temperature, localized pain in Mc Burney's point, tenderness, rebound tenderness), laboratory

investigations (WBC count, Leucocytosis, C-reactive protein (CRP), glycemia, serum

creatinine, SGOT, SGPT, QT, TCK, INR, urianalysis, ECG, abdominal ultrasonography,

plain abdominal X-ray, and abdominal MSCT).

3. Operative outcomes including histopathological findings (localized inflammatory APP,

purulent APP, gangrenous APP, perforative APP, apostematous APP) operative approach

(laparoscopic, open), causes of APP (fecaliths, hypertrophy of mural lymphoid follicles).

4. Post-operative outcomes including duration of postoperative hospitalization (time from

surgery to discharge), duration of total hospitalization (time from admission to discharge)

3.5.2. Data collection technique

For information regarding general information, the author and colleagues would face-to-face

interview with patients or patient's relatives. For information regarding pre-operative outcomes,

the author and skillful doctors would directly observe and examine on patients. For information

Emergency Unit and Operating Room.
