Background/Aims
Spontaneous intramural small bowel hematoma (SISBH) is an extremely rare complication of anticoagulant or antiplatelet therapy. We assessed the clinical characteristics and outcomes of patients with SISBH according to the anatomical location of the hematoma.
Methods
From January 2003 to February 2016, medical records for all patients hospitalized for SISBH at 2 tertiary referral hospitals were retrospectively reviewed. The primary outcome was requirement for surgery.
Results
A total of 37 patients were enrolled. The mean age was 74.1 years. Among them, 33 patients (89.2%) were taking anticoagulant and/or antiplatelet agents. Duodenal intramural hematoma was detected in 4 patients (10.8%), jejunal in 16 (43.2%), and ileal in 17 (45.9%). Compared to jejunal and ileal involvement, duodenal intramural hematoma was significantly associated with high Charlson comorbidity index and low levels of white blood cells, hemoglobin, and platelets in the blood. SISBH in the duodenum was related to thrombocytopenia in 3 patients following systemic chemotherapy for malignancy. All patients with SISBH showed clinical improvement with conservative therapy. Mean length of hospital stay was 9.35 days. Independent predictors of a hospital stay of more than 7 days were body weight less than 60 kg (odds ratio [OR], 12.213; 95% confidence interval [CI], 1.755–84.998; P=0.011) and a history of cerebrovascular accidents (OR, 6.667; 95% CI, 1.121–39.650; P=0.037).
Conclusions
Compared to jejunal and ileal involvement, thrombocytopenia may result in spontaneous duodenal intramural hematoma among patients who are treated with systemic chemotherapy for malignancies. Patients with SISBH have excellent clinical outcomes with conservative therapy regardless of the anatomical location of the hematoma.

Background/Aims

Patients with ulcerative colitis (UC) are at high risk for cytomegalovirus (CMV) reactivation. The usefulness of the CMV antigenemia assay in active UC patients has rarely been studied. We assessed whether the assay detects CMV colitis and predicts clinical outcomes in patients with UC.

Methods

We retrospectively reviewed the medical records of patients hospitalized for moderate-to-severe UC from 2003 to 2012. Positive CMV antigenemia was defined as ≥1 pp65-positive cell per 2×10⁵ polymorphonuclear neutrophils. CMV colitis was defined as the presence of inclusion bodies and/or positive immunohistochemistry in the colonic mucosa. The primary outcome was steroid refractoriness, defined as the absence of clinical improvement after intravenous high-dose steroid administration.

Results

A total of 43 patients were enrolled. CMV antigenemia was detected in 12 (27.9%) patients. Positive CMV antigenemia was significantly associated with CMV colitis (P =0.001). The sensitivity and specificity of positive CMV antigenemia for diagnosing CMV colitis were 66.7% and 87.1%, respectively. Steroid refractoriness was found in 11 of 12 (91.7%) and 12 of 31 (38.7%) patients with positive and negative CMV antigenemia, respectively (P =0.002). The independent predictors for steroid refractoriness were positive CMV antigenemia (adjusted odds ratio [OR], 7.73; 95% confidence interval [CI], 1.22-49.19; P =0.030) and a shorter duration from the diagnosis of UC (adjusted OR, 0.99; 95% CI, 0.98-0.99; P =0.025).

Conclusions

The CMV antigenemia assay shows low sensitivity but high specificity for detecting CMV colitis and may predict steroid-refractory UC. Early rescue therapy might be considered in UC patients positive for CMV antigenemia.

Background/Aims

Few studies have investigated the prognosis of non-gastric gastrointestinal stromal tumors (GISTs) under the modified National Institutes of Health (NIH) consensus criteria in Korea. This study aims to clarify the clinical usefulness of the modified NIH criteria for risk stratification.

Methods

From January 2000 through October 2012, 88 patients who underwent curative resection for primary GISTs were included in this study. The enrolled patients were stratified to predict recurrence by the original NIH criteria and modified NIH criteria.

