Abstract
AIM In this study we reviewed our 10-year experience of the medium- to long-term success of sacral nerve stimulation (SNS) for faecal incontinence, with particular reference to the resource implications of running such a service. METHOD All patients treated with permanent SNS implants for faecal incontinence from 2001 to 2012 were identified from a prospective database. The patients underwent follow up at 3 and 6 months, with annual review thereafter. They were divided into four groups: group 1, patients optimized after two reviews; group 2, patients optimized after further review; group 3, patients who failed to reach a satisfactory state; and group 4, patients who had a good initial result with subsequent failure. RESULTS Eighty-five patients underwent permanent SNS with a median follow up of 24 (range: 3-108) months. Group 1 included 30 (35%) patients; group 2 included 27 (32%) patients [median of two (range: 2-6) additional visits]; group 3 included 18 (21%) patients [median of six (range: 3-10) additional visits]; and group 4 included 10 (12%) patients [median interval to failure was 54 (range: 24-84) months]. Twenty-seven per cent of our patients had an unsatisfactory outcome and the cost of follow up for these patients was £36,854 (48.7% of the total follow-up costs). CONCLUSION The study highlights the significant resource implications of running an SNS service with a large proportion of patients requiring prolonged review, with more than one-quarter having an unsatisfactory outcome at a substantial cost.

Abstract
BACKGROUND The effectiveness of rehabilitation programmes are often distorted by the athlete's desire to return and can result in injury recurrence. Athletic assessments allow for objective and reliable measurements to track rehabilitation progress. This case study used a multi-component assessment strategy to assess a rugby player's lower-extremity strength and symmetry as a primary determinate of their return-to-sport status. CASE DESCRIPTION A professional rugby league player was assessed for lower-extremity isokinetic strength and sprint kinetics pre- and 10-weeks post-rehabilitation programme following two consecutive knee injuries involving surgical intervention. OUTCOMES Pre-testing analysis showed clinical and functional strength deficits in the injured leg as high as 34% compared to the non-injured leg. Pre- to post-testing showed: increases in peak torque (49%) and decreased asymmetries by 50%; unilateral horizontal force increased (injured: 50%, non-injured: 19%) during sprinting; force production asymmetries decreased up to 18%. DISCUSSION The rugby player showed clinical and functional strength deficiencies return to normal ranges following a rehabilitation programme. A return-to-sport decision was made by the athlete's supporting health team based on the sizeable asymmetry decreases and return-to-normative ranges for knee and hip strength and sprint kinetics. The athlete returned to the 2013 National Rugby League season without any major injuries.

Abstract
AIM Many women undergoing sacral neuromodulation for faecal incontinence have coexisting pelvic floor dysfunction. We used a global pelvic-floor assessment questionnaire to evaluate the effect of sacral neuromodulation on non-bowel related symptomatology. METHOD The electronic Personnel Assessment Questionnaire - Pelvic Floor (ePAQ-PF) is a validated Web-based electronic pelvic floor questionnaire. Women with faecal incontinence underwent assessment using the ePAQ. Pre- and poststimulator data were analysed over a 4.5-year period. RESULTS Forty-three women (mean age 56.5 years; median follow up 6.8 months) were included. All (100%) had urinary symptoms, 81.4% had vaginal symptoms and 85.7% described some sexual dysfunction. There was a significant improvement in faecal incontinence and in bowel-related quality of life (P < 0.005) as well as in irritable bowel syndrome (IBS)-related symptoms (P < 0.01) and in bowel-related sexual heath (P < 0.01). Symptoms of vaginal prolapse significantly improved (P = 0.05). There was also improvement in symptoms of overactive bladder (P = 0.005) and in urinary-related quality of life (P < 0.05). A global health improvement was reported in 58.1%, mainly in bowel evacuation (P < 0.01) and in vaginal pain and sensation (P < 0.05). In sexually active female patients, significant improvements in vaginal and bowel-related sexual health were seen (P < 0.005). Improvement in general sex life following stimulation was reported in 53.3%. CONCLUSION A Web-based electronic pelvic-floor assessment questionnaire has demonstrated global improvement in pelvic floor function in bowel, urinary, vaginal and sexual dimensions in women following sacral neuromodulation for faecal incontinence.

