Meta-Analysis
BACKGROUND
Increased survival of patients undergoing total gastrectomy for gastric cancer has prompted several efforts to improve long-term postgastrectomy syndrome (PGS) outcomes. Whether a J-pouch (JP) reconstruction may be more beneficial than a standard Roux-en-Y (RY) is controversial.
METHODS
A systematic review with meta-analysis was conducted, including studies reporting long-term outcomes of patients treated with total gastrectomy and JP vs RY esophagojejunostomy for gastric adenocarcinoma. A literature search was performed on PubMed, Scopus, and Google Scholar. Primary endpoints were symptom control, weight loss, eating capacity (EC), and quality of life (QoL) with at least 6 months of follow-up. Safety endpoints were explored.
RESULTS
Overall, 892 patients were included from 15 studies (6 randomized controlled trials [RCTs] and 9 non-RCTs): 452 (50.7%) in the JP group and 440 (49.3%) in the RY group. Compared with RY, JP showed a significantly lower rate of dumping syndrome (13.8% vs 26.9%, odds ratio [OR], 0.29; 95% confidence interval [CI], 0.14-0.58; P < .001; I = 22%) and heartburn symptoms (20.4% vs 39.0%; OR, 0.29; 95% CI, 0.14-0.64; P = .002; I = 0%). Reflux (OR, 0.61; 95% CI, 0.28-1.32; P = .21; I = 42%) and epigastric fullness (OR, 0.60; 95% CI, 0.18-2.05; P = .41; I = 69%) were similar in both groups. Weight loss and EC were similar between the groups. QoL outcome seemed to be burdened by bias. There was no difference in morbidity, mortality, and anastomotic leak rate between groups. Operative time was significantly longer for JP than for RY (271.9 vs 251.6 minutes, respectively; mean difference, 21.55; 95% CI, 4.64-38.47; P = .01; I = 96%).
CONCLUSION
JP reconstruction after total gastrectomy for gastric cancer is as safe as RY and may provide an advantage in postgastrectomy dumping syndrome and heartburn symptoms.