Results

In all, 88 patients had non-gastric GISTs, including 82 and 6 patients with GISTs of the small intestine and colorectum, respectively. The mean age was 57.3±13.0 years, and the median follow-up duration was 3.40 years (range, 0.02-12.76 years). All patients who were placed in the intermediate-risk category according to the original NIH criteria were reclassified into the high-risk category according to the modified NIH criteria. Therefore, the proportion of cases in the intermediate-risk category declined to 0.0% from 25.0% (22/88), and the proportion of cases in the high-risk category increased to 43.2% (38/88) from 18.2% (16/88) under the modified NIH criteria. Among the 22 reclassified patients, 6 (27.3%) suffered a recurrence during the observational period, and the recurrence rate of high-risk category patients was 36.8% (14/38).

Conclusions

Patients in the high-risk category according to the modified NIH criteria had a high GIST recurrence rate. Therefore, the modified NIH criteria are clinically useful in selecting patients who need imatinib adjuvant chemotherapy after curative surgical resection.

A Case of Immune Thrombocytopenic Purpura Associated with Preexisting Ulcerative Colitis Treated with Colectomy and Splenectomy: Jee Hye Kwon, Changhyun Lee, Ji Min Choi, Yoo Min Han, Young Hoon Choi, June Young Lee, Hyuk Yoon, Jaeyoung Chun, Kyu Joo Park, Jong Pil Im, Sang Gyun Kim, Joo Sung Kim, Hyun Chae Jung; Intest Res 2013;11(4):310-316.

Abstract PDF

Ulcerative colitis is a chronic inflammatory bowel disease of unknown etiology, associated with extraintestinal manifestations, including the rarely reported immune thrombocytopenic purpura. Here, we present a case of immune thrombocytopenic purpura associated with preexisting ulcerative colitis. The patient was diagnosed with ulcerative colitis 13 years ago. Two years after diagnosis, he presented with hematochezia and active ulcerative colitis. Despite steroid use, the platelet count gradually decreased to 21,000/mm3. Hematochezia and the platelet count recovered after the administration of cyclosporine, and ulcerative colitis was in near complete remission for 11 years. However, the patient was re-admitted for hematochezia and thrombocytopenia persisting over a month. Medical management including increased doses of steroids in combination with cyclosporin failed to control hematochezia and thrombocytopenia. Immune thrombocytopenic purpura was suspected on the basis of normocellular marrow with a normal number of megakaryocytes. To treat uncontrolled colitis and steroid-refractory thrombocytopenia, total proctocolectomy with ileal pouch-anal anastomosis and splenectomy were performed. The patient was followed up for 10 months after surgery and was found to be in good health with a normal platelet count. Therefore, colectomy alone or in combination with splenectomy should be considered in cases of life-threatening ulcerative colitis complicated with steroid-refractory immune thrombocytopenic purpura.

Abstract PDF

Crohn's disease is a chronic inflammatory disease that can involve the entire gastrointestinal tract. Several studies indicate that Crohn's patients with long disease duration have an increased risk of small bowel or colorectal cancer. In Korea, only a few cases of Crohn's disease-related small bowel or colorectal cancer have been reported. Here, we described 3 cases of colorectal cancer and 2 cases of small bowel cancer in patients with Crohn's disease. Among 5 patients, 3 had Crohn's disease-related lower gastrointestinal malignancy and the other 2 had sporadic lower gastrointestinal malignancies. Since the diagnosis of Crohn's disease-related lower gastrointestinal malignancy tends to be delayed, the development of malignancy should be considered in patients with long duration of Crohn's disease if patients have refractory symptoms despite intensive medical treatment. Surgical consultation should not be delayed. (Intest Res 2013;11:127-133)

Jejunal Adenocarcinoma as Part of Metachronous Triple Primary Cancers of the Digestive Tract in Patient with Hereditary Nonpolyposis Colorectal Cancer: Mun Sun Choi, Hyun Chae Jung; Intest Res 2011;9(2):158-161. Published online August 30, 2011; DOI: https://doi.org/10.5217/ir.2011.9.2.158

