Eggerthella Lenta Bacteremia after Appendectomy in a Healthy Patient / 대한내과학회지

Eggerthella lenta (E. lenta) has been reported to cause bacteremia in patients with gastrointestinal tract disorders or malignancies and in immunocompromised patients. Cases of E. lenta have been increasing with the recent development of testing equipment. The mortality rate due to E. lenta bacteremia is high. The authors report a case of E. lenta bacteremia in an immunocompetent patient.

Small Bowel Obstruction Caused by Aloe vera Bezoars: A Case Report / 대한소화기학회지

Small bowel obstruction is a clinical condition commonly caused by postoperative adhesion, volvulus, intussusceptions, and hernia. Small bowel obstruction due to bezoars is clinically uncommon, accounting for approximately 2-4% of all obstructions. Computed tomography (CT) is a useful method in diagnosing the cause of small bowel obstruction. However, small bowel obstruction caused by bezoars may not be detected by an abdominal CT examination. Herein, we report a rare case of small bowel obstruction by Aloe vera bezoars, which were undetected by an abdominal CT. Phytobezoars should be included in the differential diagnosis of small bowel obstruction in patients with predisposing factors, such as excessive consumption of high-fiber food and diabetes.

Cerebral venous thrombosis in a patient with Crohn's disease

Patients with inflammatory bowel disease (IBD) have an elevated risk of venous thromboembolism compared with the general population. The most common sites of venous thromboembolism in IBD patients are the deep veins of the legs, the pulmonary system, and portal and mesenteric veins. However, cerebral venous thrombosis is rarely associated with IBD. This report describes a case of cerebral venous thrombosis in a patient with Crohn's disease. A 17-year-old girl, diagnosed 4 years earlier with Crohn's disease, presented with headache and vomiting. Magnetic resonance imaging of the brain with venography showed venous thrombosis in the cortical veins, superior sagittal sinus, right transverse sinus, and right internal jugular vein. The patient immediately started anticoagulation therapy with intravenous heparin infusion followed by daily oral rivaroxaban 10 mg. Follow-up imaging after 2 weeks showed resolution of the thrombosis, with recanalization of the cortical veins, superior sagittal sinus, right transverse sinus, and right internal jugular vein. She continued rivaroxaban therapy for 6 months, and remained well, without neurologic sequelae. A high level of concern for cerebral venous thrombosis may be important when treating active IBD patients, because anticoagulation treatment can prevent fatal complications.

A Case of Cavernous Lymphangioma of the Small Bowel Mesentery / 대한소화기학회지

Lymphangioma is a benign vascular lesion with characteristics of subepithelial tumor which can proliferate in the lymphatic system. Lymphangioma of the small-bowel mesentery is rare, having been reported in less than 2% of all lymphangiomas. Lymphangioma does not require any specific treatment because it is absolutely a benign tumor. However, surgical exploration is rarely required for cases with disease-related symptoms or complications, or for those misdiagnosed as a malignant lesion. We recently experienced a case of mesenteric cavernous lymphangomas in a 53-year-old female who was misdiagnosed as having a liposarcoma. The final diagnosis was confirmed by a pathologic examination of the specimen that was obtained via laparoscopic exploration. Herein, we report a very rare case of mesenteric cavernous lymphangioma along with a brief review of relevant literature.

Fatal Small Bowel Bleeding with very Low Risk Gastrointestinal Stromal Tumor in Jejunum / 이화의대지

Gastrointestinal stromal tumor (GIST) is the most common mesenchymal neoplasm of the gastrointestinal (GI) tract. These tumors are frequently small, asymptomatic and found incidentally. GI bleeding is a common complication of these tumors, but small sized, very low risk GIST rarely complicated with fatal bleeding. In this report, we describe a 42-year-old woman with a jejunal GIST accompanied by severe GI bleeding. She presented with melena and an angiographic embolization was performed for a jejunal mass with bleeding. However, rebleeding was suspected after an angiographic embolization and an emergent segmental resection for the bleeding mass was performed. She was finally diagnosed as a 1.8 cm sized very low risk GIST in jejunum. In conclusion, physician should consider that even very low risk GIST can be the cause of GI bleeding when there is severe bleeding.
