A Case of Clonorchiasis Presenting as Common Hepatic Duct Mass / 대한소화기내시경학회지

The liver fluke, Clonorchis sinensis is an important human parasite and is endemic in Eastern Asia including Korea, China, and Japan. Patients acquire the infestation by eating raw or undercooked freshwater fish. Radiologic examinations usually reveal dilated peripheral intrahepatic bile ducts and normal extrahepatic bile duct. The diagnosis of clonorchiasis may sometimes be difficult and a presentation as an obstructive mass at the common hepatic duct is a rare event. Here we report a case of clonorchiasis of 54-year-old woman presented with epigastric pain. Endoscopic retrograde cholangiography revealed a mass at the common hepatic duct with dilatation of the intrahepatic ducts mimicking cholangiocarcinoma. Using an endoscopic basket, muddy, sludge-like materials were extracted through the papillary orifice. We report this case with a review of literatures.

Primary Malignant Fibrous Histiocytoma (MFH) of the Small Bowel Presenting as an Intussusception Causing Small Bowel Obstruction / 대한소화기학회지

Adult intussusception secondary to primary sarcoma is a rare cause of small bowel obstruction. Only a few cases of malignant fibrous histiocytoma (MFH) of small bowel presenting as an intussusception have been reported in the literatures. We report a case of small bowel obstruction associated with jejuno-ileal intussusception caused by MFH. A 75-year-old man was admitted with an one-month history of vomiting and epigastric pain aggravated with meals. He was diagnosed as an jejuno-ileal intussusception based on CT scanning and underwent small bowel resection and anastomosis. Resected specimens revealed a polypoid tumor in the ileum and the histology of the tumor was consistent with MFH.

Endoscopic Removal of a Spoon from the Stomach Using Guidewire / 대한소화기내시경학회지

Foreign body ingestion is a relatively uncommon, but potentially serious condition. Most of gastrointestinal foreign bodies pass spontaneously. But, large objectives are usually lodged in the stomach and cause perforation, bleeding, and obstruction. Therefore, prompt retrieval of lodged foreign bodies are necessary before complications develop. Particularly, in the case of long metallic spoon, there have been no cases of spontaneous passage reported. Therefore, prompt retrieval of a metallic spoon are necessary. A 28-year-old woman with schizophrenia who ingested a long spoon for suicidal attempt was referred to our hospital. Simple abdomen showed a 18 cm sized long, metallic spoon with saw-toothed end placed in the stomach. We removed a spoon by an endoscopic technique and an extraction maneuver using a guidewire and a Magill forceps.

Secondary Esophageal Cancer Originated from Rectal Cancer / 대한소화기내시경학회지

Secondary esophageal carcinoma usually originates from a primary site in either the lung or breast. Only one case of metastatic esophageal cancer with a radiologic evidence that it was originated from the rectal cancer had been reported. We report an unusual case of a 80-year-old man with secondary esophageal carcinoma originated from the rectal cancer. It was diagnosed by histopathologic confirmation using immunohistochemical staining including CK20 and CK7 by comparing the histopathologic findings of surgical specimen of rectal cancer and endoscopic biopsy tissue from the esophagus. To the best of our knowledge, this is the first case of secondary esophageal cancer arising from rectum in Korea.
