Abstract
Abstract
Introduction
Acute lower gastrointestinal haemorrhage can potentially be life-threatening. We present a case of a massive rectal bleed which was managed successfully with a balloon tamponade device designed for upper gastrointestinal haemorrhage.
Presentation of case
A 75-year-old gentleman, with a history of human immunodeficiency virus and cirrhosis with portal hypertension, presented with bright red rectal bleeding. Investigations showed a low haemoglobin level (74 g/L) and deranged clotting. Oesophago-gastro-duodenoscopy demonstrated no fresh or altered blood. Flexible sigmoidoscopy revealed active bleeding from a varix within the anterior rectal wall 4 cm from the anal verge. Efforts to stop the bleeding, including endoscopic clips, adrenaline injection and rectal packing, were unsuccessful and the patient became haemodynamically unstable. A Sengstaken-Blakemore tube was inserted per rectum and the gastric balloon was inflated to tamponade the lower rectum. The oesophageal balloon was then inflated to hold the gastric balloon firmly in place. A computed tomography angiogram demonstrated no evidence of haemorrhage with balloon tamponade. After 36 h, the balloon was removed with no further episodes of bleeding.
Discussion
The application of a balloon tamponade device should be considered in the management algorithm for acute lower gastrointestinal bleed. Advantages include its rapid insertion, immediate results and ability to measure further bleeding after the catheter has been placed.
Conclusions
Sengstaken-Blakemore tube per rectum may effectively control massive low rectal bleeding when alternative methods have been unsuccessful.

Abstract
Abstract
Aim
Colorectal multi-disciplinary teams (CR MDTs) were introduced to enhance the cancer care pathway and allow for early investigation and treatment of colorectal cancer. However, there are no gold standards set for this process. The aim of this study is to establish recommendations on the principles, organisation, structure and output of CR MDTs internationally.
Method
The available literature on the role of CR MDTs from January 1999 and March 2020 in the United Kingdom (UK), United States of America (USA) and continental Europe was evaluated. Historical background, structure, core members, education, frequency, patient selection criteria, quality assurance, output and outcomes were extracted from data from the UK, USA, and continental Europe.
Results
Fifty studies were identified that specifically met the inclusion criteria. CR MDTs should occur at least once a month with established key members. Generally, all colorectal cancer patients should be discussed and there should be a focus on education. There are noted differences in the lead member of the CR MDT, the use of information technology and storage of MDT information in databases and quality assurance internationally.
Conclusions
The most common issues facing MDTs internationally include a lack of staffing and resources as well as limited information on the patient’s fitness and preference for surgery. These factors are important and urgent improvements are required in these areas in CR MDTs. Quality assurance should be a mandatory component of every CR MDT.

Abstract
Background Anal squamous cell carcinoma (ASCC) is an uncommon cancer associated with human immunodeficiency virus (HIV) infection. There has been increasing interest in providing organ-sparing treatment in small node-negative ASCC’s, however, there is a paucity of evidence about the use of local excision alone in people living with HIV (PLWH). The aim of this study was to evaluate the efficacy of local excision alone in this patient population. Methods We present a case series of stage 1 and stage 2 ASCC in PLWH and HIV negative patients. Data were extracted from a 20-year retrospective cohort study analysing the treatment and outcomes of patients with primary ASCC in a cohort with a high prevalence of HIV. Results Ninety-four patients were included in the analysis. Fifty-seven (61%) were PLWH. Thirty-five (37%) patients received local excision alone as treatment for ASCC, they were more likely to be younger (p = 0.037, ANOVA) and have either foci of malignancy or well-differentiated tumours on histology (p = 0.002, Fisher’s exact test). There was no statistically significant difference in 5-year disease-free survival and recurrence between treatment groups, however, patients who had local excision alone and PLWH were both more likely to recur later compared to patients who received other treatments for ASCC. (72.3 months vs 27.3 months, p = 0.06, ANOVA, and 72.3 months vs 31.8 months, p = 0.035, ANOVA, respectively). Conclusions We recommend that local excision be considered the sole treatment for stage 1 node-negative tumours that have clear margins and advantageous histology regardless of HIV status. However, PLWH who have local excision alone must have access to an expert long-term surveillance programme after treatment to identify late recurrences.

Abstract
Background Classification of pelvic local recurrence (LR) after surgery for primary rectal cancer is not currently standardized and optimal imaging is required to categorize anatomical site and plan treatment in patients with LR. The aim of this review was to evaluate the systems used to classify locally recurrent rectal cancer (LRRC) and the relevant published outcomes. Methods A systematic review of the literature prior to April 2020 was performed through electronic searches of the Science Citation Index Expanded, EMBASE, MEDLINE and CENTRAL databases. The primary outcome was to review the classifications currently in use; the secondary outcome was the extraction of relevant information provided by these classification systems including prognosis, anatomy and prediction of R0 after surgery. Results A total of 21 out of 58 eligible studies, classifying LR in 2086 patients, were reviewed. Studies used at least one of the following eight classification systems proposed by institutions or institutional groups (Mayo Clinic, Memorial Sloan-Kettering – original and modified, Royal Marsden and Leeds) or authors (Yamada, Hruby and Kusters). Negative survival outcomes were associated with increased pelvic fixity, associated symptoms of LR, lateral compared with central LR and involvement of three or more pelvic compartments. A total of seven studies used MRI with specifically defined anatomical compartments to classify LR. Conclusion This review highlights the various imaging systems in use to classify LRRC and some of the prognostic indicators for survival and oncological clearance based on these systems. Implementation of an agreed classification system to document pelvic LR consistently should provide more detailed information on anatomical site of recurrence, burden of disease and standards for comparative outcome assessment.

