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

We aimed to assess the rate of histologic discrepancy (HD) between endoscopic forceps biopsy (EFB) and totally resected specimens in colorectal polyp and analyze the risk factors of discordant group, especially under-diagnosis (UD) cases before complete removal of colorectal polyp.

Methods

From 2010 to 2015, a total of 290 polyps in 210 patients which had baseline pathology report before endoscopic resection (ER) were analyzed. UD cases were defined as those in which the diagnosis changed to a more advanced histologic feature after ER.

Results

A change in the final histology after ER was noted in 137 cases (47.2%), and after excluding 9 insignificant cases, 128 cases were further categorized into over-diagnosed and under-diagnosed group. UD occurred in 86 cases (29.7%) and change from benign to malignancy was noted in 26 cases (8.9%). On univariate analysis, a larger polyp size (>10 mm) was significantly associated with both HD (P<0.001) and UD (P<0.001). Regarding polyp morphology, protruding or flat was not significantly important. On multivariate analysis, polyp size >10 mm was the single most significant predictor of both HD (P<0.001) and UD (P<0.001).

Conclusions

The HD and UD rates were 47.2% and 29.7%, respectively. Polyp size >10 mm was the most important predictor of both HD and UD. We should be careful in making treatment strategy of colorectal polyp based on histologic report of EFB especially when the size of polyp is >10 mm.

Endoscopy
Prospective analysis of factors associated with inadequate bowel preparation for colonoscopy in actual clinical practice
Dae Hyung Woo, Kyeong Ok Kim, Da Eun Jeong, Yoon Jeong Nam, Si Hyung Lee, Byung Ik Jang, Tae Nyeun Kim
Intest Res 2018;16(2):293-298.   Published online April 30, 2018

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

Inadequate bowel preparation can result in prolonged procedure time and increased missed lesion and complication rates. This prospective study aimed to evaluate bowel preparation quality and identify the predictive factors for inadequate bowel preparation in actual clinical practice.

Methods

We included 399 patients who underwent colonoscopy between June 2015 and July 2016. Using the Aronchick bowel preparation scale, we defined a score ≤2 as adequate preparation and a score >2 as inadequate preparation.

Results

Mean patient age was 58.38±12.97 years; 60.6% were male. Indications for colonoscopy included screening (69.7%) and surveillance after polyp removal (21.3%). A split-dose regimen was prescribed to 55.4% of patients. The inadequate bowel preparation rate was 28.1%. Overall, the median time between the last bowel preparation agent dose and start of colonoscopy was 5.0 hours (range, 1.5–16.0 hours); that of the adequate group was 5.0 hours (range, 1.5–16.0 hours); and that of the inadequate group was 5 hours (range, 2–23 hours). The mean bowel preparation scale score of the ascending colon (1.94±0.25) was significantly higher than that of other colon segments. On multivariate analysis, elderly age, history of cerebrovascular disease, history of gastrectomy or appendectomy, and total preparation solution uptake <2 L were the independent predictors of inadequate bowel preparation.

Conclusions

The inadequate bowel preparation rate was 28.1%. Risk factors included elderly age and history of cerebrovascular disease or abdominal surgery. Patients with these risk factors require special care and education.

