Purpose:To evaluate the influence of prior abdominal surgery on the outcomes after robotic-assisted laparoscopic radical prostatectomy (RALP).Materials and Methods:We retrospectively analyzed patients with prostate cancer who underwent RALP between June 2012 and February 2015 at our institution. Patients with prior abdominal surgery were compared with those without prior surgery while considering the mean total operating, console, and port-insertion times; mean estimated blood loss; positive surgical margin rate; mean duration of catheterization; and rate of complications.Results:A total of 203 patients who underwent RALP during the study period were included in this study. In all, 65 patients (32%) had a prior history of abdominal surgery, whereas 138 patients (68%) had no prior history. The total operating, console, and port-insertion times were 328 and 308 (P=0.06), 252 and 242 (P=0.28), and 22 and 17 minutes (P=0.01), respectively, for patients with prior and no prior surgery. The estimated blood losses, positive surgical margin rates, mean durations of catheterization, and complication rates were 197 and 170 mL (P=0.29), 26.2% and 20.2% (P=0.32), 7.1 and 6.8 days (P=0.74), and 12.3% and 8.7% (P=0.42), respectively. Furthermore, whether prior abdominal surgery was performed above or below the umbilicus or whether single or multiple surgeries were performed did not further affect the perioperative outcomes.Conclusions:Our results suggest that RALP can be performed safely in patients with prior abdominal surgery, without increasing the risk of complications.
Current guidelines recommend a repeat biopsy within 3-6 months after an initial diagnosis of atypical small acinar proliferation (ASAP) due to the high incidence of cancer detection on repeat biopsy. The current study sought to investigate practice patterns after a diagnosis of ASAP in a real-world setting and examine the clinicopathological outcomes of repeat biopsy. The departmental database of the Hyogo Prefectural Nishinomiya Hospital identified 97 of 1,218 patients with a diagnosis of ASAP on initial biopsy from 2011 to 2016. Clinical and pathological data were retrospectively analyzed. Of the 97 patients, 34 (35.1%) underwent a repeat biopsy. Patients with a repeat biopsy had a significantly higher prostate-specific antigen (PSA) velocity and shorter PSA doubling time than patients without a repeat biopsy (P= 0.0002), and of these 34 patients with a repeat biopsy, 16 (47.1%) were diagnosed as having cancer. Multivariate logistic regression analysis revealed that a small prostate (P= 0.0250) and advanced age (P= 0.0297) were associated with cancer detection on repeat biopsy. Of the 16 cancers identified, 13 (81.6%) were diagnosed with a Gleason score >6. The results indicated that the implementation of a repeat biopsy for patients with ASAP could be affected by clinical characteristics in real-world settings, despite the current recommendation of guidelines endorsing immediate repeat biopsy. Prostate volume and age would aid in the decision-making process to perform repeat biopsy in patients with high PSA velocity and short PSA doubling time after a diagnosis of ASAP.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
