RESUMO
This report presents the case of a 63-year-old woman who developed a vesicovaginal fistula as a complication of a previous total hysterectomy. The fistula was treated with the use of the da Vinci X surgical system by a multi-disciplinary operating team, including senior Robotic Urological and Gynecological Surgeons at St. Luke's Hospital in Thessaloniki, Greece. The patient was monitored up to 12 months post-op at the time of writing and she was asked to evaluate post-op quality of life using the SF-36 and ICIQ-SF-UI questionnaires. The robotic surgical procedure was completed successfully. The total operation duration was 105 minutes, without any intra-operative complications. The patient was hospitalized for two days and made a swift, uneventful recovery. Regarding the quality of life, the patient reported satisfactory improvement in almost every domain assessed compared to her pre-op assessment; an improvement that was maintained throughout the reported follow-up period. At the time of writing, the patient reports no long-term complications and satisfactory urinary continence. Robotic-assisted laparoscopic vesicovaginal fistula repair is an effective and safe treatment option for this rare complication, as indicated by both post-operative data and the patient's own self-evaluation in this report. Further research is warranted, focusing on refining the surgical technique and comparing this to other alternative methods aiming to further improve patient outcomes.
RESUMO
OBJECTIVE: To examine the clinical and pathological value of intraoperative frozen section (IFS) in patients undergoing laparoscopic radical prostatectomy (L-RPE) for clinically localized prostate cancer. METHODS: The study includes 198 consecutive cases of L-RPE. After removal of the prostate, a 2-3mm circumferential specimen was obtained from the apical and bladder neck soft-tissue margin and submitted for IFS examination. In cases suspicious for capsular incision (n=57), IFS were taken from the neurovascular bundle/lateral pedicle. RESULTS: The IFS diagnosis from the apical, bladder neck, and neurovascular bundle/lateral pedicle soft-tissue margins was adenocarcinoma in 12 (6%), 1 (0.5%), and 2 (1%) cases, respectively. Patient age, clinical stage, and mean specimen weight were not associated with cancer at the apical IFS. The accuracy, sensitivity, specificity, positive and negative predictive value of the apical IFS to predict cancer in the permanent section of the apical soft-tissue margin was 96%, 70%, 97%, 58%, and 98%, respectively. All the patients (n=15) with cancer at IFS had wide resections of additional tissue in the area of positive soft-tissue margin and all had no cancer in the additional resected tissue. Especially at the apex, IFS decreases the overall PSM status on surgical specimen by 5.1% (apical PSM from 8.6% to 3.5%). CONCLUSION: Because of the low predictive value of IFS of bladder neck and neurovascular bundle/lateral pedicle their use is not recommended. IFS of the apex should be performed to reduce the PSM rate.
