Deep pelvic endometriosis: accuracy of pelvic MRI completed by MR colonography.

PURPOSE: This study assessed the diagnostic accuracy of pelvic magnetic resonance (MR) imaging completed by MR colonography for the preoperative evaluation of deep pelvic endometriosis in patients undergoing laparoscopic surgery. MATERIALS AND METHODS: A total of 143 patients (mean age 34.3 ± 5.1 years) with a clinical suspicion of deep pelvic endometriosis were assessed by pelvic MR and MR colonography. All patients underwent laparoscopic surgery 3-10 weeks after the MR examination. The presence, location, number and extent of endometriotic lesions were evaluated. Data obtained with MR were compared with surgical findings. MR sensitivity, specificity, positive (PPV) and negative (NPV) predictive values and diagnostic accuracy values were calculated for each site by considering the laparoscopic and histological findings as the reference standard. RESULTS: Laparoscopy confirmed the presence of endometriosis in 119/143 patients (83%); in 76/119 (64%) deep pelvic endometriosis was diagnosed, whereas in the remaining 43/119 (36%), superficial peritoneal implants and endometriomas were found. In 32/119 (27%) patients, intestinal lesions were detected. MR had sensitivity, specificity, PPV, NPV and diagnostic accuracy values of 67-100%, 85-100%, 83-100%, 84-100% and 84-100%, respectively, in recognising lesions located in different pelvic sites. CONCLUSIONS: MR imaging combined with colonography is a highly accurate tool for characterising deep endometriotic lesions in patients scheduled for laparoscopic surgery. In particular, MR colonography has very high accuracy in detecting colorectal involvement.

Accuracy of transvaginal sonography and contrast-enhanced magnetic resonance-colonography for the presurgical staging of deep infiltrating endometriosis.

OBJECTIVE: To investigate the accuracy of transvaginal sonography (TVS) and contrast-enhanced magnetic resonance-colonography (CE-MR-C) for the presurgical assessment of deep infiltrating endometriosis (DIE). METHODS: Ninety women were enrolled prospectively for suspicion of DIE. All patients underwent TVS and CE-MR-C, with each operator blinded to the results of the other exam, before laparoscopy. The sites of DIE examined by both imaging techniques were: rectovaginal septum, pouch of Douglas, uterosacral ligaments, vesicouterine pouch, bowel, bladder and vagina. The presence of adhesions and the involvement of adnexa and of a previous abdominal scar, when there was clinical suspicion, were also evaluated. TVS and CE-MR-C findings were compared with laparoscopic and histological results. RESULTS: Endometriosis was confirmed by laparoscopy in 95.6% (86/90) of cases. In 82.2% (74/90) of patients there was DIE. The global accuracy for TVS in the detection of DIE was 89.2%, sensitivity was 81.1%, specificity was 94.2%, positive predictive value was 89.6%, negative predictive value was 89.0%, the positive likelihood ratio was 13.9 and the negative likelihood ratio was 0.2. For CE-MR-C, these values were 87.2%, 71.1%, 97.1%, 93.7%, 84.6%, 24.4 and 0.3, respectively. CE-MR-C allowed diagnosis of all cases of bowel involvement; the accuracy for infiltration and stenosis was 100%. The accuracy of TVS for rectosigmoid nodules was 91.1% and that for infiltration was 88.9%. CONCLUSIONS: Both TVS and CE-MR-C showed satisfactory results for the presurgical assessment of DIE. TVS appears to be a powerful, simple, feasible, cost-effective tool for preoperative staging of DIE. CE-MR-C is an 'X-ray free' technique, which could be reserved for cases with deep infiltrating rectosigmoid lesions and for the prediction of stenosis and involvement of the upper part of the colon and small intestine.

Surgical technique to avoid bladder flap formation during cesarean section.

Cesarean section (CS) is now the most common major surgical procedure performed on women worldwide. A CS can be performed by either suturing or not suturing of the visceral peritoneum. Creation of the bladder flap is an integral step of the standard cesarean section. The bladder flap is made by superficially incising and dissecting the peritoneal lining to separate the urinary bladder from the lower uterine segment. It's still debated whether the formation of bladder flap is advantageous or not. If the uterine incision is made slightly above the vesicouterine peritoneal fold, the loose connective tissue between the uterus and the urinary bladder allows spontaneous descent of the bladder. Evidence on the role of the bladder flap in cesarean section is very limited. At present, it remains to be established whether there is any advantage in dissecting the bladder from the lower uterine segment during cesarean section.

Cervical squamous intraepithelial lesions of low-grade in HIV-infected women: recurrence, persistence, and progression, in treated and untreated women.