Abstract PDF: Hereditary nonpolyposis colorectal cancer (HNPCC) is an autosomal dominant inherited disease characterized by onset at a relatively early age, an excess of synchronous and metachronous tumors, and a variety of extracolorectal malignancies. Small bowel carcinoma reported, is included in the tumor spectrum of HNPCC, but the frequency of occurrence of this tumor in HNPCC patients is comparatively rare. In Korea, several cases of multiple primary cancers in patients with HNPCC have been reported, however, primary jejunal adenocarcinoma in conjunction with multiple primary cancers in the digestive tract has rarely been reported. Recently, we evaluated a 61-year-old male diagnosed with metachronous triple primary cancers of the jejunum, stomach, and colon. We report this rare case of primary jejunal adenocarcinoma as a part of metachronous triple cancers along with a review of the relevant literature. (Intest Res 2011;9:158-161)

A Case of Chronic Colonic Pseudo-obstruction with Visceral Myopathy: Kyoung Sup Hong, Kyu Joo Park, Sung Hye Park, Sang Gyun Kim, Hyun Chae Jung, In Sung Song, Joo Sung Kim; Intest Res 2008;6(2):145-149. Published online December 30, 2008

Abstract PDF: Chronic colonic pseudo-obstruction is a rare disease that results in colorectal dilatation without any obstructing lesions. Colonic dilatation does not usually cause colonic wall thickening and colonic visceral myopathy with muscular hypertrophy has not been reported in Korea. A 31-year-old female patient was transferred for treatment of refractory constipation accompanied by megacolon. She had suffered from recurrent attacks of severe abdominal pain with the sensation of a mass in the left lower quadrant. An abdominal CT revealed a large luminal dilatation of the sigmoid colon where massive stool was impacted. There was no obstructing lesion or luminal dilatation of the rectum. To relieve her refractory symptoms, a total colectomy with an ileorectal anastomosis was performed. Pathologic examination of the sigmoid colon revealed that the muscle layers were dysplastic and hypertrophied, and the innervations into the muscle fibers were markedly decreased. She was discharged without any intra-abdominal symptoms. (Intest Res 2008;6:145-149)

Clinical Features and Therapeutic Responses of Abdominal Actinomycosis: Ji Won Kim, Ji Bong Jeong, Yong Jin Jung, Byung Kwan Kim, Kook Lae Lee, Su Jong Yu, Mi Na Kim, Joo Sung Kim, Hyun Chae Jung, In Sung Song; Intest Res 2007;5(2):177-183. Published online December 30, 2007

Abstract PDF: Background/Aims
Abdominal actinomycosis is a rare entity and difficult to differentiate from a malignant neoplasm. A study of clinical features and therapeutic responses will contribute to the understanding of this disease. Methods: We analyzed the clinical features and therapeutic responses of 12 cases of abdominal actinomycosis from 1989 to 2007. Results: The male to female ratio of patients was 1：1, and the patients had a median age of 50 years (range 38-60 years). Abdominal pain was the most common symptom, and seven of twelve patients had a history of abdominal surgery, trauma, DM or IUD (intrauterine device) use. An abdominal CT examination revealed infiltrative lesions with disruption of the tissue plane in eight cases, and colonoscopic findings showed luminal stenosis, nodular lesions and ulceration in four cases. Surgical resection was performed in eleven cases with a right hemicolectomy with or without a salpingo-ooporectomy, a left hemicolectomy or mass excision. Of the eleven patients who underwent surgical resection, seven patients received intravenous penicillin G (10-15×106 U) followed by administration of oral antibiotics for a median 8 months (range 4-12 months) according to the presence of symptoms and signs. Conclusions: With combined adequate surgical resection and high-dose antibiotic therapy, the therapeutic responses are favorable in most of the abdominal actinomycosis patients.

