Analysis of Medicolegal Examination in Alleged Sexual Abuse Presented to a Tertiary Care Hospital in Sri Lanka

Forensic experts are often expected to provide an opinion on alleged physical or sexual contact between individuals following medicolegal examination of a case of sexual abuse (SA). There are many factors influencing the opinion. A retrospective descriptive study was performed to study the factors influencing the medicolegal opinion in SA forensic examination using medical and medicolegal records of alleged SA victims to extract data. Records of 441 victims were studied. A majority, 180 (40), presented due to the guardian's concerns - 302 (68) presented for medicolegal examination 72 h after the incident. Recent injuries were observed in only 15 of the victims. Genital injuries were observed in 74 of the victims brought due to concerns of the guardians, with 12 victims having recent injuries. Of the 172 victims who complained of vaginal intercourse, 21 had recent injuries. A firm positive medicolegal opinion could be given in 63 of all cases. In 124 individuals, a firm positive or negative opinion could not be given. A majority (n = 90, 73) of these individuals did not have any injuries, while 23 had healed injuries. According to the nature of the complaint, in a significant number of victims (53), no scientific evidence was present to make a firm opinion. The nature of the sexual act and the absence of injuries influence the medicolegal opinion on SA, making it a challenging task for forensic experts.
