A Systematic Review to Summarise and Appraise the Reporting of Surgical Innovation: a Case Study in Robotic Roux-en-Y Gastric Bypass.

Robotic Roux-en-Y gastric bypass (RRYGB) is an innovative alternative to traditional laparoscopic approaches. Literature has been published investigating its safety/efficacy; however, the quality of reporting is uncertain. This systematic review used the Idea, Development, Exploration, Assessment and Long-term follow-up (IDEAL) framework to assess the reporting quality of available literature. A narrative summary was formulated, assessing how comprehensively governance/ethics, patient selection, demographics, surgeon expertise/training, technique description and outcomes were reported. Forty-seven studies published between 2005 and 2024 were included. There was incomplete/inconsistent reporting of governance/ethics, patient selection, surgeon expertise/training and technique description, with heterogenous outcome reporting. RRYGB reporting was poor and did not align with IDEAL guidance. Robust prospective studies reporting findings using IDEAL/other guidance are required to facilitate safe widespread adoption of RRYGB and other surgical innovations.

Chromosome 22q11.2 Deletion (DiGeorge Syndrome): Immunologic Features, Diagnosis, and Management.

PURPOSE OF REVIEW: This review focuses on immunologic findings, relationships among immunologic findings and associated conditions of autoimmunity and atopy, and management of immunologic disease in chromosome 22q11.2 deletion syndrome (22q11.2DS, historically known as DiGeorge syndrome). RECENT FINDINGS: The implementation of assessment of T cell receptor excision circles (TRECs) in newborn screening has led to increased detection of 22q11.2 deletion syndrome. While not yet applied in clinical practice, cell-free DNA screening for 22q11.2DS also has the potential to improve early detection, which may benefit prompt evaluation and management. Multiple studies have further elucidated phenotypic features and potential biomarkers associated with immunologic outcomes, including the development of autoimmune disease and atopy. The clinical presentation of 22q11.2DS is highly variable particularly with respect to immunologic manifestations. Time to recovery of immune system abnormalities is not well-defined in current literature. An understanding of the underlying causes of immunologic changes found in 22q11.2DS, and the progression and evolution of immunologic changes over the lifespan have expanded over time and with improved survival. An included case highlights the variability of presentation and potential severity of T cell lymphopenia in partial DiGeorge syndrome and demonstrates successful spontaneous immune reconstitution in partial DiGeorge syndrome despite initial severe T cell lymphopenia.

A systematic review of robot-assisted anti-reflux surgery to examine reporting standards.

Robot-assisted anti-reflux surgery (RA-ARS) is increasingly being used to treat refractory gastro-oesophageal reflux disease. The IDEAL (Idea, Development, Exploration, Assessment, Long-term follow up) Collaboration's framework aims to improve the evaluation of surgical innovation, but the extent to which the evolution of RA-ARS has followed this model is unclear. This study aims to evaluate the standard to which RA-ARS has been reported during its evolution, in relation to the IDEAL framework. A systematic review from inception to June 2020 was undertaken to identify all primary English language studies pertaining to RA-ARS. Studies of paraoesophageal or giant hernias were excluded. Data extraction was informed by IDEAL guidelines and summarised by narrative synthesis. Twenty-three studies were included: two case reports, five case series, ten cohort studies and six randomised controlled trials. The majority were single-centre studies comparing RA-ARS and laparoscopic Nissen fundoplication. Eleven (48%) studies reported patient selection criteria, with high variability between studies. Few studies reported conflicts of interest (30%), funding arrangements (26%), or surgeons' prior robotic experience (13%). Outcome reporting was heterogeneous; 157 distinct outcomes were identified. No single outcome was reported in all studies.The under-reporting of important aspects of study design and high degree of outcome heterogeneity impedes the ability to draw meaningful conclusions from the body of evidence. There is a need for further well-designed prospective studies and randomised trials, alongside agreement about outcome selection, measurement and reporting for future RA-ARS studies.
