A survey on (operative) laparoscopy in The Netherlands in 1992

Objective: A quantitative inventory of (operative) laparoscopic surgery practiced by Dutch gynecologists in 1992 was made. Methods: A written inquiry was mailed to all 145 departments of Obstetrics and Gynecology (including 28 teaching hospitals), where all 630 practicing gynecologists in The Netherlands are established. The questionnaire included questions about diagnostic laparoscopies, sterilizations, laparoscopy for infertility reason and operative laparoscopies. General information about follow-up training of the practitioner was also collected. All data were analyzed and comparisons were made between teaching and non-leaching hospitals. Statistical significance was calculated with the chi-square test. Results: The response rate was 78%. A total of 419 respondents represented in 99 clinics reported performing 33.676 laparoscopic procedures, which makes an average of 80 procedures per physician per year. Distribution of procedures showed that 36% was for diagnostic laparoscopy, 33%, for tubal sterilization, 19% laparoscopy for infertility work-up and 12% counted for therapeutic laparoscopy. Comparison of procedures in teaching hospitals (n = 27) and non-teaching hospitals (n = 72) showed only slightly more diagnostic laparoscopies for infertility in the first and more tubal-sterilizations in the latter. A statistically significant difference was found for the ring or clip sterilization in teaching hospitals, compared with the coagulation technique in non-leaching departments (P < 0.001). More difficult laparoscopic procedures such as ovarian cystectomy and conservative surgery of ectopic pregnancy were more frequently performed by those who had followed additional laparoscopic training (P < 0.02). Conclusions: The results of this survey are representative for (operative) laparoscopic practice of gynecologists in the Netherlands, because of the high response rate. Relatively, a small proportion of all laparoscopic procedures performed in 1992 are due to the therapeutic laparoscopy (12%). The great majority of therapeutic laparoscopic procedures was reported by a relatively small number of practitioners, Gynecologists who followed an additional laparoscopic training (30%) performed statistically more difficult laparoscopic procedures.
