Abstract
Wheat is a staple food crop that provides a significant portion of the world's daily caloric intake, serving as a vital source of carbohydrates and dietary fiber for billions of people. Seed shape studies of wheat typically involve the use of digital image analysis software to quantify various seed shape parameters such as length, width, area, aspect ratio, roundness, and symmetry. This study presents a comprehensive investigation into the water-absorbing capacity of seeds from 120 distinct wheat lines, leveraging digital image analysis techniques facilitated by SmartGrain software. Water absorption is a pivotal process in the early stages of seed germination, directly influencing plant growth and crop yield. SmartGrain, a powerful image analysis tool, was employed to extract precise quantitative data from digital images of wheat seeds, enabling the assessment of various seed traits in relation to their water-absorbing capacity. The analysis revealed significant transformations in seed characteristics as they absorbed water, including changes in size, weight, shape, and more. Through statistical analysis and correlation assessments, we identified robust relationships between these seed traits, both before and after water treatment. Principal Component Analysis (PCA) and Agglomerative Hierarchical Clustering (AHC) were employed to categorize genotypes with similar trait patterns, providing insights valuable for crop breeding and genetic research. Multiple linear regression analysis further elucidated the influence of specific seed traits, such as weight, width, and distance, on water-absorbing capacity. Our study contributes to a deeper understanding of seed development, imbibition, and the crucial role of water absorption in wheat. These insights have practical implications in agriculture, offering opportunities to optimize breeding programs for improved water absorption in wheat genotypes. The integration of SmartGrain software with advanced statistical methods enhances the reliability and significance of our findings, paving the way for more efficient and resilient wheat crop production. Significant changes in wheat seed shape parameters were observed after imbibition, with notable increases in area, perimeter, length, width, and weight. The length-to-width ratio (LWR) and circularity displayed opposite trends, with higher values before imbibition and lower values after imbibition.

Abstract
BACKGROUND Empty pelvis syndrome (EPS) is a significant source of morbidity following pelvic exenteration (PE), but is undefined. EPS outcome reporting and descriptors of radicality of PE are inconsistent; therefore, the best approaches for prevention are unknown. To facilitate future research into EPS, the aim of this study is to define a measurable core outcome set, core descriptor set and written definition for EPS. Consensus on strategies to mitigate EPS was also explored. METHOD Three-stage consensus methodology was used: longlisting with systematic review, healthcare professional event, patient engagement, and Delphi-piloting; shortlisting with two rounds of modified Delphi; and a confirmatory stage using a modified nominal group technique. This included a selection of measurement instruments, and iterative generation of a written EPS definition. RESULTS One hundred and three and 119 participants took part in the modified Delphi and consensus meetings, respectively. This encompassed international patient and healthcare professional representation with multidisciplinary input. Seventy statements were longlisted, seven core outcomes (bowel obstruction, enteroperineal fistula, chronic perineal sinus, infected pelvic collection, bowel obstruction, morbidity from reconstruction, re-intervention, and quality of life), and four core descriptors (magnitude of surgery, radiotherapy-induced damage, methods of reconstruction, and changes in volume of pelvic dead space) reached consensus-where applicable, measurement of these outcomes and descriptors was defined. A written definition for EPS was agreed. CONCLUSIONS EPS is an area of unmet research and clinical need. This study provides an agreed definition and core data set for EPS to facilitate further research.

Abstract
A series of new phosphorylated derivatives of didanosine were designed, synthesized and evaluated their anticancer effects on human breast cancer cells. Their binding affinities were evaluated against aromatase enzyme and the molecular docking studies demonstrated that 9a, 9h and 9i exhibited high binding interactions than the parent molecule (ddI) and other derivatives; evaluated the aromatase enzyme inhibition. The cell viability, cell proliferation, lactate dehydrogenase showed potential anti-proliferative in dose dependent manner, these results were well correlated with hoesch stain and DNA fragmentation on MDA-MB-231 breast cancer cell lines. Cytotoxicity results disclosed that tryptophan amino acid ester substituted derivative 9i showed potential cell death against MDA-MB-231 cancer cell lines. Furthermore, compound 9i has great potential significance for further investigations (in vivo).

