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.

AbstractAbstract PDFPubReaderePub
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.

AbstractAbstract PDFPubReaderePub
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.

<b>Background/Aims</b><br/>

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.

Current status and future perspectives of capsule endoscopy
Hyun Joo Song, Ki-Nam Shim
Intest Res 2016;14(1):21-29.   Published online January 26, 2016

AbstractAbstract PDFPubReaderePub

Small bowel capsule endoscopy (CE) was first introduced 15 years ago, and a large amount of literature has since been produced, focused on its indication, diagnostic yields, and safety. Guidelines that have made CE the primary diagnostic tool for small bowel disease have been created. Since its initial use in the small bowel, CE has been used for the esophagus, stomach, and colon. The primary indications for small bowel CE are obscure gastrointestinal bleeding, unexplained iron deficiency anemia, suspected Crohn's disease, small bowel tumors, nonsteroidal anti-inflammatory drug enteropathy, portal hypertensive enteropathy, celiac disease, etc. Colon CE provides an alternative to conventional colonoscopy, with possible use in colorectal cancer screening. Guidelines for optimal bowel preparation of CE have been suggested. The main challenges in CE are the development of new devices with the ability to provide therapy, air inflation for better visualization of the small bowel, biopsy sampling systems attached to the capsule, and the possibility of guiding and moving the capsule by an external motion controller. We review the current status and future directions of CE, and address all aspects of clinical practice, including the role of CE and long-term clinical outcomes.

AbstractAbstract PDFPubReaderePub
<b>Background/Aims</b><br/>

Several recent studies have reported that the early use of infliximab (IFX) improves the prognosis of Crohn's disease (CD). However, no data are available from Asian populations, as the forementioned studies have all been conducted in Western countries. The aim of the current study was to evaluate the impact of early use of IFX on the prognosis of Korean patients with CD.

Methods

Patients with a diagnosis of CD established between July 1987 and January 2012 were investigated in 12 university hospitals in Korea. Because insurance coverage for IFX treatment began in August 2005, patients were assigned to either of 2 groups based on diagnosis date. The first group included patients diagnosed from July 1987 to December 2005, and the second from January 2006 to January 2012. We compared the cumulative probabilities of operation and reoperation between the two groups using the Kaplan-Meier method and a log-rank test.

Results

Of the 721 patients investigated, 443 (61.4%) comprized the second group. Although the cumulative probabilities of immunosuppressant (P<0.001) and IFX use (P<0.001) after diagnosis were significantly higher in the second group, there were no significant differences in cumulative probabilities of operation (P=0.905) or reoperation (P=0.418) between two groups.

Conclusions

The early use of IFX did not reduce CD-related surgery requirements in Korean patients with CD. These study results suggest that the early use of IFX may have little impact on the clinical outcome of CD in Korean patients in the setting of a conventional step-up algorithm.

Case Report
Superior Mesenteric Vein Thrombosis as an Early Presentation of Myelodysplastic Syndrome: A Case Report
Min Jung Kim, Hyun Joo Song, Woo Kun Kim, Sun Hyung Kim
Intest Res 2014;12(2):157-161.   Published online April 29, 2014
DOI: https://doi.org/10.5217/ir.2014.12.2.157
AbstractAbstract PDFPubReader

Mesenteric venous thrombosis (MVT) is a serious condition due to its potential association with mesenteric ischemia and infarction of the small bowel. Symptoms of MVT are often vague, making accurate diagnosis and sufficient treatment difficult. However, increased awareness and new imaging modalities for this condition have improved outcomes for patients with MVT. Treatment includes anticoagulation, transcatheter therapy, and surgery. In the present report, we describe the case study of a 62-year-old woman with a presenting diagnosis of superior MVT, who was finally diagnosed with myelodysplastic syndrome. The superior MVT spontaneously dissolved after the patient underwent 6 months of systemic anticoagulation therapy. Invasive surgery or bowel resection was not required.

