Selected AbstractsResults of decompression surgery for pain in chronic pancreatitisHPB, Issue 4 2007J.D. Terrace Abstract Introduction. A vast majority of patients with chronic pancreatitis require regular opiate/opioid analgesia and recurrent hospital admission for pain. However, the role and timing of operative strategies for pain in chronic pancreatitis is controversial. This study hypothesized that pancreatic decompression surgery reduces analgesia requirement and hospital readmission for pain in selected patients. Patients and methods. This was a retrospective review of patients undergoing longitudinal pancreatico-jejunostomy (LPJ), with or without coring of the pancreatic head (Frey's procedure), between 1995 and 2007 in a single UK centre. Surgery was performed for chronic pain with clinical/radiological evidence of chronic pancreatitis amenable to decompression/head coring. Results. Fifty patients were identified. Thirty-six were male with a median age of 46 years and median follow-up of 30 months. Twenty-eight underwent LPJ and 22underwent Frey's procedure. No significant difference in reduction of analgesia requirement (71% vs 64%, p=0.761) or hospital readmission for pain (21% vs 23%, p=1.000) was observed when comparing LPJ and Frey's procedure. Patients were significantly more likely to be pain-free following surgery if they required non-opiate rather than opiate analgesia preoperatively (75% vs 19%, p=0.0002). Fewer patients required subsequent hospital readmission for pain if taking non-opiate rather than opiate analgesia preoperatively (12.5% vs 31%, p=0.175). Conclusions. In selected patients, LPJ and Frey's procedure have equivalent benefit in short-term pain reduction. Patients should be selected for surgery before the commencement of opiate analgesia. [source] O-11 Proposal for extending the role Of ABMSPS in reporting cervical loopsCYTOPATHOLOGY, Issue 2007K. Ellis Introduction:, The advanced biomedical scientist practitioner (ABMSP) in Cervical Cytology was established in the NHS cervical screening programme (NHSCCSP) in 2001 and there are approximately 60 ABMSPs in post. The aim of this study was to explore the potential for further expansion of their role in the NHSCSP by reporting the histology of loop excision biopsies of the cervical transformation zone (LLETZ). Methods:, The initial study included LLETZ specimens from 55 sequential patients, which, according to standard local practice had the diagnosis of CIN confirmed by cervical punch biopsy prior to the procedure. All the cases were independently examined by an ABMSP and a consultant histopathologist and reports complying with the Royal College of pathologists (RCPath) minimum data sets were assembled. The cases were reviewed at the discussion microscope and ABMSP reports were compared to the final reports issued by the histopathologist. Results:, In the preliminary findings, total agreement between ABMSP and consultant histopathologist was reached on just under 90% of cases. Of those cases that did not reach total agreement, none varied by more than one grade. There was agreement on other parameters from the RCPath minimum data sets. Discussion:, Based on our preliminary findings, it appears there may be scope for extending the role of ABMSPs to report LLETZ samples under the supervision of a histopathologist. We plan to increase the number of cases both in our department and through collaboration with other UK centres and to present evidence to the RCPath, with a view to adoption of this role by ABMSPs and development of an appropriate training scheme. [source] CD4 cell count and initiation of antiretroviral therapy: trends in seven UK centres, 1997,2003HIV MEDICINE, Issue 3 2007W Stöhr Objectives We examined whether the timing of initiation of antiretroviral therapy (ART) in routine clinical practice reflected treatment guidelines, which have evolved towards recommending starting therapy at lower CD4 cell counts. Methods We analysed longitudinal data on 10 820 patients enrolled in the UK Collaborative HIV Cohort (UK CHIC) Study, which includes seven large clinical centres in south-east England. CD4 cell and viral load measurements performed in the period between 1 January 1997 and 31 December 2003 were classified according to whether ART was subsequently initiated or deferred, to estimate the probability of ART initiation by CD4 count and viral load over time. The effect of nonclinical factors (age, sex, ethnicity, and exposure category) was analysed by logistic regression. Kaplan,Meier analysis was used to estimate the proportion of patients who had initiated ART by a particular CD4 count among ,early' presenters (initial CD4 cell count >500 cells/,L). Results There was a tendency to initiate ART at lower CD4 cell counts over time in the years 1997,2000, especially in the range 200,500 cells/,L, with little change thereafter. An estimated 34% of HIV-infected individuals having presented early initiated ART at a CD4 count <200 cells/,L. We also found an independent influence of viral load, which was particularly pronounced for CD4 <350 cells/,L. Use of injection drugs was the only nonclinical factor associated with initiation of ART at lower CD4 cell counts. Conclusions