Abstract
BACKGROUND Laparoscopic vertical sleeve gastrectomy (LVSG) is now the most commonly performed bariatric procedure; however, it remains to be elucidated if it delivers equivalent long-term comorbid disease resolution outcomes similar to the longer established laparoscopic Roux-en-Y gastric bypass (LRYGB). We undertook a systematic review and meta-analysis of randomized controlled trials (RCTs) to investigate the comparative 5-year outcomes of both procedures. METHODS Electronic databases (Pubmed, EMBASE, CINAHL) were searched for RCTs conducted in adults (>18y) that compared the 5-year- outcomes of LVSG to LRYGB and described comorbidity outcomes were included. Where data allowed, effect sizes were calculated using the Hartung-Knapp-Sidik-Jonkman estimation method for random effects model. Presence of bias was assessed with Cochrane Risk of Bias 2.0 and funnel plots, and certainty of evidence evaluated by GRADE. The study prospectively registered with PROSPERO (CRD42018112054). RESULTS Three RCTs (LVSG=254, LRYGB=255) met inclusion criteria and reported on chronic disease outcomes. Improvement and/or resolution of hypertension favoured LRYGB (odds ratio 0.49, 95% CI 0.29, 0.84; P =0.03). Trends favoring LRYGB were seen for type 2 diabetes and dysplidemia, and LVSG for sleep apnea and back/joint conditions ( P >0.05). The certainty of evidence associated with each assessed outcome ranged from low to very low, in the setting of 'some' to 'high' bias assessed as being present. CONCLUSION Both LRYGB and LVSG are effective in providing long-term improvements in commonly experienced obesity-related comorbidities; however, the limited certainty of the evidence does not allow for strong clinical conclusions to be made at this time regarding benefit of one procedure over the other.

Abstract
BACKGROUND With many different operative techniques in use to reduce the incidence of incisional hernias (IH) following a midline laparotomy, there is no consensus among the clinicians on the efficacy and safety of any particular repair technique. This meta-analysis compares the prophylactic onlay mesh repair (POMR) and primary suture repair (PSR) for the incidence of IH. METHODS A meta-analysis and systematic review of MEDLINE, PubMed Central (via PubMed), Embase (via Ovid), SCOPUS, ScienceDirect, Google Scholar, SCI and Cochrane Library databases were undertaken. Seven randomized controlled trials assessing the outcomes of PSR and POMR were analyzed in accordance with the PRISMA statement. The risk of bias was assessed using the Rob2 tool. RESULTS According to the pooled analysis, POMR significantly reduced the incidence of IH compared to the PSR (OR 5.82 [95% CI 2.69, 12.58] P < 0.01) with a significantly higher seroma formation rate post-surgery (OR 0.35 [95% CI 0.18, 0.67] P < 0.01). Furthermore, the length of hospital stay (WMD -0.78 [95% CI -1.58, 0.02] P = 0.05) was significantly shorter for PSR compared to POMR group. Comparable effects were noted for reintervention, postoperative ileus, postoperative hematoma, postoperative mortality, long-term intervention and long-term deaths between the two groups. CONCLUSIONS POMR significantly reduces the risk of IH when compared to the PSR, with an increased risk of postoperative seroma formation and longer hospital stay. However, more RCTs with standardized protocols are needed for meaningful comparisons of the two interventions, along with longer duration of follow-up to assess the impact on the occurrence of IH.

Abstract
Bariatric surgery is increasingly being utilized to manage obesity and obesity related comorbidities, but may lead to the development of micronutrient deficiencies postoperatively. The anatomical, physiological, nutritional and behavioral reasons for micronutrient vulnerabilities are reviewed, along with recommendations for routine monitoring and replacement following surgery. The role the dietitian and their contribution in the postoperative identification, prevention and management of micronutrient vulnerabilities in bariatric patients is described. Specific considerations such as the nutritional and dietetic management of pregnant and lactating women post-bariatric surgery is also discussed.

Abstract
With the rapidly increasing prevalence of obesity globally, the practice of bariatric surgery is being adopted routinely to prevent the development of chronic conditions as well as some forms of cancers associated with obesity. Gastroesophageal reflux disease (GERD) is one of those chronic conditions. Furthermore, there is accumulating data that obesity is associated with complications related to longstanding GERD such as erosive esophagitis (EE), Barrett's esophagus (BE), and esophageal adenocarcinoma (EAC). Central obesity, rather than body mass index (BMI), appears to be more closely associated with these complications. It should be expected, therefore, that weight loss procedures should result in improvement in GERD symptoms and its associated complications. However, in reality the different bariatric surgical procedures have unpredictable effects on an established GERD and may even produce GERD symptoms for the very first time (de novo). In this review, we explore the literature studying the effects of bariatric surgical operations on GERD. Roux-en-Y gastric bypass appears to have the most beneficial effect on GERD. On the other hand, laparoscopic sleeve gastrectomy and laparoscopic adjustable gastric banding (LAGB) are linked with long-term increased prevalence of GERD. We argue that GERD is an extremely important preoperative consideration for any patient undergoing bariatric surgery and therefore should be thoroughly investigated objectively (with 24-hour pH study and high-resolution manometry) to select the most suitable bariatric procedure for patients for their long-term success.

