| 1 | Endoscopic ultrasound-guided biliary drainage with placement of a fully covered metal stent for malignant biliary obstruction显示文摘AIM:To determine the utility of endoscopic ultrasoundguided biliary drainage(EUS-BD)with a fully covered self-expandable metal stent for managing malignant biliary stricture. METHODS:We collected data from 13 patients who presented with malignant biliary obstruction and underwent EUS-BD with a nitinol fully covered selfexpandable metal stent when endoscopic retrograde cholangiopancreatography(ERCP)fails.EUS-guided choledochoduodenostomy(EUS-CD)and EUS-guided hepaticogastrostomy(EUS-HG)was performed in 9 patients and 4 patients,respectively. RESULTS:The technical and functional success rate was 92.3%(12/13)and 91.7%(11/12),respectively. Using an intrahepatic approach(EUS-HG,n=4),there was mild peritonitis(n=1)and migration of the metal stent to the stomach(n=1).With an extrahepatic approach(EUS-CD,n=10),there was pneumoperitoneum(n=2),migration(n=2),and mild peritonitis (n=1).All patients were managed conservatively with antibiotics.During follow-up(range,1-12 mo),there was re-intervention(4/13 cases,30.7%)necessitated by stent migration(n=2)and stent occlusion(n=2). CONCLUSION:EUS-BD with a nitinol fully covered self-expandable metal stent may be a feasible and effective treatment option in patients with malignant biliary obstruction when ERCP fails. | Tae Hyeon Kim Seong Hun Kim Hyo Jeong Oh Young Woo Sohn Seung Ok Lee | 2012 | World Journal of Gastroenterology2012，18，20： | 16 |
| 2 | Gastric cancer patients at high-risk of having synchronous cancer显示文摘瞄准:识别病人与一在胃的癌症病人之中有同步癌症高风险。方法:我们回顾地在国家癌症中心分析了未来的胃的癌症数据库,从 2000 年 12 月的朝鲜到 2004 年 12 月。有没有同步癌症的病人的同步癌症和那些的病人的 clinicopathological 特征被比较。Multivariate 分析被执行在胃的癌症病人为同步癌症的存在识别风险因素。结果:在数据库登记的 3291 个胃的癌症病人(3.4%) 中的 111 个有同步癌症。在这 111 个病人之中, 109 有单个同步癌症, 2 个病人有二同步癌症。同步癌症的最普通的形式是颜色表面的癌症(42 个病人, 37.2%) 由肺癌症列在后面(21 个病人, 18.6%) 。Multivariate 分析表明有区分的早胃的癌症的老病人有同步癌症的更高的可能性。结论:在胃的癌症病人的同步癌症不是很少发生的。医生应该试着在胃的癌症病人发现同步癌症,在特别与区分的早胃的癌症老。 | Jun Ho Lee Ja Seong Bae Keun Won Ryu Jong Seok Lee Sook Ryun Park Chan Gyoo Kim Myoung Cheorl Kook Il Ju Choi Young Woo Kim Jae-Gahb Park Jae-Moon Bae | 2006 | World Journal of Gastroenterology2006，12，16： | 15 |
| 3 | Long-term follow up of endoscopic resection for type 3 gastric NET显示文摘AIM:To clarify the short and long-term results and to prove the usefulness of endoscopic resection in type 3gastric neuroendocrine tumors(NETs).METHODS:Of the 119 type 3 gastric NETs diagnosed from January 1996 to September 2011,50 patients treated with endoscopic resection were enrolled in this study.For endoscopic resection,endoscopic mucosal resection(EMR)or endoscopic submucosal dissection(ESD)was used.Therapeutic efficacy,complications,and follow-up results were evaluated retrospectively.RESULTS:EMR was performed in 41 cases and ESD in 9 cases.Pathologically complete resection was performed in 40 cases(80.0%)and incomplete resection specimens were observed in 10 cases(7 vs 3 patients in the EMR vs ESD group,P=0.249).Upon analysis of the incomplete resection group,lateral or vertical margin invasion was found in six cases(14.6%)in the EMR group and in one case in the ESD group(11.1%).Lymphovascular invasions were observed in two cases(22.2%)in the ESD group and in one case(2.4%)in the EMR group(P=0.080).During the follow-up period(43.73;13-60 mo),there was no evidence of tumor recurrence in either the pathologically complete resection group or the incomplete resection group.No recurrence was reported during follow-up.In addition,no mortality was reported in either the complete resection group or the incomplete resection group for the duration of the follow-up period.CONCLUSION:Less than 2 cm sized confined submucosal layer type 3 gastric NET with no evidence of lymphovascular invasion,endoscopic treatment could be considered at initial treatment. | Yong Hwan Kwon Seong Woo Jeon Gwang Ha Kim Jin Il Kim Il-Kwun Chung Sam Ryong Jee Heung Up Kim Geom Seog Seo Gwang Ho Baik Kee Don Choi Jeong Seop Moon | 2013 | World Journal of Gastroenterology2013，19，46： | 14 |
