Underlying Colorectal Cancer Was Rarely Detected After an Episode of Acute Diverticulitis: a Retrospective Analysis of 225 Patients

The aim of the present study was to determine the prevalence of underlying colorectal carcinoma (CRC) in a cohort of patients who experienced an episode of acute diverticulitis and to assess clinical and laboratory parameters that suggest CRC diagnosis.
We performed a single center retrospective study in EMMS Nazareth Hospital from April 2014 to April 2018. All Patients who experienced an episode of acute diverticulitis and underwent a colonoscopy up to 6-month period were included in the study.
Two hundred twenty-five patients (225) patients were included. The mean age was 55.73 ± 13.81 (24–93). One hundred thirty-nine (139) patients were males. Underlying CRC was diagnosed in 2 out of 225 (0.89%) patients and colonic polyps were found in 17 out of 225 patients (7.56%). The average time interval between the episode of diverticulitis and the performance of colonoscopy was 6 weeks. Male gender was significantly associated with CRC and polyp findings (P = 0.039). Moreover, platelet count (353,000 vs. 234,000, P = 0.002) and platelet to lymphocyte ratio (223.65 vs. 127.4, P = 0.015) showed statistically significant correlation with CRC as compared to colonic polyps.
The rate of underlying CRC diagnosis was extremely low after an episode of acute diverticulitis. Male gender and platelet to lymphocyte ratio were predictors for the presence of underlying CRC.
