ABSTRACT
Background: This paper purports to use a meta-analysis to compare the postoperative quality of life (QoL) and nutritional status of between Roux-en-Y (R-Y) and Billroth-I (B-I) reconstruction after distal gastrectomy.Methods: For this study, the following databases were searched for articles published from inception until December 2018: PubMed, Web of Science, EBSCO, and Cochrane library.Results: A total of 13 eligible studies, covering 3645 patients, were selected for a meta-analysis. The analysis showed that compared with B-I group in term of short-term outcomes, patients undergoing R-Y reconstruction did not only have significantly better physiological function (P = 0.02), but had significantly less pain (P = 0.04). In the long-term outcomes, the dyspnea and constipation in the B-I group were worse than that in the R-Y group (P = 0.004; P = 0.04, respectively). Patients in the B-I group had higher cholesterol than those in the R-Y group at 5 years postoperatively (P = 0.003). There were no significant differences in termof other nutritional indicators including total protein, cholesterol, albumin, hemoglobin and weight in short-term outcomes.Conclusions: The final conclusion was that R-Y may be superior to the B-I reconstruction in some aspects of QoL. Besides, R-Y reconstruction could reduce the patient's cholesterol level for a long time. For the short-term outcomes, there were no significant differences in other common nutritional indicators.

BACKGROUND: By comparing the long-term prognostic outcomes after pancreaticoduodenectomy (PD) and limited resection (LR), this study aimed to investigate the optimal surgical modality for duodenal gastrointestinal stromal tumors (GISTs). METHODS: Two authors independently searched PubMed, Web of Science, Embase, and the Cochrane Library for published articles comparing the long-term prognostic and clinicopathological factors of duodenal GIST patients undergoing PD versus LR. Relevant information was extracted and analyzed. RESULTS: After screening, 10 items comprising 623 cases were eventually included. This meta-analysis explicitly indicated that PD treatment was associated with worse long-term prognosis (hazard ratio = 1.93; 95% confidence interval [CI], 1.39-2.69; p < 0.001; I2 = 0) and more complications (odds ratio [OR] = 2.90; 95% CI, 1.90-4.42; p < 0.001; I2 = 10%) than LR treatment. Nevertheless, for duodenal GISTs, PD was related to the following clinicopathological features: invasion of the second part of the duodenum (OR = 3.39; 95% CI, 1.69-6.79; p < 0.001; I2 = 50%), high-degree tumor mitosis (> 5/50 high-power fields; OR = 2.24; 95% CI, 1.42-3.52; p < 0.001; I2 = 0), and high-risk classification (OR = 3.17; 95% CI; 2.13-4.71; p < 0.001; I2 = 0). CONCLUSIONS: Since PD is associated with worse long-term prognosis and more complications, its safety and efficacy should be ascertained. Our findings recommend the use of LR to obtain negative incision margins when conditions permit it.
