The aim with the study is to compare postoperative pain after vNOTES adnexal surgery versus laparoscopic adnexal surgery.

Women aged 18 and above with an indication for adnexal surgery for benign gynecological pathology or prophylactic reasons will be able to participate.

After surgery the participants will answer a questioner, twice a day in seven days, about postoperative pain and how many units of analgesics they used.

Adnexal surgery is one of the most common surgical procedures performed in women and can either be performed to treat pathology as ovarian cysts or prophylactically in case of hereditary genetic alterations.

A laparoscopic technique is currently considered as gold standard for adnexal procedures. The latest advancement in minimally invasive surgery is vNOTES (vaginal natural orifice transluminal endoscopy), in which the entrance to the abdomen is performed by an anterior or more commonly posterior colpotomy rather than via the abdominal wall. The NOTABLE trial was a RCT showing that vNOTES adnexectomy was non-inferior to laparoscopy for successful removal of benign adnexa without conversion (Baekelandt). vNOTES adnexectomy had shorter surgical time, less use of analgesics and lower self-assessed VAS scores the first week post-operatively. The aim with our study is to compare postoperative pain after vNOTES versus laparoscopic adnexal surgery.
