Hysterectomy rates in the United States, 2003.

OBJECTIVE: To estimate hysterectomy rates by type of hysterectomy and to compare age, length of stay, and regional variation in type of hysterectomy performed for benign indications. METHODS: We conducted a cross-sectional analysis of national discharge data using the 2003 Nationwide Inpatient Sample. These data represent a 20% stratified sample of U.S. hospitals. Women aged 16 years or older who underwent a hysterectomy were identified by International Classification of Diseases, 9th Revision, Clinical Modification procedure codes. We extracted data regarding age, race, diagnoses codes, length of stay, and hospital characteristics. Using 2000 National Census data and weighted data analysis for cluster sampling, we calculated hysterectomy rates. RESULTS: In 2003, 602,457 hysterectomies were performed, for a rate of 5.38 per 1,000 women-years. Of the 538,722 hysterectomies for benign disease (rate 4.81 per 1,000 women-years), the abdominal route was the most common (66.1%), followed by vaginal (21.8%) and laparoscopic (11.8%) routes. Mean ages (±standard deviation) differed among hysterectomy types (abdominal 44.5±0.1 years, vaginal 48.2±0.2 years, and laparoscopic 43.6±0.3 years, P<.001). Mean lengths of stay (±standard deviation) were also different (3.0±0.03 days, 2.0±0.03 days, 1.7±0.03 days, respectively, P<.001). The hysterectomy rate was highest in the South (5.92 per 1,000 women-years) and lowest in the Northeast (3.33 per 1,000 women-years). CONCLUSION: Despite a shorter length of stay, vaginal and laparoscopic hysterectomies remain far less common than abdominal hysterectomy for benign disease. LEVEL OF EVIDENCE: III

Incidence and characteristics of patients with vaginal cuff dehiscence after robotic procedures.

OBJECTIVE: To estimate the incidence and characteristics of patients with vaginal cuff dehiscence after robotic cuff closure. METHODS: We reviewed medical records from March 2004 to December 2008 of all patients with vaginal cuff dehiscence after a robotic simple and radical hysterectomy, trachelectomy, and upper vaginectomy using the robotic da Vinci Surgical System. RESULTS: Twenty-one of 510 patients were identified with vaginal cuff dehiscence (incidence 4.1%, 95% confidence interval 2.3–5.8%). In nine patients, the robotic procedure was performed for a gynecologic malignancy. Coitus was the triggering event in 10 patients. Patients most commonly presented with vaginal bleeding and sudden gush of watery vaginal discharge. Bowel evisceration was associated in six patients. Median time to presentation was 43 days or 6.1 weeks. Nineteen cases were repaired through a vaginal approach and one combined vaginal and laparoscopic. Three of 21 patients experienced a repeat dehiscence and required a second repair. CONCLUSION: Vaginal cuff dehiscence should be considered in patients with vaginal bleeding and sudden watery discharge after robotic cuff closure. The incidence is similar as previously reported for laparoscopic procedures. Contributing factors remain unknown but thermal effect and vaginal closure technique probably play major roles. LEVEL OF EVIDENCE: III

Cesarean delivery on maternal : Request maternal and neonatal outcomes

OBJECTIVE: To review systematically the evidence about maternal and infant outcomes of cesarean delivery on maternal request and planned vaginal delivery. DATA SOURCES: We searched MEDLINE, Cochrane Collaboration resources, and Embase and identified 1,406 articles through dual review using a priori inclusion criteria. METHODS OF STUDY SELECTION: We included English language studies published from 1990 to June 2005 that compared the key reference group (cesarean delivery on maternal request or proxies) and planned vaginal delivery. TABULATION, INTEGRATION, AND RESULTS: We identified 54 articles for maternal and infant outcomes. Virtually no studies exist on cesarean delivery on maternal request, so the knowledge base rests on indirect evidence from proxies with unique and significant limitations. Most studies compared outcomes by actual routes of delivery, resulting in variable relevance to planned routes of delivery. Primary cesarean delivery on maternal request and planned vaginal delivery likely differ with respect to individual outcomes; for instance, risks of urinary incontinence and maternal hemorrhage were lower with planned cesarean, whereas the risk of neonatal respiratory morbidity was higher and maternal length of stay was longer with planned cesarean delivery. However, our comprehensive assessment, across many outcomes, suggests no major differences between primary cesarean delivery on maternal request and planned vaginal delivery, but the evidence is too weak to conclude definitively that differences are completely absent. If a woman chooses to have a cesarean delivery in her first delivery, she is more likely to have subsequent deliveries by cesarean. With increasing numbers of cesarean delivery, risks occur with increasing frequency. CONCLUSION: The evidence is significantly limited by its minimal relevance to primary cesarean delivery on maternal request. Future research requires developing consensus about terminology, creating a minimum data set for cesarean delivery on maternal request, improving study design and statistical analyses, attending to major outcomes and their special measurement issues, assessing both short- and long-term outcomes with better measurement strategies, dealing better with confounders, and considering the value or utility of different outcomes.

