Abstract:
Objective To evaluate the long-term therapeutic results of intersphincteric resection (ISR) in the treatment of ultra-low rectal cancer.Methods Sixty cases of ultra-low rectal cancer with the inferior border of the tumor within 5 cm to the edge of anus underwent intersphincteric resection (ISR),and the clinical data were analyzed retrospectively.There were 39 males,21 females and their average age was 55 years old (range from 30 to 77 years old).The inferior border of the tumor were from 28 to 50 mm to the edge of anus,averaging 42 mm.Results Sixty patients underwent intersphincteric resection successfully with 3 cases developing anastomotic leakage and 2 cases anastomotic stenosis postoperatively.After a median follow-up period of 49 months (range from 18 to 90 months),local and distant recurrence were observed in 6 and 4 patients respectively.Five-year overall survival rate and disease-free survival rate were 88.3％ and 83.3％ respectively.The mean stool frequency were (3.8 ± 1.3) times in each day based on data from 53 patients,and the stool control function of 73.6％ of all patients was preserved satisfactorily according to Kirwan classification.Conclusions This study indicated that intersphincteric resection might be a candidate technique in the treatment of early stage ultra-low rectal cancer restricted within rectal wall and could achieve satisfactory long-term results in both oncologic and functional respects.
