Abstract:
Objective
To investigate the clinical effect of selective application of ultrasonic knife and electric hook in laparoscopic Dixon surgery for rectal cancer.
Methods
A retrospective analysis was performed on 125 patients with rectal cancer who received laparoscopic Dixon surgery from September 2017 to August 2023.The patients were divided into two groups according to the surgical anatomy method: 65 patients in the observation group were selectively treated with ultrasonic knife and electric hook during the operation,and 60 patients in the control group were treated with ultrasonic knife throughout the operation.Operationrelated indicators and postoperative complications were compared between the two groups.SPSS 22.0 was used to process the data.Measurement data were expressed as (x±s) and independent sample t test was performed.The counting data is represented by［ cases (%)］ and tested by line χ2.P＜0.05 was considered statistically significant.
Results
Compared with the control group, there were statistically significant differences in operation time (P＜0.05), but no statistically significant differences in intraoperative blood loss, postoperative 3d abdominal drainage, drainage tube removal time, urinary tube removal time, intestinal function recovery time and postoperative average hospital stay (P＞0.05).No postoperative anastomotic hemorrhage, anastomotic leakage and urinary retention occurred in both groups.The incidence of anastomotic stenosis within 1 year after surgery was 3.1% in the observation group and 3.3% in the control group, with no statistical significance (P＞0.05).
Conclusion
Laparoscopic Dixon surgery for rectal cancer selectively uses ultrasonic knife and electric hook according to the anatomical location and tissue structure characteristics, which is conducive to accelerating the surgical process, reducing the anesthesia time, and reducing the risk of complications.