Abstract
AIM Continuity of the mesentery has recently been established and may provide an anatomical basis for optimal colorectal resectional surgery. Preliminary data from operative specimen measurements suggest there is a tapering in the mesentery of the distal sigmoid. A mesenteric waist in this area may be a risk factor for local recurrence of colorectal cancer. This study aimed to investigate the anatomical characteristics of the mesentery at the colorectal junction. METHOD In this cross-sectional study, 20 patients were recruited. After planned colorectal resection, the surgical specimens were scanned in a MRI system and subsequently dissected and photographed as per national pathology guidelines. Mesenteric surface area and linear measurements were compared between MRI and pathology to establish the presence and location of a mesenteric waist. RESULTS Specimen analysis confirmed that a narrowing in the mesenteric surface area was consistently apparent at the rectosigmoid junction. Above the anterior peritoneal reflection, the surface area and posterior distance of the mesentery of the upper rectum initially decreased before increasing as the mesentery of the sigmoid colon. These anatomical properties created the appearance of a mesenteric 'waist' at the rectosigmoid junction. Using the anterior reflection as a reference landmark, the rectosigmoid waist occurred at a mean height of 23.6 and 21.7 mm on MRI and pathology, respectively. CONCLUSION A rectosigmoid waist occurs at the junction of the mesorectum and mesocolon, and is a mesenteric landmark for the rectum that is present on both radiology and pathology.

Abstract
AIM Robotic techniques are being increasingly used in colorectal surgery. There is, however, a lack of training opportunities and structured training programmes. Robotic surgery has specific problems and challenges for trainers and trainees. Ergonomics, specific skills and user-machine interfaces are different from those in traditional laparoscopic surgery. The aim of this study was to establish expert consensus on the requirements for a robotic train-the-trainer curriculum amongst robotic surgeons and trainers. METHOD This is a modified Delphi-type study involving 14 experts in robotic surgery teaching. A reiterating 19-item questionnaire was sent out to the same group and agreement levels analysed. A consensus of 0.8 or higher was considered to be high-level agreement. RESULTS Response rates were 93-100% and most items reached high levels of agreement within three rounds. Specific requirements for a robotic faculty development curriculum included maximizing dual-console teaching, theatre team training, nontechnical skills training, patient safety, user-machine interface training and telementoring. CONCLUSION A clear need for the development of a train-the-trainer curriculum has been identified. Further research is needed to assess feasibility, effectiveness and clinical impact of a robotic train-the-trainer curriculum.

Abstract
BACKGROUND There are many options and little guiding evidence when choosing suture types with which to close the abdominal wall fascia. This network meta-analysis investigated the effect of suture materials on surgical site infection, hernia, wound dehiscence and sinus/fistula occurrence after abdominal surgery. The aim was to provide clarity on whether previous recommendations on suture choice could be followed with confidence. METHODS AND METHODS In February 2017, the Cochrane Central Register of Controlled Trials, Medline, EMBASE and Science Citation Index Expanded were searched for randomised controlled trials investigating the effect of suture choice on these four complications in closing the abdomen. A reference search of identified trials was performed. Prisma guidelines and the Cochrane risk of bias tool were followed in the data extraction and synthesis. Two review authors screened titles and abstracts of trials identified. A random effect model was used for the surgical site infection network based on the deviance information criterion statistics. RESULTS Thirty-one trials were included (11,533 participants). No suture material reached the predetermined 90% probability threshold for determination of 'best treatment' for any outcome. Pairwise comparisons largely showed no differences between suture types for all outcomes measured. However, nylon demonstrated a reduction in the occurrence of incisional hernias with respect to two commonly used absorbable sutures: polyglycolic acid (odds ratio, OR 1.91; 95% confidence interval, CI, 1.01-3.63) and polyglyconate (OR 2.18; 95% CI 1.17-4.07). CONCLUSIONS No suture type can be considered the 'best treatment' for the prevention of surgical site infection, hernia, wound dehiscence and sinus/fistula occurrence.

Abstract
AIM This study aimed to assess the reliability of measurements and bony landmarks for the rectosigmoid junction on MRI. METHOD The staging MRI scans for 100 patients were reviewed. The junction of the mesorectum and mesocolon was used to identify the rectum and sigmoid. The performance of current metric measurements or bony landmarks was then compared against the actual anatomical bowel segment. RESULTS The mean distance of the sigmoid take-off from the anal verge was 12.6 cm (SD 1.8 cm, range 9.4-19.0 cm). At a cutoff of 12 cm, the anatomical bowel segment was found to be sigmoid colon rather than rectum in 35% of patients. At 15 and 16 cm the bowel segment was sigmoid in 84% and 96% of patients, respectively. At the sacral promontory and the third sacral segment, the bowel segment was sigmoid in 28% and 100% of patients, respectively. CONCLUSION Current definitions of the rectum that rely on arbitrary measurements or bony landmarks will not locate the correct point of transition between the rectum and sigmoid in the majority of patients. The sigmoid take-off offers an alternative, anatomically bespoke, landmark.

Abstract
Introduction This study aimed to ascertain whether missed obstetric anal sphincter injury at delivery had worse functional and quality of life outcomes than primary repair immediately following delivery. Materials and methods Two to one propensity matching was undertaken of patients presenting to a tertiary pelvic floor unit with ultrasound evidence of missed obstetric anal sphincter injury within 24 months of delivery with patients who underwent primary repair at the time of delivery by parity, grade of injury and time to assessment. Outcomes compared included Birmingham Bowel, Bladder and Urinary Symptom Questionnaire (BBUSQ), Wexner Incontinence Score, Short Form-36, Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire and anorectal physiology results. Results Thirty-two missed anal sphincter injuries were matched two to one with sixty-two patients who underwent primary repair of an anal sphincter defect. Mean time to follow-up was 9.31 ± 6.79 months. Patients with a missed anal sphincter injury had suffered more incontinence, as seen in higher the Birmingham Bowel, Bladder and Urinary Symptom Questionnaire (BBUSQ; 30.56% ± 14.41% vs. 19.75% ± 15.65%, P = 0.002) and Wexner scores (6.00 ± 3.76 vs. 3.67 ± 4.06, P = 0.009). They also had a worse BBUSQ urinary domain score (28.25% ± 14.9% vs. 17.01 ± 13.87%, P = 0.001) and worse physical functioning as measured by the Short Form-36 questionnaire (P = 0.045). There were no differences in other outcomes compared, including anorectal physiology and sexual function. Discussion In the short-term, patients with a missed obstetric anal sphincter injury had significantly worse faecal incontinence and urinary function scores, however quality of life and sexual function were largely comparable between groups. Conclusions Longer-term follow-up is needed to assess the effects of missed obstetric anal sphincter injury over time.

