Anal sphincteroplasty in the minimally invasive era: Assessment of national trends and complications

Abstract

Fecal incontinence is a debilitating and underreported condition. Despite introduction of novel therapies in recent years, anal sphincteroplasty (AS) remains the surgical choice for certain patients. Previous reports have primarily focused on single-surgeon or single-center experience with AS. The purpose of this study was to assess patient characteristics and perioperative outcomes of AS using a national cohort. Patients (n 5 586) who underwent AS as a primary procedure between 2009 and 2015 were identified by the CPT code as recorded in the study and were evaluated and examined for association with 30-day complications. The number of sphincteroplasties performed decreased seven-fold between 2009 and 2015. Wound infection, wound dehiscence, and urinary tract infection were the most common complications, occurring in 30 (5.1%), 12 (2.1%), and 6 (1%) patients, respectively. Preoperative steroid use and surgeon specialty were associated with wound complications on multivariate analysis. We present the first national study of patients undergoing AS and identify factors that predispose to wound complications. In addition, we demonstrate that the number of anal sphincteroplasties performed in the United States is decreasing dramatically, likely because of novel therapy for fecal incontinence. We hope that this study will assist in patient counseling and call attention to preserving surgical training as utilization of AS rapidly declines.
