A current applied through a rollerball electrode can be used endoscopically to ablate tissue. Its key use is the coagulation of endometrial tissue to a maximal depth of 3mm, so ameliorating menorrhagia. As with transcervical resection of the endometrium and laser ablation, distention of the uterus is required. This is achieved with a glycine solution infusion. Correspondingly, there is a small risk of fluid overload.
Rollerball coagulation takes about 30 minutes and the patient is able to resume normal activity within a week.