The initiation of ART in the clinics included in this analysis reflected evolving treatment guidelines. However, an unexpectedly high proportion of patients started ART at lower CD4 counts than recommended, which is only partly explained by late presentation. [source] The total percentage of biopsy cores with cancer improves the prediction of pathological stage after radical prostatectomyBJU INTERNATIONAL, Issue 6 2004Mathias H. Winkler OBJECTIVE To examine whether the simple variable ,percentage of cancer-positive biopsy cores' is a significant predictor of true pathological stage after radical prostatectomy and can be used to improve pathological stage prediction by simple means. PATIENTS AND METHODS In all, 375 patients had a radical prostatectomy for localized prostate cancer in two UK centres; 260 had complete preoperative staging information. Logistic regression was used and predicted probability graphs constructed to assess predictors of pathological stage. RESULTS In this study, only PSA (P = 0.004) and percentage cancer-positive biopsy cores (P < 0.001) were significant predictors of pathological stage. The final model was an acceptable classifier for pathological stage (area under the receiver operating characteristic curve 0.76, specificity 85%, sensitivity 47%). A patient with a PSA of 10 ng/mL and one of six cores positive for cancer would have a predicted probability of extraprostatic disease of 20%, whereas the same patient with all six biopsy cores positive would have a predicted probability of extraprostatic disease of 80%. CONCLUSIONS The percentage of cancer-positive biopsy cores significantly predicts the disease stage after radical prostatectomy. This variable is easy to obtain by the clinician and avoids the need to estimate the percentage of biopsy tissue infiltrated by cancer. This readily available information can easily be computed and may help to counsel patients about realistic expectations of organ-confined disease in relation to surgery as a treatment option. [source] Sacral nerve stimulation for faecal incontinence in the UK,BRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 6 2004M. E. D. Jarrett Background: Sacral nerve stimulation (SNS) is an effective therapy for faecal incontinence. Published studies derive largely from single centres and there is a need to determine the broader applicability of this procedure. Methods: Prospective data were collected for all patients undergoing SNS in the UK. Records were reviewed to determine the outcome of treatment. Results: In three UK centres 59 patients underwent peripheral nerve evaluation, with 46 (78 per cent) proceeding to permanent implantation. Of these 46 patients (40 women) all but two had improved continence at a median of 12 (range 1,72) months. Faecal incontinence improved from a median (range) of 7·5 (1,78) to 1 (0,39) episodes per week (P < 0·001). Urgency improved in all but five of 39 patients in whom ability to defer defaecation was determined, improving from a median of 1 (range 0,5) to 10 (range from 1 to more than 15) min (P < 0·001). Maximum anal squeeze pressure and sensory function to rectal distension changed significantly. Significant improvement occurred in general health (P = 0·024), mental health (P = 0·008), emotional role (P = 0·034), social function (P = 0·013) and vitality (P = 0·009) subscales of the Short Form 36 health survey questionnaire. There were no major complications. One implant was removed. Conclusion: SNS is a safe and effective treatment, in the medium to long term, for faecal incontinence when conservative treatment has failed. Copyright © 2004 British Journal of Surgery Society Ltd.

Sheen Background: This paper reports a 7-year experience of cryoablation for colorectal and non-colorectal liver metastases. Methods: A retrospective review was undertaken of patients treated in two adjacent UK centres in the north-west of England. Results: Over a 7-year period (1993,2000), 57 patients underwent cryotherapy for malignant hepatic tumours (41 colorectal, 16 non-colorectal). In the patients with colorectal metastases, preoperative carcinoembryonic antigen (CEA) levels fell significantly, from a mean of 444·1 to 6·22 µg/l (P = 0·002). One patient died, two developed cryoshock and six had cardiorespiratory complications. All patients with colorectal metastases subsequently received 5-fluorouracil-based chemotherapy. The remaining 16 patients with non-colorectal tumours (seven neuroendocrine metastases, five hepatocellular carcinomas, three sarcomas, one cholangiocarcinoma) all received cryotherapy alone, with no major complications. The median survival for patients with non-colorectal metastases was 37 months, compared with 22 months for those with colorectal metastases (P = 0·005). Conclusion: Hepatic cryotherapy is effective and safe, as demonstrated by the significant reduction in postoperative CEA concentration and the low risk of complications. However, this initial short-term success was not reflected in 5-year survival rates. Cryotherapy for non-colorectal metastases had a greater long-term survival benefit and is a useful means of controlling symptoms. © 2002 British Journal of Surgery Society Ltd [source] | ||||||||||
