1Expression of heat shock proteins (HSP27, HSP60, HSP70, HSP90, GRP78, GRP94) in hepatitis B virus-related hepatocellular carcinomas and dysplastic nodules显示文摘AIM: Expression of heat shock proteins (HSPs) is frequently up-regulated in hepatocellular carcinoma (HCC), which evolves from dysplastic nodule (DN) and early HCC to advanced HCC. However, little is known about the differential expression of HSPs in multistep hepatocarcinogenesis. It was the purpose of this study to monitor the expression of HSPs in multistep hepatocarcinogenesis and to evaluate their prognostic significance in hepatitis B virus (HBV)related HCC.METHODS: Thirty-eight HCC and 19 DN samples were obtained from 52 hepatitis B surface antigen-positive Korean patients. Immunohistochemical and dot immunoblot analyses of HSP27, HSP60, HSP70, HSP90, glucoseregulated protein (GRP)78, and GRP94 were performed and their expression at different stages of HCC development was statistically analyzed.RESULTS: Expression of HSP27, HSP70, HSP90, GRP78, and GRP94 increased along with the stepwise progression of hepatocarcinogenesis. Strong correlation was found only in GRP78 (Spearman's r= 0.802). There was a positive correlation between the expressions of GRP78, GRP94, HSP90, or HSP70 and prognostic factors of HCC. Specifically, the expression of GRP78, GRP94, or HSP90 was associated significantly with vascular invasion and intrahepatic metastasis.CONCLUSION: The expressions of HSPs are commonly up-regulated in HBV-related HCCs and GRP78 might play an important role in the stepwise progression of HBVrelated hepatocarcinogenesis. GRP78, GRP94, and HSP90 may be important prognostic markers of HBV-related HCC, strongly suggesting vascular invasion and intrahepatic metastasis.Seung Oe Lim Sung Gyoo Park Jun-Hi Yoo Young Min Park Hie-Joon Kim Kee-Taek Jang Jae Won Cho Byung Chul Yoo Gu-Hung Jung Cheol Keun Park 2005World Journal of Gastroenterology2005,11,14:62

3Long-term result of endoscopic Histoacryl (N-butyl-2-cyanoacrylate)injection for treatment of gastric varices显示文摘AIM:To evaluate the long-term efficacy and safety of endoscopic obliteration with Histoacryl  for treatment of gastric variceal bleeding and prophylaxis.METHODS:Between January 1994 and March 2010 at SoonChunHyang University Hospital,a total of 127 patients with gastric varices received Histoacryl  injections endoscopically.One hundred patients underwent endoscopic Histoacryl  injections because of variceal bleeding,the other 27 patients received such injections as a prophylactic procedure.RESULTS:According to Sarin classification,56 patients were GOV1,61 patients were GOV2 and 10 patients were IGV.Most of the varices were large(F2 or F3,111 patients).The average volume of Histoacryl  per each session was 1.7±1.3 cc and mean number of sessions was 1.3±0.6.(1 session-98 patients,2 sessions-25 patients,≥3 sessions-4 patients).Twenty-seven patients with high risk of bleeding(large or fundal or RCS+or Child C) received Histoacryl  injection as a primary prophylactic procedure.In these patients,hepatitis B virus was the major etiology of cirrhosis,25 patients showed GOV1 or 2(92.6%)and F2 or F3 accounted for 88.9%(n=24).The rate of initial hemostasis was 98.4%and recurrent bleeding within one year occurred in 18.1%of patients.Successful hemostasis during episodes of rebleeding was achieved in 73.9%of cases.Median survival was 50 mo (95%CI 30.5-69.5).Major complications occurred in 4 patients(3.1%).The rebleeding rate in patients with hepatocellular carcinoma or GOV2 was higher than