Implantation procedures for intramural obstruction. Pure bilateral implantation in 35 patients.

From 1976 through 1979, 740 women were referred to the author for potential tuboplasty; of these, 435 patients (58.8%) were selected for diagnostic laparoscopy. A tubal repair by laparotomy was performed on 280 patients, and 35 (12%) of them were pure bilateral implantations into the posterior uterine wall. The procedure was successful in 24 patients (68.6%).

The correlation of pelvic ultrasound and laparoscopy in the diagnosis and management of gynecologic disorders.

Cases were reviewed in which both laparoscopy and ultrasound were performed for diagnostic purposes at the Ben Taub General Hospital, Houston, Texas, from January 1976 through May 1977. Thirty patients were found to have undergone both procedures. The most common reason (13 cases) was the presence of an adnexal mass. The findings from both techniques agreed in 20 cases, for a positive correlation of 66.7%. Different diagnoses were found in 10 cases, for a negative correlation of 33.3%. The major cause of the discrepancy was the presence of pelvic adhesive disease, not diagnosed by ultrasound but observed via laparoscopy. When the ultrasound findings were reported as "normal," all were confirmed at laparoscopy. Eight laparotomies were performed, and in each case the laparoscopic findings were confirmed.

Laparoscopic exposure and sequential observation of the ovary of the cycling bitch.

A method was developed to alter surgically the bursa of the bitch to allow sequential observation of the ovary by means of laparoscopy. Adult anesthetized female dogs of three breeds underwent laparoscopic examinations in which each natural bursa slit was lengthened 1.0-1.5 cm using laparoscopic hook scissors in conjunction with electrocautery. The ovary could be effectively and repeatedly exposed for laparoscopic viewing through the lengthened bursa slit. Neither laparoscopic surgery nor frequent routine laparoscopic examinations of the reproductive organs had an effect on subsequent ovarian activity. All dogs subjected to the laparoscopic ovarian exposure technique exhibited estrus behavior, follicle development, ovulation and corpus luteum formation. Preovulatory follicular development was detected as early as 11 days before ovulation with the most rapid follicular maturation occurring two to three days before ovulation. Follicular collapse and extensive hemorrhage at the rupture site during ovulation did not occur. Release of the cumulus mass from a vesicular follicle was observed in one bitch. The cumulative mass adhered to the follicular wall for an indefinite time following ovulation. The structural size of the bitch corpus luteum was maximal four to eight days following ovulation. Corpora lutea remained visible on the ovarian surface for 16 weeks. No differences in cyclic ovarian morphology were observed among the three breeds of dogs studied.

Nonelectric laparoscopic sterilization. Experience with a silastic band.

In an attempt to avoid the serious complications of electrosurgical sterilization via laparoscopy, specially designed applicators have been used to apply a silastic band to the fallopian tube, thereby occluding it. Two hundred and eighty cases have been performed, 70 of which have been followed for more than 1 year. There have been no pregnancies. The technic is relatively simple. Complications result when the tube is excessively thickened, when the tube is fixed in position by adhesion, or when the tube is grasped too close to the cornua or too rapidly. These complications have been relatively few and can be easily avoided.
