Surgical Aspects of Lower Gastrointestinal Cancers

This chapter talks about several case studies for lower gastrointestinal cancers. The first case study is about a 65-year-old healthy female patient presents with a nonobstructing sigmoid colon adenocarcinoma found on screening colonoscopy . A few other case studies include a 59-year-old male patient presents with a 3 cm adenocarcinoma at 8 cm from the dentate line. A metastatic work-up demonstrates no evidence of disease outside the rectum. Ultrasound demonstrates an uT3N0Mx primary lesion, and on magnetic resonance imaging (MRI), the closest margin is 7 mm from the fascia propria of the rectum. The chapter presents with questions and answers for lower gastrointestinal cancers.
