Acute Cholecystitis After a Colonoscopy

Acute cholecystitis after a colonoscopy is a rare event, and only eight documented cases are reported in the literature. A 35-year-old male underwent a screening colonoscopy. There was a 5-mm sessile polyp in the sigmoid colon, which was removed by using a hot snare polypectomy. Forty-eight hours after the colonoscopy, the patient visited our emergency department with epigastric pain and fever. Based on the clinical findings, laboratory data and radiologic imaging, our diagnosis was acute cholecystitis. Because no previous cases of this type have been reported to date in Korea, we publish the details of our patients who presented with a postcolonoscopy complication diagnosed as acute cholecystitis.

A Case of Intrahepatic Cholangiocarcinoma Associated with Type IV Choledochal Cyst / 대한소화기학회지

Anomalous union of the pancreaticobiliary duct (AUPBD) is a congenital anomaly that is defined as a junction of the bile duct and pancreatic duct outside the duodenal wall. This anomaly results in a loss of normal sphincteric mechanisms at the pancreaticobiliary junction. As a result, regurgitation of pancreatic juice into the biliary system develops and causes choledochal cysts, choledocholithiasis, cholangitis, pancreatitis and malignancy of the biliary tract. Gallbladder cancer or common bile duct cancer associated with AUPBD and choledochal cysts have been frequently reported. But, intrahepatic cholangiocarcinoma associated with this condition has been only rarely reported. Here, we report a case of intrahepatic cholangiocarcinoma associated with AUPBD and choledochal cyst.

A Case of Gastrointestinal Amyloidosis as a Complication of Crohn's Disease / 대한소화기내시경학회지

Amyloidosis is a disorder resulting from extracellular deposition of insoluble fibrils and causes dysfunction in many organs. Secondary amyloidosis, caused by chronic infectious and inflammatory disease, may involve the kidneys, liver, bone marrow and gastrointestinal tract. Involvement of the gastrointestinal tract is common and presents various symptoms according to location. Amyloidosis as a complication of Crohn's disease is a rare but serious complication that may worsen the prognosis. We report a case of gastrointestinal amyloidosis in a 59-year-old male patient with Crohn's disease that was diagnosed with an endoscopic forceps biopsy of the stomach, terminal ileum and colon.

A Case of Clonorchiasis with Focal Intrahepatic Duct Dilatation Mimicking an Intrahepatic Cholangiocarcinoma

Biliary strictures can be caused by various diseases. Intrahepatic duct (IHD) strictures are usually related to IHD stones and cholangitis. However, focal IHD strictures without IHD stones often create diagnostic problems. Parasitic diseases such as clonorchiasis can be a rare cause of an IHD stricture. Human clonorchiasis (Clonorchis sinensis infection) is an endemic parasitic disease in Eastern Asia, including Korea, and patients acquire the infestation by eating raw fish. On radiological examinations, clonorchiasis shows typically diffuse, minimal, or mild dilatation of the small IHD, particularly in the periphery, without dilatation of the extrahepatic duct. However, diagnosis of clonorchiasis can sometimes be difficult when radiological changes are atypical. We report a case of focal left IHD dilatation caused by clonorchiasis that was confused with a malignancy.

Two Cases of Sigmoid Volvulus Treated by Emergency Colonoscopic Reduction Procedure / 대한소화기내시경학회지

A volvulus of the colon is a twisting of a redundant segment of the colon at its narrow mesentery. A sigmoid volvulus is the most common type. This disorder may spontaneously reduce and recur as a chronic problem. However, it more frequently becomes acute as a result of an obstruction, which can lead to strangulation and gangrene with a high mortality if not treated promptly. Colonoscopic reduction and decompression is the preferred initial treatment for patients with a sigmoid volvulus who show no signs of bowel strangulation, which may be the cause of the high mortality associated with emergency surgery. We experienced 2 cases of a sigmoid volvulus in a 44-year-old female and a 51-year-old male. The sigmoid volvulus was diagnosed by simple abdominal film and treated successfully by an emergency colonoscopic reduction. We report our experience on the use of colonoscopy to treat sigmoid volvulus with a reviews of the relevant literlature.

A Case of Gastritis Cystica Profunda Associated with Tubular Adenoma / 대한소화기내시경학회지

Gastritis cystica profunda (GCP) is a rare disease in which mature glandular epithelium extends into the muscularis mucosae or below. GCP lesions mainly develop at the gastroenterostomy stomas. These lesions show malignant histologic features such as metaplastic and even dysplastic alteration, however they usually exhibit benign behavior. We report a case of a patient with GCP who had not previously undergone gastric surgery. A 63-year-old woman visited our hospital for anorexia and epigastric discomfort. The esophagogastroduodenoscopy revealed two polyps on the anterior wall of the greater curvature, antrum. The polyps were removed by snare polypectomy and the histology findings showed the character of a tubular adenoma and a hyperplastic polyp with an associated GCP.

A Case of Cecal Colon Cancer Causing Intussusception and Synchronous Sigmoid Colon Cancer / 대한소화기내시경학회지

The incidence of intussusception in adults is quite low. A preoperative diagnosis was quite difficult due to the atypical clinical features, but the success rate of preoperative diagnosis of intussusception has improved with the advances in abdominal US and CT. However, the value of colonoscopy in making a preoperative diagnosis is unclear. The incidence of multiple primary cancer of the colon and rectum can vary widely. We report a case of intussusception in a patient who had synchronous cecal and sigmoid colonic cancer. A 71-year-old man was visited our hospital for diarrhea and general weakness. The abdominal US and CT revealed a mass lesion in the cecal area. Preoperative colonoscopy confirmed the lesion to be cecal cancer with a synchronous sigmoid colon cancer. In conclusion, the rarity of these synchronous cancers may result in a misdiagnosis. Therefore, a preoperative colonoscopy or postoperative colonoscopy might be useful.
