Abstract:
Objective To comparative analyze the anorectal function before and after anus-preserving laparoscopic rectal resection in ultra low rectal cancer.Methods Radical excision of ultra low rectal cancer was performed with ultrasonic scalpel on 43 patients based on the concept of TME and ultra low colorectal/ anal anastomosis was perfomed by applying the manual anastomosis with two operations out of anus.The time of guid being controlled in the rectus,rectual rest pressure (RRP),anal rest pressure (ARP) and anal maximal contraction pressure (AMCP) were tested before operation.The function of their rectus and anus was tested,including the number of bowel movement in one day of 1,3,6 months after operation,the time of guid being controlled in the rectus,RRP,ARP and AMCP after 3,6 months of operation et al.Results All the operations were finished successfully,four cases were converted to open surgery,but there was no serious damage.All cases were followed up for 6 to 36 months with average of 20 months.After 3 months of operation,the retention time of liquid in rectus,the defecate feel function,the anus control function,RRP and ARP was statistically significant (P ＜ 0.05) compared to them before operation,there was no statistical significance (including AMCP) (P ＞ 0.05) after 6 months of operation.The results of tests in annus and rectus were near normal level after 6 month of operation.Conclusion The manual anastomosis with two operations out of anus in the laparoscopic anal sphincter preserving resection of ultra low rectal cancer is safe,economical,effective,minimally invasive and shorter hospital stay,it is worth to be widely used.
