Abstract
Background: The present study aimed to compare outcomes between cholecystectomy on index versus delayed admission for acute cholangitis. Methods: The 2011-2020 Nationwide Readmissions Database was used to identify adult patients admitted for acute cholangitis who underwent cholecystectomy. Study cohorts were defined based on timing of surgery. Multivariable regressions and Royston-Parmar time-adjusted analysis were used to evaluate the association of cholecystectomy timing and outcomes. Results: Of 65,753 patients, 82.0 % received surgery on Index and 18.0 % on Delayed admissions. Following adjustment, Delayed operation was associated with significantly increased odds of mortality (AOR 1.67 [95 % CI 1.10-2.54]), complications (1.25 [1.13-1.40]), repair of bile duct injury (1.66 [1.15-2.41]), conversion to open (1.69 [1.48-1.93]), and 30-day readmission (3.52 [3.21-3.86]). The Delayed cohort experienced a & thorn;$14,200 increment in hospitalization costs relative to Index. Conclusions: Delayed cholecystectomy for acute cholangitis is significantly associated with adverse postoperative outcomes, suggesting that index cholecystectomy may be safe to perform.

- Pretraining has recently greatly promoted the development of natural language processing (NLP)
- We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
- We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
- The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
- Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
