RESUMEN
Background/Aims@#This study aimed to evaluate the characteristics of endoscopic retrograde cholangiopancreatography (ERCP) or endoscopic ultrasonography (EUS)-related adverse events (AEs) that eventually lead to medical disputes or claims on medical professional liability. @*Methods@#Medical disputes for ERCP/EUS-related AEs filed in the Korea Medical Dispute Mediation and Arbitration Agency between April 2012 and August 2020 were evaluated using corresponding medical records. AEs were categorized into three sections: procedure-related, sedation-related, and safety-related AEs. @*Results@#Among a total of 34 cases, procedure-related AEs were 26 (76.5%; 12 duodenal perforations, 7 post-ERCP pancreatitis, 5 bleedings, 2 perforations combined with post-ERCP pancreatitis); sedation-related AEs were 5 (14.7%; 4 cardiac arrests, 1 desaturation), and safety-related AEs were 5 (8.8%; 1 follow-up loss for stent removal, 1 asphyxia, 1 fall). Regarding clinical outcomes, 20 (58.8%) were fatal and eventually succumbed to AEs. For the types of medical institutions, 21 cases (61.8%) occurred at tertiary or academic hospitals, and 13 (38.2%) occurred at community hospitals. @*Conclusions@#The ERCP/EUS-related AEs filed in Korea Medical Dispute Mediation and Arbitration Agency showed distinct features: duodenal perforation was the most frequent AE, and clinical outcomes were fatal, resulting in at least more than permanent physical impairment.
RESUMEN
Sedation can resolve anxiety and fear in patients undergoing endoscopy. The use of sedatives has increased in Korea. Appropriate sedation is a state in which the patient feels subjectively comfortable while maintaining the airway reflex for stable spontaneous breathing. The patient should maintain a state of consciousness to the extent that he or she can cooperate with the needs of the medical staff. Despite its benefits, endoscopic sedation has been associated with cardiopulmonary complications. Cardiopulmonary complications are usually temporary. Most patients recover without sequelae. However, they may progress to serious complications, such as cardiovascular collapse. Therefore, it is essential to screen high-risk patients before sedation and reduce complications by meticulous monitoring. Additionally, physicians should be familiar with the management of emergencies. The first Korean clinical practice guideline for endoscopic sedation was developed based on previous worldwide guidelines for endoscopic sedation using an adaptation process. The guideline consists of nine recommendations based on a critical review of currently available data and expert consensus when the guideline was drafted. These guidelines should provide clinicians, nurses, medical school students, and policy makers with information on how to perform endoscopic sedation with minimal risk.

RESUMEN
Enteropathy-type T-cell lymphoma (ETL) or enteropathy-associated T-cell lymphoma is a very rare malignant intestinal tumor. ETL is usually diagnosed by surgery. Endoscopic findings of ETL are not well known, and there are few reports of findings from endoscopy that has been performed only using white light. Additionally, there are no definite treatment guidelines for ETL. Therefore, we report a case of ETL diagnosed by enteroscopy with imaging-enhanced endoscopy and also review recently developed treatment options.

BACKGROUND/AIMS: Narrow band imaging (NBI) is a new technique that uses optical filters for imaging of mucosal morphology. The aim of this study was to correlate findings of NBI with magnifying colonoscopy and histology for prediction of neoplastic colorectal lesion. METHODS: Between September 2005 and December 2007, 107 colon polyps from 68 patients were detected by conventional colonoscopy and subsequently evaluated by NBI with magnifying colonoscopy and analyzed for a pit pattern and a capillary pattern. More analysis was done regarding thickness and irregularity of capillary features. RESULTS: Pit pattern with NBI magnification to discriminate between neoplastic and non-neoplastic lesions had a sensitivity of 88.9% and a specificity of 87.5%; capillary pattern yielded test performance characteristics of 91.9% and 87.5%. In respect of capillary thickness, invisible capillaries were found significantly more often in hyperplastic lesions. All thick capillaries were found in neoplastic polyps, and found significantly more often in carcinomas with submucosal massive invasion (sm-m) (p<0.01). In respect of capillary irregularity, invisible capillaries were found significantly more often in hyperplasic lesions, and severely irregular capillaries were found significantly more often in sm-m lesions (p<0.01). CONCLUSIONS: Observation of capillary thickness and irregularity by NBI magnification is useful for correlating histological grade with carcinoma, especially with depth of submucosal invasion.

