Autoimmune pancreatitis is now considered to be a systemic fibroinflammatory disease that can involve multiple organs. As it is associated with IgG4-positive plasma cells by an autoimmune mechanism, extrapancreatic organs as well as the pancreas could be affected with a lymphoplasmacytic infiltrate. The proximal bile duct, the salivary gland, the retroperitoneum and the kidney are well known to be involved with, but less is known about the involvement of hollow viscus which is pathologically associated with autoimmune pancreatitis. We report here on a case of gastric involvement in a 53-year-old man with autoimmune pancreatitis.

Metallic stents are being widely used in patients with a malignant obstruction of the biliary tract. The advent of metallic stents was heralded as a solution to the problem of plastic stent occlusion. Metallic stents prolong stent patency by lowering occlusion rates, but they may malfunction for several reasons, including occlusion from tumor ingrowth or migration after the procedure. Distal migration or impaction of metallic stents against the duodenal wall may cause severe complications, including duodenal obstruction, perforation and acute upper gastrointestinal bleeding. Several techniques have been developed to manage distal migration of a biliary metallic stent and remove the malfunctioning stent endoscopically. We report on a 43-year-old male who underwent endoscopic palliative biliary drainage because of obstructive pancreatic head cancer. We transected the distal end of the metallic stent using an argon plasma coagulator, treating the duodenal obstruction without any complications.

Biloma is a rare disorder, and is defined as an abnormal extrahepatic or intrahepatic collection of bile within a defined capsular space. The common causes of biloma are iatrogenic and trauma. Spontaneous biloma, especially caused by pancreatic cancer, is very rare. An 86-year-old man was admitted with abdominal pain and fever. The patient denied a history of abdominal surgery, endoscopic retrograde cholangiography, or trauma. Abdominal computed tomography demonstrated a huge collection of fluid in the left lobe of the liver, dilatation of the intra and proximal common bile duct, and a heterogeneous enhancing mass in the pancreatic head portion. Percutaneous drainage under ultrasound guidance was performed, and the fluid analysis was compatible with biloma. A plastic stent was endoscopically inserted into the common bile duct to treat continuous drainage of the fluid despite percutaneous drainage. We report a case of biloma developed spontaneously in a patient with pancreatic cancer and successfully treated by endoscopic biliary stenting.

The incidence of acute cholecystitis complicating endoscopic retrograde Cholangiopancreatography (ERCP) is rarely reported at 0.2% but is usually associated with a cystic duct obstruction caused by gallstones, gallbladder polyps, or cancer. However, acute cholecystitis with a gallbladder perforation after ERCP without a history of cystic duct obstruction can develop very rarely and has not yet been reported in Korea. We report a case of acute cholecystitis with gallbladder perforation and aggravation of a pancreatic pseudocyst after diagnostic ERCP in a man with a pancreatic cystic lesion. He has been successfully cured using only percutaneous transhepatic gallbladder drainage and antibiotics with no surgery.

Colonic pseudo-obstruction, which is characterized by repetitive episodes or continuous symptoms and signs of a bowel obstruction, is a rare disease that results in colorectal dilatation without any obstructing lesions. Cases with neuropathic chronic colonic pseudo-obstruction have rarely been reported in Korea. We report a case of neuropathic colonic pseudo-obstruction, which results in decreased number of interstitial cells of Cajal and hypoganglionosis, in a 50-year-old man with chronic constipation accompanied by megacolon.

Anaphylaxis is a potentially life-threatening allergic reaction, presenting with various clinical symptoms. The most common etiologies of anaphylactic reactions include allergic responses to food, medications, latex, and Hymenoptera stings. In its classic form, anaphylaxis typically involves the cutaneous, respiratory and cardiovascular systems. Gastrointestinal symptoms, including nausea, vomiting, diarrhea and cramping abdominal pain, can occur transiently but mucosal lesions are rarely detected. We recently experienced a case of ischemic colitis presenting with hematochezia after bee venom-induced anaphylactic shock. To the best of our knowledge, this is the first case in Korea. We report the case with a review of the literature.

Malignant colonic obstruction can lead an emergency operation for decompression, and this can cause post-operative complications due to poor bowel preparation. Self-expandable metal stent (SEMS) insertion is useful for avoiding an emergency operation and unnecessary complications. However, SEMS insertion for dual malignant colonic obstructions is very rare. We report here on a case of two SEMS that were inserted in dual malignant colonic obstructions caused by synchronous colon cancer. A 66-year-old man visited our hospital due to abdominal distension. Sigmoidoscopy and an abdominopelvic computerized tomographic (CT) scan revealed synchronous colon cancer at the splenic flexure and distal descending colon with dual obstruction. The initial SEMS insertion on the descending colon was not effective for decompression due to the proximal obstruction. After the second SEMS insertion on the splenic flexure through the first stent, all the signs and symptoms due to obstruction disappeared. SEMS insertion is considered to be useful for treating dual malignant colonic obstruction caused synchronous colon cancer.

Gastric volvulus is torsion of the stomach axis accompanied by obstruction and/or strangulation. It is a very rare condition, but it is considered a clinical emergency when it occurs acutely. Acute gastric volvulus requires an early diagnosis and prompt surgical treatment because a delayed diagnosis may lead to gastric obstruction, ischemia and necrosis. We experienced two cases of acute gastric volvulus due to diaphragmatic hernia and the patients were successfully treated with surgery. Here, we report on these two cases with the review of the reported literature on 26 adult cases of gastric volvulus in South Korea.

Methylene blue (MB) based chromoendoscopy has been used for more than a decade to increase detection rates of specialized intestinal metaplasia, dysplasia, and esophageal adenocarcinoma. It is also used to detect anastomotic leakage after an operation. A 67-year-old man with no previous medical problems had complaints of jaundice and weight loss for 2 months. He was diagnosed with a Klatskin tumor and was referred to our hospital. An initial esophagogastroduodenoscopy (EGD) was performed before the operation. No abnormality was observed in the esophagus. MB solution was infused via an L-tube to check for leakage in the anastomosis. Subepithelial hemorrhagic and edematous mucosal changes with friability and a bluish mucosal discoloration were noted 2 days later from the mid to lower esophagus on EGD. Nine months later, an EGD revealed an unremarkable esophageal mucosa. MB solution is considered safe; however, a large volume or high concentration of MB solution might be harmful.

Foreign body ingestion is common in children, but magnet ingestion is rare. Ingestion of one magnet does not creat a serious problem; however, ingesting multiple magnet can lead to hazardous complications such as pressure necrosis, intestinal perforation, fistula formation, obstruction and intestinal volvulus. Most cases with complications after multiple magnet ingestion require surgical intervention. We report a case of a fistula following the ingestion of seven small, flat and round magnets that were removed successfully by endoscopic submucosal dissection without surgery.
