Total laparoscopic hysterectomy.

Alternatives to hysterectomy can provide excellent treatment outcomes for many women. In general, these alternatives are underused. For some women, however, alternative treatments fail and hysterectomy provides the best approach. The goal of future research should be to define better this group of women. For women who require hysterectomy, the laparoscopic approach affords the benefit of less postoperative discomfort, shorter hospital stay, and quicker recovery. The surgical techniques and instruments for laparoscopically directed hysterectomy are still in development. Few randomized, prospective studies that involve large numbers of patients have compared the risks and benefits of this approach with standard hysterectomy. In addition, data on the effectiveness of the operation, as performed by large numbers of gynecologists, are still not clear. Although the potential for real benefit exists, it is hoped that further study will clarify the place of laparoscopic-assisted hysterectomy in the nonsurgical and surgical treatment offered to patients.

Laparoscopic-assisted vaginal hysterectomy: American Association of Gynecologic Laparoscopists' 1995 membership survey.

A questionnaire was mailed to all members of the AAGL to determine the current performance of laparoscopic-assisted vaginal hysterectomy (LAVH), and to assess the relative frequencies of techniques and complications. Answers of the 1092 members who responded were entered into a database computer program and analyzed. The analysis revealed 14,911 LAVHs performed by 767 members. Complication rates appeared to be in the same range as those reported for vaginal hysterectomy and total abdominal hysterectomy. Inferior epigastric injury was the most common complication. Physicians showed a shift in their practices away from abdominal hysterectomy after they learned LAVH.

Laparoscopic management of benign cystic teratomas during pregnancy.

OBJECTIVE: Our purpose was to evaluate the surgical management and outcome of laparoscopic removal of benign cystic teratomas during pregnancy. STUDY DESIGN: The records of women with benign cystic teratomas who were managed with operative laparoscopy during pregnancy were reviewed. RESULTS: Twelve women had laparoscopic removal of a benign cystic teratoma during pregnancy. Gestational ages at surgery ranged from 9 to 17 weeks, with a mean of 14 weeks. Cyst size ranged from 5 to 13 cm, with a mean of 8.5 cm. Intraoperative rupture of the cyst occurred in 10 of 12 (93%) women. No patient had evidence of chemical peritonitis. The mean operating time was 87 minutes and the mean postoperative hospital stay was 44 hours. No intraoperative or postoperative maternal or fetal complications occurred. CONCLUSIONS: Laparoscopic removal of a benign cystic teratoma of the ovary may be safely accomplished during pregnancy. In spite of a significant risk of cyst rupture, careful operative technique followed by copious irrigation of the pelvis may avoid chemical peritonitis and potential adverse sequelae.

The case for laparoscopic management of the adnexal mass.

Careful patient selection criteria can be used to identify patients who are appropriate for management of an adnexal masses via operative laparoscopy. Proper intraoperative assessment and liberal use of rapid frozen section are also important for optimal clinical outcome. Reported studies show that laparoscopic management of adnexal masses can be safely done. The short hospital stay and rapid return to normal activity combine to potentially reduce the overall cost of patient care. When cancer is unexpectedly found at the time of laparoscopic surgery for an adnexal mass, the surgeon should be prepared to proceed with staging laparotomy for appropriate treatment.

Patient selection for laparoscopic myomectomy.

STUDY OBJECTIVE: To determine if preoperative criteria could select patients who were likely to be managed successfully by laparoscopic myomectomy. DESIGN: Prospective. SETTING: Two community hospitals. PATIENTS: Premenopausal women who had symptomatic uterine myomata and met the following criteria underwent laparoscopic myomectomy: uterine size less than or equal to 14 weeks after 12 weeks of gonadotropin-releasing hormone (GnRH) agonist therapy; no individual myoma larger than 7 cm; no leiomyoma near the uterine artery, or near the tubal cornua if fertility was desired; and at least 50% of the leiomyoma subserosal, to be accessible and to allow adequate repair of the myometrium through the laparoscope. INTERVENTIONS: Laparoscopic assessment of the pelvis and laparoscopic myomectomy. MEASUREMENTS AND MAIN RESULTS: Forty-one patients entered the study: 23 met the selection criteria and were accepted for laparoscopic myomectomy, but 4 were excluded during laparoscopic assessment of the pelvis. Clinical examination or initial sonogram correctly predicted successful laparoscopic myomectomy in 13 of 19 women. After 3 months of GnRH agonist therapy, clinical examination or sonogram identified four additional candidates. In six patients in whom the optimum approach was still uncertain, laparoscopic assessment found two additional appropriate candidates for laparoscopic myomectomy. Nineteen patients underwent the procedure without the need to convert to laparotomy. None experienced any complications. CONCLUSIONS: Careful patient selection can decrease the likelihood of inappropriate performance of laparoscopic myomectomy and avoid the need to convert to laparotomy.

A multicenter study of laparoscopic management of selected cystic adnexal masses in postmenopausal women.

BACKGROUND: The objective of this study was to determine the ability to predict benign adnexal masses in postmenopausal women and to evaluate the effectiveness of laparoscopic management in selected patients. STUDY DESIGN: Postmenopausal women found to have an adnexal mass were prospectively evaluated with clinical examination, sonography, and serum CA-125 levels. Women with cystic masses greater than 3 cm but less than 10 cm, with distinct borders, without solid parts or septations greater than 2 mm, without ascites or matted bowel, and with serum CA-125 levels less than 35 IU per mL were operated upon by laparoscopy. RESULTS: Sixty-one women gave consent for the study. Cyst size ranged from 3 to 10 cm. All masses were accurately predicted to be benign. Fifty-eight (95 percent) women were successfully managed by operative laparoscopy and three required laparotomy. For the patients managed by laparoscopy, the mean operative time was 63 minutes, the mean postoperative hospitalization period was 12 hours, and the mean return to normal activity was 5.6 days. CONCLUSIONS: The combination of clinical examination, sonographic appearance and serum CA-125 levels can accurately predict benign masses in postmenopausal women. Operative laparoscopy is acceptable for these patients and provides for a short period of hospitalization and a rapid recovery.

Laparoscopic management of the adnexal mass.

Careful preoperative evaluation of women found to have an adnexal mass may select patients for whom operative laparoscopy is appropriate. The role of ultrasonography and serum tumor markers in patient selection is discussed. Operative techniques for the laparoscopic management of the adnexal mass are also presented.
