| 1 | How good is cola for dissolution of gastric phytobezoars?显示文摘AIM:To evaluate the efficacy of cola treatment for gastric phytobezoars,including diospyrobezoars.METHODS:A total of 17 patients(range:48 to 78 years) with symptomatic gastric phytobezoars treated with cola and adjuvant endoscopic therapy were reviewed.Three liters of cola lavage(10 cases) or drink(7 cases) were initially used,and then endoscopic fragmentation was done for the remnant bezoars by using a lithotripsy basket or a polypectomy snare.The overall success of dissolving a gastric phytobezoars with using three liters of cola and the clinical and endoscopic findings were compared retrospectively between four cases of complete dissolution by using only cola and 13 cases of partial dissolution with cola.RESULTS:After 3 L of cola lavage or drinking,a complete dissolution of bezoars was achieved in four patients(23.5%),while 13 cases(76.5%) were only partially dissolved.Phytobezoars(4 of 6 cases) were observed more frequently than diospyrobezoars(0 of 11) in the group that underwent complete dissolution(P = 0.006).Gender,symptom duration,size of bezoar and method of cola administration were not significantly different between the two groups.Twelve of 13 patients with residual bezoars were completely treated with a combination of cola and endoscopic fragmentation.CONCLUSION:The rate of complete dissolution with three liters of cola was 23.5%,but no case of diospyrobezoar was completely dissolved using this method.However,pretreatment with cola may be helpful and facilitate endoscopic fragmentation of gastric phytobezoars. | Beom Jae Lee Jong-Jae Park Hoon Jai Chun Ji Hoon Kim Jong Eun Yeon Yoon Tae Jeen Jae Seon Kim Kwan Soo Byun Sang Woo Lee Jae Hyun Choi Chang Duck Kim Ho Sang Ryu Young-Tae Bak | 2009 | World Journal of Gastroenterology2009，15，18： | 22 |
| 2 | Anemia after gastrectomy for early gastric cancer:Long-term follow-up observational study显示文摘AIM:To identify the incidence and etiology of anemia after gastrectomy in patients with long-term follow-up after gastrectomy for early gastric cancer.METHODS:The medical records of those patients with early gastric adenocarcinoma who underwent curative gastrectomy between January 2006 and October 2007 were reviewed.Patients with anemia in the preoperative workup,cancer recurrence,undergoing systemic chemotherapy,with other medical conditions that can cause anemia,or treated during follow up with red cell transfusions or supplements for anemia were excluded.Anemia was defined by World Health Organization criteria(Hb < 12 g/dL in women and < 13 g/dL in men).Iron deficiency was defined as serum ferritin < 20 g/dL.Vitamin B12 deficiency was defined as serum vitamin B 12 < 200 pg/mL.Iron deficiency anemia was defined as anemia with concomitant iron deficiency.Anemia from vitamin B 12 deficiency was defined as megaloblastic anemia(mean cell volume > 100 fL) with vitamin B 12 deficiency.The profile of anemia over 48 mo of follow-up was analyzed.RESULTS:One hundred sixty-one patients with gastrectomy for early gastric cancer were analyzed.The incidence of anemia was 24.5% at 3 mo after surgery and increased up to 37.1% at 48 mo after surgery.The incidence of iron deficiency anemia increased during the follow up and became the major cause of anemia at 48 mo after surgery.Anemia of chronic disease and megaloblastic anemia were uncommon.The incidence of anemia in female patients was significantly higher than in male patients at 12(40.0% vs 22.0%,P = 0.033),24(45.0% vs 25.0%,P = 0.023),36(55.0% vs 28.0%,P = 0.004),and 48 mo(52.0% vs 31.0%,P = 0.022) after surgery.Patients with total gastrectomy showed significantly higher incidence of anemia than patients with subtotal gastrectomy at 48 mo