OBJECTIVE: To prospectively compare the efficacy of bi-basal vs bi-apical periprostatic nerve block (PPNB) during 12-core prostate biopsy guided by transrectal ultrasonography (TRUS), and to evaluate the pain experienced on inserting the probe compared to the biopsy procedure, as PPNB with lignocaine local anaesthesia has been used for over a decade for minimizing pain during prostatic biopsy. PATIENTS AND METHODS: In all, 143 men who were to have a TRUS-guided prostate biopsy were systematically randomized to two groups, to receive PPNB at the apex or base. A 10-cm visual analogue score was used to record the pain experienced during probe insertion, the biopsy and just before to leaving the department . RESULTS: The mean pain score on biopsy in the apical group was similar to that of the basal group (apex 1.9, base 1.6, P = 0.36). Probe introduction produced a significantly higher pain score (probe 2.2, biopsy 1.7, P < 0.001) than at the biopsy. CONCLUSIONS: Patients who experienced greater pain with the introduction of the probe also reported more pain with the biopsy procedure. The site of local anaesthetic before prostatic biopsy showed no significant difference in pain scores. Older men tolerated the procedure better. Analgesia after PPNB at near either the apex or base appears equal, regardless of the site of injection. We suggest that topical perianal anaesthetic agents could significantly reduce not only pain perception, but also improve tolerance. 相似文献

Background: Use of ultrasound by anaesthesiologists performing regional blocks is rapidly gaining popularity. The aims of this review were to summarize and update accumulating evidence on ultrasound-guided nerve blocks, with an emphasis on the clinical relevance of the results and to critically appraise changing standards in regional anaesthesia.
Methods: A search of MEDLINE and EMBASE (1966 to 31 December 2007) was conducted using the following free terms: 'ultrasound and regional anesthesia', 'ultrasound and peripheral block' and 'ultrasound and nerve and block'. These were combined with the MESH terms 'nerve block' and 'ultrasonography'. The following limits were applied: studies with abstracts, only in humans, published in core clinical journals. Trial type: meta-analysis, randomized-controlled trial and clinical trial.
Results: When peripheral nerves are adequately imaged by ultrasound, the concomitant use of nerve stimulation offers no further advantage. However, several studies reported problems with obtaining satisfactory images in some patients. Ultrasound guidance significantly shortened the block performance time and/or reduced the number of needle passes to reach the target in all comparative studies. The occurrence of paraesthesia during block performance was also reduced, but not the incidence of short-lasting post-operative neuropraxia. The frequency of accidental vascular punctures may be lower, but the data are contradictory. Block onset time was significantly shortened. Block duration was longer in children, but not in adults. Ultrasound also allowed dose reduction of the local anaesthetic (LA).
Conclusions: Ultrasound guidance shortens the block performance time, reduces the number of needle passes and shortens the block onset time. Blocks may be performed using lower LA doses. 相似文献

Objective: The aim of this study was to determine whether robot‐assisted laparoscopic radical prostatectomy (RALP) performed within either 2 or 4 weeks of prostate biopsy is associated with surgical difficulty or immediate postoperative outcome. Methods: Of the 121 patients that underwent RALP at our institution, 104 patients were prospectively included. Patients were sequentially divided into three groups: first patient in group A (interval from biopsy to RALP: 2 weeks), second patient in group B (2–4 weeks), third patient in group C (more than 4 weeks), fourth patient in group A, and so on. The clinical, operative, pathological, and postoperative functional data were collected. Results: Group A consisted of 31 patients, group B of 33, and group C of 40 patients. Median patient age and median follow up were 61.1 years and 14.1 months, respectively. In group A, mean estimated blood loss was significantly higher than the other two groups, even though there was no significant difference in the mean console time. Postoperative complications did not make any difference among the groups. In the multivariable analysis, the interval from biopsy to surgery did not affect operative times or surgical margins, or the immediate postoperative outcomes (e.g. recovery of erectile function, continence, and biochemical recurrence). Conclusion: A short interval for less than two weeks between the prostate biopsy and the RALP seems to be feasible and safe. Further studies with larger samples are needed to corroborate these findings. 相似文献

