Introduction:
The incidence of remnant gastric cancer is increasing because of past use of subtotal gastrectomy to treat peptic ulcer and increased survival rates after radical gastrectomy for gastric cancer. The feasibility and advantages of laparoscopic total gastrectomy (LTG) for remnant gastric cancer remain unclear. Therefore, we aimed to investigate the safety, feasibility, and clinical short-term outcomes of LTG for remnant gastric cancer.
Methods:
Patients who underwent completion total gastrectomy for remnant gastric cancer between April 2007 and October 2017 were divided into two groups: the open total gastrectomy (OTG) group and the LTG group. Clinicopathological data and short-term outcomes were analyzed.
Results:
A total of 31 remnant gastrectomies (23 OTG, 8 LTG) were performed. Blood loss was significantly lower in the LTG group than in the OTG group (135.5 vs 568.3 mL, P = 0.013). However, there was no significant difference in the operation time, days to food intake, or length of hospital stay between the two groups. Additionally, there was no significant difference in the postoperative complications, number of retrieved lymph nodes, or pathological findings. Two LTG patients (25.0%) required conversion to open surgery. There was no mortality in either group.
Conclusions:
LTG for remnant gastric cancer can be a safe treatment option and may have an advantage of less blood loss than OTG.