| 4 | Hepatectomy vs radiofrequency ablation for colorectal liver metastasis:A propensity score analysis显示文摘AIM:To compare outcomes from radiofrequency ablation(RFA) and hepatectomy for treatment of colorectal liver metastasis(CRLM).METHODS:From January 2000 to December 2009,408 patients underwent curative intent treatment for CRLM.We excluded patients using the criteria:size of CRLM > 3 cm,number of CRLM ≥ 5,percutaneous RFA,follow-up period < 12 mo,double primary cancer,or treatment with both RFA and hepatectomy.We matched 51 patients who underwent RFA with 102 patients who underwent hepatectomy by propensity scores.RESULTS:The median follow-up period was 45 mo(range,12 mo to 158 mo).Hepatic recurrence was more frequent in the RFA than the hepatectomy group(P = 0.021) although extrahepatic recurrence curves were similar(P = 0.716).Survival curves of hepatectomy group were better than that of RFA for multiple,large(> 2 cm) CRLM(P = 0.034).However,survival curves were similar for single or small(≤ 2 cm) CRLM(P = 0.714,P = 0.740).CONCLUSION:Hepatectomy is better than RFA for the treatment of CRLM.However,RFA might be suitable for selected patients with single,small(≤ 2 cm) CRLM. | Huisong Lee Jin Seok Heo Yong Beom Cho Seong Hyeon Yun Hee Cheol Kim Woo Yong Lee Seong Ho Choi Dong Wook Choi | 2015 | World Journal of Gastroenterology2015，21，11： | 14 |
| 5 | Preoperative colonoscopy through the colonic stent in patients with colorectal cancer obstruction显示文摘AIM:To evaluate the feasibility of a preoperative colonoscopy through a self-expendable metallic stent(SEMS)and to identify the factors that affect complete colonoscopy.METHODS:A total of 48 patients who had SEMS placement because of acute malignant colonic obstruction underwent preoperative colonoscopy.After effective SEMS placement,patients who showed complete resolution of radiological findings and clinical signs of acute colon obstruction underwent a standard bowel preparation.Preoperative colonoscopy was then performed using a standard colonoscope.If the passage of colonoscope was not feasible gastroscope was used.After colonoscopy,cecal intubation time,grade of bowel preparation,tumor location,stent location,presence of synchronous polyps or cancer,damage to colonoscopy and bleeding,and stent migration after colonoscopy were recorded.RESULTS:Complete evaluation with colonoscope was possible in 30 patients(62.5%).In this group,adenoma was detected in 13 patients(43.3%).The factors that affected complete colonoscopy were also analyzed:Tumor location at an angle;stent placement at an angle;and stent expansion diameter,which affected complete colonoscopy significantly.However in multivariate analysis,stent expansion diameter was the only significant factor that affected complete colonoscopy.Complete evaluation using additional gastroscope was feasible in 42 patients(87.5%).CONCLUSION:Preoperative colonoscopy through the colonic stent using only conventional colonoscope was unfavorable.The narrow expansion diameter of the stent may predict unfavorable outcome.In such a case,using small caliber scope should be considered and may expect successful outcome. | Jin Su Kim Kang Moon Lee Sang Woo Kim Eun Jung Kim Chul Hyun Lim Seong Taek Oh Myung Gyu Choi Kyu Yong Choi | 2014 | World Journal of Gastroenterology2014，20，30： | 11 |
| 6 | Multiplanar reformations and minimum intensity projections using multi-detector row CT for assessing anomalies and disorders of the pancreaticobiliary tree显示文摘CT scan is regarded as the imaging modality of choice in patients with pancreaticobiliary ductal abnormalities. However, the axial orientation of the CT images provides only limited anatomical view of pancreaticobiliary ductal abnormalities. The technological advances of multi-de-tector row CT and three-dimensional image processing in workstations allows rapid image acquisition and a short postprocessing time. In particular, multiplanar reforma-tions (MPR) and minimum intensity projections (MinIP) offer rapid and accurate images of the anatomy and ab-normalities of the pancreaticobiliary tree. Moreover, MPR and MinIP help determine the relationship between the pancreaticobiliary ductal anatomy and the surrounding structures. This pictorial review illustrates the wide spec-trum of images obtained by the MPR and MinIP of the anomalies and disorders of the pancreaticobiliary tree. | Hyun Cheol Kim Dal Mo Yang Wook Jin Chang Woo Ryu Jung Kyu Ryu Sung Il Park Seong Jin Park Hyeong Cheol Shin Il Young Kim | 2007 | World Journal of Gastroenterology2007，13，31： | 10 |