Abstract
Eagle Syndrome is a pain syndrome of rare and unwonted incidence. Forbearer has an elongated styloid process or a calcified stylohyoid ligament, suppressing glossopharyngeal nerve leading to a mélange of symptoms including sporadic cervicofacial pain, headache, and foreign body sensation. Here we present case of a 65 year old military man of south Asian origin, who presented with complaints of sudden episodes of blackouts for past five years and pain in neck while turning head to left for past two months. Patient's ultrasound Doppler showed marked narrowing of proximal left internal carotid artery with approximate diametric stenosis of 70% according to The North American Symptomatic Carotid Endarterectomy Trial (NASCET).Further studies of MRI Brain was done,revealing small Foci of restricted diffusion along Territory of Left MCA along with age related Microangiopathic cerebral changes. CT Scan of neck was also done which showed Abnormal elongation of bilateral styloid process more on the left side. The case was discussed in a Multidisciplinary Team Meeting comprising ENT surgeon, vascular surgeon and surgical excision was planned through trans cervical approach. Surgery was successful as seen by post op and follow up scans.

Abstract
This study determines the associations among serum lipid profiles, risk of cardiovascular disease, and persistent organic pollutants. Using Gas chromatography technique, the intensity of toxic pollutant residues in serum samples of Hypertensive patients were measured. Based on statistical analysis, the effects of different covariates namely pesticides, age, systolic blood pressure, diastolic blood pressure, and lipid profile duration was checked using the logistic regression model. Statistical computation was performed on SPSS 22.0. The P-values of F-Statistic for each lipid profile class are greater than 0.01 (1%), therefore we cannot reject the null hypothesis for all cases. The estimated coefficients, their standard errors, Wald Statistic, and odds ratio of the binary logistic regression model for different lipid profile parameters indicate if pesticides increase then the logit value of different lipid profile parameters changes from -0.46 to -0.246 except LDL which increases by 0.135. The study reports a significantly increased threat of cardiovascular disease with increased concentrations of toxic pollutants.

Abstract
AIM At presentation, 15-20% of patients with rectal cancer already have synchronous liver metastases. The aim of this study was to determine the surgical and survival outcomes in patients with advanced rectal cancer who underwent combined pelvic exenteration and liver (oligometastatic) resection. METHOD Data from 20 international institutions that performed simultaneous pelvic exenteration and liver resection between 2007 and 2017 were accumulated. Primarily, we examined perioperative outcomes, morbidity and mortality. We also assessed the impact that margin status had on survival. RESULTS Of 128 patients, 72 (56.2%) were men with a median age of 60 years [interquartile range (IQR) 15 years]. The median size of the liver oligometastatic deposits was 2 cm (IQR 1.8 cm). The median duration of surgery was 406 min (IQR 240 min), with a median blood loss of 1090 ml (IQR 2010 ml). A negative resection margin (R0 resection) was achieved in 73.5% of pelvic exenterations and 66.4% of liver resections. The 30-day mortality rate was 1.6%, and 32% of patients had a major postoperative complication. The 5-year overall survival for patients in whom an R0 resection of both primary and metastatic disease was achieved was 54.6% compared with 20% for those with an R1/R2 resection (P = 0.006). CONCLUSION Simultaneous pelvic exenteration and liver resection is feasible, with acceptable morbidity and mortality. Simultaneous resection should only be performed where an R0 resection of both pelvic and hepatic disease is anticipated.

