Colonoscopic Removal of an Intrauterine Device That Had Perforated the Rectosigmoid Colon

The intrauterine device (IUD) is a widely used contraceptive method. One of the most serious and rare complications of using an IUD is colon perforation. We report a case of colonoscopic removal of an IUD that had perforated into the rectosigmoid colon in a 42-year-old woman who presented with no symptoms. Colonoscopy showed that the IUD had penetrated into rectosigmoid colon wall and that an arm of the IUD was embedded in the colon wall. We were able to remove the IUD easily by using colonoscopy. The endoscopic approach may be considered the first choice therapy for selected patients.

A Case of Gastric Intramural Hematoma after Endoscopic Injection of Hypertonic Saline-Epinephrine for Hemostasis

A gastric intramural hematoma is very rare and commonly associated with trauma, anticoagulation therapy, coagulopathy, pancreatic disease, aneurysm and peptic ulcer disease. This is a case of gastric intramural hematoma which occurred in a patient taking aspirin after hypertonic saline-epinephrine injection for bleeding from a biopsy site. We describe a case of gastric intramural hematoma that was successfully managed with conservative therapy.

A Case of Febrile Colonic Tuberculosis that Became Defervescence after Colonoscopic Polypectomy / 대한소화기내시경학회지

The clinical manifestations, radiological and endoscopic findings of colonic tuberculosis are non-specific. A diagnosis of colonic tuberculosis is usually difficult because the condition can mimic tumors. Fever occurs in 60~85% of patients with tuberculosis, which is one of the important signs of disease activity, and usually resolves by the second week after beginning treatment. However, there are some patients who remain febrile beyond a reasonable treatment period or develop fever during treatment. Such cases raise issues, such as cytokine release from tuberculous granuloma, drug induced fever, drug resistance, and drug malabsorption. We encountered a patient with polypoid colonic tuberculosis who presented with prolonged fever after commencing treatment and became defervescence after a colonoscopic polypectomy. We report this case with a review of the relevant literature.

A Case of Rectal Adenocarcinoid Tumor / 대한소화기내시경학회지

An adenocarcinoid is a mixed tumor comprised of both carcinoid and adenocarcinomatous components that is commonly found in the esophagus, stomach, duodenum, small bowel and appendix, and is also rarely found in the large bowel. A 61 year old male visited our institution because of a change in bowel habitus 3 months prior to the time of his visit. Colonoscopic findings revealed a 2 x 2 cm round smooth surface mass 7 cm from the anal verge, and an endoscopic ultrasonograph revealed a round hypoechoic mass in the submucosal layer. The mass was resected by endoscopic mucosal resection using a cap- fitted endoscope. Pathologic analysis of the mass confirmed that it was a composite tumor comprised of carcinoid and adenocarcinomatous components. To the best of our knowledge, this paper is the first case of rectal adenocarcinoid reported in Korea.

A Case of Angiomyolipoma of the Colon Manifested by Intussusception / 대한소화기내시경학회지

Angiomyolipomas are a form of mesenchymal hamartoma that consists of blood vessels, smooth muscle cells, and mature fat cells. The vast majority of these tumors occur in the kidney. Extrarenal angiomyolipomas are extremely rare and have been reported in the liver, nasal cavity, vagina, spermatic cord, skin, and mediastinum. We report a case of symptomatic angiomyolipoma manifestated caused by colonic intussusception. A 67-year-old male was admitted because of lower abdominal pain that began 10 days prior. Abdominal computed tomography showed intussusception, and colonofiberscopic finding showed a lumen filled with a smooth surfaced pedunculated mass in the left side colon. The patient underwent a partial segmental resection of the sigmoid colon. I report a case of angiomyolipoma that was confirmed by the pathology findings.