BACKGROUND: Human immunodeficiency virus (HIV)-infected patients are more predisposed than HIV-negative women to develop squamous intraepithelial lesions (SIL) of the uterine cervix, and cervical dysplasia may be of higher grade in HIV-positive women than in HIV-negative subjects, with more extensive and multi-centric involvement of the lower genital tract by human papillomavirus (HPV)-associated lesions. Moreover, recurrence and progression rate of cervical intraepithelial neoplasia (CIN) is particularly higher in immunocompromised women. DESIGN: Retrospective case-control study of HIV-positive women and HIV-negative controls, all affected by low-grade SIL of the uterine cervix, treated by loop excision or followed-up without treatment. Correlation of progression and recurrence of SIL with HIV status and CD4+ count. PATIENTS: From September 1990 to October 1997, 75 HIV-positive low-grade-SIL patients, 47 treated and 28 followed-up without treatment, and 75 HIV-negative low-grade-SIL controls, 45 treated and 30 followed-up. RESULTS: Among treated patients, 17/47 (36.2%) HIV-positive and 5/45 (11.1%) controls had recurrence (P < 0.0101, O.R. = 4.53, 95% CI = 1.5-13.7), progression of untreated lesion was seen in 15/28 (53.6%) HIV-positive and 7/30 (23%) controls (P < 0.05, O.R. = 3.79, 95% CI = 1.23-11.69). The risk of recurrence or progression of low-grade SIL linked to HIV seropositivity is about 4-5 times higher in comparison with seronegative counterpart, matched for age, risk factors and lesion size. More significantly, considering the cut-off of 200 CD4+/mm(3) in HIV-positive women, 13/17 cases of recurrence (P < 0.05, O.R. = 4.88, 95% CI = 1.28-18.58) and 10/15 cases with progression (P < 0.05, O.R. = 6.67, 95% CI = 1.24-35.73) were immunocompromised (<200 CD4+/mm3), with a significant higher risk of recurrence or progression linked to immunodeficiency status. Considering time of progression or recurrence, during follow-up, Kaplan-Meier curves shows that HIV-positive status and immunodeficiency are correlated with more rapid evolution of cervical dysplasia and HPV-related lesions: comparison of recurrence in treated patients report P < 0.005 and progression in untreated P<0.05 (Mantel-Haenszel log-rank test). CONCLUSIONS: Immunological status seems to be a determinant factor in prognosis of cervical SIL, HIV-positive women affected by this lesion, even if low-grade, need more aggressive management than the immunocompetent counterpart. Strict cytologic and colposcopic screening is recommended and CD4+ count and HPV-DNA testing may be useful risk indicators. Excisional procedures are preferred, while ablative treatments or wait and see policy may expose to some risk this type of population with poor compliance to follow-up.

Diagnostic inadequacy of dilatation and curettage.

OBJECTIVE: To assess the diagnostic inadequacy of dilatation and curettage (D&C) by comparing histologic findings with this technique with those obtained after hysterectomy. DESIGN: Retrospective clinical study. SETTING: University-affiliated hospital. PATIENT(S): Three hundred ninety-seven patients with abnormal uterine bleeding who underwent D&C and, within 2 months, hysterectomy because of histologic findings or persistence of symptoms. MAIN OUTCOME MEASURE(S): Comparison of histologic findings on D&C with those obtained after hysterectomy. RESULT(S): In 248 of 397 patients (62.5%), D&C failed to detect intrauterine disorders subsequently found at hysterectomy; the sensitivity was 46%, the specificity was 100.0%, the positive predictive value was 100.0%, and the negative predictive value was 7.1%. CONCLUSION(S): Dilatation and curettage is an inadequate diagnostic and therapeutic tool for all uterine disorders; this technique missed 62.5% of major intrauterine disorders, and all endometrial disorders were still present in the removed uterus.

Diagnostic accuracy of hysteroscopy in endometrial hyperplasia.

OBJECTIVES: To determine the diagnostic accuracy of hysteroscopy in the diagnosis of endometrial hyperplasia in women with abnormal uterine bleeding. METHODS: From 1993 through 1995, 980 women referred to our institution for abnormal uterine bleeding underwent diagnostic hysteroscopy with eye direct biopsy of the endometrium in case of macroscopic abnormalities. Hysteroscopic features were compared with pathologic findings in order to detect the reliability of the endoscopic procedure. Statistical analysis was performed with the McNemar test. RESULTS: Positive predictive value of hysteroscopy in the diagnosis of endometrial hyperplasia accounted for 63%. In fact hysteroscopic diagnosis of endometrial hyperplasia was confirmed at pathologic examination in 81 out of 128 patients. Sensitivity and specificity of the endoscopic procedure accounted for 98% and 95%, respectively. Negative predictive value accounted for 99%, as only two cases of atypical hyperplasia were missed at hysteroscopy. Positive predictive value was higher in postmenopausal patients compared to women in the fertile age (72 vs. 58%). CONCLUSIONS: Overall, results appear encouraging, since no case of endometrial hyperplasia was missed by hysteroscopy. The high diagnostic accuracy, associated with a minimal trauma, renders hysteroscopy the ideal procedure for both diagnosis and follow-up of conservative management of endometrial hyperplasia.

