Systematic Literature Review of Pediatric Male and Female Genital Hair Thread Tourniquet Syndrome.

OBJECTIVE

The aim of this study was to describe genital hair thread tourniquet syndrome (HTTS) and its treatment by pediatric and adolescent health care providers through a systematic literature review.

METHODS

We performed a systematic literature review on pediatric male and female genital HTTS. Studies were included if they involved genital HTTS in males or females 21 years and younger and were published in English. The main outcomes were body parts involved, symptoms, treatment, anesthetic type, providers involved in diagnosis and management, and implications of delayed or missed diagnosis.

RESULTS

There were 38 female cases from 33 publications (1973-2020) and 147 male cases from 47 publications (1951-2019). The average age among females and males was 9.1 and 5.1 years, respectively. Among cases involving female patients, 93% of them were premenarchal; patients were circumcised in 90% of reviewed cases of male HTTS. The most commonly involved body parts were clitoris and labia minora in females, and penis and urethra in males. Males most commonly presented with edema and urinary symptoms, whereas females most commonly presented with edema and pain. General anesthesia was used for tourniquet excision in most cases. Male and female genital HTTS were mostly managed by urologists and emergency medicine physicians, respectively.

CONCLUSION

This systematic literature review of more than 150 cases of male and female genital HTTS describes evaluation and management of genital HTTS spanning 7 decades. The main treatment of genital HTTS remains prompt diagnosis and removal of the tourniquet, as well as education on prevention strategies. Delayed diagnosis due to lack of recognition of the HTTS can lead to serious sequelae. Development of national guidelines regarding best practices in management of genital HTTS disseminated to all providers taking care of pediatric and adolescent patients will lead to improved patient care.