Abstract
BACKGROUND Prucalopride is a selective serotonin receptor agonist with prokinetic activity, indicated for women with chronic constipation in whom laxatives have failed to provide adequate relief. Data suggests an improvement in about 50 % of such patients but whether the therapeutic effect is on patients with slow transit constipation (STC) and/or obstructed defaecation syndrome (ODS), or even those with constipation-predominant irritable bowel syndrome (IBS-C) is unknown. We therefore assessed whether there is any association between prucalopride efficacy and constipation type. METHODS All patients receiving prucalopride between June 2010 and April 2012 at our institution were identified, and data analysed following a 4-week "test" period. Patients were sub-grouped as those suffering with ODS, STC, mixed (ODS and STC) or IBS-C based on symptomatology and investigations. Subjective assessment of patient satisfaction and continuation of medication were taken as positive outcomes and analysed for each sub-type along with any side effects. RESULTS Sixty-nine patients met our criteria. Data were available for 59 women (median age 46 years, range 17-79 years). Sixty-five per cent of prescriptions came from colorectal surgeons. Overall, 25 out of 59 (42 %) patients improved, according to our criteria, after the 4-week trial period. Seventeen patients (29 %) had ODS, 26 (44 %) had STC, 7 (12 %) had mixed symptoms and 9 (15 %) had IBS-C. At 4 weeks, 10 out of 17 patients (59 %) with ODS had improved compared with 4 out of 9 patients (44 %) with IBS-C, 3 out of 7 patients (43 %) with mixed symptoms and 8 out of 26 (31 %) patients with STC. The underlying disorder did not predict whether or not a patient responded to the 4-week trial period (p = 0.32). Nine patients (15 %) experienced side effects that precluded further use. CONCLUSIONS Patients with all categories of constipation may respond to prucalopride. A trial regime may be indicated regardless of the aetiology of the constipation.

Abstract
OBJECTIVE To examine changes in breast cancer knowledge, attitudes, beliefs and behaviors following implementation of a tribal run CDC Breast and Cervical Cancer Program (BCCP), we report 2006 survey results from Hopi women and contrast findings with 1993 survey data and BCCP reports. METHODS Community meetings, focus groups, and researchers jointly developed a culturally appropriate survey instrument. Hopi women randomly selected from Tribal enrollment lists were interviewed in-person by Hopi interviewers; 250 women ≥ age 18 participated (87% response) between June and December, 2006. RESULTS Among women 40+, 77.5% reported ever having had a mammogram and 68.9% reported having done so within the past 2years, an increase from 45.2% and 46% self-reported in 1993. Compared to 1993, more women in 2006 (88.1% vs. 59%) believed that a mammogram can detect cancer and more than 90% now believe that early detection of cancer can save lives. Women reported a preference (60%) for receiving health care at the Hopi BCCP. Survey results were validated using programmatic data which estimated 76.6% of Hopi women had received mammography screening. CONCLUSION Implementation of a tribal run BCCP has resulted in a substantial increase in mammography screening on the Hopi reservation.

Abstract
AIM The objective of the study was to assess safety, efficacy and outcomes of stapled transanal rectal resection (STARR) procedure for obstructed defaecation syndrome (ODS) with two stapling devices, PPH01 and Trans-STARR. METHOD Data were collected on all patients undergoing PPH01 or Trans-STARR over a 2 year period. Initially, all were treated using the PPH01 device and during the last 8 months using the Trans-STARR. RESULTS During the analysis period, 25 consecutive patients were treated with PPH01 and 27 patients were treated with Trans-STARR. The median follow up was 12 months (range 3-12 months) for the PPH01 group and 6 months (range 3-12 months) for the Trans-STARR group. Although the resected specimen was larger in the Trans-STARR group (P < 0.001), there was no difference in early adverse events, time to discharge or late complications between the groups. In both groups, postoperative urgency was common (occurring more than occasionally in up to 40% at last review) but the incidence was high preoperatively. ODS and symptom severity scores improved with surgery (P < 0.001). However, the degree of improvement was similar with complete resolution of symptoms occurring in 64% of the PPH01 group and 67% of the Trans-STARR group. CONCLUSION Our study shows that both procedures are safe and effective in the surgical treatment of obstructed defaecation but despite a larger resection the Trans-STARR procedure does not offer any additional benefit. A policy of individualizing techniques tailored to the extent of prolapse may be appropriate, but requires further evaluation.

