[Intra-tubal embryo transfer (IVF/IT-ET) in the treatment of non-tubal-induced sterility. Initial studies of the value of a new and expensive therapy procedure].

Intratubar embryo transfer is a form of sterility treatment, in which the in-vitro-fertilized pre-implantation embryos are transferred into the intact fallopian tube(s). This enables the benefits of in-vitro fertilization (information of the gamete fertilization behavior, specific incubation of dysmature oocytes, reduction of the polyploidy rate, risk of multiple pregnancies) to be combined with those of gamete intrafallopian transfer (GIFT; tubar environment for the further development of the pre-implantation embryos). Intratubar embryo transfer is indicated in cases of sterility that are not due to the fallopian tubes; in addition to idiopathic sterility, particular emphasis is put on a certain form of immunological sterility (antibodies against sperm antigens), which seems to be a special indication for this method. Intratubar embryo transfer demands a two sided approach. It is advisable to collect the oocytes transvaginally, guided by ultrasound, since general anaesthesia maybe dispensed with - if so desired. The embryo transfer itself still requires a pelviscopy, which is only performed once fertilization of the oocyte has been confirmed; which is in contrast to GIFT, in which pelviscopy is an inherent part of each treatment cycle. In spite of this advantage, intratubar embryo transfer is a method, which is associated with a high expenditure. The aim of the study was, to evaluate the success rate when all the alternative, less costly options have been exhausted. Our first results are demonstrating, that intratubar embryo transfer is successful, even as a second line therapy. Therefore the method has a significance in the treatment of sterility, not caused by the tubes and the expenditure, with which it is associated, can be justified.(ABSTRACT TRUNCATED AT 250 WORDS)

[Fertility following function-preserving surgery in tubal pregnancy].

In the last few years an obvious trend toward conservative technique in tubal surgery is observed. Likewise, at our institution, emphasis was placed on preservation of function, too. 59 patients received conservative surgery of tubal pregnancies between 1979 to 1982. 7 women were lost for follow-up. 28 patients showed further desire for child-bearing. 20 of them have had a subsequent intrauterine conception (71.4%), 11 women have had term pregnancies (39.3%). 3 patients were pregnant at time of investigation. The abortion rate was 17.8%. Recurrent ectopic pregnancies were found in 5 cases (9.5%). However, the operated fallopian tube was involved only in 3 cases (5.7%). In 26 cases the patency of the tubal lumen was examined by means of hysterosalpingography. 50% of those women had remained childless. The results of HSG showed a patent passage of the operated tube in 11 cases. Our results show a high rate of subsequent pregnancies and a rather low incidence of repeat ectopic pregnancies in cases of conservative surgery and justify our decision to save the involved tube whenever fertility is desired.

Falloposcopic observations of endotubal isthmic plugs as a cause of reversible obstruction and their histological characterization.

Eighty falloposcopies were performed in fallopian tubes of women with suspected tubal disease. In three falloposcopies (4%), isthmic plugs were observed occluding the entire isthmic lumen. In all cases these plugs were mobilized by falloposcopic-directed, selected tubal cannulation and aquadissection techniques. Restoration of tubal patency, verified by concurrent chromopertubation under laparoscopic monitoring was achieved in all cases. On one occasion, the isthmic plug was mobilized and identified on the fimbria, and tubal patency was confirmed. When this plug was retrieved and examined histologically, it was found to consist of a cast of debris containing aggregates of histiocyticlike cells of endometrial stromal or mesothelial origin. The genesis of these plugs is unknown. In another subgroup, white to yellow mucus like fragments were observed within the intramural and isthmic lumen during a further 8 of 80 falloposcopies (10%). Whether these mucus like fragments are of physiological or pathophysiological significance remains to be determined. Objective demonstration that isthmic plugs can cause reversible proximal tubal obstruction (PTO) has been achieved using falloposcopy. Falloposcopy offers the diagnostician the ability to objectively classify the cause of PTO. A useful falloposcopic classification and scoring system of tubal lumen lesions has been utilized and is described.