Abstract
Faecal incontinence is a common complication of ileal pouch anal anastomosis (IPAA) and seems to worsen with time. The aim of this paper is to review the evidence of the use of sacral nerve stimulation (SNS) for patients with faecal incontinence after IPAA. A literature search was performed on PubMed and Cochrane databases for all relevant articles. All studies, which reported the outcome of SNS in patients with faecal incontinence after IPAA, were reviewed. Three papers were identified, including a case report, cohort study and retrospective study. The total number of patients was 12. The follow-up duration included 3 months, 6 months and 24 months. After peripheral nerve evaluation, definitive implantation was performed in 10 (83.3%) patients. All three studies reported positive outcomes, with CCF scores and incontinence episodes improving significantly. Preliminary results suggest good outcome after permanent SNS implant. Studies with larger sample sizes, well-defined patient characteristics and standardized outcome measures are required to fully investigate the effect of SNS in IPAA patients.

Abstract
AIM MRI-detected extramural venous invasion (mrEMVI) is a poor prognostic factor in rectal cancer. Preoperative chemoradiotherapy (CRT) can cause regression in the severity of EMVI and subsequently improve survival whereas mrEMVI persisting after CRT confers an increased risk of recurrence. The effect of adjuvant chemotherapy (AC) following CRT on survival in rectal cancer remains unclear. The aim of this study was to determine whether there is a survival advantage for AC given to patients with mrEMVI persisting after CRT. METHOD A prospective analysis was conducted of consecutive patients with locally advanced rectal cancer between 2006 and 2013. All patients underwent CRT followed by surgery. AC was given to selected patients based on the presence of specific 'high-risk' features. Comparison was made between patients offered AC with observation alone. The primary outcome was 3-year disease-free survival (DFS). RESULTS Of 631 patients, 227 (36.0%) demonstrated persistent mrEMVI following CRT. Patients were grouped on the basis of AC or observation and were matched for age, performance status and final histopathological staging. Three-year DFS in the AC group was 74.6% compared with 53.7% in the observation only group. AC had a survival benefit on multivariate analysis (hazard ratio 0.458; 95% CI: 0.271-0.775, P = 0.004). CONCLUSION Patients with persistent mrEMVI following CRT who receive AC may have a decreased risk of recurrence and an improved 3-year DFS compared with patients not receiving AC, irrespective of age and performance status.

Abstract
AIM There is wide disparity in the care of patients with multivisceral involvement of rectal cancer. The results are presented of treatment of advanced and recurrent colorectal cancer from a centre where a dedicated multidisciplinary team (MDT) is central to the management. METHOD All consecutive MDT referrals between 2010 and 2014 were examined. Analysis was undertaken of the referral pathway, site, selection process, management decision, R0 resection rate, mortality/morbidity/Clavien-Dindo (CD) classification of morbidity, length of stay (LOS) and improvement of quality of life. RESULTS There were 954 referrals. These included locally advanced primary rectal cancer (LAPRC b-TME) (39.0%), rectal recurrence (RR) (22.0%), locally advanced primary colon cancer (LAPCC T3c/d-T4) (21.1%), colon cancer recurrence (CR) (12.4%), locally advanced primary anal cancer (LAPAC-failure of CRT/T3c/d-T4) (3.0%) and anal cancer recurrence (AR) (2.2%). Among these patients 271 operations were performed, 212 primary and 59 for recurrence. These included 16 sacrectomies, 134 total pelvic exenterations and 121 other multi-visceral exenterative procedures. An R0 resection (no microscopic margin involvement) was achieved in 94.4% and R1 (microscopic margin involvement) in 5.1%. In LAPRC b-TME the R0 rate was 96.1% and for RR it was 79%. The LOS varied from 13.3 to 19.9 days. RR operations had the highest morbidity (CD 1-2, 33.3%) and LAPRC operations had the highest rate of CD 3-4 complications (18.4%). Most (39.6%) of the referred patients were from other UK hospitals. CONCLUSION Advanced colorectal cancer can be successfully treated in a dedicated referral centre, achieving R0 resection in over 90% with low morbidity and mortality. Implementation of a standardized referral pathway is encouraged.

Abstract
AIM The study aimed to establish the oncological outcome of patients who opted for close surveillance with or without adjuvant chemoradiotherapy rather than radical surgery after local excision (LE) of early rectal cancer. METHOD The Royal Marsden Hospital Rectal Cancer database was used to identify rectal cancer patients treated by primary LE from 2006 to 2015. All patients were entered in an intensive surveillance programme. RESULTS Twenty-eight of 34 analysed patients had a high or very high risk of residual disease predicted by adverse histopathological features for which the recommendation had been radical surgery. Eighteen (52%) of the 34 had received radiotherapy following LE. Three-year disease-free survival for the 34 patients was 85% (95% CI 78.8%-91.2%) and overall survival was 100%. Twenty-two of 24 patients with a low tumour which would have required total rectal excision have so far avoided radical surgery and remain disease free at a median follow-up of 3.2 years. CONCLUSION The findings suggest that with modern MRI and clinical surveillance radical surgery can be avoided in patients following initial LE of a histopathologically defined high risk early rectal cancer. These findings are comparable with those obtained after major radical resection and warrant further prospective investigation as a treatment arm in larger prospective trials.