after surgery(60.7% vs 31.3%,P = 0.008).The incidence of iron deficiency was significantly higher in female patients than in male patients at 6(35.4% vs 13.3%,P = 0.002),12(45.8% vs 16.8%,P < 0.001),18(52.1% vs 22.3%,P < 0.001),24(60.4% vs 20.9%,P < 0.001),36(62.5% vs 29.2%,P < 0.001),and 48 mo(66.7% vs 34.7%,P = 0.001) after surgery.CONCLUSION:Anemia was frequent after gastrectomy for early gastric cancer,with iron deficiency being the major cause.Evaluation for anemia including iron status should be performed after gastrectomy and appropriate iron replacement should be considered. | Chul-Hyun Lim Sang Woo Kim Won Chul Kim Jin Soo Kim Yu Kyung Cho Jae Myung Park In Seok Lee Myung-Gyu Choi Kyo-Young Song Hae Myung Jeon Cho-Hyun Park | 2012 | World Journal of Gastroenterology2012，18，42： | 18 |
| 3 | Computed tomography and magnetic resonance imaging evaluation of lymph node metastasis in early colorectal cancer显示文摘AIM: To assess the role of computed tomography(CT) and magnetic resonance imaging(MRI) and establish imaging criteria of lymph node metastasis in early colorectal cancer.METHODS: One hundred and sixty patients with early colorectal cancer were evaluated for tumor location, clinical history of polypectomy, depth of tumor invasion, and lymph node metastasis. Two radiologists assessed preoperative CT and/or MRI for the primary tumor site detectability, the presence or absence of regional lymph node, and the size of the largest lymph node. Demographic, imaging, and pathologic findings were compared between the two groups of patients based on pathologic lymph node metastasis and optimal size criterion was obtained.RESULTS: The locations of tumor were ascending, transverse, descending, sigmoid colon, and rectum. One hundred and sixty early colorectal cancers were classified into 3 groups based on the pathological depth of tumor invasion; mucosa, submucosa, and depth unavailable. A total of 20(12.5%) cancers with submucosal invasion showed lymph node metastasis. Lymph nodes were detected on CT or MRI in 53 patients. The detection rate and size of lymph nodes were significantly higher(P = 0.000, P = 0.044, respectively) in patients with pathologic nodal metastasis than in patients without nodal metastasis. Receiver operating curve analysis showed that a cut-off value of 4.1 mm is optimal with a sensitivity of 78.6% and specificity of 75%.CONCLUSION: The short diameter size criterion of≥ 4.1 mm for metastatic lymph nodes was optimal for nodal staging in early colorectal cancer. | Joonsung Choi Soon Nam Oh Dong-Myung Yeo Won Kyung Kang Chan-Kwon Jung Sang Woo Kim Michael Yong Park | 2015 | World Journal of Gastroenterology2015，21，2： | 16 |
| 4 | Effect of itopride, a new prokinetic, in patients with mild GERD: A pilot study显示文摘AIM: Itopride is a newly developed prokinetic agent, which enhances gastric motility through both antidopaminergic and anti-acetylcholinesterasic actions. The importance of esophageal motor dysfunction in the pathogenesis of gastro-esophageal reflux disease (GERD) makes it interesting to examine the effect of itopride on esophageal acid exposure.METHODS: The effect of itopride on esophageal acid reflux variables for 24 h was studied in 26 patients with GERD symptoms, pre-entry total acid exposure time (pH<4) of more than 5% and mild esophagitis (SavaryMiller grades Ⅰ, Ⅱ) proven by endoscopy. Ambulatory 24-h pH-metry and symptom assessment were performed after treatments with 150 or 300 mg itopride thrice a day (t.i.d.) for 30 d in random order, using an open label method.For evaluating the safety of itopride, blood biochemical laboratory test was performed and the serum prolactin level was also examined before and after treatment.RESULTS: Total symptom score was significantly