Laparoscopy versus laparotomy for the surgical management of apparent early stage ovarian cancer

OBJECTIVE

To compare the results of laparoscopic staging of apparent early ovarian cancer (EOC) with those obtained with comprehensive surgical staging via laparotomy.

METHODS

Consecutive patients undergoing comprehensive laparoscopic staging for presumed EOC (LPS group; N=15) were compared with historical controls selected from consecutive women who have had conventional staging with open surgery (LPT group; N=19).

RESULTS

No difference was found in demographics and preoperative variables between the two groups. There were no significant differences between the two groups with regard to median number of lymph nodes and likelihood of identifying metastatic disease. No conversion to laparotomy and no intraoperative complication occurred in the LPS group. Operative time was significantly longer in the LPS group when compared with the LPT group (377+/-47 vs. 272+/-81 min, P=0.002). One patient in the LPS group had a retroperitoneal haematoma recognized in the postoperative period, and this required laparotomy and ligature of the hypogastric arteries to achieve haemostasis. Minor postoperative complications occurred in 1 (6.7%) patient in the LPS group and in 8 (42.1%) patients in the LPT group (P=0.047). Hospital stay was significantly shorter in the LPS group [3 (2-12) vs. 7 (4-14) days, P=0.001]. Median (range) follow-up time was 16 (4-33) and 60 (32-108) months in the LPS and LPT group, respectively. Eleven (73.3%) patients in the LPS group and 13 (68.4%) in the LPT group received adjuvant treatment. There were no recurrences in the LPS group whereas 4 (7.1%) recurrences occurred in the LPT group. Overall survival was 100% in both groups.

CONCLUSION

Our results suggest that laparoscopic comprehensive surgical staging of EOC is as safe and adequate as the standard surgical staging performed via laparotomy.

Mammary ductoscopy for the evaluation of nipple discharge and comparison with standard diagnostic techniques

STUDY OBJECTIVE

To describe performance of breast duct endoscopy and compare the method with conventional diagnostic techniques.

DESIGN

Canadian Task Force classification III.

SETTING

Interdisciplinary Breast Unit of a university hospital.

PATIENTS

Consecutive and unselected series of 15 female patients including 20 breasts with nipple discharge.

INTERVENTIONS

Prospective data assessment on all patients with ductoscopy for nipple discharge between April 2003 to April 2004. All preoperative (mammography, ultrasonography, nipple smear) and minimally invasive (galactography, fine needle aspiration cytologic study) diagnostics were evaluated and compared with ductoscopy.

MEASUREMENTS AND MAIN RESULTS

Mammography on 20 breasts showed BI-RADS-I (5%), BI-RADS-II (50%), and BI-RADS-III (45%). Breast ultrasound scanning showed abnormalities, classified as BI-RADS-III equivalent lesions in all cases. Nipple smear showed in 69.2% a normal cytology and in most cases revealed a papilloma later (n=8/9). Unilateral galactography was performed in 46.7% who had spontaneous nipple discharge. Two galactography results were unremarkable, and open biopsy demonstrated 1 atypical ductal hyperplasia and papilloma. On 20 breasts of 15 women, 19 ductoscopies were successfully performed (95%). In 17 cases open biopsy followed ductoscopy, and 1 ductal carcinoma in situ (DCIS), 3 atypical ductal hyperplasia (ADH), 1 ductal hyperplasia without atypias, and 12 ductal papillomas were found.

CONCLUSION

Compared to nipple smear, the diagnostic value of ductoscopy in this study is superior but marginally inferior to galactography and highly specialized breast ultrasound scanning. Therefore ductoscopy needs to be evaluated on a larger scale, preferably in multicenter trials to further determine its potential and indications.

Laparoscopic findings, histopathologic evaluation, and clinical outcomes in women with chronic pelvic pain after hysterectomy and bilateral salpingo-oophorectomy

STUDY OBJECTIVE

To laparoscopically evaluate the pelvis of patients with chronic pelvic pain after hysterectomy and bilateral salpingo-oophorectomy, to determine any associated factors to the pain.

DESIGN

Retrospective cohort of patients with chronic pelvic pain after hysterectomy and bilateral salpingo-oophorectomy (Canadian Task Force Classification II-2).

SETTING

University-affiliated teaching hospital.

PATIENTS

From January 1990 through May 2002, 124 women with chronic pelvic pain after hysterectomy and bilateral salpingo-oophorectomy underwent laparoscopic and histopathologic evaluation of the pelvis.

INTERVENTION

Diagnostic laparoscopy was performed to inspect the pelvis for any signs of pathology. If any abnormalities were visualized, they were treated with CO2 laser resection and sent for histopathologic evaluation.

MAIN OUTCOME MEASURES

Laparoscopic and histopathologic findings of the pelvis, as well as subjective pain improvement after laparoscopy.

CONCLUSION

The most common histopathologic findings at laparoscopy in women with chronic pelvic pain after hysterectomy and bilateral salpingo-oophorectomy included adhesions, adnexal remnants, and endometriosis. Laparoscopic treatment of any pelvic pathologic condition improved pain symptoms in these women.

