| 1 | Enhanced recovery after surgery programs hasten recovery after colorectal resections显示文摘Colorectal resection was traditionally associated with significant morbidity and prolonged stay in hospital.Laparoscopic colorectal resection was first described in 1991 as a minimally invasive form of colorectal surgery.It was later on assessed by multiple randomized controlled trials and meta-analysis and was found to be associated with a faster recovery,lower complication rates and a shorter stay in hospital compared with open resection.To assess the effect of enhanced recovery after surgery (ERAS) program on postoperative length of stay after elective colorectal resections,a literature review was conducted,supplemented by the results of 111 ERAS colorectal resections at regional NWS Hospital using a protocol based on the Fast Track approach described by Kehlet in 1999.ERAS has been shown to improve postoperative recovery,reduce length of stay and enhance early return to normal function when compared with traditional colorectal surgical protocols.The role of laparoscopic surgery in colorectal resections within a fast-track (ERAS) program is controversial.The current evidence suggests that within such a program,there is no difference between laparoscopic and open colorectal surgery in terms of postoperative recovery rates or length of hospital stay. | Ned Abraham Sinan Albayati | 2011 | World Journal of Gastrointestinal Surgery2011，3，1： | 56 |
| 2 | Enhanced recovery after surgery with laparoscopic radical gastrectomy for stomach carcinomas显示文摘AIM: To study the efficacy of the enhanced recovery after surgery(ERAS) program in laparoscopic radical gastrectomy for stomach carcinomas.METHODS: From June 2010 to December 2012, 61 gastric cancer patients who underwent laparoscopicassisted radical gastrectomy with D2 lymphadenectomy at First Hospital of Jilin University were enrolled in this randomized controlled trial.(Clinical Trials.gov, registration ID: NCT01955096). The subjects were divided into the ERAS program group and the conventional control group. The clinical characteristics, recovery variables, and complications of patients were analyzed.RESULTS: The time to first ambulation, oral food intake, and time to defecation were significantly shorter in the ERAS group(n = 30), compared to the conventional group(n = 31; P = 0.04, 0.003, and 0.01, respectively). The postoperative hospital stay was less in the ERAS group(6.8 ± 1.1 d) compared to the conventional group(7.7 ± 1.1 d)(P = 0.002). There was no significant difference in postoperative complications between the ERAS(1/30) and conventional care groups(2/31)(P = 1.00). There were no readmissions or mortality during the 30-d follow-up period.CONCLUSION: The ERAS program is associated with a shorter hospital stay in gastric cancer patients undergoing laparoscopic radical gastrectomy. The ERAS protocol is useful in the treatment of gastric cancer. | Ikram Abdikarim Xue-Yuan Cao Shou-Zhen Li Yin-Quan Zhao Yerlan Taupyk Quan Wang | 2015 | World Journal of Gastroenterology2015，21，47： | 39 |
| 3 | Enhanced recovery after surgery programs in patients undergoing hepatectomy:A meta-analysis显示文摘AIM:To evaluate the impact of enhanced recovery after surgery(ERAS) programs in comparison with traditional care on liver surgery outcomes.METHODS:The Pub Med,EMBASE,CNKI and Cochrane Central Register of Controlled Trials databases were searched for randomized controlled trials(RCTs) comparing the ERAS program with traditional care in patients undergoing liver surgery. Studies selected for the meta-analysis met all of the following inclusion criteria:(1) evaluation of ERAS in comparison to traditional care in adult patients undergoing elective open or laparoscopic liver surgery;(2) outcome measures including complications,recovery of bowel function,and hospital length of stay; and(3) RCTs. The following exclusion criteria were applied:(1) the study was not an RCT;(2) the study did not compare ERAS with traditional care;(3) the study reported on emergency,non-elective or transplantation surgery; and(4) the study consisted of unpublished studies with only the abstract presented at a national or international meeting. The primary outcomes were complications. Secondary outcomes were length of hospital stay and time to first flatus.RESULTS:Five RCTs containing 723 patients were included in the meta-analysis. In 10/723 cases,patients presented with benign diseases,while the remaining 713 cases had liver cancer. Of the five studies,three were published in English and two were published in Chinese. Three hundred and fifty-four patients were in the ERAS group,while 369 patients were in the traditional care group. Compared with traditional care,ERAS programs were associated with significantly decreased overall complications(RR = 0.66; 95%CI:0.49-0.88; P = 0.005),grade?