In a comparative analysis of an electronic health record-based machine learning model and established clinical risk scores for gastrointestinal bleeding, researchers found the model significantly outperformed the Glasgow-Blatchford Score and Oakland Score. With an area under the receiver-operating-characteristic curve (AUC) of 0.92 versus 0.89 (p

AI Model Effectively Quantifies Residual Pancreatic Cancer Post-Treatment
Development and validation of the ISGPP model marks a significant advancement in automating residual pancreatic cancer (RPC) quantification. The model demonstrated robust performance across diverse scanners, achieving mean F1 scores of 0.81-0.71 upon validation. A comprehensive dataset of 528 unique H&E slides from 528 patients facilitated training the model, which is now publicly available. This […]
Preoperative dexamethasone enhances recovery in emergency laparotomy
A single high dose of intravenous dexamethasone prior to emergency laparotomy significantly reduces postoperative inflammatory responses, as shown by lower C-reactive protein levels (median 170 vs. 220 mg/l, p = 0.015). This administration correlates with enhanced recovery indicators, such as improved hemodynamics and earlier mobilization. The dexamethasone group also experienced a notable decrease in 90-day […]
Simulation assessment effectively distinguishes surgical trainee competence levels
A novel simulation-based assessment of operative competence was developed, demonstrating high inter-station reliability (α = 0.81) and acceptable inter-rater reliability (0.77). Significant differences emerged in mean scores between junior and senior trainees (44.82 vs 58.18, p = 0.004), with mean scores moderately correlating with training years (rs = 0.74, p = 0.004). The assessment resulted […]
Screening Patients Reduces Pancreatic Cancer Mortality Rates
Elevated-risk patients for pancreatic ductal adenocarcinoma (PDAC) who underwent guideline-based screening achieved significantly improved overall survival compared to non-screened counterparts. Among 826 patients, those in the high-risk clinic experienced longer median survival rates, with 68% diagnosed at stage 0 versus 31% in the surgical oncology group. Overall survival post-resection was also notably higher in high-risk […]
Cold snare resection is safer than hot methods for polyps.
In a randomized controlled trial involving 363 patients with large nonpedunculated colorectal polyps, cold endoscopic mucosal resection (EMR) demonstrated a significantly lower rate of major adverse events (1.0%) compared to hot EMR (7.9%, p = .001). While cold resection did result in a higher rate of residual adenoma (23.7% vs 13.8%, p = .020), safety […]
New technique offers safer, simpler treatment for fissures
Transmucosal internal sphincterotomy demonstrates significant advantages in treating fissure in ano compared to traditional methods. The procedure had a median operative time of 7 minutes, yielding a mere 2.5% infection rate and 3% transient incontinence rate. Postoperative pain was notably lower, with a majority of patients healing within 9 weeks and only 1.6% experiencing recurrence. […]
Innovative technique ensures safety in laparoscopic caudate lobectomy
With a remarkable 0% conversion and mortality rate, the “easy first” technique for laparoscopic hepatic caudate lobectomy has shown promise in safety and effectiveness. By employing sextet strategies—meticulous planning, optimal trocar placement, and efficient team positioning—clinicians can tackle the complexities of the caudate lobe. The study emphasizes the necessity of proper patient selection and advanced […]
Hypoalbuminemia increases 30-day complications post-pancreaticoduodenectomy.
A retrospective analysis of 25,848 pancreaticoduodenectomy patients revealed that 10.5% had preoperative hypoalbuminemia, which significantly correlated with increased 30-day complications. Specifically, hypoalbuminemic patients faced higher risks for serious complications (OR 1.80) independent of other comorbidities but did not have increased mortality risk (OR 1.37). The median age of hypoalbuminemic patients was notably higher, and many […]
New neural network enhances drug discovery for surgical treatments
A novel attention-based convolution transpositional interfusion network (ACTIN) has shown promising results for drug discovery with limited data. Utilizing just 393 training instances, ACTIN achieved state-of-the-art performance by leveraging graph convolution and transformer mechanisms to analyze drug and transcriptome data. It identifies pharmacophores that may benefit surgical patients, aiming to reduce complications and expedite recovery. […]
