Laparoscopy on patients with previous lower abdominal surgery: a new technique.

During the period June 1979--May 1981, 1582 diagnostic and operative laparoscopic procedures were performed at Al-Azhar University Endoscopy Unit and during field visits to several hospitals in Egypt, Sudan and Mauritania. Ninety-nine of these had had previous lower abdominal surgery. Laparoscopy was performed on 93 of these patients using a modified technique of laparoscopy. The modified technique involves direct visualization of the previous peritoneal scar with the scope before its careful puncturing with the trocar and cannula. The paper describes the technique, findings, complications, limitations of the procedure and its application.

Menstrual pattern and blood loss with U-coil inert progesterone-releasing IUDs.

Menstrual blood loss (MBL) was estimated before and after insertion of the U-coil progesterone-releasing device in 37 patients. The same procedure was carried out in 39 cases fitted with an inert U-coil IUD of the same size and shape. Blood loss was estimated by the atomic abosorption technique during the preinsertion cycle and at the 1st, 3rd, 6th, 9th, and 12th postinsertion cycles. MBL was significantly reduced in patients fitted with a progesterone-releasing U-coil compared to those fitted with an inert U-coil who showed a significant increase in MBL. The cycle length was prolonged with the progesterone U-coil, and was reduced with inert U-coil devices. The duration of flow was significantly reduced with the progesterone U-coil and significantly prolonged with the inert device. The incidence of intermenstrual spotting was higher with the progesterone U-coil than with the inert U-coil. The hemoglobin level was significantly increased with the progesterone U-coil while it was significantly reduced with inert U-coil devices.

Perinatal mortality in an Egyptian maternity hospital.

The factors affecting perinatal mortality during a period of 21 months were studied at Al-Galaa Teaching Hospital, using the International Fertility Research Program's Maternity Record 903 to collect the data. There were 6990 deliveries during the 21 months and 580 hospital perinatal deaths. Certain high-risk factors associated with perinatal mortality were identified including both biosocial and biomedical factors. The biosocial factors affecting perinatal mortality in this study are discussed, including maternal education, marital status, residence, hospital status as paying or non-paying patient, maternal age, registration status, outcome of last pregnancy, parity/family size, antenatal care, maternal hemoglobin, and the weight and sex of the baby.

The benefit of lactation amenorrhea as a contraceptive.

A group of 148 lactating women who delivered normally at El-Galaa Hospital, Cairo, were followed up monthly for 1 year to study the pattern of lactation amenorrhea, the return of menstruation and ovulation, and the incidence of pregnancy. By the end of the sixth week postpartum, only 1.3 percent of the women had begun menstruating; the percentage gradually increased to 60.2 percent by the end of the first year. The amount of blood loss and the duration of menstruation increased gradually until the fourth postpartum menstrual period. Ovulation had occurred in 58.1 percent and pregnancy in 26.1 percent of all cases at the end of the 12th postpartum month. Among menstruating, lactating mothers, ovulation occurred in 86.5 percent and pregnancy in 32.6 percent, while in amenorrheic, lactating mothers only 6.1 percent had become pregnant at 1 year postpartum.

Medicated intrauterine devices to improve bleeding events.

In an attempt to find an IUD that will cause a minimum amount of blood loss, while continuing to be effective and easily retained, we are studying 4 medicated IUDs: a copper-bearing Lipps Loop, a Copper-T-200, a progesterone-releasing U-coil, and a tranexamic-acid-releasing Lippes Loop. Inert devices of the same shape and size are used as controls. This is a comparison of the findings on menstrual blood loss and loss and changes in bleeding patterns for patients using the plain and copper-bearing Lippes Loops. Preliminary results for the progesterone-bearing U-coil and the tranexamic-acid-releasing Lippes Loop are also given, but studies of these devices are not yet complete.