Ⅰ?complications(RR = 0.51; 95%CI:0.33-0.79; P = 0.003),and hospitallength of stay [WMD =-2.77 d,95%CI:-3.87-(-1.66); P < 0.00001]. Similarly,ERAS programs were associated with decreased time to first flatus [WMD =-19.69 h,95%CI:-34.63-(-4.74); P < 0.0001]. There was no statistically significant difference in grade Ⅱ-Ⅴ complications between the two groups.CONCLUSION:ERAS is a safe and effective program in liver surgery. Future studies should define the active elements to optimize postoperative outcomes for liver surgery. | Tian-Gen Ni Han-Teng Yang Hao Zhang Hai-Peng Meng Bo Li | 2015 | World Journal of Gastroenterology2015，21，30： | 34 |
| 4 | Introducing an enhanced recovery after surgery program in colorectal surgery:A single center experience显示文摘AIM:To study the implementation of an enhanced recovery after surgery(ERAS)program at a large University Hospital from'pilot study'to'standard of care'.METHODS:The study was designed as a prospective single centre cohort study.A prospective evaluation of compliance to a protocol based on full application of all ERAS principles,through the progressive steps of its implementation,was performed.Results achieved in the initial pilot study conducted by a dedicated team(n=47)were compared to those achieved in the shared protocol phase(n=143)three years later.Outcomes were length of postoperative hospital stay,readmission rate,compliance to the protocol and morbidity.Primary endpoint was the description of the results and the identification of critical issues of large scale implementation of an ERAS program in colorectal surgery emerged in the experience of a single center.Secondary endpoint was the identification of interventions that have been proven to be effective for facilitating the transition from traditional care pathways to a multimodal management protocol according to ERAS principles in colorectal surgery at a single center.RESULTS:During the initial pilot study(March 2009 to December 2010;47 patients)conducted by a dedicated multidisciplinary team,compliance to the items of ERAS protocol was 93%,with a median length of hospital stay(LOS)of 3 d.Early anastomotic fistulas were observed in 2 cases(4.2%),which required reoperation(Clavien-Dindo gradeⅢb).None of the patients had been discharged before the onset of the complication,which could therefore receive prompt treatment.There were also four(8.5%)minor complications(ClavienDindo gradeⅡ).Thirty days readmission rate was 4%.Perioperative mortality was nil.After implementation of the protocol throughout the Hospital in unselected patients(May 2012 to December 2012;147 patients)compliance was 74%,with a median LOS of 6 d.Early anastomotic fistulas were observed in 11 cases(7.7%),5(3.5%)of which required reoperation(Clavien-Dindo gradeⅢb).Two early anastomotic fistulas were treated by radiologic/endoscopic manoeuvres and 4 were treated conservatively.There were also 36(25.2%)minor complications,21(14.7%)of which were Clavien-Dindo gradeⅡand 15(10.5%)of which were Clavien-Dindo gradeⅠ.Only two patients whose course was adversely affected by the development of an anastomotic leak had been discharged before the onset of the complication itself,requiring readmission.Readmission rate within 30 d was 4%.Perioperative mortality was 1%.CONCLUSION:Our results confirm that introduction of an ERAS protocol for colorectal surgery allows quickerpostoperative recovery and shortens the length of stay compared to historical series. | Stefano Bona Mattia Molteni Riccardo Rosati Ugo Elmore Pietro Bagnoli Roberta Monzani Monica Caravaca Marco Montorsi | 2014 | World Journal of Gastroenterology2014，20，46： | 30 |