Hysterosalpingo contrast sonography (HyCoSy) with SH U 454 (Echovist) for the assessment of tubal patency.

A total of 88 Fallopian tubes from 44 patients was examined with hysterosalpingo contrast sonography (HyCoSy), hysterosalpingogram (HSG), and laparoscopic chromopertubation (LC) in order to assess their relative accuracy for measuring tubal patency. HyCoSy was done by transvaginal ultrasound and the contrast was SH U 454 (Echovist). The flow of multiple fractions of the contrast medium through each Fallopian tube was observed in real time in appropriate imaging planes by means of a transvaginal probe. Compared with laparoscopic results, we found a sensitivity of 85.2%, a specificity of 85.2%, a positive predictive value (PPV) of 71.9%, a negative predictive value (NPV) of 92.9% and concordance (HyCoSy/LC) of 85.2%, while the corresponding values for HSG were sensitivity = 85.2%, specificity = 83.6%, PPV = 69.7%, NPV = 92.7% and concordance (HSG/LC) of 84.1%. Compared with HSG results, HyCoSy obtained a co-positivity of 66.7%, a co-negativity of 81.8% and a concordance of 76.1%. In conclusion, HyCoSy with SH U 454 proved to be a reliable and safe modality for evaluating tubal patency; it is suitable as an outpatient diagnostic procedure to be used before more invasive procedures.

Three-dimensional dynamic MR-hysterosalpingography; a new, low invasive, radiation-free and less painful radiological approach to female infertility.

BACKGROUND: The purpose of this study was to propose a new method for imaging the uterine cavity and Fallopian tube patency by three-dimensional dynamic magnetic resonance hysterosalpingography (3D dMR-HSG) and to analyse if, by using a higher viscosity contrast solution, direct visualization of the Fallopian tubes may be achieved by this new technique. METHODS: 10 consecutive infertile women underwent 3D dMR-HSG and conventional HSG as gold standard. 3D dMR-HSG consisted of injection of 20 ml of a gadolinium-polyvidone solution into the uterine cavity while acquiring five consecutive three-dimensional (3D) T1-weighted MR-sequences. RESULTS: In three patients the catheter became dislodged during 3D dMR-HSG. However, in one of these patients the examination was still partially diagnostic. Imaging findings of 3D dMR-HSG showed good correlation with conventional hysterosalpingography and allowed 3D imaging of the uterine cavity and of Fallopian tube patency in 8/10 patients and direct visualization of the Fallopian tubes in 5/7 patients. CONCLUSION: 3D dMR-HSG represents a new and promising imaging approach to female infertility causing less pain and avoiding exposure of the ovaries to ionizing radiation. By using a higher viscosity MR-contrast agent it allows not only visualization of uterine cavity and Fallopian tube patency but also direct visualization of Fallopian tubes.

Successful conception following Fallopian tube recanalization in infertile patients with a unilateral proximally occluded tube and a contralateral patent tube.

BACKGROUND: There are many published case reports of successful conception following transcervical Fallopian tube recanalization (T-FTR) in patients with bilateral proximally occluded Fallopian tubes. However, no serial trials have been published with respect to successful conception following unilateral tubal recanalization in infertile patients with a unilateral proximally occluded tube and a contralateral patent tube. This study was designated to analyse the success rate of T-FTR and the pregnancy rate due to natural fertilization in the lumen of the recanalized tube in these patients. METHODS: We have encountered only 11 patients with this abnormality in our department in the past 10 years. T-FTR with fluoroscopic guidance was performed in these patients, confirmed by at least two hysterosalpingographies to exclude tubal spasm. The uterine catheter devised by us was used during the procedure. RESULTS: All 11 Fallopian tubes were successfully opened by T-FTR. In the six patients who conceived, a preovulatory follicle was demonstrated on the side of the cannulated tube during the conception. The success rate of recanalization, the pregnancy rate due to fertilization in the lumen of the recanalized tube and the successful delivery rate were 100, 55 and 36% respectively. CONCLUSIONS: Our findings suggest that a functional and/or organic disorder in the patent tube resulted in infertility in patients with unilateral proximal tubal obstruction. Our results further show that recanalization of occluded tubes is an effective treatment. Thus, recognition of successful conception following T-FTR in these patients will be beneficial to our clinical approach to this infertile condition.

