Surgery metaanalysis

J P Windfuhr
BACKGROUND: One of the most significant clinical trials, demonstrating the efficacy of tonsillectomy (TE) for recurrent throat infection in severely affected children, was published in 1984. This systematic review was undertaken to compile various indications for TE as suggested in the literature after 1984 and to stratify the papers according to the current concept of Evidence-based Medicine. MATERIAL AND METHODS: A systematic Medline research was performed using the key word "tonsillectomy" in combination with different filters such as "systematic reviews", "meta-analysis", "English", "German" and "from 1984/01/01 to 2015/05/31"...

UNLABELLED: We performed a metaanaysis of peer-reviewed studies involving implantation of a multifocal intraocular lens (IOL) in presbyopic patients with cataract or having refractive lens exchange (RLE). Previous reviews have considered the use of multifocal IOLs after cataract surgery but not after RLE, whereas greater insight might be gained from examining the full range of studies. Selected studies were examined to collate outcomes with monocular and binocular uncorrected distance, intermediate, and near visual acuity; spectacle independence; contrast sensitivity; visual symptoms; adverse events; and patient satisfaction...

UNLABELLED: To evaluate the accuracy of intraocular lens (IOL) power calculation methods after laser refractive surgery in myopic eyes, a comprehensive literature search was carried out for retrospective case series studies with data on post-myopic laser surgery IOL power calculations published from January 2000 to May 2014. A metaanalysis of the 9 identified studies was performed using odds ratios in percentage of prediction error within ±0.5 or 1.0 diopter (D) of the target refraction...

Changes in tumor metabolic activity have been shown to be an early indicator of treatment effectiveness for breast cancer, mainly in the neoadjuvant setting. The histopathologic response at the completion of chemotherapy has been used as the reference standard for assessment of the accuracy of (18)F-FDG PET in predicting a response during systemic treatment. Although a pathologic complete response (pCR) remains an important positive prognostic factor for an individual patient, a recent metaanalysis could validate pCR as a surrogate marker for patient outcomes only in aggressive breast cancer subtypes...

UNLABELLED: We conducted a systematic review and metaanalysis to provide evidence-based recommendations on the value of early postoperative review. We identified 3 randomized controlled trials (RCTs) that compared patients seen on the first postoperative day with those reviewed at 2 weeks; the 3 studies comprised 886 patients. The risk for postoperative complications was lower when review was deferred 2 weeks because of early transient pressure spikes. There was no difference in the number of unscheduled visits during the first 2 weeks postoperatively or the visual acuity at follow-up...

Atrial fibrillation (AF), which increases morbidity and mortality, is a common occurrence after thoracic surgery and pulmonary resection. Despite several investigations on various prophylactic measures for AF prevention, the studies were not uniform and do not use similar controls making it difficult to arrive at a meaningful conclusion. In the present systematic analysis review, we evaluated the efficacy of different prophylactic approaches to prevent AF after lung surgery in randomized trials reported during 1991-2014...

INTRODUCTION: Enhanced recovery pathways have been widely accepted and implemented for different types of surgery. Their overall effect in abdominal gynecologic surgery is still underdetermined. A systematic review and meta-analysis were performed to provide an overview of current evidence and to examine their effect on postoperative outcomes in women undergoing open gynecologic surgery. MATERIAL AND METHODS: Searches were conducted using Embase, Medline, CINAHL, and the Cochrane Library up to 27 June 2014...

UNLABELLED: This review looked at the effect of cataract surgery on the regulation of circadian rhythms and compared the effect of blue light-filtering and clear intraocular lenses (IOLs) on circadian rhythms. A systematic review and metaanalysis were performed, and the level of evidence was evaluated based on the principles described in the Grading of Recommendations Assessment, Development, and Evaluation system. A literature search of PubMed, Embase, and Cochrane Library databases was performed, as well as a search for unpublished trials at the U...

UNLABELLED: Relatively new evidence suggests that movement representation techniques (ie, therapies that use the observation and/or imagination of normal pain-free movements, such as mirror therapy, motor imagery, or movement and/or action observation) might be effective in reduction of some types of limb pain. To summarize the evidence regarding the efficacy of those techniques, a systematic review with meta-analysis was performed. We searched Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, CINAHL, AMED, PsychINFO, Physiotherapy Evidence Database, and OT-seeker up to August 2014 and hand-searched further relevant resources for randomized controlled trials that studied the efficacy of movement representation techniques in reduction of limb pain...

BACKGROUND: Analyze the most important prognostic factors when performing periapical surgery and compare the success rates of distinct authors. INTRODUCTION: Periapical surgery is an approach to treat non-healing periapical lesions and it should be viewed as an extension of endodontic treatment and not as a separate entity. MATERIAL AND METHODS: A search of articles published in Cochrane, PubMed (MEDLINE) and Scopus was conducted with the key words "prognostic factors", "prognosis", "periapical surgery", "endodontic surgery" and "surgical endodontic treatment"...

This review was conducted to compare the physical effect of aspheric IOL implantation on wavefront properties with that of spherical IOL implantation. The peer-reviewed literature was systematically searched in Medline, Embase, Web of Science, Biosis, and the Cochrane Library according to the Cochrane Collaboration method. Inclusion criteria were randomized controlled trials comparing the use of aspheric versus spherical monofocal IOL implantation that assessed visual acuity, contrast sensitivity, or quality of vision...

BACKGROUND CONTEXT: Spine surgery is usually associated with large amount of blood loss, necessitating blood transfusions. Blood loss-associated morbidity can be because of direct risks, such as hypotension and organ damage, or as a result of blood transfusions. The antifibrinolytic, tranexamic acid (TXA), is a lysine analog that inhibits activation of plasminogen and has shown to be beneficial in reducing surgical blood loss. PURPOSE: To consolidate the findings of randomized controlled trials (RCTs) investigating the use of TXA on surgical bleeding in spine surgery...

OBJECTIVES: Postcardiac surgery delirium is associated with increased risks of morbidity, cognitive decline, poor health-related quality of life and mortality, and higher healthcare costs. We performed a systematic review of randomized controlled trials to examine the effect of pharmacologic agents for the prevention and the treatment of delirium after cardiac surgery. DATA SOURCES: Electronic search on PubMed, Medline, Embase, Cochrane Central Register of Controlled Trials, ISI Web of Science, and CINAHL up to December 2013...

PURPOSE OF THE STUDY: The aim of the study was to compare two surgical methods of treating diaphyseal fractures of the humerus. MATERIAL AND METHODS: A prospective randomised study on the surgical treatment of humeral diaphyseal fractures was carried out between September 2009 and January 2013. The patients indicated for surgical treatment fell into two groups according to the technique used as follows: minimally invasive plate osteosynthesis (MIPO) with a locking compression plate (LCP; Synthes, Switzerland); depending on the fracture type and course of fracture line, either a straight narrow or a Philos or a metaphyseal LCP was used (group 1); and intramedullary nailing (EHN, Synthes, Switzerland) (group 2)...

OBJECT: Information pertaining to the natural history of intramedullary spinal cord cavernous malformations (ISCCMs) and patient outcomes after surgery is scarce. To evaluate factors associated with favorable outcomes for patients with surgically and conservatively managed ISCCMs, the authors performed a systematic review and metaanalysis of the literature. In addition, they included their single-center series of ISCCMs. METHODS: The authors searched MEDLINE, EMBASE, CINAHL, Google Scholar, and The Cochrane Library for studies published through June 2013 that reported cases of ISCCMs...
