[MINIMAL AND MILD ENDOMETRIOSIS: WHICH IMPACT ON FERTILITY?]. / ENDOMÉTRIOSE MINIME ET LÉGÈRE: QUEL IMPACT SUR LA FERTILITÉ?

Minimal and mild endometriosis (stages I/II) is frequently identified in subfertile patients, especially in case of unexplained infertility. The impact of those lesions on fecundity is still debatted and they have been considered as paraphysiological by some experts. In addition, they are heterogenous with variable spread, biological activity, induced inflammation and, sometimes, the presence of associated mild adhesions. Stages I/II endometriosis are the most frequent endometriotic lesions encountered in subfertile women. Reduced oocyte quality, anti sperm effects and, possibly, endometrial disorders appear as the most pertinent mechanisms involved. Spontaneous fecundity of women with minimal or mild endometriosis is reduced when compared to fecundity of women whose infertility is unexplained. Intra-uterine insemination with controlled ovarian stimulation improves fecundity. Laparoscopic ablation of endometriotic lesions modestly improves fecundity. This procedure has thus been recommended in view of the very small increased surgical risk. IVF is the most efficient method allowing to obtain pregnancy, with slightly reduced or similar results when compared to the performances of IVF in case of tubal infertility.

Gynaecological endoscopic evaluation of 4% icodextrin solution: a European, multicentre, double-blind, randomized study of the efficacy and safety in the reduction of de novo adhesions after laparoscopic gynaecological surgery.

BACKGROUND: Gynaecological laparoscopic surgery outcomes can be compromised by the formation of de novo adhesions. This randomized, double-blind study was designed to assess the efficacy and safety of 4% icodextrin solution (Adept(®)) in the reduction of de novo adhesion incidence compared to lactated Ringer's solution (LRS). METHODS: Patients undergoing laparoscopic surgery for removal of myomas or endometriotic cysts were treated with randomized solution as an intra-operative irrigant and 1l post-operative instillate. De novo adhesion incidence (number of sites with adhesions), severity and extent were independently scored at a second-look procedure and the efficacy of the two solutions compared. The effect of surgical covariates on adhesion formation was also investigated. Initial exploratory analysis of individual anatomical sites of clinical importance was progressed. RESULTS Of 498 patients randomized, 330 were evaluable (160 LRS--75% myomectomy/25% endometriotic cysts; 170 Adept--79% myomectomy/21% endometriotic cysts). At study completion, 76.2% LRS and 77.6% Adept had ≥ 1 de novo adhesion. The mean (SD) number of de novo adhesions was 2.58 (2.11) for Adept and 2.58 (2.38) for LRS. The treatment effect difference was not significant (P = 0.909). Assessment of surgical covariates identified significant influences on the mean number of de novo adhesions regardless of treatment, including surgery duration (P = 0.048), blood loss in myomectomy patients (P = 0.019), length of uterine incision in myomectomy patients (P < 0.001) and number of suture knots (P < 0.001). There were 15 adverse events considered treatment-related in the LRS patients (7.2%) and 18 in the Adept group (8.3%). Of 17 reported serious adverse events (9 LRS; 8 Adept) none were considered treatment-related. CONCLUSIONS: The study confirmed the safety of Adept in laparoscopic surgery. The proportion of patients with de novo adhesion formation was considerably higher than previous literature suggested. Overall there was no evidence of a clinical effect but various surgical covariates including surgery duration, blood loss, number and size of incisions, suturing and number of knots were found to influence de novo adhesion formation. The study provides direction for future research into adhesion reduction strategies in site specific surgery.

Simulation of surfactant transport during the rheological relaxation of two-dimensional dry foams.

We describe a numerical model to predict the rheology of two-dimensional dry foams. The model accurately describes soap film curvature and viscous friction with the walls, and includes the transport of surfactant within the films and across the vertices where films meet. It accommodates the changes in foam topology that occur when a foam flows and, in particular, accurately represents the relaxation of the foam following a topological change. The model is validated against experimental data, allowing the prediction of elastic and viscous parameters associated with different surfactant solutions.

