BACKGROUND Clinical evaluation alone is still considered adequate by many clinicians who treat patients with appendicitis. The impact of computed tomography (CT) on clinical outcomes remains unclear, and there is no consensus regarding the appropriate use of CT in these patients. We sought to evaluate the impact of abdominal CT on the clinical outcomes of patients presenting with suspected appe...

BACKGROUND This retrospective study aimed to evaluate the ability of the delta neutrophil index (DNI) to predict histologically normal appendicitis preoperatively and to differentiate between simple and complicated appendicitis. METHODS The data from 650 patients were divided into positive and negative appendectomy groups (histologically normal appendicitis). The patients in the acute appendi...

OBJECTIVES To evaluate the short-term outcome of open appendectomy, the rate of negative appendectomy as well as pathology reports after surgery in patients with suspected acute appendicitis. METHODS This was a retrospective cross-sectional study being performed in Nemazee hospital affiliated with Shiraz University of Medical Science during a 2-year period between 2008 and 2010. The medical r...

OBJECTIVES To determine the role of abdominal computed tomography (CT) imaging in patients with right lower quadrant (RLQ) pain. The authors hypothesized that selective use of abdominal CT would reduce imaging without increasing the rates of negative appendectomy and perforated appendicitis. METHODS A prospective randomized clinical trial was conducted in a community teaching emergency depart...

BACKGROUND Acute appendicitis is the most frequent surgical emergency encountered worldwide. This study was conducted to compare the efficacy of Tzanakis score and Alvarado score in diagnosing acute appendicitis. OBJECTIVES The aim of this study is to compare the efficacy of Tzanakis scoring system with Alvarado scoring system in diagnosing AA. METHODS This was a retrospective and nonrandom...

PURPOSE Laparoscopic appendectomy (LA) for acute appendicitis has several advantages over open appendectomy (OA). In cases of complicated appendicitis, LA is converted to OA at a constant rate, though converting appendectomy (CA) has several disadvantages. We retrospectively determined preoperative risk factors for failure of LA and subsequent conversion to OA. METHODS Consecutive cases of pr...

OBJECTIVE The optimal diagnostics and treatment of acute appendicitis continues to be a challenge. A false positive diagnosis of appendicitis may lead to an unnecessary operation, which has been appropriately termed negative appendectomy. The aim of our study was to identify the effectiveness of preoperative investigations in preventing negative appendectomy. METHODS A retrospective study was...

BACKGROUND Clinical diagnosis of acute appendicitis is most difficult in fertile-age women. In this patient group up to 50% of open appendectomies are negative for appendicitis. We conducted a randomized study to compare laparoscopic and open appendectomy in young female patients with suspected acute appendicitis. METHODS Fifty female patients between the ages of 16 and 40 years presenting wi...
