The internal biliary fistula between the gallbladder or bile duct and intestinal tract is a rare disease. Because symptoms and signs of biliary fistula are not specific, these patients are commonly investigated with computed tomography, endoscopic retrograde cholangiopancreatography (ERCP) and barium study. Among them, a cholecystogastric fistula is a very rare type of biliary fistula. We recently experienced a case of cholecystogastric fistula and transmigration of the gallstone to the stomach. A 53-year- old woman was transferred with the impression of gallbladder cancer. On evaluating the cause of right upper abdominal pain and nausea, we confirmed the cholecystogastric fistula with gastroscopy, upper GI series and ERCP. Cholecystectomy and the repair of the fistula was done. 담도 누공은 담도와 주위 장기와의 비정상적인 통로가 형성되는 것이다. 담도 누공은 대부분 담석에 의해 발생한다고 보고되고 있다. 담도 누공은 전구 증상 없이 나타날 수 있으며, 특이적인 증상이 없고 진단이 다소 어렵다. 담도 누공은 대부분 담낭-십이지장 누공의 형태로 발견되나 위와 담낭 사이에 발생하는 누공은 매우 드물게 보고되고 있다. 저자들은 개인 의원에서 담낭암으로 의심되어 전원된 환자에서 담낭-위 누공 및 이 누공을 통해 위내로 배출된 담석을 진단하였기에 문헌 고찰과 함께 보고하는 바이다.

Irritable bowel syndrome (IBS) is a common disorder of the intestines characterized by a combination of chronic or recurrent gastrointestinal symptoms. Symptoms that are commonly associated with IBS include passage of clear or white mucus with a bowel movement, sensation of incomplete evacuation after haying a bowel movement, and relief of abdominal pain or discomfort transiently after defecation and abdominal bloating. In treating IBS, it is important for physicians to remember that IBS represents a spectrum of symptoms, including pain or discomfort, altered bowel habit, as well as additional symptoms, such as bloating rectal urgency. or painful bowel movement. These symptoms tend to fluctuate over time in the patient who is suffering from IBS. This makes symptom-directed treatment, such as treatment for diarrhea or constipation, somewhat less than optimal. Given the high prevalence of IBS both in primary and specialty practice, it is clear that physicians need to be aware of and feel comfortable using these available drugs.

Hepatic portal venous gas(HPVG) is a rare disease presenting as acute abdomen. There were first described in children with necrotizing enterocolitis in 1955. HPVG is caused by mesenteric ischemia but may have various etiologies. Predisposing factors that develop mesenteric ischemia include gastric ulcer disease, bowel obstruction, diverticulitis and sepsis. The presence of the air in the portal and mesenteric vein on radiographics has been associated with a mortality rate of more than 75% in earlier studies. Abdominal computed tomography has proven useful for detecting portomesenteric venous gas and pneumatosis intestinalis. We report a case of the patient with hepatic portal venous gas with pneumatosis intestinalis, which showed rapid progress of the disease and eventually died within 24 hours of admission.

This study attempted to analyze the relationship between facial sensitivity and psychological response to the behavioral intention of premium coffee brand users. Currently, coffee is the most in demand worldwide, and the coffee industry is highly evaluated for its importance as it is classified as a field that creates high value-added. Recently, customers who seek various flavors of coffee and a comfortable and cozy atmosphere that can be felt at expensive coffee shops are changing to a concept that forms and develops a culture, not just a tea drinking space. This paper was studied because it was found that the establishment of reasonable prices corresponding to service and product quality was an important factor, and the question of whether the price was set to a fair level was important. The survey targets adult men and women in Busan and Gyeongsangnam-do, and 235 copies were used for empirical analysis from March 1, 2022 to March 30, 2022. Multiple regression uses SPSS 20.0 and the results are as follows. First, price fairness had a significant positive effect on the psychological response (+) and second, price fairness had a significant positive (+) effect on facial sensitivity. Third, psychological responses showed a significant positive (+) effect on face sensitivity, and fourth, face sensitivity was found to have a significant positive (+) effect on behavioral intention. The results of this study will provide useful data for understanding the relationship between price fairness and psychological responses to the facial sensitivity of premium coffee brands.
