| 1 | Efficacy of leukocyte esterase dipstick test as a rapid test in diagnosis of spontaneous bacterial peritonitis显示文摘AIM: To evaluate the efficacy of dipstick test in diagnosis of spontaneous bacterial peritonitis (SBP) in cirrhotic patients who underwent abdominal paracentesis based on the locally available dipstick test. METHODS: There were 200 consecutive samples from cirrhotic patients who underwent abdominal paracentesis. Urine dipstick (Combur10 Test?M, Roche, Mannheim, Germany) was used as a screening test. A manual cell count with differential study was done in all samples by experienced technicians. The polymorphonuclear (PMN) cell count more than 250 cells/mm3 was used as a diagnostic cut off level. One to three plus dipstick results were used as cut off levels for a positive result. The dipstick test results had to be agreed by three experienced readers. The sensitivity, specificity, positive and negative predictive values and accuracy of two different colorimetric cut off scales (1+ and 2+) were calculated and compared. RESULTS: The prevalence of SBP diagnosed by manual cell count was 21.0%. There were 128 specimens that had a true negative result by dipstick. The sensitivity, specificity, positive and negative predictive values and accuracy of 1+ and 2+ cut off scale to diagnose SBP were 88%, 81%, 55%, 96% and 83% respectively, and 63%, 96%, 82%, 81% and 89% respectively. CONCLUSION: Dipstick test can be used as a rapid test for screening of SBP. The higher cut off colorimetric scale has a better specificity and positive predictive value but a lower sensitivity. | Rungsun Rerknimitr Worawut Rungsangmanoon Pradermchai Kongkam Pinit Kullavanijaya | 2006 | World Journal of Gastroenterology2006，12，44： | 8 |
| 2 | 国际专家组关于超声内镜引导下胰腺囊性肿瘤消融的立场声明显示文摘背景和目的最近,一些有关胰腺囊性肿瘤(pancreatic cystic neoplasms,PCNs)治疗的指南建议已经发表,但是超声内镜(endoscopic ultrasound,EUS)引导下PCNs消融的作用在这些指南中尚未明确。本文的目的是通过提出一系列临床问题并根据可获得的最佳科学证据提供答案来探讨围绕EUS引导下PCNs消融的问题。方法我们从亚洲EUS学组和一个国际专家组中招募了一个EUS引导下PCNs消融专家小组。创建了一个临床问题列表,并将每个问题分配给一个成员以产生一个陈述。然后在2016年10月至2017年10月的三次互联网会议上讨论了这些陈述。之后相互协商对这些陈述进行修改,直到取得协商一致意见。之后,将完整的陈述总结集体发送给所有小组成员,以对陈述的强度进行投票,对陈述进行分类,对证据进行分级。结果制定了关于EUS引导下PCNs的23个陈述。这些陈述涉及操作步骤、操作技术、操作前和操作后管理,并发症的管理以及手术中所需能力和培训。结论在所有内镜学会中,本共识是关于EUS引导下PCNs消融的首篇共识。有兴趣进行这项技术的临床医生应参考这些共识,未来的研究应设法解决本共识中提出的重要问题。 | Anthony Yuen-Bun Teoh DongWan Seo William Brugge John Dewitt Pradermchai Kongkam 令狐恩强(文/译) Matthew T.Moyer JiKon Ryu Khek Yu Ho 杜晨(翻译) 李惠凯(翻译) | 2019 | 中华胃肠内镜电子杂志2019，6，4： | 8 |
| 3 | Non-sequential narrow band imaging for targeted biopsy and monitoring of gastric intestinal metaplasia显示文摘AIM: To evaluate the efficacy of non-sequential narrow band imaging (NBI) for a better recognition of gastric intestinal metaplasia (GIM). METHODS: Previously diagnosed GIM patients underwent targeted biopsy from areas with and without GIM, as indicated by NBI, twice at an interval of 1 year. The authors compared the endoscopic criteria such as light blue crest (LBC), villous pattern (VP), and large long crest (LLC) with standard histology. The results from two surveillance endoscopies were compared with histology results for sensitivity, specif icity, positive predic-tive value (PPV), negative predictive value (NPV), and likelihood ratio of positive test (LR+). The number of early gastric cancer cases detected was also reported. RESULTS: NBI targeted biopsy was performed in 38 and 26 patients during the first and second surveillance endoscopies, respectively. There were 2 early gastric cancers detected in the first endoscopy. No cancer was detected from the second study. Surgical and endoscopic resections were successfully performed in each patient. Sensitivity, specifi city, PPV, NPV, and LR+ of all 3 endoscopic criteria during the first/second surveillances were 78.8%/91.3%, 82.5%/89.1%, 72.8%/77.8%, 86.8%/96.1, and 4.51/8.4, respectively. LBC provided the highest LR+ over VP and LLC. CONCLUSION: Non-sequential NBI is useful for GIM targeted biopsy. LBC provides the most sensitive reading. However, the optimal duration between two surveillances requires further study. | Rungsun Rerknimitr Boonlert Imraporn Naruemon Klaikeaw Wiriyaporn Ridtitid Sukprasert Jutaghokiat Yuwadee Ponauthai Pradermchai Kongkam Pinit Kullavanijaya | 2011 | World Journal of Gastroenterology2011，17，10： | 7 |
| 4 | Bleeding gastric varices: Results of endoscopic injection with cyanoacrylate at King Chulalongkorn Memorial Hospital显示文摘AIM: To evaluate the efficacy and safety of gastric varices injection with cyanoacrylate in patients with gastric variceal bleeding.METHODS: Twenty-four patients (15 males, 9 females) with gastric variceal bleeding underwent endoscopic treatment with cyanoacrylate injection. Successful hemostasis, rebleeding rate, and complications were retrospectively reviewed. Followed up endoscopy was performed and repeat cyanoacrylate injection was given until gastric varices were obliterated. RESULTS: Seventeen patients achieved definite hemostasis. Of these, 14 patients had primary success after initial endoscopic therapy. Ten patients developed recurrent bleeding. Repeated cyanoacrylate injection stopped rebleeding in three patients. Transjugular intrahepatic portosystemic shunt (TIPS) was performed to control rebleeding in one patient which occured after repeat endoscopic therapy. Six