Laparoscopic resection of rectal cancer or gastric cancer has been advocated for the benefits of a reduced morbidity,a shorter treatment time,and similar outcomes.However,simultaneous laparoscopy-assisted low anterior resection and distal gastrectomy for synchronous carcinoma of rectum and stomach are rarely documented in literature.Endoscopic examination revealed a synchronous carcinoma of rectum and stomach in a 55-year-old male patient with rectal bleeding and epigastric discomfort.He underwent a simultaneous laparoscopy-assisted low anterior resection and distal gastrectomy with regional lymph nodes dissected.The operation time was 270min and the estimated blood loss was 120mL.The patient required parenteral analgesia for less than 24h.Flatus was passed on postoperative day 3,and a solid diet was resumed on postoperative day 7.He was discharged on postoperative day 13.With the advances in laparoscopic technology and experience,simultaneous resection is an attractive alternative to a synchronous gastrointestinal cancer.
