A Case of Endoscopically Treated Laryngopharyngitis Resulting from Clinostomum complanatum Infection / 대한소화기학회지

A 46-year-old woman visited our hospital presenting throat pain and globus sensation. The symptoms occurred seven days after eating raw perch and mullet. An endoscopy under sedation showed a fluke―with an approximate length of 4.8 mm and width of 1.5 mm―on the left aryepiglottic fold, with active motility on the mucosa. It was extracted from the larynx using biopsy forceps and was identified as Clinostomum complanatum. To the best of our knowledge, this is the second reported case of human infection with Clinostomum complanatum diagnosed and treated by an endoscopy in Korea. Endoscopy is a useful tool in the diagnosis and treatment of patients at risk for parasitic infections complaining of throat pain.

A Case of Suspected Intrahepatic Bile Duct Perforation after Direct Peroral Cholangioscopy / 대한췌담도학회지

Direct peroral cholangioscopy (POC) which permits direct visualization of the biliary tree has recently gained widespread clinical use for diagnosis and treatment of various pancreatobiliary diseases. But, there is currently little reliable data on evaluating the complications of POC. POC is associated with complications such as pancreatitis, cholangitis, hemorrhage, rarely air embolism, and ductal perforation. The incidence of complication during POC is 2.9-12%. However, pneumoperitoneum due to intrahepatic bile duct perforation after POC has not yet been reported in Korea. We report a case of pneumoperitoneum after POC which has been successfully managed with endoscopic nasobiliary drainage and antibiotics.

A Case of Endoscopic Removal of a Giant Appendicolith Combined with Stump Appendicitis

Stump appendicitis is an acute inflammation of the residual appendix and is a rare complication after appendectomy. The physician should be aware of the possibility of stump appendicitis in patients with right lower abdominal pain after appendectomy so that delayed diagnosis and treatment can be prevented. Stump appendicitis is usually treated by surgical resection, and endoscopic treatment has not been reported previously. A 48-year-old man who had undergone appendectomy 35 years earlier presented to the hospital because of right lower quadrant discomfort. A computed tomography scan showed a large stone in the residual appendix. Colonoscopic findings revealed a large, smooth, protruding lesion at the cecum with a stone inside the appendiceal orifice. Endoscopic removal after incision of the appendiceal orifice was performed successfully.

A Case of Enteritis Cystica Profunda in the Ampulla of Vater Mimicking Choledochocele

Enteritis cystica profunda is a very rare disease in which a mucin-filled cystic space is surrounded partially with nonneoplastic columnar epithelium in the submucosa of the small intestine. Most of the cases are accompanied by intestinal diseases, and the disease usually occurs in the jejunum and the ileum and there has been no report of a case that occurred in the ampulla of Vater. A 58-year-old healthy female patient without any particular symptom visited the hospital to get additional examination for a mass found on the ampulla of Vater by accident. In esophagogastroduodenoscopy, a cystic mass showing a positive pillow sign was found on the ampulla of Vater. Endoscopic retrogradecholangiopancreatography was conducted as choledochocele was suspected, but no abnormality was found in the biliary system. In endoscopic ultrasonography, multiseptated cystic structures were detected in the submucosal layer of the duodenum. The lesion was resected completely through endoscopic snare polypectomy and the case was histologically diagnosed as enteritis cystica profunda.

A Case of Signet-ring Cell Carcinoma of the Ampulla of Vater / 대한소화기내시경학회지

Signet-ring cell carcinoma of the ampulla of Vater is so rare that only 16 cases have been reported. Here we report a case of a 47-year-old man with signet-ring cell carcinoma in the ampulla of Vater. The patient was hospitalized for right upper quadrant abdominal pain and jaundice which had developed 10 days prior. Computed tomography (CT) and ultrasonography (US) revealed dilatation of the common bile duct and the intrahepatic bile duct. On duodenoscopy, a bulging mass with an irregular margin in the major papilla was noted. Histologic findings showed a signet-ring cell carcinoma. Surgical resection was not done because lymph node metastasis was noted during the operation. Hence, conservative treatment including chemotherapy and bile drainage was done.

Clinical Characteristics and Gestational Complications Associated with Acute Hepatitis A in Pregnancy / 대한소화기학회지

BACKGROUND/AIMS: Acute hepatitis A was recently significant increased among women with gestational age in Korea. However, the clinical course and gestational complications have not been fully elucidated in pregnant patients with acute hepatitis A. We evaluated the clinical impact of acute HAV infection in pregnancy. METHODS: Twelve pregnant women out of 85 female patients with acute hepatitis A during 6 years were retrospectively reviewed. RESULTS: The median age of the pregnant group was 26.5 years old. The number of patient with acute hepatitis A were 5 cases in the 1st trimester, 3 cases in the 2nd and 4 cases in the 3rd. 4 cases had significant gestational complications. One case experienced the abortion in 1st trimester and one fetal distress was noted in 3rd trimester. The latter case was delivered of a low birth weight infant (2,390 g) caused by premature rupture of membrane in 36 weeks of gestational age. Other two cases experienced premature contraction and they had been required tocolytic treatment. But, all mothers featured full recovery from HAV infection. Except one aborted fetus and one premature birth, Newborn babies were not affected by maternal hepatitis A. CONCLUSIONS: Acute HAV infection during pregnancy may be associated with the risk of gestational complications. HAV serology and vaccination for women with gestation age should be considered at high prevalence area of acute hepatitis A.