in those with other conditions.None of the 27 subjects who were treated prophylactically experienced treatment-related complications.Cumulative survival rates of the 127 patients at 6 mo,1,3,and 5 years were 92.1%,84.2%,64.2%,and 45.3%,respectively.The 6 mo cumulative survival rate of the 27 patients treated prophylactically was 75%.CONCLUSION:Histoacryl  injection therapy is an effective treatment for gastric varices and also an effective prophylactic treatment of gastric varices which carry high risk of bleeding.Eun Jung Kang Soung Won Jeong Jae Young Jang Joo Young Cho Sae Hwan Lee Hyun Gun Kim Sang Gyune Kim Young Seok Kim Young Koog Cheon Young Deok Cho Hong Soo Kim Boo Sung Kim 2011World Journal of Gastroenterology2011,17,11:41
4Worldwide experiences of endoscopic submucosal dissection:Not just Eastern acrobatics显示文摘The high incidence of gastric cancer has led to the initiation of cancer screening programs.As a result,the number of early gastric cancer cases has increased and consequentially,the cancer mortality rate has decreased.Moreover,the development of minimally invasive endoscopic treatment has been introduced for these early lesions.Endoscopic submucosal dissection(ESD) is now recognized as one of the preferred treatment modalities for premalignant gastrointestinal epithelial lesions and early gastric cancer without lymph node metastasis.We review the results of ESD including experiences in Japan and Korea,as well as western countries.Kwang Bum Cho Won Joong Jeon Jae J Kim 2011World Journal of Gastroenterology2011,17,21:48
5Overexpression of S100A4 is closely associated with progression of colorectal cancer显示文摘AIM: To investigate whether S100A4 played an important role in the development or progression of colorectal cancer.METHODS: A total of 124 colorectal adenocarcinoma tissue specimens were analyzed by immunohistochemistry for the expression of S100A4 protein and subsequently investigated for the gene mutations in the coding region of S100A4 gene. The specimens were collected over a 3-year period in the laboratories at our large teaching hospital in Seoul, Republic of Korea.RESULTS: Normal colonic epithelium either failed to express or showed focal weak expression of S100A4. Moderate to strong cytoplasmic expression of S100A4 was seen in 69(55.6%) of the 124 colorectal carcinoma tissue specimens.S100A4 expression was detected in 43 (69.4%) of 62specimens with lymph node metastasis. Statistically,overexpression of S100A4 was significantly associated with Dukes' stage and lymph node metastasis. Nuclear staining was also observed in 24 (19.4%) of 124 samples and closely associated with Dukes' stage. However, there was no significant correlation between overexpression of S100A4and other investigated clinico-pathologic parameters,including tumor localization, tumor size, and survival period.In mutational analysis, no gene mutation was found in the analyzed genomic area of colorectal cancer.CONCLUSION: Overexpression of 5100A4 may be closely related with the aggressiveness of colorectal carcinoma.Yong-Gu Cho Chang-Jae Kim Suk-Woo Nam Shin-Hee Yoon Sug-Hyung Lee Nam-Jin Yoo Jung-Young Lee Won-Sang Park 2005World Journal of Gastroenterology2005,11,31:40