Interventions to reduce haemorrhage during myomectomy for fibroids

BACKGROUND

Uterine myomas (fibroids) are benign tumours of the uterus. Myomectomy, the surgical removal of the myomas, is an important treatment option especially for women who desire to preserve their uteri. The major problem with myomectomy is excessive bleeding from increased uterine blood supply, and this can be life-threatening and prolong postoperative stay. Knowledge of the effectiveness of the interventions used to reduce blood loss during myomectomy is essential to enable evidence-based clinical decisions.

OBJECTIVES

To assess the effectiveness and safety of interventions (other than GnRH analogues) to reduce blood loss during myomectomy.

SEARCH STRATEGY

Electronic searches were undertaken in the Cochrane Menstrual Disorders and Subfertility Group specialised register, CENTRAL (Cochrane Library Issue 1, 2006), MEDLINE (1966 to March 2006), EMBASE (1980 to March 2006), Current Contents (1993 to March 2006), the National Research Register, and the National Library of Medicine's Clinical Trial Register (up to March 2006).

SELECTION CRITERIA

Only randomised controlled trials (RCTs) that compared interventions to reduce blood loss during myomectomy to placebo or no treatment were included.

DATA COLLECTION AND ANALYSIS

The two authors independently selected RCTs for inclusion, assessed the methodological quality and extracted data. We expressed study results as weighted mean differences (WMD) for continuous data, and odds ratios for dichotomous data.

MAIN RESULTS

Eight RCTs met the inclusion criteria: two on intramyometrial vasopressin and analogues, and one each on vaginal misoprostol, IV oxytocin, pericervical tourniquet, chemical dissection with mesna, intramyometrial bupivacaine plus epinephrine and the enucleation of myoma by morcellation while it is attached to the uterus. We found significant reductions in blood loss with misoprostol (WMD -149.00 ml, 95% confidence interval [CI] -229.24 to -68.76), vasopressin and analogues (WMD -298.72 ml, 95% CI -593.10 to -4.34), bupivacaine plus epinephrine (WMD -68.60 ml, 95% CI -93.69 to - 43.51), and pericervical tourniquet (WMD -1870.00 ml, 95% CI -2547.16 to -1192.84). There was no evidence of effect in blood loss with myoma enucleation by morcellation and oxytocin. The trials did not assess the tolerability and costs of different interventions.

AUTHORS' CONCLUSIONS

There is limited evidence from a few RCTs that misoprostol, vasopressin, bupivacaine plus epinephrine, tourniquet and mesna may reduce bleeding during myomectomy. There is no evidence that oxytocin and morcellation have an effect on intraoperative blood loss. There is need for adequately powered RCTs to shed more light on the effectiveness, safety and costs of different interventions in reducing blood loss during myomectomy.

Dyspareunia

Dyspareunia, better termed women's sexual pain, is a poorly understood disorder once believed to be purely psychologic. Thanks to cooperative research efforts from several specialties toward defining subsets of the disorder, understanding the etiology of subsets and their comorbidities and new concepts for diagnosis and management are being validated or are being put into practice. This review describes the surprising prevalence of sexual pain, outlines new definitions for subtypes of sexual pain and diagnostic criteria for them, and applies these diagnoses to the task of selecting treatment options.

Retrospective cost analysis comparing Essure hysteroscopic sterilization and laparoscopic bilateral tubal coagulation

STUDY OBJECTIVE

To compare the institutional cost of permanent female sterilization by Essure hysteroscopic sterilization and laparoscopic bilateral coagulation.

DESIGN

Retrospective cohort study (Canadian Task Force classification II-2).

SETTING

Midwestern academic medical center.

PATIENTS

Women of reproductive age who elected for permanent contraception by the Essure method (n = 43) or by laparoscopic tubal coagulation (n = 44) during the time frame studied.

INTERVENTIONS

Placement of the Essure inserts according to the manufacturer's instructions or laparoscopic tubal sterilization using bipolar forceps according to standard techniques of open or closed laparoscopy.

MEASUREMENTS AND MAIN RESULTS

Cost-center data for the institutional cost of the procedure was abstracted for each patient included in the study. In addition, demographic data and procedural information were obtained and compared for the patient populations. The Essure system of hysteroscopic sterilization had a significantly decreased cost compared with laparoscopic tubal sterilization when both procedures were performed in an operating room setting. The decrease per patient in institutional cost was 180 dollars (p = .038). This included the cost of the confirmatory hysterosalpingogram 3 months after Essure placement and the cost of laparoscopic tubal occlusion by Filshie clip if the Essure micro-inserts could not be placed. The majority of the cost was related to hospital costs as opposed to physician costs. The Essure procedure had higher costs for disposable equipment (p <.0001), but this was offset by higher charges for operating room costs, which included the recovery room (p <.0001) and pharmacy costs (p <.0001) in the patients in the laparoscopy group.

CONCLUSION

In our setting, the Essure hysteroscopic sterilization had significant cost savings compared with laparoscopic tubal sterilization (p = .038). We believe that our data represent the minimum of potential savings using this approach, and future developments will only increase the cost difference found in our study.

