The risk of complications associated with endoscopic procedures, including bleeding and perforation, tends to increase due to the magnification of the therapeutic endoscopic spectrum. In cases of duodenal perforation, surgical closure is the treatment of choice; however, there have been some cases in which the nonsurgical treatment of an iatrogenic duodenal perforation during an endoscopic procedure was effected via endoscopic clipping closure. Here, we report two cases of successful endoscopic clipping closure of an iatrogenic duodenal perforation occur ring during a duodenoscopy insertion for ERCP and endoscopic mucosal resection for the treatment of duodenal adenoma.

A Killian-Jamieson diverticulum (KJD) is an unfamillar and unusual cervical esophageal diverticulum. This diverticulum originates on the anterolateral aspect of the esophagus through the Killian-Jamieson's area that is formed between cricopharyngeal muscle and the lateral to longitudinal esophageal muscle. Recently, we experienced a patient who was found outpouching lesion on lateral side of left esophagus on the duodenoscopy. Then, a barium esophagography performed and in left lateral position demonstrated a left-sided diverticulum with a frontal projection, highly suggestive of a KJD. There are two ways of surgical approach to manage the KJD. First is external approach, another one is endoscopic approach. In common, external approach has been recommended for the treatment of KJD because of concern of nerve injury. We present a case of KJD that underwent external approach and sternocleidomastoid muscle flap in the management of KJD.

The recent development of endoscopic retrograde cholangiopancreatography (ERCP) now permits the collection of pure human pancreatic secretions via duodenoscopic cannulation. Study objectives are evaluation of exocrine pancreatic function and analysis of pure pancreatic juice collected by use of ERCP technique in subjects without pancreatic disease. From March to July 1993, we performed ERCP and collection of pure pancreatic juice in 10 patients without evidence of pancreatic disease. (continue...)

Ectopic pancreas is commonly located at stomach, duodenum and jejunum. It is a relatively rare entity and is usually of no clinical importance which especially is a very rare source of massive upper gastrointestinal bleeding. We have recently experienced a case of an ectopic pancreas in the second portion of the duodenum which was proven to be a source of massive gastrointestinal bleeding by duodenoscopy and was confirmed by surgical exploration.

Patients with pancreatic cancer frequently suffer from both biliary and duodenal obstruction. For such patients, both biliary and duodenal self-expandable metal stent placement is necessary to palliate their symptoms, but it was difficult to cross two metal stents. Recently, endoscopic ultrasonography-guided choledochoduodenostomy (EUS-CDS) was reported to be effective for patients with an inaccessible papilla. We report two cases of pancreatic cancer with both biliary and duodenal obstructions treated successfully with simultaneous duodenal metal stent placement and EUS-CDS. The first case was a 74-year-old man with pancreatic cancer. Duodenoscopy revealed that papilla had been invaded with tumor and duodenography showed severe stenosis in the horizontal portion. After a duodenal uncovered metal stent was placed across the duodenal stricture, EUS-CDS was performed. The second case was a 63-year-old man who previously had a covered metal stent placed for malignant biliary obstruction. After removing the previously placed metal stent, EUS-CDS was performed. Then, a duodenal covered metal stent was placed across the duodenal stenosis. Both patients could tolerate a regular diet and did not suffer from stent occlusion. EUS-CDS combined with duodenal metal stent placement may be an ideal treatment strategy in patients with pancreatic cancer with both duodenal and biliary malignant obstruction.

Heterotopic pancreas, a developmental anomaly uncommonly noted both during operations and autopsies, is usually described in each instance as an incidental finding, Precise diagnosis can be made more often now by endoscopy. Rarely heterotopic pancreas can cause intra-abdominal hemorrhage or obstruction. We experienced a very rare case in which aberrant pancreas located at the Ampulla of Vater was found to be the cause of partial obstruction of the comon bile duct. Diagnosis was done by duodenoscopy and biopsy. So, we report a case of heterotopic pancreas at the Ampulla of Vater diagnosed by endoscopy with a review of relevant literatures.

Intramural duodenal hematoma (IDH) is a rare complication of pancreatitis. We report a unique case of IDH caused by acute gallstone pancreatitis in a 37-year-old man. The patient presented with hematemesis and sudden exacerbation of upper abdominal pancreatic pain. An abdominal computed tomography scan showed an intramural hyperdense hematoma and symmetric thickening of the duodenal wall along with peripancreatic inflammation and gallbladder stones. A duodenoscopy also revealed a bloody edematous duodenal wall with a narrow lumen due to IDH. The patient recovered fully from the acute pancreatitis and IDH without pancreaticoduodenectomy using conservative management and a subsequent cholecystectomy.

Santorinicele denotes a focal cystic dilatation of the terminal dorsal pancreatic duct at the minor papilla. Santorinicele results from a combination of obstruction and weakness of the distal dorsal ductal wall. This anomaly has been found in patients with pancreas divisum and recurrent acute pancreatitis. We recently experienced a typical case of santorinicele associated with pancreas divisum incidentally found in a 71-year-old woman presented with acute cholecystitis. At duodenoscopy, the minor papilla was plumped out and bulged into the duodenal lumen after contrast injection. Dorsal pancreatography showed a cystic dilatation at the terminal portion of the dorsal duct and upstream dilatation. In this patient, previous pancreatic-type pain and pancreatitis are thought to be related to this anomaly.

The incidence of retroperitoneal abscess with fistula formation after acute pancreatitis is rare, but the mortality rate for patients with this condition is very high. The standard treatment for this condition has been surgical removal and drainage. However, recent studies have shown that percutaneous catheter drainage or noninvasive endoscopic abscess drainage with using endoscopic ultrasonography is effective and safe for the treatment of pancreatic and peripancreatic abscess. A retroperitoneal abscess with duodenal fistula that developed after acute pancreas and its endoscopic treatment has never been reported on in Korea. We experienced a 45-year-old man who had been treated for acute pancreatitis at other hospital, and he was then referred to our hospital and diagnosed as having a retroperitoneal abscess with fistula, which communicated with the third portion of duodenum, as assessed by abdominal CT and duodenoscopy. So we treated him with endoscopic double-pigtailed stent insertion through the fistulous tract and we drained the abscess. Endoscopic drainage may be a suitable alternative for the management of the retroperitoneal abscess with fistula that develops after acute pancreatitis.
