Management of small (T1-T2) anal margin squamous cell carcinoma: clinical outcomes following local excision alone.

AIM: Squamous cell carcinomas of the anus are normally treated with synchronous chemoradiotherapy (CRT). Small, localized anal margin tumours may be adequately treated by local excision (LE) alone. This study aims to investigate the outcomes of patients with anal margin tumours treated with LE alone, reserving the use of CRT for salvage on local recurrence (LR). METHODS: Patients with small, localized (stage I/IIA) anal margin tumours treated by LE from October 1999 to September 2018 were identified. The effect of tumour size and resection margin on LR risk was analysed. Outcomes of overall survival and disease-free survival were measured. RESULTS: Fifty-five patients with anal margin tumours were identified. Overall 5-year LR, overall survival and disease-free survival rates were 8%, 86% and 82% respectively. Of the seven LRs, five were successfully salvaged with CRT with no further recurrence and two were not fit for CRT. Resection margins in non-fragmented tumours and tumour size did not significantly influence LR risk. CONCLUSIONS: Most small, localized anal margin tumours can be adequately treated by LE alone with low LR rates. Most patients who developed LR were salvaged using CRT, with no cancer-related deaths reported.

Patient experience of telephone consultations in gynaecology: a service evaluation.

OBJECTIVE: To investigate patient perspective of telephone consultations (TCs) in gynaecology and identify which patients benefit most from a telemedicine system. DESIGN: Service evaluation. SETTING: Gynaecology outpatient services at a tertiary referral hospital. POPULATION: Patients who received a TC during May and June 2020. METHODS: Postal questionnaire combining three validated tools: QQ-10, Patient Enablement Index (PEI) and National Health Service Friends and Family Test (NHS-FFT). Quantitative data and free text responses were analysed. MAIN OUTCOME MEASURES: Responses to QQ-10, PEI and NHS-FFT. RESULTS: In total, 1307 patients were contacted and 504 patients responded (39%). Most (89%) described their experience as 'Very good' or 'Good' (NHS-FFT). Positive themes from responses included 'convenience', 'effectiveness' and 'equivalent care'. QQ-10 responses demonstrated a high Value score of 79 (0-100) and a low Burden score of 15. PEI scores suggested that most patients felt better or much better able to understand and cope with their condition following TC. The majority of patients (77%) would 'Strongly agree' or 'Mostly agree' to a repeat TC. Regarding patient outcomes, 21% were discharged and 71% required follow up. Menopause, fertility and endometriosis follow-up clinic patients benefited most from TC. Gynaecology-oncology patients found TC least acceptable. CONCLUSION: We report a large questionnaire survey of patient experience of TC in gynaecology. Telemedicine is convenient, acceptable and effective for conducting care in selected groups. TC can support patients in communicating intimate symptoms. TWEETABLE ABSTRACT: Telephone consultations are a convenient, acceptable and effective medium for conducting patient care in gynaecology.

Electronic personal assessment questionnaire for vascular conditions (ePAQ-VAS): development and validity.

BACKGROUND: This paper describes the development and validation of an electronic personal assessment questionnaire for vascular conditions (ePAQ-VAS) that captures the symptomatology, quality of life and clinically relevant data of patients presenting to vascular services. METHODS: A two-stage survey was conducted in patients attending a tertiary vascular department. Patients completed the ePAQ-VAS remotely online, or on site using an electronic tablet. In the first stage of the survey, the responses were used to perform confirmatory factor analysis to assess the construct validity and remove redundant items. The internal reliability of disease-specific scales was investigated. In the second stage of the survey, the acceptability, known-group validity, test-retest reliability, and responsiveness of ePAQ-VAS was assessed. RESULTS: In total, 721 patients completed ePAQ-VAS. Their mean(s.d.) age was 63·5(15·7) years and 468 (64·9 per cent) were men. Some 553 patients (76·7 per cent) completed the questionnaire in clinic and the remainder completed the questionnaire online. The results of the confirmatory factor analysis confirmed the conceptual model for ePAQ-VAS structure and eliminated six items. Internal reliability was acceptable for all the scales (Cronbach's α greater than 0·7). The test-retest reliability measured by the intraclass correlation coefficient ranged from 0·65 to 0·99. The results showed that the instrument was responsive over time with the standardized response mean ranging from 0·69 to 1·60. CONCLUSION: ePAQ-VAS is a holistic data-collection process that is relevant to vascular service users and has potential to contribute to patient-focused care and the collection of aggregate data for service evaluation. A demonstration version of the final version of ePAQ can be viewed at http://demo-questionnaire.epaq.co.uk/home/project?id=VASC_1.7&page=1.

