Introduction: H. pylori eradication reduces the risk of gastric malignancies and peptic ulcer disease. First-line therapies include 14-day PAC (proton pump inhibitor [PPI], amoxicillin, clarithromycin) and PBMT (PPI, bismuth, metronidazole, tetracycline). Second-line therapies include 14-day PBMT and PAL (PPI, amoxicillin, levofloxacin). This clinical audit examined current treatment outcomes in Singapore.Methods: Clinical data of H. pylori-positive patientswho underwent empirical first- and second-line eradication therapies from 1 January 2017 to 31 December 2018 were reviewed. Treatment success was determined by 13C urea breath test performed at least 4 weeks after treatment and 2 weeks off PPI.Results: A total of 963 patients (862 PAC, 36 PMC [PPI, metronidazole, clarithromycin], 18 PBMT, 13 PBAC [PAC with bismuth], 34 others) and 98 patients (62 PMBT, 15 PAL, 21 others) received first-and second-line therapies respectively. A 14-day treatment duration was appropriately prescribed for first- and second-line therapies in 65.2% and 82.7% of patients, respectively. First-line treatment success rates were noted for PAC (seven-day: 76.9%, ten-day: 88.3%, 14-day: 92.0%), PMC (seven-day: 0, ten-day: 75.0%, 14-day: 69.8%), PBMT (ten-day: 100%, 14-day: 87.5%) and PBAC (14-day: 100%). 14-day treatment was superior to seven-day treatment (90.8% vs. 71.4%; P = 0.028). PAC was superior to PMC (P < 0.001) but similar to PBMT (P = 0.518) and PBAC (P = 0.288) in 14-day therapies. 14-day second-line PAL and PBMT had similar efficacy (90.9% vs. 82.4%; P = 0.674).Conclusion: First-line empirical treatment using PAC, PBMT and PBAC for 14 days had similar efficacy. Success rates for second-line PBMT and PAL were similar. [ABSTRACT FROM AUTHOR]

Introduction: Endoscopic submucosal dissection (ESD) provides a higher en bloc and R0 resection rate than endoscopic mucosal resection. Colorectal ESD is not widely used because of its technical difficulty and risk of complications, especially for right-sided colonic lesions. We audited the clinical outcomes of our initial experience with colorectal ESD.Methods: We reviewed data collected from a prospective registry of patients who underwent colorectal ESD from December 2014 to March 2018. Therapeutic outcomes and procedure-related complications were analysed.Results: A total of 41 patients (mean age 67.4 years, 21 male) underwent colorectal ESD. The distribution of the lesions was as follows: rectum (n = 9), sigmoid colon (n = 8), descending colon (n = 6), splenic flexure (n = 1), transverse colon (n = 5), ascending colon (n = 8) and caecum (n = 4). The mean size was 23 (range 12-50) mm. En bloc resection was achieved in 35 (85.4%) out of 41 patients, and R0 resection or clear resection margins was achieved in 33 (94.3%) of the en bloc resection patients. The lesion was upstaged in 14 (34.1%) patients after ESD. Colonic perforation occurred in 3 (7.3%) patients during ESD and was successfully treated with endoscopic clips. There was no procedure-related bleeding. No patient required surgery for management of complications. The median duration of hospitalisation was 1 (range 0-7) day. Four patients with lesions that were upstaged after ESD, from high-grade dysplasia to intramucosal carcinoma with deep submucosal invasion, were referred for colectomy.Conclusion: Our early outcome data was comparable to that from large published series. ESD is an effective and feasible treatment for colorectal lesions. [ABSTRACT FROM AUTHOR]

The landscape of ulcerative colitis has changed in the last two decades. Advancements in pharmacotherapeutics have heralded the introduction of new treatment options, with many agents in development. Better clinical outcomes are seen with tighter disease control, made possible with greater understanding of inflammatory pathways and their blockade with drugs. There has been a resultant shift in treatment targets, beyond symptoms to endoscopic and histological healing. Controlling the burden of disease activity also lowers the risk of developing colorectal cancer. Colorectal cancer screening now requires the use of dye-based agents and high-definition colonoscopy to improve the detection of colonic neoplasms., (Copyright © 2024 Copyright: © 2024 Singapore Medical Journal.)
