Surgical management of endometriosis.

A systematic literature review of the last two decades was performed to evaluate the effect of pelvic denervations in addition to conservative surgery on dysmenorrhoea and deep dyspareunia associated with endometriosis. Chronic pelvic pain relief after hysterectomy or adhesiolysis was also assessed. In the five non-comparative studies on the effect of pre-sacral neurectomy, the frequency of dysmenorrhoea recurrence or persistence after treatment ranged from 4 to 40%. The pooled frequency of non-responders at the end of follow-up was 23% (95% confidence interval (CI), 19 to 27%). Only two of the three comparative, non-randomized trials demonstrated a significant treatment benefit of pre-sacral neurectomy, and the results of the two identified randomized controlled trials are discordant. Significant quantitative heterogeneity among studies prevented pooling of data on dysmenorrhoea. The common odds ratio of deep dyspareunia persistence was 0.69 (95% CI, 0.31 to 1.54). In the 10 non-comparative studies on the effect of uterosacral ligament resection, the frequency of dysmenorrhoea and deep dyspareunia persistence after treatment ranged, respectively, from 0 to 50% and from 6 to 42%. The pooled frequency of non-responders at the end of follow-up was 23% (95% CI, 20 to 27%) and 13% (95% CI, 8 to 18%), respectively. Routine performance of complementary denervating procedures cannot be recommended based on the quality of the evidence available. The results of the five studies on the effect of hysterectomy on chronic pelvic pain of presumed uterine origin consistently demonstrated that 83-97% of operated women reported pain relief or improvement 1 year after surgery. There is no consensus on the outcome of adhesiolysis in patients with chronic pain, and the role of pelvic adhesions in causing symptoms is under scrutiny.

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

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

Lateral distribution of nonendometriotic benign ovarian cysts.

To investigate the left- and right-sided distribution of nonendometriotic benign ovarian cysts, data were collected on 406 women undergoing first-line surgery for tumours with various histotypes. Considering the unilateral cysts, the observed proportion of left lesions was 65/129 (50.4%) in the serous, 38/79 (48.1%) in the mucinous, 59/134 (44.0%) in the dermoid, 11/21 (52.4%) in the parovarian, and 3/7 (42.9%) in the miscellaneous cysts group, without significant differences from the expected 50%. This contrasts with the finding of a significantly more frequent development of endometriomas on the left ovary, and suggests that the pathogenesis of endometriotic and nonendometriotic cysts is different.

Is ureteral endometriosis an asymmetric disease?

Six cases of endometriosis obstructing the left ureter were observed among 1,054 consecutive patients undergoing surgery in an eight-year period. In addition, 125 women with ureteral endometriosis (left-sided, n = 66; right-sided, n = 40; bilateral, n = 19) were described in 62 articles identified in a systematic review of the English language literature between 1980 and 1998. Considering only the patients with unilateral ureteral endometriosis and combining the published figures with those of our surgical series, the observed proportion of left lesions (72/112, 64%; 95% CI 55% to 73%) was significantly different from the expected proportion of 50% (chi2(1), 9.14, P = 0.002). The lateral asymmetry found in the location of ureteral endometriosis is compatible with the menstrual reflux theory and with the anatomical differences of the left and right hemipelvis.

Hysteroscopic myomectomy: long-term effects on menstrual pattern and fertility.

OBJECTIVE: To determine the effects of hysteroscopic myomectomy on menorrhagia and infertility and the influence of intramural extension on surgical feasibility and long-term outcomes. METHODS: We studied 108 women who had first-line hysteroscopic resection of submucous pedunculated (n = 54), sessile (n = 30), or intramural (n = 24) leiomyomas over 7 years at an academic department specializing in endoscopic surgery. RESULTS: The mean (+/- standard deviation) operating time and distension medium deficit were 18+/-7 minutes and 204+/-276 mL in the pedunculated lesion group, 23+/-9 minutes and 278+/-269 mL in the sessile lesion group, and 32+/-8 minutes and 335+/-272 mL in the intramural lesion group, respectively. More than one procedure was required to complete myoma removal in 14 (26%) of 54, eight (26%) of 30, and 12 (50%) of 24 subjects in the pedunculated, sessile, and intramural lesion groups, respectively. After a mean follow-up of 41 months, myomas recurred in 27 subjects, with a 3-year cumulative rate of 34%. Twenty women had recurrent menorrhagia, with a 3-year cumulative probability of 30%. The 3-year cumulative probability of conception was 49% in women with pedunculated lesions, 36% in those with sessile lesions, and 33% in those with intramural lesions. The study had 80% power to detect five- and three-fold increases in menorrhagia recurrence and conception rates, respectively, in the mainly intramural myoma group compared with the completely or mainly intracavitary myoma group. CONCLUSION: Hysteroscopic resection of submucous myomas gives satisfactory menorrhagia control and limited recurrence, but the benefit for infertility was less impressive. Myoma intramural extension did not have a substantial influence on any of the long-term outcomes but affected operating time and the number of procedures needed for complete removal.

Determinants of cognitive disorders in Autosomal Dominant Cerebellar Ataxia type 1.

We assessed neuropsychological performances of 22 patients affected by Autosomal Dominant Cerebellar Ataxia type 1. All subjects completed a comprehensive battery of standardized tests requiring a verbal response, without time constraints. In order to verify the hypothesis that disease severity is the major factor in determining the cognitive status in this syndrome, patients were divided into three groups according to the severity of the clinical picture, as evaluated by the Inherited Ataxias Progression Scale (IAPS). Statistical analysis of the three groups' raw scores showed a significant decrement in patients with more severe clinical pictures on verbal short-term memory tasks. A similar trend, but not significant, was seen for general intelligence tests and verbal learning tasks. The decrement of verbal short-term memory could be related to motor speech problems. On the other hand, the decline of cognitive abilities over the course of the Autosomal Dominant Cerebellar Ataxia type 1 was not homogeneous enough to ensure statistically reliable trends. Therefore, this cross-sectional study suggests that the progression of the disease is a necessary factor in determining cognitive decline, but it is not sufficient. Other disease-related factors (age at onset, genotypic variety) could play a critical role: among these, the size of the expanded CAG repeats is significantly related to a decline of verbal intelligence and short-term memory in SCA2 patients.

Evaluation of the motor cortex by magnetic stimulation in patients with Alzheimer disease.

Motor evoked potentials (MEPs) from abductor pollicis brevis (APB) and tibialis anterior (TA) muscles elicited by transcranial magnetic stimulation of the motor cortex were studied in 15 patients with Alzheimer disease (AD). An abnormally higher MEP threshold in APB, frequently associated with absence of the MEP in relaxed TA muscles, was found in 40% of patients, almost all of them in the more severe stage of the disease. The MEP amplitude and averaged MEP/MAP ratio were reduced respectively by 20% and 26% in the APB muscle, and by 46.7% and 53.3% in the TA muscle. The less frequent prolongation of the central conduction time (CCT) (20%) might reflect preservation of the impulse propagation along the surviving pyramidal fibers. In 63.6% of the patients the central silent period (cSP) duration in the APB muscle was shortened; the mean value was significantly different between patients and controls. The results of this study suggest that loss and/or dysfunction of motor cortex neurones, including pyramidal cells and inhibitory interneurones may occur in AD patients before clinical signs become apparent.