Anatomic distribution of endometriosis: A reappraisal based on series of 1101 patients.

OBJECTIVE: To reappraise the anatomic distribution of endometriosis lesions in cases with Superficial Implants (SI), Ovarian Endometrioma (OMA) and Deep Infiltrating Endometriosis (DIE). MATERIALS AND METHODS: A prospective observational study was operated between January 1989 to June 2009. A total of 1333 consecutive patients with a laparoscopic diagnosis of endometriosis, were extracted from our database. Due to missing data or repeated operations, 232 patients were excluded from the study. Finally, 1101 patients who met the selected criteria were included in the present analysis.. Primary outcome of study was the anatomic location of endometriotic lesions. Secondary outcomes were laterality of lesions as well as location of adhesions. RESULTS: Mean age of patients was 33.06 years (range 15-63 years) while the mean BMI was 21.5. The ovary was the most frequent site of endometriotic lesions (737 patients, 66.94%) followed by the utero-sacral ligaments (USL) (45.51%), the ovarian fossa (32.15%), the pouch of Douglas (29.52%) and the bladder (21.25%). Deep Infiltrating Endometriosis (DIE) was diagnosed in 159 patients (14.4%) with an increasing rate starting from the mid-nineties. The left side was predominant for all locations except fromr ovarian SI and fallopian tube, but for this latter location the number of cases was limited. 600 (54.4%) patients had adhesions wjth the adnexa being the most frequent site of location (47.4%). CONCLUSIONS: Ovary was the main site of endometriotic lesions followed by the utero sacral ligaments. Left side was predominant for all locations except for ovarian SI and fallopian tube. The diagnosis of DIE has constantly being increased since mid-nineties. The large cohort of patients included in the study has strengthened previous reported data.

Clinical presentation of endometriosis identified at interval laparoscopic tubal sterilization: Prospective series of 465 cases.

OBJECTIVES: Women seeking sterilization are usually parous and have no major complains, such as pelvic pain. This could be a good model to indirectly assess the prevalence of endometriosis in the general population. Prevalence of endometriosis in women undergoing tubal sterilization by laparoscopy has been assessed in 17 published reports. Results indicate a surprising wide variation of prevalence of endometriosis, ranging from 1.4% to 43.3%. This clinical study describes the prevalence and clinical presentations of endometriosis identified at interval laparoscopic tubal sterilization, as a close representation of endometriosis in general population. MATERIAL AND METHODS: From July 1989 to February 2009, 465 women undergone interval laparoscopic tubal sterilization and were included in this series. Surgery was realised in a non universitary centre of gynecologic surgery. All patients were operated on by the same surgeon. A complete assessement of pelvic organs was achieved with a particular attention paid for endometriotic lesions. Endometriosis when present was staged according to r-AFS classification. Biopsies were sent for pathological examination to assess endometriosis. RESULTS: Mean age of women was 40.7 years (range 15-49 years). 20 women were nulliparous and 12 others had a past history of endometriosis. Endometriosis was visually identified in 55 patients (11.82%), and confirmed by histologic examination in most of cases (50/55: 90.9%). The mean age of women presenting endometriosis at the onset of tubal ligation was 41.27 years. Cases with endometriosis were classified according to the r-AFS. 39,7,8 and 1 cases corresponded to stages I, II, III and IV respectively. In the 20 nulliparous women, the prevalence of endometriosis was 20% (4/20). At the time of laparoscopic sterilization, 91 women presented a painfull condition (dysmenorrhea mainly or dyspareunia). Endometriosis was identified in 16 of them (17.58%). In the group of 360 asymptomatic parous women, the prevalence of endometriosis was 10% (36/360). Nulliparity, associated pelvic pain and retroverted uterus were associated with increased prevalence of endometriosis, without being significant. CONCLUSION: In our study, the prevalence of endometriosis identified at interval laparoscopic tubal sterilization was 11.82%. In parous asymptomatic women, the prevalence of endometriosis was 10%. The prevalence of endometriosis was slightly increased in nulliparous women, when pain was associated and in women with a retroverted uterus.