Abstract
AIM To investigate whether the magnetic resonance imaging (MRI) tumour regression grading (mrTRG) scale can be taught effectively resulting in a clinically reasonable interobserver agreement (>0.4; moderate to near perfect agreement). MATERIALS AND METHODS This study examines the interobserver agreement of mrTRG, between 35 radiologists and a central reviewer. Two workshops were organised for radiologists to assess regression of rectal cancers on MRI staging scans. A range of mrTRGs on 12 patient scans were used for assessment. RESULTS Kappa agreement ranged from 0.14-0.82 with a median value of 0.57 (95% CI: 0.37-0.77) indicating good overall agreement. Eight (26%) radiologists had very good/near perfect agreement (κ>0.8). Six (19%) radiologists had good agreement (0.8≥κ>0.6) and a further 12 (39%) had moderate agreement (0.6≥κ>0.4). Five (16%) radiologists had a fair agreement (0.4≥κ>0.2) and two had poor agreement (0.2>κ). There was a tendency towards good agreement (skewness: 0.92). In 65.9% and 90% of cases the radiologists were able to correctly highlight good and poor responders, respectively. CONCLUSIONS The assessment of the response of rectal cancers to chemoradiation therapy may be performed effectively using mrTRG. Radiologists can be taught the mrTRG scale. Even with minimal training, good agreement with the central reviewer along with effective differentiation between good and intermediate/poor responders can be achieved. Focus should be on facilitating the identification of good responders. It is predicted that with more intensive interactive case-based learning a κ>0.8 is likely to be achieved. Testing and retesting is recommended.

Abstract
AIM Several sphincter-preserving techniques have been described with extremely encouraging initial reports. However, more recent studies have failed to confirm the positive early results. We evaluate the adoption and success rates of advancement flap procedures (AFP), fibrin glue sealant (FGS), anal collagen plug (ACP) and ligation of intersphincteric fistula tract (LIFT) procedures based on their evolution in time for the management of anal fistula. METHOD A PubMed search from 1992 to 2015. An assessment of adoption, duration of study and success rate was undertaken. RESULTS We found 133 studies (5604 patients): AFP (40 studies, 2333 patients), FGS (31 studies, 871 patients), LIFT (19 studies, 759 patients), ACP (43 studies, 1641 patients). Success rates ranged from 0% to 100%. Study duration was significantly associated with success rates in AFP (P = 0.01) and FGS (P = 0.02) but not in LIFT or ACP. The duration of use of individual procedures since first publication was associated with success rate only in AFP (P = 0.027). There were no statistically significant differences in success rates relative to the number of the patients included in each study. CONCLUSION Success and adoption rates tend to decrease with time. Differences in patient selection, duration of follow-up, length of availability of the individual procedure and heterogeneity of treatment protocols contribute to the diverse results in the literature. Differences in success rates over time were evident, suggesting that both international trials and global best practice consensus are desirable. Further prospective randomized controlled trials with homogeneity and clear objective parameters would be needed to substantiate these findings.

Abstract
AIM This study compared the operative outcome and long-term survival of three types of hand-sewn coloanal anastomosis (CAA) for low rectal cancer. METHOD Patients presenting with low rectal cancer at a single centre between 2006 and 2014 were classified into three types of hand-sewn CAA: type 1 (supra-anal tumours undergoing transabdominal division of the rectum with transanal mucosectomy); type 2 (juxta-anal tumours, undergoing partial intersphincteric resection); and type 3 (intra-anal tumours, undergoing near-total intersphincteric resection with transanal mesorectal excision). RESULTS Seventy-one patients with low rectal cancer underwent CAA: 17 type 1; 39 type 2; and 15 type 3. The median age of patients was 61.6 years, with a male/female ratio of 2:1. Neoadjuvant therapy was given to 56 (79%) patients. R0 resection was achieved in 69 (97.2%) patients. Adverse events occurred in 25 (35.2%) of the 71 patients with a higher complication rate in type 1 vs type 2 vs type 3 (47.1% vs 38.5% vs 13.3%, respectively; P = 0.035). Anastomotic separation was identified in six (8.5%) patients and pelvic haematoma/seroma in five (7%); two (8.3%) female patients developed a recto-vaginal fistula. Ten (14.1%) patients were indefinitely diverted, with a trend towards higher long-term anastomotic failure in type 1 vs type 2 vs type 3 (17.6% vs 15.5% vs 6.7%). The type of anastomosis did not influence the overall or disease-free survival. CONCLUSION CAA is a safe technique in which anorectal continuity can be preserved either as a primary restorative option in elective cases of low rectal cancer or as a salvage procedure following a failed stapled anastomosis with a less successful outcome in the latter. CAA has acceptable morbidity with good long-term survival in carefully selected patients.

Abstract
AIM The efficacy of sacral nerve stimulation (SNS) in low anterior resection syndrome (LARS) is largely undocumented. A review of the literature was carried out to study this question. METHOD Pubmed, Medline and Cochrane databases were searched for relevant articles up to August 2014. Studies were included if they evaluated the use of SNS following rectal resection and assessed at least one of the following end-points: bowel function, quality of life and ano-neorectal physiology. No restrictions on language or study size were made. RESULTS Seven papers were identified including one case report and six prospective case series. These included 43 patients with a median follow-up of 15 months. After peripheral nerve evaluation definitive implantation was carried out in 34 (79.1%) patients. Overall, 32 (94.1%) of the 34 patients experienced improvement of symptoms which, based on intention to treat, was 32/43 (74.4%). CONCLUSION The review suggests that SNS for faecal incontinence in LARS has success rates comparable to its use for other forms of faecal incontinence.

Abstract
Ventral mesh rectopexy is an approach in the treatment of internal and external rectal prolapse and rectocele. Our aim was to assess whether robotic surgery confers any significant advantages over laparoscopy, and the associated complication rate. Two reviewers performed a literature search using MEDLINE and PubMed databases for studies comparing robotic versus laparoscopic surgery. Five prospective, non-randomised studies were identified and included. A total of 244 patients (101 robotic and 143 laparoscopic) were included in the analysis. Operative time was shorter with laparoscopic surgery, mean weighted difference 27.94 [confidence interval (CI) 19.30-36.57; p < 0.00001]. The conversion rate was not significantly different between groups. There was a trend towards a reduction in length of inpatient stay and early post-operative complications in the robotic group; however, these did not reach statistical significance. Recurrence rates were similar between groups (odds ratio 0.91, CI 0.32-2.63; p = 0.87). Functional results were comparable between groups. Early studies show that robotic ventral rectopexy is a safe option compared to the laparoscopic approach, with overall comparable results. There appeared to be a trend towards a reduction in length of inpatient stay and post-operative complications. These perceived benefits may offset the longer operative times and outlay costs. Larger randomised controlled trials are needed to further evaluate clinical value and cost-effectiveness.

