Purpose: Limited data exists evaluating same-day discharge for pediatric Nuss procedure; most being single-center studies. Our analysis, using the NSQIP-P registry, aimed to assess if same-day discharge for the Nuss procedure influenced post-operative outcomes.

Methods: The NSQIP-P database (2017-2022) identified patients who underwent the Nuss procedure.

Purpose: Practice patterns of same-day discharge for pediatric laparoscopic appendectomy for non-perforated appendicitis are not well-analyzed. Our aim is to evaluate current practice patterns and outcomes of same-day discharge for these patients.

Methods: NSQIP-P retrospective registry identified patients (2017-2021) who underwent laparoscopic appendectomy for non-perforated appendicitis.

The utilization of oxygen transport membranes enables the production of high-purity hydrogen by the thermal decomposition of water below 1000 °C. This process is based on a chemical potential gradient across the membrane, which is usually achieved by introducing a reducing gas. Computational fluid dynamics (CFD) can be used to model reactors based on this concept.

Background: The usage of specific ICD-10 diagnosis codes significantly influences hospital reimbursement compared to non-specific codes. This study hypothesized that a formal orientation program for pediatric surgery residents would enhance the selection of accurate and specific diagnosis codes for acute appendicitis such as K35.30 for "Acute appendicitis with localized peritonitis" rather than K35.

Background: There is limited literature on optimal timing for elective thoracoscopic lobectomy for congenital pulmonary airway malformations (CPAM) and sequestration. Using NSQIP-P, we aim to assess optimal operative timing for elective thoracoscopic lobectomy for CPAM and sequestration.

Methods: Data from the NSQIP-Pediatric registry was used to evaluate elective thoracoscopic lobectomy patients from 2017 to 2021 diagnosed with congenital pulmonary airway malformation or sequestration.
