Two Cases of Adrenal Abscesses Following Histoacryl(R) (N-butyl-2-cyanocrylate) Injection

We report two cases of adrenal abscesses that occurred following a Histoacryl(R) (N-butyl-2-cyanocrylate) injection for variceal bleeding. Patients had been diagnosed with alcoholic liver cirrhosis and gastric varices bleeding and received a Histoacryl(R) injection for the variceal bleeding. Patients had fever and abdominal tenderness and were diagnosed with an adrenal abscess at 2 months following the Histoacryl(R) injection. One patient received open drainage and the other underwent percutaneous drainage. When a patient has previously been injected with Histoacryl(R) for the treatment of variceal bleeding and presents with fever, an evaluation for an unusual complication such as adrenal abscess is recommended.

A Case of Right Diaphragmatic Hernia of Sigmoid Colon Showed by Colonoscopy / 대한소화기내시경학회지

A 53-year-old man complained of constipation and abdominal pain including the right flank area for three days. He had suffered multiple rib and clavicular fractures on the right side 10 years earlier. Colonoscopy was performed to assess the constipation, which showed a twisted constricted lumen in the sigmoid colon or descending colon. Passing through it, the saccular dilated bowel wall demonstrated edematous, erythematous changes in the mucosa with a purplish color and necrosis. The proximal part of the saccular lumen also showed a twisted stricture with necrotic materials. The abdominal CT showed subsegmental atelectasis in the right lung, right pleural effusion and a diaphragmatic hernia of the colon. In addition, multiple dilated bowel loops were observed in the abdomen. The patient underwent emergency surgery with a segmental resection of the sigmoid colon. We report this case of delayed traumatic right diaphragmatic hernia of the sigmoid colon with strangulation, which is extremely rare and was revealed by colonoscopy.

A Case of Primary Jejunal Malignant Lymphoma Associated with Nodular Lymphoid Hyperplasia / 대한소화기내시경학회지

Nodular lymphoid hyperplasia is a reaction of the intestinal lymphatic tissue to specific inflammatory stimuli and may be probably of no clinical significance, but it may evolve to primary gastrointestinal lymphoma in more severe cases. Recently, several cases of nodular lymphoid hyperplasia complicated by primary gastrointestinal lymphoma have been reported, and which suggested that nodular lymphoid hyperplasia could not be considered as simple benign colon disease any more. We also experienced a case of primary jejunal malignant lymphoma associated with nodular lymphoid hyperplasia, and report this case with a brief review of relevant literatures.

A Case of Giant Cavernous Hemangioma of Transverse Colon Associated with Hematochezia / 대한소화기내시경학회지

Gastrointestinal hemangiomas are not common and congenital lesion. Intestinal bleeding is the most common symptom of it. Hemangiomas were classified with capillary, cavernous and mixed type. Cavernous hemangioma is most common. Colonic cavernous hemangioma is rare and are usually arising in the sigmoid colon or/and rectum. Transverse colonic cavernous hemangioma are very rare. Gastrointestinal hemangioma is commonly developed in childhood and in young adults. Fifty eight-year-old man who complained of hematochezia was admitted. Physical examination was unremarkable. Stool occult blood was positive. Abdominal computerized tomography show normal finding. Colonoscopic examination showed giant and bluish-purple colored vascular malformation, 15 cm in length with tough bleeding, on the transverse colon. The patient underwent segmental resection of transverse colon for confirmatory diagnosis and treatment. The final pathologic diagnosis of the resection lesion was cavernous hemangioma of the transverse colon. We report a case of giant hemangioma of the transverse colon associated with hematochezia, with review of relevant literature.

Antibiotics Associated Hemorrhagic Colitis: A report of two cases / 대한소화기내시경학회지

Antibiotics related colitis is a well recognized disease entity which in its severest form may result in pseudomembranous colitis, whereas in another form, acute hemorrhagic colitis without pseudomembrane, related to the use of penicillin-type antibiotics is rarely reported. The clinical features of hemorrhagic colitis associated with antibiotics was characterized that the bloody diarrhea, often with abdominal cramping pain begins 2~7 days after starting the antibiotics and rapidly recovered after its withdrawal. Pathogenesis of this disease is not entirely clear. It has been believed that right-sided hemorrhagic colitis is one of the main forms of colitis associated with antibiotics, especially ampicillin derivatives or cephalosporin, but recent reports presented left-sided colitis. We experienced 2 cases of hemorrhagic colitis developed on the left colon after the introduction of quinolone.

Change of Clinical Patterns and Significance of Endoscopy in Gastric Outlet Obstruction / 대한소화기내시경학회지

BACKGROUND/AIMS: The causes of gastric outlet obstruction (GOO) have changed from peptic ulcer disease (PUD) to malignant diseases in recent years. The aims of this study are to determine the relative incidence of malignany and other causative diseases, and to consider therapeutic and diagnostic usefulness of endoscopy. METHODS: 95 patients with GOO who diagnosed by radiologic and endoscopic examination or surgery were reviewed by causative diseases, clinical features, endoscopic findings and outcome of treatment. RESULTS: 1) The mean age was 57.5 years (M:F=2.4:1). 2) The causative diseases were gastric or duodenal malignancy (56.8%), complication of PUD (39.2%), and biliary and pancreatic disease (4.2%). 3) Malignancy was diagnosed by upper gastrointestinal (UGI) endoscopy in 95.8%; obstruction by complication of PUD was detected by endoscopy in 100%. 4) The most common endoscopic type of malignancy was Borrman type 3 (84.8%) and the most common benign lesions were duodenal or pyloric ulcer (94.5%). 5) The managements of malignancy were operation (53.5%), endoscopic stenting (18.5%), and conservative treatment (38.8%). The complications of PUD were treated by anti-ulcer medication (85.3%), endoscopic dilatation (4.8%) and operation (13.6%). CONCLUSIONS: The main causes of GOO are changed to malignancy in recent 5 years. Endoscopy is useful to detect the various causes of GOO, and necessary procedure to decide the method of their management.
