Defining minimal invasive surgical therapy for benign prostatic obstruction surgery: Perspectives from a global knowledge, attitude, and practice survey

Objective:To scrutinize the definitions of minimal invasive surgical therapy(MIST)and to investigate urologists’knowledge,attitudes,and practices for benign prostatic obstruction surgeries.Methods:A 36-item survey was developed with a Delphi method.Questions on definitions of MIST and attitudes and practices of benign prostatic obstruction surgeries were included.Urologists were invited globally to complete the online survey.Consensus was achieved when more than or equal to 70%responses were“agree or strongly agree”and less than or equal to 15%responses were“disagree or strongly disagree”(consensus agree),or when more than or equal to 70%responses were“disagree or strongly disagree”and less than or equal to 15%responses were“agree or strongly agree”(consensus disagree).Results:The top three qualities for defining MIST were minimal blood loss(n=466,80.3%),fast post-operative recovery(n=431,74.3%),and short hospital stay(n=425,73.3%).The top three surgeries that were regarded as MIST were Urolift®(n=361,62.2%),Rezum®(n=351,60.5%),and endoscopic enucleation of the prostate(EEP)(n=332,57.2%).Consensus in the knowledge section was achieved for the superiority of Urolift®,Rezum®,and iTIND®over transurethral resection of the prostate with regard to blood loss,recovery,day surgery feasibility,and post-operative continence.Consensus in the attitudes section was achieved for the superiority of Urolift®,Rezum®,and iTIND®over transurethral resection of the prostate with regard to blood loss,recovery,and day surgery feasibility.Consensus on both sections was achieved for EEP as the option with the better symptoms and flow improvement,lower retreatment rate,and better suitable for prostate more than 80 mL.Conclusion:Minimal blood loss,fast post-operative recovery,and short hospital stay were the most important qualities for defining MIST.Urolift®,Rezum®,and EEP were regarded as MIST by most urologists.

Estimation of Physiologic Ability and Surgical Stress scoring system for predicting complications following abdominal surgery: A metaanalysis spanning 2004 to 2022

BACKGROUND Postoperative complications remain a paramount concern for surgeons and healthcare practitioners.AIM To present a comprehensive analysis of the Estimation of Physiologic Ability and Surgical Stress(E-PASS)scoring system’s efficacy in predicting postoperative complications following abdominal surgery.METHODS A systematic search of published studies was conducted,yielding 17 studies with pertinent data.Parameters such as preoperative risk score(PRS),surgical stress score(SSS),comprehensive risk score(CRS),postoperative complications,post-operative mortality,and other clinical data were collected for meta-analysis.Forest plots were employed for continuous and binary variables,withχ2 tests assessing heterogeneity(P value).RESULTS Patients experiencing complications after abdominal surgery exhibited significantly higher E-PASS scores compared to those without complications[mean difference and 95%confidence interval(CI)of PRS:0.10(0.05-0.15);SSS:0.04(0.001-0.08);CRS:0.19(0.07-0.31)].Following the exclusion of low-quality studies,results remained valid with no discernible heterogeneity.Subgroup analysis indicated that variations in sample size and age may contribute to hetero-geneity in CRS analysis.Binary variable meta-analysis demonstrated a correlation between high CRS and increased postoperative complication rates[odds ratio(OR)(95%CI):3.01(1.83-4.95)],with a significant association observed between high CRS and postoperative mortality[OR(95%CI):15.49(3.75-64.01)].CONCLUSION In summary,postoperative complications in abdominal surgery,as assessed by the E-PASS scoring system,are consistently linked to elevated PRS,SSS,and CRS scores.High CRS scores emerge as risk factors for heightened morbidity and mortality.This study establishes the accuracy of the E-PASS scoring system in predicting postoperative morbidity and mortality in abdominal surgery,underscoring its potential for widespread adoption in effective risk assessment.

