Rehabilitation versus surgical reconstruction for non-acute anterior cruciate ligament injury (ACL SNNAP): a pragmatic randomised controlled trial

BackgroundAnterior cruciate ligament (ACL) rupture is a common debilitating injury that can cause instability of the knee. We aimed to investigate the best management strategy between reconstructive surgery and non-surgical treatment for patients with a non-acute ACL injury and persistent symptoms of instability.MethodsWe did a pragmatic, multicentre, superiority, randomised controlled trial in 29 secondary care National Health Service orthopaedic units in the UK. Patients with symptomatic knee problems (instability) consistent with an ACL injury were eligible. We excluded patients with meniscal pathology with characteristics that indicate immediate surgery. Patients were randomly assigned (1:1) by computer to either surgery (reconstruction) or rehabilitation (physiotherapy but with subsequent reconstruction permitted if instability persisted after treatment), stratified by site and baseline Knee Injury and Osteoarthritis Outcome Score—4 domain version (KOOS4). This management design represented normal practice. The primary outcome was KOOS4 at 18 months after randomisation. The principal analyses were intention-to-treat based, with KOOS4 results analysed using linear regression. This trial is registered with ISRCTN, ISRCTN10110685, and ClinicalTrials.gov, NCT02980367.FindingsBetween Feb 1, 2017, and April 12, 2020, we recruited 316 patients. 156 (49%) participants were randomly assigned to the surgical reconstruction group and 160 (51%) to the rehabilitation group. Mean KOOS4 at 18 months was 73·0 (SD 18·3) in the surgical group and 64·6 (21·6) in the rehabilitation group. The adjusted mean difference was 7·9 (95% CI 2·5–13·2; p=0·0053) in favour of surgical management. 65 (41%) of 160 patients allocated to rehabilitation underwent subsequent surgery according to protocol within 18 months. 43 (28%) of 156 patients allocated to surgery did not receive their allocated treatment. We found no differences between groups in the proportion of intervention-related complications.InterpretationSurgical reconstruction as a management strategy for patients with non-acute ACL injury with persistent symptoms of instability was clinically superior and more cost-effective in comparison with rehabilitation management

The IDENTIFY study: the investigation and detection of urological neoplasia in patients referred with suspected urinary tract cancer - a multicentre observational study

Objective To evaluate the contemporary prevalence of urinary tract cancer (bladder cancer, upper tract urothelial cancer [UTUC] and renal cancer) in patients referred to secondary care with haematuria, adjusted for established patient risk markers and geographical variation. Patients and Methods This was an international multicentre prospective observational study. We included patients aged ≥16 years, referred to secondary care with suspected urinary tract cancer. Patients with a known or previous urological malignancy were excluded. We estimated the prevalence of bladder cancer, UTUC, renal cancer and prostate cancer; stratified by age, type of haematuria, sex, and smoking. We used a multivariable mixed-effects logistic regression to adjust cancer prevalence for age, type of haematuria, sex, smoking, hospitals, and countries. Results Of the 11 059 patients assessed for eligibility, 10 896 were included from 110 hospitals across 26 countries. The overall adjusted cancer prevalence (n = 2257) was 28.2% (95% confidence interval [CI] 22.3–34.1), bladder cancer (n = 1951) 24.7% (95% CI 19.1–30.2), UTUC (n = 128) 1.14% (95% CI 0.77–1.52), renal cancer (n = 107) 1.05% (95% CI 0.80–1.29), and prostate cancer (n = 124) 1.75% (95% CI 1.32–2.18). The odds ratios for patient risk markers in the model for all cancers were: age 1.04 (95% CI 1.03–1.05; P < 0.001), visible haematuria 3.47 (95% CI 2.90–4.15; P < 0.001), male sex 1.30 (95% CI 1.14–1.50; P < 0.001), and smoking 2.70 (95% CI 2.30–3.18; P < 0.001). Conclusions A better understanding of cancer prevalence across an international population is required to inform clinical guidelines. We are the first to report urinary tract cancer prevalence across an international population in patients referred to secondary care, adjusted for patient risk markers and geographical variation. Bladder cancer was the most prevalent disease. Visible haematuria was the strongest predictor for urinary tract cancer

