Colonoscopy is commonly used to screen for and diagnose colorectal disease, and adequate bowel preparation is crucial to its quality. As bowel preparation regimens vary, it is important that clinicians understand each and select the proper one for each patient. Accordingly, here we investigated recent studies and describe how to choose the optimal bowel preparation regimen. We detail composition, dosages, efficacy, contraindications, and precautions of commonly used regimens including 4 L polyethylene glycol (PEG), 2 L PEG+ascorbic acid, 1 L PEG+ascorbic acid, trisulfate (oral sulfate solution/tablets), and sodium picosulfate/magnesium citrate. Here we describe that the most recently introduced 1 L PEG and oral sulfate tablets, which were developed to improve convenience and compliance, differ in composition and efficacy between South Korea and foreign countries. This review presents new evidence of and differences among products to increase clinician understanding.

Especially, because the number of patient who present atypical symptoms of acute appendicitis increases, it is hard to be diagnosed as acute appendicitis and it is often misdiagnosed as other disease.
We report one case of acute appendicitis diagnosed by colonoscopy performed to evaluate for atypical abdominal pain.

From January to August 2001, the colonoscopic finding and pathologic reports of 527 patients under 50 years old who underwent colonoscopy were reviewed retrospectively. The advanced polyp was defined as an adenoma more than 10mm in diameter or with the histology of villous or high grade dysplasia.
Total 94 colonic polyps(17.8%) were analyzed. On age distribution, 65 cases(69.1%) were in forth decade, 25 cases(26.6%) in third decade. Abdominal pain(29.8%) was the most common cause of taking the colonoscopic examination followed by rectal bleeding(18.1%), asymptomatic screening(12.7%). Rectosigmoid area was the most common site of polyps in 63.8%. On the pathologic review, adenoma was found 55.1%, inflammatory polyp 38.5% and hyperplastic polyp 6.4%. Advanced adenomas were 17.9%(17/156) and adenomas with focal carcinomatous changes were 1.9%(3/156). Patients who had symptoms of abdominal pain or rectal bleeding, multiple polyps or familial history of colorectal cancer had a higher prevalence of advanced adenoma than that of non-advanced adenoma(
This study showed that major symptoms of patients with advanced polyps under 50 years old were abdominal pain and rectal bleeding. The symptoms, multiplicity of polyp and family history were important indicator of advanced polyps. Further study was needed for reasonable indication and cost effectiveness for colonoscopic examination in young age people.
, Hee Sun Kim, Yoonjung Kim, Eun Kyung Byun, Young Sook Lee, Soo Jin Jung, Youn Ju Ryu The aim of this study was to investigate the characteristics of colonic mucosal lesions by colonoscopy and for assessment of clinical features in patients with acute diarrhea.
From March 2000 to August 2001, one hundred and ten patients with watery or bloody diarrhea lasting less than 14 days. The colonoscopic finding was assessed to extent of lesion(rectum, left, right and total colon) and severity of inflammation(mild ; erythema and edema, moderate ; exudates and blood coagula, severe ; hemorrhage and ulcer).
Male was 60(54.5%) and median age was 43 years(range ; 15-84 years). The day of colonoscopy from symptom onset was 5 days(range 1-14 days). The causative food was flesh and meat, sea food and fish, and vegetable in order. Eight patient have history of travel including oversea. Pancolitis was the most common finding(46/110, 41.8%) and the normal colonoscopic finding was noted in eighteen cases(16.4%). The mild inflammation was 40(43.5%), moderate was 26(28.3%) and severe was 26(28.3%). The severity of inflammation was significantly correlated to the extent of lesion(p<0.05, r=0,655).
The colonoscopy in acute infectious colitis was a useful to evaluate the extent of lesion and the severity of disease.
