Five Year Trends in the Utilization of Robotic Bariatric Surgery Procedures,United States 2015–2019

Purpose

Robotic approaches have been steadily replacing laparoscopic approaches in metabolic and bariatric surgeries (MBS); however, their superiority has not been rigorously evaluated. The main goal of the study was to evaluate the 5-year utilization trends of robotic MBS and to compare to laparoscopic outcomes.

Methods

Retrospective analysis of 2015–2019 MBSAQIP data. Kruskal-Wallis test/Wilcoxon and Fisher’s exact/chi-square were used to compare continuous and categorical variables, respectively. Generalized linear models were used to compare surgery outcomes.

Results

The use of robotic MBS increased from 6.2% in 2015 to 13.5% in 2019 (N= 775,258). Robotic MBS patients had significantly higher age, BMI, and likelihood of 12 diseases compared to laparoscopic patients. After adjustment, robotic MBS patients showed higher 30-day interventions and 30-day readmissions alongside longer surgery time (26–38 min).

Conclusion

Robotic MBS shows higher intervention and readmission even after controlling for cofounding variables.

Graphical Abstract

     

Acquired supravalvar membranous stenosis of the left atrioventricular valve

Acquired supravalvar membranous stenosis of the left atrioventricular valve developed in a nine year old boy with atrioventricular discordance. The supravalvar membrane had not been present when a partial annuloplasty was performed on the left atrioventricular valve eight years before. The stenosis was relieved by operative excision of the membrane.     

二甲亚砜对人表皮的核酸和蛋白质合成的影响

用体外培养的人的伪表皮作为模型，进行药物毒理学作用的研究，观察了二甲亚砜（ＤＭＳＯ）在不同浓度和不同接触时间条件下，对人的伪表皮细胞脱氧核糖核酸（ＤＮＡ）、核糖核酸（ＲＮＡ）和蛋白质合成的影响：随着接触时间的延长，ＤＮＡ、ＲＮＡ和蛋白质合成均受抑制。低浓度条件下（１％），ＤＮＡ、ＲＮＡ和蛋白质合成增加；在１５～５０％浓度下，ＤＮＡ和蛋白质合成抑制，而ＲＮＡ合成仍增加；在高浓度条件下（７０％～１００％），ＤＮＡ、ＲＮＡ和蛋白质合成均明显抑制。     

Subarachnoid-pleural fistula. Case report and review of the literature

A case is described of a subarachnoid-pleural fistula developing after resection of an intrathoracic benign nerve sheath tumor near the eleventh thoracic vertebra. The fistula was demonstrated by myelography and was corrected surgically. Of 12 previously reported cases, 11 occurred after trauma and one after an operation.     

Case Report: 49, XXXXY syndrome and high myopia

49, XXXXY karyotype syndrome has been thought of as a variant of Klinefelter's syndrome. It has an incidence of between 1/85 000 to 1/100 000 live births. Typical clinical features include coarse faces, skeletal abnormalities, hypogenitalism and severe learning difficulties. Common ocular features include hypertelorism, epicanthic folds and up-slanting palpebral apertures. Here we report a case of high myopia and its successful correction leading to a positive personality change in one such patient. We advocate full ophthalmic examination, under anaesthesia if necessary, and a trial of refractive correction, even in children thought unlikely to tolerate such.
