The Management of Retained Rectal Foreign Body.

Purpose: Because insertion of a foreign body (FB) into the anus is considered a taboo practice, patients with a retained rectal FB may hesitate to obtain medical care, and attending surgeons may lack experience with removing these FBs. We performed this study to evaluate the clinical characteristics of Korean patients with a retained rectal FB and propose management guideline for such cases based on our experience.

Methods: We retrospectively investigated 14 patients between January 2006 and December 2018. We assessed demographic features, mechanism of FB insertion, clinical course between diagnosis and management, and outcomes.

Results: All patients were male (mean age, 43 years) and presented with low abdominal pain (n = 2), anal bleeding (n = 2), or concern about a retained rectal FB without symptoms (n = 10). FB insertion was most commonly associated with sexual gratification or anal eroticism (n = 11, 78.6%). All patients underwent general anesthesia for anal sphincter relaxation with the exception of 2 who underwent FB removal in the emergency department. FBs were retrieved transanally using a clamp (n = 2), myoma screw (n = 1), clamp application following abdominal wall compression (n = 2), or laparotomy followed by rectosigmoid colon milking (n = 2). Colotomy and primary repair were performed in four patients, and Hartmann operation was performed in one patient with fecal peritonitis. No morbidity or mortality was reported. All patients refused postextraction anorectal functional and anatomical evaluation and psychological counseling.

Conclusion: Retained rectal FB is rare; however, colorectal surgeons should be aware of the various methods that can be used for FB retrieval and the therapeutic algorithm applicable in such cases.
