Pulmonary edema and hyponatremia during hysteroscopic resection of uterine fibroids: case report.

Hyponatremia and fluid overload--the so-called TURP Syndrome--is a rare but well-understood complication of endoscopic resection of the prostate caused by rapid absorption of irrigating fluids from venous sinuses opened during the surgery. A similar syndrome occurring during endoscopic resection of the uterine mucosa has been postulated but only rarely described. New equipment and surgical techniques have recently been developed that allow for more invasive and extensive hysteroscopic surgery, which will inevitably lead to an increased incidence of this complication. We report the occurrence of a case of acute pulmonary edema occurring intraoperatively during hysteroscopic surgery, complicated postoperatively by severe hyponatremia. Anatomic and physiological causes of this syndrome are discussed, and recommendations are offered for avoiding and treating this potentially lethal complication.

The management of uterine leiomyomas.

OBJECTIVE: The objective of this document is to serve as a guideline to the investigation and management of uterine leiomyomas. OPTIONS: The areas of clinical practice considered in formulating this guideline are assessment, medical treatments, conservative treatments of myolysis, selective artery occlusion, and surgical alternatives including myomectomy and hysterectomy. The risk-to-benefit ratio must be examined individually by the woman and her health-care provider. OUTCOMES: Implementation of this guideline should optimize the decision-making process of women and their health-care providers in proceeding with further investigation or therapy for uterine leiomyomas, having considered the disease process and available treatment options, and reviewed the risks and anticipated benefits. EVIDENCE: English-language articles from MEDLINE, PubMed, and the Cochrane Database were reviewed from 1992 to 2002, using the key words "leiomyoma," "fibroid," "uterine artery embolization," "uterine artery occlusion," "uterine leiomyosarcoma," and "myomectomy." The level of evidence has been determined using the criteria described by the Canadian Task Force on the Periodic Health Examination. BENEFITS, HARMS, AND COSTS: The majority of fibroids are asymptomatic and will not require intervention or further investigations. For the symptomatic fibroid, hysterectomy offers a definitive solution. However, it is not the preferred solution for women who wish to preserve their uterus. The predicted benefits of alternative therapies must be carefully weighed against the possible risks of these therapies. In the properly selected woman with symptomatic fibroids, the result from the selected treatment should be an improvement in the quality of life. The cost of the therapy to the health-care system and to women with fibroids must be interpreted in the context of the cost of untreated disease conditions and the cost of ongoing or repeat treatment modalities. RECOMMENDATIONS: 1. Medical management should be tailored to the needs of the woman presenting with uterine fibroids and geared to alleviating the symptoms. Cost and side effects of medical therapies may limit their long-term use. (III-C) 2. In women who do not wish to preserve fertility and who have been counselled regarding the alternatives and risks, hysterectomy may be offered as the definitive treatment for symptomatic uterine fibroids and is associated with a high level of satisfaction. (II-A) 3. Myomectomy is an option for women who wish to preserve their uterus, but women should be counselled regarding the risk of requiring further intervention. (II-B) 4. Hysteroscopic myomectomy should be considered as first-line conservative surgical therapy for the management of symptomatic intracavitary fibroids. (I-B) 5. It is important to monitor ongoing fluid balance carefully during hysteroscopic removal of fibroids. (I-B) 6. Laparoscopic myolysis may present an alternative to myomectomy or hysterectomy for selected women with symptomatic intramural or subserous fibroids who wish to preserve their uterus but do not desire future fertility. (II-B) 7. Uterine artery occlusion may be offered as an alternative to selected women with symptomatic uterine fibroids who wish to preserve their uterus. (I-C) 8. Women choosing uterine artery occlusion for the treatment of fibroids should be counselled regarding possible risks, and that long-term data regarding efficacy, fecundity, pregnancy outcomes, and patient satisfaction are lacking. (III-C) 9. Removal of fibroids that distort the uterine cavity may be indicated in infertile women, where no other factors have been identified, and in women about to undergo in vitro fertilization treatment. (III-C) 10. Concern of possible complications related to fibroids in pregnancy is not an indication for myomectomy, except in women who have experienced a previous pregnancy with complications related to these fibroids. (III-C) 11. Women who have fibroids detected in pregnancy may require additional fetal surveillance when the placenta is implanted over or in close proximity to hen the placenta is implanted over or in close proximity to a fibroid. (III-C) 12. In women who present with acute hemorrhage related to uterine fibroids, conservative management consisting of estrogens, hysteroscopy, or dilatation and curettage may be considered, but hysterectomy may become necessary in some cases. (III-C) 13. Hormone replacement therapy may cause myoma growth in postmenopausal women, but it does not appear to cause clinical symptoms. Postmenopausal bleeding and pain in women with fibroids should be investigated in the same way as in women without fibroids. (II-B) 14. There is currently no evidence to substantiate performing a hysterectomy for an asymptomatic leiomyoma for the sole purpose of alleviating the concern that it may be malignant. (III-C) VALIDATION: This guideline was reviewed and accepted by the Clinical Practice Gynaecology Committee, and by Executive and Council of the Society of Obstetricians and Gynaecologists of Canada. SPONSOR: The Society for Obstetricians and Gynaecologists of Canada.

