Examination of the relationship between preoperative ct morphometry and periappendiculer CT values and perforation of appendicitis in confirmed diagnosis of acute appendicitis patients,

Acute appendicitis is a most common acute abdominal disease. Perforation rates of acute appendicitis are still around 20%. In the literature count and scope of works, describing values that increase the perforation and relationship between appendicitis perforation with CT, aren't enuogh. The aim of our study is to evaluate this relationship and to identify surgical priorities and to prevent perforation and complications. In our study 50 patients between 18-80 years of age was taken. Study examples were selected from people who admitted to Afyon Kocatepe University Hospital, abdominal CT scanned and verified the diagnosis of appendicitis and had an appendectomy. Patients with generalized peritonitis and perforated appendicitis were excluded. One wall thickness, lumen diameter and length of vermiform appendix, periappendicular inflammation, Hounsfield units value, appendicolith, increase in pericaecal fatty tissue, free fluid and localized lymphadenopathy were evaluated at the preoperative CT examination. Whether or not perforation during appendectomy is viewed postoperatively from the patient files. There was no postoperative perforation in 46 patients fulfilling the criteria of our study, while 4 had postoperative perforation. In our study, the mean values of some parameters of the non-perforated/perforated as has been looked; lumen diameter of vermiformis appendix 3.9 mm/6.3 mm, HU value -36.6/-6 was found. In addition, increase in pericaecal fatty tissue 73.9%/100%, periappendicular inflammation 73.9%/100% and presence of free fluid 26.1%/50% were found. Although the difference between the mean, statistically significant results weren't found between the preoperative CT values and postoperative perforation. When we look at the literature in the studies, appendiceal diameter, intraluminal fluid density, focal wall defect, appendicolith and periappendicular inflammatory changes have been associated with perforation. Perforation of acute appendicitis can lead to serious complications. We believe that the content of our study guide to the surgeon on urgent surgery of acute appendicitis.
