    Abstract Recent findings related to the mesentery clarified the organisation of the abdomen at the foundational level. The Mesenteric-based model of abdominal anatomy articlulates a foundation that re-unites scientific and clinical approaches to the abdomen in health and disease. Importantly, recent advances are a reminder that we must always question dogma. The peritoneal-based dogma of conventional anatomy remained unquestioned for too long. With time, the mesenteric-based dogma will also be altered and improved on. Anatomy, and hence surgery, must always be considered as works in progress.

    Abstract Postoperative anastomotic recurrence of Crohn's disease is challenging and can lead to symptom recurrence and further surgery. The mesenteric pole of the intestine is the initial site of macroscopic anastomotic recurrence, and the mesentery may play an important role in recurrence after surgical resection. Therefore, "mesenteric-based surgery" has gained increasing attention by clinicians. However, the role of mesentery in the postoperative recurrence remains controversial. This review will examine mesenteric changes in Crohn's disease, proposed roles for mesentery in disease progression, and the potential for mesenteric-based surgery in the surgical management of Crohn disease.

    Abstract Ronan O Connell's clinical activities were fundamentally based on accurate data. His scientific outputs were based on similarly high quality data. Anybody who trained with him and in particular those who trained with him on more than occasion base their clinical and scientific activities on a similar approach. His many clinical, scientific and political achievements and accolades will be detailed in the articles in this Festschrift. There is an advancement that is important to me personally and that I would like to attribute to his influence. Exceptional and highly reproducible technique underpinned his surgery and explained the outcomes his patients experienced. Recent clarification of the anatomical basis of these techniques (the mesenteric basis) provides a unifying platform across which to reconcile human abdominal anatomy and surgery.

    Abstract Introduction: The utilisation of laparoscopic appendicectomy (LA) in children remains contentious despite the well-recognised advantages of laparoscopic surgery. The purpose of this study was to compare intraoperative and postoperative outcomes in LA and open appendicectomy (OA) when performed by adult general surgeons outside specialist paediatric practice in younger children.
    Methods: A retrospective review of all patients under the age of 13 who underwent LA for suspected appendicitis over a two-year period was conducted. These were case-matched with an equivalent number of patients who underwent OA during the same period. Intraoperative and postoperative outcomes were compared.
    Results: Fifty-one patients underwent LA during the study period. Patient demographics were statistically equivalent with the OA cohort. A statistically significant longer median operating time (58 vs 49min) was noted in the LA group, but intraoperative outcomes were otherwise comparable. LA, when compared with OA, was associated with a significant improvement in postoperative length of stay (2 vs 3 days,
    Conclusion: LA can be safely delivered by adult general surgeons to younger paediatric populations outside the setting of paediatric specialist practice, with statistically significant improvements in postoperative outcomes noted when compared with OA. These findings are of importance in the current healthcare context where adult general surgeons continue to perform the majority of paediatric appendicectomies.

    Abstract Aim: To identify and review published literature on the perceptions and experience of nurses working with RAS.
    Background: Robotic assisted surgery (RAS) is rapidly becoming accepted as the elite modality for surgery since its introduction in the 1980 s, more recently there has been a rising trend of use with several specialities operating using this technology. The role of nurses in perioperative care has been described as maintaining the momentum of the patient's journey. Patients undergoing RAS require nursing care throughout their journey, therefore knowledge of nurses' experiences and perceptions of RAS is important to identifying nurse education and development needs.
    Design: Integrative literature review DATABASE SOURCES: Databases searched for peer reviewed studies included CINAHL, Academic Search Complete, EMBASE, Scopus, ADA Psycinfo, Medline.
    Review methods: A comprehensive database search was conducted following PRISMA guidelines. Six databases were searched with 523 screened for eligibility. Ten studies were included in the review seven qualitative and three quantitative.
    Results: Ten studies were identified, critically appraised and synthesised using thematic analysis. All studies were conducted with nurses in the perioperative environment. Key findings were that nurses education regarding RAS is limited with more emphasis placed on surgeon education and training. There was evidence that nurses experienced a lack of education, training and information as barriers to their role which subsequently raised their stress levels.
    Conclusion: Evidence suggests a clear need for education and training for nurses working with RAS. In addition, nurses working with RAS provide care preoperatively, intraoperatively, postoperatively and post discharge in the community. However, no research has been conducted with nurses outside of the perioperative environment. Further research is required to understand the experiences and perceptions of nurses working with RAS patients in all care settings to identify their education and development needs.

    Abstract Background: Methylene blue staining of the resected specimen has been described as an alternative to the conventional palpation and visual inspection method to improve lymph node harvest. This meta-analysis evaluates the usefulness of this technique in surgery for rectal cancer, particularly after neoadjuvant therapy.
    Methods: Randomized controlled trials (RCTs) comparing lymph node harvest in methylene blue-stained rectal specimens to those of unstained specimens were identified from the Medline, Embase, and Cochrane databases. Non-randomized studies and those with only colonic resections were excluded. The quality of RCTs was assessed using Cochrane's risk of bias tool. A weighted mean difference (WMD) was calculated for overall harvest, harvest after neoadjuvant therapy, and metastatic nodal yield. In contrast, the risk difference (RD) was calculated to compare yields of less than 12 lymph nodes between the stained and unstained specimens.
    Results: Study selection comprised seven RCTs with 343 patients in the unstained group and 337 in the stained group. Overall lymph node harvest and harvest after neoadjuvant therapy were significantly higher in stained specimens with a WMD of 13.4 and 10.6 and a 95% confidence interval (CI) of 9.5-17.2 and 4.8-16.3, respectively. Harvest of metastatic lymph nodes was significantly higher in the stained group (WMD 1.0, 95% CI 0.6-1.4). The yield of less than 12 lymph nodes was significantly higher in the unstained group with RD of 0.292 and 95% CI of 0.182-0.403.
    Conclusion: Despite a small number of patients, this meta-analysis confirms improved lymph node harvest in surgical specimens stained with methylene blue compared with unstained specimens.

    Abstract This article summarizes the events that shaped our current understanding of the mesentery and the abdomen. The story of how this evolved is intriguing at several levels. It speaks to considerable personal commitment on the part of the pioneers involved. It explains how scientific and clinical fields went different directions with respect to anatomy and clinical practice. It demonstrates that it is no longer acceptable to adhere unquestioningly to models of abdominal anatomy and surgery. The article concludes with a brief description of the Mesenteric Model of abdominal anatomy, and of how this now presents an opportunity to unify scientific and clinical approaches to the latter.

    Abstract Fibroblast infiltration and collagen deposition result in structural changes in the bowel wall, and lead to strictures in intestinal inflammatory disease. While strictures can also occur in other contexts, such as malignancy, this review focuses on the surgical treatment of stricture secondary to inflammatory bowel disease. Distinguishing between predominantly inflammation vs established fibrosis as the cause of a stricture can be challenging. While inflammatory strictures may be responsive to medication, predominantly fibrotic strictures usually need surgical intervention. Both endoluminal and extraluminal approaches are described in this review. Endoscopic dilatation of strictures is suitable for short-segment isolated small bowel strictures. Other options are to divide the stricture surgically but preserve the length, performing a strictureplasty or resecting the strictured segment. The mesentery is increasingly recognized as playing a role in stricture recurrence. In a relapsing-remitting disease such as Crohn's disease, the preservation of intestinal length is essential and balance is needed between this and a complete resection to reduce the risk of recurrence. Pre- and postoperative involvement of the multidisciplinary team is essential to improve outcomes in this challenging clinical scenario.
