ABSTRACT
Background: The objective of this study is to study the impact of combined use of Alvarado score and computed tomography (CT) scan on negative appendectomy rate.Methods: This prospective observational study comprising of patients presenting with clinical features of appendicitis admitted to department of general surgery, VIMSAR, Burla from November 2017 to October 2019, where Alvarado score and ultrasonography (USG) findings are mismatching each other. Alvarado scores calculated and categorized in 2 groups as negative (score <4) and positive (score ≥4). These patients were also subjected to USG and categorized as negative (USG -ve) and positive (USG +ve). Those patients having discrepancy in both the findings were subjected to CT scan. On histopathological examination, inflamed appendix in 63 (97%) patients and non-inflamed in 2 (3%). Rest patients were either discharged (both -ve) or operated (both +ve). Results: Total 84 patients showed discrepancy between Alvarado score and USG findings and are subjected to CT scan abdomen and pelvis. CT scan was positive for appendicitis in 65 cases (where appendectomy done) and negative for appendicitis in 19 cases (where the diagnosis is different). patient. Thus, negative appendectomy (NAR) is 3% in this study.Conclusions: Alvarado score and ultrasonography could not be used as absolute tool in doubtful and equivocal cases, where combined use of CT scan with Alvarado score and USG has definitely has an edge by diagnosing the differentials and reducing NAR followed by reduction in cost and length of hospital stay.
ABSTRACT
Background: This study is conducted from November 2018 to November 2019 in this institute, where comparison of performance statistics is done between CT scan and Ultrasonography in patients with complicated appendicitis scheduled for conservative management, elective or emergency surgery. Aim of the study was to evaluate and compare the performance statistics of CT scan and Ultrasonography in complicated appendicitis.Methods: The CT scan or USG findings of 87 patients were reviewed. The patients were divided into two groups i.e. CT scan group (group-1/18 patients), USG group (group-2/69 patients). Satistical analysis Student”s t-test, Fischer”s test, p-value, k-value.Results: Clinical signs, CT findings, USG findings, complications at surgery and histological examinations were noted. 2, 3, 13, patients presenting with CT features and 5, 13, 51 patients presenting with USG features of appendicular perforation, peri-appendicular abscess, inflammatory appendicular mass respectively. No clinical signs showed a significant association with the presence of appendicular perforation, peri-appendicular abscess, inflammatory appendicular mass or the complication encountered at surgery.Conclusions: In this study, by comparing CT scan group and USG group in complicated acute appendicitis, CT scan can change the plan of management in doubtful cases, decrease length of hospital stay and expenses, reduce the complication rate and negative laparotomy rate, and reduce the episodes of conversion to open surgery.
