A Case of Gallbladder Actinomycosis / 감염과화학요법

Actinomycosis is a chronic suppurative and granulomatous disease, characterized by abscess formation, tissue fibrosis, and draining sinuses. Actinomycosis of the gallbladder is very rare and has not yet been reported in Korea. We report a case of actinomycosis of the gallbladder in an 80- year-old women with history of cholelithiasis for 3 years, preoperatively misidentified as gallbladder cancer. Histologic section of the gallbladder showed Gram-positive branching bacilli compatible with actinomyces. After cholecystectomy, the patient received intravenous ampicillin for 4 days, followed by amoxicillin for 4 months thereafter.

A Case of Mucin-hypersecreting Biliary Papillomatosis: Including Review of Korean Literatures / 대한소화기내시경학회지

The mucin-hypersecreting bile duct tumor is rare and its clinical, radiologic, and pathologic features are not well known. We report the case of mucin-hypersecreting biliary papillomatosis with malignant transformation including review of 11 korean literatures. A 65-year-old female was admitted to our hospital with fever, chills, and right upper quadrant pain. A CT scan showed marked dilatation of left intrahepatic duct with intraductal filling defects. During endoscopic retrograde cholangiograpy, mucin from the ampulla was observed and dilated common bile duct with multiple amorphous filling defects was noted. Cholangioscopy revealed muliple coral-like mucosal papillary projections with large amount of mucin in the left intrahepatic ducts. The patient underwent left lobectomy, and the biopsy revealed intraductal papillary adenocarcinoma in the background of papillary adenoma.

Intraductal Papillary Mucinous Tumor of the Pancreas Still Resectable 5 Years after Diagnosis / 대한소화기내시경학회지

Intraductal papillary mucinous tumor (IPMT) of the pancreas is a spectrum of conditions ranging from benign to malignant. It is known that the biologic behavior of IPMT is slower and less aggressive than that of pancreatic ductal carcinoma. We report a case of IPMT of pancreas resected 5 years after diagnosis. The carcinoma remained localized without evident stromal invasion or lymph node metastasis with the background of adenoma, suggesting a adenomacarcinoma sequence. This is a case report that may be helpful to study the natural history of IPMT, particularly slow progression of IPMT.

Three Cases of Gallstone Ileus / 대한소화기내시경학회지

Gallstone ileus is a mechanical obstruction caused by the impaction of one or more gallstones within the lumen of any part of the gastrointestinal tract. Gallstone ileus is frequently proceeded by an episode of acute cholecystitis. The resulting inflammation and adhesions facilitate the erosion of the offending gallstone through the gallbladder wall forming a cholecystoenteric fistula and allowing the passage of the gallstone. Fifty five-year-old, 71-year-old, and 74-year-old female patients were admitted to the Asan Medical Center for nausea, vomiting, and nonspecific abdominal pain. Erect abdominal plain film revealed several moderately dilated loops of small bowel with air fluid levels. Computed tomography showed the classic triad of findings of gallstone ileus. Dilated loops of small bowel, air in the biliary tree and an ectopic stone in the ileum were demonstrated. These impacted stones were removed by surgical intervention.
