CONTEXT The rates of appendiceal rupture and negative appendectomy in children remain high despite efforts to reduce them. Both outcomes are used as measures of hospital quality. Little is known about the factors that influence these rates. OBJECTIVE To investigate the association between hospital- and patient-level characteristics and the rates of appendiceal rupture and negative appendectom...

OBJECTIVE The aim of this study was to determine the rate of negative appendectomy in a company hospital in Nigeria. BACKGROUND Appendicitis is one of the most common abdominal conditions requiring surgical intervention. Appendectomy, like most surgical procedures, has its complications and therefore should only be undertaken when indicated. Case series have reported the incidence of negative...

BACKGROUND The annual number of pediatric appendectomies in Ontario was stable throughout the study period, but with a significant level of regional variations across regions. The objective of this study is to use population-based data to measure the associations and to explain the variations of appendectomy rates with population socio-demographic indicators. METHODS Appendectomy rates in chi...

OBJECTIVES The objective of this study was to compare usage of computed tomography (CT) scan for evaluation of appendicitis in a children's hospital emergency department before and after implementation of a clinical practice guideline focused on early surgical consultation before obtaining advanced imaging. METHODS A multidisciplinary team met to create a pathway to formalize the evaluation o...

BACKGROUND In this study our aim was to evaluate the diagnostic value of preoperative laboratory and radiological studies for appendicitis. METHODS The clinical data of 196 patients who have undergone conventional appendectomy between March 2007 and April 2008 were collected retrospectively. Patients were examined for age, sex, white blood cell count, ultrasonography results, histopathologica...

BACKGROUND AND OBJECTIVES Diagnostic imaging is often used in the evaluation of children with possible appendicitis. The utility of imaging may vary according to a patient's age and gender. The objectives of this study were (1) to examine the use of computed tomography (CT) and ultrasound for age and gender subgroups of children undergoing an appendectomy; and (2) to study the association betwe...

BACKGROUND Recent theory proposes that the appendix functions as a reservoir for commensal bacteria, and serves to re-inoculate the colon with normal flora in the event of pathogen exposure or purging of intestinal flora. If true, we reasoned that flora from a normal appendix could provide protection against Clostridium difficile. We conducted this investigation to examine the protective effect...
