Comparison of the therapeutic effect of laparoscopy with laparotomy preserving anus sphincter surgery in low rectal cancer

Objective: To compare the clinical effects between laparoscopy and laparotomy preserving anus sphincter surgery in low rectal cancer.Methods: Sixty-two patients with low rectal cancer were divided into the control group(27 cases) and observation group(35 cases).The control group and observation group were treated with laparotomy and laparoscopy preserving anus sphincter surgery,respectively.The perioperative situation,incidence of postoperative complications and specimen oncology and anus function after six months of operation between two groups were compared.Results: The operative time,blood loss,exhaust time and hospitalization time in observation group were significantly lower than those in control group(P<0.01).The differences of the postoperative anastomotic fistula,intestinal obstruction,intraperitoneal metastasis,ureteral injury and voiding dysfunction between two groups were not statistically significant(P>0.05).The differences of the average of diameter and length of tumor,distance from the distal edge of the tumor to the distal margin and number of lymph nodes dissected between two groups were not statistically significant(P>0.05).The differences of the incidence rate of totally anal incontinence and 6-month Kirwan standard anus control ability grading between two groups were not statistically significant(P>0.05).Conclusions: Laparoscopy preserving anus sphincter surgery in the treatment the low rectal cancer is small surgical trauma and quick postoperative recovery,the clinical effect of which can achieve the same radical cure of laparotomy preserving anus sphincter surgery.
