Aim of the Work: We investigated oncological, functional outcomes and morbidity after ISR. Methods: This retrospective study included 164 patients who underwent ISR with between 2010 and 2015, Male 56.1%, Female 43.9%, with a median age was 54.5 years, Median follow-up time was of 48 months, Average surgical time was 230 min, Median blood loss was 700 mL and median hospital stay was nine days. Mean tumour size was34 mm. The surgical procedure through a laparotomy (72.6%), laparoscopically (27.4%). Neoadjuvant radiotherapy 89.6% {long-course radiotherapy 74.4%, short-course radiotherapy 15.2%}, neoadjuvant chemotherapy 28.7% and adjuvant chemotherapy 70.1%. Colonic J-pouch 16.5%, Transverse coloplasty 15.9%, a side-to-end anastomosis 26.8% and straight coloanal anastomosis 40.9%. Partial-ISR 36.6%, subtotal-ISR 37.2%, total-ISR 26.2%, diverting ileostomy 6.7%. Results: Operative mortality 1.2%, morbidity 14.6% (anastomotic leakage 3.7%, anastomotic stenosis 1.8%, a recto-vaginal fistula 2.4% bowel obstruction 3%, surgical site infection 3%. Respiratory tract infection 1.2%, local 7.9%, distant recurrence 15.2%, 5-year overall 79.8%, disease-free survival 75.8%, R0 resection 95.1%. Pathologic complete response 11%.

Median bowel motions in a 24-h were 3. Faecal urgency 17.7%. Stool fragmentation 18.9%. Difficult evacuation 17.7%, lifestyle alteration 14.6%. Difficulty Feces/flatus discrimination 43.3%.