Abstract
We present an interesting case of an intramucosal carcinoma (IMC) in the setting of Barrett's oesophagus in a 66-year-old woman. Her clinical course highlights the shifting paradigm in the approach to management of Barrett's oesophagus and IMC. With innovation in imaging and endoscopic treatment modalities, patients are detected earlier and managed prior to development of malignancy. The patient was treated with endoscopic modalities, and after 3 years' follow-up, she remains recurrence free.

Abstract
PURPOSE Recurrence after laparoscopic inguinal herniorrhaphy is poorly understood. Reports suggest that up to 13% of all inguinal herniorrhaphies worldwide, irrespective of the approach, are repaired for recurrence. We aim to review the risk factors responsible for these recurrences in laparoscopic mesh techniques. METHODS A search of the Medline, Embase, Science Citation Index, Current Contents and PubMed databases identified English language, peer reviewed articles on the causes of recurrence following laparoscopic mesh inguinal herniorrhaphy published between 1990 and 2018. The search terms included 'Laparoscopic methods', 'Inguinal hernia; Mesh repair', 'Recurrence', 'Causes', 'Humans'. RESULTS The literature revealed several contributing risk factors that were responsible for recurrence following laparoscopic mesh inguinal herniorrhaphy. These included modifiable and non-modifiable risk factors related to patient and surgical techniques. CONCLUSIONS Recurrence can occur at any stage following inguinal hernia surgery. Patients' risk factors such as higher BMI, smoking, diabetes and postoperative surgical site infections increase the risk of recurrence and can be modified. Amongst the surgical factors, surgeon's experience, larger mesh with better tissue overlap and careful surgical techniques to reduce the incidence of seroma or hematoma help reduce the recurrence rate. Other factors including type of mesh and fixation of mesh have not shown any difference in the incidence of recurrence. It is hoped that future randomized controlled trials will address some of these issues and initiate preoperative management strategies to modify some of these risk factors to lower the risk of recurrence following laparoscopic inguinal herniorrhaphy.

Abstract
The last 25 years have seen an increasing number of publications attesting the benefits of pharmaconutrition in the management of patients undergoing elective oncological gastrointestinal surgery. A number of randomized controlled trials and meta-analyses suggest the use of pharmaconutrition in this group of patients produces superior outcomes to standard nutritional formulations in terms of postoperative infective complications, anastomotic breakdown and length of hospital stay. The use of pharmaconutrition products, therefore, has gained increasing acceptance for use in elective gastrointestinal oncological surgical populations and been incorporated into practice guidelines. However, there remains doubts as to the robustness of such data supporting these recommendation. This is because studies reporting improved outcomes with pharmaconutrition (I) frequently compare this intervention with non-equivalent control groups; (II) do not report on the actual nutritional provision received by study participants; (III) overlook the potential impact of industry funding on research conducted and (IV) do not adopt a multi-disciplinary approach to the research undertaken. For these reasons, a critical re-appraisal of the use and recommendations of pharmaconutrition in this group of patients is urgently warranted to resolve some of the above mentioned issues. The aim of this review was to analyse meta-analyses published until the end of 2016 in this area to highlight the strengths and weakness of the present research and prioritize certain areas which will benefit from future research.

Abstract
BACKGROUND We conducted a meta-analysis of the randomized evidence to determine the relative merits of histopathological outcomes of laparoscopic assisted (LARR) versus open rectal resection (ORR) for rectal cancer. DATA SOURCES A search of PubMed and other electronic databases comparing LARR and ORR between Jan 2000 and June 2016 was performed. Histopathological variables analyzed included; location of rectal tumors; complete and incomplete TME; positive and negative circumferential resection margins (+/-CRM); positive distal resected margins (+DRM); distance of tumor from DRM; number of lymph nodes harvested; resected specimen length; tumor size and perforated rectum. RESULTS Fourteen RCTs totaling 3843 patients (LARR = 2096, ORR = 1747) were analyzed. Comparable effects were noted for all these histopathological variables except for the variable perforated rectum which favored ORR. CONCLUSIONS LARR compares favorably to ORR for rectal cancer treatment. However, there is significantly higher risk of rectal perforation during LARR compared to ORR.

Abstract
BACKGROUND This systematic review assessed feasibility and effectiveness of preoperative meal replacements to improve surgical outcomes for obese patients. METHODS PRISMA guidelines were followed and electronic databases searched for articles between January 1990 and March 2015. RESULTS Fifteen studies (942 participants including 351 controls) were included, 13 studies (n = 750) in bariatric patients. Adverse effects and dropout rates were minimal. Ten out of 14 studies achieved 5-10 % total weight loss. Six of six studies reporting liver volume achieved 10 % reduction. Endpoints for perioperative risks and outcomes were too varied to support definitive risk benefit. CONCLUSIONS Commercial meal replacements are feasible, have minimal side effects and facilitate weight loss and liver shrinkage in free-living obese patients awaiting elective surgery. A reduction in surgical risk is unclear.

