We report a case of locally far-advanced colon cancer resected by laparoscopic surgery after colonic stent insertion and neoadjuvant chemotherapy. A 71-year-old man with obstructive symptoms was admitted to our hospital in July 2015. CT revealed a sigmoid colon tumor infiltrating the retroperitoneum and small intestine.

[Large bowel malignant obstruction treated with SEMS placement as a bridge to surgery procedure].

We treated 5 cases of preoperative decompression using the self-expandable metallic stent (SEMS) against obstructive left side colon cancer since October 2013. The obstruction site was the descending colon in one patient, sigmoid colon in 2, rectal-sigmoid colon in 1, and rectum in 1. Colonic stent placements were successful in all cases.

We report a unique extralobar pulmonary sequestration in the upper thoracic region with 3 aberrant vessels connecting to the right subclavian artery, right superior pulmonary vein, and right pulmonary artery in a 20-year-old man. The sequestered lung was completely excised using a video-assisted thoracoscopic approach.
