Endoscopic retrograde cholangiopancreatography (ERCP) is an invasive procedure carrying potential complication such as pancreatitis, hemorrhage, perforation and cholangitis. Most of those complications are mild and usually need a short additional hospitalization periods. Perforation, however, often requires surgical intervention and in this case, the rate of mortality is up to 10%. Prompt diagnosis and proper management are key determinants for successful outcome. For this, endoscopist should be aware of possibility of perforation before procedure especially in high risk patients with altered anatomy such as prior Billroth II or Roux-en-Y anastomosis. After diagnosis of perforation, multidisciplinary approach involving medical, surgical and radiologic interventional subspecialties, is essential. Usually, surgical treatment is needed for type I free wall perforation and medical and endoscopic treatments are recommended for type II-IV perforation. Recently, several anecdotal studies reported successful endoscopic treatment using new devices for type I duodenal wall perforation but it is not warranted that endoscopic treatments can substitute the surgical intervention.

Plastic biliary stents are commonly used during endoscopic retrograde cholangiopancreatography. Main indication for biliary stenting is benign or malignant obstruction. Plastic stents can be used as an escape route in patients with large common bile duct stones to provide drainage until definitive treatment. But, stent occlusion is the main disadvantage, limiting their patency to around 3 months, after which replacement is recommended. A biliary stent can act as a nidus for the biliary stone formation leading to stent-stone complex after long-term stent placement. This report was a case of a large stent-stone complex after plastic stent placement for 4 years. The stent-stone complex was successfully removed by mechanical lithotripsy and ballon catheter. In all other cases where plastic stents are placed into the common bile duct we should keep in mind that stents can act as nidus for stone formation, as all foreign bodies do.

Pseudoaneurysm is one of life-threatening complications of chronic or acute pancreatitis. It can lead to massive bleeding into the abdominal cavity, the retroperitoneum, or the gastrointestinal tract. Hemosuccus pancreaticus, meaning hemorrhage through the pancreatic duct into the duodenum is an important diagnostic clue suggesting the presence of pancreatic pseudoaneurysm. A 74-year-old man presented with hematochezia and active bleeding from the ampulla of Vater was noted on upper endoscopy. Abdominal computed tomography scan demonstrated a nodular enhancing lesion within the pancreatic duct. Celiac trunk angiography also showed a nodular enhancing lesion suggesting pseudoaneurysm in the pancreas. However, due to the difficulty of identifying the feeder artery of pseudoaneurysm by selective angiography, embolization was not feasible. Therefore, distal pancreatectomy was performed and ruptured pseudoaneurysm within the pancreatic duct could be confirmed. Herein, we report a case of hemosuccus pancreaticus due to ruptured intraductal pseudoaneurysm that was successfully treated by surgical management.

Infected walled-off pancreatic necrosis (WOPN) is dangerous complication of acute pancreatitis. Open necrosectomy and post-operative irrigation of necrotic cavity have been conventional treatment for infected pancreatic necrosis, however, recently minimally invasive techniques such as endoscopic necrosectomy has been regarded as preferred treatment method for infected WOPN. Endoscopic necrosectomy provides a targeted approach with a reduction in the systemic inflammatory response and avoidance of wound complications. Non alcohol related Wernicke encephalopathy is rare disease caused by thiamine deficiency due to intravenous feeding, and presented an encephalopathy, oculomotor dysfunction, gait ataxia. We report herein a case of Wernicke encephalopathy after successful endoscopic necrosectomy for infected WOPN.

Adenomyoma is a non-neoplastic lesion that frequently occurs in the gallbladder, but it's rarely found at the ampulla of Vater. When it develops at the ampulla of Vater, it may be mistaken for a periampullary malignancy. A 64-year-old asymptomatic male patient visited to our hospital with abnormal sonogram findings. Abdominal computed tomography and magnetic resonance cholangiopancreatography showed dilatations of common bile duct and main pancreatic duct. However, there was no definite ampullary mass. We performed endoscopic biopsies and endoscopic ultrasonography-guided fine needle aspiration. But the results were negative for malignant cells. Because we could not completely rule out malignancy, pylorus preserving pancreato-duodenectomy was performed. Histologically, hyperplastic components are intermixed with smooth muscle fibers in the subepithelial portion of ampulla of Vater. Awareness of adenomyoma of the ampulla of Vater is very important because of their clinical and endoscopic similarities to ampullary tumors.

