Abstract:
Objective To investigate the application value of different digestive tract reconstruction methods in laparoscopic distal gastrectomy (LDG).Methods The retrospective cohort study was conducted.The clinicopathological data of 164 with early gastric cancer (GC) who were admitted to the First Affiliated Hospital of Fujian Medical University between June 2010 and April 2015 were collected.Of 164 patients undergoing LDG,45 receiving Billroth Ⅰ (B Ⅰ) anastomosis,39 receiving Billroth Ⅱ (B Ⅱ) anastomosis,44 receiving Roux-en-Y anastomosis and 36 receiving uncut Roux-en-Y anastomosis were allocated into the B Ⅰ group,B Ⅱ group,RY group and uncut RY group,respectively.Observation indicators:(1) surgical and postoperative recovery situations;(2) postoperative short-term complications situations;(3) follow-up situations.Follow-up using outpatient examination and telephone interview was performed to detect postoperative nutriology and long-term complications up to May 2017.Measurement data with normal distribution were represented as x±s.Comparison among groups was analyzed using the ANOVA,and pairwise comparisons were done by the Tukey hsd test.Count data were described as the frequency and percentage,and comparisons among groups were analyzed the chi-square test or Fisher exact probability.Ordinal data were analyzed by the Kruskal Wallis test.Results (1) Surgical and postoperative recovery situations:patients in 4 groups underwent successfully LDG.Cases undergoing total LDG and assisted LDG and digestive tract reconstruction time in the B Ⅰ,B Ⅱ,RY and uncut RRY groups were respectively 0,29,13,15 and 45,10,31,21 and (42±7)minutes,(55±8)minutes,(64±8)minutes,(51±6) minutes,with statistically significant differences among 4 groups (x2 =21.628,F=74.441,P＜0.05).(2)Postoperative short-term complications situations:2,2,3 and 1 patients in the B Ⅰ,B Ⅱ,Roux-en-Y and uncut Roux-en-Y groups had respectively postoperative short-term complications,showing no statistically significant difference among 4 groups (x2 =0.840,P＞0.05).(3) Follow-up situations:all patients were followed up,and follow-up time in the B Ⅰ,B Ⅱ,RY and uncut RY groups were respectively (10.8 ± 3.5) months,(10.9 ±3.4)months,(11.3±3.2) months and (11.2±2.2) months,with no statistically significant difference among 4 groups (F=0.200,P＞0.05).① Comparisons of postoperative 1-year nutritional indexes:rates of changes in body mass index (BMI),hemoglobin (Hb),total protein (TP) and albumin were respectively 93％±7％,91％±7％,90％±7％,90％±9％ and 94％±9％,97％±11％,95％±9％,97％±9％ and 101％±9％,99％±7％,98％±7％,99％±7％ and 101％±10％,103％±7％,100％±10％,103％±9％ in the B Ⅰ,B Ⅱ1,RY and uncut RY groups,showing no statistically significant difference among 4 groups (F=1.182,0.724,1.050,0.971,P＞0.05).②)Of 164 patients within 1 year postoperatively,47 were complicated with gastric retention (27,12,6 and 2 with severity in grade 1,2,3 and 4),87 with residual gastritis (53,24,10 and 0 with severity in grade 1,2,3 and 4),and 38 with bile reflux (severity in grade 1).Of 38 patients with bile reflux,33 were combined with residual gastritis,showing a correlation between residual gastritis and bile reflux (r=0.396,P＜0.05).Cases with gastric retention,residual gastritis and bile reflux within 1 year postoperatively were respectively 16,9,21,1and 35,30,13,9 and 16,18,3,1 in the B Ⅰ,B Ⅱ],RY and uncut RY groups,showing statistically significant differences among 4 groups (x2 =21.261,41.103,30.469,P＜ 0.05).There were statistically significant differences in gastric retention occurrence between uncut RY group and B Ⅰ group or B Ⅱ group or RY group (x2 =12.958,6.675,20.065,P＜0.05),and in residual gastritis occurrence between RY group and B Ⅰ group or B Ⅱ group (x2 =20.831,18.587,P＜0.05) and between uncut RY group and B Ⅰ group or B Ⅱ group (x2 =22.452,20.220,P＜0.05).There were statistically significant differences in bile reflux occurrence between RY group and B Ⅰ group or B Ⅱ group (x2 =10.942,16.926,P＜0.05),and between uncut RY group and B Ⅰ group or B Ⅱ group (x2 =12.958,18.620,P＜0.05).Conclusion Roux-en-Y and uncut Roux-en-Y anastomoses are superior to B Ⅰ and B Ⅱ anastomoses in improving residual gastritis and bile reflux in the postoperative digestive tract reconstruction of LDG,and uncut Roux-en-Y anastomosis can effectively reduce occurrence of postoperative gastric retention.
