INTRODUCTION: Perioperative outcome of Whipple surgery has greatly improved. Quality of life has become an important issue in long-term survivors. Delayed gastric emptying and bile reflux are common concerns. Modified retrocolic posterior gastric gastrojejunostomy with mesocolic stich has been unit's standard practice. Study was designed to assess macro and microscopic bile reflux and dyspepsia related quality of life in long-term survivors. MATERIAL AND METHODS: Out of 42 patients operated from June 2012, twenty long-term survivors were selected after excluding once with recurrence and ones who had chemotherapy during last six months. All underwent gastroscopy. Macroscopic bile reflux was grouped in to four categories. Six gastric biopsies were taken from standard sites. Microscopic bile reflux index (BRI) was calculated in stained specimens. BRI score of 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 48.5 years (21- 69). Median survival of the group was 37 months (6-40). Endoscopically, 18/20 (90%) had macroscopic bile reflux (83.3% yellowish bile lake, 16.7% greenish bile lakes). None had stomal ulcers or macroscopic inflammation. Mean Bile reflux index score was 13.22 (SD: 9.46). Mean dyspepsia score of Whipple group was 23.1 (SD 8.88). In controls, mean dyspepsia score was 20 (SD 8.2), showing no significant difference (p =0.245). CONCLUSION: Though there was macroscopic bile reflux, clinical symptoms and microscopic changes were minimal. Modified technique had good long-term results.
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.
Design and development of a web based histopathology reporting system
(Sri Lanka Medical Association, 2017) Ediriweera, D.S.; Hettiarachchi, W.G.; Mahendra, B.A.G.G.; Liyanage, S.K.; Ratnayake, R.M.U.S.; Hewavisenthi, S.J.de.S.
INTRODUCTION & OBJECTIVES: The current histopathology reporting system in the unit has only basic features including report generation and limited data retrieval. Thus a newer system was required to address the issues faced in histopathology reporting, chiefly 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 study was to design and develop a generic histopathology reporting system that facilitates the generation of timely reports and helps in research and postgraduate training. METHODS: A software framework was designed and developed into a functional web based histopathology reporting system (WBHPRS) which can be easily customizable to different settings. This was designed using MySQL and PHP. Data entry was facilitated by using drop down menus and prompts. Standard templates for reports with the option to edit were uploaded enabling quick report generation. RESULTS: A WBHPRS has the ability to capture data throughout the process of generating a report, thus enabling the tracking of the specimen from surgery to dispatch of the report. The system also provides facilities for more efficient data retrieval due to a modified coding system. It facilitates postgraduate supervision enabling the trainer to determine the time taken, quality and quantity of work done by the trainees. CONCLUSION: This system has vastly enhanced features that will improve the timeliness of reporting and provide additional features useful in research and postgraduate training.