patients died (three from uncontrolled bleeding, two from sepsis, and one from mesenteric vein thrombosis). Minor complications occurred in 11 patients (six epigastric discomfort and five post injection ulcers). Cyanoacrylate embolism developed in two patients. One of these patients died from mesenteric vein thrombosis. The other had pulmonary embolism which resolved spontaneously. Advanced cirrhosis and hepatocellular carcinoma (HCC) were major risk factors for uncontrolled bleeding.CONCLUSION: Endoscopic treatment for bleeding gastric varices with cyanoacrylate injection is effective for immediate hemostasis. Repeat cyanoacrylate injection has a lower success rate than the initial injection.Cyanoacrylate embolism is not a common serious complication. | Phadet Noophun Pradermchai Kongkam Sutep Gonlachanvit Rungsun Rerknimitr | 2005 | World Journal of Gastroenterology2005，11，47： | 5 |
| 5 | Forward-viewing radial-array echoendoscope for staging of colon cancer beyond the rectum显示文摘AIM:To evaluate feasibility of the novel forward-viewing radial-array echoendoscope for staging of colon cancer beyond rectum as the first series.METHODS:A retrospective study with prospectively entered database.From March 2012 to February 2013,a total of 21 patients(11 men)(mean age 64.2 years)with colon cancer beyond the rectum were recruited.The novel forward-viewing radial-array echoendoscope was used for ultrasonographic staging of colon cancer beyond rectum.Ultrasonographic T and N staging were recorded when surgical pathology was used as a gold standard.RESULTS:The mean time to reach the lesion and the mean time to complete the procedure were 3.5 and 7.1min,respectively.The echoendoscope passed through the lesions in 13 patients(61.9%)and reached the cecum in 10 of 13 patients(76.9%).No adverse events were found.The lesions were located in the cecum(n=2),ascending colon(n=1),transverse colon(n=2),descending colon(n=2),and sigmoid colon(n=14).The accuracy rate for T1(n=3),T2(n=4),T3(n=13)and T4(n=1)were 100%,60.0%,84.6%and 100%,respectively.The overall accuracy rates for the T and N staging of colon cancer were 81.0%and52.4%,respectively.The accuracy rates among traversable lesions(n=13)and obstructive lesions(n=8)were 61.5%and 100%,respectively.endoscopic ultrasound and computed tomography had overall accuracy rates of 81.0%and 68.4%,respectively.CONCLUSION:The echoendoscope is a feasible staging tool for colon cancer beyond rectum.However,accuracy of the echoendoscope needs to be verified by larger systematic studies. | Pradermchai Kongkam Sittikorn Linlawan Satimai Aniwan Narisorn Lakananurak Suparat Khemnark Chucheep Sahakitrungruang Jirawat Pattanaarun Supakij Khomvilai Naruemon Wisedopas Wiriyaporn Ridtitid Manoop S Bhutani Pinit Kullavanijaya Rungsun Rerknimitr | 2014 | World Journal of Gastroenterology2014，20，10： | 5 |
| 6 | Endoscopic ultrasound elastography for solid pancreatic lesions显示文摘Elastography is one of technologies assisting diagnosis ofsolid pancreatic lesions(SPL). This technology has been previously used for measuring the stiffness of various organs based on a principle of 'harder the lesions, higher chance for malignancy'. Two elastography techniques; strain and shear wave elastography, are available. For endoscopic ultrasound(EUS), only the former is existing. To interpret results of EUS elastography for SPL, 3 methods are used:(1) pattern recognition;(2) strain ratio; and (3) strain histogram. Based on results of existing studies, these 3 techniques provide high sensitivity but low to moderate specificity and accuracy rate. This review will summarize all available information in order to update current situation of using elastography for an evaluation of SPLs to readers. | Tanyaporn Chantarojanasiri Pradermchai Kongkam | 2017 | World Journal of Gastrointestinal Endoscopy2017，9，10： | 5 |

| 9 | Differences in characteristics of colorectal neoplasm between young and elderly Thais显示文摘AIM: To analyze the differences of clinical characteristics of colorectal neoplasm including polyps between the elderly and young Thai patients.METHODS: Colonoscopy database from December 2000 to October 2004 was retrospectively analyzed. There were 1822 eligible patients who underwent colonoscopy (with a mean age of 56.6 years). Patients were classified into two groups: the older age group (aged ≥ 60 years; n = 989) and the younger age group (aged < 60 years; n = 833). Data were recorded on age, colonoscopic indications, tumor location, colonoscopic findings and their related histological findings. RESULTS: Colorectal malignancy related lesions were more often found in the older age group (21%) than in the younger age group (12%). Left-sided lesions were detected more commonly than right-sided in both age groups in approximately two-thirds of all cases. Hematochezia showed greater association with left-sided lesions in the elderly. No relationship was found between age and neoplasm staging and severity.CONCLUSION: The chance of detecting colorectal neoplasm by colonoscopy was higher in the elderly than in the young Thais. However, both groups had the lesions predominantly located in the left side. | Rungsun Rerknimitr Winudda Ratanapanich Pradermchai Kongkam Pinit Kullavanijaya | 2006 | World Journal of Gastroenterology2006，12，47： | 1 |
