Health resource utilization and costs during the first 90 days following robot-assisted hysterectomy.

INTRODUCTION AND HYPOTHESIS: To compare health resource utilization, costs and readmission rates between robot-assisted and non-robot-assisted hysterectomy during the 90 days following surgery. METHODS: The study used 2008-2012 Truven Health MarketScan data. All patients admitted as inpatients with a CPT code for hysterectomy between January 2008 and September 2012 were identified and the first hysterectomy-related admission in each patient was included. Patients were categorized based on the route of their hysterectomy and the use of laparoscopy as: total abdominal hysterectomy, vaginal hysterectomy (VH), laparoscopy-assisted supracervical hysterectomy, laparoscopy-assisted vaginal hysterectomy' and total laparoscopic hysterectomy (TLH). Hospitalization costs, including hospital, physician, pharmacy and facility costs, were calculated for the index admissions and for the 90-day follow-up periods. Health resource utilization was determined in terms of inpatient readmissions, outpatient visits, and emergency room visits, RESULTS: There were 302,923 hysterectomies performed over 5 years for benign indications in the inpatient setting (55% abdominal, 17% vaginal, and 28% laparoscopic). Concurrent use of robot assistance steadily increased and was reported in 50% of TLH procedures in 2012. The rates of readmission overall were 4.9% for robot-assisted procedures and 4.3% for procedures without robot assistance (OR 0.89, CI 0.82-0.97). Readmission rates were lowest for VH (3.2%) and highest for TLH (5.6%). Following robot-assisted hysterectomy and VH, 8.3% and 4.6% of patients, respectively, had more than ten outpatient visits in the 90-day follow-up period. The average total cost for 90 days was $16,820 for robot-assisted hysterectomy and $13,031 for procedures without robot assistance. Of the additional costs for robot-assisted surgery, 25% were incurred in the 90-day follow-up period. CONCLUSIONS: The study using private insurance data found that robot-assisted hysterectomy was associated with higher health resource utilization and costs than other minimally invasive approaches. Given the high costs associated with robot-assisted hysterectomy, it is important to understand the specific indications for this approach and to identify the patients who may benefit.

Comparing anticholinergic persistence and adherence profiles in overactive bladder patients based on gender, obesity, and major anticholinergic agents.

AIMS: Overactive bladder (OAB) is highly prevalent particularly among obese patients and significantly impacts quality of life. Anticholinergics are the first-line treatment. The effect of obesity on medication compliance has not been studied. Our study evaluated gender- and obesity-specific adherence and persistence of anticholinergic medications in OAB. We also compared adherence and persistence on solifenacin to oxybutynin, tolterodine, and all anticholinergics combined. METHODS: Truven Marketscan Commercial Claims and Encounter database from 2005 to 2013 was used. OAB patients aged 18-65 continuously enrolled for ≥12 months pre- and post-index were identified. Adherence was assessed by medication possession ratio (MPR) and proportion of days covered (PDC). Persistence was defined as number of days from anticholinergic initiation to discontinuation, switch, or end of study. Statistical analyses were performed using SAS 9.3. RESULTS: Among 122 641 OAB patients, most common comorbidities were hypertension, depression, and diabetes; patients with these conditions were more compliant. Obese patients were 7% less likely to adhere and 6% more likely to become non-persistent on anticholinergics compared to non-obese. Males were 20% more likely to adhere to anticholinergics compared to females. Oxybutynin, solifenacin, and tolterodine were the most common anticholinergics. Solifenacin demonstrated higher adherence and persistence compared to all anticholinergics combined. The proportion of patients still on solifenacin at 1 year was 17.11%, compared to 12.64% for all anticholinergics combined. CONCLUSIONS: Men are more likely to be adherent to anticholinergics than women. Obese patients are less likely to be compliant to medications, possibly related to severity of symptoms. Solifenacin had the highest rates of patient compliance.

Comparative analysis of overall cost and rate of healthcare utilization among apical prolapse procedures.

