How Predictable Is the Operative Time of Laparoscopic Surgery for Ovarian Endometrioma?

Endometriosis is a tricky albeit common disease whose management largely relies on laparoscopy. We have studied the operative times of laparoscopic endometrioma surgery in order to assess their predictability and possible predictors. One hundred forty-eight laparoscopies were included, with a median operative time of 70 minutes (mean 75.14; 95% CI: 70.03-80.24). Half of the cases had a duration within 15-20 minutes above or below the median (IQR: 55-93.75), but the whole dataset ranged from 20 to 180 minutes, and the standard deviation was relatively large (31.4). Surgical times were significantly related to technical (number and size of the cysts) and nontechnical factors (age, parity, dysmenorrhea, and family history). At multiple logistic regression, after adjusting for number and size of the cysts, surgical times below the first quartile were associated with older age (>30 years old: aOR: 3.590; 95% CI: 1.417-9.091) and parity (≥1 delivery: aOR: 3.409; 95% CI: 1.343-8.651). Longer times, above the third quartile, were instead predicted by a familial anamnesis of endometriosis (aOR: 3.639; 95% CI: 1.246-10.627). Our findings indicate highly variable surgical times, which are predicted by unexpected nontechnical factors. This is consistent with the complexity of endometriosis and its treatment. Productivity and efficiency in endometriosis surgery should focus on the quality of healthcare outcomes rather than on the time spent in the operating theatres.

Looking for celiac disease in Italian women with endometriosis: a case control study.

In the last years, a potential link between endometriosis and celiac disease has been hypothesized since these disorders share some similarities, specifically concerning a potential role of oxidative stress, inflammation, and immunological dysfunctions. We investigated the prevalence of celiac disease among Italian women with endometriosis with respect to general population. Consecutive women with a laparoscopic and histological confirmed diagnosis of endometriosis were enrolled; female nurses of our institution, without a known history of endometriosis, were enrolled as controls. IgA endomysial and tissue transglutaminase antibodies measurement and serum total IgA dosage were performed in both groups. An upper digestive endoscopy with an intestinal biopsy was performed in case of antibodies positivity. Presence of infertility, miscarriage, coexistence of other autoimmune diseases, and family history of autoimmune diseases was also investigated in all subjects. Celiac disease was diagnosed in 5 of 223 women with endometriosis and in 2 of 246 controls (2.2% versus 0.8%; P = 0.265). Patients with endometriosis showed a largely higher rate of infertility compared to control group (27.4% versus 2.4%; P < 0.001). Our results confirm that also in Italian population an increased prevalence of celiac disease among patients with endometriosis is found, although this trend does not reach the statistical significance.

Regression of endothelial dysfunction in patients with endometriosis after surgical treatment: a 2-year follow-up study.

STUDY QUESTION: How does endothelial function change in women with endometriosis after surgical treatment? SUMMARY ANSWER: Surgical treatment of endometriosis leads to endothelial function improvement, resulting in reduction of cardiovascular risk. WHAT IS KNOWN ALREADY: Some recent studies have demonstrated that in young women with endometriosis, even if structural alterations are absent, endothelial dysfunction, expressed as flow-mediated dilation (FMD) impairment, can nevertheless occur. However, there are no data about changes of endothelial function in women with endometriosis after surgical treatment of endometriosis. STUDY DESIGN, SIZE, DURATION: This is a follow-up study carried out in 68 women enrolled in a previous study. Endothelial function was evaluated 2 years after surgical procedure and compared with baseline values. PARTICIPANTS/MATERIALS, SETTING, METHODS: Twenty-two patients who had undergone surgical treatment of endometriosis (named as patients with STE) and 10 control subjects without endometriosis, from the original study sample participated in this follow-up study. Assessment of endothelial function by FMD evaluation and measurements of serum markers of endothelial activation and inflammation were done in all these subjects. MAIN RESULTS AND THE ROLE OF CHANCE: After a 2-year follow-up period, FMD increased significantly with respect to baseline values among patients with STE [average pre- to post-difference: 5.07%, 95% confidence intervals (CI) 3.50, 6.63%; P < 0.001] but not among controls (average pre- to post-difference: 1.56%, 95% CI -0.55, 3.67%; P = 0.13). Follow-up FMD values were not significantly different between patients with STE and controls (average difference 1.50%, 95% CI -1.24, 4.23%; P = 0.27). Follow-up markers of inflammation and endothelial cells activation were similar among patients with STE and controls. LIMITATIONS, REASONS FOR CAUTION: Although this study represents the first in the literature assessing endothelial function after surgical treatment of endometriosis, further longitudinal studies are desirable to define better the real risk that women with a history of endometriosis will develop cardiovascular events. WIDER IMPLICATIONS OF THE FINDINGS: Endothelial dysfunction may be a better predictor of future cardiovascular events than traditional risk factors and the improvement in endothelial function we observed in patients after STE may have significant implications for their future cardiovascular risk. STUDY FUNDING/COMPETING INTEREST(S): No external funding has been either sought or obtained for this study. There are no conflicts of interest to declare.