Multiple leiomyomas after laparoscopic hysterectomy: Report of two cases

We report on 2 cases of multiple leiomyomas arising in the pelvis after laparoscopic hysterectomy. One patient underwent laparoscopic myomectomy at 41 years of age and subsequently had a total laparoscopic hysterectomy for myomas 4 years later. Three years post-hysterectomy, she presented with pelvic masses that were removed laparoscopically and were leiomyomas on histopathologic examination. The other patient underwent supracervical hysterectomy for myomas with removal of a parasitic myoma from underneath the dome of the diaphragm. Eight months post-hysterectomy, she came to our office with a pelvic mass with a large myoma that was removed laparoscopically. Disseminated leiomyomas may occur after hysterectomy; and though various theories have been proposed to explain this remarkable entity, none has found universal acceptance. A thorough MEDLINE search did not reveal any reports of large pelvic masses of this size after hysterectomy or their management laparoscopically, and these are probably the first reported cases.

Minilaparotomy hysterectomy assisted by self-retaining elastic abdominal retractor

STUDY OBJECTIVE

To verify the efficacy and safety of minilaparotomy hysterectomy using a self-retaining elastic abdominal retractor.

DESIGN

Retrospective study (Canadian Task Force classification II-3).

SETTING

Private hospital, department of obstetrics and gynecology.

PATIENTS

One-hundred-fifty women, age 37 to 76 years, with benign uterine pathology or preinvasive neoplasia.

INTERVENTION

Minilaparotomy hysterectomy assisted by a self-retaining elastic abdominal retractor.

MEASUREMENTS AND MAIN RESULTS

The mean surgical time was 70 +/- 23.5 minutes (95% CI 63.1-70.7). There were no intraoperative complications. There was no need to extend the initial incision. Eight patients developed complications during the immediate postoperative period (fever in 2, hematoma of the surgical wound in 2, sub-aponeurotic seroma in 2, pubic edema in 1, and pulmonary embolism in 1). During the late postoperative period, a vaginal cuff dehiscence was reported. Mean postoperative hospital stay was 2.5 +/- 0.2 days (95% CI 2.4-2.6).

CONCLUSION

Minilaparotomy hysterectomy assisted by a self-retaining abdominal elastic retractor is a safe and effective minimally invasive procedure. Also, it appears to be a good alternative to laparoscopic hysterectomy for institutions that do not have the required expensive equipment or for gynecologists who do not have laparoscopic experience.

Endometrial cancer and its management

Endometrial cancer is an increasingly common cancer in affluent Western countries, largely due to the increasing obesity of those populations. Type I endometrial cancer is the more common phenotypic picture, being that of an obese postmenopausal woman, and comprises approximately 80% of endometrial cancers. Type II endometrial cancer describes a woman who is often younger and thinner, with a more aggressive histological type that is non-estrogen dependent, of either serous or clear-cell histology, and has a more aggressive clinical course and resultant poorer prognosis. The standard surgical procedure is an extrafascial total hysterectomy with bilateral salpingo-oophorectomy, with or without pelvic and para-aortic lymphadenectomy. The safety of a laparoscopic approach in the surgical management of uterine cancer has not yet been demonstrated in prospective randomized trials. Surgical staging of endometrial cancer, including a pelvic and para-aortic lymphadenectomy, allows appropriately tailored postoperative radiotherapy. Teletherapy or vaginal brachytherapy may reduce the risk of pelvic recurrent disease in high-risk patients.

Endometriosis: the way forward

Endometriosis, a common cause of morbidity, affects 10% of women of reproductive age. In this review we focus on the new developments in pathogenesis, diagnosis and treatment options, reviewing the literature published about this enigmatic disorder over the past three years. More specifically, new theories of the pathogenesis of the syndrome of Sampson and Cullen are discussed. The new era of genomics may characterize endometriosis and transform clinical management of the disease. Literature suggesting that endometriosis may have an environmental origin is reviewed. New approaches to medical therapy of endometriosis have been developed, including the levonorgestrel-releasing intrauterine device, aromatase inhibitors, immunomodulatory drugs, angiogenesis inhibitors, selective estrogen and progesterone receptor modulators, and statins. Subfertility is another well-known result of endometriosis and often complex decisions must be made regarding management of the endometriosis patient who wishes to conceive. Laparoscopic surgery and assisted reproduction--with or without gonadotropin-releasing hormone-agonist treatment--are reviewed. Finally we speculate about new developments in the field of endometriosis in the coming three years.

[Radiologically-guided hysterosalpingography and tubal catheterization]

Radiological exploration of hypofertility by means of hysterosalpingography is a method still valid but no longer sufficient. Tubal catheterization has thus become a necessary complementary exam in order to eliminate the pseudo-obturations of hysterosalpingography and, in case of proximal tubal obstructions, to obtain pregnancies. The conditions for the realization of hysteroalpingography and tubal catheterization are hereby described, with emphasis on the rigorous technique that is required together with careful listening to the patients.

Surgical routes and complications of hysterectomy for benign disorders: a prospective observational study in French university hospitals

BACKGROUND

Despite the advantages of the vaginal and laparoscopic approaches, most hysterectomies carried out involve laparotomy. The objective of this prospective observational multicentre study was to examine the routes and complications of hysterectomy for benign disorders.