Abstract
BACKGROUND Better understanding of the impact of metachronous metastases in locally advanced and recurrent rectal cancer may improve decision-making. The aim of this study was to investigate factors influencing metachronous metastasis and its impact on survival in patients who have a beyond total mesorectal excision (bTME) operation. METHODS This was a retrospective study of consecutive patients who had bTME surgery for locally advanced and recurrent rectal cancer at a tertiary referral centre between January 2006 and December 2016. The primary outcome was overall survival. Cox proportional hazards regression analyses were performed. The influence of metachronous metastases on survival was investigated. RESULTS Of 220 included patients, 171 were treated for locally advanced primary tumours and 49 for recurrent rectal cancer. Some 90·0 per cent had a complete resection with negative margins. Median follow-up was 26·0 (range 1·5-119·6) months. The 5-year overall survival rate was 71·1 per cent. Local recurrence and metachronous metastasis rates were 11·8 and 22·2 per cent respectively. Patients with metachronous metastases had a worse overall survival than patients without metastases (median 52·9 months versus estimated mean 109·4 months respectively; hazard ratio (HR) 6·73, 95 per cent c.i. 3·23 to 14·00). Advancing pT category (HR 2·01, 1·35 to 2·98), pN category (HR 2·43, 1·65 to 3·59), vascular invasion (HR 2·20, 1·22 to 3·97) and increasing numbers of positive lymph nodes (HR 1·19, 1·07 to 1·16) increased the risk of metachronous metastasis. Nine of 17 patients (53 per cent) with curatively treated synchronous metastases at presentation developed metachronous metastases, compared with 40 of 203 (19·7 per cent) without synchronous metastases (P = 0·002). Corresponding median length of disease-free survival was 17·5 versus 90·8 months (P < 0·001). CONCLUSION As metachronous metastases impact negatively on survival after bTME surgery, factors associated with metachronous metastases may serve as selection tools when determining suitability for treatment with curative intent.

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
Objectives: To evaluate any association between the frequency of hereditary hemochromatosis (HFE) gene mutation (H63D and C282Y) and iron overload in beta-thalassemia major (BTM) patients. Methods: The case-control study was conducted from June 2016 to February 2018. Blood samples from 204 BTM patients and 204 normal controls were taken from the Sundas Foundation Blood Bank. These samples were analyzed for serum ferritin assay and HFE mutation. Ferritin level was measured on the ARCHITECT 1000SR. Both patient and control samples were analyzed for mutations using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Results: Serum ferritin levels for all patients were >1000ng/mL. The p.H63D mutation was observed in 23 (11.3%) cases, out of which 19 cases were heterozygous for p.H63D and 4 cases were homozygous. In control samples, 4 cases (2%) were found heterozygous for the p.H63D, and no homozygous mutation was found. Significantly high serum ferritin levels were found in BTM patients with the H63D mutation (p=0.00). In the case of p.C282Y, neither homozygous nor heterozygous mutation was found in patients or in controls. Conclusion: H63D polymorphism is associated with iron overload in BTM patients. Larger-scale research is required to give an elaborated view of the association of the HFE mutation with iron overload in these patients and to confirm our conclusion.

Abstract
Background and context: Rotary International (RI) is an international service organization whose stated purpose is to bring together business and professional leaders to provide humanitarian services, encourage high ethical standards in all vocations, and to advance goodwill and peace around the world. The Rotary Club of Dhaka Mavericks, with the notion to work on cancer care has partnered with an US-based organization to bring cancer care specialists from the US. These 2 partners mainly work with the National Institute of Cancer Research and Hospital, the government-owned tertiary level cancer care and research institute in Bangladesh, to transfer the skills and provide vocational training to Bangladeshi oncologists, nurses and allied health professionals by oncologists, nurses and allied health professionals from the US. Aim: The overall aim of this project is to create a cadre of cancer care professionals - oncologists, nurses and allied health professionals - in Bangladesh who would have the vocational skills through on-the-job training and skills transfer session from experienced and skilled oncologists, nurses and allied health professionals from the US. Strategy/Tactics: The international platform of RI has been used to reach out to a US-based not-for-profit organization Partners for World Health. This US-based organization has sourced in cancer care professionals from the US and brought them to Bangladesh using the partnership of 1 rotary club in the US and another rotary club in Dhaka. Later on, these 2 Rotary Clubs and Partners for World Health collaborated with the National Institute of Cancer Research and Hospital, where this long-term skills transfer and vocational sessions are taking place. Program process: In this partnership, the Rotary Clubs and the US-based organization arranged all necessary funding and relevant permission and accreditation, while the National Institute of Cancer Research and Hospital patients - who were served - and oncologists, nurses and allied health professionals - who were trained. Outcomes: This partnership is currently for 5 years starting from October of 2017. The plan is to have 2-week vocational and skills transfer session every 6 months. The first session took place in October of 2017 and the second one on March of 2018. The third session will take place on October of 2018. In the October 2018 session, total 100 doctors and 35 nurses were trained on US standard cancer treatment protocols and chemotherapy administration. Number of complicated surgical techniques were also taught to the Bangladeshi surgeons by the US team. During the March session, the focus was on radiation oncology. A total of 100 radiation oncologists were trained on March of 2018.