INTRODUCTION AND HYPOTHESIS: The annual cost of prolapse surgeries is expected to grow at twice the rate of population growth. Understanding the economic impact of apical prolapse procedures, including sacrospinous fixation (SSF), abdominal sacrocolpopexy (ASC), and laparoscopic sacrocolpopexy (LSC), is crucial. We aimed to compare overall cost of SSF versus ASC and LSC, as well as health resource utilization, up to 90-day follow-up. METHODS: Truven Marketscan Commercial Claims and Encounter databases 2008-2012 were used to calculate index and 90-day follow-up costs for SSF, ASC, and LSC with/without hysterectomy. Rates of inpatient readmissions, outpatient visits, and emergency room (ER) visits were also calculated during the follow-up period. Statistical analyses were performed using SAS 9.3. RESULTS: There were 17,549 SSF, 6126 ASC, and 10,708 LSC procedures. Mean index cost was lower for SSF (US$10,993) than ASC ($12,763, p < 0.0001) and LSC ($13,647, p < 0.0001). Concurrent hysterectomy impacted costs. Follow-up costs were likewise lower for SSF ($13,916) than ASC ($15,716, p < 0.0001) and LSC ($16,838, p < 0.0001). Lower rates of readmission were reported in SSF (4.22%) than ASC (5.40%, p = 0.0001) and LSC (4.64%, p = 0.0411). The rate of at least one ER visit was also lower for SSF (10.9%) than for ASC (12.0%, p = 0.0170) and comparable with LSC (10.6%, p = 0.0302). CONCLUSIONS: Overall mean costs are significantly lower for SSF than ASC/LSC, as are those for health resource utilization. Besides lower morbidity rates being associated with vaginal procedures, our results demonstrate another reason to consider the increased use of SSF over sacrocolpopexies in apical prolapse surgery.

Etiology, pathophysiology and biomarkers of interstitial cystitis/painful bladder syndrome.

PURPOSE: Interstitial cystitis/painful bladder syndrome (IC/PBS) is a chronic pain syndrome and a chronic inflammatory condition prevalent in women that leads to urgency, sleep disruption, nocturia and pain in the pelvic area, to the detriment of the sufferer's quality of life. The aim of this review is to highlight the newest diagnostic strategies and potential therapeutic techniques. METHODS: A comprehensive literature review was performed on MEDLINE, PubMed, and Cochrane databases gathering all literature about "Interstitial cystitis" and "Painful Bladder Syndrome". Visual analogue scales, epidemiological strategies, pain questionnaires and similar techniques were not included in this literature survey. RESULTS: The etiology, exact diagnosis and epidemiology of IC/PBS are still not clearly understood. To date, its prevalence is estimated to be in the range of 45 per 100,000 women and 8 per 100,000 men, whereas joint prevalence in both sexes is 10.6 cases per 100,000. There are no "gold standards" in the diagnosis or detection of IC/PBS, therefore, several etiological theories were investigated, such as permeability, glycosaminoglycans, mast cell, infection and neuroendocrine theory to find new diagnostic strategies and potential biomarkers. CONCLUSION: Due to the fact that this disease is of an intricate nature, and that many of its symptoms overlap with other concomitant diseases, it could be suggested to classify the patients with emphasis on the phenotype, as well as their symptom clusters, to tailor the diagnostic and management choices according to the observed biomarkers.

Current practice patterns for management of vulvodynia in the United States.

