Disease relevance of Colonoscopes

• This study was designed to report our experience using a high-resolution colonoscope combined with indigo carmine dye to diagnosis diminutive colorectal polyps [1].
• BACKGROUND: An outbreak of hemorrhagic proctocolitis occurred after the introduction of 2% glutaraldehyde as a disinfectant for colonoscopes [2].

High impact information on Colonoscopes

• For the subsequent 48 patients, those requiring treatment received therapy, such as epinephrine injections or bipolar coagulation, through the colonoscope [3].
• In study 1, we randomized 104 adult patients with intact colons to undergo colonoscopy with a standard pediatric colonoscope (Olympus PCF-160), a prototype pediatric colonoscope with short bending in four directions (PCF-AYL), or a prototype pediatric colonoscope with short bending in two directions, and normal bending in two directions (PCF-AY3L) [4].
• One patient was successfully treated with glycerin and saline enema through a fiberoptic colonoscope placed in the ascending colon [5].
• The equation F=F MAX-P TIP/R was used to graph flow values (F) from the maximum measured flow (F MAX), the calculated resistance to air flow offered by the colonoscope (R), and the air pressure observed at the colonoscope tip (P TIP ) [6].
• Group A (n = 125) received midazolam, 0.07 mg/kg intravenously plus meperidine, 0.77 mg/kg intravenously immediately preceding the colonoscope insertion [7].

Anatomical context of Colonoscopes

• A new approach to the observation of minute changes of the colonic mucosa by means of magnifying colonoscope, type CF-MB-M (Olympus) [8].
• CONCLUSIONS: The pediatric colonoscope, and particularly the newer Olympus PCF-100 colonoscope, is very useful in adult patients in whom it is not possible to traverse a fixed, angulated sigmoid colon or stricture using the standard adult colonoscope [9].
• PATIENTS AND METHODS: The variable-stiffness colonoscope (Olympus America XPCF-140AL) was used by the same examiner to reattempt colonoscopy immediately in all patients in whom colonoscopy to the cecum with the standard colonoscope was incomplete [10].

Associations of Colonoscopes with chemical compounds

• A 0.2% indigocarmine solution was sprayed, and the colonoscope zoom apparatus performed a magnified observation after an ordinary colonoscopy identified the lesions [11].
• The colonoscope was passed through 1 of 16 study arms (5 reps/arm for a total of 80 runs) that were controlled for all possible combinations of the following variables: manual precleaning; 10-, 20-, or 45-minute glutaraldehyde exposure; air or ethanol drying; or automated reprocessing with peracetic acid (liquid sterilization system) [12].
• METHODS: Each patient in the treated group (n = 409) was given approximately 200 mL of the solution (a mixture of 8 mL of peppermint oil and 0.2 mL of Tween 80 per 1 L of water with 0.04% indigo carmine) by using a hand pump attached to the accessory channel of the colonoscope [13].
• DESIGN: Suction channels from 10 each of bronchoscopes, duodenoscopes used for endoscopic retrograde cholangiopancreatography, and colonoscopes were assessed immediately after patient use for the levels of bilirubin, hemoglobin, protein, sodium ion, carbohydrate, endotoxin, and viable bacteria [14].
• In each case 0.5 to 1 cm3 of isosulfan blue dye was injected submucosally via the colonoscope [15].

Gene context of Colonoscopes

• MATERIALS AND METHODS: One hundred forty patients were randomly allocated for screening with a normal colonoscope (NCF) or that with the cap-fitted colonoscope (CCF) [16].
• In a second study (Study 2) 90 sedated patients undergoing colonoscopy were randomized to receive 1 mg glucagon (n = 46) or placebo (n = 44), intravenously, just before colonoscope insertion [17].
• Although individuals may have a 30% daily fluctuation in serum values, this study detected no significant change in serum PSA levels after prolonged transrectal prostatic manipulation with a colonoscope [18].
• The majority of cases of per rectal haemorrhage (PRH) are due to colorectal causes within the diagnostic reach of the colonoscope [19].
• Our method uses combined video images originating from the laparoscope, an overview CCD camera placed in the operating theatre and, when available, a video colonoscope [20].

Analytical, diagnostic and therapeutic context of Colonoscopes

• Fibre-endoscopy of the ileal conduits was performed with the Olympus short colonoscope [21].
