Abstract    Injury to the superior mesenteric plexus may occur during D3 resection of right colon cancer，which has not attracted the attention of surgeons and patients because there are no specific symptoms. The innervation of the right colon is dual，including the extrinsic nervous system and the intramural nervous system，which together regulate the movement，absorption and secretion of the right colon. The symptoms of diarrhea，abdominal pain，and increased defecation frequency after D3 resection of right colon cancer may be related to the excessive dissection of lymph nodes during the operation，resulting in damage to the superior mesenteric plexus. Moderate dissection based on accurate preoperative tumor staging and lymph node dissection based on nerve fiber tissue dissection can effectively avoid nerve damage and reduce postoperative symptoms caused by intestinal autonomic dysfunction.

Key words: right colectomy, superior mesenteric plexus, neuroprotection