PURPOSE: To evaluate the current practice patterns for the management of vulvodynia in the United States (US) and to estimate healthcare costs related to this condition. METHODS: Truven MarketScan Commercial Claims and Encounters databases for years 2009-2013 were utilized for analysis. The study cohort included women, 18 years or older, with a diagnosis of vulvodynia (ICD-9 625.70), who had been continuously enrolled for 360 days from the date of diagnosis. Measures included the most common prescriptions, primary procedures, associated diagnoses, as well as net healthcare costs. Statistical Analysis Software 9.3 was used for statistical analysis. RESULTS: Among 24,122 subjects with vulvodynia, 12,584 met enrollment criteria. Mean age was 41.0 ± 12.9 years. Vulvar biopsy (29.6%), urinalysis (27.8%), urine culture (27.5%) and wet mount for infectious agents (25.5%) were commonly performed primary procedures. The most common prescriptions were antidepressants (32.4%), followed by opiates (27.6%), antifungals (26.1%), and steroidal agents (22.7%). Vulvodynia was frequently associated with vulvovaginitis (32.0%), urinary tract infection (20.6%), and chronic fatigue (18.6%). The mean net cost per patient including pharmacy claims during the follow-up period was $9591.80 (SD $14,595.52; 95% CI $9333.45-$9850.13). CONCLUSIONS: Our findings confirm great variation in the current management of vulvodynia. The variety of treatment approaches is a reflection of the poor current understanding of the etiology and pathophysiology of vulvodynia. Further research is needed to determine which treatments are most effective in the management of each subtype of vulvodynia.

Mesh complications and failure rates after transvaginal mesh repair compared with abdominal or laparoscopic sacrocolpopexy and to native tissue repair in treating apical prolapse.

OBJECTIVE: Our objective was to quantitate the extent of complications and failure rate for apical prolapse repair with transvaginal mesh (TVM) use versus sacrocolpopexy over a minimum of 2 years of follow-up. METHODS: Truven CCAE and Medicare Supplemental databases 2008-2013 were used for analysis. Patients with apical prolapse repair via transvaginal mesh (TVMR), abdominal sacrocolpopexy (ASCP), laparoscopic sacrocolpopexy (LSCP), or native tissue repair (NTR) and continuously enrolled for years were in the study cohort. Surgical failures were identified by reoperation for any prolapse or subsequent use of pessary. SAS® 9.3 was used for analysis. RESULTS: Mesh removal/revision was reported highest in TVMR (5.1 %), followed by LSCP (1.7 %) and ASCP (1.2 %). In those with concomitant sling, combined rates for mesh/sling revision were high, at 9.0 % in TVMR + sling, 5.6 % in ASCP + sling, and 4.5 % LSCP + sling. Sling-alone cases reported a 3.5 % revision rate. Pelvic pain (16.4-22.7 %) and dyspareunia (5.6-7.5 %) were high in all three approaches for apical prolapse repairs. Reoperation for apical prolapse was more common for TVMR (2.9 %) compared with NTR (2.3 %) [odds ratio (OR) 1.27; confidence interval (CI) 1.1-1.47; p 0.002]. Both ASCP and LSCP were superior to NTR (ASCP 1.5 %, OR 0.63, CI 0.46-0.86; p 0.003) and LSCP 1.8 % (OR 0.79, CI 0.62-1.01; p 0.07). Overall prolapse recurrence, as indicated by any compartment surgery for prolapse and/or pessary use, was also noted highest in TVMR (5.9 % OR 1.23, CI 1.11-1.36; p <0.0001). Laparoscopic sacrocolpopexies were slightly superior at 4.0 % overall recurrence (OR 0.83, CI 0.7-0.98); p 0.03). Failure of incontinence surgery was higher when the initial procedure combined prolapse and sling surgery (1.97 %) versus sling alone (1.6 %). CONCLUSIONS: Reoperation for apical prolapse is more common with TVMR than with sacrocolpopexies and NTR. Incontinence procedures are more likely to fail when performed along with prolapse repair than when performed alone. When mesh is used for repair, mesh revision is highest with TVMR and lowest with ASCP.

An International Urogynecological Association (IUGA)/International Continence Society (ICS) joint report on the terminology for female pelvic organ prolapse (POP).

