Foreign Body Insertions: A Review
In nearly half of the reported cases, the reasons for rectal insertion was for sexual arousal/stimulation.1,7 Other reasons include nonsuicidal injurious behavior (eg, borderline personality disorder); suicide attempt; psychosis; depression; factitious disorder; malingering; cognitive disorders, including dementia and delirium; treatment of constipation and hemorrhoids; concealment; attention-seeking behavior; “accidental”; assault; and the consequences of drunken wagers.1,2 Additionally, abuse should be considered, especially in patients with developmental delay and/or psychiatric illness.
Close to 20% of all traumatic rectal injuries are due to foreign body insertions. In most cases, foreign bodies fail to cause significant anorectal injuries. Complications, however, can result from the process of insertion, removal, or from the contents introduced into the orifice.1 Any rectal examination should be preceded by an anatomical survey utilizing radiographic modalities to evaluate the integrity and orientation of the object in question. Any sharp object can injure the examining physician if this is not done prior. All examinations should be chaperoned.2,7 The most obvious and dangerous complication is perforation, and the patient’s care should proceed in the same manner as any other trauma patient. Additionally, resulting sepsis should be managed with the same standards as any other septic patient.7
Treatment. The method of object removal is determined by the presence or absence of a surgical abdomen and the need for general anesthesia. The location and shape of the object, however, may not equate with successful retrieval. Objects placed in the sigmoid colon are more than twice as likely to require surgical intervention compared to items placed distally.2 Once it is determined that the patient is clinically stable and does not have an acute abdomen, attempts in removing the rectal foreign object can be done in the ED or, if anesthesia is needed, in the OR. Any attempts at transanal removal require optimal patient relaxation, which can be achieved via procedural sedation. The patient should be placed in a lithotomy or left lateral decubitus position to allow palpation of the object in the lower gastrointestinal tract. From here, several methods of removal can be employed. Blunt objects can be grasped and removed by a gloved hand or with a clamp. A Foley catheter can also be passed alongside the object and the balloon inflated above the foreign body to aid in extraction as the Foley is pulled out slowly. Sengstaken-Blakemore tubes, obstetric forceps, and vacuum extractors have also been utilized.7
While bedside extraction is advocated by many authors, Cawich et al8 recently reported that transanal extraction in the ED failed in 89% of cases. Additionally, these researchers reported that in 63% of the failed extractions, the objects were inadvertently pushed higher into the rectosigmoid region, and therefore recommended early mobilization of the OR team so that exploration under anesthesia can be performed under optimal conditions.8
Once the foreign body is successfully removed, follow-up imaging or postextraction endoscopy is warranted. Close observation in the hospital is recommended to facilitate serial abdominal examination.7
Urethral Insertions
Sexual exploration, efforts at contraception, transport of illicit drugs, assault or sexual violence, and accidental insertion have all been described as reasons for genitourinary (GU) insertion.1 The motives, however, mirror those who insert foreign bodies rectally.
Most presentations are due to pain or inability to void. Aggressive treatment should be undertaken because even when the penis appears dark or necrotic, salvage rates have been high. Complications include urinary tract infections, hematuria, urinary retention, urethral tears, abscess, ascending GU infections, and diverticula and fistula formations.1,3 In women, vaginal insertions can lead to pelvic pain and septic shock.1 Foreign bodies can also lead to a condition first described in the ancient literature as strangury—the process of slow and painful discharge of urine due to a significant inflammatory component or stricture. The term strangury has been replaced with the more general term bladder spasms.9
Treatment. Removal of urethral foreign bodies typically is done in conjunction with a urologist. A cystoscopic procedure is usually successful in removing the foreign body and is an effective method to minimize urethral and bladder injuries. However, more invasive surgical options, including perineal urethrotomy, suprapubic cystostomy, cystolithotomy, and external urethrotomy, have been used in more complicated cases or when the foreign body prevents urethral access of an endoscopic instrument.10
Patient and Staff Reactions
When patients realize they are unable to remove the inserted object, some present immediately to the ED for evaluation. Interestingly, others may wait up to 2 weeks after insertion before seeking help.2 Patients report feelings of being ashamed and report a feeling of being despised, frowned upon, and being talked about during the course of their ED evaluation. As a consequence, these patients may not readily come to the ED or if they do come, may not be open to conversation and hide the true reason of why they came in the first place.1,4 The amplified paranoia and perceived prejudice may delay diagnosis and lifesaving measures, or worse, lead patients to leave prior to a medical screening examination. Therefore, creating a nonjudgmental environment is essential, even when the presenting story appears to be fabricated.2
