Cholecystectomy is the best method for treating gallstone diseases. However, 10%-30% of patients who undergo a cholecystectomy continue to complain of upper abdominal pain, dyspepsia, or jaundice-this is referred to as postcholecystectomy syndrome. Cystic duct stump stones are a troublesome cause of postcholecystectomy syndrome. Conventionally, surgery is mainly performed to remove cystic duct stump stones. However, repeated surgery can cause complications, such as postoperative bleeding, biliary injury, and wound infection. As an alternative method of surgery, endoscopic retrograde cholangiopancreatography is sometimes used to remove cystic duct stump stones, although the success rate is not high due to technical difficulties. Recently, peroral cholangioscopy, which can directly observe the bile duct, has been suggested as an alternative method. We report two cases in which a cystic duct stump stone was successfully removed via a single-operator cholangioscopy, after failure with an endoscopic retrograde cholangiopancreatography.

Cap-assisted endoscopy refers to a procedure in which a short tube made of a polymer (mostly transparent) is attached to the distal tip of the endoscope to enhance its diagnostic and therapeutic capabilities. It is reported to be particularly useful in: (1) minimizing blind spots during screening colonoscopy, (2) providing a constant distance from a lesion for clear visualization during magnifying endoscopy, (3) accurately assessing the size of various gastrointestinal lesions, (4) preventing mucosal injury during foreign body removal, (5) securing adequate workspace in the submucosal space during endoscopic submucosal dissection or third space endoscopy, (6) providing an optimal approach angle to a target, and (7) suctioning mucosal and submucosal tissue with negative pressure for resection or approximation. Here, we review various applications of attachable caps in diagnostic and therapeutic endoscopy and their future implications.

Bezoars are retained concretions of undigested animal or vegetable material that can produce gastrointestinal obstruction, ulceration, and bleeding. Therapeutic options for gastric bezoars include enzyme therapy (papain, cellulase, or acetylcysteine), endoscopic disruption and removal, and surgical removal. Multiple large gastric bezoars generally require conventional surgical management through an upper abdominal incision. With the recent improvement of laparoscopy, a lot of portions of abdominal operations have been performed laparoscopically. We successfully removed multiple large gastric phytobezoars in a 52-year-old female completely through laparoscopy. This supported the feasibility of laparoscopic surgery for patients with gastric bezoars.

Objective : The surgical approach for recurrent pituitary adenoma after trans-sphenoidal approach (TSA) is challenging. We report the outcomes of the endoscopic TSA for recurrent pituitary adenoma after microscopic TSA. Methods : From February 2010 to February 2013, endoscopic TSA was performed for removal of 30 recurrent pituitary adenomas after microscopic TSA. Twenty-seven (90%) patients had a clinically non-functioning pituitary adenoma. Twenty-four (80%) patients suffered from a visual disturbance related to tumor growth. The clinical features and surgical outcomes were retrospectively analyzed for the ophthalmological, endocrinological, and oncological aspects. Results : The mean tumor volume was 11.7 $cm^3$, and gross total resection was achieved in 50% of patients. The volumetric analysis based on the postoperative MR showed that the mean extent of resection rates were 90%. Vision was improved in 19 (79%) of 24 patients with visual symptoms, and endocrinological cure was achieved in all of three functioning pituitary adenomas; however, the post-operative follow-up endocrinological examination revealed a new endocrinological deficit in one patient. Two patients required antibiotics management for post-operative meningitis. Conclusion : The endoscopic TSA can be an effective treatment option for recurrent pituitary adenoma after microscopic TSA with acceptable outcome.

We are reporting a case of esophageal hemangioma, which is a very rare disease with only 24 cases having been reported. A 31-year-old male with dysphagia was shown to have a hemangioma of the upper thoracic esophagus and resection of the lesion cured this problem. Once diagnosed in symptomatic patient, treatment should be instituted because of followings; 1. growth potency to large size, 2. possible complications such as hemorrhage and obstruction, and 3. exclusion diagnosis of malignancy. Surgery is the treatment of choice due to its effectiveness and safety, but endoscopic removal may be possible for small tumors and those on a pedicle.

