A study on 97 patients with polyps diagnosed by endoscopy in central army hospital during 2000-2002 has shown that male/female (69/28), average ages (50), patients with one polyp, 2 polyps, 3 polyps, 4 polyps, 7 polyps and 8 polyps were 78, 15, 1, 1,1 and (1) respectively. The symptoms comprised abdominal pain (56%), dyspepsia (50%) blood and mucosa in feces (13%). Polyps concentrated in peripheral colon (43.80%). The rate of patients diagnosed early accounted for 4.2%
Colonic Polyps ; diagnosis

Acolonic polyp is a circumscribed mass of tissue that projects above the surface of the intestinal mucosa, which may be classified as either pedunculated or sessile, depending on whether or not it contains a discrete stalk, and according to the size and type. It has been believed that colorectal cancer evolves from a precursor lesion, the adenomatous polyp. The introduction of colonoscopy in the early 1970s, followed by the demonstration of the feasibility of colonoscopic polypectomy, provided the technology for the application of this concept to clinical practice. Colorectal cancer can be prevented through examination of the entire colon and identification of a polyp to be resected. According to the National Polyp Study in the USA, the incidence of colorectal cancer is reduced by 76~90% following colonoscopic polypectomy. Colonoscopy and polypectomy, when performed by adequately trained physicians, is a safe and effective procedure that can decrease deaths resulting from colorectal cancer.

BACKGROUND/AIMS: Detection of asymptomatic benign colon polyp is increasing because colonoscopy is widely used as a screening and diagnostic method. Fecal occult blood test is usually performed for the selection of patients requiring colonoscopy as well as mass screening for colon cancer. The aim of this study was to investigate the usefulness of fecal occult blood test performed prior to colonoscopy as a screening method of benign colon polyps. METHODS: Clinical characteristics of patients with polyps were evaluated according to the fecal occult blood test results in patients who underwent one-day fecal occult blood test and colonoscopic polypectomies from May 2003 to October 2004, retrospectively. RESULTS: A total of 942 colonoscopic polypectomies in 288 patients were evaluated. Fecal occult blood tests were positive only in 32 patients (11.1%). In univariate analysis, there was a significant difference in polyp size (p=0.02) and location (p=0.03) according to the presence of positive fecal occult blood tests. In addition, age of the patient (p=0.046), polyp size (mean, p=0.04; largest, p<0.01) and the number of polyps (p=0.045) were significantly different. However, in multivariate analysis, only polyp size larger than 20 mm was significantly related with positive fecal occult blood test with estimated odds ratio of 4.71. CONCLUSIONS: Fecal occult blood test has limitations as a screening test in asymptomatic patients with colon polyps, except for colon polyps larger than 20 mm in size.

BACKGROUND/AIMS: The efficacy and safety of endoscopic resection of colorectal cancer derived from sessile serrated adenomas or traditional serrated adenomas are still unknown. The aims of this study were to verify the characteristics and outcomes of endoscopically resected early colorectal cancers developed from serrated polyps. METHODS: Among patients who received endoscopic resection of early colorectal cancers from 2008 to 2011, cancers with documented pre-existing lesions were included. They were classified as adenoma, sessile serrated adenoma, or traditional serrated adenoma according to the baseline lesions. Clinical characteristics, pathologic diagnosis, and outcomes were reviewed. RESULTS: Overall, 208 colorectal cancers detected from 198 patients were included: 198 with adenoma, five with sessile serrated adenoma, and five with traditional serrated adenoma. The sessile serrated adenoma group had a higher prevalence of high-grade dysplasia (40.0% vs. 25.8%, P<0.001) than the adenoma group. During follow-up, local recurrence did not occur after endoscopic resection of early colorectal cancers developed from serrated polyps. In contrast, two cases of metachronous recurrence were detected within a short follow-up period. CONCLUSIONS: Cautious observation and early endoscopic resection are recommended when colorectal cancer from serrated polyp is suspected. Colorectal cancers from serrated polyp can be treated successfully with endoscopy.

Familial Adenomatous Polyposis (FAP) is a rare and autosomal dominantly inherited disorder characterized by the development of hundreds to thousands of colorectal polyps. Korean Polyposis Registry was established in July, 1990 for early detection and management of the FAP patient. Recently, we have experienced in our institution a case of the FAP family kindred living in Jeju Island of Korea. Their relatives have been managed for the past 20 years and are listed in the Korean polyposis registry. Pathologic diagnosis of our proband was stage III (T3N1M0) rectal cancer with thousands of colonic polyps. Intrafamilial strife and psychologic distress was significant due to the late detection and progression to rectal cancer. Therefore, we reviewed our case of the FAP family with literature regarding the psychologic distress and the role of the regional registry.

In the last few years, interest in the optical diagnosis of colorectal polyps has increased among gastroenterologists. Several studies have shown that the optical diagnosis of small colorectal polyps is safe and feasible in routine clinical practice and is comparable to histopathology. The Narrow-band Imaging International Colorectal Endoscopic Classification provides a validated criterion for the classification of neoplastic and nonneoplastic polyps as well as polyps with deep submucosal invasion using narrow band imaging during real-time colonoscopy. The aim of the present review is to assess the current evidence for and limitations of optical diagnosis and to propose a systematic approach for transferring research findings to patient care.

Narrow-band imaging (NBI) is a new imaging technology that was developed in 2006 and has since spread worldwide. Because of its convenience, NBI has been replacing the role of chromoendoscopy. Here we review the efficacy of NBI with/without magnification for detection, characterization, and management of colorectal polyps, and future perspectives for the technology, including education. Recent studies have shown that the next-generation NBI system can detect significantly more colonic polyps than white light imaging, suggesting that NBI may become the modality of choice from the beginning of screening. The capillary pattern revealed by NBI, and the NBI International Colorectal Endoscopic classification are helpful for prediction of histology and for estimating the depth of invasion of colorectal cancer. However, NBI with magnifying colonoscopy is not superior to magnifying chromoendoscopy for estimation of invasion depth. Currently, therefore, chromoendoscopy should also be performed additionally if deep submucosal invasive cancer is suspected. If endoscopists become able to accurately estimate colorectal polyp pathology using NBI, this will allow adenomatous polyps to be resected and discarded; thus, reducing both the risk of polypectomy and costs. In order to achieve this goal, a suitable system for education and training in in vivo diagnostics will be necessary.
