Article Abstract
Background: Robotic Roux-en-Y gastric bypass (RRYGB) is performed in an increasing number of bariatric centers worldwide. Previous studies have identified a number of demographic and clinical variables as predictors of postoperative complications after laparoscopic Roux-en-Y gastric bypass (LRYGB). Some authors have suggested better early postoperative outcomes after RRYGB compared to LRYGB. The objective of the present study was to assess potential predictors of early postoperative complications after RRYGB.
Methods: A retrospective analysis of two prospective databases containing patients who underwent RRYGB between 2006 and 2019 at two high volumes, accredited bariatric centers was performed. Primary outcome was rate of 30 day postoperative complications. Relevant demographic, clinical and biological variables were entered in a multivariate, logistic regression analysis to identify potential predictors.
Results: Data of 1276 patients were analyzed, including 958 female and 318 male patients. Rates of overall and severe 30 day complications were 12.5% (160/1276) and 3.9% (50/1276), respectively. Rate of 30 day reoperations was 1.6% (21/1276). The overall gastrointestinal leak rate was 0.2% (3/1276). Among various demographic, clinical and biological variables, male sex and ASA score >2 were significantly correlated with an increased risk of 30 day complication rates on multivariate analysis (OR 1.68 and 1.67, p=0.005 and 0.005, respectively).
Conclusion: This study identified male sex and ASA score >2 as independent predictors of early postoperative complications after RRYGB. These data suggest a potentially different risk profile in terms of early postoperative complications after RRYGB compared to LYRGB. The robotic approach might have a benefit for patients traditionally considered to be at higher risk of complications after LRYGB, such as those with BMI >50. The present study was however not designed to assess this hypothesis and larger, prospective studies are necessary to confirm these results.

Department of Auricular Reconstruction, Plastic Surgery Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing, China.
Background: Congenital accessory auricle is a common aurcile malformation, often associated with tragus malformation, impacting the appearance and psychology of patients. To optimize surgical treatments for congenital accessory auricle with tragus malformation, this article proposes a novel classification and explores surgical strategies.
Methods: This retrospective study included 120 patients with congenital accessory auricle and tragus malformation who underwent surgery between December 2019 and June 2024.
A Retrospective Review of Craniosynostosis Reconstruction at a Community Children's Hospital Compared With Academic Centers.
J Craniofac Surg
September 2025
Department of Pediatric Plastic and Reconstructive Surgery, Children's Hospital Colorado.
Background: Craniosynostosis repair is traditionally performed at high-volume academic centers with multidisciplinary teams. Access barriers in rural or suburban regions raise the question of whether comparable outcomes can be achieved and if this surgery can be performed safely in community settings.
Objective: To evaluate the safety and perioperative outcomes of cranial vault reconstruction for craniosynostosis performed at a community-based children's hospital and compare these outcomes to those reported at academic institutions.

Viterbi Family Department of Ophthalmology, Division of Oculofacial Plastic and Reconstructive Surgery, Shiley Eye Institute, University of California, San Diego.
This study evaluates the clinical presentation, surgical management, and outcomes of silent sinus syndrome (SSS), with emphasis on the efficacy of simultaneous sinus and orbital surgery. A retrospective review was performed of 35 patients diagnosed with SSS at a tertiary care center between January 2004 and April 2024. All patients had radiographic evidence of maxillary sinus atelectasis and orbital floor resorption.
