Surgical Management of Colon Cancer

摘要: Surgery remains the primary treatment modality for colon cancer. Prior to surgery, all patients should be clinically staged with a total exam; computed tomography scanning of chest, abdomen, and pelvis; measurement serum CEA level. The principles surgical resection cancer include four components. First, its mesentery resected along planes keep fascia intact. Second, vessel segment ligated at origin. Third, wide mesenteric performed ensure harvest least 12 lymph nodes. Finally, tumor 5 cm distal or proximal margin. Resection can approached either open laparoscopically. Clinical Outcomes Surgical Therapy Study Group (COST), Conventional versus Laparscopic-Assisted in Colorectal Cancer (CLASICC), COlorectal Laparoscopic Open (COLOR) trials demonstrated that laparoscopic approach was not inferior cancers. There are several technical approaches resecting right- left-sided cancers, which medial lateral, lateral medial, posterior, superior respectively. management obstructing perforated cancers presents unique challenges. provides most effective obstruction.