Abstract
Introduction Laparoscopic Roux-en-Y gastric bypass (LRYGB) is technically demanding and has an associated learning curve. We published previously that bariatric fellowship reduces the learning curve of primary LRYGB and improves patient outcomes after one year of independent practice. However, the long-term effect of fellowship is unknown. We therefore aimed to compare the 30-day outcomes of LRYGB between the first year of a surgeon's independent practice with the subsequent six years. Materials and methods A prospective database of patients undergoing primary LRYGB under a single surgeon from March 2010 until February 2017 was analysed. Two groups were studied: first year (< 1 year) and the subsequent six years (≥ 1 year) of independent practice. Patient demographics, length of hospital stay, conversion to open surgery, perioperative complications and mortality were compared. Results Among 279 eligible patients, 74 (26.5%) were in the < 1 year group and 205 (73.5%) in ≥ 1 year group. The preoperative risk scores, American Society of Anesthesiologists (ASA) grade, P = 0.00; obesity surgery mortality risk score (OS-MRS), P = 0.04) were significantly higher in ≥ 1 year group. There was no significant difference in perioperative outcomes (length of stay, P = 0.38; total complications, P = 0.20; readmissions, P = 1.00; reoperations, P = 0.60) between the two groups. Conclusions Bariatric fellowship reduces the learning curve for LRYGB and helps to achieve excellent outcomes in the first and subsequent years of independent practice. The higher risk profile of ≥ 1 year group did not equate to an increase in complications, suggesting that experience and standardisation may help in handling complex cases. To our knowledge, this represents the only such study in the literature.

METHOD A systematic review of the literature was performed. A random effects meta-analytical model was used to compare adverse events and functional outcome. RESULTS Thirty comparative studies comparing J, W, S and K pouch designs were included. No significant differences were identified between the different pouch designs with regard to anastomotic dehiscence, anastomotic stricture, pelvic sepsis, wound infection, pouch fistula, pouch ischaemia, perioperative haemorrhage, small bowel obstruction, pouchitis and sexual dysfunction. The W and K designs resulted in fewer cases of pouch failure compared with the J and S designs. J pouch construction resulted in a smaller maximum pouch volume compared with W and K pouches. Stool frequency per 24 h and during daytime was higher following a J pouch than W, S or K constructions. The J design resulted in increased faecal urgency and seepage during daytime compared with the K design. The use of protective pads during daytime and night-time was greater with a J pouch compared to S or K. The use of antidiarrhoeal medication was greater after a J reservoir than a W reservoir. Difficulty in pouch evacuation requiring intubation was higher with an S pouch than with W or J pouches. CONCLUSION Despite its ease of construction and comparable complication rates, the J pouch is associated with higher pouch failure rates and worse function. Patient characteristics, technical factors and surgical expertise should be considered when choosing pouch design.