decreased after treatment in 150- or 300-mg group. Itopride 300mg was significantly effective than 150 mg on decreasing the total per cent time with pH<4, total time with pH<4and DeMeester score. No serious adverse effects were observed with administration of itopride in both groups.CONCLUSION: Itopride 100 mg t.i.d, is effective on decreasing pathologic reflux in patient with GERD and therefore it has the potential to be effective in the treatment of this disease. | Yong Sung Kim Tae Hyeon Kim Chang Soo Choi Young Woo Shon Sang Wook Kim Geom Seog Seo Yong Ho Nah Myung Gyu Choi Suck Chei Choi | 2005 | World Journal of Gastroenterology2005，11，27： | 15 |
| 5 | Prevalence of clonorchiasis in patients with gastrointestinal disease: A Korean nationwide multicenter survey显示文摘AIM: To investigate prevalence of Clonorchis sinensis in patients with gastrointestinal symptoms, and the relation of the infection to hepatobiliary diseases in 26 hospitals in Korea.METHODS: Consecutive patients who had been admitted to the Division of Gastroenterology with gastrointestinal symptoms were enrolled from March to April 2005. Of those who had been diagnosed with clonorchiasis, epidemiology and correlation between infection and hepatobiliary diseases were surveyed by questionnaire.RESULTS: Of 3080 patients with gastrointestinal diseases, 396 (12.9%) had clonorchiasis and 1140 patients (37.2%) had a history of eating raw freshwater fish. Of those with a history of raw freshwater fish ingestion, 238 (20.9%) patients had clonorchiasis. Cholangiocarcinoma was more prevalent in C. sinensis-infected patients than non-infected patients [34/396 (8.6%) vs 145/2684 (5.4%), P = 0.015]. Cholangiocarcinoma and clonorchiasis showed statistically significant positive cross-relation (P = 0.008). Choledocholithiasis, cholecystolithiasis, cholangitis, hepatocellular carcinoma, and biliary pancreatitis did not correlate with clonorchiasis.CONCLUSION: Infection rate of clonorchiasis was still high in patients with gastrointestinal diseases in Korea, and has not decreased very much during the last two decades. Cholangiocarcinoma was related to clonorchiasis, which suggested an etiological role for the parasite. | Ho Gak Kim Jimin Han Myung-Hwan Kim Kyu Hyun Cho Im Hee Shin Gwang Ha Kim Jae Seon Kim Jin Bong Kim Tae Nyeun Kim Tae Hyeon Kim Tae Hyo Kim Jae Woo Kim Ji Kon Ryu Young-Soo Moon Jong Ho Moon Sung Jae Park Chan Guk Park Sung-Jo Bang Chang Heon Yang Kyo-Sang Yoo Byung Moo Yoo Kyu Taek Lee Dong Ki Lee Byung Seok Lee Sang Soo Lee Seung Ok Lee Woo Jin Lee Chang Min Cho Young-Eun Joo Gab Jin Cheon Young Woo Choi Jae Bok Chung Yong Bum Yoon | 2009 | World Journal of Gastroenterology2009，15，1： | 15 |

| 7 | Carbon and nitrogen dynamics in a Pinus densiflora forest with low and high stand densities显示文摘Aims Understanding carbon(C)and nitrogen(N)dynamics and their dependence on the stand density of an even-aged,mature forest provides knowledge that is important for forest management.This study investigated the differences in ecosystem total C and N storage and flux between a low-density stand(LD)and a high-density stand(HD)and examined the effects of stand density on aboveground net primary productivity(ANPP),total belowground C allocation(TBCA)and net ecosystem production(NEP)in a naturally regenerated,65-to 75-year-old Pinus densiflora S.et Z.forest.Methods LD(450 trees ha^(−1))and HD(842 trees ha^(−1))were established in an even-aged,mature P.densiflora forest in September 2006.The forest had been naturally regenerated following harvesting,and the stand density was naturally maintained without any artificial management such as thinning.The diameter at breast height(DBH≥5.0cm)of all live stems within the stands was measured yearly from 