Item Bile reflux and quality of life after modified retrocolic posterior gastric gastrojejunostomy in whipple procedure(College of Surgeons of Sri Lanka, 2015) Rajapaksha, R.W.M.A.L.; Liyanage, C.A.H.; Hewavisenthi, S.J.D.S.; Liyanage, S.K.; Bandara, L.M.P.M.; Siriwardana, R.C.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.Item 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.Item A Retrospective study on perinatal post-mortems(University of Kelaniya, Sri Lanka, 2016) Liyanage, S.K.; Mahendra, B.A.G.G.; Ratnayake, R.M.U.S.; Hewavisenthi, S.J.A post-mortem examination is the key to the recognition of pathologies related to perinatal deaths. A perinatal death could be related to fetal, maternal or placental factors. A complete perinatal post-mortem (PPM) includes examination of the dead body and the placenta. The PPM findings assist the clinical team in confirming their clinical findings and uncover the additional pathologies, and the family for future pregnancy planning. This study was carried out to identify the number of perinatal post mortems (PPMs) reported during the study period, the number of PPMs with multiple congenital anomalies and the number of PPMs accompanied by a placenta and the number of placentae with identifiable pathology. This study was on already reported PPMs in a tertiary care center from January 2011- August 2016. Multiple congenital anomalies were noted in 14% (16/118) of the PPMs. Placentae were submitted for examination in 26% (31/118) with clinically significant placental pathologies in 23% (7/31). In 64% (76/118) of PPMs there were no gross abnormality in the fetus/baby. The placenta was not available for examination in 72% (55/76) and therefore, the possibility of placental pathology, which might have led to the death, could not be excluded.