7Role of diffusion-weighted magnetic resonance imaging in the differential diagnosis of focal hepatic lesions显示文摘AIM:To evaluate the utility of diffusion-weighted im-aging(DWI)in screening and differential diagnosis of benign and malignant focal hepatic lesions.METHODS:Magnetic resonance imaging(MRI)ex-aminations were performed using the Signa Excite Xl Twin Speed 1.5T system(GE Healthcare,Milwaukee,WI,USA).Seventy patients who had undergone MRI of the liver [29 hepatocellular carcinomas(HCC),four cholangiocarcinomas,34 metastatic liver cancers,10 hemangiomas,and eight cysts] between April 2004 and August 2008 were retrospectively evaluated.Visu-alization of lesions,relative contrast ratio(RCR),and apparent diffusion coefficient(ADC)were compared between benign and malignant lesions on DWI.Su-perparamagnetic iron oxide(SPIO)was administered to 59 patients,and RCR was compared pre-and post-administration.RESULTS:DWI showed higher contrast between ma-lignant lesions(especially in multiple small metastatic cancers)and surrounding liver parenchyma than did contrast-enhanced computed tomography.ADCs(mean ± SD × 10-3 mm2/s)were signif icantly lower(P < 0.05)in malignant lesions(HCC:1.31 ± 0.28 and liver me-tastasis:1.11 ± 0.22)and were signifi cantly higher in benign lesions(hemangioma:1.84 ± 0.37 and cyst:2.61 ± 0.45)than in the surrounding hepatic tissues.RCR between malignant lesions and surrounding he-patic tissues signifi cantly improved after SPIO adminis-tration,but RCRs in benign lesions were not improved.CONCLUSION:DWI is a simple and sensitive method for screening focal hepatic lesions and is useful for dif-ferential diagnosis.Naoto Koike Akihiro Cho Katsuhiro Nasu Kazuhiko Seto Shigeyuki Nagaya Yuji Ohshima Nobuhiro Ohkohchi 2009World Journal of Gastroenterology2009,15,46:38
8Risk factors for complications associated with upper gastrointestinal foreign bodies显示文摘AIM: To investigate predictive risk factors associated with complications in the endoscopic removal of foreign bodies from the upper gastrointestinal tract.METHODS: We retrospectively reviewed the medical records of 194 patients with a diagnosis of foreign body impaction in the upper gastrointestinal tract,confirmed by endoscopy,at two university hospital in South Korea.Patient demographic data,including age,gender,intention to ingestion,symptoms at admission,and comorbidities,were collected.Clinical features of the foreign bodies,such as type,size,sharpness of edges,number,and location,were analyzed.Endoscopic data those were analyzed included duration of foreign body impaction,duration of endoscopic performance,endoscopic device,days of hospitalization,complication rate,30-d mortality rate,and the number of operationsrelated to foreign body removal.RESULTS: The types of upper gastrointestinal foreign bodies included fish bones,drugs,shells,meat,metal,and animal bones.The locations of impacted foreign bodies were the upper esophagus(57.2%),mid esophagus(28.4%),stomach(10.8%),and lower esophagus(3.6%).The median size of the foreign bodies was 26.2 ± 16.7 mm.Among 194 patients,endoscopic removal was achieved in 189,and complications developed in 51 patients(26.9%).Significant complications associated with foreign body impaction and removal included deep lacerations with minor bleeding(n = 31,16%),ulcer(n = 11,5.7%),perforation(n = 3,1.5%),and abscess(n = 1,0.5%).Four patients underwent operations because of incomplete endoscopic foreign body extraction.In multivariate analyses,risk factors for endoscopic complications and failure were sharpness(HR = 2.48,95%CI: 1.07-5.72; P = 0.034) and a greater than 12-h duration of impaction(HR = 2.42,95%CI: 1.12-5.25,P = 0.025).CONCLUSION: In cases of longer than 12 h since foreign body ingestion or sharp-pointed objects,rapid endoscopic intervention should be provided in patients with ingested foreign bodies.Kyong Hee Hong Yoon Jae Kim Jae Hak Kim Song Wook Chun Hee Man Kim Jae Hee Cho 2015World Journal of Gastroenterology2015,21,26:35