Outcome of pregnancies in women with uterine leiomyomas identified by sonography in the first trimester.

PURPOSE: We assessed the outcome of pregnancies in women with uterine leiomyomas (fibroids) documented by sonography in the first trimester of pregnancy. METHODS: We collected cases of women who had undergone first-trimester sonography and had uterine fibroids and singleton pregnancies with documented fetal heartbeats. We compared pregnancy loss rates and modes of delivery in these cases to a maternal-age-matched and gestational-age-matched control group of women who had normal uteruses and first-trimester pregnancies with documented fetal heartbeats. Sonograms in patients with fibroids were reviewed to determine the number of fibroids, their sizes, and their locations. Within the group of patients with fibroids, the pregnancy loss rate was also compared based on the number of fibroids and fibroid size and location. RESULTS: Our study population consisted of 143 women with leiomyomas, and our control group comprised 715 patients with a normal uterus. Among patients with fibroids, 14.7% of pregnancies resulted from assisted conception; in the control group, 6.4% of pregnancies resulted from assisted conception. The rate of spontaneous pregnancy loss in women with fibroids was almost twice the rate in women with normal uteruses (14.0% versus 7.6%; p < 0.05), and the loss rate was higher in women with multiple fibroids than in women with a single leiomyoma (23.6% versus 8.0%, p < 0.05). The loss rate was not significantly associated with fibroid size or location. The rate of cesarean-section delivery was higher in patients with fibroids than in patients with normal uteruses (38% versus 28%, p < 0.05). CONCLUSIONS: Uterine fibroids are associated with an elevated risk of spontaneous pregnancy loss. The loss rate is higher in patients with multiple fibroids than with a single fibroid. The cesarean-section rate is also higher in patients with fibroids than in patients with a normal uterus.

[The percutaneous treatment of uterine fibromas by means of transcatheter arterial embolization].

INTRODUCTION: We report our preliminary experience with arterial embolization of uterine fibroids in seven women, focusing on the technical aspects of the procedure and the clinical and morphological results during the follow-up. MATERIAL AND METHODS: February to December 1999 seven women (mean age 47) underwent transcatheter arterial embolization of both uterine arteries as a permanent treatment for fibroids. We included in this study single or multiple, bleeding and/or large fibroids, symptomatic on compression, contraindicated for myomectomy because of high surgical or anesthesiologic risks or myomata in which myomectomy could probably be converted into hysterectomy. Fibroids enlarging the uterus to the size of 25 weeks' pregnancy or more, pedunculated myomata or small submucous fibroids--smaller than 5 cm--were excluded. Uterine arterial embolization was performed bilaterally, till a total blockage of flow, by injecting permanent embolization material: polyvinyl-alcohol (PVA) particles of increasing size from 150 to 500 mu and in varying amounts from 10 to 24 mL, depending on fibroid size and degree of vascularization. RESULTS: A technical success was achieved in all cases and no late complications were seen. At 6-month clinical follow-up all compressive symptoms had disappeared; regular menses had returned in 57% of patients, milder hyper-dysmenorrhea was present in 28% compared to pretreatment symptoms; only in one case (14%) was permanent amenorrhea observed. The 3-month and 6-month US follow-up studies showed an average 40.7% (range 10-50%) and 51% (range 25-83%) reduction in the fibroid size, respectively. All the small myomata (about 2 cm in size) were unidentifiable at 6-month US follow-up. In no cases did new fibroids appear. DISCUSSION: Surgery is the traditional treatment for symptomatic uterine fibroids (hysterectomy, myomectomy). More recently, hormone therapy and operative endoscopy (laparoscopy and hysteroscopy) have been introduced as alternatives, together with uterine embolization previously applied preoperatively in extensive bleeding neoplasms or to control post-partum hemorrhage. Transcatheter embolization of the uterine arteries feeding large fibroids is a minimally invasive technique which could be safely used as an alternative to surgery, and a valuable in the definitive treatment of symptomatic, large or multiple, intramural or submucosal fibroids. In agreement with literature findings, in the present series symptoms resolved completely in over 85% of cases after embolization, with an average reduction in fibroid size over 50% at 6-month follow-up in large fibroids, whereas smaller size myomata were no longer detectable at US and no new fibroids had formed. CONCLUSIONS: Our preliminary experience confirms that arterial embolization is a promising alternative to surgery in the definitive treatment of fibroids, thanks to its high efficacy and safety, also reducing patient hospitalization and costs.

