Abstract: Objective To explore the clinical efficacy of modified Trocar peritoneal dialytic catheter implantation versus open peritoneal dialytic catheter implantation.Methods For this single-center retrospective study,a total of 125 patients were reviewed between January 2016 and May 2018.They were divided into two groups according to different surgical approaches(n=64,group A)Modified Trocar peritoneal dialysis catheter implantation and open peritoneal dialysis catheter implantation(n=61,group B)were performed.The clinical data of implanting procedures,postoperative complications and technical survival rate were analyzed.Results As compared with group B,operative duration was shorter(32.5±6.8)min vs.(57.8±14.2)min,length of incision shorter(2.8±0.5)cm vs.(4.1±0.6)cm,volume of intraoperative bleeding less(8.2±0.9)mL vs.(13.9±2.5)mL and intraoperative pain score lower(3.8±0.8 vs.7.2±0.9)in group A(P<0.05).The 1/2/3-year technical survival rate was 91.6%,89.4% and 89.4% in group B versus all 98.1% in group A.And the differences were statistically significant(P<0.05).The incidence of postoperative complications was lower in group A than that in group B,including catheter shifting(6.3% vs.13.1%),leakage(1.6% vs.4.9%)and bleeding(1.6% vs.6.6%).However,there was no significant statistical difference(P>0.05).Conclusions As compared with traditional open peritoneal dialytic catheter implantation,modified Trocar peritoneal dialytic catheter implantation is worth wider popularizing in clinical practices because of shorter operative duration,shorter incision,less intraoperative bleeding,milder intraoperative pain and higher technical survival rate.
