Proctoscopy following transrectal prostate biopsy can control rectal bleeding after prostate biopsy.

Abstract

Rectal bleeding is a common complication of transrectal ultrasound-guided prostate biopsy (TRPB). Massive rectal bleeding after TRPB can be life threatening. We initiated proctoscopy after TRPB to clarify the incidence of rectal bleeding and evaluated the usefulness of proctoscopy for controlling bleeding after TRPB. Two hundred and fifty six patients who underwent TRPB were included in the study. TRPB was performed under local anesthesia. Post-biopsy, we performed a proctoscopy to evaluate the degree of rectal bleeding at four levels (G0, no bleeding; G1, traces; G2, venous bleeding requiring hemostasis; and G3, massive venous bleeding or arterial bleeding). Once the bleeding site on the rectal wall was identified, a gauze tampon was placed at the bleeding site and compressed for a few minutes. A second proctoscopy was performed to confirm complete hemostasis, after which the TRPB was terminated. Proctoscopy revealed that the degree of bleeding was G0 in 27 cases, G1 in 104 cases, G2 in 116 cases, and G3 in nine cases. Rectal bleeding that required hemostasis (G2 and G3) was observed in 125 of 256 cases (48.3%). Among the 125 cases, bleeding was stopped by compression in 121 cases; in the remaining four cases, bleeding continued despite compression and was stopped by suturing of the bleeding site. Suturing was performed by urologists, and none of the 256 patients had problematic posterior hemorrhage. Proctoscopy enables precise and effective pressure hemostasis. Moreover, suturing hemostasis under direct vision can be performed in cases in which pressure hemostasis is difficult. Continued proctoscopy allays urologists' fear of post-TRPB rectal bleeding.
