Stapled trans-anal rectal resection (STARR) in the surgical treatment of the obstructed defecation syndrome: results of STARR Italian Registry.

ABSTRACT

PURPOSE: This study was designed to evaluate the safety and efficacy of stapled trans-anal rectal resection (STARR) in the treatment of obstructed defecation syndrome ODS by the analysis of the data collected in the STARR Italian Registry (SIR) with a special emphasis on the analysis of symptoms and quality of life. METHODS: Collected data included, preoperative tests findings, and the evaluation of symptoms; the latter was obtained by using dedicated tools such as the Obstructed Defecation Syndrome Score (ODS-S), the Severity Symptom Score (SSS), and the Continence Grading Scale (CGS). Data on the quality of life were collected by Patient Assessment of Constipation Quality of Life (PAC-QoL) and the Euro Quality of Life-5 Domains Visual Analogue Scale (EQ-5D VAS). The evaluation of the symptoms and the quality of life was repeated 6 and 12 months after surgery. RESULTS: The SIR had collected data on 2171 patients (1653 females, 76.1%; mean age 56.2 years; range 20-96 years). A significant improvement (P < .0001) was seen between preoperative and 12-month follow-up in all scores ODS-S (16.7 vs. 5.0), SSS (15.6 vs. 2.6), CGS (2.0 vs. 0.7), PAC-QoL (51.0 vs. 22.1), and EQ-5D VAS (57.5 vs. 85.7). Complications included defecatory urgency (4.5% at 12 months), bleeding (3.6%), perineal sepsis (3.4%), and one case of rectovaginal fistula (0.05%). CONCLUSION: The analysis of SIR data seems to confirm that STARR is a safe and effective procedure in the treatment of ODS. However, further studies are required to evaluate the long-term stability of results.
