[Combination of self-expandable metallic stent insertion and laparoscopic surgery as a less invasive treatment of obstructive left-sided colon cancer].

The purpose of this study was to evaluate the outcome of treating obstructive left-sided colon cancer with a combination of self-expandable metallic stent (SEMS) insertion and laparoscopic surgery. Ten patients were included in this study. Two patients had obstructive transverse colon cancer, and eight had obstructive sigmoid colon cancer. The patients had a SEMS inserted preoperatively as a bridge to surgery. Efficient decompression was achieved in all the patients, without any complications. Normal oral intake was possible until the laparoscopic, or laparoscope-assisted, one-stage radical operation. The SEMS insertion did not affect the surgical maneuver or laparoscopic operation at all. None of the patients developed any postoperative complications. After surgery, five patients were diagnosed with Stage II disease and three patients were diagnosed with Stage IIIA disease. The remaining two patients had distant metastasis (para-aortic lymph node and liver) and were diagnosed with Stage IV disease. Chemotherapy was administered to the two patients with Stage IV disease after a comparatively early recovery from a less invasive surgical procedure. SEMS insertion appears to be an effective, less invasive decompression method. When used in combination with laparoscopic surgery, SEMS insertion appears to be a safe and less invasive method of treating obstructive left-sided colon cancer.