2007 to 2011.To compare C and N storage and fluxes in LD and HD,C and N pools in aboveground and belowground biomass,the forest floor,coarse woody debris(CWD)and soil;soil CO_(2) efflux(R_(S));autotrophic respiration(R_(A));litter production;and soil N availability were measured.Further,ANPP,TBCA and NEP were estimated from plot-based measurement data.Important Findings Ecosystem C(Mg C ha^(−1))and N(Mg N ha^(−1))storage was,respectively,173.0±7.3(mean±SE)and 4.69±0.30 for LD and 162±11.8 and 4.08±0.18 for HD.There were no significant differences in C and N storage in the ecosystem components,except for soils,between the two stands.In contrast,there were significant differences in aboveground ANPP and TBCA between the two stands(P<0.05).Litterfall,biomass increment and R_(S) were major C flux components with values of,respectively,3.89,3.74 and 9.07 Mg C ha^(−1) year^(−1) in LD and 3.15,2.94 and 7.06 Mg C ha^(−1) year^(−1) in HD.Biometric-based NEP(Mg C ha^(−1) year^(−1))was 4.18 in LD and 5.50 in HD.Although the even-aged,mature P.densiflora forest had similar C and N allocation patterns,it showed different C and N dynamics depending on stand density.The results of the current study will be useful for elucidating the effects of stand density on C and N storage and fluxes,which are important issues in managing natural mature forest ecosystems. | Nam Jin Noh Choonsig Kim Sang Won Bae Woo Kyun Lee Tae Kyung Yoon Hiroyuki Muraoka Yowhan Son | 2013 | Journal of Plant Ecology2013，6，5： | 14 |
| 8 | Short-term interval combined chemoembolization and radiofrequency ablation for hepatocellular carcinoma显示文摘AIM:To investigate hepatic function after combined transcatheter arterial chemoembolization(TACE) and radiofrequency ablation(RFA) with a short-term interval(0-2 d).METHODS:A total of 115 patients with compensated liver cirrhosis underwent RFA combined with TACE at a time-interval of 0-2 d for the treatment of hepatocellular carcinoma(HCC)<5.0 cm.There were 21 patients who received further hepatic directed treatment altering liver function within 12 mo after the combined therapy for HCC-recurrence,and were excluded.The remaining94 patients who survived without HCC-recurrence were included in this retrospective study.RESULTS:At 1 mo after treatment,Child-Pugh scores(CPs)remained unchanged in 89 of 94 patients(94.7%),and transiently increased by one-point in 5 patients(5.3%).However,the score returned to baseline score at 3 mo and was maintained until 6 mo in all patients.The baseline CPs of 8 or more was identified as a factor for transient rise of CPs after the treatment(CPs 8/9 vs5/6/7;21.4%vs 2.5%;P=0.022).At 12 mo followup,CPs was unchanged in 90 patients(95.7%),and increased by one-point in 4 patients(4.3%).The rise of CPs at 12 mo was not statistically associated with the initial transient rise of CPs.There were procedure-related complications in 3 patients(3.2%),but the complications were resolved by medical and interventional treatments without hepatic functional sequelae.CONCLUSION:The combined TACE and RFA with an interval of 0-2 d are safe for the management of HCC<5 cm in cirrhotic patients. | Won Hyeok Choe Young Jun Kim Hee Sun Park Sang Woo Park Jeong Han Kim So Young Kwon | 2014 | World Journal of Gastroenterology2014，20，35： | 13 |