The pancreatic cystic lesions are known to be incidentally found up to 10-15% of patients undergoing cross-sectional imaging. And the prevalence of mucinous cystic neoplasm which has malignant potential is known to be up to 25% of all pancreatic cystic neoplasm in South Korea. The symptoms included abdominal pain, palpable mass, weight loss, loss of appetite, jaundice, asymptomatic and etc. However, spontaneous rupture of pancreatic mucinous cystadenocarcinoma (MCAC) is an extremely rare complication. Here we report a case of spontaneous rupture of pancreatic MCAC in a 72-year-old male with review of the literature. To the best of our knowledge, this is the first ruptured case of pancreatic MCAC in male patient.

Endoscopic papillectomy (EP) has been considered to be a less invasive, alternative therapy to surgery for ampullary adenoma. However, complication rates after EP could not be ignored, when compared to endoscopic resection for gastrointestinal lesions. Among them, the prevalence of postpapillectomy pancreatitis is higher in EP than ERCP. The prophylactic placement of a pancreatic stent has been reported to decrease the risk of pancreatitis after EP. However, since pancreatic stent placement after EP is not always successful, various novel techniques have been developed to ensure reliable stent placement. Despite the recent advances in EP, a prospective, randomized, controlled study with a larger number of patients is needed to assess the efficacy of pancreatic stent placement to prevent pancreatitis.

Acute pancreatitis is one of the potentially life-threatening diseases with a wide spectrum of severity. The estimated mortality rate for all patients with acute pancreatitis is approximately 5%. Severe pancreatitis often takes a clinical course with two overlapping phases, an early and a late phase, with two peaks of mortality. According to the revised Atlanta classification system, acute pancreatitis can be divided into mild, moderately severe, or severe. It is important to identify patients with potentially severe acute pancreatitis who require aggressive early treatment. It is believed that intravenous fluid resuscitation is an important variable for improved outcomes in acute pancreatitis. Most guidelines encourage targeting fluid resuscitation toward correcting hypotension, correcting hemoconcentration, and maintaining adequate urine output. In this review article, I would like to discuss the assessment of severity and fluid administration in acute pancreatitis.

Acute recurrent pancreatitis (ARP) refers to a clinical condition characterized by repeated episodes of acute pancreatitis, diagnosed retrospectively after at least the second episode of acute pancreatitis. It is still controversial that acute pancreatitis can progress to chronic pancreatitis, and acute, acute recurrent and chronic pancreatitis is a continuum of disease. The causes of ARP can be divided into mechanical, hereditary and metabolic factor. Despite recent advances in diagnostic technologies, the etiology of ARP still remains unknown in up to 30% of cases. Especially in recurrent episode of idiopathic pancreatitis, a clinician should be considered not only the common causes of ARP, such as gallstone disease and alcohol, but also rare causes of ARP. The common causes of 'idiopathic' recurrent pancreatitis are microlithiasis, sludge, sphincter of oddi dysfunction, pancreas divisum and hereditary pancreatitis. Various treatment options, such as cholecystectomy, endoscopic sphincterotomy, medical and surgery can be applied according to the identified etiology of ARP and treatment should be individualized. Currently, endoscopic treatment is increasingly performed and served as a curative treatment strategy. The medical treatment can be an option in microlithiasis and sludge, but it has limitation in terms of systemic side effect, efficacy and lack of long term outcome. Endoscopic treatment should be considered in selected patients with identifiable cause, and post procedural complication should be considered before endoscopic treatment.

There are increasing number of cases of serum amylase and lipase levels being examined as part of health screening, but the clinical significance of these amylase and lipase levels is unclear. When the clinicians encounter patients with elevated pancreatic enzymes, the most common causes such as acute pancreatitis, hepatic or renal dysfunction should be ruled out first by thorough history taking, physical examination, and laboratory tests. Further tests including abdominal ultrasonography or computed tomography, lipid profile, tumor marker, isoenzyme, and calculation of amylase-to-creatinine clearance ratio or polyethylene glycol precipitation test should be performed to exclude other causes. If the pancreatic enzymes are continuously elevated through repeated tests without any apparent etiology, the diagnosis is made with chronic non-pathological pancreatic hyperenzymemia (CNPH). Magnetic resonance cholangiopancreatography is very useful and important modality for the patients with CNPH but the clinical significance of magnetic resonance cholangiopancreatography with secretin stimulation is still unclear. They can be evaluated through endoscopic ultrasonography with preference but it is less suitable for follow-up. Individualized approaches should be made after considering the need for active treatment or periodic follow-up for the benign pancreatic diseases associated with CNPH. It is difficult to conclude until more long-term data are reported because there are only limited number of researches and consensus on the range of tests to be performed for diagnosis, clinical significance of benign findings and end of follow-up in patients with CNPH.