ANTECEDENTES: Este artículo describe el desarrollo y la validación de un cuestionario electrónico de evaluación personal para enfermedades vasculares (ePAQ-VAS) que incluye la sintomatología, la calidad de vida y los datos clínicamente relevantes para los pacientes que son atendidos en los servicios de patología vascular. MÉTODOS: Se llevó a cabo una encuesta en dos fases entre los pacientes atendidos en un servicio de patología vascular de tercer nivel. Los pacientes completaron el cuestionario ePAQ-VAS a distancia en línea o bien en el centro hospitalario mediante una tableta electrónica. En la primera fase de la encuesta, las respuestas se utilizaron para realizar un análisis factorial de confirmación para evaluar la validez del diseño y eliminar los elementos redundantes. Se investigó la fiabilidad interna de las escalas específicas de la enfermedad. En la segunda fase de la encuesta, se evaluó la aceptabilidad, la validez de grupo conocida, la fiabilidad test-retest y la capacidad de respuesta del ePAQ-VAS. RESULTADOS: En total, 721 pacientes completaron el ePAQ-VAS, la edad media fue de 63,5 años (DE 15,7); el 64,9% eran varones (468); el 76% de los pacientes (553) completaron el cuestionario en la clínica y los pacientes restantes lo hicieron electrónicamente a distancia. Los resultados del análisis factorial de confirmación confirmaron el modelo conceptual para la estructura ePAQ-VAS y eliminaron seis ítems. La fiabilidad interna fue aceptable para todas las escalas (alfa de Cronbach > 0,7). La fiabilidad test-retest medida por el coeficiente de correlación intraclase osciló entre 0,65-0,99. Los resultados mostraron que el instrumento responde con el tiempo con una media de respuesta estandarizada que varía de 0,69 a 1,60. CONCLUSIÓN: El ePAQ-VAS es un proceso holístico de recopilación de datos que es relevante para los usuarios de servicios de patología vascular y tiene el potencial de contribuir a la atención centrada en el paciente y a la recopilación de datos agregados para la evaluación del servicio.

Anti-TNF therapy is not associated with an increased risk of post-colectomy complications, a population-based study.

AIM: Previous studies have raised concerns that the use of anti-tumour necrosis factor (anti-TNF) therapy in patients with ulcerative colitis (UC) undergoing surgery may increase the risk of postoperative complications. We have taken a population-based approach to investigate whether there is an association between anti-TNF therapy and postoperative complications in UC patients undergoing subtotal colectomy. METHOD: Hospital Episode Statistics (HES) data and procedural coding were used to identify all patients in England between April 2006 and March 2015 undergoing subtotal colectomy for UC. Patients were grouped into those who received anti-TNF therapy within 12 or 4 weeks of surgery and those who did not. The incidence of postoperative complications was evaluated by HES coding and compared between groups. RESULTS: In all, 6225 UC patients underwent subtotal colectomy. 753 patients received anti-TNF therapy within 12 weeks prior to surgery (418 within 4 weeks). There was no difference in postoperative complications between groups although groups were not comparable for age and comorbidities. Logistic regression with complications as the outcome variable did not show any significant association between anti-TNF therapy and complications. Colectomy performed during an unplanned admission (vs planned admission) and smoking were associated with complications. CONCLUSION: This large population-based study does not demonstrate any association between preoperative anti-TNF therapy and postoperative complications in UC patients undergoing subtotal colectomy. The only variables associated with complications were colectomy performed during an unplanned admission and smoking.

