Project description:BackgroundThis study aimed to determine whether continuous deep neuromuscular blockade (NMB) improves the surgical conditions and facilitates robotic-assisted laparoscopic radical prostatectomy (RALRP) under low intra-abdominal pressure (IAP) to attenuate the increase in intraocular pressure (IOP) during CO2 pneumoperitoneum in the steep Trendelenburg (ST) position.MethodsSixty-seven patients undergoing RALRP were randomly assigned to a moderate NMB group (Group M), including patients who received atracurium infusion until the end of the ST position, maintaining a train of four count of 1-2; and the deep NMB group (Group D), including patients who received rocuronium infusion, maintaining a post-tetanic count of 1-2. IOP was measured in all patients at nine separate time points. All RALRPs were performed by one surgeon, who rated the overall and worst surgical conditions at the end of the ST position.ResultsThe highest IOP value was observed at T4 (60 min after the ST position) in both Group M (23.3 ± 2.7 mmHg) and Group D (19.8 ± 2.1 mmHg). RALRP was accomplished at an IAP of 8 mmHg in 88% Group D patients and 25% Group M patients. The overall surgical condition grade was 4.0 (3.0-5.0) in Group D and 3.0 (2.0-5.0) in Group M (P < 0.001).ConclusionThe current study demonstrated that continuous deep NMB may improve surgical conditions and facilitate RALRP at a low IAP, resulting in significant attenuation of the increase on IOP. Moreover, low-pressure pneumoperitoneum, facilitated by deep NMB still provided acceptable surgical conditions.Trial registrationClinicalTrials.gov NCT02109133.

Project description:BackgroundThere has been no study of the effect of post end-expiratory pressure (PEEP) on intraocular or intracranial pressure during pneumoperitoneum with steep Trendelenburg positioning. We investigated the effects of 5 cmH2O of PEEP on intraocular pressure and optic nerve sheath diameter as a surrogate for intracranial pressure in robot-assisted laparoscopic radical prostatectomy.MethodsFifty patients scheduled for robot-assisted laparoscopic radical prostatectomy were divided into a zero-PEEP (ZEEP) group and a 5 cmH2O of PEEP (PEEP) group. Intraocular pressure, optic nerve sheath diameter, and respiratory and hemodynamic parameters were measured before induction (T0), 10 minutes after induction of general anesthesia in the supine position before CO2 insufflation (T1), 5 minutes (T2), and 30 minutes (T3) after steep Trendelenburg positioning with pneumoperitoneum, after desufflation of pneumoperitoneum in the supine position (T4), and after 30 minutes in the recovery room postoperatively (T5).ResultsThere was no significant difference in intraocular pressure or optic nerve sheath diameter between the groups during the study. The partial pressure of arterial oxygen and dynamic lung compliance at T1, T2, T3, and T4 were significantly higher in the PEEP than in the ZEEP group. There was no difference in mean arterial pressure or heart rate between groups at any time.ConclusionApplying 5 cmH2O of PEEP did not increase intraocular pressure or optic nerve sheath diameter during pneumoperitoneum with steep Trendelenburg positioning in robot-assisted laparoscopic radical prostatectomy. These results suggest that low PEEP can be safely applied during surgery with pneumoperitoneum and steep Trendelenburg positioning in patients without preexisting eye disease and brain pathology.

Project description:BackgroundTo compare the postoperative continence and clinical outcomes of Retzius-sparing robot-assisted laparoscopic radical prostatectomy (RS-RALP) with non-RS RALP for patients with prostate cancer.MethodsWe searched PUBMED, EMBASE and the Cochrane Central Register from 1999 to 2019 for studies comparing RS-RALP to non-RS RALP for the treatment of prostate cancer. We used RevMan 5.2 to pool the data.ResultsA total of seven studies involving 1620 patients were included in our meta-analysis. No significant difference was found in positive surgical margins (PSM), bilateral nerve-sparing, postoperative hernia, complications, blood loss, or operative time. Postoperative continence was better with RS-RALP compared with non-RS RALP (OR = 1.02, OR: 2.86, 95% CI 1.94-4.20, p < 0.05).ConclusionsRS-RALP had a better recovery of postoperative continence than non-RS RALP. The perioperative outcomes were comparable for the two methods.