9Comparison of scoring systems in predicting the severity of acute pancreatitis显示文摘AIM:To investigate the prognostic usefulness of several existing scoring systems in predicting the severity of acute pancreatitis(AP).METHODS:We retrospectively analyzed the prospectively collected clinical database from consecutive patients with AP in our institution between January 2011 and December 2012.Ranson,Acute Physiology and Chronic Health Evaluation(APACHE)-Ⅱ,and bedside index for severity in acute pancreatitis(BISAP)scores,and computed tomography severity index(CTSI)of all patients were calculated.Serum C-reactive protein(CRP)levels were measured at admission(CRPi)and after 24h(CRP24).Severe AP was defined as persistent organ failure for more than 48 h.The predictive accuracy of each scoring system was measured by the area under the receiver-operating curve(AUC).RESULTS:Of 161 patients,21(13%)were classified as severe AP,and 3(1.9%)died.Statistically significant cutoff values for prediction of severe AP were Ranson≥3,BISAP≥2,APACHE-Ⅱ≥8,CTSI≥3,and CRP24≥21.4.AUCs for Ranson,BISAP,APACHE-Ⅱ,CTSI,and CRP24 in predicting severe AP were 0.69(95%CI:0.62-0.76),0.74(95%CI:0.66-0.80),0.78(95%CI:0.70-0.84),0.69(95%CI:0.61-0.76),and0.68(95%CI:0.57-0.78),respectively.APACHE-Ⅱdemonstrated the highest accuracy for prediction of severe AP,however,no statistically significant pairwise differences were observed between APACHE-Ⅱand the other scoring systems,including CRP24.CONCLUSION:Various scoring systems showed similar predictive accuracy for severity of AP.Unique models are needed in order to achieve further improvement of prognostic accuracy.Joon Hyun Cho Tae Nyeun Kim Hyun Hee Chung Kook Hyun Kim 2015World Journal of Gastroenterology2015,21,8:35
10Effects of Cordyceps militaris extract on angiogenesis and tumor growth显示文摘AIM: To evaluate the effects of Cordyceps militaris extract (CME) on angiogenesis and tumor growth. METHODS:Human umbilical vein endothelial cells (HUVEC), HT1080, and B16-F10 cells were used. DNA fragment, angio-genic related gene expressions (MMPs, bFGF, VEGF, etc), capillary tube formation, wound healing in vitro, tumorgrowth in vivo were measured. RESULTS: CME inhibited growth of HUVECs and HT1080 (P<0.01). CME 100and 200 mg/L reduced MMP-2 gene expression in HT1080 cells by 6.0 % and 22.9 % after 3-h and 14.9 % and32.8 % after 6-h treatment. CME did not affect MMP-9 gene expression in B16-F10 melanoma cells. CME 100 and200 mg/L also reduced bFGF gene expression in HUVECs by 22.2 % and 41.3 %. CME inhibited tube formation ofendothelial cells in vitro and in vivo. CME repressed the growth of B16-F10 melanoma cells in mice compared withcontrol group (P<0.05). CONCLUSION: CME has antiangiogenetic properties.Hwa-seung YOO Jang-woo SHIN Jung-hyo CHO Chang-gue SON Yeon-weol LEE Sang-yong PARK Chong-kwan CHO 2004Acta Pharmacologica Sinica2004,25,5:40
11Risk factors affecting pancreatic fistulas after pancreaticoduodenectomy显示文摘AIM: To analyze the risk factors of pancreatic leakage after pancreaticoduodenectomy.METHODS: We retrospectively reviewed 172 consecutive patients who had undergone pancreatico-duodenectomy at Inha University Hospital between April 1996 and March 2006. We analyzed the pancreatic fistula rate according to the clinical characteristics, the pathologic and laboratory findings, and the anastomotic methods.RESULTS: The incidence of developing pancreatic fistulas in patients older than 