Neosalpingostomy for distal tubal obstruction: prognostic factors and impact of surgical technique.

We reviewed the clinical records of all women who underwent microsurgical terminal neosalpingostomy for distal tubal obstruction between January 1983 and June 1988. We identified 95 women whose preoperative evaluation revealed no other contributory factors for infertility and analyzed their pregnancy outcome after this procedure. Pregnancy success was inversely related to the extent of tubal distortion (dilation, rugal integrity, and status of the fimbria) and degree of adnexal adhesions. Using our classification system for distal tubal obstruction, patients with mild disease had an 80% pregnancy rate, whereas patients with moderate and severe disease had a 31% and 16% success rate, respectively. We found no statistically significant difference in pregnancy outcome when we compared this series with our previous group, reported in 1978, where contemporary microsurgical technique was not used. Although we feel that optimal surgical technique is important to maximize success, we conclude that the most important prognostic factor in pregnancy outcome after neosalpingostomy for distal tubal disease is the anatomical and functional integrity of the tube.

Chlamydial genital infections and laparoscopic findings in infertile women.

Several studies have shown that previous chlamydial genital infection, reflected by serological markers, is strongly associated with tubal damage leading to tubal infertility. In 105 women undergoing laparoscopy, multiple samples were collected from the lower (urethra and cervix) and upper (endometrium, peritoneal fluid, tubal lumen) genital tract, in order to isolate Chlamydia trachomatis in cell culture. Chlamydia trachomatis was isolated from at least one site in 13 (30.9%) of 42 infertile women with tubal infertility, in 5 (12.1%) of 41 women with unexplained infertility, in 1 of 4 women affected by acute salpingitis and in 1 (5.5%) of 18 women with endometriosis or uterine malformations. The latter group was the control group. Thirteen (65%) of the 20 positive women harboured Chlamydia trachomatis in their upper genital tract alone and 16 women were positive in one or both tubes. Only one of the positive women showed laparoscopic signs of acute pelvic infection. Four of the 5 positive women with unexplained infertility harboured Chlamydia trachomatis in the tubal lumen. This study confirms that chlamydial infection is strongly associated with tubal damage. It suggests that cervical cultures are inadequate for excluding a tubal infection and that chlamydial colonization of the tubal mucosa is possible in the absence of symptoms and laparoscopic signs of active infection.

Pathologic findings in the oviducts of mares.

Oviducts from 325 mares were evaluated macroscopically, and oviducts from 124 mares were evaluated microscopically. Two hundred and eighty-five (87.69%) of the mares had at least 1 macroscopic lesion and 116 (93.54%) had at least 1 microscopic lesion. The most frequently seen macroscopic lesions were adhesions, paraovarian cysts, and thick fibrous bands. Microscopically, intraepithelial cysts, slight, focal lymphocytic infiltration in the infundibular-ampullary region, and proteinoid material in the oviductal lumen were the most common findings. In general, the proximal segments of the oviduct were more affected than were the distal segments. Forty-nine (90.74%) of the 54 pairs of oviducts collected from pregnant mares had at least 1 macroscopic or microscopic lesion.

Microsurgery in gynecology.

Microsurgical techniques have changed the outcome of infertility surgery. Tubal anastomosis for reversal of sterilization has resulted in pregnancy rates of up to 65%. In cases of salpingostomy, the ectopic pregnancy rate is quite high. In ovarian microsurgery, postoperative adhesions can be avoided and a 54% pregnancy rate achieved with endometriosis surgery.
