Video Summary

The lecture covers gastrointestinal cancers focusing primarily on colorectal cancer, its prevalence, risk factors, and importance of early screening starting at age 45. Screening includes colonoscopy and non-invasive tests like FIT, emphasizing follow-up colonoscopy if positive. Colorectal cancer can present asymptomatically or with symptoms like weight loss and rectal bleeding, and staging guides treatment options including surgery and chemotherapy. Lower GI bleeding causes range from malignancy and diverticular bleeding to hemorrhoids and ischemic colitis. Management involves resuscitation, diagnosis (often via colonoscopy or CT angiography), and interventions such as clipping, banding, or argon plasma coagulation. Diverticulosis is common, especially in older adults, and can lead to inflammation (diverticulitis) or painless bleeding (diverticular bleeding). Diverticulitis is now often managed conservatively without antibiotics. Hemorrhoids, a common benign cause of bleeding, are classified as internal or external, with treatments including conservative management, rubber band ligation, or surgery in severe cases. Overall, early detection and tailored treatment improve outcomes in GI diseases.
