Introduction: Clinical and radiographic findings often lead to diagnostic laparoscopy for presumed adnexal torsion (AT). To better understand the preoperative factors leading to AT, we evaluated the clinical course of patients with ultrasound findings concerning for AT to assess intraoperative AT rates and predictive factors for AT.
Methods: An institutional review board-approved retrospective review in two hospital centers over a period of 5 y was performed for females (4-18 y) with ultrasound (US) findings concerning for AT (n = 225). Preoperative clinical, radiographic, and intraoperative findings were assessed for patients with intraoperative AT versus for those without.
Results: The median age of patients was 14 y. Of those who went to the operating room (OR) (n = 113), AT was found in 57%. There was no difference between patients taken to the OR with or without AT regarding demographics or presentation. The presence of nausea/vomiting, tenderness, leukocytosis, lack of blood flow, or a mass/cyst >5 cm were found to be more likely in patients with AT than in those without. An ovarian volume ratio >15 was noted to be predictive of AT. Six patients initially discharged from the emergency department returned and went to the OR, two of which had AT, both with ovarian salvage.
Conclusions: Limited data are available when counseling patients with presumed AT. We found the larger mean ovarian volume and an ovarian volume ratio >15 were predictive of AT. Despite this, 43% of patients taken to the OR did not have AT. This relatively high rate of not finding AT intraoperatively may be justified given the sequelae of missing AT.
