RESUMO
INTRODUCTION: While RARP (robotic-assisted radical prostatectomy) has become the predominant surgical approach to treat localized prostate cancer, there is little Canadian data on its oncological and functional outcomes. We describe the largest RARP experience in Canada. METHODS: Data from 722 patients who underwent RARP performed by 7 surgeons (AEH performed 288, TH 69, JBL 23, SB 17, HW 15, QT 7, and KCZ 303 patients) were collected prospectively from October 2006 to December 2013. Preoperative characteristics, as well as postoperative surgical and pathological outcomes, were collected. Functional and oncological outcomes were also assessed up to 72 months postoperative. RESULTS: The median follow-up (Q1-Q3) was 18 months (9-36). The D'Amico risk stratification distribution was 31% low, 58% intermediate and 11% high-risk. The median operative time was 178 minutes (142-205), blood loss was 200 mL (150-300) and the postoperative hospital stay was 1 day (1-23). The transfusion rate was only 1.0%. There were 0.7% major (Clavien III-IV) and 10.1% minor (Clavien I-II) postoperative complications, with no mortality. Pathologically, 445 men (70%) were stage pT2, of which 81 (18%) had a positive surgical margin (PSM). In addition, 189 patients (30%) were stage pT3 and 87 (46%) with PSM. Urinary continence (0-pads/day) returned at 3, 6, and 12 months for 68%, 80%, and 90% of patients, respectively. Overall, the potency rates (successful penetration) for all men at 6, 12, and 24 months were 37%, 52%, and 59%, respectively. Biochemical recurrence was observed in 28 patients (4.9%), and 14 patients (2.4%) were referred for early salvage radiotherapy. In total, 49 patients (8.4%) underwent radio-therapy and/or hormonal therapy. CONCLUSIONS: This study shows similar results compared to other high-volume RARP programs. Being the largest RARP experience in Canada, we report that RARP is safe with acceptable oncologic outcomes in a Canadian setting.
RESUMO
UNLABELLED: Study Type - RCT (randomized trial) Level of Evidence 2b. What's known on the subject? and What does the study add? In a previous randomized controlled trial, barbed polyglyconate suture for vesico-urethral anastomosis was associated with more frequent cystogram leaks, longer mean catheterization times and greater suture costs per case. In the current randomized controlled trial, we show that barbed polyglyconate suture is associated with decreased anastomosis time, decreased need to readjust suture tension, cost reduction, and equal continence and early/late urinary complication rates. OBJECTIVE: To examine the effectiveness of barbed polyglyconate suture (V-Loc 180; Covidien, Mansfield, MA, USA) compared with standard monofilament for posterior reconstruction (PR) and vesico-urethral anastomosis (VUA) during robot-assisted radical prostatectomy (RARP). PATIENTS AND METHODS: A prospective randomized controlled trial was conducted in 70 consecutive RARP cases by a single surgeon (K.C.Z.). Standard VUA was performed using three 4-0 poliglecaprone 25 (Monocryl; Ethicon Endosurgery, Cincinnati, OH, USA) sutures secured with absorbable suture clips (LapraTy, Ethicon; one single 6-inch [15.2 cm] for PR and two attached 6-inch [15.2 cm] for VUA). Barbed suture VUA was performed using two 3-0 6-inch (15.2 cm) barbed polyglyconate sutures. Time to complete the suture set-up by the nursing team, anastomosis time and need to adjust suture tension were recorded. Suture-related complications, validated-questionnaire continence and cost were also examined. RESULTS: Compared with a conventional reconstruction technique, there was a significant reduction in mean nurse set-up time (31 vs. 294 s; P < 0.01) and reconstruction time (13.1 vs. 20.8 min; P < 0.01) for the barbed suture technique. Need to readjust suture tension or to place additional suture clips for watertight closure was greater in the standard monofilament group than in the barbed suture group (6% vs. 24%; P= 0.03). ⢠A cost reduction was recorded at our institution (48.05 vs. 70.25 $CAN) with the barbed suture technique. ⢠With a mean follow-up of 6.2 months, no delayed anastomotic leak or bladder neck contracture was observed in either group. ⢠Pad-free continence outcomes for the monofilament suture vs the barbed suture groups at 1 (64 vs. 69%, P= 0.6), 3 (76 vs. 81%, P= 0.5) and 6 months (88 vs. 92%, P= 0.7) were similar. CONCLUSIONS: ⢠Compared with standard monofilament suture, the unidirectional barbed polyglyconate suture appears to provide safe, efficient and cost-effective PR and VUA during RARP. ⢠Use of the interlocked barbed polyglyconate suture technique prevents slippage, precluding the need for assistance, knot-tying and constant reassessment of anastomosis integrity.

