OBJECTIVE This study aimed to investigate the relationship between appendiceal orifice inflammation (AOI) and appendectomy and ulcerative colitis (UC) by a meta-analysis. METHODS Databases were thoroughly searched for studies on AOI and UC up to January 2016. Three comparisons were performed: a) whether the previous appendectomy was a risk factor of UC; b) influence of appendectomy on UC cour...
BACKGROUND Although laparoscopic appendectomy is widely practiced in developed countries, still there are many questions regarding the advantages and disadvantages of this approach in the treatment of acute appendicitis. Several controlled trials have been conducted, some in favor of laparoscopic appendectomy others not. The aim of this study was to evaluate laparoscopic appendectomy in compari...
CONTEXT Misdiagnosis of presumed appendicitis is an adverse outcome that leads to unnecessary surgery. Computed tomography, ultrasonography, and laparoscopy have been suggested for use in patients with equivocal signs of appendicitis to decrease unnecessary surgery. OBJECTIVE To determine if frequency of misdiagnosis preceding appendectomy has decreased with increased availability of computed...
It is believed that the appendix will be perforated if the surgery of an acute appendicitis is delayed. However, some of the recent studies, contested this hypothesis and shown that only a delay in the treatment cannot fully explain perforated appendicitis. This study aimed to examine the prevalence and risk factors for perforated appendicitis in patients with acute appendicitis. A cross-sectio...
conclusions sils appendectomy can be successfully performed by trainees on all-comers with comparable resource utilisation and clinical outcomes to those achieved by junior trainees performing a conventional three-port laparoscopic approach. results seventeen patients had sils operations: 15 appendectomies, one resection of inflamed meckel’s diverticulum and one appendectomy with oophorectomy. ...
INTRODUCTION Several European studies suggest that some patients with appendicitis can be treated safely with antibiotics. A portion of patients eventually undergo appendectomy within a year, with 10%-15% failing to respond in the initial period and a similar additional proportion with suspected recurrent episodes requiring appendectomy. Nearly all patients with appendicitis in the USA are stil...
BACKGROUND Removal of the appendix might induce physiological changes in the gastrointestinal tract, and subsequently play a role in carcinogenesis. Therefore, we conducted a nationwide register-based cohort study in Sweden to investigate whether appendectomy is associated with altered risks of gastrointestinal cancers. METHODS A population-based cohort study was conducted using the Swedish n...
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...
