Use of optical catheters for diagnostic office laparoscopy.

OBJECTIVE: To evaluate several small optical catheters (1.8-mm outer diameter) developed to allow access to the pelvic cavity for laparoscopic diagnosis in the operating room and in an office setting. STUDY DESIGN: Thirty-six procedures are reported, 20 performed in the operating room so that proper placement could be monitored and ensured, and the findings were compared with those obtained with a standard, 10-mm laparoscope. The remaining 16 procedures were performed in an office setting. The patients were women who were candidates for second-look laparoscopy, had pelvic pain and no physical findings, or were evaluated for possible tubal anastomosis. CONCLUSION: The small, rigid catheter, with its excellent optics, provided a clear view of the pelvis without the need for general anesthesia and associated costs. The procedure was performed easily and successfully with a local anesthetic and with minimal discomfort for the patient.

A new valving system for removal of laser plume during pelvic CO2 laser endoscopic procedures.

The large volumes of laser plume and char created during carbon dioxide laser endoscopy of the pelvis present a common problem to the gynecologic surgeon. Laser plume not only interferes with the view of the surgical field but also reduces the efficiency of emitted laser energy. A valving system has been designed and clinically tested that allows easy removal of laser-created debris while simultaneously maintaining control of the pneumoperitoneum. The system also removes these gas and liquid products without contaminating the operating room environment or hospital vacuum handling systems.

Laser laparoscopy. A new modality.

Assuming that a surgeon could have a laser available during every laparoscopic procedure, two pertinent questions would need to be addressed. First, how often can, or should, one use the laser laparoscope? Second, what are its advantages over the conventional techniques of operative laparoscopy? These and several other, related questions were answered partially by a study of pregnancy rates after vaporization and adhesiolysis with laser laparoscopy in cases of stage I and II endometriosis.

Relationship between the results of sperm analysis and GIFT.

In vitro fertilization (IVF) and GIFT have been proposed as therapeutic approaches in infertile couples where a significant male factor is present. To date, few published data are available relating the success rate of GIFT to the severity of the male factor. In this report the results of the first 172 GIFT cases were analyzed. The overall pregnancy rate was 18.0%. The relationship between the occurrence of pregnancy and sperm count (millions/ml), total sperm count (millions/ejaculate), % motility, motile sperm count (millions/ml) and total motile sperm count (millions/ejaculate) were examined. Significant direct correlations were observed between the clinical pregnancy rate and sperm count, total sperm count, motile sperm count and total motile sperm count. Motile sperm count and total motile sperm count had the best correlations with clinical pregnancy rates, which were over 24.0% in groups with motile sperm counts exceeding 40 X 10(6) cells/ml or total motile sperm counts greater than 100 X 10(6)/ejaculate. The clinical pregnancy rates were 12.5% and 7.7%, respectively, for groups with motile sperm counts under 10 X 10(6)/ml and total motile sperm counts below 25 X 10(6)/ejaculate. No correlation was found between percent motile cells and pregnancy rate. Results of the sperm penetration assay using zona-free hamster eggs were available in a subpopulation of 27 patients. No significant correlation between this sperm penetration assay and pregnancy rate could be demonstrated. The incidence of chemical pregnancy showed a significant negative correlation with the total motile sperm count, indicating a higher incidence of early pregnancy wastage in cases of oligozoospermia.(ABSTRACT TRUNCATED AT 250 WORDS)