METHODS

Of the 15 university hospitals belonging to Collégiale de Gynécologie-Obstétrique de Paris-Ile de France, 12 participated in this study that took place between June and December 2004. We analysed the characteristics of the patients, the indications for hysterectomy and intra- and post-operative complications (and their determinants) according to the surgical approach.

RESULTS

In total, 634 women underwent hysterectomy for benign disorders during the study period. The patients' mean age (+/-SD), BMI, parity and previous Caesarean sections were 51.4 +/- 10.3 years, 25 +/- 5.7 kg/m(2), 2 +/- 1.6 children and 0.2 +/- 0.6, respectively. Hysterectomy was performed by the laparoscopic, laparoscopically assisted vaginal hysterectomy (LAVH), laparotomic and vaginal routes in 19.1, 8.2, 24.4 and 48.3% of cases, respectively. The operating time was shorter with the vaginal route than with laparoscopy, laparotomy and LAVH (P < 0.0001). Intra- and post-operative complications were significantly more frequent in the laparotomic group (18%) compared with the vaginal group (8.2%), the laparoscopic group (5.8%) and the LAVH group (8.2%) (P < 0.0001). In a multivariate logistic regression model, obesity [odds ratio (OR): 2.84, 95% confidence interval (CI): 1.53-5.27, P = 0.001], history of pelvic surgery (OR: 2.47, 95% CI: 1.39-4.39, P = 0.002) and history of Caesarean section (OR: 2.04, 95% CI: 1.01-4.1, P = 0.046) were significantly associated with intra- and post-operative complications. Laparoconversion was necessary in 36 cases (7.5%) overall and was more frequent with laparoscopy and LAVH than with the vaginal route (P < 0.0001).

CONCLUSIONS

This study confirms that the vaginal route is increasingly used for hysterectomy in France and that it is the route of choice for benign disorders.

Perioperative Predictors of Successful Hysteroscopic Endometrial Ablation

OBJECTIVE

To determine which perioperative factors influence the success of hysteroscopic endometrial ablation in patients with menorrhagia.

STUDY DESIGN

A longitudinal study of 128 women who underwent hysteroscopic endometrial ablation or resection. Clinical data included age, uterine size, the presence of intramural or submucosal myomas and polyps, and length of follow-up from initial hysteroscopic ablation to re-ablation or hysterectomy ('failure'). Kaplan-Meier survival analysis, log-rank tests and Cox proportional hazard regression were used to evaluate the equality of survival distributions and to model the overall effects of the various predictor variables on surgical outcomes.

RESULTS

Patients were followed for a median time of 44 months. Thirteen women (10.2%) underwent a second operative procedure. Multivariate analysis identified submucosal myoma as a statistically significant positive predictor of the risk of failure [hazard ratio (HR) 5.22, 95% confidence interval (CI) = 1.63, 16.73)]. Older age was associated with a marginally lower risk of subsequent surgery (HR 0.90 per additional year of age, 95% CI = 0.81, 1.00).

CONCLUSIONS

The presence of submucosal myoma increases the risk of subsequent surgery in patients undergoing endometrial ablation.

Percutaneous Image-guided Radiofrequency Thermal Ablation for Large Symptomatic Uterine Leiomyomata after Uterine Artery Embolization: A Feasibility and Safety Study

PURPOSE

To evaluate the feasibility and safety of percutaneous image-guided radiofrequency ablation (RFA) performed with moderate sedation for large symptomatic uterine leiomyomata.

MATERIALS AND METHODS

Women with large (>5 cm in diameter) symptomatic subserosal and/or intramural uterine leiomyoma were recruited for a prospective study. Patients underwent percutaneous RFA following UAE. RFA using 5 cm treatment diameter expandable needle electrodes connected to a 460 kHz monopolar RF generator, which was performed with a target temperature and power set at 85 degrees C and 150 watts respectively, with a target temperature ablation time of 10 minutes. Patients were assessed for complications in perioperative and post-procedure periods at 24 hours and 1 month, and for symptom improvements at 6 months.

RESULTS

Thirty-five patients (mean 43.8 years +/- 6.2) were recruited. RFA targeting ablation size and temperature was achieved in 97% of the patients (34/35). There were no immediate percutaneous RFA-related complications. There was a self-limiting delayed drainage via the transabdominal RFA access track in one patient (2.9%), a urinary tract infection in one patient (2.9%) and post-embolization/post-ablation symptoms in three patients (8.6%). The mean transformed symptom severity score (SSS) as a part of the uterine fibroid symptom and quality of life (UFS-QOL) assessment shows that the improvements at 1 month were 24.3 points ( P < 0.001) and at 6 months were 40.4 points ( P < 0.001). Mean volume reduction of leiomyomata was 286.8 cm(3) or 56.5% ( P = 0.0015).

CONCLUSIONS

Percutaneous image-guided RFA as adjunctive to UAE under moderate sedation is feasible, and appears safe without significant morbidity in the treatment of large uterine leiomyomata.

Teach the teachers: an observational study on mentor traineeship in gynecological laparoscopic surgery

BACKGROUND

To evaluate the effect of a mentor traineeship in laparoscopic surgery in a teaching hospital.