[Endometriosis coaching]. / Le coaching de l'endométriose.

Coaching is a well-known terminology and an approach currently used, particularly in the worlds of company management and sport, but its use in the medical field appeared only recently. In the latter field, coaching bears behavioral and psychological aspects. It can not only be intended to a medical team, but also the practionner himself, for a better management of any disease, his patient for a better treatment effect and compliance and an optimal coping with the disease. In the case of endometriosis, a chronic disease, two key aspects are briefly reviewed to illustrate the benefits of coaching and to sensitize health providers to this approach. Thus, an appropriate diagnostic strategy should allow to reduce the delay in the diagnosis, so frequently blamed, and to identify other associated painful diseases. Also, management should be improved as well, not only by applying appropriate therapeutic recommandations, and alternative measures, but also by a better multidisciplinary support towards patient expectations with long-term guidance.

Extended versus involved fields irradiation combined with MOPP chemotherapy in early clinical stages of Hodgkin's disease.

From 1976 to 1981, 335 patients with untreated Hodgkin's disease, clinical stages I, II, and IIIA, have been treated by MOPP (nitrogen mustard, vincristine, procarbazine, prednisone) chemotherapy, three to six cycles according to the prognostic factors, combined with radiotherapy. Irradiation was always performed after the first three cycles of chemotherapy, and was randomized between extensive radiotherapy, ie, mantle and paraaortic areas for supradiaphragmatic presentations, and radiotherapy restricted to the involved areas. No significant difference was observed between the two randomized branches for the disease-free survival (86% after six years in the involved field branch v 90% in the extended field branch), and none for the overall survival. Most of the relapses occurred in nonirradiated areas in the first group, and in irradiated areas in the second. Relapses were especially frequent in the IIE stages with pulmonary extension; extranodal relapses occurred with osseous and cutaneous localizations. Two cases of secondary leukemia were observed after three- or six-cycle MOPP plus radiotherapy limited to the involved areas.

[Women with endometriosis: are they different from others?]. / La femme endométriosique est-elle différente?

The objective of this short review is to identify the particularities of women with endometriosis, especially those complaining of pain and with the most severe lesions. Genetic aberrations play, with a high probability, a major role in the development of this disease, its severity, its tendency to recur and also in its capacity to degenerate. The abnormalities of the endometrium, with exacerbated biological activities, are an example. The woman with endometriosis seems more sensitive to pain through various mechanisms, such as central hypersensitivity and decrease threshold to somatoceptive pain and several associated psychological disorders. Endometriosis is often associated with other painful conditions such as irritable bowel syndrome, interstitial cystitis and fibromyalgia. Finally, also appears also to have a higher risk to develop non Hodgkin's lymphoma or ovarian cancer. These particularities, some of them being still speculative or controversial, should be known in routine practise, in order to offer a better multidisciplinary management, not only for short term, but also long term issues.

[Ovarian endometrioma and infertility: when not to treat?]. / Endométriome ovarien associé à une infertilité: quelle est la place de l'abstention thérapeutique?

Ovarian endometrioma is not infrequently encountered in infertile patients. Its etiopathogeny, its relations with attributed symptoms and the recommanded treatment to apply, are still debated. Various therapeutic tools are available, such as abstention, ultrasonographically guided aspiration and drainage, and surgery. Each option carries specific advantages and disadvantages. Ultrasonographically guided aspiration bears infectious risks. Among various proposed surgical procedures, cystectomy appears to offer the best performances. Results of IVF are slightly or not altered, neither by an ovarian endometrioma, nor by previous surgery, except in case of iterative surgery or if operated lesions were very severe. Laparoscopic surgery is still the first line treatment in many cases. Abstention can be applied in particular circumstances. Ultrasonographically guided aspiration needs to be further evaluated.

[Diaphragmatic hernia in a rare complication of oesophagectomy for cancer]. / Caractéristiques des hernies diaphragmatiques après oesophagectomie pour cancer.