Introduction of enhanced recovery for elective caesarean section enabling next day discharge: a tertiary centre experience.

BACKGROUND: The widespread adoption of enhanced recovery programmes in various surgical specialties has resulted in patient benefits including reduced morbidity, reduced length of stay and an earlier return to normal activities. This evidence, along with the increased financial pressures in the UK National Health Service, has led many units to consider introducing such a programme for obstetric surgery. We report our experience in setting up an enhanced recovery programme for women undergoing elective caesarean section and a prospective analysis of factors that influence length of stay. METHODS: An enhanced recovery pathway was designed by a multidisciplinary team and introduced in March 2012. Factors influencing length of stay were determined using a log normal model. RESULTS: The proportion of women discharged on Day 1 increased from 1.6% in the first quarter of 2012 to 25.2% in the first quarter of 2014. The 30-day readmission rate was 4.4% for those discharged on Day 1 and 5.6% for Day 2. Earlier gestation, multiple birth, intention to breast feed, longer surgery and more time in the post-anaesthesia recovery unit were all independently associated with a longer postoperative stay. Women presenting for obstetric surgery with the indication "one previous caesarean section" were more likely to leave hospital earlier compared to most other indications. CONCLUSION: An enhanced recovery programme was successfully introduced into our unit. Many of the interventions were straightforward and could be adopted easily elsewhere.

Responsiveness of the electronic Personal Assessment Questionnaire-Pelvic Floor (ePAQ-PF).

This study aimed to evaluate the responsiveness of the electronic Personal Assessment Questionnaire-Pelvic Floor (ePAQ-PF) in women undergoing surgery for pelvic floor disorders. Fifty-four women undergoing tension-free vaginal tape (TVT) and 47 women undergoing prolapse surgery completed ePAQ-PF at baseline and 3 months postoperatively. Responsiveness was calculated using effect sizes, standardized response means, responsiveness statistic, and minimally important difference. In the TVT group, the largest effect sizes were seen in the urinary domains for stress urinary incontinence (2.4), quality of life (2.2), and overactive bladder (0.9). In the prolapse group, the largest effect sizes were seen in the vaginal domains for prolapse (2.1) and quality of life (1.0). ePAQ-PF is responsive to change in women undergoing TVT or prolapse surgery in the salient and expected domains of stress incontinence and prolapse and quality of life and can be recommended for outcome measurement in this context.

Retrospective analysis of pre- and peri-operative imaging in confirmed proximal colonic cancers--possible implications for screening flexible sigmoidoscopy.

OBJECTIVE: Faecal occult blood testing is being introduced for population screening in the United Kingdom. Flexible sigmoidoscopy may provide a viable alternative. The outcomes of the flexible sigmoidoscopy trial are awaited but the most obvious disadvantage is that only the lower third of the colon is examined and proximal pathology cannot be excluded. The relationship between proximal pathology and distal findings at flexible sigmoidoscopy is uncertain. The aim of this study was to determine the incidence of distal neoplasia in patients with confirmed proximal cancers of the colon. METHOD: All confirmed proximal colonic cancers (defined as those proximal to the splenic flexure) were identified from a database of pathology specimens at a single centre between January 1999 and August 2006. A retrospective analysis of preoperative and peri-operative mucosal imaging (contrast enema, colonoscopy and CT colonography) was conducted to identify any distal neoplasia in these patients. RESULTS: A total of 348 patients were identified. Pre- or peri-operative mucosal imaging was identified in 231 (66%) and 49 (21%) had distal neoplasia. Nineteen (8%) of these patients would have gone on to have a colonoscopy based on the UK flexible sigmoidoscopy trial protocol and 92% of the cohort would not have had a colonoscopy. CONCLUSION: Nearly 80% of confirmed proximal cancers in our series did not have any demonstrable distal neoplasia. Only 8% of our cohort would have proceeded to colonoscopy. A very significant number of proximal cancers would not have been detected.

Metachronous squamous-cell carcinoma of the colon and treatment of rectal squamous carcinoma with chemoradiotherapy.

