RESUMO
BACKGROUND: Variation exists in practice pertaining to bowel preparation before minimally invasive colorectal surgery. A survey of EAES members prioritized this topic to be addressed by a clinical practice guideline. OBJECTIVE: The aim of the study was to develop evidence-informed clinical practice recommendations on the use of bowel preparation before minimally invasive colorectal surgery, through evidence synthesis and a structured evidence-to-decision framework by an interdisciplinary panel of stakeholders. METHODS: This is a collaborative project of EAES, SAGES, and ESCP. We updated a previous systematic review and performed a network meta-analysis of interventions. We appraised the certainty of the evidence for each comparison, using the GRADE and CINeMA methods. A panel of general and colorectal surgeons, infectious diseases specialists, an anesthetist, and a patient representative discussed the evidence in the context of benefits and harms, the certainty of the evidence, acceptability, feasibility, equity, cost, and use of resources, moderated by a GIN-certified master guideline developer and chair. We developed the recommendations in a consensus meeting, followed by a modified Delphi survey. RESULTS: The panel suggests either oral antibiotics alone prior to minimally invasive right colon resection or mechanical bowel preparation (MBP) plus oral antibiotics; MBP plus oral antibiotics prior to minimally invasive left colon and sigmoid resection, and prior to minimally invasive right colon resection when there is an intention to perform intracorporeal anastomosis; and MBP plus oral antibiotics plus enema prior to minimally invasive rectal surgery (conditional recommendations); and recommends MBP plus oral antibiotics prior to minimally invasive colorectal surgery, when there is an intention to localize the lesion intraoperatively (strong recommendation). The full guideline with user-friendly decision aids is available in https://app.magicapp.org/#/guideline/LwvKej . CONCLUSION: This guideline provides recommendations on bowel preparation prior to minimally invasive colorectal surgery for different procedures, using highest methodological standards, through a structured framework informed by key stakeholders. Guideline registration number PREPARE-2023CN045.

This exploratory study was undertaken to provide an insight into issues of equality and equity that UK junior doctors perceive in relation to being able to achieve a work-life balance within educational and clinical practice. A survey with 443 junior doctors was conducted between May 2018 and September 2019. Thematic analysis of open question responses alongside correlative analyses were used to highlight issues in equity and equality faced by junior doctors. The survey revealed 77% were junior doctors in Health Education England (HEE) posts. 59% were noti n personal relationships, 60% had no children, 38% perceived the national recruitment process as helpful and 70% perceived HEE did not impact on their training. 72% had no personal barriers and 77% felt the role eas not a barrier. 1% identified no barriers. The research raised important implications for redress of equality and equity issues for all within inclusive postgraduate training in the UK.

AIM: There is a requirement for an expansive and up to date review of the management of emergency colorectal conditions seen in adults. The primary objective is to provide detailed evidence-based guidelines for the target audience of general and colorectal surgeons who are responsible for an adult population and who practise in Great Britain and Ireland. METHODS: Surgeons who are elected members of the Association of Coloproctology of Great Britain and Ireland Emergency Surgery Subcommittee were invited to contribute various sections to the guidelines. They were directed to produce a pathology-based document using literature searches that were systematic, comprehensible, transparent and reproducible. Levels of evidence were graded. Each author was asked to provide a set of recommendations which were evidence-based and unambiguous. These recommendations were submitted to the whole guideline group and scored. They were then refined and submitted to a second vote. Only those that achieved >80% consensus at level 5 (strongly agree) or level 4 (agree) after two votes were included in the guidelines. RESULTS: All aspects of care (excluding abdominal trauma) for emergency colorectal conditions have been included along with 122 recommendations for management. CONCLUSION: These guidelines provide an up to date and evidence-based summary of the current surgical knowledge in the management of emergency colorectal conditions and should serve as practical text for clinicians managing colorectal conditions in the emergency setting.

