RESUMO
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.

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.

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.
RESUMO
Recent advances in mesenteric anatomy have clarified the shape of the mesentery in adulthood. A key finding is the recognition of mesenteric continuity, which extends from the oesophagogastric junction to the mesorectal level. All abdominal digestive organs develop within, or on, the mesentery and in adulthood remain directly connected to the mesentery. Identification of mesenteric continuity has enabled division of the abdomen into two separate compartments. These are the mesenteric domain (upon which the abdominal digestive system is centered) and the non-mesenteric domain, which comprises the urogenital system, musculoskeletal frame, and great vessels. Given this anatomical endpoint differs significantly from conventional descriptions, a reappraisal of mesenteric developmental anatomy was recently performed. The following narrative review summarizes recent advances in abdominal embryology and mesenteric morphogenesis. It also examines the developmental basis for compartmentalizing the abdomen into two separate domains along mesenteric lines.
RESUMO
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.
RESUMO
In recent decades, surgery for rectal cancer has evolved from an operation normally performed under poor vision with a lot of blood loss, relatively high morbidity, and mortality to a safer operation. Currently, minimally invasive rectal procedures are performed with limited blood loss, reduced morbidity, and minimal mortality. The main cause is better knowledge of anatomy and adhering to the principle of operating along embryological planes. Surgery has become surgery of compartments, more so than that of organs. So, rectal cancer surgery has evolved to mesorectal cancer surgery as propagated by Heald and others. The focus on the mesentery of the rectum has led to renewed attention to the anatomy of the fascia surrounding the rectum. Better magnification during laparoscopy and improved optimal three-dimensional (3D) vision during robot-assisted surgery have contributed to the refinement of total mesorectal excision (TME). In this chapter, we describe how to perform a robot-assisted TME with particular attention to the mesentery. Specific points of focus and problem solving are discussed.
RESUMO
Over the past 5 years, systematic investigation of the mesenteric organ has expanded and shown that the mesentery is the organ in and on which all abdominal digestive organs develop and remain connected to. In turn, this observation has clarified the anatomical foundation of the abdomen and the fundamental order at that level. Findings related to the shape and development of the mesentery have illuminated its function, advancing our understanding of the pathobiology, diagnosis, and treatment of several abdominal and systemic diseases. Inclusion of the mesentery in surgical resections alters the course of benign and malignant diseases. Mesenteric-based scoring systems can enhance the radiological interpretation of abdominal disease. Emerging findings reconcile observations across scientific and clinical fields and have been assimilated into reference curricula and practice guidelines. This Review summarises the developmental, anatomical, and clinical advances made since the mesentery was redesignated as an organ in 2016.

INTRODUCTION: The mesentery is involved in Crohn's disease. The impact of the extent of mesenteric resection on postoperative disease progression in Crohn's disease remains unconfirmed. This study aimed to determine the association between resection of the mesentery and postoperative outcomes in patients with Crohn's colitis (CC) undergoing colorectal surgery. METHODS: Patients with CC who underwent colorectal resection between January 2000 and December 2018 were reviewed, and the data were gathered from a prospectively maintained database. Patients were divided into 2 groups according to the extent of mesenteric resection, the extensive mesenteric excision (EME) group and the limited mesenteric excision (LME) group. Outcomes including early postoperative morbidities and surgical recurrence were compared between the 2 groups. RESULTS: Of the 126 patients included, 60 were in the LME group and 66 in the EME group. There was no significant difference between the 2 groups in early postsurgical outcomes except the intraoperative blood loss was increased in the LME group (P = 0.002). Patients in the EME group had a longer postoperative surgical recurrence-free survival time when compared with those in the LME group (P = 0.01). LME was an independent predictor of postoperative surgical recurrence (hazard ratio 2.67, 95% confidence interval 1.04-6.85, P = 0.04). This was further confirmed in the subgroup analysis of patients undergoing colorectal resection and anastomosis (hazard ratio 2.83, 95% confidence interval 1.01-7.96, P = 0.048). DISCUSSION: In patients undergoing surgery for CC, inclusion of the mesentery is associated with similar short-term outcomes and improved long-term outcomes compared with those seen when the mesentery is retained.

