Clinical-Pathological Conference Series from the Medical University of Graz: Case No 166: An 82-year-old woman with voluminous diarrhea and weight loss.

In summary, surgery for acute diverticulitis typically results in colorectal anastomosis; resection of the small bowel as documented in the discussed patient is not common, but may have been necessary due to intraoperative complications.

Roskaric i : Six years prior to admission, the patient underwent surgery for an inflammatory conglomerate tumor due to complicated sigmoid diverticulitis; 28 cm of the colon and 18 cm of the small bowel were resected. Given the patient's advanced age and history of coronary heart disease and anemia, one may think of ischemic colitis in this patient; however, this diagnosis can also be ruled out because the patient denied abdominal pain. Another potential risk factor associated with recurrence of diverticulitis is an involved colon length greater than 5 cm and the presence of a retroperitoneal abscess [[23]] (in our patient, the initially affected colon segment was 28 cm in length).
