Aim Transanal transabdominal proctosigmoidectomy (TATA) with a coloanal anastomosis is an alternative to abdominoperineal excision of the rectum (APR) for low rectal cancer. Neorectal prolapse is an unusual complication following TATA. This study aimed to determine the incidence of neorectal prolapse after TATA for low rectal cancer. Method This cohort study was conducted in a tertiary referral colorectal centre. From a prospectively maintained database including 1093 patients treated for rectal cancer between 1984 and 2016 we identified those who underwent sphincter‐preserving surgery. Data regarding the incidence, management and outcomes of neorectal prolapse were analysed. Results A total of 409 patients were identified, of whom 185 underwent open surgery and 224 a minimally invasive surgical procedure (MIS). All received neoadjuvant chemoradiation. Neorectal prolapse occurred in 4.6% ( n = 19) with an incidence of 2.2% in the open and 6.7% in the MIS group ( P = 0.023), with no difference between MIS techniques. There was one recurrence of neorectal prolapse (5.9%). The incidence of neorectal prolapse was higher in women (9.5%) than men (2.5%) ( P = 0.011). There were no differences in local recurrence rates between the neorectal prolapse group (5.3%) and our population without prolapse (3.4%) ( P = 0.79). Conclusion Neorectal prolapse is a rare occurrence following minimally invasive sphincter‐saving surgical procedures performed for rectal cancer. It appears to be more frequent in patients who undergo MIS procedures and in women.