Crohn's disease (CD) is a debilitating inflammatory bowel condition of unknown aetiology that is growing in prevalence globally. Large-scale studies have determined associations between female obesity or low body mass index (BMI) with risk of CD at all ages or 8- < 40 years, respectively. For males, low BMI entering adult life is associated with increased incidence of CD or ulcerative colitis up to 40 years later. Body composition analysis has shown that combinations of lean tissue loss and high visceral fat predict poor CD outcomes. Here, we assessed dietary intake, physical activity and whole or regional body composition of patients with CD relapse or remission. This anthropometric approach found people with CD, irrespective of relapse or remission, differed from a large representative healthy population sample in exhibiting elevated gynoid fat and reduced android fat. CD is associated with mesenteric adipose tissue, or "creeping fat", that envelops affected intestine exclusive of other tissue; that fat is localised to the android region of the body. In this context, CD mesenteric adiposity represents a stark juxtaposition of organ-specific and regional adiposity. Although our study population was relatively small, we suggest tentatively that there is a rationale to refer to Crohn's disease as a fatty intestine condition, akin to fatty liver conditions. We suggest that our data provide early insight into a subject that potentially warrants further investigation across a larger patient cohort.

BACKGROUND AND AIMS: Emerging evidence points to a link between creeping fat and the pathogenesis of Crohn's disease [CD]. Non-invasive assessment of the severity of creeping fat on cross-sectional imaging modality has seldom been investigated. This study aimed to develop and characterize a novel mesenteric creeping fat index [MCFI] based on computed tomography [CT] in CD patients. METHODS: MCFI was developed based on vascular findings on CT in a retrospective cohort [nâ =â 91] and validated in a prospective cohort [nâ =â 30]. The severity of creeping fat was graded based on the extent to which mesenteric fat extended around the intestinal circumference using the vessels in the fat as a marker. The accuracy of MCFI was assessed by comparing it with the degree of creeping fat observed in surgical specimens. The relationship between MCFI and fibrostenosis was characterized by determining if these correlated. The accuracy of MCFI was compared with other radiographic indices [i.e. visceral to subcutaneous fat area ratio and fibrofatty proliferation score]. RESULTS: In the retrospective cohort, MCFI had moderate accuracy in differentiating moderate-severe from mild fibrostenosis (area under the receiver operating characteristic [ROC] curve [AUC]â =â 0.799; pâ =â 0.000). ROC analysis in the retrospective cohort identified a threshold MCFI of >â 3 which accurately differentiated fibrostenosis severity in the prospective cohort [AUCâ =â 0.756; pâ =â 0.018]. An excellent correlation was shown between MCFI and the extent of fat wrapping in specimens in the prospective cohort [râ =â 0.840, pâ =â 0.000]. Neither visceral to subcutaneous fat area ratio nor fibrofatty proliferation score correlated well with the degree of intestinal fibrosis. CONCLUSIONS: MCFI can accurately characterize the extent of mesenteric fat wrapping in surgical specimens. It may become another non-invasive measure of CD fibrostenosis.

