Laparoscopic surgery for gastric cancer: comparative-effectiveness research and future trends

Recovery after laparoscopic right hemicolectomy for colon cancer

“…Laparoscopic surgery not only for colon cancer but also for rectal cancer is rapidly and increasingly used, at least among high-volume surgeons and hospitals, improving short-term outcomes [4][5][6][7][8][9][10]. However, improvement of long-term survival remains a challenge.…”

Assessing superiority: intracorporeal versus extracorporeal anastomosis for laparoscopic colon resection

“…Although the level of evidence is still not as high as for colectomy, the findings in favor of laparoscopic surgery for other gastrointestinal cancers, including rectal cancer and gastric cancer, are encouraging [4][5][6][7][8][9].…”

“…Despite rapid advances in improving short-term outcomes by using the latest laparoscopic or robotic technology for patients with solid cancers [3][4][5][6][7][8][9], the big challenge is how to improve long-term survival or even cure these patients particularly when diagnosis is late at advanced stages of disease. Advances in cancer biology and molecular oncology and the advent of next-generation sequencing technology provide now promises for new therapeutic strategies, including both new robust biomarkers for selecting the right patients and novel targeted drugs.…”

Nonepithelial, submucosal gastric tumors: is laparoscopic wedge resection the optimal treatment?

“…Although the high level of evidence supporting laparoscopic colectomy or laparoscopic rectal resection for adenocarcinoma has not been reached for laparoscopic gastrectomy [2][3][4], reports on the superiority of laparoscopic D2 gastrectomy for gastric cancer, particularly from Asian countries, are very promising [5][6][7][8][9].…”

“…Once recent evidence suggests that extended lymphadenectomy provides an overall survival benefit for gastric cancer patients with resectable tumors [10,11], D2 lymphadenectomy will be recommended also for laparoscopic surgery [5]. However, D2 lymph node dissection during laparoscopic gastrectomy is a demanding procedure performed appropriately only in specialized institutions according to data analysis in a recent editorial [5].…”