Project description:Purpose:The aim of the present study was to evaluate the pathological and oncological outcomes of laparoscopic radical prostatectomy (LRP) and robot-assisted radical prostatectomy (RARP) performed by one surgeon at a single center. Subjects:We evaluated 700 patients with localized prostate cancer (i.e., 250 received LRP and 450 received RARP) in the study. The clinicopathological outcomes, positive surgical margin (PSM) frequency, and biochemical recurrence (BCR)-free survival were compared between LRP and RARP. Results:At diagnosis, the median patient age and level of prostate-specific antigsen in the serum for LRP were 68 years and 8.1 ng/ml, respectively, while those for RARP were 66 years and 7.7 ng/ml, respectively. In the LRP group, the overall PSM rate was 31.2% (11.1% for pT2a, 19.0% for pT2b, 25.0% for pT2c, 60.0% for pT3a, 64.3% for pT3b, and 50% for pT4). In the RARP group, the overall PSM rate was 20.7% (4.8% for pT2a, 15.9% for pT2b, 12.9% for pT2c, 36.9% for pT3a, 46.2% for pT3b, and 100% for pT4). The PSM rate was significantly lower for RARP in men with pT2c, pT3a, or pT3b disease (p = 0.006, p = 0.009, and p = 0.027, respectively). Based on the multivariate analysis, RARP reduced the risk of BCR (hazard ratio = 0.8, p = 0.014). Conclusions:We compared the pathological findings and rates of BCR-free survival between patients who received LRP and those who received RARP at a single center. The rate of BCR-free survival was significantly higher in men classified as D'Amico high-risk patients who received RARP versus that reported in D'Amico high-risk patients who received LRP.

Project description:It remains unclear whether antibiotic prophylaxis (AP) should be recommended or discouraged in robot-assisted laparoscopic radical prostatectomy (RALP) for prostate cancer (PCa). The development of microbial resistance and side effects are risks of antibiotic use. This systematic review (SR) investigates the evidence base for AP in RALP. A systematic literature search was conducted until 12 January 2023, using Embase, MEDLINE, Cochrane CENTRAL, Cochrane CDSR (via Ovid) and CINAHL for studies reporting the effect of AP on postoperative infectious complications in RALP. Of 436 screened publications, 8 studies comprising 6378 RALP procedures met the inclusion criteria. There was no evidence of a difference in the rate and severity of infective complications within 30 days after RALP surgery between different AP protocols. No studies omitted AP. For patients who received AP, the overall occurrence of postoperative infectious complications varied between 0.6% and 6.6%. The reported urinary tract infection (UTI) rates varied from 0.16% (4/2500) to 8.9% (15/169). Wound infections were reported in 0.46% (4/865) to 1.12% (1/89). Sepsis/bacteraemia and hyperpyrexia were registered in 0.1% (1/1084) and 1.6% (5/317), respectively. Infected lymphoceles (iLC) rates were 0.9% (3 of 317) in a RALP cohort that included 88.6% pelvic lymph node dissections (PLND), and 3% (26 of 865) in a RALP cohort where all patients underwent PLND. Our findings underscore that AP is being administered in RALP procedures without scientifically proven evidence. Prospective studies that apply consistent and uniform criteria for measuring infectious complications and antibiotic-related side effects are needed to ensure the comparability of results and guidance on AP in RALP.

Project description:ObjectiveDifferences in outcome after radical prostatectomy for prostate cancer can partly be explained by intersurgeon differences, where degree of experience is one important aspect. This study aims to define the learning curve of robot-assisted laparoscopic prostatectomy (RALP) regarding oncological and functional outcomes.Materials and methodsOut of 4003 enrolled patients in the LAPPRO trial, 3583 met the inclusion criteria, of whom 885 were operated on by an open technique. In total, 2672 patients with clinically localized prostate cancer from seven Swedish centres were operated on by RALP and followed for 8 years (LAPPRO trial). Oncological outcomes were pathology-reported surgical margins and biochemical recurrence at 8 years. Functional outcomes included patient-reported urinary incontinence and erectile dysfunction at 3, 12 and 24 months. Experience was surgeon-reported experience before and during the study. The relationship between surgeon experience and functional outcomes and surgical margin status was analysed by mixed-effects logistic regression. Biochemical recurrence was analysed by Cox regression, with robust standard errors.ResultsThe learning curve for positive surgical margins was relatively flat, with rates of 21% for surgeons who had performed 0-74 cases and 24% for surgeons with > 300 cases. Biochemical recurrence at 4 years was 11% (0-74 cases) and 13% (> 300 cases). Incontinence was stable over the learning curve, but erectile function improved at 2 years, from 38% (0-74 cases) to 53% (> 300 cases).ConclusionsAnalysis of the learning curve for surgeons performing RALP showed that erectile function improved with increasing number of procedures, which was not the case for oncological outcomes.

