Comparison of short- and long-term outcomes of laparoscopic-assisted total gastrectomy and open total gastrectomy in gastric cancer patients
Laparoscopy-assisted total gastrectomy (LATG) has been used more frequently despite the associated technical difficulty and concerns over oncological safety. This study was undertaken to compare the short- and long-term surgical outcomes following either LATG or open total gastrectomy (OTG) for gastric cancer.
A total of 120 LATG and 228 OTG were retrospectively matched with respect to sex, age (±5 years), and pathological tumor-node-metastasis stage for comparison of the clinical outcomes.
The total complication rate among 120 LATG and 228 OTG was 18.3 % (22/120) and 16.2 % (37/228), respectively. The most common complication after LATG was anastomotic-related complication (6.7 %); five anastomotic leakages (4.2 %) and three anastomotic strictures were reported (2.5 %). That after OTG was wound complication (3.5 %), including seroma or infection. Matched patients analysis: Time to first gas passing and time to the resumption of a soft diet were significantly shorter in the LATG group than in the OTG group. The postoperative hospital stay of LATG was shorter in the LATG group (9.3 ± 4.2 days) than in the OTG group (11.7 ± 7.3 days; p = 0.057). Among matched patients, there was no significant difference between complication rate (24 vs. 32 %; p = 0.504) or leakage rate (6 vs. 4 %). During median follow-up of 50 (range, 10–92) months, there was no significant difference in the disease-free survival rate between the matched groups, respectively (94.5 vs. 87.1 %: p = 0.148). As for patients with TNM stage I gastric cancer, the disease-free survival rate (100 vs. 90.9 %; p = 0.5) and the cumulative survival rate (91.5 vs. 95.2 %; p = 0.618) did not differ significantly between the LATG and OTG groups.
LATG for gastric cancer has the advantage over an OTG in terms of better short-term outcomes and similar long-term outcome. LATG is an acceptable alternative to OTG for the treatment of gastric cancer.