60 years of age was 21.7% (25/115), while the incidence was 8.8% (5/57) for younger patients; the difference was significant (P = 0.03). Patients with a dilated pancreatic duct had a lower rate of post-operative pancreatic fistulas than patients with a non-dilated duct (P = 0.001). Other factors, including clinical features, anastomotic methods, and pathologic diagnosis, did not show any statistical difference. CONCLUSION: Our study demonstrated that pancreatic fistulas are related to age and a dilated pancreatic duct. The surgeon must take these risk factors into consideration when performing a pancre-aticoduodenectomy.Yun-Mee Choe Keon-Young Lee Cheong-Ah Oh Joung-Bum Lee Sun Keun Choi Yoon-Seok Hur Sei-Joong Kim Young Up Cho Seung-Ik Ahn Kee-Chun Hong Seok-Hwan Shin Kyung-Rae Kim 2008World Journal of Gastroenterology2008,14,45:32
12Small sphincterotomy combined with endoscopic papillary large balloon dilation versus sphincterotomy显示文摘AIM:To compare small sphincterotomy combined with endoscopic papillary large balloon dilation(SES+ ELBD)and endoscopic sphincterotomy(EST)for large bile duct stones. METHODS:We compared prospectively SES+ELBD (group A,n=27)with conventional EST(group B, n=28)for the treatment of large bile duct stones(≥ 15 mm).When the stone could not be removed with a normal basket,mechanical lithotripsy was performed. We compared the rates of complete stone removal with one session and application of mechanical lithotripsy. RESULTS:No significant differences were observed in the mean largest stone size(A:20.8 mm,B:21.3 mm), bile duct diameter(A:21.4 mm,B:20.5 mm),number of stones(A:2.2,B:2.3),or procedure time(A:18 min, B:19 min)between the two groups.The rates of complete stone removal with one session was 85%in group A and 86%in group B(P=0.473).Mechanical lithotripsy was required for stone removal in nine of 27 patients(33%)in group A and nine of 28 patients (32%,P=0.527)in group B.CONCLUSION:SES+ELBD did not show significant benefits compared to conventional EST,especially for the removal of large(≥15 mm)bile duct stones.Hyun Gun Kim Young Koog Cheon Young Deok Cho Jong Ho Moon Do Hyun Park Tae Hoon Lee Hyun Jong Choi Sang-Heum Park Joon Seong Lee Moon Sung Lee 2009World Journal of Gastroenterology2009,15,34:34
13Model-Based Integrated Methods for Quantitative Estimation of Soil Salinity from Hyperspectral Remote Sensing Data:A Case Study of Selected South African Soils显示文摘Soil salinization is a land degradation process that leads to reduced agricultural yields. This study investigated the method that can best predict electrical conductivity (EC) in dry soils using individual bands, a normalized difference salinity index (NDSI), partial least squares regression (PLSR), and bagging PLSR. Soil spectral reflectance of dried, ground, and sieved soil samples containing varying amounts of EC was measured using an ASD FieldSpec spectrometer in a darkroom. Predictive models were computed using a training dataset. An independent validation dataset was used to validate the models. The results showed that good predictions could be made based on bagging PLSR using first derivative reflectance (validation R2 = 0.85), PLSR using untransformed reflectance (validation R2 = 0.70), NDSI (validation R2 = 0.65), and the untransformed individual band at 2257 nm (validation R2 = 0.60) predictive models. These suggested the potential of mapping soil salinity using airborne and/or satellite hyperspectral data during dry seasons.Z. E. MASHIMBYE M. A. CHO J. P. NELL W. P. DE CLERCQ A. VAN NIEKERK D. P.