Laparoscopic myomectomy.

OBJECTIVE: To investigate the indications, surgical techniques and complications of laparoscopic myomectomy. MATERIALS AND METHODS: A retrospective study was carried out in 74 patients with fibroids > 3 cm from March, 1995 until May, 2000 at PUMC Hospital. Indications for surgery were symptomatic fibroids (20 cases), mainly pain or urine frequency; progressively increasing fibroid size (7 cases); coexistent adnexal pathology(26 cases) and infertility(21 cases). RESULTS: The number of fibroids of each patient varied from 1 to 4 with single fibroid of 62 cases (83.7%). The fibroids were located in anterior wall (30 cases), posterior wall (23 cases) and fundus (21 cases). A total of 93 fibroids were removed from these patients including 16 intramural fibroids and 77 subserous fibroids. The size of dominant fibroids ranged from 3 approximately 8 cm (mean 4.8 cm). In 19 cases (25.6%), the uterine wall was sutured in one layer. Mean duration of operation was 73 minutes and mean blood loss was 82 ml. Longer operating time and more blood loss were observed in patients with fibroids > or = 4 cm than those with fibroids < 4 cm. The difference was statistically significant ( P < 0.05). Mean postoperative hospital stay was 3.2 days and overall complication rate was 1.4%. The average postoperative follow-up period was 22 months (1 approximately 62 months). All the patients with symptoms showed remission of their complaints at 2-month follow-up. Recurrence of fibroid occurred in 1 case 1 year after initial operation and second laparoscopic myomectomy was given to her successfully. Five patients became pregnant. The pregnancy was uneventful and proceeded to selective caesarean section at term pregnancy in 4 cases. One miscarriage occured at 8 weeks in the 5th case. No adhesions at myomectomy site were found in these 5 patients. CONCLUSIONS: Our study suggests the feasibility of laparoscopic myomectomy in selected patients, which leads to effectiveness, low complication rate and satisfactory remission of symptoms. Further study on recurrence and fertility must be continued.

Hysterosalpingography before and after myomectomy: clinical value and imaging findings.

OBJECTIVE: Myomectomy is being performed increasingly for the treatment of menorrhagia and infertility. The purpose of this study was to describe the findings at hysterosalpingography before and after myomectomy and to correlate the findings with the operative technique and observations at surgery. This study also examined the value of hysterosalpingography in planning surgery, as well as in detecting postoperative complications and residual fibroids. MATERIALS AND METHODS: The study group comprised 32 patients who were consecutively referred for hysterosalpingography after myomectomy. The indications for myomectomy were infertility in all cases, associated with menorrhagia in 20, pelvic pain in 15, and urinary frequency in eight. Eighteen of the 32 patients also had hysterosalpingography before surgery. The hysterosalpingographic findings were reviewed without knowledge of the clinical findings and then correlated with surgical and pathologic findings. RESULTS: Preoperative hysterosalpingograms showed enlargement and/or distortion of the uterine cavity in 13 of 14 patients who had submucous fibroids or mural fibroids with a submucous component (mural/submucous fibroid). Cornual asymmetry was seen in seven of 18 patients, the result of an adjacent fibroid deforming one bilaterally in another two. In all four patients, tubal patency was shown after myomectomy. Intracavitary filling defects consistent with submucous or mural/submucous fibroids were found in 12 of 18 patients. After myomectomy, these defects resolved in eight cases; in the remaining four, persistent filling defects suggested residual submucous enlargement of the uterine cavity in only two of 32 patients; in both, residual mural and/or submucous fibroids were shown on sonography after surgery. Major distortion of the cavity after surgery was found in four patients; it was caused by filling defects consistent with residual submucous fibroids in two and by major synechiae in two. Diverticula at the site of resection of submucous fibroids were found in six patients. Major synechiae were found in two patients, resulting in unilateral or bilateral tubal occlusion. CONCLUSION: Hysterosalpingography before myomectomy can assist the surgeon in planning the surgical approach by showing the presence, size, and location of submucous fibroids and concomitant tubal disease. Hysterosalpingography after myomectomy shows residual fibroids and complications of surgery, such as synechiae and diverticula, that may affect further treatment.