Abstract
AIM Laparoscopic ventral rectopexy (VR) with the use of prosthesis has been advocated for both overt rectal prolapse (ORP) and obstructed defaecation syndrome (ODS). The present study reviews the short-term and functional results of laparoscopic VR. METHOD A search was performed of MEDLINE, EMBASE, Ovid and Cochrane databases on all studies reporting on VR for ORP, ODS and other anatomical abnormalities of the pelvic floor from 2004 until February 2013. No language restrictions were made. All studies on VR were reviewed systematically. The main outcomes were intra-operative complications, conversion, procedure duration, short-term mortality and morbidity, length of stay, recurrence of ORP, recurrence of anatomical disorder, faecal incontinence and constipation, quality of life (QoL) score and patient satisfaction. Quality assessment and data extraction were performed independently by three observers. RESULTS Twenty-three studies including 1460 patients were eligible for analysis. The conversion rate ranged from 0 to 14.3%. No mortality was reported. The immediate postoperative morbidity rate was 8.6%. Length of stay ranged from 1 to 7 days. A significant improvement in constipation and incontinence symptoms was observed in the postoperative period for both ORP and ODS (chi-square test, P < 0.0001). CONCLUSION Laparoscopic VR is a safe and effective procedure for ORP and ODS. Longer follow-up is required, and studies comparing VR with standard rectopexy and stapled transanal rectal resection are not yet available.

Abstract
AIM Several studies have suggested an increased lymph node yield, reduced locoregional recurrence and increased disease-free survival after complete mesocolic excision (CME) for colorectal cancer. This review was undertaken to assess the use of CME for colon cancer by evaluating the technique and its clinical outcome. METHOD A literature search of publications was performed using PubMed and Medline. Only studies published in English were included. Studies assessed for quality and data were extracted by two independent reviewers. End-points included number of lymph nodes per patient, quality of the plane of mesocolic excision, postoperative mortality and morbidity, 5-year locoregional recurrence and 5-year cancer-specific survival. RESULTS There were 34 articles comprising 12 retrospective studies, nine prospective studies and 13 original articles including case series, observational studies and editorials. Of the prospective studies, four reported an increased lymph node harvest and a survival benefit. The others reported an improvement in the quality of the specimen as assessed by histopathological examination. Laparoscopic CME has the same oncological outcome as open surgery but completeness of excision during laparoscopy may be compromised for tumours in the transverse colon. CONCLUSION Studies demonstrate that CME removes significantly more tissue around the tumour including maximal lymph node clearance. There is little information on serious adverse events after CME and a long-term survival benefit has not been proved.

Abstract
AIM A tension-free well vascularized colorectal or coloanal anastomosis is not always possible following rectal or sigmoid resection. The study reports on the short-term and long-term outcome of a modified right colon inversion technique as a means of facilitating a low colorectal or coloanal anastomosis. METHOD All patients who underwent right colonic inversion, a modified Deloyers' procedure, were identified retrospectively from the prospective database of the Colorectal Department of the Royal Marsden Hospital from October 2008 to December 2013. RESULTS There were 14 (nine male) patients of median age 58.7 (45-75) years. The main indication was extensive diverticular disease (50%) and previous colonic surgery (21.4%). A defunctioning stoma was performed in 64.3% which was reversed in all within 3-6 months. Three (21.4%) patients developed postoperative complications (Clavien-Dindo 1-2) and none required reoperation. The median duration of follow-up was 11 months. One (7.2%) patient had one bowel movement per day, 10 (71.4%) patients had two bowel movements per day and three (21.4%) patients had three per day. CONCLUSION The modified right colonic inversion technique is safe and achieves intestinal continuity with a tension-free well vascularized anastomosis. Good function and low morbidity show that the procedure is a credible alternative to ileorectal or ileoanal anastomosis.

Abstract
AIM The influence of the height of rectal cancer from the anal verge on the oncological outcome is controversial. This study aimed to determine the influence of the height of the tumour on the survival of patients treated in a specialized rectal cancer unit. METHOD Patients undergoing surgery for primary rectal cancer from 2006 to 2013 were identified from a prospectively maintained rectal cancer database. Those requiring total or multicompartmental pelvic exenteration were excluded. Low cancer was defined as tumour < 5 cm from the anal verge, as assessed by endoscopy and/or digital rectal examination. The primary outcome was 3-year disease-free survival (DFS). RESULTS Of 340 patients, 203 (59.7%) had low cancer. There were 302 (89%) restorative and 38 (11%) nonrestorative procedures. The rate of positive circumferential resection margin was similar for low compared with high cancer (3.4% vs 2.9%, P = 1.0) and for restorative compared with nonrestorative procedures in low cancer only (3.0% and 5.3%, P = 0.619). Low compared with high anterior resection was associated with increased anastomotic leakage (8.5% vs 2.2%, P = 0.023). Three-year DFS was similar for low and high resection (82% vs 86%, P = 0.305) and between restorative vs nonrestorative procedures in low cancer only (88% vs 77%, P = 0.215). In an adjusted model, low height did not lead to worse survival outcome (3-year DFS hazard ratio 0.54, 95% CI 0.24-1.24, P = 0.147). CONCLUSION With careful planning and a multidisciplinary approach, equivalent oncological outcome can be achieved for patients with rectal cancer who undergo curative surgery regardless of differences in tumour characteristics, location and operation performed.