The laryngeal foreign bodies are not common among the foreign bodies in the air and food passage, however, it would cause fatal airway obstruction without performing immediate endoscopic removal or emergency tracheostomy procedure. It is our intent to report three cases of laryngeal foreign bodies, and to discuss diagnostic procedures, preventive measures and management of this problems.

Background: The accidental swallowing of foreign body is a common problem in the children. Ingested foreign bodies may be managed by endoscopy, observation, or surgery. So we analyzed the methods of removal, type, location and complications of foreign bodies. Materials and Methods: This report reviewed 37 cases of ingested foreign body in the gastrointestinal tract at the Department of Pediatrics, Yeungnam University Hospital between January 1997 and April 2001. Results: The age ranged from 8 months to 8 years. The most prevalent age group was between 1 year and 2 years of age(19%). The male to female ratio was 2.1:1 with 25 male and 12 female patients. The type of foreign bodies were coins in 20 cases(54%), nail in 4 cases(11%), key in 4 cases(11%), pin in 2 cases(5.5%), necklace in 2 cases(5.5%) and others. The locations of foreign bodies were upper esophagus in 12 cases(32.5%), lower esophagus in 4 cases(10.8%), stomach in 16 cases(43.2%), small bowel in 5 cases(13.5%). 4. Presenting symptoms were variable with asymptomatic(59.4%), vomiting(19.0%), epigastric pain(8.1%), dysphagia(5.4%) and others. The methods for removal of foreign bodies included 20 cases of endoscopic removal(54.0%). 3 cases of spontaneous removal(8.1%) and there was no surgical removal. 14 cases(37.9%) did not confirmed removal of foreign body because of no revisit of our hospital. Endoscopic finding of patients were normal(15 cases), ulceration(2 cases), erosion(1 case), inflammation(1 case), mucosal scratch(1 case). Conclusion: It appears that the endoscopic approach is the preferable method for the removal of upper gastrointestinal foreign bodies in the children.

There are a lot of dental emergency situations and accidental aspiration or ingestion of a dental instrument is one of the common accidents in dental practice especially on disabied or pediatric patient with negative behavior. Most of ingested foreign bodies pass through the gastrointestinal tract spontaneously, but some of them (about 20%) need endoscopic or surgical removal. This is a case of an accident during the treatment of a 18 months male patient with caries of anterior deciduous teeth. During the treatment, the gauze was used by waterproofing instead of a rubber dam. #4 round bur (approximately 2.2cm long) which was put on the tray was cling to the gauze and the bur was fell into the patient's throat. The bur was 2.2cm long and very sharp so it could not be passed spontaneously through the pylorus, so we tried to remove the bur by esophagogastroduodenoscopy. Endoscopic removal of foreign bodies in the upper gastrointestinal tract is an effective and safe procedure.

Purpose: Foreign body (FB) ingestion is common in children, and button battery (BB) ingestion has been increasing in recent years. This study was to identify factors related to outcomes of FB ingestion, particularly BBs in the stomach. We evaluated whether the current recommendations are appropriate and aimed to suggest indications for endoscopic removal of BB in the stomach in young children. Methods: We investigated patient age, shape, size, location of FBs, spontaneous passage time and resulting complications among 76 children. We observed types, size, location of BB and outcomes, and analyzed their associations with complications. Results: Coins and BB were the two most common FBs. Their shapes and sizes were not associated with the spontaneous passage time. Size, spontaneous passage time, and age were also not associated with any specific complications. For BB ingestion, all 5 cases with lithium batteries (${\geq}1.5cm$, 3 V) presented moderate to major complications in the esophagus and stomach without any symptoms, even when the batteries were in the stomach and beyond the duodenum, while no complications were noted in 7 cases with alkaline batteries (<1.5 cm, 1.5 V) (p=0.001). All endoscopies were conducted within 24 hours after ingestion. Conclusion: The type and voltage of the battery should be considered when determining whether endoscopy is required to remove a BB in the stomach. For lithium battery ingestion in young children, urgent endoscopic removal might be important in order to prevent complications, even if the child is asymptomatic and the battery is smaller than 2 cm.
