High Failure Rate Following Restorative Surgery for Rectal Prolapse in Systemic Sclerosis Patients

Systemic sclerosis (SSc) is a rare autoimmune connective tissue disorder. Colonic disorders are reported in 70% of patients. Only a few cases of rectal prolapse surgical repair in SSc patients were published, demonstrating high recurrence rate following any restorative surgery. The aim of this study is to present our surgical experience combined with the reported cases of SSc patients who underwent surgical interventions for rectal prolapse.

We reviewed our data and the published reports in the English literature of patients with SSc who underwent surgery for rectal prolapse. We located 6 case reports, in addition to 3 patients who were operated in our center.

A total of 19 procedures (9 patients) were included, among them 17 restorative surgeries and 2 low anterior resections (LAR) with end-colostomy. All patients were female (mean age 70.3). Index surgery was perineal rectosigmoidectomy in 5, abdominal resection rectopexy in 3, and LAR with colostomy in 1 patient. All patients following restorative surgery suffered from fecal incontinence. 5 patients (62.5%) who underwent restorative surgery required at least 1 re-operation. The 2 patients who underwent LAR and colostomy reported a complete resolution of anorectal symptoms with a major improvement in their quality of life.

High recurrence rate is expected in SSc patients with rectal prolapse who undergo a restorative procedure. Low anterior resection and permanent colostomy provide an alternative surgical option to patients with SSc and prolapse in contrast to restorative surgery. We believe that this surgical approach should be offered for these patients.