| 7 | Effect of focal laser photocoagulation in eyes with mild to moderate non-proliferative diabetic retinopathy显示文摘AIM:To report the effect of focal laser photocoagulation on both the severity of hard exudates(HEs) and the rate of disease progression in eyes with mild to moderate non-proliferative diabetic retinopathy(NPDR).METHODS: We retrospectively reviewed the medical records of 33 patients(60 eyes) who had been diagnosed with mild to moderate NPDR between January 2006 and December 2012.The patients were divided into 2 groups:Group A(38 eyes in 20 patients treated using focal laser photocoagulation) and Group B(treated without laser photocoagulation).We also reviewed the best corrected visual acuity measurements,and the fundus photographs taken at both baseline and follow-up visits. RESULTS: In Group A,HE severity grade had decreased significantly from baseline to the final visit(P <0.05),but this was not the case in Group B(P =0.662).The cumulative probabilities of retinopathy progression at 5y were 26% in Group A and 30% in Group B.KaplanMeier survival curves showed no significant difference between the groups with regard to retinopathy progression(P =0.805).CONCLUSION: Focal laser photocoagulation reduced the levels of HEs in eyes with mild to moderate NPDR.However,the treatment was not able to decelerate the progression of DR. | Seong Hun Jeong Jung Il Han Sung Won Cho Dong Won Lee Chul Gu Kim Tae Gon Lee Jong Woo Kim | 2016 | International Journal of Ophthalmology(English edition)2016，9，10： | 10 |
| 8 | Removal of primary iron rich phase from aluminum-silicon melt by centrifugal separation显示文摘Recycling is a major consideration in continued aluminum use due to the enormous demand for high quality products. Some impurity elements gradually accumulate through the repetitive reuse of aluminum alloy scrap. Of them, the iron content should be suppressed under the allowed limit. In the present research, a novel separation method was introduced to remove primary iron-rich intermetallic compounds by centrifugation during solidification of Al-Si-Fe alloys. This method does not use the density difference between two phases as in other centrifugal methods, but uses the order of solidification in Al-Si-Fe alloys, because iron promotes the formation of intermetallic compounds with other alloying elements as a primary phase. Two Al-Si-Fe alloys which have different iron contents were chosen as the starting materials. The iron-rich phase could be efficiently removed by centrifuging under a centrifugal force of 40 g. Coarse intermetallic compounds were found in the sample inside the crucible, while rather fine intermetallic compounds were found in the sample outside the crucible. Primary intermetallic compounds were linked to each other via aluminum-rich matrix, and formed like a network. The highest iron removal fraction is 67% and the lowest one is 7% for Al-12Si-1.7Fe alloy. And they are 82% and 18% for Al-12Si-3.4Fe alloy, respectively. | Seong Woo Kim Un Ho Im Hyeong Cheol Cha Se Hyeong Kim Ji Eun Jang Ki Young Kim | 2013 | China Foundry2013，10，2： | 8 |