Abstract
AIM The aim of this study was to evaluate whether adjuvant chemotherapy will affect recurrence rate or disease-free and overall survival in patients with rectal adenocarcinoma who were staged with MRI node-positive disease (mrN+) preoperatively. These patients underwent neoadjuvant chemoradiotherapy with curative rectal cancer surgery and their pathological staging was negative for nodal disease (ypN0). There is no consensus on the role of adjuvant chemotherapy in such patients. METHOD Patients who received neoadjuvant chemoradiotherapy and underwent curative rectal cancer surgery for rectal adenocarcinoma staged as [mrTxN+M0] on MRI staging and who on pathological staging were found to be [ypTxN0M0] were retrospectively identified from January 2008 December 2012 from two tertiary referral centres (Royal Marsden Hospital, London and Saint-Andre Hospital, Bordeaux). RESULTS One hundred and sixty-three patients were recruited and, after propensity matching at a ratio of 2:1, n = 80 patients were divided to receive adjuvant (n = 28) or no adjuvant treatment (n = 52). A comparison of adjuvant chemotherapy vs no adjuvant therapy showed that the mean overall survival was 2.67 vs 3.60 years (P = 0.42) and disease-free survival was 2.27 vs 3.32 years (P = 0.14). CONCLUSION This study found no significant difference in survival or disease recurrence between patients who received adjuvant chemotherapy and patients who did not. There is no clear evidence to support or dismiss the use of adjuvant chemotherapy for patients who were node positive on preoperative MRI and node negative on histopathological staging. Further multicentre prospective randomized trials are needed to identify the appropriate treatment regime for this group of patients.

Abstract
Introduction Early rectal cancer (ERC) assessment should include prediction of the potential excision plane to safely remove lesions with clear deep margins and feasibility of organ preservation. Method MRI accuracy for differentiating ≤T1sm2 (partially preserved submucosa) or ≤T2 (partially preserved muscularis) versus >T2 tumours was compared with the gold standard of pT stage T1sm1/2 versus ≤pT2 versus >pT2. N stage was also compared. The MRI protocol employed a standard surface phased array coil with a high resolution (0.6×0.6×3 mm resolution). The staging data were analysed from a prospectively recorded database of all ERC (≤mrT3b) treated by primary surgery. Results Of 65 <mrT3b tumours, 45 were ≤pT2 and 14 were ≤pT1sm2. MRI accuracy for ≤T1sm2 was 89% (95% CI 63% to 87%), positive predictive value (PPV) 77% and negative predictive value (NPV) 92%, and for ≤T2 89% (95% CI 79% to 95%), PPV 93% and NPV 81%. Interobserver agreement between two experienced radiologists was >0.7 suggesting good agreement. 44 out of 65 patients underwent radical surgery and 22 out of 44 were ≤mrT2. MRI accuracy to predict lymph node status was 84% (95% CI 70% to 92%), PPV 71% and NPV 90%. Among the 21 out of 65 (32%) patients undergoing local excision or TEM, 20 out of 21 were staged as MR≤T2 and confirmed as such by pathology. On follow-up, none had relapse. If the decision had been made to offer local excision on MRI TN staging rather than clinical assessment, a significant increase in organ preservation surgery from 32% to 60% would have been observed (difference 23%, 95% CI 9% to 35%). Conclusions MRI is a useful tool for multidisciplinary teams (MDTs) wishing to optimise treatment options for ERC; these study findings will be validated in a prospective multicentre trial.

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
We report a histologically proven case of synovial haemangioma of the knee in a 14-month old girl who presented to the emergency department with an acute 1-day history of refusing to weight-bear on the right leg and a preceding 3-week history of a right knee lump. Physical examination revealed a non-tender, soft lump over the lateral infrapatellar region. Radiographs revealed a poorly defined soft tissue density over the infrapatellar fat pad and a suprapatellar joint effusion. Ultrasound was used to confirm the presence of a vascular soft tissue mass compatible with a synovial haemangioma within the infrapatellar fat pad which showed both intra-articular and extra-articular extension. There was good correlation of the ultrasound findings with magnetic resonance imaging (MRI), highlighting the potential clinical utility of ultrasound as an alternative imaging modality in establishing the pre-operative diagnosis and extent of a synovial haemangioma about the knee joint.

