Sterilization failures in Singapore: an examination of ligation techniques and failure rates.

The University Department of Obstetrics and Gynecology, Kandang Kerbau Hospital in Singapore, initiated a study in early 1974 of failure rates for various methods of sterilization and the factors responsible for the failures. During the period January 1974 to March 1976, 51 cases of first pregnancy following ligation were discovered. Cumulative failure rates at 24 months were 0.34 per 100 women for abdominal sterilization, 1.67 for culdoscopic, 3.12 for vaginal, and 4.49 for laparoscopic procedures. Findings for 35 patients who underwent religation showed that recanalization and the establishment of a fistulous opening caused the majority of failures. Clearly, more effective methods of tubal occlusion in sterilization are needed.

The safety of combined abortion-sterilization procedure.

To determine the safety of tubal sterilization performed at the time of induced abortion, we compared data on 616 women who underwent induced abortion and concurrent tubal ligation (Group 1) with 1,805 women who had induced abortion only (Group 2). These two groups of women were healthy, seven to 12 weeks pregnant, and between the ages of 16 and 44 years. The partly-standardized morbidity rates for Group 1 and Group 2 were 5.4 and 3.6%, respectively. Thus, the sterilization procedure added 1.8% to the complication rate of induced abortion only. The complication rate for women who had interval culdoscopic ligation under the same conditions in the same department was 2.4%. This is not significantly different from the complication rate of 1.8% attributable to sterilization procedures in women who had abortion and concurrent ligation. We conclude that these data support our present practice of performing tubal ligation at the time of induced abortion, rather than changing to the practice of abortion followed by interval sterilization six weeks later, with its many disadvantages to the patient as well as to those providing family-planning services.

Diagnostic miniculdoscopy preceding laparoscopy when bowel adhesions are suspected.

Suspected bowel adhesions are often considered a relative contraindication to laparoscopy. To attempt preoperative diagnoses of intraabdominal adhesions, miniculdoscopy was performed on ten patients with a miniendoscope. It was possible to establish the presence or absence of adhesions and to determine a safe abdominal trocar insertion site. The laparoscope trocar could be inserted under direct controlled vision with the culdoscope in nine cases, suggesting that this procedure averts bowel adhesions. This technique may be a contribution to safer laparoscopy.

[The role of culdocentesis in the diagnosis of ectopic pregnancy. Prospective study of 478 cases].

Four hundred and seventy height Culdocenteses were carried out in cases of possible ectopic pregnancy between the 20th September 1986 and 31st December 1987. Culdocentesis was considered to be positive if 2 cm3 or more of dark non-coagulated blood was removed, and negative if only a yellow liquid or blood stained serum was removed. It was not conclusive if nothing could be aspirated or if the blood was coagulated. Of the 94 cases where culdocentesis was positive, 74 were found to have an ectopic pregnancy. There were 20 false positive cases (due to 5 haemorrhagic ruptures of follicles, 3 refluxes of menstrual blood, 2 with other aetiology, and 10 without known cause). There were 21 cases of ectopic pregnancy in the 293 cases where culdocentesis was non-conclusive. Of the 91 cases where culdocentesis was negative, a second culdocentesis showed an ectopic pregnancy. It was positive 11 days after the first. In our series this diagnostic test was reliable in 77.1% of cases. Laparotomy was carried out in 22.3% of cases and only 18.6% had to have laparoscopy thanks to the use of culdocentesis.

Ectopic pregnancy at Tikur Anbessa Hospital, Addis Ababa, Ethiopia, 1981-1987: a review of 176 cases.

Between September 1981 and August 1987, 242 cases of suspected ectopic pregnancy were admitted to Tikur Anbessa Teaching Hospital, Addis Ababa, Ethiopia, of which 231 were confirmed at laparotomy. Over the same period of time 28,600 deliveries were conducted in the same hospital, giving a ratio of eight ectopic pregnancies to 1,000 deliveries. Review of the 176 cases records which could be retrieved revealed that 57.9% were in the age group of 20-29 years and 27% were nulliparous. The history revealed lower abdominal pain in 98.8%, amenorrhoea in 82.9% and vaginal bleeding in 73%. On clinical examination, 92% had lower abdominal tenderness, 80.6% cervical excitation tenderness, 26.7% a mass in the adnexa and 31.2% a haemoglobin level of 7 gm percent or less. In 51.7% of the cases the ectopic was on the right and in 44.4% on the left. In 37.5% of the cases more than 1,000 millilitres of blood was contained in the peritoneal cavity. Only two were cases of unruptured ectopic pregnancy. There were 5 (2.8%) cornual and 2 (1.1%) ovarian pregnancies. Culdocentesis was the most reliable diagnostic test. In the 176 cases, repeat ectopic occurred in 7.3%. In a situation like ours, where adequate diagnostic facilities are not available, ectopic pregnancy should always be suspected in women with lower abdominal pain and amenorrhoea, or lower abdominal pain and irregular vaginal bleeding.