| 9 | Optimal treatment strategy for Helicobacter pylori:Era of antibiotic resistance显示文摘Standard triple therapy,consisting of a proton pump inhibitor,plus amoxicillin and clarithromycin,has been the most commonly used first-line treatment regimen for Helicobacter pylori(H.pylori)eradication for many years worldwide.However,as a result of increased resistance to antibiotics,H.pylori eradication rates with use of standard triple therapy have been declining and recently reached<80%in many countries.Several new strategies to enhance the eradication rate of H.pylori have been studied.Currently,among the alternative first-line eradication regimens,concomitant and hybrid regimens have shown excellent results and could be the optimal treatment option.Although clinical usefulness of rescue therapy for patients in whom eradication of H.pylori with non-bismuth quadruple regimen has failed is unclear,levofloxacin-based quadruple therapy has shown promise as a rescue treatment.The choice of third-line therapy depends on factors such as the local pattern of antibiotic resistance,drug availability,and previous treatment.We hope that a simple method for detection of antibiotic susceptibility using polymerase chain reaction would be a possible alternative to administration of'tailored treatment'in the era of increasing prevalence of antimicrobial resistance. | Jun Heo Seong Woo Jeon | 2014 | World Journal of Gastroenterology2014，20，19： | 8 |
| 10 | Gastric dysplasia may be an independent risk factor of an advanced colorectal neoplasm显示文摘AIM: To evaluate the relationship between gastric dysplasia and Helicobacter pylori (H pylori) and the occurrence of colorectal adenoma, and to defi ne the necessity for colonoscopy in patients with gastric dysplasia or H pylori infection.METHODS: From May 2005 to February 2008, 133 patients with established gastric dysplasia by gastroduo-denoscopy (EGD) were additionally investigated by colonoscopy. The authors compared results with those of 213 subjects who underwent both EGD and colonoscopy during the same period at the author’s Health Promotion Center as a control group. H pylori infection was evaluated in both the gastric dysplasia and control groups.RESULTS: The mean age of all 346 study subjects was 54.1 ± 10.5 years, and there were 258 (73%) men and 87 (27%) women. No signif icant difference was found between the H pylori positive and negative subjects in terms of the prevalence of colorectal adenoma and advanced colorectal adenoma (P = 0.261). Patients with gastric dysplasia showed no elevated risk of colorectal adenoma (OR = 0.910, 95% CI: 0.587-1.411, P = 0.738), but had a signif icantly higher risk of having advanced colorectal adenoma (OR = 3.382, 95% CI: 1.700-6.342, P = 0.000).CONCLUSION: The study emphasizes the need for colon surveillance in patients with gastric dysplasia, regardless of H pylori infection. | Rack Cheon Bae Seong Woo Jeon Han Jin Cho Min Kyu Jung Young Oh Kweon Sung Kook Kim | 2009 | World Journal of Gastroenterology2009，15，45： | 8 |
| 11 | Super-resolution localization photoacoustic microscopy using intrinsic red blood cells as contrast absorbers显示文摘Photoacoustic microscopy(PAM)has become a premier microscopy tool that can provide the anatomical,functional,and molecular information of animals and humans in vivo.However,conventional PAM systems suffer from limited temporal and/or spatial resolution.Here,we present a fast PAM system and an agent-free localization method based on a stable and commercial galvanometer scanner with a custom-made scanning mirror(L-PAM-GS).This novel hardware implementation enhances the temporal resolution significantly while maintaining a high signal-to-noise ratio(SNR).These improvements allow us to photoacoustically and noninvasively observe the microvasculatures of small animals and humans in vivo.Furthermore,the functional hemodynamics,namely,the blood flow rate in the microvasculature,is successfully monitored and quantified in vivo.More importantly,thanks to the high SNR and fast B-mode rate(500 Hz),by localizing photoacoustic signals from captured red blood cells without any contrast agent,unresolved microvessels are clearly distinguished,and the spatial resolution is improved by a factor of 2.5 in vivo.LPAM-GS has great potential in various fields,such as neurology,oncology,and pathology. | Jongbeom Kim Jin Young Kim Seungwan Jeon Jin Woo BAIK Seong Hee Cho Chulhong Kim | 2019 | Light(Science & Applications)2019，8，1： | 6 |
