[Endocystic echography by laparoscopy. 6 preliminary cases]

The decision whether to ablate an ovarian cyst using the operating laparoscope depends on a whole bundle of clinical, biological, ultrasound and laparoscopic factors. But opening a uni or multi-locular fluid containing cyst and exploring its walls can leave the operator in doubt as to whether it is benign, malignant or a borderline lesion. Now it is possible to use 3 mm catheters carrying a rotary ultrasound transducer. When this sound is placed inside a cyst it is possible to study the walls topographically. Six preliminary cases are presented; the increased sensitivity of the pictures obtained by this miniaturised sound make it possible to improve ultrasound diagnosis.