Abstract
BACKGROUND Bochdalek hernias are a very rare form of diaphragmatic hernias. There are no robust studies that reveal the true natural history of this disease process. The aim of this study was to summarize clinically relevant data for the purpose of assisting surgeons with the work-up, diagnosis, and treatment of adult patients with Bochdalek hernia. METHODS A literature search was performed using PubMed, Google scholar, EMBASE and the following keywords: Bochdalek hernia, congenital diaphragmatic hernia, and posterolateral hernia. All case reports and series after 1955 that pertained to adults were included in the review. The following data points were queried: age, sex, presentation, studies utilized during work-up, laterality, surgical approach, hernia sac management, specific minimally invasive surgical techniques, and follow-up. RESULTS A total of 124 articles comprising 173 patients met the inclusion criteria. Based on the data provided, several conclusions regarding this disease process can be made. Most patients present with symptoms related to their hernia (86%). Pain is the most common complaint (69%). While laparotomy is the most widely used surgical approach (38%), minimally invasive surgical techniques have gained popularity since their first report in 1995. Laparoscopic repair can be performed with a low complication rate (7%) and short hospital stay (4 days). CONCLUSIONS Using modern surgical techniques to include laparoscopy, repair can be performed safely, with a short hospital stay, and with minimal morbidity or mortality.

Abstract
OBJECTIVES To determine whether the addition of magnetic resonance imaging (MRI) to current patient evaluation by triple assessment would aid tumour localisation within the breast and thus reduce the reoperation rate in women with primary breast tumours who are scheduled for wide local excision (WLE), and to assess whether the addition of MRI would be cost-effective for the UK NHS. DESIGN A multicentre, randomised controlled, open, parallel group trial with equal randomisation. The main design was supplemented with a qualitative study to assess patients' experiences of the treatment process and care pathway, and involved the development of a non-scheduled standardised interview (NSSI). SETTING The study took place at 45 hospitals throughout the UK. PARTICIPANTS Women aged 18 years or over with biopsy-proven primary breast cancer who had undergone triple assessment, were scheduled for WLE, and were capable of providing written informed consent. INTERVENTIONS Patients were randomised to receive MRI or no MR1. Randomisation was performed using minimisation, incorporating a random element. All MRI was performed at 1.5 T or 1.0 T with a dedicated bilateral breast coil. MAIN OUTCOME MEASURES The primary end point of the trial was the reoperation rate. Secondary outcome measures included discrepancies between imaging and histopathology, and the effectiveness of using both procedures; change in clinical management after using MRI; the clinical significance of MRI-only-detected lesions; the rate of interventions; the ipsilateral tumour recurrence rate; patient quality of life (QoL); and cost-effectiveness. RESULTS From a total of 1623 patients, 816 were randomised to MRI and 807 to no MRI. No differences in reoperation rates were found between the two groups of patients [MRI patients 18.75%, no MRI 19.33%, difference 0.58%, 95% confidence interval (CI) -3.24 to 4.40]. Therefore, the addition of MRI to conventional triple assessment was not found to be statistically significantly associated with a reduced reoperation rate (odds ratio = 0.96, 95% CI 0.75-1.24, p = 0.7691). The best agreement between all imaging modalities and histopathology with regard to tumour size and extent of disease was found in patients over 50 years old with ductal tumours NST and who were node negative. In the imaging arm, mastectomy was found to be pathologically avoidable for 16 (27.6%) out of 58 patients who underwent the procedure. There were no significant differences between the groups regarding the proportion of patients receiving chemotherapy, radiotherapy or additional adjuvant therapies, as well as for local recurrence-free interval rates and QoL. An acceptable NSSI was developed for use in this population of patients. Economic analysis found no difference in outcomes between the two trial arms. CONCLUSIONS The addition of MRI to triple assessment did not result in a reduction in operation rates, and the use of MRI would thus consume extra resource with few or no benefits in terms of cost-effectiveness or HRQoL. However, MRI showed potential to improve tumour localisation, and preoperative biopsy of MRI-only-detected lesions is likely to minimise the incidence of inappropriate mastectomy.