Kyeong Ok Kim, Byung Ik Jang, Tae Nyeun Kim, Hee Jung Moon
Intest Res 2008;6(2):116-120.   Published online December 30, 2008
AbstractAbstract PDF
Background/Aims
The prevalence of colonic diverticulosis in Korea is lower than in Western contries and the involved site is different. But, the recently increasing prevalence in Korea may be due to changing life style and advances in diagnostic approachs. We analyzed the annual incidence and clinical manifestations of colonic diverticulosis of the patients who underwent colonofibroscopy. Methods: Medical records of 25,808 patients who underwent colonofibroscopy at Yeungnam University Medical Center from January 2000 to December 2007 were retrospectively reviewed. Results: Overall prevalence was 5.5%. The mean age of the patients was 57.02±12.41 years (range 19-97 years) and the most frequent occurrence (28.8%) occurred in the 7th decade of life. Male to female ratio was 977:159. The annual incidence rate increased from 4.6% to 7.2% since 2000. Diverticulum occurred more frequently in the right side colon (997 cases) than the left side colon (159 cases), with involvement of both sides in 62 cases. The rate of left sided colon increased with age. In 516 patients, only one diverticulum was detected and the other 682 patients had multiple diverticuli. Complications were evident in 51 cases, consisting of diverticulititis in 35 cases and bleeding in 16 cases. Conclusions: According to this single center analysis, the annual incidence rate of colonic diverticulosis is increasing with right sided colon as the predominant site. But, the frequency in left-sided colon is increasing with age. (Intest Res 2008;6:116-120)

The Effect of 5-Aminosalicylic Acid on Renal Function in Patients with Inflammatory Bowel Disease
Kyeong Ok Kim, Byung Ik Jang, Tae Nyeun Kim, Si Hyung Lee
Intest Res 2008;6(1):45-49.   Published online June 30, 2008
AbstractAbstract PDF
Background/Aims
An increasing number of case reports indicate the potential nephrotoxicity of 5-aminosalicylic acid (ASA). The aim of this study was to investigate the effect of long-term use of 5-ASA on renal function in patients with inflammatory bowel disease (IBD). Methods: The medical records of 318 patients with IBD that were treated with 5-ASA from 2001 to 2007 at Yeungnam University Hospital were reviewed. Changes in creatinine clearance (CCr), as measured by modification of diet with the renal disease study (MDRD) method, and risk factors were analyzed. Results: One-hundred patients were available for analysis. The male to female ratio was 55:45 and the mean age was 35.89±14.1 years. Fifty-eight patients were diagnosed with Crohn's disease and the other patients were diagnosed with ulcerative colitis. The mean treatment duration with 5-ASA was 2.6±2.5 years and 85 patients were treated with mesalazine and eight patients were treated with sulfasalazine. The mean baseline glomerular filtration rate (GFR) was 112.9±25.3 mL/min. The mean CCr declined to 106.3±28.3 ml/min/m2 with an annual decline of 1.44 ml/min/year/m2, but there was no statistically significant change in the mean CCr. Changes in the CCr were correlated with the pretreatment CCr. Conclusions: There was no statistically significant change in serum CCr. Although 5-ASA therapy in IBD patients resulted in no meaningful effect on renal function, the annual decline was within the normal range (0.4-1 mL/min/m2). Serial follow-up of GFR has significance. A large prospective study with a longer time is needed to confirm these findings. (Intest Res 2008;6:45-49)

Role of Echocardiography for the Evaluation of Ischemic Colitis
Kyu Hyung Lee, Byung Ik Jang, Kyeong Ok Kim, Si Hyung Lee, Jae Won Choi, Youn Sun Park, Sang Hoon Lee, Jun Young Lee, Jong Ryul Eun, Tae Nyeun Kim
Intest Res 2007;5(2):165-169.   Published online December 30, 2007
AbstractAbstract PDF
Background/Aims
Ischemic colitis is recognized as the most common intestinal vascular disorder, especially in the elderly. Several predisposing factors, especially a cardiac embolism, have been reported for ischemic colitis. The aims of this study were to evaluate the prevalence of cardiovascular disease and the role of echocardiography in ischemic colitis. Methods: Thirty-six patients with ischemic colitis from January 2000 to February 2007 were analyzed retrospectively. Results: The mean age of subjects was 68.8±8.4 years. The prevalence of cardiovascular disease in ischemic colitis patients was 33% (12/36 cases). There were eight ischemic heart disease cases, four valvular heart disease cases, three arrhythmia cases and one hypertrophic cardiomyopathy case. Echocardiography was performed in 21 cases; cardiovascular disease could be detected in 11/12 cases (92%) and four cases were previously unknown. Anticoagulant therapy was required in 25% of the patients. Factors influencing hospital stay were the presence of cardiovascular disease. The presence of an associated medical illness did not influence hospital stay. Conclusions: Echocardiography may be useful to evaluate predisposing factors and to determine the use of anticoagulation therapy in ischemic colitis. (Intest Res 2007;5:165-169)

