 Abstract

- Schwannomas are uncommon neoplasms arising from Schwann cells of the neural sheath. Gastrointestinal
schwannomas are rare, accounting for 1% of all malignant gastrointestinal tumors. Colonoscopic biopsy with
immunohistochemical (IHC) staining is useful for confirming this tumor. We report on a patient with schwannoma
arising from the ascending colon, which was detected by colonoscopy and endoscopic submucosal dissection
was attempted. A 41-year-old man presented with abdominal discomfort. The patient was diagnosed with
a subepithelial tumor on colonoscopy. He underwent endoscopic submucosal dissection. Histopathology and
IHC staining confirmed that the colonic lesion was a benign schwannoma. However, the resection margin was
positive. Therefore, laparoscopic ileocolectomy was performed.

Abstract

- In Korea, cases of direct insertion of foreign bodies into the rectum are rare in the literature. Most cases of rectal insertion of foreign bodies are associated with sexual acts and psychiatric disorder such as schizophrenia. Objects inserted into the anus are usually blunt and shaped like the male genitalia. The removal method can be varied depending on the size and shape of the foreign object, its anatomical location, and the accompanying complications. In cases wherein attempts to remove the object fail or there are rectal perforation and peritonitis complications, immediate laparotomy may be required in order to prevent serious complications such as sepsis. Here, we report on a case of rectal perforation and peritonitis due to insertion of a foreign body in a middle-aged patient, with a literature review. He inserted a sharp pig backbone in his rectum and he only had depression. The patient underwent a Hartmann's operation as well as psychiatric counseling and treatment. Thus, after removal of foreign bodies, psychiatric counseling and treatment should be carried out in order to prevent similar accidents and to minimize the need for trauma medicine.
