Gynecological endoscopy for symptomatic endometriosis.

The best available evidence on surgery for endometriosis-associated pain has been reviewed in order to define the benefit of various interventions in the most frequently encountered clinical conditions, and discuss the robustness of the reported data in light of the quality of the relevant study design. Methodological drawbacks limit the validity of observational, non-comparative studies on the effect of laparoscopy for stage I to IV disease. The results of three randomized, controlled trials, indicate that the absolute benefit increase of destruction of lesions compared with sham operation in terms of proportion of women reporting pain relief was between 30% and 40% after short follow-up periods. The effect size decreased with time and the reoperation rate, based on long-term follow-up studies, was as high as 50%. In most case series on excisional surgery for rectovaginal endometriosis, substantial short-term pain relief was experienced by about 70-80% of the subjects who continued the study. However, at one-year follow-up approximately 50% of the women needed medical treatments. Major complications were observed in 3-10% of the patients. Medium-term recurrence of lesions was observed in about 20% of the cases, and around 25% of the women underwent repetitive surgery. Routine complementary performance of denervating procedures cannot be recommended based on the quality of the available information, as only a few symptomatic patients complain of exclusively midline, hypogastric pain. Pain recurrence and reoperation rates after conservative surgery for symptomatic endometriosis are high and probably underestimated. Clinicians and patients should be aware that the expected benefit is operator-dependent and, especially in complex conditions, acceptable results can be assured in referral centers.

Meta-analysis using individual patient data from randomised trials to assess the effectiveness of laparoscopic uterosacral nerve ablation in the treatment of chronic pelvic pain: a proposed protocol.

BACKGROUND: Currently, there are a number of clinical trials, but no international collaboration for collating research on effectiveness of laparoscopic uterosacral nerve ablation (LUNA) for alleviating chronic pelvic pain. OBJECTIVE: Meta-analysis was used by collecting individual patient data (IPD) from the existing trials, to provide a comprehensive assessment of the effectiveness of LUNA that will be generalisable in various clinical contexts. METHODS: IPD will be sought and collected from all relevant (both already finished and continuing) randomised trials identified through previous systematic reviews. After obtaining raw data and cleaning the database, analysis will be of all patients ever randomised based on the intention-to-treat principle using endpoints measured at 12 months following randomisation. PROPOSAL: We will update searches, contact all authors, obtain data in whatever form it can be provided, build a single database, produce results for individual studies, have them verified by original authors, explore of any heterogeneity and reasons behind it and finally pool all raw data in to a meta-analysis using appropriate statistical methods. The project will test the effectiveness of LUNA for women with chronic pelvic pain. It will also motivate collaborating primary investigators to undertake new primary studies to corroborate or improve upon the conclusions derived from the retrospective analysis.

Extracorporeal circulation with low systemic heparinization during lung transplantation.

BACKGROUND: Some lung transplantation (LT) recipients suffer from pulmonary hypertension and right ventricular dysfunction or failure requiring extracorporeal circulation (ECC) to avoid catastrophic complications during surgery. The extracorporeal support usually requires systemic heparinization which is potentially associated with important side effects. We performed eight LT using preheparinized ECC circuits and an oxygenator associated with a lower level of systemic heparinization without evidence of perioperative complications. PATIENTS AND METHODS: From May 2002 to May 2005, 8 patients (5 men and 3 women) of mean age 22.5 +/- 9.5 years underwent bilateral sequential lung transplantation (BSLT) for cystic fibrosis (n = 6) or idiopathic pulmonary fibrosis (n = 2). All procedures were performed with ECC through a femoro-femoral veno-arterial bypass with preheparinized circuits and an oxygenator. RESULTS: No intraoperative mortality occurred. The mean ECC time was 147.8 +/- 31.3 minutes and the mean heparin administered was 3525 +/- 969.16 UI. No coagulopathy or thrombotic events were observed perioperatively. CONCLUSIONS: Our study confirmed the efficacy and safety of prehepanized circuits and oxygenator for femoro-femoral veno-arterial bypass during LT for patients with severe pulmonary hypertension requiring ECC.

Menstrual characteristics in women with and without endometriosis.

