Abstract
PurposeAll reports comparing laparoscopy-assisted anorectoplasty (LAARP) with posterior sagittal anorectoplasty (PSARP) in male high-type imperforate anus include a mix of recto-vesical, recto-prostatic, recto-bulbar, and absent fistula cases without focusing on recto-bulbar fistula (RBF), the most challenging type to treat laparoscopically. We compared LAARP with PSARP for treating only RBF. MethodWe used our fecal continence evaluation questionnaire (FCE; maximum score=10), scoring of magnetic resonance imaging (MRI) findings (MRI scores), and the angle between the rectum and the anal canal (RAA) to assess 20 RBF cases (LAARP=12, PSARP=8) treated from 2000 to 2013 prospectively. ResultsMean ages at surgery, MRI scores, mean RAA, and duration of raised C-reactive protein (6.6 vs. 6.7days; p=NS) were similar. In all cases, postoperative MRI showed no residual fistula and normal urination. LAARP had consistently higher FCE (7.9 vs. 7.8 at 3years; 8.6 vs. 8.3 at 5years; 8.9 vs 8.6 at 7years; p=NS, respectively), less wound infections (0 vs. 37.5%; p<0.05), higher incidence of rectal mucosal prolapse (50.0 vs. 0%; p<0.05), and required less analgesia (p<0.05). ConclusionAlthough LAARP and PSARP are comparable for treating RBF, LAARP is associated with less wound infections and higher incidence of rectal mucosal prolapse.
