Answer

Future treatment of typical enterovesical fistulae may focus on development and refinement of minimally invasive surgical techniques, such as laparoscopic and robotic, to shorten recovery time and to potentially decrease hospital stay. The benefit and complications of preoperative ureteral stenting for intraoperative identification of the ureter may become a particular area of interest for clinical study. As of the latest review of this article, there are few clinical data to demonstrate the benefit of ureteral stents in preventing ureteral injury.

New modalities in neoadjuvant chemotherapy may allow further bladder preservation strategies. Trends in radiation oncology that permit minimization of collateral organ damage (eg, conformal external beam radiotherapy) and the use of tumor-specific radiosensitizing agents may be highly useful in preventing radiation-induced fistulae.

Improved surgical techniques, including laparoscopic procedures that greatly enhance visualization of the operative field, hold promise for fewer fistula-related complications of gynecologic and urologic procedures.

Advancements in molecular biology and the development of medications to manipulate inflammatory mediators may eventually produce more specifically targeted therapies to decrease the risk of fistula formation in inflammatory conditions, particularly Crohn disease.

Given the low incidence of colovesical fistula, the development of and recruitment for prospective randomized studies is difficult.
