Fimbrial ciliated cells percentage and epithelial height during and after salpingitis.

Microbiopsies of 191 fimbriae were obtained from 146 patients undergoing laparotomy for acute salpingitis, or tubal surgery after salpingitis. The biopsies were classified in four groups according to the diagnosis at laparotomy: salpingitis, distal occlusion, peritubal adhesions or tuberculosis. The biopsies belonging to the group of distal occlusion were further classified in four sub-groups according to the extent of the lesions observed during the hysterosalpingography and laparoscopy. Since the crucial role of the ciliated epithelium in the ovum transport has been established, the percentage of ciliated cells and the epithelial height were determined in the groups and compared to those observed in fimbriae obtained from fertile women during an ovulatory cycle. Significant differences were noted in all groups when compared to fertile women. Acute salpingitis provoked a rapid and severe deciliation which recovered 3 months after triantibiotherapy. In the groups of distal occlusion, there was a significant correlation between the rate of deciliation and the extent of lesions. This suggests that deciliation of tubal epithelium is a sequela of salpingitis and that the extent of disease allows a prognosis of the percentage of ciliated cells.

Tubal polyps, epithelial inclusions, and endometriosis after tubal sterilization.

Histologic findings in 133 previously ligated fallopian tubes of women who underwent subsequent hysterectomy and bilateral salpingectomy were compared with those of 50 normal fallopian tubes and related to four surgical procedures for sterilization. Dilatation of proximal tubal lumen, flattening of the folds, polyps, and increase of mitotic activity of the epithelium was subsequent to tubal occlusion in any case, regardless of the type of sterilization. After sterilization by ring, ligation, and coagulation, the incidence of epithelial inclusions was significantly different from that observed after sterilization by clips. Focal endometriosis was only found after tubal ligation and coagulation. It is suggested that epithelial inclusions were the result of surviving fragments of tubal epithelium translocated in the tubal wall during the procedure, and that endometriosis was caused by implantation of expelled menstrual products through the open lumen into the healed ligation area.

Changes in ciliation and cell height in human tubal epithelium in the fertile and post-fertile years.

A total of 162 fallopian tubes was obtained from a sample of subjects comprising fertile women with regular ovulatory cycles, post-menopausal women taking no hormonal drugs and post-menopausal women receiving oestrogen therapy in various forms. During the menstrual cycle the highest percentage of ciliated cells was found, in all of the three tubal portions studied, around ovulation time. The epithelial height decreased significantly subsequent to ovulation. After more than 1 yr had elapsed following the menopause, the percentage of ciliated cells and epithelial height decreased significantly. Very low values were observed in women 10 yr after the menopause. In women receiving oestrogen therapy for more than 10 yr following the onset of menopause - conjugated equine oestrogens (CEE), 1.25 mg/day - the percentage of ciliated cells was significantly higher than that in subjects not receiving hormonal therapy. Similar data were obtained in the case of women taking oestriol (2 mg/day). The data presented demonstrate that oestrogen therapy influences the ciliation and height of oviductal epithelium.

[Microscopic study of human fallopian tubes after laparoscopic sterilization (author's transl)].

Histological study was carried out on human fallopian tubes one hour and one month after various methods of laparoscopic sterilization (unipolar electrocoagulation, bipolar electrocoagulation, silicone ring and Hulka-Clemens clip). Microscopic lesions were observed. Ciliated cells were counted. Deciliation is proved at a distance from the site of sterilization. It has been possible to display the substance loss of the tubal tissues which have to be taken into consideration in case of surgical reanastomosis.

Macroscopic and microscopic studies of fallopian tube after laparoscopic sterilization.

Histological study was carried out on human fallopian tubes one hour and one month after various methods of laparoscopic sterilization. Ciliated cells were counted and histological lesions were observed. Deciliation is proved at a distance from the site of sterilization. Taking into account these two data, it has been possible to display the substance loss provoked by each of the usual sterilization methods (unipolar electro-coagulation, bipolar electrocoagulation, silicone ring and Hulka-Clements clip) which have to be taken into consideration in case of surgical re-anastomosis.

Endometriosis-associated infertility: evaluation of preoperative use of danazol, gestrinone, and buserelin.

In order to assess adequately the effectiveness of danazol, Gestrinone, and Buserelin, a prospective nonrandomized study was initiated in 126 patients with laparoscopically confirmed ovarian endometriosis. After hormonal therapy, laparotomy with microsurgical resection of endometriotic cysts was carried out. Regression (greater than 25%) of ovarian endometriosis was noted in 30%, 34%, and 73% of cases after danazol, Gestrinone, and Buserelin, respectively. The pregnancy rate in moderate endometriosis (53%) differed significantly from the rate obtained in severe endometriosis (45%). The highest percentages were found after Buserelin therapy. In conclusion, Buserelin emerged superior to danazol or Gestrinone treatment. Nevertheless, hormonal treatment leads to an incomplete suppression of ovarian endometriotic implants and this suggests the necessity of surgically removing invasive ovarian endometriosis.

Surgical management of tubal obstruction at the uterotubal junction.

The advantages of microsurgical anastomosis for cornual occlusion are evaluated in a series of 82 pure cases of pathologic cornual occlusion. The term pregnancy rate was 44% and the ectopic pregnancy rate was 7%. The following factors were found influencing the pregnancy rate: maximized tubal length; preserved intramural portion; absence of chronic inflammation; absence of tubal inclusions; absence of tubal endometriosis.

Morphologic study of mechanically induced hydrosalpinges in rabbits.

Ligation of the proximal and distal ends of the rabbit oviduct was used to induce hydrosalpinges, which shows a remarkable resemblance, both macroscopically and microscopically, to human hydrosalpinges. Isthmic and ampullary biopsies obtained at varying intervals were examined with light microscopy. Progressive deciliation and decrease of epithelial and mucosal fold height were observed in the ampulla, but not in the isthmus. Microstereological study shows progressive reduction of both the number and the relative volume of capillaries in the ampulla. Considering the parallelism of time and localization, it is suggested that epithelial deciliation is caused by vascular disorders.