Aim To determine current delays in diagnosis and treatment of bowel cancer, when and why they occur, and what effect they have on survival. Method A detailed review of the literature based on the development of the GP referral guidelines in 2000. Results There is no evidence of a reduction in the delay to diagnosis and treatment of bowel cancer over the last 60 years. There is no strong theoretical basis for a benefit from earlier diagnosis of symptomatic bowel cancer and this is consistent with observational studies. Conclusion Campaigns to earlier diagnose bowel cancer will not be successful unless new strategies are developed. There is substantial evidence that earlier diagnosis of symptomatic bowel cancer will not improve survival in the majority of patients. However as excessive delays still occur in some patients it is reasonable to continue to aim to diagnose and treat all bowel cancer within 6 months of the onset of symptoms with an overall median of 3–4 months. 相似文献

Cryptogenic cirrhosis (CC) is diagnosed in 5-30% of cirrhotic patients overall and 7% of patients who undergo liver transplantation for cirrhosis. In our series of patients transplanted for CC, pre-transplant clinical and histological data and the post-transplant course were reexamined in an attempt to identify the aetiology. Among the 881 patients transplanted in our centre between 1987 and 2000, 28 patients with a median age of 46 yr (range: 18-69) at transplantation were initially classified as having CC. Two patients were excluded because of intense ischaemic lesions caused by chemoembolization prevented histological analysis of the native liver (n = 1) and because of cryptic HBV infection (n = 1). Among the remaining 26 patients, four groups were individualized: (i) patients with chronic inflammatory liver disease with autoimmune features (n = 14, 54%); (ii) patients with features suggestive of non-alcoholic fatty liver disease (n = 3, 11.5%); (iii); patients with incomplete septal cirrhosis (ISC) and vascular liver disease (n = 3), and (iv) patients with unresolved CC (n = 6, 23%). In the autoimmune liver disease group, the median International Autoimmune Hepatitis score was 12.5 (range: 11-19) after reevaluation and review of the post-transplantation course was helpful to confirm the diagnosis with the occurrence of active graft hepatitis in nine patients, with autoantibodies in five patients. The vascular group was characterized by lesions of obliterative portal venopathy and ISC in all native livers. Diagnosis of NAFLD was based on the clinical background of obesity and/or type 2 diabetes and the presence of steatosis or steatohepatitis in native livers and graft biopsies. A definite aetiological diagnosis can be achieved in the majority of patients initially diagnosed with CC. Autoimmune liver disease emerged as the main aetiology (14 of 26 patients, 54%) and frequently recurred on the grafted liver (nine cases). In all cases a precise diagnosis is obviously of practical interest for better management of post-transplant survey and treatment. 相似文献

BackgroundOf the currently available prostate-specific membrane antigen (PSMA) positron emission tomography (PET) tracers, although 68Ga-PSMA-11 and 18F-DCFPyL have been approved by the US Food and Drug Administration (FDA), both tracers are excreted rapidly through the urinary tract, resulting in strong accumulation in the bladder and blurring the prostate.18F-PSMA-7Q is a novel quinoline-containing PSMA PET tracer developed by our team, which is primarily excreted through the liver. It can reduce the incidence of urine-induced false-positives in the prostate. We aimed to explore the diagnostic efficacy of 18F-PSMA-7Q PET/computed tomography (CT), and when 18F-PSMA-7Q PET/CT can be used instead of prostate biopsy to diagnose prostate cancer.MethodsPatients who underwent 18F-PSMA-7Q PET/CT for prostate cancer staging or prostate biopsy guidance at our institution between July 2020 and December 2021 were retrospectively enrolled. Molecular imaging PSMA (miPSMA) scores were assigned for intra-prostatic lesions according to the Prostate Cancer Molecular Imaging Standardized Evaluation (PROMISE) criteria, and the diagnostic efficacy of 18F-PSMA-7Q PET/CT for different miPSMA scores was evaluated using pathological diagnosis as the gold standard.ResultsOf the 125 enrolled patients, 101 had prostate cancer, and 24 had prostatic hyperplasia or prostatitis. miPSMA ≥2 was the optimal diagnostic threshold, and area under curve (AUC) was 0.948, the sensitivity and specificity were 91.1% and 83.0%. The prostate cancer detection rates of 18F-PSMA-7Q PET/CT were 14.3% (3/21), 60.0% (6/10), 96.7% (58/60), and 100% (34/34) for patients with miPSMA scores of 0, 1, 2, and 3, respectively. There was no significant difference in the detection rate of prostate cancer between groups with miPSMA scores of 2 and 3, but there were significant differences between any other 2 groups.ConclusionsThe prostate cancer detection rate of 18F-PSMA-7Q PET/CT was high for lesions with greater miPSMA scores of 2 and 3. For patients with a high miPSMA score, particularly those with a miPSMA score of 3, prostate biopsy can be omitted and prostate cancer-related treatment can be considered. 相似文献