BACKGROUND: The rapid adoption of robotic surgical systems across Europe has led to a critical gap in training and credentialing for gastrointestinal (GI) surgeons. Currently, there is no existing standardised curriculum to guide robotic training, assessment and certification for GI trainees. This manuscript describes the protocol to achieve a pan-European consensus on the essential components of a comprehensive training programme for GI robotic surgery through a five-stage process. METHODS AND ANALYSIS: In Stage 1, a Steering Committee, consisting of international experts, trainees and educationalists, has been established to lead and coordinate the consensus development process. In Stage 2, a systematic review of existing multi-specialty robotic training curricula will be performed to inform the formulation of key position statements. In Stage 3, a comprehensive survey will be disseminated across Europe to capture the current state of robotic training and identify potential challenges and opportunities for improvement. In Stage 4, an international panel of GI surgeons, trainees, and robotic theatre staff will participate in a three-round Delphi process, seeking ≥ 70% agreement on crucial aspects of the training curriculum. Industry and patient representatives will be involved as external advisors throughout this process. In Stage 5, the robotic training curriculum for GI trainees will be finalised in a dedicated consensus meeting, culminating in the production of an Explanation and Elaboration (E&E) document. REGISTRATION DETAILS: The study protocol has been registered on the Open Science Framework (https://osf.io/br87d/).

Backgrounds/Aims: Thoracic epidural analgesia (TEA) is an established analgesic method in open Kausch-Whipple pancreaticoduodenectomy (KWPD). Although, it can cause hemodynamic instability and neurological complications. Inter pleural analgesia (IPA) is an alternative option. We aim to evaluate the effectiveness of IPA versus TEA after KWPD. Methods: We retrospectively studied the efficacy of IPA against TEA in patients, operated by a single surgeon. The primary outcome was the analgesic efficacy and secondary outcomes were analgesia-related complications, inotrope use, and duration. Results: Forty patients (TEA, 22; IPA, 18) were included. Both groups were well matched for patient characteristics, type, and duration of surgery. TEA was associated with higher analgesia-related complications (n = 8, 36.4% vs. n = 1, 5.6%; p = 0.027). TEA complications included analgesia not working (n = 4), leakage (n = 2), refractory hemodynamic instability (n = 1), and lower limb anaesthesia (n = 1). One patient in the IPA group encountered leakage. TEA was associated with longer inotrope requirement (35 vs. 18 hours; p = 0.047). There was no significant difference in intensive care unit (ITU) admission rate (81.8% vs. 77.8%; p > 0.999), median ITU stay (3 vs. 2 days, p = 0.385), or hospital stay (11 days in both groups). Conclusions: In open KWPD, IPA is not inferior to TEA in its efficacy of pain control. IPA was associated with less analgesia-related complications and shorter inotrope requirements. However, this was a small retrospective study. Larger randomized controlled trials are needed to study the effectiveness of IPA.
RESUMO
BACKGROUND: The impact of laparoscopic inguinal hernia repair (IHR) on chronic groin pain (CGP) prevalence, risk and daily activities compared to open IHR is still unclear. METHODS: A meta-analysis of randomised controlled trials comparing CGP rates in laparoscopic and open IHR was performed. RESULTS: 22 trials were included. CGP prevalence decreases significantly 1-2 years post-op and reaches rates as low as 4.69% (laparoscopic) and 6.91% (open) at >5 years. There is a significantly lower risk of CGP following totally extraperitoneal (TEP) than open mesh repair at all follow-up periods (p < 0.05) except for >5 years (p = 0.32). The same trend is not seen when compared to open non-mesh repair or for transabdominal pre-peritoneal repair (TAPP). There is no difference between techniques when CGP is described as moderate and/or affecting daily activities (p = 0.08). CONCLUSION: CGP rates continue to decrease at >5 years follow up. TEP consistently results in a reduction in CGP rates compared to open mesh repair however, this is not functionally significant.

