AIM: To evaluate the feasibility and short-term efficacy of laparoscopic spleen-preserving splenic hilar(No. 10) lymphadenectomy to treat advanced upper gastric cancer(AUGC).METHODS: Between January and December 2012, 108 laparoscopic spleen-preserving No. 10 lymphadenectomy along with total gastrectomy with routine D2 lymphadenectomy were performed consecutively at our hospital to treat clinical T2-3(cT2-3) upper gastric cancers. The preoperative clinical T stage was cT2 in 36 patients and cT3 in 72 patients. A prospectively designed database tracked the 108 patients, including the completeness of their medical records and the adequacy of follow-up. Patient clinicopathological char-acteristics, intraoperative and postoperative surgical outcomes, morbidity and mortality, lymph node(LN) dissection, and postoperative follow-up were analysed retrospectively.RESULTS: Laparoscopic spleen-preserving No. 10 lymphadenectomy was successful in all 108 patients. The mean operation time was 169.3 ± 27.1 min, and the mean No. 10 lymphadenectomy time was 20.0 ± 5.7 min. The mean total blood loss was 46.2 ± 11.3 mL, and the mean blood loss from No. 10 lymphadenectomy was 14.3 ± 3.8 mL. The mean postoperative hospital stay was 11.9 ± 6.0 d. The intraoperative and postoperative morbidity rates were 3.7% and 12.0%, respectively; however, there was no postoperative mortality. A mean of 44.4 ± 17.6 LNs were retrieved from each specimen, including 3.0 ± 2.4 No. 10 LNs. Three patients(2.8%) with cT3 cancer had LN metastasis of the splenic hilus, including two patients with pathological T3(pT3) and one patient with pathological T4a(pT4a) tumours, all located in the greater curvature. No splenic hilar LNs metastasis was evident in the patients with pT1 and pT2 tumours. At a median follow-up time of 18 mo(range, 12 to 23 mo), all patients were alive and none had experienced recurrent or metastatic disease.CONCLUSION: Laparoscopic spleen-preserving No. 10 lymphadenectomy is feasible and effective to treat AUGC.
