(The Sri Lanka Medical Association, 2023) Fernando, M.; Tillakaratne, S.; Gunetilleke, B.; Liyanage, C.; Appuhamy, C.; Weerasuriya, A.; Dissanayake, J.; Siriwardana, R.
Liver transplant (LT) is the standard therapy for medically refractory acute liver failure (ALF). Finding a deceaseddonor graft in an emergency is challenging and often overcome by living-donation. Blood group matching is practised for LT though ABO-incompatible liver transplant (ABOi-LT) is performed inselected circumstances. We report an infant who underwent successful ABOincompatible living donor LT for ALF of unknown aetiology. This being the country’s first ABOi-LT, the youngest LT recipient to date and the youngest receiving emergency LT for ALF; we describe the novel experience at a resource-limited setting in Sri Lanka (SL).

(Wiley, 2024) Fernando, M.; Tillakaratne, S.; Gunetilleke, B.; Liyanage, C.; Appuhamy, C.; Weerasuriya, A.; Uragoda, B.; Welikala, N.; Ranaweera, L.; Ganewatte, E.; Dissanayake, J.; Mudalige, A.; Siriwardana, R.
ABSTRACT: BACKGROUND: Liver transplant is the cure for children with liver failure. Sri Lanka is a lower-middle-income country with a predominant free, state health system. Pediatric liver transplant program in Sri Lanka is still in the budding state where the initial experience of the program is yet to be documented. METHODS: A retrospective review was performed including the clinical characteristics of all pediatric liver transplant recipients of Colombo North Centre for Liver Diseases since the inception of the program from June 2020 to May 2023. RESULTS: There were 14 PLT performed in 3 years. The median recipient age and weight were 8 years (6 months–15 years) and 23.3 kg (6.4–49.2), respectively. The majority were boys (64%). All were from low-income backgrounds. Indications for LT were acute liver failure (5/14), decompensated chronic liver disease (5/14), and acute on chronic liver failure (4/14). Underlying liver diseases were Wilson disease (6/14), autoimmune liver disease (3/14), biliary atresia (2/14) and progressive familial intrahepatic cholestasis type 3 (1/14), and unknown etiology (2/14). The majority were living donor liver transplants (86%). Of the living donors, 42% (5/12) were Buddhist priests. There were three immediate deaths and two late deaths. The 3-month survival was 78%, and overall survival was 64%. Living donor transplants carried a higher success rate (92%) compared to diseased donor transplants (0%; 2/2). CONCLUSIONS: Initial experience of pediatric liver transplant program of Sri Lanka is promising despite being established in a free healthcare system amidst the crisis circumstances.

Fifty liver transplants: a single centre experience of haemodynamic management in liver transplantation for cirrhosis [part 1]
(College of Surgeons of Sri Lanka, 2021) Gunetilleke, B.; Ranamuni, R.; Jayaweera, D.; Welikala, N.; Kerner, V.; Munasinghe, N.; Withanage, R.; Wickremasinghe, N.; Hewage, S.; Wijesuriya, N.; Rodrigo, U.; Mudalige, A.; Fernando, M.; Hettiarachchi, D.; Dissanayake, J.; Niriella, M.; Dassanayake, A.; Thilakaratne, S.; de Silva, J.; Siriwardana, R.; WIjesuriya, R.; Liyanage, C.
ABSTRACT: Cirrhosis with end stage liver disease (ESLD) is a leading cause of non-communicable disease related deaths in Sri Lanka. Liver transplantation is the only curative treatment for patients with ESLD. The complex multisystem involvement and unique cardiovascular profile characteristic of ESLD present formidable challenges during liver transplantation. Management of the rapid and varied hemodynamic changes during surgery requires an in depth understanding of the physiological effects of each intervention. Based on the current literature and the experience gained at our center during the management of 50 liver transplants, we present optimization strategies and perioperative hemodynamic interventions which we use to ‘Fast track’ recovery following liver transplantation.