BACKGROUND/AIMS: Endoscopic variceal obliteration (EVO), endoscopic variceal ligation (EVL), and balloon-occluded retrograde transvenous obliteration (BRTO) are used to manage gastric variceal bleeding. We compared the re-bleeding rates and survival times of these modalities. METHODS: The study enrolled 103 patients with suspected gastric variceal bleeding between July 2001 and May 2009. For the management of gastric variceal bleeding, 52 patients underwent EVO; 36, EVL; and 15, BRTO. We evaluated their laboratory results and vital signs, and calculated the Child score, Child classification, and Model for End-stage Liver Disease score. Rebleeding was defined as new-onset hematemesis, hematochezia, melena, or endoscopically proven bleeding. Time-to-rebleeding and survival time were examined by Kaplan-Meyer analysis. A value of p<0.05 indicated statistical significance. RESULTS: There were no significant differences in baseline characteristics among the three groups. The overall follow-up period averaged 65.13 months. During follow-up, rebleeding occurred in 17 patients (11 EVO, 5 EVL, and 1 BRTO). The times-to-rebleeding were 63.59, 75.79, and 51.41 months for EVO, EVL, and BRTO, respectively, and did not differ significantly (p=0.515). The median survival times were 77.42, 70.14, and 42.79 months, respectively, and also were not different significantly (p=0.978). CONCLUSIONS: There were no significant differences in the time-to-rebleeding or survival time among EVO, EVL, and BRTO. Further prospective, large-scale studies are needed.

Unknown primary tumor is not an unusual phenomenon. It has been reported that patients with primary unknown cancer constitute 0.5~3.3% of all cancer patients. The most common site of the detected cancer was the lymph node. The locations of the lymph node were cervical, supraclavicular, axillary and inguinal regions. Squamous cell carncer at a metastatic site is found in only approximately 5% of all patients with unknown primary tumors. Especially, squamous cell cancer detected only in mediastinal or hilar lymph nodes is quite rare. We report one case of Metastatic squamous cell cancer of the mediastinum with unknown primary tumor, in which a metastatic survey has not yieled any evidence of further disease. The pathologic finding was representative of squamous cell cancer. A chemotherapy was performed based on the advanced lung cancer for the treatment without surgical approach.

A 29-year-old male patient was admitted due to his general weakness and poor oral intake for several months. He was diagnosed as having Crohn disease 16 years ago and total colectomy was performed 10 years ago. On the 3rd day after admission, gross hematuria and sudden hemoptysis combined with diffuse infiltration were noted on chest X-ray. His symptoms and the diffusely increased lung opacities improved with administering high-dose steroid therapy. Later, anti-GBM antibody was found to be positive on the laboratory findings. We report here on a rare case of Goodpsture syndrome combined with prolonged Crohn disease along with a review of literature.

To investigate psychopathology and executive functions of attention deficit hyperactivity disorder (ADHD) children according to intelligence level, this study included 197 ADHD children who visited the outpatient department of neuropsychiatry of YeungNam University Medical Center, from July 2000 to June 2002. The children were divided into groups based on their intelligence levels. They were compared by the Personality Inventory for Children (PIC), Conncers' Continuous Performence Test (CPT), and Wisconsin Card Sorting Test (WCST). There were significant differences in PIC, on the subscales of verbal development, socialization and autism. In the CPT, there was no significant difference. In the WCST, there were significant differences in the total number of errors, the number of perseverative errors, the number of completed categories and the number of trials needed to complete the first category. Considering these results, the intelligence level of ADHD children is related to their disabilities and behavioral symptoms. Executive functions such as abstract thinking, categorization, working memory and flexibility had significant relationship to the intelligence levels of ADHD children. Therefore, the intelligence level of children with ADHD influences the higher executive functions of regulating attention and information processing rather than attentional functions and capacity alone.

The 64-year-old female patient with cough and intermittent hemoptysis of six months duration visited our hospital. On chest computed tomography, a small, ovoid, 1.3cm sized and well enhanced lesion was detected on the distal trachea. Two multiple lobulated lesions on the sigmoid and transverse colon were revealed on the colonoscopy. The histological findings showed small and medium sized lymphocytes infiltration, CD20 and CD79a positive staining and multiple lymphoepithelial lesions on the distal trachea and colon tissues. Herein, a case of primary MALT lymphoma, with involvement of the trachea and colon, which was treated with rituximab (CD20 anti-monoclonal antibody), cyclophosphamide, adriamycin, vincristine and prednisolone (CHOP regimen), is reported.

Pulmonary sequestration is a very rare congenital malformation in which a mass of pulmonary tissue is detached from the normal lung and receives its blood supply from a systemic artery. It may be clinically asymptomatic or it has a wide spectrum of various clinical manifestations. The clinical therapeutic approach is to resect the sequestered lobe to prevent frequent complication such as infection. The arterial embolization of feeding artery is a new technique and a less invasive treatment than conventional surgical removal. We have experienced a 17- year-old male with pulmonary sequestration whose complaints were pain in left lower chest. He was diagnosed by computed tomography and aortography and successfully treated with embolization of feeding artery. We report a case of pulmonary sequestration treated with arterial embolization instead of surgery.