INTRODUCTION: The terminology for female pelvic floor prolapse (POP) should be defined and organized in a clinically-based consensus Report. METHODS: This Report combines the input of members of two International Organizations, the International Urogynecological Association (IUGA) and the International Continence Society (ICS), assisted at intervals by external referees. Appropriate core clinical categories and a sub-classification were developed to give a coding to definitions. An extensive process of fourteen rounds of internal and external review was involved to exhaustively examine each definition, with decision-making by collective opinion (consensus). RESULTS: A Terminology Report for female POP, encompassing over 230 separate definitions, has been developed. It is clinically-based with the most common diagnoses defined. Clarity and user-friendliness have been key aims to make it interpretable by practitioners and trainees in all the different specialty groups involved in female pelvic floor dysfunction and POP. Female-specific imaging (ultrasound, radiology and MRI) and conservative and surgical managements are major additions and appropriate figures have been included to supplement and clarify the text. Emerging concepts and measurements, in use in the literature and offering further research potential, but requiring further validation, have been included as an appendix. Interval (5-10 year) review is anticipated to keep the document updated and as widely acceptable as possible. CONCLUSION: A consensus-based Terminology Report for female POP has been produced to aid clinical practice and research.

Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome: a historical perspective.

Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome is a congenital defect of the Müllerian ducts characterized by uterovaginal agenesis and underdeveloped female genital organs. This paper is a tribute to the contributors of this condition - August Franz Joseph Karl Mayer, Karl Freiherr von Rokitansky, Hermann Küster and Georges André Hauser. In addition to their contributions, we have discussed findings and reports of similar defects from other important scientists (Hippocrates, Albucasis, etc.) dating as far back as 460B.C. We have also discussed the disease types and different classification systems including VCUAM and AFS/ASRM among others. Even with several surgical and non-surgical treatment options, there are still many questions that remain unanswered and very little is known about the etiology or genetic predisposition of this condition.

Prolonged postoperative venous thrombo-embolism prophylaxis is cost-effective in advanced ovarian cancer patients.

OBJECTIVE: The purpose of this study was to investigate the cost-effectiveness of prolonged prophylaxis with enoxaparin in high-risk surgical patients with ovarian cancer. In addition, we sought to quantify the impact of prolonged prophylaxis (PP) on the incidence of venous thromboembolism (VTE), its related complications, and overall patient survival. METHODS: A Markov decision analytic model was used to estimate the costs, resource allocation and outcomes associated with the prolonged use of enoxaparin, for a total of four weeks after surgery, in patients undergoing primary debulking surgery for stage IIIC ovarian cancer. We estimated incremental cost per quality-adjusted life-year (QALY) at one and five year intervals; the estimated reduction in VTE episodes, bleeding episodes, and survival at the five year interval for a simulated cohort of 10,000 women. RESULTS: The incremental cost effectiveness ratio (ICER) for prolonged prophylaxis (PP) was $5236/QALY and $-1462/QALY at one and five years respectively. For patients receiving PP, the model estimated a 12% reduction in the clinically evident VTE episodes and a higher five-year survival (31.61% vs. 29.96%; p<0.0001). Resource allocation analysis reveals that 95% of initial investment cost of prolonged enoxaparin is recovered within one year. CONCLUSIONS: In ovarian cancer patients undergoing open abdominal surgery, prolonged VTE prophylaxis not only improves patient outcomes, but is also a cost saving strategy when modeled over five years. A significant reduction in the episodes of VTE and a higher overall survival warrants consideration for the routine use of PP in this patient population.

Obstetric outcomes in pregnant women with diabetes versus hypertensive disorders versus both.

OBJECTIVE: To compare obstetrical outcomes in pregnant women with diabetes versus hypertensive disorders versus both. METHODS: One million patients in the New Jersey Database were analyzed. Of which 6.91% had hypertension, 4.79% had diabetes, and 0.91% had both. Information was derived from a perinatal linked data-set provided by the Maternal Child Health Epidemiology (MCH Epi) Program in the New Jersey Department of Health and Senior Services. Linking of electronic birth certificates, hospital discharge records for mother and newborn, and infant death certificates for all infants born in New Jersey between the years 1997 and 2005 created the data-set. RESULTS: Coexistence of hypertension and diabetes increased with advancing maternal age (OR 3.41; CI 3.12-3.72). Among ethnic groups, diabetes was more common in Asians (OR 2.92; CI 2.84-3.00), while hypertension was more common in Blacks (OR 1.49; CI 1.46-1.53). Blacks followed by Asians had a higher risk of being in the combined category. Induction of labor (OR 4.16; CI 3.96-4.38), shoulder dystocia (OR 2.56; CI 2.05-3.19), operative vaginal delivery (OR 3.92; CI 3.29-4.66), cesarean deliveries with no trial of labor (OR 2.54; CI 2.40-2.69) as well as with failed trial of labor (OR 4.09; CI 3.88-4.31) were more common in the combined group. Neonatal outcomes were poor in the combined category, with high rate of preterm deliveries, neonatal intensive care unit (NICU) admissions (OR 2.14; CI 2.01-2.28), neonatal seizures (OR 2.30; CI 1.31-4.04), low 5-min APGAR scores (OR 1.78; CI 1.57-2.01), and longer NICU stay (OR 2.30; CI 2.15-2.47). CONCLUSIONS: Coexistence of hypertension and diabetes was associated with worse obstetric and neonatal outcomes than either alone. This should be emphasized to mothers during prenatal counseling. Further research should focus on interventions to improve morbidity in the combined category.