The assessment of tubal functional status by tubal perfusion pressure measurements.

The measurement of tubal perfusion pressures (TPP) is a recent advance in the field of gynaecoradiology. Measurement of TPP involves a standardized technique using transcervically placed tubal catheters which is reviewed in detail. TPP assesses the functional status of the Fallopian tubes, i.e. their ability to permit pregnancy. Infertile patients with normal TPP demonstrated a higher pregnancy rate (10 out of 23) than patients with elevated TPP (four out of 24, P < 0.05). Analysis of patients who had undergone a laparoscopy as well as measurement of TPP suggest that elevated TPP are highly indicative of tubal endometriosis. Tubal catheterization with wireguides was successful in reducing mildly elevated TPP. The impact of this procedure on pregnancy rates is not known. The use of the gynaecoradiological techniques discussed in this paper has reduced the need for diagnostic laparoscopy at our centre by >60%. This was achieved without compromise in pregnancy rates and has resulted in a considerable reduction in cost.

Distal tubal obstruction induced by repeated Chlamydia trachomatis salpingeal infections in pig-tailed macaques.

The effects of repeated infections with Chlamydia trachomatis, serovars F, D, and J, were examined in pig-tailed macaques. The fallopian tubes of three experimental monkeys were inoculated at the middle of the menstrual cycle on three consecutive months. Monkey 1 received homologous F; monkey 2 received heterologous F, D, and J; and monkey 3 received homologous inoculations in the right and heterologous inoculations in the left fallopian tubes. One control monkey (4) received repeated inoculations of HeLa cell materials only and remained normal throughout the experiment. Infection was confirmed by isolating the microorganism from both the endosalpinx and endocervix. Antibody to the infecting strains was demonstrated in sera, tears, and cervical secretions by using microimmunofluorescence. Mild chronic salpingitis developed in monkeys 1 and 3, and chronic follicular salpingitis developed in monkey 2. Peritubal and periadnexal scarring and endosalpingeal adhesion formation were produced after reinfection. The right fallopian tube of monkey 3 was distally obstructed (confirmed by hysterosalpingography). Systemic complications, including perihepatitis and conjunctivitis, were also documented in these monkeys. We conclude that repeated infections produced extensive tubal scarring, chronic salpingitis, and distal tubal obstruction, findings not apparent in primary infection.

Falloposcopic cannulation, oviductal appearances and prediction of treatment independent intrauterine pregnancy.

The purpose of this study was to determine whether there is an association between the appearance of the oviductal lumen during falloposcopic examination, and the occurrence of intrauterine pregnancy or ectopic pregnancy independent of treatment. Sixty-two consecutive women were recruited who were examined falloposcopically in-office, and who did not require subsequent surgical intervention to restore tubal patency. There was a heterogeneous group of presentations including unilateral and bilateral proximal tubal occlusion, unexplained infertility and the presence of minor laparoscopic abnormalities which might suggest the possibility of occult endotubal pathology. A stepwise Cox's model of life table analysis selected the number of falloposcopically normal and patent Fallopian tubes as the only variable significantly associated with intrauterine pregnancy, when all clinical, demographic and investigative data were analysed. The presence of minor distal intra-tubal adhesions was selected on stepwise analysis as the only variable significantly associated with the occurrence of ectopic pregnancy. A number of falloposcopic abnormalities were significantly associated with outcome in the clinical sub-group who presented with bilateral proximal tubal occlusion. These data suggest that falloposcopy is a valuable clinical tool which provides useful prognostic data for the prediction of intrauterine pregnancy or ectopic pregnancy.

