Background  Laparoscopic spleen-preserving Splenic hilar lymphadenectomy (LSPL) is required in laparoscopy-assisted total gastrectomy for advanced proximal gastric cancer. However, it is considerably difficult and risk in clinical practice. Thus, we explore the application of LSPL performed by following the perigastric fascias and the intrafascial space in D2 radical gastrectomy for advanced upper-third gastric cancer.    Methods  From July 2010 to December 2012, 109 patients with T2–3 upper-third gastric cancer underwent LSPL. Of these patients, 55 underwent classic LSPL (classic group), and the remaining 54 patients underwent LSPL performed by following the fascias and intrafascial space (fascia group). Clinicopathologic characteristics and intraoperative and postoperative variables were compared between the two groups.    Results  There were no significant differences in clinicopathological characteristics between the two groups (P>0.05). All of the operations were successful without conversion to laparotomy. The operation time, mean splenic hilar lymph node (LN) dissection time, mean total blood loss and mean blood loss from splenic hilar LN dissection were significantly lower in the fascia group than in the classic group (P<0.05), whereas the times to first flatus, fluid diet and soft diet and the duration of hospital stay were similar in both groups. The mean number of harvested LNs (No. 10 and No. 11d) was slightly higher in the fascia group, but the difference was not significant. No significant difference in morbidity was found between the fascia group and the classic group (9.3% vs.10.9%, P>0.05). At a median follow-up of 12 months(range 5 to 35 months), none of the patients had died or experienced recurrent or metastatic disease.    Conclusion  LSPL performed by following the fascias and intrafascial space is an optimal and safe technique based on anatomical logic, and it reduces the difficulties associated with LSPL, making it easier to master and allowing its widespread adoption.
