Figure 1 Postoperative complications classification and distribution in colorectal cancer patients (n = 195). A: Distribution by Clavien-Dindo classification: 122 patients (62.6%) had no complications, while 73 (37.4%) developed complications of varying severity (Grade I-IV); B: Types of complications: Anastomotic leakage (n = 19) was most common, followed by intra-abdominal infection (n = 15), intestinal obstruction (n = 12), and other complications.