| 9 | Low grade gastric mucosa associated lymphoid tissue lymphoma:Treatment strategies based on 10 year follow-up显示文摘AIM:To deduce strategic guidelines of gastric mucosa associated lymphoid tissue lymphoma (MALTOMA) by evaluating the long-term outcome of patients in respect to various treatment modalities.METHODS:A total of 55 patients with MALTOMA from May 1992 to August 2002 were retrospectively reviewed.RESULTS: Complete remission was obtained in 24 (82.8%) of 29 patients treated with anti Helicobacter pylori(H pylori) regimen only. The duration to reach complete remission was 12 months (85 percentile, 2-33 months).Five patients showed complete remission with radiation therapy (26-86 months).Two of them were Hpyloritreatment failure cases.CONCLUSION: Hpylorieradication is an effective primary treatment option for low grade MALTOMA and radiation therapy could be considered in patients with no evidence of Hpyloninfection or who do not respond to Hpylorieradication therapy 12 months after successful eradication. | Sang Kil Lee Yong Chan Lee Jae Bock Chung Chae Yoon Chon Young Myoung Moon Jin Kyung Kang In-Suh Park Chang Ok Suh Woo Ik Yang | 2004 | World Journal of Gastroenterology2004，10，2： | 12 |

| 11 | 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 |
| 12 | Toothpick impaction with sigmoid colon pseudodiverticulum formation successfully treated with colonoscopy显示文摘Foreign bodies in the colon are encountered with increasing frequency, but only sporadic reports concerning their management have appeared in the literature. While most ingested foreign bodies usually pass through the gastrointestinal tract uneventfully, sharp foreign bodies such as toothpicks infrequently cause intestinal perforation and may even result in death. We report our experience with a patient with a sigmoid colon pseudodiverticulum formation, a complication of accidental ingestion of a toothpick that was diagnosed and successfully managed colonoscopically. | Youn Son Chung Yong Woo Chung Sun You Moon Su Mi Yoon Min-Jeong Kim Kyoung Oh Kim Cheol Hee Park Taeho Hahn Kyo-Sang Yoo Sang Hoon Park Jong Hyeok Kim Choong Kee Park | 2008 | World Journal of Gastroenterology2008，14，6： | 10 |
| 13 | Surgical outcome of pancreatic cancer using radical antegrade modular pancreatosplenectomy procedure显示文摘AIM:To evaluate the surgical outcomes following radical antegrade modular pancreatosplenectomy (RAMPS) for pancreatic cancer. METHODS:Twenty-four patients underwent RAMPS with curative intent between January 2005 and June 2009 at the National Cancer Center, South Korea. Clinicopathologic data, including age, sex, operative findings, pathologic results, adjuvant therapy, postop-erative clinical course and follow-up data were retro-spectively collected and analyzed for this study. RESULTS:Twenty-one patients (87.5%) underwent distal pancreatectomy and 3 patients (12.5%) underwent total pancreatectomy using RAMPS. Nine patients (37.5%) underwent combined vessel resection, including 8 superior mesenteric-portal vein resections and 1 celiac axis resection. Two patients (8.3%) underwent combined resection of other organs, including the colon, stomach or duodenum. Negative tangential margins were achieved in 22 patients (91.7%). The mean tumor diameter for all patients was 4.09 ± 2.15 cm. The 2 patients with positive margins had a mean diameter of 7.25 cm. The mean number of retrieved lymph nodes was 20.92 ± 11.24 and the node positivity rate was 70.8%. The median survival of the 24 patients was 18.23 ± 6.02 mo. Patients with negative margins had a median survival of 21.80 ± 5.30 mo and those with positive margins had a median survival of 6.47 mo (P = 0.021). Nine patients (37.5%) had postoperative complications, but there were no postoperative mortalities. Pancreatic fistula occurred in 4 patients (16.7%):2 patients had a grade A fistula and 2 had a grade B fistula. On univariate analysis, histologic grade, positive tangential margin, pancreatic fistula and adjuvant therapy were significant prognostic factors for survival. CONCLUSION:RAMPS is a feasible procedure for achieving negative tangential margins in patients with carcinoma of the body and tail of the pancreas. | Ye Rim Chang Sung-Sik Han Sang-Jae Park Seung Duk Lee Tae Suk Yoo Young-Kyu Kim Tae Hyun Kim Sang Myung Woo Woo Jin Lee Eun Kyung Hong | 2012 | World Journal of Gastroenterology2012，18，39： | 9 |
