Comparison of short-term efficacy between totally laparoscopic gastrectomy and laparoscopic assisted gastrectomy for elderly patients with gastric cancer

BACKGROUND Totally laparoscopic gastrectomy(TLG)entails both gastrectomy and gastrointestinal reconstruction under laparoscopy.Compared with laparoscopic assisted gastrectomy(LAG),TLG has been demonstrated in many studies to require a smaller surgical incision,result in a faster postoperative recovery and less pain and have comparable long-term efficacy,which has been a research hotspot in recent years.Whether TLG is equally safe and feasible for elderly patients remains unclear.AIM To compare the short-term efficacy of and quality of life(QOL)associated with TLG and LAG in elderly gastric cancer(GC)patients.METHODS The clinicopathological data of 462 elderly patients aged≥70 years who underwent LAG or TLG(including distal gastrectomy and total gastrectomy)between January 2017 and January 2022 at the Department of General Surgery,First Medical Center,Chinese PLA General Hospital were retrospectively collected.A total of 232 patients were in the LAG group,and 230 patients were in the TLG group.Basic patient information,clinicopathological characteristics,operation information and QOL data were collected to compare efficacy.Compared with those in the LAG group,intraoperative blood loss in the TLG group was significantly lower(P<0.001),and the time to first flatus and postoperative hospitalization time were significantly shorter(both P<0.001).The overall incidence of postoperative complications in the TLG group was significantly lower than that in the LAG group(P=0.01).Binary logistic regression results indicated that LAG and an operation time>220 min were independent risk factors for postoperative complications in elderly patients with GC(P<0.05).In terms of QOL,no statistically significant differences in various preoperative indicators were found between the LAG group and the LTG group(P>0.05).Compared with the laparoscopic-assisted total gastrectomy group,patients who received totally laparoscopic total gastrectomy had lower nausea and vomiting scores and higher satisfaction with their body image(P<0.05).Patients who underwent laparoscopic-assisted distal gastrectomy were more satisfied with their body image than patients in the totally laparoscopic distal gastrectomy group(P<0.05).CONCLUSION TLG is safe and feasible for elderly patients with GC and has outstanding advantages such as reducing intracorporeal blood loss,promoting postoperative recovery and improving QOL.
