1Challenges in diagnosing mesenteric ischemia显示文摘Early identification of acute mesenteric ischemia (AMI) is challenging. The wide variability in clinical presentation challenges providers to make an early accurate diagnosis. Despite major diagnostic and treatment advances over the past decades, mortality remains high. Arterial embolus and superior mesenteric artery thrombosis are common causes of AMI. Non-occlusive causes are less common, but vasculitis may be important, especially in younger people. Because of the unclear clinical presentation and non-specific laboratory findings, low clinical suspicion may lead to loss of valuable time. During this diagnostic delay, progression of ischemia to transmural bowel infarction with peritonitis and septicemia may further worsen patient outcomes. Several diagnostic modalities are used to assess possible AMI. Multi-detector row computed tomographic angiography is the current gold standard. Although computed tomographic angiography leads to an accurate diagnosis in many cases, early detection is a persistent problem. Because early diagnosis is vital to commence treatment, new diagnostic strategies are needed. A non-invasive simple biochemical test would be ideal to increase clinical suspicion of AMI and would improve patient selection for radiographic evaluation. Thus, AMI could be diagnosed earlier with follow-up computed tomographic angiography or high spatial magnetic resonance imaging. Experimental in vitro and in vivo studies show promise for alpha glutathione S transferase and intestinal fatty acid binding protein as markers for AMI. Future research must confirm the clinical utility of these biochemical markers in the diagnosis of mesenteric ischemia.Teun C van den Heijkant Bart AC Aerts Joep A Teijink Wim A Buurman Misha DP Luyer 2013World Journal of Gastroenterology2013,19,9:31
2Strategies to reduce pulmonary complications after esophagectomy显示文摘Esophagectomy,the surgical removal of all or part of the esophagus,is a surgical procedure that is associated with high morbidity and mortality.Pulmonary complications are an especially important postoperative problem.Therefore,many perioperative strategies to prevent pulmonary complications after esophagectomy have been investigated and introduced in daily clinical practice.Here,we review these strategies,including improvement of patient performance and technical advances such as minimally invasive surgery that have been implemented in recent years.Furthermore,interventions such as methylprednisolone,neutrophil elastase inhibitor and epidural analgesia,which have been shown to reduce pulmonary complications,are discussed.Benefits of the commonly applied routine nasogastric decompression,delay of oral intake and prophylactic mechanical ventilation are unclear,and many of these strategies are also evaluated here.Finally,we will discuss recent insights and new developments aimed to improve pulmonary outcomes after esophagectomy.Teus J Weijs Jelle P Ruurda Grard AP Nieuwenhuijzen Richard van Hillegersberg Misha DP Luyer 2013World Journal of Gastroenterology2013,19,39:17
3Colorectal anastomotic leakage: Aspects of prevention, detection and treatment显示文摘All colorectal surgeons are faced from time to time with anastomotic leakage after colorectal surgery. This complication has been studied extensively without a significant reduction of incidence over the last 30 years. New techniques of prevention, by innovative anastomotic techniques should improve results in the future, but standardization and 'teachability' should be guaranteed. Risk scoring enables intra-operative decision-making whether to restore continuity or deviate. Early detection can lead to reduction in delay of diagnosis as long as a standard system is used. For treatment options, no firm evidence is available, but future studies could focus on repair and saving of the anastomosis on the one hand or anastomotical breakdown and definitive colostomy on the other hand.Freek Daams Misha Luyer Johan F Lange 2013World Journal of Gastroenterology2013,19,15:11