| 14 | Evaluation of esophageal function in patients with esophageal motor abnormalities using multichannel intraluminal impedance esophageal manometry显示文摘AIM: To evaluate the functional aspect of esophageal motility in healthy subjects and in patients who were referred for esophageal function testing using multichannel intraluminal impedance-esophageal manometry (MII-EM), and to assess the clinical utility of MII-EM. METHODS: From September 2003 to January 2004, we performed the MII-EM on healthy volunteers and all the patients who were referred for esophageal function testing. Each patient received 10 liquid and 10 viscous swallows. We analyzed the results, the impedance and the manometric findings. Some of the subjects had additional ambulatory 24-h pH study performed to diagnose gastroesophageal reflux disease (GERD). RESULTS: Among 89 studied subjects, the MII-EM findings showed normal esophageal motility in 50 (56.17%), ineffective esophageal motility (IEM) in 17 (19.10%), nutcracker esophagus in 7 (7.86%), achalasia in 4 (4.49%), and scleroderma esophagus in 11 (12.35%) cases. The completeness and the speed of bolus transit were in the order of nutcracker esophagus, normal manometry and IEM. Some of the swallows showing normal manometry and IEM had incomplete transit. In the achalasia and scleroderma esophagus, almost all the swallows had incomplete transit. The body amplitudes were higher for the swallows with complete transit than for the swallows with incomplete transit. There was not a significant difference in the manometric and impedance findings between the subjects with and without GERD. CONCLUSION: MII-EM is a useful tool in assessing theesophageal function in the patients having esophageal motility abnormality. The primary factors influencing the bolus transit are the amplitude of the esophageal body and normal peristalsis. | Yu Kyung Cho Myung-Gyu Choi Jae Myung Park Jung Hwan Oh Chang Nyol Paik Joon Wook Lee In Seok Lee Sang Woo Kim In-Sik Chung | 2006 | World Journal of Gastroenterology2006，12，39： | 8 |

| 16 | Exophytic inflammatory myofibroblastic tumor of the stomach in an adult woman:A rare cause of hemoperitoneum显示文摘Inflammatory myofibroblastic tumor (IMT) of the stomach in adults is extremely rare, with unpredictable prognosis. We present a 55-year-old woman with a gastric IMT. She experienced sudden abdominal pain 4 d previously. Physical examination showed mild abdominal tenderness in the hypogastrium, but no palpable abnormal abdominal mass. Abdominal CT showed a mass of approximately 8 cm in the gastrocolic ligament. On laparoscopic exploration, unexpected hemoperitoneum of approximately 1.5 L of blood was found, and an exophytic gastric mass of approximately 10 cm, appeared from the anterior wall of the gastric body along the greater curvature. Laparoscopy further showed that non-clotting blood in the abdominal cavity seemed to be from the gastric tumor. After conversion to open surgery for more precise evaluation of the cause of hemoperitoneum and the large friable tumor, gastric wedge resection, including the tumor, was conducted. The final diagnosis was consistent with IMT that originated from the gastric wall. | Seong-Heum Park Jong-Han Kim Byung Wook Min Tae Jin Song Gil Soo Son Seung Joo Kim Sang Woo Lee Hwan-Hoon Chung Ju Han Lee Jun Won Um | 2008 | World Journal of Gastroenterology2008，14，1： | 8 |
