Publication Endoscopic Submucosal Dissection Outcomes for Gastroesophageal Tumors in Low Volume Units: A Multicenter Survey(Hindawi Publishing Corporation, 2016) ;Najib Azmi A. ;Khor C.J.L. ;Ho K.-Y. ;Pittayanon R. ;Rerknimitr R. ;Ratanachu-Ek T. ;Koay D.S.C. ;Koh J.C. ;Ho S.-H. ;Goh K.-L. ;Mahadeva S. ;Faculty of Medicine and Health Sciences ;University of Malaya (UM) Medical Center ;Universiti Sains Islam Malaysia (USIM) ;Singapore General Hospital ;National University Hospital ;Chulalongkorn University HospitalRajavithi HospitalBackground and Aims. Endoscopic submucosal dissection (ESD) outcomes have traditionally been reported from high volume centers in East Asia. Data from low volume centers in other parts of Asia remain sparse. Methods. A retrospective survey with a structured questionnaire of 5 tertiary centers in 3 countries in South East Asia was conducted. Details of training and clinical outcomes of ESD cases, with follow-up data from these centers, were analyzed. Results. Seven endoscopists from the 5 centers performed a total of 35 cases of ESD in the upper gastrointestinal tract (UGIT) over a 6-year duration. Details of the lesions excised were as follows: median size was 20 mm, morphologically 20 (68.6%) were flat/depressed and 6 (17.1%) were submucosal, and histologically 27 (77.1%) were neoplastic. The median duration of ESD procedures was 105 minutes, with an en-bloc resection rate of 91.4%. There was 1 (2.9%) case of delayed bleeding, but no perforation nor mortality in any of the cases. The recurrence rate after ESD was 5.7%. A prolonged ESD duration was influenced by a larger size of lesion (25 mm, p=0.02) but not by factors related to the training experience of endoscopists. Conclusions. ESD in the UGIT is feasible and safe in low volume centers in Asia. � 2016 Ahmad Najib Azmi et al. - Some of the metrics are blocked by yourconsent settings
Publication Fatal infections in older patients with inflammatory bowel disease on anti-tumor necrosis factor therapy(Korean Association for the Study of Intestinal Diseases, 2017) ;Lee W.-S. ;Azmi N. ;Ng R.-T. ;Ong S.-Y. ;Ponnampalavanar S.S.L. ;Mahadeva S. ;Hilmi I. ;Faculty of Medicine and Health Sciences ;University of Malaya (UM)Universiti Sains Islam Malaysia (USIM)Anti-tumor necrosis factor (anti-TNF) is highly effective in inflammatory bowel disease (IBD); however, it is associated with an increased risk of infections, particularly in older adults. We reviewed 349 patients with IBD, who were observed over a 12-month period, 74 of whom had received anti-TNF therapy (71 patients were aged < 60 years and 3 were aged ?60 years). All the 3 older patients developed serious infectious complications after receiving anti-TNFs, although all of them were also on concomitant immunosuppressive therapy. One patient developed disseminated tuberculosis, another patient developed cholera diarrhea followed by nosocomial pneumonia, while the third patient developed multiple opportunistic infections (Pneumocystis pneumonia, cryptococcal septicemia and meningitis, Klebsiella septicemia). All 3 patients died within 1 year from the onset of the infection(s). We recommend that anti-TNF, especially when combined with other immunosuppressive therapy, should be used with extreme caution in older adult patients with IBD. � 2017.

Publication Split-dose vs same-day reduced-volume polyethylene glycol electrolyte lavage solution for morning colonoscopy(WJG Press, 2014) ;Chan W.-K. ;Azmi N. ;Mahadeva S. ;Goh K.-L. ;Faculty of Medicine and Health Sciences ;University of Malaya (UM)Universiti Sains Islam Malaysia (USIM)AIM: To compare same-day whole-dose vs split-dose of 2-litre polyethylene glycol electrolyte lavage solution (PEG-ELS) plus bisacodyl for colon cleansing for morning colonoscopy. METHODS: Consecutive adult patients undergoing morning colonoscopy were allocated into two groups i.e., same-day whole-dose or split-dose of 2-litre PEGELS. Investigators and endoscopists were blinded to the allocation. All patients completed a questionnaire that was designed by Aronchick and colleagues to assess the tolerability of the bowel preparation regime used. In addition, patients answered an ordinal fivevalue Likert scale question on comfort level during bowel preparation. Endoscopists graded the quality of bowel preparation using the Boston bowel preparation scale (BBPS). In addition, endoscopists gave an overall grading of the quality of bowel preparation. Cecal intubation time, withdrawal time, total colonoscopy time, adenoma detection rate and number of adenomas detected for each patient were recorded. Sample size was calculated using an online calculator for binary outcome non-inferiority trial. Analyses was based upon intent-to-treat. Significance was assumed at P-value < 0.05. RESULTS: Data for 295 patients were analysed. Mean age was 62.0 � 14.4 years old and consisted of 50.2 % male. There were 143 and 152 patients in the split-dose and whole-dose group, respectively. Splitdose was as good as whole-dose for quality of bowel preparation. The total BBPS score was as good in the split-dose group compared to the whole-dose group [6 (6-8) vs 6 (6-7), P = 0.038]. There was no difference in cecal intubation rate, cecal intubation time, withdrawal time, total colonoscopy time and adenoma detection rate. Median number of adenoma detected was marginally higher in the split-dose group [2 (1-3) vs 1 (1-2), P = 0.010]. Patients in the whole-dose group had more nausea (37.5% vs 25.2%, P = 0.023) and vomiting (16.4% vs 8.4%, P = 0.037), and were less likely to complete the bowel preparation (94.1% vs 99.3%, P = 0.020). Patients in the split-dose group were less likely to refuse the same bowel preparation regime (6.3% vs 13.8%, P = 0.033) and less likely to want to try another bowel preparation regime (53.8% vs 78.9%, P < 0.001). CONCLUSION: Splitting reduced-volume PEG-ELS for morning colonoscopy is as effective as taking the whole dose on the same morning but is better tolerated and preferred by patients. � 2014 Baishideng Publishing Group Inc.