| 12 | Predicting tumor response after preoperative chemoradiation using clinical parameters in rectal cancer显示文摘AIM: To evaluate the clinical parameters and identify a better method of predicting pathological complete response (pCR). METHODS: We enrolled 249 patients from a database of 544 consecutive rectal cancer patients who underwent surgical resection after preoperative chemoradiation therapy (PCRT). A retrospective review of morphological characteristics was then performed to collect data regarding rectal examination findings. A scoring model to predict pCR was then created. To validate the ability of the scoring model to predict complete regression.RESULTS: Seventy patients (12.9%) achieved a pCR. A multivariate analysis found that pre-CRT movability (P = 0.024), post-CRT size (P = 0.018), post-CRT morphology (P = 0.023), and gross change (P = 0.009) were independent predictors of pCR. The accuracy of the scoring model was 76.8% for predicting pCR with the threshold set at 4.5. In the validation set, the accuracy was 86.7%. CONCLUSION: Gross changes and morphological findings are important predictors of pathological response. Accordingly, PCRT response is best predicted by a combination of clinical, laboratory and metabolic information. | Chan Ho Park Hee Cheol Kim Yong Beom Cho Seong Hyeon Yun Woo Yong Lee Young Suk Park Doo Ho Choi Ho-Kyung Chun | 2011 | World Journal of Gastroenterology2011，17，48： | 6 |
| 13 | Potential risk factors for nonalcoholic steatohepatitis related to pancreatic secretions following pancreaticoduodenectomy显示文摘AIM: To identify risk factors for nonalcoholic steatohepatitis following pancreaticoduodenectomy, with a focus on factors related to pancreatic secretions. METHODS: The medical records of 228 patients who had a pancreaticoduodenectomy over a 16-mo period were reviewed retrospectively. The 193 patients who did not have fatty liver disease preoperatively were included in the final analysis. Hepatic steatosis was diagnosed using the differences between splenic and hepatic attenuation and liver-to-spleen attenuation as measured by non-enhanced computed tomography. RESULTS: Fifteen patients (7.8%) who showed postoperative hepatic fatty changes were assigned to Group A, and the remaining patients were assigned to Group B. Patient demographics, preoperative laboratory findings (including levels of C-peptide, glucagon, insulin and glucose tolerance test results), operation types, and final pathological findings did not differ significantly between the two groups; however, the frequency of pancreatic fistula (P = 0.020) and the method of pancreatic duct stenting (P = 0.005) showed significant differences between the groups. A multivari- ate analysis identified pancreatic fistula (HR = 3.332, P = 0.037) and external pancreatic duct stenting (HR = 4.530, P = 0.017) as independent risk factors for the development of postoperative steatohepatitis. CONCLUSION: Pancreatic fistula and external pancreatic duct stenting were identified as independent risk factors for the development of steatohepatitis following pancreaticoduodenectomy. | Sun Choon Song Seong Ho Choi Dong Wook Choi Jin Seok Heo Woo Seok Kim Min Jung Kim | 2011 | World Journal of Gastroenterology2011，17，32： | 5 |
| 14 | Endoscopic resection of co-existing severe dysplasia and a small esophageal leiomyoma显示文摘Leiomyoma is the most common benign mesenchymal tumor of the esophagus.A small leiomyoma covered with endoscopically normal mucosa has a characteristic endoscopic ultrasonographic appearance,slow growth rate,and negligible risk of malignant transformation;therefore the histology does not need to be proven.Synchronous tumors such as an epithelial tumor and small subepithelial tumor in the upper gastrointestinal tract are uncommon.We describe a case with a coexisting small leiomyoma and severe dysplasia in the esophagus which were completely resected by endoscopic mucosal resection. | Sun Young Ahn Seong Woo Jeon | 2013 | World Journal of Gastroenterology2013，19，1： | 5 |