Management of Bartholin duct cysts and abscesses: a systematic review.

Objective. To review systematically the literature, published in English, on recurrence and healing after treatment of Bartholin duct cysts and abscesses. Data Sources. We searched PubMed, EMBASE, CINAHL, LILACS, Web-of-science, the Cochrane database, and POPLINE from 1982 until May 2008. We searched the internet, hand-searched reference lists, and contacted experts and authors of relevant papers to detect all published and unpublished studies. Methods of Study Selection. We included any study with at least 10 participants, addressing either frequency of recurrence or healing time after treatment of Bartholin duct cyst or abscess. We followed MOOSE (meta-analysis of observational studies in epidemiology) guidelines. Of 532 articles identified, 24 studies (5 controlled trials, 2 cohort studies, and 17 case series) met all inclusion criteria. Study size ranged between 14 and 200 patients. Tabulation, Integration, and Results. The interventions included: (1) Silver nitrate gland ablation, (2) cyst or abscess fenestration, ablation, or excision using carbon dioxide (CO2) laser, (3) marsupialization, (4) needle aspiration with or without alcohol sclerotherapy, (5) fistulization using a Word catheter, Foley catheter, or Jacobi ring, (6) gland excision, and (7) incision and drainage followed by primary suture closure. The reported frequency of recurrence varied from 0% to 38%. There was no recurrence after marsupialization in available studies. Recurrence after other treatments varied, and was most common after aspiration alone. Healing generally occurred in 2 weeks or less. Conclusion. There are multiple treatments for Bartholin duct cysts and abscesses. A review of the literature failed to identify a best treatment approach. Target Audience: Obstetricians & Gynecologists, Family Physicians Learning Objectives: After completion of this article, the reader should be able to identify seven different treatments for Bartholin duct cysts or abscesses, contrast treatment choice complications and recurrence risks for the different options for treatment of Bartholin duct cysts or abscesses, and point out the limited quality and quantity of data upon which to choose best practices.

Reclosure of the disrupted laparotomy wound: a systematic review.

Objective: To review systematically all prospective, randomized trials published in English quantifying the success of reclosure of the disrupted laparotomy wound. Data Sources: The MEDLINE/PubMed, EMBASE, CINAHL, and Cochrane databases were searched from 1966 to 2004. References were hand-searched and their authors contacted to identify all published and unpublished eligible studies. Methods of Study Selection: We included all prospective, randomized trials measuring successful reclosure of disrupted laparotomy wounds in human subjects. Studies with fascial disruption, subfascial abscess, or ongoing contamination were excluded. Of over 2,098 potentially relevant articles, 8 were included, incorporating 348 patients. Tabulation, Integration, and Results: Two authors determined study inclusion. One investigator abstracted data, and a second checked for accuracy. The main outcome was successful healing after wound reclosure. Timing of reclosure, utility of antibiotics, and reclosure techniques were also analyzed. Successful healing after reclosure ranged between 81% and 100%. Failed healing included both superficial wound separation and reaccumulation of abscess. No serious morbidity or mortality was reported. Compared with healing by secondary intention, reclosure resulted in faster healing times (16–23 days versus 61–72 days), and in the one study that evaluated it, 6.4 fewer office visits. The optimal timing and technique for reclosure and the utility of antibiotics were inconclusive. Conclusion: Reclosure of disrupted laparotomy wounds was successful in over 80% of patients. Failed reclosure resulted in no life-threatening complications. Reclosure of disrupted laparotomy wounds is safe and decreases healing times.