Abstract
BACKGROUND Laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic vertical sleeve gastrectomy (LVSG) have been proposed as cost-effective strategies to manage obesity-related chronic disease. The aim of this meta-analysis and systematic review was to compare the "early postoperative complication rate i.e. within 30-days" reported from randomized control trials (RCTs) comparing these two procedures. METHODS RCTs comparing the early complication rates following LVSG and LRYGB between 2000 and 2015 were selected from PubMed, Medline, Embase, Science Citation Index, Current Contents, and the Cochrane database. The outcome variables analyzed included 30-day mortality, major and minor complications and interventions required for their management, length of hospital stay, readmission rates, operating time, and conversions from laparoscopic to open procedures. RESULTS Six RCTs involving a total of 695 patients (LVSG n = 347, LRYGB n = 348) reported on early major complications. A statistically significant reduction in relative odds of early major complications favoring the LVSG procedure was noted (p = 0.05). Five RCTs representing 633 patients (LVSG n = 317, LRYGB n = 316) reported early minor complications. A non-statically significant reduction in relative odds of 29 % favoring the LVSG procedure was observed for early minor complications (p = 0.4). However, other outcomes directly related to complications which included reoperation rates, readmission rate, and 30-day mortality rate showed comparable effect size for both surgical procedures. CONCLUSIONS This meta-analysis and systematic review of RCTs suggests that fewer early major and minor complications are associated with LVSG compared with LRYGB procedure. However, this does not translate into higher readmission rate, reoperation rate, or 30-day mortality for either procedure.

Abstract
BACKGROUND The prevalence of type 2 diabetes is growing in both developed and developing countries and is strongly linked with the prevalence of obesity. Bariatric surgical procedures such as laparoscopic vertical sleeve gastrectomy (LVSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB) are increasingly being utilized to manage related comorbid chronic conditions, including type 2 diabetes. METHODS A systematic review of randomized controlled trials (RCTs) was undertaken using the PRISMA guidelines to investigate the postoperative impact on diabetes resolution following LVSG versus LRYGB. RESULTS Seven RCTs involving a total of 732 patients (LVSG n = 365, LRYGB n = 367) met inclusion criteria. Significant diabetes resolution or improvement was reported with both procedures across all time points. Similarly, measures of glycemic control (HbA1C and fasting blood glucose levels) improved with both procedures, with earlier improvements noted in LRYGB that stabilized and did not differ from LVSG at 12 months postoperatively. Early improvements in measures of insulin resistance in both procedures were also noted in the studies that investigated this. CONCLUSIONS This systematic review of RCTs suggests that both LVSG and LRYGB are effective in resolving or improving preoperative type 2 diabetes in obese patients during the reported 3- to 5-year follow-up periods. However, further studies are required before longer-term outcomes can be elucidated. Areas identified that need to be addressed for future studies on this topic include longer follow-up periods, standardized definitions and time point for reporting, and financial analysis of outcomes obtained between surgical procedures to better inform procedure selection.

Abstract
INTRODUCTION To describe a case of rapidly eroded laparoscopic placed non-sutured gastric band secondary to Mycobacterium chelonae. PRESENTATION OF CASE A 65 year old male, who had undergone laparoscopic gastric banding two months prior for morbid obesity, presented to the clinic complaining of abdominal pain and night time fever of 4days duration. Urgent gastroscopy revealed eroded gastric band which was removed laparoscopically. DISCUSSION M. chelonae are not uncommon in Queensland. Although the mode of acquisition of infection remains unclear, it is suspected that human disease results from environmental exposure to dirty soil and water. The patient lives in rural Queensland and uses tank water which may be contaminated with M. chelonae. CONCLUSION It is imperative to consider environmentally acquired infection in patients with rapid erosion of non-sutured gastric band.

Abstract
Integrative veterinary medicine (IVM) describes the combination of complementary and
alternative therapies with conventional care and is guided by the best available
evidence. Veterinarians frequently encounter questions about complementary and
alternative veterinary medicine (CAVM) in practice, and the general public has
demonstrated increased interest in these areas for both human and animal health.
Consequently, veterinary students should receive adequate exposure to the principles,
theories, and current knowledge supporting or refuting such techniques. A proposed
curriculum guideline would broadly introduce students to the objective evaluation of
new veterinary treatments while increasing their preparation for responding to
questions about IVM in clinical practice. Such a course should be evidence-based,
unbiased, and unaffiliated with any particular CAVM advocacy or training group. All
IVM courses require routine updating as new information becomes available.
Controversies regarding IVM and CAVM must be addressed within the course and
throughout the entire curriculum. Instructional honesty regarding the uncertainties
in this emerging field is critical. Increased training of future veterinary
professionals in IVM may produce an openness to new ideas that characterizes the
scientific method and a willingness to pursue and incorporate evidence-based medicine
in clinical practice with all therapies, including those presently regarded as
integrative, complementary, or alternative.

