About

Colovesical fistulas are well-recognized but relatively uncommon pathology to both the general and colorectal surgeon. It is a complication arising from an underlying primary acute to chronic inflammatory process. Although colovesical fistulas are uncommon, they are associated with significant morbidity, affect quality of life, and may lead to death, usually secondary to urosepsis. Early diagnosis and management is essential.

The purpose of the study is to determine the objective use of cystographic evaluation on postoperative day two to guide early Foley catheter removal post colovesical fistula takedown. The hypothesis is that a cystogram showing no extravasation of contrast on postoperative day two will predict safe removal without increased morbidity.

This is an uncontrolled, single arm trial. Patients who meet criteria to undergo either minimally invasive or open colovesical fistula takedown with sigmoid colectomy, without evidence of the need for bladder repair will be eligible to participate. An indwelling Foley catheter is placed intraoperative and continued postoperative. All patients who consent to participate would undergo a cystogram on postoperative day two. The cystogram will be conducted by a radiologist and technician well-trained in the techniques and interpretation of the study. The colorectal surgery enhanced recovery protocol will be followed on all patients with the exception of the cystogram being conducted on post-op day two. If there is no evidence of extravasation of dye is seen on the cystogram the Foley catheter will be removed. Patients will be monitored closely following catheter removal to ensure self-diuresis.

Cystogram on Post-Op Day 2

Description:

An indwelling Foley catheter is placed intraoperative and continued postoperative. All patients who consent to participate would undergo a cystogram on postoperative day two. The cystogram will be conducted by a radiologist and technician well-trained in the techniques and interpretation of the study. The colorectal surgery enhanced recovery protocol will be followed on all patients with the exception of the cystogram being conducted on post-op day two.
