OBJECTIVES: To evaluate triple tourniquets in controlled conditions and for the first time to investigate the hypothesis that leaving a semi-permanent tourniquet around the uterine artery reduces post-operative bleeding from the uterine incisions. DESIGN: A randomised controlled trial. SETTING: Two University teaching hospitals. POPULATION: Twenty-eight patients with symptomatic fibroids and uterine sizes ranging from 14 to 24 weeks of gestation undergoing open myomectomy. METHODS: A number 1 polyglactin suture was tied around the cervix to occlude the uterine arteries, and polythene tourniquets were tied around the infundibulopelvic ligament to obstruct the ovarian vessels. At the end of the procedure, the ovarian ties were released but the uterine artery suture remained in situ. MAIN OUTCOME MEASURES: Intra-operative blood loss, post-operative blood loss, blood transfusion rates, operative morbidity, uterine blood flow and ovarian function. RESULTS: There was significantly less blood lost in the tourniquet group than in the control group (difference between means 1870 mL, 95% CI 1159-2580 mL, P < 0.0001; transfusion rates of 7% and 79%, P= 0.0003). The volume in the pelvic drain 20 min post-operatively and after 48 hours failed to reach statistical significance between the two groups (P= 0.10 and P= 0.165). There were no differences in uterine artery Doppler resistance indices at five days (P= 0.54), six weeks (P= 0.47), three months (P= 0.49) and at six months (P= 0.18). Day two serum FSH concentrations after surgery were unchanged (P= 0.45), compared with baseline values. CONCLUSIONS: Triple tourniquets are effective in reducing bleeding and transfusion rates. There appears no obvious adverse effect on uterine perfusion or ovarian function.

BACKGROUND: On the basis of clinical impression that the number of cases of ectopic pregnancy seen in the City and Hackney Health District, London, was changing, a retrospective study of the years between 1990 and 1999 was carried out. METHODS: From the histopathology databases, cases of ectopic pregnancy and early pregnancy failure were identified. The number of deliveries at The Homerton Hospital was obtained from the Labour Ward register; the number of terminations of pregnancy and the number of fertile women was obtained from the Office for National Statistics, UK. RESULTS: There were 73 cases of ectopic pregnancy in 1990 rising to 96 in 1991 and then a fall to 52 cases in 1999. In terms of ectopic pregnancy per 100 deliveries, per all known pregnancies and per 1000 fertile women per year, there was a peak in 1991 and a fall to 1999. With regard to relative incidence per deliveries and per all known pregnancies, these falls were significant (P < 0.05). In 1991, there were 2.4 ectopic pregnancies per 100 deliveries, falling to 1.6 in 1999, a 33% fall. The reasons for this large decline are uncertain. CONCLUSIONS: There has been no change in patient population, diagnostic aids used or management protocols for patients with ectopic pregnancies.

The thickness of the endometrium was measured in postmenopausal women by both the transvaginal and transabdominal ultrasound approaches in two separate groups of patients. The first group consisted of 90 women who received a transabdominal scan of the endometrium before dilatation and curettage or hysterectomy for either postmenopausal bleeding or uterine prolapse. The second group consisted of 111 women who underwent a transvaginal scan of the endometrium for similar postmenopausal conditions. Both methods suggested that an endometrial thickness of 5 mm may be used as a cut-off level in the conservative management of patients with postmenopausal bleeding or in a screening program for endometrial carcinoma. Patient acceptance and image quality were better in the group examined transvaginally. The proximity of the transvaginal probe to the endometrium, in the absence of a full bladder compressing the endometrium, revealed a unique group of patients with atrophic endometrium but thick endometrial cavity caused by intracavity fluid. In the presence of uterine fibroids distorting the uterine cavity, transvaginal scanning was better than transabdominal scanning for visualizing the endometrium. The transabdominal full-bladder technique can be of value in detecting asymptomatic bladder pathology.
RESUMO
Transvaginal ultrasound scanning was performed on 111 postmenopausal women. Of these women, 103 had postmenopausal bleeding, and eight were undergoing hysterectomy. Of the 103 women with bleeding, 93 had dilatation and curettage (D&C) and 10 patients were treated conservatively with a repeat scan in six months. A correlation of ultrasound findings and endometrial histopathology was possible in 94 patients. In 59 of these (63%) the endometrium was atrophic and the ultrasound endometrial thickness was 5 mm or less. In 29 (31%) patients the endometrial histology was abnormal and ultrasound endometrial thickness was greater than 5 mm. In six patients the endometrium was atrophic, but the ultrasonic endometrial thickness was apparently greater than 5 mm due to intracavity fluid. We suggest that an endometrial thickness of 5 mm is an appropriate cut-off level for conservative management of patients with postmenopausal bleeding, or in screening for endometrial carcinoma.

