ObjectiveTo investigate the feasibility of totally laparoscopic distal gastrectomy (TLDG) based on delta-shaped gastroduodenostomy in the treatment of gastric cancer. MethodsNinety patients with gastric cancer who treated in our hospital from December 2013 to December 2015 were retrospectively analyzed. Forty-five patients with gastric cancer received delta-shaped gastroduodenostomy by using laparoscopic linear stapler after they were treated with TLDG and D2 lymphadenectomy (TLDG group), while 45 patients with gastric cancer received laparoscopic assisted distal gastrectomy (LADG) and D2 lymphadenectomy (LADG group). The operative time, digestive tract reconstruction time, blood loss, number of dissected lymph nodes, length of proximal and distal margin to the cancer, time of the first flatus, recovery time of drinking water, time of resuming semi-fluid diet, postoperative hospital stay, and complications during follow-up period were observed and evaluated. Results① Intraoperative findings. The operative time, digestive tract reconstruction time, and length of distal margin to the cancer of TLDG group were significantly longer than those corresponding index of LADG group (P < 0.050), but the blood loss was significantly less than that of LADG group (P < 0.050). There was no significant difference between two groups in proximal margin to the cancer and number of dissected lymph nodes (P > 0.050). ② Postoperative findings. There was no significant difference between two groups in time of the first flatus, recovery time of drinking water, time of resuming semi-fluid diet, postoperative hospital stay, and incidence of complication (P > 0.050). All patients were followed for 6-16 months (median with 10 months), and there was no one suffered from recurrence, anastomotic stricture, and anastomotic obstruction. ConclusionThe TLDG based on delta-shaped gastroduodenostomy in the treatment of gastric cancer was feasible and safe, and it will be an ideal method for digestive tract reconstruction in patients with gastric cancer, so it is worthy to clinical application.