| 5 | Colorectal cancer:Current imaging methods and future perspectives for the diagnosis, staging and therapeutic response evaluation显示文摘In the last 10 years the mortality rate of colorectal cancer(CRC)has decreased by more than 20%due to the rising developments in diagnostic techniques and optimization of surgical,neoadjuvant and palliative therapies.Diagnostic methods currently used in the evaluation of CRC are heterogeneous and can vary within the countries and the institutions.This article aims to discuss in depth currently applied imaging modalities such as virtual computed tomography colonoscopy,endorectal ultrasound,computed tomography(CT)and magnetic resonance imaging(MRI)in the diagnosis of CRC.Special focus is put on the potential of recent diagnostic developments as diffusion weighted imaging MRI,MRI biomarkers(dynamic enhanced MRI),positron emission tomography with 2-(fluorine-18)-fluoro-2-deoxy-D-glucose(FDG-PET)combined with computed tomography(PET/CT)and new hepatobiliary MRI contrast agents.The precise role,advantage and disadvantages of these modalities are evaluated controversially in local staging,metastatic spread and treatment monitoring of CRC.Finally,the authors will touch upon the future perspectives in functional imaging evaluating the role of integrated FDG-PET/CT with perfusion CT,MRI spectroscopy of primary CRC and hepatic transit time analysis using contrast enhanced ultrasound and MRI in the detection of liver metastases.Validation of these newer imaging techniques may lead to significant improvements in the management of patients with colorectal cancer. | Maka Kekelidze Luigia D'Errico Michele Pansini Anthony Tyndall Joachim Hohmann | 2013 | World Journal of Gastroenterology2013，19，46： | 28 |
| 6 | value of contrast-enhanced ultrasound in the differential diagnosis of gallbladder lesion显示文摘AIM To describe contrast-enhanced ultrasound(CEUS) features and evaluate differential diagnosis value of CEUS and conventional ultrasound for patients with benign and malignant gallbladder lesions. METHODS This study included 105 gallbladder lesions. Before surgical resection and pathological examination, conventional ultrasound and CEUS were performed to examine for lesions. Then, all the lesions were diagnosed as(1) benign,(2) probably benign,(3) probably malignant or(4) malignant using both conventional ultrasound and CEUS. The CEUS features of these gallbladder lesions were analyzed and diagnostic efficiency between conventional ultrasound and CEUS was compared.RESULTS There were total 17 cases of gallbladder cancer and 88 cases of benign lesion. Some gallbladder lesions had typical characteristics on CEUS(e.g., gallbladder adenomyomatosis had typical characteristics of small nonenhanced areas on CEUS). The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of CEUS were 94.1%, 95.5%, 80.0%, 98.8%and 95.2%, respectively. These were significantly higher than conventional ultrasound(82.4%, 89.8%, 60.9%, 96.3% and 88.6%, respectively). CEUS had an accuracy of 100% for gallbladder sludge and CEUS helped in differential diagnosis among gallbladder polyps, gallbladder adenoma and gallbladder cancer.CONCLUSION CEUS may provide more useful information and improve the diagnosis efficiency for the diagnosis of gallbladder lesions than conventional ultrasound. | Hui-Ping Zhang Min Bai Ji-Ying Gu Ying-Qian He Xiao-Hui Qiao Lian-Fang Du | 2018 | World Journal of Gastroenterology2018，24，6： | 27 |
| 7 | Fast-track rehabilitation vs conventional care in laparoscopic colorectal resection for colorectal malignancy: A meta-analysis显示文摘AIM:To evaluate the fast-track rehabilitation protocol and laparoscopic surgery(LFT)vs conventional care strategies and laparoscopic surgery(LCC).METHODS:Studies and relevant literature comparing the effects of LFT and LCC for colorectal malignancy were identified in MEDLINE,the Cochrane Central Register of Controlled Trials and EMBASE.The complications and re-admission after approximately 1 mo were assessed.RESULTS:Six recent randomized controlled trials(RCTs)were included in this meta-analysis,which related to 655 enrolled patients.These studies demonstrated that compared with LCC,LFT has fewer complications and a similar incidence of re-admission after approximately 1 mo.LFT had a pooled RR of 0.60(95%CI:0.46-0.79,P<0.001)compared with a pooled RR of 0.69(95%CI:0.34-1.40,P>0.5)for LCC.CONCLUSION:LFT for colorectal malignancy is safe and efficacious.Larger prospective RCTs should be conducted to further compare the efficacy and safety of this approach. | Ping Li Fang Fang Jia-Xun Cai Dong Tang Qing-Guo Li Dao-Rong Wang | 2013 | World Journal of Gastroenterology2013，19，47： | 26 |