METHOD

This observational study was performed between January 1997 and December 2004 at Bronovo Hospital, The Hague, The Netherlands. Since January 2001, an advanced endoscopic gynecologist has mentored a trainee in laparoscopic surgery. Data on the trainee's procedures preceding (1997-2000) and during the mentor traineeship (2001-2004) were compared. The number and type of procedures performed, complications and conversions were derived from a prospectively kept database supplemented by a retrospective chart review. Operating times for total laparoscopic hysterectomy (TLH) were registered to establish the trainee's learning curve.

RESULTS

Since the presence of a mentor, the trainee has performed significantly more advanced laparoscopic procedures. Despite the significant increase in advanced cases, the trainee's laparoscopic conversion rate to laparotomy remained stable between period 1 and period 2 (7.5 and 4.5%, respectively, p = 0.35, 95% CI -0.033 to 0.092); moreover, for level-3 procedures the conversion rate decreased (p < 0.001, 95% CI 0.30-0.71). Despite the increase in advanced cases, the total complication rate remained stable (3.2-4.5%, p = 0.62, 95% CI -0.07 to 0.04) including the number of level-3 complications (p = 0.63, 95% CI -0.4 to 0.3). A decreasing trend in operating time for TLH was found; however, this was not significant (Spearman correlation coefficient -0.421, p = 0.81).

CONCLUSIONS

Mentor traineeship in gynecology enhanced the advanced laparoscopic caseload. With the increase in advanced procedures, no increase in conversion rate, complication rate or operating times for TLH was found. Due to the mentorship, patients were not exposed to increased complications and conversions, or to the disadvantages of a prolonged operating time. Predominantly, mentor traineeship facilitated the implementation of laparoscopic surgery into an established gynecological practice in a teaching hospital.

Deep dyspareunia and sex life after laparoscopic excision of endometriosis

BACKGROUND

Among subjects with endometriosis and deep dyspareunia (DD), those with endometriosis of the uterosacral ligament (USLE) have the most severe impairment of sexual function. This study examines the effect of laparoscopic excision of endometriosis on DD and quality of sex life.

METHODS

This observational cohort prospective study included 68 women with endometriosis suffering DD (intensity of pain >or= 6 on a 10-cm visual analogue scale). Patients underwent laparoscopic full excision of endometriosis. Following surgery, they were asked to use nonhormonal contraception devices. Before surgery, at 6- and at 12-month follow-up, patients answered a self-administered questionnaire based on the Sexual Satisfaction Subscale of the Derogatis Sexual Functioning Inventory.

RESULTS

At 6- and 12-month follow-up, women with and without USLE had significant improvement in DD. Subjects with USLE reported increased variety in sex life, increased frequency of intercourse, more satisfying orgasms with sex, relaxing more easily during sex and being more relaxed and fulfilled after sex. Similar improvements were observed among women without USLE; however, for some variables statistical significance was not reached.

CONCLUSIONS

Surgical excision of endometriosis improves not only DD but also the quality of sex life.

Intraperitoneal aerosolization of bupivacaine reduces postoperative pain in laparoscopic surgery: a randomized prospective controlled double-blinded clinical trial

BACKGROUND

Laparoscopic strategies for managing intraabdominal pathologies offer significant benefits compared with conventional approaches. Of interest are reports of decreased postoperative pain, resulting in shorter hospitalization and earlier return to normal activity. However, many patients still require strong analgesia postoperatively. This study analyzed the use of intraoperatively delivered aerosolized intraperitoneal bupivacaine and its ability to reduce postoperative pain.

METHODS

For this study, 80 patients undergoing laparoscopic cholecystectomy were recruited and divided randomly into four groups: control (n = 20), aerosolized bupivacaine (n = 20), aerosolized normal saline (n = 20), and local bupivacaine in the bladder bed (n = 20). All the patients had standard preoperative, intraoperative, and postoperative care. Pain scores were recorded by the nursing staff in recovery, then 6, 12, and 24 h postoperatively using a standard 0 to 10 pain scoring scale. In addition, opiate consumption and oral analgesia were recorded.

RESULTS

Aerosolized bupivacaine significantly reduced postoperative pain in comparison with all other treatments (p < 0.05). Injection of bupivacaine into the gallbladder bed did not result in a significant difference from the control condition.

CONCLUSION

Aerosolized intraperitoneal local anesthetic is an effective method for controlling postoperative pain. It significantly helped to reduce opiate use and contributed to rapid mobilization, leading to short hospitalization and possible reduction in treatment cost.

From the archives of the AFIP: Inflammatory and nonneoplastic bladder masses: radiologic-pathologic correlation

Although the vast majority of bladder tumors are epithelial neoplasms, a variety of nonneoplastic disorders can cause either focal bladder masses or diffuse mural thickening and mimic malignancy. Some of these entities are rare and poorly understood such as inflammatory pseudotumor, which produces ulcerated, bleeding polypoid bladder masses. These masses may be large and have an extravesical component. Bladder endometriosis manifests as submucosal masses with characteristic magnetic resonance imaging features consisting of hemorrhagic foci and reactive fibrosis. Nephrogenic adenoma has no typical features, and pathologic evaluation is required for diagnosis. Although imaging features of malacoplakia are also nonspecific, characteristic Michaelis-Gutmann bodies are found at pathologic evaluation. The various types of cystitis (cystitis cystica, cystitis glandularis, and eosinophilic cystitis) require pathologic diagnosis. Bladder infection with tuberculosis and schistosomiasis produces nonspecific bladder wall thickening and ulceration in the acute phase and should be suspected in patients who are immunocompromised or from countries where these infections are common. The diagnosis of chemotherapy cystitis and radiation cystitis should be clinically evident, but imaging may be used to determine severity and to assess complications. Extrinsic inflammatory diseases such as Crohn disease and diverticulitis may be associated with fistulas to the bladder and focal bladder wall abnormality. The extravesical findings allow the diagnosis to be made easily. Finally, extrinsic masses arising from the prostate or distal ureter may cause filling defects, which can be confused with intrinsic bladder masses.