Abstract
OBJECTIVES Although laparoscopic posterior fundoplication (LPF) i.e., Nissen or Toupet have the proven efficacy for controlling gastro-esophageal reflux surgically, there remain problems with postoperative dysphagia and gas bloat syndrome. To decrease some of these postoperative complications, laparoscopic anterior fundoplication (LAF) was introduced. The aim of this study was to conduct a meta-analysis and systematic review of randomized controlled trials (RCTs) to investigate the merits and drawbacks of LPF versus LAF for the treatment of gastro-esophageal reflux disease (GERD). DATA SOURCES, STUDY SELECTION, AND REVIEW METHODS A search of Medline, Embase, Science Citation Index, Current Contents, PubMed, ISI Web of Science, and the Cochrane Database identified all RCTs comparing different types of LPF and LAF published in the English Language between 1990 and 2013. The meta-analysis was prepared in accordance with the Preferred Reporting Items for Systematic reviews and Meta-analyses (PRISMA) statement. Data was extracted and analyzed on ten variables which include dysphagia score, heartburn rate, redo operative rate, operative time, overall complications, rate of conversion to open, Visick grading of satisfaction, overall satisfaction, length of hospital stay, and postoperative 24-h pH scores. DATA SYNTHESIS Nine trials totaling 840 patients (anterior = 425, posterior = 415) were analyzed. There was a significant reduction in the odds ratio for dysphagia in the LAF group compared to the LPF group. Conversely, significant reduction in the odds ratio for heartburn was observed for LPF compared to LAF. Comparable effects were noted for both groups for other variables which include redo surgery, operating time, overall complications, conversion rate, Visick's grading, patients' satisfaction, length of hospital stay, and postoperative 24-h pH scores. CONCLUSIONS Based on this meta-analysis, LPF compared to LAF is associated with significant reduction in heartburn at the expense of higher dysphagia rate on a short- and medium-term basis. We therefore conclude that LPF is a better alternative to LAF for controlling GERD symptoms.

Abstract
CONTEXT The utility of laparoscopic repair in the treatment of incisional hernia repair is still contentious. OBJECTIVES The aim was to conduct a meta-analysis of RCTs investigating the surgical and postsurgical outcomes of elective incisional hernia by open versus laparoscopic method. DATA SOURCES A search of PubMed, Medline, Embase, Science Citation Index, Current Contents, and the Cochrane Central Register of Controlled Trials published between January 1993 and September 2013 was performed using medical subject headings (MESH) "hernia," "incisional," "abdominal," "randomized/randomised controlled trial," "abdominal wall hernia," "laparoscopic repair," "open repair", "human" and "English". STUDY ELIGIBILITY CRITERIA, PARTICIPANTS AND INTERVENTIONS Prospective RCTs comparing surgical treatment of only incisional hernia (and not primary ventral hernias) using open and laparoscopic methods were selected. STUDY APPRAISAL AND SYNTHESIS METHODS Data extraction and critical appraisal were carried out independently by two authors (AA and MAM) using predefined data fields. The outcome variables analyzed included (a) hernia diameter; (b) operative time; (c) length of hospital stay; (d) overall complication rate; (e) bowel complications; (f) reoperation; (g) wound infection; (h) wound hematoma or seroma; (i) time to oral intake; (j) back to work; (k) recurrence rate; and (l) postoperative neuralgia. These outcomes were unanimously decided to be important since they influence the practical and surgical approach towards hernia management within hospitals and institutions. The quality of RCTs was assessed using Jadad's scoring system. Random effects model was used to calculate the effect size of both binary and continuous data. Heterogeneity amongst the outcome variables of these trials was determined by the Cochran Q statistic and I (2) index. The meta-analysis was prepared in accordance with PRISMA guidelines. RESULTS Sufficient data were available for the analysis of twelve clinically relevant outcomes. Statistically significant reduction in bowel complications was noted with open surgery compared to the laparoscopic repair in five studies (OR 2.56, 95 % CI 1.15, 5.72, p = 0.02). Comparable effects were noted for other variables which include hernia diameter (SMD -0.27, 95 % CI -0.77, 0.23, p = 0.29), operative time (SMD -0.08, 95 % CI -4.46, 4.30, p = 0.97), overall complications (OR -1.07, 95 % CI -0.33, 3.42, p = 0.91), wound infection (OR 0.49, 95 % CI 0.09, 2.67, p = 0.41), wound hematoma or seroma (OR 1.54, 95 % CI 0.58, 4.09, p = 0.38), reoperation rate (OR -0.32, 95 % CI 0.07, 1.43, p = 0.14), time to oral intake (SMD -0.16, 95 % CI -1.97, 2.28, p = 0.89), length of hospital stay (SMD -0.83, 95 % CI -2.22, 0.56, p = 0.24), back to work (SMD -3.14, 95 % CI -8.92, 2.64, p = 0.29), recurrence rate (OR 1.41, 95 % CI 0.81, 2.46, p = 0.23), and postoperative neuralgia (OR 0.48, 95 % CI 0.16, 1.46, p = 0.20). CONCLUSIONS On the basis of our meta-analysis, we conclude that laparoscopic and open repair of incisional hernia is comparable. A larger randomized controlled multicenter trial with strict inclusion and exclusion criteria and standardized techniques for both repairs is required to demonstrate the superiority of one technique over the other.