| 15 | Clinical outcome of Fitz-Hugh-Curtis syndrome mimicking acute biliary disease显示文摘AIM: To analyze the clinical characteristics of patients diagnosed with Fitz-Hugh-Curtis syndrome.METHODS: The clinical courses of patients that visited St. Mary's Hospital with abdominal pain from January 2005 to December 2006 and were diagnosed with Fitz-Hugh-Curtis syndrome were examined.RESULTS: Fitz-Hugh-Curtis syndrome was identified in 22 female patients of childbearing age; their mean age was 31.0 ± 8.1 years. Fourteen of these cases presented with pain in the upper right abdomen alone or together with pain in the lower abdomen, and six patients presented with pain only in the lower abdomen. The first impression at the time of visit was acute cholecystitis or cholangitis in 10 patients and acute appendicitis or pelvic inflammatory disease in eight patients. Twenty-one patients were diagnosed by abdominal computer tomograghy (CT), and the results of abdominal sonography were normal for 10 of these patients. Chlamydia trichomatis was isolated from 18 patients. Two patients underwent laparoscopic adhesiotomy and 20 patients were completely cured by antibiotic treatment.CONCLUSION: For women of childbearing age with acute pain in the upper right abdomen alone or together with pain in the lower abdomen, Fitz-Hugh-Curtis syndrome should be considered during differential diagnosis. Moreover, in cases suspected to be Fitz-Hugh-Curtis syndrome, abdominal CT, rather than abdominal sonography, assists in the diagnosis. | Seong Yong Woo Jin Il Kim Dae Young Cheung Se Hyun Cho Soo-Heon Park Joon-Yeol Han Jae Kwang Kim | 2008 | World Journal of Gastroenterology2008，14，45： | 5 |
| 16 | Significant risk and associated factors of active tuberculosis infection in Korean patients with inflammatory bowel disease using anti-TNF agents显示文摘AIM:To evaluate the incidence and risk factors of Korean tuberculosis(TB) infection in patients with inflammatory bowel disease(IBD) undergoing anti-TNF treatment.METHODS:The data of IBD patients treated with anti-TNFs in 13 tertiary referral hospitals located in the southeastern region of Korea were collected retrospectively.They failed to show response or were intolerant to conventional treatments,including steroids or immunomodulators.Screening measures for latent TB infection(LTBI)and the incidence and risk factors ofactive TB infection after treatment with anti-TNFs were identified.RESULTS:Overall,376 IBD patients treated with antiTNF agents were recruited(male 255,mean age of anti-TNF therapy 32.5±13.0 years);277 had Crohn’s disease,99 had ulcerative colitis,294 used infliximab,and 82 used adalimumab.Before anti-TNF treatment,screening tests for LTBI including an interferon gamma release assay or a tuberculin skin test were performed in 82.2%of patients.Thirty patients(8%)had LTBI.Sixteen cases of active TB infection including one TB-related mortality occurred during 801 personyears(PY)follow-up(1997.4 cases per 100000 PY)after anti-TNF treatment.LTBI(OR=5.76,95%CI:1.57-21.20,P=0.008)and WBC count<5000 mm3(OR=4.5,95%CI:1.51-13.44,P=0.007)during follow-up were identified as independently associated risk factors.CONCLUSION:Anti-TNFs significantly increase the risk of TB infection in Korean patients with IBD.The considerable burden of TB and marked immunosuppression might be attributed to this risk. | Eun Soo Kim Geun Am Song Kwang Bum Cho Kyung Sik Park Kyeong Ok Kim Byung Ik Jang Eun Young Kim Seong Woo Jeon Hyun Seok Lee Chang Heon Yang Yong Kook Lee Dong Wook Lee Sung Kook Kim Tae Oh Kim Jonghun Lee Hyung Wook Kim Sam Ryong Jee Seun Ja Park Hyun Jin Kim | 2015 | World Journal of Gastroenterology2015，21，11： | 5 |
| 17 | Microbiology and risk factors for gram-positive Cocci bacteremia in biliary infections显示文摘Background:The rapid antibiotics treatment targeted to a specific pathogen can improve clinical outcomes of septicemia.We aimed to evaluate the clinical characteristics and outcomes of biliary septicemia caused by cholangitis or cholecystitis according to causative organisms.Methods:We performed a retrospective cohort study in 151 patients diagnosed with cholangitis or cholecystitis with bacterial septicemia from January 2013 to December 2015.All patients showed clinical evidence of biliary tract infection and had