Assessment of the effectiveness of weight-adjusted antibiotic administration,for reduced duration,in surgical prophylaxis of primary hip and knee arthroplasty

BACKGROUND Prophylactic antibiotics have significantly led to a reduction in the risk of postoperative surgical site infections(SSI)in orthopaedic surgery.The aim of using antibiotics for this purpose is to achieve serum and tissue drug levels that exceed,for the duration of the operation,the minimum inhibitory concentration of the likely organisms that are encountered.Prophylactic antibiotics reduce the rate of SSIs in lower limb arthroplasty from between 4%and 8%to between 1%and 3%.Controversy,however,still surrounds the optimal frequency and dosing of antibiotic administration.AIM To evaluate the impact of introduction of a weight-adjusted antibiotic prophylaxis regime,combined with a reduction in the duration of administration of post-operative antibiotics on SSI incidence during the 2 years following primary elective total hip and knee arthroplasty METHODS Following ethical approval,patients undergoing primary total hip arthroplasty(THA)/total knee arthroplasty(TKA)with the old regime(OR)of a preoperative dose[cefazolin 2 g intravenously(IV)],and two subsequent doses(2 h and 8 h),were compared to those after a change to a new regime(NR)of a weight-adjusted preoperative dose(cefazolin 2 g IV for patients<120 kg;cefazolin 3g IV for patients>120 kg)and a post-operative dose at 2 h.The primary outcome in both groups was SSI rates during the 2 years post-operatively.RESULTS A total of n=1273 operations(THA n=534,TKA n=739)were performed in n=1264 patients.There was no statistically significant difference in the rate of deep(OR 0.74%(5/675)vs NR 0.50%(3/598);fishers exact test P=0.72),nor superficial SSIs(OR 2.07%(14/675)vs NR 1.50%(9/598);chi-squared test P=0.44)at 2 years postoperatively.With propensity score weighting and an interrupted time series analysis,there was also no difference in SSI rates between both groups[RR 0.88(95%CI 0.61 to 1.30)P=0.46].CONCLUSION A weight-adjusted regime,with a reduction in number of post-operative doses had no adverse impact on SSI incidence in this population.

Results of Open Surgical Treatment of Humeral Paddle Fractures about 63 Cases

Fractures of the humeral paddle, common to young adults, are most often complex, linked to violence and an increase in road accidents. The objective of our work is to evaluate our functional results, in the medium term, correlated with a review of the literature. This is a retrospective study of 63 patients, carried out in the traumatology-orthopedics department 1 of the IBN EL JAZZAR hospital in KAIROUAN, over a period of 7 years from January 2015 to December 2021. The average age of patients was 39 years (17 - 68 years). Predominantly male. The etiologies are dominated by falls and accidents on public roads. Fractures are classified according to the Müller and Allgöwer classification where type C is found in 51% of cases. All our patients undergo an olecranon osteotomy in 71% of cases. Osteosynthesis using a Lecestre plate combined with screwing or plugging is used in 84% of cases. The evolution is marked by complications observed in eight patients (16%), including two cases of sepsis, four cases of elbow stiffness (8%), one case of joint callus and one case of pseudarthrosis. Our results are evaluated according to the Mayo Elbow Performance Score, they are excellent and good in 71% of cases, average in 18% of cases and poor in 11% of cases. Fractures of the humeral paddle are fractures with a satisfactory functional prognosis, requiring ad integrum anatomical restoration and solid osteosynthesis allowing early rehabilitation of the elbow. One case of joint callus and one case of pseudarthrosis.

Comparison of Surgical Techniques Used in Treating Acromioclavicular Dislocation in Patients Participating in Sports: A Systematic Review

