Objective: This study was designed to assess the correlation between gastrointestinal symptoms, depression, and anxiety in patients with irritable bowel syndrome (IBS). Method: New patients who visited the ${\bigcirc}{\bigcirc}$ Oriental Hospital completed standardized questionnaires. These consisted of questionnaires for IBS based on Rome III criteria, the Gastrointestinal Symptom Rating Scale (GSRS), the Beck Depression Inventory (BDI), and the Beck Anxiety Inventory (BAI). Results: A total of 103 patients participated. Among them, IBS was observed in 42 patients. There was a weak correlation between GSRS and BDI, but it was not statistically significant. There was a statistically significant weak correlation between GSRS and BAI. The main symptom factors affecting BAI were borborygmus, increased flatus, sucking sensations in the epigastrium, and abdominal distension. Conclusion: There was a statistically significant correlation between gastrointestinal symptoms and anxiety in patients with irritable bowel syndrome.

Purpose: This study aimed to identify the effects of musculoskeletal symptoms and burden on presenteeism among nurses in a gastrointestinal endoscopy unit. Methods: This was an observational cross-sectional study. Data were collected through self-reported questionnaires administered to 140 nurses working in the gastrointestinal endoscopy unit of a hospital located in Busan metropolitan city. Results: The body part with the most musculoskeletal symptoms was the back (73.2%), and the most common musculoskeletal burden work was "when you have to stand or maintain the same posture for a long time in a lead apron protection clothes." The factors most related to work impairment were working hours, musculoskeletal symptoms, and musculoskeletal burden, with an explanatory power of 63.3%. Factors affecting perceived productivity were working hours and musculoskeletal symptoms, with an explanatory power of 29.2 %. Conclusion: To reduce work impairment and increase the perceived productivity of nurses in gastrointestinal endoscopy units, various programs and improved working environments are needed that can improve musculoskeletal symptoms and reduce musculoskeletal burden.

The purpose of this study was 2-fold: 1) to investigate the prevalence of gastrointestinal parasite infection in cats reared in Daegu, Republic of Korea and 2) to assess the efficacy and safety of a topical emodepside/praziquantel formulation for cats with parasitic infections. The gastrointestinal parasite infections were examined microscopically using the flotation method. Of 407 cats, 162 (39.8%) were infected by at least one gastrointestinal parasite, including Toxocara cati (63.0%), Toxascaris leonina (31.5%), Taenia taeniaeformis (3.7%), and Cystoisospora felis (1.9%). None of the infected animals had multiple infections. When the data were analyzed according to sex, age, and type of cat, stray cats showed statistically higher prevalence than companion cats (P<0.05). On the 5th day after treatment, no parasitic eggs were detected using microscopic examination. In addition, no adverse effects, such as abnormal behaviors and clinical symptoms, were observed in the cats treated with the drug. These results quantify the prevalence of gastrointestinal parasites in cats in Daegu, Republic of Korea, and show that topical emodepside/praziquantel is a safe and effective choice for treating the parasitic infections in cats.

Purpose: Textbook outcome is a comprehensive measure used to assess surgical quality and is increasingly being recognized as a valuable evaluation tool. Delta-shaped anastomosis (DA), an intracorporeal gastroduodenostomy, is a viable option for minimally invasive distal gastrectomy in patients with gastric cancer. This study aims to evaluate the surgical outcomes and calculate the textbook outcome of DA. Materials and Methods: In this retrospective study, the records of 4,902 patients who underwent minimally invasive distal gastrectomy for DA between 2009 and 2020 were reviewed. The data were categorized into three phases to analyze the trends over time. Surgical outcomes, including the operation time, length of post-operative hospital stay, and complication rates, were assessed, and the textbook outcome was calculated. Results: Among 4,505 patients, the textbook outcome is achieved in 3,736 (82.9%). Post-operative complications affect the textbook outcome the most significantly (91.9%). The highest textbook outcome is achieved in phase 2 (85.0%), which surpasses the rates of in phase 1 (81.7%) and phase 3 (82.3%). The post-operative complication rate within 30 d after surgery is 8.7%, and the rate of major complications exceeding the Clavien-Dindo classification grade 3 is 2.4%. Conclusions: Based on the outcomes of a large dataset, DA can be considered safe and feasible for gastric cancer.