blood isolates that demonstrated septicemia.Results:Gram-negative,gram-positive,and both types of bacteria caused 84.1%(127/151),13.2%(20/151),and 2.6%(4/151)episodes of septicemia,respectively.The most common infecting organisms were Escherichia coli among gram-negative bacteria and Enterococcus species(Enterococcus casseliflavus and Enterococcus faecalis)among gram-positive bacteria.There were no differences in mortality,re-admission rate,and need for emergency decompression procedures between the gram-positive and gram-negative septicemia groups.In univariate analysis,previous gastrectomy history was associated with gram-positive bacteremia.Multivariate analysis also showed that previous gastrectomy history was strongly associated with gram-positive septicemia(Odds ratio=5.47,95%CI:1.19–25.23;P=0.029).Conclusions:Previous gastrectomy history was related to biliary septicemia induced by gram-positive organisms.This information would aid the choice of empirical antibiotics. | Ik Hyun Jo Yeon-Ji Kim Woo Chul Chung Jaeyoung Kim Seonhoo Kim Eun Sun Lim Honggeun Ahn Seong Yul Ryu | 2020 | Hepatobiliary & Pancreatic Diseases International2020，19，5： | 4 |

| 19 | Intrauterine midgut volvulus without malrotation:Diagnosis from the 'coffee bean sign'显示文摘Fetal midgut volvulus is quite rare, and most cases are associated with abnormalities of intestinal rotation or fixation. We report a case of midgut volvulus without malrotation, associated with a meconium pellet, during the gestation period. This 2.79 kg, 33-wk infant was born via a spontaneous vaginal delivery caused by preterm labor. Prenatal ultrasound showed dilated bowel loops with the appearance of a 'coffee bean sign'. This patient had an unusual presentation with a distended abdomen showing skin discoloration. An emergency laparotomy revealed a midgut volvulus and a twisted small bowel, caused by complicated meconium ileus. Such nonspecific prenatal radiological signs and a low index of suspicion of a volvulus during gestation might delay appropriate surgical management and result in ischemic necrosis of the bowel. Preterm labor, specific prenatal sonographic findings (for example, the coffee bean sign) and bluish discoloration of the abdominal wall could suggest intrauterine midgut volvulus requiring prompt surgical intervention. | Jun Seok Park Seong Jae Cha Beom Gyu Kim Yong Seok Kim Yoo Shin Choi In Taik Chang Gwang Jun Kim Woo Seok Lee Gi Hyeon Kim | 2008 | World Journal of Gastroenterology2008，14，9： | 4 |
| 20 | Repeat hepatic resection in patients with colorectal liver metastases显示文摘AIM:To investigate the survival outcomes of secondaryhepatectomy for recurrent colorectal liver metastases(CRLM).METHODS:From October 1994 to December 2009,patients with CRLM who underwent surgical treatment with curative intent were investigated.Patients were divided into two groups:patients who underwent primary hepatectomy(Group 1)and those who underwent secondary hepatectomy for recurrent CRLM(Group 2).RESULTS:Survival and prognostic factors were analyzed.A total of 461 patients were included:406patients in Group 1 and 55 patients in Group 2.After a median 39-mo(range,3-195 mo)follow-up,there was a significant difference between Groups 1 and 2in terms of disease-free survival(P=0.029)although there was no significant difference in overall survival(P=0.206).Secondary hepatectomy was less effective in patients with multiple recurrent CRLM than primary hepatectomy for initial CRLM(P=0.008).Multiple CRLM and radiofrequency ablation therapy were poor prognostic factors of secondary hepatectomy in multivariate Cox regression analysis(P=0.006,P=0.004,respectively).CONCLUSION:Secondary hepatectomy for single recurrent CRLM is as effective as primary surgical treatment for single recurrent CRLM.However,secondary hepatectomy for multiple recurrent CRLM is less effective than that for single recurrent CRLM. | Huisong Lee Seong Ho Choi Yong Beom Cho Seong Hyeon Yun Hee Cheol Kim Woo Yong Lee Jin Seok Heo Dong Wook Choi Kyung Uk Jung Ho-Kyung Chun | 2015 | World Journal of Gastroenterology2015，21，7： | 4 |