Abstract
Breeding records of 57 Arabian and 66 Thoroughbred mares were analysed to assess their reproductive performance under the subtropical conditions of Pakistan. The Arabian mares showed significantly higher conception rates (p<0.05) in second mated oestrus and foal heat mated oestrus compared to Thoroughbred mares. However, conception rates for first lifetime mated oestrus were similar in both breeds of mares. Age at first mating (1,301±40 vs 1,500±32 days) was significantly (p<0.05) less in Arabian compared to Thoroughbred mares. Both breeds of mares showed significantly (p<0.05) higher frequencies of oestrous cycles and conception rates during the winter (October to March) compared to summer (June to August) months. Age of mares affected the conception rates, as mares at ages 3 to 7 and 8 to 12 years of ages had significantly higher conception rates (p<0.05) than those ≥18 years old in both breeds. This study demonstrates that i) reproductive performance in Arabians is better than Thoroughbred mares under the subtropical conditions of Pakistan, ii) mares remain cyclic throughout the year and iii) conception rates were higher in mares bred during winter compared to summer months.

Abstract
Over the last 20 years there has been considerable research into the use of immunonutrition, also referred to as pharmaconutrition, in the management of patients undergoing and recovering from elective gastrointestinal surgery for malignancy. In this group of patients, the use of pharmaconutrition seems to confer superior outcomes to standard nutrition formulations with regards to postoperative infective complications and length of hospital stay. It is therefore frequently recommended for use in elective gastrointestinal oncological surgical populations. However, it remains unclear whether the data supporting these recommendation is robust. Studies reporting improved outcomes with pharmaconutrition frequently compare this intervention with non-equivalent control groups, do not report on the actual nutritional provision received by study participants, overlook the potential impact of industry funding on the conduct of research and do not adopt a multi-disciplinary approach to the research undertaken. For these reasons, an urgent critical re-appraisal of the use and recommendations of pharmaconutrition in this group of patients is warranted to resolve some of the above mentioned issues.

Abstract
BACKGROUND A meta-analysis evaluating surgical outcomes following nutritional provision provided proximal to the anastomosis within 24 hours of gastrointestinal surgery compared with traditional postoperative management was conducted. METHODS Databases were searched to identify randomized controlled trials comparing the outcomes of early and traditional postoperative feeding. Trials involving gastrointestinal tract resection followed by patients receiving nutritionally significant oral or enteral intake within 24 hours after surgery were included for analysis. RESULTS Fifteen studies involving a total of 1240 patients were analyzed. A statistically significant reduction (45%) in relative odds of total postoperative complications was seen in patients receiving early postoperative feeding (odds ratio [OR] 0.55; confidence interval [CI], 0.35 -0.87, P = .01). No effect of early feeding was seen with relation to anastomotic dehiscence (OR 0.75; CI, 0.39-1.4, P = .39), mortality (OR 0.71; CI, 0.32-1.56, P = .39), days to passage of flatus (weighted mean difference [WMD] -0.42; CI, -1.12 to 0.28, P = .23), first bowel motion (WMD -0.28; CI, -1.20 to 0.64, P = .55), or reduced length of stay (WMD -1.28; CI, -2.94 to 0.38, P = .13); however, the direction of clinical outcomes favored early feeding. Nasogastric tube reinsertion was less common in traditional feeding interventions (OR 1.48; CI, 0.93-2.35, P = .10). CONCLUSIONS Early postoperative nutrition is associated with significant reductions in total complications compared with traditional postoperative feeding practices and does not negatively affect outcomes such as mortality, anastomotic dehiscence, resumption of bowel function, or hospital length of stay.

Abstract
BACKGROUND Oesophagectomy is one of the most challenging surgeries. Potential for morbidity and mortality is high. Minimally invasive techniques have been introduced in an attempt to reduce postoperative complications and recovery times. Debate continues over whether these techniques are beneficial to morbidity and whether oncological resection is compromised. This review article will analyse the different techniques employed in minimally invasive oesophagectomy (MIO) and critically evaluate commonly reported outcome measures from the available literature. METHODS Medline, Embase, Science Citation Index, Current Contents, and PubMed databases were used to search English language articles published on MIO. Thirty-one articles underwent thorough analysis and the data were tabulated where appropriate. To date, only level III evidence exists. Where appropriate, comparisons are made with a meta-analysis on open oesophagectomy. RESULTS Positive aspects of MIO include at least comparable postoperative recovery data and oncological resection measures to open surgery. Intensive care unit requirements are lower, as is duration of inpatient stay. Respiratory morbidity varies. Negative aspects include increased technical skill of the surgeon and increased equipment requirements, increased operative time and limitation with respect to local advancement of cancer. With increasing individual experience, improvements in outcome measures and the amenability of this approach to increasing neoplastic advancement has been shown. CONCLUSION MIO has outcome measures at least as comparable to open oesophagectomy in the setting of benign and nonlocally advanced cancer. Transthoracic oesophagectomy provides superior exposure to the thoracic oesophagus compared to the transhiatal approach and is currently preferred. No multicentre randomised controlled trials exist or are likely to come into fruition. As with all surgery, careful patient selection is required for optimal results from MIO.

Abstract
Effective mentoring has an invaluable role in the development of surgeons at various levels and is frequently perceived vital in achieving career success. Its role therefore is only second to credentialing. However, the formal role of mentoring and learner support in surgical training remains non-existent. This is reflected in a paucity of empirical data on mentoring in graduate medical education which makes meaningful research even more difficult. This article reflects on these failings, explores the reasons for apathy towards mentoring in surgical training and why the attitudes toward mentoring remain casual and lukewarm. Furthermore the authors explore the literature on this subject to identify ways and methods of remedying the situation.