Obstetrical Hysterectomy, cesarean delivery and abnormal placentation.

OBJECTIVE: To examine the incidence, risk factors, and complications associated with Obstetrical Hysterectomy at a single University Hospital. STUDY DESIGN: This was a retrospective study of all cases of Obstetrical Hysterectomy performed between January 1993 and December 2005 at Temple University Hospital, Philadelphia, Pennsylvania. The current procedural terminology (CPT) codes were used to identify patients, and chart review was used to collect demographics and indications. RESULTS: During the study years, 19 patients underwent Obsterical Hysterectomy. Of these, 14 (73.7%) had cesarean during their current delivery. Further, 9 (47.4%) of the 19 had previous cesarean deliveries (CDs), with 5 (56%) of the 9 having had two or more previous CDs. Only two women (10.5%) never had cesarean either in the current or previous pregnancy. Eighteen of the women had singleton pregnancies, while only one woman had a twin gestation. A total of 42.1% of the cases had abnormal placentation with 21% experiencing placenta accreta, 15.8% with placenta previa, and 5.3% with placental abruption. A variety of complications arose including fever (52.6%) and blood transfusion (84.2%). CONCLUSION: CD in the current pregnancy and history of CD were strong risk factors for Obstetrical Hysterectomy. There was also a high occurrence of Obstetrical Hysterectomy in patients who had abnormal placentation. This information should be used to counsel women regarding the increased risk of remote complications of CD while discussing the route of delivery.

Novasure as a mechanical endometrial preparation agent in large uteri.

OBJECTIVE: We evaluated Novasure ablation as a mechanical endometrial preparation agent before Roller Ball endometrial ablation in lieu of GnRH agonists in large uteri. METHODS: A retrospective chart review of 20 consecutive patients undergoing Novasure ablation for mechanical endometrial preparation before Roller Ball ablation (RBNovasure group) was conducted and the results compared to that of 23 consecutive patients who received GnRH agonist (Leuprolide acetate) as a medical endometrial preparation before Roller Ball ablation (RB-Lupron group). The postoperative follow-up time frame was divided into immediate (3 mo), intermediate (3 to 12 mo) and long-term (12 to 32 mo). Rates of amenorrhea, heavy bleeding, cramping, and failure (repeat ablation or hysterectomy for heavy bleeding or persistent pain) were compared between the 2 groups. RESULTS: The mean rates of amenorrhea for the patients not lost to follow-up at 3 mo, 3 to 12 mo, and 12 to 32 mo visits were 45.5%, 58.8%, and 44.4% for the RB-Lupron group, and 80%, 86.7%, and 100% for the RB-Novasure group (P = .02, P = .08, and P = .02). Failure rates were 4.8%, 6.2%, and 55.6% for the RB-Lupron group; and 0 (0/20), 12.5% (2/16) and 0 (0/8) for the RB-Novasure group (P = .51, P = .50, and P = .02). The RB-Novasure group had a significantly lower rate of heavy bleeding and cramping. 86.4%, 58.8%, and 33.3% patients reported satisfaction with their treatment in the RB-Lupron group and 100%, 87.5%, and 75% in RB-Novasure group (P = .13, P = .07, and P = .11). CONCLUSION: Novasure ablation, for mechanical endometrial preparation before Roller Ball ablation, appears to be a superior alternative to medical preparation with GnRH agonists in patients with large uteri.