Introduction: The acromioclavicular joint is a superficial diarthrodial joint that surrounds the medial articular facet of the acromion and the distal portion of the clavicle. Due to its anatomy and biomechanics, it is highly susceptible to trauma and in young men who play contact sports, acromioclavicular dislocation is common. This article aimed to systematically review the literature and compare the surgical techniques used in the treatment of acromioclavicular dislocation in patients who practice sports. Methods: This systematic review was conducted according to the International Preferred Reporting Items for Systematic Review and Meta-Analyses guidelines. Eligible studies for this systematic review included articles in English or Spanish published between 2013 and 2023, which mention the occurrence of acromioclavicular dislocation during sports practices. Additionally, only studies that addressed the surgical treatment of acromion-clavicular dislocation and contained original data on the topic were included. Results: We found 144 eligible studies after searching the LILACS and PubMed databases. Based on the inclusion and exclusion criteria and the reviewers’ consensus, we selected four studies for the systematic review. 133 patients with AC joint displacement were evaluated. Mean Age: approximately 31.90 years. 81.92 of these injuries occurred during sports practice. Surgical Procedures Used: titanium plates fixation (49 patients), arthroscopy (24), single tunnel technique (30) and coracoid sling technique (30). The results of the visual analog scale and Constant-Murley scores varied between the techniques used. Twenty-two complications after surgical treatment were identified. Conclusion: A significant variability of operative techniques can be used in the surgical approach of acromioclavicular dislocation, such as arthroscopy, single tunnel, coracoid sling and titanium plates. Although it presented excellent functional results compared to the other three techniques evaluated by this review, using titanium plates is not the gold standard since other techniques not assessed by this work may be more effective.

Usefulness of the Surgical Apgar Score to Predict the Occurrence of Major Complications in the Early Post-Operative Period of Major Surgeries: Experience of Two Second-Category Hospitals in Cameroon

Objective: The Surgical Apgar Score (SAS) is a tool for intraoperative stratification of the risk of serious complications in the early postoperative period. It varies from 0 to 10 points divided into three risk categories (0 to 4 high, 5 to 7 moderate, 8 to 10 low). The aim of the study was to evaluate its relevance in predicting the appearance of these complications. Material and methods: This descriptive and analytical study was carried out at the “Laquintinie” Hospital in Douala and at the Central Hospital in Yaounde, Cameroon. The main data were collected on a population of patients over 18 years old and recorded on a survey form. They consisted of variables of main interest and exposure variables. Univariate and multivariate statistical analysis using top-down logistic regression models made it possible to evaluate the association of each variable of main interest and each exposure variable. The association was significant at P Results: Of the 88 patients studied, the SAS was 3 hours. In multivariate, this link persisted only and strongly for the SAS OR (IC) 0.1 (0.1 - 0.2) and p = 000. Conclusion: The study found a specific and powerful link between the SAS score < 4 and the occurrence of complications in the early postoperative period, in favor of its relevance in predicting them.

Review of Two Years of Surgical Activities of the General Surgery Department of the Reference Health Center of Commune I of Bamako Mali

The objectives of this work were to evaluate the surgical activities carried out in the general surgery department of the Reference Health Center of Commune I of Bamako, to describe the sociodemographic characteristics of the operated patients, to determine the main pathologies encountered and to evaluate qualitatively the result of the treatment. In order to improve performance, and the quality of care, and to identify common pathologies in the surgical department, we undertook a retrospective study on surgical activities from January 2009 to December 2010. At the end of this study, out of 474 men and 187 women (equal sex ratio 2.53);we were able to determine the frequency of surgical pathologies. Farmers, housewives and pupils/students were the most represented with 25.9% respectively;20% and 13.3%. The most frequently observed pathologies were wall hernia (44.8%), prostate adenoma (12%) and acute appendicitis (10.5%). The average length of hospitalization was 3.43 days. Infectious complications affected 25 patients (3.8% of cases) and a death rate of 0.45% (i.e. 3 patients). The average cost of care was 53,500 FCFA. Indeed, the reality of surgical practice in health centers was not the same because of the level of skills of practicing surgeons.

Surgical Treatment of Osteonecrosis of the Femoral Head Using Minimally Invasive Surgical Drilling and Cancellous Grafting at Brazzaville University Hospital

