To investigate the safety and feasibility of two different surgical methods for patients with unresectable distal gastric cancer.

Clinical data of 61 patients with unresectable distal gastric cancer who underwent surgical treatment from September 2012 to September 2019 were analyzed retrospectively. Among them, 25 cases underwent modified Devine operation (modified group), and 36 cases underwent traditional gastrojejunostomy (traditional group). Statistical analysis were performed by using SPSS21.0 software package. The perioperative indicators were expressed as (±s) and were analyzed by using independent sample t-test. The postoperative complications were compared by using χ² test. The postoperative satisfaction of patients were compared by using Mann-Whitney U test. A P value of <0.05 was considered as statistically significant difference.

There were no significant difference between two groups, in terms of the average operation time, blood loss, postoperative ventilation time, eating time, hospitalization time and ALB increase at 1 month after operation (P>0.05). There were 6 cases (16.7%) of gastric emptying disorder in the traditional group, while no gastric emptying disorder occurred in the modified group, with statistically significant difference (P=0.032). The total postoperative complication rate of 4.0% in the improved group was significantly lower than 22.2% in the traditional group, with statistically significant difference (P=0.048). The postoperative satisfaction of patients in improved group was signifcantly high than that in traditional group, with statistically significant difference (P=0.016).

Modified Devine operation could significantly relieve the symptoms and reduce the postoperative complications and improve satisfaction. It is a safe and effective surgical method, which is worthy of promotion and application.
