Villous adenoma of the bile ducts: a case report and a review of the reported cases in Korea

Villous adenomas are benign epithelial lesions with malignant potential which can occur at any site in the gastrointestinal tract. They are usually encountered in the rectum and colon, less frequently in the small bowel and very rarely in the biliary trees. Nine cases of bile duct villous adenomas have been reported in the literature. However, 4 cases of bile duct villous adenomas have been reported in the Korean literature. Recently, we experienced a case of villous adenoma in the common hepatic duct in a 77-year-old man presenting with obstructive jaundice in which preoperative histologic diagnosis of villous adenoma played a critical role in managing this patient. Herein, we present a case report of bile duct villous adenoma and a review of the reported cases in Korea to help define and manage this rare disease entity in the bile ducts. In addition, confusing nomenclature of bile duct adenomas is discussed.

Rectal Endometriosis: A Case Report of with a Clinical Analysis of Other Cases Reported in Related Korean Literature / 대한소화기내시경학회지

Endometriosis is the abnormal growth of endometrial tissue outside the uterine cavity. Involvement of the gastrointestinal tract is seen in 3~34% of patients affected by this condition. Although the commonest sites involved are the sigmoid colon and rectum, only 4 cases have been reported in Korea. The most frequent symptoms are lower abdominal and pelvic pain typically worsening at the time of menstruation. Bleeding per rectum is uncommon since the mucosa is rarely involved. Endoscopy has not been thought to be helpful in the evaluation of patients with suspected colonic endometriosis. However, endoscopy is often used as the first test in patients with rectal bleeding, excluding malignancy or other sources of bleeding. There are few reports of endoscopic documentation of colorectal endometriosis. A 26 year-old woman having a history of endometriosis with cyclic hematochezia and lower abdominal pain is herein reported. A flexible sigmoidoscopy revealed a protrusion of hyperemic mucosa with a surrounding fold formation on the rectum 8 cm above the anal verge. The subsequent biopsy of the lesion gave rise to a diagnosis of endometriosis.

Two Cases of Emphysematous Cholecystitis / 대한내과학회지

Emphysematous cholecystitis is an uncommon form of acute cholecystitis characterized by the presence of gas within the wall, lumen of the gall bladder or biliary ducts. Clinically it is very similar to ordinary farm. But since the risk of perforation is five times that expected from ordinary cholecystitis, early diagnosis and appropriate surgical treatment are important. We could diagnose these cases by the simple abdomen, abdominal ultrasound and abdominal CT by the presence of air in the lumen and the wall of the gall bladder. Percutaneous trans hepatic gall bladder drainage (PTGBD) for decompression was used because poor general condition of patients and later, we could successfully perform the cholecystectomy without any complication. We presented two cases of emphysematous cholecystitis with review of the relevant literature on the subject.
