Risk factors for delayed gastric emptying after gastrectomy: a meta analysis / 中华胃肠外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To explore the risk factors of delayed gastric emptying after gastrectomy.</p><p><b>METHODS</b>Meta-analysis was performed to screen risk factors of delayed gastric emptying after gastrectomy based on 19 associated articles published from 2003 to 2013.</p><p><b>RESULTS</b>Gender, operative time, blood loss during operation, surgical settings(emergency, elective surgery), radical surgery were not significantly different between two groups for delayed gastric emptying (all P>0.05). Age more than or equal to 60 years [combined odds ratio(OR)=1.65, 95% confidence interval(CI)1.31-2.09, P<0.01], preoperative gastrointestinal obstruction(combined OR=3.72, 95%CI3.05-4.55, P<0.01), Billroth-II( (combined OR=3.35, 95%CI2.72-4.13, P<0.01), anemia(combined OR=1.48, 95%CI1.08-2.02, P=0.01), intra-abdominal complication (combined OR=2.41, 95%CI1.77-3.29, P<0.01), perioperative blood glucose greater than 8 mmol/L(combined OR=2.64, 95%CI2.00-3.49, P<0.01), postoperative albumin levels lower than 30 g/L (combined OR=2.13, 95%CI1.62-2.79, P<0.01), use of analgesics pump after operation (combined OR=1.74, 95%CI1.33-2.26, P<0.01), having adverse psychological reactions (combined OR=5.94, 95%CI1.79-19.73, P=0.004) were risk factors affecting delayed gastric emptying.</p><p><b>CONCLUSION</b>Age more than or equal to 60, preoperative gastrointestinal obstruction, perioperative blood glucose greater than or equal to 8 mmol/L, postoperative albumin levels less than 30 g/L, Billroth-II(, anemia, intra-abdominal complication, using pain pump after operation, having adverse psychological reactions are risk factors affecting delayed gastric emptying after gastrectomy.</p>
