Global trends in research on Roux-en-Y gastric bypass treatment for morbid obesity
Objective To analyze the research direction and hotspots of Roux-en-Y gastric bypass(RYGB)surgery.Methods Publications related to RYGB from 2012 to 2022(excluding 2022)were retrieved from the Web of Science,and bibliometric methods were used to statistically analyze the growth trends of publications and contributions of countries/regions to global publications,institutions,authors,and journals.Data were processed and visualized using the bibliometric package in R software 4.2.1 and VOSviewer 1.6.18 software.Results A total of 4 219 articles were included for analysis.Over the past ten years,the number of publications on RYGB has steadily increased(R2=0.959 9).The highest number of RYGB-related research publications were published in the journal Obesity Surgery.The United States contributed the most to RYGB research in the field of bariatric surgery and had relatively more interactions with other countries/regions.The highest co-citation analysis revealed that RYGB for treating obesity-related type 2 diabetes is a frequently discussed topic among researchers.Further analysis of research on type 2 diabetes demonstrates its close association with weight loss.Articles with higher citation frequencies focus on complications,mortality,revision surgeries,and weight regain.Analysis of the weight regain research indicated that researchers were concerned with morbid obesity.Conclusions Although the number of RYGB surgeries has declined,key topics in metabolic research,such as type 2 diabetes,revisional surgery,weight regain,and complications continue to drive interest among researchers.This sustained interest underscores ongoing efforts to explore the mechanisms,benefits,limitations,and applicability of RYGB across diverse populations.
