Colonoscopy in infancy and childhood with special regard to patient preparation and examination technique.

Plucnar BJ.

Only long colonoscopes, Olympus CF-LB2 or TCF-2L, were used for the 76 pediatric colonoscopies. A combination of a thin-liquid diet and laxatives was employed for 1-2 days before all the examinations. Physiological saline enemas on the eve and the morning of the day of examination were employed as supplementary colon-cleansing measures only in larger children. A mixture consisting of chlorpromazine, promethazine and pethidine chloride supplemented with atropine sulfate was used for premedication. Diazepam and ketamine chloride given i.v., or inhalation of halothane +N2O+O2 were employed for general anesthesia. Diazepam and phentanyl citrate given intravenously were used for the sedation of older children. The "classical" and Gaisford's modification of the procedure were found to be the most suitable examination techniques in infants and children. The coecum was reached in 75% of all examinations, and we had no complications with pediatric colonoscopy.

Electromanometry of the rectosigmoid in colonic diverticulosis.

In order to better understand the rectosigmoid motor activity in diverticular disease of the colon, we studied 186 patients, grouped according to their intestinal habit, the presence of diverticular disease and previous crisis of sigmoid diverticulitis. The intestinal habit was classified as: normal habit, irritable colon syndrome, diarrhea and constipation. The group of diverticulosis was classified by their intestinal habit and by diverticula localization (localized or generalized). The presence of systemic diseases or drug ingestion that could modify intestinal motility, were considered criteria for exclusion. The manometric study was preceded by food stimulus, with 650 kcal meal, by mechanic intestinal cleansing, with 500 ml of saline solution enema and by one hour resting period. A manometric catheter, was introduced by rectosigmoidoscopy, with open ended orifices situated at the sigmoid and upper rectum, respectively. The catheter was perfused by a capillary infusion system and the bowel pressures were registered for 30 minutes, in a thermal paper physiograph. We analyzed the % of activity, mean amplitude and motility index, by non parametric tests. No significant difference was observed between sexes. Difference or close to it were found for the groups with constipation, with or without diverticulosis, and for the latter in its subdivisions (localized, generalized and sigmoid diverticulitis). The rectal motor activity was similar in all groups. There was no difference for diverticulosis and its subdivision, when we take into account the several kinds of intestinal habits and the diverticula localization. The motility index averages showed low values for the sigmoid diverticulitis fact that suggests some dysfunction of this segment (hypocontractility). The key fa

[Use of isocolan in bowel preparation of patients with congestive heart failure]

The aim of this study was to verify the safety and effectiveness of a polyethylene-glycol electrolytes lavage solution (PEG-ELS) in patients with delicate fluid and electrolyte balance. Thirteen patients with chronic congestive heart failure (CHF) undergoing diagnostic colonoscopy, were asked to drink three liters of Isocolan (Bracco s.p.a.) at a rate of 500 ml/30 minutes, 8 hours before endoscopic examination. Plasma electrolytes (Na, K, C1), BUN, creatinine, glycemia, hematocrit, urine specific weight, arterial pressure, pulse rate, ECG and body weight were obtained before and after PEG-ELS supply. Colonic cleansing was judged by the same endoscopist as excellent, good or poor. Data, expressed as mean (SE), were analyzed by a two-tailed ranked test. PEG-ELS supply did not alter fluid and electrolyte balance, since no significant differences were found for all laboratory parameters studied. Out of the clinical features, diastolic arterial pressure significantly (p = 0.05) raised from 72.3 (3.0) to 78.8 (2.8) mmHg and body weight significantly (p = 0.007) increased from 70.7 (3.4) to 71.2 (3.4) kg. Colon cleansing resulted excellent in 8 patients and good in 5. This study shows that Isocolan proved to be safe in patients with CHF and that a slow drinking velocity do not impair adequate colon cleansing.