Transvaginal sonography and hysteroscopy in postmenopausal uterine bleeding.

OBJECTIVE: To compare the diagnostic accuracy of transvaginal ultrasound and hysteroscopy in the detection of endometrial pathologies in women with postmenopausal bleeding not using hormonal replacement therapy (HRT). METHODS: Between January 1997 and April 1998, 106 postmenopausal women with uterine bleeding not using HRT underwent a diagnostic work-up including pelvic examination, transvaginal ultrasound, hysteroscopy and endometrial biopsy. Sonographic measurement of endometrial thickness and hysteroscopic findings were compared with histological results. The 'classification tree' method was used to identify cut-off values of sonographic endometrial thickness that could be indicative of a class of uterine pathology. Statistical analysis was performed with the McNemar test. RESULTS: No case of endometrial cancer was found with a cut-off point of 5 mm of endometrial thickness evaluated by ultrasound, whereas all patients with endometrial thickness > or = 15 mm at sonography had an endometrial carcinoma. In the group of patients with endometrial thickness between 6 and 14 mm, we found normal atrophic endometria, benign and malignant pathology. On the other hand, the McNemar test showed a very good correspondence between hysteroscopy and histology (sensitivity 97.5% and specificity 100%), confirming its usefulness in diagnosis of postmenopausal uterine bleeding. CONCLUSIONS: Transvaginal ultrasound has revealed some limitations, mainly in the group of patients with endometrial thickness between 6 and 14 mm. The absence of endometrial malignancy in women with endometrial thickness < or = 5 mm and the high possibility of cancer in those with endometrial thickness > or = 15 mm should be confirmed in larger series. Hysteroscopy proved to be a simple and safe outpatient procedure with a high diagnostic accuracy, and in our opinion it should be considered in all women with postmenopausal uterine bleeding.

Antimicrobial prophylaxis in laparoscopic gynecologic surgery: a prospective randomized study comparing amoxicillin-clavulanic acid with cefazolin.

Numerous studies have been published in recent years about antimicrobial prophylaxis in gynecologic surgery, but the optimal drug and schedule for the different surgical procedures is still a matter of debate. The aim of the present study was to compare two ultra-short term antimicrobial prophylaxis regimens (amoxicillin-clavulanic acid and cefazolin) in preventing infections following laparoscopic gynecologic operations. Three hundred sixty women hospitalized for a laparoscopic gynecologic surgery procedure were included in the study between January 1999, and December 2001. Patients were randomly allocated to receive amoxicillin-clavulanic acid (2.2 g) [Group A] or cefazolin (2 g) [Group B] as a single dose 30 minutes before surgery. Each patient was assessed daily until discharge to evidence febrile status and the presence of infections at the operative site, urinary tract and respiratory tract. In the amoxicillin-clavulanic acid (Group A) and cefazolin (Group B) groups, overall 164 and 172 patients, respectively, were evaluable for prophylactic efficacy at hospital discharge. Infectious complications were infrequent in both groups with febrile morbidity occurring in only one patient (0.6%) in the amoxicillin-clavulanic group. No sign of infections at the surgical site, urinary tract and respiratory tract was observed in either group. No death due to sepsis was recorded. It is concluded that ultra-short term prophylaxis with both amoxicillin-clavulanic acid and cefazolin is safe and effective in elective laparoscopic gynecologic surgery.

Surgical treatment of recurrent ovarian cancer: report of 21 cases and a review of the literature.

AIM: To evaluate the role of secondary cytoreductive surgery in patients with recurrent ovarian cancer. PATIENTS AND METHODS: A retrospective chart review was conducted on 21 patients submitted to secondary cytoreductive surgery for apparently isolated and resectable recurrence of ovarian cancer, after a disease-free interval of at least 12 months. RESULTS: Fifteen patients (71%) had complete surgical debulking with no macroscopic tumor at the completion of the surgical procedure. Eight patients (38%) required an intestinal resection but no colostomy was performed. Eleven complications were recorded in nine patients, but no operative death occurred. The median survival time for all patients after diagnosis of recurrent disease was 29 months (range 6-96 months). Survival time after diagnosis of recurrence was not significantly related either to known prognostic factors of ovarian cancer or to the length of the clinical remission time. The absence of residual disease after salvage surgery was the only factory associated with prolonged survival. CONCLUSION: Secondary cytoreductive surgery is a safe procedure which should be offered to recurrent ovarian cancer patients with apparently isolated and resectable disease, and without ascitis.

