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.

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.

Histophysiological studies of prostaglandin F2alpha on isolated organs. I. Effect of prostaglandin F2alpha on the heart.

The physiological and histochemical effects of PGF2alpha on isolated rabbit hearts were examined. The results showed a positive inotropic effect. The coronary flow increased. From the histochemical studies, adenosine triphosphatase (ATP-ase) and succinic dehydrogenase activities were increased while that of alkaline phosphatase was decreased. Glycogen granules were depleted. These findings were discussed on a histophysiological basis.

Minilaparotomy for female sterilization: a feasibility study of a new technique.

Female sterilization via a minilaparotomy incision was performed on 30 patients at Al-Azhar University Teaching Hospital in Cairo, Egypt. A uterine sound fed through a Foley catheter was used as a uterine elevator. A 2 cm suprapubic transverse laparotomy was performed and sterilization was accomplished by fimbriectomy. Twenty patients received general anesthesia and 10 patients initially received local anesthesia. Surgical time ranged from 7 to 15 min, and the average duration of hospitalization was 8 hours. Blood loss was small, and no patient was transfused. One patient had a wound infection. This pilot study indicates that this procedure is relatively simple, safe and inexpensive.