Introduction: Osteonecrosis of the femoral head (ONTF) is a debilitating condition. Several treatments have been proposed with controversial results. The aim of our study was to evaluate treatment by surgical drilling coupled with in situ cancellous grafting. Materials and methods: Our study was a case-control study conducted at Brazzaville University Hospital from 1st January 2018 to 31 December 2023. It compared two groups of patients with ONTF: non-operated (13 patients, 20 hips) and operated (22 patients, 35 hips). We used the visual digital scale (VDS) for pain assessment, the Merle D’Aubigne-Postel (MDP) scoring system for clinical and functional assessment, and the evolution of necrosis. Results: The group of non-operated patients had a mean age of 35.69 ± 3.4 years, no improvement in pain with an EVN above seven at the last recoil and a mean global MDP score falling from 12.7 before offloading to 10.13 at one year. The group of patients operated on had a mean age of 37.86 ± 7.02 years, a significant reduction in pain (p = 0.00004) and a significantly increased MDP score (p = 0.0034). A comparison of the two groups of patients showed significant stabilization of the necrotic lesions in the operated patients (p = 0.00067), with better satisfaction in the same group. Conclusion: Surgical drilling combined with grafting in the treatment of early-stage ONTF has improved progress in our series. The technique is reproducible and less invasive. It has made it possible to delay unfavorable progression and, consequently, hip replacement surgery.

Role of ablation therapy in conjunction with surgical resection for neuroendocrine tumors involving the liver

BACKGROUND Resection of hepatic metastasis from neuroendocrine tumors(NETs)improves quality of life and prolongs 5-year survival.Ablation can be utilized with surgery to achieve complete resection.Although several studies report long-term out-comes for patients undergoing ablation,none have explored perioperative effects of ablation in patients with metastatic NETs.AIM To determine if intra-operative ablation during hepatectomy increases risk of ad-verse outcomes such as surgical site infections(SSIs),bleeding,and bile leak.METHODS A retrospective analysis of the hepatectomy National Surgical Quality Impro-vement Program database from 2015-2019 was performed to determine the odds of SSIs,bile leaks,or bleeding in patients undergoing intraoperative ablation when compared to hepatectomy alone.RESULTS Of the 966 patients included in the study,298(30.9%)underwent ablation during hepatectomy.There were 78(11.7%)patients with SSIs in the hepatectomy alone group and 39(13.1%)patients with a SSIs in the hepatectomy with ablation group.Bile leak occurred in 41(6.2%)and 14(4.8%)patients in the two groups,respec-tively;bleeding occurred in 117(17.5%)and 33(11.1%),respectively.After con-trolling for confounding variables,ablation did not increase risk of SSI(P=0.63),bile leak(P=0.34)or bleeding(P=0.07)when compared to patients undergoing resection alone on multivariate analysis.CONCLUSION Intraoperative ablation with hepatic resection for NETs is safe in the perioperative period without significant increased risk of infection,bleeding,or bile leak.Surgeons should utilize this modality when appropriate to a-chieve optimal disease control and outcomes.

Incidence of surgical site infection in minimally invasive colorectal surgery

BACKGROUND Surgical site infection(SSI)is a common complication of colorectal surgery.Minimally invasive surgery notably reduces the incidence of SSI.This study aimed to compare the incidences of SSI after robot-assisted colorectal surgery(RACS)vs that after laparoscopic assisted colorectal surgery(LACS)and to analyze associated risk factors for SSI in minimally invasive colorectal surgery.AIM To compare the incidences of SSI after RACS and LACS,and to analyze the risk factors associated with SSI after minimally invasive colorectal surgery.METHODS Clinical data derived from patients who underwent minimally invasive colorectal surgery between October 2020 and October 2022 at the First Affiliated Hospital of Soochow University were collated.Differences in clinical characteristics and surgeryrelated information associated with RACS and LACS were compared,and possible risk factors for SSI were identified.RESULTS A total of 246 patients(112 LACS and 134 RACS)were included in the study.Fortythree(17.5%)developed SSI.The proportions of patients who developed SSI were similar in the two groups(17.9%vs 17.2%,P=0.887).Diabetes mellitus,intraoperative blood loss≥100 mL,and incision length were independent risk factors for SSI.Possible additional risk factors included neoadjuvant therapy,lesion site,and operation time.CONCLUSION There was no difference in SSI incidence in the RACS and LACS groups.Diabetes mellitus,intraoperative blood loss≥100 mL,and incision length were independent risk factors for postoperative SSI.