Abstract
OBJECTIVE It has recently been reported that up to one-third of patients with nonmetastatic distal rectal cancer managed with neoadjuvant chemoradiation therapy (CRT) had a complete clinical response (cCR) to treatment. In the selected cases, this has been used as the sole treatment. The aim of this study was to determine the frequency of complete pathological response for patients receiving CRT in one centre in the UK. METHOD Patients receiving 6 weeks of neoadjuvant CRT were identified using the two cancer audit databases in two different tertiary hospitals from January 2002 to November 2007. Pathology was reviewed and the histopathological response of the resected specimen to CRT was evaluated using the Mandard classification (1 = complete response, 5 = no response) RESULTS One hundred and thirty-two consecutive patients [median age 61 (range 44-86) years, 90 men] with nonmetastatic locally advanced rectal cancer received neoadjuvant chemo radiotherapy between 2002 and 2007 followed by resection of the tumour. Data were available from 129 patients. CONCLUSION Only 13 out of 132 (10%) of patients had a complete pathological response. This is one-third of the cCR previously reported. Nonsurgical therapy for rectal cancer using the Habr-Gama treatment algorithm may only be effective in a very small proportion of patients with rectal cancer in the UK and nonoperative treatment would not be recommended.

Abstract
BACKGROUND This study investigated adhesive intestinal obstruction (AIO) and incisional hernia (IH) in patients undergoing laparoscopically assisted and open surgery for colorectal cancer. METHODS In a case-note review of patients randomized to the Medical Research Council's Conventional versus Laparoscopic-Assisted Surgery In Colorectal Cancer (CLASICC) trial, primary and key secondary endpoints were AIO and IH admission rates respectively. RESULTS Of 411 patients, 11 were admitted for AIO: four (3.1 per cent) of 131 patients in the open arm of the trial versus seven (2.5 per cent) of 280 in the laparoscopic arm (difference 0.6 (95 per cent confidence interval (c.i.) - 2.9 to 4.0) per cent). Thirty-six patients developed IH: 12 (9.2 per cent) after open versus 24 (8.6 per cent) after laparoscopic surgery (difference 0.6 (95 per cent c.i. - 5.3 to 6.5) per cent). Results by actual procedure showed higher AIO and IH rates in the 24.5 per cent of patients who converted from laparoscopic to open surgery (AIO: 2.3, 2.0 and 6 per cent; IH: 8.6, 7.4 and 11 per cent-for open, laparoscopic and converted operations respectively). CONCLUSION Although this study has not confirmed that laparoscopic surgery reduces rates of AIO and IH after colorectal cancer surgery, trends suggest that a reduction in conversion to open surgery and elimination of port-site hernias may produce such an effect.

Abstract
OBJECTIVE A prospective technical feasibility study of cap assisted ESD for 'curative intent' in patients with residual or local neoplastic recurrence following EMR. Primary end points were second stage R0 resection rate, safety and recurrence. METHOD Salvage ESD was performed using the Olympus GIF-XQ240 gastroscope and KD-630L insulation tipped knife. Thirty-day mortality, re-admission rates, complications and histological resection status were collected prospectively up to 9 months following index resection. RESULTS Thirty patients met eligibility criteria. Index R0 resection was achieved in 25/30 (83%) lesions. One patient underwent surgical excision with a second receiving a curative second stage dissection. Ninety-six per cent (29/30) patients were discharged within 24 h of the procedure with a 0% 30-day mortality and re-admission rate. Bleeding occurred in 5/30 (16%) treated successfully with endoluminal haemostasis. There were no perforations. Overall 'cure' rates at short-term follow-up [median 6/12 (range; 3-18)] was 96%. CONCLUSION This novel application of ESD for first line 'salvage' therapy in treating residual or locally recurrent neoplastic disease may be a safe, minimally invasive and cost effective alternative to direct surgical resection in a select patient cohort.

Abstract
Recently, miniaturization of a novel confocal laser endomicroscope (Optiscan Pty, Notting Hill, Victoria, Australia) has permitted functional integration into the distal tip of a conventional video colonoscope (Pentax EC3870K; Pentax, Tokyo, Japan) enabling imaging of the surface epithelium and the underlying lamina propria during ongoing video endoscopy. Using endomicroscopy and intravenous sodium fluorescein as a contrast agent, 'virtual histology' can be created, which allows visualization of both the surface epithelium, and some of the lamina propria (down to a quarter of a millimetre), including the microvasculature. Confocal endomicroscopy may have major implications in the future of colonoscopy as uniquely it allows in vivo diagnosis of colonic intraepithelial neoplasia and carcinoma enabling 'smart' biopsy targeting and hence potentially influencing 'on table' management decisions. Initial pilot data have now shown that confocal imaging in vivo using the newly developed EC3870K has high overall accuracy for the immediate diagnosis of intraepithelial neoplasia and carcinoma in sporadic screened cohorts, but also has a role in the detection of intraepithelial neoplasia detection in chronic ulcerative colitis cancer screening when used in conjunction with methylene blue chromoscopy. We discuss the current evidence in support of confocal endomicroscopy in the colorectum and explore the new diagnostic possibilities for this technology.