The use of 68Ga-PET/CT PSMA in the staging of primary and suspected recurrent renal cell carcinoma

Purpose: The role of Ga-PSMA PET/CT in the staging of prostate cancer is well known. PSMA is also overexpressed in the neovasculature of other tumours including renal cell carcinoma (RCC), suggesting there may be a role for the use of Ga-PSMA PET/CT. Thus far, there has been limited literature documenting the use of Ga-PSMA PET/CT in the investigation and management decisions of RCC. Methods: This was a retrospective case series of patients who received a Ga-PSMA PET/CT scan for staging or restaging of RCC between July 2016 and December 2018. Primary outcome measure was to identify whether Ga-PSMA PET/CT changed management compared to standard diagnostic CT imaging. Analysis was based on four categories: (1) identification of new disease, (2) refuting disease on CT imaging, (3) identification of synchronous primaries, and (4) concordance with CT imaging. Results: 38 Ga-PSMA PET/CT scans met inclusion criteria. Primary staging scans were performed in 16 patients, of which 75% showed avid primary lesions, with the majority of clear cell subtype. Management was changed in 43.8% of patients. CT agreed with Ga-PSMA PET/CT in 37.5% of cases. Restaging scans were performed in 22 patients. 40.9% of patients had management changed by results of Ga- PSMA PET/CT. CT agreed with Ga- PSMA PET/CT in 36.4% of cases. Management was predominantly changed due to the identification of new sites of suspected metastases, as well as the detection of synchronous primaries. Conclusions: Ga-PSMA PET/CT directly changed management in 42.1% of cases. Strongest detection rates occurred in those patients with clear cell RCC. The results of this study suggest there may be merit in the use of the modality in the staging of RCC. Further analysis, both with respect to histological confirmation, efficacy and cost-benefit, is required to determine whether there is a role for routine Ga-PSMA PET/CT imaging

Borderline mucinous testicular tumour: diagnostic and management difficulties

A 45-year-old man presented with right-sided testicular swelling and pain. An examination found a tender, firm right testis, a clinically normal left testis and no palpable lymphadenopathy. Tumour and inflammatory markers were within normal limits. A scrotal ultrasound scan showed an intratesticular, avascular lesion measuring 4.4×2.6×1.8 cm. A CT scan of his chest/abdomen/pelvis (CT C/A/P) showed no metastatic or primary lesions. An elective right-inguinal orchidectomy was subsequently performed. Histopathology showed a cystic mucinous tumour lined with intestinal-type epithelium. Differentials of metastatic adenocarcinoma, possibly of a gastrointestinal origin, a monodermal teratoma, or a borderline mucinous tumour of the testicle (BMTT) were considered. Following 12 p genetic studies and a colonoscopy, both of which found no abnormalities, a presumptive diagnosis of a BMTT was made. The patient is to have an annual urological review with a CT C/A/P and 5 yearly colonoscopies

Review and update of benign prostatic hyperplasia in general practice

Background: Benign prostatic hyperplasia (BPH) is the most common benign tumour in men. Although men with BPH often need medical or surgical management from a urologist at some point throughout the timeline of their disease, most men are initially assessed and managed by a general practitioner (GP) in the primary healthcare setting. Objectives: The aim of this article is to highlight the principles of the pathogenesis, presentation, assessment and management of BPH in a primary care setting. Discussion: Between 2009 and 2011, BPH was managed by GPs at approximately 228,000 general practice visits per annum in Australia. Several changes in pharmaceutical agents and surgical intervention have occurred over the past decade. As a result, it is imperative that GPs remain up to date with assessment and management of BPH, are aware of new therapies and understand when to refer to a urologist

