Preventing hyponatremic encephalopathy: comparison of serum sodium and osmolality during operative hysteroscopy with 5.0% mannitol and 1.5% glycine distention media.

Study Objective: To determine whether isotonic 5.0% mannitol is superior to 1.5% glycine in preventing development of hyponatremic encephalopathy.

Experience with laparoscopic leiomyoma coagulation and concomitant operative hysteroscopy.

Study Objectives: To evaluate the experiences of women who underwent laparoscopic leiomyoma coagulation (myolysis) alone and those who had myolysis in conjunction with transcervical endomyometrial resection (TEMR), transcervical electrosurgical resection of submucous leiomyomas (TSR), or both.

Design: Continuing, prospective observational study with mean (+/- SEM) follow-up of 36.0 +/- 1.

The effect of dilute vasopressin solution on the force needed for cervical dilatation: a randomized controlled trial.

Objective: To assess the force needed to mechanically dilate the cervix of a nonpregnant woman after intracervically injecting dilute (0.05 U/mL) vasopressin solution.

Methods: In a randomized, double-blind study, equal amounts of either a dilute vasopressin solution or placebo (normal saline) were injected into the intracervical stroma at 4- and 8-o'clock positions, just beneath the mucosal surface, in 52 women immediately before cervical dilatation in preparation for operative hysteroscopy.

Relationship of endometrial thickness with the menstrual timing of leuprolide acetate administration for preoperative preparation for hysteroscopic surgery.

Study Objectives: To assess the relationship of menstrual timing of administration of gonadotropin-releasing hormone (GnRH) agonist on the effectiveness of endometrial thinning and unwanted uterine bleeding.

Design: Prospective observational study.

Setting: Gynecology department of a community hospital.

Laparoscopic bipolar coagulation for the conservative treatment of adenomyomata.

Study Objective: To assess the effectiveness of treating adenomyomata with laparoscopic bipolar coagulation.

Design: Prospective, observational study. Setting.

The effect of dilute vasopressin solution on blood loss during operative hysteroscopy: a randomized controlled trial.

Objective: To assess the effect of intracervical injection of dilute (0.05 U/mL) vasopressin solution on blood loss during operative hysteroscopy.

Methods: In a randomized, double-blind study, dilute vasopressin solution or placebo (normal saline) was injected into the cervical stroma of 106 women before dilation of the cervix in preparation for operative hysteroscopy.

Laparoscopic Leiomyoma Coagulation.

From February 1992 through March 1995, 167 women (mean ± SEM age 44.7 ± 0.3 yrs, range 22-52 yrs) with symptomatic leiomyomata underwent laparoscopic leiomyoma bipolar coagulation.

Laparoscopic Bipolar Coagulation for the Conservative Treatment of Adenomyomas.

We assessed the effectiveness of laparoscopic bipolar coagulation in 20 women with severe dysmenorrhea, chronic menorrhagia, and a magnetic resonance imaging diagnosis of adenomyomata. In addition, nine women underwent transcervical endomyometrial resection; three (33.3%) of these women underwent concomitant submucous leiomyoma resection.

The Effect of Dilute 0.25% Vasopressin Solution on the Linear Force Necessary for Cervical Dilatation.

We assessed the force necessary for mechanical cervical dilatation on a nonpregnant uterus after intracervical administration of dilute vasopressin solution 0.05 U/ml. In a prospective, double-blind, randomized study, vasopressin or placebo was injected into the cervical stroma before dilating the cervix in preparation for resectoscopy.

The Effect of Dilute Vasopressin Solution on Blood Loss During Operative Hysteroscopy.

A study was designed to assess the effect of intracervical injection of dilute vasopressin solution 0.05 U/ml on intraoperative blood loss during operative hysteroscopy. In a prospective, computer-randomized, double-blind study, vasopressin or placebo (normal saline) was injected into the cervical stroma of 108 women before dilatation of the cervix.

Chemical Changes in the Blood During Operative Hysteroscopy Using 5.0% Mannitol versus 1.5% Glycine.

This study compared the changes in blood chemistry that occur during operative hysteroscopy when either 5.0% mannitol or 1.5% glycine is used as a distention medium.

Magnetic resonance imaging for diagnosing adenomyomata.

Study Objectives: To evaluate the accuracy of magnetic resonance imaging (MRI) for diagnosing nodular adenomyosis by percutaneous myometrial biopsies.

Design: Prospective observational study.

Setting: Gynecology department of community hospitals.

100 laparoscopic hysterectomies in private practice and visiting professorship programs.

Study Objective: To evaluate 100 laparoscopic hysterectomies and their variations in private practice and visiting professorship programs.

Design: A prospective observational study.

Setting: Gynecology departments of 17 teaching, community, and proprietary hospitals in the northeastern United States.

Transcervical electrosurgical resection of submucous leiomyomas for chronic menorrhagia.

Study Objective: To evaluate the effectiveness and safety of transcervical electrosurgical resection (TSR) of submucous leiomyomas with or without concomitant transcervical endomyometrial resection (TEMR) for chronic menorrhagia.

Design: Prospective observational study, with 6-month follow-up of all 208 women and up to 6-year follow-up of 185 (88.9%).
