Abstract
139 Background: In patients with locally advanced gastric cancer, total gastrectomy with splenectomy (TGS) is sometimes indicated when a tumor directly infiltrates the spleen or obvious splenic hilar lymph node metastasis exists. However, this procedure is technically demanding and can cause potentially fatal postoperative pancreas-related complications. TGS has increasingly been performed laparoscopically, particularly in East Asia. However, the number of reports regarding laparoscopic TGS (LTGS) is limited, and thus the feasibility of LTGS remains unclear. Methods: The present study included 68 patients with upper-third advanced gastric cancer who underwent LTGS or conventional open TGS (OTGS) between 2012 and 2018. Clinicopathological characteristics and surgical outcomes were retrospectively reviewed and compared between the groups. Results: There were no significant differences in sex, age, tumor size, cN factor, or cStage. cT4 was less frequently included in the LTGS group (21.4 vs 79.6 %, P < 0.01). In the LTGS group, operating time was longer (332 vs 247 min, P < 0.01) and blood loss was less (38 vs 598 ml, P < 0.01). Incidence of Clavien-Dindo grade 3 or higher complication (0 vs 24.1 %, P = 0.05) and median postoperative hospital stay (9 vs 11 days, P = 0.03) were significantly difference between the groups. The median number of harvested No. 10 and No.11d lymph nodes was equivalent between the groups. Conclusions: LTGS can be a safe procedure provided an experienced surgical team performs the surgery. Oncological safety remains unclear, and needs to be confirmed in future trials.
