Study Of Short-term Effects Of 3D And 2D Laparoscopic Radical Resection Of Rectal Cancer

Objective: To compare the short-term effects of 3D and 2D laparoscopy in radical resection of rectal cancer.Methods: One hundred and forty-eight rectal patients who suffered from rectal cancer and went on laparoscopic radical resection of rectal carcinoma in Dalian Medical University Second Affiliated Hospital of Gastrointestinal surgery in one specific treatment group from Jan.2014 to Aug.2017 were included in the study.All cases were diagnosed as rectal cancer by pathological examination and all the postoperative pathology was adenocarcinoma.They were divided into two groups.The 86 patients operated with the 3D system were compared with 62 patients operated with the 2D system by perioperative data.The procedure followed the principle of total mesorectal excision and no tumor and was strictly followed by the lymph node dissection of the radical resection of rectal cancer.The general information and operation related indexes were compared between 3D laparoscopic group and 2D laparoscopic group.General information includes gender composition,age and body mass index.The operation data includes the operation time,the intraoperative blood loss and number of harvested lymph node.The postoperative data includes postoperative passage of flatus,time for dieting,indwelling catheter time,days of hospital stay and postoperative complications.Postoperative pathological data includes the diameter of tumor,the distance between tumor and the distal part of intestinal canal and TNM staging.Statistical analysis of data used SPSS18.0 statistical software.The difference of measurement data was compared with mean ± standard deviation((x|-) ±S).The difference of count data was compared with chi-square test.The rank sum test of the independent sample is used to compare the measurement data of the abnormal distribution.Test level are selected α=0.05.Results: There were no significant differences in age,sex,body mass index,the total operation time,pathological type,TNM staging,the diameter of tumor,the distance between tumor and the distal part of intestinal canal,indwelling catheter time,days of hospital stay and postoperative complications(P > 0.05).All the patients completed laparoscopic radical operation successfully without conversion to open surgery.Compared with 2D group,the intraoperative blood loss was less [(74.42±36.87)ml vs.(102.76±67.31)ml,P<0.05];the number of harvested lymph node was more [(14.69±7.45)vs.(9.10±4.69),P<0.05];the postoperative passage of flatus was earlier [(2.22±1.16)days vs.(2.84±1.22)days,P<0.05];the time for dieting[(2.56±1.94)days vs.(4.14±1.48)days,P<0.05] was earlier in 3D group.Conclusion: Compared with 2D laparoscopic radical resection of rectal cancer,that 3D laparoscopic radical resection of rectal cancer is safe and feasible,more importantly,3D laparoscopic surgery is more efficient in short-term effects.3D laparoscopic surgery for rectal cancer,compared with 2D laparoscopic technology has significant advantages,which can decrease the intraoperative blood loss,speed the recovery of postoperative gastrointestinal function,eat earlier,and dissect lymph node more thorough.
