Endoscopic Transpapillary Gallbladder Stenting for Acute Cholecystitis in a Patient with Metastatic Pancreatic Cancer / 대한내과학회지

Percutaneous transhepatic gallbladder drainage is an effective treatment for acute cholecystitis in poor surgical candidates. Endoscopic gallbladder drainage procedures, such as endoscopic ultrasound-guided gallbladder drainage, endoscopic gallbladder stenting, and endoscopic naso-gallbladder drainage, have been used as alternative treatments for acute cholecystitis. These procedures are associated with increased patient comfort and physiologic drainage. We report a case of endoscopic gallbladder stenting for acute cholecystitis in a 62-year-old male undergoing chemotherapy for metastatic pancreatic cancer. After endoscopic gallbladder stenting, the patient’s acute cholecystitis resolved and he was able to undergo scheduled chemotherapy. The inserted double-pigtail plastic stent will be left in situ permanently. The choice of drainage modality for acute cholecystitis will generally be based on resources, patient preferences, local expertise, and clinical context.

Primary Lymphoma of Pancreatic Mucosa-Associated Lymphoid Tissue (MALT) / 대한내과학회지

Primary lymphoma of pancreatic mucosa-associated lymphoid tissue (MALT) is extremely rare. Initial suspicion of primary pancreatic lymphoma is hampered by its low incidence. However, it should always be included in a differential diagnosis of pancreatic mass with unusual features, because an accurate diagnosis can avoid unnecessary surgical intervention. A 70-year-old woman presented with melena associated with a mass on the pancreatic head. Endoscopic ultrasonography-guided core-needle biopsy of the pancreatic mass revealed MALT lymphoma. The patient is currently undergoing radiation therapy. We present a case of primary lymphoma of the pancreatic MALT with a review of the literature.

Colonic Intramucosal Cancer in the Interposed Colon Treated with Endoscopic Mucosal Resection: A Case Report and Review of Literature

Colon interposition is a surgical procedure used for maintenance of luminal conduit after esophagectomy. Although epithelial neoplasia, such as adenoma and adenocarcinoma, may develop in the interposed colon, there are only few case reports on the condition. Due to the rarity of this condition, there is no definite consensus on recommending screening endoscopy for the early detection of neoplasia in the interposed colons. Here, we report a case of intramucosal adenocarcinoma in an interposed colon. Initial endoscopic resection for this tumor failed to accomplish complete resection. A subsequent endoscopic resection was performed 1 month later and complete resection was achieved. Based on our experience and recommendation on screening endoscopy for gastric cancer in Korea, we suggest that regular screening esophagogastroduodenoscopies should be performed following esophagectomy to detect early neoplasia in the stomach and interposed colon and avoid adverse results induced by delayed detection.

Stage 1A Pancreatic Cancer Initially Manifesting as Clinical Acute Pancreatitis / 대한내과학회지

Pancreatic cancer has a poor prognosis due to the difficulty of early diagnosis. Observation is recommended for early diagnosis of pancreatic cancer in elderly patients with risk factors such as newly diagnosed diabetes and chronic pancreatitis. A 66-year-old male suffered from acute pancreatitis of uncertain etiology. Initial pancreatic imaging showed a main pancreatic duct stricture at the pancreas body/tail junction and minimal duct dilatation without a visible mass. Eight months later, however, pancreatic imaging revealed a pancreatic mass at the previous stricture site with progression of the upstream duct dilation. The patient underwent distal pancreatectomy, and a pathologic examination showed stage 1A pancreatic cancer with a predominantly intraductal spreading pattern. We report a case of stage 1A pancreatic cancer that initially manifested as acute obstructive pancreatitis, which enabled early diagnosis of pancreatic cancer.
