Objective To compare the clinical values of laparoscopic surgery and laparoscopic surgery by pull through technique for anterior of rectum in patients with rectal cancer. Methods From Jan, 2013 to Jan, 2014, 120 patients with low rectal cancer were prospectively collected. The patients were randomly divided into study group (n= 60) and control group (n= 60). Patients in the study group were treated with laparoscopic surgery by pull through technique for anterior resection of rectum, while patients in the control group were treated with laparoscopic surgery. The primary outcomes were intraoperative situations, postoperative complications and recovery. Results When compared with the control group, patients in the study group got a significantly shorter operative duration [(132.32±14.92) vs (154.73±17.65) min, P=0.000];a signiifcantly lower postoperative drainage volume [(299.93±56.49) vs (365.24±68.94) ml, P= 0.000]; a significantly shorter gastrointestinal function recovery time [(57.42±5.84) vs (61.85±7.40) h, P=0.002]; and a signiifcantly less of length of hospital stay [(12.54±2.76) vs (14.75±2.10) d, P= 0.000]. There was no significant difference between the two groups in the amount of bleeding, the number of lymph node dissection, pneumonia, lower extremity arteriovenous thrombosis, incision infection, anastomotic leakage, intestinal obstruction, 2-year recurrence rate and mortality rate (P> 0.05). Conclusion laparoscopic surgery by pull through technique for anterior resection of rectum can accelerate postoperative recovery.

[ ABSTRACT] AIM: To evaluate the guiding effect of high-frequency stimulation ( HFS) on renal denervation ( RDN) , and to compare the similarities and differences of blood pressure changes at the time of electrical stimulation and radiofrequency ablation .METHODS:A total of 6 Kunming dogs were included in this study .Renal artery abnormalities were excluded by angiography .High-frequency stimulation and radiofrequency ablation were performed at the same sites from distal to proximal segments of the renal artery .Invasive blood pressure ( BP) was recorded during the whole proce-dure.The change of the blood pressure was analyzed .HE and Masson staining was adopted to detect the structural changes in the wall of the renal artery and surrounding tissues .The immumohistochemical staining for tyrosine hydroxylase ( TH) was used to observe the renal nerve damage after ablation .RESULTS: Electrical stimulation and radiofrequency ablation were delivered in a total of 50 sites.The BP increasing response was induced at 34%sites (n=17), while the rest sites (66%, n=33) had no response.Compared with the baseline , HFS caused the increases in systolic BP of (0.34 ±3.38), (0.41 ±3.04), (10.47 ±5.73), (13.27 ±3.63), (10.17 ±1.87) and (0.78 ±1.87) mmHg in 6 serial 20 s time segments during 120 s of HFS at positive BP response sites .Similarly, the increases in systolic BP by (-0.88 ±3.44) , (-1.64 ±3.47), (13.17 ±3.12), (12.82 ±3.21), (9.50 ±2.68) and ( -6.09 ±2.21) mmHg were observed dur-ing 120 s of ablation procedure at the same sites in 6 serial 20 s time segments .At non-responding sites , HFS and ablation failed to cause a significant increase in systolic BP .The mean area of nerves in the response sites was ( 0.51 ±0.28 ) mm2, whereas that in non-response sites was (0.09 ±0.06) mm2(P<0.01).The average absorbance values of TH in re-nal nerves at ablation and non-ablation sites were 0.031 ±0.015 and 0.085 ±0.018 ( P <0.01 ) , respectively . CONCLUSION:Renal sympathetic nerves can be effectively mapped by HFS .Radiofrequency ablation guided by HFS is valid to injure sympathetic nerves around renal artery .