Abstract
OBJECTIVES A meta-analysis of published literature comparing outcomes after laparoscopic resection (LR) with open resection (OR) for transverse colon tumours. METHODS Medline, PubMed, CINAHL, EMBASE and Cochrane were searched from inception to October 2013. The text words "minimally invasive", "keyhole surgery" and "transverse colon" were used in combination with the medical subject headings "laparoscopy" and "colon cancer". Outcome variables were chosen based upon whether the included articles reported results. A meta-analysis was performed to obtain a summative outcome. RESULTS Six comparatives involving 444 patients were analysed. Of them 245 patients were in the LR group and 199 in the OR group. There was a significant increase in operative time in the LR group compared with the OR group [random effects model: SMD = -0.65, 95% CI (-1.01, -0.30), z = -3.60, p < 0.001] but there was significant heterogeneity amongst trials (Q = 15.51, df = 5, p = 0.008, I(2) = 68). There was less blood loss in the LR group [fixed effects model: SMD = 0.70, 95% CI (0.47, 0.93), z = 6.01, p < 0.001] and patients returned to oral diet earlier [random effects model: SMD = 0.78, 95% CI (0.40, 1.16), z = 4.01, p < 0.001] and had a reduced time to functioning bowel [fixed effects model: SMD = 0.86, 95% CI (0.60, 1.11), z = 6.63, p < 0.001]. No difference was seen for overall morbidity (p = 0.76) or mortality (p = 0.58). CONCLUSIONS LR of transverse colon tumours is a safe and effective technique. Although there is an increase in operating time, operative and clinical outcomes of intraoperative blood loss and faster recovery are seen with laparoscopic procedures.

Abstract
AIM Nonresponse to neoadjuvant therapy is a significant challenge for clinicians managing solid cancers. This study aimed to determine whether epithelial mesenchymal transition (EMT) was associated with nonresponse to neoadjuvant therapy in patients with locally advanced rectal cancer. METHOD Representative tissue specimens from the tumour-invasive front of consecutive patients undergoing resection of rectal cancer from 2009 to 2011 were used. Patients with marked regression to neoadjuvant therapy were classified as responders and the remainder were classified as nonresponders. Markers of EMT included reduced immunohistochemical expression of membranous E-cadherin, increased nuclear beta-catenin expression and tumour budding. In-situ hybridization was used to assess the expression of microRNA-200c (mir200c), an upstream master-regulator of EMT. RESULTS Of 103 patients undergoing resection of rectal cancer, 69 received neoadjuvant chemoradiotherapy; 65% of these were nonresponders. Reduced expression of mir200c was significantly associated with a higher T grade. Reduced membranous E-cadherin, increased nuclear beta-catenin and tumour budding individually predicted the presence of extramural vascular invasion. Reduced E-cadherin, nucleic beta-catenin, reduced expression of mir200c and tumour budding were all significantly associated with nonresponse to neoadjuvant therapy (all P < 0.001). Reduced E-cadherin and expression of mir200c were both associated with reduced cancer-specific survival (log-rank P-values 0.036 and 0.009, respectively). CONCLUSION Targeted biomarkers of EMT were associated with nonresponse to neoadjuvant therapy and reduced survival in advanced rectal cancer. EMT may provide a practical clinical biomarker and a novel therapeutic target to improve the proportion of patients who respond to neoadjuvant therapy.

Abstract
BACKGROUND With an ageing population, surgery is increasingly offered to elderly patients with rectal cancer, although outcomes for the oldest patients remain poorly defined. This study aimed to determine whether operative intervention improves outcome in elderly patients. METHOD Patients aged 18+ years diagnosed with rectal adenocarcinoma between 1998 and 2009 were identified from the Surveillance, Epidemiology, and End Results database. The primary endpoint was adjusted hazard ratios (HR) for 5-year cancer specific survival (CSS); the secondary endpoint was 5-year overall survival (OS). RESULTS With increasing age, patients were less likely to undergo surgery, receive a complete stage or receive neoadjuvant radiotherapy. CSS and OS increasingly diverged with age in patients undergoing surgery. Those aged 80+ had reduced CSS compared to those aged 70-79 years (stages I-III, respective adjusted HR 2.14, 1.58, 1.48, all p < 0.001). However, stage II patients aged 80+ treated with resection and neoadjuvant therapy had similar survival to those aged 70-79 years (adjusted HR 1.26, p = 0.149). For only patients aged 80+ years, those treated non-operatively had lower survival than those undergoing surgery, who in turn had the best survival when treated with neoadjuvant radiotherapy (adjusted HR 0.74, p = 0.001). CONCLUSION Contrary to common expectation, in patients aged over 80 with rectal cancer, surgery with or without other modalities was associated with better survival than non-operative treatment. Despite selection bias in this observational study, these findings support consideration of maximal therapy regardless of age in selected patients deemed to be fit, since this leads to outcomes equivalent to younger patients.

Abstract
AIM Extramural vascular invasion (EMVI) has been proposed as an adverse prognostic indicator in colorectal cancer, although its use remains both variable and controversial. This study aimed to determine the survival effect of EMVI in T4 rectal cancer. METHOD Patients undergoing surgery with curative intent for primary T4 rectal cancer between 1971 and 2011 were included from two prospectively collected rectal cancer databases. The main end-point was 3-year survival. RESULTS From 1142 patients undergoing resection of rectal cancer during the study period, 126 (11.0%) had T4 rectal cancer and were included in the study group. Sphincter preservation was performed in 61 (48%) and a pathologically negative resection margin (R0) was achieved in 104 patients (82.5%). EMVI was present in 51 patients (40.5%) and was an independent predictor of positive lymph node status (adjusted odds ratio 2.66, P = 0.013). Considering all patients, EMVI was associated with reduced overall survival (P = 0.007) and disease-free survival (P = 0.002), but not local recurrence-free survival (P = 0.198). In only those undergoing R0 resection, EMVI predicted reduced disease-free survival with positive nodal status (P = 0.021); it did not predict survival with negative nodal status. CONCLUSION Overall, EMVI was a strong prognostic marker of survival. However, after complete surgical resection in patients with node-negative disease, EMVI did not predict local recurrence.