OBJECTIVE: To assess menstrual blood loss and other menstrual characteristics prospectively in women with and without endometriosis. METHODS: Three hundred fifteen premenopausal women undergoing laparoscopy for various reasons were asked to complete a pictorial blood loss assessment chart devised by Higham et al to evaluate menstrual flow on which the monthly score has been demonstrated to correlate directly with uterine blood loss measured by the alkaline hematin method. In addition, cycle length and flow duration were recorded. The women also were asked to grade dysmenorrhea severity using a 100-mm visual analogue and a 0-3-points verbal rating scale. RESULTS: One hundred sixty-three women had endometriosis, and 152 did not. The latter group comprised 59 women with a normal pelvis, 36 with nonendometriotic ovarian cysts, 29 with chronic pelvic inflammatory disease, and 28 with miscellaneous conditions. The median [interquartile range] pictorial blood loss assessment chart score was 110 [66.5-156.5] in women with endometriosis and 84 [56-129] in those without the disease (P = .007); 87 out of 163 (53%) women with endometriosis had a menstrual chart score equal to or greater than 100 compared with 56 out of 152 (37%) of those without (chi 2(1) = 8.02, P = .005; difference = 16%, 95% confidence interval, 6%, 28%). Menstrual flow duration was slightly longer in women with endometriosis (mean difference, 0.33 days). Dysmenorrhea visual analogue and verbal rating scores were significantly higher in the endometriosis than the nonendometriosis group. CONCLUSION: According to a visual chart, women with endometriosis had heavier menstrual flow and a significantly higher rate of abnormal menstrual scores that those without the disease.

Deep endometriosis conundrum: evidence in favor of a peritoneal origin.

OBJECTIVE: To determine whether the depth and volume of the pouch of Douglas differs in patients with endometriosis with and without deep lesions and to compare them with subjects with a healthy pelvis or with diseases other than endometriosis. DESIGN: Prospective, comparative study. SETTING: Tertiary care and referral center for patients with endometriosis. PATIENT(S): Women undergoing laparoscopy for infertility, pelvic pain, or adnexal anomalies (deep endometriotic rectovaginal lesions in 16 cases, endometriosis without deep lesions in 127 cases, miscellaneous anomalies in 35 cases, and normal pelvis in 26 cases). INTERVENTION(S): Douglas pouch depth measurement from the upper border of uterosacral ligaments to its base with a calibrated probe and volume assessment by a fluid-filling technique. MAIN OUTCOME MEASURE(S): Douglas pouch depth and volume. RESULT(S): Mean (+/-SD) Douglas pouch depth and volume measurements were 3.6 +/- 1.6 cm and 41.6 +/- 19.3 mL in women with deep endometriosis, 5.3 +/- 0.8 cm and 67.2 +/- 18.1 mL in those with peritoneal and ovarian lesions only, 5.2 +/- 0.9 cm and 67.6 +/- 12.6 mL in those with miscellaneous conditions, and 5.5 +/- 0.8 cm and 65.8 +/- 10.9 mL in those with normal pelvis. CONCLUSION(S): Reduced Douglas pouch depth and volume in women with deep endometriosis suggest that such lesions develop not in the rectovaginal septum but intraperitoneally and that burial by anterior rectal wall adhesions creates a false bottom, giving an erroneous impression of extraperitoneal origin.

A levonorgestrel-releasing intrauterine system for the treatment of dysmenorrhea associated with endometriosis: a pilot study.

OBJECTIVE: To evaluate the efficacy and safety of an intrauterine system releasing 20 microg of levonorgestrel per 24 hours in the long-term treatment of recurrent dysmenorrhea in women already operated on conservatively for endometriosis. DESIGN: A prospective noncomparative pilot study. SETTING: A tertiary care and referral academic center for patients with endometriosis. PATIENT(S): Twenty parous women with recurrent moderate or severe dysmenorrhea after conservative surgery for endometriosis who did not want further children. INTERVENTION(S): A levonorgestrel-releasing intrauterine system was inserted in each woman within 7 days of the start of a menstrual cycle. MAIN OUTCOME MEASURE(S): Variations in severity of dysmenorrhea during treatment according to a 100-mm visual analogue scale and a 0-3-point verbal rating scale, modification of a pictorial blood-loss assessment chart devised to evaluate the amount of menstrual flow, and degree of satisfaction after 12 months of therapy. RESULT(S): One woman was lost to follow-up after achieving amenorrhea and expressing satisfaction, and 1 requested system removal because of weight gain and abdominal bloating. In another subject, the levonorgestrel intrauterine system was expelled 3 months after insertion. The menstrual patterns in the remaining 17 women were characterized by amenorrhea in 4 cases, hypomenorrhea or spotting in 8, and normal flow in 5. Baseline and 12-month follow-up mean +/- SD blood loss scores were 111+/-36 and 27+/-26, respectively. At the same time, mean +/- SD visual analogue and verbal rating scale scores dropped, respectively, from 76+/-12 to 34+/-23 points and from 2.5+/-0.5 to 1.2+/-0.5 points. Four women were very satisfied with treatment, 11 were satisfied, 2 were uncertain, and 3 were dissatisfied at 12-month follow-up. CONCLUSION(S): Because of the amenorrhea or hypomenorrhea induced in most women, a levonorgestrel intrauterine system greatly reduced menstrual pain associated with endometriosis and achieved a high degree of patient satisfaction.