15MicroRNAs in the prognosis and therapy of colorectal cancer: From bench to bedside显示文摘MicroRNAs(miRNAs) are small, single-stranded, noncoding RNAs that can post-transcriptionally regulate the expression of various oncogenes and tumor suppressor genes. Dysregulated expression of many miRNAs have been shown to mediate the signaling pathways critical in the multistep carcinogenesis of colorectal cancer(CRC). MiR NAs are stable and protected from RNase-mediated degradation, thereby enabling its detection in biological fluids and archival tissues for biomarker studies. This review focuses on the role and application of miRNAs in the prognosis and therapy of CRC. While stage Ⅱ CRC is potentially curable by surgical resection, a significant percentage of stage Ⅱ CRC patients do develop recurrence. MiRNA biomarkers may be used to stratify such high-risk population for adjuvant chemotherapy to provide better prognoses. Growing evidence also suggests that miRNAs are involved in the metastatic process of CRC. Certain of these miRNAs may thus be used as prognostic biomarkers to identify patients more likely to have micro-metastasis, who could be monitored more closely after surgery and/or given more aggressive adjuvant chemotherapy. Intrinsic and acquired resistance to chemotherapy severely hinders successful chemotherapy in CRC treatment. Predictive miRNA biomarkers for response to chemotherapy may identify patients who will benefit the most from a particular regimen and also spare the patients from unnecessary side effects. Selection of patients to receive the new targeted therapy is becoming possible with the use of predictive miRNA biomarkers. Lastly, forced expression of tumor suppressor miRNA or silencing of oncogenic miRNA in tumors by gene therapy can also be adopted to treat CRC alone or in combination with other chemotherapeutic drugs.Kenneth KW To Christy WS Tong Mingxia Wu William CS Cho 2018World Journal of Gastroenterology2018,24,27:29
16Mechanisms of drug resistance in colon cancer and its therapeutic strategies显示文摘Drug resistance develops in nearly all patients with colon cancer, leading to a decrease in the therapeutic efficacies of anticancer agents. This review provides an up-to-date summary on over-expression of ATPbinding cassette(ABC) transporters and evasion of apoptosis, two representatives of transport-based and non-transport-based mechanisms of drug resistance, as well as their therapeutic strategies. Different ABC transporters were found to be up-regulated in colon cancer, which can facilitate the efflux of anticancer drugs out of cancer cells and decrease their therapeutic effects. Inhibition of ABC transporters by suppressing their protein expressions or co-administration of modulators has been proven as an effective approach to sensitize drug-resistant cancer cells to anticancer drugs in vitro. On the other hand, evasion of apoptosis observed in drug-resistant cancers also results in drug resistance to anticancer agents, especially to apoptosis inducers. Restoration of apoptotic signals by BH3 mimetics or epidermal growth factor receptor inhibitors and inhibition of cancer cell growth by alternative cell death pathways, such as autophagy, are effective means to treat such resistant cancer types. Given that the drug resistance mechanisms are different among colon cancer patients and may change even in a single patient at different stages, personalized and specific combination therapy is proposed to be more effective and safer for the reversal of drug resistance in clinics.Tao Hu Zhen Li Chun-Ying Gao Chi Hin Cho 2016World Journal of Gastroenterology2016,22,30:29
17Pre-operative factors that can predict neoplastic polypoid lesions of the gallbladder显示文摘AIM:To investigate the preoperative factors that can predict neoplastic polypoid lesions of the gallbladder(PLGs) as well as malignant PLGs.METHODS:A retrospective analysis was conducted on the 210 consecutively enrolled patients who underwent cholecystectomy due to a PLG larger than 10 mm,as was determined by preoperative trans-abdominal ultrasonography or endoscopic ultrasonography.We ana-lyzed the medical,laboratory,radiologic data and the pathologic results.RESULTS:In 210 cases,146 had non-neoplastic polyps(69.5%) and 64 cases were neoplastic polyps(30.5%).An older age(≥ 65 years),the presence of diabetes mellitus(DM) and the size of polyp(≥ 15 mm) were revealed to be independent predictive variables for neoplastic polyps with odd ratios(OR) of 2.27(P = 0.044),2.64(P = 0.021) and 4.94(P < 0.01),respectively.Among the neoplastic PLGs,an older age(≥ 65 years),the presence of DM and polyp size(≥ 15 mm) were associated with malignancy with ORs of 4.97(P = 0.005),6.13(P = 0.001) and 20.55(P < 0.001),respectively.CONCLUSION:Among patients with PLGs larger than 10 mm in size,higher risk groups such as elderly patients more than 65 years old,those with DM or a large polyp size(≥ 15 mm) should be managed by cholecystectomy.Byung Hyo Cha Jin-Hyeok Hwang Sang Hyub Lee Jang Eon Kim Jai Young Cho Haeryoung Kim So Yeon Kim 2011World Journal of Gastroenterology2011,17,17:27