Abstract
BACKGROUND AND OBJECTIVES Spigelian hernia is a rare cause of incarcerated ventral abdominal hernia that may pose a diagnostic dilemma. However, with the increasing utilization of double contrast computed tomography (CT) for undiagnosed small bowel obstruction in a virgin abdomen, more such cases are being diagnosed with increasing confidence. Furthermore, with the rapid expansion of the indications for minimal access surgery in emergency situations, these rare emergencies are increasingly tackled using a laparoscopic approach leading to swift patient recovery and discharge. METHODS We present the case of an emergency intraperitoneal onlay mesh (IPOM) repair of Spigelian hernia, causing acute small bowel obstruction in a 55-year-old man with liver disease and ascites that was diagnosed using a CT scan. We conducted a search of Medline, Embase, Science Citation Index, Current Contents, PubMed, and the Cochrane Database to review the history of laparoscopic repair of Spigelian hernia and its various advancements, which are briefly presented here. RESULTS The hernia was successfully reduced using laparoscopy, revealing a moderate-size defect in the linea semilunaris. The hernial defect was repaired with a composite mesh that was tacked into position. The patient was discharged from the hospital on the second postoperative day. CONCLUSIONS Spigelian hernia in an emergency setting can be easily and swiftly repaired using the IPOM method utilizing a composite mesh.

Abstract
The purpose of this review was to examine the practice of oral assessment in postgraduate medical education in the context of the core assessment constructs of validity, reliability and fairness. Although oral assessment has a long history in the certification process of medical specialists and is a well-established part of such proceedings for a wide range of specialties in most countries, there remains concern regarding its use. Therefore, there has been some move away from oral assessment for postgraduate medical education in some countries. This review also highlights the complexity of oral assessment as an examination format, partly through a consideration of the six dimensions of oral assessment, and raises concerns about the validity, reliability and fairness of such an assessment procedure for the award of certification of completion of the specialist training. Supporting high quality published research into examination practices and outcomes and acting on the findings of such research is needed urgently to allay concerns about the transparency and fairness of these examinations, especially when assessing international medical graduates. The article concludes by proposing 15 conditions under which oral assessment is valid, reliable and fair.

Abstract
The concept of assessing competency in surgical practice is not new and has taken on an added urgency in view of the recent high-profile inquiries into "botched cases" involving surgeons of various levels in different parts of the world. Until very recently, surgeons in the United Kingdom and other parts of the world, although required to undergo formal and compulsory examinations to test their factual knowledge and decision making, were not required to demonstrate technical ability. Therefore, there existed (and still exist) no objective assessment criteria to test trainees' surgical skill, especially during the exit examination, which, if passed, provides unrestricted license to surgeons to practice their specialties. However, with the introduction of a new curriculum by various surgical societies and a demand from the lay community for better standards, new assessment tools are emerging that focus on technical competency and that could objectively and reliably measure surgical skills. Furthermore, training authorities and hospitals are keen to embrace these changes for satisfactory accreditation and reaccreditation processes and to assure the public of the safety of the public and private health care systems. In the United Kingdom, two new surgical tools (Surgical Direct Observation of Procedural Skill, and Procedure Based Assessments) have been simultaneously introduced to assess surgical trainees. The authors describe these two assessment methods, provide an overview of other assessment tools currently or previously used to assess surgical skills, critically analyze the two new assessment tools, and reflect on the merit of simultaneously introducing them.

Abstract
Malnutrition is present in the majority of patients presenting for surgical management of gastrointestinal malignancies, due to the effects of the tumour and preoperative anti-neoplastic treatments. The traditional practice of fasting patients until the resumption of bowel function threatens to further contribute to the malnutrition experienced by these patients. Furthermore, the rationale behind this traditional practice has been rendered obsolete through developments in anaesthetic agents and changes to postoperative analgesia practices. Conversely, there is a growing body of literature that consistently demonstrates that providing oral or tube feeding proximal to the anastomosis within 24 h postoperatively, is not only safe, but might be associated with significant benefits to the postoperative course. Early post operative feeding should therefore be adopted as a standard of care in oncology patients undergoing gastrointestinal resections.

Abstract
Surgical resection remains the mainstay of treatment for gastric cancer. Laparoscopic assisted gastrectomy has failed to gain universal acceptance as an alternative to the open approach for a number of reasons, one of which includes the issue of oncological radicality in terms of lymph node dissection. Nodal status, which is one of the most crucial and independent predictors of patient survival, therefore has been examined both in single institutional trials and also in randomised controlled trials especially on early gastric cancer. The issue of oncological adequacy for laparoscopic lymph node harvesting for advanced gastric cancer remains a contentious issue because of the unique challenges it poses in terms of complexity, safety and time, and also the lack of randomised controlled trials in this area. It is thus imperative that good quality multicentre randomised controlled trials are designed to investigate the benefits of extended lymphadenectomy in the setting of laparoscopic surgery, especially for advanced gastric cancer and its impact on both short and long term survival.