Is a positive family history of endometriosis a risk factor for endometrioma recurrence after laparoscopic surgery?

A total of 148 patients were followed up for an average of 30.1 ± 17 months following to laparoscopic excision of ovarian endometriomas by a single surgical team. Bivariate and multivariate analyses were used to investigate the association between endometrioma recurrence and several factors, age, body mass index, family history, cyst diameter, number and location, adhesions or peritoneal implants, occurrence of spillage, postoperative treatment with gonadotropin-releasing hormone agonist, or pregnancies. The overall recurrence rate of the endometriomas was 18.2%. At bivariate analysis, recurrence rate was significantly higher in patients with a positive family history of endometriosis (40% vs 14.8%). Recurrence was also more frequent, albeit nonsignificantly, in patients with a history of dysmenorrhea, intraoperative spillage, and postoperative hormonal suppression. At multivariate analysis with logistic regression, a positive family history of endometriosis was the only variable independently associated with endometrioma recurrence following laparoscopic removal (odds ratio 3.245; 95% confidence interval: 1.090-9.661).

Endothelial dysfunction but not increased carotid intima-media thickness in young European women with endometriosis.

BACKGROUND: Atherosclerosis is a chronic and degenerative disease developing typically in the elderly; nonetheless, a condition of accelerated atherosclerosis can be observed precociously in the presence of some diseases. Endometriosis, a chronic benign gynecological disorder, shows some characteristics, such as oxidative stress, systemic inflammation and a pro-atherogenic lipid profile, which could increase the risk of developing accelerated atherosclerosis. The aim of our study was to evaluate markers of subclinical atherosclerosis in young European women with endometriosis. METHODS: This cross-sectional study included 37 women with endometriosis and 31 control subjects. The presence of subclinical atherosclerosis was investigated by ultrasound evaluation of common carotid intima-media thickness (ccIMT) and flow-mediated dilation (FMD); in addition, serum levels of lipids, inflammatory and coagulation parameters, as well as markers of endothelial inflammation and activation, were determined. RESULTS: Women with endometriosis showed significantly lower values of FMD compared with controls [mean difference: -4.62, 95% confidence interval (CI): -6.52, -2.73; P < 0.001], whereas no significant differences in ccIMT values were found between the two groups. As regards markers of endothelial inflammation and activation, women with endometriosis had significantly higher values of inter-cellular adhesion molecule 1 (P < 0.001), vascular cell adhesion molecule 1 (P < 0.001), E-selectin (P < 0.001), von Willebrand factor (P = 0.004) and ristocetin cofactor (P = 0.001) compared with controls. CONCLUSIONS: Our study suggests that women with endometriosis have more subclinical atherosclerosis, resulting in a higher risk of developing cardiovascular disorders. Moreover, our findings demonstrate that endothelial dysfunction can occur in the absence of structural atherosclerotic changes; its evaluation might be helpful in young women with endometriosis.

Infertility and adenomyosis.

Classically, the diagnosis of adenomyosis has only been possible on a hysterectomy specimen, usually in women in their late fourth and fifth decades, and, therefore, evaluating any relationship with infertility was simply not possible. As a consequence, to this day, no epidemiologic data exists linking adenomyosis to a state of subfertility. Today, new imaging techniques have enabled a noninvasive diagnosis at a much earlier time and a number of single-case or small series reports have appeared showing that medical, surgical, or combined treatment can restore fertility in women with adenomyosis, an indirect proof of an association. At the functional level, several anomalies found in the so-called junctional zone, or inner myometrium, in adenomyosis patients have been shown to be associated with poor reproductive performance, mainly through perturbed uterine peristalsis. Additional evidence for an association comes from experimental data: in baboons, adenomyosis is associated with lifelong primary infertility, as well as to endometriosis. Finally, indirect proof comes from studies of the eutopic and ectopic endometrium in women with adenomyosis proving the existence of an altered endometrial function and receptivity. In conclusion, sufficient indirect proof exists linking adenomyosis to infertility to warrant systematic clinical studies.

Adenomyosis and infertility.