Robotic colorectal surgery is gaining popularity. The objective of this study was to compare clinical and cancer outcomes in propensity-score matched cohorts (PSM-1:1) undergoing colorectal cancer (CRC) surgery performed using laparoscopic or robotic surgery in a single institution. A PSM cohort comparison was performed in a tertiary referral cancer and National accredited rectal cancer surgery centre. Patients with CRC undergoing laparoscopic or robotic resection with curative intent from 2016 to 2019 (inclusive) were assessed for inclusion. Matched cohorts were selected using a 1:1 ratio. Statistical analysis was performed using SPSS, version 22. 128 patients were analysed [laparoscopic (n = 64); robotic (n = 64)]. Median age was 64 years (29-84 years). 55% (n = 70) of patients were male, 45% female (n = 58). SSI rates were slightly lower in the robotic group [10.9% (n = 7) v 12.5% (n = 8) p = 0.40]. Anastomotic leak rates were equal in both groups [5.4% (n = 3)]. All but one patient received an R0 resection in each group, median LNY was 14 in the robotic group and 12 in the laparoscopic group (p = 0.004) and no difference in disease recurrence (p = 0.465) or survival (p = 0.886) was observed. Structured introduction of a robotic colorectal programme over a 3-year period has resulted in equivalent outcomes with an established laparoscopic programme for CRC.

Surgical techniques have greatly changed and advanced with the advent of robot-assisted surgery (RAS). Patient outcome measures for RAS generally focus on patient morbidity and mortality, surgical complications, and hospital length of stay; there is limited research on patients' perceptions of RAS. Researchers conducted an integrative literature review of published research on patient experience and satisfaction after undergoing RAS. They searched nine databases and screened 1,263 articles for eligibility, six of which were critically appraised and synthesized into two main themes: patient satisfaction with RAS and the effect of information sharing on patient satisfaction. There was a dearth of qualitative studies exploring patients' perceptions after RAS and it was difficult to determine whether patient satisfaction was specifically related to the procedure modality (ie, robotic) or was influenced by other factors (eg, clinical outcomes). Clear differences between patient experience and satisfaction after undergoing RAS versus nonrobotic surgery are not apparent.

The mesentery is the organ in which all abdominal digestive organs develop, and which maintains these in systemic continuity in adulthood. Interest in the mesentery was rekindled by advancements of Heald and Hohenberger in colorectal surgery. Conventional descriptions hold there are multiple mesenteries centrally connected to the posterior midline. Recent advances first demonstrated that, distal to the duodenojejunal flexure, the mesentery is a continuous collection of tissues. This observation explained how the small and large intestines are centrally connected, and the anatomy of the associated peritoneal landscape. In turn it prompted recategorisation of the mesentery as an organ. Subsequent work demonstrated the mesentery remains continuous throughout development, and that abdominal digestive organs (i.e. liver, spleen, intestine and pancreas) develop either on, or in it. This relationship is retained into adulthood when abdominal digestive organs are directly connected to the mesentery (i.e. they are 'mesenteric' in embryological origin and anatomical position). Recognition of mesenteric continuity identified the mesenteric model of abdominal anatomy according to which all abdominal abdomino-pelvic organs are organised into either a mesenteric or a non-mesenteric domain. This model explains the positional anatomy of all abdominal digestive organs, and associated vasculature. Moreover, it explains the peritoneal landscape and enables differentiation of peritoneum from the mesentery. Increased scientific focus on the mesentery has identified multiple vital or specialised functions. These vary across time and in anatomical location. The following review demonstrates how recent advances related to the mesentery are re-orientating the study of human biology in general and, by extension, clinical practice.

BACKGROUND: The structures of the mesentery including adipose tissue, nerves, and lymphatics play an important role in the pathogenesis and disease progression of Crohn's disease (CD). Conventional surgical resection for CD usually does not involve resecting the mesentery en bloc with the specimen. This contrasts with complete mesocolic excision (CME) in colorectal cancer, which involves radical resection of the mesentery. Preliminary evidence from smaller studies suggests that applying the principle of mesocolic excision to CD surgery may reduce the risk of postoperative recurrence. This randomized controlled trial is designed to test whether applying the principles of mesocolic excision to CD results in reduced postoperative recurrence. It also aims to evaluate intra- and postoperative morbidity between the two approaches. METHODS: This international, multicenter, randomized controlled trial will randomize patients (n = 116) scheduled to undergo primary ileocolic resection to either receive extensive mesenteric excision (EME) or conventional ileocolic resection with limited mesenteric excision (LME). Five sites will recruit patients in three countries. In the EME group, the mesentery is resected following CME, while avoiding the root region, i.e., 1 cm from the root of the ileocolic artery and vein. In the LME group, the mesentery is retained, i.e., "close shave" or < 3 cm from the border of bowel. The primary end point will be surgical recurrence after surgery. The secondary end points will be the postoperative endoscopic and clinical recurrence, and intra- and postoperative morbidity. Demographics, risk factors, laboratory investigations, endoscopy, postoperative prophylaxis and imaging examination will be assessed. Analysis of the primary outcome will be on an intention-to-treat basis. DISCUSSION: If mesocolic excision in CD reduces postoperative disease recurrence and does not increase morbidity, this trial has the potential to change practice and reduce recurrence of CD after surgical resection.