Achalasia is a rare motor disorder of the esophagus, characterized by the absence of peristalsis and impaired swallow-induced
relaxation. In the past decade, evidence has been accumulated suggesting that achalasia may be an immune-mediated inflammatory
disorder. With the advent of minimally invasive surgery, laparoscopic Heller myotomy (LHM) has slowly shifted the treatment
of achalasia toward the greater use of surgical therapy. The goal of both surgical and nonsurgical treatment is to eliminate
the outflow obstruction afforded by a nonrelaxing sphincter, relieving dysphagia and maintaining a barrier against gastroesophageal
reflux (GER). Endoscopic botulinum toxin injection (EBTI) is safe, easy to perform, inexpensive, and effective in aged patients,
and it is especially effective when the lower esophageal pressure is hypertonic. This therapeutic option is reserved for patients
too ill to undergo any surgical procedure. Pneumatic dilation (PD) has been shown to be an effective and inexpensive treatment
with few adverse effects. The long-term success rate of PD seems to drop progressively over time. Heller myotomy (HM) has
shown the best clinical efficacy in achalasia as a first-line treatment. Multiple endoscopic treatments are associated with
poorer outcomes after HM. EBTI also makes LHM more difficult and results in a worse surgical outcome. The inferior symptomatic
outcomes after thoracoscopic HM may be caused by the difficulty in extending an adequate myotomy onto the stomach from the
chest and the inability to create a fundoplication. LHM with Dor’s fundoplication (LHM + Dor) is effective and is safer procedure
for avoiding GER, dysphagia, mucosal perforation, and a pseudodiverticulum. LHM + Dor is also effective in the presence of
sigmoid achalasia, but the clinical result is not as good as nonsigmoid achalasia. A few patients need esophagectomy for surgical
failure of HM. However, considering the risk of esophagectomy, LHM + Dor is the first treatment option for patients with achalasia
regardless of the degree of esophageal dilatation. This procedure is therefore considered to be an effective and safe treatment
for patients of any age or with any condition. 相似文献

Background:To construct a modified model for reporting and grading of postoperative complications after the mid-urethral sling (MUS) procedure based on the Clavien-Dindo classification. In addition, complications of three different types of MUS were compared.Materials and methods:A PubMed search for postoperative complication after MUS was carried out for the period between January 1990 and July 2018. Reported complications were stratified in a plate form designed in accordance with grades of the Clavien-Dindo classification. Then, the proposed model was applied on reported complications in 160 females who underwent three different procedures of MUS (transvaginal tape [TVT], transobturator tape [TOT], and autologous fascial sling) with a minimum follow-up of 24 months.Results:The mean ± SD age at time of surgery was 46 ± 7 years. TVT was carried out in 75 (47%) patients, TOT in 40 (25%), and fascial sling in 45 (28%). The total number of complications was 62 in 43 (26.8%) patients. The vast majority of complications were Grade I and Grade II 19 (12%) and 21 (13%) out of 160 patients, respectively. Transient postoperative voiding difficulty (Grade II) and de novo urgency (Grade II) were the most prevalent complications in the fascial sling method (15.4% for each), whereas transient thigh pain (Grade II) was the most frequently reported complication after TOT (10%). Life-threatening vascular injury (Grade IV-a) was a serious complication in TVT cases.Conclusions:Postoperative complications of the MUS could be graded according to Clavien''s classification. The vast majority of complications were Graded I or II. TVT can cause serious life-threatening complications. 相似文献
