RESUMO
BACKGROUND: Participation in Colorectal cancer (CRC) screening programs is low in Saudi Arabia. Public awareness of CRC and knowledge of available screening tools are crucial for improving screening uptake. This study aimed to examine the level of awareness and knowledge of CRC among the Saudi population. MATERIALS AND METHODS: A survey-based study was conducted on 1912 residents of Riyadh, Saudi Arabia. The survey comprised 20 questions; these concerned the definition of the colon and rectum; the function of the colon; the incidence, risk factors, symptoms, screening methods, prevention methods, and treatment methods for CRC; and the value of early detection of CRC. RESULTS: Of the 1912 participants who completed the survey, only 51.7% knew that the colon was the large intestine, while 57% knew that the rectum was the end of the large intestine. Colonoscopy was the preferred screening tool (72.8%). Most respondents believed early detection of CRC through colonoscopy is associated with high survival rates. However, 65.7% of the participants reported that they would not like to undergo a CRC screening. Higher education level was also associated with knowledge that CRC can develop asymptomatically, with postgraduates most likely to know this (P = 0.032). CONCLUSIONS: There is a lack of knowledge regarding CRC among certain demographic groups in Saudi Arabia, and education and screening programs should target populations with the most limited knowledge.
RESUMO
BACKGROUND: Self-expanding metal stents (SEMS) are used as a bridge to surgery for colon cancer patients as an alternative to emergency surgery. Currently, there is a paucity of literature from Saudi Arabia on the preoperative usage of SEMS. OBJECTIVE: Determine whether SEMS are associated with a higher rate of complications. DESIGN: Retrospective cohort study SETTINGS: Tertiary care hospital in Saudi Arabia. PATIENTS AND METHODS: In patients diagnosed with obstructing colon cancer, up-front surgical resection was compared with insertion of SEMS followed by surgical resection between the years 2009 and 2013. MAIN OUTCOME MEASURES: Rate of stent-related short-term complications. Secondary endpoint, postoperative complications. SAMPLE SIZE: 65. RESULTS: Twenty-four (36.9%) patients underwent SEMS placement; 41 (63.1%) underwent primary surgery. The median (interquartile range) hospital stay was significantly higher among the SEMS group (13 [8.5] days versus 7 [3] days in the primary surgery group, P<.001). Five patients (20.8%) in the SEMS group developed complications: 2 (8.3%) perforations, 2 (8.3%) obstructions, and 1 (4.2%) stent migrations. CONCLUSION: SEMS is associated with longer hospital stays and short-term serious complications. Further research should be conducted, preferably with a larger sample size. LIMITATIONS: Retrospective design, small sample size. CONFLICT OF INTEREST: None.
