Key Points

This research aims to compare the morbidity and mortality associated with abdominoperineal resection (APR) and low anterior resection (LAR) in rectal cancer patients.
Analyzed postoperative complications in rectal cancer patients undergoing APR and LAR
Examined rates of anastomotic leakage and late complications such as pelvic abscesses and hernias
Reviewed patient demographics for associations with postoperative sepsis
Anastomotic leakage was seen in 4.67% of LAR patients with no significant statistical difference compared to APR
Two patients in the APR group developed late pelvic abscesses, while parastomal hernia was the most common complication after APR
Postoperative loco-regional sepsis was more frequent in patients over 50 and those with comorbidities, though not statistically significant

Compares morbidity and mortality outcomes in rectal cancer surgeries, suggesting implications for surgical choice.