Hysterectomy for benign gynecologic disorders: when and why?

Controversy continues to swirl around hysterectomy-particularly about when and why it is appropriate for benign disorders. In the United States, one woman in three undergoes hysterectomy by age 65. The rate in the European Union nations ranges from 6% to 20%. In this review, the most recent epidemiologic data on hysterectomy are summarized, and the generally accepted indications for this procedure for benign gynecologic diseases are presented and discussed.

Individual patient data meta-analysis of randomized evidence to assess the effectiveness of laparoscopic uterosacral nerve ablation in chronic pelvic pain.

BACKGROUND: There have been conflicting results in randomized trials of the effects of laparoscopic uterosacral nerve ablation (LUNA) in chronic pelvic pain. Our objective was to perform a meta-analysis using individual patient data (IPD) to provide the most comprehensive and reliable assessment of the effectiveness of LUNA. METHODS: Electronic searches were conducted in the Medline, Embase, PsycInfo and Cochrane Library databases from database inception to August 2009. The reference lists of known relevant papers were searched for any further articles. Randomized trials comparing LUNA with no additional intervention were selected and authors contacted for IPD. Raw data were available from 862 women randomized into five trials. Pain scores were calibrated to a 10-point scale and were analysed using a multilevel model allowing for repeated measures. RESULTS: There was no significant difference between LUNA and No LUNA for the worst pain recorded over a 12 month time period (mean difference 0.25 points in favour of No LUNA on a 0-10 point scale, 95% confidence interval: -0.08 to 0.58; P = 0.1). CONCLUSIONS: LUNA does not result in improved chronic pelvic pain.

Association between endometriosis stage, lesion type, patient characteristics and severity of pelvic pain symptoms: a multivariate analysis of over 1000 patients.

BACKGROUND: The association between lesion type, disease stage and severity of pain was studied in a large group of women with endometriosis to verify whether endometrial implants at different sites determine specific complaints and to evaluate the validity of the current classification system in women with symptomatic disease. METHODS: A total of 1054 consecutive women with endometriosis undergoing first-line conservative or definitive surgery were included. Data on age at surgery, disease stage according to the revised American Fertility Society (AFS) classification, anatomical characteristics of endometriotic lesions, and type and severity of pain symptoms were collected and analysed by multiple logistic regression. RESULTS: Minimal endometriosis was present in 319 patients, mild in 139, moderate in 292 and severe in 304. A significant inverse relationship was demonstrated between age at surgery and moderate-to-severe dysmenorrhoea, dyspareunia and non-menstrual pain. A strong association was found between posterior cul-de-sac lesions and pain at intercourse [Wald chi (2) = 17.00, P = 0.0001; odds ratio (OR) = 2.64, 95% confidence interval (CI) = 1.68-4.24]. A correlation between endometriosis stage and severity of symptoms was observed only for dysmenorrhoea (Wald chi (2) = 5.14, P = 0.02) and non-menstrual pain (Wald chi (2) = 5.63, P = 0.018). However, the point estimates of ORs were very close to unity (respectively, 1.33, 95% CI = 1.04-1.71, and 1.01, 95% CI = 1.00-1.03). CONCLUSIONS: The association between endometriosis stage and severity of pelvic symptoms was marginal and inconsistent and could be demonstrated only with a major increase in study power.

Is cystic ovarian endometriosis an asymmetric disease?

