title: [The effect of various cleansing methods for total fiber optic colonoscopy].
abstract: It is a fact that there are recent increasing trends of incidence of the colorectal carcinoma among other colorectal diseases. In such trend, the early detection remain to be most important by the air contrast barium enema and total fiber optic colonoscopy There are several ways to prepare the colon for barium enema and fiber optic colonoscopy which include several agents. The mechanical cleansing have been used most frequently since Brown's method was adapted to be most perfect for colon cleansing. The ideal laxatives and enema solutions were limited to adequate dose, it's effectiveness, patient's diet and bowel habit, minimal side effect, low cost and simple to perform. In order to compare the effectiveness of various cleansing solutions, six experimental methods were formed as shown; 1. normal saline enema, 2. castor oil with normal saline enema, 3. castor oil with soapsuds enema, 4. magnesium citrate with normal saline, 5. magnesium citrate with soapsuds enema and 6. ingestion of Golyetly solution. The authors have compared and determined the degree of cleanliness by an experienced endoscopist The total number of patients was 247, age distribution was 43 +/- 15 years old, and sex distribution was 133 males and 114 females. The grade I and II represented no difficulties at performing the fiber optic colonoscopy+, but grade III and IV had some difficulties, even unable to perform the fiber optic colonoscopy. The effectiveness the cleansing agents, represented with grade I and II was 95.9% (47/49) in method 6, 93.2% (54/58) in method 2, 83.3% (30/33) in method 3, 70.0% (28/40) in method 5, 66.7% (16/24) in method 1, and 45.7% (18/40) in method 4. Method 2 and 6 were the most effective in normal bowel habit patients. In constipated patients, method 6 was the most effective and all method except method 4 were effective in diarrhea patients. The degrees of less mucosal irritation by various bowel cleansing method were in the order of method 6(100%), 1(100%), 5(74%), 2(69%). In subjective symptoms and cleansing groups, abdominal distension, pain, nausea and vomiting were complained, and that's subject symptoms were in the order of method 3(88.9%), 6(79.6%), 1(75%), 5(72.5%), 2(72.4%), 4(67.5%). In conclusion, we believe that the Golytely of the mechanical cleansing solution for fiber optic colonoscopy was the most effective, but others depended on the patient's condition and bowel habit.
