Studies were selected based on specific inclusion and exclusion criteria. The primary outcome was delayed gastric emptying(DGE). Secondary outcomes included operation time, intraoperative blood loss, pancreatic fistula, postoperative hemorrhage, intraabdominal abscess, wound infection, time to starting liquid diet, time to starting solid diet, period of nasogastric intubation, reinsertion of nasogastric tube, mortality and hospital stay. The pooled odds ratios(OR) or weighted mean difference(WMD) with 95% confidence intervals(95%CI) were calculated using either a fixed-effects or random-effects model. RESULTS: Eight comparative studies recruiting 650 patients were analyzed, which include two RCTs, one non-randomized prospective and 5 retrospective trial designs. Patients undergoing SSPPD experienced significantly lower rates of DGE(OR = 2.75; 95%CI: 1.75-4.30, P < 0.00001) and a shorter period of nasogastric intubation(OR = 2.68; 95%CI: 0.77-4.58,P < 0.00001), with a tendency towards shorter time to liquid(WMD = 2.97, 95%CI:-0.46-7.83; P = 0.09) and solid diets(WMD = 3.69, 95%CI:-0.46-7.83; P = 0.08) as well as shorter inpatient stay(WMD = 3.92, 95%CI:-0.37-8.22; P = 0.07), although these latter three did not reach statistical significance. PPPD, however, was associated with less intraoperative blood loss than SSPPD [WMD =-217.70, 95%CI:-429.77-(-5.63); P = 0.04]. There were no differences in other parameters between the two approaches, including operative time(WMD =-5.30, 95%CI:-43.44-32.84; P = 0.79), pancreatic fistula(OR = 0.91; 95%CI: 0.56-1.4展开更多