4Controlling postoperative ileus by vagal activation显示文摘Postoperative ileus is a frequently occurring surgical complication, leading to increased morbidity and hospital stay. Abdominal surgical interventions are known to result in a protracted cessation of bowel movement. Activation of inhibitory neural pathways by nociceptive stimuli leads to an inhibition of propulsive activity, which resolves shortly after closure of the abdomen. The subsequent formation of an inflammatory infiltrate in the muscular layers of the intestine results in a more prolonged phase of ileus. Over the last decade, clinical strategies focusing on reduction of surgical stress and promoting postoperative recovery have improved the course of postoperative ileus. Additionally, recent experimental evidence implicated antiinflammatory interventions, such as vagal stimulation, as potential targets to treat postoperative ileus and reduce the period of intestinal hypomotility. Activation of nicotinic receptors on inflammatory cells by vagal input attenuates inflammation and promotes gastrointestinal motility in experimental models of ileus. A novel physiologicalintervention to activate this neuroimmune pathway is enteral administration of lipid-rich nutrition. Perioperative administration of lipid-rich nutrition reduced manipulation-induced local inflammation of the intestine and accelerated recovery of bowel movement. The application of safe and easy to use antiinflammatory interventions, together with the current multimodal approach, could reduce postoperative ileus to an absolute minimum and shorten hospital stay.Tim Lubbers Wim Buurman Misha Luyer 2010World Journal of Gastroenterology2010,16,14:10
5Non-invasive markers of gut wall integrity in health and disease显示文摘The intestinal mucosa is responsible for the absorption of nutrients from the lumen and for the separation of the potentially toxic luminal content(external environment) from the host(internal environment).Disruption of this delicate balance at the mucosal interface is the basis for numerous(intestinal) diseases.Experimental animal studies have shown that gut wall integrity loss is involved in the development of various inflammatory syndromes,including post-operative or post-traumatic systemic inflammatory response syndrome,sepsis,and multiple organ failure.Assessment of gut wall integrity in clinical practice is still a challenge,as it is difficult to evaluate the condition of the gut non-invasively with currently available diagnostic tools.Moreover,non-invasive,rapid diagnostic means to assess intestinal condition are needed to evaluate the effects of treatment of intestinal disorders.This review provides a survey of non-invasive tests and newly identified markers that can be used to assess gut wall integrity.Joep PM Derikx Misha DP Luyer Erik Heineman Wim A Buurman 2010World Journal of Gastroenterology2010,16,42:9
6Peritoneal carcinomatosis of colorectal origin:Incidence,prognosis and treatment options显示文摘Peritoneal carcinomatosis (PC) is one manifestation of metastatic colorectal cancer (CRC). Tumor growth on intestinal surfaces and associated fluid accumulation eventually result in bowel obstruction and incapacitating levels of ascites, which profoundly affect the quality of life for affected patients. PC appears resistant to traditional 5-fluorouracil-based chemotherapy, and surgery was formerly reserved for palliative purposes only. In the absence of effective treatment, the histori-cal prognosis for these patients was extremely poor, with an invariably fatal outcome. These poor outcomes likely explain why PC secondary to CRC has received little attention from oncologic researchers. Thus, data are lacking regarding incidence, clinical disease course, and accurate treatment evaluation for patients with PC. Recently, population-based studies have revealed that PC occurs relatively frequently among patients withCRC. Risk factors for developing PC have been identi-fied:right-sided tumor, advanced T-stage, advanced N-stage, poor differentiation grade, and younger age at diagnosis. During the past decade, both chemother-apeutical and surgical treatments have achieved prom-ising results in these patients. A chance for long-term survival or even cure may now be offered to selected patients by combining radical surgical resection with intraperitoneal instillation of heated chemotherapy. This combined procedure has become known as hy-perthermic intraperitoneal chemotherapy. This edito-rial outlines recent advancements in the medical and surgical treatment of PC and reviews the most recent information on incidence and prognosis of this disease. Given recent progress, treatment should now be considered in every patient presenting with PC.Yvonne LB Klaver Valery EPP Lemmens Simon W Nienhuijs Misha DP Luyer Ignace HJT de Hingh 2012World Journal of Gastroenterology2012,18,39:9
