Background: The optimal surgical treatment for colonic colorectal carcinoma (CRC) in Lynch Syndrome (LS) and attenuated polyposis coli (A-FAP phenotype) patients is still debated, since there is a high risk of metachronous colonic adenomas and carcinoma after primary surgery. The aim of this study was to compare surgical outcome, functional data, and Quality of Life (QoL) after total colectomy with ileorectal anastomosis (TC-IRA) compared to right (RH) or left hemicolectomy/sigmoidectomy (LH/SI).
Methods: Patients who underwent TC-IRA (ileorectal anastomosis from 8 to 15 cm from the anal verge) for CRC and/or polyposis at our Surgical Department between 2001 and 2017 were included in the study group, and were matched one-to-one by baseline and clinical characteristics with a control group of RH and LH/SI. Morbidity and mortality data were collected (Clavien-Dindo classification). International validated questionnaires were used to investigate QoL and bowel function.
Results: Fifty-five patients were enrolled in each group. No differences were found on length of hospital stay, Clavien-Dindo grade III-IV complications and mortality (p > 0.05). TC-IRA showed a longer operative time than RH and LH/SI (p < 0.0001) and a major blood loss than RH (p < 0.0001). Worse bowel function and worse QoL, only for the bowel-related items, were recorded in TC-IRA group. The general QoL was similar among the groups.
Conclusions: TC-IRA and segmental resection have similar morbidity and mortality. The worse bowel function in TC-IRA group does not impact on the general QoL. These data can be useful in the setting of risk-reducing surgery decision in LS and A-FAP patients.
