Background:The present study aimed to evaluate both technical feasibility and safety of intersphincteric resection(ISR) and short-and long-term outcomes after lower rectal tumor.In addition,Group of Patients who underwent laparoscopic ISR were compared with the control group of patients who underwent open ISR.QOL and anal function were evaluated.Study Design:Between July 2008 and December 2016, 1240 patients with primary colorectal tumor underwent surgery,789 patients with colorectal cancer underwent laparoscopic surgery at Gifu University School of Medicine. 57 patients with lower rectal tumor underwent ISR.Patients were classified into an open surgery (OS:n=17) group and a laparoscopy (LAP:n=40) group.Technical feasibility and safety of ISR ,short and long- term outcomes after laparoscopic ISR and open ISR were evaluated. Results: There was no perioperative mortality, the morbidity rate was 28.1% (16/57).The all complication rates were similar in the LAP and OS groups (25.0% vs 35.3%).Postoperative complications detected included bleeding in 1 patient, anastomosis stenosis in 2 patietnt,pyelonephritis in 1 patient ,vaginal fistula in 1 patient ,abcess in 1 patient and ileus in 4 patients of the LAP group. In addition,OS group detected postoperative complications, pyelonephritis in 1 patient, ileus in 4 patient and ,abcess in 4 patient.Cancer recurrence was detected in 4 (7.0%) patient. Conclusions:The present study showed laparoscopic Intersphincteric resection to have a safe postoperative course and to benefit oncologic outcomes. The functional result was objectively good.