Effect of weight-adjusted antimicrobial antibiotic prophylaxis on postoperative dosage and surgical site infection incidence in total joint arthroplasty

Surgical site infections(SSI)following total joint arthroplasty pose a significant concern for both providers and patients across the globe.Currently,administration of antimicrobial antibiotic prophylaxis is used throughout the world to reduce the incidence of SSI.However,the correct dosage and frequency of administration remains debatable.In this editorial,we emphasized the determination of the effect of administration of weight-adjusted antimicrobial antibiotic prophylaxis regime on the incidence of SSI and postoperative dosage reduction compared to the conventionally used regime during total joint arthroplasty.The results demonstrated similar efficacy between both regimes with respect to the incidence of SSI.In addition,weight-adjustment led to reduced postoperative dosage and has the potential to reduce chances of achieving lower therapeutic concentration,drug resistance,drug toxicity,and costs.

Urethroplasty among Elderly Men, Surgical Techniques and Outcomes

Introduction: Urethroplasty remains the gold standard for the management of urethral stricture. However, the treatment of stricture disease in the elderly tends to be less invasive due to the presumption that they might not be able to stand long hours of surgery and might have higher rates of recurrence due to poor wound healing from microangiopathy. We present our experience with the outcomes of urethroplasty among elderly men seen at the Komfo Anokye Teaching Hospital from January 2012 to December 2021. Methods: This was a retrospective review of data captured in the urology database on all patients 65 years and above who underwent urethroplasty at the hospital over the study period. Data was obtained on patients’ demographics, stricture characteristics, urethroplasty technique, and outcome. A successful outcome was defined as peak flow rate > 15 mls/s, a patent urethra on retrograde urethrogram, patient satisfaction with urine stream, or restoration of the normal stream of urine with only one attempt at urethral calibration or internal urethrotomy postoperatively. Data was analyzed using PASW Statistics for Windows, Version 18.0. Results: Overall, 43 urethroplasties were done over the study period in elderly men. The age range was 65 to 87 years. The commonest aetiology was catheterization (62.79%) followed by urethritis (32.56%). Stricture length ranged from 0.5 cm to 16 cm with a mean of 3.93 cm. Most patients (60.46%) had bulbar urethral strictures. The repair methods employed were anastomotic urethroplasty (62.80%), fasciocutaneous flap (FCF) ventral onlay (13.95%), buccal mucosa graft (BMG) ventral onlay urethroplasty (4.65%), and staged urethroplasty (4.65%). Three of the patients (6.98%) had a combination of anastomotic and tissue transfer urethroplasty. The overall success rate was 88.37%. Complications included three surgical site infections, two urethral diverticula and one glans dehiscence. Conclusion: Elderly men tolerate urethroplasty well and the procedure should not be denied solely based on age.

Operating Room Nurses’ Role in Multidisciplinary Surgical Coordination for a Patient with a Large Abdominal Tumor and Multiple Pelvic Fractures

In this study,we have summarized the coordination of operating room nurses participating in the multidisciplinary team in diagnosing and treating a patient with a large abdominal tumor and multiple pelvic fractures.To perform surgical treatment on patients with various conditions,it is crucial to consider the patients from a holistic perspective.Thus,the existing medical model has shifted from a“disease-centered”approach focusing on single-disciplinary diagnosis and treatment,to a“patient-centered”approach that involves multiple disciplines in diagnosis and therapy.Operating room nurses,as crucial collaborators of surgeons,should make necessary adjustments to enhance their comprehension of patients,improving the overall quality of surgical coordination.

Analysis of the Clinical Value of Surgical Treatment and Postoperative Anti-Infection Treatment of Acute Suppurative Appendicitis

Objective: To explore the clinical value of surgical treatment and postoperative anti-infection treatment for acute suppurative appendicitis. Methods: A total of 116 patients with acute suppurative appendicitis were enrolled in this study. The collection period was from December 2021 to December 2023. The patients were randomly grouped into a control group (surgical treatment) and an observation group (surgical treatment and postoperative anti-infection treatment), of 58 patients each. At the end of the treatment, the results of each index of the two groups were compared. Results: The length of hospitalization time, exhaust time, and incidence of complications in the observation group were shorter than those of the control group (P < 0.05). The total effective rate of the observation group was higher than that of the control group (P < 0.05). Conclusion: It is crucial to perform anti-infective treatment promptly after surgical treatment in patients with acute suppurative appendicitis. It can effectively prevent the occurrence of complications and improve the clinical efficacy. Hence, it is worthy of research and promotion.