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 The surgical technique used for transanal total mesorectal excision (TaTME) was reviewed including the oncological quality of resection and the peri-operative outcome. METHOD A literature search of MEDLINE, Embase, Science Citation Index Expanded and Cochrane was performed in order to identify studies reporting on TaTME. RESULTS Thirty-six studies (eight case reports, 24 case series and four comparative studies) were identified, reporting 510 patients who underwent TaTME. The mean age ranged from 43 to 80 years and the mean body mass index from 21.7 to 31.8 kg/m(2) . The mean distance of the tumour from the anal verge ranged from 4 to 9.7 cm. The mean operation time ranged from 143 to 450 min and mean operative blood loss from 22 to 225 ml. The ratio of hand-sewn coloanal to stapled anastomoses performed was 2:1. One death was reported and the peri-operative morbidity rate was 35%. The anastomotic leakage rate was 6.1% and the reoperation rate was 3.7%. The mean hospital stay ranged from 4.3 to 16.6 days. The mesorectal excision was described as complete in 88% cases, nearly complete in 6% and incomplete in 6%. The circumferential resection margin was negative in 95% of cases and the distal resection margin was negative in 99.7%. CONCLUSION TaTME is a feasible and reproducible technique, with good quality of oncological resection. Standardization of the technique is required with formal training. Clear indications for this procedure need to be defined and its safety further assessed in future trials.

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
BACKGROUND The aim was to compare the clinical outcomes and effectiveness of surgical treatments for haemorrhoids. METHODS Randomized clinical trials were identified by means of a systematic review. A Bayesian network meta-analysis was performed using the Markov chain Monte Carlo method in WinBUGS. RESULTS Ninety-eight trials were included with 7827 participants and 11 surgical treatments for grade III and IV haemorrhoids. Open, closed and radiofrequency haemorrhoidectomies resulted in significantly more postoperative complications than transanal haemorrhoidal dearterialization (THD), LigaSure™ and Harmonic® haemorrhoidectomies. THD had significantly less postoperative bleeding than open and stapled procedures, and resulted in significantly fewer emergency reoperations than open, closed, stapled and LigaSure™ haemorrhoidectomies. Open and closed haemorrhoidectomies resulted in more pain on postoperative day 1 than stapled, THD, LigaSure™ and Harmonic® procedures. After stapled, LigaSure™ and Harmonic® haemorrhoidectomies patients resumed normal daily activities earlier than after open and closed procedures. THD provided the earliest time to first bowel movement. The stapled and THD groups had significantly higher haemorrhoid recurrence rates than the open, closed and LigaSure™ groups. Recurrence of haemorrhoidal symptoms was more common after stapled haemorrhoidectomy than after open and LigaSure™ operations. No significant difference was identified between treatments for anal stenosis, incontinence and perianal skin tags. CONCLUSION Open and closed haemorrhoidectomies resulted in more postoperative complications and slower recovery, but fewer haemorrhoid recurrences. THD and stapled haemorrhoidectomies were associated with decreased postoperative pain and faster recovery, but higher recurrence rates. The advantages and disadvantages of each surgical treatment should be discussed with the patient before surgery to allow an informed decision to be made.

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
AIM The study aimed to define the learning curve required to gain satisfactory training to perform pelvic exenterative surgery for recurrent or locally advanced primary rectal cancer. METHOD Consecutive patients undergoing exenterative pelvic surgery for recurrent and locally advanced primary rectal cancer, by one surgical team, between 2006 and 2011 were studied. They were divided into quartiles (Q1-Q4) according to the date of surgery. A risk-adjusted cumulative sum (RA-CUSUM) model was used to evaluate the learning curve. The chi-squared test with gamma ordinal was used to assess the change with time in the four quartiles. RESULTS One hundred patients (70 males; median age 61 (25-85) years; 55 primary cancers) were included in the study. Thirty patients underwent abdominosacral resection. The number of patients who underwent plastic reconstruction (n = 53) increased from 12 in Q1 to 15 in Q4 (P = 0.781). The median operation time, intra-operative blood loss and hospital stay were 8 (3-17) h, 1.5 (0.1-17) l and 15 (9-82) days respectively. There was no significant change with time. Complete resection (R0) was achieved in 78 patients. Microscopic (R1) or macroscopic (R2) residual disease was present in 15 and seven patients respectively. The number of major complications was 20, and minor 30. RA-CUSUM analysis demonstrated an improvement in any complications after 14, in major after 12 and in minor after 25 operations. CONCLUSION Pelvic exenterative surgery for recurrent or locally advanced primary rectal cancer is complex and requires a minimum of 14 cases for an expert colorectal surgeon to gain the desirable training and experience to improve morbidity.