Since the first robotic assisted surgery in 1985, the number of procedures performed annually has steadily increased. Bibliometric analysis highlights the key studies that have influenced current practice in a field of interest. We use bibliometric analysis to evaluate the 100 most cited manuscripts on robotic surgery and discuss their content and influence on the evolution of the platform. The terms 'robotic surgery,' 'robot assisted surgery' and 'robot-assisted surgery' were used to search Thomson Reuters Web of Science database for full length, English language manuscripts. The top 100 cited manuscripts were analyzed by manuscript type, surgical specialty, first and last author, institution, year and journal of publication. 14,980 manuscripts were returned. Within the top 100 cited manuscripts, the majority featured urological surgery (n = 28), followed by combined results from multiple surgical subspecialties (n = 15) and colorectal surgery (n = 13). The majority of manuscripts featured case series/reports (n = 42), followed by comparative studies (n = 24). The most cited paper authored by Nelson et al. (432 citations) reviewed technological advances in the field. The year and country with the greatest number of publications were 2009 (n = 15) and the USA (n = 68). The Johns Hopkins University published the most top 100 manuscripts (n = 18). The 100 most cited manuscripts reflect the progression of robotic surgery from a basic instrument-holding platform to today's articulated instruments with 3D technology. From feasibility studies to multicenter trials, this analysis demonstrates how robotic assisted surgery has gained acceptance in urological, colorectal, general, cardiothoracic, orthopedic, maxillofacial and neuro surgery.

BACKGROUND AND AIMS: Faecal diversion is associated with improvements in Crohn's disease but not ulcerative colitis, indicating that differing mechanisms mediate the diseases. This study aimed to investigate levels of systemic mediators of inflammation, including fibrocytes and cytokines, [1] in patients with Crohn's disease and ulcerative colitis preoperatively compared with healthy controls and [2] in patients with Crohn's disease and ulcerative colitis prior to and following faecal diversion. METHODS: Blood samples were obtained from healthy individuals and patients with Crohn's disease or ulcerative colitis. Levels of circulating fibrocytes were quantified using flow cytometric analysis and their potential relationship to risk factors of inflammatory bowel disease were determined. Levels of circulating cytokines involved in inflammation and fibrocyte recruitment and differentiation were investigated. RESULTS: Circulating fibrocytes were elevated in Crohn's disease and ulcerative colitis patients when compared with healthy controls. Smoking, or a history of smoking, was associated with increases in circulating fibrocytes in Crohn's disease, but not ulcerative colitis. Cytokines involved in fibrocyte recruitment were increased in Crohn's disease patients, whereas patients with ulcerative colitis displayed increased levels of pro-inflammatory cytokines. Faecal diversion in Crohn's disease patients resulted in decreased circulating fibrocytes, pro-inflammatory cytokines, and TGF-ß1, and increased IL-10, whereas the inverse was observed in ulcerative colitis patients. CONCLUSIONS: The clinical effect of faecal diversion in Crohn's disease and ulcerative colitis may be explained by differing circulating fibrocyte and cytokine responses. Such differences aid in understanding the disease mechanisms and suggest a new therapeutic strategy for inflammatory bowel disease.

