| 1 | Recurrence after endoscopic piecemeal mucosal resection for large sessile colorectal polyps显示文摘AIM: To evaluate the safety and outcomes of endoscopic piecemeal mucosal resection (EPMR) for large sessile colorectal polyps. METHODS: The patients enrolled in this study were 47 patients with 50 large sessile polyps (diameter, 2 cm or greater) who underwent EPMR using a submucosal saline injection technique between December 2002 and October 2005. All medical records, including characteristics of the patients and polyps, complications, and recurrences, were retrospectively reviewed. The first follow-up endoscopic examination was performed at 3-6 mo after initial endoscopic resection, and the second at 12 mo postEPMR. Subsequent surveillance colonoscopic examinations were individualized, taking risk factors into account. RESULTS: The patients were 23 men and 24 women,with a mean age of 60 years. Mean polyp size was 30.1 mm. Of 50 polyps identified, 34 (68%) were benign and 16 (32%) were malignant. There were 6 (12%) cases with EPMR-related bleeding: 5 intra-procedural and 1 early post-procedural bleeding. All bleeding episodes were managed by endoscopic clipping or argon beam coagulation. There were no perforations. Recurrence was identified in 5 cases (12.2%): 4 local recurrences detected at 3 mo post-EPMR and 1 local recurrence detected at 14 mo post-EPMR. The recurrence rate after EPMR was 3.1% for benign polyps and 33.3% for malignant polyps (P < 0.05). Median follow-up time was 37 mo. CONCLUSION: EPMR is safe, but should be applied carefully in malignant polyps. Close follow-up endoscopic examinations are necessary for early detection of recurrence. | Guh Jung Seo Dae Kyung Sohn Kyung Su Han Chang Won Hong Byung Chang Kim Ji Won Park Hyo Seong Choi Hee Jin Chang Jae Hwan Oh | 2010 | World Journal of Gastroenterology2010，16，22： | 17 |

| 3 | Predictors for difficult cecal insertion in colonoscopy: The impact of obesity indices显示文摘AIM To identify the factors influencing cecal insertion time(CIT) and to evaluate the effect of obesity indices on CIT. METHODS We retrospectively reviewed the data for participants who received both colonoscopy and abdominal computed tomography(CT) from February 2008 to May 2008 as part of a comprehensive health screening program. Age, gender, obesity indices [body mass index(BMI), waist-to-hip circumference ratio(WHR), waist circumference(WC), visceral adipose tissue(VAT)volume and subcutaneous adipose tissue(SAT) volume on abdominal CT], history of prior abdominal surgery, constipation, experience of the colonoscopist, quality of bowel preparation, diverticulosis and time required to reach the cecum were analyzed. CIT was categorized as longer than 10 min(prolonged CIT) and shorter than or equal to 10 min, and then the factors that required a CIT longer than 10 min were examined.RESULTS A total of 1678 participants were enrolled. The mean age was 50.42 ± 9.931 years and 60.3% were men. The mean BMI, WHR, WC, VAT volume and SAT volume were 23.92 ± 2.964 kg/m2, 0.90 ± 0.076, 86.95 ± 8.030 cm, 905.29 ± 475.220 cm3 and 1707.72 ± 576.550 cm3, respectively. The number of patients who underwent abdominal surgery was 268(16.0%). Colonoscopy was performed by an attending physician alone in 61.9% of cases and with the involvement of a fellow in 38.1% of cases. The median CIT was 7 min(range 2-56 min, IQR 5-10 min), and mean CIT was 8.58 ± 5.291 min. Being female, BMI, VAT volume and involvement of fellow were significantly associated with a prolonged CIT in univariable analysis. In multivariable analysis, being female(OR = 1.29, P = 0.047), lower BMI(< 23 kg/m2)(OR = 1.62, P = 0.004) or higher BMI(≥ 25 kg/m2)(OR = 1.80, P < 0.001), low VAT volume(< 500 cm3)(OR = 1.50, P = 0.013) and fellow involvement(OR = 1.73, P < 0.001) were significant predictors of prolonged CIT. In subgroup analyses for gender, lower BMI or higher BMI and fellow involvement were predictors for prolonged CIT in both genders. However, low VAT volume was associated with prolonged CIT in only women(OR = 1.54, P = 0.034).CONCLUSION Being female, having a lower or higher BMI than the normal range, a low VAT volume, and fellow involvement were predictors of a longer CIT. | Soo Yun Moon Byung Chang Kim Dae Kyung Sohn Kyung Su Han Bun Kim Chang Won Hong Bum Joon Park Kum Hei Ryu Ji Hyung Nam | 2017 | World Journal of Gastroenterology2017，23，13： | 3 |

| 6 | Pembrolizumab-induced psoriatic arthritis treated with disease-modifying anti-rheumatic drugs in a patient with gastric cancer:A case report显示文摘BACKGROUND Immune checkpoint inhibitor(ICI)-induced rheumatic immune-related adverse events(ir AEs)have been infrequently reported,and the treatment of severe or refractory arthritis as ir AEs has not been established yet.CASE SUMMARY The patient was a 67-year-old man with a history of well-controlled foot psoriasis who presented with polyarthralgia.He had received pembrolizumab for metastatic gastric adenocarcinoma 2 mo previously.Physical examination revealed erythematous swelling in the distal interphalangeal joints,left shoulder,and both knees.He had plaque psoriasis with psoriatic nail dystrophy and dactylitis in the distal joints of the fingers and toes.Inflammatory markers including C-reactive protein and erythrocyte sedimentation rate were elevated but rheumatoid factor and anticyclic citrullinated peptide antibody were negative.The patient was diagnosed with psoriatic arthritis(PsA)and started on methylprednisolone 1 mg/kg/day after pembrolizumab discontinuation.However,despite 1 wk of methylprednisolone treatment,PsA worsened;hence,leflunomide and methotrexate were started.After 4 wk of steroid treatment,PsA worsened and improved repeatedly with steroid tapering.Therefore,the therapy was intensified to include etanercept,a tumor necrosis factor inhibitor,which ultimately resulted in adequate PsA control.CONCLUSION This is the first report of ICI-induced PsA in a gastric cancer patient.Some rheumatic ir AEs with refractory severe arthritis may require disease-modifying anti-rheumatic drugs and long-term management. | Sehan Kim Jong Hee Sun Hongsik Kim Hee Kyung Kim Yaewon Yang Jun Su Lee In Ah Choi Hye Sook Han | 2023 | World Journal of Clinical Cases2023，11，1： | 1 |

| 10 | Gastric ischemia after epinephrine injection in a patient with liver cirrhosis显示文摘Endoscopic epinephrine injection is relatively easy,quick and inexpensive.Furthermore,it has a low rate of com-plications,and it is widely used for the management of nonvariceal upper gastrointestinal bleeding.There have been several case reports of gastric ischemia after en-doscopic injection therapy.Inadvertent intra-arterial in-jection may result in either spasm or thrombosis,leading to subsequent tissue ischemia or necrosis,although the stomach has a rich vascular supply and the vascular reserve of the intramural anastomosis.In addition to endoscopic injection therapy,smoking,hypertension and atherosclerosis are risk factors of gastric ischemia. We report a case of gastric ischemia after submucosal epinephrine injection in a 51-year-old woman with hy-pertension and liver cirrhosis. | Su Young Kim Seung-Hee Han Kyung Han Kim Sang Ock Kim Sang-Young Han Sung-Wook Lee Yang Hyun Baek | 2013 | World Journal of Gastroenterology2013，19，3： | 0 |
