“…In a study conducted by Aslina et al (13), it was found that the rate of reaching the cecum in females (92.7%) was lower than that in males (95.5%). As for the study by Anderson et al (14), it was determined that gender was not a factor related to failure.…”

Objective: Colonoscopy is a gold standard procedure for several colon pathologies. Successful colonoscopy means demonstration of the ileocecal valve and determination of colon polyps. Here we aimed to evaluate our colonoscopy success and results. Material and Methods:This retrospective descriptive study was performed in İstanbul Eren hospital endoscopy unit between 2012 and 2015. Colonoscopy results and patient demographics were obtained from the hospital database. All colonoscopy procedures were performed under general anesthesia and after full bowel preparation. Results:In all, 870 patients were included to the study. We reached to the cecum in 850 (97.8%) patients. We were unable to reach the cecum in patients who were old and obese and those with previous lower abdominal operations. Angulation, inability to move forward, and tortuous colon were the reasons for inability to reach the cecum. Total 203 polyp samplings were performed in 139 patients. We performed 1, 2, and 3 polypectomies in 97, 28, and 10 patients, respectively. There were 29 (3.3%) colorectal cancers in our series. There was no mortality or morbidity in our study. Conclusion:General anesthesia and full bowel preparation may be the reason for increased success of colonoscopy. Increased experience and patient-endoscopist cooperation increased the rate of cecum access and polyp resection and decreased the complication rate.

“…For example, the study with the shortest reported time to reach the cecum subtracted the time consumed with polyp removal before reaching the cecum. 22 At this time, more research is required to clarify these variables comparing colonoscopists and their procedure time.…”

Background: Colonoscopy is becoming increasingly necessary for many patients in screening, diagnosing, and treating colorectal problems. Because the majority of rural doctors are family physicians, providing colonoscopy for the enlarging group of patients with valid indications in rural areas is difficult, unless rural family physicians perform the procedure. Subspecialists in academic settings have been responsible for most of the previously reported studies regarding colonoscopy. We have studied the safety and efficacy of the procedure when performed by rural family physicians.Methods: A total of 200 sequential colonoscopies performed by family physicians in a rural setting were prospectively collected. Outcomes were measured based on current recommendations and benchmarks, including rate of reaching the cecum, time to reach the cecum, time to completion of the study, pathologic lesions found, and complications.Results: The rate of reaching the cecum was 96.5%, and the average time to the cecum was 15.9 minutes. The average time to study completion was 34.4 minutes. The rate of neoplastic polyps and cancer found was 22.5% and 2.5%, respectively. There were no serious complications.Conclusions

“…Patient factors that have been identified to be associated with insufficient colonoscopy are female sex, increasing patient age, diverticular disease, and history of abdominal surgery. Additional factors that have been reported are a low body mass index, history of constipation, or laxative use [17][18][19]. Much of endoscopy training is aimed at ourvercoming these unfavorable features so that all patients receive high-quality, safe colonoscopy.…”

An unmet medical need: Advances in endoscopic imaging of colorectal neoplasia

Gastrointestinal cancer is a major public health problem worldwide. Detection of early neoplastic lesions in gastrointestinal tract is essential for cure, because prognosis and survival are related to the size and stage of malignant lesions. Endoscopic screening and treatment of polyps could prevent approximately 80% of colorectal cancer (CRC). However, white‐light endoscopy is an imperfect technology since miss rates of up to 25% have been reported and polyps without malignant potential were treated without benefit but with additional costs and risks to the patient. There are several known “human” predictors of an inadequate colonoscopy. These include patient characteristics such as poor bowel preparation, female gender, or inpatient status. Skills of the endoscopists are also an important issue. Therefore, a variety of advanced technologies has been attempted to overcome these issues. These new endoscopic imaging techniques allow a more precise classification of mucosal alterations with selection of patients for invasive therapy or surveillance. Further, molecular and functional imaging techniques could identify novel targets for therapies and new prospects to access response to therapies. However, at the “end of the day” a better endoscopic approach for CRC screening and surveillance depends on a good bowel preparation, a trained endoscopist spending sufficient time on a detailed examination together with an advanced endoscope.
