Introduction: Same-day discharge (SDD) protocols after pediatric laparoscopic appendectomy have not been well studied in a community hospital setting, especially when hospitals with low inpatient pediatric censuses are increasingly closing their pediatric units. This study evaluates the outcomes of a SDD protocol after pediatric appendectomy that was implemented across an integrated healthcare system in which hospitals experienced closure of pediatric units.

Methods: Patients between ages 6 to 13 years-old who underwent laparoscopic appendectomy for uncomplicated appendicitis from January 1st 2015 to December 31st 2020 were reviewed.

the causative organism of Q fever, has been increasingly reported to be associated with infections of abdominal aortic aneurysms and endovascular stent grafts. We have added to the current literature by presenting a case of the surgical management of chronic Q fever that had infected a prior aortic endovascular stent graft placed for a contained rupture of an infrarenal aortic aneurysm in a 68-year-old woman. We presented our case of the surgical management of the excision and explantation of the infected aorta and stent graft, with reconstruction of the aorta using a cryopreserved aortic graft and visceral artery pump perfusion.

Purpose: Intercostal Nerve Cryoablation (INC) has significantly improved pain control following the Nuss repair of pectus excavatum (PE). This study sought to evaluate patients undergoing the Nuss repair with INC compared to the Nuss repair with an ERAS protocol, INC, and intercostal nerve blocks (INB).

Methods: In June 2020, a new protocol was implemented involving surgery, anesthesia, nursing, physical therapy, and child life with the goal of safe same day discharge for patients undergoing the Nuss repair.

Purpose: The use of intercostal nerve cryoablation (INC) has been an effective modality for treating pain in patients undergoing pectus excavatum (PE) repair. This study sought to evaluate if PE patients undergoing Nuss procedures with INC and intercostal nerve block (INB) could safely be discharged the same day of surgery.

Methods: A prospective study with IRB approval of 15 consecutive patients undergoing PE Nuss repair with INC, INB, and an enhanced recovery after surgery (ERAS) protocol was conducted.

Purpose: The use of intercostal nerve cryoablation (INC) is becoming increasingly common in patients undergoing pectus excavatum (PE) repair. This study sought to evaluate the use of INC compared to traditional use of thoracic epidural (TE).

Methods: A retrospective review of 79 patients undergoing PE repair with either INC or TE from May 2009 to December 2019 was conducted.

Objective: This study aims to define risk factors as well as their association with microbiology and clinical outcomes in a large US infective endocarditis population.

Methods: Hospital records were searched for appropriate infective endocarditis-related ICD codes from 16 July 2007 to 13 August 2015. A total of 363 cases were retrospectively identified that met definite Modified Duke Criteria for infective endocarditis and were analyzed by age group, causative organism, and associated risk factors for use of valvular surgical intervention, 30/90/180-day mortality after admission, and embolic phenomena.