Today an accurate diagnosis of adenomyosis can be made thanks to progress in imaging techniques: sonography and magnetic resonance imaging (MRI). This has made it possible to clinically correlate the presence of adenomyosis to infertility. At the same time, a series of pathogenetic hypotheses have been presented to explain this correlation. First, the identification of the myometrial junctional zone (JZ) and of its disruption and thickening has been linked to poor reproductive performance mainly through perturbed uterine peristalsis, a phenomenon that originates exclusively from the JZ in the nonpregnant uterus. In addition, a number of biochemical and functional alterations in both eutopic and heterotopic endometrium in women with adenomyosis have now been found to lead to lower receptivity, indicated by the presence of 'implantation marker' defects. In these patients there is also an altered decidualization and abnormal concentrations of intrauterine free radicals. All these abnormalities in the endometrial environment seem to contribute to subfertility. Several attempts have been made to restore fertility in adenomyosis patients, the oldest being gonadotrophin-releasing hormone agonists coupled to conservative surgery. Also, uterine artery embolization and MRI-assisted high-intensity focused ultrasound ablation have been tried with some degree of success.

A modified technique to reduce spillage and operative time: laparoscopic ovarian dermoid cyst enucleation 'in a bag'.

BACKGROUND: To describe the outcomes of a modified technique for conservative laparoscopic enucleation of ovarian dermoid cyst, placing the ovary in an endobag during enucleation to prevent intraperitoneal spillage. METHODS: Laparoscopic dermoid cyst enucleation was performed in 35 cases of premenopausal patients placing the ovary in an endobag at the beginning of the procedure and removing the cyst from the abdominal cavity by the same endobag. RESULTS: Dermoid cysts with a mean diameter of 6.3 ± 2.7 cm were enucleated and removed laparoscopically 'in a bag' without intra- or postoperative complications. Cyst rupture occurred in 10 cases (28.5%), but evident peritoneal contamination occurred in only 2 (5.7%; 95% confidence interval: 0.7-19.2%), because in 8 patients spillage was contained by the surrounding bag. The mean operative time was 64.6 ± 27 min. No signs or symptoms of peritonitis were observed. The mean postoperative hospitalization was 1.6 ± 1.4 days. Among the 12 infertile patients, 7 spontaneous pregnancies (58%) occurred. CONCLUSIONS: Laparoscopic conservative excision of dermoid cysts placing the ovary in an endobag at the beginning of surgery and removing the cyst by the same bag is a safe and effective approach to reduce intraperitoneal spillage and operative time.

Endometriosis, need for a multidisciplinary clinical setting: the internist's point of view.

Endometriosis is a common condition characterized by proliferation of endometrial tissue outside the uterus, both in the pelvis and in other extra-pelvic sites. The clinical picture of endometriosis is widely heterogeneous. A correct diagnostic work-up of these patients can sometimes be very difficult, since there are a number of gynecological, intestinal and systemic diseases mimicking endometriosis, as well as other conditions that could be associated with or are a consequence of this disorder. Therefore, multidisciplinary care should be encouraged to ensure correct evaluation and improve the management of these patients.

A case of metastatic struma ovarii treated with 131I therapy: focus on preservation of fertility and selected review of the literature.

Struma ovarii is a rare monodermal ovarian teratoma composed predominantly of mature thyroid tissue. We describe herein the case of a 22-year-old woman who underwent a right salpingo-oophorectomy for struma ovarii at the age of 12 years, who was admitted 8 years later with signs and symptoms of a left pelvic tumor. Laparoscopy detected a left ovarian endometriotic cyst and multiple nodules on the pelvic peritoneum, right lateral abdominal wall, diaphragm, vesical plica and liver. The diagnosis was abdominal and pelvic widespread dissemination of recurrent struma ovarii, with features consistent with the follicular variant of papillary thyroid carcinoma. The patient was treated with a combination of conservative surgery and two 131I administrations (cumulative activity of 350 mCi after dosimetric evaluation). Because of the high degree of hormonogenesis shown by the metastases, the first administration was performed following use of recombinant human (rh) thyroid-stimulating hormone (TSH) to reach adequate TSH levels. To avoid the 'stunning effect' and to obtain high-quality scintigraphy, a whole-body scan was performed with 123I after rh-TSH and before the 131I therapy. We also discuss the potential role and the possible benefit of using gonadotropin-releasing hormone analogs and ovarian tissue cryopreservation to preserve fertility in women treated with 131I for pelvic metastases from malignant struma ovarii.

Simultaneous ovarian and endometrial osseous metaplasia: a case report.

BACKGROUND: Endometrial ossification is a rare disease. More than 80% of cases occur after pregnancy, but it has been observed in patients with a history of endometritis, dilation and curettage, and metabolic disorders. CASE: A 42-year-old woman presented with osseous metaplasia of both the endometrium and ovaries. At laparoscopy both adnexa were covered with adhesions and were adherent to the posterior wall of the uterus. Following adhesiolysis, calcified nodules were removed from both ovaries with biopsy forceps. Endometrial bone tissue was removed by hysteroscopic resection. CONCLUSION: To our knowledge, this is the first reported case of osseous metaplasia of both the endometrium and ovaries since all cases described to date in the literature involved only the uterine cavity. Conservative management with endoscopic surgery is effective.

