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.

Adrenal Metastasis from Hepatocellular Carcinoma without Intrahepatic Recurrence after Hepatic Resection / 대한소화기학회지

Although the adrenal gland is a common site of metastasis from hepatocellular carcinoma (HCC), adrenal metastases are rarely seen in clinical practice because of its lower metastatic potential compared to the other malignancies. Adrenal metastases usually were detected at the time of diagnosis of primary HCC or simultaneously with intrahepatic recurrence after curative management of HCC. It is very rare that only metastatic HCC is detected without evidence of intrahepatic recurrence. Hereby, we report two cases of adrenal metastasis from HCC without intrahepatic recurrence after hepatic resection.

A Case of B-Lymphoblastic Leukemia/Lymphoma Detected as a Laterally Spreading Tumor / 대한소화기내시경학회지

Acute lymphoblastic leukemia is a cancer of blood cells. It is known as lymphoblastic lymphoma when it involves lymph nodes rather than the blood and bone marrow. The gastrointestinal tract is a predominant site for extra-nodal lymphomas. But, B-lymphoblastic leukemia/lymphoma more frequently presents in the leukemic form than in the lymphomatous form. We herein report a case of B-lymphoblastic leukemia/lymphoma detected as a laterally spreading tumor in the colon. A 54-year-old man was referred to our hospital for removal of multiple colonic polyps. A colonoscopy revealed multiple colonic polyps and several colonic laterally spreading tumors. An esophagogastroduodenoscopy revealed several raised erosive lesions on the fundus and several variable sized sessile polypoid lesions on the duodenum. We diagnosed B-lymphoblastic leukemia/lymphoma following biopsies of the lesions.

The Adequate Induction Dose of Propofol for Conscious Sedation During Esophagogastroduodenoscopy in Persons 60 Years or Older / 대한소화기내시경학회지

BACKGROUND/AIMS: Propofol is an effective sedative drug in endoscopic procedures, but it has potentially serious adverse effects, so close monitoring of the vital signs should be performed during endoscopy. This study was undertaken to determine the adequate induction dose of propofol for safe and effective sedation during esophagogastrodudenoscopy (EGD) in persons 60 years or older. METHODS: Three hundred patients who visited our hospital for EGD were randomly assigned to three groups (A,B and C). An initial induction dose of 0.5 mg/kg, 0.75 mg/kg and 1.0 mg/kg of propofol was allocated to groups A, B and C, respectively. RESULTS: The 0.5 mg/kg, 0.75 mg/kg and, 1 mg/kg dose of propofol were all safe as an initial dose of propofol for achieving sedation during EGD in persons 60 years or older. There was no difference in the total amount of propofol among the three groups. Group C had a significantly shorter induction time and a lower dose was required for an additional injection of propofol without increasing adverse events, as compared to the two other groups. CONCLUSIONS: We suggest that 1 mg/kg of propofol is an effective induction dose for sedation during EGD in persons 60 years or older.