Abstract
AIM The benefits of a laparoscopic approach to restorative proctocolectomy (RPC) are controversial. The aim of this meta-analysis was to compare the outcome following laparoscopic and open RPC, with particular attention to adverse events and long-term function. METHOD A systematic search of the MEDLINE, EMBASE and Ovid databases was performed for studies published until March 2012. The primary end-point was long-term function. Secondary end-points were intra-operative details, short-term postoperative outcome and postoperative adverse events. Weighted mean difference (WMD) and odds ratio (OR) were calculated using fixed/random effect meta-analytic techniques. RESULTS The final analysis included 27 comparative studies of 2428 patients, of whom 1097 (45.1%) underwent laparoscopic surgery. A laparoscopic approach was associated with a significantly longer operation time (WMD 70.1 min, P < 0.001), shorter length of hospital stay (WMD -1.00 day, P < 0.001), reduced intra-operative blood loss (WMD -89.10 ml, P < 0.001) and a lower incidence of wound infection (OR 0.60, P < 0.005). No significant differences were observed in the rate of pouch failure. Although there was no significant difference in the number of daily bowel movements (OR 0.04, P = 0.950), laparoscopic surgery led to fewer nocturnal bowel movements (WMD -1.14, P < 0.001) and reduced pad usage during the day (OR 0.22, P < 0.001) and night (OR 0.33, P < 0.001). The post hoc power to detect differences in adverse event rates ranged from 5% to 42%. CONCLUSION Laparoscopic and open approaches to RPC produced equivalent adverse event rates and long-term functional results. However, the present evidence is underpowered to detect true differences in adverse event rates.

Abstract
AIM Complete surgical resection is considered the best treatment for recurrent rectal cancer (RRC). The aim of the study was to compare survival outcomes from operative and nonoperative patients presenting with RRC. METHOD Patients with RRC whose management was discussed by a tertiary referral specialist multidisciplinary team between January 2007 and August 2011 were identified from a prospectively maintained database. The primary end-point was 3-year overall survival. RESULTS Of 127 patients with RRC, it was isolated to the pelvis in 105 and associated with distant disease at presentation in 22. From the time of primary surgery to first recurrence, 1-, 3-, 5- and 10-year local recurrence rates were 22%, 72%, 85% and 96%, respectively. The number of operated patients available at 1, 2 and 3 years' follow-up was 53, 34 and 23, respectively. Of 70 patients who underwent pelvic resection for recurrence, 64% received R0, 20% received R1 and 16% received R2 resections. Corresponding 3-year overall survival rates were 69%, 56% and 20% (P=0.011). There was no significant difference in survival between R2 resection and those managed nonoperatively (hazard ratio=1.258; P=0.579). Those undergoing surgery for pelvic recurrence affecting one or more compartments had a worse prognosis than those with single-compartment involvement (hazard ratio=2.640; P=0.027). Three-year local recurrence-free survival was 80% with R0 resection vs 60% with R1 resection. CONCLUSION Most recurrences occur within 5 years of primary surgery, although some occur up to 10 years later. R0 resection is the treatment of choice. There was no survival benefit of R2 resection over nonresected recurrences.

Abstract
AIM To determine the presence and duration of survival advantages was investigated for resection margin status (R0, R1 or R2) following surgery for locally recurrent rectal cancer (LRRC). METHOD A systematic review of the literature was performed for studies comparing resection margin status for LRRC. Weighted mean differences and meta-analysis of hazard ratios were used as a measure of median and overall cumulative survival. RESULTS Twenty-two studies were included, providing outcome for 1460 patients undergoing surgery for LRRC. 57% underwent an R0 resection, 25% an R1 resection and 11% an R2 resection. The most commonly performed operations were abdominoperineal excision (35%), exenteration (23%) and anterior resection (21%). The range of median survival per resection margin was R0 28-92 months, R1 12-50 months, R2 6-17 months. Patients undergoing an R0 resection survived on average for 37.6 (95% confidence interval: 23.5-51.7) months longer than those undergoing R1 resection and 53.0 (31.2-74.8) months longer than those undergoing R2 resection. This correlated to a hazard ratio of 2.03 (1.73-2.38) for R0 vs R1 and 3.41 (2.21-5.25) for R0 vs R2. Patients undergoing R1 resection survived on average 13.3 (7.23-19.4) months longer than those undergoing R2 resection [hazard ratio of 1.68 (1.33-2.12)]. CONCLUSION Patients undergoing R0 resection have the greatest survival advantage following surgery for recurrent rectal cancer. There is a survival advantage for R1 over R2 resection, but there may be no benefit of R2 resection over palliative treatment.

Abstract
Forty to fifty percent of colorectal cancer (CRC) patients develop colorectal liver metastases (CLM) that are either synchronous or metachronous in presentation. Clarifying whether there is a biological difference between the two groups of liver metastases or their primaries could have important clinical implications. A systematic review was performed using the following resources: MEDLINE from PubMed (1950 to present), Embase, Cochrane and the Web of Knowledge. Thirty-one articles met the inclusion criteria. The review demonstrated that the majority of studies found differences in molecular marker expression between colorectal liver metastases and their respective primaries in both the synchronous and metachronous groups. Studies investigating genetic aberrations demonstrated that the majority of changes in the primary tumour were 'maintained' in the colorectal liver metastases. A limited number of studies compared the primary tumours of the synchronous and metachronous groups and generally demonstrated no differences in marker expression. Although there were conflicting results, the colorectal liver metastases in the synchronous and metachronous groups demonstrated some differences in keeping with a more aggressive tumour subtype in the synchronous group. This review suggests that biological differences may exist between the liver metastases of the synchronous and metachronous groups. Whether there are biological differences between the primaries of the synchronous and metachronous groups remains undetermined due to the limited number of studies available. Future research is required to determine whether differences exist between the two groups and should include comparisons of the primary tumours.