Short-term and long-term results of resectoscopic myomectomy with and without pretreatment with GnRH analogs in premenopausal women.

OBJECTIVE: The aim of this study was to analyze the safety and efficacy of resectoscopic myomectomy and to evaluate the influence of GnRH analog pretreatment on short- and long-term surgery outcome. METHODS: Data were collected from 80 consecutive resectoscopic myomectomies performed on premenopausal women. Forty-two patients (52.5%) had not received any preoperative medical treatment and in their case surgery was performed during the early proliferative phase (group A), whereas 38 patients (47.5%) had been treated with 2 months of intramuscular GnRH analog (triptorelin, Decapeptyl 3.75 mg) (group B). Myomas were classified according to the Wamsteker classification. The surgical time, recovery time, and complications were considered as short-term results. A 24-month follow-up was performed in order to assess long-term results, such as abnormal uterine bleeding recurrence, myomas recurrence, and need of repeat surgery. RESULTS: Patients' mean age was 38.8 +/- 5.39 years (range: 24-47) in group A and 38.97 +/- 7.46 years (range: 20-49) in group B. Forty-eight myomas were excised in group A (1.1 +/- 0.53 myoma per patient; mean diameter: 28.72 +/- 11.57 mm) and 42 in group B (1.09 +/- 0.29; mean diameter: 29.73 +/- 14.47 mm). Myoma type distribution was similar in both groups. Surgical time of the pretreated patients (group B) was significantly longer than that of untreated patients (group A 40 +/- 18.06 versus group B 57.65 +/- 29.61 min; P = 0.002). No significant difference was found between the two groups in the length of postoperative stay (group A 1.05 +/- 0.22 days versus group B 1.15 +/- 0.44). Only one complication occurred, represented by a uterine perforation. Histopathology revealed the presence of cellular myomas, without atypia, in three patients of each group. At follow-up, abnormal uterine bleeding occurred in 36.3% of group A patients and in 26.6% of group B patients, but the difference showed no statistical significance (P = 0.57). Five patients of myoma recurrence were observed, three in group A and two in group B. Only two patients, one from each group, required repeat hysteroscopic surgery. CONCLUSIONS: GnRH analog pretreatment, even if extremely beneficial in anemic patients, does not seem to improve short- and long-term outcome following resectoscopic myomectomy. Surgical time of pretreated patients is significantly longer, maybe because of difficulty in cervical dilatation, although further study is needed in order to confirm this hypothesis.

Reproductive outcome before and after laparoscopic or abdominal myomectomy for subserous or intramural myomas.

OBJECTIVES: To analyze the reproductive outcome before and after myomectomy in patients with subserous or intramural myomas, and to assess the factors influencing pregnancy rate after myomectomy. STUDY DESIGN: Out of 128 patients submitted to myomectomy, we considered eligible for this study only the 41 patients wishing to conceive after surgery and who did not present any plausible infertility factor, apart from the removed myomas. We have evaluated the pregnancy outcome prior to and following myomectomy, and analyzed the correlation between conception rate after surgery and patient's age at the time of the surgery, type of surgery, number and size of the myomas, location of the largest fibroid and previous pregnancies. RESULTS: Nineteen patients had been submitted to abdominal (group A) and 22 to laparoscopic myomectomy (group B). Prior to surgery, 28 pregnancies had occurred in 14 of the 41 patients, with a miscarriage rate of 57.1%. Following surgery 29 pregnancies occurred in 25 patients (60.9%), pregnancy rate being similar in both groups. The postoperative delivery rate was 86.2% whereas the miscarriage rate was reduced to 13.8% (P<0.001). Overall, 60% of deliveries were vaginal. No cases of ectopic pregnancy or uterine rupture occurred. Those patients who conceived after surgery were significantly younger (32.36+/-4.06 years versus 35.88+/-3.57 years; P=0.0073), and their removed myomas were significantly larger (5.80+/-2.69 cm versus 4.28+/-1.54 cm; P=0.0274). Furthermore, a multivariate analysis shows that, apart from age and diameter, the probability of conceiving after myomectomy is higher in case of intramural myomas (intramural versus subserosal: OR 12.382, 95% CI: 1.61-95.22) or laparoscopic surgery (laparoscopy versus laparotomy: OR 14.062, 95% CI: 1.40-141.15). CONCLUSIONS: Our results suggest that myomectomy significantly improves pregnancy outcome in patients with subserous or intramural fibroids, probably removing a plausible cause of altered uterine contractility or blood supply. The main determinants of pregnancy rate after surgery are patient age, diameter and intramural localization of the myomas and type of surgery.
