Objective: To investigate the clinical efficacy of Da Vinci robotic total gastrectomy combined with spleen-preserving splenic hilar lymphadenectomy for gastric cancer. Methods: The retrospective cross-sectional study was conducted. The clinicopathological data of 47 patients with gastric cancer who were admitted to Fujian Medical University Union Hospital from September 2016 to June 2018 were collected. There were 37 males and 10 females, aged from 23 to 75 years, with an average age of 60 years. Patients underwent Da Vinci robotic total gastrectomy combined with spleen-preserving splenic hilar lymphadenectomy. Observation indicators: (1) intraoperative situations; (2) postoperative situations; (3) postoperative pathological examination; (4) follow-up. Follow-up was conducted by outpatient examination and telephone interview to detect postoperative survival of patients up to September 2018. Measurement data with normal distribution were represented as Mean±SD, and measurement data with skewed distribution were expressed by M (range). Count data were represented as absolute numbers. Results: (1) Intraoperative situations: 47 patients underwent Da Vinci robotic total gastrectomy combined with spleen-preserving splenic hilar lymphadenectomy for gastric cancer, without conversion to open surgery. The operation time, hilar lymph node dissection time, volume of intraoperative blood loss, number of lymph node dissected, number of splenic hilar lymph node dissected, number of metastatic lymph nodes, number of metastatic splenic hilar lymph node were (225±36) minutes, (20±6) minutes, (40±27) mL, 40 (range, 17-112), 2 (range, 0-10), 2 (range, 0-29), 0 (range, 0-3). (2) Postoperative situations: time to first out-of-bed activities, time to first anal flatus, time to gastric tube removal, time to initial liquid diet intake, time to initial semi-liquid diet intake, time to drainage tube removal, and duration of postoperative hospital stay were (2.0±0.3)days, (3.4±0.9)days, (3.4±1.1)days, (4.8±1.0)days, (6.7±1.5)days, (8.5±2.5)days, and (12.0±8.3)days, respectively. Of 47 patients, 3, 2, 1, 1, and 1 were detected pulmonary infection, abdominal bleeding, anastomotic fistula, postoperative intestinal obstruction, and abdominal infection. There were 1, 5, and 2 patients with complications in grade Ⅰ, Ⅱ, and Ⅲ of Clavien-Dindo classification. There was no death in the postoperative 30 days. Two patients with abdominal bleeding were cured by intervene therapy, and patients with other complications were cured by conservative treatment. (3) Postoperative pathological examination: tumor diameter, cases with nodal or vascular or neural invasion, cases with differentiated and undifferentiated tumor (histological differentiation), cases in T1, T2, T3, T4 stages (T staging), cases in N0, N1, N2, N3 stages (N staging), cases in Ⅰ, Ⅱ, Ⅲ stages (TNM staging) were (4.2±1.6)cm, 26, 31, 16, 5, 22, 17, 3, 18, 9, 8, 12, 13, 20, 14, respectively. (4) Follow-up: 47 patients were followed up for 3-25 months, with a median time of 9 months. During the follow-up, 3 of 47 patients died of tumor recurrence, 1 had tumor-bearing survival, and 43 had tumor-free survival. Conclusion Da Vinci robotic total gastrectomy combined with spleen-preserving splenic hilar lymphadenectomy for gastric cancer is safe and feasible.

Objective:To investigate the clinical efficacy of Later-cut overlap anastomosis versus Roux-en-Y anastomosis in laparoscopic total gastrectomy.Methods:The propensity score matching and retrospective cohort study was conducted. The clinicopathological data of 1 804 patients with gastric cancer who underwent laparoscopic total gastrectomy in Fujian Medical University Union Hospital from January 2014 to March 2019 were collected. There were 1 346 males and 458 females, aged from 18 to 91 years, with a median age of 63 years. Of 1 804 patients, 100 undergoing Later-cut overlap anastomosis for digestive tract reconstruction in totally laparoscopic total gastrectomy and 1 704 undergoing Roux-en-Y anastomosis in laparoscopic-assisted total gastrectomy were allocated into modified group and traditional group, respectively. Observation indicators: (1) the propensity score matching conditions and comparison of general data between the two groups after propensity score matching; (2) intraoperative and postoperative situations; (3) complications; (4) follow-up, including ① functional scales of European Organization for Research and Treatment of Cancer quality of life questionnaire-core 30 (EORTC-QLQ-C30) for two groups after propensity score matching, ② symptom scales of EORTC-QLQ-C30 for two groups after propensity score matching, ③ symptom scales of European Organization for Research and Treatment of Cancer quality of life questionnaire of stomach 22 (EORTC-QLQ-STO22) for two groups after propensity score matching, ④ subgroup analysis; (5) learning curve of Later-cut overlap anastomosis. Patients were followed up by outpatient examination, paying a visit, Email and telephone interview once every 3 months within postoperative 2 years and once every 6 months within postoperative 3-5 years to detect postoperative life quality up to December 2019. The propensity score matching was conducted by 1∶1 matching using the nearest neighbor method. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was done using the t test. Count data were represented as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test. Comparison of ordinal data between groups was analyzed using the nonparametric rank sum test. Measurement data with skewed distribution were represented as M ( P25, P75) or M (range), and comparison between groups was done using the U test. The cumulative sum curve was used to analysis minor changes between individual and overall data, with the equation of CUSUM=∑ n,i=1 ( x i- μ), x i as esophagojejunostomy time of individuals, μ as the average time of esophagojejunostomy, n as serial number of patients.