| 17 | Risk factors of organ failure in cholangitis with bacteriobilia显示文摘AIM: To identify the risk factors for organ failure(OF) in cholangitis with bacteriobilia.METHODS: This study included 182 patients with acute cholangitis who underwent percutaneous transhepatic biliary drainage between January 2005 and April 2013. We conducted a retrospective analysis of comprehensive clinical and laboratory data.RESULTS: There were 24 cases(13.2%) of OF and five deaths(2.7%). Bile culture was positive for microbial growth in 130 out of 138(94.2%) patients. In multivariate analysis of 130 patients with positivebile cultures, significant predictive factors for OF were the presence of extended-spectrum beta-lactamase(ESBL) organisms in blood cultures, pre-existing renal dysfunction, and choledocholithiasis as an etiology, with odds ratios of 15.376, 6.319, and 3.573, respectively. We developed a scoring system with a regression coefficient of each significant variable. The OF score was calculated using the following equation:(2.7 × ESBL organisms in blood cultures) +(1.8 × pre-existing renal dysfunction) +(1.3 × choledocholithiasis). This scoring system for predicting OF was highly specific(99.1%) and had a positive predictive value of 86.2%.CONCLUSION: ESBL organisms in blood cultures, preexisting renal dysfunction, and choledocholithiasis are risk factors for OF in cholangitis with bacteriobilia. The OF scoring system may aid clinicians to identify a poor prognosis group. | Jae Min Lee Sang Hyub Lee Kwang Hyun Chung Jin Myung Park Ban Seok Lee Woo Hyun Paik Joo Kyung Park Ji Kon Ryu Yong-Tae Kim | 2015 | World Journal of Gastroenterology2015，21，24： | 8 |
| 18 | Endoscopic management of occluded metal biliary stents:Metal versus 10F plastic stents显示文摘AIM:To compare the efficacy of self-expandable metal stents(SEMSs) with 10F plastic stents(PSs) in the endoscopic management of occluded SEMSs.METHODS:We retrospectively reviewed the medical records of 56 patients who underwent SEMS insertion for palliation of unresectable malignant biliary obstruction between 2000 and 2007 and subsequent endoscopic retrograde biliary drainage(ERBD) with SEMS or PS for initial SEMS occlusion between 2000 and 2008.RESULTS:Subsequent ERBD with SEMS was performed in 29 patients and with PS in 27.The median time to stent occlusion after subsequent ERBD was 186 d in the SEMS group and 101 d in the PS group(P= 0.118).Overall median stent patency was 79 d for the SEMS group and 66 d for the PS group(P = 0.379).The mean number of additional biliary drainage procedures after subsequent ERBD in patients that died(n = 50) during the study period was 2.54 ± 4.12 for the SEMS group and 1.85 ± 1.95 for the PS group(P = 0.457).The mean total cost of additional biliary drainage procedures after the occlusion of subsequent SEMS or PS was $410.04 ± 692.60 for the SEMS group and $630.16 ± 671.63 for the PS group(P = 0.260).Tumor ingrowth as the cause of initial SEMS occlusion was the only factor associated with a shorter time to subsequent stent occlusion(101 d for patients with tumor ingrowth vs 268 d for patients without tumor ingrowth,P = 0.008).CONCLUSION:Subsequent ERBD with PSs offered similar patency and number of additional biliary drainage procedures compared to SEMSs in the management of occluded SEMS. | Won Jae Yoon Ji Kon Ryu Jung Won Lee Dong-Won Ahn Yong-Tae Kim Yong Bum Yoon Sang Myung Woo Woo Jin Lee | 2010 | World Journal of Gastroenterology2010，16，42： | 7 |
