Previous studies have shown regional differences in atrial distensibility. We studied 12 open-chest dogs to test the hypothesis that left atrial compliance is decreased after removal of the left atrial appendage and to determine the effect of altered atrial compliance on atrial reservoir and conduit function. Sonomicrometer crystal pairs were used to measure the long- and short-axis diameters o...

BACKGROUND AND OBJECTIVES To compare laparoscopic appendectomy with traditional open appendectomy. METHODS Seventy-one patients requiring operative intervention for suspected acute appendicitis were prospectively compared. Thirty-seven patients underwent laparoscopic appendectomy, and 34 had open appendectomy through a right lower quadrant incision. Length of surgery, postoperative morbidity ...

OBJECTIVE To compare the efficacy and safety of laparoscopic appendectomy and open appendectomy for acute appendicitis in children. METHODS This study was conducted as a retrospective comparison of hospital records for postoperative complications, duration of operation, and postoperative length of stay between children (aged <18y) who underwent laparoscopic (n=190) or open (n=199) appendectom...

BACKGROUND Appendicitis is a common pediatric condition requiring urgent surgical intervention to prevent complications. Pelvic ultrasound (US) as a diagnostic aid has become increasingly common. Despite its advantages, evidence suggests US can lead to delayed definitive management. OBJECTIVE The objective was to test the hypothesis that US is associated with an increased time to appendectomy...

Abstract Purpose Non-operative treatment (NOT) for pediatric acute appendicitis complicated with intra-abdominal abscess (IAA) has been introduced in the last decade. The study aimed to report our experience this approach and investigate potential predictors of success. Methods Medical records patients affected by IAA between January 2013 December 2020 were reviewed. interval before delayed app...

OBJECTIVES Clinical scoring systems attempt to improve the diagnostic accuracy of pediatric appendicitis. The Pediatric Appendicitis Score (PAS) was the first score created specifically for children and showed excellent performance in the derivation study when administered by pediatric surgeons. The objective was to validate the score in a nonreferred population by emergency physicians (EPs). ...

BACKGROUND In this study, we studied the therapeutic effectiveness of percutaneous drainage with antibiotics and the need for an interval appendectomy for treating appendiceal abscess in children with a research-oriented dataset released by the Bureau of National Health Insurance in Taiwan through the Collaboration Center for Health Information Application (CCHIA). METHODS We identified 1225 ...

BACKGROUND The objective was to conduct a meta-analysis of randomized controlled trials evaluating the efficacy and morbidity of the management of acute uncomplicated (no abscess or phlegmon) appendicitis by antibiotics versus appendectomy. METHODS Appropriate trials were identified. The seven outcome variables were overall complication rate, treatment failure rate for index hospital admissio...

OBJECTIVE To determine the negative appendectomy rate; utilization, accuracy of Alvarado scale, ultrasound (US), computed tomography (CT) in diagnosis of acute appendicitis. METHODS Hospital records of 124 female patients admitted for suspicious of acute appendicitis from January 2003-January 2004 to the Emergency Department (ED) at King Abdul-Aziz University Hospital, Jeddah, Saudi Arabia we...

UNLABELLED INTRODUCTION Acute appendicitis (AA) is common surgical problem associated with acute-phase reaction. Blood tests role in decision-making process is unclear. This retrospective study aimed to determine diagnostic value of preoperative evaluation of white blood cells (WBCs) and neutrophils and its value in predicting AA severity. METHODS Medical records of 456 patients who underw...
