The most common cause of acute pancreatitis is gallstones. However, idiopathic causes comprise about 10 to 15% of all cases of acute pancreatitis. Biliary sludge is thought to be a cause of idiopathic acute pancreatitis and mainly via obstruction of the common bile duct. Cholesterol polyps of the gallbladder, cholesterolosis and hemobilia can be associated with biliary pain. Fragments of the gallbladder polyps and blood clots can lead to acute pancreatitis in a way similar to that of biliary sludge. Yet it has never been reported that the necrotic tissue of gallbladder cancer can lead to acute pancreatitis. Herein, we report on the case of a 52-year-old man with acute pancreatitis that was caused by the necrotic tissue of gallbladder cancer. The necrotic tissue in the bile duct was revealed on endoscopic retrograde cholangiopancreatography (ERCP). The patient was successfully treated by laparoscopic cholecystectomy along with liver segmentectomy.

Most tumors affecting Vater's ampulla are adenocarcinomas, but a neuroendocrine carcinoma in the ampulla of Vater is extremely rare. The coexistence of these two tumors has been reported in only a few cases. Here, we report a rare case of a collision tumor of the ampulla of Vater with an adenocarcinoma and a large cell neuroendocrine carcinoma.

Pneumatosis cystoides intestinalis (PCI) is an uncommon condition in which submucosal or subserosal gas cysts are present within the bowel wall. We report a case of a 37-year-old man with no medical history. He underwent a colonoscopy for screening purposes, which revealed multiple and variably sized submucosal tumors in the ascending colon. Endoscopic ultrasonographic (EUS) finding showed multiple hyperechogenic regions with distal acoustic shadowing within the submucosa of the ascending colon. A computed tomography scan showed multiple air-filled cystic masses in the ascending colon. EUS appears to be effective for the diagnosis of PCI.

The Korean Society of Gastrointestinal Endoscopy was established in 1976 for academic exchanges between endoscopic specialists. It joined the Korean Academy of Medical Science in 1988 and founded The Gastrointestinal Endoscopy Research Foundation of Korea in 2009 for academics, education, and research on gastrointestinal endoscopy. The Korean Academy of Medical Science rated this academic society 250 out of 275 points, which is equivalent to 91 points when converted to a 100 point scale. Globalization is the recommendation of the Korean Academy of Medical Science. To pursue globalization, this academic society will publish and register English journals on Index Medicus and encourage the use of English during symposiums. Such efforts will allow this academic society to better cooperate and exchange knowledge with academic societies of other countries. Moreover, this academic society must contribute socially by enlightening the public about endoscopy.

Duodenal perforation associated with endoscopic retrograde cholangiopancreatography is very uncommon. However, it usually requires early diagnosis and surgical management. Perforations are commonly caused by endoscopic sphincterotomy, biliary or duodenal stent placement, guidewire-related causes, and endoscopy itself. Perforatioins can follow various clinical courses, and management depends on the cause of the perforation. Among the above causes, guidewire-induced perforation is very rare and related reports and analyses are limited. Herein we describe four cases of guidewire-induced periampullary perforation during endoscopic retrograde cholangiopancreatography, and analyze clinical characteristics and management.

Biliary papillomatosis is a rare disease with a high risk of recurrence and malignant transformation. Therapeutic options include partial hepatectomy, Whipple's procedure and liver transplantation. If there is no surgical option left due to several reasons, local palliative procedures such as biliary stenting and drainage for the treatment of cholestasis are considered, but tumor growth cannot be influenced. Photodynamic therapy might be a new additional, palliative option for patients with biliary papillomatosis who are not eligible for surgery. Benign biliary stricture is a rare complication of photodynamic therapy. We report here a case of a 63-year-old male who developed benign biliary stricture after photodynamic therapy using the photosensitizer photofrin.

Pancreatic cancer is usually unresectable upon diagnosis, and treatment aims to optimize the quality of the patient's life by managing symptoms, and, particularly, by providing adequate pain control. When the pain is refractory to opioids, interventions such as celiac plexus neurolysis (CPN) can be considered. Endoscopic ultrasound (EUS)-guided CPN has been introduced for pancreatic cancer. Reported herein is a case of a 75 year-old man with pancreatic cancer who was treated with opioids due to severe abdominal pain. EUS-guided CPN was performed for pain control, and the opioid administration was discontinued as the pain improved dramatically. However, the patient experienced opioid withdrawal symptoms, including anxiety, insomnia, nausea, and vomiting. Thus, although EUS-guided CPN successfully reduced pain in a patient undergoing such treatment and to whom opioid was administered, opioid administration should not be abruptly discontinued. Rather, the opioid dose should be reduced gradually to avoid drug withdrawal.

The development of total biliary casts is very unusual, and especially in patients who have not undergone liver transplantation. There are only a few reports of total biliary casts in non-liver transplantation patients who have antiphospholipid antibody syndrome, B-cell non-Hodgkin's lymphoma, cholecystectomy or allogenic hematopoietic stem cell transplantation. Here we present the case of a previously well 77-year-old man who developed a total biliary casts without any risk factors and there was no obvious liver insult. The casts were managed endoscopically.

Intussusception occurs when a segment of the bowel invaginates into the lumen of an adjacent distal segment. Intussusception in adults is a rare disease, accounting for only 5% of all cases. Asymptomatic small bowel intussusception in adults without a lead point is usually transient. When the length of the intussusception is less than 3.5 cm, it can be managed conservatively. This case was an asymptomatic small bowel intussusception without a lead point, which was discovered incidentally during an abdominal computed tomography scan. Spontaneous reduction in the intussusception was observed without any complications while maintaining conservative treatment only.

Stercoral perforation of the colon is a rare disease. Yet, in recent times, the number of reported cases has increased because of the growing elderly population. Stercoral perforation of the colon usually occurs in the elderly or bedridden patients with chronic constipation. Stercoral perforation may cause a massive hemorrhage or peritonitis. The prognosis of stercoral perforation is poor, as the reported postoperative mortality is 35~40%. So, early diagnosis and proper treatment are very important for improving survival. However, making an early diagnosis may be difficult because of the nonspecific initial symptoms. We experienced a case of stercoral perforation that was diagnosed by colonoscopy. The defect was in the sigmoid colon, and it was covered with peritoneum. The patient completely recovered after resection and anastomosis of the perforated colon. We report here on this case with a review of the relevant literature.