Bladder neck sparing in radical prostatectomy

The role of a bladder neck sparing (BNS) technique in radical prostatectomy (RP) remains controversial. The potential advantages of improved functional recovery must be weighed against oncological outcomes. We performed a literature review to evaluate the current knowledge regarding oncological and functional outcomes of BNS and bladder neck reconstruction (BNr) in RP. A systematic literature review using on-line medical databases was performed. A total of 33 papers were identified evaluating the use of BNS in open, laparoscopic and robotic-assisted RP. The majority were retrospective case series, with only one prospective, randomised, blinded study identified. The majority of papers reported no significant difference in oncological outcomes using a BNS or BNr technique, regardless of the surgical technique employed. Quoted positive surgical margin rates ranged from 6% to 32%. Early urinary continence (UC) rates were ranged from 36% to 100% at 1 month, with long-term UC rate reported at 84-100% at 12 months if the bladder neck (BN) was spared. BNS has been shown to improve early return of UC and long-term UC without compromising oncological outcomes. Anastomotic stricture rate is also lower when using a BNS technique

Is postoperative Doppler ultrasonography useful for the early detection of asymptomatic pseudoaneurysm and prevention of haemorrhagic complications after partial nephrectomy?

Objective: To assess the clinical utility of systematic Doppler ultrasonography (DUS) after robot-assisted partial nephrectomy (PN) for the detection of renal artery pseudoaneurysm (PA) and to allow pre-emptive arterial embolization to reduce the postoperative bleeding risk. Materials and Methods: A retrospective study was conducted including all consecutive patients treated with robot-assisted PN for renal tumours between 2015 and 2017. Every patient underwent renal DUS in the early postoperative period. The presence of PA, arteriovenous malformation or collection on the DUS, as well as the incidence of haemorrhagic complications and need for transfusion/embolization were assessed. Results: Eighty-three patients were included, with a median (range) age of 58 (19–80)\ua0years. The median (range) follow-up was 5 (1–30)\ua0months. The mean (±sd) tumour size was 31 (±13.1) mm, the median (range) RENAL nephrometry score was 6 (4–11), and the mean (±sd) warm ischaemia time was 22 (±7) min. A haemostatic agent was used in 12 patients (14.5%). No patient encountered haemorrhagic complications postoperatively, and no patient required transfusion. The median (interquartile range) time to DUS postoperatively was 7 (6–8)\ua0days. DUS revealed one asymptomatic PA (1.2%), which was treated with pre-emptive embolization. This was the only patient who encountered a Clavien grade III complication, while 20 patients (24%) had a complication grade I/II. Conclusions: No haemorrhagic complications occurred in the present study population, although one asymptomatic PA was found. It was diagnosed early with DUS, allowing pre-emptive management with embolization. These results suggest the potential clinical utility of early postoperative DUS in order to screen for PA to reduce the risk of post-PN haemorrhagic complications

Development of a pelvic exenteration service at a tertiary referral centre

BACKGROUND: Over one-third of primary rectal cancers are locally advanced at diagnosis, and local recurrence of rectal cancer occurs at a rate of 3-10% following primary curative resection. Extended resectional surgery, including pelvic exenteration, is the only proven therapy with curative potential in the treatment of these cancers along with many other pelvic malignancies. A microscopically clear resection margin (R0 resection) is the predominant prognostic factor affecting overall and disease-free survival. The extent and complexity of surgery required to achieve an R0 resection is associated with significant risk of morbidity and mortality. The aim of this paper is to show that pelvic exenterations can be performed with acceptable oncological and safe perioperative results in an appropriately resourced specialist centre. METHODS: Data was collected retrospectively for 61 consecutive patients treated between June 2012 and February 2017. This included patient demographics, tumour characteristics, operative, clinical and histological data, length of hospital stay, morbidity and mortality data. RESULTS: A total of 61 patients underwent surgery. Median age was 57 years (range 27-78 years). Median length of stay was 41 days (range 6-288 days). Median operative time was 624 min (range 239-1035 min); 30-day mortality was 3.3% (n = 2). Resection rates were 91.5% - R0, 6.8% - R1 and 1.7% - R2 resections. Histologically, 86.9% - adenocarcinomas, 3.3% - squamous cell carcinomas and 9.8% - represented by leiomyosarcoma, melanoma, myxoid chondrosarcoma, non-neoplastic processes and undifferentiated carcinoma. CONCLUSION: Our experience confirms that radical resectional pelvic surgery can be safely performed with acceptable results during the establishment phase of a dedicated tertiary service