7Challenges in diagnosing adhesive small bowel obstruction显示文摘Adhesive small bowel obstruction(ASBO)is the most frequently encountered surgical disorder of the small intestine.Up to 80%of ASBO cases resolve spontaneously and do not require invasive treatment.It is important to identify such patients that will benefit from conservative treatment in order to prevent unnecessarily exposing them to the risks associated with surgical intervention,such as morbidity and further adhesion formation.For the remaining ASBO patients,timely surgical intervention is necessary to prevent small bowel strangulation,which may cause intestinal ischemia and bowel necrosis.While early identification of these patients is key to decreasing ASBO-related morbidity and mortality,the non-specific signs and laboratory findings upon clinic presentation limit timely diagnosis and implementation of appropriate clinical management.Combining the clinical presentation findings with those from other diagnostic imaging modalities,such as abdominal X-ray,computed tomography-scan and water-soluble contrast studies,will improve diagnosis of ASBO and help clinicians to better evaluate the potential of conservative management as a safe strategy for a particular patient.Nonetheless,patients who present with moderate findings by all these approaches continue to represent a challenge.A new diagnostic strategy is urgently needed to further improve our ability to identify early signs of strangulated bowel,and this diagnostic modality should be able to indicate when surgical management is required.A number of potential serum markers have been proposed for this purpose,including intestinal fatty acid binding protein andα-glutathione S transferase.On-going research is attempting to clearly define their diagnostic utility and to optimize their potential role in determining which patients should be managed surgically.Thijs R van Oudheusden Bart AC Aerts Ignace HJT de Hingh Misha DP Luyer 2013World Journal of Gastroenterology2013,19,43:7
8良药也需遵医嘱——阳明学普及所需注意的倾向显示文摘阳明心学是治疗当今社会癌症的一剂良药,但良药也需要慎用。首先它须是真药,不能为似是而非的假药。作为空口号乃至名利手段的所谓的“阳明学”,本身就是违背阳明精神的。其次良药也有恰当的运用方式,否则不仅治不好旧病,反而有引发新病的危险。如王阳明的“知行合一”旨在克服程朱学说割裂知行的危险,但它自身却容易走向销行为知。其“心即是理”直达道德的本源,防止了程朱理学将“理”抽象化和外在化的倾向,但它自身又容易导致主观主义,过度自信。程朱理学与阳明心学应该被认作是儒学内部关于功夫修炼的两种不同的功法,它们一个是从外面去寻找道德的横向他律,通过格物致知、道问学等修身教养的功夫历程,明白普遍的理,并以此来间接地、渐进式地去发明道心,塑造自己;另一个是从个体的内心去进行道德的纵向自律,通过尊德性,直接发明自己的本心,达到顿悟。这两种功法,一种适合于普罗大众,一种更适合于利根之人。当年王阳明为程朱理学纠偏开出的药方,是有针对性的。把阳明的药说成包治百病,表面上看是在抬高阳明学,实则是对它的最大伤害。倪培民 Misha Tadd 2019孔学堂2019,6,1:5
9Diagnostic value of drain amylase for detecting intrathoracic leakage after esophagectomy显示文摘AIM:To investigate the value of elevated drain amylase concentrations for detecting anastomotic leakage(AL) after minimally invasive Ivor-Lewis esophagectomy(MIILE).METHODS:This was a retrospective analysis of prospectively collected data in two hospitals in the Netherlands. Consecutive patients undergoing MI-ILE were included. A Jackson-Pratt drain next to the dorsal side of the anastomosis and bilateral chest drains were placed at the end of the thoracoscopic procedure. Amylase levels in drain fluid were determined in all patients during at least the first four postoperative days. Contrast computed tomography scans and/or endoscopic imaging were performed in cases of a clinically suspected AL. Anastomotic leakage was defined as any sign of leakage of the esophago-gastric anastomosis on endoscopy,re-operation,radiographic investigations,post mortal examination or when gastro-intestinal contents were found in drain fluid. Receiver operator characteristic curves were used to determine the cut-off values. Sensitivity,specificity,positive predictive value,negative predictive value,risk ratio and overall test accuracy were calculated for elevated drain amylase concentrations.RESULTS:A t o t a l o f 8 9 p a t ie n t s w e re in c lu d e d between March 2013 and August 2014. No differences in group characteristics were observed