Intussusception Caused by Colon Cancer in Pregnancy / 대한소화기학회지

Intussusception is a common in pediatric age group. But it is rare in adults. And intussusception caused by tumor account for 1% of bowel obstructions in adult. Intussusception is an extremely rare cause of abdominal pain in pregnancy. In particular, cases of Intussusception due to colorectal cancer during pregnancy have never been reported in Korea. Our patient is a 34 years old woman who presented at 14 weeks of her second pregnancy. She presented with right lower abdominal discomfort and intermittent palpable mass which was usually spontaneously resolved. In the MRI study, pathologic asymmetric wall thickening was still noted and ileocolic intussusception was noted, and in colonoscopy, there was ulcerofungating mass around ileocecal valve which may be a leading point of intussusception. Biopsy was done. Pathologic finding was poorly differentiated adenocarcinoma. Under the patient agreement, we performed dilatation and curettage and laparoscopic right hemicolectomy and lymph node dissection. Now she is receiving a FOLFOX chemotherapy.

Ascending Colon Variceal Bleeding in Cirrhotic Patient with Emergent Endoscopic Variceal Obturation with N-butyl-2-cyanoacrylate / 대한소화기학회지

Ectopic varices are rare among patients with portal hypertension, especially in the ascending colon. It is difficult to evaluate massive lower gastrointestinal bleeding in patients with liver cirrhosis by colonoscopy due to hemodynamic instability and poor bowel preparation. In Korea, there has only been one case report about ascending colon variceal bleeding, in which hemostasis was performed by venous coil embolization. We report another rare case of ascending colon variceal bleeding in a patient with alcoholic cirrhosis, who was successfully treated via two sessions of N-butyl-2-cyanoacrylate injection through colonoscopy. This case suggests that the careful endoscopic approach and hemostasis with glue injection might be an option for treating massive bleeding in the lower gastrointestinal varix.

Portal Vein Cannulation During Endoscopic Retrograde Cholangiopancreatography / 대한내과학회지

A 68-year-old woman was admitted to our hospital with obstructive jaundice. Abdominal CT scan demonstrated a mass at the head of the pancreas. The patient was diagnosed as having obstructive jaundice caused by pancreatic cancer. We tried to relieve the bile duct obstruction by ERCP (endoscopic retrograde cholangiopancreatography). After several cannulation attempts, we thought that we had achieved deep cannulation of the bile duct and tried to place a biliary plastic stent. During ERCP, however, we noticed massive air in the portal venous system, indicating possible cannulation of the portal vein. The procedure was terminated immediately and abdominal computed tomography revealed air in the portal venous system. Fortunately, there were no subsequent complications. The air in the portal vein had disappeared, ascertained by CT scan taken 5 days later. The patient underwent surgical resection for pancreatic cancer. Isolated portal vein cannulation per se does not usually result in mortality or serious morbidity.

A Large Neuroendocrine Tumor of the Major Duodenal Papilla Removed by Endoscopic Papillectomy / 대한내과학회지

Neuroendocrine tumors (NET) of the major duodenal papilla are rare and the natural history of this disease is not clear. We experienced a case in a 31-year-old male. Duodenoscopy revealed an enlarged major duodenal papilla with central umbilication and nodularity. Endoscopic ultrasonography (EUS) demonstrated a 3-cm hypoechoic mass that was confined to the submucosa. A biopsy led to the diagnosis of a grade 1 NET. The patient refused surgery, so we performed an endoscopic papillectomy. The tumor was removed completely. The resected specimen confirmed the diagnosis of a well-differentiated NET and all resection margins were negative. Surgical resection is currently considered to be the gold standard for the treatment of a large NET of the major duodenal papilla; however, endoscopic resection is a possible treatment modality for patients at high surgical risk or who are reluctant to undergo surgery.

Clinical Usefulness of Bile Cytology Obtained from Biliary Drainage Tube for Diagnosing Cholangiocarcinoma / 대한소화기학회지

BACKGROUND/AIMS: Biliary drainage is performed in many patients with cholangiocarcinoma (CCA) to relieve obstructive jaundice. For those who have undergone biliary drainage, bile cytology can be easily performed since the access is already achieved. This study aims to determine the clinical usefulness of bile cytology for the diagnosis of CCA and to evaluate factors affecting its diagnostic yield. METHODS: A total of 766 consecutive patients with CCA underwent bile cytology via endoscopic nasobiliary drainage or percutaneous transhepatic biliary drainage from January 2000 to June 2012. Data were collected by retrospectively reviewing the medical records. We evaluated the diagnostic yield of bile cytology with/without other sampling methods including brush cytology and endobiliary forcep biopsy, and the optimal number of repeated bile sampling. Several factors affecting diagnostic yield were then analyzed. RESULTS: The sensitivity of bile cytology, endobiliary forceps biopsy, and a combination of both sampling methods were 24.7% (189/766), 74.4% (259/348), and 77.9% (271/348), respectively. The cumulative positive rate of bile sampling increased from 40.7% (77/189) at first sampling to 93.1% (176/189) at third sampling. On multivariate analysis, factors associated with positive bile cytology were perihilar tumor location, intraductal growing tumor type, tumor extent > or =20 mm, poorly differentiated grade tumor, and three or more samplings. CONCLUSIONS: Although bile cytology itself has a low sensitivity in diagnosing CCA, it has an additive role when combined with endobiliary forceps biopsy. Due to the relative ease and low cost, bile cytology can be considered a reasonable complementary diagnostic tool for diagnosing CCA.

Retroperitoneal Hemorrhage after Thrombolysis in ST Elevation Myocardial Infarction / 영남의대학술지

Bleeding is the most common and serious complication of thrombolysis in ST elevation myocardial infarction. Most bleeding cases are associated with an intervention or operation, but spontaneous bleeding such as gastro-intestinal bleeding or intracranial hemorrhage can happen. This is a report on the case of a 76-year-old female patient with retroperitoneal hemorrhage due to spontaneous right colic artery branch bleeding after thrombolysis in ST elevation myocardial infarction.
