Laparoscopy is widely adopted across nearly all surgical subspecialties in the elective setting. Initially finding indication in minor abdominal emergencies, it has gradually become the standard approach in the majority of elective general surgery procedures. Despite many technological advances and increasing acceptance, the laparoscopic approach remains underutilized in emergency general surgery and in abdominal trauma. Emergency laparotomy continues to carry a high morbidity and mortality. In recent years, there has been a growing interest from emergency and trauma surgeons in adopting minimally invasive surgery approaches in the acute surgical setting. The present position paper, supported by the World Society of Emergency Surgery (WSES), aims to provide a review of the literature to reach a consensus on the indications and benefits of a laparoscopic-first approach in patients requiring emergency abdominal surgery for general surgery emergencies or abdominal trauma.
This position paper was developed according to the WSES methodology. A steering committee performed the literature review and drafted the position paper. An international panel of 54 experts then critically revised the manuscript and discussed it in detail, to develop a consensus on a position statement.
A total of 323 studies (systematic review and meta-analysis, randomized clinical trial, retrospective comparative cohort studies, case series) have been selected from an initial pool of 7409 studies. Evidence demonstrates several benefits of the laparoscopic approach in stable patients undergoing emergency abdominal surgery for general surgical emergencies or abdominal trauma. The selection of a stable patient seems to be of paramount importance for a safe adoption of a laparoscopic approach. In hemodynamically stable patients, the laparoscopic approach was found to be safe, feasible and effective as a therapeutic tool or helpful to identify further management steps and needs, resulting in improved outcomes, regardless of conversion. Appropriate patient selection, surgeon experience and rigorous minimally invasive surgical training, remain crucial factors to increase the adoption of laparoscopy in emergency general surgery and abdominal trauma.
The WSES expert panel suggests laparoscopy as the first approach for stable patients undergoing emergency abdominal surgery for general surgery emergencies and abdominal trauma.

Sarcopenia refers to the progressive age- or pathology-associated loss of skeletal muscle. When measured radiologically as reduced muscle mass, sarcopenia has been shown to independently predict morbidity and mortality after elective abdominal surgery. However, the European Working Group on Sarcopenia in Older People (EWGSOP) recently updated their sarcopenia definition, emphasizing both low muscle \'strength\' and \'mass\'. The aim of this systematic review and meta-analysis was to determine the prognostic impact of this updated consensus definition of sarcopenia after elective abdominal surgery.
MEDLINE, Embase, Scopus, and Cochrane Central Register of Controlled Trials (CENTRAL) databases were systematically searched for studies comparing prognostic outcomes between sarcopenic versus non-sarcopenic adults after elective abdominal surgery from inception to 15 June 2022. The primary outcomes were postoperative morbidity and mortality. Sensitivity analyses adjusting for confounding patient factors were also performed. Methodological quality assessment of studies was performed independently by two authors using the QUality in Prognosis Studies (QUIPS) tool.
Twenty articles with 5421 patients (1059 sarcopenic and 4362 non-sarcopenic) were included. Sarcopenic patients were at significantly greater risk of incurring postoperative complications, despite adjusted multivariate analysis (adjusted OR 1.56, 95 per cent c.i. 1.39 to 1.76). Sarcopenic patients also had significantly higher rates of in-hospital (OR 7.62, 95 per cent c.i. 2.86 to 20.34), 30-day (OR 3.84, 95 per cent c.i. 1.27 to 11.64), and 90-day (OR 3.73, 95 per cent c.i. 1.19 to 11.70) mortality. Sarcopenia was an independent risk factor for poorer overall survival in multivariate Cox regression analysis (adjusted HR 1.28, 95 per cent c.i. 1.13 to 1.44).
Consensus-defined sarcopenia provides important prognostic information after elective abdominal surgery and can be appropriately measured in the preoperative setting. Development of targeted exercise-based interventions that minimize sarcopenia may improve outcomes for patients who are undergoing elective abdominal surgery.

Open abdomen therapy is an effective treatment to deal with severe abdominal infections, abdominal hypertension and other critical abdominal diseases. However, this therapy is difficult to implement and has many uncertainties in the timing, manners, and follow-up treatment, which leads to the fact that open abdomen therapy is not very accessible and standardized in medical systems of China. This consensus aims to provide guiding principles for indications and implementation of open abdomen, classification methods of open abdomen wounds, technologies for abdominal closure, and management of enteroatmospheric fistula, so as to improve the accessibility and success rate of open abdomen in China.
腹腔开放疗法是处理严重腹腔感染、腹腔高压等腹部危重症的有效手段，但这一疗法实施难度高，加之腹腔开放时机和开放方式以及后续的处置和管理存在不确定性，导致这一疗法在中国医疗体系中并未普及，也不够规范。本专家共识为采取腹腔开放疗法的适应证和实施原则、腹腔开放创面的分类方法、腹腔开放后关腹措施以及肠空气瘘的处理方式等方面，提供建议和指引，从而提高中国腹腔开放疗法的可及性与成功率。.

This study aims to evaluate the clinical scenarios addressed by the EURO-2000 guidelines and the ACR appropriateness criteria for referring children to MRI and assessing the referring physician compliance with both guidelines.
In January 2022, clinical scenarios reported in the last 1000 consecutive MRI requests for children (0-16 years) in one university children\'s hospital and two general university hospitals in Belgium, Europe, were retrospectively matched to the EURO-2000 guidelines and ACR appropriateness criteria. The number of clinical scenarios addressed and the justification for MRI referral were independently assessed for both guidelines. Pooled data from the three centers were evaluated and then analyzed by center, body area and prescriber using McNemar\'s test for paired proportions and χ2-tests unpaired proportions.
After excluding incomplete or missing MRI requests, 2932 of 3000 requests were included in the analysis. Overall, out of 2932 clinical scenarios, 1229 (37.99%) were addressed by EURO-2000 and 1081 (36.37%) were addressed by the ACR appropriateness criteria (McNemar test, p = 0.12). The proportions of clinical scenarios covered by the two guidelines were statistically similar when comparing centers, but varied across body regions (p < 0.001) and referring physician specialty (p between 0.75 and 0.001). EURO-2000 guidelines provided better coverage for head and spine (p < 0.05), while the ACR appropriateness criteria provided broader coverage for abdomen, pelvis, and musculoskeletal system (p < 0.0001). For addressed clinical scenarios, prescriber compliance for both guidelines was excellent with > 94% of justified MRI examinations in all the centers.
Both the EURO-2000 guidelines and the ACR appropriateness criteria did not address two-thirds of clinical scenarios in children. Head and neck, chest and abdominal-pelvic examinations are the anatomic regions which should receive a specific attention for the future implementation of evidence-based clinical decision support tools for all referring specialists.