Rectal squamous-cell carcinoma is a rare tumour with an incidence of less than 1 per 1000 cases. We report such a case treated with chemoradiotherapy. The patient developed a metastasis in the spleen and a further squamous tumour in the right colon, both of which were successfully resected. No histological evidence of recurrent rectal tumour has been found. Two years following presentation, the patient remains disease-free although symptomatic from a radiotherapy-induced stricture of the rectum.

Methods of repair for obstetric anal sphincter injury.

BACKGROUND: Anal sphincter injury during childbirth - obstetric anal sphincter injuries (OASIS) - is associated with significant maternal morbidity including perineal pain, dyspareunia and anal incontinence. Anal incontinence affects women psychologically and physically. Many do not seek medical attention because of embarrassment. The two recognised methods for the repair of damaged external anal sphincter (EAS): are end-to-end (approximation) repair and overlap repair. OBJECTIVES: To compare the effectiveness of overlap repair versus end-to-end repair following OASIS in reducing subsequent anal incontinence, perineal pain, dyspareunia and improving quality of life. SEARCH STRATEGY: We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 January 2006), MEDLINE (January 1966 to 31 January 2006), EMBASE (January 1974 to 31 January 2006), SciSearch (January 1974 to 31 January 2006) and conference proceedings of obstetrics and gynaecology, surgery and coloproctology. SELECTION CRITERIA: Randomised controlled trials comparing different techniques of immediate primary repair of EAS following OASIS. DATA COLLECTION AND ANALYSIS: Trial quality was assessed independently by all authors. MAIN RESULTS: Three eligible trials, of grade A quality, involving 279 women, were included. There was considerable heterogeneity in the outcome measures, time points and reported results. Meta-analyses showed that there was no statistically significant difference in perineal pain (relative risk (RR) 0.08, 95% confidence interval (CI) 0.00 to 1.45, one trial, 52 women), dyspareunia (RR 0.62, 95% CI 0.11 to 3.39, one trial, 52 women), flatus incontinence (RR 0.93, 95% CI 0.26 to 3.31, one trial, 52 women) and faecal incontinence (RR 0.07, 95% CI 0.00 to 1.21, one trial, 52 women) between the two repair techniques at 12 months but showed a statistically significantly lower incidence in faecal urgency (RR 0.12, 95% CI 0.02 to 0.86, one trial, 52 women) and lower anal incontinence score (weighted mean difference -1.70, 95% CI -3.03 to -0.37) in the overlap group. Overlap technique was also associated with a statistically significant lower risk of deterioration of anal incontinence symptoms over 12 months (RR 0.26, 95% CI 0.09 to 0.79, one trial, 41 women). There was no significant difference in quality of life. AUTHORS' CONCLUSIONS: The limited data available show that compared to immediate primary end-to-end repair of OASIS, early primary overlap repair appears to be associated with lower risks for faecal urgency and anal incontinence symptoms. As the experience of the surgeon is not addressed in the three studies reviewed, it woudl be inappropriate to recommend one type of repair in favour of another.

The first 18 months of a new perineal trauma clinic.

Anal incontinence after childbirth is both distressing and disabling. A perineal trauma clinic was set up at the Birmingham Women's Hospital with an obstetrician, a urogynaecologist and a colorectal surgeon to improve the follow-up of women with obstetric anal sphincter injury or childbirth-precipitated anal incontinence. Fifty-five women attended the clinic. Forty-one had sustained a recognised obstetric anal sphincter injury at delivery and of these women, 61% were symptomatic with 22% leaking solid or liquid faeces. Fourteen women attended with anal incontinence who had not been recognised as sustaining an anal sphincter injury at the time of delivery. Eleven women were offered a secondary surgical repair of their anal sphincter defect. Seven accepted surgical treatment and 85% (six) were continent following surgery. A perineal trauma clinic offers an opportunity for early assessment and reduction of morbidity from childbirth-related anal incontinence.

The acute effect of magnetic stimulation of the pelvic floor on involuntary detrusor activity during natural filling and overactive bladder symptoms.