| 8 | Enhanced recovery after surgery protocols in functional endoscopic sinus surgery for patients with chronic rhinosinusitis with nasal polyps: a randomized clinical trial显示文摘Background:Enhanced recovery after surgery (ERAS) protocols are a series of perioperative care to optimize preoperative preparation, prevent postoperative complications, minimize stress, and speed up recovery. This study aimed to assess the impact of ERAS protocols for functional endoscopic sinus surgery (FESS) in patients with chronic rhinosinusitis with nasal polyps (CRSwNP).Methods:One hundred and two patients with CRSwNP undergoing FESS were randomly divided into the ERAS group and the control group. The outcomes of the Self-Rating Anxiety Scale (SAS), Visual Analogue Scale (VAS), Medical Outcomes Study Sleep Scale (MOS-SS) and Kolcaba Comfort Scale Questionnaire (GCQ) were determined in both groups. The serum levels of C-reactive protein (CRP) were compared preoperatively and 24 hours postoperatively.Results:The ERAS group had a significantly better SAS scores than did the control group (28 [24, 35] vs. 43 [42, 47], Z=5.968, P<0.001). The rhinalgia and headache scores at 2, 24 and 48 hours postoperatively were lower in the ERAS group than that in the control group (all P < 0.001). The outcomes of the MOS-SS (43 [42, 39] vs. 28 [22, 35], Z= 7.071, P < 0.001) and GCQ (76 [68, 87] vs. 64 [50, 75], Z= 4.806, P < 0.001) were significantly different between the two groups. No significant difference was found in the preoperative CRP levels between the two groups (1.3 [0.6, 2.8] vs. 0.5 [0.5, 1.2], Z = 3.049, P > 0.05);However, the CRP level in 24 hours postoperatively was significantly lower in the ERAS group than that in the control group (2.5 [1.4, 3.9] vs. 6.6 [3.8, 9.0], Z = 5.027, P < 0.001). The incidence rates of complications, such as nausea/emesis (χ^2=0.343, P>0.05), hemorrhage, aspiration and tumble, were not increased in the ERAS group compared with those in the control group. The ERAS group had a significantly shorter length of hospital stay (5 [4, 5] days vs. 8 [8,9] days, Z=8.939, P<0.001) and hospitalization expenses ($ 2670 [2375, 2740] vs. $3129 [3116, 3456], Z=8.514, P<0.001).Conclusions:ERAS protocols might optimize FESS for patients with CRSwNP by reducing psychological and physical stress, shortening the length of hospital stay and lowering hospitalization expenses without increasing postoperative complications. | Xi-Fu Wu Wei-Feng Kong Wei-Hao Wang Lian-Xiong Yuan Hui-Qing Xu Min Qi Shao-Li Zhou Qin-Tai Yang | 2019 | Chinese Medical Journal2019，，3： | 26 |

| 10 | Enhanced recovery program is safe and improves postoperative insulin resistance in gastrectomy显示文摘AIM: To assess the safety of enhanced recovery after surgery(ERAS) program in gastrectomy and influences on nutrition state and insulin-resistance. METHODS: Our ERAS program involved shortening the fasting periods and preoperative carbohydrate loading. Eighty gastrectomy patients were randomly assigned to either the conventional group(CG) or ERAS group(EG). We assessed the clinical characteristics and postoperative outcomes prospectively. The primary endpoint was noninferiority in timely discharge from the hospital within 12 d. Secondary endpoints were the incidence of aspiration at anesthesia induction, incidence of postoperative complications, health related quality of life(HRQOL) using the SF8 Health Survey questionnaire, nutrition state [e.g., albumin, transthyretin(TTR), retinal-binding protein(RBP), and transferrin(Tf)], the homeostasis model assessment-insulin resistance(HOMA-R) index, postoperative urine volume,postoperative weight change, and postoperative oral intake.RESULTS: The ERAS program was noninferior to the conventional program in achieving discharge from the hospital within 12 d(95.0% vs 92.5% respectively; 95%CI:-10.0%-16.0%). There was no significant difference in postoperative morbidity between the two groups. Adverse events such as vomiting and aspiration associated with the induction of general anesthesia were not observed. There were no significant differences with respect to postoperative urine volume, weight change, and oral intake between the two groups. EG patients with preoperative HOMA-R scores above 2.5 experienced significant attenuation of their HOMA-R scores on postoperative day 1 compared to CG patients(P = 0.014). There were no significant differences with respect to rapid turnover proteins(TTR, RBP and Tf) or HRQOL scores using the SF8 method.CONCLUSION: Applying the ERAS program to patients who undergo gastrectomy is safe, and improves insulin resistance with no deterioration in QOL. | Nobuaki Fujikuni Kazuaki Tanabe Noriaki Tokumoto Takahisa Suzuki Minoru Hattori Toshihiro Misumi Hideki Ohdan | 2016 | World Journal of Gastrointestinal Surgery2016，8，5： | 23 |
