Laparoscopic treatment of fourteen cases of pelvic ring disruption: a case series.

PURPOSE: Open surgical approaches for the treatment of anterior pelvic arc lesions are associated with several complications. We present the first retrospective descriptive case series on the use of laparoscopy as an alternative. METHODS: This descriptive, retrospective, single-centre study enrolled all patients who underwent laparoscopy for the treatment of pelvic ring disruption between May 2020 and March 2022. The primary outcome was the procedure failure rate based on conversion to open surgery. Secondary outcomes were the duration of the surgical procedure, x-ray exposure, length of hospitalisation, postoperative pain assessment, and functional scores at the last follow-up. RESULTS: The study included two females and 12 males. The mean age of the study participants was 44.2 (23-67) years. In total, nine (64.3%) patients had pubic symphysis disjunction, four (28.6%) had bilateral fractures of the obturator frames, and one (7%) had both. None of the patients required conversion to open surgery. The median operating times for symphysis pubis disruption, obturator frame fracture, and patients with both injuries were 90.0 (60-120), 135 (105-180), and 240 min, respectively. The median overall operating time was 102.5 (60-240) min. The median Iowa Pelvic Score and Majeed Functional Score at the last follow-up were 87 (70-99) and 84 (70-100), respectively. CONCLUSION: Laparoscopic internal fixation is a reliable treatment for pelvic ring disruption. The clinical and radiological outcomes of our patients suggest the usefulness of this technique as an alternative to open approaches.

Impact of Multiparametric MRI and PSA Density on the Initial Indication or the Maintaining in Active Surveillance During Follow-Up in low-Risk Prostate Cancer.

INTRODUCTION: A greater selection of candidates for active surveillance (AS) of prostate cancer (PCa) may decrease the rate of delayed treatment. We aimed to study: 1) the impact of MRI and PSA density (PSAd) at baseline on the final status, and 2) the impact of bio-clinical features during the follow-up on pursuing AS. MATERIALS AND METHODS: This retrospective, monocentric study between June 2013 and July 2020, included 99 patients in AS (median follow-up: 19 months [18-92]). All MRI were reviewed by a single radiologist. Lost to follow-up were 17 patients and 6 patients chose treatment by themselves. Treatment was proposed in case of upgrading (≥ GG2) or increasing PCa volume. RESULTS: Impact of MRI and PSAd at baseline:  Combining PSAd ≤ 0.15 and PIRADS ≤ 3, the probability to remain in AS was 72%. This rate reached 83% when PSAd ≤ 0.10 was associated to normal MRI.  During follow-up:  One hundred fifty-seven prostatic biopsies (PBx) were performed and 38 (24%) found PCa upgrading. The association between negative MRI and PSAd ≤ 0.10, during follow-up, had an excellent NPV to predict treatment (95%). This combination concerned 25% (37/151) of surveillance biopsies that could have been avoided at the cost of delaying upgrading in 3% (1/37). In multivariate analysis, only PIRADS ≥ 4 before PBx was associated to a risk of treatment during follow-up (OR, 10.4 [95% CI, 4.2-25.8]; P < .0001). CONCLUSION: Using PSAd and MRI at baseline to select patients showed excellent performances to predict the maintenance in AS. During follow-up, MRI PIRADS ≥ 4 was associated to an increased risk of treatment.