Bowel endometriosis: CT-enteroclysis

Although several radiological techniques have been used for the diagnosis of bowel endometriosis, no gold standard is currently established. We used multislice computerized tomography (CT) combined with the distention of the colon by rectal enteroclysis (MSCTe) for the diagnosis of bowel endometriosis. Following bowel preparation, pharmacological hypotonicity, retrograde colonic distention by water enteroclysis, and intravenous injection of iodinated contrast medium, a single volumetric acquisition of the abdomen is performed. MSCTe findings suggestive of bowel endometriosis are the presence of solid nodules with positive enhancement, contiguous or penetrating the colonic wall. When endometriotic lesions are detected, the degree of infiltration of the intestinal wall can be estimated; however, the depth infiltrated by nodules reaching the submucosa may be underestimated. MSCTe is well tolerated by the patients. The strength of MSCT consists in the high spatial resolution; volumetric data acquired by using thin slices provide isotropic voxels and multiplanar reconstructions have a quality comparable with that of the original axial scans. The potential of MSCTe for the diagnosis of bowel endometriosis relies on the fact that the serosal, muscular, and mucosal layers of the bowel wall can be evaluated.

Myolysis of Uterine Fibroids: Is There a Role?

Myolysis is among the new procedures under development for the treatment of symptoms related to uterine leiomyoma. The procedure targets the destruction of fibroids using one of a number of focused energy delivery systems including those based upon radiofrequency electricity, supercooled cryoprobes, and, most recently, focused ultrasound monitored by real time magnetic resonance imaging. For thermomyolysis and cryomyolysis, delivery of the energy requires access to the tissue by laparoscopy, and, in some instances, hysteroscopy. For focused ultrasound, the patient is detached from the energy source, which is delivered by an array of external beams. Clinical evaluation has been confined to case series, but it is evident that the approach results in a variable degree of reduction of the total uterine mass, and, usually, a reduction in uterine bleeding. Clearly, longer term appropriately designed comparative trials are required that evaluate and compare myolysis with myomectomy, uterine artery embolization, and hysterectomy, to name a few.

Hysterectomy in the 21st Century: Different Approaches, Different Challenges

The final decision to perform a certain method of hysterectomy customarily mirrors experience and level of comfort with a particular surgical approach in the context of the patient's condition and indication for surgery. Given the morbidity and recovery associated with a laparotomic incision, every effort should be made to avoid abdominal hysterectomy. The best available evidence points to the advantage of the vaginal approach over other methods of hysterectomy for benign conditions. Regrettably, the state of education in residency programs is not providing a level of surgical competency to meet this charge. Whenever vaginal surgery is not an option, laparoscopically assisted hysterectomy offers the best alternative. Although the promises of supracervical hysterectomy have yet to be demonstrated, laparoscopic supracervical hysterectomy may offer the least morbid alternative to vaginal hysterectomy.

Endometrial Ablation: Where Have We Been? Where Are We Going?

Endometrial ablation (EA) is targeted destruction of the endothelial surface of the uterine cavity. The procedure was originally designed as a less invasive alternative to hysterectomy for the symptom of heavy menstrual bleeding unrelated to structural pathology of the uterus, that was not responsive to medical therapy. More recently it has become apparent that the procedure can be performed in the presence of submucous leiomyomas, providing they meet a number of size and location criteria. The first EA serie as published in Germany in the 1930s, but the procedure did not attract much attention until the latter part of the 20th century. Currently, EA can be performed under endoscopic direction with the neodymium:yttrium alumnum garnet laser, with a radiofrequency resectoscope, or with an expanding array of nonresectoscopic EA systems. It is apparent that most but not all of the complications associated with resectoscopic endometrial ablation are eliminated with nonresectoscopic endometrial ablation, but serious morbidity has been reported with all of the newer systems to date. Success and patient satisfaction seem to be enduring in the majority of well-selected patients treated in clinical trials, but repeat surgery, usually hysterectomy, is performed in 25% to 40% by 5 years after surgery. Increased efficiencies should be realized if the procedure could be moved to an office setting.