Project description:PurposeIn addition to incisional hernia, inguinal hernia is a recognized complication to radical retropubic prostatectomy. To compare the risk of developing inguinal and incisional hernias after open radical prostatectomy compared to robot-assisted laparoscopic prostatectomy.MethodPatients planned for prostatectomy were enrolled in the prospective, controlled LAPPRO trial between September 2008 and November 2011 at 14 hospitals in Sweden. Information regarding patient characteristics, operative techniques and occurrence of postoperative inguinal and incisional hernia were retrieved using six clinical record forms and four validated questionnaires.Results3447 patients operated with radical prostatectomy were analyzed. Within 24 months, 262 patients developed an inguinal hernia, 189 (7.3%) after robot-assisted laparoscopic prostatectomy and 73 (8.4%) after open radical prostatectomy. The relative risk of having an inguinal hernia after robot-assisted laparoscopic prostatectomy was 18% lower compared to open radical retropubic prostatectomy, a non-significant difference. Risk factors for developing an inguinal hernia after prostatectomy were increased age, low BMI and previous hernia repair. The incidence of incisional hernia was low regardless of surgical technique. Limitations are the non-randomised setting.ConclusionsWe found no difference in incidence of inguinal hernia after open retropubic and robot-assisted laparoscopic radical prostatectomy. The low incidence of incisional hernia after both procedures did not allow for statistical analysis. Risk factors for developing an inguinal hernia after prostatectomy were increased age and BMI.

Project description:The effects of a recruitment manoeuvre (RM) with positive end-expiratory pressure (PEEP) on lung compliance (CLUNG) are not well characterised in robot-assisted laparoscopic radical prostatectomy (RARP). Patients were allocated to group R (n = 10; with an RM) or C (n = 9; without an RM). An RM involved sustained inflation of 30 cmH2O for 30 s. The lungs were ventilated with volume-controlled ventilation with tidal volume of 7 mL kg-1 of predicted body weight and fraction of inspired oxygen of 0.5. End-tidal carbon dioxide pressure was maintained at normocapnia. Patients were in the horizontal lithotomy position (pre-op). After pneumoperitoneum, patients underwent RARP in a steep Trendelenburg lithotomy position at a PEEP level of 0 cmH2O (RARP0). An RM was used in the R group but not in the C group. Patients were then ventilated with 5 cmH2O PEEP for 1 h after RARP0 (RARP5.1) and 2 h after RARP0 (RARP5.2). Oesophageal pressure and airway pressure were measured for calculating CLUNG and chest wall compliance. CLUNG significantly decreased from pre-op to RARP0 and did not significantly increase from RARP0 to RARP5.1 and RARP5.2 in either group. CLUNG differed significantly between groups at RARP5.1 and RARP5.2 (103 ± 30 vs. 68 ± 11 mL cm-1 H2O and 106 ± 35 vs. 72 ± 9 mL cm-1 H2O; P < 0.05). In patients undergoing RARP, with the addition of RM, the CLUNG was effectively increased from the horizontal lithotomy position to the steep Trendelenburg lithotomy position under pneumoperitoneum.

Project description:This is a two period cross-over study randomizing patients undergoing laparoscopic surgery into 2 different groups: group 1 in which patients receive "deep neuromuscular blockade" in the beginning portion of their laparoscopic surgery followed by a period of "moderate blockade" and, group 2 in which patients receive "moderate neuromuscular blockade" in the beginning portion of their laparoscopic surgery followed by a period of "deep blockade". The deep neuromuscular block is defined as post tetanic count of 1 to 2 and the moderate neuromuscular block is defined as 1-2 twitches. In all patients, sugammadex is used to reverse the block at the end of surgery in order to obtain optimal extubating conditions.
