Abstract:Objective To explore the effect of laparoscopic combined with total intersphincteric resection (ISR) in treatment of ultra-low rectal cancer.Methods Clinical data of 118 patients with ultra-low rectal cancer from April 2014 to July 2016 were retrospectively, and divided into study group (n = 59) and control group (n = 59) according to different surgical methods. The study group was treated with laparoscopic combined with total ISR, and the control group was treated with open total ISR. The patients were followed up for 3 years to analyze and summarize the effect and advantages of laparoscopic combined with total ISR in the treatment of ultra-low rectal cancer.Results The study group had less bleeding during operation, and the postoperative exhaust time and hospitalization time were shorter (P < 0.05). There were 7 patients (11.86%) with complications in the study group, and the proportion of patients with good anal function was 96.61%, there were significantly different with control group (P < 0.05). There was no significant difference in long-term effect (local recurrence rate, distant metastasis rate and mortality) between the two groups (P > 0.05).Conclusion Laparoscopic total ISR for ultra-low rectal cancer has the advantages of less complications, less intraoperative blood loss, fast postoperative recovery and good long-term effect, which is worthy of clinical application.