OBJECTIVE: To investigate whether asymmetry exists in the left- and right-handed distribution of ovarian cystic lesions in a large series of women with endometriosis. DESIGN: Retrospective evaluation of a case series. SETTING: Tertiary care and referral academic centre for the study and treatment of endometriosis. POPULATION: A total of 1054 consecutive women undergoing first-line surgical treatment for endometriosis in an eight-year period. METHODS: Data were collected on indication for the intervention, age at surgery, parity and disease stage as well as side and size of ovarian endometriomas. MAIN OUTCOME MEASURE: Frequency of left- and right-sided ovarian endometriomas. RESULTS: Histologically confirmed endometriotic ovarian cysts were present in 561 women, which were on the left side in 255 instances, on the right in 148, and bilateral in 158. In the patients with unilateral endometriomas, the observed proportion of left cysts (255/403, 63%; 95% confidence interval, 58% to 68%) was significantly different from the expected proportion of 50%, (chi2(1), 28.41, P<0.001). Including also the bilateral endometriotic cysts gave a total of 413/719 (57%) left-sided and 306/719 right-sided endometriomas. The magnitude of these proportions did not vary appreciably during the eight years considered. The difference in proportion of left- and right-sided endometriotic cysts was virtually similar in subgroups of women with different indications for surgery. Cyst side was not related to age, parity or cyst diameter. CONCLUSIONS: The finding of a lateral asymmetry in the occurrence of ovarian endometriotic cysts is compatible with the anatomical differences of the left and right hemipelvis and supports the menstrual reflux theory.

Abdominal myomectomy for infertility: a comprehensive review.

To obtain estimates of the effect of abdominal myomectomy on infertility, information from studies published in the English language literature between 1982 and 1996 was retrieved. Articles were identified through hand and computerized searches using Medline. A total of 27 trials, all published in peer-reviewed journals, was identified, of which four were excluded from the analysis because of methodological limitations. All studies were non-comparative and only nine were prospective. The sample size was generally limited, the mean number of patients included being 49 and the mean number of infertile subjects 26. All patients were followed for at least 12 months after surgery in 12 studies. The combined estimate of pregnancy rates across prospective studies based on a total of 138 observed subjects was 57% [95% confidence interval (CI), 48-65%]. Time to conception varied from a mean of 8 to 20 months. Survival analysis was used in only three studies, with cumulative rates ranging from 57 to 67% at 1 year, and 63% at 5 years. The overall conception rate among seven prospective studies in which only women with otherwise unexplained infertility were recruited was 61% (95% CI, 51-70%) compared with 38% (95% CI, 20-59%) in two prospective studies that included patients with causes of infertility in addition to myomas (chi2(1) = 4.25, P = 0.04; mean difference = 23%, 95% CI, 1-43%; OR = 2.47, 95% CI, 1.03-5.94). The conception rate ranged from 58 to 65% in the three studies of women with only intramural and/or subserous fibroids and were respectively 53 and 70% in the two that considered only patients with submucous myomas. Data on recurrence after myomectomy were reported in 13 articles, with rates varying from 4 to 47%. According to the available evidence, slightly less than two-thirds of women with uterine leiomyomas and otherwise unexplained infertility conceived after myomectomy. However, comparison with expectant management is needed before drawing definitive conclusions on the effectiveness of this time-honoured conservative surgical procedure.

Metroplasty for the complete septate uterus: does cervical sparing matter?

STUDY OBJECTIVES: To verify if section of the cervical septum facilitates hysteroscopic metroplasty of a complete septate uterus, and to determine if this technique is associated with intraoperative bleeding or postoperative obstetric complications. DESIGN: Prospective, observational study. SETTING: Academic department and tertiary care referral center for malformations of the female genital tract. PATIENTS: Ten women with complete septate uterus. INTERVENTIONS: The cervical portion of the septum was incised with Metzenbaum scissors and the corporeal portion with microscissors under hysteroscopic guidance. MEASUREMENTS AND MAIN RESULTS: Mean +/- SD operating time for the entire procedure was 24 +/- 7 minutes, with a mean distention fluid deficit of 480 +/- 190 ml. No significant bleeding was encountered during cervical septum incision. At follow-up hysteroscopy, the cervices were competent, and no women experienced second-trimester abortion or premature delivery. CONCLUSIONS: Section of the cervical septum with scissors is simple, rapid, and safe, facilitates corporeal hysteroscopic metroplasty, and may be considered a valid procedure to correct a completely septate uterus.

Measurements of fetal limb bones in early pregnancy.

The fetal humerus, radius/ulna, femur, tibia/fibula and foot were measured in 296 pregnant women at 64-108 days' menstrual age, using vaginal sonography. All limb measurements correlated significantly with gestational age and biparietal diameter independently. Ratios of limb segment lengths did not change with gestation. Reference ranges (mean and 95% data intervals) were constructed for each limb segment. These data may prove useful in prenatal diagnosis of skeletal dysplasias and in the antenatal assessment of patients at risk of chromosomal abnormalities.