Assessing the Impact of General Anesthesia and Bronchial Intubation in Conjunction with Thoracic Paravertebral Nerve Block on Cellular Immunity and Surgical Management in Tuberculous Pyothorax Patients

Objective:This study aims to investigate the impact of combining general anesthesia with bronchial intubation and thoracic paravertebral nerve block during surgery for patients with tuberculous pyothorax.Methods:Eighty patients diagnosed with tuberculous pyothorax,admitted to the hospital between January 2023 and September 2023,were randomly selected for this study.The patients were divided into control and study groups using a numerical table method.The control group underwent general anesthesia with bronchial intubation,while the study group received general anesthesia with bronchial intubation in conjunction with thoracic paravertebral nerve block.Subsequently,the patients were monitored to assess mean arterial pressure,heart rate variations,and adverse reactions to anesthesia.Results:The study group exhibited significantly lower mean arterial pressure and heart rate levels during the post-surgical incision,immediate end of surgery,and immediate extubation periods compared to the control group(P<0.05).Furthermore,the Ricker and Ramsay scores in the study group were significantly lower than those in the control group(P<0.05).Conclusion:The combined use of general anesthesia via bronchial intubation and thoracic paravertebral nerve block has been found to stabilize mean arterial pressure and heart rate while providing effective sedation for surgical treatment in patients with tuberculous septic thorax.

Role of preoperative magnetic resonance imaging on the surgical outcomes of radical prostatectomy:Does preoperative tumor recognition reduce the positive surgical margin in a specific location?Experience from a Thailand prostate cancer specialized center

Objective Multiparametric magnetic resonance imaging(MRI)has become the standard of care for the diagnosis of prostate cancer patients.This study aimed to evaluate the influence of preoperative MRI on the positive surgical margin(PSM)rates.Methods We retrospectively reviewed 1070 prostate cancer patients treated with radical prostatectomy(RP)at Siriraj Hospital between January 2013 and September 2019.PSM rates were compared between those with and without preoperative MRI.PSM locations were analyzed.Results In total,322(30.1%)patients underwent MRI before RP.PSM most frequently occurred at the apex(33.2%),followed by posterior(13.5%),bladder neck(12.7%),anterior(10.7%),posterolateral(9.9%),and lateral(2.3%)positions.In preoperative MRI,PSM was significantly lowered at the posterior surface(9.0%vs.15.4%,p=0.01)and in the subgroup of urologists with less than 100 RP experiences(32%vs.51%,odds ratio=0.51,p<0.05).Blood loss was also significantly decreased when a preoperative image was obtained(200 mL vs.250 mL,p=0.02).Multivariate analysis revealed that only preoperative MRI status was associated with overall PSM and PSM at the prostatic apex.Neither the surgical approach,the neurovascular bundle sparing technique,nor the perioperative blood loss was associated with PSM.Conclusion MRI is associated with less overall PSM,PSM at apex,and blood loss during RP.Additionally,preoperative MRI has shown promise in lowering the PSM rate among urologists who are in the early stages of performing RP.

Neglected and Relapsed Clubfoot in Adults, the Functional Outcome of Acute Surgical Correction

Background: Neglected clubfoot in this series is defined as untreated equino-cavo-adducto-varus in older children or adults. Relapsed clubfoot is the residual deformity that remains after single or multiple surgical interventions. Severely neglected clubfoot rarely exists today in developed countries, except in some emigrants from low- and middle-income countries. Acute surgical management with corrective mid-foot osteotomy and elongation of the Achilles tendon has an excellent functional outcome. Objective: To assess the functional outcome of acute correction of neglected Talipes-quinoa-varus deformity in adults. Methods: This is a cross-sectional, hospital–based multi-centric study. Forty patients were included in this study. Midfoot osteotomy and elongation of the Achilles tendon were performed on all patients. Data was collected using a questionnaire and the functional outcome has been assessed using the American Orthopedic Foot and Ankle Society Score (AOFAS). This score was measured before surgery and one year after surgery. Results: the mean age was 19.9 ± 4.7 years. Males were 25 (62.5%) and females were 15 (37.5%). The mean preoperative AOFAS score was 37.7 ± 7.1 (poor). This score improved to 80.7 ± 13.7 (good to excellent), two years after surgery. However, this indicates a significant change in the functional outcome after the operation (p value Conclusion: acute correction of neglected and relapsed TEV with elongation of the Achilles tendon and single midfoot osteotomy has excellent functional outcome as assessed by AOFAS Score. The satisfaction with this procedure is impressive. The younger age population showed better outcomes with this procedure.

