Item Implementation of an Online Histopathology Reporting System in the Department of Pathology, Faculty of Medicine, University of Kelaniya(19th Conference on Postgraduate Research, International Postgraduate Research Conference 2018, Faculty of Graduate Studies,University of Kelaniya, Sri Lanka, 2018) Hettiarachchi, W.G.; Ediriweera, E.P.D.S.; Mahendra, B.A.G.G.; Liyanage, S.K.; Hewavinsenthi, S.J.D.S.; Ratnayake, R.M.U.S.The Department of Pathology, Faculty of Medicine, University of Kelaniya provides histopathology reporting for the Colombo North Teaching Hospital (NCTH) as an honorable service. The department currently uses a standalone Microsoft access database to generate reports and it has limited data retrieval capabilities. A newer system was required to address the issues faced, mainly a prolonged turnaround time caused by lack of clinical data, inability to track delays in sample processing, delays in data entry and report dispatch. More efficient data retrieval for research purposes and monitoring of postgraduate training were also considered important. The aim of the work was to implement anonline histopathology reporting system that has facility to track the reporting stage, postgraduate evaluation and data retrieval for researches. Every report is attached with a diagnostic code that can be used in research purposes. A web-based application was developed that has ability to capture data at each step from specimen receiving from the surgery theatre until dispatch of reports. The system has developed to easily customizable to different settings. Thus, it has facility to add new reporting templates, anatomical sites, surgical specimens or diagnostic codes to system through web forms. Data entry was facilitated by using drop down menus and prompts. Standard templates for reports with option to edit were uploaded enabling quick report generation. It facilitates postgraduate supervision by enabling the trainer to determine the time taken, quality and quantity of work done by the trainees. Mainly open source scripting languages and databases were used to developed the system: PHP, HTML 5, CSS Javascript, Ajax and MySQL. The system hosted on the faculty intranet and available 24/7 from anywhere at the faculty. The system supports both windows and androids operating systems and the system can be accessed in desktop and tablet computers using any commonly used modern web browsers.Item An audit of lymph node retrieval and histopathology reporting of pancreaticoduodenctomy specimens undertaken at a tertiary care referral center(College of Pathologists of Sri Lanka, 2017) Siriwikum, L.B.D.J.; Samarakoon, N.K.; Liyanage, S.K.; Mahendra, B.A.G.G.; Ratnayake, R.M.U.S.; Hewavisenthi, S.J.de S.Pancreaticoduodenectomy (PD) is currently the main surgical option for malignancies in the ampullary region, which includes ampulla of Vater tumours (AVT), distal bile duct tumours (DBDT), periampullary duodenal tumours (DT) and tumours of the head of the pancreas (PT). Nodal status and many other important pathological features have a significant impact on tumour prognosis and therapy. The aim of this study was to determine the total number of lymph nodes (LNs) retrieved from PD specimens, whether grouping of LNs improves the total yield and to assess the level completeness of histopathology reporting of PD specimens. Forty two PD requests and histopathology reports were assessed to determine the total number of LNs retrieved and whether the LN were grouped (G)or non-grouped (NG). The significance of difference in the number of LNs in the two groups were assessed using the Wilcoxon signed rank test. The tumours were subcategorized as AVT, DBDT, DT and PT and the reports were audited against the respective minimum data sets of the Royal College of Pathologists of United Kingdom to determine the overall completeness and the parameters poorly reported in the reports. The overall median LN yield was 14.5 and the median LN yield was 15 and 10 in G and NG respectively which was statistically significant. The completeness of the histopathology reporting was 63.6%- 77.3% in AVT (n-18), 73.9% - 95.6% in DBDT (n-5), 68.1% - 90.1% in DT (n-8), 70.8% - 83.3% in PT (n-11). The lengths of the bile duct, lesser and greater curvature of the stomach, tumour differentiation, involvement of resection margins and named blood vessels were poorly reported. In conclusion, the total LN retrieval improved by grouping according to the Union of International Cancer Control (UICC) protocol. Histopathology reporting of some of the data items requires improvement. Hence adoption of a pro forma for synoptic reporting and establishment of national guidelines on reporting and handling of specimens is recommended.Item Quality of life and impact of bile reflux after retro colic retro gastric gastrojejunostomy in Whipple surgery(Biomed Central, 2017) Siriwardana, R.C.; Lokubandara, R.W.M.A.; Hewavisenthi, S.J.de S.; Liyanage, S.K.; Jayatunga, D.S.P.; Liyanage, C.A.H.Background: Delayed gastric emptying and bile reflux are common concerns in long-term survivors after Whipple surgery. The study was designed to assess modified retro colic retro gastric gastrojejunostomy in reducing macro and microscopic bile reflux and impact on dyspepsia related quality of life in long-term survivors. Methods: Out of 43 patients operated, 23 long-term survivors were included. All underwent gastroscopy and bile reflux was grouped as normal, yellowish bile lakes and presence of greenish bile lakes. Six standard gastric biopsies were taken. Microscopic bile reflux index (BRI) was calculated and a score more than 14 was considered significant. Validated Nepean dyspepsia index-short form (NDI-SF) was used to assess the severity of dyspepsia-related quality of life and compared with age and gender-matched control. Results: The median age was 48 (21–70) years. Median survival of the group was 37 months (6–40). Endoscopically, 20/23 (87%) had macroscopic bile reflux (74% yellowish bile lakes, 13% greenish bile lakes). None had stomal ulcers or macroscopic inflammation. Mean bile reflux index score was 9.7 (range 1.77–34). Mean NDI–SF score of Whipple group was 23.1 (SD 8.88). In controls, mean score was 19.9 (SD 8.23), showing no significant difference (p = 0.245). Conclusions: Though there was macroscopic bile reflux, clinical symptoms and microscopic changes were minimal. The modified technique had good long-term results.