Role of qualitative choriogonadotropin assays in diagnosis of ectopic pregnancy.

We compared the clinical sensitivity and cost-effectiveness of a qualitative assay for choriogonadotropin in human urine ("Icon" hCG) with a quantitative assay of serum from 142 women with pathologically-diagnosed ectopic pregnancy. Results show that although the qualitative assay had a clinical sensitivity for pregnancy of 98.6%, as compared to 100% for the quantitative assay, it was more economical to use, and had a significantly shorter turnaround time. We conclude that qualitative hCG assay of either urine or serum is a good screening method for detecting pregnancy, and can replace the stat quantitative assay in women with suspected ectopic pregnancy. We present a diagnostic algorithm to illustrate the role of qualitative and quantitative hCG assays in conjunction with ultrasonography, culdocentesis, and laparoscopy for diagnosis of ectopic pregnancy.

[Ultrasonographic diagnosis of cul-de-sac endometriosis].

Fifty-six women with endometriosis were examined for cul-de-sac endometriosis by ultrasonography and laparoscopy. Ultrasonographic cul-de-sac findings were classified into 3 groups; i.e. Group A (n = 21): no remarkable findings, Group B (n = 16): several nodular hyperechoic or cystic hypoechoic areas, and Group C (n = 19): multiple nodular or cystic areas and/or discontinuation of the contour of the posterior uterine wall. Laparoscopic cul-de-sac findings were classified into 3 groups; i.e. Group alpha (n = 6): no endometriosis, Group beta (n = 28): minimal or mild endometriosis, and Group gamma (n = 22): advanced endometriosis with or without cul-de-sac obliteration. Over-all coincidence of both findings was 50%. The rate of coincidence was significantly higher (p less than 0.05) in Group gamma (15/22) than in Group beta (9/28). This indicates that the diagnosis of minimal or mild cul-de-sac endometriosis by means of ultrasonography is difficult but that ultrasonography might be useful in diagnosing advanced cul-de-sac endometriosis.

Reproductive uterine surgery.

Uterine reconstructive surgery may be accomplished through both the abdomen and the hysteroscope. It is important to obtain a complete evaluation of infertility or repeated pregnancy wastage prior to surgery. Newer approaches include the hysteroscopic resection of the uterine septum and medical therapy with GnRH analogues for reduction of fibroid size, volume, and symptoms. In some instances, larger fibroids may be approached through the hysteroscope or resectoscope after medical therapy.

[The hysteroscopic treatment of Asherman syndrome].

In the period January 1978 until December 1985 14 patients were hysteroscopically diagnosed as having Asherman syndrome. All patients had had a history of a curettage after termination of pregnancy and/or hypo-amenorrhoea. Excluded from the series were patients with thin intra-uterine senechiae which were easily broken down with the hysteroscope itself. No patient was excluded because of other infertility factors. Of the 14 patients, 10 were hysteroscopically treated by means of lysis with microscissors; of the remainder 3 were not treated because the hospital did not have microscissors at that time and 1 patient was already postmenopausal. Postoperatively, a Foley catheter was placed in the uterine cavity for 3 days. Cyclic steroid hormone therapy was not used except in 1 patient. Of the 10 treated patients, 5 became pregnant; all were delivered of live babies.

Hysteroscopic pictures following danazol therapy in endometrial hyperplasia.

Danazol is a synthetic steroid derived from ethisterone. Ten women with menometrorrhagia have been treated in order to demonstrate the modifications induced by Danazol on hyperplastic endometrium. Histological and hysteroscopic control demonstrated that Danazol Therapy, at a dose of 200 mg/die, is an efficacious treatment for endometrial hyperplasia.