AbstractAbstract PDF
Background/Aims
Colorectal cancer is the third most common cancer and the fourth leading cause of cancer death in Korea. Colonoscopic screening with removal of adenomas is an effective strategy for reducing the incidence and mortality of colorectal cancer. This study was conducted to investigate predictable factors of early colorectal cancer (ECC) in patients with advanced adenoma (AA), tumor in situ (Tis), and submucosal (SM) cancer diagnosed after colonoscopic polypectomy. Methods: etween August 2003 and June 2012, a total of 1,001 patients who underwent colonoscopic polypectomy in Jeju National University Hospital were enrolled in this study. Results: Patients were classified into four groups; non-AA, AA, Tis, and SM cancer. Compared to the AA group, the ECC group (n=50) had large adenoma size (12.2±5.9 mm vs. 15.3±6.5 mm, P<0.01), distal location (39.3% vs. 52.0%, P=0.05) and diabetes mellitus (13.1% vs. 25.0%, P=0.04). However, age, sex, body mass index, the mean number of polyps, and morphological features (polypoid vs. nonpolypoid lesions) were not significantly different between the AA and ECC groups. In multivariate analysis, adenoma size >15 mm (odds ratio [OR], 4.49; 95% confidence interval [CI] 2.40-8.38), distal location (OR, 2.59; 95% CI, 1.33-5.05), and diabetes mellitus (OR, 2.10; 95% CI, 1.07-4.43) were significantly associated with ECC. Of the 12 patients with SM cancer, 5 underwent additional operations and had no remnant carcinoma. Conclusions: Predictable factors of ECC after colonoscopic polypectomy may be adenoma size >15 mm, distal location and diabetes mellitus. (Intest Res 2013;11:169-177)

AbstractAbstract PDF
Peutz-Jeghers syndrome (PJS), is a rare autosomal dominant hereditary disorder. Intestinal hamartomatous polyps in association with melanocytic pigmentation of the skin and mucous membranes characterize PJS. Patients with PJS often have complications associated with the polyps, such as intestinal obstruction, intussusception, acute or chronic gastrointestinal bleeding, and the development of various types of cancer. Enteroclysis, small bowel follow-through, and push enteroscopy are generally used to identify the presence and location of small bowel polyps. Wireless capsule endoscopy (CE) has been confirmed as a feasible, safe, and sensitive test for the surveillance of small bowel polyps in patients with PJS and could replace radiographic small bowel surveillance. Here, a case of PJS newly diagnosed by CE is reported. The patient, a 30-year-old man who had developed rectal polyps associated with anal extrusion 7 years previously, had six episodes of hematochezia. (Intest Res 2010;8:181-186)

AbstractAbstract PDF
Although the gastrointestinal tract is one of the major sites of primary extranodal malignant lymphoma, the colon and small bowel are less frequently involved than the stomach. Mantle cell lymphoma comprising only 6% of the malignant non-Hodgkin lymphomas. Mantle cell lymphoma usually distributes from the esophagus to rectum, with advanced stages of peripheral lymphadenopathy, splenomegaly, and bone marrow infiltration. We report a case of ileocolic intussusception due to ileal mantle cell lymphoma. (Intestinal Research 2006;4:61-63)

AbstractAbstract PDF
Colonoscopy has become the principal method for diagnosis, treatment, and follow-up of colorectal disease. However, colonoscopy is an invasive procedure with an associated risk of complications. Especially, perforation of the colon and rectum during colonoscopy is a rare but serious complication. The choice of conservative versus surgical treatment for this complication remains controversial. In general, conservative treatment is reserved for patient in good general health with good bowel preparation and absence of signs of peritonitis during 24 to 48 hours following the perforation. Conservative management consists of intestinal rest, intravenous fluids and antibiotics, nasogastric tube decompression, and frequent clinical examination. In case of iatrogenic perforation, if the wound is immediately closed with clips, contamination of the peritoneal cavity can be minimized. We report here a patient who sustained iatrogenic rectal perforation caused by diagnostic colonoscopy that was successfully treated by endoscopic clipping therapy.

AbstractAbstract PDF
Background/Aims
The current practice of colonoscopic polypectomy reduce the risk of colorectal cancer. However, clinicopathologic charateristics of colorectal adenoma in population under 50 years old are uncertain. This study was performed to investigate clinicopathologic characteristics of colorectal adenoma and to determine colonoscopic indication of advanced adenoma in this population. Methods: A large scale, multicenter, prospective study was conducted from July 2003 through June 2004. Of the total 19,288 patients performed colonoscopy at 11 tertiary medical centers, we analysed 3,366 patients who undergone polypectomy and divided two groups by age of 50. Results: Among colonoscopic polypectomy, 10.7 percent (831/7,789) was younger patients and 22.0 percent (2.535/11,499) was older patients (p<0.001), and the detection rate of advanced adenoma was significantly lower in younger patients than older patients (17.7% vs. 21.1%, p<0.0050). In younger patients, the indications of colonoscopy were asymptomatic screening (32.7%), bowel habit change (24.0%), abdominal pain (16.8%), hematochezia (9.2%) and so on. The risk factors for advanced adenoma as colonoscopic indications in younger patients were hematochezia (OR 1.9, 95% CI 1.1-3.3) and referred patients from primary clinic (OR 2.0, 95% CI 1.3-3.0). Conclusions: This study documents lower prevalence of adenoma requiring polypectomy in younger patients compared with older patients and the low detection rate of advanced adenoma. Also, in this younger population, the colonoscopic polypectomy should be the first consideration in polyps with hamatochezia patients or referred patients from primary clinic.
