BACKGROUND: The symptoms of stricturing diverticulitis can overlap with those of colorectal cancer. Additionally, the stricture itself may mask a "hidden" colorectal cancer. We aimed to describe the demographics, operative details and outcomes, including occult colorectal cancer, in a cohort of consecutive resections for presumed diverticular strictures.
METHODS: In this single-center, retrospective cohort study, all patients undergoing resection for a presumed diverticular stricture between January 2010 and December 2015 were included. Preoperative imaging and colonoscopies were individually reviewed. Only patients with radiographically, endoscopically and/or intraoperatively benign-appearing strictures were included.
RESULTS: One hundred fifty patients (72.7% female, mean age = 70.4 ± 11.8 years, 62.7% elective) were included. Only 34 (22.7%) had a complete preoperative colonoscopy. In 95 (63.6% of cohort) patients, the stricture was non-traversable colonoscopically. Overall, 47 (31.3%) patients did not have complete preoperative imaging or a colonoscopy. In total, 53.3% were open procedures and 62% had non-diverted primary anastomosis. Eleven (14.7%) underwent resection of adjacent organs (5 appendixes/5 right colons/7 fallopian tubes ± ovaries/3 small bowel resections/2 partial cystectomies/1 spleen). The median length of stay was 7 (5, 12.5) days. Only 2 cancers (1.3% of patients) involving the stricture (1 invasive moderately differentiated sigmoid adenocarcinoma/1 lymphoma) were found. Three additional cancers were found in organs involved in the inflammatory process (20% of concomitantly resected organs, 1 ovarian carcinoma/1 leukemia in a lymph node/1 appendiceal tumor).
CONCLUSION: Despite approximately one-third of the cohort not having undergone successful preoperative colonoscopy or imaging, the rate of neoplasia involving diverticular strictures was only 1.3%. A relatively high cancer rate was found in concomitantly resected organs involved in the stricturing process.