Akkermansia muciniphila utilises colonic mucin as its substrate. Abundance is reduced in ulcerative colitis (UC), as is the relative proportion of sulphated mucin in the mucus gel layer (MGL). It is unknown if these phenomena are related, however reduced sulphated mucins could contribute to reduced abundance, owing to a lack of substrate. The aim of this study was to quantify A. muciniphila within the MGL and to relate these findings with markers of inflammation and the relative proportion of sulphomucin present. Colonic biopsies and mucus brushings were obtained from 20 patients with active UC (AC), 14 with quiescent UC (QUC) and 20 healthy controls (HC). A. muciniphila abundance was determined by RT-PCR. High iron diamine alcian-blue staining was performed for histological analysis. Patients with AC had reduced abundance of A. muciniphila compared to HC and QUC. A positive association was found between A. muciniphila abundance and higher percentage of sulphated mucin (ρ 0.546, p = 0.000). Lower abundances of A. muciniphila correlated with higher inflammatory scores (ρ = 0.294 (p = 0.001)). This study confirms an inverse relationship between A. muciniphila and inflammation and a positive association between A. muciniphila abundance and percentage of sulfated mucin in the MGL.

Peristomal skin complications are a common problem for persons with an ileostomy. PURPOSE: The purpose of this pilot study was to solicit user feedback and perform an initial assessment of the performance of a new barrier seal designed to decrease the risk of chemical-induced dermatitis. METHODS: Seven (7) potential participants who were at least 18 years of age, >6 months post surgery, with an end or loop ileostomy and unbroken peristomal skin, and who were capable of changing their appliance themselves or had the availability of care assistance were identified and recruited by the stoma care nurse at the University Hospital, Limerick, Ireland. At the initial visit and after 1 and 2 weeks, participants were asked to rate device comfort, security, and handling; skin condition was assessed by the research nurse using the Ostomy Skin Tool. Descriptive statistics were used to tabulate the results. RESULTS: Five (5) participants completed the study. Discoloration, erosion, and tissue overgrowth scores improved in 3 of 5 patients, and the mean Ostomy Skin Tool score decreased from 5.4 ± 2.19 at the initial assessment to 4 ± 1.87 at the week 2 visit. Comfort, handling, and security ratings increased from a median of 8 at the beginning of the study to 10 at week 2. CONCLUSION: Initial patient feedback regarding the new product was positive, and skin assessment results suggest the new seal may help improve peristomal skin condition. Larger studies with longer patient follow-up are needed to confirm the results of this pilot evaluation.

The aim of this study was to quantify laparoscopic instrument use and actions of both limbs during a sample of common colorectal surgical procedures. A method was devised using Observer XT software to code video recordings. Anonymised HD video recordings of nine laparoscopic colorectal procedures performed by a single surgeon were analysed. We determined the percentage and frequency of instrument use and limb actions throughout the total laparoscopic surgical duration, as well as the duration of instrument inactivity. Seven instruments and seven actions were studied across nine surgical procedures. Manoeuvring, blunt dissection, and tenting up tissues accounted for the longest amount of total surgical time (non-dominant hand (NDH) 29%, dominant hand (DH) 39%), followed by grasping (NDH 33%, DH 9%), and cauterising (NDH <0.2%, DH 8%). Least time was spent performing other actions such as suction/irrigation (NDH 0.01%, DH 3%) and stapling colorectal tissue (NDH 0.03%, DH 0.5%). The total duration of instrument use and hand actions by the dominant and non-dominant hands were similar overall. However, the frequency of actions performed was lower for the non-dominant hand. This indicates that the non-dominant hand spent more time holding actions than switching between actions, supporting the actions of the dominant hand. These findings highlight the lengthy durations of laparoscopic surgical procedures involved in navigating to anatomical planes and moving tissues. Further, the results detail the extent of secondary functions performed with the surgical instruments.
