The current status of gynecological laparoscopic surgery in educational facilities in Japan.

A questionnaire survey was administered by Tohoku University hospital to investigate the current status of gynecological laparoscopic operations in teaching hospitals in which residents were trained as obstetricians and gynecologists. Thirty-eight senior doctors in 18 hospitals were sent a postal questionnaire. The response rates of facilities and doctors were 94.4% and 76.3% respectively. Diagnostic and operative laparoscopy was performed in all of the hospitals surveyed, however only a few hospitals performed more than 100 laparoscopies per year, and many surgeons did not perform advanced laparoscopic operations including hysterectomy, myomectomy and lymphadenectomy. Half of the doctors performed minilaparotomy, which is a so-called "open" technique. The standard surgical style involved the use of a carbon dioxide (CO2) pneumoperitoneum and an endoscope 10 mm in diameter. Unipolar endocoagulating instruments were generally used for hemostasis and incision. Most of the doctors surveyed thought that operative laparoscopy would become a necessary procedure in gynecological field, and half of them hoped to receive training in the technique. Instruction of expert endoscopic surgeons is necessary, especially in teaching hospitals, for the spread of safe and advanced laparoscopic surgery. An educational and training system for established surgeons as well as for young residents is urgently needed in Japan.
