A 65-year-old woman was diagnosed with an 8 cm large common bile duct stone and multiple stones in both intrahepatic ducts because of abnormal liver function tests. After a multidisciplinary approach, surgical removal was considered, and primary closure after laparoscopic removal of the common bile duct stone was performed. The patient recovered without complications and was discharged on the fourth postoperative day. Endoscopic removal of common bile duct stones is the standard treatment, but surgical removal through laparoscopic common bile duct exploration is also a safe and effective treatment method for such huge gallstones.

The guidewire is an essential accessory in ERCP. Although rare, guidewires can cause complications, such as subcapsular hepatic hematoma, perforation, knotting, fracture, and impaction, during ERCP. This report describes a guidewire impaction during the endoscopic treatment of a patient with symptomatic chronic pancreatitis. The methods used to treat guidewire impaction are not well known. In the present case, the impacted guidewire was retrieved by inserting another guidewire and dilating the space adjacent to it. Endoscopists should check for the free movement of the guidewire before stent deployment. Additionally, it is important to ask for help from experienced senior staff to overcome any challenges during the procedure. In conclusion, endoscopists should be aware of the possibility of a guidewire impaction during ERCP.

Undifferentiated pancreatic carcinoma with osteoclast-like giant cells (UC-OGC) is uncommon, accounting for only 1% of all pancreatic carcinomas. We report a case of a 39-year-old man with undifferentiated pancreatic carcinoma with osteoclast-like giant cells who underwent successful surgical resection and chemotherapy.

Choledocholithiasis carries a risk of developing biliary obstruction, acute cholangitis, and pancreatitis. Therefore, removal is recommended even in asymptomatic patients. Endoscopic retrograde cholangiopancreatography (ERCP) is regarded as the standard of treatment for choledocholithiasis nowadays. However, ERCP can accompany severe complications such as bleeding, ERCP-associated pancreatitis, cholangitis, and perforations. It is important for endoscopists to know how to remove choledocholithiasis effectively while minimizing adverse events. In this review, we will go over the technical aspects and various accessories to effectively remove choledocholithiasis.

Gastric outlet obstruction is a major symptom in patients with advanced pancreatic cancer. Endoscopic intervention is often challenging in severe strictures because the guidewire cannot pass beyond the stricture. Sometimes, the air itself cannot pass beyond the stricture, which can result in a severely distended stomach. Such a stomach is vulnerable to excessive air insertion or mechanical stress during endoscopic procedures, and endoscopists may encounter a higher rate of complications. Gastric perforation is rare but could be fatal. However, endoscopic management can show a favorable result if the perforation is noticed early. The authors report a case of the perforation of a gastric tear during duodenal stent insertion in a patient with a gastric outlet obstruction.

Acute pancreatitis is a sudden inflammatory disease that could be developed into a fatal condition. Traditional dogma was to rest the pancreas by fasting. However, evidence shows the benefits of early enteral feeding resulting in a shorter hospital stay, improved mortality, multi-organ failure, systemic infections, and the need for operative interventions. Clinicians should encourage enteral feeding as soon as possible even in severe acute pancreatitis if there are no contraindications. An immediate solid diet could be attempted. Regarding tube feeding, the nasojejunal tube did not show superiority to the nasogastric tube. Different formulas and probiotics need more investigation. Guidelines are against using prophylactic antibiotics, but Korean centers still report overuse of antibiotics. However, there is still a debate about using prophylactic antibiotics in severe acute pancreatitis. Broad-spectrum antibiotics should be initiated when an infection is suspected. In conclusion, enteral nutritional support and optimal use of antibiotics are the keys to the management of acute pancreatitis.

Accessory spleens are common congenital anatomic variations that are usually asymptomatic. On the other hand, they can be clinically significant if complicated by hemorrhage, torsion, or infarction. This paper describes a case of an infarcted accessory spleen in a 30-year-old male who presented with abdominal pain. Abdominal CT and MRI revealed an isolated mass, 4.5 cm in size, in the perisplenic area. An infarcted accessory spleen was suspected. The patient underwent laparoscopic accessory splenectomy. Histopathology identified the mass as splenic tissue that had undergone ischemic necrosis. A definitive diagnosis of an infarcted accessory spleen was made, and the patient was discharged on day 5 after surgery symptom-free.