Does obesity affect the vaginal hysterectomy outcomes?

OBJECTIVE: To evaluate the effects of obesity on the perioperative outcomes in women who underwent vaginal hysterectomy. STUDY DESIGN: In this retrospective cohort study of all women who underwent vaginal hysterectomy for benign disorders at Temple University from January 1997 to December 2002, perioperative indices were compared between 149 obese (BMI ≥ 30 kg/m(2)) and 175 non-obese women (BMI < 30 kg/m(2)). RESULTS: The groups were similar with respect to age, parity, uterine weight, race, surgical indication, and previous pelvic surgery. Among medical conditions, hypertension and diabetes were significantly more common in obese women. Conversion to laparotomy occurred at similar rates in both obese (3.3%) and non-obese (5.7%) women. There was no significant difference between the groups regarding the operative time, length of hospital stay, transfusion rate, perioperative hemoglobin change, and perioperative complications (p < 0.05). CONCLUSION: Obesity does not affect the perioperative outcomes and surgical complications of vaginal hysterectomy.

Risk of peripartum hysterectomy by mode of delivery and prior obstetric history: data from a population-based study.

PURPOSE: To provide an estimate of the incidence of peripartum hysterectomy in the state of New Jersey and calculate the effect of mode of delivery and prior obstetric history. METHODS: A perinatal-linked dataset provided by the Maternal Child Health Epidemiology Program in the New Jersey Department of Health was used to obtain information from birth certificates and hospital discharge records. Using multivariate logistic regression, various demographic and clinical factors were assessed for association with peripartum hysterectomy. RESULTS: A total of 1,004,116 births were identified between 1997 and 2005 and 853 peripartum hysterectomies were performed (0.85/1,000 deliveries). Parity increased the risk of hysterectomy with nulliparous women having approximately half the risk compared to multiparous women. Cesarean delivery with no previous c-section almost doubled the risk (OR 2.20, CI 1.80-26.69) while in the presence of a previous c-section the risk was almost four times higher (OR 4.51, CI 3.76-5.40). Operative vaginal delivery did not result in any increase in the risk. CONCLUSIONS: Mode of delivery and prior obstetric history are major risk factors for peripartum hysterectomy. Patients desiring cesarean delivery need to be counseled on the risk of this serious complication.

The effectiveness of periodontal disease treatment during pregnancy in reducing the risk of experiencing preterm birth and low birth weight: a meta-analysis.

BACKGROUND: Treating periodontal disease during pregnancy to improve outcomes is controversial, and the results of randomized controlled trials (RCTs) are conflicting. The authors performed meta-analysis of these RCTs to assess the overall effect of treating periodontal disease during pregnancy. TYPES OF STUDIES REVIEWED: The authors performed a meta-analysis of studies found by means of two database aggregators OvidSP (12 databases) and EBSCOhost (11 databases). They included RCTs in pregnant women with periodontal disease who were assigned to a treatment arm (scaling and root planing with polishing) or a control arm (no treatment or only prophylaxis). RESULTS: Ten RCTs met the inclusion criteria for preterm birth (PTB), and eight RCTs met the inclusion criteria for low birth weight (LBW). The odds ratio of PTB in the treatment group was 0.589 (95 percent confidence interval [CI] = 0.396-0.875) and of LBW was 0.717 (95 percent CI = 0.440-1.169). Level of bias was the only significant predictor (P < .001) in subgroup analysis. High-quality studies (studies with low bias), which included 71.2 percent of participants, yielded the pooled estimates of 1.082 (95 percent CI = 0.891-1.314) for PTB and 1.181 (95 percent CI = 0.960-1.452) for LBW. CLINICAL IMPLICATIONS: Pooled results from the highest-quality RCTs do not support the hypothesis of a reduction of PTB or LBW in women who are treated for periodontal disease during pregnancy.

BMI and uterine size: is there any relationship?