Use of Anti-Skid Material and Patient-Positioning To Prevent Patient Shifting during Robotic-Assisted Gynecologic Procedures

STUDY OBJECTIVE To estimate patient shifting with the current practice of use of an antiskid material and patient positioning during robotic procedures in gynecology. DESIGN Pilot observational study (Canadian Task Force classification). SETTING Tertiary referral center. PATIENTS Twenty-two women undergoing robotic-assisted gynecologic procedures. INTERVENTION Antiskid material (egg-crate pink foam) was placed beneath patients and patient positioning was used during robotic-assisted procedures. MEASUREMENTS AND MAIN RESULTS Patient position was marked before and after surgery. Measurements of shift distance before and after surgery were determined for each patient. Median (range) shift distance was 1.3 (0-7.5) cm. There was no significant association between shift in position and either body mass index or duration of the Trendelenburg position. No shoulder neuropathic injuries were observed during the study. CONCLUSION Minimal patient shifting is observed with the use of an antiskid material and patient positioning described, without the use of shoulder braces and straps.

Leiomyoma-related hospitalization and surgery: prevalence and predicted growth based on population trends

OBJECTIVE To estimate leiomyoma-related inpatient care in the United States for 2007 with predictions for the ensuing 40 years. STUDY DESIGN We used the 2007 Nationwide Inpatient Sample to estimate hospitalizations and inpatient surgeries for uterine leiomyoma in US women 15 to 54 years. We used the US Census Bureau population projections to predict leiomyoma-related inpatient care through 2050. RESULTS In 2007, 355,135 women were hospitalized for leiomyoma (rate = 42 per 10,000 women-years). Black women had increased rates of hospitalization, hysterectomy, and myomectomy (relative risk, 3.5, 2.4, 6.8, respectively) compared with white women. Leiomyoma-related hospitalizations are predicted to increase 23% (to 437,874) between 2007 and 2050, with 20% and 31% increases in leiomyoma-related hysterectomies and myomectomies. CONCLUSION Leiomyoma-related inpatient care and major surgery remains substantial despite advances in less invasive treatment options. Given population growth, the projected burden of leiomyoma-related inpatient care will increase significantly by 2050, differentially impacting black vs white women.

Best practice smoking cessation intervention and resource needs of prenatal care providers.

OBJECTIVE: To describe smoking cessation interventions by prenatal care providers and to identify factors associated with best practice. METHODS: A mailed survey assessed implementation of the “5 As” of best practice (Ask about smoking; Advise patients to quit; Assess willingness to quit; Assist with a cessation plan; and Arrange follow-up), practice characteristics, intervention training, resources, barriers, and attitudes toward reimbursement. Each factor in association with provider type and best practice implementation was analyzed. RESULTS: Of 1,138 eligible North Carolina health professionals, 844 responded (74%); 549 were providing prenatal care and returned completed surveys. Most asked about smoking (98%) and advised cessation (100%). Across provider type, one third (31%) consistently implemented all “5 As” of best practice. Most providers (90%) had at least one material resource (eg, pamphlets), which correlated with nearly 10 times the adjusted odds of best practice (odds ratio [OR] 9.6, 95% confidence interval [CI] 1.3–72.9). Seventy percent had at least one counseling resource. Having a counseling resource (OR 2.5, 95% CI 1.4–4.4) and a written protocol to identify staff responsibilities (OR 2.5, 95% CI 1.5–4.3) were equally associated with best practice. More than one half of providers endorsed reimbursement as influential on best practice. CONCLUSION: Best practice is well-established to promote prenatal smoking cessation yet implemented by only one third of prenatal care providers in North Carolina. In this study, best practice was associated with resources, practice organization, and reimbursement. Augmented use of available resources (eg, toll-free hotlines) and adequate reimbursement may promote best practice implementation. LEVEL OF EVIDENCE: III