The Evolution of Uterine Surgery

Although described in antiquity, the real dawn of uterine surgery was in the mid-19th century when hysterectomy was occasionally performed vaginally, usually for cancer or prolapse. Then, as now, women experienced symptoms of bleeding and pain emanating from the uterus, and when severe and debilitating, brave surgeons and patients sometimes explored hysterectomy as an alternative. Abdominal hysterectomy mortality rates in the mid-1850s were extremely high, but reduced drastically in the early to mid-20th century. By the 1950s, total hysterectomy supplanted supracervical techniques, largely as a method for preventing carcinoma of the cervix. Surgical alternatives to hysterectomy started in the 1930s with abdominal myomectomy and the first publication of nonhysteroscopic endometrial ablation from Germany, but by the end of the 20th century, included a plethora of techniques including laparoscopic, hysteroscopic, and interventional radiologic approaches. The advent of early detection of, and even prevention of, preinvasive cervical neoplasia, has led to a reevaluation of the need for total hysterectomy in many patients. In the early years of the millennium, targeted leiomyoma therapy was under development with a range of energy sources including cryogenic and radiofrequency probes, as well as focused ultrasound, targeted and controlled by magnetic resonance imaging.

Laparoscopic Myomectomy and Abdominal Myomectomy

Most women develop myomas during their lifetimes; however, 80% are asymptomatic. When symptoms are determined to be caused by myomas, a number of management options exist that include "watchful waiting," medical therapy, surgery, or more recently uterine artery embolization and focused ultrasound. Myomectomy, either abdominal or laparoscopic, is an approach particularly suited for those women who wish future fertility. It seems clear that, in well trained and experienced hands, well-selected patients can have myomectomy performed under laparoscopic direction. Very large myomas are not as suitable for the laparoscopic approach, but are amenable to a uterine conserving procedure via laparotomy that is facilitated by a number of preoperative and intraoperative measures aimed to minimize or replace operative blood loss. These techniques should provide selected women a uterine conserving procedure with reduced morbidity.

Cross-organ interactions between reproductive, gastrointestinal, and urinary tracts: modulation by estrous stage and involvement of the hypogastric nerve

Central nervous system neurons process information converging from the uterus, colon, and bladder, partly via the hypogastric nerve. This processing is influenced by the estrous cycle, suggesting the existence of an estrous-modifiable central nervous system substrate by which input from one pelvic organ can influence functioning of other pelvic organs. Here, we tested predictions from this hypothesis that acute inflammation of colon, uterine horn, or bladder would produce signs of inflammation in the other uninflamed organs (increase vascular permeability) and that cross-organ effects would vary with estrous and be eliminated by hypogastric neurectomy (HYPX). Under urethane anesthesia, the colon, uterine horn, or bladder of rats in proestrus or metestrus, with or without prior HYPX, was treated with mustard oil or saline. Two hours later, Evans Blue dye extravasation was measured to assess vascular permeability. Extravasation was increased in all inflamed organs, regardless of estrous stage. For rats in proestrus, but not metestrus, either colon or uterine horn inflammation significantly increased extravasation in the uninflamed bladder. Much smaller cross-organ effects were seen in colon and uterine horn. HYPX reduced extravasation in the inflamed colon and inflamed uterine horn, but not the inflamed bladder. HYPX eliminated the colon-to-bladder and uterine horn-to-bladder effects. These results demonstrate that inflaming one pelvic organ can produce estrous-modifiable signs of inflammation in other pelvic organs, particularly bladder, and suggest that the cross-organ effects involve the hypogastric nerve and are at least partly centrally mediated. Such effects could contribute to cooccurrence and cyclicity of distressing pelvic disorders in women.

Hysteroscopic Treatment of Submucous Myomas

Submucous myomas can cause heavy bleeding, pain, and infertility. Sonohysterography and office hysteroscopy can provide accurate diagnosis. Classification systems have been developed to help predict the difficulty of resection. Patient selection and proper surgical technique are essential to achieve good results and reduce the risk of complications. Hysteroscopic treatment can in many cases provide excellent results and eliminate the need for major surgery.

Outcome of tension-free vaginal tape procedure when complicated by intraoperative cystotomy

OBJECTIVE

The objective of this study was to determine risk factors for intra-operative cystotomy during TVT and whether this affects surgical outcome and morbidity.

STUDY DESIGN

Charts of 340 women who underwent TVT were reviewed. Those who had a cystotomy during the procedure (cases) were compared with those without (controls) for the variables: age, race, parity, body mass index (BMI), TVT with or without other procedures, previous pelvic surgery, blood loss, length of catheter drainage, UTI, and voiding dysfunction. The t-test and chi-squared test were used and differences resulting in P < .05 were statistically significant.

RESULTS

Cystotomy occurred in 49/340 TVT procedures (14.4%). Only those who had a history of abdominal hysterectomy and BMI greater than 26.5 were more likely to have a cystotomy (P = .05 and P = .001, respectively). Cases were more likely to go home with catheter drainage (P = .005). There was no increased risk of UTI or voiding dysfunction, nor was there a difference in surgical cure rate.

CONCLUSION

Cystotomy does not seem to negatively affect the outcome of the TVT procedure.

Challenges to our understanding of endometriosis pain

Endometriosis remains a diagnostic and therapeutic challenge despite decades of clinical experience and research. The multiple treatment options for endometriosis described in this symposium clearly indicate how difficult it can be to diagnose and effectively treat endometriosis with our current understanding of the disease. At least 3 major challenges to our understanding can be identified: (1) endometriosis does not always cause pain; (2) other causes of pelvic pain often coexists in patients with endometriosis; and (3) common medical and surgical treatments for endometriosis are relatively nonspecific. Insights from the articles in this symposium can help clinicians reach a new level of understanding of endometriosis and perhaps lead to more effective methods for diagnosing and treating this perplexing condition.