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
INTRODUCTION Mucinous tumours of the rectum are characterised by an abundance of extracellular mucin within the tumour complex. They are known to have a poor prognosis compared to non-mucinous adenocarcinomas. The effect of adjuvant chemotherapy on the survival outcomes of patients with mucinous cancer remains unclear. This study evaluated the 5-year overall survival of patients with mucinous rectal cancer following optimal TME surgery to determine whether adjuvant chemotherapy conferred a survival benefit. METHODS An analysis of a prospectively-maintained database was conducted of patients presenting with mucinous rectal cancer between 2000 and 2010. Patients with mucinous tumours were identified from final pathology reports of the surgical resection specimens. The primary outcome was 5-year overall survival; univariate and multivariate analysis was performed using Cox proportional hazards regression models. RESULTS A total of 191 patients were included for analysis with mean age of presentation 64.6 years (36-88 ± 11). On the fully adjusted multivariate model, EMVI status (HR 1.853, 95% CI 1.081-3.175) and not being given adjuvant chemotherapy (HR 2.888, 95% CI 1.801-4.633) were significant for disease recurrence. The 5-year overall survival for patients that had undergone adjuvant chemotherapy was 66.1% compared with 35.2% (Mantel Cox log-rank test - p < 0.0001). CONCLUSION This study demonstrates that adjuvant chemotherapy is an independent factor for improvement in overall survival in patients with mucinous adenocarcinoma. Therefore, patients who have undergone TME surgery for mucinous carcinoma of the rectum should be offered adjuvant chemotherapy even in the absence of other high-risk features for poor outcomes.

Abstract
BACKGROUND Malnutrition is prevalent in acute hospitals and malnourished patients have an increased risk of morbidity and mortality. Studies of malnutrition and quality of life (QoL) are generally limited by both the nutritional and QoL assessment methods employed. The present study aimed to evaluate the relationship between malnutrition, as assessed using a range of nutritional assessment methods, and QoL, as measured by EuroQol-5D-3L and Short-Form (SF)-36 questionnaires. METHODS The study comprised a prospective cross-sectional study of malnutrition and QoL in 149 inpatients aged 65-99 years. Exclusion criteria were: terminal illness, active malignancy, lack of capacity to consent and severe communication difficulties. Spearman's rank correlation coefficient was used to test the association between QoL indices and nutritional markers. QoL scores for those scoring above and below thresholds for nutritional risk were compared. Regression models were created to identify nutritional indices contributing to the variability of QoL. RESULTS There were significant associations between QoL scores and the Mini Nutritional Assessment (MNA)-SF. Clear differences were evident between malnourished and well-nourished patients (on the MNA-SF), those with low and normal arm muscle circumference and those with good and poor physical function. Regression analysis showed that nutritional scores and functional status made independent contributions to the prediction of QoL. The effect on food intake, mobility and psychological stress/acute disease also had a significant influence. CONCLUSIONS Malnutrition risk is linked to a poorer QoL in older people on admission to hospital. Functional status and eating-related factors are major influencers on QoL in this group. These findings reinforce the role of nutrition as a priority with respect to achieving improvements in QoL.

Abstract
In this report, we discuss a case of obscure gastrointestinal bleeding (OGIB) in an 18-year-old man, where oesophagogastroduodenoscopy (OGD) and colonoscopy proved inconclusive in determining a source of bleeding. On day 14 of admission, a laparoscopy was performed, identifying a mass 2 feet from the ileocaecal junction. This was thought initially to be a Meckel's diverticulum and the patient underwent a laparotomy and a small bowel resection. Surprisingly, the histology revealed a benign gastrointestinal stromal tumour (GIST) of the ileum, rare in such a young person. Given the diagnostic delay, we propose a simple algorithm for the diagnostic management of a teenager presenting with a significant ongoing gastrointestinal bleed.
