Background: Bibliometric analysis is an effective method for measuring scientific contributions in a variety of fields. It enables the numerical analysis of publications in a specific field and period of time, as well as the relationships between these publications. The present bibliometric analysis of publications relating to obesity treatment by means of intragastric balloons aimed to identify the bariatric centers using intragastric balloons, through the publications relating to their productivity; and furthermore, to reveal collaborations, types of balloons used, number of patients involved, and authors' productivity and favored journals. Method: The PubMed and Scopus databases were used to retrieve only original articles presenting the results in body weight reduction. Results: Bibliographic research identified 164 publications for the period 2000–2021. Italy was ranked first with 37 publications; USA participated as collaborator with 9 different countries; the fluid-filled Orbera balloon is featured in 126 publications; the journal Obesity Surgery hosted 86 publications; Brazil reported the greatest number of patients with 5874 cases; Lorenzo M and Genco A, co-authors from Italy, authored 14 and 12 publications, respectively, and the most cited article was that of Genco et al. [2007] with 441 citations. Conclusions: Bibliometric analysis gave us the opportunity to identify the centers through their scientific publications and to classify them in relation to their productivity in articles, in collaborations, in number of cases reported, and in the number of citations gained.

Purpose: Intraoperative imaging of parathyroid glands (PGs) has been developed in order to reduce the risk of unintentional parathyroidectomy during total thyroidectomy. This novel modality is based on their intrinsic characteristic of autofluorescence (AF) after near-infrared light exposure. The aim of this study was to assess the effect of this method on the risk of unintentional PG excision (total or partial) during total thyroidectomy. Methods: This was a single-blind, randomized-controlled trial including adult patients who underwent scheduled total thyroidectomy between December 2019 and March 2020. These patients were randomly allocated to two groups: one in which near-infrared autofluorescence imaging (NIRAF) was applied (NIR group) and one without NIRAF (NONIR group). Hormonal and biochemical assessment was performed pre- and 24-h postoperatively. AF findings and the number of PGs autotransplanted were recorded. Results: One-hundred and eighty patients were eligible. Unintentional (total or partial) PG excision rates during total thyroidectomy in the NONIR (n = 90) and NIR (n = 90) groups were 28.9% [95% confidence interval (CI) 19.8–39.4%] and 14.4% (95% CI 7.7–22.1%), respectively (p = 0.02). Furthermore, NIR reduced the risk of parathyroid tissue presence in the specimen sent for pathology (relative risk 0.51, 95% CI 0.28–0.92; p = 0.02). However, the number of PGs identified by NIR could not predict the risk of postoperative hypoparthyroidism. Conclusions: NIRAF imaging during total thyroidectomy led to a significant reduction in PG excision rates. However, this modality did not result in the reduction of postoperative hypoparathyroidism or hypocalcemia risk. [ABSTRACT FROM AUTHOR]

Purpose: The increased experience of a thyroid surgeon reduces the risk of postoperative complications. However, whether it is also cost-effective is currently unknown. The aim of the present study was to compare cost-effectiveness of high-volume (HVS) with low-volume surgeons (LVS) when performing a total thyroidectomy. Methods: This was a retrospective study, comparing the mean cost of a total thyroidectomy per patient, between HVS and LVS. This included the cost of surgical procedure and pre- and post-operative inpatient hospitalization. A threshold of 25 thyroidectomies/year was used to discriminate between HVS and LVS. Results: Four-hundred and forty-one patients were classified into HVS and 342 into the LVS group. With regard to surgical complications, higher rates of temporary hypoparathyroidism and endangered airway were observed in the LVS than in the HVS group. The estimated total cost per patient was higher in the LVS compared with the HVS group [€1721 ± 396 ($1910 ± 439) versus €979 ± 68 ($1086 ± 487); p < 0.0001]. This cost remained higher when sub-analysis was performed for each surgical stage, involving either surgical procedure or pre- and post-operative inpatient hospitalization. Differences between LVS and HVS mainly involved the cost in surgical procedure (23% attributed to occupation of the operating room) and postoperative inpatient hospitalization (45% of the total thyroidectomy cost). Conclusion: Total thyroidectomy performed by a HVS seems to be cost-effective compared with the one conducted by LVS. This is mostly attributed to the lower rates of surgical complications, such as postoperative hypoparathyroidism and airway obstruction. [ABSTRACT FROM AUTHOR]
