Laparoscopy-assisted combined resection for synchronous gastrointestinal multiple primary cancers

Background: Synchronous gastrointestinal multiple primary cancers ( SGMPC) is infrequent. This study aimed to investigate the feasibility and outcomes of laparoscopy- assisted combined resection for SGMPC. Material and methods: We retrospectively reviewed 16 cases of SGMPC underwent either open or laparoscopy- assisted combined resection in the Third Affiliated Hospital of Sun Yat- sen University from Jan. 2005 to Jan. 2014. Results: Sixteen cases contained synchronous colon cancers ( n 10), gastric and rectal cancer ( n 5), gastric and duodenal cancer ( n 1). Either laparoscopy- assisted or open procedure was performed. Compared with the open group, the laparoscopy group presented less blood loss ( 77.1 46.3 ml vs. 145.0 75.9 ml, P 0.047) and shorter incision length ( 5.2 0.7 cm vs. 16.4 1.9 cm, P 0.000), while no differences in operative time ( 228.3 38.8 min vs. 188.8 47.7 min, P > 0.05) and postoperative hospital stay ( 10.0 3.4 days vs. 12.0 4.8 days, P > 0.05). Two cases of postoperative complications occurred in the open group and one case of incision infection occurred in the laparoscopy one. Upon follow- up, 2 cases of open group ( 50.0%) and 8 cases of laparoscopy group ( 66.7%) were under status of disease free survival. Conclusions: Laparoscopy- assisted combined resection for SGMPC is feasible, safe and effective. c 2015 Surgical Associates Ltd. Published by Elsevier Ltd. All rights reserved.
