The present study examined 424 Indian chronic pancreatitis research publications, as indexed in Scopus database during 2007-16, with a view to understand their growth rate, global share, citation impact, international collaborative papers share, distribution of publications by broad subjects, productivity and citation profile of top organizations and authors, preferred media of communication and characteristics of high cited papers. The Indian publications registered an annual average growth rate of 8.73%, global share of 5.48%, international collaborative publications share of 13.68% and its citation impact averaged to 11.06 citations per paper. Medicine, among broad subjects, contributed the largest publications share of 92.45% in India’s chronic pancreatitis research output, followed by biochemistry, genetics & molecular biology (27.83%) and pharmacology, toxicology & pharmaceutics (2.83%) during 2007-16. Among various organizations and authors contributing to India’s chronic pancreatitis research, the top 20 organizations and authors together contributed 80.42% and 81.84% respectively as their share of Indian publication output and more than 100% each respectively as their share of Indian citation output during 2007-16. Among 415 journal papers in Indian chronic pancreatitis research, the top 15 journals registered 49.67% share during 2007-16, which showed decrease from 55.56% to 45.84% from 2007-11 and 2012-16. There were only top 9 highly cited publications, which registered citations from 112 to 268 during 2007-16 and they together received 1414 citations, which averaged to 1157.11 citations per paper.

The pancreas is an organ located in the abdomen. It plays an essential role in converting the food we eat into fuel for the body's cells. The pancreas has two main functions: an exocrine function that helps in digestion and an endocrine function that regulates blood sugar [1].
Pancreatitis means inflammation of the pancreas. There are two types: (i) Acute pancreatitis and (ii) Chronic pancreatitis. In acute pancreatitis, the inflammation develops quickly, over a few days or so. It usually goes away completely and leaves no permanent damage to the pancreas. In contrast, in chronic pancreatitis, the inflammation is persistent and ongoing over time and it can cause scarring and damage to parts of the pancreas. This can then lead to not enough chemicals (enzymes) and insulin being made, which causes poor digestion of food and diabetes. Also the clumps of calcium are deposited and can form stones in the pancreas over time. Calcium stones and/or scarring of the pancreatic tubes (ducts) may block the flow of enzymes along the pancreatic ducts [2-3].
The most common cause of chronic pancreatitis is many years of heavy alcohol use. Approximately 70 percent of cases are linked to alcohol consumption. Other causes of chronic pancreatitis are: hereditary disorders of the pancreas, cystic fibrosis—the most common inherited disorder leading to chronic pancreatitis, hypercalcemia high levels of calcium in the blood, hyperlipidemia or hypertriglyceridemia—high levels of blood fats, some medicines, certain autoimmune conditions and unknown causes [3]
Literature Review
So far only two bibliometric studies have published in the area of pancreas research. The first study focuses on Indian pancreas research output comprising of 3858 papers [4] and the second study focuses on Indian acute pancreatitis research output comprising of 581 papers [5]. Both the studies used Scopus database and covered the period 2007-16. In both the studies, emphasis was on studying the growth rate, global share, citation impact, international collaborative papers share, distribution of publications by broad subjects, productivity and citation profile of top organizations and authors, preferred media of communication and characteristics of high cited papers
The present manuscript aims to study the various dimensions of India’s chronic pancreatitis research in terms of various bibliometric indicators, using Scopus international database during 2007-16. In particular, the study analyzed overall annual and cumulative growth of Indian publications, its global share among top 10 most productive countries, its citation impact, its international collaborative papers share, the publication output distribution by broad sub-fields, the productivity and citation impact of most productive organizations and authors, leading media of communications and characteristics of its top highly cited papers.
The Indian chronic pancreatitis publication data during 2007-16 was retrieved and downloaded from the Scopus database for the present study. For deriving publication data, a main search strategy was formulated, where the keyword such as “chrnic pancreatitis’’ is searched in the “keyword tag” or ‘’Article Title Tag’’ or “Source Title tag” and further limited the search output to period ‘2007-16’ within “date range tag”. This search strategy generated 7734 global publications on chronic pancreatitis from the Scopus database. This main search strategy was later refined by ‘’Country Name Tag’’ to get chrnic pancreatitis research output of individual top 10 most productive countries, including India one by one. Detailed analysis was carried out on 424 Indian publications using the analytical provisions or tags existing in Scopus database such as “subject area tag”, “country tag”, “source title tag”, “journal title name” and “affiliation tag”, to get data distribution by subject, collaborating countries, author-wise, organization-wise and journal-wise, etc. For citation data, citations to publications were also collected from date of publication till 3 October 2017. A series of raw and relative bibliometric indicators were used by authors to understand the dynamics of India’s chrnic pancreatitis research from different perspective
(KEY(chronic pancreatitis* or pancreatitis, chronic ) OR TITLE(chronic pancreatitis* or pancreatitis, chronic) OR SRCTITLE(''chronic pancreatitis*'')) AND PUBYEAR > 2006 AND PUBYEAR < 2017 AND ( LIMIT-TO ( AFFILCOUNTRY,"India" ) )
The global and Indian research output in chronic pancreatitis research cumulated to 7734 and 424 publications in 10 years during 2007-16 and they registered from 765 and 27 publications in the year 2007 to 762 and 46 publications in the year 2016, registering 0.33% and 8.73% growth per annum. Their five-year cumulative output increased from 3699 and 166 to 4035 and 258 publications from 2007-11 to 2012-16, registering 9.08% and 55.42% growth respectively. The share of Indian publications in global output was 5.48% during 2007-16, which increased from 4.49% to 6.39% from 2007-11 to 2012-16. Amongst Indian publications on chronic pancreatitis, 68.40% (290) was published as articles, 11.08% (47) as reviews, 10.14% (43) as letters, 4.25% (18) as notes, 2.36% (10) as editorials, 1.42% (6 each) as book chapters and conference papers, 0.47% (2) as articles in press and 0.24% (1 each) as book and short survey. The research impact as measured by citations per paper registered by global and Indian publications in chronic pancreatitis averaged to 16.52 and 11.06 citations per publication (CPP) during 2007-16; five-yearly impact averaged to 23.17 and 18.89 CPP for the period 2007-11 which declined to 10.42 and 6.03 CPP in the succeeding five-year 2012-16 (Table 1).

Subject-Wise Distribution of Indian Research Output
As per the Scopus database classification, India’s chronic pancreatitis research output is distributed across three-fields during 2007-16. Among sub-fields, medicine registered the highest publications share (92.45%), followed by biochemistry, genetics & molecular biology (27.83%) and pharmacology, toxicology & pharmaceutics (2.83%) during 2007-16. The publication activity, as seen through activity index from 2007-11 to 2012-16, witnessed decrease in medicine (from 102.95 to 98.10), biochemistry, genetics & molecular biology (from106.06 to 96.10) and pharmacology, toxicology & pharmaceutics (from 106.43 to 95.87) from 2007-11 to 2012-16. In terms of citation impact per paper, pharmacology, toxicology & pharmaceutic, among sub-fields, registered the highest CPP of 31.75, followed biochemistry, genetics & molecular biology (16.16) and medicine (10.46) during 2007-16 (Table 4).
