    (5th International Conference for Accounting Researchers and Educators (ICARE – 2019), Department of Accountancy, Faculty of Commerce & Management Studies, University of Kelaniya, Sri Lanka, 2019) Wijesinghe, N.; Bandara, S.; Dassanayake, W.; Undugoda, M.
    Good corporate governance is directly linked with the shareholder wealth creation and thereby positively impacting on the overall economic prosperity of entities. However, achieving the ideal outcomes from good corporate governance is vulnerable to a multitude of hindrances originating from the internal and external forces. The purpose of this study is to examine how corporate governance practices impact on the firm value. Data collected through content analysis of annual reports of 27 Sri Lankan manufacturing firms listed in the Colombo Stock Exchange from 2012 to 2016. The study used descriptive statistics and multiple regression analysis to analyze data. Findings revealed that the number of board meetings and internal control and risk management system of listed manufacturing companies capable of improving firm value. The study has social and policy impact as it highlights the importance of corporate governance practices in Sri Lankan entities. Focusing on one industry sector is an inherent limitation of the study, and industry sector comparison would be a potential future research area.

    Usefulness of routine terminal ileoscopy and biopsy during colonoscopy in a tropical setting: a retrospective record-based study
    (Hindawi Publishing Corporation, 2014) Wijewantha, H.S.; de Silva, A.P.; Niriella, M.A.; Wijesinghe, N.; Waraketiya, P.; Kumarasena, R.S.; Dassanayake, A.S.; Hewavisenthi, S.J.de S.; de Silva, H.J.
    Introduction. Available evidence for routine terminal ileoscopy during colonoscopy is equivocal. We investigated the place of routine terminal ileoscopy and biopsy during colonoscopy, in a tropical setting. Materials and Methods. All consenting adults undergoing colonoscopy had routine TI and biopsy. Patients with right iliac fossa (RIF) pain, diarrhoea, anaemia, suspected inflammatory bowel disease (IBD), and raised inflammatory markers were defined as Group A and all others undergoing colonoscopy as Group B. Results. Caecal intubation and TI were achieved in 988/1096 (90.15%) and 832/1096 (75.9%) cases, respectively. 764/832(91.8%) patients were included in final analysis. 81/764 (10.6%) patients had either macroscopic (34/81) or microscopic (47/81) abnormalities of terminal ileum; 20/81 had both. These were CD (28/47), tuberculosis (TB) (6/47), ileitis due to resolving infection (8/47), and drug-induced ileitis (5/47). 27/81 with macroscopically normal ileum had CD (18/27), ileitis due to resolving infection (5/27) and drug-induced ileitis (4/27) on histology. 12/764 (1.57%) patients with macroscopically normal colon had ileal CD (8/12), drug-induced ileitis (2/12), and resolving ileal infection (2/12) on histology. 47/764 (6.15%) patients had ileal pathology that influenced subsequent management. These were significantly higher in Group A (43/555 (8%)) than in Group B (4/209 (1.9%)) (P = 0.0048, χ (2) = 7.968). Conclusion. TI and biopsy improve diagnostic yield of colonoscopy in patients with RIF pain, diarrhoea, anaemia, suspected IBD, and raised inflammatory markers.