Abstract
Abstract
Background
The aim was to assess the indications for and outcomes of abdominosacral resection for patients with locally advanced primary and recurrent rectal cancer.
Methods
Consecutive patients undergoing abdominosacral resection between January 2006 and December 2011 were identified from a prospectively maintained database. The main endpoints were 3-year local recurrence-free (LRFS) and disease-free (DFS) survival.
Results
Thirty patients underwent abdominosacral resection, 22 for recurrent rectal cancer and eight for locally advanced primary cancer. Sacrectomy was performed at S1/2 in five, S3 in 11 and S4/5 in 14 patients. R0 resection was achieved in 23 patients; all seven positive margins (R1) were in patients with recurrent disease. There were no deaths in hospital or within 30 days. S1/2 sacrectomy was associated with the highest rate of major complications (60 per cent versus 27 and 29 per cent for S3 and S4/5 respectively) and long-term complications (60, 36 and 14 per cent). Overall 3-year LRFS was 66 per cent and 3-year DFS was 55 per cent. Both were significantly better in patients with negative compared with positive margins (LRFS: 87 versus 0 per cent, P < 0·001; DFS: 71 versus 0 per cent, P = 0·033).
Conclusion
Abdominosacral resection was associated with long-term survival in carefully selected patients with advanced rectal cancer. Postoperative complications were common and often multiple. Sacrectomy for locally advanced primary rectal cancer was associated with a low margin-positive rate and should be considered as an acceptable treatment. Margin-positive resection was associated with poor survival outcomes and should be avoided.

Abstract
BACKGROUND The significance of magnetic resonance imaging (MRI)-suspected pelvic sidewall (PSW) lymph node involvement in rectal cancer is uncertain. METHODS Magnetic resonance images were reviewed retrospectively by specialist gastrointestinal radiologists for the presence of suspicious PSW nodes. Scans and outcome data were from patients with biopsy-proven rectal cancer and a minimum of 5 years' follow-up in the Magnetic Resonance Imaging and Rectal Cancer European Equivalence Study. Overall disease-free survival (DFS) was analysed using the Kaplan-Meier product-limit method and stratified according to preoperative therapy. Binary logistic regression was used to match patients for propensity of clinical and staging characteristics, and further survival analysis was carried out to determine associations between suspicious PSW nodes on MRI and survival outcomes. RESULTS Of 325 patients, 38 (11·7 per cent) had MRI-identified suspicious PSW nodes on baseline scans. Such nodes were associated with poor outcomes. Five-year DFS was 42 and 70·7 per cent respectively for patients with, and without suspicious PSW nodes (P < 0·001). Among patients undergoing primary surgery, MRI-suspected PSW node involvement was associated with worse 5-year DFS (31 versus 76·3 per cent; P = 0·001), but the presence of suspicious nodes had no impact on survival among patients who received preoperative therapy. After propensity matching for clinical and tumour characteristics, the presence of suspicious PSW nodes on MRI was not an independent prognostic variable. CONCLUSION Patients with suspicious PSW nodes on MRI had significantly worse DFS that appeared improved with the use of preoperative therapy. These nodes were associated with adverse features of the primary tumour and were not an independent prognostic factor.

Abstract
PURPOSE It is a widely held view that anterior resection (AR) for rectal cancer is an oncologically superior operation to abdominoperineal excision (APE). However, some centres have demonstrated better outcomes with APE. We conducted a systematic review of high-quality studies within the total mesorectal excision (TME) era comparing outcomes of AR and APE. METHODS A literature search was performed to identify studies within the TME era comparing AR and APE with regard to the following: circumferential resection margin (CRM) status, tumour perforation rates, specimen quality, local recurrence, overall survival (OS; 3 or 5 year), cancer-specific survival (CSS) and disease-free survival (DFS). Additional data regarding patient demographics and tumour characteristics was collected. RESULTS Twenty four studies fulfilled the eligibility criteria with Newcastle-Ottawa scores of six or greater. Where a significant difference was found, all studies reported lower and more advanced tumours for APE and 4/5 studies observed more frequent use of neoadjuvant and adjuvant therapies in APE patients. Tumour perforation rates and CRM involvement where reported, were significantly greater for APE. 8 out of 10 studies showing significant differences in local recurrence reported higher rates for APE but no differences were observed with distant recurrence. Where differences were noted, AR was reported to have increased DFS, CSS and OS compared to APE. CONCLUSIONS Patients treated with AR have lower rates of tumour perforation and CRM involvement and tend to have better outcomes with regard to disease recurrence and survival. However, tumours treated by APE are lower and more locally advanced.

Abstract
BACKGROUND A pathologically involved margin in rectal cancer is defined as tumour within 1 mm of the surgical resection margin. There is no standard definition of a predicted safe margin on magnetic resonance imaging (MRI). The aim of this study was to assess which cut-off (1, 2 or 5 mm) was the best predictor of local recurrence based on preoperative MRI assessment of the circumferential resection margin (CRM). METHODS Data were collected prospectively on the distance between the tumour and mesorectal fascia for patients with documented radiological margin status in the MERCURY study. Positive margin and local recurrence rates were compared for MRI distances from the tumour to the mesorectal fascia of 1 mm or less, more than 1 mm up to 2 mm, more than 2 mm up to 5 mm, and more than 5 mm. The Cox proportional hazard regression method was used to determine the effect of level of margin involvement on time to local recurrence. RESULTS Univariable analysis showed that, relative to a distance measured by MRI of more than 5 mm, the hazard ratio (HR) for local recurrence was 3·90 (95 per cent confidence interval 1·99 to 7·63; P < 0·001) for a margin of 1 mm or less, 0·81 (0·36 to 1·85; P = 0·620) for a margin of more than 1 mm up to 2 mm, and 0·33 (0·10 to 1·08; P = 0·067) for a margin greater than 2 mm up to 5 mm. Multivariable analysis of the effect of MRI distance to the mesorectal fascia and preoperative treatment on local recurrence showed that a margin of 1 mm or less remained significant regardless of preoperative treatment (HR 3·72, 1·43 to 9·71; P = 0·007). CONCLUSION For preoperative staging of rectal cancer, the best cut-off distance for predicting CRM involvement using MRI is 1 mm. Using a cut-off greater than this does not appear to identify patients at higher risk of local recurrence.