Impact of diagnostic laparoscopy on the management of chronic pelvic pain

BACKGROUND

Diagnostic laparoscopy is a useful tool, especially when there is no definite anatomical abnormality visible on imaging modalities. We assess the role and clinical impact of diagnostic laparoscopy in the management of women with chronic pelvic pain.

METHODS

Clinical data of 3,068 cases of diagnostic laparoscopy performed for chronic pelvic pain from June 1994 to August 2005 were analyzed. We compared the diagnoses after diagnostic laparoscopy and those after pelvic examination and imaging modalities such as ultrasound or computed tomography (CT), and we then checked the final pathologic diagnoses after operation.

RESULTS

Pelvic endometriosis was the most common (60.2%) laparoscopic finding in patients with chronic pelvic pain in this study, followed by normal pelvic findings (21.2%) and pelvic congestion (13.0%). Diagnostic laparoscopy had an influence on correcting previous plans based on imaging modalities in 42.7% of patients such as discarding unnecessary procedures or introducing new diagnostic or therapeutic plans. There were 3 cases of major complications requiring immediate correction.

CONCLUSIONS

Diagnostic laparoscopy is a useful diagnostic tool for of women with chronic pelvic pain and can be used as a guideline for individualized treatment.

Hysterectomy for treatment of pain associated with endometriosis

The literature was searched for endometriosis and hysterectomy on PubMed and the individual search engines of the Journal of Minimally Invasive Surgery, Fertility and Sterility, BJOG, Obstetrics and Gynecology, the American Journal of Obstetrics and Gynecology, and Human Reproduction. Eighty references of interest were identified and included in this review. Analysis of hysterectomy for pain associated with endometriosis is difficult for many reasons. These include a lack of differentiation of various forms of cyclic pain from other forms of non-cyclic pain, the retrospective nature of much of the literature, and a low specificity for identifying pain. Hysterectomy for chronic non-specified pelvic pain associated with endometriosis is a successful approach in many women. It can not be determined whether this is due to intermingling of patients with and without cyclic pain or if both of these respond equally well. Focused prospective research is needed to determine whether symptoms, signs, or laboratory findings might be useful in determining more specific response patterns.

Isobaric (gasless) laparoscopic uterine myomectomy

The aim of this review has been to assess the usefulness and effectiveness of isobaric (gasless) laparoscopic myomectomy using a subcutaneous abdominal wall lifting system, and to evaluate the advantages and disadvantages of this technique in comparison with the conventional laparoscopic myomectomy using pneumoperitoneum. Laparoscopy using CO2 is more frequently employed for small or medium-sized myomas. Furthermore, multiple myomectomies (>or=3 myomas per patient) are performed rarely. Gasless laparoscopy permits the removal of large intramural myomas overcoming the difficulties associated with laparoscopic myomectomy using pneumoperitoneum. It appears to offer several advantages over conventional laparoscopy, such as elimination of the adverse effects and potential risks associated with CO2 insufflation; use of conventional laparotomy instruments that facilitate several steps of the procedure; reduced operative times and costs. Indeed, this procedure associates the advantages of laparoscopy and minimal access surgery with those of using the laparotomic instruments that are more reliable for uterine closure. The only advantage of the laparoscopy with pneumoperitoneum is the tamponade effect generated by the gas on the small vessels, thus reducing intraoperative bleeding. Laparoscopic myomectomy using CO2 remains the preferred minimally invasive approach for small and medium-sized myomas and when the total number of myomas removed does not exceed 2 or 3. Gasless laparoscopic myomectomy could be mainly indicated for removal of large intramural myomas (>or=8 cm) and/or for multiple myomectomies (>or=3 myomas per patient). Anyhow, further controlled studies are needed to evaluate entirely their respective indications.

The role of magnetic resonance imaging in minimal access surgery

PURPOSE OF REVIEW

Magnetic resonance imaging is commonly used for gynaecological malignancies, but also is increasingly used for the investigation of benign gynaecological complaints. This review summarizes the current evidence regarding its use as an adjunct to minimal access surgery for endometriosis, adenomyosis, adhesions and fibroids.

RECENT FINDINGS

Magnetic resonance imaging appears to be equal in efficacy to ultrasound for the diagnosis of both fibroids and endometriosis, and perhaps superior for the diagnosis of adenomyosis. It is extremely useful for the preoperative investigation of severe endometriosis, especially recto-vaginal disease. Milder endometriosis is, however, still difficult to diagnose by either ultrasound or magnetic resonance imaging. Magnetic resonance imaging can also be helpful for the detection of adhesions, pelvic collections, congenital defects and fibroids. It is also useful following fibroid embolization.

SUMMARY

Currently, it is not cost-effective to use magnetic resonance imaging as the modality of first choice when investigating pelvic pain and or menstrual disorders. If preoperative patients are carefully selected, however, it can substantially reduce surgical morbidity by using it to diagnose severe endometriosis and adhesions which may lead to cost savings overall.