Complications in Robotic-Assisted Gynecologic Surgery According to Case Type: A 6-Year Retrospective Cohort Study Using Clavien-Dindo Classification

STUDY OBJECTIVE To estimate the risk of postoperative complications in robotic-assisted gynecologic surgery according to case type. STUDY DESIGN Retrospective cohort study (Canadian Task Force classification II-2). SETTING Mayo Clinic Arizona. PATIENTS All 1155 patients who underwent robotic-assisted gynecologic surgery between March 2004 and December 2009 were included. Patients were primarily white (94.3%), with a mean (SD) age of 51.5 (15.4) years, and were overweight, with body mass index (BMI) of 27.2 (6.8). INTERVENTIONS Risk of complications, overall and according to Clavien-Dindo grade, and incidence of specific complications were analyzed. Robotic-assisted gynecologic surgical procedures were categorized postoperatively according to case type as benign simple (e.g., oophorectomy, simple hysterectomy) in 552 (47.8%) patients, benign complex (e.g., excision of invasive endometriosis) in 262 (22.7%), urogynecologic in 121 (10.5%), and oncologic in 220 (19.1%). MEASUREMENTS AND MAIN RESULTS Intraoperative complications occurred in 3.2% of patients. Postoperative complications of any type occurred in 18.4% of patients. Conversion to laparotomy was necessary in 2.7%. Urologic complications were more common in urogynecologic cases (5.8%) as compared with benign simple (0.5%), benign complex (2.7%), and oncologic (3.2%). Bleeding complications were most common in oncologic cases (5%). Clavien-Dindo grade ≥ 3 complications occurred in 5.2% of patients overall, and were >3-fold likely to occur in benign complex, urogynecologic, and oncologic cases than in benign simple cases. When adjusted for age, BMI, estimated blood loss, operative time, length of stay, and previous pelvic surgery, complications were nearly twice as common for benign complex (odds ratio [OR] 1.7; 95% confidence interval [CI], 1.1-2.7), urogynecologic (OR 1.9; 95% CI, 1.0-3.4), and oncologic (OR 1.9; 95% CI, 1.1-3.1) cases as for benign simple cases, although weakly significant. Case type, BMI, estimated blood loss, and length of stay remained important factors in predicting postoperative complications. CONCLUSION The incidence of complications in robotic-assisted gynecologic surgery varies according to case type. Defining the role of patient and surgical variables such as case type in the occurrence of complications may help in identification of cases with increased risk, to improve patient counseling and surgical outcome.

Evaluation of Positioning Devices for Optimization of Outcomes in Laparoscopic and Robotic-Assisted Gynecologic Surgery

In this review, we evaluate techniques, devices, and equipment for patient positioning and their effect on patient outcomes, such as cephalad slide and neuropathy, in laparoscopic and robotic-assisted gynecologic surgery. We conducted a systematic review by searching MEDLINE, Embase, and Cochrane Library for relevant articles published over a 15-year period. Study selection, data extraction, and quality assessment were performed by 2 reviewers independently. Seven articles, including 3 randomized controlled trials and 4 case series, were included in our analysis. Four studies evaluated cephalad patient slide. In 2 randomized controlled trials (n = 103), the mean slide with various devices (i.e., memory foam, bean bag with shoulder braces, egg crate, and gel pad) ranged from 1.07 ± 1.93 cm to 4.5 ± 4.0 cm. The use of a bean bag with shoulder supports/braces was associated with minimal slide, with a median slide of 0 cm (range, 0-2 cm) in a retrospective series and with mean slide of 1.07 ± 1.93 cm in a randomized controlled trial (vs memory foam). No conclusive effect of body mass index on slide could be identified. Five studies evaluating the incidence of neuropathy found an overall incidence of 0.16% and no differences among slide-preventing devices. The minimal slide described across studies supports the conclusion that any of the currently used devices and techniques for safe patient positioning are within reason. The low overall incidence of neuropathy is also reassuring. Best evidence recommendations cannot be made for a specific device or technique; our findings suggest the importance of strict adherence to the basic tenets of safe patient positioning to minimize slide and prevent nerve injury.
