Observational assessment of anatomical variations of the appendix and their surgical relevance in complicated appendicitis cases. A cross-sectional study.

Background Anatomical variations in the position of the appendix may influence the clinical presentation, diagnosis, and surgical outcomes of complicated appendicitis. Accurate knowledge of these variations is crucial for timely intervention and improved patient outcomes. Objectives To assess the anatomical variations of the vermiform appendix and analyze their association with surgical findings and complications in patients with complicated appendicitis. Methods This observational study was conducted on 100 patients diagnosed intraoperatively with complicated appendicitis at a tertiary care hospital. Patient demographics, type of complication, appendix position, intraoperative difficulties, and histopathological findings were recorded. Data were presented using descriptive statistics and tabulated. Results The mean age of patients was 28.6 ± 10.4 years; 64% were male. Perforated appendix (39%) and appendicular abscess (27%) were the most frequent complications. Retrocecal position was the most common anatomical variant (48%), followed by pelvic (24%) and subcecal (12%). Atypical appendix positions (post-ileal and pre-ileal) were associated with delayed diagnosis, increased operative time (mean: 68.2 ± 12.7 minutes), and higher conversion rates to open surgery (39.3%). Histopathology confirmed transmural inflammation in 86% and gangrenous changes in 14% of cases. Conclusion Anatomical variations in appendix position significantly influence the severity and type of complications in appendicitis. Retrocecal and pelvic positions were most common and often associated with perforation and abscess formation, respectively. Awareness of these variations is essential for prompt diagnosis and optimal surgical management in complicated cases. Recommendations Preoperative imaging and intraoperative vigilance are recommended to anticipate anatomical variation and reduce surgical morbidity and delay.
