“…Colonoscopy is a gold standard in the evaluation of colonic diseases with increasing popularity from the 1970s to its eventual recommendation as a primary screening test for colorectal cancer in 1997 [68][69][70][71]. Although this procedure was available in other climes, many African countries did not keep pace with its usage from the onset [68].…”

Background: There is need to ascertain any epidemiologic shift of diverticulosis among Africans with traditionally high fiber diet consumption patterns and rare diverticulosis prevalence. Methods: We systematically searched PubMed, Scopus, Cochrane Library, African Journal Online (AJOL) and Google Scholar. Eligibility criteria included full text observational and experimental human colonoscopy studies on asymptomatic and symptomatic African population from 1985-2022. Case reports, conference abstracts, dissertations, systematic reviews, and studies lacking colonoscopy findings were excluded. NIH quality assessment tool for observational cohort and cross-sectional studies was used to assess risk of bias. Meta-analysis was performed using the random-effect model. Heterogeneity was assessed using inconsistency (I2) statistics. Results: Thirty studies were included. Pooled prevalence rate of colonic diverticulosis was 9.1% (95%CI 7.1-11.2; I2=96.3%) with highest regional prevalence rate in West African studies at 11.3% (95%CI 7.6-14.9; I2=96.2%). Proportion of individuals with diverticulosis ≥50 years and male sex were 86.9 % (95%CI 80.5-92.1) and 65.2% (95%CI 55.0-74.8), respectively. Left colon had the highest diverticulosis frequency [37% (148/400)]. Bleeding/inflammation complications were sparingly detected [OR 0.2 (95%CI 0.03-0.75;p<0.0001)]. Conclusion: Colonic diverticulosis was most common in males aged >50. Left was colon predominantly affected. Regional variation in detection of diverticulosis was reported across Africa.

Colonic polyps are predominantly benign epithelial hyperplasias, adenomas, hamartomas or of inflammatory origin. There seems to be no transition between hyperplastic and adenomatous polyps. The tendency of adenomatous polyps to become malignant is still debated, differences between adenomatous and villous polyps do not exist. The proportion of villous adenomas and carcinomatous polyps increases with increasing diameter of the polyp. The histological pattern of colonic polyps is not always uniform: a sufficient judgement is only possible by serial section of the entire polyp. A polyp is on clinical grounds only malignant when the invasive growth has penetrated the muscularis mucosae. The new developed coloscopic polypectomy is possible with reasonable risk in all segments of the colon. It seems so that this method is becoming the treatEndoscopy 4 (1972) 212-216 0 Georg Thieme Verlag, Stuttgart

“… 13 The addition of insufflation, suction and instrument channels with a second fibreoptic cable for light transmission and a four-way deflectable tip, controlled by antagonistic cables running down the endoscope, resulted in the Olympus colonoscope in 1970. 14 Miniaturisation of a charged couple device allowed Welch Allyn to release the first video endoscope in 1983, closely resembling the endoscope we are familiar with today. 15 …”

Lower gastrointestinal endoscopy has evolved over time, fulfilling a widening diagnostic and therapeutic remit. As our understanding of colorectal cancer and its prevention has improved, endoscopy has progressed with improved diagnostic technologies and advancing endoscopic therapies. Despite this, the fundamental design of the endoscope has remained similar since its inception. This review presents the important role lower gastrointestinal endoscopy serves in the prevention of colorectal cancer and the desirable characteristics of the endoscope that would enhance this. A brief history of the endoscope is presented. Current and future robotic endoscopic platforms, which may fulfil these desirable characteristics, are discussed. The incorporation of new technologies from allied scientific disciplines will help the endoscope fulfil its maximum potential in preventing the increasing global burden of colorectal cancer. There are a number of endoscopic platforms under development, which show significant promise.
