Background: The aim of this study was to retrospectively investigate the impact of intersphincteric resection (ISR) and Enhanced Recovery After Surgery (ERAS) protocols for rectal cancer., Patients and Methods: Since we implemented rectal ERAS protocol and ISR in 2016, we retrospectively assessed and compared clinical, pathological and survival outcomes of two groups of patients: group 1, treated 2000-2015 (n=242); and group 2, treated 2016-2020 (n=108). Propensity score matching using nearest-neighbor method was used to match each patient of group 1 to a patient of group 2., Results: Before and after matching, the American Society of Anesthesiology score for patients in group 1 was significantly lower than in group 2 (score of 3: 9.9% vs. 25.9%, p<0.0001) as were grade I-II complications (27.7% vs. 45.4% p<0.001). Before and after matching, the quality of the mesorectum excision was significantly lower in group 1 (complete in 31% vs. 59.2% p<0.0001). After matching, 3-year overall survival for groups 1 and 2 were similar (88.2% vs. 92.6%; p=0.988)., Conclusion: ERAS and ISR had no negative impact on the oncological outcome of our patients and increased the preservation of bowel continuity., (Copyright © 2022 International Institute of Anticancer Research (Dr. George J.

Background/aim: Preoperative radiochemotherapy (RCT) followed by total mesorectum excision has become the gold standard for locally advanced carcinoma of the low and middle rectum. The aim of the study is to evaluate the short and long-term outcomes of patients in complete pathological response (PR) following this treatment sequence., Patients and Methods: One hundred and thirty patients were retrospectively included between 2005 and 2017 in an expert centre, with 3 groups formed, according to the PR: i) complete PR (absence of tumour cells on the surgical specimen ypT0N0), ii) partial PR (T or N downsizing) and iii) without PR., Results: The complete PR rate was 13.1%. The complete PR group tended to develop less symptomatic fistulas compared to partial PR and without PR groups (5.8% versus 13.5% versus 18.7, respectively; p=0.607). The 5-year disease-free survival was increased for complete-PR patients (93% versus 79% versus 47%, respectively; p=0.0003) without an improvement in overall survival., Conclusion: Complete PR is associated with an improvement in survival without recurrence and without an improvement in the overall survival at 5 years., (Copyright© 2019, International Institute of Anticancer Research (Dr. George J.
