My Consultant practice till date has encompassed General and colorectal surgical oncology.

I am Currently Head of Colo-rectal services for the state of Karnataka. I also head the Robotic services for colorectal surgery.

As a part of my higher surgical training, I undertook generic, specialist and sub-specialty training in Colo-rectal, pelvic and peritoneal oncology. St. Marks, the Royal Marsden and the Christie were centers of specialist tertiary colo-rectal practice. Following completion of general surgical and trauma training, I have embarked on advanced colo-rectal training involving minimally invasive, exenterational and cyto-reductive surgery.  I have spent time at St. Marks hospital gaining skill and exposure in MAS (Laparoscopy, SILS & TAMIS), advanced proctology, Pelvic floor,  Intestinal failure, IBD, Polyposis, re-do surgery, recurrent rectal cancers and exenterational surgery. A short fellowship in MAS (Laparoscopy, Robotics) & Exenterational surgery at the Royal Marsden was undertaken. This was followed by a further fellowship in Colorectal, Peritoneal, and Pelvic Oncology with emphasis on Cyto-reductive surgery & HIPEC at the Christie in Manchester, where there was exposure to MIS (Laparoscopy & Robotics).  I was appointed as a laparoscopic colorectal surgeon at Princess Alexandra hospital in Essex in Spring 2017.Further knowledge, skill and experience augmentation has been done from oncology fellowships undertaken at the Memorial Sloan-Kettering Cancer Center in New-York and Champalimaud Foundation in Lisbon, Portugal.

I am building my experience and expertise on minimally invasive (Laparoscopy / SILS / Robotics) surgery. In addition to the generic benign and malignant colorectal work, I provide service around advanced pelvic onco-surgery and peritoneal surface malignancies (Cyto-reductive surgery + HIPEC).

My placements in district hospitals, Trauma centers and Tertiary referral centers have exposed me to a broad generality of Trauma, general and colorectal surgery (open and laparoscopic). I am a JAG accredited upper and lower GI endoscopist and Trainer. Placements post CCT fellowships exposed me to a broad spectrum of tertiary referral practice in colorectal / anal cancers, laparoscopy, pelvic exenterational surgery, Cytoreductive surgery, Robotics and advanced pelvic surgery. In addition knowledge and skills relevant to advanced proctology, IBD, Polyposis, Intestinal failure, pelvic floor and complex colorectal cases were gained. I undertake Ano-rectal physiology and am training at EAUS skills.

Health outcomes research and patient orientated qualitative research are of great interest to me. Management of low rectal cancers, recurrent cancers and peritoneal carcinomatosis are challenging. I would like to weave together my research expertise, clinical acumen and judgement in the decision making process, integrating patient choices into the decision making process of this complex clinical entity. I started my consultant practice on a broad base with both general and colorectal work.  Emergency, endoscopy, proctology, general surgery benign and laparoscopic colorectal resections are what I have undertaken in my initial years of my practice. I am now building on my experience with low rectal cancers, recurrent cancers, exenterational surgery and peritoneal malignancies. Being a keen academic with an interest in research, training and teaching, I am nurturing ties with other sub-specialty centers for building on complex work, research, teaching and training.

His areas of interest are in Cancer surgery (colonic / rectal/ anal / appendiceal / pelvic and peritoneal). His work also includes proctology, inflammatory bowel disease, Diverticulosis and all aspects of functional and pelvic floor problems. He is a Laparoscopic and robotic surgeon.

Books:  Decision making in Surgery and Cancer care


Editor: srossi; ISBN-13: 978-3-659-83834-7 ; (ISBN-10: 3659838349); (EAN: 9783659838347), Published on: 2016-07-26

Blurb/Short text: “The decision-making process represents a more complex cognitive exercise than the actual delivery of a health care intervention.” – Srinivasaiah. This book explores the complex cognitive process and psychology of decision making in surgery and cancer care. Decision-making is a vital part of surgical practice and yet there is a paucity of readily available high quality surgical sciences research. This book presents the methodological details and summarises this area on a global platform. Decision-making is multi-factorial: clinical research evidence, health outcome measures (quality of life, health-related quality of life), clinician factors (knowledge, skill, expertise, judgment), patient factors (socio-economic, education, cultural), nursing factors, translational research, and resource infrastructure, all play a role. Modern health care is moving towards a patient centred care approach and evidence based patient choice and decision making clearly has a greater role to play. Decision-making is at the heart of this process and this book provides a comprehensive introduction and global overview of this essential area of clinical practice.