OBJECTIVE: To evaluate the effect of magnetic stimulation of the pelvic floor (MSPF) on involuntary detrusor activity observed during natural filling, and on the overactive bladder symptom complex. PATIENTS AND METHODS: Eighteen women with detrusor overactivity on conventional cystometry underwent ambulatory urodynamic monitoring over two filling cycles. Fluid intake was standardized, provocative manoeuvres applied at regular intervals and symptoms documented contemporaneously. During the second filling cycle MSPF was delivered whenever the detrusor pressure increased by > 5 cmH2O. The women were subsequently treated with MSPF for 6 weeks; their lower urinary tract symptoms were assessed before and after treatment. RESULTS: Comparing the second (stimulated) cycle with the first (unstimulated) cycle, cystometric capacity was higher (373 vs 224 mL, P < 0.03). and involuntary detrusor activity of shorter duration (370 vs 427 s, P < 0.82) and lower amplitude (53 vs 63 cmH2O, P < or = 0.05). All women tolerated the procedure comfortably, but nine found it too time-consuming and withdrew. In the nine women who completed treatment there was no consistent change in overactive bladder symptoms. CONCLUSIONS: In this pilot study, MSPF during natural filling was associated with a decrease in the amplitude of involuntary detrusor contractions and a significant increase in cystometric capacity. However, MSPF had a variable effect on sensations of urgency, both acutely and after treatment, and currently there is no evidence to suggest that MSPF has an enduring effect on symptoms of the overactive bladder.

Development and validation of a questionnaire for the assessment of bowel and lower urinary tract symptoms in women.

OBJECTIVE: To develop a simple but sensitive instrument to evaluate and document symptoms of both bowel and urinary dysfunction in women. DESIGN: A 22-item questionnaire covering a range of bowel and urinary symptoms was developed and underwent rigorous psychometric testing. SETTING: The gynaecology departments of three hospitals, a urogynaecology clinic, a functional bowel clinic and a general practice. POPULATION: Six hundred and thirty women, comprising four groups: 1. women awaiting hysterectomy (n = 379), 2. women following hysterectomy (n = 45), 3. women referred with functional bowel and/or urinary symptoms (n = 65), 4. asymptomatic controls (n = 141). MAIN OUTCOME MEASURES: The content, construct and criterion validity, internal consistency, reliability and responsiveness of the questionnaire were measured. RESULTS Peer and patient reports and missing data patterns supported face and content validity. Factor analysis showed a clinically relevant four-factor structure with low content replication able to distinguish between patient groups, indicating good internal structure. Comparison with clinical, anorectal physiological, videoproctographic, transit time and urodynamic test results provide provisional indication of criterion validity. Key domain question analysis and Cronbach's alphas showed internal consistency. Kappa values demonstrated good test-retest reliability and key question correlation over time proved responsiveness. CONCLUSIONS: Our findings support the suitability, clinical validity, reliability and responsiveness of a simple questionnaire, which is sensitive to the constraints of clinical practice. The authors recommend its use in health care evaluation research assessing the effects of pelvic surgery and as a useful tool in comparing treatment efficacy.

A scoring system for the assessment of bowel and lower urinary tract symptoms in women.

OBJECTIVE: To develop a simple scoring system for a validated 22-item questionnaire used to assess bowel and urinary dysfunction in women. SETTING: A urogynaecology clinic, a functional bowel clinic, a district general hospital and a general practice. POPULATION: One hundred and one women referred with functional bowel and/or urinary symptoms and 131 asymptomatic controls. METHODS: A user manual has been prepared. Individual responses to questions are categorised into normal and abnormal and odds ratio tests applied to reflect their sensitivity. RESULTS: Scoring methods have been detailed, and appropriate and sensitive cutoff points defined. CONCLUSIONS: The use of this validated questionnaire is now aided by a user manual, facilitating health care evaluation research into the effects of pelvic surgery on pelvic floor symptomatology. A simple scoring system is provided, making the questionnaire a valuable and accessible research tool.