Uterine malformations were detected in 8 of 300 patients (3%) referred for transvaginal ultrasound scan (TVS) for different indications. Six of them had a partially septate uterus and two had a uterus didelphys. As uterine malformations can be associated with both sterility and reproductive failure, we suggest that the study of uterine morphology and structure could be a part of routine TVS examination.

Alphafetoprotein (AFP) levels were determined in 62 patients undergoing termination of first-trimester pregnancy in order to ascertain the incidence of fetomaternal haemorrhage. The apparent frequency of this phenomenon (58%) was higher than that previously reported. There was no evidence of fetomaternal haemorrhage associated with simple bimanual examination.
PIP: As an indicator of the incidence of feto-maternal hemorrhage due to 1st trimester abortion by vacuum aspiration, alphafetoprotein (AFP) levels were determined in 62 women before and after the procedure. The 62 women were grouped as follows: 1) 42 sampled before and after abortion; 2) 8 sampled before, after, and 3 and 6 hours after abortion; and 3) 12 sampled before and after pelvic exam 2 days before. AFP levels rose in 58% of the women assayed immediately after termination, but did not rise further in those assayed 3 and 6 hours later. Pelvic examination had no detectable effect on AFP. The degree of feto-maternal hemorrhage associated with vacuum aspiration was considered sufficient to cause sensitization in rhesus-negative women.

The innervation of the pelvic floor musculature is damaged in both stress urinary incontinence and idiopathic (neurogenic) anorectal incontinence. Because childbirth has been considered to be a causative factor in stress incontinence we have assessed the effect of childbirth on the innervation of the pelvic floor musculature in 122 consecutively referred women. They were investigated 48-72 h and 2 months after delivery; 51 were also studied 6 months prior to delivery. In 45 of these 51 women delivered vaginally, EMG studies of the external anal sphincter muscle showed that the fibre density (FD) increased from 1.38 +/- 0.14 before delivery to 1.57 +/- 0.19 2 months after delivery (p less than 0.01). There was no change in the FD in the external anal sphincter muscle after delivery in 20 women delivered by Caesarean section. The pudendal nerve terminal motor latency (PNTML) measured 48-72 h after delivery was increased in the 102 women delivered vaginally compared to 34 nulliparous control subjects. Analysis of the whole group of 122 women showed that multiparity, forceps delivery, increased duration of the second stage of labour, third degree perineal tear and high birth weight were important factors leading to pudendal nerve damage. Epidural anaesthesia had no effect on pudendal nerve function. Modification of these obstetric risk factors may ultimately reduce the frequency of stress urinary and faecal incontinence in women.

71 women delivered at St Bartholomew's Hospital, London, were studied by electrophysiological tests of the innervation of the external anal sphincter muscle and by manometry. The investigations were done 2-3 days after delivery and again, in 70% of these women, 2 months later. Faecal and urinary incontinence developing after vaginal delivery has been thought to be due to direct sphincter division, or muscle stretching, but the results of the study suggest that in most cases this incontinence results from damage to the innervation of the pelvic floor muscles.
