and reducing the gradient across terminal bronchioles and alveoli. Thus, we propose that lung protective strategies for patients undergoing RH account for the markedly elevated intraperitoneal and intrapleural pressures, whereas transpulmonary airway pressures remain static. This reduced transpulmonary gradient attenuates the strain on lung tissue that would otherwise be imposed by ventilation at high pressures.

Objective: To evaluate practice change after initiation of a robotic surgery program using a clinical algorithm to determine the optimal surgical approach to benign hysterectomy., Methods: A retrospective postrobot cohort of benign hysterectomies (2009-2013) was identified and the expected surgical route was determined from an algorithm using vaginal access and uterine size as decision tree branches. We excluded the laparoscopic hysterectomy route. A prerobot cohort (2004-2005) was used to evaluate a practice change after the addition of robotic technology (2007). Costs were estimated., Results: Cohorts were similar in regard to uterine size, vaginal parity, and prior laparotomy history. In the prerobot cohort (n=473), 320 hysterectomies (67.7%) were performed vaginally and 153 (32.3%) through laparotomy with 15.1% (46/305) performed abdominally when the algorithm specified vaginal hysterectomy. In the postrobot cohort (n=1,198), 672 hysterectomies (56.1%) were vaginal; 390 (32.6%) robot-assisted; and 136 (11.4%) abdominal. Of 743 procedures, 38 (5.1%) involved laparotomy and 154 (20.7%) involved robotic technique when a vaginal approach was expected. Robotic hysterectomies had longer operations (141 compared with 59 minutes, P<.001) and higher rates of surgical site infection (4.7% compared with 0.2%, P<.001) and urinary tract infection (8.1% compared with 4.1%, P=.05) but no difference in major complications (P=.27) or readmissions (P=.27) compared with vaginal hysterectomy. Algorithm conformance would have saved an estimated $800,000 in hospital costs over 5 years., Conclusion: When a decision tree algorithm indicated vaginal hysterectomy as the route of choice, vaginal hysterectomy was associated with shorter operative times, lower infection rate, and lower cost. Vaginal hysterectomy should be the route of choice when feasible.

Objective: Technological advances in surgical management of endometrial cancer (EC) may allow for novel risk modification in surgical site infection (SSI)., Methods: Perioperative variables were abstracted from EC cases surgically staged between January 1, 1999, and December 31, 2008. Primary outcome was SSI, as defined by American College of Surgeons National Surgical Quality Improvement Program. Counseling and global models were built to assess perioperative predictors of superficial incisional SSI and organ/space SSI. Thirty-day cost of SSI was calculated., Results: Among 1369 EC patients, 136 (9.9%) had SSI. In the counseling model, significant predictors of superficial incisional SSI were obesity, American Society of Anesthesiologists (ASA) score >2, preoperative anemia (hematocrit <36%), and laparotomy. In the global model, significant predictors of superficial incisional SSI were obesity, ASA score >2, smoking, laparotomy, and intraoperative transfusion. Counseling model predictors of organ/space SSI were older age, smoking, preoperative glucose >110 mg/dL, and prior methicillin-resistant Staphylococcus aureus (MRSA) infection. Global predictors of organ/space SSI were older age, smoking, vascular disease, prior MRSA infection, greater estimated blood loss, and lymphadenectomy or bowel resection. SSI resulted in a $5447 median increase in 30-day cost., Conclusions: Our findings are useful to individualize preoperative risk counseling. Hyperglycemia and smoking are modifiable, and minimally invasive surgical approaches should be the preferred surgical route because they decrease SSI events. Judicious use of lymphadenectomy may decrease SSI. Thirty-day postoperative costs are considerably increased when SSI occurs., (Copyright © 2013 Elsevier Inc. All rights reserved.)

Objective: To identify patient characteristics and perioperative factors predictive of 30-day morbidity and cost in patients with endometrial carcinoma., Methods: Data of consecutive patients treated with hysterectomy for endometrial carcinoma between 1999 and 2008 were collected prospectively. Thirty predictors were chosen from more than 130 collected based on anticipated clinical relevance and prevalence (more than 3%). Complications were graded per the Accordion Classification. Multivariable models were developed using stepwise and backward variable selection methods. Thirty-day cost analyses were expressed in 2010 Medicare dollars., Results: Of 1,369 patients, significant predictors (P<.01) of grade 2 and higher morbidity included American Society of Anesthesiologists physical status classification system class higher than 2 (odds ratio [OR] 2.1), preoperative white blood count (OR 2.1 per doubling), history of deep vein thrombosis (OR 2.1), pelvic and para-aortic lymphadenectomy (OR 2.3 compared with no lymphadenectomy), laparotomy (OR 2.8 compared with minimally invasive surgery), myometrial invasion more than 50% (OR 2.4), operating time (OR 1.9 per doubling), and grade 4 surgical complexity (OR 2.7 compared with grade 1). After controlling for patient factors in a multivariable model, laparotomy, pelvic, and para-aortic lymphadenectomy were associated with significant increases in cost compared with the use of minimally invasive surgery or hysterectomy alone., Conclusion: This analysis identifies patient and perioperative care factors predictive of 30-day morbidity and cost. These data are useful for preoperative counseling, for defining equitable reimbursement and factors critical for risk-adjustment when comparing outcomes, and for identifying areas for quality improvement in patients with endometrial carcinoma. Given the marked increases in morbidity and cost associated with laparotomy and lymphadenectomy, minimally invasive surgery and selective lymphadenectomy should be standard treatment for patients with endometrial carcinoma.

