Some of my papers are available full-text at the following links

These are in reverse chronological order rather in order of importance.

1. Dr Starzl's obituary. Dr Starzl was a pioneer of solid organ transplantation. He performed the first successful liver transplant in 1967. He developed the field of liver transplantation to its present level of safety. I did my fellowship at the Thomas Starzl Transplantation Institute. When he passed away, the editors of the National Medical Journal of India asked me to write his obituary. http://www.nmji.in/article.asp?issn=0970-258X;year=2017;volume=30;issue=2;spage=108;epage=109;aulast=Kumaran
2. A recto-vaginal fistula a complication of abadly managed obstructed delivery or sometimes after other operations in the pelvis. A difficult condition to treat, it has a high recurrence rate. We managed several patients with this condition at Sir Ganga Ram Hospital. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4775704/
3. Impaired blood supply to the intestine can lead to gangrene and the need to remove most of the bowel and possibly requiring a bowel transplant. https://www.ncbi.nlm.nih.gov/pubmed/27011468

4. The schedule for following up patients after surgery for cancers of the gastrointestinal tract is not really standardised. The pattern of disease and the patterns and timing of recurrence are different for the diseases more common in India. We developed standard guidelines for follow up of Indian patients. https://www.ncbi.nlm.nih.gov/pubmed/26396472

5. The Indian Association for Study of the Liver held a consensus conference in 2013 to develop Indian guidelines for prevention, surveillance, diagnosis and treatment of liver cancer. I wrote the guidelines for liver transplantation for liver cancer. https://www.ncbi.nlm.nih.gov/pubmed/25755618

6. Some patients with liver disease also have thrombosis (clotting) of the portal vein and its tributaries. Traditionally such patients could not have a liver transplant. We described an innovative technique to successfuly transplant a patient with this condition. The patient is still alive and well 5 years after the transplant. https://www.ncbi.nlm.nih.gov/pubmed/25267282

7. While working on ways to make hepatocyte transplantation (transplantation of liver cells) work in the lab in animals, we found that Etanercept, which reduce inflammation by blocking the action of TNF-alpha can improve the engraftment od transplanted hepatocytes. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4176524/

8. Indication and contraindications for liver transplantation, a review article. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3189562/
