Practices and perceptions of 5-aminosalicylic acid use in Crohn’s disease: a nationwide survey of physicians in Korea by KASID Guidelines Taskforce Team: June Hwa Bae, Seung Yong Shin, Dong Hyun Kim, Seung Min Hong, Eun Mi Song, Ji Eun Kim, Young Joo Yang, Jiyoung Yoon, Sang-Bum Kang, Eun Soo Kim, Sung Eun Kim, Seong-Jung Kim, Jun Lee, Soo-Young Na, Soo Jung Park, Sang Hyoung Park, Won Moon, Sung-Ae Jung, KASID Guidelines Taskforce Team of the Korean Association for the Study of the Intestinal Diseases (KASID); Intest Res 2025;23(4):491-501.

Abstract PDF Supplementary Material PubReader ePub: Background/Aims
Despite international guidelines recommending against the use of 5-aminosalicylic acid (5-ASA) for Crohn’s disease (CD), it remains widely prescribed. This study aimed to investigate current patterns of 5-ASA use and physicians’ perceptions of its efficacy among Korean specialists.
Methods
A nationwide online survey was conducted in August 2025 targeting Korean gastroenterologists and colorectal surgeons managing inflammatory bowel disease. The questionnaire included 19 items addressing prescribing behaviors, perceived efficacy, and clinical decision-making regarding 5-ASA in CD.
Results
A total of 118 out of 124 physicians (95.2%) responded to the survey. The majority (67.8%) reported prescribing 5-ASA to more than half of their patients with CD. Standard to high doses ( > 2 g/day) were commonly used (94.9%), and timedependent formulations were preferred (92.4%). Although 55.1% used 5-ASA irrespective of disease location, it was frequently prescribed for colonic/ileocolonic disease (57.7%). Physicians primarily used 5-ASA in cases of non-active or mildly active CD. Notably, over 70% of respondents perceived 5-ASA to have a marginal yet beneficial effect on clinical remission, biomarker improvement, and mucosal healing. Approximately one-third of physicians reported continuing 5-ASA even after initiating biologics or small molecules.
Conclusions
This survey reveals a substantial gap between clinical guidelines and current practice in Korea regarding 5-ASA use for CD. Many physicians continue to view 5-ASA as a relevant option, particularly for patients with low inflammatory burden. These discrepancies likely reflect practical factors such as clinical experience and drug characteristics, which should be carefully considered before excluding 5-ASA from CD management.

Comparative outcomes of acute colonic diverticulitis in immunocompromised versus immunocompetent patients: a systematic review and meta-analysis: Jae Gon Lee, Yong Eun Park, Ji Young Chang, Hyun Joo Song, Duk Hwan Kim, Young Joo Yang, Byung Chang Kim, Shin Hee Lee, Myung-Won You, Seong-Eun Kim; Intest Res 2023;21(4):481-492. Published online May 31, 2023; DOI: https://doi.org/10.5217/ir.2023.00005

Abstract PDF Supplementary Material PubReader ePub

Background/Aims
Immunocompromised patients with acute colonic diverticulitis are at high risk for complications and failure of non-surgical treatment. However, evidence on the comparative outcomes of immunocompromised and immunocompetent patients with diverticulitis is lacking. This systematic review and meta-analysis investigated the outcomes of medical treatment in immunocompromised and immunocompetent patients with diverticulitis.
Methods
A comprehensive literature search was conducted in PubMed, Embase, and the Cochrane Library. Studies comparing the clinical outcomes of immunocompromised and immunocompetent patients with diverticulitis were included.
Results
A total of 10 studies with 1,946,461 subjects were included in the quantitative synthesis. The risk of emergency surgery and postoperative mortality after emergency surgery was significantly higher in immunocompromised patients than in immunocompetent patients with diverticulitis (risk ratio [RR], 1.76; 95% confidence interval [CI], 1.31–2.38 and RR, 3.05; 95% CI, 1.70–5.45, respectively). Overall risk of complications associated with diverticulitis was non-significantly higher in immunocompromised than in immunocompetent patients (RR, 1.24; 95% CI, 0.95–1.63). Overall mortality irrespective of surgery was significantly higher in immunocompromised than in immunocompetent patients with diverticulitis (RR, 3.65; 95% CI, 1.73–7.69). By contrast, postoperative mortality after elective surgery was not significantly different between immunocompromised and immunocompetent patients with diverticulitis. In subgroup analysis, the risk of emergency surgery and recurrence was significantly higher in immunocompromised patients with complicated diverticulitis, whereas no significant difference was shown in mild disease.
Conclusions
Immunocompromised patients with diverticulitis should be given the best medical treatment with multidisciplinary approach because they had increased risks of surgery, postoperative morbidity, and mortality than immunocompetent patients.

