Abstract:
Objective To evaluate the risk factors of gallstone occurrence after gastrectomy for gastric cancer.Methods Relevant documents published from 1990 to 2014 were retrieved through Pubmed,Cochrane Library,Embase,Web of Science CNKI,Wan Fang and VIP databases search.The Meta-analysis was applied with RevMan 5.3 software for Odds ratio and 95％ CI.Results 24 studies were selected for this Meta-analysis which included 3 randomized controlled trials,13 cohort studies and 8 case-controlled studies.These 24 studies included patient number which ranged from 32 to 893.The pooled OR (95％ CI) and P values of OR (95 ％ CI) for physiologic digestive tract reconstruction were 0.53 (0.44 ～ 0.65,P ＜ 0.05) ;amount of resection of stomach,1.98 (1.29 ～ 3.04,P ＜ 0.05) ; lymphadenectomy,0.38 (0.21 ～ 0.72,P ＜ 0.05) ; vagotomy,0.24 (0.13 ～ 0.45,P ＜ 0.05) ; and pylorus preservation,0.70 (0.48 ～ 1.02,P ＞ 0.05).Conclusions Physiologic digestive tract reconstruction and vagus nerve preservation reduced occurrence of gallstones after gastrectomy.On the other hand,total gastrectomy and extensive lymph node dissection increased the occurrence.There was no significant difference in the occurrence of gallstones whether there was pylorus preservation or not.
