Abstract We performed a bibliometric analysis of Latin American documents published between 1984 to 2019 in Scopus-indexed journals. A total of 1856 documents were analyzed. The annual scientific production was 64 documents per year, with an annual increase rate of 15.9%. The countries with the highest scientific production on BS were Brazil (64.7%) and Chile (14.5%). Most of the publications were original (76.6%) and review articles (11.9%). The journal with the highest publication record was “Obesity Surgery” (25.8%). The extra-regional collaboration was mainly with the USA. In conclusion, Latin American scientific production on BS has shown a significant increase in recent years. However, more participation is needed, fostering intra-regional collaboration and involving universities and health institutions in BS research. Keywords Bariatric surgery . Obesity . Bibliometrics .

Introduction In recent years, Bariatric Surgery (BS) has expanded worldwide [1]. This has been reflected in the increase of members in surgical societies [2] and the number of scientific publications in this area [3]. Latin America (LA) has been a leader in the innovation of surgical techniques in BS [4], with Brazil being the country with the highest contribution in the area [3].

Bibliometric analysis is an effective method for measuring scientific contributions in a variety of fields [5]. BS is not the exception and evaluating the collaboration networks, characteristics of quantity (current trends and scope), and quality (rates of citations and level of evidence) of scientific production [6, 7] allows to identify gaps in knowledge. Furthermore, it can direct research towards important unaddressed questions, promoting effective government investment policies [8]. It is important to note that the bibliometric studies of BS conducted to date [3, 9, 10] have some limitations. First, they only included Web of Science (WoS) in their s