PURPOSE: : Our purpose was to describe the safety and feasibility of a running posterior reconstruction (PR) integrated with continuous vesicourethral anastomosis (VUA) using a novel self-cinching unidirectional barbed suture in robot-assisted radical prostatectomy (RARP). METHODS: : Between March and October 2010, 30 consecutive patients with organ-confined prostate cancer underwent RARP by an experienced single surgeon (KCZ). Upon completion of radical prostatectomy, urinary reconstruction was carried out using 2 knotless, interlocked 6-inches 3-0 V-Loc-180 suture. The left tail of the suture was initially used for PR (starting at 5-o'clock and ran to re-approximate the retrotrigonal layer to the rectourethralis) followed by left-sided VUA (from 6- to 12-o'clock), while the right-sided suture completed the right-sided VUA. Assurance of watertight closure with an intraoperative 300 cc saline visual cystogram was performed in all cases prior to case completion. Perioperative outcomes and 30-day complications were recorded. RESULTS: : All anastamoses were performed without assistance and without knot tying. Median time for nurse setup and urinary reconstruction was 40 seconds (interquartile range [IQR] 25-60) and 14.6 min (IQR 10-18), respectively. The need to readjust suture tension or place Lapra-Ty clips (Ethicon Endo-Surgery, Cincinnati, OH) to establish watertight closure was observed in 2 cases (7%). No patient had clinical urinary leak and there was no urinary retention after catheter removal on mean postoperative day 5 (IQR 4-6). CONCLUSIONS: : Our clinical experience with a novel technique using the interlocked V-Loc suture during RARP for both PR and anastomosis appears to be safe and efficient. Using the barbed suture prevents slippage and eliminates the need for bedside assistance to maintain suture tension or knot tying, thus assuring watertight tissue closure.
RESUMO
BACKGROUND: In Canada, waiting times for referral and surgery exist for both benign and malignant disease. We attempted to evaluate the length of various waiting times for surgery as well as their association with surgical stage in patients with non-small-cell lung cancer (NSCLC). METHODS: This observational study consisted of a retrospective review of data for all patients who underwent an operation with the intent to cure NSCLC between Jan. 1, 1993, and Dec. 31, 2002, at the Montreal General Hospital, McGill University Health Centre, Montréal, Que. Time intervals between multiple preoperative points and surgery were calculated. The patients were then linked via universal health care insurance numbers with data from the centralized provincial inclusive health care database. This allowed the calculation of the precise interval between the patients' first contact with a physician for symptoms related to their malignancy and surgery. Mean time intervals were then compared with surgical stage. RESULTS: We found adequate data for time interval analysis over 10 years for 256 patients who had undergone surgery with intent to cure. The distribution of patients by TNM stage was as follows: stage I, 144 patients (56.3%); stage II, 47 patients (18.4%); stage III, 41 patients (16.0%); and stage IV, 24 patients (9.4%). Mean and median time intervals between initial contact with physician or first onset of symptoms relating to lung cancer and surgery were 208 (standard deviation [SD] 313) days and 109 days, respectively. Mean and median time intervals between initial contact with the thoracic surgeon and surgery were 104 (SD 99) days and 82 days, respectively. No detrimental effect was observed between time to surgery and surgical stage in patients with NSCLC. CONCLUSIONS: Excessive preoperative waiting times before attempts at curative surgical resection for NSCLC exist in our centre. These intervals are exceptionally long, multifactorial and cause for concern.
