To compare the clinical effect of two kinds of secondary operation in the treatment of anastomotic leakage after laparoscopic colorectal cancer operation.

The clinical data of 66 patients with anastomotic leakage after laparoscopic colorectal cancer surgery from December 2018 to June 2020 were analyzed retrospectively. According to different surgical procedures, 34 cases were divided into the laparoscopic group, while 32 cases were divided into the laparotomy group. Statistical analysis were performed by using SPSS 23.0 software. The measurement data of operation related indexes, self-care ability and urinary function were expressed as (±s), and were examined by using independent sample t test. The incidence rate of complication was analyzed by using χ² test. A P value of <0.05 was considered as statistically significant difference.

Compared with the laparotomy group, decreased intraoperative blood loss, quicker postoperative exhausting time, and shortened length of hospitalization were observed in the laparoscopic group (P<0.05). There were no significant difference between the two groups in terms of the operation time, the incidence of re-surgical intervention after the operation and closure of stoma、and the total incidence of complications (P>0.05). The scores of the BI scale and the bladder function assessment scale were higher in the laparoscopic group than those in the laparotomy group respectively (P<0.05).

Compared with laparotomy, using laparoscopic surgery to deal with the anastomotic leakage after laparoscopic colorectal cancer could reduce the trauma to the body during the operation, with improved selfcare ability and urinary function after surgery, without increasing the risk of complications.