Abstract
Greater than 50% of patients with esophageal carcinoma are found to be incurable at the time of diagnosis, leaving only palliative options. Self-expanding metal stents (SEMs) are effective for relieving symptoms and complications associated with esophageal carcinoma and improving quality of life. We undertook a retrospective analysis to evaluate the experience of palliative esophageal stenting for symptomatic malignant dysphagia in our institution over a period of 7 years. Between January 1999 and January 2006, 126 patients who received SEMs for malignant dysphagia were identified using an upper gastrointestinal specialist nurse clinician database. Data were obtained from patient case notes, endoscopy, histopathology, radiology, and external agency databases. Of the 126 identified, 36 patients were excluded from the analysis. A number of variables including age, sex, presenting complaints, type of stent, indications of stenting, success or failure of stent insertion, survival rate, and complication rate were analyzed. Of the 90 patients, 55 (61%) were male and 35 (39%) were female. The mean age of patients was 70.79 (range 40-97) years. The predominant presenting complaints were dysphagia (n = 81) and weight loss (n = 48). The indication for stenting was worsening dysphagia in all patients. Tumors were confined to the distal esophagus and esophagogastric junction in 73 patients (81%), and the mid-esophagus in 17 (19%). Adenocarcinoma was identified in 61 patients (67.8%) and squamous cell carcinoma in 29 (32.2%). Stenting numbers were comparable in endoscopic and radiologic groups (47 vs. 43), with successful stent deployment in 89 patients. The 7- and 30-day mortality was 9% (n = 8) and 28% (n = 25), respectively. Comparable numbers of early deaths were seen in both radiologic (n = 13) and endoscopic (n = 12) groups. Causes of early inpatient death included hemorrhage (n = 5), pneumonia (n = 7), exhaustion (n = 2), cardiac causes (n = 3), perforation (n = 1), and sepsis (n = 1). The number of patients with complications was 41 (45.6%), 25 in the surgical group and 15 in the radiologic group; the difference was not significant (P = 0.13). The mean survival time was 92.5 (0-638) days and median survival time was 61 days. A subgroup of patients with complete dysphagia (score 4) gained a mean survival of 59 days. Those patients receiving adjuvant chemotherapy or radiotherapy survived significantly longer than those receiving stenting alone (152.8 days vs. 71.8 days). There is no significant difference in complications or survival when using endoscopic or radiologic methods to deploy SEMs in patients with inoperable esophageal cancer. Mortality is low; however, the morbidity rate is significant. Patients receiving adjuvant chemotherapy or radiotherapy, in addition to stenting, survived significantly longer than those with a stent only.

Abstract
The mobility, availability and persistence of heavy metals (Cd, Cr, Cu, Ni, Pb and Zn) in contaminated lake sediment samples were evaluated by means of sequential extraction scheme, proposed by the Community Bureau of Reference protocol (BCR). The metal content in the extracts was measured by atomic absorption spectrometry. The precision and accuracy of the proposed procedure were evaluated by using a certified reference material BCR 701. The maximum recoveries for heavy metals (HMs) were observed for all three steps of BCR protocol at 32h total shaking period instead of previously reported 51h, with p>0.05. The lixiviation tests (DIN 38414-S4) were used to evaluate the leaching of HMs from sediment samples and it was observed that levels of water extractable HMs were low as compared to those values obtained by acid-soluble fraction of the BCR protocol.

Abstract
Gallstone ileus (GSI) is a rare cause of mechanical small bowel obstruction. It occurs when a fistula between the gallbladder and the small bowel facilitates the migration of gallstone(s) into the small bowel. The commonest site of impaction is in the terminal ileum. We report the case of a 71-year-old female presenting with GSI diagnosed on CT scan. She was surgically explored and gallstones extracted by a simple enterotomy leading to full recovery of the patient.

Abstract
A complete breeding soundness evaluation is essential for assessment of the infertile male dog. Cryptorchidism, a sex-limited autosomal recessive trait, is more common as a unilateral condition. Azoospermia is an ejaculate consisting of seminal plasma but lacking sperm; repeated semen collections in the presence of an estrual bitch will rule out inadequate experience and lack of sexual stimulation. Both carnitine and alkaline phosphatase (AP) are produced in the epididymis; seminal plasma AP concentrations>5000 U/L indicate a normal ejaculate, whereas <5000 U/L is associated with incomplete ejaculation. Benign prostatic hypertrophy (BPH), the most common age-related condition in intact male dogs, is characterized by a sanguineous urethral discharge, hematuria, or hemospermia; diagnosis is based on prostatic enlargement and confirmed by a transabdominal biopsy. Although castration is recommended, valuable breeding dogs can be given finasteride. Prostatitis is more common in older dogs with BPH. Culture of the third fraction of the ejaculate or urine obtained by cystocentesis is indicated. Bacterial prostatitis is treated with antibiotics with high lipid solubility. Some dogs with bacterial prostatitis may develop prostatic abscesses (a medical and surgical emergency). Prostatic cysts are often asymptomatic. Approximately, 5-7% of dogs with prostatic disease have prostatic neoplasia, most commonly adenocarcinoma (it occurs in both intact and castrated dogs), which often metastasizes and has a very poor prognosis. Although a specific diagnosis can be made in many cases of male dog infertility, not all causes are amenable to treatment.

