Suture loop techniques to facilitate microsurgical and laparoscopic procedures.

Suture loop techniques have been devised to facilitate suture tying during microsurgical and laparoscopic procedures. The needle-through-the-noose technique involves making a knot by passing the needle of a suture through a noose loop formed near the distal end of the suture. This technique prevents inadvertant slippage of the suture's free short end through tissues, replaces the difficult first throw with simple passage of a needle through a noose and equalizes the amount of tension applied on the suture as it slides smoothly within the noose. The needle-through-the-noose knot can stand alone with continuous sutures but requires one more tie in interrupted sutures. The clock loop technique is based on turning the suture clockwise and counterclockwise for making square knots with instruments.

Clinical experience with intrauterine devices in a private practice.

Clinical experience with intrauterine devices was evaluated, based on 627 insertions over a 14-year period in a private practice. Overall, there were few differences in the event rates leading to IUD discontinuation for the IUDs evaluated, principally Cu-7, Dalkon Shield and Lippes Loop. Pelvic infections were infrequent (0.7-2.2 cases per 100 woman-years of IUD use). The rate of PID in the study population appeared to be similar to that noted in the general population. IUD use did not appear to compromise future fertility, based on evaluations of patients after removal of their IUDs or from their return to fertility following IUD removal. IUD event rates (pregnancy, expulsion, displacement, removal for bleeding and/or pain) were related to the difference between endometrial cavity length and IUD length. A significant increase in the event rates was noted, regardless of the IUD type, when the endometrial cavity length exceeded IUD length by 2.0 cm or more, or when the difference between the endometrial cavity and IUD length was less than 0.5 cm.

Open laparoscopy for tubal occlusion in the female.

Open laparoscopy was performed in 630 patients seeking permanent contraception for health reasons. Various electric and mechanical tubal occlusion methods were utilized. With few exceptions, uterine curettage was performed at the end of the laparoscopic procedure. Curettage revealed unexpected findings in 10 cases. Laparoscopic exploration of the peritoneal cavity showed pathologic findings in 10% of the patients. There were no intraoperative complications related to open laparoscopy. Fourteen patients (2%) underwent immediate laparotomy, to manage unexpected findings in six and to correct complications of unipolar tubal cautery technique in eight. Postoperative complications possibly related to open laparoscopy were limited to minor wound infection in 0.3% and febrile reaction of short duration in 0.1% of the cases. Two sterilization failures occurred in the series, both following unipolar techniques employing coagulation and resection. Many patients have now been followed for 5 or more years without noticeable increases in complaints of uterine bleeding and/or pelvic pain. The data indicate that open laparoscopy is a suitable means of performing tubal sterilization in the female.

Open laparoscopy.

Many of the complications of conventional closed, or sharp, laparoscopy result from the use of insufflation needles and sharp trocars. These instruments are not essential elements of the technique as laparoscopy can be easily performed with a small umbilical incision, entering the abdomen under direct vision. This variation is called open laparoscopy. Open laparoscopy eliminates the possibility of insufflation-needle and trocar injuries and lessens the probability of failed laparoscopy attempts and postoperative herniations. Furthermore, physicians performing open laparoscopy can become comfortably proficient in the technique faster than they can in closed laparoscopy because open laparoscopy utilizes standard and familiar surgical technique. Open laparoscopy can be easily performed under local anesthesia, particularly for female sterilization. The technique is suitable for the outpatient setting based on considerations of safety and reliability.

Uterine geometry and IUCD design.

The endometrial cavity is an isosceles trapezoid that changes in shape with the phase of the cycle. The distance from the fundus to where the cavity narrows to 12 mm is the effective length. This and the total length of the uterine cavity can be measured with the Wing Sound. IUCD complications are more frequent if the length of a device exceeds the effective length or the width of the uterine cavity. Devices must be designed to fit the uterine cavity and to conform to physiological changes in the shape of the organ.

Electrocoagulation of pelvic endometriotic lesions with laparoscopic control.

Twenty-eight patients presenting with initial complaints of infertility or chronic pelvic pain were found to have pelvic endometriosis at laparoscopy. Destruction of the endometriotic lesions by means of electrocoagulation was performed via laparoscopy in a group of 19 patients. The remaining nine patients did not undergo such management. In the treatment group, seven of the 11 patients with chronic pain experienced complete relief of their symptoms, and six of the eight patients with infertility became pregnant postoperatively. Patients in the control group had a less favorable outcome. Only one of five patients with chronic pain had relief and one of four patients with infertility became pregnant following laparoscopy without cauterization. Electrocoagulation of pelvic endometriotic lesions under laparoscopic control appears to be satisfactory for the management of selected patients with chronic pelvic pain or infertility.

Factors that affect IUD performance: a review and recommendations.

IUD design features that affect performance are reviewed and discussed. The use of a medicated device designed to be placed, retained and stabilized exclusively in the frontal plane of the upper uterine segment fulfills theoretical conditions of optimum performance.

Topical uterine anesthesia: a preliminary report.

The instillation of 1 to 6 ml of 1% lidocaine was evaluated as a topical anesthetic method of reducing pain associated with uterine manipulations during gynecologic procedures. A plastic acorn cannula connected to a metal adapter and syringe was used to administer the topical anesthetic in 146 intrauterine device insertions, 16 cervical dilatations, and 18 dilatation and curettage procedures. Most patients reported satisfactory relief of pain. No complications were attributed to the topical anesthetic.

Factors affecting intrauterine contraceptive device performance. I. Endometrial cavity length.

The relationship of endometrial cavity length to intrauterine contraceptive device (IUD) performance was evaluated in 319 patients wearing three types of devices. The rate of events, defined as pregnancy, expulsion, or medical removal, increased significantly when the length of the IUD was equal to, exceeded, or was shorter by two or more centimeters than the length of the endometrial cavity. Total uterine length was found to be a less accurate prognostic indicator of IUD performance than endometrial cavity length alone.

A new sutureless technique for skin closure.

A sutureless wound-closure device was used in 150 patients. The average time spent to effect skin closure was reduced; removal was easy; skin apposition was satisfactory; and patient response was favorable. Sutureless tape closures eliminate the disadvantages of invasive skin closures. The device described provides secure tape adhesion to the skin and does not cover the wound. It can be easily applied, adjusted, and removed, in addition to serving as a protective splint to the healing wound. This method can reduce operative time of skin closure with highly satisfactory cosmetic results.
