Twelve HundredConsecutive Pancreato-Duodenectomies from Single Centre: Impact of Centre of Excellence on Pancreatic Cancer Surgery Across India.

Abstract

Pancreato-duodenectomy (PD) is a technically challenging operation with significant morbidity and mortality. Over the period of time, Tata Memorial Centre has evolved into a high-volume centre for management of pancreatic cancer. Aim of this study is to report the short- and long-term outcomes of 1200 consecutive PDs performed at single tertiary cancer centre in India. 1200 PDs were performed from 1992 to 2017. Prospectively maintained database was used to retrospectively assess the short- and long-term outcomes. Study cohort was divided into periods A and B (500 and 700 patients, respectively). Both groups were comparable for demographic variables. Overall morbidity and mortality in entire cohort were 31.2% and 3.9%, respectively. Period B documented significant reduction in post-operative mortality (5.4% vs 2.8%), post-pancreatectomy haemorrhage (5.8% vs 3%) and bile leaks (3.4% vs 1.3%). However, incidence of delayed gastric emptying and clinically relevant post-operative pancreatic fistula was higher in period B. With median follow-up of 25months, 3-year overall survival and disease-free survival for patients with pancreatic cancer were 43.7% and 38.7%, respectively, and that for periampullary tumours were 65.9% and 59.4%, respectively. Period B also corresponded with dissemination of technical expertise across diverse regions of India with specialised training of 35 surgeons. Our study demonstrates the feasibility of delivering high-quality care in a dedicated high-volume centre even in a country with low incidence of pancreatic cancer with marked disparities in medical care and socio-economic conditions. Improved outcomes underscore the need to promote regionalisation via a dedicated training programme.