Conventional and ambulatory urodynamic findings in women with symptoms suggestive of bladder overactivity.

PURPOSE: We compared ambulatory urodynamics and conventional video cystometry findings in women with symptoms of bladder overactivity. MATERIALS AND METHODS: In a prospective randomized crossover study 106 women with symptoms of urinary urgency with or without incontinence were comprehensively investigated by video cystometry and ambulatory urodynamics in random order. In addition, all women completed a validated symptoms questionnaire and voiding diary. RESULTS: Involuntary detrusor activity was detected in 32 and 70 cases on video cystometry and ambulatory urodynamics, respectively (p <0.001). Video cystometry done according to International Continence Society standards diagnosed detrusor instability in 4 women with no involuntary detrusor activity on ambulatory urodynamics. Involuntary detrusor activity resulting in incontinence was observed in 39 cases on ambulatory urodynamics, including 20 (51%) with stable video cystometry results. Stress incontinence was diagnosed in 42 cases on video cystometry and in 34 on ambulatory urodynamics (p = 0.629). Increasingly severe urge and stress incontinence reported in the symptoms questionnaire correlated positively with the subsequent detection of detrusor overactivity and stress incontinence, respectively, on the 2 urodynamic tests. CONCLUSIONS: In contrast to video cystometry, ambulatory urodynamics provides objective evidence of clinically important bladder overactivity in the majority of women with symptoms suggestive of bladder overactivity. The correlation of symptoms with ambulatory urodynamic findings implies that greater reliance may be placed on symptomatic diagnosis of bladder overactivity. Improved objective assessment of detrusor function provided by ambulatory urodynamics has implications for the definition of bladder overactivity and relevance of conventional cystometry in this context. In women who complain of urgency stable conventional cystometrography findings should be interpreted with caution.

Transurethral implantation of macroplastique for the treatment of female stress urinary incontinence secondary to urethral sphincter deficiency.

OBJECTIVE: To assess the results of transurethral implantation of Macroplastique in women with stress incontinence secondary to urethral sphincter deficiency using subjective and objective outcome measures. METHODS: A total of 60 women with genuine stress incontinence secondary to intrinsic urethral sphincter deficiency were treated with transurethral implantation of Macroplastique. The patients had undergone a mean of 1.9 (range 0-7) previous episodes of continence surgery. Up to three treatment episodes were used, if necessary. The outcome was assessed by telephone interview (56 patients, mean follow-up period 19 months) and videocystometry (41 patients, mean follow-up period 16 months). Transurethral ultrasound scanning was performed in a further 9 patients. RESULTS: Symptomatically, 19.6% of the women interviewed by telephone considered themselves cured of their incontinence or were no longer using pads. A further 41.1% said their symptoms had significantly improved. Pad usage was reduced from a median of five to three pads per day (p < 0.001). Videocystometry in 41 women (mean follow-up period 16 months) was normal in 16 patients (39%) and showed genuine stress incontinence in 18 (43.9%) and detrusor instability in 12 patients (29.3%). Overall, 71.4% stated that they would undergo the procedure again under the same circumstances, and 80.4% would recommend this form of treatment to a friend with the same condition. Transurethral ultrasound scanning was performed in 9 patients (5 subjectively improved or cured, 1 patient with persistent symptoms but normal cystometry, and 3 patients with persistent genuine stress incontinence). Hyperechoic foci were seen surrounding the proximal urethra, consistent with implanted Macroplastique boluses. When completely encircling the urethra, the outcome was generally good. A total of 10 patients have undergone or are awaiting open surgery, and 3 are awaiting repeat implantation. CONCLUSION: Sustained improvement or cure of genuine stress incontinence has been achieved using Macroplastique in a large proportion of women with intrinsic sphincter deficiency, often following previous unsuccessful continence surgery. Transurethral ultrasound may prove to be a clinically useful imaging technique for the assessment and subsequent management of treatment failure following Macroplastique implantation.

Stapled versus sutured closure of loop ileostomy: a randomized controlled trial.