Laparoscopic rescue after tubal anastomosis failure.

Laparoscopic rescue after tubal anastomosis failure is reported for the first time. The patient was a 33 year old woman sterilized by Pomeroy's method. Reconstruction of fertility was achieved by mini-laparotomy with isthmo-isthmic end-to-end anastomosis of bilateral tubes. Unfortunately, the patient did not become pregnant and tubal occlusion was diagnosed 6 months later by hysterosalpingography. Laparoscopic rescue with repeat isthmic-ampullary anastomosis and adhesiolysis was performed. Post-operatively, the patient had one menstruation and then achieved an intrauterine pregnancy. Instead of in-vitro fertilization/embryo transfer, laparoscopic rescue may be an alternative option for the patient with failed anastomosis.

Laparoscopic tubal anastomosis (the one stitch technique): preliminary results.

We report a new laparoscopic technique of tubal anastomosis: the laparoscopic one stitch technique. After preparation and approximation of the two tubal segments, the anastomosis consists of one single suture placed at the '12 o'clock' site of the antimesenteric borders. Four patients have undergone this procedure. Bilateral tubal patency was confirmed in three cases. Hysterosalpingography was not performed on the fourth patient as she was already 1 month pregnant after tubal anastomosis.

Microsurgical reanastomosis of the fallopian tube: increasingly successful outcome for reversal of previous sterilization procedures.

Reanastomosis of the fallopian tube represents a potential means of restoring fertility to women who have previously had sterilization procedures. During a 40-month period from January 1977 to June 1980, 46 such women had ent-to-end reanastomosis at Vanderbilt University Hospital, 59% after a change in their martial status. The surgical procedure included microsurgical technic, with the use of antibiotics, corticosteroids, intraperitoneal dextran, and postoperative hydrotubation. No stents or splints were used. Tubal patency was demonstrated in 43 patients (93%). Pregnancy was achieved in 25 of the 37 patients (68%) properly followed up for one year. There were no ectopic pregnancies. In three patients who did not conceive, a "second-look' laparoscopy revealed the presence of pelvic adhesions. Such a procedure allows a more accurate assessment of both the cause of the continued infertility and the future prognosis.

Determination of velocity of tubar transport with dynamic hysterosalpingoscintigraphy.

Transport of 99mTc labelled albumin macroaggregates (MAA) can be used as a substitute for assessing transport of spermatozoa within the female genital tract. As yet, the velocity of tubar MAA transport has not been systematically studied in a large group. Dynamic hysterosalpingoscintigraphy (HSS) was performed after intrauterine instillation of 10-20 MBq 99mTc-MAA in 88 pre-ovulatory women suffering from infertility. They had to have anatomical patency of both tubes and at least one enlarged follicle. The direction and the latency of transport were evaluated. Forty-four per cent of patients exhibited MAA transport only to the dominant follicle, 31% to both ovaries and 16% to the contralateral ovary. In 9% no transport was visible. Fifty per cent of all patients studied exhibited MAA transport to the dominant follicle within 30 s, 75% within 20 min. Transport velocity in women having bilateral or ipsilateral transport did not differ significantly. There was no significant correlation between the size of the follicle and transport velocity. We conclude that in the majority of cases MAA transport occurs within 30 s after instillation. The variation in transport time between 30 s and 20 min suggests that dynamic scintigraphy is, in principle, better suited to a refined analysis of tubar function than static HSS.

Pulmonary edema following intrauterine methylene blue injection.

Methylene blue is a commonly used dye in diagnostic procedures such as fistula detection, delineation of body tissues during surgery and for checking the patency of fallopian tubes. Many such dyes interfere with accurate measurement of oxygen saturation by a pulse oximeter. We report here a case in which methylene blue hot only interfered with pulse oximetery but also caused pulmonary edema in an ASA grade 1 patient.