To evaluate the influence of BMI on the prevalence of fibroids and uterine weight. Uterine pathology specimens of all the women who underwent hysterectomy for benign indications from 1995 to 2002 were studied. Patient characteristics such as age, race, body mass index (BMI), and parity were collected by chart review. The data were statistically analyzed using a 1-way analysis of variance and regression analysis. Uterine weight and fibroids were the dependent variables and BMI, age, and parity were the independent variables. The correlation between BMI and the presence/number of fibroids and their size was also studied. Among the 873 patients who underwent hysterectomy for benign indications, 47.1% were obese and these women had the highest mean uterine weight of 349.53 g. Overall, BMI had a significant correlation with the uterine size (P<0.0001). For every 1-point increase in BMI, uterine weight increased by 7.56 g. BMI positively correlated with uterine size both in the women with fibroids (P=0.038) and in those without fibroids (P=0.016). After controlling for fibroids, every 1-point increase in BMI resulted in an increase of 4.56 g in uterine weight (P<0.0001). In addition, there was a significant correlation between BMI and the presence of fibroids (P<0.0001), but not with the size of fibroids (P=0.11). A significant correlation was found between BMI and uterine weight in all the women, independent of age and parity. For every 1-point increase in BMI, there was a 7.56 g increase in uterine weight. This association needs to be further assessed in healthy women without uterine pathology.

The effect of obesity on total abdominal hysterectomy.

OBJECTIVE: To compare perioperative outcomes of total abdominal hysterectomy (TAH) between obese and nonobese women. METHODS: The medical charts of all women who underwent TAH for benign gynecological conditions at Temple University Hospital between 1997 and 2002 were reviewed. We excluded those who had concomitant surgery except for adnexal removal. The rates of perioperative indices were compared between obese (body mass index [BMI] ≥ 30 kg/m²) and nonobese women; p < 0.05 was considered significant. RESULTS: Of 357 women, 172 (48.2%) were obese, and 185 (51.8%) were not. Among the baseline characteristics, only race was statistically different between the groups. There were more African American women among the obese women (82.5% vs. 70%, p < 0.05). Postoperative complications, including urinary tract injury, were not significantly increased in the obese group. On the contrary, nonobese women had a significantly higher incidence of ileus (13.5% vs. 6.4%, p < 0.05). Although operative time was significantly prolonged for obese women, obesity did not increase the length of hospitalization, transfusion rate, and perioperative hemoglobin change. All these results remained the same even after controlling for race. CONCLUSIONS: Contrary to the general opinion, obesity does not significantly affect the perioperative outcomes for TAH performed for benign gynecological causes.

Resident competency in obstetric anal sphincter laceration repair.

OBJECTIVE: To estimate objectively the proficiency of obstetrican-gynecologist (ob-gyn) residents in third-degree perineal tear repair. METHODS: A total of 40 ob-gyn residents from 13 residency programs demonstrated their technique of perineal laceration repair on a modified beef tongue model. Two faculty members with expertise in repairing obstetric anal sphincter injury evaluated the residents using a checklist. The checklist identified three key steps of the procedure, including 1) repair of the internal anal sphincter; 2) selection of proper suture material; and 3) repair of the external anal sphincter, further evaluated using three subcomponents. RESULTS: The overall pass rate was 42.5% (17/40). Many residents missed critical steps of the repair. Year of training (P=.763), parent residency program (P=.5), and prior experience (P=.48) had no significant effect on the pass rate. There was greater than 90% concordance between the evaluators (r=0.9, P<.001). Satisfaction with the modified beef tongue model was higher than with current training methods in their program (7.81 compared with 6.92 on a scale of 1-10, P=.001). CONCLUSION: Ob-gyn residents demonstrated substandard skill in repairing anal sphincter laceration. The low pass rate of 42.5% suggests lack of adequate training in repair. The model had a high resident satisfaction, and high interobserver correlation was noted using the checklist. Thus, identification and evaluation of key steps using a standardized checklist may lead to standardization of repair and ensures consistency and quality. LEVEL OF EVIDENCE: III.