| 11 | Application value of enhanced recovery after surgery for total laparoscopic uncut Roux-en-Y gastrojejunostomy after distal gastrectomy显示文摘AIM To evaluate the safety and feasibility of enhanced recovery after surgery(ERAS) for total laparoscopic uncut Roux-en-Y gastrojejunostomy after distal gastrectomy.METHODS The clinical data of 42 patients who were divided into an ERAS group(n = 20) and a control group(n = 22) were collected. The observed indicators included operation conditions, postoperative clinical indexes, and postoperative serum stress indexes. Measurement data following a normal distribution are presented as mean ± SD and were analyzed by t-test. Count data were analyzed by χ~2 test.RESULTS The operative time, volume of intraoperative blood loss, and number of patients with conversion to opensurgery were not significantly different between the two groups. Postoperative clinical indexes, including the time to initial anal exhaust, time to initial liquid diet intake, time to out-of-bed activity, and duration of hospital stay of patients without complications, were significantly different between the two groups(t = 2.045, 8.685, 2.580, and 4.650, respectively, P < 0.05 for all). However, the time to initial defecation, time to abdominal drainage-tube removal, and the early postoperative complications were not significantly different between the two groups. Regarding postoperative complications, on the first and third days after the operation, the white blood cell count(WBC) and C reactive protein(CRP) and interleukin-6(IL-6) levels in the ERAS group were significantly lower than those in the control group.CONCLUSION The perioperative ERAS program for total laparoscopic uncut Roux-en-Y gastrojejunostomy after distal gastrectomy is safe and effective and should be popularized. Additionally, this program can also reduce the duration of hospital stay and improve the degree of comfort and satisfaction of patients. | Yi-Feng Zang Feng-Zhou Li Zhi-Peng Ji Yin-Lu Ding | 2018 | World Journal of Gastroenterology2018，24，4： | 23 |
| 12 | Application of enhanced recovery after gastric cancer surgery: An updated meta-analysis显示文摘AIM To provide an updated assessment of the safety and efficacy of enhanced recovery after surgery(ERAS) protocols in elective gastric cancer(GC) surgery.METHODS Pub Med, Medline, EMBASE, World Health Organization International Trial Register, and Cochrane Library were searched up to June 2017 for all available randomized controlled trials(RCTs) comparing ERAS protocols and standard care(SC) in GC surgery. Thirteen RCTs, with a total of 1092 participants, were analyzed in this study, of whom 545 underwent ERAS protocols and 547 received SC treatment.RESULTS No significant difference was observed between ERAS and control groups regarding total complications(P = 0.88), mortality(P = 0.50) and reoperation(P = 0.49). The incidence of pulmonary infection was significantly reduced(P = 0.03) following gastrectomy. However, the readmission rate after GC surgery nearly tripled under ERAS(P = 0.009). ERAS protocols significantly decreased the length of postoperative hospital stay(P < 0.00001) and medical costs(P < 0.00001), and accelerated bowel function recovery, as measured by earlier time to the first flatus(P = 0.0004) and the first defecation(P < 0.0001). Moreover, ERAS protocols were associated with a lower level of serum inflammatory response, higher serum albumin, and superior shortterm quality of life(QOL).CONCLUSION Collectively, ERAS results in accelerated convalescence, reduction of surgical stress and medical costs, improved nutritional status, and better QOL for GC patients. However, high-quality multicenter RCTs with large samples and long-term follow-up are needed to more precisely evaluate ERAS in radical gastrectomy. | Liu-Hua Wang Ren-Fei Zhu Cheng Gao Shou-Lin Wang Li-Zong Shen | 2018 | World Journal of Gastroenterology2018，24，14： | 22 |