Use of device-assisted enteroscopy in small bowel disease: an expert consensus statement by the Korean Association for the Study of Intestinal Diseases: Han Hee Lee, Jin Su Kim, Hyeon Jeong Goong, Shin Hee Lee, Eun Hye Oh, Jihye Park, Min Cheol Kim, Kwangwoo Nam, Young Joo Yang, Tae Jun Kim, Seung-Joo Nam, Hee Seok Moon, Jae Hyun Kim, Duk Hwan Kim, Seong-Eun Kim, Seong Ran Jeon, Seung-Jae Myung, The Small Intestine Research Group of the Korean Association for the Study of Intestinal Diseases (KASID); Intest Res 2023;21(1):3-19.

Abstract PDF PubReader ePub

The introduction of device-assisted enteroscopy (DAE) in the beginning of 21st century has revolutionized the diagnosis and treatment of diseases of the small intestine. In contrast to capsule endoscopy, the other main diagnostic modality of the small bowel diseases, DAE has the unique advantages of observing the region of interest in detail and enabling tissue acquisition and therapeutic intervention. As DAE becomes an essential procedure in daily clinical practice, there is an increasing need for correct guidelines on when and how to perform it and what technical factors should be considered. In response to these needs, the Korean Association for the Study of Intestinal Diseases developed an expert consensus statement on the performance of DAE by reviewing the current evidence. This expert consensus statement particularly focuses on the indications, choice of insertion route, therapeutic intervention, complications, and relevant technical points.

Abstract PDF PubReader ePub

Many unexpected problems have resulted from the unprecedented coronavirus disease 2019 (COVID-19) pandemic. The optimal management of patients with inflammatory bowel disease (IBD) during the COVID-19 pandemic has also been a challenge. Therefore, the Korean Association for the Study of Intestinal Diseases (KASID) developed a consensus statement of experts regarding the management of IBD during the COVID-19 pandemic. This consensus statement made recommendations regarding the risk and treatment of COVID-19 in IBD patients. This statement emphasizes that IBD is not a risk factor for COVID-19, and care should be taken not to exacerbate IBD in patients in remission state by maintaining their medications, except for corticosteroids.

Abstract PDF PubReader ePub

Coronavirus disease 2019 (COVID-19), caused by the novel coronavirus, is threatening global health worldwide with unprecedented contagiousness and severity. The best strategy to overcome COVID-19 is a vaccine. Various vaccines are currently being developed, and mass vaccination is in progress. Despite the very encouraging clinical trial results of these vaccines, there is insufficient information on the safety and efficacy of vaccines for inflammatory bowel disease (IBD) patients facing various issues. After reviewing current evidence and international guidelines, the Korean Association for the Study of Intestinal Diseases developed an expert consensus statement on COVID-19 vaccination issues for Korean IBD patients. This expert consensus statement emphasizes that severe acute respiratory syndrome coronavirus 2 vaccination be strongly recommended for IBD patients, and it is safe for IBD patients receiving immunomodulatory therapy.