Fifty liver transplants: a single centre experience of haemodynamic management in liver transplantation for cirrhosis [part 2]
(The College of Surgeons of Sri Lanka, 2021) Gunetilleke, B.; Ranamuni, R.; Jayaweera, D.; Welikala, N.; Kerner, V.; Hettiarachchi, D.; Munasinghe, N.; Withanage, R.; Wickremasinghe, N.; Hewage, S.; Fernando, M.; Hettiarachchi, D.; Niriella, M.; Dassanayake, A.; Thilakaratne, S.; Wijesuriya, R.; Liyanage, C.; Siriwardana, R.; Dissanayake, J.; Wijesuriya, N.; Rodrigo, U.; Rodrigo, U.; Mudalige, A.; de Silva, J.
Globally, an estimated one million deaths occur annually due to complications of cirrhosis. Cirrhosis with end stage liver disease [ESLD] is a leading cause death due to non- communicable diseases in Sri Lanka. Non-alcoholic fatty liver disease [NAFLD] and alcohol related liver disease [ARLD] are the principal causes of ESLD due to cirrhosis in Sri Lanka. Liver transplantation remains the only curative treatment for such patients. Multiorgan dysfunction and hemodynamic instability characteristic of ESLD adds to the complexity of perioperative care in liver transplantation. Maintenance of stable hemodynamics including optimal hemostasis forms the core of the anaesthetic strategy in liver transplantation.
First paediatric live donor liver transplant in Sri Lanka with 1 year outcome : challenges for the future
(The College of Surgeons of Sri Lanka, 2021) Siriwardana, R.; Thilakarathne, S.; Fernando, M.; Gunetilleke, M.B.; Weerasooriya, A.; Appuhamy, C.
INTRODUCTION: Liver transplantation in the paediatric age group is demanding due to smaller body proportions and physiology. This paper describes the first successful paediatric liver transplant in Sri Lanka along with its one-year outcome. Describing the challenges faced during the process, we highlight the factors that need to be considered for a sustainable programme in the future. METHODOLOGY: A 9-year-old girl who had progressive familial intra hepatic cholestasis type 3 was referred to us with features of end stage liver disease. She was identified as a suitable candidate for liver transplantation. Her 38-year-old mother was selected as the donor, who was evaluated for suitability of a left lateral segment donation. RESULTS: The first paediatric liver transplantation was performed in July 2020. The child's mother donated the left lateral segment weighing 325g. During the postoperative period the child developed outflow tract obstruction at the hepatic venous anastomosis. This was managed with a percutaneously placed stent. Six months after transplant, she developed an acute rejection that required steroids. Treatment of rejection was complicated with multiple liver abscesses caused byAspergillus. The infection was treated with systemic antifungals and drainage. At one-year post transplant, the recipient had recovered from the trauma of surgery and had normal liver biochemistry, a patent hepatic venous stented anastomosis and complete resolution of the abscesses. We faced dual challenges in dealing with a live liver transplant donor and a young child who was the recipient. Our success, on this occasion, was underscored by the multidisciplinary contribution from specialists scattered across the island combined with state-public partnership. CONCLUSION: To offer a sustainable live donor liver transplant service for the future, many other aspects, beyond surgery itself, need to be addressed.
Hepatocellullar carcinoma: the Sri Lankan perspective
(Faculty of Medicine, University of Kelaniya, Sri Lanka, 2016) Siriwardana, R.
Ragama has become a center of excellence in the management of hepatocellular carcinoma (HCC). Since 2012 we have managed approximately 500 patients with HCC referred from different parts of the country. Sri Lanka appears to have an unique pattern of disease not seen in any other part of the world. The large majority of HCC in our population is related to non-alcoholic fatty liver disease (NAFLD). With novel treatment of hepatitis C and hepatitis B vaccination globally, it is predicted that NAFLD will be the leading cause of liver disease in the future. In Sri Lanka with rapidly rising prevalence of NAFLD, liver cancer will also continue to rise. In this background of NAFLD, diffuse variant of HCC has higher incidence in our patients. Consumption of alcohol is a risk factor to develop diffuse type HCC. Diffuse type HCC has a grave prognosis. A significant proportion of NAFLD patients develop HCC in non-cirrhotic liver. This raises the need to screen at-risk groups in the future. These non-cirrhotic hepatomas are larger in size and have a better prognosis than others. Alpha-feto protein is an unreliable marker in the assessment of our patients with NAFLD induced HCC. Our cohort of patients is an excellent sample to study the future pattern of HCC worldwide.