Eleven genes have been identified that increase the lifetime risk of developing ovarian cancer. The cumulative cancer risk of ovarian cancer varies with the mutation type and age. Ovarian cancer risk management options include surgical risk reduction with salpingo-oophorectomy and a newer step-wise approach with interval salpingectomy and delayed oophorectomy. Women should be counseled on the pros and cons of hysterectomy in the setting of reducing the risk of other cancers; eliminating the risk of endometrial cancer in Lynch Syndrome, potential risk of serous/serous-like endometrial cancer in BRCA1 carriers, and elimination of progestogen therapy that may increase breast cancer risk.

Objective We demonstrate the feasibility of detecting EC by combining minimally-invasive specimen collection techniques with sensitive molecular testing. Methods Prior to hysterectomy for EC or benign indications, women collected vaginal pool samples with intravaginal tampons and underwent endometrial brushing. Specimens underwent pyrosequencing for DNA methylation of genes reported to be hypermethylated in gynecologic cancers and recently identified markers discovered by profiling over 200 ECs. Methylation was evaluated individually across CpGs and averaged across genes. Differences between EC and benign endometrium (BE) were assessed using two-sample t-tests and area under the curve (AUC). Results Thirty-eight ECs and 28 BEs were included. We evaluated 97 CpGs within 12 genes, including previously reported markers (RASSF1, HSP2A, HOXA9, CDH13, HAAO, and GTF2A1) and those identified in discovery work (ASCL2, HTR1B, NPY, HS3ST2, MME, ADCYAP1, and additional CDH13 CpG sites). Mean methylation was higher in tampon specimens from EC v. BE for 9 of 12 genes (ADCYAP1, ASCL2, CDH13, HS3ST2, HTR1B, MME, HAAO, HOXA9, and RASSF1) (all p < 0.05). Among these genes, relative hypermethylation was observed in EC v. BE across CpGs. Endometrial brush and tampon results were similar. Within tampon specimens, AUC was highest for HTR1B (0.82), RASSF1 (0.75), and HOXA9 (0.74). This is the first report of HOXA9 hypermethylation in EC. Conclusion DNA hypermethylation in EC tissues can also be identified in vaginal pool DNA collected via intravaginal tampon. Identification of additional EC biomarkers and refined collection methods are needed to develop an early detection tool for EC. [ABSTRACT FROM AUTHOR]

Women afflicted by the hereditary breast and ovarian cancer syndrome face complex decisions regarding medical interventions aimed at reducing their risk of ovarian and breast cancer, interventions which in turn may interfere with their fertility and cause early menopause. This review addresses selected topics of importance and controversy in the management of the BRCA mutation carrier, such as psychological well-being and quality of life, breast and ovarian cancer screening, risk-reducing interventions for breast cancer and ovarian cancer, the issue of hysterectomy at the time of the risk-reducing salpingo-oophorectomy, health consequences of early surgical menopause, and safety of hormonal therapy after oophorectomy. The information presented is based on an extensive review of the literature on the selected topics and on the expertise of our multidisciplinary team. [ABSTRACT FROM AUTHOR]

Abstract: Objective: To determine the reliability of intraoperative frozen sections (IFSs) for surgical staging of endometrial cancer (EC). Methods: Data were collected prospectively on 784 consecutive patients with EC who were undergoing a hysterectomy at our institution from January 1, 2004, to December 31, 2008. The need for surgical staging was decided through IFS using 4 variables: tumor size, histologic grade, histologic subtype, and depth of myometrial invasion (MI). The IFS results were compared with the permanent paraffin sections (PSs) to assess for discordances. Results: In 30 of the 784 cases (4%), the PS pathology report was amended with discordant results. In addition, a definitive diagnosis of the 4 parameters was deferred to PS in 53 cases (7%), of which 30 (4%) were concordant and 23 (3%) were discordant. IFS-related deviations from the prescribed surgical algorithm occurred in 10 cases (1.3%; 95% confidence interval, 0.6%–2.3%). Of these 10 cases, 3 were amendments after PS review and 7 were IFS deferrals for definitive PS interpretation. Conclusions: Clinically significant discordance between IFS and PS occurred in only 1.3% of cases. Despite skepticism expressed in the medical literature, IFS provides highly reliable data to guide intraoperative treatment decisions at institutions with sufficient pathologic expertise.