INTRODUCTION: Diaphragmatic hernia is a rare complication of oesophagectomy for cancer. We report a series of seven patients to determine characteristics of this entity. PATIENTS AND METHODS: Seven patients (six male and one female, 61 to 68 years old) were operated on for diaphragmatic hernia following oesophagectomy for carcinoma (adenocarcinoma N =4, squamous-cell carcinoma N =3). Oesophagectomy had been performed through abdominal transhiatal approach in four patients and transthoracically in three, with hiatal enlargement in all cases. RESULTS: Three patients, all symptomatic, underwent emergency surgery within two years following oesophagectomy. Of the four patients operated between two and seven years after oesophagectomy, two were symptomatic. Presence of symptoms were neither related with technique of oesophagectomy, nor to type of hiatal enlargement (anterior, or by crura division). All patients with hernia containing small bowel were symptomatic. All patients were operated through abdominal approach. Hernia contained colon three times, small bowel once, and both three times. Hernia reduction needed additional phrenotomy in six patients. Two patients underwent colectomy to treat peroperative colonic ischemia. Diaphragmatic hiatus was calibrated around the gastric tube by direct suture in six patients or with absorbable mesh in one. There was no death. No recurrences occurred with a follow up ranging from one to five years. CONCLUSION: The diaphragmatic hernia after oesophagectomy is due to excessive hiatal enlargement. Hernias occurring early after oesophagectomy are badly tolerated and need urgent reoperation. To prevent this complication of oesophagectomy, we advocate calibration of diaphragmatic hiatus fit to width of gastroplasty.

Combination of ABVD and radiotherapy in early stages of Hodgkin's disease: analysis of a series of 94 patients. Pierre and Marie Curie Group (GPMC).

In order to reduce, if not completely suppress, late complications of combined chemotherapy and radiotherapy in Hodgkin's disease (HD), MOPP regimen (mechlorethamine, vincristine, procarbazine and prednisone) was replaced by ABVD (doxorubicin, bleomycin, vinblastine and dacarbazine). Ninety-four patients with HD clinical stages I to IIIA with no staging laparotomy were treated by three courses of ABVD followed by radiotherapy. Irradiation was performed on extended fields in 41 cases and on involved fields in 53 others. Consolidation chemotherapy was planned in 67 cases with at least one unfavorable prognostic factor, but achieved only in 33 cases. Seventeen patients relapsed within 1 to 46 months after the beginning of treatment. Ten patients died, 7 of HD and 3 of intercurrent diseases or accident. Disease-free survival rate with a median follow-up of 60 months is 80%. This study showed, on the one hand, many digestive and general side-effects after ABVD and, on the other, a satisfactory hematological tolerance. Furthermore, mediastinitis or cardiovascular complications were not more frequent than with MOPP. These results point out the development and use of better tolerated regimens for initial chemotherapy in HD, without jeopardizing the good results of the treatment.

Hematologic and cytogenetic study of two cases of acute leukemia associated with breast cancer.

The authors present two cases of patients with breast cancer with lymph node extension and who both had surgery. As a pancytopenia with hypercellular bone marrow was discovered at the same time in the first patient, she received no complementary treatment; 4 months later, she presented with an acute lymphocytic leukemia (ALL) for which a remission was easily induced, but she died of a pulmonary infection. The second patient received local radiotherapy (50 grays) and adjuvant chemotherapy (Alkeran for 26 months). Forty-seven months after the diagnosis of breast cancer and 16 months after the end of the treatment, an acute nonlymphoblastic leukemia (ANLL; M6) was diagnosed after 8 months of a preleukemic state. Treatment did not produce any results and death occurred on the 17th day. Cytogenetic studies on the bone marrow cells of both patients were performed. In the first patient in the ALL phase normal cells coexisted with a 47 chromosome clone, the extra chromosome being a D (+ 13?). In the second patient, several karyotype abnormalities were already present in the preleukemic state and also during the acute leukemic phase. No normal mitoses were found; hypodiploidy was present as well as major abnormalities such as markers, rings, and, among others, the systematic loss of a #5 and a #7. The first patient seems to have presented with a de novo ALL, associated with the malignant tumor; whereas, the second patient showed all the characteristics of an induced ANLL. The clinical, hematologic, and cytogenetic characteristics of these two patients are analyzed and compared to those of other cases in the literature.