| 19 | Endoscopic and clinicopathologic characteristics of early gastric cancer with high microsatellite instability显示文摘AIM:To investigate endoscopic and clinicopathologic characteristics of early gastric cancer (EGC) according to microsatellite instability phenotype.METHODS:Data were retrospectively collected from a single tertiary referral center.Of 981 EGC patients surgically treated between December 2003 and October 2007,73 consecutive EGC patients with two or more microsatellite instability (MSI) mutation [high MSI (MSI-H)] and 146 consecutive EGC patients with one or no MSI mutation (non-MSI-H) were selected.The endoscopic and clinicopathologic features were compared between the MSI-H and non-MSI-H EGC groups.RESULTS:In terms of endoscopic characteristics,MSI-H EGCs more frequently presented with elevated pattern (OR 4.38,95% CI:2.40-8.01,P < 0.001),moderateto-severe atrophy in the surrounding mucosa (OR 1.91,95% CI:1.05-3.47,P = 0.033),antral location (OR 3.99,95% CI:2.12-7.52,P < 0.001) and synchronous lesions,compared to non-MSI-H EGCs (OR 2.65,95% CI:1.16-6.07,P = 0.021).Other significant clinicopathologic characteristics of MSI-H EGC included predominance of female sex (OR 2.77,95% CI:1.53-4.99,P < 0.001),older age (> 70 years) (OR 3.30,95% CI:1.57-6.92,P = 0.002),better histologic differentiation (OR 2.35,95% CI:1.27-4.34,P = 0.007),intestinal type by Lauren classification (OR 2.34,95% CI:1.15-4.76,P = 0.019),absence of a signet ring cell component (OR 2.44,95% CI:1.02-5.86,P = 0.046),presence of mucinous component (OR 5.06,95% CI:1.27-20.17,P = 0.022),moderate-to-severe lymphoid stromal reaction (OR 3.95,95% CI:1.59-9.80,P = 0.003),and co-existing underlying adenoma (OR 2.66,95% CI:1.43-4.95,P = 0.002).CONCLUSION:MSI-H EGC is associated with unique endoscopic and clinicopathologic characteristics including frequent presentation in protruded type,co-existing underlying adenoma,and synchronous lesions. | Jaehoon Jahng Young Hoon Youn Kwang Hyun Kim Junghwan Yu Yong Chan Lee Woo Jin Hyung Sung Hoon Noh Hyunki Kim Hoguen Kim Hyojin Park Sang In Lee | 2012 | World Journal of Gastroenterology2012，18，27： | 6 |
| 20 | Safety of endoscopic ultrasound-guided ethanol ablation for pancreatic cystic lesions: A single-center experience of 214 patients显示文摘Background:Endoscopic ultrasound-guided ethanol ablation(EUS-EA)for pancreatic cystic lesions(PCLs)has been used in recent years as a feasible treatment modality for low malignant probability PCLs or patients considered high-risk for surgery.The present study aimed to confirm the safety of EUS-EA and to find predictive factors for adverse event(AE).Methods:A retrospective review was performed from the prospectively maintained database of patients who underwent EUS-EA for PCLs from June 2006 to April 2018 at Seoul National University Hospital.The primary outcomes of the study were the rates of AEs and severe AEs by EUS-EA.The secondary outcome was the predictive factors of AEs including acute pancreatitis and abdominal pain.Results:A total of 214 patients were evaluated and the diagnoses of PCLs according to cystic fluid analysis and clinical features were as follows:serous cystic neoplasm(32.2%),mucinous cystic neoplasm(26.6%),branch duct type intraductal papillary mucinous neoplasm(BD-IPMN)(29.4%),and pseudocyst(11.7%).Three patients(1.4%)experienced severe AEs.Overall,AEs occurred in 71(33.2%)patients.BD-IPMN(OR:2.87;95%CI:1.05–7.84;P=0.040),multilocular cysts(OR:3.59;95%CI:1.09–11.85;P=0.036),suspected ethanol leakage during procedure(OR:10.68;95%CI:1.98–57.53;P=0.006),and sticky cystic fluid(OR:3.83;95%CI:1.20–12.24;P=0.024)were predictive factors for post-procedural acute pancreatitis.PCLs of uncinate process(OR:2.99;95%CI:1.22–7.35;P=0.017)and PCLs with exophytic portion(OR:3.70;95%CI:1.96–7.01;P<0.001)were predictive factors for post-procedural abdominal pain.Conclusions:EUS-EA is a safe procedure with a very low rate of severe AEs.It seems possible to predict the AEs according to the features of the procedure and PCLs. | Jin Ho Choi Sang Hyub Lee Young Hoon Choi Min Su You Bang-Sup Shin Woo Hyun Paik Ji Kon Ryu Yong-Tae Kim | 2019 | Hepatobiliary & Pancreatic Diseases International2019，18，6： | 6 |