Objectives : Prevalence of night eating habit associated with substance use and obesity is increasing rapidly in children and adolescents. Further, staying up late and eating snacks late at night were known as leading health risk behaviors for children, suggesting the potential adverse effect of night-eating habit on children. However, only few reports had been issued on the effect of night-eating habit on gastrointestinal symptom and SUI-TAI(水滯) symptom of children. Therefore, we aimed to investigate clinical characteristics of children by night-eating symptom status. Methods : Parents were asked to give a detailed answer to a systemized medical history questionnaire concerning night-eating habit, gastrointestinal symptom and SUI-TAI symptom of their children. Medical records of 28 children treated in the Department of Pediatrics, Hospital of Oriental Medicine, were the subject of this study. Clinical characteristics of two groups of children who with no night-eating habit and frequent night-eating group(eating at night more than 3 times per week) were analysed. In addition, the correlation analysis between clinical characteristics were performed. Results : Children with frequent night-eating habit(n=7, more than 3 days of night-eating a week) were observed to have more aggravated gastrointestinal symptom and SUI-TAI symptom compared with those without night-eating habit(n=13). In parallel, the association of gastrointestinal symptom and SUI-TAI symptom was demonstrated(n=28). Conclusions : It is notable that deranged gastrointestinal function and aggravated SUI-TAI symptom were observed among children generally regarded as healthy. Therefore, endeavors to correct night-eating habit as well as to treat aggravated gastrointestinal and SUI-TAI symptoms are needed for the promotion of health of children.

Massive gastric mucosal ruptures during upper gastrointestinal endoscopy in patients with esophageal hiatal hernias are rare. However, tearing of the gastric mucosa alone, without tearing of the gastroesophageal junction, is even rarer. This study reports a case of a large mucosal rupture that occurred on the posterior wall of the upper body of the stomach during upper gastrointestinal endoscopy in an 83-year-old woman with an esophageal hiatal hernia while sedated. The patient was treated with endoclips for the rupture.

ICR 마우스 위장관 8개 부위(위저부, 유문부, 십이지장, 공장, 회장, 맹장, 결장 및 직장)에서 위장관내분비 세포의 부위별 분포 및 상대적 빈도를 somatostain, serotonin, glucagon, chloecystokinin(CCK)-8, secretin, pancreatic polypeptide(PP) 및 gastrin 등 총 7종류의 항혈청을 이용한 면역조직화학적 방법으로 관찰하였던 결과 somatostain, serotonin, glucagon, CCK-8, secretin, 및 gastrin 면역반응세포의 7종류의 내분비세포가 관찰되었다. 본 실험의 결과 장관부위에서는 주로 타원형 또는 방추형의 개방형 세포(open-typed cell)들이 관찰된 반면 위저부와 유문부에서는 주로 원형의 폐쇄형 세포(close-typed cell)을이 관찰되었다. 이들 면역반응세포들의 부위별 분포는 위장관 각 부위에 따라 매우 다양하게 관찰되었다. Somatostain 면역반응세포들은 대장을 제외한 위장관에서 전 부위에서 관찰되었고, serotonin 면역반응세포들은 전 위장관에 걸쳐 관찰되었으며, ICR 마우스에서 가장 높은 빈도를 나타내었다. Glucagon 면역반응세포들은 위저부와 직장에 국한되어 관찰되었으며, 각각 중등도 및 소수의 빈도를 나타내었다. CCK-8 면역반응세포들은 유문부, 십이지장 및 회장에서 각각 다수, 중등도 및 극소수의 빈도로 관찰되었다. 한편 secretin 면역반응세포들은 각각 소수 및 극소수의 빈도로 십이지장과 회장에 국한되어 출현하였고, gastrin 면역반응세포들은 유문부에 국한되어 다수 관찰되었다. 그러나 PP 면역반응세포들은 전 위장관에 걸쳐 관찰되지 않았다. 결론적으로 ICR 마우스의 위장관내분비세포의 부위별 분포 및 상대적 빈도는 다른 포유동물과 유사하게 관찰되었으나, 일부 특이한 양상을 나타내기도 하였다.

The present study was undertaken to determine whether combined treatment with prokinetic trimebutine and mosapride has a synergic effect on gastrointestinal motility and visceral pain associated with gastrointestinal dysfunction. To develop effective gastroprokinetic agents with greater potencies than trimebutine or mosapride for the treatment of gastrointestinal tract disease, a mixture of trimebutine and mosapride was designed and prepared. In the present study, treatment with trimebutine alone showed a dose-dependent effect on propelling movements of normal small and large intestine in mice, whereas mosapride effected only small intestine motility. Co-administration of trimebutine with mosapride, a well-established prokinetic drug, produced a synergistic influence on normal small intestine motility, but demonstrated an unclear effect on large intestine motility, with a slight tendency to reduce the propelling time. In a stress model, the small and large intestine motilities were significantly decreased. The reduction of intestine motility was restored to a normal level and the restoring effect was more pronounced in the combined treatment with trimebutine plus mosapride than treatment with trimebutine or mosapride alone. Furthermore, treatment with trimebutine plus mosapride significantly decreased acute visceral pain which was not controlled by trimebutine or mosapride alone. These data suggest that combination therapy with trimebutine plus mosapride has a synergic effect on small and large intestine motility and visceral pain control in gastrointestinal disorders.