Abstract
We conducted a randomized, controlled, three-armed trial to assess whether training in syndromic management, with provision of packets, could improve the quality of STD services provided among non-formal care providers. The quality of STD case management service, observed by "incognito patients" in both intervention groups, improved substantially compared to the control group (p < 0.05). The training-and-packets group performed better in service delivery, HIV-testing referral, and condom provision when compared to the training-only group (all p < 0.05). The training-and-packets group also retained more knowledge and practiced more skillfully at six months post-intervention when compared to the training-only group (p < 0.05). Exit interviews of clients suggested that 81% of providers in the intervention groups offered advice on condom use when compared to none of those in the control group (p < 0.001). Syndromic management training and free syndrome packets for non-formal providers had a positive impact on the quality of STD care among the trained providers.

Abstract
BACKGROUND The aim was to conduct a systematic review of the literature on the subject of laparoscopic gastrectomy (LG) and determine the relative merits of laparoscopic (LG) and open gastrectomy (OG) for gastric carcinoma. MATERIAL AND METHODS A search of the Medline, Embase, Science Citation Index, Current Contents and PubMed databases identified individual retrospective and prospective series on LG (proximal, distal and total). Furthermore, all clinical trials that compared LG and OG published in the English language between January 1990 and the end of December 2006 were also identified. A large number of outcome variables were analysed for individual series and comparative trials between LG and OG and results discussed and tabulated. RESULTS The majority of the literature is published from Japan showing both oncological adequacy and safety of LG. The majority of early series and comparative studies have utilized laparoscopic resection for early and distal gastric cancer. However, with increasing advanced laparoscopic experience, advancement in digital technology and improvement in instrumentation, more advanced gastric cancers and more extensive procedures such as laparoscopic-assisted total gastrectomy and laparoscopy-assisted D2 dissection are becoming more common. To date lymph node harvesting, resection margins and complication rates seem to be equivalent to open procedures. Furthermore, the earlier fears of port-site metastases have not been borne out. CONCLUSIONS The available data suggests that LG seems to be associated with quicker return of gastrointestinal function, faster ambulation, earlier discharge from hospital, and comparable complications and recurrence rate to OG. However, the operating time for LG remains significantly longer compared to its open counterpart, although with experience it is achieving parity with OG. However, the majority of the comparative trials (if not all) probably do not have the power to detect differences in the outcome. As far as the RCT's (LG vs. OG) are concerned, the numbers of patients in such trials are small and the majority of patients were operated upon for early distal gastric cancer and, therefore, any meaningful conclusions regarding the advantages or disadvantages of LG for both the ECGs and extensive and advanced gastric tumours are difficult to justify.

Abstract
Gallstone ileus (GSI) is a rare cause of small bowel obstruction (SBO). Even more extraordinary is the spontaneous evacuation of a gallstone, which has caused SBO. A 69-year-old gentleman presented with symptoms and signs of SBO. His plain abdominal X-ray revealed dilated loops of the small bowel and opacity in the region of the terminal ileum consistent with a diagnosis of GSI. Because of severe cardiorespiratory co-morbidities, the patient was treated conservatively and improved within 24 h. A CT scan revealed that the stone had passed into the rectum and was spontaneously evacuated. If the gallstone is <2.5 cm on CT scan, spontaneous evacuation is a real possibility and initial conservative treatment in a high-risk surgical patient is a consideration.

RSH after non-contact vigorous exercise is unknown. Two such cases secondary to yoga and laughter therapy sessions, respectively, are reported. One of them required surgical intervention, whereas the other was successfully treated conservatively.

Abstract
AIM The presence of a vermiform appendix in a femoral hernia sac is termed De Garengeot hernia. It may present as a tender and/or erythematous groin swelling and is often misdiagnosed as an incarcerated or strangulated femoral hernia. The purpose of this study is to review the management of De Garengeot hernia at a single institution since 1991. MATERIALS AND METHODS A retrospective analysis of seven consecutive patients operated upon at our institution from 1991 to 2006 with De Garengeot hernia was undertaken. Patients' demographics, treatment performed and postoperative outcome were analysed. RESULTS There were three men and four women. The median age was 55 years. None of the patients were diagnosed preoperatively. The commonest presenting symptom was painful groin swelling. All patients therefore underwent emergency surgery with a presumptive diagnosis of either incarcerated or strangulated femoral hernia. Operative findings included four normal appendices, two inflamed appendices and one perforated appendix in the femoral hernial sac. Patients with normal appendix (n = 4) had mesh hernia repair without an appendicectomy. The rest of the patients (n = 3) with abnormal appendix underwent emergency open appendicectomy followed by sutured hernia repair. We had no deaths in this series and one minor wound infection. No recurrent hernia has been detected to date. CONCLUSION Inflammation of the appendix determines the type of hernia repair and surgical approach. Incidental appendicectomy in the case of a normal appendix is not preferred.

Abstract
Extraction of rectal foreign bodies is challenging. The medical literature confirms the diversity of the problem and equally some ingenious solutions, the majority of which requires either an anesthetic agent or a laparotomy to remove them. This case report presents a simple nonoperative technique to deal with one such situation.
