The World Health Organization (WHO) declared the worldwide pandemic of Coronavirus disease-2019 (COVID-19) On March 11, 2020, just three months after the first outbreak of COVID-19 caused by Severe Acute Respiratory Syndrome Coronavirus 2 in China in December 2019. COVID-19 is a contagious disease that can affect anyone, anytime, anywhere, and has had a huge impact on our lives, including social, economic, educational, and cultural life. In this paper, I would like to explore the issues related to COVID-19 in the gastroenterology and share the experiences of domestic and overseas gastroenterologists, and ultimately to seek ways to effectively prepare for and cope with the pandemic era of COVID-19.

The most common cause of esophageal foreign bodies in adults is meat in Western countries and fish bones in Asian countries, including Korea. Although most ingested foreign bodies pass spontaneously through the esophagus without any clinical sequelae, some sharp foreign bodies, such as fish bones embedded in the esophagus, require treatment. Endoscopic management is the first choice in the treatment of esophageal foreign bodies because it is quite safe and effective. Major complications occur as a result of esophageal perforation; in particular, sharp foreign bodies, such as fish bones, are more likely to cause perforation. Complications include mediastinitis, paraesophageal abscess, pneumomediastinum, subcutaneous emphysema, pneumothorax, tracheoesophagal fistula, aortoesophageal fistula, aspiration, and asphyxia. Unnecessary delays should be avoided in endoscopic intervention for esophageal foreign bodies to prevent complications.

BACKGROUND/AIMS: Inflammatory bowel disease (IBD), including Crohn's disease (CD) and ulcerative colitis (UC), has been reported to have various ophthalmologic manifestations. The aim of this study was to evaluate the prevalence of ophthalmologic manifestations associated with IBD in Korea. METHODS: Sixty-one patients were examined between May 2013 and October 2014. We performed complete ophthalmologic examinations. RESULTS: Findings included 36 patients with CD and 25 with UC. The mean age of the patients was 34±16 years and disease duration was 45.3±23.9 months. Ophthalmologic manifestations were positive in 44 cases. Primary complication was diagnosed in 5 cases, as follows; iritis in 2 cases, episcleritis in one case, iritis with optic neuritis in 1 case, and serous retinal detachment in 1 case, without secondary complications. The most common coincidental complication was dry eye syndrome (DES), in 35 patients (57.4%). The prevalence of DES in the control group was 21.3%. The proportion of DES in patients with IBD was significantly higher than in the control group (P=0.002). CONCLUSIONS: Ophthalmologic manifestations were high (72.1%) in IBD patients. Clinically significant primary ocular inflammation occurred in 8.2% of patients. The most common complication was DES. There was a higher rate of DES in patients with IBD compared to the control group. Evaluation of the eye should be a routine component in patients with IBD.
