Residual fistula after laparoscopically assisted anorectoplasty: is it a rare problem?

Although satisfactory fecal continence could be achieved by LAARP, we experienced 2 cases with a large residual fistula that required surgical resection. In addition, screening MRI demonstrated the presence of cystic formations in 9 of 18 patients. We recommend that MRI be performed routinely during follow-up of patients treated with LAARP.
