Table 1.
Patient classification in noncomplicated appendicitis and complicated appendicitis according to sex (Pearson's x2 test), age (Student's t-test), preoperative presentation (abdominal guarding, nausea/vomiting, and fever—Pearson's x2 test and peritonitis—Fisher's exact test), postoperative complications (superficial SSI, deep SSI, and systematic—Fisher's exact test), and preoperative sodium levels (Fischer's exact test).

| Age | Mean (SD) | 33.8 (14.7) | 45.8 (21.5) | 0.017 |
| Preoperative presentation | Abdominal guarding | 20 (32.8) | 48 (70.6) | <0.001 |
| Peritonitis | 0 (0%) | 4 (5.8%) | NS | |
| Nausea/vomiting | 28 (45.9%) | 32 (47.1%) | NS | |
| Fever | 7 (11.5%) | 10 (14.7%) | NS | |
| Preoperative sodium levels | Normonatremia | 60 (98.4%) | 40 (58.8%) | 0.001 |
| Hyponatremia | 1 (1.6%) | 28 (41.2%) | ||

NCA, noncomplicated appendicitis; CA, complicated appendicitis; SD, standard deviation; SSI, surgical site infection; NS, nonsignificant.