Clinical outcomes for men with positive surgical margins after radical prostatectomy—results from the South Australian Prostate Cancer Clinical Outcomes Collaborative community-based registry

Objective Positive surgical margins(PSMs)after radical prostatectomy(RP)indicate failure of surgery to completely clear cancer.PSMs confer an increased risk of biochemical recurrence(BCR),but how more robust outcomes are affected is unclear.This study investigated factors associated with PSMs following RP and determined their impact on clinical outcomes(BCR,second treatment[radiotherapy and/or androgen deprivation therapy],and prostate cancer-specific mortality[PCSM]).Methods The study cohort included men diagnosed with prostate cancer(pT2-3b/N0/M0)between January 1998 and June 2016 who underwent RP from the South Australian Prostate Cancer Clinical Outcomes Collaborative database.Factors associated with risk of PSMs were identified using Poisson regression.The impact of PSMs on clinical outcomes(BCR,second treatment,and PCSM)was assessed using competing risk regression.Results Of the 2827 eligible participants,28%had PSMs—10%apical,6%bladder neck,17%posterolateral,and 5%at multiple locations.Median follow-up was 9.6 years with 81 deaths from prostate cancer recorded.Likelihood of PSM increased with higher pathological grade and pathological tumor stage,and greater tumour volume,but decreased with increasing surgeon volume(odds ratio[OR]:0.93;95%confidence interval[CI]:0.88-0.98,per 100 previous prostatectomies).PSMs were associated with increased risk of BCR(adjusted sub-distribution hazard ratio[sHR]2.5;95%CI 2.1-3.1)and second treatment(sHR 2.9;95%CI 2.4-3.5).Risk of BCR was increased similarly for each PSM location,but was higher for multiple margin sites.We found no association between PSMs and PCSM.Conclusion Our findings support previous research suggesting that PSMs are not independently associated with PCSM despite strong association with BCR.Reducing PSM rates remains an important objective,given the higher likelihood of secondary treatment with associated comorbidities.

The application of internal suspension technique in retroperitoneal robot-assisted laparoscopic partial nephrectomy with a new robotic system KangDuo Surgical Robot-01:Initial experience

Objective To assess the feasibility of internal suspension technique in retroperitoneal robot-assisted laparoscopic partial nephrectomy(rRAPN)with a new robotic platform called KangDuo Surgical Robot-01(KD-SR-01)system(Suzhou KangDuo Robot Co.,Ltd.,Suzhou,China)and discuss its surgical technique.Methods A 44-year-old male patient was admitted with a 2.5 cm tumor on dorsolateral upper pole of the left kidney.The R.E.N.A.L.nephrometry score of this patient was 4x.This patient underwent rRAPN with KD-SR-01.The perinephric fat between the tumor and Gerota's fascia was preserved,which was used for internal suspension traction during tumor resection.Postoperative follow-up data were collected.Results The surgery was successfully carried out with a duration of 127 min,in which the docking time was 6 min 25 s and console time was 60 min.The warm ischemia time was 19 min 53 s,and the estimated blood loss was 0 mL.The pathological histology showed a pathological tumor stage 1a clear cell renal cell carcinoma,with a negative surgical margin.The World Health Organization/International Society of Urological Pathology(WHO/ISUP)grade of this patient was Grade 2.No recurrence was observed during the 6-month follow-up.Conclusion Internal suspension in rRAPN is feasible and effective with use of the new robotic system KD-SR-01.
