Small diameter versus conventional laparoscopy: a prospective, self-controlled study.

The objective of this study was to determine visual quality, diagnostic accuracy, and surgical merits of small diameter laparoscopy (SDL). Thirty-seven patients were randomly selected. The indications for laparoscopy were infertility, desire for tubal sterilization or chronic pelvic pain. Patients underwent SDL, followed by conventional laparoscopy (CL) as a control under general anaesthesia. Findings at operation were compared. The mean time for diagnostic work-up was longer with SDL than CL, 11.7 +/- 5.6 versus 7.6 +/- 3.2 min respectively (P < 0.04). Visual quality was scored from 4 to 1 by the operator; mean visual quality, mean endometriosis score and mean adnexal adhesions score were slightly lower with SDL than CL. Sensitivity of SDL in diagnosing endometriosis, adhesions, ovarian, uterine and pouch of Douglas lesions were 71, 58, 81, 89 and 73% respectively; specificity was 100, 96, 100, 100, 100% in the same order. Suction irrigation, cyst aspiration, tissue biopsies, simple adhesiolysis, tubal ligation and cauterization were easily performed with SDL. We conclude that SDL seems a good alternative to CL in diagnosing macro-pelvic anatomy and coarse pelvic pathologies and may also be good in performing surgical procedures such as: tubal ligation, biopsies and differential diagnosis of pelvic fluids. But SDL must be used cautiously in micro-oriented, functional conditions such as infertility, pelvic pain, endometriosis and adhesion scoring or treatment. SDL may be regarded as a less invasive but less sensitive tool with limited surgical merits.

The incidence of congenital malformations in a Turkish population.

OBJECTIVE: To determine the incidence and types of congenital anomalies in a Turkish population. METHOD: The total number of neonates (9160) born in the Department of Obstetrics and Gynecology, Gazi University Faculty of Medicine during 1988-1995 were studied retrospectively. Newborns with congenital anomaly were identified from their birth registries. The total incidence, types and combined anomalies were determined. Also, the relationship between congenital anomalies and maternal age and/or gender were investigated. For statistical evaluation, Chi-square test, Yates correction and Fisher's exact tests were used where appropriate. RESULTS: The overall congenital anomaly incidence was 1.11% and the NTD incidence was 0.27% in our population. Anencephaly was the second most common NTDs with the ratio of 40%, following the spina bifida cases. There was a significant difference between female and male newborns with ancephalocele (P < 0.05). Urogenital system anomalies were found to be the second most common type of malformation with an incidence of 0.21%. Facial and musculoskeletal system abnormalities were the third and fourth most common malformations. Omphalocele incidence in our population was 5 in 9160 births and gastrochisis was 1 in 9160 births. CONCLUSION: The overall congenital anomaly incidence in newborns in our population is 1.11%. The most common malformations were CNS and urogenital abnormalities. NTDs incidence was 0.27% in a Turkish population.

An extraperitoneal burch procedure: a case report.

A new laparoscopic Burch procedure with preperitoneal balloon dissection is introduced. A stress incontinence case without cystocele was operated by laparoscopic extraperitoneal colposuspension. The procedure was found to be effective a year after and no complications were seen. The extraperitoneal Burch procedure has the advantages of easy dissection, less bleeding, pain, and adhesion formation, a lower chance of injury to intraperitoneal organs, and short hospital stay and operation time; but the procedure has the disadvantages of a new anatomy orientation and the additional cost of a disposable balloon dissection set.

Endometrial assessment by vaginal ultrasonography might reduce endometrial sampling in patients with postmenopausal bleeding: a prospective study.

The purpose of this study is to compare transvaginal sonographic endometrial assessment with histology obtained by endometrial curettage in postmenopausal patients and to determine a cut-off point for endometrial thickness to reduce unnecessary diagnostic curettage for postmenopausal bleeding. A total number of 289 postmenopausal women were studied prospectively; 192 patients with postmenopausal bleeding and 97 postmenopausal women without bleeding comprised the study and control groups respectively. All patients were scanned by ultrasound transvaginally, then dilatation and curettage was performed for endometrial evaluation. In all women with and without postmenopausal bleeding, endometrial thickness of 4 mm or less as depicted by sonography correlated well with 'atrophic endometrium' (100%). Of 158 women with an endometrium > 4 mm in both groups, 40 women (25.1%) had a negative result (tissue insufficient for diagnosis or atrophic endometrium), while 118 patients (74.8%) had a positive result which included proliferative and secretory endometrium, endometrial hyperplasia, polyps and cancer. As the endometrial thickness increased, the probability of finding pathology with curettage was increased linearly in postmenopausal bleeding (PMB) positive and negative groups and there was a significant linear positive correlation between PMB (+) and (-) cases (Linear regression, R = 0.91, p < 0.03). A significant difference was found between endometrium carcinoma and all other endometrial pathologies concerning the mean endometrial thickness of 22.7 +/- 10.2 mm (chi-square, p < 0.0001). Also, the mean endometrial thickness of 4.7 +/- 3.3 mm for atrophic endometrium and 6.1 +/- 3.7 mm for 'tissue insufficient for histological diagnosis' were found significantly different than all other endometrial pathologies (chi-square, p < 0.0001). Endometrial thickness of < or = 4 mm may serve as cut-off point for predicting pathology negative cases with an accuracy of 100% in postmenopausal bleeding positive and negative cases. Then as the endometrial thickness increases, the probability of finding endometrial pathology in curettage increases linearly with a positive predictive value of 74.6%.