INTRODUCTION: Incisional hernia has an incidence of up to 20% following laparotomy and is associated with significant morbidity and impairment of quality of life. A variety of surgical strategies including techniques and mesh types are available to manage patients with incisional hernia. Previous works have reported significant heterogeneity in outcome reporting for abdominal wall herniae, including ventral and inguinal hernia. This is coupled with under-reporting of important clinical and patient-reported outcomes. The lack of standardisation in outcome reporting contributes to reporting bias, hinders evidence synthesis and adequate data comparison between studies. This project aims to develop a core outcome set (COS) of clinically important, patient-oriented outcomes to be used to guide reporting of future research in incisional hernia. METHODS: This project has been designed as an international, multicentre, mixed-methods project. Phase I will be a systematic review of current literature to examine the current clinical and patient-reported outcomes for incisional hernia and abdominal wall reconstruction. Phase II will identify the outcomes of importance to all key stakeholders through in depth qualitative interviews. Phase III will achieve consensus on outcomes of most importance and for inclusion into a COS through a Delphi process. Phase IV will achieve consensus on the outcomes that should be included in a final COS. ETHICS AND DISSEMINATION: The adoption of this COS into clinical and academic practice will be endorsed by the American, British and European Hernia Societies. Its utilisation in future clinical research will enable appropriate data synthesis and comparison and will enable better clinical interpretation and application of the current evidence base. This study has been registered with the Core Outcome Measures in Effectiveness Trials initiative. PROSPERO REGISTRATION NUMBER: CRD42018090084.

Reciprocal specialization in interspecific interactions, such as plant-pollinator mutualisms, increases the probability that either party can have detrimental effects on the other without the interaction being dissolved. This should be particularly apparent in obligate mutualisms, such as those that exist between yucca and yucca moths. Female moths collect pollen from yucca flowers, oviposit into floral ovaries, and then pollinate those flowers. Yucca moths, which are the sole pollinators of yuccas, impose a cost in the form of seed consumption by the moth larvae. Here we ask whether there also is a genetic cost through selfish moth behavior that may lead to high levels of self fertilization in the yuccas. Historically, it has been assumed that females leave a plant immediately after collecting pollen, but few data are available. Observations of a member of the Tegeticula yuccasella complex on Yucca filamentosa revealed that females remained on the plant and oviposited in 66% of all instances after observed pollen collections, and 51% of all moths were observed to pollinate the same plant as well. Manual cross and self pollinations showed equal development and retention of fruits. Subsequent trials to assess inbreeding depression by measuring seed weight, germination date, growth rate, and plant mass at 5 months revealed significant negative effects on seed weight and germination frequency in selfed progeny arrays. Cumulative inbreeding depression was 0.475, i.e., fitness of selfed seeds was expected to be less than half that of outcrossed seeds. Single and multilocus estimates of outcrossing rates based on allozyme analyses of open-pollinated progeny arrays did not differ from 1.0. The discrepancy between high levels of behavioral self-pollination by the moths and nearly complete outcrossing in mature seeds can be explained through selective foreign pollen use by the females, or, more likely, pollen competition or selective abortion of self-pollinated flowers during early stages of fruit development. Thus, whenever the proportion of pollinated flowers exceeds the proportion that can be matured to ripe fruit based on resource availability, the potential detrimental genetic effects imposed through geitonogamous pollinations can be avoided in the plants. Because self-pollinated flowers have a lower probability of retention, selection should act on female moths to move among plants whenever moth density is high enough to trigger abortion.
RESUMO
Yucca filamentosa and its species-specific pollinator, the yucca moth, Tegeticula yuccasella (Lepidoptera: Prodoxidae), form a relationship that is often cited as a classic example of a coevolved plant-pollinator mutualism. Observations of the moth's behavior have led to predictions that moth dispersal is relatively limited and that, as a consequence, the self-compatible Y. filamentosa should experience relatively high rates of self-fertilization. In contrast, analyses of its mating system indicated that Y. filamentosa was predominantly outcrossed. To better understand effective breeding patterns in Y. filamentosa populations, 10 polymorphic allozyme loci were investigated to analyze the breeding structure of a natural Y. filamentosa population. Analyses revealed that Y. filamentosa is predominantly outcrossed, has multiply sired fruits, and that each fruit was sired by a different set of pollen donors. The effective number of pollen donors per fruit ranged from 1.56 to 3.13, indicating that some correlated mating exists within fruits. Paternity analyses revealed that pollen moved from 6 m to 293 m (mean = 118 m) within the study population and that a minimum of 10% of the progeny were sired by pollen originating outside of the population. These results are discussed in the context of the yucca-yucca moth mutualism.
