Introduction: Conflicting reports exist about the effect obesity has on adverse postoperative surgical outcomes after distal pancreatectomy (DP). The aim of this study is to explore the role of obesity in terms of morbidity and pancreas-specific complications following DP for pancreatic ductal adenocarcinoma (PDAC).
Methods: All patients who underwent DP at a single institution over 10 y were analyzed (2009-2020). Patients were categorized as nonobese (body mass index [BMI] < 30 kg/m) and obese (BMI ≥ 30 kg/m). Independent predictors of adverse postoperative outcomes were calculated using multivariate logistic regression models. Overall survival was assessed using Kaplan-Meier survival analysis.
Results: Of the 178 patients included, 58 (32.5%) were obese. Clinically relevant postoperative pancreatic fistula (CR-POPF) formation rate was significantly higher in the obese group (20.6% versus 7.5%, P value = 0.011). We did not identify any significant difference between obese and nonobese patients in median overall survival (30.2 mon versus 28.9 mon, P value = 0.811). On multivariate binary logistic regression analysis, BMI ≥ 30 was an independent predictor of morbidity (any complication) and CR-POPF formation after DP for PDAC.
Conclusions: Obesity is associated with a significantly increased risk for CR-POPF in patients undergoing DP for PDAC. Obesity should be considered as a variable in fistula risk calculators for DP.

Background: Atrial septal defects (ASDs) are a common cause of congenital heart disease worldwide.
Objectives: The purpose of the study was to assess change over time in surgical outcomes for ASD repair and identify patient-level risk factors for adverse postoperative outcomes.
Methods: We analyzed cases of isolated ASD in patients <18 years from 2010 to 2020 from 71 sites participating in the International Quality Improvement Collaborative for Congenital Heart Disease.

Introduction: Perioperative neurocognitive dysfunction (PND) is a significant challenge for patients who need surgery worldwide. Morphine can trigger an intense inflammatory reaction in the central nervous system (CNS) at the same time as analgesia, thus adverse effects aggravating PND. Microglia polarization is closely involved in the regulation of neuroinflammation and the TLR4/MyD88/NF-κB signaling pathway.

Introduction: Perioperative optimization of Crohn's disease (CD) patients is mandatory in order to ensure favorable outcomes and limit perioperative morbidity such as anastomosis-related complications. The use of perioperative tacrolimus may offer beneficial inflammatory control and improve postoperative outcome. However, it also may exhibit unwanted effects of immunosuppression on infectious complications and wound healing.

Coronary heart disease (CHD) remains a leading cause of mortality in Indonesia, and coronary artery bypass graft (CABG) surgery is frequently employed to manage arterial blockages. Despite its efficacy, the recurrence of heart disease post-surgery is a significant concern, highlighting the need for a deeper understanding of its influencing factors. The aim of this study was to examine the factors associated with the incidence of heart disease recurrence after coronary bypass surgery.