A Case of Cytomegalovirus Colitis Complicated by Perforation after Short-term Steroid Therapy in a Patient with Eosinophilia: Jong Pil Im, Yoon Kyung Jeon, Sang Gyun Kim, Joo Sung Kim, Hyun Chae Jung, In Sung Song; Intest Res 2007;5(1):81-86. Published online June 30, 2007

Abstract PDF: Cytomegalovirus (CMV) infection is a rare event that has been reported mainly in immunocompromised patients who have HIV infection or receive immunosuppressive medication. Although CMV infection is generally asymptomatic in healthy individuals, CMV colitis in immunocompetent host can be potentially severe disease with significant morbidity, especially in older patients. We report a case of CMV colitis complicated by colonic perforation after short term steroid therapy in a patient with eosinophilia who has no evidence of immunosuppression. A high index of suspicion is crucial for early diagnosis of CMV colitis especially in older patients, even though obvious evidence of immunodeficiency is lacking. Colonoscopic examination including multiple biopsies is mandatory for diagnosis of CMV colitis, and antiviral agents should be started once the diagnosis is confirmed. (Intest Res 2007;5:81-86)

The Effect of DA-6034, a Synthetic Derivative of Flavonoid, on NF-κB Activity Stimulated with Lipopolysaccharide and Tumor Necrosis actor-α in Human Colonic Epithelial Cell Line: Ji Won Kim, Yong-Jin Jung, Ji Bong Jeong, Byeong Gwan Kim, Kook Lae Lee, Joo Sung Kim, Hyun Chae Jung, In Sung Song; Intest Res 2005;3(1):38-47. Published online June 30, 2005

Abstract PDF: Background/Aims
The nuclear factor-κB (NF-κB) is associated with expression of proinflammatory cytokines such as tumor necrosis factor-α (TNF-α) and interleukin-8 (IL-8). DA-6034, a derivative of flavonoid, has shown a potent anti-inflammatory effect in IBD animal model. The aim of this study was to characterize the anti-inflammatory activity of DA-6034 in terms of regulation of NF-κB. Methods: HT-29 cells were stimulated with lipopolysaccharide (LPS) or TNF-α alone or pretreated with DA-6034. The influence of DA-6034 on NF-κB DNA binding activity and inhibitory protein κB (IκB) activity was determined using an electrophoretic mobility shift assay (EMSA) and Western blot analysis. The RT-PCR method was used to determine the degree of gene expression of TNF-α and IL-8. Production of TNF-α and IL-8 protein was measured by ELISA. Results: DA-6034 prevented NF-κB activation stimulated with LPS and TNF-α and inhibited LPS- and TNF-α-induced IκB degradation. LPS-induced TNF-α mRNA expression and TNF-α-induced IL-8 mRNA expression were significantly decreased by DA-6034 pretreatment as compared to the absence of DA-6034 pretreatment. Conclusions: These results suggest that the inhibitory effect of DA-6034 on the production of TNF-α in LPS-stimulated and IL-8 in TNF-α-stimulated HT-29 cells may involve transcription regulation by suppression of NF-κB activation by interfering with IκB degradation.

Abstract PDF: Background/Aims
Colonic epithelial cells are increasingly recognized as playing an important role in host defense against microorganisms in the intestinal lumen and in inflammatory responses. When human intestinal epithelial cells are stimulated with proinflammatory cytokines or infected with microbial pathogens, they up-regulate a program of proinflammatory genes whose products are chemoattractant neutrophils and monocytes. However, little is known about the regulated production of T-cell chemoattractants by the intestinal epithelium. Methods: We studied chemokine (IP-10, Mig, I-TAC) expression of the human colonic mucosa by using enzyme-linked immunosorbent assay. Results: Expression of T-cell chemokine (IP-10, Mig, I-TAC) was increased in the mucosa of patients with Crohn's disease and ulcerative colitis. The production level of T-cell chemokine (IP-10, Mig, I-TAC) was decreased in the mucosa of patients with Crohn's disease after remission. Conclusions: Our finding indicated that under inflammatory conditions, mucosal T-cell chemokine production increased and attracted inflammatory cells. This result suggests that, at least in an inflammatory process, T-cell chemokine (IP-10, Mig, I-TAC) play a role in the pathogenesis of inflammatory bowel disease. (Intestinal Research 2004;2:58-64)