19Photodynamic therapy prolongs metal stent patency in patients with unresectable hilar cholangiocarcinoma显示文摘AIM:To evaluate the effect of photodynamic therapy (PDT) on metal stent patency in patients with unresectable hilar cholangiocarcinoma (CC). METHODS:This was a retrospective analysis of patients with hilar CC referred to our institution from December, 1999 to January, 2011. Out of 232 patients, thirty-three patients with unresectable hilar CC were treated. Eighteen patients in the PDT group were treated with uncovered metal stents after one session of PDT. Fifteen patients in the control group were treated with metal stents alone. Porfimer sodium (2 mg/kg) was administered intravenously to PDT patients. Fortyeight hours later, PDT was administered using a diffusing fiber that was advanced across the tumor by either endoscopic retrograde cholangiopancreatography or percutaneous cholangiography. After performance of PDT, uncovered metal stents were inserted to ensure adequate decompression and bile drainage. Patient survival rates and cumulative stent patency were calculated using Kaplan-Meier analysis with the log-rank test. RESULTS:The PDT and control patients were comparable with respect to age, gender, health status, pretreatment bilirubin, and hilar CC stage. When compared to control, the PDT group was associated with significantly prolonged stent patency (median 244 ± 66 and 177 ± 45 d, respectively, P = 0.002) and longer patient survival (median 356 ± 213 and 230 ± 73 d, respectively, P = 0.006). Early complication rates were similar between the groups (PDT group 17%, control group 13%) and all patients were treated conservatively. Stent malfunctions occurred in 14 PDT patients (78%) and 12 control patients (80%). Of these 26 patients, twenty-two were treated endoscopically and four were treated with external drainage. CONCLUSION:Metal stenting after one session of PDT may be safe with acceptable complication rates. The PDT group was associated with a significantly longer stent patency than the control group in patients with unresectable hilar CC.Tae Yoon Lee Young Koog Cheon Chan Sup Shim Young Deok Cho 2012World Journal of Gastroenterology2012,18,39:28
20Limited endoscopic sphincterotomy plus large balloon dilation for choledocholithiasis with periampullary diverticula显示文摘AIM: To investigate the effectiveness and safety of limited endoscopic sphincterotomy (EST) plus large balloon dilation (LBD) for removing choledocholithiasis in patients with periampullary diverticula (PAD). METHODS: A total of 139 patients with common bile duct (CBD) stones were treated with LBD (10-20 mm balloon diameter) after limited EST. Of this total, 73 patients had PAD and 66 patients did not have PAD (controls). The results of stone removal and complications were retrospectively evaluated. RESULTS: There were no significant differences between the PAD and the control groups in overall successful stone removal (94.5% vs 93.9%), stone removal in first session (69.9% vs 81.8%), mechanical lithotripsy (12.3% vs 13.6%), and complications (11.0% vs 7.6%). Clinical outcomes were also similar between the types of PAD, but the rate of stone removal in first session and the number of sessions were significantly lower and more frequent, respectively, in type B PAD (papilla located near the diverticulum) than controls [23/38 (60.5%) vs 54/66 (81.8%), P = 0.021; and 1 (1-2) vs 1 (1-3), P = 0.037, respectively] and the frequency of pancreatitis was significantly higher in type A PAD (papilla located inside or in the margin of the diverticulum) than in controls (16.1% vs 3.0%, P = 0.047). CONCLUSION: Limited EST plus LBD was an effective and safe procedure for removing choledocholithiasis in patients with PAD. However, some types of PAD should be managed with caution.Hyung Wook Kim Dae Hwan Kang Cheol Woong Choi Jong Hwan Park Jin Ho Lee Min Dae Kim Il Doo Kim Ki Tae Yoon Mong Cho Ung Bae Jeon Suk Kim Chang Won Kim Jun Woo Lee 2010World Journal of Gastroenterology2010,16,34:26