| 13 | Contrast-enhanced ultrasound of histologically proven hepatic epithelioid hemangioendothelioma显示文摘AIM: To analyze contrast-enhanced ultrasound(CEUS) features of histologically proven hepatic epithelioid hemangioendothelioma(HEHE) in comparison to other multilocular benign focal liver lesions(FLL).METHODS: Twenty-five patients with histologically proven HEHE and 45 patients with histologically proven multilocular benign FLL were retrospectively reviewed. Four radiologists assessed the CEUS enhancement pattern in consensus.RESULTS: HEHE manifested as a single(n = 3) or multinodular(n = 22) FLL. On CEUS, HEHE showed rim-like(18/25, 72%) or heterogeneous hyperenhancement(7/25, 28%) in the arterial phase and hypoenhancement(25/25, 100%) in the portal venous and late phases(PVLP), a sign of malignancy. Eighteen patients showed central unenhanced areas(18/25, 72%); in seven patients(7/25, 28%), more lesions were detected in the PVLP. In contrast, all patients with hemangioma and focal nodular hyperplasia showed hyperenhancement as the most distinctive feature(P < 0.01).CONCLUSION: CEUS allows for characterization of unequivocal FLL. By analyzing the hypoenhancement in the PVLP, CEUS can determine the malignant nature of HEHE. | Yi Dong Wen-Ping Wang Vito Cantisani Mirko D'Onofrio Andre Ignee Lorenzo Mulazzani Adrian Saftoiu Zeno Sparchez Ioan Sporea Christoph F Dietrich | 2016 | World Journal of Gastroenterology2016，22，19： | 21 |
| 14 | Constructal optimization of twice Y-shaped assemblies of fins by taking maximum thermal resistance minimization as objective显示文摘In this paper,constructal optimization of the twice Y-shaped assemblies of fins with six freedom degrees (characteristic parameters of geometry) is performed by employing finite element method and taking dimensionless maximum thermal resistance as a performance index,and the heat transfer performance of the twice Y-shaped assemblies of fins under various conditions with different freedom degrees are analyzed. The results show that the twice assemblies can improve the heat transfer performance of Y-shaped fin remarkably,and the minimum maximum thermal resistance of the twice Y-shaped assemblies of fins decreases by 36.37% compared with that of once Y-shaped assembly of fins. It is also proved again that the larger the number of freedom degrees for evolving is,the more perfect the system performance is. The effects of different characteristic parameters of geometry on the performance of the twice Y-shaped assemblies of fins are different,one should pay different attention to these parameters in practical engineering designs. The effects of two angles on the maximum thermal resistance are larger,but the optima of the two angles are robust. The effects of two height ratios on the maximum thermal resistance are more remarkable than those of two thickness ratios. | XIE ZhiHui, CHEN LinGen & SUN FengRui Postgraduate School, Naval University of Engineering, Wuhan 430033, China | 2010 | Science China(Technological Sciences)2010，53，10： | 21 |

| 16 | Impact of enhanced recovery after surgery programs on pancreatic surgery:A meta-analysis显示文摘AIM To evaluate the impact of enhanced recovery after surgery(ERAS) programs on postoperative complications of pancreatic surgery. METHODS Computer searches were performed in databases(including PubM ed, Cochrane Library and Embase) for randomized controlled trials or case-control studies describing ERAS programs in patients undergoing pancreatic surgery published between January 1995 and August 2017. Two researchers independently evaluated the quality of the studies' extracted data that met the inclusion criteria and performed a metaanalysis using Rev Man5.3.5 software. Forest plots, demonstrating the outcomes of the ERAS group vs the control group after pancreatic surgery, and funnel plots were used to evaluate potential publication bias.RESULTS Twenty case-control studies including 3694 patients, published between January 1995 and August 2017, were selected for the meta-analysis. This study included the ERAS group(n = 1886) and the control group(n = 1808), which adopted the traditional perioperative management. Compared to the control group, the ERAS group had lower delayed gastric emptying rates [odds ratio(OR) = 0.58, 95% confidence interval (CI): 0.48-0.72, P < 0.00001], lower postoperative complication rates(OR = 0.57, 95%CI: 0.45-0.72, P < 0.00001), particularly for the mild postoperative complications(Clavien-Dindo Ⅰ-Ⅱ)(OR = 0.71, 95%CI: 0.58-0.88, P = 0.002), lower abdominal infection rates(OR = 0.70, 95%CI: 0.54-0.90, P = 0.006), and shorter postoperative length of hospital stay(PLOS)(WMD =-4.45, 95%CI:-5.99 to-2.91, P < 0.00001). However, there were no significant differences in complications, such as, postoperative pancreatic fistulas, moderate to severe complications(Clavien-Dindo Ⅲ-Ⅴ), mortality, readmission and unintended reoperation, in both groups.CONCLUSION The perioperative implementation of ERAS programs in pancreatic surgery is safe and effective, can decrease postoperative complication rates, and can promote recovery for patients. | Hai-Bin Ji Wen-Tao Zhu Qiang Wei Xiao-Xiao Wang Hai-Bin Wang Qiang-Pu Chen | 2018 | World Journal of Gastroenterology2018，24，15： | 16 |