Youn Sun Park, Byung Ik Jang, Tae Nyeun Kim, Jong Ryul Eun, Jae Won Choi, Kyu Hyung Lee, Kyeong Ok Kim, Si Hyung Lee, Mi Jin Kim
Intest Res 2007;5(1):77-80.   Published online June 30, 2007
AbstractAbstract PDF
Collagenous colitis is a clinicopathological syndrome characterized by: (1) chronic watery diarrhea and crampy abdominal pain and (2) thickened subepithelial collagen band and increased intraepithelial lymphocytes on histology. The mucosa generally appears endoscopically normal, although some nonspecific abnormalities such as patchy erythema, an abnormal vascular pattern or erythema may be found in upto one third of cases. Collagenous colitis is generally regarded as a benign disease and serious complication are uncommon. The frequency of colonic perforation in collagenous coliltis is unknown, but is probably very rare. Only 16 patients, excluding our cases, have so far been reported. We report a case of a 80-year-old woman with collagenous colitis who presented with colonic perforation two days after the colonoscopy. (Intest Res 2007;5:77-80)

Jae Won Choi, Byung Ik Jang, Youn Sun Park, Kook Hyun Kim, Jong Ryul Eun, Tae Nyeun Kim, Yong-Jin Kim, Chang Heon Yang
Intest Res 2006;4(2):106-109.   Published online December 30, 2006
AbstractAbstract PDF
A 51-year-old male visited our hospital for investigation of abdominal pain. Barium enema revealed luminal protruding mass at descending colon, but relatively intact colonic mucosal surface and several orifices with whitish exudates observed during colonoscopic examination, these findings suggested colonic diverticular disease with abscess. Also, specimen from ultrasound guided needle biopsy demonstrated chronic inflammation. Antibiotics applied, but mass lesion showed no improvement. The patient underwent operation two month later, the histologic exam demonstrated mucinous carcinoma. (Intestinal Research 2006;4:106-109)

AbstractAbstract PDF
Malignant mixed mullerian tumor (MMMT) is rare tumor of the ovary, representing less than 1% of all ovarian malignancies. MMMT is an uncommon tumor containing epithelial and mesenchymal components. Most of all were heterologous type and 80% occur in postmenopausal women. It is a aggressive and rapidly progressive tumor. MMMT is highly malignant and the prognosis is poor because of frequent metastasis and recurrance. The survival rate is very low in spite of surgery, chemotherapy and radiotherapy. The optimal treatment is still controversial. We experienced one recur case of malignant mixed mullerian tumor of the ovary in intestine and report with brief review of literature.

Positron Emission Tomography Finding of Small Bowel Crohn's Disease: Report of a Case
Youn Sun Park, Kook Hyun Kim, Jae Won Choi, Jong Ryul Eun, Byung Ik Jang, Tae Nyeun Kim
Intest Res 2006;4(1):57-60.   Published online June 30, 2006
AbstractAbstract PDF
Endoscopic and radiologic studies are frequently required in inflammatory bowel disease to determine disease activity, extent of disease, and delineating type. Positron emission tomography (PET) using fluorine-18-fluoro-deoxyglucose to identify metabolically active tissues may offer a simple noninvasive alternative to conventional studies in identification and localization of active intestinal inflammation with inflammatory bowel disease. Crohn's disease can also be detected by PET-CT. In this case, we discribe a small bowel Crohn's disease with PET-CT finding. There was intensely increased fluorine-18-fluoro-deoxyglucose uptake in terminal ileum area. (Intestinal Research 2006;4:57-60)