OBJECTIVE: To compare the outcome after conventional sutured loop ileostomy closure with stapled ileostomy closure. SUMMARY BACKGROUND DATA: A defunctioning loop ileostomy is now widely used in colorectal surgery. Subsequent closure may be associated with early complications, particularly bowel obstruction. The results of a preliminary nonrandomized study suggested that there was no significant difference in the rate of complications between sutured and stapled closure of loop ileostomy. METHODS: One hundred forty-one consecutive patients who underwent loop ileostomy between 1993 and 1998 were randomized before surgery to either sutured or stapled loop ileostomy closure. Seventy-one patients had stapled closure and 70 had sutured closure. RESULTS: Both groups were comparable in terms of age, sex, original operation, duration after original operation, and level of operating surgeon. Postoperative bowel obstruction occurred in 10/70 (14%) patients after sutured closure compared with 2/71 (3%) patients after stapled closure. Subgroup analysis of ileostomy closure in patients having an ileal pouch showed no significant difference in bowel obstruction between stapled and sutured closure (2/30 vs. 7/29). The incidence of other complications, readmissions, and reoperations did not differ between the two groups. The stapled closure was only 4 minutes quicker than sutured closure. The mean total hospital stay tended to be shorter after the stapled closure than the sutured closure, but this did not reach statistical significance. CONCLUSIONS: Bowel obstruction occurred less frequently after stapled closure, but the mean hospital stay and readmission and reoperation rate did not significantly differ between the two groups.

Long-term results of cutting seton fistulotomy.

BACKGROUND/AIMS: To determine the long term outcome of cutting seton fistulotomy. MATERIALS AND METHOD: An audit of fistula surgery using a cutting seton for cryptoglandular sepsis identified 32 patients treated between 1988-1996. The majority of the patients had a trans-sphincteric (26/32, 81%) fistula. RESULTS: Fourteen (44%) had had previous fistula surgery before seton fistulotomy. Follow up was complete in 28 patients: 8 patients had recurrence (29%), 4 at a new site and 4 at the same site after apparent healing. Major incontinence was reported by 3 patients, minor incontinence by 7 and soiling by 5, but only 7 patients worsened after the cutting seton fistulotomy. Major incontinence was reported only by women who had a previous vaginal delivery. CONCLUSIONS: Cutting setons do not always preserve continence in high trans-sphincteric and complex fistulas. Patients should be warned about a high recurrence rate after cutting seton fistulotomy. The use of a cutting seton for anterior fistulas in female patients with a history of vaginal delivery should be avoided because of the risk of incontinence.

Pharmacodynamics of anticholinergic agents measured by ambulatory urodynamic monitoring: a study of methodology.

The aim of the study was to establish a methodology whereby ambulatory urodynamic monitoring (AUM) may be used in the assessment of the effects of darifenacin on urodynamic measures of detrusor function and symptoms associated with detrusor instability. Six patients (one man and five women) with detrusor instability (DI) on conventional urodynamic monitoring were recruited into this placebo-controlled crossover study. The study was divided into two periods of 7 days of treatment with either darifenacin 5 mg t.d.s. or placebo with the patient crossing over to the alternative treatment after a washout period of 7 days. On the 7th day of each treatment, AUM was carried out. Parameters used to quantify detrusor activity on AUM were the number, amplitude, and duration of detrusor contractions and the total area under the detrusor pressure/time curve. "Events" recorded were urge, leakage episodes, voids, and pain. Six comparable hours of AUM for each treatment period could be analyzed in four patients and 4 hr in one. In three of the five patients, reduction in activity on AUM while on darifenacin was apparent. Symptom data closely matched the changes in detrusor activity measured on AUM. This is the first study reporting the use of AUM in the development of a drug with an effect on detrusor activity. AUM has clear advantages over conventional cystometry, which can only measure surrogate urodynamic parameters at a single time point. The optimal duration of monitoring in this context appears to be 6 hr with prolongation of monitoring time beyond this being unlikely to yield additional useful information. Correlation between symptoms and findings on AUM is good with changes in parameters recorded on AUM relating closely to the improvement in symptoms.