| 17 | Liver metastases:Contrast-enhanced ultrasound compared with computed tomography and magnetic resonance显示文摘The development of ultrasound contrast agents with excellent tolerance and safety profiles has notably improved liver evaluation with ultrasound(US)for several applications,especially for the detection of metastases.In particular,contrast enhanced ultrasonography(CEUS)allows the display of the parenchymal microvasculature,enabling the study and visualization of the enhancement patterns of liver lesions in real time and in a continuous manner in all vascular phases,which is similar to contrast-enhanced computed tomography(CT)and contrast-enhanced magnetic resonance imaging.Clinical studies have reported that the use of a contrast agent enables the visualization of more metastases with significantly improved sensitivity and specificity compared to baseline-US.Furthermore,studies have shown that CEUS yields sensitivities comparable to CT.In this review,we describe the state of the art of CEUS for detecting colorectal liver metastases,the imaging features,the literature reports of metastases in CEUS as well as its technique,its clinical role and its potential applications.Additionally,the updated international consensus panel guidelines are reported in this review with the inherent limitations of this technique and best practice experiences. | Vito Cantisani Hektor Grazhdani Cristina Fioravanti Maria Rosignuolo Fabrizio Calliada Daniela Messineo Maria Giulia Bernieri Adriano Redler Carlo Catalano Ferdinando D’Ambrosio | 2014 | World Journal of Gastroenterology2014，20，29： | 16 |
| 18 | Ultrasonography in diagnosing chronic pancreatitis: New aspects显示文摘The course and outcome is poor for most patients with pancreatic diseases.Advances in pancreatic imaging are important in the detection of pancreatic diseases at early stages.Ultrasonography as a diagnostic tool has made,virtually speaking a technical revolution in medical imaging in the new millennium.It has not only become the preferred method for first line imaging,but also,increasingly to clarify the interpretation of other imaging modalities to obtain efficient clinical decision.We review ultrasonography modalities,focusing on advanced pancreatic imaging and its potential to substantially improve diagnosis of pancreatic diseases at earlier stages.In the first section,we describe scanning techniques and examination protocols.Their consequences for image quality and the ability to obtain complete and detailed visualization of the pancreas are discussed.In the second section we outline ultrasonographic characteristics of pancreatic diseases with emphasis on chronic pancreatitis.Finally,new developments in ultrasonography of the pancreas such as contrast enhanced ultrasound and elastography are enlightened. | Georg Dimcevski Friedemann G Erchinger Roald Havre Odd Helge Gilja | 2013 | World Journal of Gastroenterology2013，19，42： | 12 |

| 20 | Contrast enhanced ultrasound of renal masses显示文摘Contrast enhanced ultrasound(CEUS) has gained clinical importance over the last years for the characterization of hepatic masses.Its role in extrahepatic indications has been investigated repeatedly but has been less comprehensively studied.Currently more than 50% of renal masses are incidentally diagnosed,mostly by B-mode ultrasound.The method of choice for characterization of renal lesions is contrast enhanced computed tomography(CECT).In the case of cystic lesions CECT refers to the Bosniak classification for cystic lesions to assess the risk of malignant behavior.The majority of masses are renal cell carcinoma,but the exact proportion is controversial.Disadvantages of CECT are a significant risk for patients with impaired renal function,allergic reactions and hyperthyroidism due to iodinated contrast agents.Several studies concerning CEUS for the characterization of both solid and cystic renal lesions have been published,but prospective multicenter studies are missing,the presented data being mainly descriptive.The aim of the this manuscript is to review the current literature for CEUS in renal masses,to summarize the available data and focus on possible concepts for studies in the future. | Andre Ignee Bad Mergentheim Gudrun Schuessler Christoph Frank Dietrich | 2010 | World Journal of Radiology2010，2，1： | 11 |
