Background: Stapled transanal rectal resection is a new alternative for the treatment of outlet obstruction syndrome. The aim of this study was to assess its feasibility and safety in a multicenter context., Materials and Method: The study had a retrospective design and included 102 patients who were operated in 5 centers. All patients complained of symptomatic outlet obstruction. Surgical technique involved a double hemi-circumferential rectal stapling according to the technique described by Longo. Mean follow-up was 17.2 months., Results: The STARR procedure was done in 100 patients (2 patients had a non relaxing sphincter preventing anal dilatation). Immediate postoperative morbidity included bleeding in 4 cases (4%) and rectal stenosis in 3 cases (3%). The main postoperative medium-term complaints were urge to defecate (34%) which was regressive in most patients and de novo incontinence to flatus (9%). Nevertheless, results were considered favorable in 85% of patients., Conclusion: This multicenter study, reporting the results of the largest published series, suggests that the STARR technique is feasible and safe in the medium term for the treatment of rectocele. Occurrence of adverse events such as incontinence to flatus should be better evaluated by future studies with longer follow up in order to assess the actual place of STARR in the treatment of rectocele or outlet obstruction.
