The effect of ultrasound-guided compression immediately after transrectal ultrasound-guided prostate biopsy on postbiopsy bleeding: a randomized controlled pilot study

The effect of heated lidocaine gel on pain reduction during transrectal ultrasound-guided prostate biopsy: a randomized-controlled study

PURPOSE

To determine whether intrarectal local anesthesia (IRLA) with heated lidocaine gel provides pain reduction during transrectal ultrasound (TRUS)-guided prostate biopsy.

METHODS

We conducted a randomized-controlled study with 153 participants who underwent TRUS-guided, systematic 12-core prostate biopsy from May 2018 to June 2019. These participants were divided into three test groups. Before prostate biopsy, group A (51 patients) received no local anesthesia, group B (51 patients) received IRLA with 20 mL 2% lidocaine gel stored at room temperature, and group C (51 patients) received IRLA with heated (40 ℃) 20 mL 2% lidocaine gel. Pain was assessed using the 0-10 visual analogue scale (VAS) at three time points: VAS-1: during probe insertion, VAS-2: during biopsy, VAS-3: 30 min after the procedure. Complications during and after the procedure were evaluated.

RESULTS

The mean VAS-2 score was significantly lower in group C compared to groups A and B (A, 4.6; B, 4.2; and C, 3.2; p < 0.05). There was no significant difference among the three groups in mean VAS-1 and VAS-3 scores. No significant difference was detected in incidence of complications between the three groups. No allergic reactions to lidocaine gel were observed.

CONCLUSION

IRLA with heated lidocaine gel provides more effective pain control during TRUS-guided prostate biopsy than does conventional IRLA and no local anesthesia, without an increase of complications.

Endoscopic Therapy in the Management of Patients With Severe Rectal Bleeding Following Transrectal Ultrasound-Guided Prostate Biopsy: A Case-Based Systematic Review

Rectal bleeding is a known complication of transrectal ultrasound-guided prostate biopsy. It is usually mild and resolves spontaneously. However, massive life-threatening hemorrhage can also rarely occur in this setting, potentially presenting a therapeutic conundrum. We hereby delineate the case of a patient who experienced severe intermittent lower gastrointestinal bleeding following a transrectal ultrasound-guided prostate biopsy. Traditional tamponade methods failed to control the hemorrhage. Subsequently, an urgent flexible sigmoidoscopy revealed an anterior rectal wall prominence with biopsy punctures as the possible source of bleeding. Endoclip was successfully applied at the bleeding site, achieving permanent hemostasis. The patient had an uneventful recovery and was discharged from the hospital. While the use of endoclipping has been widely reported in gastrointestinal endoscopy, its application remains exceedingly rare in this group of patients. To our knowledge, this case represents only the third report of endoclipping alone to treat massive rectal bleeding follwing a prostate biopsy procedure. In addition, we systematically review published medical literature to evaluate endoscopic techniques aimed at managing this important complication. This article illustrates that endoscopic therapy may present an efficient, noninvasive method to deal with severe post-biopsy rectal hemorrhage. Therefore, prompt consultation with the gastroenterology service should be advocated.

Hemostatic effect and psychological impact of an oxidized regenerated cellulose patch after transrectal ultrasound-guided prostate biopsy: A prospective and retrospective study

To investigate the usefulness of the oxidized regenerated cellulose patch (ORCP) for postbiopsy hemostasis, anxiety, and depression in patients undergoing transrectal ultrasound-guided prostate biopsy.This was a prospective-retrospective study of 300 patients who underwent systematic 12-core prostate biopsy from August 2016 through March 2018. The ORCP was inserted into the rectum immediately after prostate biopsy in the prospective group (n = 150), while the retrospective group (n = 150) underwent prostate biopsy alone. The frequency rate and duration of hematuria, rectal bleeding, and hematospermia were compared between the 2 groups. Anxiety and depression were assessed with the hospital anxiety and depression scale before and after prostate biopsy in the prospective group.The frequency rates of hematuria and hematospermia showed no significant differences between the prospective versus retrospective groups (64.7% vs 66.7%, P = .881; 18 vs 20%, P = .718; respectively). Frequency of rectal bleeding was significantly lower in the prospective group than in the retrospective group (26.7% vs 42.7%, P = .018). However, there were no significant differences in median duration of rectal bleeding, hematuria, or hematospermia between the 2 groups (2, 5, and 2 days vs 2, 7, and 1 day, P > .05, respectively, for the prospective vs retrospective group). Multivariate analysis found that ORCP insertion was a significant protective factor against postbiopsy rectal bleeding (P = .038, odds ratio 0.52). Only anxiety level in the prospective group before versus after prostate biopsy was significantly reduced (5 vs 4, P = .011).ORCP insertion after prostate biopsy is an effective and simple method for decreasing rectal bleeding. ORCP insertion may also alleviate anxiety in patients undergoing prostate biopsy.

The management of rectal bleeding following transrectal prostate biopsy: A review of the current literature

INTRODUCTION

Since the advent of prostate-specific antigen (PSA)-based testing, transrectal ultrasound (TRUS)-guided prostate biopsy has become a standard part of the diagnostic pathway for prostate cancer (PCa). Rectal bleeding is one of the common side effects of this transrectal route. While rectal bleeding is usually mild and self-limiting, it can be life-threatening. In this article, we examine rectal bleeding post-TRUS-guided prostate biopsy and explore the literature to evaluate techniques and strategies aimed at preventing and managing this common and important complication.

METHODS

A PubMed literature search was carried out using the keywords "transrectal-prostate-biopsy-bleed." A search of the bibliography of reviewed studies was also conducted. Additionally, papers in non-PubMed-listed journals of which the authors were aware were appraised.

RESULTS

Numerous modifiable risk factors for this bleeding complication exist, particularly anticoagulants/antiplatelets and the number of core biopsies taken. Successfully described corrective measures for such rectal bleeding include tamponade (digital/packs/catheter/tampon/condom), endoscopic sclerotherapy/banding/clipping, radiological embolization, and surgical intervention.

CONCLUSIONS

We advocate early consultation with the colorectal/gastroenterology and interventional radiology services and a progressive, stepwise approach to the management of post-biopsy rectal bleeding, starting with resuscitation and conservative tamponade measures, moving to endoscopic hemostasis ± radiological embolization ± transanal surgical methods. Given the infrequent but serious nature of major rectal bleeding after TRUS biopsy, we recommend the establishment of centralized databases or registries forthwith to prospectively capture such data. To the best of our knowledge, this is the first comprehensive look specifically at the management of post-TRUS biopsy rectal bleeding.