Abstract
BACKGROUND AND AIMS Loss of mucosal 'lift' prior to submucosal dissection or endoscopic mucosal resection (EMR) increases the risk of complications. We conducted a randomized controlled trial comparing dextrose solution with sodium hyaluronic acid (SHA) for the EN BLOC resection of Paris type I/0-II and lateral spreading lesions of the colorectum. PATIENTS AND METHODS Patients with Paris type I/0-II or lateral spreading tumor lesions of < 30 mm were randomized in a 1 : 1 ratio to undergo EMR using either dextrose solution or SHA. The primary study outcome was complete resection. Secondary outcomes were endoscopic complications (i. e. perforation or bleeding) and polyp recurrence rates. RESULTS A total of 174 patients were randomized. R0 resection was achieved in 59 of the 82 lesions (72 %) in the dextrose group and 56 of the 81 lesions (69 %) in the SHA group ( P > 0.1), with no significant difference in median lesion diameter ( P > 0.1). The median number of post resection surveillance colonoscopies was 3 (range 2 - 7) in the dextrose group and 4 (range 2 - 6) in the SHA group ( P = NS). The median post index EMR resection follow-up period was 20 months (range 4 - 26) in the DS group and 18 months (range 3 - 22) in the SHA group ( P = NS). Recurrence rates were 1/82 (1.21 %) in the dextrose group and 1/81 (1.23 %) in the SHA group ( P = NS). CONCLUSIONS EMR using dextrose solution is as effective as SHA in terms of resection completion, recurrence rates, and complications.

Abstract
The effect of breast cancer surgery timing during the menstrual cycle on prognosis remains controversial. We conducted a multicentre prospective study to establish whether timing of interventions influences prognosis. We report 3-year overall and disease-free survival (OS/DFS) results for ‘primary analysis’ patients (regular cycles, no oral contraceptives within previous 6 months). Data were collected regarding timing of interventions in relation to patients’ last menstrual period (LMP) and first menstrual period after surgery (FMP). Hormone profiles were also measured. Cox's proportional hazards model incorporated LMP in continuous form. Exploratory analyses used menstrual cycle categorisations of Senie, Badwe and Hrushesky. Hormone profiles with LMP and FMP data were also used to define menstrual cycle phase. Four hundred and twelve ‘primary analysis’ patients were recruited. Three-year OS from first surgery was 90.7, 95% confidence interval (CI) [87.9, 93.6%]. Menstrual cycle according to LMP was not statistically significant (OS: hazard ratio (HR)=1.02, 95%CI [0.995,1.042], P=0.14; DFS: HR=1.00, 95%CI [0.980,1.022], P=0.92). Timing of surgery in relation to menstrual cycle phase had no significant impact on 3-year survival. This may be due to 97% of patients receiving some form of adjuvant therapy. Survival curves to 10 years indicate results may remain true for longer-term survival.