High cumulative incidence of uterine leiomyoma in black and white women: ultrasound evidence.

OBJECTIVE: Uterine leiomyoma, or fibroid tumors, are the leading indication for hysterectomy in the United States, but the proportion of women in whom fibroid tumors develop is not known. This study screened for fibroid tumors, independently of clinical symptoms, to estimate the age-specific proportion of black and white women in whom fibroid tumors develop. STUDY DESIGN: Randomly selected members of an urban health plan who were 35 to 49 years old participated (n = 1364 women). Medical records and self-report were used to assess fibroid status for those women who were no longer menstruating (most of whom had had hysterectomies). Premenopausal women were screened by ultrasonography. We estimated the age-specific cumulative incidence of fibroid tumors for black and white women. RESULTS: Thirty-five percent of premenopausal women had a previous diagnosis of fibroid tumors. Fifty-one percent of the premenopausal women who had no previous diagnosis had ultrasound evidence of fibroid tumors. The estimated cumulative incidence of tumors by age 50 was >80% for black women and nearly 70% for white women. The difference between the age-specific cumulative incidence curves for black and white women was highly significant (odds ratio, 2.9; 95% CI, 2.5-3.4; P <.001). CONCLUSION: The results of this study suggest that most black and white women in the United States develop uterine fibroid tumors before menopause and that uterine fibroid tumors develop in black women at earlier ages than in white women.

Relative overexpression of the parathyroid hormone-related protein gene in human leiomyomas.

Uterine leiomyomas or fibroids are common among women of reproductive age, but their biology is poorly understood. The PTH-related protein (PTHrP) has been identified in a number of sites throughout the reproductive tract. We, therefore, examined whether fibroids express PTHrP mRNA and compared their level of expression with that in normal myometrium. Total RNA prepared from fibroid tissue and corresponding normal myometrium from seven patients was examined by RNase protection analysis. In all cases, fibroid and myometrial tissue expressed PTHrP, and in six of seven cases, PTHrP expression was higher in fibroids than in normal myometrium. Cultured fibroid cells from four patients also expressed higher levels of PTHrP mRNA than corresponding cultured normal myometrial cells. Tissue extracts from eight patients and conditioned medium from cultured cells from nine patients were examined for PTHrP immunoreactivity using a two-site immunoradiometric assay. In tissue extracts and conditioned medium, the mean PTHrP concentration was significantly higher in fibroids than normal myometrium. Immunohistochemical staining of fibroid and myometrial tissue was positive for PTHrP. Finally, PTHrP-(1-34) induced a dose-dependent increase in cAMP in fibroid and myometrial cells in vitro. These findings suggest that PTHrP may have an autocrine/paracrine function in regulating myometrial physiology and may play a role in regulating fibroid growth or differentiation.

Epidemiology of myomas.

Fibroids are a prevalent disorder occurring in at least half of American reproductive-age women. In general, the incidence and size increases with age. Most women never attribute or report any symptoms from their fibroids, and because of this the actual contribution of disease to symptoms of pelvic pain,menstrual symptoms, and infertility is poorly understood. The presence of fibroids can lead to multiple and disabling difficulties. Fibroids may cause pain and menstrual bleeding to the point of anemia. Fibroids clearly reduce fertility,increase preterm labor and delivery, and markedly increase the risk for cesarean delivery. Because the incidence varies according to population of interest, fibroids may explain some health disparities in different populations. For example,African Americans have a relatively poor outcome with assisted reproductive techniques compared with whites. Controlling for fibroid disease may explain this disparity, at least in part. Fibroids represent a tremendous public health burden on women and economic cost on society. Strategies to prevent, limit growth, and treat nonsurgically are needed. Fundamental and significant questions remain about fibroid disease,such as whether different clinical disease phenotypes (multiple versus single leiomyomas) contribute equally to symptoms and possess an equal likelihood of disease progression. For epidemiologic assessment of disease, a scoring system is urgently needed. Well-designed, controlled, prospective studies are still needed to define the natural history and correlate the presence of disease with symptomatology in women.
