Abstract:
Objective: It is not yet to be clarified whether proximal gastrectomy with double tract anastomosis reconstruction (PG-DT) for gastric cancer increases postoperative complications. This meta-analysis aims to evaluate the safety and efficacy of PG-DT for upper gastric cancer. Methods: The Chinese and English literatures about PG-DT and total gastrectomy with Roun-en-Y digestive tract reconstruction (TG-RY) for upper gastric cancer were searched from PubMed, Embase, Cochrane Library, Wiley Online Library, Web of Science, CNKI net, Wanfang database and VIP database. Literature inclusion criteria: (1) prospective or retrospective cohort study of PG-DT and TG-RY for upper gastric cancer published publicly; (2) patients with upper gastric cancer; (3) the enrolled literatures included at least one of the following outcome indicators: operation time, intraoperative blood loss, postoperative exhaust time, postoperative feeding time, hospitalization time, number of harvested lymph nodes, postoperative complications, postoperative 1-year albumin, postoperative 1-year hemoglobin and 1-, 3-, 5-year survival after surgery. Literature exclusion criteria: (1) reviews, case reports, conference summaries and other non-control studies; (2) studies published repeatedly, studies with incomplete or unextractable information. The search time ended in February 2021. The basic information and evaluation indicators included in the article were extracted. The retrospective study was evaluated using Newcastle-Ottawa literature quality evaluation scale. The prospective randomized controlled study was evaluated using Jadad modified scale. Meta-analysis was performed using Review Manager 5.3. Publication bias was assessed using funnel map. Publication bias was tested using Egger tools. Results: A total of 385 literatures were searched, finally 2 randomized controlled trials and 16 retrospective cohort study were included. There were 1521 patients, including 692 in the PG-DT group and 829 in the TG-RY group. The meta-analysis of the enrolled indicators showed that as compared to TG-RYT group, PG-DT group had less intraoperative blood loss (OR=-54.58, 95%CI: -57.77 to -51.38, P<0.001), shorter postoperative exhaust time (OR=-0.21, 95%CI: -0.29 to -0.13, P<0.001), shorter hospitalization time (OR=-0.98, 95%CI: -1.31 to -0.64, P<0.001), less harvested lymph nodes (OR=-6.07, 95%CI: -7.14 to -4.99, P<0.001), lower morbidity of postoperative complication (OR=0.32, 95%CI: 0.24 to 0.43,P<0.001), higher level of postoperative 1-year albumin (OR=1.90, 95%CI: 1.08 to 2.77, P<0.001) and postoperative 1 year hemoglobin (OR=5.07, 95%CI: 2.83 to 7.31, P<0.001). While there were no significant differences in operation time (OR=0.08, 95%CI: -4.24 to 4.39, P=0.97), postoperative feeding time (OR=-0.05, 95%CI: -0.15 to 0.06, P=0.39), 1-year survival after surgery (OR=1.61, 95%CI: 0.69 to 3.75, P=0.27), 3-year survival after surgery (OR=1.31, 95%CI: 0.81 to 2.10, P=0.27) and 5-year survival after surgery (OR=1.50, 95%CI: 0.86 to 2.63, P=0.15) between two groups. Conclusions: PG-DT treatment for upper gastric cancer is safe and feasible. Compared with TG-RY, PG-DT has advantages in intraoperative bleeding, postoperative exhaust time, hospitalization time, morbidity of postoperative complication and postoperative nutritional indicators.