Abstract
BACKGROUND Although conventional colonoscopy is the most sensitive test available for the investigation of the colorectum for polyps, there are data that raise concerns about its sensitivity. Chromoscopy may be one way of enhancing the ability for colonoscopy to detect polyps particularly diminutive flat lesions that may be otherwise difficult to detect. OBJECTIVES To determine whether the use of chromoscopy enhances detection of polyps and neoplasia during endoscopic examination of the colon and rectum. SEARCH STRATEGY MEDLINE, EMBASE and the Cochrane Library databases were searched along with a hand search of abstracts from relevant meetings. Search terms included randomised trials containing combinations of the following: 'chromoscopy' 'colonoscopy' 'dye-spray' 'chromo-endoscopy' 'indigo-carmine' 'magnifying endoscopy'. SELECTION CRITERIA All prospective randomised trials comparing chromoscopic with conventional endoscopic examination of the lower gastrointestinal tract were included. Patients with inflammatory bowel disease or polyposis syndromes were excluded. DATA COLLECTION AND ANALYSIS Three reviewers assessed the methodological quality of potentially eligible trials and independently extracted data from the included trials. Outcome measures included the detection of polyps (neoplastic and non-neoplastic), the detection of diminutive lesions, the number of patients with multiple neoplastic lesions and the extubation time. MAIN RESULTS Four trials were include that met the inclusion criteria and although there were some methodological drawbacks and differences in study design, combining the results showed a significant difference in favour of chromoscopy for all detection outcomes. In particular, chromoscopy is likely to yield significantly more patients with at least one neoplastic lesion (OR 1.61 (CI 1.24-2.09)) and significantly more patients with three or more neoplastic lesions (OR 2.55 (CI 1.49-4.36)). Not surprisingly the withdrawal times were significantly slower for the chromoscopy group. AUTHORS' CONCLUSIONS There appears to be strong evidence that chromoscopy enhances the detection of neoplasia in the colon and rectum. Patients with neoplastic polyps, particularly those with multiple polyps, are at increased risk of developing colorectal cancer. Such lesions, which presumably would be missed with conventional colonoscopy, could contribute to the interval cancer numbers on any surveillance programme.

Abstract
BACKGROUND Faecal incontinence is a debilitating problem with significant medical, social and economic implications. Treatment options include conservative, non-surgical interventions (e.g. pelvic floor muscle training, biofeedback, drugs, sacral nerve stimulation) and surgical procedures. A surgical procedure may be aimed at correcting an obvious mechanical defect, or augmenting a functionally deficient but structurally intact sphincter complex or replace an absent/non-functioning sphincter. OBJECTIVES To assess the effects of surgical techniques for the treatment of faecal incontinence in adults who do not have rectal prolapse. Our aim was firstly to compare surgical management with non-surgical management and secondly, to compare the various surgical techniques. SEARCH STRATEGY We searched the Cochrane Incontinence Group Specialised Trials Register (31 January 2006), the Cochrane Colorectal Cancer Group trials register (31 January 2006), the Cochrane Central Register of Controlled Trials (2006, Issue 1), PubMed (1 January 1950 to 31 January 2006) and EMBASE (1 January 1998 to 31 January 2006) were undertaken. The British Journal of Surgery (January 1995 to May 2006) Colorectal Diseases (January 2000-May 2006) and the Diseases of the Colon and Rectum (January 1995 to May 2006) were specifically handsearched. The proceedings of the Association of Coloproctology meeting held from 1999 to 2006 were perused. Reference lists of all relevant articles were searched for further trials. SELECTION CRITERIA All randomised or quasi-randomised trials of surgery in the management of adult faecal incontinence (other than surgery for rectal prolapse). DATA COLLECTION AND ANALYSIS Two reviewers independently selected studies from the literature searches, assessed the methodological quality of eligible trials and extracted data. The three primary outcome measures were: change or deterioration in incontinence, failure to achieve full continence, and the presence of faecal urgency. MAIN RESULTS Nine trials were included with a total sample size of 264 participants. Two trials included a group managed non-surgically. One trial compared levatorplasty with anal plug stimulation, one compared artificial bowel sphincter with best supportive care; numbers were small in both trials. The artificial bowel sphincter insertion was followed by significant improvements in at least one primary outcome but with high rates of significant morbidity. Seven studies compared different surgical interventions. These included anterior levatorplasty versus postanal repair, anterior levatorplasty versus total pelvic floor repair, total pelvic floor versus postanal repair, end to end versus overlap sphincter repair, overlap repair with or without a defunctioning stoma or with or without biofeedback, total pelvic floor repair versus repair plus internal sphincter plication and neosphincter formation versus total pelvic floor repair. Only one comparison had more that one trial (total pelvic floor versus postanal repair-44 participants) and no comparison showed any statistically significant difference in primary outcome measures, with wide confidence intervals. AUTHORS' CONCLUSIONS Despite more studies being included in this update, the continued small number of relevant trials identified together with their small sample sizes and other methodological weaknesses continue to limit the usefulness of this review for guiding practice. It was impossible to identify or refute clinically important differences between the alternative surgical procedures. Larger rigorous trials are still needed. However, it should be recognised that the optimal treatment regime may be a complex combination of various surgical and non-surgical therapies.
