Background We have improved and named a new reverse rolling-mat type lymph node dissection, which effectively solves the dilemma faced by the traditional lymph node dissection in hand-assisted laparoscopic D2 radical gastrectomy through the optimization of the surgical procedure. However, the relevant clinical data are still scarce. The study aims to compare the clinical effects of two surgical procedure and explore the safety and feasibility of “reverse procedure”. Study design The clinicopathological data of 195 patients who underwent hand-assisted D2 radical total gastrectomy (HALTG) in our hospital from January 2011 to September 2017 were collected. A retrospective case–control study was used to compare the clinical outcomes of the two patterns of lymph node dissection. Among them, 89 patients underwent “cabbage type” lymph node dissection and 106 patients underwent the “reverse procedure” lymph node dissection. Results There were no significant differences between the two groups of patients in terms of gender, age, tumor location, incision length, postoperative hospitalization duration, pathological classification, recent complications, long-term recurrence and metastasis. The operation time of “cabbage type” group was shorter than that of “reverse procedure” group (178.35 ± 31.52 min vs 191.25 ± 32.77 min;  P  = 0.006). While, in the “reverse procedure” group, intraoperative blood loss was less (249.4 ± 143.12 vs 213.58 ± 101.43;  P  = 0.049), and there were more numbers of lymph nodes dissected (18.04 ± 7.00 vs 32.25 ± 14.23;  P  &lt; 0.001). Conclusion The pattern of reverse rolling-mat type lymph node dissection in HALTG perform well in terms of safety and feasibility.
