Colonoscopy at King Hussein Medical Center; indications, effectiveness, safety and outcome

ABSTRACT

To find out the indications, effectiveness, safety and outcome of colonoscopy at King Hussein Medical Center. A retrospective analysis of the colonoscopy records for patients who underwent elective colonoscopy over a 7-year period [January 2000-October 2006] at King Hussein Medical Center in Amman, Jordan was done. Data collected included the number of the patients, age, gender, reason for doing the procedure, endoscopic findings, and any immediate complication. For all patients colonic preparation using Dulcolax [Biscodyl 5 mg tab] and Fortrans [Macrogol 4000-64 gm] or castor oil with normal saline and unistiffness endoscopes were used. Almost all colonoscopies were done with sedation using Mipiridine 25 mg and Midazolam 3 mg intravenously. A total of 3865 colonoscopies were included in the study, 42% percent of patients were aged less than 50 years. 89% of the colonoscopies were done for patients from physicians as outpatients and 11% for patients who were already in hospital. The number of endoscopies performed during the year 2006 per month was considerably higher [mean 65] than that done during the year 2000 [mean 30]. The main indications for colonoscopies were rectal bleeding [39%], constipation [17%], and diarrhea in 12%. In 3749 [97%] patients, the procedure was completed up to cecum. Normal colonoscopy was reported in 72.5% of patients. The most common abnormal findings were colonic cancer [29%], colonic polyps in 24% and inflammatory bowel disease in 16%. Other common findings were diverticulosis [13.4%], melanosis coli [2.4%], and vascular ectasias in 2.5%. Internal hemorrhoids was a coexistent finding in [n=30] those diagnosed as colonic cancer and [n=18] in those diagnosed as colonic polyps, but it was the only colonoscopic finding in 130 patients [12.2%]. Colonic polyps were also found as coexistent finding in 47 patients diagnosed as colonic cancer. Seven [0.018%] patients had a major complication related to the procedure in the form of colonic perforation [n=4], minor bleeding which did not necessitate blood transfusion [n=2], and stuck snare wire due to looping around a normal colonic mucosa that mandated removal by lapratomy [n=1]. Colonoscopy at King Hussein Medical Center, is safe and effective in establishing a definitive diagnosis, and rarely associated with major complications such as perforation or bleeding