Immunological markers in HIV-infected pregnant and non-pregnant women.

OBJECTIVE: To assess the influence of pregnancy on the course of HIV infection by comparing the behaviour of total lymphocyte counts and lymphocyte subsets (CD4(+) and CD8(+) and their ratio) in a cohort of infected pregnant women. SETTING: Tertiary referral centre for high risk obstetrics and infectious diseases in pregnancy. PATIENTS AND METHODS: A prospective study was designed, HIV infected women being enrolled at the beginning of pregnancy and sampled each trimester and in the puerperium. As controls, a group of non-pregnant HIV-infected women, cross-matched for age, risk factors and stage of disease were included and similarly evaluated in the same period. RESULTS: All the parameters, when longitudinally evaluated, were stable during gestation. Compared with non-pregnant subjects, patients had higher CD4(+) counts at the beginning and increased values of total lymphocytes count and subsets during the puerperium. Antepartum and postpartum risk factors such as drug abuse, smoking, antiretroviral therapy, length of gestation, maternal complications and HIV status of the neonate were not influential on the total lymphocytes counts and subsets. DISCUSSION: According to this data, pregnancy per se seems to have a negligible influence over the course of HIV infection, at least as far as immune parameters are concerned.

Effects of anodal TDCS stimulation of left parietal cortex on visual spatial attention tasks in men and women across menstrual cycle.

Sex hormonal variations have been shown to affect functional cerebral asymmetries in cognitive domains, contributing to sex-related differences in functional cerebral organization. The aim of this study was to investigate spatial attention by means of a bisection line test and computer-supported attention task during the menstrual cycle in healthy women compared to men, in basal condition and under Transcranial Direct Current Stimulation (TDCS) of the left parietal cortex. Women were studied during the menses, follicular and luteal phases, ascertained by transvaginal ultrasounds. In basal conditions, women showed a clear deviation toward the right in the bisection line test during the menstrual phase, similarly to men. The midpoint recognition in the computer-supported attention task was not influenced by the menstrual cycle for women, while men showed a significant increase in errors toward the left side. The anodal activation of the left parietal cortex did not affect the line bisection task, while in men it reduced the total amount of errors in midpoint recognition observed in the computer supported attention task. The hand-use effect demonstrated by the bisection-line test could be influenced by estrogen fluctuations, while the right hemisphere prevalence in spatial attention appears to be gender-related and scarcely influenced by the menstrual cycle. The left parietal cortex seems to exert a scarce effect on hand-use effect, while its activation is able to revert sex related right hemisphere supremacy.

Prevention of adhesions in gynaecological endoscopy.

Adhesions resulting from gynaecological endoscopic procedures are a major clinical, social and economic concern, as they may result in pelvic pain, infertility, bowel obstruction and additional surgery to resolve such adhesion-related complications. Although the minimally invasive endoscopic approach has been shown to be less adhesiogenic than traditional surgery, at least with regard to selected procedures, it does not totally eliminate the problem. Consequently, many attempts have been made to further reduce adhesion formation and reformation following endoscopic procedures, and a wide variety of strategies, including surgical techniques, pharmacological agents and mechanical barriers have been advocated to address this issue. The present review clearly indicates that there is no single modality proven to be unequivocally effective in preventing post-operative adhesion formation either for laparoscopic or for hysteroscopic surgery. Furthermore, the available adhesion-reducing substances are rather expensive. Since excellent surgical technique alone seems insufficient, further research is needed on an adjunctive therapy for the prevention and/or reduction of adhesion formation following gynaecological endoscopic procedures.

Hormone replacement therapy on ovarian and uterine cancer risk and cancer survivors: how shall we do no harm?

This article will focus on the results of the Women's Health Initiative on the effects of hormone replacement therapy on coronary heart disease, stroke, venous thromboembolism, breast cancer, and colorectal cancer. Data from other relevant trials, including the most recent data on ovarian and uterine cancer risk and on gynecologic cancer patients, are also discussed to provide some guidelines on prescribing hormone replacement therapy in clinical practice, particularly in gynecologic cancer survivors.

New Era of Office Hysteroscopy

One of the major problems of early office hysteroscopy was patient discomfort and pain due to the diameter of the scope. We overcame this handicap by using a small-diameter hysteroscope. We also developed a new way to access the cervix, the vaginoscopic approach, that permits hysteroscopy to be performed without speculum, tenaculum, or local anesthesia. We also perform operative procedures with this hysteroscope, including polypectomy and septum resection, always without anesthesia in an office setting.