Refractory anemia with excess of blasts in transformation. Clinical, hematologic, and cytogenetic findings in nine patients.

Clinical, hematologic, and cytogenetic data of nine patients with refractory anemia with excess of blasts in transformation (RAEB-t), classified according to the French-American-British Cooperative Group for myelodysplastic syndrome (MDS), are reported. At diagnosis, eight out of nine cases, had chromosomal abnormalities and three out of nine developed acute leukemia. Karyotype studies allowed individualization of two groups of patients: five with nonrandom major karyotype abnormalities (MAKA) including hypodiploidy, chromosomes 5 and 7 involvement, at least four other abnormalities, and a poor prognosis (survival always under 3.5 months); and four patients with either normal karyotypes or minor karyotype abnormalities (MIKA) (no more than three abnormalities) and a better prognosis (survival from 14 to 38 months). Karyotype appears to be a major prognostic factor among RAEB-t.

Translocation 1;7 in preleukemic states.

A translocation t(1;7) interpreted as t(1;7)(p11;p11) was first reported by Scheres et al. in eight patients with various hematologic disorders. The karyotype of the abnormal cells was trisomic for 1q and monosomic for 7q. Those investigators reported having found four other cases in the literature. We report herein studies of two patients with the same t(1;7).

Cytogenetic studies in twelve patients with primary myelofibrosis and myeloid metaplasia.

Chromosome studies on bone marrow and/or peripheral blood cells without phytohemagglutinin were performed on 12 patients with primary myelofibrosis with myeloid meta-plasia (PMMM) between 1980 and 1984. Abnormal clones were found in six patients (50%). In five cases the abnormal clone involved the long arm of chromosome #7, two of which also had partial trisomy of chromosome #1 and trisomy of 9. Additional abnormalities involving chromosomes #3, #5, #11, #13, #15, and #21 were each found once. Review of the literature showed few studies on the cytogenetics of PMMM. No specific chromosomal pattern can be established; however, abnormalities described are nonrandom.

Role of microlaparoscopy in the diagnosis of peritoneal and visceral adhesions and in the prevention of bowel injury associated with blind trocar insertion.

OBJECTIVE: To determine the frequency of peritoneal and visceral adhesions to the umbilical region according to past surgical history and to estimate the risk of bowel injury with blind insertion of the principal trocar-cannula. DESIGN: Prospective, unicentric study by a single operator. SETTING: Clinique Saint-Sernin and Polyclinique de Bordeaux, Bordeaux, France. PATIENT(S): Eight hundred fourteen patients undergoing diagnostic or operative laparoscopy were classified into four groups based on their history of abdominal surgery: group I (n = 469), no previous abdominal surgery; group II (n = 125), prior laparoscopic surgery; group III (n = 131), previous laparotomy with a horizontal supra-pubic incision; group IV (n = 89), previous laparotomy with a midline incision. INTERVENTION(S): Initial microlaparoscopy performed through the left upper quadrant of the abdomen, inspection of the anterior abdominal wall and particularly the umbilical area for the presence of adhesions. Patients who had adhesions were assessed as to whether or not they were at significant risk of injury from blind insertion of the principal trocar. MAIN OUTCOME MEASURE(S): Incidence of umbilical adhesions and the potential risk of bowel injury with blind insertion of the umbilical (principal) trocar. RESULT(S): Umbilical adhesions were found in 9.82% of the 814 cases. The rates of umbilical adhesions were as follows: group I, 0.68%; group II, 1.6%; group III, 19.8%; and group IV, 51.7%. Severe adhesions with potential risk of bowel injury with blind insertion of the umbilical trocar in the four groups were 0.42%, 0.80%, 6.87%, and 31.46%, respectively. CONCLUSION(S): Women with previous laparotomy have a higher incidence of umbilical adhesions, especially in case of midline incision. Preliminary inspection of the umbilical area with a microlaparoscope and insertion of the umbilical trocar under direct vision are recommended for patients at risk for adhesions to reduce complications associated with insertion of the principal (umbilical) trocar.