between patients with and without AL,except for age. Patients with AL were older than were patients without AL(P = 0.01). One patient(1.1%) without AL died within 30 d after surgery due to pneumonia and acute respiratory distress syndrome. Anastomotic leakage that required any intervention occurred in 15 patients(16.9%). Patients with proven anastomotic leakage had higher drain amylase levels than patients without anastomotic leakage [median 384 IU/L(IQR 34-6263) vs median 37 IU/L(IQR 26-66),P = 0.003]. Optimal cut-off values on postoperative days 1,2,and 3 were 350 IU/L,200 IU/L and 160 IU/L,respectively. An elevated amylase level was found in 9 of the 15 patients with AL. Five of these 9 patients had early elevations of their amylase levels,with a median of 2 d(IQR 2-5) before signs and symptoms occurred.CONCLUSION:Measurement of drain amylase levels is an inexpensive and easy tool that may be used to screen for anastomotic leakage soon after MI-ILE. However,clinical validation of this marker is necessary.Gijs HK Berkelmans Ewout A Kouwenhoven Boudewijn JJ Smeets Teus J Weijs Luis C Silva Corten Marc J van Det Grard AP Nieuwenhuijzen Misha DP Luyer 2015World Journal of Gastroenterology2015,21,30:3

12Learning curves in minimally invasive esophagectomy显示文摘Surgical innovation and pioneering are important for improving patient outcome, but can be associated with learning curves. Although learning curves in surgery are a recognized problem, the impact of surgical learning curves is increasing, due to increasing complexity of innovative surgical procedures, the rapid rate at which new interventions are implemented and a decrease in relative effectiveness of new interventions compared to old interventions. For minimally invasive esophagectomy(MIE), there is now robust evidence that implementation can lead to significant learning associated morbidity(morbidity during a learning curve, that could have been avoided if patients were operated by surgeons that have completed the learning curve). This article provides an overview of the evidence of the impact of learning curves after implementation of MIE. In addition, caveats for implementation and available evidence regarding factors that are important for safe implementation and safe pioneering of MIE are discussed.Frans van Workum Laura Fransen Misha DP Luyer Camiel Rosman 2018World Journal of Gastroenterology2018,24,44:2

14X-ray imaging of 30 year old wine grape wood reveals cumulative impacts of rootstocks on scion secondary growth and Ravaz index显示文摘Annual rings from 30 year old vines in a California rootstock trial were measured to determine the effects of 15 different rootstocks on Chardonnay and Cabernet Sauvignon scions.Viticultural traits measuring vegetative growth,yield,berry quality,and nutrient uptake were collected at the beginning(1995 to 1999)and end(2017 to 2020)of the lifetime of a vineyard initially planted in 1991 and removed in 2021.X-ray Computed Tomography(CT)was used to measure ring widths in 103 vines.Ring width was modeled as a function of ring number using a negative exponential model.Early and late wood ring widths,cambium width,and scion trunk radius were correlated with 27 traits.Modeling of annual ring width shows that scions alter the width of the first rings but that rootstocks alter the decay of later rings,consistently shortening ring width throughout the lifetime of the vine.Ravaz index,juice pH,photosynthetic assimilation and transpiration rates,and instantaneous water use efficiency are correlated with scion trunk radius.Ultimately,our research indicates that rootstocks modulate secondary growth over years,altering physiology and agronomic traits.Rootstocks act in similar but distinct ways from climate to modulate ring width,which borrowing techniques from dendrochronology,can be used to monitor both genetic and environmental effects in woody perennial crop species.ZoëMigicovsky Michelle Y.Quigley Joey Mullins Tahira Ali Joel F.Swift Anita Rose Agasaveeran Joseph D.Dougherty Brendan Michael Grant Ilayda Korkmaz Maneesh Reddy Malpeddi Emily L.McNichol Andrew W.Sharp Jackie L.Harris Danielle R.Hopkins Lindsay M.Jordan Misha T.Kwasniewski R.Keith Striegler Asia L.Dowtin Stephanie Stotts Peter Cousins Daniel H.Chitwood 2023Horticulture Research2023,10,1:1