The use of enteral nutrition over parenteral nutrition is recommended in the case of patients undergoing major gastrointestinal surgery for cancer, as it reduces sepsis related morbidity. In this study we compared ourexperience of nasojejunal tube feeding with feeding jejunostomy
Optimizing intraoperative haemodynamics and haemostasis to enhance recovery after liver transplantation for cirrhosis in adults
(College of Anaesthesiologists of Sri Lanka, 2022) Gunetilleke, B.; Welikala, N.; Ranamuni, R.; Jayaweera, D.; de Silva, T.; Amerasinghe, O.; Liyanage, C.; Dissanayake, J.; Appuhamy, C.; Fernando, M.; Thilakarathne, S.; Dassanayake, A.; Niriella, M.; Siriwardana, R.; Gilbert-Kawai, E.
Cirrhosis with end stage liver disease is a leading cause of non-communicable disease related deaths in Sri Lanka. Liver transplantation remains the only curative treatment for such patients. Multi-organ dysfunction characteristic of end stage liver disease, surgical and anaesthetic factors, quality of the graft, coagulopathy and haemodynamic instability, all lead to the complexity of the perioperative care for liver transplant. Aggressive management focused particularly on maintaining intra-operative haemodynamic stability and optimizing haemostasis, directly impacts successful patient outcomes and forms the core of the anaesthetic strategy.

Presence of fatty liver disease leads to unusual rise of liver enzymes in patients with common bile duct colic
(Korean Association of Hepato-Biliary-Pancreatic Surgery, 2021) Uragoda, B.; Ediriweera, D.; Paranahewa, L.; Ekanayake, C.; Tillakarathna, S.; Siriwardana, R.
INTRODUCTION: This study compares liver enzymes, inflammatory markers and bilirubin levels in patients with and without fatty liver disease (FLD) presenting with common bile duct (CBD) obstruction. METHODS: CBD colic was diagnosed based on clinical, radiological and biochemical criterion. Presence of FLD was diagnosed by ultra sound scan and the macroscopic appearance of liver during surgery. Liver enzymes, inflammatory markers and bilirubin levels were prospectively assessed and compared between the two groups. RESULTS: Out of 42, there were 22 (52.3%) patients with FLD. Median body mass index was 26.9 (24.1–30.8) in fatty liver group compared to 25.7 (23.5–26.2) in others. Individuals with FLD showed high aspartate transaminase (558.5 vs. 247.0, p = 0.005), alanine trasaminase (467 vs. 228.5, p = 0.005) and bilirubin (3.8 vs. 2.2, p = 0.015) levels compared to those without FLD. According to multiple linear regression models, high AST and ALT levels showed significant associations with FLD after adjusting for age, gender, body mass index, amylase and C reactive protein levels. The median enzyme level at two weeks did not show a difference among patients with and without FLD. CONCLUSIONS:Presence of FLD causes unusual rise of AST and ALT levels in patients with CBD stones. This rise is transient.

Solid pseudopapillary tumour of the pancreas: an uncommon pancreatic tumour in Sri Lanka
(The college of surgeons of Sri Lanka, 2024) Tillakaratne, S.B.; Cooray, S.; Gunetilleke, B.; Siriwardana, R.
INTRODUCTION AND OBJECTIVES Solid pseudopapillary tumour of the pancreas (PST) is a rare exocrine pancreatic tumour commonly involving the body and the tail of the pancreas. It's seen predominantly in young women. Even patients who present with metastatic disease have good survival after resection. We looked at our experience with this rare tumour. METHODS Prospectively collected proforma-based data were analysed.RESULTS 14 patients underwent surgery for PST from November 2011 to October 2022. 13 (93%) were females. The median age was 28 years (15-50). Nine (64.3%) patients presented with abdominal pain, and 3(21.4%) had an abdominal mass at presentation. Only 2(14.3%) patients were incidentally detected. The median tumour diameter was 7.2cm (218).7(50%) had involvement of the pancreatic body, 6(43%) had involvement of the head of the pancreas, and one had involvement of both the head and the body of the pancreas. Only one patient (7.14%) had liver metastasis at presentation. Distal pancreatectomy was performed in 6(43%), Whipple's pancreaticoduodenectomy in 6(43%), enucleation in 1(7.14%) and total pancreatectomy in 1(7.14%). In addition, liver metastasectomy was done in 1(7.14%) patient. There were no major complications. None received adjuvant treatment. At a median follow-up of 22 months, there were no recurrences. CONCLUSIONS PST in our cohort were in young females who had excellent survival after surgical resection. Involvement of the head of the pancreas was common compared to the predominantly distal disease in the available literature.