Female fertility and donor insemination.

Artificial insemination with donor semen (AID) frozen in 0.25-ml straws yielded an overall pregnancy rate of 64% in a series of 131 patients. The pregnancy rate was significantly higher in patients whose husbands were azoospermic (70%) than in women whose husbands were severely subfertile (48.8%) (P less than 0.02). Equivalent ages of patients as well as donor distribution between both groups were confirmed. This study brings evidence that patients turning to AID because of severe male subfertility represent a selected hypofertile population, from which the highly fertile females have disappeared through previous spontaneous conception.

Coculture of embryos on homologous endometrial cells in patients with repeated failures of implantation.

OBJECTIVE: To evaluate the value of coculture of embryos on endometrial cells in patients with repeated failures of implantation. DESIGN: A retrospective comparison of pregnancy rates between IVF-ET with coculture and standard culture methods. PATIENTS: Ninety patients with repeated failures of transfer (range 4 to 11) underwent IVF-ET for a variety of disorders. METHOD: Embryos were cocultured on homologous endometrial cells and transferred on day 4 after retrieval of oocytes. RESULTS: The overall pregnancy rate for these patients was 21% per transfer versus 8% in previous IVF-ET cycles. A higher percentage (28%) was obtained for women < 39 years of age or on transfer of at least one morula (32.5% pregnancy per transfer). CONCLUSION: Coculture of embryos on homologous endometrial cells is both safe and ethical. It appears to be a valuable approach for the selection of a good quality embryo before transfer. The technique should prove to be of benefit to patients with repeated failures of implantation and also may be of value for assessing the respective responsibility of endometrium and embryo in these repeated failures. However, the mechanisms underlying this improvement need to be determined to simplify the procedure.

Pre or post-operative medical treatment with nafarelin in stage III-IV endometriosis: a French multicenter study.

OBJECTIVES: To determine the effectiveness of a 6-month course of nafarelin in the treatment of stage III-IV endometriosis and to determine if pre-operative use of nafarelin facilitates surgery. DESIGN: Prospective, multicenter, clinical trial. SETTING: Eight university hospitals and two private practice institutions in France. PATIENTS: Fifty-five patients with stage III and IV endometriosis. Two were excluded. INTERVENTIONS: The severity of endometriosis was assessed at the time of laparoscopy and patients were randomized to have either laparosopic surgery at that time following 6 months of nafarelin therapy (n=28), or laparoscopic surgery following 6 months of nafarelin therapy (n=25). All had 200 microg intranasal nafarelin twice a day for 6 months and a second look laparoscopy. MAIN OUTCOME MEASURE: Clinical efficacy, tolerance to the treatment. RESULTS: Efficacy and tolerance to the treatment were the same in both groups. AFS scores compared on both laparoscopies were significantly better if nafarelin was given prior to surgery (P=0.007). CONCLUSIONS: This preliminary study shows that in cases of combined medico-surgical treatment for stage III-IV endometriosis, preoperative medical treatment with GnRH-a gives a better AFS score improvement, but no conclusion was possible whether preoperative treatment facilitates surgery.

Poststerilization pain: a comparison of band versus clip.

PIP: The question of whether clip vs. ring tubal occlusion is more painful postoperatively was examined in this small prospective study. In cases requesting occlusion tubal sterilization, 1 tube was occluded by a Falope ring and 1 was closed by a Hulka clip in a randomized fashion. Patients graded location and degree of pain postsurgically. In 95 patients analyzed, rings were applied on the right in 45 cases and on the left in 50, and clips were applied on the left in 45 cases and on the right in 50. 48-hours postsurgery, pain was reported by 41% of patients (n=39). In 18 of these, the pain was diffused; in 21 the pain was unilateral. Pain was noted more on the right than on the left side. There was no difference between the clip and ring with respect to initiation or causation of poststerilization pain, rather, it seems that in general, regardless of occlusion or surgical method chosen, pain poststerilization is more frequent on the right than on the left side.^ieng
