Abstract:
PURPOSE: This study investigated the clinicopathological features and surgical procedures of adnexal masses with abdominal pain in pediatric and adolescent patients. Our objective was to better define the clinical presentation of adnexal torsion and to distinguish characteristics of those with torsion and those with an alternate diagnosis. METHODS: Retrospective cohort study of 212 pediatric and adolescent patients was performed who admitted for abdominal pain and presenting with an adnexal mass between March 2012 to December 2019.Medical records were reviewed for age at operation, including presentation of symptoms and signs; the levels of tumor markers; imaging examinations; pathologic findings; the size of masses; treatment; and outcome. Data management and descriptive analyses were performed using SPSS 26.0. RESULTS: The median age of the patients was 14.5 ± 3.6 years at the operation. 126 (59.4%, 126/212) patients presented with an abrupt onset of abdominal pain. A total of 82.1% (174/212) of the participants underwent adnexal conservative surgery. 179 (84.5%, 179/212) patients underwent laparoscopic surgery with an average tumor size of 7.7 ± 3.4 cm, while 33 patients ( 15.6%, 33/212) underwent laparotomy. Rupture of mass and ectopic pregnancy accounted for 7.5% (16/212) and 0.9%(2/212), respectively. Torsion was responsible for 36.8% (78/212) of all patients. Among the patients with torsion, the symptom of nausea and vomiting was more common among girls without torsion (P < 0.0001). 88.5% of the girls with torsion had acute onset of abdominal pain, while 92.3% had persistent pain that could not be relieved or occurred repeatedly, which significantly higher than that in the patients without torsion (P < 0.001). 69.2% of patients with torsion had fixed pain sites, compared with 42.2% in patients without torsion (P < 0.001). 88.5% of girls with torsion had an ovarian cyst/mass ≥ 5 cm, compared with 75.0% in girls without torsion (P = 0.038). 66.7% of girls underwent ovary-preserving surgery, compared with 92.2% in patients without torsion. The most common pathologic types were mature teratoma and simple cyst, accounting for 29.4% and 25.6%, respectively. The multivariate analyses confirmed that mass size greater than 5 cm (OR 4.134, 95% CI: 1.349-12.669,P = 0.013), acute onset pain (OR 24.150,95%CI: 8.398-69.444,P = 0.000), persistent or recurrent pain (OR 15.911,95%CI: 6.164-41.075,P = 0.000) were significantly associated with increased risk of torsion. CONCLUSIONS: Torsion which is a relatively rare event in the pediatric population was not an uncommon condition and responsible for more than one third of all pediatric and adolescent patients presented with adnexal masses and abdominal pain. Pain assessment in children and adolescents is important to distinguish characteristics of those with torsion and those with an alternate diagnosis.Thus, pediatric and adolescent patients particularly with a pelvic mass size greater than 5 cm, acute onset pain, persistent or recurrent pain have a benign cause and not missing the devastating condition that needs emergent attention. Thus, a strategy of earlier and liberal use of Diagnostic Laparoscopy (DL) may improve ovarian salvage.
