Clinicopathologic characteristics and treatment outcomes of pancreatic cancer patients at a tertiary referral hospital in Kenya.

The global incidence of pancreatic cancer (PC) continues to steadily increase whereas its prognosis remains poor. Previous studies have suggested worse outcomes among individuals of African descent. The characteristics of patients with PC in Kenya, and their contemporary management and survival outcomes remain largely unknown. This study aimed to describe the clinical and pathologic characteristics, management, and outcomes of patients diagnosed with PC at Kenyatta National Hospital (KNH), a tertiary referral hospital in Kenya. Records of 242 patients diagnosed with PC at KNH between 1st January 2014 and 30th September 2021 were assessed in this retrospective cohort study. Data on their clinical, histopathologic, and treatment characteristics was presented as mean (± standard deviation) and/or median (interquartile range) for continuous variables and frequency (percentage) for categorical variables. Kaplan-Meier and Cox proportional hazard ratios were used for survival analysis. PC occurred in a young population, the median age being 58.5 years (inter-quartile range 35-88). The majority of tumours (54%) were metastatic at diagnosis, while 28% and 14% were stage III and stage I/II, respectively. Surgical resections with curative intent were performed on 7% overall and 44% of stage I/II cases. The majority of patients with stage I/II disease (52.9%) received chemotherapy whereas the majority with stage III and IV disease received the best supportive care only (62.7% and 64.9%, respectively). Patients who underwent surgical resection (HR for mortality 0.20, 95% CI 0.05-0.83, p = 0.021) and chemotherapy (HR for mortality 0.15, 95% CI 0.08-0.29, p < 0.001) had significantly improved survival, reflecting a more favourable stage of the disease more amenable to aggressive therapies. The median survival time was 3 months and the 1-year survival rate was 32%.

Assessment of endoscope reprocessing at World Gastroenterology Organisation training centers using adenosine triphosphate testing.

Background and study aims Adequacy of endoscope disinfection in resource-limited settings is unknown. Adenosine triphosphate (ATP) testing is useful for evaluation of endoscope reprocessing, and ATP <200 relative light units (RLUs) after manual endoscope cleaning has been associated with adequacy of endoscope disinfection. Methods Consecutive endoscopes undergoing reprocessing at five World Gastroenterology Organisation (WGO) training centers underwent ATP testing before and after an on-site educational intervention designed to optimize reprocessing practices. Results A total of 343 reprocessing cycles of 65 endoscopes were studied. Mean endoscope age was 5.3 years (range 1-13 years). Educational interventions, based on direct observation of endoscope reprocessing practices at each site, included refinements in pre-cleaning, manual cleaning, high-level disinfection, and endoscope drying and storage. The percentage of reprocessing cycles with post-manual cleaning ATP ≧200 decreased from 21.4% prior to educational intervention to 14.8% post-intervention ( P =0.11). In multivariable logistic modelling, gastroscopes were significantly less likely (odds ratio [OR] 0.04, 95% confidence interval [CI] 0.01-0.19; P <0.001) than colonoscopes to achieve post-manual cleaning ATP < 200. No other factor (educational intervention, study site, endoscope age) was significantly associated with improved outcomes. Endoscope ID was not significantly associated with ATP values, and sites that performed manual versus automated HLD did not have significantly different likelihood of post-manual cleaning ATP <200 (OR 1.18, 95% CI 0.56-2.50; P =0.67). Conclusions In resource-limited settings, approximately 20% of endoscope reprocessing cycles may result in inadequate disinfection. This was not significantly improved by a comprehensive educational intervention. Alternative approaches to endoscope reprocessing are needed.

Gastrointestinal endoscopy capacity in Eastern Africa.

Background and study aims Limited evidence suggests that endoscopy capacity in sub-Saharan Africa is insufficient to meet the levels of gastrointestinal disease. We aimed to quantify the human and material resources for endoscopy services in eastern African countries, and to identify barriers to expanding endoscopy capacity. Patients and methods In partnership with national professional societies, digestive healthcare professionals in participating countries were invited to complete an online survey between August 2018 and August 2020. Results Of 344 digestive healthcare professionals in Ethiopia, Kenya, Malawi, and Zambia, 87 (25.3 %) completed the survey, reporting data for 91 healthcare facilities and identifying 20 additional facilities. Most respondents (73.6 %) perform endoscopy and 59.8 % perform at least one therapeutic modality. Facilities have a median of two functioning gastroscopes and one functioning colonoscope each. Overall endoscopy capacity, adjusted for non-response and additional facilities, includes 0.12 endoscopists, 0.12 gastroscopes, and 0.09 colonoscopes per 100,000 population in the participating countries. Adjusted maximum upper gastrointestinal and lower gastrointestinal endoscopic capacity were 106 and 45 procedures per 100,000 persons per year, respectively. These values are 1 % to 10 % of those reported from resource-rich countries. Most respondents identified a lack of endoscopic equipment, lack of trained endoscopists and costs as barriers to provision of endoscopy services. Conclusions Endoscopy capacity is severely limited in eastern sub-Saharan Africa, despite a high burden of gastrointestinal disease. Expanding capacity requires investment in additional human and material resources, and technological innovations that improve the cost and sustainability of endoscopic services.
