[Three Cases of Obstructive Left-Sided Colon Cancer Resected by Laparoscopic Surgery].

We report 3 cases of obstructive left-sided colon cancer that could be treated with laparoscopic resection.Case 1: A 25- year-old man was given a diagnosis of colonic obstruction due to transverse colon cancer.Twenty -four days after decompression by a nasointestinal tube, we performed a laparoscopic partial colectomy.Case 2: A 75-year-old woman was given a diagnosis of colonic obstruction due to sigmoid colon.Forty -nine days after decompression by a laparoscopic transverse colostomy, we performed a laparoscopic sigmoidectomy.Case 3: A 48-year-old man was given a diagnosis of colonic obstruction due to sigmoid colon cancer.Twenty -two days after decompression by colonic stent, we performed a laparoscopic sigmoidectomy.In these 3 cases, decompression was sufficient when resecting the primary lesions, and the operations could be completed laparoscopically.Elective radical surgery was possible by resolution of oncologic emergency state.
